Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a bevel gear processing device. Background Art

[0002] Powder metallurgy is the process of producing metal powders or using metal powders as raw materials, forming and sintering them to create metal materials, composite materials, and various other products. Powder metallurgy technology is an advanced component manufacturing technology that is energy-efficient, material-efficient, environmentally friendly, highly efficient, low-cost, and produces near-net-shape parts. Its products are widely used in machinery, power electronics, automation, aerospace, automotive, and other fields.

[0003] Gear transmission is the most widely used transmission method in mechanical transmission. It can ensure stable transmission and has the advantages of high transmission efficiency and long service life. In the past, during the processing of bevel gears, the heated blank needed to be forged and then the shaft hole needed to be drilled. Drilling the shaft hole would generate a large amount of debris, reducing the utilization rate of the raw materials and the processing efficiency. Utility Model Content

[0004] The utility model aims to solve the above problems and thus provides a bevel gear processing device.

[0005] The utility model solves the above problems by adopting the following technical solutions:

[0006] A bevel gear processing device includes a forging die assembly and a punching assembly. The forging die assembly includes a tooth die for forming the bevel tooth end of the forged bevel gear and a concave die for forming the other end of the forged bevel gear. The tooth die and the concave die are combined to form a forging cavity. A protrusion is provided at the top center of the tooth die and the bottom center of the concave die relative to each other. The protrusion is used to preliminarily form the shaft hole of the bevel gear. The punching assembly includes a positioning base and a punch.

[0007] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0008] The utility model can reduce the weight of the blank to be used, improve the utilization rate of raw materials, reduce the heating time, save electric energy, change the drilling process into punching, and greatly improve the production efficiency by providing the protruding part.

[0009] As a preferred embodiment, a further technical solution of the present invention is:

[0010] The protrusion is in the shape of a truncated cone as a whole, and the end face is rounded, so as to facilitate demoulding.

[0011] A through hole is opened on the positioning base, the diameter of the through hole is larger than the diameter of the shaft hole of the bevel gear to be processed, and the size of the punch is adapted to the shaft hole of the bevel gear to be processed; the initially formed shaft hole of the bevel gear is finally punched. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic structural diagram of the punching assembly in use according to an embodiment of the utility model;

[0014] The markings in the figure are: die 1, tooth die 2, forging cavity 3, protrusion 4, positioning base 5, punch 6, and bevel gear to be processed 7. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0016] See also Figure 1-Figure 2 A bevel gear processing device includes a forging die assembly and a punching assembly. The forging die assembly includes a tooth die 2 for forming the bevel tooth end of the forged bevel gear, and a die 1 for forming the other end of the forged bevel gear. The tooth die 2 and the die 1 are combined to form a forging cavity 3. A protrusion 4 is provided at the top center of the tooth die 2 and the bottom center of the die 1. The protrusion 4 is used to preliminarily form the shaft hole of the bevel gear; the punching assembly includes a positioning base 5 and a punch 6.

[0017] The protrusion 4 is in the shape of a truncated cone as a whole, and the end surface is rounded to facilitate demoulding.

[0018] The positioning base 5 is provided with a through hole, the diameter of which is larger than the diameter of the shaft hole of the bevel gear 7 to be processed. The punch 6 is sized to fit the shaft hole of the bevel gear 7 to be processed. The preliminary formed shaft hole of the bevel gear is finally punched. When punching the bevel gear 7 to be processed, the bevel tooth end faces upward.

[0019] The utility model can reduce the weight of the blank to be used, improve the utilization rate of raw materials, reduce the heating time, save electric energy, change the drilling process into punching, and greatly improve the production efficiency by providing the protruding part.
