Abstract

The utility model discloses a corner cutting and punching combined die for a spring piece, which relates to a corner cutting and punching die for a spring piece blank, and is designed mainly for solving the problem of complex corner cutting and punching machining process of a spring piece blank at present. The corner cutting and punching combined die comprises a lower die holder, a carrying plate and a positioning block, wherein a guide column and a lower knife fixing block with a lower knife are both arranged on the lower die holder; the lower knife is provided with edges on two sides; spacers are arranged below both female dies on the lower knife; the front and rear ends of a stripper plate on the lower knife fixing block are provided with openings; a positioning plate is arranged in front of the stripper plate; a guide sleeve, which is fixedly arranged on an upper die holder, is arranged on the guide column in a sleeved manner; an upper knife fixing block is arranged on the upper die holder; two upper knives are arranged on the two sides of the upper knife fixing block, respectively; the upper knife fixing block is provided with front and rear punch head fixing blocks; upper spacers are arranged in both the front and rear punch head fixing blocks; front and rear punch heads are arranged on the front and rear punch head fixing blocks, respectively; the upper die holder is provided with a die shank; a reverse block on the lower die holder is in zero-clearance fit with a reverse block on the upper die holder. The corner cutting and punching combined die has the advantage that the corner cutting and the punching of the spring piece blank can be simultaneously performed.

Description

Spring leaf corner cut punching assembling die

Technical field:

The utility model relates to a kind of mould that can simultaneously carry out corner cut and punching to the spring leaf blank after rolling.

Background technology:

When processing minicar is used spring leaf, will be in the front end both sides of spring leaf blank corner cut, and on spring leaf blank, go out straight hole and rivet hole, current processing method is first to use pressing equipment corner cut on angle cutting die, then at perforating die upper punch straight hole, and last punch rivet holes on another perforating die, shortcoming is to need equipment many, recruitment is many, and processing technology is loaded down with trivial details, and processing cost is high.

Summary of the invention:

Technical problem to be solved in the utility model be to provide a kind of can be simultaneously to the spring leaf blank corner cut after rolling with rush the spring leaf corner cut punching assembling die of straight hole and rivet hole.

Above-mentioned purpose is achieved in that it comprises die shoe, retainer plate is contained in the rear end of die shoe by bolt, on retainer plate, there is slotted hole, bolt on locating piece is contained in the slotted hole of retainer plate, on locating piece upper surface, there is boss, by adjusting the position of bolt in retainer plate slotted hole, can make locating piece move forward and backward in slotted hole, guide pillar is contained in the front end of die shoe, lower cutter fixed block is contained on die shoe by bolt, lower cutter fixed block is between guide pillar and retainer plate, lower cutter is contained on lower cutter fixed block, there is sword the left and right sides of lower cutter, on the cutter hub of lower cutter, there are two dies, there is pad the below of each die, the pad of die below, on lower cutter fixed block and die shoe, there is the blanking through hole being interconnected, stripper be buckled in lower cutter directly over, stripper is fixed on lower cutter fixed block, the front-end and back-end of stripper are all provided with the opening passing through for spring leaf blank, the place ahead of stripper is also provided with location-plate, guide pin bushing is sleeved on guide pillar, guide pin bushing is fixed on upper bolster, upper slitter fixed block is contained on upper bolster by bolt, two upper slitters are contained in respectively the both sides of upper slitter fixed block by bolt, two upper slitters lay respectively at two blades of lower cutter directly over, the blade of upper slitter is relative with the blade of lower cutter, front drift fixed block and back punching head fixed block are housed on upper slitter fixed block, in front drift fixed block and back punching head fixed block, there is Upper gasket, front drift is contained on front drift fixed block, back punching head is contained on back punching head fixed block, front drift and back punching head lay respectively at two dies on lower cutter cutter hub directly over, on upper bolster, have for the die shank being connected with press machine, also comprise two pairs of pieces of tossing about, the a pair of left and right sides that is fixed on die shoe wherein, another is to being fixed on the corresponding position of upper bolster, the piece gapless of tossing about of tossing about on piece and upper bolster on die shoe coordinates.

The course of work and advantage: the die shank in this device is connected with press machine, spring leaf blank front end after rolling is placed on the lower cutter of stripper below, according to the length adjustment locating piece of spring leaf blank, the front end of spring leaf blank is withstood on location-plate, rear end withstands on the boss of locating piece, press machine work drives upper bolster to move downward, when moving downward, upper bolster drive two drifts and upper slitter to move downward, can give spring leaf blank corner cut simultaneously and rush straight hole and rivet hole, advantage be can be simultaneously on an equipment to spring leaf blank corner cut with rush straight hole and rivet hole, equipment is few, recruitment is few, operating efficiency is high, reduced processing cost.
