Embodiment 1

[0047] combine figure 1 , figure 2 , image 3 , Figure 4 As shown, the embodiment of the present invention provides a template combination for on-line surfacing welding of a star gear tooth plate, including: an outer template 3, an inner template 4 and a positioning pin 5; the outer template 3 has two pieces, fixedly arranged on the star gear teeth On both sides of the plate 2, an arc-shaped curved surface is processed on the outer template 3, and the shape and size of the arc-shaped curved surface are the same as those of the star gear tooth plate 2. The outer sample plate 3 is used to compare the shape of the star gear tooth plate 2 during surfacing welding, that is, the outline formed by the two outer sample plates 3 is the outline of the tooth plate that is expected to be surfacing. The groove-shaped area formed between the surface of the plate is the area that needs to be filled by surfacing welding. When surfacing welding, the outer sample plate 3 can be observed in...

Embodiment 2

[0050] An online surfacing welding method for a star gear tooth plate provided by an embodiment of the present invention includes:

[0051] Step S1: Perform pre-welding treatment on the star gear plate of the sintering machine that needs to be repaired;

[0052] Step S2: According to the size of the star wheel tooth plate, one inner template and two outer templates are produced in Example 1;

[0053]Step S3: Fix the two outer templates on both sides of the star wheel tooth plate. In this embodiment, drill a mounting hole with a diameter of 21.8mm according to the position on the drawing, coincide with the original positioning hole on the star wheel tooth plate, and insert them together The positioning pin with a diameter of 21.6mm is positioned, and the rest of the outer sample plate is firmly fixed with the star wheel tooth plate. After the outer sample plate is installed, the working surface of the outer sample plate and the star wheel tooth plate forms a groove body to be ...

Abstract

The invention discloses a sample plate combination for online overlaying of a star wheel tooth plate. The sample plate combination for online overlaying of the star wheel tooth plate comprises outer sample plates and an inner sample plate, wherein the two outer sample plates are fixedly arranged on two sides of the star wheel tooth plate, and are used for comparing and molding when overlaying is carried out on the star wheel tooth plate; and the inner sampling plate is inserted into a tooth groove of the star wheel tooth plate, and is used for inspecting a tooth profile outline of the star wheel tooth plate before and after welding. The invention further discloses an online overlaying method of the star wheel tooth plate. According to the sample plate combination for online overlaying of the star wheel tooth plate, and the online overlaying method provided by the invention, the size restoration of the worn tooth plate can be realized without disassembling the star wheel tooth plate, the installation problem during a tooth plate disassembling and assembling process is avoided, and the overhaul time is saved.

Description

technical field [0001] The invention relates to the technical field of maintenance of sintering machine equipment, in particular to a combination of templates for on-line surfacing welding of star gear tooth plates and an online surfacing welding method. Background technique [0002] Such as figure 1 As shown, after the star wheel 1 at the head of the sintering machine or the tooth plate 2 of the star wheel at the tail are worn, the tooth shape has been worn from the original nearly involute teeth to straight teeth. The traditional way of repairing the star wheel tooth plate 2 is to replace the new star wheel tooth plate, or remove the star wheel tooth plate 2 and then process it offline. However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: both methods need to take down the old...
