Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a pressure-adjustable hydraulic press, comprising a hydraulic press 1 that can process a workpiece, a hydraulic plate 3 is arranged inside the hydraulic press 1, a bearing plate 4 for providing support is arranged on the inner wall of the hydraulic press 1 near the bottom of the hydraulic plate 3, a protective component for blocking the splashing of the workpiece by the extruded material is arranged on the left side of the hydraulic press 1, the protective component comprises a baffle 2 that can block the splashing workpiece material, a shift block 23 for driving a slider 25 to move is slidably connected to the left side of the baffle 2, a slider 25 for providing support is fixedly connected to the right side of the shift block 23, the slider 25 is slidably connected to the front surface of the baffle 2, and a positioning block 22 for positioning the slider 25 is fixedly connected to the top of the slider 25.

[0032] Furthermore, the positioning block 22 is slidably connected to the inner wall of the baffle 2, and the slider 25 is elastically connected to the baffle 2 through a spring 21. The slider 25 moves inward to squeeze the spring 21, and the reverse force of the spring 21 being squeezed can drive the slider 25 to move outward and slide into the slide groove 26, thereby supporting the baffle 2. The inner wall of the left end of the hydraulic press 1 is provided with a slide groove 26 for providing movement of the slider 25, and the slider 25 slides on the inner wall of the slide groove 26.

[0033] Reference Figure 1 , Figure 3 , Figure 4 The bottom end of the hydraulic plate 3 is provided with a buffer component which can reduce the pressure on the workpiece after pre-contacting the workpiece, so that the workpiece can be squeezed slowly to avoid damage caused by direct impact. The buffer component includes an extrusion plate 31 for squeezing the workpiece, and the top end of the extrusion plate 31 is fixedly connected with a slide rod 35 for providing support, and the slide rod 35 passes through and is slidably connected to the top end of the hydraulic plate 3.

[0034] Reference Figure 1 - Figure 3The left side of the inner wall of the left end of the hydraulic press 1 is close to the left side of the second slide groove 26, and a slide groove 24 is provided to provide movement of the slider 25. The slider 25 slides on the inner wall of the slide groove 24, and the inner wall of the left front surface of the slide groove 24 is set as an inclined surface. The left front surface of the slide groove 24 is set as an inclined surface, so that when the slider 25 slides into the slide groove 24, it is first squeezed against the inclined surface of the slide groove 24, so that the slider 25 can be moved inwardly through the inclined surface to squeeze the spring 21, and at the same time, the slider 25 can slide into the slide groove 24. When the slider 25 is slid in the slide groove 24 to align with the slide groove 26, the reverse force of the spring 21 being squeezed can drive the slider 25 to reset and slide into the slide groove 26 to provide support and limit. The slide groove 24 is connected to the second slide groove 26. One end of the spring 21 is fixedly connected to the inner wall of the baffle 2, and the other end of the spring 21 is fixedly connected to the rear surface of the slider 25.

[0035] Reference Figure 1 , Figure 3 A block 28 for providing support and guidance is fixedly connected to the right side of the baffle 2, and a positioning plate 32 for providing support and guidance is fixedly connected to the left side of the hydraulic plate 3. A slot 27 is provided on the left side of the positioning plate 32, and the block 28 slides on the inner wall of the slot 27. The block 28 slides into the slot 27 to support the baffle 2, and at the same time, the baffle 2 can be driven to move when the hydraulic plate 3 moves.

[0036] Reference Figure 1 , Figure 3 , Figure 4 The outer wall of the slide bar 35 is fixedly connected with a positioning plate 34 for providing support. The positioning plate 34 is arranged at the top of the hydraulic plate 3. The hydraulic plate 3 supports the positioning plate 34 and the slide bar 35 at the same time. The extrusion plate 31 is supported by the slide bar 35. The extrusion plate 31 and the hydraulic plate 3 are elastically connected by a second spring 33. One end of the second spring 33 is fixedly connected to the bottom end of the hydraulic plate 3, and the other end of the second spring 33 is fixedly connected to the top of the extrusion plate 31. The second spring 33 is sleeved on the outer wall of the slide bar 35. After the extrusion plate 31 moves and contacts the workpiece in advance, the workpiece is pre-clamped and positioned. At the same time, after the workpiece is squeezed, it is reversely squeezed by the workpiece to squeeze the second spring 33. The second spring 33 makes the hydraulic plate 3 drive the extrusion plate 31 to contact the workpiece slowly and smoothly, reducing the pressure of squeezing the workpiece and avoiding damage caused by direct impact. At the same time, according to the stiffness and pre-compression amount of the second spring 33, the pre-extrusion force of the extrusion plate 31 on the workpiece can be adjusted to protect the workpiece from damage, improve the processing quality, and increase the service life of the workpiece.

[0037] Working principle: When in use, the slider 25 is driven to move by moving the baffle plate 2, so that after the slider 25 slides into the slide groove 1 24, it contacts the inclined surface of the inner wall of the left front surface of the slide groove 1 24, and by squeezing the inclined surface, the slider 25 moves inward, driving the positioning block 22 and the shift block 23 to move and squeezing the spring 1 21 at the same time. When the slider 25 slides through the slide groove 1 24 to align with the slide groove 26, the reverse force of the spring 1 21 can reset the slider 25 and slide into the slide groove 26, so that the baffle plate 2 can be supported. At the same time, the movement of the baffle plate 2 will drive the block 28 to move, so that the block 28 slides into the slot 27, so that the hydraulic plate 3 can be connected with the baffle plate 2, which improves the convenience of installing the baffle plate 2. At this time, after the baffle plate 2 is installed, protection can be performed, so that the material splashed out of the hydraulic press 1 can be blocked to prevent the splashing from causing danger to the operator, thereby improving safety.

[0038] When the hydraulic plate 3 moves upward, the positioning plate 32 can be driven to move upward. The upward movement of the hydraulic plate 3 can drive the baffle 2 to move upward. The synchronous movement of the baffle 2 can prevent the baffle 2 from blocking the operator's operation, thereby improving the convenience of operation.

[0039] After placing the workpiece to be processed on the supporting plate 4, the hydraulic press 1 is started to drive the hydraulic plate 3 to move downward, and at the same time drive the extrusion plate 31 to move and contact the workpiece for pre-clamping and positioning. The extrusion plate 31 is squeezed after the workpiece is squeezed, so that the spring 2 33 is squeezed by the extrusion plate 31, and at the same time, the slide bar 35 and the positioning plate 34 move upward, and the spring 2 33 is squeezed so that the extrusion plate 31 is reversely squeezed to the workpiece. According to the stiffness and pre-compression amount of the spring 2 33, the pre-extrusion force of the hydraulic plate 3 on the workpiece can be adjusted, which helps to contact the workpiece slowly and smoothly, avoid damage caused by direct impact, protect the workpiece from damage, improve the processing quality, and increase the service life of the workpiece.
