Detailed description of the invention
As shown in Figure 1 and Figure 2, be respectively front view and the top view of carbon slipper bracket bending roll machine of the present utility model, as seen from the figure, carbon slipper bracket 5 bending roll machine of the present utility model comprises: frame 1; Be installed on a pair support roller 2,3 for support carbon slipper bracket 5 in frame 1 side by side; To be installed in frame 1 and the down-pressure roller 4 for pressing down carbon slipper bracket 5 be positioned at above a pair support roller 2,3; For driving the drive unit of a pair support roller 2,3 and down-pressure roller 4 synchronous rotary; Wherein, the equal diameters of a pair support roller, and down-pressure roller 4 symmetrical centre is less than down-pressure roller 4 diameter and any one support roller diameter sum to the vertical range of a pair support roller 2,3 line of centres, thus when a pair support roller 2,3 and down-pressure roller 4 synchronous rotary, while carbon slipper bracket 5 is carried out roll bending process, carbon slipper bracket 5 can be transported forward.
Wherein, as shown in Figure 1, the roller shaft of a pair support roller 2,3 is positioned at same level, and the roller shaft of down-pressure roller 4 is positioned at directly over the roller shaft line of centres of a pair support roller 2,3.In order to make bending roll machine of the present utility model bracket roll bending can be processed into different radians, the spacing between the line of centres of the roller shaft of down-pressure roller 4 of the present utility model and the roller shaft of a pair support roller 2,3 can regulate.
Wherein, down-pressure roller 4 of the present utility model and a pair support roller 2,3 synchronous rotary under the driving of drive unit, and drive unit of the present utility model can adopt gear drive, also belt drive unit can be adopted, certainly, the transmission device that can drive three roller synchronous rotaries of the prior art can also be adopted.
Below, adopt loading drive gear to be set to example with drive unit, its structure is described.As shown in Figure 1-Figure 3, drive unit of the present utility model can comprise: motor 21; The input gear 6 be connected with the output shaft of motor 21, this input gear 6 can directly be fixedly installed on the output shaft of motor 21, also can be fixedly installed in motor 21 carry out slow down process reduction box 22 output shaft on (as shown in Figure 2); A pair fixed gear 7,11 be connected with a joggle with input gear 6, correspondence is installed on a pair fixed gear axle 8,12; The movable gear shaft 19 be in transmission connection with input gear 6; Wherein, a pair support roller 2,3 is installed on a pair fixed gear axle 8,12 (this pair fixed gear axle is the roller shaft of above-mentioned a pair support roller 2,3) respectively, and down-pressure roller 4 is installed on movable gear shaft 19 (this movable gear shaft is the roller shaft of above-mentioned down-pressure roller).
Wherein, the spacing between the roller shaft of down-pressure roller 4 and the line of centres of the roller shaft of a pair support roller 2,3 is regulated to realize by the following method, that is, down-pressure roller can be regulated relative to the method for the vertical height of support roller by making the vertically highly constant of a pair support roller.Accordingly, in order to regulate the vertical height of down-pressure roller, drive unit of the present utility model also needs the spacing adjusting part comprised for regulating spacing between movable gear shaft 19 and fixed gear axle 8,12.
Preferably, as shown in Figure 3, spacing adjusting part can comprise: be arranged on the travelling gear 17 on the input wheel shaft 9 of input gear 6; The self adaptation gear 15 be connected with a joggle with travelling gear 17, is installed on self adaptation axle 16; The adaptive connection plate 13 be rotationally connected respectively with input wheel shaft 9 and self adaptation axle 16; The moving gear 17 be connected with a joggle with self adaptation gear 15, it is installed on movable gear shaft 19; The adjustment connecting plate 14 be connected respectively with self adaptation axle 16 and movable gear shaft 19.
Further, spacing adjusting part also comprises for promoting the boost assemblies of movable gear shaft 19 relative to the movement of input wheel shaft 9, and it comprises: the activity box 18 for supporting movable gear shaft 19 be rotationally connected with movable gear shaft 19; Be installed on the bracing frame 23 in frame 1; Adjustment screw mandrel 20 (not shown) that its one end is fixedly connected with activity box 18, its other end straight up through bracing frame 23, and is threaded with bracing frame 23.Regulating screw mandrel 20 for the ease of turning, regulating the other end of screw mandrel 20, handle 24 being also installed.
When needed for bracket, the vertical range of radian to down-pressure roller opposed pair support roller regulates, (state when namely motor does not work) turns and regulates screw mandrel 20 in the quiescent state, make it screw in or screw out bracing frame 23, drive the activity box 18 be fixedly connected with it vertically to move up or down, thus the movable gear shaft 19 be installed in activity box 18 is moved up or down thereupon, because down-pressure roller 4 is fixedly installed on movable gear shaft 19, drive the moving gear 17 fixedly mounted thereon and down-pressure roller 4 to move when movable gear shaft 19 moves, and movable gear shaft 19 is connected with self adaptation axle 16 by adjustment connecting plate 14, therefore, when movable gear shaft 19 moves, moving gear 17 can be changed and be fixedly installed in the position of engagement between the self adaptation gear 15 on self adaptation axle 16, and self adaptation gear 15 and travelling gear 17 are connected with a joggle, and self adaptation axle 16 is connected with input wheel shaft 9 by adaptive connection plate 13, thus self adaptation axle 16 and self adaptation gear 15 can be rotated around input wheel shaft 9, and moving gear can rotate around self adaptation axle, to reach the object of the spacing regulated between movable gear shaft and input wheel shaft.Certainly, regulate the spacing between movable gear shaft and input wheel shaft can also be realized by other kind of drive of the prior art, its structure is not described at this.
It should be noted that, bracket of the present utility model can adopt metal to make, if bracket is aluminum bracket, and down-pressure roller and support roller can adopt duroplasts to make, thus guarantee not cause damage (as cut etc.) to bracket surface when carrying out roll bending process to bracket.Preferably, down-pressure roller and support roller all adopt dismountable mode to be connected with movable gear shaft and fixed gear axle respectively.
To sum up, carbon slipper bracket bending roll machine of the present utility model, structure is simple, can realize the automatic roll bending process to carbon slipper bracket by a pair support roller and down-pressure roller, only needs a workman when operating, and saves artificial and enterprises using the labor cost; And the spacing of the relative support roller of down-pressure roller can regulate, thus different radians required when can meet bracket roll bending, and the arc of the bracket product formed after roll bending process is stablized, good product consistency, improves the quality of production and production efficiency; Down-pressure roller and support roller all removably connect with gear shaft, thus can change different rollers according to the cross sectional shape of bracket, make a tractor serves several purposes, save enterprise procurement cost.
Although be explained in detail the utility model above; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
