Embodiment

[0030] The invention discloses a heating stamping and riveting process of a gear box, such as Figure 1 to Figure 6 shown, including the following steps:

[0031] a. Integrated blanking, punching and edge deburring, blanking die 1 punches and blanks from one side of the sheet metal part, punching and deburring integrated die 2 punches from the other side of the sheet metal part, including punching And flatten the burr, directly integrated stamping to obtain the first semi-finished product 3;

[0032] B, heating stamping flanging, the first semi-finished product 3 that makes in the step a is moved to the flanging station, the first semi-finished product 3 is heated by the support platform of the flanging station, and the flanging mold 4 is self-heating; The side mold 4 punches the heated first semi-finished product 3 out of the flanging to obtain the second semi-finished product 5;

[0033] c. Riveting the gear shaft 7, moving the second semi-finished product 5 prepared in st...

Abstract

The invention discloses a heating stamping and riveting process for a gear gearbox. The heating stamping and riveting process comprises the following steps that a, integration blanking, punching and edge deburring are conducted to obtain a first semi-finished product; b, heating stamping and flanging are conducted, specifically, a heated flanging die stamps the heated first semi-finished product to enable the first semi-finished product to be provided with turned edges to obtain a second semi-finished product; and c, gear shafts are riveted, the second semi-finished product is subjected to heat preservation control, a riveting clamp clamps the gear shafts and heats the riveting parts of the gear shafts, the riveting clamp enables the heated gear shafts to be embedded into the second semi-finished product, and a riveting die enables the riveting parts of the gear shafts and the second semi-finished product to be connected in a pressed mode to obtain a third semi-finished product. Blanking, punching and deburring are finished through integration stamping, the steps are simplified, the machining accuracy of bending and gear shaft riveting is improved, the riveting parts of the gear shafts do not protrude out of the gearbox surface, thus dressing is not needed, and the riveting strength is high.

Description

technical field [0001] The invention relates to the technical field of sheet metal parts processing, in particular to a heating stamping and riveting process of a gear box. Background technique [0002] Gearboxes, especially gearboxes with gear shafts, have high requirements for the installation accuracy of the gear shafts, otherwise the installation and meshing of the gears will be affected, and the service life of the gears will be affected. [0003] At present, the processing steps for the gear box are complicated: blanking, punching, deburring, step-by-step bending, riveting the gear shaft, trimming the riveting part, etc. In the riveting of the gear shaft, often due to the problem of riveting precision, the gear box cannot meet the requirements of use, and the reject rate is high. Contents of the invention [0004] Purpose of the invention: The present invention discloses a heating stamping and riveting process of a gear box, which completes blanking, punching and de...
