Problems solved by technology

[0002] There are two existing gear processing methods, one is the forming method, which is to use a forming milling cutter that completely matches the shape of the tooth groove of the gear to be cut to cut out the tooth shape, and the other is the generating method, which uses the gear tool The processing method of cutting out the tooth profile through the mutual meshing movement with the driven gear. Both methods have a common feature that the tooth grooves are milled one by one. The disadvantage is that it is labor-intensive and time-consuming.

Embodiment approach

[0051] The specific implementation method first introduces the machining process of spur gears, such as Figure 21 As shown in (TU-A), the starting equipment lifts the lifting plate, puts the turned gear blank into the workpiece boss of the pressure-bearing rotating shaft of the pressure-bearing rotating system, adds pads and installs lock nuts to fix it, and the gear blank at this time is Like a perforated discus with neat edges, its shape is a hollow cylinder with an outer diameter of Φ102mm, a thickness of 20mm, and a hole diameter of Φ35mm. Start the hydraulic pump and open the pressurizing valve to pressurize the hydraulic cylinder. The hydraulic column is pushed out to push the lifting plate to move downward. Figure 21 As shown in (TU-B), the ring-shaped evenly distributed cutter head on the first shoveling piece of the multi-head rail-fixed stepped shoveling die gradually cuts the workpiece, and cuts out 32 uniformly distributed shallow grooves with a depth of 0.30mm a...

Abstract

The invention discloses hydraulic multi-head fixed rail backing-off cutting cylindrical gear one-step molding equipment. Hydraulic equipment serves as lifting power, an echelon annular fixed rail multi-head backing-off cutting molding mold serves as a machining cutter, and a gear blank can be machined into a straight tooth cylindrical gear or an oblique tooth cylindrical gear in the lifting process, so that the gear machining time is greatly shortened, tedious labor in a single-slot machining process is eliminated, the precision of a finished gear is improved, and a new way is created for machining gears in the machinery manufacturing industry.

Description

Technical field: [0001] The invention belongs to the field of cylindrical gear processing and forming. Background technique: [0002] There are two existing gear processing methods, one is the forming method, which is to use a forming milling cutter that completely matches the shape of the tooth groove of the gear to be cut to cut out the tooth shape, and the other is the generating method, which uses the gear tool The processing method of cutting out the tooth profile through the mutual meshing movement with the driven gear, both methods have a common feature that the tooth slots are milled one by one, and the disadvantage is that it is labor-intensive and time-consuming. Invention content: [0003] We have invented a hydraulic multi-head rail-fixed step-by-step shoveling cylindrical gear forming equipment. The hydraulic equipment is used as the lifting power, and the step-by-step annular rail-fixed multi-head shovel forming mold is the processing tool. The gear blank can...
