Abstract
The utility model discloses a bending die for a contact stamping piece of a line protector. The bending die comprises a lower die plate, and is characterized in that a boss is arranged on the right side on the upper surface of the lower die plate; the upper end on the inner side wall of the boss is an arc-shaped surface; a groove connected with the boss is formed on the upper surface of the lower die plate on the inner side of the boss; a punch head is arranged above the lower die plate; a step matched with the inner side wall of the boss is arranged at the bottom end on the right side wall of the punch head; and a step matched with the left side wall of the groove is arranged at the bottom end on the left side wall of the punch head. The bending die has simple structure; and the punch piece after being bent has light weight, good rigidity, high strength, better surface quality, and smooth and aesthetically pleasing appearance. The bending die has higher dimensional precision; the dimensions of pieces bent through the same die are uniform and identical; the bending die has better interchangeability; and general assembly and use requirements can be met without further machining operation.
Description
Technical field
The utility model relates to the diel field of stamping parts, is specifically related to the Bending Mould of a kind of line protector contact 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 Bending Processing 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 Bending Processing 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, can punching press portal nest, projection etc.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 bending, 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 bending 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 the Bending Mould of a kind of line protector contact stamping parts, line protector contact stamping parts is carried out bending operation, for subsequent technique is prepared.
The technical solution of the utility model is as follows:
A kind of line protector contact stamping parts Bending Mould, include lower bolster, it is characterized in that: the right side of described lower bolster upper surface is provided with boss, and the upper end of the madial wall of described boss is an arcwall face, and the lower bolster upper surface of boss inboard is provided with the groove that links to each other with boss; The top of described lower bolster is provided with drift, and the bottom of the right side wall of described drift is provided with the step that is complementary with described boss madial wall, and the bottom of the left side wall of drift is provided with the step that the left side wall with described groove 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.
