Description
Technical field
The utility model relates to a kind of machinery processing apparatus, is specifically related to a kind of two elastic ejector device.
Background technology
Ejector is common structure in a mold, is all provided with ejector in many extrusion forming molds, and ejector is effective parts of workpiece discharging.
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the stamping-out of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.Cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab > 1.5mm) two kinds.For ejector, need the power utilizing extrusion die, carry out energy storage.The energy elasticity deformation of storage can be utilized to be ejected by workpiece when upper bolster rises.
Utility model content
The purpose of this utility model is to provide a kind of two elastic ejector device, adopts the structure improved, and can effectively complete the operation of head part by work in-process, meet the requirement of processing.
For achieving the above object, the technical solution of the utility model is: two elastic ejector device, comprise die shoe, the upper end of described die shoe doubles as die face, is provided with the cavity of hollow in described die shoe, runs through being provided with push rod in described die shoe, described push rod is arranged with the first rubber spring, described first rubber spring is arranged in cavity, and the top contact of described first rubber spring has an ejector that can slide along push rod, and die shoe is stretched out in the end of described ejector; Described lower push rod is also provided with the second rubber spring, and described second rubber spring is positioned at the below of die shoe, and described push rod is fixed with a top board, described top board is positioned at the bottom of the second rubber spring.
When adopting technique scheme, by being provided with the first rubber spring and the second rubber spring can produce deformation by work in-process respectively, wherein the first rubber spring acts on the ejector in die shoe, workpiece can be ejected from die shoe.And the second rubber spring acts on die shoe and on push rod, can play the effect of dual jacking.Structure of the present utility model is simple, and does not need the structure considering upper bolster, can use with the collocation of different moulds, versatility and reliability higher.
Further, described push rod is provided with the second hold-down nut, and described second hold-down nut is positioned at the below of top board.
Further, described push rod is provided with fixed head, and described fixed head is arranged in the below of cavity first rubber spring, and described push rod is also provided with first hold-down nut, described first hold-down nut is positioned at the below of fixed head.Above-mentioned setting, can regulate the position of rubber spring by the position brief introduction of adjustment hold-down nut.
Further, the width of described second rubber spring is greater than the width of the first rubber spring.
