Description

The split type die sleeve of a kind of straight die shank
Technical field
The utility model relates to diel part field, is specifically related to the split type die sleeve of a kind of straight die shank.
Background technology
Sheet Metal Forming Technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, in economy and technical elements, all there is a lot of advantages, it is easy and simple to handle, be convenient to realize mechanization and automation, be suitable for the production of part more in enormous quantities, its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So, it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation, in the middle of punching production, diel is as the concrete executing means of Sheet Metal Forming Technology, nature attention, in fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.
Because little punch press kind is more, slider of punch mould installing hole is not of uniform size, and die shank thickness model is also more, mould can not exchange between punch press, poor universality, sometimes needs to lay in multiple die shank, complete use by the method changing mould grip, be inconvenient to like this produce.
When small size stamping parts is produced, mould pins down by slider bore size often to be needed to use fixing punch press, run into as used mould the punch press damage of mating or without suitable punch press resource time, work can be caused passive or delay the duration.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of straight die shank split type die sleeve for above drawback, and structure is simple, is directly linked on die shank, highly versatile, adds service life, saved cost.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The split type die sleeve of a kind of straight die shank, comprise the first die sleeve and the second die sleeve, described first die sleeve and the second die sleeve are split-type structural, the cross section of described first die sleeve and the second die sleeve is arc-shaped structure, and the radius r 2 of radius r 1=second die sleeve of the first die sleeve, the radian b of radian a=second die sleeve of the first die sleeve, two sides of described first die sleeve are respectively the first contact surface and the first clearance plane, two sides of the second die sleeve are respectively the second contact surface and the second clearance plane, described first contact surface and the second contact surface be arranged in parallel, angle c=130 ° between the tangent line of the first contact surface and the first die sleeve, angle d=90 ° between the tangent line of the first clearance plane and the first clearance plane, angle e=90 ° between the tangent line of the second clearance plane and the second clearance plane, first contact surface of described first die sleeve and the second contact surface of the second die sleeve cooperatively interact and make entirety form an inc annulus,
Described first contact surface is provided with the clamping raised line that cross section is circular arc, and the second contact surface is provided with the clamping groove that cross section is circular arc, the central angle f=130 ° that the circular arc of clamping groove is right, described clamping raised line and clamping groove matched in clearance;
The inwall of described first die sleeve and the second die sleeve is respectively provided with in one and regulates passage, and the outer wall of the first die sleeve and the second die sleeve is respectively equipped with two and regulates passage outward, and described interior adjustment passage and outer adjustment passage are interspersed.
The utility model beneficial effect is:
1. the utility model adopts split-type structural, can direct splicing formula be linked in die shank outside, in order to increase the external diameter of die shank, structure is simple, and highly versatile, has saved cost;
2. the first contact surface and the second contact surface be arranged in parallel, and the angle c=130 ° between the tangent line of the first contact surface and the first die sleeve, and when two contact surfaces contact with each other, laminating is relatively tightr, can not slippage easily, ensure that its stability;
3. the angle d=90 ° between the tangent line of the first clearance plane and the first clearance plane, angle e=90 ° between the tangent line of the second clearance plane and the second clearance plane, after can ensureing that two die sleeves are bonded to each other, clearance plane can not contact with each other, leave certain cushion space, therefore in use can not cause damage because of other factors such as vibrations, add service life;
4. the first contact surface is provided with the clamping raised line that cross section is circular arc, second contact surface is provided with the clamping groove that cross section is circular arc, and both cooperatively interact, and namely can ensure the flatness that both are bonded to each other, there is again certain surplus, the die shank of different size can be applicable to;
5. regulate being crisscross arranged of passage and outer adjustment passage in, add buffer capacity to a certain extent, add service life.
