This utility model discloses a cutting device for refrigeration compressor castings, relating to the technical field of cutting equipment. It includes a stepper motor and a saw blade, and further includes a folding assembly. The bottom of the folding assembly is fixedly connected to the outer wall of the stepper motor via a frame. Buffer components are fixedly connected to the corners of the folding assembly. The folding assembly includes a main plate and a secondary plate connected by a hinge to form a foldable structure. When the device needs to be stored, the secondary plate can rotate around the hinge. The sliding connection structure between the insert and the threaded cylinder serves as a guide and limiter, ensuring a smooth and orderly folding process. Rotating the threaded cylinder pushes the limiter frame to slide along the outer wall of the threaded cylinder, causing the insert to move and match the insertion hole position of the folded main plate and secondary plate, achieving secure storage of the folding assembly. This cutting device achieves its purpose as a cutting device for refrigeration compressor castings.

The application provides a saw blade with staggered saw teeth, a saw blade production process and equipment, and relates to the technical field of composite material cutting processing. The saw blade with staggered saw teeth comprises a circular saw body, a plurality of first saw tooth portions and a plurality of second saw tooth portions are staggered along the circumferential direction on the outer periphery of the circular saw body, the first saw tooth portions and the second saw tooth portions are equal in number and are arranged in sequence with intervals, the first saw tooth portions and the second saw tooth portions are staggered with each other, so that staggered cutting structures are formed between adjacent different types of saw teeth. The structure is beneficial to dispersing cutting force, reducing the load of a single saw tooth, improving the stability and durability of the saw blade, and facilitating the fracture and discharge of chips, thereby improving the cutting efficiency and processing quality.

The utility model discloses a plastic model scribing cutter which comprises a cutter body and a cutting edge, the cutter body is fixedly connected with the cutting edge, the cutting edge is positioned at one end of the cutter body in the cutting direction, and the cutting edge is made of superhard materials. The cutting edges made of different materials are fixed in the cutting direction of the cutter body, and the cutting edges are made of super-hard materials, so that the advantages that the affinity of super-hard materials and plastic resin is low, cuttings easily flow out, and the quality of the cutting surface is good are fully played in the cutting and scribing process of a plastic (plastic cement) model; and the cutting quality and the model making and transforming efficiency of a user are greatly improved. Meanwhile, the existing mature ultra-high hardness material cutting edge is welded and fixed, so that the cutting edge, the knife body and the knife handle are separately manufactured, the knife handle and the knife body can be made of materials with lower technical requirements and lower cost, such as domestic conventional tungsten steel, and double effects of high-quality cutting and scribing and low-cost manufacturing can be realized.
