Description

Technical Field

[0001] The utility model belongs to the technical field of air cooler preparation, and in particular relates to a pipe box panel welding slag removing device. Background Art

[0002] In the preparation of air coolers, the two ends of the finned tubes are often connected to the panel of the tube box by welding. After welding, welding slag will appear on the panel. In order to carry out surface anti-corrosion treatment on the entire finned tube box and make the product look good, the welding slag on the panel needs to be removed.

[0003] The existing welding slag removal method mostly adopts grinding. For manual operation, the iron filings and dust generated during grinding can easily enter the mouth and nose of workers, and long-term contact with workers may affect their health. Some existing automatic grinding equipment uses multiple grinding discs set at the grinding end to move along the length direction of the panel to remove the welding slag. However, there are gaps between adjacent grinding discs, and the welding slag between the gaps is easy to leak. Moreover, the grinding disc can only move along the length direction of the pipe box panel, and the moving direction is single. Some firmly bonded welding slag is not easy to be cleaned, and manual secondary removal is also required. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a pipe box panel welding slag removing device, which can not only move along the length direction of the pipe box panel during grinding and cleaning, but also move up and down along the height direction of the panel, so that the welding slag can be removed more thoroughly without the need for manual secondary operation, and the efficiency is high.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A pipe box panel welding slag removal device, comprising:

[0007] A conveying section, comprising a plurality of rows of rollers;

[0008] The grinding part includes a base, guide rails are respectively arranged on both sides of the top of the base, the top of the guide rails is a wave-shaped structure, a support is arranged between the two guide rails, the support can move along the length direction of the guide rails, and slide grooves are respectively arranged on both sides of the vertical direction of the support, a grinding piece seat plate is arranged in the slide groove, a plurality of grinding discs are arranged on one side of the grinding piece seat plate, and a roller is arranged at the bottom of the grinding piece seat plate, and the roller is slidably matched with the guide rails;

[0009] The positioning parts are provided with a plurality of groups, and at least one group is arranged at intervals on both sides of the grinding part.

[0010] Furthermore, a strip groove is provided on the top of the support, a screw rod is provided in the strip groove, a first motor is provided at one end of the screw rod, and the lower end of the support cooperates with the screw rod.

[0011] Furthermore, a plurality of connecting shafts are provided in the vertical direction along the other side of the grinding piece seat plate, a roller is provided at one end of the connecting shaft, the cross section of the slide groove is a T-shaped structure, and the roller is slidably matched with the horizontal part of the slide groove.

[0012] Furthermore, the positioning part includes a strip seat with a concave cross-section. A bidirectional screw rod is arranged inside the strip seat. A second motor is arranged at one end of the bidirectional screw rod. A group of baffles are arranged inside the strip seat, and the baffles respectively cooperate with the two threaded sections of the bidirectional screw rod.

[0013] Furthermore, one side of the two baffles facing each other is covered with a polyurethane pad, and a plurality of protrusions are provided on the pad.

[0014] The beneficial effects of the utility model are:

[0015] 1. Move the grinding part along the length direction of the pipe box panel to be cleaned, and stagger the grinding discs to avoid gaps between adjacent grinding discs, which may result in welding slag not being cleaned up, and improve cleaning efficiency;

[0016] 2. When the grinding part is cleaning welding slag, it can not only move along the length direction of the pipe box panel, but also move up and down along the height direction of the pipe box panel, so that the welding slag is subjected to force in multiple directions during cleaning, making it easier to clean;

[0017] 3. Multiple grinding discs are symmetrically arranged on both sides of the grinding part. When the upper fin tube box assembly moves to the front of the grinding part along the moving direction of the conveying part, the fin tube box assembly stops, and the grinding part can remove the welding slag from the tube box panel at the other end of the fin assembly. There is no need to transfer the grinding part, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
