Detailed description of the invention
Referring to figs. 1 through Fig. 4, the present embodiment is described further.
A kind of perforating press, comprise frame 1, upper bolster 5, be fixed on the die shoe 7 in frame 1 and drive unit, drive unit is fixedly installed in frame 1 and drive unit drives upper bolster 5 to move up and down, herein about the selection of drive unit, the present embodiment is preferably cylinder 2, and between upper bolster 5 and die shoe 7, the present embodiment adopts and arrange guide pin bushing 3 on upper bolster 5, die shoe 7 arranges the guide pillar 4 be socketed with guide pin bushing 3, thus the relative motion of upper bolster 5 and die shoe 7 can be realized, and in order to the object of punching can be realized, upper bolster 5 is provided with drift 10, along with moving up and down of upper bolster 5, the punching to workpiece can be realized.
And when after drift 10 hole punch, workpiece to move upward one end distance together along with drift 10.Therefore, in order to overcome this problem, the present embodiment adopts and on upper bolster 5, arranges lower end be opening and length is greater than the hollow elastomer block 6 of drift 10 length, and drift 10 is positioned at hollow elastomer block 6, along with cylinder 2 drives upper bolster 5 to move, first hollow elastomer block 6 can arrive with absorption surface, thus cause hollow elastomer block 6 to be out of shape, and hollow elastomer block 6 is set to annular due to the present embodiment, because after hollow elastomer block 6 is out of shape, side due to annular is smooth curved surface, also just ensure that the sidewall of hollow elastomer block 6 is uniform force everywhere, can effectively prevent excessive due to somewhere stress and hollow elastomer block 6 that is that cause is damaged.After punching completes, cylinder 2 drives upper bolster 5 to move towards the direction away from die shoe 7, and before drift 10 departs from workpiece, can produce after distortion due to hollow elastomer block 6 one make workpiece against die shoe 7 on power, being separated therefore along with drift 10 and workpiece, workpiece can not move upward together along with drift 10, can effectively reduce the noise produced in production process, and in whole process, between workpiece and die shoe 7, also can not produce shock.In addition; due to hollow elastomer block 6 by drift 10 to surrounding; therefore, it is possible to effectively prevent the thing of some moisture and so on be splashed on drift 10 and cause drift 10 to get rusty; and after drift 10 is clashed into; the existence of hollow elastomer block 6 also can play certain cushioning effect, plays certain protective effect to drift 10.Overall structure is also very simple simultaneously, low cost of manufacture.
And due to hollow elastomer block 6 with abut and conflict after, hollow elastomer block 6 is easy to towards side expansion, thus causes hollow elastomer block 6 larger at lower ending opening, the time grown after the elastic force of hollow elastomer block 6 can be caused to decline.Therefore in order to the service life of hollow elastomer block 6 effectively can be improved, the present embodiment selects sheathed sliding shoe 8 on drift 10, and between hollow elastomer block 6 and sliding shoe 8, be connected with contiguous block 9, and as a preferred version, the junction of hollow elastomer block 6 and contiguous block 9 is near the lower surface of hollow elastomer block 6, after such setting, in time wanting to uphold towards both sides after deformation appears in hollow elastomer block 6, the existence of contiguous block 9, can effectively prevent hollow elastomer block 6 from upholding towards both sides, and contiguous block 9 be set to multiple and distribute around drift 10 uniform circular time best results.And be socketed due to sliding shoe 8 and drift 10, therefore in the process of drift 10 punching, when sliding shoe 8 arrives with absorption surface time, sliding shoe 8 there will be slip, can not have influence on the normal work of drift 10.
