Abstract
The invention discloses a bending die for a bimetallic support stamped part, comprising a lower template. The bending die is characterized in that the upper surface of the lower template is provided with multi-stage steps; a punch is arranged above the lower template; the lower surface of the lower template is provided with multi-stage steps which are matched with the multi-stage steps on the upper surface of the lower template; a gap exists between the lower template and the punch; and a stamped part to be bent is placed in the gap. The bending die has simple structure and the bent stamped part has light weight, good rigidity, high strength, good surface quality and smooth and beautiful appearances. The bending die has higher dimensional accuracy and the same module has uniform and identical dimension, thus having good interchangeability and being capable of meeting the general assembly and use requirements without further mechanical processing.
Description
Technical field
The present invention relates to the diel field of stamping parts, be specifically related to a kind of Bending Mould of bi-metal stent stamping parts.
Background technology
By punch press and mould sheet material, band, tubing and section bar etc. are applied external force, make it to produce plastic deformation or separation, thereby obtain the forming and machining method of the workpiece of required form and size, the workpiece that obtains is exactly a stamping parts.
Stamping parts is that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., makes it to produce plastic deformation or separation, thereby obtains the forming and machining method of the workpiece (stamping parts) of required form and size.Punching press and forging belong to plastic working (or claiming pressure processing) together, are collectively referred to as forging and pressing.The blank of punching press mainly is hot rolling and cold rolling steel plate and steel band.
Stamping parts is compared with foundry goods, forging, has thin, even, light, strong characteristics.Punching press can be made the workpiece that has reinforcement, rib, fluctuating or flange that additive method is difficult to make, to improve its rigidity.Because adopt precision die, workpiece accuracy can reach micron order, and repeatable accuracy height, specification unanimity, nest, boss etc. can punching press portal.Cold-stamped part is generally no longer through machining, or only needs a spot of machining.Heat-punch member precision and surface state are lower than cold-stamped part, but still are better than foundry goods, forging, and the machining amount is few.
Punching press is a production method efficiently, adopts compound die, especially multi-station progressive die, can finish multi-step forming processes on a forcing press, realizes by the uncoiling of band material, leveling, the stamping-out fully-automatic production to shaping, finishing.The production efficiency height, working condition is good, and production cost is low, and general per minute can be produced hundreds of.
Punching press is very big to the quality influence of presswork with the surface and the internal performance of plate, requires stamping material thickness accurately, evenly; Any surface finish, no spot, no scar, nothing scratch, no face crack etc.; Yield strength is even, does not have obvious directionality; The uniform elongation height; Yield tensile ratio is low; Work hardening is low.
The precision of mould and structure directly influence the shaping and the precision of stamping parts.Die manufacturing cost and life-span then are the key factors that influences stamping parts cost and quality.Mould design and manufacturing need the more time, and this has just prolonged the production time of new stamping parts.
The standardization of die holder, mould bases, guide and development simple die (for small lot batch manufacture), compound die, multi-station progressive die (for producing in a large number), and development quick die change device, can reduce punching production preparation amount and shorten time, can make to be applicable to minimizing punching production preparation amount and to shorten time, can make the advanced stamping technology that is applicable to production in enormous quantities reasonably be applied to the many variety production of small lot.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Bending Mould of bi-metal stent stamping parts, and the bi-metal stent stamping parts is carried out bending, for subsequent technique is prepared.
Technical scheme of the present invention is as follows:
A kind of Bending Mould of bi-metal stent stamping parts, include lower bolster, it is characterized in that: the upper surface of described lower bolster is provided with multistage step, and the top of described lower bolster is provided with drift, the lower surface of described drift is provided with multistage step, and is complementary with the multistage step of lower bolster upper surface; Gapped between described lower bolster and the drift, place the stamping parts that remains bending in the gap.
Beneficial effect of the present invention:
The present invention is simple in structure, and the stamping parts after the bending is in light weight, good rigidity, intensity height, have preferably surface quality, smooth in appearance attractive in appearance; The present invention has high dimension precision, and same module size uniformity has interchangeability preferably, does not need further machining can satisfy general assembly and use requirements.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of Bending Mould of bi-metal stent stamping parts includes lower bolster 1, the upper surface of lower bolster 1 is provided with multistage step 3, the top of lower bolster 1 is provided with drift 2, and the lower surface of drift 2 is provided with multistage step 4, and is complementary with the multistage step 3 of lower bolster 2 upper surfaces; Gapped between lower bolster 1 and the drift 2, place the curved stamping parts 5 that remains to be rolled in the gap.
