Abstract
The utility model provides a cold cut -out press of leaf spring blanking, includes punching handle, lock nut, drift, the die that punches a hole, lower mould base, punching die bottom plate, and the drift fastens on having the punching handle of spacing boss through lock nut, and the welding of lock nut side has the ring washer, and the explosion -proof snare of unloading of rubber is continuous through bolt and ring washer on lock nut, and it is spacing on the lower mould base that the die that punches a hole passes through the retainingf key, and the lower mould base passes through the locating pin to be fixed on the punching die bottom plate. The utility model discloses a cold cut -out press of leaf spring blanking adopts direct blanking and the structure of unloading, and convenient operation has improved production efficiency, has reduced flat spring's manufacturing cost, abundant utilization the explosion -proof decrement of unloading ring rubber of rubber, make the drift protect work in the explosion -proof circle of unloading of rubber always, improved the security performance of operation greatly, the drift is spacing with the local fluting adoption retainingf key of die simultaneously, the commonality of mould when carrying high pressure heater and being good at different passes.
Description
Technical field
This utility model relates to a kind of leaf spring blanking cold punching punch die.
Background technology
Fast development recently as Chinese Automobile Industry ', it also it is a rare opportunity to develop for automotive suspension industry, big to air spring system, little to the least flexible member, either system synthesis or single part, its effect is the most extremely important, the performance of spring and the comfortableness of automobile, safety and functional be closely-related, constantly accelerate also with step in line with international standards simultaneously, increasingly sharpening of the market competition, people it is becoming increasingly recognized that product quality, the importance of the development ability of cost and new product, and cold-punching mold manufacture is one of most basic key element in whole chain, cold-punching mold manufacturing technology has become the important symbol weighing a national manufacture level height, and determine the vivosphere of enterprise to a great extent.
Summary of the invention
The purpose of this utility model is just to provide a kind of reasonable in design, safe and reliable, and the leaf spring blanking cold punching punch die convenient, processing charges is low, production efficiency is high changed by drift and die.
Leaf spring blanking cold punching punch die of the present utility model, including die shank, locking nut, drift, punching concave die, die ring for fixing, lower mold base, perforating die base plate, it is characterized in that, drift is fastened on the die shank of limited location boss by locking nut, locking nut side is welded with ring washer, the explosion-proof discharging ring of rubber is enclosed within locking nut and is connected with ring washer by bolt, punching concave die is spacing on lower mold base by retainingf key, and lower mold base is fixed on perforating die base plate by alignment pin.
Leaf spring blanking cold punching punch die of the present utility model, during use, regulation drift and die gap, control the relative positional accuracy in the upper and lower mould course of processing, then the decrement of rubber explosion-proof discharging ring rubber is utilized, compress the leaf of spring being placed on die when upper mold is descending in advance, then carry out leaf spring upper punch and separate with the blanking of die, complete punching operation finally by rubber explosion-proof discharging ring discharging.
Leaf spring blanking cold punching punch die of the present utility model; major advantage is the structure using direct blanking with discharging; easy to operate; improve production efficiency; reduce the manufacturing cost of plate spring sheet; sufficiently make use of the decrement of rubber explosion-proof discharging ring rubber; make drift protect to work in the explosion-proof discharging ring of rubber always; substantially increase the security performance of operation; drift and die differential trench open use retainingf key spacing simultaneously; the versatility of mould when improving processing different shaped jet holes, and save the input of mould development and shorten the production cycle of product development.
