The sliding engagement between the slide block 408 and the slide slot 407 guides the lifting movement of the sliding upper die body 403. Further, the top surfaces of the left upper die body 401 and the right upper die body 402 are fixedly provided with a limiting block 409 above the top ends of the sliding groove 407, so that in the stamping operation state, the sliding upper die body 403 can move upwards relative to the left upper die body 401 and the right upper die body 402 until the top surfaces of the sliding blocks 408 abut against the bottom surfaces of the limiting block 409 to stop moving relatively, and at the moment, two ends of the bottom surfaces of the sliding upper die body 403 are respectively and smoothly connected with the bottom surfaces of the left upper die body 401 and the right upper die body 402 to form a complete arc surface so as to match the top surfaces of the lower die 6 to realize the stamping molding of the plate 100.
As shown in fig. 5 and 6, the pre-clamping assembly 7 comprises a guide plate 701 fixedly arranged on the side end of the mounting cylinder 5, a side plate 702 fixedly arranged on the outer end side of the guide plate 701, a moving frame 703 slidably arranged on the top of the guide plate 701, and a pre-clamping frame 704 fixedly arranged on the inner side of the top of the moving frame 703, wherein the vertical section of the pre-clamping frame 704 is in a shape of 'C', a second connecting rod 706 is fixedly arranged on the outer side surface of the moving frame 703, and a second spring 707 sleeved on the outer side of the second connecting rod 706 is arranged between the moving frame 703 and the side plate 702. After the plate 100 to be formed is placed on the top surface of the lower die 6, two ends of the plate 100 are respectively inserted into two preassembled inserting frames 704 positioned at two ends of the lower die 6, and under the action of the elastic force of the second springs 707, the side walls of the preassembled inserting frames 704 are abutted against the end parts of the plate 100, and since the two preassembled inserting frames 704 are symmetrically arranged at two sides of the lower die 6, the plate 100 can be horizontally and transversely centered on the lower die 6, as shown in fig. 7. The bottom surface of the moving frame 703 is slidably connected to the top surface of the guide plate 701 through a T-shaped chute structure, so that the moving frame 703 can horizontally and laterally move on the guide plate 701 relative to the lower die 6. Preferably, a baffle 705 is fixedly disposed at one end of the pre-installed inserting frame 704, and in the process of placing the board 100 on the top surface of the lower die 6 and inserting the two ends of the board 100 into the two pre-installed inserting frames 704, the two edges of the rear side of the board 100 are respectively abutted against the two baffles 705, so that the preliminary positioning of the board 100 in the horizontal longitudinal direction can be realized. Meanwhile, since the driving motor 10 drives the mounting cylinder 5 to realize position switching at a unit stepping angle of 90 degrees, when the preassembled jack 704 is in a vertical position state, the baffle 705 can support the plate 100 to prevent the plate 100 from falling off from the preassembled jack 704.

The slope on the pre-load jack 704 is always located below the lateral slope of the wedge 4010 throughout the stamping process so that the pre-load jack 704 does not create a motion barrier to the upward reset of the upper die assembly 4. When the upper die assembly 4 is reset upward, the pre-load socket 704 moves horizontally inward and resets under the elastic restoring force of the second spring 707.
In order to realize the synchronization and continuous execution of plate feeding, stamping forming and blanking, so as to synchronously utilize the intermittent time among working procedures, improve the production working efficiency, the four sides of the installation cylinder 5 are respectively provided with a lower die 6, and a group of oppositely arranged pre-clamping assemblies 7 are arranged at the two ends of each lower die 6, as shown in fig. 8.

Two electrode assemblies 1 are fixedly arranged on the top surface of the substrate 11 respectively, and the two electrode assemblies 1 are respectively positioned on the lower inner sides of the two bottommost pre-clamping assemblies 7. As shown in fig. 11, the electrode assembly 1 includes a second cylinder mount 101 fixedly attached to the top surface of the base plate 11, an electrode cylinder 102 fixedly attached to the second cylinder mount 101, and a power supply electrode 103 fixedly attached to the output rod end of the electrode cylinder 102. The two power supply electrodes 103 on two sides are respectively connected with the two input electrodes of the external high-frequency pulse current, and when the two electrode cylinders 102 work synchronously or successively positively, the two power supply electrodes 103 respectively collide with two ends of the bottom surface of the plate 100 in the pre-clamping assembly 7 loaded at the bottom, so that the clamped plate 100 can be electrified and heated, the stamping deformation performance of the plate 100 is improved, and the forming is facilitated.
After the plate 100 is heated to a preset temperature (the specific temperature is determined according to various actual parameters such as the material and thickness of the plate), the mounting cylinder 5 rotates 90 degrees anticlockwise, two preassembled inserting frames 704 loaded with the plate 100 are vertically arranged, the side openings of the two preassembled inserting frames face upwards, the baffle 705 on the two preassembled inserting frames are positioned below the plate 100, and the plate 100 can automatically adjust the position downwards under the action of self gravity and extend into the preassembled inserting frames 704. And the next lower die 6 and the corresponding pre-clamping assembly 7 are switched from the front side position of the mounting cylinder 5 to the bottom of the mounting cylinder 5, so that the automatic feeding and the electrified heating of the plate 100 can be continuously finished.
The plate positioning assembly 2 is fixedly arranged on the top of the inner wall of the side supporting plate of the portal frame 12. In this embodiment, the plate positioning assemblies 2 are provided in two, and are symmetrically arranged on the portal frame 12 in a left-right direction. As shown in fig. 12, the panel positioning assembly 2 includes a first cylinder mounting bracket 201 fixedly connected to the top of the inner side surface of the side support plate of the portal frame 12, a positioning cylinder 202 fixedly mounted on the first cylinder mounting bracket 201, and a positioning baffle 203 fixedly connected to the output rod end of the positioning cylinder 202. When the output rod of the positioning cylinder 202 is extended, the positioning baffle 203 is located at the front side of the uppermost pre-clamping assembly 7, and after the mounting cylinder 5 is rotated counterclockwise by 90 ° again, the plate 100 located at the rear side of the mounting cylinder 5 is switched to the top position of the mounting cylinder 5, which is the press forming position.

Then, the hydraulic cylinder 13 drives the upper die assembly 4 to move downward, and the hot stamping process of the plate 100 is completed in cooperation with the lower die 6. After the stamping forming is completed, the hydraulic cylinder 13 drives the upper die assembly 4 to move upwards for resetting, and the positioning cylinder 202 drives the positioning baffle 203 to move upwards for resetting. When the output rod of the positioning cylinder 202 is contracted, the positioning baffle 203 is positioned at the upper side of the top of the uppermost pre-clamping assembly 7, so that the lower die 6 loaded with the formed workpiece can smoothly pass through the lower space of the positioning baffle 203 when the mounting cylinder 5 is rotated.
In order to ensure that the mounting cylinder 5 can maintain a stable position in the stamping forming process, a locking component 8 is fixedly arranged on the outer side of a side supporting plate on one side of the portal frame 12 away from the driving motor 10.

Preferably, four plugging holes 501 which are circumferentially uniform around the axis of the mounting cylinder 5 are formed in the end face of the mounting cylinder 5, the locking assembly 8 is arranged into an upper group and a lower group, and the two plugging holes 501 are synchronously plugged and matched through two plugging blocks 803, so that the stability of the mounting cylinder 5 in the stamping forming pose is further enhanced.
After the punching operation of the plate member 100 is completed, the lock cylinder 802 is operated in the reverse direction, and the output rod thereof pulls the insertion block 803 to move horizontally so as to be separated from the mounting cylinder 5 and to stay in the side support plate of the gantry 12. After the mounting cylinder 5 is rotated again by 90 degrees counterclockwise, the formed workpiece at the top of the mounting cylinder 5 is switched to a position at the front side of the mounting cylinder 5, which is a blanking position. Since the two ends of the formed workpiece are not acted by the pre-clamping assembly 7, the formed workpiece naturally slides down along the surface of the lower die 6, and automatic blanking can be realized. Preferably, the front side of the top surface of the base plate 11 is fixedly provided with a blanking guide plate 14 positioned below the blanking position, the top surface of the blanking guide plate 14 is a concave arc surface, after the formed workpiece falls onto the surface of the blanking guide plate 14, the formed workpiece slides down to the front side position of the base plate 11 along the top surface of the blanking guide plate 14, and the formed workpiece can be transferred in a manual moving or material trolley transferring mode. The lower die 6 after the blanking is completed and the pre-clamping assemblies 7 at the two ends of the lower die can load a new plate 100 after the mounting cylinder 5 rotates in a next step.
