Abstract
The utility model discloses a hole perforating needle of a copper tube extruding machine, which comprises a needle body, wherein one end of the needle body is provided with a connecting element, and the needle body is arranged on a horizontal punching rod of the cupper tube extruding machine through the connecting element. One end of the needle body of the hole perforating needle of the utility model is provided with the connecting element, the needle body is arranged on the horizontal punching rod of the copper tube extruding machine through the connecting element, the connecting element is not needed to be dismounted when the needle body needs to be replaced, only the needle body needs to be dismounted, and the replacement is convenient.
Description
Technical field
The utility model relates to copper pipe manufacturing technology field, relates in particular to a kind of pecker of copper pipe extruder.
Background technology
The existing copper pipe processing technique generally comprises operations such as the heating of copper base, hot extrusion, cutting, cold extrusion and post processing, wherein this class big machinery of extruder is generally adopted in hot extrusion, when selecting for use the center not have the copper base of through hole, need be in the central hole of copper base, and then push.Existing extruder generally comprises frame, the horizontal jumper bar of hydraulic oil cylinder driving, horizontal jumper bar top is provided with telescopic pecker, since between pecker and the horizontal jumper bar by being threaded, after long-time the use, complete close-fitting between pecker and the horizontal jumper bar often can't dismounting and change, influences manufacturing schedule.
Summary of the invention
The utility model provides a kind of pecker of copper pipe extruder, has solved existing pecker and has been not easy to the problem dismantling and change.
A kind of pecker of copper pipe extruder comprises needle body, and described needle body one end is provided with connector, and needle body is installed on the horizontal jumper bar of copper pipe extruder by this connector.
The hand dismounting is convenient to make, installs and is used to described needle body with the connector interference fit or by being threaded.
Described needle body is 5～8: 1 with the length ratio of connector, guarantees the intensity of connector.
Needle body one end of the utility model pecker is provided with connector, is installed in by this connector on the horizontal jumper bar of copper pipe extruder, and when needs were changed needle body, need not only needed the dismounting needle body with the connector dismounting, and it is convenient to change.
Description of drawings
Fig. 1 is the structural representation of existing pecker;
Fig. 2 is the structural representation of the utility model pecker.
The specific embodiment
As shown in Figure 2, a kind of pecker of copper pipe extruder, connector 2 by needle body 1 and needle body 1 one ends is formed, needle body 1 one ends are provided with one and are with externally threaded connecting rod, and an end of connector 2 is provided with the tapped cavity 21 that cooperates with connecting rod, they are combined just constituted pecker, also connector 2 and needle body 1 can other connected modes certainly, as interference fit etc.
The length ratio of needle body 1 and connector 2 is 6: 1, can certainly select other ratio for use, generally selects 5～8: 1 for use.The other end of connector 2 is provided with one equally and is with externally threaded connecting rod, and this connecting rod can cooperate with the horizontal jumper bar top cavity of copper pipe extruder, after the connection, has promptly finished the installation of pecker.
When after pecker repeatedly uses, maybe needing to change size, just needle body 1 can be separated from connector 2, be changed very convenient.
