Description

A kind of mould structure for workpiece side punching

Technical field

The utility model relates to a kind of stamping dies, in particular to a kind of mould structure for workpiece side punching.

Background technique

In the punching course of metal works, it is frequently encountered porose situation, general precision on product shaping inclined-plane and wants When asking, shaped after general elder generation's punching.Hole site required precision is high, or when forming influences big to hole precision, shapes after first punching It not can guarantee Product Precision requirement, generally realize side blow hole machined using lifting sliding block at this time, by the fortune vertical up and down of punching machine Turn becomes the movement actually required with a vertical certain angle.But since standard lifts sliding block higher cost, and Angle specification is smaller, and when product requirement angle and inconsistent standard lifting slider angles, product cannot achieve rushing for degree of precision Pressure.

Utility model content

In consideration of it, the utility model provides a kind of mold knot for workpiece side punching that high-precision punching press may be implemented Structure.

For this purpose, the utility model provides a kind of mould structure for workpiece side punching comprising upper mold portion and lower die Portion, upper mold portion have upper die holder, are fixedly connected with upper clamp plate on upper die holder, stripper plate, stripper plate are also elasticly connected on upper die holder It is fixedly connected with diagonally disposed side blow under upper clamp plate, on upper clamp plate and enters block, offers that enter block for side blow logical on stripper plate The inclined hole crossed, side blow, which enters, is set with pressure plate on block, and the end that side blow enters block is connected with side blow needle, and lower mold portion has lower die Seat, is fixedly connected with lower module, the shape of the surface matching product of lower module on lower die holder, the surface of lower module be also provided with The jet-bedding of side blow needle cooperation.

Further, above-mentioned side blow, which enters, forms triangular cavity between the side of block and the hole wall of inclined hole.

Further, it includes first entering block and second and entering block that above-mentioned side blow, which enters block, and first one end for entering block is fixedly connected on Upper clamp plate, opposite other end elastic connection second enter block, and side blow needle is fixedly connected on first and enters on block, and second enters on block to have The through-hole passed through for side blow needle.

Further, above-mentioned first enter block and second enter block pass through the first spring connect.

Further, above-mentioned upper die holder and stripper plate pass through second spring elastic connection.

A kind of mould structure for workpiece side punching provided by the utility model, the stripper plate of traditional dies is made into It machined by the consistent sliding slot in punching direction, pacify in sliding slot in upper de- plate part with the matched angle shape in product type face Formed punch required for punching has been filled, the fixed plate of formed punch, the components such as spring required for fixed plate backing plate and de- material are fixed；? In punching course, side blow needle is fixed on pressure plate side blow and enters in block, by upper mold enter son (this enters son and is fixed on the back side of upper mold) with The contact of upper mold side blow movable block, since upper mold side blow movable block slides inside pressure plate along inclined-plane, is punched out completion；Point When mould, upper mold uplink, while side blow enters block under the action of the spring, carries out de- material completion；Therefore, in product requirement angle and mark Quasi- lifting slider angles can effectively realize the stamping press of degree of precision when inconsistent.
