Abstract

The invention discloses a wheel punching and extruding compound punch, which has an integrated structure, and is characterized in that: the upper end of a punch body is provided with an installation shoulder; the punch is arranged on the lower part of the punch body; and the upper part of the punch is provided with an inverted pyramid. Through the setting, the wheel punching and extruding compound punch is arranged on an upper punch of a punching machine through the installation shoulder, and the periphery of a bolt hole is extruded and chamfered by using the inverted pyramid while the punch is used for punching a wheel bolt hole during punching of a wheel, so that the periphery of the bolt hole becomes rounded and smooth, burrs are eliminated, and the position degree of the bolt hole is reduced.

Description

Wheel punching extruding compound punch
Technical field
The present invention relates to a kind of wheel die and push compound punch with punching.
Background technology
The bolt hole punching technology of the inner tube-free wheel spoke of China wheel shop comprises punching and extruding two steps of tapering at present; Promptly cause the position degree in wheel bolt hole bad easily; Influence production efficiency again, and be prone on screw, extrude burr, during the main engine plants fit a tyres; Burr is prone to incised wound and operator, causes unnecessary injury.
Summary of the invention
The purpose of this invention is to provide wheel punching extruding compound punch a kind of simple in structure, easy to use.
To achieve these goals, the present invention is an integral structure, is provided with in the upper end of punch body shoulder is installed, and drift is located at the bottom of punch body, is provided with the chamfering awl on drift top.
Through above setting, the present invention through being installed, shoulder is installed on the upper punch of punch press, when the wheel punching; Drift is to the punching of wheel bolt hole the time, and the chamfering awl is to pushing chamfering around the bolt hole, make bolt hole around mellow and full smooth; No burr diminishes bolt hole position degree.The present invention can reduce operator's labour intensity, can reduce personnel and mould again and be equipped with, and has reduced cost.
Description of drawings
Combine this figure that invention is further described at present.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, punch body, 2, shoulder is installed, 3, drift, 4, the chamfering awl.
The specific embodiment
As shown in Figure 1, the present invention is an integral structure, is provided with in the upper end of punch body 1 shoulder 2 is installed, and drift 3 is located at the bottom of punch body 1, is provided with chamfering awl 4 on drift 3 tops.Through above setting, the present invention through being installed, shoulder 2 is installed on the upper punch of punch press, when the wheel punching; In the time of 3 pairs of wheel bolt holes of drift punchings, push chamfering around 4 pairs of bolts hole of chamfering awl, make bolt hole around mellow and full smooth; No burr diminishes bolt hole position degree.
