Description

Technical Field

[0001] This utility model belongs to the field of commemorative medal processing technology, and in particular relates to a pressing device for commemorative medal design. Background Technology

[0002] The edge pressing device for commemorative medal design is a special equipment used to process specific patterns, engravings or decorative structures on the edge of commemorative medals (or badges, coins, etc.). Its core function is to shape or engrave the edge of the metal blank through mechanical pressure to enhance the overall aesthetics and craftsmanship value of the commemorative medal.

[0003] Existing edge-pressing devices require manual adjustment of the clamping device by workers to hold and fix the commemorative medal during operation. However, this method requires frequent adjustment of the clamping device during the production process, which increases the workload of workers. At the same time, unstable manual clamping can easily cause uneven edge pressing, resulting in substandard edge pressing quality of the commemorative medal body. Therefore, we propose an edge-pressing device for commemorative medal design. Utility Model Content

[0004] The purpose of this invention is to provide a pressing device for commemorative medal design. Specifically, by activating a fixed part, an electric push rod retracts, causing its top output end to move a lifting block downwards. The three inclined surfaces on the outer side of the lifting block press against the sides of three clamping columns that are close to each other, causing the clamping columns to move away from each other. Since the clamping block and the fixed frame are rotatably connected by a pin, when the rounded end of the clamping column pushes the clamping block, the clamping block rotates counterclockwise around the pin axis, causing its top ends to move closer together, thereby clamping and fixing the outer ring of the commemorative medal. This method can quickly clamp and fix the commemorative medal, while also positioning it to prevent displacement and damage during the pressing process. It solves the problem that existing pressing devices require manual adjustment of the clamping device, leading to reduced production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pressing device for commemorative medal design, comprising a pressing machine, an edge pressing table installed inside the pressing machine, a pressing table installed on top of the worktable, a commemorative medal installed above the pressing table, and a punch installed inside the pressing machine, and further comprising:

[0007] A fixing part, said fixing part being installed on the outer ring of the pressing table, said fixing part being used to fix the commemorative medal; and

[0008] The unloading section is installed inside the pressing table and is used to unload the commemorative medals.

[0009] The fixing part can position the commemorative medal so that its center coincides with the center of the pressing platform.

[0010] Furthermore, the fixing part includes three clamping blocks, and the outer ring of the pressing table is fixedly connected to three fixing frames;

[0011] A movable component is mounted on the bottom of the pressing table and is used to drive the fixed part to operate;

[0012] A clamping assembly is mounted on the outer ring of the pressing table and is used to clamp commemorative medals;

[0013] The clamping block is rotatably connected to the fixing frame via a pin, and a serrated rubber pad is installed on the top of the clamping block near the medal to increase friction.

[0014] Furthermore, the unloading section includes a pressing seat, which is installed on the top of the pressing table and is used to press the outer edge of the commemorative medal.

[0015] A die, which is installed inside the pressure seat, is used to support the commemorative medal;

[0016] The pressure seat is cylindrical, and the die is slidably limited to the inner wall of the pressure seat. The bottom of the die is trapezoidal to prevent the die from detaching from the pressure seat.

[0017] Furthermore, the moving component includes an electric push rod, the bottom of which is fixedly connected to the top of the worktable by bolts, and a lifting block is fixedly connected to the top output end of the electric push rod by bolts;

[0018] The workbench and pressing table are provided with lifting grooves inside. The outer ring of the lifting block is slidably limited to the inner wall of the lifting groove. The outer ring of the lifting block is provided with three inclined surfaces.

[0019] Furthermore, the clamping assembly includes three clamping posts, and the pressing table has three circular grooves inside, with the clamping posts slidingly limiting the engagement with the circular grooves.

[0020] The clamping column is spherical on the side near the clamping block, and inclined on the side near the lifting block.

[0021] Furthermore, the pressing table has three circular grooves inside, each with a limiting groove inside. An expansion column is slidably limited inside the circular groove, and two limiting protrusions are fixedly connected to the outer ring of the expansion column. The expansion column is slidably limited to the limiting groove through the two limiting protrusions.

[0022] The limiting groove is used to prevent the expansion column from disengaging from the second circular groove. A spring is fixedly connected to the inner wall of the second circular groove. The other end of the spring is fixedly connected to the side of the expansion column away from the clamping block. The side of the expansion column near the clamping block is spherical.

[0023] Furthermore, the unloading part includes a fixed circular plate, the bottom of which is fixedly connected to the bottom of the inner wall of the pressure seat, and several springs are fixedly connected to the bottom of the inner wall of the pressure seat. A lifting column is fixedly connected to the top of the lifting block, and an unloading hole is opened inside the die. The lifting column slides through the pressure table and the die.

[0024] The top end of the second spring is fixedly connected to the bottom of the die, and the second spring is used to push the die to reset.

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model, by setting a fixing part, specifically involves activating an electric push rod to retract, whose top output end drives the lifting block to move downwards. The three inclined surfaces on the outer side of the lifting block press against the side of the three clamping columns that are close to each other, causing the clamping columns to move away from each other. Since the clamping block and the fixing frame are rotatably connected by a pin, when the round end of the clamping column pushes the clamping block, the clamping block rotates counterclockwise around the pin axis, and its top ends move closer to each other, thereby clamping and fixing the outer ring of the commemorative medal. This method can quickly clamp and fix the commemorative medal, and at the same time, it can position the commemorative medal to prevent it from shifting and causing damage during the pressing process.

[0027] 2. This utility model, by setting up an unloading section, specifically involves starting the pressing machine to move the punch upwards, and spring two pushing the die and commemorative medal back to their original positions through elastic force. At the same time, the electric push rod extends, pushing the lifting block upwards from the top. Spring one pushes the expansion column to expand with each other, and its rounded end causes the clamping block to rotate clockwise around the pin. The lifting block pushes the commemorative medal upwards through the top lifting column, preventing it from getting stuck in the pressing seat. This method, through the cooperation of several springs two and lifting columns, can quickly unload the commemorative medal, eliminating the need for workers to use tools for unloading and greatly improving processing efficiency.

[0028] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-6As shown, this utility model is a pressing device for commemorative medal design, including a pressing machine 1, a worktable 11 installed inside the pressing machine 1, a pressing table 12 installed on the top of the worktable 11, a commemorative medal 13 installed above the pressing table 12, a punch 14 installed inside the pressing machine 1, and also includes: a fixing part 2, which is installed on the outer ring of the pressing table 12 and is used to fix the commemorative medal 13; and an unloading part 3, which is installed inside the pressing table 12 and is used to unload the commemorative medal 13; wherein, the fixing part 2 can position the commemorative medal 13 so that its center coincides with the center of the pressing table 12. The fixing part 2 includes three clamping blocks 222, and three fixing frames 221 are fixedly connected to the outer ring of the pressing table 12; a moving component 21 is installed at the bottom of the pressing table 12 and is used to drive the fixing part 2 to work; a clamping component 22 is installed on the outer ring of the pressing table 12 and is used to clamp the commemorative medal 13; wherein, the clamping block 222 is rotatably connected to the fixing frame 221 by a pin, and a serrated rubber pad is installed on the top of the clamping block 222 near the commemorative medal 13 to increase the friction. The unloading section 3 includes a pressing seat 32, which is installed on the top of the pressing table 12 and is used to press the outer edge of the commemorative medal 13; and a die 33, which is installed inside the pressing seat 32 and is used to support the commemorative medal 13. The pressing seat 32 is cylindrical, and the die 33 slides and is limited to the inner wall of the pressing seat 32. The bottom of the die 33 is trapezoidal to prevent it from detaching from the pressing seat 32. The moving component 21 includes an electric push rod 211, the bottom of which is fixedly connected to the top of the worktable 11 by bolts. The top output end of the electric push rod 211 is fixedly connected to a lifting block 212 by bolts. The worktable 11 and the pressing table 12 have lifting grooves inside, and the outer ring of the lifting block 212 slides and is limited to the inner wall of the lifting groove. The outer ring of the lifting block 212 has three inclined surfaces. The clamping assembly 22 includes three clamping posts 224. The pressing table 12 has three circular grooves 223 inside. The clamping posts 224 slide and limit the engagement with the circular grooves 223. The side of the clamping post 224 near the clamping block 222 is spherical, and the side of the clamping post 224 near the lifting block 212 is inclined.The pressing table 12 has three circular grooves 225 inside. Each circular groove 225 has a limiting groove 228 inside. An expansion column 226 is slidably limited within the circular groove 225. Two limiting protrusions 227 are fixedly connected to the outer ring of the expansion column 226. The expansion column 226 is slidably limited by the two limiting protrusions 227 and the limiting groove 228. When the electric push rod 211 is activated to retract, its top output end drives the lifting block 212 to move downwards. The three inclined surfaces on the outer side of the lifting block 212 press against the side of the three clamping columns 224 that are close to each other, causing the clamping columns 224 to move away from each other. Because the clamping block 222 and the fixing frame 221 are rotatably connected by a pin, when the clamping columns 224... When the round end pushes the clamping block 222, the clamping block 222 rotates counterclockwise around the pin axis, and the top ends of the two blocks come closer to each other, thereby clamping and fixing the outer ring of the commemorative medal 13. This method can quickly clamp and fix the commemorative medal 13, and at the same time, it can position the commemorative medal 13 to prevent it from shifting and causing damage during the pressing process. The limiting groove 228 is used to prevent the expansion column 226 from disengaging from the circular groove 225. The inner wall of the circular groove 225 is fixedly connected to the spring 229. The other end of the spring 229 is fixedly connected to the side of the expansion column 226 away from the clamping block 222. The side of the expansion column 226 near the clamping block 222 is spherical. The unloading section 3 includes a fixed circular plate 34, the bottom of which is fixedly connected to the bottom of the inner wall of the pressing seat 32. Several springs 35 are fixedly connected to the bottom of the inner wall of the pressing seat 32. A lifting column 31 is fixedly connected to the top of the lifting block 212. An unloading hole 36 is opened inside the die 33. The lifting column 31 slides through the pressing table 12 and the die 33. When the pressing machine 1 is started, the punch 14 moves upward. The springs 35 push the die 33 and the medal 13 back to their original positions through elastic force. At the same time, the electric push rod 211 extends and pushes the lifting block 212 upward. 9. The expansion columns 226 expand with each other, and their round ends cause the clamping block 222 to rotate clockwise around the pin. The lifting block 212 pushes the commemorative medal 13 upward through the top lifting column 31 to prevent it from getting stuck in the pressure seat 32. This method, through the cooperation of several springs 35 and the lifting column 31, can quickly unload the commemorative medal 13 without the need for workers to use tools for unloading, which greatly improves the processing efficiency. Among them, the top end of the spring 35 is fixedly connected to the bottom of the die 33, and the spring 35 is used to push the die 33 to reset.

[0040] A specific application of this embodiment is as follows: When in use, the commemorative medal 13 is placed on the top of the pressing table 12, and then the electric push rod 211 is activated to retract. The top output end of the electric push rod 211 drives the lifting block 212 to move downward. The three inclined surfaces on its outer side will simultaneously squeeze the side of the three clamping columns 224 that are close to each other, so that the three clamping columns 224 move away from each other. Since the clamping block 222 and the fixing frame 221 are rotatably connected by a pin, when one end of the round head of the clamping column 224 pushes the clamping block 222, it will rotate counterclockwise around the pin axis. At this time, the top ends of the three clamping blocks 222 will move closer to each other to clamp and fix the outer ring of the commemorative medal 13. A serrated rubber pad is installed on the side of the clamping block 222 that is close to the commemorative medal 13, which can increase the friction and make the clamping more secure. The side of the clamping block 222 that is close to the pressing table 12 will squeeze the expansion column 226. At this time, the spring 229 is in a compressed state.

[0041] At this point, the edge-pressing machine 1 is started to press the commemorative medal 13. When the punch 14 presses the commemorative medal 13 downward, it will be pressed into the interior of the edge-pressing seat 32. At the same time, the commemorative medal 13 will press the die 33 downward. When the bottom of the die 33 contacts the top of the fixed circular plate 34, the commemorative medal 13 can no longer move downward, and the edge pressing is completed. During unloading, the edge-pressing machine 1 is started to move the punch 14 upward. At this time, the top of the commemorative medal 13 loses downward pressure, and several springs 35 at the bottom of the edge-pressing seat 32 will push the die 33 and the die 34 downward through their own elastic force. When the commemorative medal 13 is reset, the electric push rod 211 is activated to extend, and its top pushes the lifting block 212 to move upward. At this time, the side of the three clamping columns 224 that is close to each other is no longer squeezed, and the three springs 229 push the three expansion columns 226 to expand each other through their own elasticity. The round end of the expansion column 226 will push the clamping block 222 to rotate clockwise around the pin. At the same time, when the lifting block 212 moves upward, it will push the commemorative medal 13 to move upward together through its top lifting column 31 to prevent the commemorative medal 13 from getting stuck in the pressure seat 32.
