Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel castings, and more particularly to a plasma cutting device for stainless steel castings. Background Art

[0002] Stainless steel castings are objects with a defined shape, size, and performance, obtained by pouring molten metal into a pre-prepared mold, cooling and solidifying, and then cleaning and polishing. Due to their excellent corrosion resistance and mechanical properties, stainless steel castings are widely used in various fields, such as machinery manufacturing, chemical equipment, food processing, and medical devices. Cutting is a key step in the manufacturing process of stainless steel castings, but traditional cutting methods often suffer from low efficiency and rough cut surfaces. Therefore, the development of an efficient and precise plasma cutting device for stainless steel castings is particularly important.

[0003] According to patent document: CN115502527A, a stainless steel casting plasma cutting device is disclosed, comprising a bracket and a support seat, wherein the bracket is fixedly mounted on the support seat, and grooves are provided on the inner walls on both sides of the bracket; a pulling mechanism is mounted on the bracket, and a plasma cutter is fixedly mounted on the pulling mechanism, and two plasma cutters are provided; two position adjustment mechanisms are provided and mounted in the grooves provided in the bracket, and the power output end of the position adjustment mechanism is fixedly connected to a placement groove, and the stainless steel casting to be cut can be placed on the placement groove and can follow the placement groove to approach or move away from the pulling mechanism; a clamping mechanism is mounted on the placement groove. The stainless steel casting plasma cutting device provided by the present invention can not only perform opposite cutting on the stainless steel casting, greatly improving the cutting efficiency, but also can adjust the cutting position of the stainless steel casting and can clamp the stainless steel casting at the same time, with simple operation and strong practicality.

[0004] After stainless steel castings cool and solidify and are cleaned and polished, they are usually processed into stainless steel pipes. After the stainless steel pipes are formed, they need to be cut to obtain pipe sections of the required length. Traditional cutting methods can only cut one surface, which is inefficient. In addition, after cutting, since the cut part is usually not equipped with a clamping device, the cut part will fall directly to the ground, which will not only cause material damage, but also pose a safety hazard to the operator. In addition, the plasma cutting process will produce harmful gases such as ozone and nitrogen oxides as well as metal dust. However, the existing cutting device cannot effectively deal with the harmful gases and metal dust generated during the cutting process, which may cause the operator to inhale harmful gases or come into contact with harmful dust, thereby endangering their health. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plasma cutting device for stainless steel castings. The technical problem to be solved by the present invention is: the traditional cutting method can only cut one surface, which is inefficient. In addition, after the cutting is completed, since the cut part is usually not provided with a clamping device, the cut part will fall directly to the ground, which will not only cause material damage, but also may pose a safety hazard to the operator. In addition, the plasma cutting process will produce harmful gases such as ozone and nitrogen oxides and metal dust.

The rack rod 128 drives the sector plate 129 to move The left and right sets of fan-shaped plates 129 move relative to each other to clamp and fix the stainless steel casting. After the cutting position adjustment is completed, the motor 2115 is started. The output end of the motor 2115 drives the turntable 2116 to rotate. The turntable 2116 drives the columnar cross sleeve 2217 to rotate through the crawler 2117 and the columnar cross sleeve 2219. The columnar cross sleeve 2217 drives the two control gear rods 2211 to rotate through the columnar cross rod 2215. The inner ends of the two control gear rods 2211 drive the two gear rods 2210 to rotate through the meshing action of the third gear 2212 and the fourth gear 2213. The outer ends of the two gear rods 2210 drive the two outer gear discs 225 to rotate through the meshing action of the fifth gear 2214 and the outer gear disc 225.Two outer tooth discs 225 drive two groups of plasma cutting heads 227 to rotate, and the two groups of plasma cutting heads 227 rotate to start cutting the stainless steel castings. In the process of cutting the stainless steel castings by the plasma cutting heads 227, the cutting speed can be controlled by adjusting the rotating speed of the motor 2115 to ensure the flatness and precision of the cutting surface.
