A kind of plate spring blanking machine
The present invention relates to a kind of leaf spring manufacturing equipment, specifically a kind of plate spring blanking machine.
At present, leaf spring blanking and punching be all vertical punch press, be respectively two procedures, namely first by a punch press and the shearing die be arranged on punch press, steel plate is cut off, be steel plate stamping centre bore by another punch press again, punch press adopts one-shot head and slide block structure form, need 4-6 name workman to carry out operation to produce, and the turnover of steel plate and material loading are wasted time and energy, the labour intensity of workman is large, inconvenient operation, energy consumption, expense is too high, production safety coefficient is higher, because need twice clamping steel plate, its location is difficult to ensure unanimously, thus the low qualified of product.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of plate spring blanking machine that can complete cut-out simultaneously and rush centre bore two procedures.
For solving the problems of the technologies described above, the plate spring blanking machine provided comprises support and is contained in the operating desk at support top, its design feature is that operating desk is equipped with gantry type frame, the crossbeam of gantry type frame be equipped with the bent axle driven by power set and driven the drive rod moved up and down by bent axle, upper bolster is slidably connected between 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, gangbar has the head of spherical crown shape, the bottom of drive rod is provided with inserts and the blind hole of shape adaptation for this head, upper bolster is equipped with from going to rear spaced blanking patrix and punch upper die, blanking counterdie corresponding with blanking patrix and punch upper die respectively and punching counterdie described operating desk be equipped with.
After adopting said structure, spring steel are placed on operating desk, startup power set order about drive rod and move downward, under the effect of blanking patrix and blanking counterdie, punch upper die and punching counterdie, blanking and punching are carried out to spring steel simultaneously, gangbar is provided with the head of spherical crown shape and the blind hole adapted with it is set on drive rod, strong downward driving can be carried out to gangbar, namely the conduction being conducive to pressure drives upper bolster to move up and down, gantry type frame be provided with the stability be beneficial to when upper bolster moves up and down.
In sum, the present invention can complete simultaneously cuts off and rush centre bore two procedures, and no longer need twice clamping spring steel, accurate positioning, qualification rate is high.
As improvement of the present invention, material supporting rack is equipped with at the rear portion of described operating desk, and material supporting rack is connected with location-plate.Can adopt this structure to steel plate cut blanking and accuracy one-time positioning is carried out in punching.
Described power set comprise the driving shaft be rotatably connected on support, and driving shaft is driven by motor power, and driving shaft is equipped with driving gear, bent axle are equipped with the driven gear engaged with driving gear.
As a further improvement on the present invention, the pressing rubber sleeve corresponding with blanking counterdie forward position is equipped with in the front side of described blanking patrix, the pressing rubber sleeve corresponding with blanking patrix rear positions is also equipped with at blanking counterdie rear portion, when blanking patrix and blanking counterdie cut blanking to steel plate, two that arrange flatten rubber sleeve and lay respectively at the position, front and back that steel plate cuts place, rubber sleeve has certain elasticity, plays the effect flattening and prevent anti-shake.
Improve further again as of the present invention, blanking fairlead blanking patrix is equipped with, the blanking lead be slidably connected in blanking fairlead blanking counterdie is equipped with, punching fairlead punch upper die is equipped with, the punching lead be slidably connected in punching fairlead punching counterdie is equipped with, lead and fairlead be provided with the alignment being beneficial to blanking and punching two mold.
Improve further again as of the present invention, the both sides, front and back of described punch upper die are all bolted with guide post, jacking block is equipped with in the bottom of guide post, between jacking block and punch upper die, spring is housed, when punching die carries out punching, two jacking blocks lay respectively at the position, front and back of punching place, play flatten and prevent tremble effect, improve the degree of accuracy of punching position, improve the qualification rate of product.
As a further improvement on the present invention, described gantry type frame is equipped with the stable oil cylinder be positioned at above blanking patrix, the piston rod stablizing oil cylinder is connected with upper bolster.When cutting blanking, this upper bolster cuts the stressed comparatively large of position, stablizes being provided with of oil cylinder and is beneficial to guarantee stress equalization, play the effect of balance upper bolster.
