Description

Technical Field

[0001] The invention relates to the technical field of stamping and forming devices, in particular to a stamping and forming device for a relay metal sheet. Background Art

[0002] A relay is an electrical control device, usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control a large current, and plays the role of automatic regulation, safety protection, and circuit conversion in the circuit. Relays are widely used in power systems, automated control, safety protection, circuit conversion, and other fields. Relays include electromagnetic relays, current relays, etc. Each type of relay has its specific application scenarios and technical requirements.

[0003] The metal sheet inside the relay is made by stamping. Stamping is a metal processing method in which a mold is used to apply pressure to the material to cause it to separate or plastically deform, thereby obtaining the desired parts. In the manufacturing process of relays, the stamping process is used to make metal sheets, which is a common metal stamping part. The existing relay stamping forming device has the following main problems: (1) The stamping plate is not cooled down in time during long-term operation, causing the stamping plate to heat up and deform; (2) The stamping plate is not cleaned, resulting in unqualified metal sheets after stamping. Summary of the invention

[0004] The object of the present invention is to provide a relay metal sheet stamping forming device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a relay sheet metal stamping forming device, comprising a cooling system, comprising a frame, a feed port is arranged at one end of the frame, a lifting electric cylinder is installed on the frame, a lifting cover is installed on the telescopic rod of the lifting electric cylinder, an upper partition and a cam are installed in sequence in the lifting cover, a brush plate is installed on the upper partition, a rotating cylinder is installed on the outer side of the cam, a stamping plate is slidably installed on the rotating cylinder, a first spring is connected between the rotating cylinder and the stamping plate, a lower partition is installed below the rotating cylinder, a conveying unit is installed on both sides of the lower partition, and a lower die seat is installed in the middle of the lower partition;

[0006] The conveying unit conveys the plate, the stamping plate and the lower die seat cooperate to stamp the plate into a metal sheet, the first spring and the brush plate cooperate to clean the stamping plate, and the rotating cylinder adjusts the position of the stamping plate.

[0007] The cam is located below the upper baffle, the upper baffle is mounted on the lifting cover, a plurality of protrusions are arranged on the circumference of the cam, both ends of the cam are mounted on the lifting cover, the interior of the cam is hollow, a connecting port is arranged at the position of the protrusion, the interior of the cam is connected to the cooling system through a pipeline, the cooling system is mounted on the frame, the cooling system cools and pressurizes the lubricating fluid and then transports it to the interior of the cam, and the connecting port is connected to the interior of the cam;

[0008] The cam and the rotating cylinder are rotatably connected via a bearing, the rotating cylinder is provided with multiple sets of sliding grooves, the stamping plates are provided with multiple sets, one end of the multiple sets of stamping plates is provided with rollers, the rollers pass through the sliding grooves and abut against the cams, the other end of the stamping plates is adapted to the surface of the metal sheet, the first spring is sleeved on the stamping plate, and the first spring is electrically connected to the control system. When the rotating cylinder rotates, the rotating cylinder drives the stamping plate to rotate through the sliding grooves, and the rollers on the stamping plates slide on the cam while following the rotation.

[0009] Press the start button on the control panel to start the device. The staff puts the plate from the feed port to the position between the conveying wheels on both sides. The encoder in the conveying wheel feeds back the displacement data of the plate to the control system. The conveying wheels on both sides convey the position where the plate needs to be punched to the bottom of the rotating cylinder. The driving motor drives the gear to rotate, and the gear drives the rotating cylinder to rotate through the tooth structure. The rotating cylinder drives the stamping plate to rotate a certain angle, so that one group of stamping plates is located directly above the position where the plate needs to be stamped and is in a vertical state.

[0010] When the stamping plate rotates at a certain angle, the roller at one end of the stamping plate slides on the cam and contacts the protrusion. The protrusion on the cam pushes the stamping plate to move outward, and the stamping plate compresses the first spring at the same time. When the stamping plate is in a vertical state, the connecting port on the cam and the output port on the stamping plate are in a locked state. At this time, the encoder in the drive motor feeds data back to the control system. The control system controls the cooling system to pressurize and cool the lubricating fluid and then transport it to the cam. After passing through the inside of the cam, the lubricating fluid enters the inside of the stamping plate from the connecting port and the output port, and is cooled again by the refrigeration plate inside the stamping plate, so that the cooled lubricating fluid flows inside the stamping plate and is sprayed from the spray port A on the position where the plate needs to be stamped. While cooling the stamping plate, the position where the plate needs to be stamped is lubricated, thereby reducing the friction during the stamping process and reducing the surface wear of the metal plate during the stamping process.

[0011] When the lubricating liquid is sprayed on the position where the plate needs to be stamped, the cooling system feeds back the flow data of the lubricating liquid to the control system. The control system controls the lifting electric cylinder to drive the lifting cover to move downward, the lifting cover drives the cam and the rotating cylinder to move downward, the rotating cylinder drives the stamping plate to move downward, and the lowest stamping plate and the lower die seat cooperate to stamp the plate into a metal sheet. The metal sheet falls from the lower die seat and is collected and processed by the staff.

[0012] After the plate is punched into a metal sheet, the lifting electric cylinder feeds back the displacement data to the control system. The control system controls the lifting electric cylinder to drive the lifting cover to move upward, the lifting cover drives the cam and the rotating cylinder to move upward, and the rotating cylinder drives the stamping plate to move upward and be located above the plate.

[0013] When the stamping plate on the lower side of the rotating cylinder is above the plate, the lifting electric cylinder feeds back data to the control system. The control system drives the gear to rotate through the driving motor, and the gear drives the rotating cylinder to rotate. The rotating cylinder drives the stamping plate on the lower side to rotate a certain angle, so that the lowest stamping plate rotates to the upper side of the rotating cylinder, so that the rotated stamping plate is directly below the brush plate.

[0014] When the rotating stamping plate is directly below the brush plate, the encoder in the drive motor feeds data back to the control system, and the control system passes a positive current through the first spring to generate a positive magnetic field. The positive magnetic field generated by the first spring attracts the magnetic material on the brush plate. Under the attraction, the brush plate moves downward and stretches the spring. During the downward movement of the brush plate, the brush in the brush plate cleans the surface of the stamping plate. After that, the control system cuts off the power of the first spring. When the magnetic field of the first spring disappears, the brush plate is pulled upward by the spring, and the brush in the brush plate cleans the stamping plate again. The control system continuously powers on and off the first spring to achieve reciprocating cleaning of the stamping plate by the brush plate. The staff adjusts the frequency of powering on and off the first spring to adjust the frequency of brush cleaning the stamping plate to meet different usage scenarios.

[0015] After the stamping plate is cleaned by the brush plate, the control system cuts off the power to the first spring, and the brush plate is pulled to the top of the stamping plate by the spring. The control system controls the cooling system to pressurize and cool the lubricating fluid and then transport it to the spray port B through the pipeline. The lubricating fluid is sprayed on the surface of the stamping plate through the spray port B, so that the subsequent stamping plate can continue to stamp the plate, thereby extending the service life of the stamping plate.

The lower side of the stamping plate is provided with a spray port A, and a refrigeration plate is installed inside the stamping plate, and the spray port A is connected to the interior of the stamping plate. When the driving motor drives the rotating cylinder to rotate through the gear, and the rotating cylinder drives one group of stamping plates to be in a vertical state, the protrusion on the cam pushes the stamping plate outward to the farthest position, and the stamping plate stretches the first spring. At this time, the output port on the stamping plate and the connecting port on the cam are mutually engaged and in a connected state.

[0017] The conveying unit is composed of multiple groups of conveying wheels, which are installed on both sides of the lower partition in sequence, and are directly opposite to the feed port.

[0022] The refrigeration plate is provided with semiconductors and metal plates of two different materials, one end of the semiconductors of two different materials is connected to the metal plate, and the semiconductors of two different materials are electrically connected to the control system through a wire. The semiconductors of two different materials and the metal plate on the refrigeration plate are the refrigeration ends of the Peltier effect, and the control system cools the lubricating liquid again through the refrigeration end, so that the lubricating liquid cools the stamping plate and the position where the plate needs to be stamped at the same time, thereby improving the cooling effect and reducing the wear of the stamping plate.

[0040] The cam 21 is located below the upper partition 111, and the upper partition 111 is installed on the lifting cover 121. A number of protrusions are arranged on the circumference of the cam 21. Both ends of the cam 21 are installed on the lifting cover 121. The interior of the cam 21 is hollow. The cam 21 is provided with a connecting port 211 at the position of the protrusion. The interior of the cam 21 is connected with the cooling system through a pipeline. The cooling system is installed on the frame 11. The cooling system cools and pressurizes the lubricating fluid and then transports it to the interior of the cam 21. The connecting port 211 is connected with the interior of the cam 21; the cam 21 and the rotating cylinder 22 are rotatably connected through a bearing, and the rotating cylinder 22 is provided with multiple groups of sliding grooves, and the stamping plate 23 is provided with multiple groups.

[0041] The roller is provided with an output port 231, which is provided on a side close to the cam 21. The output port 231 and the connecting port 211 are connected in a snap-on manner. The upper side of the stamping plate 23 is hollow, and the interior of the stamping plate 23 is connected to the output port 231.

The control system cools down the lubricant again through the cooling end, so that the lubricant cools down the positions of the stamping plate 23 and the plate 13 that need to be stamped at the same time, thereby improving the cooling effect and reducing the wear of the stamping plate 23. When the driving motor 2 drives the rotating cylinder 22 to rotate through the gear 15, the rotating cylinder 22 drives one group of stamping plates 23 to be in a vertical state, the protrusion on the cam 21 pushes the stamping plate 23 outward to the farthest position, and the stamping plate 23 stretches the first spring 241. At this time, the output port 231 on the stamping plate 23 and the connecting port 211 on the cam 21 are engaged with each other and are in a connected state.

[0042] The conveying unit is composed of multiple groups of conveying wheels 14, which are installed on both sides of the lower partition 112 in sequence, and the multiple groups of conveying wheels 14 are opposite to the feed port 113. The conveying wheel 14 has an electric roller structure inside, and an encoder and a pressure sensor are built in the conveying wheel 14. The lower partition 112 is installed on the frame 11, and multiple groups of through grooves are arranged on the lower partition 112 between the conveying wheels 14 on both sides, and the multiple groups of through grooves are opposite to the stamping plate 23.

[0043] The interior of the brush plate 24 is adapted to the surface of the stamping plate 23, the brush plate 24 is opposite to the first spring 241, a magnetic material is provided at the lower end of the brush plate 24, the brush plate 24 is slidably mounted on the upper partition 111 through a guide shaft 242, the guide shaft 242 is mounted on the upper partition 111, and the brush plate 24 and the upper partition 111 are connected by a spring; the interior of the brush plate 24 is hollow, a brush is provided inside the brush plate 24, a spray port B243 is provided at the bottom of the brush plate 24, and the spray port B243 is connected to the cooling system through a pipeline.

[0044] Working principle: Press the start button on the control panel 1 to start the device. The staff puts the plate 13 from the feed port 113 to the position between the conveying wheels 14 on both sides. The encoder in the conveying wheel 14 feeds back the displacement data of the plate 13 to the control system. The conveying wheels 14 on both sides convey the position where punching holes are required on the plate 13 to the bottom of the rotating cylinder 22. The driving motor 2 drives the gear 15 to rotate. The gear 15 drives the rotating cylinder 22 to rotate through the tooth structure. The rotating cylinder 22 drives the stamping plate 23 to rotate a certain angle, so that one group of stamping plates 23 is located directly above the position where the plate 13 needs to be stamped and is in a vertical state.

[0045] When the stamping plate 23 rotates a certain angle, the roller at one end of the stamping plate 23 slides on the cam 21 and contacts the protrusion. The protrusion on the cam 21 pushes the stamping plate 23 to move outward, and the stamping plate 23 compresses the first spring 241 at the same time. When the stamping plate 23 is in a vertical state, the connecting port 211 on the roller and the output port 231 on the stamping plate 23 are in a snap-fit ​​state. At this time, the encoder in the drive motor 2 feeds back data to the control system, and the control system controls the cooling system to pressurize and cool the lubricating fluid and then output it. The lubricating liquid is delivered to the cam 21, and then passes through the inside of the cam 21 and enters the inside of the stamping plate 23 from the connecting port 211 and the output port 231. The lubricating liquid is cooled again by the refrigeration plate 232 inside the stamping plate 23, so that the cooled lubricating liquid flows inside the stamping plate 23 and is sprayed from the spray port A233 on the position of the sheet 13 that needs to be stamped. While cooling the stamping plate 23, the position of the sheet 13 that needs to be stamped is lubricated, thereby reducing the friction during the stamping process and reducing the surface wear of the metal plate during the stamping process.

[0046] When the lubricating liquid is sprayed on the position of the plate 13 that needs to be stamped, the cooling system feeds back the flow data of the lubricating liquid to the control system, and the control system controls the lifting electric cylinder 12 to drive the lifting cover 121 to move downward, the lifting cover 121 drives the cam 21 and the rotating cylinder 22 to move downward, and the rotating cylinder 22 drives the stamping plate 23 to move downward, and the lowest stamping plate 23 and the lower die base 25 cooperate to stamp the plate 13 into a metal sheet, and the metal sheet falls from the lower die base 25 and is collected and processed by the staff.

[0047] When the plate 13 is punched into a metal sheet, the lifting cylinder 12 feeds back the displacement data to the control system. The control system controls the lifting cylinder 12 to drive the lifting cover 121 to move upward. The lifting cover 121 drives the cam 21 and the rotating cylinder 22 to move upward. The rotating cylinder 22 drives the stamping plate 23 to move upward and is located above the plate 13.

[0048] When the stamping plate 23 on the lower side of the rotating cylinder 22 is located above the plate 13, the lifting electric cylinder 12 feeds back data to the control system, and the control system drives the gear 15 to rotate through the driving motor 2, and the gear 15 drives the rotating cylinder 22 to rotate, and the rotating cylinder 22 drives the stamping plate 23 on the lower side to rotate a certain angle, so that the lowest stamping plate 23 rotates to the upper side of the rotating cylinder 22, so that the rotated stamping plate 23 is located directly below the brush plate 24.

[0049] When the rotating stamping plate 23 is located directly below the brush plate 24, the encoder in the driving motor 2 feeds data back to the control system, and the control system passes a positive current into the first spring 241, so that the first spring 241 generates a positive magnetic field. The positive magnetic field generated by the first spring 241 attracts the magnetic material on the brush plate 24. Under the action of the attraction, the brush plate 24 moves downward and stretches the spring. During the downward movement of the brush plate 24, the brush cleans the surface of the stamping plate 23. After that, the control system cuts off the power of the first spring 241. When the magnetic field of the first spring 241 disappears, the brush plate 24 is pulled upward by the spring, and the brush in the brush plate 24 cleans the stamping plate 23 again. The control system continuously energizes and deenergizes the first spring 241, so that the brush plate 24 can reciprocate up and down cleaning of the stamping plate 23. The staff adjusts the frequency of the brush cleaning the stamping plate 23 by adjusting the frequency of the first spring 241 energizing and deenergizing to meet different usage occasions.

[0050] After the stamping plate 23 is cleaned by the brush plate 24, the control system cuts off the power to the first spring 241, and the brush plate 24 is pulled to the top of the stamping plate 23 by the spring. The control system controls the cooling system to pressurize and cool the lubricating fluid and then transport it to the spray port B243 through a pipeline, and then sprays it on the surface of the stamping plate 23 through the spray port B243, so that the subsequent stamping plate 23 can continue to stamp the sheet 13, thereby extending the service life of the stamping plate 23.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
