Abstract
The utility model discloses a punching die for wiring terminal stamping parts of a low-voltage electrical apparatus, which comprises a lower die plate, and is characterized in that: a cylindrical die cavity is formed on the lower die plate, and a cylindrical punch is arranged above the lower die plate. The punching die has a simple structure, and the punched stamping parts have light weight, high rigidity, strength and surface quality and smooth and attractive appearance; and the punching die has high dimensional accuracy, and the parts punched on the same die have uniform size and high interchangeability, and can meet the common assembling and using requirements without being machined further.
Description
Technical field
The utility model relates to the diel field of stamping parts, is specifically related to a kind of low-voltage electrical apparatus wiring terminal stamping parts punching die.
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 low-voltage electrical apparatus wiring terminal stamping parts punching die, low-voltage electrical apparatus wiring terminal stamping parts is carried out punching, for subsequent technique is prepared.
The technical solution of the utility model is as follows:
A kind of low-voltage electrical apparatus wiring terminal stamping parts punching die includes lower bolster, and it is characterized in that: described lower bolster is provided with the cylindricality die cavity, and described lower bolster top is provided with the cylindricality drift.
The beneficial effects of the utility model:
The utility model is simple in structure, and the stamping parts of going out 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.
