Description

A kind of leaf spring blanking machine

Technical field

The present invention relates to a kind of leaf spring manufacturing equipment, specifically is a kind of leaf spring blanking machine.

Background technology

At present, what leaf spring blanking and punching were used all is vertical punch press, is respectively two procedures; Promptly steel plate is cut off earlier through a punch press and the shearing die that is installed on the punch press, again through another punch press be steel plate towards centre bore, punch press adopts one-shot head and slide block structure form; Need 4-6 name workman to operate production, and the turnover of steel plate and material loading waste time and energy, working strength of workers is big; Inconvenient operation, energy consumption, expense are too high, and the production safety coefficient is higher; Because need twice clamping steel plate, its location is difficult to guarantee consistent, thereby the qualification rate of product is on the low side.

Summary of the invention

The technical problem that the present invention will solve provides a kind of can the completion simultaneously and cuts off and towards the leaf spring blanking machine of centre bore two procedures.

For solving the problems of the technologies described above; The leaf spring blanking machine that is provided comprises support and the operating desk that is contained in the support top; Its design feature is that gantry type frame is housed on the operating desk, and bent axle that is driven by power set and the drive rod that is moved up and down by the bent axle drive are housed on the crossbeam of gantry type frame, slidely connects upper bolster between the two vertical walls of gantry type frame; The vertical wall of front side is provided with feeding-passage; The top of upper bolster is fixed with gangbar, and gangbar has the head of spherical crown shape, and the bottom of drive rod is provided with and supplies the blind hole that this head inserts and shape adapts to; Be equipped with on the upper bolster from the blanking patrix and the punching patrix that go to the back to be provided with at interval, corresponding with blanking patrix and punching patrix respectively blanking counterdie and punching counterdie are housed on the said operating desk.

After adopting said structure; The spring steel are placed on the operating desk; The startup power set order about drive rod and move downward, and under the effect of blanking patrix and blanking counterdie, punching patrix and punching counterdie, the spring steel are carried out blanking and punching simultaneously; The blind hole that adapts with it is set at the head that is provided with the spherical crown shape on the gangbar with on drive rod; Can carry out strong downward driving to gangbar, the conduction that helps pressure promptly drives upper bolster and moves up and down, the stability when being provided with of gantry type frame is beneficial to upper bolster and moves up and down.

In sum, the present invention can accomplish cut-out simultaneously and towards the centre bore two procedures, no longer need twice clamping spring steel, accurate positioning, and qualification rate is high.

As improvement of the present invention, material supporting rack is equipped with at the rear portion of said operating desk, is connected with location-plate on the material supporting rack.Can adopt this structure to steel plate cut blanking and the accuracy one-time positioning is carried out in punching.

Said power set comprise the driving shaft that is rotatably connected on the support, and driving shaft is driven by motor power, and driving gear is housed on the driving shaft, and the driven gear with the driving gear engagement is housed on the bent axle.

As further improvement of the present invention; The pressing rubber sleeve corresponding with blanking counterdie forward position is equipped with in the front side of said blanking patrix; The pressing rubber sleeve corresponding with blanking patrix rear positions also is equipped with at blanking counterdie rear portion, and when blanking patrix and blanking counterdie cut blanking to steel plate, two of setting flattened rubber sleeves and lay respectively at the position, front and back that steel plate cuts the place; Rubber is with certain elasticity, plays the effect that flattens and prevent anti-shake.

Further improve again as of the present invention; The blanking fairlead is housed on the blanking patrix; The blanking lead that is slidingly connected in the blanking fairlead is housed on the blanking counterdie; The punching fairlead is housed on the punching patrix, the punching lead that is slidingly connected in the punching fairlead is housed on the punching counterdie, lead and fairlead be provided with the alignment that is beneficial to blanking and punching two molds.

Further improve as of the present invention, the both sides, front and back of said punching patrix all are bolted with guide post again, and jacking block is equipped with in the bottom of guide post; Between jacking block and the punching patrix spring is housed; When punching die carried out punching, two jacking blocks laid respectively at the position, front and back of punching place, played the effect that flattens and prevent to tremble; Improve the degree of accuracy of punching position, improved the qualification rate of product.

As further improvement of the present invention, the stable oil cylinder that is positioned at blanking patrix top is housed on the said gantry type frame, the piston rod of stablizing oil cylinder is connected with upper bolster.When cutting blanking, this upper bolster cuts the stressed bigger of position, stablizes being provided with of oil cylinder and is beneficial to the assurance stress equalization, plays the effect of balance upper bolster.
