Description

Technical Field

[0001] The invention relates to the technical field of tube seat processing and forming, in particular to a large laser tube seat processing and forming equipment. Background Art

[0002] The laser tube socket mainly plays the role of fixing and protecting electronic components. It is usually a shell structure and is made by stamping a plate using a forming device. During the stamping process, the existing forming device does not spray lubricating fluid on the surface of the plate, resulting in a rough surface of the stamped tube socket that cannot meet the use requirements. Long-term stamping causes the punch or upper die seat to heat up seriously, and the surface of the punch or upper die seat is deformed, so the punch or upper die seat cannot work for a long time. Therefore, the existing tube socket forming equipment has the following main problems: (1) There is no cooling treatment for the punch or upper die seat, resulting in a shortened service life of the punch or upper die seat; (2) Lubricating fluid is not sprayed on the stamping position, and stamping is performed directly, resulting in damage to the surface of the tube socket. Summary of the invention

[0006] The limiting plate is a circular plate, and two groups of opposite placement grooves are arranged on the lower side of the limiting plate. Both sides of the two groups of placement grooves are provided with insulating materials. The limiting plate outside the placement grooves is provided with a material with low thermal conductivity, and the material with low thermal conductivity prevents the heat generated when the positive plate and the negative plate are heated from being conducted upward. The positive plate and the negative plate are respectively installed in the placement grooves on both sides, and the positive plate and the negative plate are in contact with the material with low thermal conductivity. The positive plate and the negative plate are respectively electrically connected to the positive pole and the negative pole of the power supply;

[0007] A temperature difference plate A and a buffer plate are installed inside the limit plate, the temperature difference plate A is installed on the limit plate, the buffer plate is installed on the temperature difference plate A, the buffer plate is in contact with the upper mold base, the spray plate is hollow inside, a storage cylinder is provided on the upper side of the spray plate, a plurality of spray holes are provided on the lower side of the spray plate, and a temperature difference plate B is installed inside the spray plate,

[0008] The temperature difference plate A and the temperature difference plate B are provided with semiconductors and metal plates of two different materials, one end of the semiconductors of the two different materials are connected to the metal plate, the two semiconductors on the temperature difference plate A and the two semiconductors on the temperature difference plate B are connected by wires, one of which is connected to the control system; the two semiconductors and the metal plate on the temperature difference plate A are the hot ends of the Seebeck effect, and the two semiconductors and the metal plate on the temperature difference plate B are the cold ends of the Seebeck effect. The heat generated by the long-term stamping of the upper mold base is transferred to the buffer plate, and then transferred to the hot end through the buffer plate. The temperature difference plate B is located in the spray plate, and the temperature of the cold end is almost unchanged, so the temperature of the hot end is higher than the temperature of the cold end. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system detects the current and calculates it to obtain the temperature of the upper mold base around the temperature difference plate A. Then, the control system uses the current for cooling the refrigeration plate after rectification and voltage transformation. Compared with the traditional external fan cooling, the technical solution of cooling by using the internal energy generated by the upper mold base reduces energy consumption and improves the stability of the upper mold base.

[0009] A spiral groove is arranged inside the upper die base, and the spiral groove is distributed in a spiral line inside the upper die base. A plurality of cooling plates are installed in the upper die base near the spiral groove, and two semiconductors and metal plates of different materials are arranged on the plurality of cooling plates. One end of the two semiconductors of different materials on the cooling plates are connected to the metal plates, and the two semiconductors on the cooling plates are electrically connected to the control system through wires;

[0010] The current generated by the hot end and the cold end is transmitted to the two semiconductors on the cooling plate. The two semiconductors and the metal plate on the cooling plate are the cooling ends of the Peltier effect. The eardrum, the bimetallic plate and the coolant in the spiral groove are cooled through the cooling end. After the temperature of the two metal plates with different expansion coefficients on the bimetallic plate is reduced, due to the different degree of contraction, one of the metal plates drives the other metal plate to bend, so that the bimetallic plate bends to one side as a whole. The bimetallic plate bends and stretches the eardrum at the same time, making the wrinkles on the eardrum flat, increasing the cooling area of ​​the eardrum and improving the cooling effect.

[0011] The inlet of the spiral groove is connected to the vacuum pump through a pipeline, the vacuum pump is connected to the cooling box through a pipeline, the cooling box is connected to the outlet of the spiral groove through a pipeline, and the cooling box stores coolant; when the control system calculates the temperature of the upper mold base through the current generated by the hot end and the cold end, if the temperature is higher than the set value of the staff, the control system controls the vacuum pump to work, the vacuum pump draws the coolant in the cooling box into the spiral groove, the refrigeration plate increases the refrigeration area through the tympanic membrane, the tympanic membrane cools the coolant, and the cooled coolant flows in the spiral groove to cool the upper mold base, and then the coolant is discharged from the spiral groove into the cooling box to form a circulating flow of the coolant. Since the spiral groove is distributed in a spiral line, compared with the direct external cooling method, the interior of the upper mold base is cooled by the spiral groove and the coolant, which increases the cooling area of ​​the upper mold base, has a better cooling effect, and a faster cooling speed.

[0012] A bimetal plate is installed on one side of the plurality of groups of refrigeration plates, the bimetal plate is composed of two metal plates with different expansion coefficients, the two metal plates with different expansion coefficients are welded to each other, a plurality of tympanic membranes are connected between one end of the bimetal plate and the inner wall of the spiral groove, the other end of the bimetal plate is installed on the inner wall of the spiral groove, the refrigeration plate is wrapped by the plurality of tympanic membranes, and the plurality of tympanic membranes are provided with a plurality of folds;

[0013] When the cooling plate is cooling, the bimetal plate bends and stretches the eardrum at the same time, flattening the wrinkles on the eardrum, increasing the cooling area of ​​the eardrum and improving the cooling effect;

[0014] When the cooling plate is not cooling, the bimetal plate does not bend and the eardrum is in a wrinkled state.

[0015] The hydraulic cylinder is vertically mounted on the housing, the lifting cover is mounted on the piston rod of the hydraulic cylinder, the upper die seat is mounted on the lower side of the lifting cover, the positioning column is slidably connected to the inner wall of the upper die seat and the lifting cover, a second spring is connected between the positioning column and the lifting cover, a first spring is connected between the limit plate and the lifting cover, and the first spring buffers the limit plate to prevent the limit plate from directly hitting the surface of the plate, causing damage to the surface of the plate;

[0016] When not punching: the bottom of the positioning column, the bottom of the upper die seat and the bottom of the limit plate are in a flush state;

[0017] During stamping: the limit plate contacts the sheet, the upper die seat moves downward, and the positioning column stops moving after contacting the sheet.

[0018] The movable plate is provided with a plurality of through slots, the size of which is larger than the limiting plate, the spray plate is slidably connected to the through slots, the through slots limit and support the spray plate, a third spring is connected between the spray plate and the movable plate, the third spring is electrically connected to the control system through a wire, the spray plate is connected to the spray system through a pipeline, and the spray system is installed on the outer shell; the control system energizes the third spring, and after the third spring is energized, a magnetic field of mutual attraction is generated between each turn, and the magnetic field compresses the third spring. While the third spring pulls the spray plate and the storage tube to move from one side of the through slot to the other side, the spray system pressurizes the lubricating liquid and transports it to the spray plate, and the lubricating liquid is sprayed to the position on the surface of the plate that needs to be stamped through the spray hole and the one-way valve.

[0019] The movable plate is slidably connected to the housing, the movable plate is limited and supported by the housing, one side of the movable plate is connected to the output shaft of the electric cylinder, the electric cylinder is provided with multiple groups, and the multiple groups of the electric cylinders are all mounted on the housing;

[0020] The interior of the positioning column is hollow, and the middle part of the positioning column passes through the lifting cover through a pipeline and is connected to the negative pressure pump. The negative pressure pump is installed on the outer shell. The middle part of the positioning column cooperates with the negative pressure pump through the pipeline to generate negative pressure in the middle part of the positioning column, thereby realizing the adsorption of the positioning column to the pipe seat.

[0021] The sheet is conveyed to the lower die seat by the feeding mechanism, and the lower side of the sheet contacts the reciprocating plate in the lower die seat. The start button on the control panel is pressed, and the control system controls the third spring to be energized. Each turn of the third spring is gradually contracted by the mutually attractive magnetic field, and the third spring pulls the spray plate to move from one side of the through slot to the other side, and the storage cylinder on the spray plate follows the movement. During the movement of the spray plate, the spray system conveys the pressurized lubricating liquid to the spray plate, increasing the pressure inside the spray plate, and the lubricating liquid is sprayed on the position to be stamped through the one-way valve and the spray hole, thereby reducing the heat generated during stamping and reducing the burrs generated by stamping.

[0022] When the spray plate moves to the other side, the staff controls the hydraulic cylinder through the control system (the position of the hydraulic cylinder at this time is the initial position) to drive the lifting cover to move downward, and the lifting cover passes through the gap between the two adjacent storage cylinders to drive the upper die seat, the limit plate and the positioning column to move downward, so that the bottom of the limit plate, the bottom of the upper die seat and the bottom of the positioning column are in contact with the plate (the positive plate and the negative plate on the lower side of the limit plate are in contact with the plate), and the encoder inside the hydraulic cylinder feeds back data to the control system. The control system connects the positive plate and the negative plate to the positive and negative poles of the power supply respectively, so that the current flows through the plate between the positive plate and the negative plate, that is, flows through the position to be stamped, so that the pressure required for the hydraulic cylinder to drive the upper die seat to stamp downward is reduced, and the stress generated during stamping is reduced.

[0023] After the positive plate and the negative plate are heated to the stamping position for the set time, the control system cuts off the power to the positive plate and the negative plate. The set time is set in advance by the staff through the control system.

[0024] When the positive plate and the negative plate heat the position of the plate to be stamped, the control system controls the hydraulic cylinder to continue to drive the lifting cover to move downward, and the lifting cover drives the upper die seat to move downward, while the positioning column no longer moves due to the resistance of the plate. The positioning column compresses the second spring while positioning the middle of the plate to be stamped. The upper die seat stamps the plate into a disc shape downward and pushes the reciprocating plate to move downward. The reciprocating plate compresses the lower spring while moving downward. Since the middle part of the disc-shaped plate is positioned by the positioning column, the outer side of the disc-shaped plate is pushed downward by the upper die seat to bend into a round shell shape, and wrapped on the inner sleeve of the lower die seat. The upper die seat stamps the plate into a round shell-shaped tube seat to realize the stamping forming of the tube seat.

[0025] A one-way valve is installed in the spray hole, guide shafts are installed on both sides of the lifting cover, the guide shafts are slidably connected to the shell, the hydraulic cylinder is an electric hydraulic cylinder, and both the electric cylinder and the hydraulic cylinder are equipped with encoders and pressure sensors.

[0026] The lower die base is installed on the outer shell, and the lower die base consists of an inner sleeve and an outer sleeve. The inner sleeve is installed inside the outer sleeve, and the inner sleeve and the outer sleeve are both installed on the outer shell. The reciprocating plate is slidably installed between the inner sleeve and the outer sleeve, and a spring is connected between the lower side of the reciprocating plate and the outer shell.

[0027] A control panel is installed on the shell, and a control system is arranged inside the control panel.

[0028] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0029] 1. Use the internal energy generated by the stamping of the upper die seat for cooling and reducing energy consumption. The heat generated by the long-term stamping of the warm upper die seat is transferred to the buffer plate, and then to the hot end through the buffer plate. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system detects the current and calculates the temperature of the upper die seat around the temperature difference plate A. The control system then uses the current for cooling the refrigeration plate after rectification and voltage conversion. Compared with the traditional external fan cooling, the technical solution of cooling by the internal energy generated by the upper die seat reduces energy consumption and improves the stability of the upper die seat.

[0030] 2. Improve the cooling effect through the cooperation of the bimetallic plate and the eardrum. The current generated by the hot end and the cold end is transmitted to the two semiconductors on the cooling plate. The two semiconductors and the metal plate on the cooling plate are the cooling ends of the Peltier effect. The eardrum, the bimetallic plate and the coolant in the spiral groove are cooled by the cooling end. After the temperature of the two metal plates with different expansion coefficients on the bimetallic plate is reduced, due to the different degrees of contraction, one of the metal plates drives the other metal plate to bend, so that the bimetallic plate bends to one side as a whole. The bimetallic plate bends and stretches the eardrum at the same time, so that the wrinkles on the eardrum become flat, increasing the cooling area of ​​the eardrum and improving the cooling effect.

[0031] 3. Spray lubricating liquid on the stamping position to reduce the wear on the surface of the pipe seat. The third spring pulls the spray plate to move from one side of the through slot to the other side, and the storage tube on the spray plate moves accordingly. During the movement of the spray plate, the spray system delivers pressurized lubricating liquid to the spray plate, increasing the pressure inside the spray plate. The lubricating liquid is sprayed on the position to be stamped through the one-way valve and the spray hole, reducing the heat generated during stamping and reducing the burrs generated by stamping.

[0048] The limiting plate 22 is a circular plate, and two groups of opposite placement grooves are arranged on the lower side of the limiting plate 22. Both sides of the two groups of placement grooves are provided with insulating materials. The limiting plate 22 outside the placement groove is provided with a material with a low thermal conductivity coefficient. The material with a low thermal conductivity coefficient prevents the heat generated by the positive plate 221 and the negative plate 222 from being conducted upward when heated.

The heat generated by the long-term stamping of the upper mold base 24 is transferred to the buffer plate, and then transferred to the hot end through the buffer plate. The temperature difference plate B311 is located in the spray plate 31, and the cold end temperature is almost unchanged, so the hot end temperature is higher than the cold end temperature. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system.

When the control system detects that the current generated by the Seebeck effect is small, the control system directly supplies power to the cooling end.

[0049] The upper die base 24 is provided with a spiral groove 223 inside, and the spiral groove 223 is distributed in a spiral line inside the upper die base 24. A plurality of cooling plates 224 are installed in the upper die base 24 near the spiral groove 223. The plurality of cooling plates 224 are provided with semiconductors and metal plates of two different materials. One end of the semiconductors of two different materials on the cooling plate 224 is connected to the metal plate, and the two semiconductors on the cooling plate 224 are electrically connected to the control system through a wire; the current generated by the hot end and the cold end is transmitted to the two semiconductors on the cooling plate 224, The two semiconductors and metal plates on the cooling plate 224 are the cooling ends of the Peltier effect, through which the eardrum 27, the bimetallic plate 26 and the coolant in the spiral groove 223 are cooled. After the temperatures of the two metal plates with different expansion coefficients on the bimetallic plate 26 are reduced, due to the different degrees of contraction, one of the metal plates drives the other metal plate to bend, so that the bimetallic plate 26 is bent to one side as a whole. While the bimetallic plate 26 is bent, the eardrum 27 is stretched, so that the wrinkles on the eardrum 27 become flat, thereby increasing the cooling area of ​​the eardrum 27 and improving the cooling effect.

[0052] The working principle of the present invention is as follows: the sheet 12 is conveyed to the lower die base 23 by the feeding mechanism, the lower side of the sheet 12 contacts the reciprocating plate 231 in the lower die base 23, the start button on the control panel 1 is pressed, the control system controls the third spring 312 to be energized, each turn of the third spring 312 is gradually contracted by the mutually attractive magnetic field, the third spring 312 pulls the spray plate 31 to move from one side of the through groove to the other side, the storage tube on the spray plate 31 follows the movement, and during the movement of the spray plate 31, the spray system (not shown in the figure) conveys the pressurized lubricating liquid into the spray plate 31, so that the pressure inside the spray plate 31 increases, and the lubricating liquid is sprayed on the position to be stamped through the one-way valve and the spray hole, thereby reducing the heat generated during stamping, reducing the burrs generated by stamping, etc. The feeding mechanism and the spray system are prior art.

[0053] When the spray plate 31 moves to the other side, the staff controls the hydraulic cylinder 2 (the position of the hydraulic cylinder 2 at this time is the initial position) through the control system to drive the lifting cover 21 to move downward, and the lifting cover 21 passes through the gap between the two adjacent storage tubes to drive the upper die seat 24, the limit plate 22 and the positioning column 25 to move downward, so that the bottom of the limit plate 22, the bottom of the upper die seat 24 and the bottom of the positioning column 25 are in contact with the plate 12 (the positive plate 221 and the negative plate 222 on the lower side of the limit plate 22 are in contact with the plate 12), and the encoder inside the hydraulic cylinder 2 feeds back data to the control system, and the control system connects the positive plate 221 and the negative plate 222 to the positive and negative poles of the power supply respectively, so that the current flows from the plate 12 between the positive plate 221 and the negative plate 222, that is, flows through the position to be stamped, and the position to be stamped is heated, so that the pressure required for the hydraulic cylinder 2 to drive the upper die seat 24 to stamp downward is reduced, and the stress generated during stamping is reduced.

[0054] After the positive plate 221 and the negative plate 222 are heated to the position to be stamped for a set time, the control system cuts off the power to the positive plate 221 and the negative plate 222 . The set time is set in advance by the staff through the control system.

[0055] When the positive plate 221 and the negative plate 222 heat the plate 12 to be stamped at the position to be stamped for a set time, the control system controls the hydraulic cylinder 2 to continue to drive the lifting cover 21 to move downward, and the lifting cover 21 drives the upper die seat 24 to move downward, while the positioning column 25 is no longer moved due to the resistance of the plate 12, and the positioning column 25 compresses the second spring 251 while positioning the middle of the plate 12 to be stamped. The upper die seat 24 stamps the plate 12 downward into a disc shape and pushes the reciprocating plate 231 to move downward. The reciprocating plate 231 moves downward while compressing the spring on the lower side. Since the middle part of the disc-shaped plate 12 is positioned by the positioning column 25, the outer side of the disc-shaped plate 12 is pushed downward by the upper die seat 24 to bend into a round shell shape, and is wrapped on the inner sleeve of the lower die seat 23. The inner sleeve limits the size of the tube seat 16, and the upper die seat 24 stamps the plate 12 into a round shell-shaped tube seat 16 to achieve stamping forming of the tube seat 16.

[0056] After the tube seat 16 is stamped, the control system controls the negative pressure pump to work, and the air inside the positioning column 25 is extracted into the atmosphere through the negative pressure pump and the pipeline, so that negative pressure is generated inside the positioning column 25 to adsorb the middle part of the tube seat 16. After that, the control system controls the hydraulic cylinder 2 to drive the lifting cover 21 to move upward, and the lifting cover 21 drives the upper die seat 24, the limit plate 22 and the positioning column 25 to move upward, and the positioning column 25 drives the adsorbed tube seat 16 to move upward, so that the tube seat 16 is located above the spray plate 31. The encoder in the hydraulic cylinder 2 feeds back data to the control system. At this time, the control system will control the third spring The spring 312 is powered off, and the third spring 312 gradually becomes longer under the action of its own elastic force. The third spring 312 pushes the spray plate 31 and the storage barrel to move in the opposite direction to one side, so that the storage barrel is opposite to the tube seat 16. After that, the hydraulic cylinder 2 drives the tube seat 16 to move downward and place it on the storage barrel. The control system turns off the negative pressure pump to make the interior of the positioning column 25 at normal pressure. The positioning column 25 cannot adsorb the tube seat 16, and the tube seat 16 falls on the storage barrel. Finally, the control system drives the lifting cover 21, the limit plate 22 and the positioning column 25 to move upward to the initial position through the encoder data in the hydraulic cylinder 2.

[0057] After the hydraulic cylinder 2 returns to the initial position, the encoder inside the hydraulic cylinder 2 feeds back data to the control system. The control system controls the electric cylinder 13 to push the movable plate 3 to move outward. While the movable plate 3 slides on the outer shell 11, it drives the spray plate 31, the third spring 312, the storage tube and the pipe seat 16 to move outward. The staff removes the pipe seat 16 after stamping. After that, the staff drives the movable plate 3 back to the lower side of the lifting cover 21 through the control system and the electric cylinder 13, so that the upper die seat 24 can stamp the plate 12 next time.
