Description

Technical Field

[0001] The utility model relates to the technical field of sword-grid slag removal for cutting machines, in particular to a sword-grid slag remover for cutting machines with replaceable scrapers. Background Art

[0002] The cutting machine sword grid is the serrated support bar on the cutting machine workbench. The liquefied metal residue generated when the cutting machine is working will flow onto the working platform, i.e. the sword grid. After long-term accumulation of these metal residues in multiple layers, they will adhere to the sword grid, seriously affecting the cutting effect of the laser machine. Therefore, it is usually necessary to use a cutting machine sword grid slag remover for slag removal. However, the existing cutting machine sword grid slag remover is not convenient for rapid disassembly and replacement of the scraper, which may cause the entire equipment to be scrapped due to damage to the scraper.

[0003] In order to solve the above problems, a cutting machine sword-grid slag remover with replaceable scrapers is proposed. Summary of the Invention

[0006] By clamping the scraper on the support plate, the scraper is initially limited, and by passing the four fastening bolts through the corresponding four first mounting holes, the scraper is fixed to the support plate, so that the scraper can be quickly installed. By removing the four fastening bolts, the scraper is no longer limited, and then the scraper is pulled with a greater force to separate it from the support plate, which facilitates the rapid disassembly and replacement of the scraper, and can avoid the situation where the entire equipment is scrapped due to local damage. By clamping the connecting pipe on the standard rod and then installing the extension rod on the standard rod, the length of the slag remover operating rod can be adjusted to adapt to different usage requirements. It is convenient for the operator to work on the ground and also for the operator to operate on the workbench. The coordinated arrangement of the left reinforcement plate, the right reinforcement plate and the tail reinforcement plate can improve the structural strength of the slag removal unit, making the slag removal unit more durable.

[0007] Preferably, a connecting tube is provided at one end of the standard rod away from the rotating shaft, an extension rod is fixedly connected to one end of the connecting tube away from the standard rod, and a handle is provided at one end of the extension rod away from the connecting tube. By clamping the connecting tube on the standard rod and then installing the extension rod on the standard rod, the length of the slag remover operating rod can be adjusted to adapt to different usage requirements.

[0008] Preferably, two second mounting holes are provided at the connection between the short handle and the standard rod, and a fixing bolt is provided between each of the two second mounting holes. Nuts are threaded on the bottom of the surfaces of the two fixing bolts. The standard rod is fixed to the short handle by inserting the two fixing bolts into the four second mounting holes and then tightening the nuts.

[0009] Preferably, a blade is provided in the middle of the scraper. The scraper is made of high-speed steel, which reduces manufacturing costs while ensuring sufficient wear resistance. A vertical surface is used at the blade to increase the strength of the blade.

[0010] Preferably, a left reinforcing plate and a right reinforcing plate are fixedly provided on both sides of the connection between the rotating shaft and the supporting plate, respectively. The structural strength of the slag removal unit can be improved by the provision of the left reinforcing plate and the right reinforcing plate.

[0011] Preferably, a tail reinforcement plate is fixedly provided between the short handle, the rotating shaft and the supporting plate, and the structural strength of the slag removal unit can be improved by providing the tail reinforcement plate.

[0012] Preferably, two first mounting holes are provided on both sides of the connection between the support plate and the scraper plate, and the scraper plate is fixed to the support plate by passing four fastening bolts through the corresponding four first mounting holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The scraper is clamped on the support plate to initially limit the scraper, and the scraper is fixed to the support plate by passing four fastening bolts through the corresponding four first mounting holes, thereby achieving quick installation of the scraper. By removing the four fastening bolts, the scraper is no longer limited, and then the scraper is pulled with a greater force to separate it from the support plate, thereby facilitating quick disassembly and replacement of the scraper, which can avoid the situation where the entire equipment is scrapped due to local damage. By clamping the connecting pipe on the standard rod and then installing the extension rod on the standard rod, the length of the slag remover operating rod can be adjusted to adapt to different usage requirements, which is convenient for operators to work on the ground and for operators to operate on the workbench. The coordinated arrangement of the left reinforcement plate, the right reinforcement plate and the tail reinforcement plate can improve the structural strength of the slag removal unit, making the slag removal unit more durable. The scraper is made of high-speed steel, which reduces manufacturing costs while ensuring sufficient wear resistance. The blade adopts a vertical surface to increase the strength of the blade.
