Welding method and device of frame support rings of bag type dust collector

Abstract

The invention relates to a welding method and a device of frame support rings of a bag type dust collector. After longitudinal steel wires are straightened, the steel wires are inserted into welding equipment according to the number of frame longitudinal steel wires; support rings are put in to perform the spot welding connection with the longitudinal steel wires; and the radial expansion force is applied to the support rings before the welding, so that all the welding points of the support rings and the multiple longitudinal ribs are fully contacted. Compared with the prior art, the welding method and device can prevent the pseudo soldering phenomenon of synchronous welding of multiple points caused by the size errors of the support rings and devices for supporting the support rings.

Description

technical field [0001] The invention relates to a frame of a bag type dust collector, in particular to a welding method and device for a support ring of the frame of a bag type dust collector. Background technique [0002] The bag filter frame is mainly used in the bag filter in the field of atmospheric environmental protection, and is an important part of bag filter and dust removal. [0003] The traditional processing method is: after the longitudinal steel wires are straightened, the steel wires are inserted into the welding equipment according to the number of longitudinal steel wires of the frame, put into the support rings, and the longitudinal steel wires are connected with the support rings by spot welding. The welding equipment is a traditional bag cage welding machine, such as figure 1 As shown, it includes a longitudinal wire guide tube 1, a longitudinal wire guide plate 2, a longitudinal wire guide plate fixing seat 3, an integrated central motor fixing rod 4, a...

Problems solved by technology

This one-piece central electrode device has the following advantages: easy processing and easy installation; the price of a single piece of material is relatively cheap; the structure of the whole device is simple, etc., but the electrodes are easy to wear and tear, and about 2,000 bag cages need to be replaced; Depending on the cage specification, there are many specifications, even if the diameter difference is 1mm, it cannot be used; the gap between the outer circle of the electrode and the support ring is high, and the welding is not good if it is too loose, and it is not easy to place the support ring if it is too tight

[0004] Moreover, since the frame is a slender multi-solder structure, its support ring and multiple longitudinal ribs need to be welded at the same time. If the size deviation is large, it will cause false welding, which will eventually cause damage to the filter bag of the dust collector and failure of the dust collector. The whole system will take a huge toll
