An oil cylinder fixed on a frame drives an upper die to longitudinally move along a guide column; an upper die inclined block is fixed at the lower part of the upper die; the inclined plane of the upper die inclined block is pressed on the inclined planes of lower die inclined blocks; the two lower die inclined blocks slide along guide rails fixed on a lower die bottom board; the lower die bottom board is fixed on the frame; an air cylinder drives a casting die plate to longitudinally move; an extrusion die is fixed on the lower die bottom board; a workpiece placement groove is arranged on the extrusion die; a workpiece is clamped in the workpiece placement groove; punching pins are fixed on the lower die inclined blocks; the punching pins arranged at the two ends are simultaneously inserted into the square bottom hole of the workpiece to perform punching; a workpiece clamp clamps the workpiece; an upper die positioning column and a lower die positioning column share one axis and are respectively fixed on the upper die and the lower die bottom board; and when the workpiece is clamped, the upper die positioning column is in contact with the lower die positioning column. The double-headed square hole machine has the advantages of high production efficiency, convenient operation, good concentricity and non-deforming axial surface.

Description

Double end square hole machine

Technical field

The utility model relates to the square hole extrusion equipment technical field of a class, in machining, and square hole in the difformity of axial workpiece two ends, the plant equipment that extrusion process simultaneously is shaped.

Background technology

At present; the axle class the square hole extrusion process time; be to be shaped with the vertical fashion of extrusion of single head; processing method: processing earlier one is hole, property extruding four directions for the first time; hole, disposable extruding four directions, reprocessing other end; its weak point is: 1, adding man-hour, the axle surface of the axle of square hole does not have protective device in the two end bands, is easy to generate a superficial expansion.2, to the punching press of axle not towards the pin stopping means, easily axle is produced excessive stamping press and makes the axle total length shorten towards pin like this.3, divide secondary that the axle of square hole in the two end bands is carried out punching press, easily cause two square hole concentricity instability, the degree of depth is also unstable, can't satisfy the quality inspection requirement, and produces the many phenomenons of scrap.4, it is low to divide secondary that the axle of square hole in the two end bands is carried out stamping production efficiency.

The utility model content

The utility model purpose is in order to solve hole, square hole single head vertical extrusion molding four directions in the difformity of existing axial workpiece two ends, meeting produces a lot of defectives---and the axle areal deformation is big, two ends square hole concentricity instability, inconvenient operation, efficient is low, and the double end square hole machine that provides double end to push cubic hole simultaneously, its production efficiency height, easy to operate, good concentricity, the axle surface can not be out of shape.

Technology solution of the present utility model is as follows:

Double end square hole machine, the hydraulic oil cylinder driving patrix that is fixed on the frame moves up and down along guide pillar; The bottom of patrix is fixed with the patrix skewback, the inclined-plane of patrix skewback is pressed on the inclined-plane of counterdie skewback, two counterdie skewbacks slide along the guide rail that is fixed on down on the baffle plate, following baffle plate is fixed on the frame, air cylinder driven casting die plate moves up and down, extrusion die is fixed on down on the baffle plate, clamping workpiece on the standing groove of extrusion die, be fixed with towards pin on the counterdie skewback, two ends are inserted simultaneously towards pin in the bottom outlet of workpiece square hole and are carried out punching press, the work piece holder clamping work pieces, patrix reference column and counterdie reference column coaxial line are separately fixed on the upper die and lower die base plate.When Work-sheet pressing reference column with contact.

Described counterdie skewback is set on the patrix Angle Pin, and the patrix Angle Pin is fixed on the patrix.

Described work piece holder is by the anchor clamps base plate, the anchor clamps stand, and the anchor clamps handle, screw is formed, and is fixed with clamping fixture seat on the anchor clamps base plate, and the front end of anchor clamps handle is fixed with Workpiece clamping head, and screw is screwed onto on the Workpiece clamping head, the front end workpiece pressing of screw.

The beneficial effects of the utility model are:

1, adding man-hour, workpiece i.e. two ends of the axle of the interior square hole of two end bands is crushed between standing groove and casting die plate, and during punching press, workpiece can not produce expansion.

2, the degree of depth so the degree of depth is constant, can not make the axle total length shorten owing to be subjected to the position limitation protection of reference column because of axle being produced excessive stamping press.

3, axle to be processed is fixed in the extrusion die and is stamped two square hole concentricity height simultaneously.

4, the utility model once just can be finished the interior square hole punching press action to axle two ends, compares with the punching press of prior art secondary, has improved production efficiency greatly, has reduced production cost.

The specific embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See Fig. 1～7, double end square hole machine, the oil cylinder 2 driving patrixes 3 that are fixed on the frame 1 move up and down along guide pillar 4; The bottom of patrix 3 is fixed with patrix skewback 5, the inclined-plane of patrix skewback 5 is pressed on the inclined-plane 61 of counterdie skewback 6, two counterdie skewbacks 6 slide along the guide rail 8 that is fixed on down on the baffle plate 7, following baffle plate 7 is fixed on the frame 1, cylinder 9 drives casting die plate 10 and moves up and down, extrusion die 11 is fixed on down on the baffle plate 7, form workpiece 12 end standing grooves 111 on the extrusion die 11, be fixed with on the counterdie skewback 6 towards pin 13, insert in the square hole 121 of workpiece 12 towards pin 13, work piece holder 14 clamping work pieces 12, patrix reference column 16 and counterdie reference column 17 coaxial being separately fixed on patrix 1 and the following baffle plate 7.
