[0024] The die stripping device of the utility model is arranged in the upper die part 1 of the vertical forging die of the automobile half-axle, and the upper die part 1 includes an upper module 11 and an upper die base 12. The upper module 11 is fixedly arranged at the bottom of the upper die base 12, and a forming cavity 13 for upsetting and gathering materials is arranged in the upper module 11. The die stripping device includes a beating block 2, a beating rod 3 and an elastic component 4. The beating block 2 is arranged in the upper module 11, and the lower end of the beating block 2 is arranged in the forming cavity 13. The beating rod 3 and the elastic component 4 are arranged in the upper die base 12. The elastic component 4 provides a downward elastic force to the beating rod 3, and the lower end of the beating rod 3 is arranged in contact with the beating block 2.

[0025] The forming cavity 13 is configured as a cylindrical structure, and the upper diameter of the forming cavity 13 is smaller than the lower diameter of the forming cavity 13, so as to achieve the upsetting operation of the upper end of the bar material.

Correspondingly, the beating block 2 is arranged to be cylindrical, and a first limiting ring 21 is arranged at the upper end of the beating block 2. The beating block 2 is arranged in the stripping guide section 142, and the first limiting ring 21 is arranged in the stripping limiting section 141. The outer ring diameter of the first limiting ring 21 is larger than the cross-sectional diameter of the stripping guide section 142 and smaller than the cross-sectional diameter of the stripping limiting section 141, so that the vertical movement of the beating block 2 under the limiting action of the first limiting ring 21 can be realized.

[0027] Preferably, an inclined transition section with a gradually decreasing cross-sectional diameter is provided between the stripping limit section 141 and the stripping guide section 142. Correspondingly, the connection position between the first limiting ring 21 and the material beating block 2 is set as an arc or an inclined transition.

[0028] The die stripping device of the utility model has no delay time of punching in traditional presses. The upper die can punch materials as soon as it moves upward.

The upper end of the punching rod 3 is arranged in the limiting sleeve 5 to ensure the vertical movement stability of the punching rod 3.

[0032] The elastic component 4 is configured as a butterfly spring, and a plurality of the butterfly springs are sleeved on the punching rod 3. Different stacking methods of the butterfly springs are improved based on actual needs. Springs with different layers can be used in forging production to achieve different punching forces. Specifically, stacking a single-leaf spring opposite to each other can provide a single punching force; stacking two springs in sequence and then stacking them opposite to each other can provide a double punching force; stacking three springs in sequence and then stacking them opposite to each other can provide a triple punching force. By disassembling and assembling the limit sleeve 5 to complete different stacking methods of the butterfly spring, the adjustment setting of different punching forces can be achieved.

[0033] The utility model arranges the beating block 2 and the beating rod 3 separately. The beating block 2 provides a controllable stripping stroke in the upper module 11, and the beating rod 3 provides a controllable stripping force in the upper die seat 12.

[0037] The upper mold part 1 is provided with a plurality of workstations. Under the control and drive of the hydraulic or electric control system of the press, each upper mold block 11 is moved forward and backward by a preset distance so that the upper mold of each workstation is aligned with the lower mold 61 .

[0038] The utility model sets different upper modules 11 and realizes the transformation of different forming stations through the linear sliding of the upper modules 11, so that the bar material set on the lower die part 6 can be subjected to multiple upsetting and gathering, so as to complete the forging of the flange part through a conventional press. Compared with other processing methods in the prior art, the equipment investment is small, the material utilization rate is high, the processing cost is low and the processing efficiency is high.

[0039] Generally, the lower end faces of the upper modules 11 are at the same height, so as to ensure that when the upper modules 11 are clamping the lower die 61, the downward stroke of the upper die 1 driven by the press is consistent, which is more convenient for continuous processing. At the same time, the mold stripping device is provided on each upper module 11 to realize rapid demolding after the processing is completed at each station, which is easier to realize the continuous processing state of the multiple upper dies of the vertical forging die for the automobile half-axle of the utility model, and realize rapid processing.

[0043] The fixing section is configured to be cylindrical, and the cross-sectional diameter of the fixing section is consistent with the cross-sectional diameter of the bar material, thereby facilitating the fixing of the bar material in the lower die 61 .

[0044] The lower template 62 is provided with a blanking hole 65 corresponding to the placement cavity 64 , and the diameter of the blanking hole 65 is larger than the cross-sectional diameter of the fixed section, so that waste oxide scale etc. generated during processing can be more easily leaked downward from the blanking hole 65 .

[0045] The lower die part 6 further includes a barrel 66, which is fixedly arranged on the workbench 63. A discharge hole 67 is vertically arranged in the barrel 66.

When the upper end surface of the punching block 2 hits the bottom surface of the upper die seat 12, the compression process of the butterfly spring ends, and the total compression of the butterfly spring is about 10mm, accumulating a certain amount of elastic deformation energy. The upper die portion 1 continues to move downward, and the heated part of the workpiece is pushed up and aggregated in the forming cavity 13 to complete the forming process.

[0051] The beating block 2 moves downward to beat the material: after forming is completed, the upper mold part 1 returns upward, and the elastic deformation energy accumulated in the butterfly spring is released, pushing the beating rod 3 and the beating block 2 downward, directly acting on the upper end of the workpiece. When the elastic force of the butterfly spring exceeds the friction force between the workpiece and the forming cavity 13, the workpiece can be knocked down, realizing automatic upward beating of the slider.
