Description
Technical field
The present invention relates to a kind of lock pad printed board punching die.
Background technology
Punch forming process (Punch Forming Process) applies external force by forcing press to fixing sheet material, tubing etc. in a mold, makes it produce distortion or be separated, thus make the method for processing forming of the workpiece of required form, size and performance.Punch forming process has the advantages that speed is fast, batch is large, therefore needs equipment (comprising mould) to possess higher automaticity and continuable machining accuracy.
Diel (Punch Mould) is for stamping forming mould, and in batch production at a high speed, the design and manufaction of diel can have a direct impact the quality of stamping parts and production efficiency.
Lock pad, utilizes blanking die to be formed by punching process manufacture.As the one in diel, lock pad punching blanking die has a direct impact the production efficiency and dimensional accuracy tool of locking pad product equally.But blanking die used in the related, there is punch and apply that pressure is not enough, punch part is easily stayed in sword hole, the defect of die sword wall serious wear, and this can cause the decline of punching precision and production efficiency, and the shortening of equipment life, thus cause the raising of production cost and the decline of product quality.
At manufacture printed board (Printed Circuit Board, be called for short PCB) correlation technique in, because its material is multiple Copper Foil epoxy plate, therefore when carrying out punching to PCB, there will be hole wall lamination, this not only has influence on the quality of PCB product, and can improve percent defective, because this increasing the production cost of enterprise, reduce production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of while raising punching quality and punch pressure, ensures that stamping falls into the portion of stepping down in time, and reduces the lock pad printed board punching die of die sword wall wearing and tearing.
For solving the problem, the present invention adopts following technical scheme:
A kind of lock pad printed board punching die, comprise upper bolster and die shoe, the guide pin bushing matched and guide pillar is separated with between described upper bolster and die shoe, be fixed with punch retainer below described upper bolster, be provided with punch and stripper below described punch retainer, described punch is passed down through described stripper, the top of described die shoe is fixed with die, described die is provided with cutting edge, and described die matches with described punch, is provided with elastic device between described upper bolster and described stripper.
Lock pad printed board punching die according to the present invention is provided with elastic device, larger pressure-plate-force can be applied when carrying out punching technology, therefore, it is possible to prevent PCB from occurring hole wall layering, improve punching quality, thus improve PCB product quality and technology stability.
In addition, lock according to the present invention pad printed board punching die is provided with elastic device and can also has following additional technical feature:
Preferably, described elastic device is made up of more than one spring.Multiple spring (1) can apply larger pressure-plate-force when discharging to stripper; (2) relative to the single-point elastic force of a spring, multiple spring can be distributed in the diverse location of punch retainer, is multiple spot elastic force to stripper, prevents the discharging of one direction elastic force, damage product.Unloading bolt is provided with, with fixing described punch retainer between described punch retainer and stripper.Spring in described elastic device can be through on described unloading bolt, also can not be through on described discharging screw.In addition, be provided with the first gap between described punch retainer and described stripper, the upper end of described elastic device is fixed on described punch retainer, and leave the second gap between lower end and described stripper, the second gap is less than the first gap.Like this, when the die is closed, elastic device does not produce stripper or produces less elastic force, and to increase pressure during matched moulds, when die sinking, elastic device produces elastic force to stripper, plays discharging effect.
Preferably, described spring is provided with four.
Preferably, the sword wall of cutting edge is provided with gradient.Like this, ensure that stamping can in time by sword hole, enter the portion of stepping down, and the gap produced when matched moulds by punch and die reduces the wearing and tearing to die sword wall, improves punching precision and production efficiency.
Preferably, the tip section size of described punch is less than the cutting edge sectional dimension of die.Like this, pressure is improved.
Preferably, described die is also provided with location slightly.
Preferably, described upper bolster is provided with die shank.
Preferably, described guide pin bushing and guide pillar are all provided with two and are symmetrical arranged between upper bolster and die shoe.
Additional aspect of the present invention and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present invention.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present invention and advantage will become obvious and easy understand from accompanying drawing below combining to the description of embodiment, wherein:
Fig. 1 is a kind of plane locking pad printed board punching die of the present invention;
Fig. 2 is a kind of A portion enlarged drawing locking pad printed board punching die of the present invention.
description of reference numerals:
Upper bolster 1; Die shoe 2; Guide pin bushing 3; Guide pillar 4; Elastic device 5; Spring 6; Die shank 7; Punch retainer 8; Punch 9; Stripper 10; Die 11; Location slightly 12.
Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
In describing the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, such as, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be.
Referring to Fig. 1,2, the one lock pad printed board punching die according to the embodiment of the present invention is described, the lock pad printed board punching die of the present embodiment, comprises upper bolster 1, die shoe 2, guide pin bushing 3, guide pillar 4, elastic device 5, spring 6, die shank 7, punch retainer 8, punch 9, stripper 10, die 11 and location slightly 12.
