Closed forging device and production method for shaft products

Abstract

The invention discloses a closed forging device for shaft products. The closed forging device comprises a feeding device, a first transferring manipulator, a forging and pressing device, a second transferring manipulator and a heat treatment device which are arranged in sequence. The forging and pressing device is provided with a closed forging mold. The closed forging mold comprises a lower moldbody and an upper mold body with a convex part at the lower end. The outer wall of the convex part is attached to the mold cavity of the lower mold body. The lower mold body is provided with an ejection rod. The first transferring manipulator and the second transferring manipulator are arranged on the base, rotatably connected with the base and separately connected with a rotation driving device.Shaft products are forged in a closed forging mode, so that flanges and leftovers are avoided, and the rejection rate is low; and integrated conveying, forging, pressing and heat treatment is achieved, so that production efficiency and product quality are improved; and materials are saved, and labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of advanced manufacturing and automation, in particular to a closed forging equipment for shaft products. Background technique [0002] Gearbox parts have always been under a very harsh working environment, so the performance requirements for gearbox parts have always been much higher than ordinary parts. Gearboxes are dominated by shafts and gears, and forged products have always been the main production method for automotive gearbox parts because of their material saving, energy saving, high output, and high performance. [0003] At present, the forging of shaft products generally involves drawing, pre-forging, and final forging. The entire technological process has many procedures, large flash and material tails, and high energy consumption. The conventional forging and elongating process of medium and long shafts is manually operated, and it is difficult to grasp the length of accurate elongation durin...

AI Technical Summary

Problems solved by technology

There are many processes in the whole process, large flash and tail, and high energy consumption

The conventional forging and elongating process of medium and long shafts is manually operated, and it is difficult to grasp the length of accurate elongation during production, resulting in problems such as pre-forging folding or insufficient final forging, resulting in a low forging pass rate of shaft products, resulting in more waste products

However, in order to improve the pass rate, only the weight of the material can be increased, which will increase the amount of lathe processing and increase the cost of tools and labor costs.
