Embodiment 1

[0030] The workpiece goes through five stretching processes, and the peripheral materials are gradually squeezed into the middle, forming the bottom of the plate and the platform that protrudes outward.

[0031] Process one (such as figure 2 (shown): Adjust D1 and L1 so that the diameter of the platform after the workpiece is stretched is 120mm, the height is 25mm, the radius of the inner arc of the platform is 20mm, and the radius of the outer arc at the connection between the platform and the bottom of the plate is 30mm;

[0032] Process two (such as image 3 (shown): Adjust D2 and L2 so that the diameter of the platform after the workpiece is stretched is 80mm, the height is 27mm, the radius of the inner arc of the platform is 15mm, and the radius of the outer arc at the connection between the platform and the bottom of the plate is 25mm;

[0033] Process three (such as Figure 4 (shown): Adjust D3 and L3 so that the diameter of the platform after the workpiece is stretc...

Abstract

The invention relates to a flywheel vibration-reducing system part inner fluted disc forming technology which includes five stretching procedures. A die comprises a pressing plate, an upper die block and a lower die block, the middle of the low die block is provided with a lower die core, the diameter of an inner cavity of the upper die block gradually reduces in the five stretching procedures, and the distance between the upper die block and the lower die block gradually increases. The flywheel vibration-reducing system part inner fluted disc forming technology has the advantages that a peripheral material of a workpiece is extruded to the middle gradually after the five stretching procedures, and it is guaranteed that the material has a certain thickness.

Description

technical field [0001] The invention relates to a forming process of an internal gear plate of a part of a flywheel damping system. Background technique [0002] Punching and turning holes are often used in the forming of the internal gear plate of the flywheel damping system parts, which often makes the thickness of the material seriously thinner and fails to meet the requirements of the drawing. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a forming process for the inner gear plate of the part of the flywheel damping system. [0004] A technical solution adopted by the present invention to solve the technical problem is: a forming process of the internal gear plate of the part of the flywheel damping system, including the following steps: [0005] a. Use the mold to stretch the workpiece for the first time. The mold includes a pressure plate, an upper module...
