This invention relates to a teardrop-shaped chip divider for precision broaching of tenon grooves in aero-engines, belonging to the field of aero-engine manufacturing technology. The chip divider features a smooth contour composed of arcs and straight lines within a specific range, and is tangentially connected to the back face of the cutting teeth. This results in a large, smooth, streamlined cross-section without sharp points, effectively solving the industry problem of sharp-cornered chip dividers scratching the machined surface of the workpiece during precision broaching. While ensuring chip breaking and chip separation functions, it significantly improves the surface roughness quality of the tenon groove. It is suitable for precision broaching of high-requirement parts such as compressor discs and fan discs, improving blade machining efficiency.

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.

This utility model provides a corner rounding grinder, including a bakelite milling machine. The milling cutter of the bakelite milling machine is a corner rounding cutter. A guide rail is fixedly installed on the grinding end of the bakelite milling machine. The extension direction of the guide rail is perpendicular to the rotation axis of the corner rounding cutter. A fixed frame is slidably installed on the guide rail. The fixed frame includes a guide plate and multiple positioning pins. The guide plate is slidably installed on the guide rail and slides back and forth along the guide rail. The positioning pins are fixedly installed on the guide plate. The multiple positioning pins clamp and fix the workpiece to be processed, so that the corner position of the workpiece is fixed in the cutting area of ​​the corner rounding cutter. The beneficial effects of this utility model are: through the guide rail system set perpendicular to the axis of the milling cutter, the sliding guide plate drives the fixed frame to clamp the workpiece and feed it in a straight line, ensuring that the corner of the workpiece is accurately positioned in the cutting area of ​​the milling cutter, which significantly improves the rounding accuracy; the return spring buffers the cutting vibration and prevents overcutting caused by workpiece displacement. At the same time, the handle keeps the operator's hand away from the cutter head, completely eliminating the risk of cutting injury.

This utility model relates to the field of PVC pipe processing and discloses a PVC pipe sawing device that facilitates safe clamping. It includes a base and a clamping motor. The clamping motor is fixedly connected to the rear of the base, and a gear is fixedly connected to the output shaft of the clamping motor. The front and rear ends of the gear are respectively meshed with gear rails, and each gear rail has a set of movable seats fixedly connected to its top. This PVC pipe sawing device, by setting up clamping plates, allows for clamping. During clamping, a cylinder is activated, pushing the clamping plates forward via a connector to adjust the clamping position. Then, the clamping motor is activated, driving the gear to rotate, causing the two sets of gear rails to move relative to each other. The two sets of fixed plates then move relative to each other, allowing the two clamps to clamp the PVC pipe from the side. This achieves the action steps of first determining the distance and then clamping, facilitating segmented, fixed-distance cutting with the saw blade. The automatic clamping process is safer and solves the safety problems associated with manual clamping.

The application belongs to the technical field of shaft sleeve processing, and discloses a processing method of a marine shaft sleeve and the marine shaft sleeve. First, the shaft sleeve original piece is installed on a processing device, and the processing angle of a processing tool is adjusted, so that the processing tool is used for three-time cutting processing of the shaft sleeve original piece with different angle schemes and different cutting processing parameters of cutting speed, feed rate and cutting depth, to form a shaft sleeve inner hole. Then, a polishing device is used to polish the hole wall of the shaft sleeve inner hole with a preset processing scheme, until the hole diameter of the shaft sleeve inner hole is equal to the inner diameter of the marine shaft sleeve, and the roughness of the hole wall of the shaft sleeve inner hole is the preset roughness, so that the shaft sleeve original piece is formed into the marine shaft sleeve. The marine shaft sleeve is processed by using the processing method, so that the labor amount of workers can be reduced, the processing cost and the labor cost can be reduced, and the working efficiency of the processing of the marine shaft sleeve can be improved.
