Trimming and thermal calibration tool for front shaft

Abstract

The invention relates to the field of trimming and thermal calibration tools for front shafts, in particular to a trimming and thermal calibration tool for post-forging of a front shaft. The tool comprises an upper die base and a lower die base and further comprises a trimming device and a calibration device. The trimming device is arranged between the upper die base and the lower die base. The calibration device is located on one side of the trimming device. The other side of the trimming device is further provided with a pushing device for pushing a workpiece to the calibration device through the trimming device. One side of the calibration device is provided with a reset device for pushing the calibration device to be closed and opened. During usage, the upper die base moves downwards to drive the trimming device to trim the workpiece, and the trimmed workpiece is pushed into the calibration device through the pushing device. The tool has the advantages that the structure is simple, the layout is compact, trimming, calibration and straightening of the front shaft can be achieved through one oil press, the equipment input is small, operation is easy and convenient, the automation degree is high, and the production quality and efficiency of products are improved.

Description

technical field [0001] The invention relates to the field of edge trimming and thermal correction tooling of the front axle, in particular to a tooling used for edge trimming and thermal correction of the front axle after forging. Background technique [0002] The forging process of the front axle of the automobile is as follows: induction heating, roll forging, pre-forging, final forging, edge trimming, and thermal correction. Flat, you also need to straighten the entire front axle. Such as Figure 1 to Figure 3 As shown, when the front axle workpiece 10 is being calibrated, the direction of the correction force applied to the leveling of the plate seat surface 101 and the workpiece alignment is different. During the calibration, it is necessary to divide the process into two steps and complete the calibration on two presses respectively. It is easy to cause the product space size to exceed the allowable difference, and the product quality is poor. The front axle needs to...

Problems solved by technology

[0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a trimming and thermal correction tooling of the front axle, which is used to solve the need for multiple presses to process the edge trimming and correction of the front axle separately in the prior art, The front axis calibration also needs to be carried out step by step. The equipment investment is large, the workpiece is inconvenient to move and transport, which affects the quality of processing calibration, low calibration efficiency, and high cost.
