Abstract
The invention discloses a kind of power punch structure of semiconductor bar shearing former, comprise dynamical system main shaft, power drift, drift screw, described power drift is connected with dynamical system main shaft by drift screw, described dynamical system main shaft stage casing cover has force bearing plate, described force bearing plate circumference encloses and is respectively arranged with buffer screw, and on described buffer screw, all cover has the buffer spring of equal precompression.The present invention can reduce the noise in blanking process; The vibrations of power drift can be reduced, improve the stability of punching molding size; When there is misoperation, the damage probability of malfunction of power drift to reductor, servomotor and dynamical system greatly can be reduced; Adopt bolt structure, die-cut moment can be regulated according to service condition.
Description
Technical field
The present invention relates to semiconductor bar shearing former field, be specifically related to a kind of power punch structure of semiconductor bar shearing former.
Background technology
In semiconductor bar shearing equipment normally runs, the quality of dynamical system is the stability of decision device and reliability largely.And the power that dynamical system finally exports all relies on power drift to export to Trim Molding mould.
Existing power drift and Trim Molding mould are all rigidly connected, nonelastic buffer protection structure.In blanking process, the noise that drift and Trim Molding mould produce is very large; Simultaneously because power drift and Trim Molding mould are rigidly connected, during punching molding easily there is deviation in size, and defect rate is higher; And nonelastic buffer protection structure, once misoperation, there is no buffer protection, very easily occur the damage of reductor, servomotor and dynamical system.
Summary of the invention
For the problems referred to above, the present invention aims to provide a kind of power punch structure of the semiconductor bar shearing former little with the safe noise of buffer structure.
For realizing this technical purpose, the solution of the present invention is: a kind of power punch structure of semiconductor bar shearing former, comprise dynamical system main shaft, power drift, drift screw, described power drift is connected with dynamical system main shaft by drift screw, described dynamical system main shaft stage casing cover has force bearing plate, described force bearing plate circumference encloses and is respectively arranged with buffer screw, and on described buffer screw, all cover has the buffer spring of equal precompression; Described force bearing plate is also connected with correcting post, is also provided with guide sleeve below correcting post, and described guide sleeve and correcting column sleeve are on drift screw.
As preferably, described power punch head is trapezium structure, spherical or flat shape structure.
As preferably, described buffer screw arranged outside has housing to be covered on wherein, and at dynamical system main shaft and buffer screw place, in housing, correspondence is provided with counterbore respectively.
Beneficial effect of the present invention, described power punch structure connects with elasticity adjustable force moment again, during use, can be reduced the noise in blanking process by the cushioning effect of spring; And due to the stabilization of spring, the vibrations of power drift can be reduced, improve the stability of punching molding size; Meanwhile, when occurring misoperation, because the cushioning effect of spring greatly can reduce the reaction force of power drift to reductor, servomotor and dynamical system, reducing it and damaging probability of malfunction; Adopt bolt structure, die-cut moment can be regulated according to service condition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, specific embodiment of the present invention is a kind of power punch structure of semiconductor bar shearing former, comprise dynamical system main shaft 1, power drift 3, drift screw 2, described power drift 3 is connected with dynamical system main shaft 1 by drift screw 2, described dynamical system main shaft 1 stage casing cover has force bearing plate 4, described force bearing plate 4 circumference encloses and is respectively arranged with buffer screw 8, on described buffer screw 8, all cover has the buffer spring 7 of equal precompression, and described buffer screw 8 arranged outside has housing 9 to be covered on wherein; Described force bearing plate 4 is also connected with correcting post 5, and correcting post 5 is also provided with guide sleeve 6 below, and described guide sleeve 5 and correcting post 6 are enclosed within drift screw 2.When power ram impacts mould, power drift can be subject to the reaction force of mould, and spring fixing on force bearing plate, owing to being provided with prestressing force, deformation can not occur under normal impact, ensures that blanking process completes normally; When causing reaction force excessive when breaking down, spring can absorb impulsive force, makes power drift that vibrations occur and offsets minimizing, and reduces owing to shaking, and noise during impact also can be less.Wherein, guide sleeve and correcting post can ensure that drift screw and drift force bearing plate keep same direction to move, and make spring better absorb reaction force.
Six positions that four positions that three of described force bearing plate 4 circumference trisection posistion are respectively arranged with buffer screw 8 or the force bearing plate 4 circumference quartering are not provided with buffer screw 8 or force bearing plate 4 circumference six decile are respectively arranged with buffer screw 8.Arranging many group springs can keep whole drift screw to be all in stable buffer environment, improves damping effect.Described power drift 3 front end is trapezium structure, spherical or flat shape structure, and this structure is more stable, impacts more steady.
Described buffer screw 8 arranged outside has housing 9 to be covered on wherein, and at dynamical system main shaft 1 and buffer screw 8 place, in housing 9, correspondence is provided with counterbore 10 respectively.Housing can better protect dynamical system main shaft and buffer screw not to be affected by the external environment.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
