Specific embodiments

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, a press with limit protection includes a processing table 1 and a protective component 3. An outer protective cover 2 is arranged at the upper end of the processing table 1. The protective component 3 for preventing splashing and performing limit protection is arranged inside the outer protective cover 2. The protective component 3 includes a bottom ring 301, a protective piece 302, an adjusting ring 303, a connecting plate 304, and a hydraulic rod 305. The upper end of the bottom ring 301 is connected to the protective piece 302. The protective piece 302 plays a role in external range protection during product processing, avoiding the danger caused by workpiece damage and splashing or the displacement of the workpiece itself during processing, providing range limit protection for the processed product, increasing safety. The upper end of the protective piece 302 is connected to the adjusting ring 303. The side of the adjusting ring 303 is provided with a connecting plate 304, and the lower end of the connecting plate 304 is provided with a hydraulic rod 305. The bottom ring 301 and the adjusting ring 303 are arranged in parallel, and two groups of connecting plates 304 and hydraulic rods 305 are symmetrically arranged about the vertical central axis. The adjusting ring 303 is lifted and adjusted by the connecting plate 304 under the drive of the hydraulic rod 305, so as to play the role of opening, closing, and storing the protective piece 302.

[0023] As Figure 2 and Figure 3As shown, a pressure platform 4 is provided inside the bottom ring 301. The pressure platform 4 is used for placing the product to be processed. Two auxiliary rods 501 play a role in side limiting on both sides of the workpiece located on the pressure platform 4, avoiding the initial displacement of the workpiece when it is stressed. An auxiliary component 5 for assisting the workpiece to prevent deviation is provided outside the pressure platform 4. The auxiliary component 5 includes an auxiliary rod 501 and a moving plate 502. A moving plate 502 is installed on the side of the lower end of the auxiliary rod 501. The auxiliary component 5 further includes a spring 503 and a moving rail rod 504. A spring 503 is installed on the side of the moving plate 502. When the pressure is too high, the workpiece pushes the auxiliary rod 501 to move and stretch the spring 503, causing the auxiliary rod 501 to move accordingly, avoiding damage to the auxiliary rod 501. A moving rail rod 504 is provided outside the spring 503. The resilience of the spring 503 causes the auxiliary rod 501 to approach the side of the workpiece. The cylindrical hollow moving rail rod 504 is used for the installation and external protection of the spring 503. A hydraulic press 6 is installed on the top of the outer protective cover 2. The output end of the hydraulic press 6 is provided with a pressure plate 7. An installation strip 8 is installed at the upper end of the front side of the outer protective cover 2.

[0024] In summary, for the press with limit protection, first, according to Figures 1-3 the structure shown in the figure, during processing, the workpiece to be processed is placed on the pressure platform 4, and the two auxiliary rods 501 are respectively pulled to move them to both sides. When the auxiliary rods 501 move, the spring 503 is stretched. At this time, the resilience of the spring 503 enables the auxiliary rods 501 to limit the workpiece on both sides. During processing, the pressure plate 7 is driven by the hydraulic press 6 to press the workpiece on the pressure platform 4 into shape. During processing, the hydraulic rod 305 extends to drive the connecting plate 304 to drive the adjusting ring 303 to move upward, causing the protective piece 302 to unfold. At this time, the protective piece 302 plays an external range protection role during product processing, avoiding the danger caused by the workpiece being damaged and splashing or the workpiece itself moving during processing, providing range protection for the processed product, increasing safety. At the same time, during workpiece processing, when the forming pressure of the workpiece increases and the workpiece deforms, the deformed side of the workpiece can push the auxiliary rod 501 to move and stretch the spring 503, causing the auxiliary rod 501 to move accordingly, avoiding damage to the auxiliary rod 501 for subsequent use.
