Problems solved by technology

The disadvantage is that there are many processes and the cost is high, and it is difficult to process the gear shaft
Although there are many reasons, the most important thing is the lack of high-efficiency, high-precision, and low-cost processing devices

Embodiment Construction

[0030]In Fig. 1, Fig. 2, the casing 6 of drum shape is shaped on guide hole in it. A center is shaped on the end cover 9 that handling hole 14 is housed on its top port. This loading and unloading hole 14 can be a taper hole, and it is loading and unloading workpiece, observes working situation, is again refueling, cooling, cleans a window reserved inside. The casing 6 can be placed upright, upside down, or sideways. The end cover 9 is also shaped on uniformly distributed circular holes for 6 to 12 force transmission columns 10 to pass through. The end cover 9 is fixed on the port of the casing 6 by the bolt 7 . The center of the bottom of the casing 6 is formed with an upwardly extending cylindrical pedestal. The center of the cylindrical pedestal has a top 11 for the workpiece tooth blank 1 to stand upright, and elastic clamps 3 are arranged on its periphery. There is a tapered ring 5 that can move up and down in the casing 6, the outside of the tapered ring 5 is slidingl...

Abstract

The invention discloses a device for processing gear by inlaid-pressure formation, which comprises a cylindrical housing (6) with a guide hole, and a conical ring (5) making vertical movement in the guide hole, wherein tooth-shaped inserts (2) are in sliding match with a radial guide groove of an assembled insert base (4) and are distributed on a cylindrical surface of a gear blank workpiece to be processed around a center; pressurization equipment applies an axial pressure Py to the conical ring from the top to push a bevel surface in the conical ring to descend and produce a radial pressurePx, so that the tooth-shaped edge notch of the tooth-shaped inserts (2) extrude the axial blank material of the gear blank workpiece (1) along a contact path to produce plastic deformation of the axial blank material so as to obtain a gear with a profile consistent with the tooth-shaped inserts (2). The device can process gear shafts and non-integral gears or integral gears by changing different tooth-shaped inserts, and is applicable for processing various tooth profiles such as involute, cycloid, helical gear and bevel gear. The processed gear has high yield, and the mold cutting tools can be easily standardized and can be used repeatedly to achieve high efficiency and low cost.

Description

technical field [0001] The invention relates to a device for manufacturing gears without cutting, in particular to a device for manufacturing pinion shafts and non-integral gears by insert forming and processing gears. technical background [0002] The gear cutting and processing equipment in the prior art includes: gear hobbing machine, gear shaper, gear shaving machine, gear honing machine, gear broaching machine, etc., although they are all mature processes that can effectively process gears, most of them cannot process gear shafts and non- Complete gear, and there is metal waste, waste material equipment. [0003] The tooth milling method in the prior art utilizes a disc gear milling cutter to cooperate with an indexing mechanism to process a single tooth on a milling machine. Although gear shafts and incomplete gears can also be processed, the resulting tooth profile often has large errors, low machining accuracy, low production efficiency and high cost. This method i...
