An enamel liner jacket necking device

Abstract

A necking device for a clamping sleeve of an enamel tank comprises a base sliding mechanism, a rotating pressure roller feeding mechanism and a tank fixing and clamping mechanism, wherein the base sliding mechanism comprises a base; a horizontal guide rail is arranged on the upper surface of the base, and guide rail sliding blocks are arranged on the upper surface of the horizontal guide rail; the rotating pressure roller feeding mechanism comprises two box bodies which are symmetrically arranged at the left and right parts of the upper surface of the base; box body moving motors are mounted at two ends of the upper surface of the base; a hollow main shaft is mounted in the middle of each box body through a bearing; a gear motor is arranged at the upper part of each box body; one end of each hollow main shaft is fixedly connected with a rotating frame while the other end of each hollow main shaft is equipped with a connector tightening-releasing motor through a flange plate; the tank fixing and clamping mechanism comprises a material supporting cylinder; a material supporting plate is arranged on the upper surface of the material supporting cylinder; clamping sleeve clamping cylinders are arranged at two sides of a tank; a tank opening positioning shaft and a tank bottom positioning shaft are arranged in the middle position of the outer side of each rotating frame. The necking device has the beneficial effects that the clamping sleeve can be necked directly while sleeving the tank, thus two ends of the clamping sleeve can be tightly combined with the tank, and the welding quality is stable.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to an enamel liner jacket necking device. Background technique [0002] The solar water heater enamel liner is composed of a liner and a jacket. Because the diameter of the liner is small and the diameter of the jacket is large, the diameter of both ends of the jacket must be reduced to make the two ends of the jacket tightly bonded to the surface of the liner. The smaller the gap, the better, which is conducive to the welding of the inner tank and the jacket. The traditional shrinking method of the jacket is to shrink the jacket first and then install the inner tank. Due to the deviation of the roundness of the inner tank and the jacket, it is easy to form a missing weld after welding. , Undercut and other welding defects. Contents of the invention [0003] The object of the present invention is to address the above existing deficiencies, and to provide a...
