Description

Technical Field

[0001] This utility model relates to the technical field of floor joint stamping equipment, specifically a continuous stamping forming mold for floor joints. Background Technology

[0002] Grounding plates are core components for grounding protection in electrical systems, electronic equipment, and industrial facilities. Their function is to provide a safe discharge path for current, preventing damage to personnel and equipment from electric shock, electromagnetic interference, or lightning strikes. Equipment casings can be connected to the earth using grounding plates, ensuring that leakage current flows directly to the ground through the grounding plate, thus avoiding electric shock to personnel.

[0003] In the existing technology, in order to facilitate the installation of grounding plates, it is usually necessary to punch holes in the grounding plates during production. This can be used to install bolts, rivets or expansion anchors. However, after the punching is completed, the grounding plates need to be manually removed from the mold. When manually removing the parts, it is necessary to get close to the mold, which poses a serious risk of workplace accidents such as being pinched or scratched by the mold, and it also affects the processing efficiency. Therefore, a continuous punching forming mold for grounding plates is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous stamping die for the bonding plate, so as to solve the problem mentioned in the background art that after the bonding plate is stamped, it is necessary to manually remove the bonding plate from the die. When manually removing the part, it is necessary to get close to the die, which poses a serious risk of workplace injury such as being pinched or scratched by the die, and also affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous stamping forming die for a grounding plate, comprising a stamping machine, a die frame provided on the stamping machine, an upper die and a lower die provided inside the die frame; two support frames are symmetrically installed on the die frame, a conveying structure is connected to the two support frames, a fixing screw and a fixing rod are connected to the die frame, a pressing structure is connected to the fixing screw, a reset structure is connected to the fixing rod, and a sliding hole is opened in the corresponding support frame, with an adaptation structure connected in the sliding hole.

[0006] Preferably, the conveying structure includes a dual-axis motor, which is mounted on the inner wall of the corresponding support frame. Both output ends of the dual-axis motor are equipped with a first transmission wheel. A limit strip is slidably installed inside the sliding hole. A second transmission wheel is rotatably installed on both sides of the limit strip. The first and second transmission wheels on the same side are connected to the same conveyor belt. The two conveyor belts are movably mounted with the same grounding plate.

[0007] Preferably, four positioning plates are symmetrically installed inside the mold frame, and the four positioning plates are respectively located on the two conveyor belts on opposite sides.

[0008] Preferably, the pressing structure includes a T-shaped pressure rod, which is slidably sleeved on the fixed screw.

[0009] Preferably, the fixing screw is threaded with two nuts, which respectively contact the two sides of the T-shaped pressure rod.

[0010] Preferably, the adaptive structure includes a plurality of guide rods, the two ends of which are respectively installed on the inner walls of the two sides of the sliding hole. A limiting slide is slidably sleeved on the guide rod. A spring is slidably sleeved on the guide rod. One end of the spring is installed on one side of the limiting slide, and the other end of the spring is installed on the inner wall of the sliding hole.

[0011] Preferably, the reset structure includes an L-shaped connecting plate, which is slidably sleeved on a fixed rod. Two support wheels are rotatably installed on one side of the L-shaped connecting plate, and both support wheels are in contact with the corresponding conveyor belts. A second spring is slidably sleeved on the fixed rod, and the two ends of the second spring are respectively installed between the mold frame and the L-shaped connecting plate.

[0012] Preferably, a stop is installed at one end of the fixing rod, and the stop contacts the top of the L-shaped connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In use, the base plate can be placed on the conveyor belts on both sides. By turning on the dual-axis motor, the base plate can be conveyed to the top of the lower mold. Then, the dual-axis motor is stopped and the mold frame is controlled to merge using the stamping machine. During the process, the upper mold and T-shaped pressure bar will be driven to descend. The T-shaped pressure bar will press on the base plate first and cause the conveyor belt to be deformed by pressure. At the same time, it will squeeze the support wheel and drive the L-shaped connecting plate to descend. After that, the descending upper mold will perform a stamping operation on the base plate. After the stamping is completed, the mold frame is opened under control. At this time, under the action of the second spring, the support wheel will push the base plate to rise and demold, which facilitates the quick demolding of the base plate, saves the time of manual part removal, and thus improves production efficiency.

[0015] (2) When the conveyor belt is squeezed, it will drive the second transmission wheel and the limit slide to slide. The limit slide will compress the first spring. When the conveyor belt is no longer squeezed, the first spring will reset and drive the limit slide and the second transmission wheel to reset, thereby re-opening the conveyor belt and resetting it. This allows the conveyor belt to adapt to the degree of pressure. At the same time as the conveyor belt recovers, the support wheel will also push the mating plate out of the mold. At this time, the dual-shaft motor can be driven again to use the conveyor belt to transport the stamped mating plate, which is convenient for quick unloading. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a continuous stamping forming die for a grounding plate, including a stamping machine 100, a die frame 101 on the stamping machine 100, an upper die 102 and a lower die 103 inside the die frame 101; two support frames 200 are symmetrically installed on the die frame 101, and a conveying structure is connected to the two support frames 200. The conveying structure is used to convey the workpiece to the upper die 103 for stamping. A fixing screw 300 and a fixing rod 500 are connected to the die frame 101. A pressing structure is connected to the fixing screw 300. The pressing structure is used to follow the descent of the upper die 102 and press the conveying structure to ensure that the workpiece can fall into the lower die 103. A reset structure is connected to the fixing rod 500. After stamping is completed, the finished part can be ejected from the die by the reset structure. A sliding hole 400 is opened in the corresponding support frame 200. An adaptation structure is connected in the sliding hole 400. When the conveying structure is squeezed, the adaptation structure can make the conveying structure move with the squeezing force.

[0024] Furthermore, the conveying structure includes a dual-axis motor 201, which is mounted on the inner wall of the corresponding support frame 200. Both output ends of the dual-axis motor 201 are equipped with a first transmission wheel 202. A limiting slide bar 203 is slidably installed inside the sliding hole 400. A second transmission wheel 204 is rotatably mounted on both sides of the limiting slide bar 203. The same conveyor belt 205 is driven and mounted on the first and second transmission wheels 204 on the same side. The same grounding plate 206 is movably mounted on both conveyor belts 205. By turning on the dual-axis motor 201, the first transmission wheel 202 can be driven to rotate. When the first transmission wheel 202 rotates, it can drive the second transmission wheel 204 to move in a circular motion through the transmission cooperation between the second transmission wheel 204 and the conveyor belt 205, thereby moving the placed grounding plate 206.

[0025] Furthermore, four positioning plates 207 are symmetrically installed inside the mold frame 101. The four positioning plates 207 are located on opposite sides of the two conveyor belts 205. The ground plate 206 is placed on the two conveyor belts 205, so that it is positioned between the two positioning plates 207. The positioning plates 207 are used to guide the ground plate 206.

[0026] Furthermore, the pressing structure includes a T-shaped pressure bar 301, which is slidably sleeved on the fixed screw 300. By using the press 100 to control the mold frame 101 to merge, the upper mold 102 and the fixed screws 300 on both sides can be driven to descend, thereby driving the T-shaped pressure bar 301 to descend and press on the ground plate 206. The ground plate 206 will squeeze the conveyor belt 205 and move downward.

[0027] Furthermore, two nuts 302 are threaded onto the fixing screw 300. The two nuts 302 are in contact with both sides of the T-shaped pressure rod 301. By rotating the nuts 302, they can be moved on the fixing screw 300 and disengaged from the T-shaped pressure rod 301, thereby releasing the restriction on the T-shaped pressure rod 301. The height of the T-shaped pressure rod 301 can be adjusted by pushing it up and down, and the downward pressing distance of the T-shaped pressure rod 301 can be adjusted.

[0028] Furthermore, the adaptive structure includes several guide rods 401, with both ends of the guide rods 401 respectively installed on the inner walls of the sliding holes 400 on both sides. A limiting slide bar 203 is slidably sleeved on the guide rods 401, and a spring 402 is slidably sleeved on the guide rods 401. One end of the spring 402 is installed on one side of the limiting slide bar 203, and the other end of the spring 402 is installed on the inner wall of the sliding holes 400. When the conveyor belt 205 is compressed, it will drive the transmission wheel 204 to move in the direction of the dual-axis motor 201. The transmission wheel 204 can drive the limiting slide bar 203 to slide in the sliding holes 400. At the same time, the limiting slide bar 203 will slide on the guide rods 401 and compress the spring 402, so that the conveyor belt 205 can move and adapt according to the degree of downward pressure of the T-shaped pressure bar 301.

[0029] Example 2: As Figure 2-5 To facilitate the ejection and demolding of the contact plate 206 from the lower mold 103, a reset structure is provided. The reset structure includes an L-shaped connecting plate 501, which is slidably mounted on a fixed rod 500. Two support wheels 502 are rotatably mounted on one side of the L-shaped connecting plate 501, and both support wheels 502 are in contact with the corresponding conveyor belts 205. A second spring 503 is slidably mounted on the fixed rod 500, with its two ends respectively installed between the mold frame 101 and the L-shaped connecting plate 501. When the contact plate 206 descends, it will compress the conveyor belt 205 and the support wheels 502. 2. The support wheel 502 drives the L-shaped connecting plate 501 to slide on the fixed rod 500 and compress the second spring 503. After the stamping is completed and the control mold frame 101 is unfolded, the compressed second spring 503 will push the L-shaped connecting plate 501 and the support wheel 502 to rise and reset, push the ground plate 206 and push it out of the lower mold 103 for demolding. A stop block 504 is installed at one end of the fixed rod 500. The stop block 504 contacts the upper part of the L-shaped connecting plate 501. The setting of the stop block 504 can prevent the L-shaped connecting plate 501 from loosening from the fixed rod 500. The other features are the same as in embodiment 1.

[0030] The working principle is as follows: During use, the mounting plate 206 is placed on two conveyor belts 205. Turning on the dual-axis motor 201 drives the corresponding transmission wheel 202 to rotate. When the transmission wheel 202 rotates, it drives the transmission wheel 204 to rotate circumferentially through the transmission cooperation between the transmission wheel 204 and the conveyor belts 205. This, in turn, moves the mounting plate 206. When the mounting plate 206 moves above the lower mold 103, both ends of the mounting plate 206 will be positioned above the L-shaped connecting plates 501 on both sides. The dual-axis motor 201 is then stopped, and the stamping machine 100 controls the mold... The frame 101 is assembled, which in turn drives the upper mold 102 and the fixing screws 300 on both sides to descend. The descending fixing screws 300 can drive the T-shaped pressure rods 301 to descend through the nuts 302, so that the ends of the T-shaped pressure rods 301 on both sides will press against the two ends of the ground plate 206. The ground plate 206 will squeeze the conveyor belt 205 and the support wheel 502, causing the support wheel 502 to drive the L-shaped connecting plate 501 to slide on the fixing rod 500 and compress the second spring 503. The squeezed conveyor belt 205 will then drive the second transmission wheel 204 to move in the direction of the dual-shaft motor 201. The second 204 can drive the limiting slide bar 203 to slide within the sliding hole 400. At the same time, the limiting slide bar 203 will slide on the guide rod 401 and compress the first spring 402, so that the conveyor belt 205 can move and adapt according to the downward pressure of the T-shaped pressure bar 301. Finally, the ground platen 206 will be pressed onto the lower mold 103, and the upper mold 102 will continue to descend and perform a stamping operation on the ground platen 206. After the stamping is completed, the mold frame 101 can be controlled to unfold and drive the upper mold 102 and the fixing screw 300 to rise and reset. At this time, the compressed first spring 402 will push the limiting slide bar 203 to move within the sliding hole 400. 03. Movement reset causes the limit slider 203 to drive the transmission wheel 204 to reset and the conveyor belt 205 to return to normal. At the same time, the compressed spring 503 pushes the L-shaped connecting plate 501 to rise and reset. The L-shaped connecting plate 501 then drives the support wheel 502 to rise and reset. Under the restoring action of the conveyor belt 205 and the reset movement of the support wheel 502, the base plate 206 can be pushed up and pushed out of the lower mold 103. At this time, the dual-axis motor 201 can be driven again to control the conveyor belt 205 to move again and transport the stamped base plate 206.
