Description

A kind of essence is cut the mould of deburring

Technical field

The utility model belongs to the machining equipment field, relates to the mould that a kind of essence is cut deburring, and particularly a kind of essence that is used for auto brake tendon baffle is cut the mould of deburring.

Background technology

The shoe brake of automobile axle is used to the brake tendon baffle that leads, locate when installing, be to adopt by traditional technology: blanking-blanking-punching-flatten-mill limit-flash removed reaches product figure requirement.Although adopt two assembled end of horizontal milling machine end mill brake tendon baffle, but owing on milling machine, can only process an end face at every turn, now to process every product of two end faces and all will carry out the clamping location No. 2 times, and all there is the deviation on the location during each clamping, the uniformity of workpiece is difficult to guarantee that the guiding angle of both ends of the surface is difficult to stablize; The symmetry of both ends of the surface is difficult to reach requirement; The roughness Ra value of both ends of the surface is difficult to guarantee that therefore, there is risk in the quality of product always.And use the fine-edge blanking essence to cut deburring, and can make product add the accurate positioning in man-hour, like this by designing a kind of mould that the fine-edge blanking essence is cut deburring that can satisfy, guarantee just to seem very necessary by assembled end uniform quality, stable.

Summary of the invention

The purpose of this utility model provides a kind of takes the locate mode of " plane and two pits " one-time positioning, and its location benchmark essence consistent with the Element Design benchmark cut the mould of deburring.

The purpose of this utility model is achieved in that it comprises die shank, cope match-plate pattern, upper die plate, guide pin bushing, upper mould fixed plate, essence is cut punch, alignment pin, essence is cut die, guide pillar, counterdie fixed head, counterdie backing plate, lower bolster, mould is divided into the first half of mould and the latter half of mould, and the first half structure of mould is that essence is cut punch and is connected with upper mould fixed plate by bolt, and upper mould fixed plate is connected with upper die plate by bolt and alignment pin, upper die plate is connected with cope match-plate pattern by bolt and alignment pin, and die shank is connected with cope match-plate pattern respectively with guide pin bushing; The latter half structure of mould is: alignment pin is connected with the smart locating hole of cutting die, essence is cut die and is connected with the counterdie fixed head, the counterdie fixed head is connected with the counterdie backing plate by bolt and alignment pin, the counterdie backing plate is connected with lower bolster by bolt and alignment pin, guide pillar is connected with lower bolster, when assembled the upper and lower part of mould, essence was cut punch and is cut the single face gap of die in the 0.01-0.02mm scope with smart.

Location of the present utility model benchmark is consistent with the Element Design benchmark, has well eliminated the error that produces because of multiple clamping, not only can guarantee uniformity, the stability of slab spare workpiece both ends of the surface quality, and can strengthen production capacity, reduces production costs.
