[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0027] Example 1

[0028] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a safety ejection mechanism for a hydraulic press, including a hydraulic press body 1 and a mold 2. A support plate 3 is fixedly connected to the inner side of the hydraulic press body 1. A rectangular groove 4 is formed in the middle of the top of the support plate 3. An ejection feeding mechanism 5 is provided in the inner cavity of the rectangular groove 4.

[0029] The feeding mechanism 5 includes two support platforms 51. A moving component 52 is provided at the bottom of the support platform 51, and a positioning component 53 is provided on the front and rear sides of the support platform 51.

[0030] Specifically, by setting the moving component 52, the two support platforms 51 can be moved, so that the two support platforms 51 can be fed alternately, thereby improving the continuity of workpiece processing.

[0031] By setting the positioning component 53, the workpiece on the top of the support platform 51 can be positioned when the support platform 51 is feeding, and the processed workpiece can be automatically released when the material is unloaded, making it convenient for the operator to pick up the material.

[0032] By setting up the support platform 51, the two support platforms 51 can alternately feed materials;

[0033] By setting the support plate 3 and the rectangular groove 4, the moving component 52 can be supported and limited.

[0034] Furthermore, during operation, the operator places the workpiece to be processed on the top of the left support platform 51, and then drives the two support platforms 51 to move to the right through the moving component 52. At this time, the left support platform 51 will enter the processing area of ​​the hydraulic press body 1, while the right support platform 51 will move out of the processing area.

[0035] As the left support platform 51 enters the processing area, the positioning components 53 on its front and rear sides will move closer to each other to clamp and position the workpiece on top of the support platform 51, ensuring that the workpiece will not shift during processing. As the right support platform 51 moves out of the processing area, the positioning components 53 on its front and rear sides will move further apart and open, making it easier for the operator to place the next workpiece to be processed on top of the right support platform 51.

[0036] When the left support platform 51 reaches the processing position, the hydraulic press body 1 is started, and the mold 2 presses down to process the workpiece. At the same time, the operator can place the next workpiece to be processed on the top of the right support platform 51. After the workpiece on the top of the left support platform 51 is processed, the hydraulic press body 1 drives the mold 2 to move up and reset. At this time, the moving component 52 runs in reverse, driving the two support platforms 51 to move to the left. The left support platform 51 moves out of the processing area, making it convenient for the operator to take out the processed workpiece, while the right support platform 51 enters the processing area.

[0037] Then, the hydraulic press body 1 is restarted to process the workpiece on the top of the right support platform 51. While the right workpiece is being processed, the operator can remove the finished product from the top of the left support platform 51 and place a new workpiece, waiting for the next processing cycle, thereby improving the continuity of processing.

[0038] Example 2

[0039] In the second embodiment of this utility model, the moving component 52 includes a servo motor 521 and a screw 522. The right side of the screw 522 is rotatably connected to the inner wall of the rectangular groove 4, and the left side of the screw 522 passes through the rectangular groove (4) and extends to the outside of the rectangular groove 4 and is fixedly connected to the output end of the servo motor 521. A moving plate 523 is sleeved on the surface of the screw 522 and is threadedly connected to the moving plate 523. The top of the moving plate 523 is fixedly connected to the support platform 51.

[0040] The front and rear sides of the servo motor 521 are fixedly connected to the fixing plate 6, the right side of the fixing plate 6 is fixedly connected to the support plate 3, and the front and rear sides of the moving plate 523 are fixedly connected to the slider 7.

[0041] The front and rear sides of the inner wall of the rectangular groove 4 are provided with sliding grooves 8. The side of the slider 7 away from the moving plate 523 passes through the sliding groove 8 and extends into the inner cavity of the sliding groove 8 to contact the inner wall of the sliding groove 8.

[0042] Specifically, by setting up a servo motor 521, a screw 522, and a moving plate 523, the servo motor 521 provides power, and in conjunction with the screw 522 and the moving plate 523, the moving plate 523 is driven to move, thereby realizing the smooth movement of the support platform 51 and feeding the workpiece.

[0043] By setting the fixing plate 6, the fixing plate 6 plays a role in stabilizing and fixing the servo motor 521.

[0044] By setting slider 7 and slide groove 8, the cooperation between slider 7 and slide groove 8 plays a guiding and limiting role in the movement of moving plate 523, preventing moving plate 523 from deviating or rotating during movement, and ensuring the stability of the movement of bearing platform 51.

[0045] Furthermore, when the moving component 52 is working, the output end of the servo motor 521 drives the screw 522 to rotate after starting. Since the screw 522 is threadedly connected to the moving plate 523, and the moving plate 523 is restricted from rotating through the cooperation of the slider 7 and the slide groove 8, the rotational motion of the screw 522 is converted into the linear motion of the moving plate 523. When the servo motor 521 rotates forward, the screw 522 drives the moving plate 523 to move to the right, thereby driving the two support platforms 51 to move to the right synchronously. When the servo motor 521 rotates in reverse, the moving plate 523 drives the support platform 51 to move to the left. Through the forward and reverse rotation control of the servo motor 521, the two support platforms 51 are alternately switched between the processing area and the material handling area.

[0046] Example 3

[0047] In the second embodiment of this utility model, the positioning component 53 includes a positioning plate 531, a linkage plate 532 is fixedly connected to the middle of the front side of the positioning plate 531, T-shaped blocks 533 are fixedly connected to the left and right sides of the bottom of the linkage plate 532, and a pressing column 534 is fixedly connected to the front side of the bottom of the linkage plate 532.

[0048] The support plate 3 has a travel groove 9 on the front and rear sides of the top, and the bearing platform 51 has a T-shaped groove 10 on both the front and rear sides of the top.

[0049] The two stroke grooves 9 are symmetrically arranged, and the two sides of the inner cavity are inclined and the middle is horizontal. The bottom of the extrusion column 534 passes through the stroke groove 9 and extends into the inner cavity of the stroke groove 9. The bottom of the T-shaped block 533 is located in the inner cavity of the T-shaped groove 10 and contacts the inner wall of the T-shaped groove 10.

[0050] The bottom of the extrusion column 534 is rotatably connected to a bearing 11, and the outer surface of the bearing 11 contacts the inner wall of the stroke groove 9.

[0051] Specifically, by setting the extrusion column 534 and the stroke groove 9, the positioning component 53, through the special shape design of the stroke groove 9, is inclined on both sides and horizontal in the middle, and in conjunction with the movement of the extrusion column 534, realizes the automatic opening and closing of the positioning plate 531;

[0052] By setting T-block 533 and T-slot 10, the cooperation between T-block 533 and T-slot 10 plays a limiting role in the movement of linkage plate 532 and positioning plate 531, ensuring that the opening and closing action of positioning plate 531 is smooth.

[0053] By setting the bearing 11, the bearing 11 at the bottom of the extrusion column 534 converts the sliding friction between the extrusion column 534 and the stroke groove 9 into rolling friction, which reduces component wear, extends service life, and makes the operation of the positioning component 53 smoother.

[0054] Furthermore, when the positioning component 53 is working, when the support table 51 moves under the drive of the moving component 52, the extrusion column 534 moves synchronously with the support table 51, and the bearing 11 at its bottom rolls in the stroke groove 9. When the support table 51 moves towards the processing area, the extrusion column 534 enters the horizontal section from the inclined section of the stroke groove 9. As the inclined sections on both sides of the stroke groove 9 move towards the middle, the extrusion column 534 drives the linkage plate 532 to move towards the center of the support table 51 under the guidance of the inclined section. The T-block 533 slides and guides in the T-groove 10, thereby driving the positioning plate 531 to approach the workpiece and clamp and position it.

[0055] When the support platform 51 moves to the processing area, the extrusion column 534 is in the horizontal section of the stroke groove 9, and the positioning plate 531 remains clamped to ensure the stability of the workpiece position during processing. When the support platform 51 moves out of the processing area, the extrusion column 534 moves from the horizontal section of the stroke groove 9 into the inclined section. The inclined section unfolds outward, and the extrusion column 534 drives the linkage plate 532 and the positioning plate 531 to move outward, releasing the workpiece and making it easier for the operator to pick up and put down the material.

[0056] Working principle:

[0057] The operator places the first workpiece to be processed on top of the left support platform 51. At this time, the left support platform 51 is located in the material handling area, and the positioning components 53 on its front and rear sides are in the open state.

[0058] Then, the servo motor 521 of the moving component 52 is started to rotate forward. The screw 522 drives the moving plate 523 and the two support platforms 51 to move to the right. The left support platform 51 moves towards the processing area. Its extrusion column 534 moves along the inclined section of the stroke groove 9 towards the middle horizontal section. Under the guidance of the inclined section, the linkage plate 532 drives the positioning plate 531 to approach the workpiece and finally clamp and position it. At this time, the extrusion column 534 enters the horizontal section. At the same time, the right support platform 51 moves from the processing area to the material handling area. Its extrusion column 534 moves outward along the inclined section on the other side of the stroke groove 9. The positioning plate 531 gradually opens.

[0059] After the left support platform 51 reaches the processing area, the servo motor 521 stops, and the hydraulic press body 1 drives the mold 2 to press down to process the workpiece on the left. During this period, the operator can place the second workpiece to be processed on the top of the right support platform 51.

[0060] After the workpiece on the left is processed, the mold 2 moves up and resets, the servo motor 521 reverses, and the moving plate 523 drives the two support platforms 51 to move to the left. The left support platform 51 moves towards the material handling area, and its extrusion column 534 moves outward along the inclined section of the stroke groove 9. The positioning plate 531 opens to facilitate the operator to take out the processed workpiece. The right support platform 51 moves towards the processing area, and its positioning component 53 clamps the second workpiece under the guidance of the stroke groove 9.

[0061] After the right-side support platform 51 reaches the processing area, the hydraulic press processes the second workpiece, while the operator simultaneously places a new workpiece on the left-side support platform 51. This cycle repeats to achieve automatic feeding, unloading, and alternating processing between two workstations.

[0062] In summary, by using the support plate 3, rectangular groove 4, and feeding mechanism 5 in combination, automatic feeding and unloading are achieved, improving work safety. At the same time, the dual-station design can improve the continuity of processing.
