Description

Technical Field

[0001] The utility model relates to the technical field of submerged arc welding, in particular to an automatic cleaning device for submerged arc welding slag. Background Art

[0002] Submerged arc welding (SAW) is a highly efficient welding method suitable for welding medium and thick plate seams. It boasts high welding efficiency, aesthetically pleasing results, and stable weld quality, making it widely used in industries such as pressure vessels, engineering machinery, and steel structures. With the advancement of automation technology, automated SAW equipment has become increasingly popular in these industries, significantly improving production efficiency and product quality. However, slag removal has long been a challenge during SAW production, requiring manual cleaning, which has hindered the automation level of SAW production.

[0003] For example, the patent with announcement number CN207593022U discloses an automated submerged arc welding equipment based on vision and laser tracking. Although this utility model integrates automatic detection, identification, tracking, control and information transmission, improving the quality and efficiency of automatic welding, it still uses manual cleaning of welding slag. Utility Model Content

[0004] In view of the above problems in the prior art, the utility model provides an automatic cleaning device for submerged arc welding slag, which solves the problem that the existing automatic submerged arc welding equipment cannot clean the welding slag.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] Provided is an automatic cleaning device for submerged arc welding slag, which includes a mounting bracket fixed on automatic submerged arc welding equipment, with a cleaning component and a recovery component fixed on the mounting bracket; the cleaning component includes a cylinder fixed on the mounting bracket, the cylinder is electrically connected to a host computer and communicated with a pneumatic circuit, and a knocking piece for knocking off and crushing the welding slag is fixed on the pneumatic rod of the cylinder; the recovery component includes a negative pressure pipe fixed on the mounting bracket, the discharge port of the negative pressure pipe is communicated with a recoverer, the recoverer is communicated with the negative pressure air circuit, and the feed port of the negative pressure pipe is arranged toward the knocking piece.

[0007] In this solution, during the welding operation of the automatic submerged arc welding equipment, the cylinder drives the striking piece to synchronously knock the welding slag into fragments. The broken welding slag is sucked into the recovery device for unified recovery through the negative pressure effect of the negative pressure pipe, which reduces the labor intensity of the operating workers, liberates manual labor, realizes the fully automatic welding process, and improves the degree of automation of the automatic submerged arc welding equipment.

[0008] Furthermore, the cylinder is vertically fixed to the mounting bracket, and the pneumatic rod passes through the through hole of the mounting bracket and is fixedly connected to the striking member. The vertical arrangement of the cylinder enables the striking member to reciprocate vertically, which can act more directly on the welding part and improve the striking efficiency.

[0009] Furthermore, the pneumatic rod is fixedly connected to a slide seat on a vertical slide rail, which is in turn fixedly connected to the striking member. The vertical slide rail is disposed on the bottom end of the mounting bracket. The vertical slide rail ensures that the pneumatic rod drives the striking member in a more stable linear motion, thereby improving the stability of the cleaning effect and preventing incomplete cleaning caused by the striking member being misaligned.

[0010] Furthermore, a reinforcing rib is provided between the mounting bracket and the vertical slide rail. The design of the reinforcing rib effectively increases the connection strength between the mounting bracket and the slide rail, thereby improving the structural stability of the entire device.

[0011] Furthermore, a U-shaped seat is provided on the free end of the gas pressure rod, and the top of the slide seat is inserted into the U-shaped seat and connected to the U-shaped seat bolt. The U-shaped seat and bolt connection method make the connection between the gas pressure rod and the slide seat more firm and reliable.

[0012] Furthermore, an inverted L-shaped plate is fixed to the end surface of the slide, with the horizontal plate of the inverted L-shaped plate arranged horizontally, and multiple bolt holes for engaging with fixing bolts are provided through the end surface of the vertical plate of the inverted L-shaped plate. The top of the striking member is inserted into the gap between the vertical plate and the slide and abuts against the horizontal plate, and the threaded ends of the multiple fixing bolts respectively pass through the multiple bolt holes and abut against the striking member. The provision of the inverted L-shaped plate facilitates positioning the installation position of the striking member.

[0013] Furthermore, the striking member includes a fixed block and a striking block. The upper portion of the fixed block is a rectangular plate fixed to the slide, and the lower portion of the fixed block is an inverted isosceles trapezoidal plate, the bottom of which is fixedly connected to the striking block. The inverted isosceles trapezoidal plate reduces the size of the fixed block while ensuring that the striking force is more concentrated.

[0014] Furthermore, the striking block is in the shape of a rectangular parallelepiped, with a connecting U-shaped groove on the top of the striking block, into which the bottom of the inverted isosceles trapezoidal plate is inserted and bolted to both sides of the connecting U-shaped groove. The provision of the connecting U-shaped groove facilitates the installation of the striking block.

[0015] Furthermore, a first U-shaped groove and a second U-shaped groove are provided on the bottom of the knocking block. The first U-shaped groove and the second U-shaped groove can help to better concentrate the knocking force of the knocking block and improve the knocking effect of the knocking block.

[0016] Furthermore, a side plate is provided on the side of the mounting bracket away from the automatic submerged arc welding equipment, and the negative pressure pipe is fixed on the side plate.

[0017] The utility model discloses an automatic cleaning device for submerged arc welding slag, which has the following beneficial effects:

[0018] The utility model discloses that during the welding operation of the automatic submerged arc welding equipment, the cylinder drives the striking piece to synchronously strike the welding slag into fragments, and the crushed welding slag is sucked into the recovery device for unified recovery through the negative pressure effect of the negative pressure pipe, thereby reducing the labor intensity of the operating workers, realizing a fully automatic welding process, and improving the automation level of the automatic submerged arc welding equipment.

The inlet of the negative pressure pipe 4 is set toward the striking member 3.

[0026] In this embodiment, the host computer can be a PLC or controller in the automatic submerged arc welding equipment 6. The air pressure circuit and the negative pressure air circuit are existing technologies respectively provided with an air pump and a negative pressure fan. The automatic submerged arc welding equipment 6 is existing technology. This embodiment no longer elaborates on the specific working principles and connection relationships of the air pressure circuit, the negative pressure air circuit and the automatic submerged arc welding equipment 6.

The vertical arrangement of the cylinder 2 enables the striking piece 3 to reciprocate vertically, which can act more directly on the welding part and improve the striking efficiency.

[0028] As a further solution of this embodiment, in order to ensure that the pneumatic rod 21 drives the knocking member 3 to move smoothly in a straight line, it is possible to avoid incomplete cleaning caused by the knocking member 3 being offset. Figure 1 and Figure 2 The pneumatic rod 21 is fixedly connected to the slide 51 on the vertical slide rail 5, the slide 51 is fixedly connected to the knocking member 3, the vertical slide rail 5 is arranged on the bottom end of the mounting bracket 1, and a reinforcing rib 12 is provided between the mounting bracket 1 and the vertical slide rail 5.
