Description

Two-die three-stroke stamping machine

The invention relates to the design of a stamping forming machine, in particular to a two-die three-stroke stamping forming machine.

In order to effectively improve the lack of slow turning processing speed when making parts, cold forging stamping and forming methods will be used for large-scale processing. At the same time, depending on the completion of the processing and forming of the parts, choose to have multiple punching dies. The punching and forming machine is carried out; referring to Figure 1, the conventional punching and forming machine 1 includes a machine table 11, which is separately provided with a feeding unit 12, a forming die unit 13, a punching die unit 14 and a clamping unit 15 (in the figure) In a simplified diagram); wherein, the feeding unit 12 has a cutting and feeding part 121, which can cut and feed an output metal material 2 according to the specifications; in addition, the forming mold unit 13 has a plurality of pieces set in the The molding die 131 on the main body 11 is used for placing the metal material 2; and the punching die unit 14 has a number of punching dies 141 set corresponding to the molding die 131 to perform the metal material 2 in the molding die 131. Stamping (the figure is marked with three corresponding forming dies and punching dies); As for the clamping unit 15 between any two forming dies 131, there is a clamping piece 151, which will be used for the next stamping operation. The metal material 2 is clamped and transferred, and there are at least three molding dies 131 in the prior art, so the clamps 151 are provided in two.

Therefore, when performing the stamping and forming operation of the part, the cutting feeder 121 will cut the output metal material 2 according to the set specifications and dimensions, and transport it to the adjacent first forming mold 131a to correspond to the first forming mold 131a. A punching die 141a performs the first punching of the metal material 2 on the first forming die 131a. After completion, the first punching die 141a will exit the first forming die 131a, which is now located in the first and second forming molds. The first clamping 151 between the molds 131a and 131b will clamp the metal material 2 that has completed the first stamping, and move to the second forming mold 131b for the second stamping, even by the second stamping The two clamping members 151' clamp the second forming die 131b to receive the metal material 2 to complete the second stamping of the second die 141b, and then continue to be transferred to the third forming die 131c, and receive the second stamping die 141b. The third stamping operation of the three-punch die 141c enables the metal material 2 to effectively form the appearance of the part through multiple stamping processes.

However, although each forming die 131 has a corresponding die 141, it can effectively perform multiple stamping forming of the metal material 2 at the same time. However, after actual use, it is found that the stamping forming machine 1 requires a larger size space. The punching die 141 and the forming dies 131 can be effectively set thereon, and there must be a clamping piece 151 between the punching dies 141, so every time the punching die 141 is punched, the clamping piece must be carried out. Over-clamping of 151 can easily cause errors in the metal material 2 during multiple clamping of the clamping member 151, which affects the stamping process and forming operations. In view of this, I filed a patent application in this case.

Therefore, the object of the present invention is to provide a two-die three-stroke press forming machine, which can utilize the rotation of a rotating part to appropriately adjust the position of any two punching dies relative to the second forming die of the forming die unit, so that each The metal material in the forming die seat can be surely subjected to at least two stamping effects, which not only can effectively reduce the number of clamping passes to increase the processing speed, but also greatly increase the smoothness of the stamping operation.

Therefore, the two-die three-stroke press forming machine of the present invention includes a body, and a feeding unit, a forming die unit, a punching die unit, and a clamping unit separately arranged on the body; wherein, the punching die unit has a movable seat, a A rotating part arranged on the movable seat, and at least three dies arranged on the rotating part at intervals, and at least any two of the dies are opposed to the two adjacent forming die bases of the forming die unit, and the dies are at the same time Under the rotation of the rotating part, the position of any two different punching dies relative to the two forming mold bases can be adjusted; therefore, by the design of the rotating part on the movable base, the rotating part can be rotated during the rotation process. Adjust and transform any two of the punching dies set above to correspond to the two forming mold bases, so that each metal material located on the forming bases accepts at least two different punching operations of the punching die, which not only reduces each The movement of a metal material can effectively increase the processing speed, and can greatly improve the success rate of multiple stamping forming, so as to reduce the number of clamping and passing molds during stamping and forming operations, and effectively avoid the lack of accurate positioning during the moving process. , In order to achieve the smoothness of stamping and forming operations.

The foregoing and other technical content, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.

2, a preferred embodiment of the present invention includes a body 31, and a feeding unit 32, a forming die unit 33, a die unit 34, and a clamping unit 35 separately provided on the body 31; wherein, the feeding unit The unit 32 can convey and feed a metal material 4, and at the same time has a cutting and feeding piece 321, which can cut the output metal material 4 according to the required specifications, and convey it at the same time In addition, the forming die unit 33 is located on one side of the feeding unit to receive the metal material 4 output by the feeding unit 32, and corresponds to the punching die unit 34, and the forming die unit 33 has at least Two adjacent forming mold bases 331, and each of the forming mold bases 331 can accommodate the metal material 4 after cutting. Hereinafter, at least two of the forming mold bases 331 are divided into first and second forming molds, respectively The seats 331 and 331' are taken as an example; as for the die unit 34, the die unit 34 has a movable seat 341 provided on the main body 31, a rotating member 342 provided on the movable seat 341, and at least three spaces are separately provided on the The punching die 343 on the rotating part 342 is controlled by the rotation of the rotating part 342 to adjust and change any two. The punching die 343 corresponds to the second molding die 331 so that the metal material 4 on the second molding die 331 is more For the stamping of different dies, at least three dies 343 are divided into first, second, and third dies 343, 343A, and 343B as an example. At the same time, the aforementioned dies 343 and forming die holders 331 can be used as desired. The shapes of the molded parts are designed in different shapes and specifications; as for the clamping unit 35 is located between the two forming mold bases 331, the metal material 4 is held between the two forming mold bases 331 for different stamping processes.

Referring to Figures 3a-3b, firstly, you can set the processing program for the parts to be stamped and formed. It can be set to perform secondary stamping and forging on the first forming die seat 331 by a different die 343, or in The second forming die seat 331' is carried out by a different die 343 Secondary stamping and forging (the following is to take the second different stamping on the second forming die seat as an example). After the setting is completed, the stamping operation can be carried out, that is, the feeding unit 32 will transfer the metal material 4 At the same time, the cutting and feeding part 321 will be cut according to the size of the part to be stamped and formed, and the cut metal material 4 is fed to the first forming mold base 331. At this time, the The dies 343 on the rotating part 342 will adjust the first and second dies 343, 343A and the first and second molding die seats 331, 331 under the rotation of the rotating part 342, and the The third die 343B does not correspond to any one of the molding die holders 331, 331', and then the movable seat 341 will drive the first and second die 343, 343A to the corresponding one under the actuation of the driving force. The first and second forming mold bases 331, 331' are punched so that the metal material 4 located in the first forming mold base 331 for the first time is punched for the first time, showing a partial appearance of the part. When the first stamping operation is completed, the die 343 will be driven by the moving seat 341 to exit to escape from the forming die unit 33, and then the clamping unit 35 will immediately target the first forming die. The metal material 4 that has been punched for the first time on the mold base 331 is clamped and moved to the second molding mold base 331', and the first molding mold base 331 is also affected by the cutting feed piece 321 Replenishing the feed. At this time, the first and second die 343, 343A will be driven by the moving seat 341 to move to the corresponding first and second molding die seats 331, 331', and when they exit after punching again , And the rotating member 342 will rotate when the die 343 is withdrawn, so as to immediately change the position of the third die 343B corresponding to the second molding die seat 331' (as shown in Figures 4a-4b) Under the rotation adjustment of the rotating member 342, the third die 343B, which has completed the position change, is moved quickly on the metal material 4 in the second molding die seat 331' during the movement of the movable seat 341. The stamping and forging of the punching die completes the overall appearance of the part to be formed by stamping the metal material 4 through two dies and three punches.

Therefore, through the rotating part 342, the corresponding punching dies 343 and the forming die holders 331 can be appropriately adjusted and transformed, so that multiple punching and forging designs of different punching dies can be performed at the same time, which can not only reduce the clamping during the punching and forming operation. The number of over-moulding is more accurate and smoother, and it is more conducive to directly picking up the metal material 4 that cannot be clamped by the clamping unit 35 for multiple over-moulding. After that, the stamping and forging of different punching dies are performed twice simultaneously, and the parts that need to be stamped and forged, such as different head types, or directionality, and positioning functions, can all be formed by the design of the present invention. To complete and meet the requirements of special processing operations, not only can the production of defective products due to the movement error of each metal material 4 be reduced, but also the fixture settings can be reduced, the processing speed can be effectively increased, and the multiple stamping forming can be greatly improved. The success rate is to reduce the lack of accurate positioning during the moving process, so as to facilitate the smoothness of the stamping and forming operation.

To summarize the foregoing, the two-die three-stroke press forming machine of the present invention mainly uses the design of at least three dies on the rotating part on the movable seat that are separately arranged on the rotating part, and by appropriately controlling the rotation of the rotating part Rotate to properly adjust and change the position of any two punching die relative to the second molding die base of the molding die unit, so that the metal material in each molding die base can be reliably received at least two times while reducing the clamping movement. The second stamping effect can not only effectively increase the processing speed, but also reduce the number of clamping and over-molding during the stamping and forming operation, and it can greatly increase the smoothness of the stamping and forming operation.
