They are suitable for a variety of cold stamping processes, including shearing, blanking, punching, bending, and shallow drawing, and are widely used across various industrial manufacturing sectors.

[0003] Because the open fixed-table press has an open structure, waste chips are very likely to fly during the above-mentioned stamping operation; at the same time, the open fixed-table press may also cause the stamping die to explode when working, causing the stamping die punch or parts to break out under the action of the punch press; the flying waste chips and the broken die punch or parts are very likely to cause work-related accidents, posing a huge safety hazard. Summary of the Invention

DETAILED DESCRIPTION

[0026] Below in conjunction with the appended Figures 1 to 7 , the technical solutions in the embodiments of the present invention are clearly and completely described, but the protection scope of the present invention is not limited to the following.

[0027] Example 1

[0028] An open fixed table press, such as Figure 6 As shown, it includes a workbench 100 and a press body 110 arranged on the workbench 100; in addition, as shown Figure 1-4 As shown, the open fixed table press also includes a U-shaped waste trough 120 arranged around the outer wall of the workbench 100, a baffle arranged inside the waste trough 120, and a driving mechanism capable of driving the baffle to perform vertical displacement; the baffle includes two parallel first baffles 130, and a second baffle 140 arranged between the two first baffles 130 and perpendicular to the two first baffles 130; the two first baffles 130 can be moved away from or close to the second baffle 140 respectively by a first moving device; the second baffle 140 can be moved away from the workbench 100 by a second moving device; the second baffle 140 is a transparent plate for easy observation.

[0029] In the above solution, by providing a waste chute 120, waste on the workbench 100 can be collected to prevent waste from being scattered on the ground; by providing a baffle in the waste chute 120, waste chips and broken parts generated during the operation of the press body can be protected to prevent them from causing harm to the workers; by providing a driving mechanism, the baffle can be moved in the vertical direction so that the baffle can protect the workbench 100 when working, and when not working, the baffle is moved down into the waste chute 120 to achieve the storage of the baffle, thereby preventing the baffle from blocking the transportation or removal of the workpiece;

[0030] Waste chips with large volume or mass, as well as popped-out parts or punches, will generate a large impact force. Simply relying on a baffle that can only move in the vertical direction is difficult to buffer the strong impact force in the horizontal direction, which will cause the protective plate to be easily broken and lead to protection failure. At the same time, even if the baffle is not damaged, the above-mentioned waste chips or parts and other flying materials will rush towards the baffle and rebound back to the workbench 100 with a large force, causing damage to other equipment on the workbench 100, making it difficult to proceed with the stamping work smoothly, and also causing great losses.

[0031] In order to overcome the above technical defects, the present invention further defines the structure of the baffle, including two parallel first baffles 130 and a second baffle 140 arranged between the two first baffles 130. By providing a first moving device, when large-volume or heavy waste chips or broken parts are splashed onto the first baffle 130, the first baffle 130 can move the rod in the direction away from the second baffle 140 to achieve buffering of the splashing materials, thereby reducing the impact force of the splashing materials rebounding and reducing its impact on the equipment on the workbench 100. At the same time, under the buffering effect of the first moving device, the impact force of the splashing materials on the first baffle 130 can be reduced, thereby extending the service life of the first baffle 130; when the splashing materials splash onto the second baffle 140, the first and second baffles are moved forward to achieve buffering of the splashing materials, thereby reducing the impact force of the splashing materials rebounding and reducing its impact on the equipment on the workbench 100. At the same time, through the shock-absorbing and buffering effect of the second moving device, the impact force of the splashing materials on the second baffle 140 can be reduced, thereby extending the service life of the second baffle 140. Through the coordinated action of the above-mentioned devices, the impact force on the baffle and the rebound force of the splashing materials after rushing towards the baffle can be reduced, thereby extending the service life of the baffle and various equipment on the workbench 100.

[0032] Further, such as Figure 1-7 As shown, the drive mechanism includes a vertical rail 150 disposed within the waste chute 120, and a slider 160 disposed at the end of the first baffle 130 away from the second baffle 140 and slidably engaged with the vertical rail 150. The top end of the vertical rail 150 extends outside the waste chute 120. The vertical rail 150 is an electric rail. In this embodiment, when the baffle needs to be moved, the electric rail is electrically connected to a power source. Thereafter, the slider 160 moves up and down on the surface of the vertical rail 150, thereby moving the baffle in the vertical direction, thereby achieving the purpose of automated movement.

[0033] Furthermore, the first moving device includes two first grooves 170 arranged on the contact surface of the first baffle 130 and the second baffle 140, a connecting block 180 arranged between the first baffle 130 and the slider 160, two second grooves 190 arranged on the contact surface of the first baffle 130 and the connecting block 180, a first shock absorber 200 arranged in the two first grooves 170, and a second shock absorber 210 arranged in the two second grooves 190; the two end portions of the first shock absorber 200 are respectively fixedly connected to the sides of the two first grooves 170 away from each other; the two end portions of the second shock absorber 210 are respectively fixedly connected to the sides of the two second grooves 190 away from each other; the length directions of the first shock absorber 200 and the second shock absorber 210 are both parallel to the second baffle 140; the two first grooves 170 are respectively arranged on the two surfaces of the first and second baffles in contact with each other; the second grooves 190 are respectively arranged on the two surfaces of the first baffle 130 and the connecting block 180 in contact with each other.

[0034] In the above solution, the structure of the first moving device is further defined. By providing the first groove 170, the first shock absorber 200, the second groove 190 and the second shock absorber 210, when large-volume or heavy waste or broken parts splash onto the first baffle 130, the first shock absorber 200 and the second shock absorber 210 on the left or right side are synchronously extended (e.g., Figure 3 As shown), the first shock absorber 200 and the second shock absorber 210 can reduce the impact of the splashing material on the first baffle 130, thereby reducing the impact of the splashing material rebounding and reducing its impact on the equipment on the workbench 100. At the same time, under the buffering effect of the first shock absorber 200 and the second shock absorber 210, the impact of the splashing material on the first baffle 130 can be reduced, thereby extending the service life of the first baffle 130.

[0035] Furthermore, the second moving device includes two third grooves 220 provided on the contact surface between the connecting block 180 and the slider 160, and a third shock absorber 230 provided in the two third grooves 220 (wherein the first, second and third shock absorbers are all prior art and their working principles are not described in detail here); the two ends of the third shock absorber 230 are respectively fixedly connected to the sides of the two third grooves 220 that are away from each other; the two third grooves 220 are respectively provided on the two contact surfaces between the connecting block 180 and the slider 160. In this solution, the structure of the second moving device is further defined. When the splashing material splashes onto the second baffle 140, the third shock absorber 230 extends (such as Figure 4As shown), the first and second baffles, the slider 160 and the connecting block 180 move synchronously with the extension of the third shock absorber 230 to achieve buffering of the splashing materials, thereby reducing the impact force of the splashing materials rebounding and reducing their impact on the equipment on the workbench 100. At the same time, through the shock-absorbing effect of the third shock absorber 230, the impact force of the splashing materials on the second baffle 140 can be reduced, thereby extending the service life of the second baffle 140.

[0036] Specific implementation principle of embodiment 1: first place the workpiece on the workbench 100. The equipment on the workbench 100 can be selected according to the actual operation, such as a punch, etc., which is not limited here. Then turn on the power supply electrically connected to the vertical slide rail 150.

[0037] Afterwards, the slider 160 moves upward in the vertical slide rail 150. During the movement, it drives the first and second baffles and the connecting block 180 to move upward until the workbench 100 is covered. Afterwards, the press body 110 is opened (this is the existing technology, and its working principle will not be described in detail here) to process the workpiece. During the processing, the waste generated splashes onto the baffle, which is blocked to prevent the splashed waste from splashing and injuring the workers. After being blocked by the baffle, the splashed waste falls into the waste box for collection. When some parts with large volume or mass and on the workbench 100 collapse, they will cause a great impact on the baffle. When these splashed materials splash onto the inner wall of the first baffle 130, the first shock absorber 200 and the second shock absorber 210 on the left or right side extend synchronously, such as Figure 3 As shown, the first and second dampers 200 and 210 can cushion the impact of the splashing material on the first baffle 130, thereby reducing the impact force of the splashing material when it rebounds, and reducing the adverse impact of the splashing material rebounding onto the workbench 100 on the equipment on the workbench 100. At the same time, under the cushioning effect of the first and second dampers 200 and 210, the impact force of the splashing material on the first baffle 130 can be reduced, thereby extending the service life of the first baffle 130. When the splashing material splashes onto the second baffle 140, the third damper 230 is extended, so that the first and second baffles, the slider 160, and the connecting block 180 move toward the front side of the workbench 100 synchronously with the extension of the third damper 230, thereby cushioning the splashing material, thereby reducing the impact force of the splashing material rebounding, and reducing the adverse impact of the splashing material rebounding onto the workbench 100 on the equipment on the workbench 100. At the same time, the damping effect of the third damper 230 can reduce the impact force of the splashing material on the second baffle 140, thereby extending the service life of the second baffle 140. During the operation of the press body 110 , the worker can observe the operation status on the workbench 100 through the second baffle 140 .

[0038] On the basis of Example 1, Figure 1-4 and Figure 7As shown, the open fixed table press also includes a first connecting cloth 240, which is simultaneously provided on the first baffle 130 and the second baffle 140 and is used to connect the first baffle 130 and the second baffle 140, and a second connecting cloth 250, which is simultaneously provided on the first baffle 130 and the connecting block 180 and is used to connect the first baffle 130 and the connecting block 180. In Example 1, when the first baffle 130 is displaced horizontally, gaps will appear between the first baffle 130 and the second baffle 140 and between the first baffle 130 and the connecting block 180, causing waste generated during the stamping process to diffuse along the gaps. In particular, during powder metallurgy stamping operations, the generated powder waste will diffuse into the air along the gaps. In this solution, by providing the first and second connecting cloths, they can adaptively deform as the first baffle 130 moves, ensuring that the gaps are blocked and preventing waste from splashing or diffusing through the gaps.

[0039] Furthermore, in Example 1, when the third shock absorber 230 is extended, a gap will appear between the connecting block 180 and the slider 160, causing the waste generated during the stamping process to spread along the gap, causing environmental pollution. In order to overcome this technical defect, as Figure 1-4 and Figure 7 As shown, the open fixed-table press further includes a third connecting fabric 280 disposed on both the connecting block 180 and the slider 160 and used to connect the connecting block 180 and the slider 160. In this embodiment, the third connecting fabric 280 adaptively deforms as the connecting block 180 moves, ensuring that the gap between the slider 160 and the connecting block 180 is always covered, preventing waste from splashing along the gap.

[0040] Furthermore, when the baffle is working, the distance between it and the top wall of the waste tank 120 is relatively close, causing the powder waste to diffuse to the outside along the gap between the two, causing environmental pollution. In order to overcome this technical defect, as Figure 1-4 and Figure 7As shown, a sidewall of the waste trough 120, away from the workbench 100, is surrounded by an elastic fabric 260. The end of the elastic fabric 260, away from the waste trough 120, is connected to the first baffle 130, the second baffle 140, and the bottom end of the first connecting fabric 240, respectively. In this embodiment, the elastic fabric 260 maintains contact with the baffles during their upward and downward movement, thereby preventing powder waste from dispersing into the air through the gaps between the baffles during operation. Furthermore, the elasticity of the elastic fabric 260 allows it to elastically expand and contract to accommodate the displacement of the first and second baffles. Because the overall expansion and contraction range of the first, second, and third dampers in the present invention is relatively small, the elastic fabric 260 is also stretched to a smaller extent, and the pores within the elastic fabric 260 are also stretched to a smaller extent, effectively reducing the dispersion of powder waste from the pores of the elastic fabric 260. In addition, the end of the elastic cloth 260 away from the waste box is not completely connected to the baffle, but is partially connected to the bottom end of the first connecting cloth 240. This allows the waste debris splashed onto the second connecting cloth 250 to fall to the bottom of the waste box under the action of gravity, so as to facilitate the recovery of the waste. This effectively overcomes the defect that the end of the elastic cloth 260 away from the waste box is completely connected to the baffle, causing the waste on the first connecting cloth 240 to fall into the elastic cloth 260, resulting in it not being able to fall directly to the bottom of the waste box for recycling.

[0041] Further, such as Figure 1-4 As shown, a scraper 270 is provided on the side of the second baffle 140 close to the workbench 100. The scraper 270 is connected to the center of the second baffle 140 via a connecting seat (not shown in the figure). The scraper 270 can rotate with the connecting seat as the rotation axis. During actual operation, the second baffle 140 is also provided with a driving device for driving the connecting seat to rotate. For example, a motor can be provided on the side of the second baffle 140 away from the workbench 100, and the output end of the motor is connected to the connecting seat. In this way, the rotation of the scraper 270 can be achieved. In this solution, by rotating the scraper, waste materials splashed onto the second baffle 140 can be scraped off to prevent the waste materials from blocking the workers' vision and making it difficult to see the work progress on the workbench 100 in a timely manner.
