Abstract
The utility model discloses a bending die for bimetallic bracket punching parts, which comprises a lower template, and is characterized in that: the right side wall of the lower template is provided with a tongue-shaped die cavity; a punch is arranged on the upper right of the lower template; and the lower end of the left side wall of the punch is provided with an arc-shaped surface matched with the outer wall of the die cavity on the right side wall of the lower template. The bending die has a simple structure; the bent punching parts have light weight, high rigidity, strength and surface quality and smooth and attractive appearance; the bending die has high dimensional accuracy; and the parts bent in the same die have uniform size and high interchangeability and can meet the common assembling and using requirements without being further machined.
Description
Technical field
The utility model relates to the diel field of stamping parts, is 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.
The utility model content
The technical problems to be solved in the utility model 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.
The technical solution of the utility model is as follows:
A kind of Bending Mould of bi-metal stent stamping parts, include lower bolster, it is characterized in that: the right side wall of described lower bolster is provided with the ligulate die cavity, the upper right side of described lower bolster is provided with drift, and the lower end of described drift left side wall is provided with the arcwall face that the die cavity outer wall with described lower bolster right side wall is complementary.
The beneficial effects of the utility model:
The utility model 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 utlity model has high dimension precision, 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 the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of Bending Mould of bi-metal stent stamping parts includes lower bolster 1, and the right side wall of lower bolster 1 is provided with ligulate die cavity 3, the upper right side of lower bolster 1 is provided with drift 2, and the lower end of drift 2 left side walls is provided with the arcwall face 4 that the outer wall with the die cavity 3 of lower bolster 1 right side wall is complementary.
Claims (1)
1. the Bending Mould of a bi-metal stent stamping parts, include lower bolster, it is characterized in that: the right side wall of described lower bolster is provided with the ligulate die cavity, the upper right side of described lower bolster is provided with drift, and the lower end of described drift left side wall is provided with the arcwall face that the die cavity outer wall with described lower bolster right side wall is complementary.
