Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to a safety protection device for industrial stamping operations. Background Technology

[0002] With the development of the times, my country's industry is also making rapid progress. In industrial manufacturing, stamping is an indispensable process.

[0003] However, the stamping machines widely used in the market today lack corresponding safety protection mechanisms during the stamping maintenance process. This makes it easy for workers to experience continuous downward pressure from the stamping machine, causing unavoidable injuries. This makes the stamping machines extremely unsafe to use and very unfavorable for workers to continue using them.

[0004] As disclosed in announcement number CN217889347U, an industrial stamping operation safety protection device, by installing a protective mechanism, allows the stamping machine to directly stop the pressure plate in mid-air by pulling a lever during the stamping process, preventing further downward pressure. Simultaneously, the safety post at the bottom rises to prevent injury to workers caused by the pressure plate's downward movement, thus better ensuring worker safety and significantly improving the stability of the stamping operation. By installing the stamping mechanism, the stamping machine can perform stamping operations with higher intensity and greater ease during maintenance, while also increasing its sensitivity and self-protection capabilities, preventing injury to workers.

[0005] However, when the device is stamping the workpiece, debris will splash out from the surface of the workpiece, causing injury to the workers, making it less safe.

[0006] Therefore, we urgently need to provide a safety protection device for industrial stamping operations. Utility Model Content

[0007] The purpose of this utility model is to provide a safety protection device for industrial stamping operations, so as to solve the problem mentioned in the background art that when stamping workpieces, debris on the surface of the workpiece will splash out, causing injury to workers and resulting in low safety.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an industrial stamping operation safety protection device, comprising a base plate, a support plate, a lower die, a bracket, a telescopic component, a connecting block, and an upper die. The support plate is fixedly installed on the top of the base plate, the lower die is fixedly installed on the top of the support plate, the bracket is fixedly installed on the back of the base plate, the telescopic component is fixedly installed on the top of the bracket, the connecting block is fixedly installed on the bottom of the telescopic component, the upper die is fixedly installed on the bottom of the connecting block, and a protective device is provided on the top of the base plate. The protective device includes a splash-proof mechanism and a pressure-proof mechanism.

[0009] The splash-proof mechanism is located on the top of the base plate, and the anti-pressure mechanism is located above the base plate.

[0010] The splash-proof mechanism includes a connecting rod, an upper pressure plate, a connecting pipe, a piston rod, a lower pressure plate, a push rod, a connecting plate, and a baffle. The connecting rod is fixedly installed on the left and right sides of the connecting block. The upper pressure plate is fixedly installed on the end of the connecting rod away from the connecting block. The connecting pipe is fixedly installed on the left and right sides inside the support plate. The piston rod is movably installed inside one end of the connecting pipe. The lower pressure plate is fixedly installed on the top of the piston rod. The push rod is movably installed on the other end of the connecting pipe. The connecting plate is fixedly installed on the top of the push rod. The baffle is installed at the bottom of the connecting plate.

[0011] Preferably, the connecting pipe is U-shaped and filled with inert gas. The piston rod and push rod are sealed to the connecting pipe to prevent the inert gas from overflowing.

[0012] Preferably, the lower pressure plate is located above the lower die, and the upper pressure plate is located directly above the lower pressure plate. When the telescopic component pushes the connecting block to move the upper die downward to stamp the workpiece, the upper pressure plate and the lower pressure plate contact first, and as the connecting block moves downward, it squeezes the lower pressure plate, thereby causing the piston rod to move downward. At the same time, the inert gas pushes the push rod to move the connecting plate upward, causing the baffle to unfold upward and block the waste chips splashed out during stamping, thus avoiding injury to the workers.

[0013] Preferably, the contact surfaces of the upper and lower pressure plates are fitted with rubber pads. The weight of the baffle and connecting plate is greater than that of the lower pressure plate and piston rod. After the upper mold moves upward, the connecting plate and baffle will move downward and reset under the action of gravity, thereby facilitating the removal of the workpiece stamped inside the lower mold.

[0014] Preferably, the anti-pressure mechanism includes a fixed rod, a rack, a rotating shaft, a gear, a lever, and a sponge rod. The fixed rod is fixedly installed inside the bracket on the top left side. The rack is fixedly installed at the lower end of the fixed rod. The rotating shaft is rotatably connected to the front of the connecting block. The gear is fixedly installed on the outside of the rotating shaft. The lever is fixedly installed on the outside of the rotating shaft, located on the front of the gear. The sponge rod is fixedly installed on the left side of the lever.

[0015] Preferably, the rack and gear mesh with each other. When the telescopic component pushes the connecting block and the upper mold down to press the workpiece, the gear meshes with the rack, causing the gear to drive the rotating shaft and lever to rotate, causing the sponge rod to rotate clockwise and push the worker's hand away, preventing the worker's hand from being not removed in time and causing crush injury, thus improving the safety of the device.

[0016] Preferably, the sponge rod is located inside the connecting plate to avoid collision between the sponge rod and the connecting plate and the baffle.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This industrial stamping operation safety protection device, through the setting of a splash-proof mechanism, when the telescopic component pushes the connecting block to move the upper die downward to stamp the workpiece, the upper pressure plate and the lower pressure plate first come into contact, and as the connecting block moves downward, it squeezes the lower pressure plate, thereby causing the piston rod to move downward. At the same time, the inert gas pushes the push rod to move the connecting plate upward, causing the baffle to unfold upward, blocking the waste chips splashed out during stamping and avoiding injury to the workers.

[0018] 2. This industrial stamping operation safety protection device, by setting up an anti-pressure mechanism, when the telescopic component pushes the connecting block and the upper die to move down to stamp the workpiece, the gear and rack mesh together, causing the gear to drive the rotating shaft and lever to rotate, causing the sponge rod to rotate clockwise, pushing the worker's hand away, avoiding the worker's hand from being not removed in time and causing crush injury, thus improving the safety of the device.

[0021] 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.

[0022] Example 1: Due to the inherent safety concerns posed by the ejection of debris from the workpiece surface during stamping using current technologies, which can cause injury to workers, please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides a safety protection device for industrial stamping operations, which can block the waste chips splashed during stamping and prevent injury to workers. The industrial stamping operation safety protection device includes a base plate 1, a support plate 2, a lower die 3, a bracket 4, a telescopic component 5, a connecting block 6, and an upper die 7. The support plate 2 is fixedly installed on the top of the base plate 1, the lower die 3 is fixedly installed on the top of the support plate 2, the bracket 4 is fixedly installed on the back of the base plate 1, the telescopic component 5 is fixedly installed on the top of the bracket 4, the telescopic component 5 is a hydraulic cylinder, model HOB160×500, the connecting block 6 is fixedly installed on the bottom of the telescopic component 5, and the upper die 7 is fixedly installed on the bottom of the connecting block 6. A protective device is provided on the top of the base plate 1, which includes a splash-proof mechanism and a pressure-proof mechanism.

[0023] The splash-proof mechanism is located at the top of the base plate 1, and the anti-pressure mechanism is located above the base plate 1.

[0024] The splash-proof mechanism includes a connecting rod 801, an upper pressure plate 802, a connecting pipe 803, a piston rod 804, a lower pressure plate 805, a push rod 806, a connecting plate 807, and a baffle 808. The connecting rod 801 is fixedly installed on the left and right sides of the connecting block 6. The upper pressure plate 802 is fixedly installed at the end of the connecting rod 801 away from the connecting block 6. The connecting pipe 803 is fixedly installed on the left and right sides inside the support plate 2. The connecting pipe 803 is U-shaped and filled with inert gas. The piston rod 804 and the push rod 806 are sealed to the connecting pipe 803 to prevent the inert gas inside the connecting pipe 803 from overflowing. The inert gas is nitrogen. The piston rod 804 is movably installed inside one end of the connecting pipe 803. The lower pressure plate 805 is fixedly installed on the top of the piston rod 804 and is located above the lower mold 3. The upper pressure plate 802 is located directly above the lower pressure plate 805. The telescopic component 5 pushes the connecting block 6 to move... When the upper die 7 moves downward to press the workpiece, the upper pressure plate 802 and the lower pressure plate 805 first come into contact, and as the connecting block 6 moves downward, it squeezes the lower pressure plate 805, thereby causing the piston rod 804 to move downward. At the same time, the inert gas pushes the push rod 806 to move the connecting plate 807 upward, causing the baffle 808 to unfold upward, blocking the waste chips splashed out during the pressing process and preventing injury to the workers. The push rod 806 is movably installed at the other end of the connecting pipe 803, the connecting plate 807 is fixedly installed on the top of the push rod 806, and the baffle 808 is installed at the bottom of the connecting plate 807. The contact surfaces of the upper pressure plate 802 and the lower pressure plate 805 are equipped with rubber pads. The weight of the baffle 808 and the connecting plate 807 is greater than the weight of the lower pressure plate 805 and the piston rod 804. After the upper die 7 moves upward, the connecting plate 807 and the baffle 808 will move downward and reset under the action of gravity, thereby facilitating the removal of the workpiece after it has been pressed inside the lower die 3.

[0025] Example 2: Based on Example 1, please refer to Figures 1-4During the stamping of the workpiece, if the worker's hands are not removed in time, they may be crushed. To prevent this, the device is equipped with an anti-compression mechanism, which includes a fixed rod 901, a rack 902, a rotating shaft 903, a gear 904, a lever 905, and a sponge rod 906. The fixed rod 901 is fixedly installed inside the bracket 4 on the top left side. The rack 902 is fixedly installed at the lower end of the fixed rod 901. The rotating shaft 903 is rotatably connected to the front of the connecting block 6. The gear 904 is fixedly installed on the outside of the rotating shaft 903. The rack 902 and the gear 904 mesh with each other. When the connecting block 6 and the upper mold 7 are pushed down to press the workpiece, the gear 904 meshes with the rack 902, causing the gear 904 to drive the rotating shaft 903 and the lever 905 to rotate, causing the sponge rod 906 to rotate clockwise, pushing the worker's hand away to prevent injury from not removing the hand in time, thus improving the safety of the device. The lever 905 is fixedly installed on the outside of the rotating shaft 903, located on the front of the gear 904. The sponge rod 906 is fixedly installed on the left side of the lever 905, located inside the connecting plate 807, to prevent the sponge rod 906 from colliding with the connecting plate 807 and the baffle 808.

[0026] During use, the workpiece to be stamped is placed into the lower mold 3. Then, the telescopic component 5 is activated to push the connecting block 6, which in turn moves the upper mold 7 downward to stamp the workpiece. As the connecting block 6 and the upper mold 7 move downward, the gear 904 meshes with the rack 902, causing the gear 904 to drive the rotating shaft 903 and the lever 905 to rotate, making the sponge rod 906 rotate clockwise to push the worker's hands away, preventing them from being crushed if not removed in time. When the upper pressure plate 802 contacts the lower pressure plate 805, the lower pressure plate 805 is squeezed as the connecting block 6 moves downward, causing the piston rod 804 to move downward. At the same time, the inert gas pushes the push rod 806, which moves the connecting plate 807 upward, causing the baffle 808 to unfold upward and block the waste chips splashed out during stamping, preventing injury to the worker.
