Abstract
The invention discloses a kind of auto pump driving member through-hole device, including upper punching, shaping seat and steel ball；The upper end of the upper punching is fixedly mounted on the moved cross beam of hydraulic press, and shaping seat is mounted on the work top of hydraulic press and positioned at the underface of upper punching, and steel ball is nested in the processing hole of workpiece and the upper end of steel ball and the lower end of upper punching abut against.Since present invention punching hard alloy tungsten carbide steel ball that one was refined was pushed up by force with the endoporus for having small allowance after Vehicle Processing, used tool is simple, easy to operate, is easy to grasp.Improve endoporus circularity and hole wall surface roughness to the maximum extent.The present invention can also correct prismatic roundness and taper, greatly improve production efficiency.
Description
Technical field
The present invention relates to field of extrusion, more particularly to a kind of auto pump driving member through-hole device.
Background technology
Either top gem of a girdle-pendant hole or fraising is required for complicated fixture to be positioned, to ensure that the original geometric tolerance of product is unlikely
Too many in reducing, in addition careful clamping makes working efficiency too low, while cutter is that leptoprosopy contact causes the loss of cutter very big.
Sintered metal product steel ball cold breakdown extrusion process is a kind of effective ways of skin processing.Compared with top gem of a girdle-pendant hole, fraising, cold breakdown is squeezed
It presses process efficiency high, at low cost, endoporus can not only be corrected, reduce surface roughness value, and hole wall surface can be strengthened, increased tired
Labor service life and corrosion resistance do not influence the original geometric tolerance of product also.
Invention content
The purpose of the present invention is to provide a kind of high precision machining, auto pump driving member through-hole devices simple in structure.
By the mode of production of the approximation without fixture, production efficiency is greatly improved, it is complete to preserve the original geometric tolerance of product.
To achieve the above object, technical solution of the invention is：
The present invention is a kind of auto pump driving member through-hole device, including upper punching, shaping seat and steel ball；The upper end of the upper punching
It is fixedly mounted on the moved cross beam of hydraulic press, shaping seat is mounted on the work top of hydraulic press and is located at upper punching just
Lower section, steel ball is nested in the processing hole of workpiece and the upper end of steel ball and the lower end of upper punching abut against.
After using the above scheme, since the present invention hard alloy tungsten carbide steel ball that punching was refined one pushes up by force
It crosses with the endoporus for having small allowance after Vehicle Processing, used tool is simple, easy to operate, is easy to grasp.To the maximum extent
Improve endoporus circularity and hole wall surface roughness.The present invention can also correct prismatic roundness and taper, greatly improve production effect
Rate.
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
As shown in Figure 1, the present invention is a kind of auto pump driving member through-hole device, including upper punching 1, shaping seat 2 and steel ball
3。
The upper end of the upper punching 1 is fixedly mounted on the moved cross beam 101 of hydraulic press 10, and shaping seat 2 is mounted on oil
It presses on the work top of punching machine 10 and positioned at the underface of upper punching 1, steel ball 3 is nested in the processing hole 201 of workpiece 20 and steel ball 3
Upper end and it is upper punching 1 lower end abut against.
The operation principle of the present invention：
1st, workpiece 20 is mounted on the work top of hydraulic press 10；
2nd, steel ball 3 is nested with interior in the processing hole 201 of workpiece 20 and steel ball 3 upper end face and the lower end of upper punching 1；
3rd, the moved cross beam 101 of hydraulic press 10 moves down, and 1 is rushed in drive and is pushed, steel ball 3 is squeezed into workpiece by ejection steel ball 3
In 20 processing hole 201.
The emphasis of the present invention is that：The processing hole of workpiece is squeezed into using steel ball.
The above, only present pre-ferred embodiments, therefore the range implemented of the present invention cannot be limited with this, i.e., according to
The equivalent changes and modifications that scope of the present invention patent and description are made all should still belong to the model that patent of the present invention covers
In enclosing.
