Description
Technical field
The present invention relates to diel field, be specifically related to a kind of bending progressive die.
Background technology
The process of scientific technological advance represents, mechanical industry is the important carrier that science and technology turns materially productivity, and Mould design and manufacturing occupies very important status at machinery industry.At present, in the products such as electronics, automobile, motor, household electrical appliances and military project, the parts of 60%-80%, all will rely on mould molding.With the high accuracy that formed in mould product shows, high complexity, high uniformity and low consumption, be that other machining manufactures are incomparable, mould decides the quality of product, benefit and development ability to a great extent.
The simple bending technique of tradition is generally completed by bender, realized by the progressive die for multiple working procedure bending technique is then general, so can produce in batches, enhance productivity, reduce production cost, but further bending technique is studied again, on discovery existing market, bending mainly completes the obtuse angle bending that angle is greater than 90 degree, implement then very few for needs 90 degree of bending techniques or the bending technique that is less than 90 degree, often need secondary operations just can realize, add forming step, be unfavorable for that enterprise produces in batches.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention provides a kind of bending progressive die, this bending progressive die can realize bending angle≤90 ° bending technique, for batch production provides feasible scheme.
The present invention for the adopted technical scheme that solves the problem is: provide a kind of bending progressive die, comprise module and lower module, described upper module comprises stripper and is successively set on discharging backboard on the upside of stripper, spring, fixed head, fixing backing plate, upper bolster and top mold frame; Described lower module comprises concave template and is successively set on die backing plate, die shoe and the bottom seat pad on the downside of concave template; Described fixed head is provided with multipair upper punch, described often pair of upper punch adopts matched in clearance to be fixed on fixed head by circular hanging platform, described concave template is provided with slide block with corresponding position, often pair of upper punch position, outside workpiece raw material is along feeding between stripper and concave template, through upper and lower module punch forming, the slide block making the often pair of upper punch corresponding with it coordinates workpiece raw material bending and molding, make shaping after workplace vertical side angle=90 °.
Owing to being matched in clearance between upper punch and circular hanging platform, so upper punch then can swing along the central shaft of circular hanging platform, in other words, upper punch pendulum angle can≤90 °,
Respective design is carried out by hole slot on the discharging backboard that runs through upper punch and stripper, its hole slot border hypotenuse angle is made to be≤90 ° according to process requirements adjusted design, then when upper module and lower module production and processing, the slide block cooperation that often pair of upper punch is corresponding with it, workpiece raw material is bent into required angle, particularly≤90 °.
This structure is owing to being matched in clearance between upper punch and circular hanging platform, if so actual demand, its angle also can be designed as > 90 ° of bendings, now only need to change discharging backboard and stripper, be replaced with the plate that hole slot angle is required > 90 °.
Further, described upper punch comprises first pair of upper punch and second pair of upper punch along workpiece raw material direction of feed, corresponding with described first pair of upper punch position, and concave template is provided with the first slide block; Corresponding with described second pair of upper punch position, concave template is provided with the second slide block.
Described first pair of upper punch coordinates with the first slide block to be processed, and carries out Bending Processing to the workpiece dual-side of feeding process; Described second pair of upper punch coordinates with the second slide block to be processed, and can carry out Bending Processing to the workpiece base of feeding process, preferred pin needs twice bending workpieces technique to edge herein.
Further, described die shoe is also provided with the first low punch, described first low punch is arranged on the first slide block front, by arranging the first low punch, can carry out punching processing to workpiece before bending.
Further, described die shoe is also provided with the second low punch, described second low punch is arranged on the second slide block rear, described second low punch, the termination after to the bending of workpiece base can be coordinated to carry out bending again by through second pair of upper punch with the second slide block.
Beneficial effect of the present invention: the bending progressive die of the present invention, by upper punch and its fixing circular hanging platform are carried out matched in clearance, upper punch can be swung flexibly along circular hanging platform central shaft, by the hole groove wall angle on the discharging backboard coordinated with this upper punch in upper module and stripper is set to required angle, such as≤90 °, then through upper and lower Mould Machining, the bending of workpiece raw material can be realized, and side surface of workpiece angle=90 ° after bending; Further, according to Workpiece structure demand, low punch can be set before bending technique, realize workpiece punching, low punch is set after bending technique, realize the bending again of workpiece base bending follower head, thus make yi word pattern workpiece raw material after the processing of this bending progressive die, realize approximate rectangular-shaped Workpiece structure, the full-automatic processing of omnidistance employing, without the need to secondary manual repair, for batch production type enterprise, there is good economic benefit.
