2results about How to "High cutting surface quality" patented technology

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.
