Sealing machine

Abstract

The invention relates to a sealing machine, comprising a rack, a controller, a spindle, a spindle driving mechanism and a clamping device used for clamping workpieces to be processed, wherein a mould of the clamping device and the spindle share the same axis and are close to the front end of the spindle. The sealing machine is characterized in that the front end of the spindle is fixedly provided with a cutter head, the rear end of the spindle is connected with the spindle driving mechanism; the cutter head is provided with a sealing cutter and a sealing cutter guide mechanism, the sealing cutter slides along the direction vertical to the axis of the spindle under the guide action of the sealing cutter guide mechanism so as to be close to or far away from the axis of the spindle; and a material moving device is arranged between the rack and the clamping device, and the material moving device drives the clamping device to slide along the axis of the spindle, thus the clamping device is close to or far away from the end face of the cutter head. When the sealing machine is in operation, the clamping device used for clamping the workpiece to be processed does not rotate, the sealing cutter arranged on the cutter head rotates around the circumference of the spindle and extrudes the end part of the workpiece to be processed along the direction vertical to the axis of the spindle, and finally a sealing wall which is vertical to the side wall of the workpiece to be processed and is consistent in thickness is formed, thus the sealing effect is good. Besides, the material moving device can realize automatic feeding and return of materials, the production efficiency is high, and the automation degree is high.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing machine for rotary extrusion sealing the end of a workpiece to be processed, such as a metal pipe. Background technique [0002] The existing sealing machine mainly includes a clamping device for clamping the metal pipe to be processed and a tool inclined on the main shaft. The mold of the clamping device and the main shaft share the same axis and are fixed on the front end of the main shaft. When working, the staff first sends the metal pipe to be processed into the clamping device and is clamped by it, and then the clamping device drives the metal pipe to be processed to rotate at a high speed. At this time, the tool on the spindle moves axially and gradually rotates at a high speed. The metal tube to be processed is approached and its end is sealed, and finally the staff will take out the sealed metal tube from the clamping device. It has the following defects: 1. The metal pipe ...

AI Technical Summary

Problems solved by technology

It has the following defects: 1. The metal pipe to be processed is driven to rotate by the clamping device, and the cutter is set obliquely, and can only move axially close to the metal pipe to be processed. Therefore, when sealing the end of the metal pipe, it is difficult to form a joint with the metal pipe The side wall is perpendicular to the sealing wall, and the thickness of the sealing wall also has the defect of uneven thickness, the sealing effect is poor, and the service life of the metal tube is affected

2. The clamping device cannot move forward and backward along the main shaft, and the conveyance or removal of the metal pipe to be processed can only be manually operated by the staff. The work intensity is high, the production efficiency is low, and the degree of automation is not high.

3. When the sealing machine is working, the metal pipe to be processed rotates at high speed, but the cutter does not rotate, so only short metal pipes can be sealed. For pipes exceeding a certain length, there will be violent shaking during high-speed rotation and it is difficult to To achieve sealing processing, there is a certain limit on the length of the pipe to be processed, the scope of application is limited, and it is inconvenient to use
