Abstract
The invention relates to a plastic strip cold punching device with a protection plate, which consists of an upper mold and a lower mold, wherein the upper mold consists of an upper mold seat, a mold handle, a guide sleeve, a male mold and a male mold fixing plate, the lower mold consists of a female mold, a guide post, a protection plate and a lower mold seat, and the upper mold and the lower mold are matched and connected through the guide sleeve and the guide post. Compared with the prior art, the plastic strip cold punching device has the advantages that the male mold adopts the inclined surface design, the male mold becomes a sharp cutter blade, and the contact area of a mold punching notch and a punching element is reduced, so the cut surfaces of plastic strips are smooth and flat, the mold completes the punching under the condition without a great load, the service life of the mold is prolonged, the protection plate additionally arranged on the female mold of the lower mold can prevent the fingers of operators from sliding into the mold punching work region, and the safety of the equipment operation is enhanced.
Description
Technical field
The present invention relates to a kind of blanking units, especially relate to a kind of blanking units of the plastic strip part being processed with protective plate.
Background technology
The processing of plastic strip at present generally adopts cold-punching mold to carry out die-cut to plastic strip; Punching tool in the cold punching mill mould is generally the plane knife face, and in order to reduce the friction of knife face and other parts, traditional cold-punching mold keeps certain intervals with interior other parts of cutter and device; But because cutter is thinner; More easy to wear, thus make the die-cut part that comes out phenomenons such as burr occur, influenced the quality of product.
Summary of the invention
The object of the invention is exactly the plastic strip cold punching device that provides a kind of in order to overcome the defective that above-mentioned prior art exists and increase service life, improves the band protective plate of die-cut quality, handling safety.
The object of the invention can be realized through following technical scheme:
A kind of plastic strip cold punching device with protective plate is characterized in that this cold punching device is made up of upper die and lower die, and described patrix is provided with two dowel holes, and two guide pin bushings are set on the described counterdie, and patrix and counterdie are connected through guide pin bushing and guide pillar.
Described patrix is made up of upper bolster, die shank, guide pin bushing, punch and punch retainer, and described die shank is located at the top of upper bolster, and described guide pin bushing has two, is opened in a side of upper bolster, and described punch is connected the bottom of upper bolster through punch retainer.
Described punch retainer bottom embeds punch, and top is connected the bottom of upper bolster through fixed screw and alignment pin.
Described counterdie is made up of die, guide pillar, protective plate and die shoe, and described die is located at the top of die shoe, and described guide pillar has two, is located at a side on die shoe top, and described protective plate is located at the top of die.
Described die is fixed on the die shoe through fixed screw and alignment pin.
The top of described die is offered and the corresponding die of punch shape and position hole, a side in die hole be provided with plastics towards the identical charging aperture of part end surface shape.
The middle part of described die shoe is provided with the material-dropping hole of up/down perforation.
Compared with prior art, the punch among the present invention is to adopt inclined design, and punch becomes sharp blade; The punch die edge of a knife and stamping parts contact area reduce, and make the disconnected tangent plane of plastic strip bright and clean concordant, mould need not to have accomplished under the situation of heavy load very die-cut; Prolonged the service life of mould, set up a protective plate on the die of counterdie, operating personnel are when handing towards the part feeding; Prevented that the finger slip is strayed in the punch die workspace, increased the security of equipment operation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a counterdie plan structure sketch map.
Wherein: 1-die shank, 2-fixed screw, 3-upper bolster, 4-guide pin bushing, 5-alignment pin, 6-punch retainer, 7-punch, 8-guide pillar, 9-die hole, 10-charging aperture, 11-protective plate, 12-die, 13-die shoe.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of plastic strip cold punching device with protective plate, its structure is as shown in Figure 1, and this cold punching device is made up of upper die and lower die; Patrix is made up of die shank 1, upper bolster 3, guide pin bushing 4, punch retainer 6 and punch 7; Die shank 1 is located at the top of upper bolster 3, and guide pin bushing 4 has two, is opened in a side of upper bolster 3; The bottom of punch retainer 6 embeds punch 7, and top is connected the bottom of upper bolster 3 through fixed screw 2 and alignment pin 5.The structure of counterdie is as shown in Figure 2; Be made up of guide pillar 8, protective plate 11, die 12 and die shoe 13, die 12 is located at the top of die shoe 13, is fixed on the die shoe 13 through fixed screw 2 and alignment pin 5; The top of die 12 is offered and the corresponding die of punch 7 shapes and position hole 9; One side in die hole 9 be provided with plastics towards the identical charging aperture 10 of part end surface shape, guide pillar 8 has two, is located at a side on die shoe 13 tops; Protective plate 11 is located at the top of die 12, and the middle part of die shoe 13 is provided with the material-dropping hole of up/down perforation.Patrix and counterdie are connected through guide pin bushing 4 and guide pillar 8.
During use; At first plastic strip is put into die 12 by charging aperture 10; The forcing press that drives peripheral hardware presses down die shank 1 makes upper bolster 3 press down along guide pillar 8; Be arranged on upper bolster 3 bottoms punch 7 enter into the die hole of offering on the corresponding die 12 9, the plastic strip that is placed on the inside is die-cut into needed shape, the through hole that the die-cut waste material that comes out is offered through die shoe 16 middle parts drops out.
