Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet stamping, and specifically relates to a metal sheet stamping device for socket processing. Background Art

[0002] A server is a specific IT device that provides computing power and runs software applications in a network environment. It provides computing or application services for other client computers in the network. Generally, a server has the ability to undertake response service requests, undertake services, and guarantee services. Compared with ordinary computers, a server has a high-speed CPU computing ability; the ability to run reliably for a long time; a powerful I / O data throughput ability and high scalability. As an electronic device, the internal structure of a server is very complex, and the server circuits are connected through a large number of sockets.

[0003] A socket refers to a seat into which one or more circuit wiring can be inserted. Through it, various wirings can be inserted to facilitate connection to other circuits. It is an electrical device that provides a power interface for household appliances and is also an electrical accessory used more frequently in residential electrical design. Through it, various wirings can be inserted, so that it is convenient to connect to other circuits. By connecting and disconnecting between the circuit and the copper part, the connection and disconnection of this part of the circuit can be achieved finally. The metal sheet in the socket is usually made of copper or copper alloy. These materials have good electrical conductivity, which can ensure that the current passes smoothly, thereby providing a stable power supply for the connected electrical appliances. As a part of the circuit, the metal sheet is responsible for transmitting electrical energy from the power supply to the electrical equipment, enabling the electrical appliances to work normally. The metal sheet helps to stably fix the plug in the socket, preventing the plug from loosening or falling off. This fixing effect is crucial for ensuring the stable power supply and safe use of electrical equipment. The metal sheet in the socket plays an important role in aspects such as electrical conduction, fixing and supporting, heat dissipation, protection, and grounding protection, and is a key component to ensure the safe and stable operation of electrical equipment.

[0004] For example, a metal sheet stamping device disclosed in the authorized announcement number CN221515863U has a structure including a device base. A fixed table is provided at the upper end of the device base. Fixed blocks are provided at both ends of the inner wall of the fixed table. Support frames are provided at both ends of the upper end of the fixed table. A support cross bar is provided at the upper end of the support frame. A stamping seat is provided below the support cross bar. Activity grooves are provided on both sides of the stamping seat inside the support frame. Buffer blocks are provided inside the activity grooves below the stamping seat. Top blocks are provided on both sides of the bottom end of the stamping seat. However, there are still many deficiencies in this application. When performing stamping operations, when the tool reciprocates up and down once, it can only stamp the metal sheet once, and the stamping efficiency is relatively low.

[0005] At present, after the tool in the stamping equipment has been punching the metal sheet for a long time, the surface of the tool will be partially worn. When the stamping continues, on the one hand, it is easy to leave scratches on the metal sheet. On the other hand, the cut surface of the metal sheet is prone to unevenness, and the probability of defects on the cut surface of the metal sheet is increased, which reduces the processing quality of the metal sheet. At this time, the tool needs to be replaced as a whole, and the replacement cost is high.

An intermittent plate 22 is installed on the outside of the feed roller 14, and a plurality of arc grooves 24 are provided on the circumferential side of the intermittent plate 22. It should be noted that the plurality of arc grooves 24 are distributed on the intermittent plate 22 in an annular array, and the plurality of toggle grooves 23 are distributed on the intermittent plate 22 in an annular array. The intermittent plate 22 and the arc grooves 24 are staggered, and the spindle plate 20 as a whole is a spindle. The spindle plate 20 is arranged in an arc shape, and is composed of two symmetrical fan-shaped plates. The outer edge of the spindle plate 20 is arranged in an arc shape, and the fixed plate 25 is arranged in the gap of the spindle plate 20. The fixed plate 25 and the spindle plate 20 are arranged vertically as a whole. A plurality of arc grooves 24 match the spindle plate 20.

At the same time, the crankshaft 8 drives the driving wheel 21 to rotate, the driving wheel 21 drives the driven wheel 19 to rotate, the driven wheel 19 drives the spindle plate 20 and the fixed plate 25 to rotate, and the fixed plate 25 drives the toggle block 27 to rotate through the telescopic plate 26. When the spindle plate 20 is in the arc groove 24, the intermittent plate 22 is in a stationary state. At this time, the cutter 3 continues to move upward to punch the metal sheet once. When the spindle plate 20 is about to leave the arc groove 24, the toggle block 27 will be stuck in the toggle groove 23. At this time, the lifting seat 2 has completed one stamping of the metal sheet. Under the rotation effect of the toggle block 27, the intermittent plate 22 is driven to rotate. The intermittent plate 22 drives the two feeding rollers 14 to rotate relatively. The feeding rollers 14 drive the conveyor belt 15 to rotate. The conveyor belt 15 pushes the metal sheet to move until it reaches a suitable position. At this time, the toggle block 27 is about to separate from the toggle groove 23, and the spindle plate 20 is about to enter the arc groove 24. The metal sheet stops being conveyed, and the lifting seat 2 continues to move up and down to stamp the metal sheet. When the lifting seat 2 moves up and down once, the metal sheet can be stamped twice, thereby improving the stamping efficiency of the metal sheet.

[0041] In the present invention, the tool changing mechanism 5 includes an adjusting chamber 32 arranged in the lifting seat 2, and two bidirectional screws 37 are rotatably connected in the adjusting chamber 32, and the bidirectional screws 37 are externally threadedly connected to the lifting plate 33. It should be noted that the friction between the bidirectional screws 37 and the lifting plate 33 is relatively large. According to the self-locking performance of the threaded rod, the lifting plate 33 cannot drive the bidirectional screws 37 to rotate in the reverse direction, and has a self-locking performance. The lifting plate 33 is slidably connected to the adjusting chamber 32, and a rotating rod 36 is arranged in the adjusting chamber 32. One end of the rotating rod 36 rotates through the lifting seat 2 and is installed Rotate the nut 38, the rotating rod 36 and the bidirectional screw 37 are connected through a bevel gear set 39. It is worth mentioning that the bevel gear set 39 includes a first bevel gear 40 and two second bevel gears 41. The two second bevel gears 41 are meshed and connected with the first bevel gear 40. The first bevel gear 40 is installed with the rotating rod 36, and the two second bevel gears 41 are installed with the two bidirectional screws 37 respectively. A fixing rod 34 is installed on the opposite side of the two lifting plates 33, and the end of the fixing rod 34 away from the lifting plate 33 is connected to the block 30 through a connecting column 31.

It should be noted that the clamping mechanism 35 includes two L-shaped clamping plates 49 slidably connected with the cavity 48, the L-shaped clamping plates 49 match the block 30, and the cavity 48 is rotatably connected with a screw rod 42, the screw rod 42 is threaded through the two L-shaped clamping plates 49, and the outer sleeve of the screw rod 42 is provided with a reset spring 43, and the two ends of the reset spring 43 are respectively fixedly connected to the two L-shaped clamping plates 49. It should be noted that The friction between the screw rod 42 and the L-shaped card plate 49 is small, and the screw rod 42 has no limiting effect on the L-shaped card plate 49. The L-shaped card plate 49 will always remain at the positions on both sides of the cavity 48 under the elastic force of the reset spring 43. One end of the screw rod 42 rotates to penetrate the cutter 3 and is installed with an adjusting nut 44. It is worth mentioning that the side wall of the block 30 is provided with a limiting groove, and the limiting groove faces the direction away from the inner wall of the adjacent groove 29 to facilitate the connection between the block 30 and the L-shaped card plate 49. A smooth inclined surface is provided on the side of the L-shaped card plate 49 close to the protrusion 28, and the inclined surface faces the direction away from the other L-shaped card plate 49. The side of the L-shaped card plate 49 with the inclined surface matches the limiting groove.

[0043] Through the above technical features: when the tool needs to be replaced after long-term use, turn the rotating nut 38 with an Allen wrench. The rotating nut 38 drives the rotating rod 36 to rotate. The rotating rod 36 drives the two lifting plates 33 to rotate. The lifting plates 33 drive multiple clamping blocks 30 to move through the fixing rods 34 and the connecting columns 31. The clamping blocks 30 drive the cutting tool 3 to move until it reaches the appropriate position. Then, turn the adjusting nut 44 with an Allen wrench. The adjusting nut 44 drives the lead screw 42 to rotate. The lead screw 42 drives the two L-shaped clamping plates 49 to move until the L-shaped clamping plates 49 move out of the limiting grooves on the clamping blocks 30. At this time, the cutting tool 3 can be removed and a new cutting tool 3 can be replaced. Then, reverse-rotate the rotating nut 38, and tightly fix the cutting tool 3 on the lifting seat 2 through the clamping blocks 30, and the replacement of the tool can be completed. There is no need to replace the whole tool, which reduces the tool replacement cost.

[0044] Working principle:

[0045] 1) Tool replacement: For tool replacement, turn the rotating nut 38 with an Allen wrench. The rotating nut 38 drives the rotating rod 36 to rotate. The rotating rod 36 drives the two lifting plates 33 to rotate. The lifting plates 33 drive multiple clamping blocks 30 to move through the fixing rods 34 and the connecting columns 31. The clamping blocks 30 drive the cutting tool 3 to move until it reaches the appropriate position. Then, turn the adjusting nut 44 with an Allen wrench. The adjusting nut 44 drives the lead screw 42 to rotate. The lead screw 42 drives the two L-shaped clamping plates 49 to move until the L-shaped clamping plates 49 move out of the limiting grooves on the clamping blocks 30. At this time, the cutting tool 3 can be removed and a new cutting tool 3 can be replaced. Then, reverse-rotate the rotating nut 38, and tightly fix the cutting tool 3 on the lifting seat 2 through the clamping blocks 30, and the replacement of the tool can be completed;

[0046] 2) Stamping the metal sheet: The crankshaft 8 is driven by the driving motor 9 to rotate, and the crankshaft 8 drives the lifting rod 10 to move upward. The lifting rod 10 drives the lifting seat 2 to move up and down through the sliding rod 12. At the same time, the crankshaft 8 drives the driving wheel 21 to rotate, and the driving wheel 21 drives the driven wheel 19 to rotate. The driven wheel 19 drives the spindle plate 20 and the fixed plate 25 to rotate. The fixed plate 25 drives the toggle block 27 to rotate through the telescopic plate 26. When the spindle plate 20 is in the arc groove 24, the intermittent plate 22 is in a stationary state. At this time, the cutter 3 continues to move upward to punch the metal sheet once. When the spindle plate 20 is about to leave the arc groove 2 4, the toggle block 27 will be stuck in the toggle groove 23. At this time, the lifting seat 2 has completed one stamping of the metal sheet. Under the rotation effect of the toggle block 27, the intermittent plate 22 is driven to rotate. The intermittent plate 22 drives the two feeding rollers 14 to rotate relatively. The feeding rollers 14 drive the conveyor belt 15 to rotate. The conveyor belt 15 pushes the metal sheet to move until it is in a suitable position. At this time, the toggle block 27 is about to separate from the toggle groove 23, and the spindle plate 20 is about to enter the arc groove 24. The metal sheet stops being conveyed, and the lifting seat 2 continues to move up and down to stamp the metal sheet. When the lifting seat 2 moves up and down once, the metal sheet can be stamped twice.
