Description

A kind of bending progressive die
Technical field
The present invention relates to stamping mold field, and in particular to a kind of bending progressive die.
Background technology
The process of scientific technological advance represents that mechanical industry is the important carrier that science and technology turns materially productivity, and mould Tool design occupies very important status with manufacture in machinery industry.At present, the product such as electronics, automobile, motor, household electrical appliances and military project In, the parts of 60%-80% will rely on mould molding.The high accuracy showed with formed in mould product, Gao Fu Polygamy, uniformity high and low consumption, are that other machining manufactures are incomparable, and mould largely decides product Quality, benefit and development ability.
Typically completed by bender for traditional simple bending technique, then typically passed through for multiple working procedure bending technique Progressive die realization, can so produce in batches, improve production efficiency, reduce production cost, but further to bending technique Research, it is found that bending mainly completes obtuse angle bending of the angle more than 90 degree on existing market, and for needing 90 degree of bending techniques Or the bending technique less than 90 degree implement it is then very few, generally require secondary operation just be capable of achieving, increased shaping Step, is unfavorable for that enterprise produces in batches.
The content of the invention
In order to solve above-mentioned problem, the present invention provides a kind of bending progressive die, and the bending progressive die can be realized Bending angle≤90 ° bending technique, for batch production provides feasible scheme.
The present invention is for the used technical scheme that solves the above problems:A kind of bending progressive die, including upper module are provided With lower module, the upper module includes stripper and the discharging backboard, spring, fixed plate, solid being successively set on the upside of stripper Determine backing plate, upper bolster and top mold frame;The lower module include concave template and be successively set on the downside of concave template cavity plate backing plate, under Die holder and bottom seat pad;Multipair upper punch is provided with the fixed plate, each pair upper punch uses gap by circular hanging platform Cooperation is fixed in fixed plate, is provided with sliding block, outside workpiece raw material on the concave template with each pair upper punch position corresponding position Fed between stripper and concave template, by upper and lower module punch forming so that the corresponding sliding block of each pair upper punch Coordinate to workpiece raw material bending and molding so that 90 ° of workplace vertical side angle=after shaping.
Due to being gap cooperation between upper punch and circular hanging platform, then upper punch then can be along the center of circular hanging platform Axle is swung, in other words, upper punch pendulum angle can with≤90 °,
Respective design is carried out by hole slot on the discharging backboard and stripper that run through to upper punch so that its hole slot border is oblique Corner degree according to process requirements adjusted design be≤90 °, then when upper module produce and process with lower module, each pair upper punch and Its corresponding sliding block coordinates, and workpiece raw material is bent into required angle, particularly≤90 °.
The structure due to being that gap coordinates between upper punch and circular hanging platform, if so actual demand, its angle can also 90 ° of bendings of > are designed as, now only need to change discharging backboard and stripper, be replaced with > of the hole slot angle for needed for 90 ° of plate.
Further, the upper punch includes first pair of upper punch and second pair of upper punch along workpiece raw material direction of feed, It is corresponding with first pair of upper punch position, the first sliding block is provided with concave template;With second pair of upper punch position It is corresponding, the second sliding block is provided with concave template.
First pair of upper punch and the first sliding block coordinate processing, and the side of workpiece two to being fed through carries out bending and adds Work;Second pair of upper punch and the second sliding block coordinate processing, and the workpiece base to being fed through can carry out Bending Processing, this Place's preferred pin needs bending workpieces technique twice to edge.
Further, the first low punch is additionally provided with the die shoe, before first low punch is arranged on the first sliding block Side, by setting the first low punch, can carry out punching processing to workpiece before bending.
Further, the second low punch is additionally provided with the die shoe, after second low punch is arranged on the second sliding block Side, second low punch will can coordinate to the termination after the bending of workpiece base by second pair of upper punch and the second sliding block Carry out bending again.
Beneficial effects of the present invention:The bending progressive die of the present invention, is hung by the circle for being secured to upper punch Platform carries out gap cooperation so that upper punch can flexibly swing along circular hanging platform central shaft, by by upper module with this on The hole groove wall angle on discharging backboard and stripper that drift coordinates is set to required angle, such as≤90 °, then by upper and lower Mould is processed, you can realize workpiece raw material bending, and 90 ° of side surface of workpiece angle=after bending;Further, according to Workpiece structure need Ask, low punch can be set before bending technique, realize workpiece punching, low punch is set after bending technique, realize workpiece bottom The bending again of Edge Bend follower head, so that yi word pattern workpiece raw material is by after bending progressive die processing, realizing approximate Rectangular-shape Workpiece structure, whole process is processed using full-automatic, and without secondary manual repair, for batch production type, enterprise has Good economic benefit.
