Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a stamping repair mold with automatic part removal. Background Technology

[0002] Molds are used to shape objects by altering the physical state of the material being molded. Because of their high forming speed, molds are widely used in the mass production of various industrial products. In the production of automotive parts, molds are used to stamp sheet metal parts, including trimming and punching, to remove excess material from the edges of the sheet metal parts or to machine the necessary holes.

[0003] Currently, after forming and finishing, most raw material sheets are manually removed from the die. However, the surface of the product has a certain temperature after processing, and manual removal can easily cause burns to workers. Furthermore, waste material from the die usually falls directly into the discharge channel through the waste outlet. Because there is a certain distance between the waste outlet and the discharge channel, the waste material collides with the discharge channel, causing debris to fly everywhere and injure workers. Moreover, without a waste material discharge auxiliary device, waste material may accumulate in the discharge channel. Therefore, it is necessary to design an automatic part-removing stamping die that facilitates automatic material removal and avoids waste splashing during the discharge process. Summary of the Invention

An auxiliary discharge mechanism is provided on the side of the lower die base near the waste discharge channel.

[0013] According to the automatic part removal stamping and repair die, the auxiliary material discharge mechanism includes a fixed plate installed on the lower die base. A connector one and a connector two are installed on the fixed plate.

Detailed Implementation

[0037] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0038] Reference Figures 1-13 An automatic part-removing stamping and repair die includes a lower die base 1; an upper die base 2 is movably connected above the lower die base 1; an upper pad 3 is installed on the upper die base 2; a punch 4 is installed on the upper pad 3; a lower pad 5 is installed on the lower die base 1; a die 6 is installed on the lower pad 5; a through hole 7 adapted to the punch 4 is opened on the die 6; a waste discharge port 8 is opened below the die 6; and a waste discharge channel 9 is provided on the lower die base 1 for discharging waste sheet metal stamped and repaired by the punch 4 and the die 6.

[0039] A material-grabbing mechanism 10 is installed on the lower mold base 1. The material-grabbing mechanism 10 includes a fixed base 101 symmetrically fixed on the lower mold base 1, a support rod 102 movably connected to the fixed base 101, a material-grabbing assembly 103 installed on the support rod 102 in a linear array, a support base 104 fixed on the lower mold base 1, a telescopic cylinder 105 installed on the support base 104, a U-shaped connector 106 installed at the output end of the telescopic cylinder 105, and a connecting plate 107 rotatably connected to one side of the U-shaped connector 106. The material-grabbing assembly 103 includes components symmetrically opened on the support rod 102. The outer wall has a positioning groove 1030, and support blocks 1031 and 1032 are placed on the inner wall of the positioning groove 1030. Support blocks 1031 and 1032 are detachable by screws. A rod 1033 is provided on support block 1031. There are three sets of material picking components 103 and two rods 1033. Two sets of material picking components 103 are symmetrically installed on support rods 102. The two support blocks 1031 of the two sets of material picking components 103 are fixedly connected to the two rods 1033. The support block 1031 of the other set of material picking components 103 is fixedly connected to the two rods 1033. A material-retrieving mechanism 10 is fixedly connected to the connecting plate 107. This mechanism facilitates the removal of the formed sheet material without manual handling. Given the extremely high temperature of the formed sheet material, the automatic material-retrieving method using the mechanism 10 is more convenient and prevents burns to workers, ensuring their safety. When the formed sheet material needs to be unloaded or retrieved, the telescopic cylinder 105 is activated. The telescopic cylinder 105 drives the U-shaped connector 106 to move, which in turn causes the connecting plate 107 to rotate on its inner wall. The rotation of the connecting plate 107 then causes the support block 1031 to rotate. Since support block 1031 and support block 2 1032 are installed on support rod 102, support block 1031, support block 2 1032 and support rod 102 rotate synchronously. The rotation of support block 1031 drives rod 1033 to rotate upward. Another support block 1031 connected to rod 1033 rotates synchronously under the drive of support rod 102. Thus, the two rods 1033 rotate upward synchronously, which unloads and picks up the formed plate, effectively saving material picking time, reducing the labor intensity of workers, and making it easy to use, thereby improving the convenience and practicality of the device.

[0040] A telescopic cylinder 19 is installed on the lower mold base 1. A fixing block 20 is installed at one end of the telescopic cylinder 19. A servo motor 21 is fixed to one side of the fixing block 20. A rotating shaft 22 is fixed to the output end of the servo motor 21. A rotating sleeve 23 is fixedly connected to the outer wall of the rotating shaft 22. A bearing frame 24 is fixed to one side of the rotating sleeve 23. A pressure sensor 25 is installed inside the bearing frame 24. A displacement sensor 26 is installed on one side of the lower surface of the bearing frame 24. The telescopic cylinder 19, servo motor 21, pressure sensor 25, and displacement sensor 26 are all connected to an external control system. The external control system can drive their start and stop. The bearing frame 24 can prevent waste from falling directly onto the waste discharge channel 9 and causing debris to splash. When waste falls onto the bearing frame 24 and affects the reading of the pressure sensor 25, when the pressure sensor 25... When the reading changes, the pressure sensor 25 transmits a signal to the control system. The control system then activates the telescopic cylinder 19. The activation of the telescopic cylinder 19 causes the support frame 24 to descend via the fixed block 20. During the descent of the support frame 24, the displacement sensor 26 continuously monitors the distance between its lower surface and the waste discharge channel 9. Once the support frame 24 has descended to a certain distance, the displacement sensor 26 transmits a signal to the control system. The control system then activates the servo motor 21, which drives the rotating shaft 22 to rotate. The rotating shaft 22 then drives the rotating sleeve 23 to rotate, which in turn drives the support frame 24 to rotate at the same angle as the waste discharge channel 9. This prevents waste from falling directly onto the waste discharge channel 9 and causing debris to splash. The buffered descent feeding method avoids debris splashing, thus ensuring the safety of the workers.

[0041] A guide post 11 and a spring assembly 12 are provided between the lower mold base 1 and the upper mold base 2 to ensure the stability of the upper mold base 2 during lifting.

[0042] The size of the waste discharge port 8 is larger than the size of the through hole 7, and the width of the waste discharge channel 9 is larger than the size of the waste discharge port 8. This can prevent waste from clogging the waste discharge port 8. The maximum drop height of the punch 4 is consistent with the height of the inner wall of the through hole 7. Therefore, the size of the waste discharge port 8 is set to be larger than the size of the through hole 7, so that the waste can fall smoothly onto the support frame 24, which is convenient to use.

[0043] The lower surface of the upper die base 2 is symmetrically equipped with wedge cutter blocks 13, and the lower backing plate 5 is equipped with a second die cavity 14 that cooperates with the wedge cutter blocks 13. The lower die base 1 is provided with an auxiliary material discharge mechanism 15 on the side near the waste discharge channel 9. The wedge cutter blocks 13 and the second die cavity 14 can punch and trim the raw material sheet.

[0044] The auxiliary material feeding mechanism 15 includes a fixed plate 1501 mounted on the lower mold base 1. A first connector 1502 and a second connector 1503 are mounted on the fixed plate 1501. An air supply pipe 1504 is mounted on one side of the first connector 1502, and a tee connector 1505 is mounted on the other end of the first air supply pipe 1504. Air supply pipes 1506 are mounted on the inner walls of the other interfaces of the tee connector 1505. A nozzle 1507 is mounted on one end of the second air supply pipe 1506, and an air supply pipe 1507 is mounted on one side of the second connector 1503. 08. A four-way connector 1509 is installed at the other end of the air supply pipe 1508. Air supply pipes 1510 are installed on the inner walls of the other interfaces of the four-way connector 1509. A nozzle 1511 is installed at one end of the air supply pipe 1510. The positions of nozzles 1507 and 1511 correspond to the positions of the waste discharge channel 9. A connector 16 is installed on the fixing plate 1501. An air supply pipe 17 is connected to the telescopic cylinder 105. The air supply pipe 17 is connected to the connector 16. The connector 16... Head 1502 and Connector 2 1503 are connected to an external air pump. A bracket 18 is installed on the side of the lower mold base 1 near nozzle 1507 and nozzle 2 1511. The bracket 18 supports nozzle 1507 and nozzle 2 1511. Connector 1502 and Connector 2 1503 of the auxiliary discharge mechanism 15 are respectively connected to an external air pump. The external air pump provides air to nozzle 1507 and nozzle 2 1511. The gas is supplied through air supply pipe 1 1504, air supply pipe 2 1506, air supply pipe 3 1508, and... The gas supply pipe 1510 delivers gas to nozzles 1507 and 1511. Nozzles 1507 and 1511 spray gas into the waste discharge channel 9, thereby blowing the waste on the support frame 24 onto the waste discharge channel 9 for discharge, thus achieving the purpose of assisting in material discharge and preventing waste debris from remaining on the waste discharge channel 9. The bracket 18 is used to support the stability of the gas supply pipes 1506 and 1510, and a limiting slot is used to prevent the gas supply pipes 1506 and 1510 from falling off.

[0045] Working Principle: When profile forming and trimming are required, the raw material sheet is placed on the die 6. The upper die base 2 is connected to an external press. The press drives the upper die base 2 to rise and fall. The guide column 11 and spring assembly 12 ensure the stability of the upper die base 2 during rising and falling. The upper die base 2 descends, causing the upper pad 3 and punch 4 to descend. The punch 4 aligns with the through hole 7 on the die 6 and moves down a certain distance into the through hole 7. During the downward movement, it works with the die 6 to form and trim the raw material sheet. The scrap is pushed out of the through hole 7 by the punch 4 and falls from the scrap outlet 8 onto the support frame 24. The pressure sensor 25 on the support frame 24 changes its value and transmits the signal to the external control system. The control system drives the telescopic cylinder 19 to start. The telescopic cylinder 19 drives the support frame 24 to descend through the fixing block 20. During the descent, the displacement sensor 26 detects the distance between the lower surface of the support frame 24 and the scrap discharge channel 9 in real time. When the descent height set by the displacement sensor 26 is reached, the pressure sensor 26 determines the descent height. The displacement sensor 26 transmits the signal to the external control system. The control system drives the servo motor 21 to start, the servo motor 21 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the rotating sleeve 23 to rotate, the rotating sleeve 23 drives the bearing frame 24 to rotate. After the bearing frame 24 rotates to the same angle as the waste discharge channel 9, the waste is discharged through the auxiliary discharge mechanism 15. During the process of the upper mold base 2 driving the punch 4 to descend, the upper mold base 2 drives the inclined wedge block 13 to descend synchronously. The inclined wedge block 13 corresponds to the second die 14 to achieve the purpose of trimming the edge of the raw material plate. Similarly, the waste will fall into the corresponding waste discharge channel 9. However, there is no bearing frame 24 below the waste. The reason for not setting it is that the distance between the waste discharge channel 9 and the second die 14 is not high. The corresponding waste discharge channel 9 is equipped with a smooth sound-silencing pad, so the falling sound will not be loud. And because the distance is not high, the waste will not produce debris splashing when it comes into contact with the waste discharge channel 9.

[0046] The auxiliary discharge mechanism 15 has two connectors, 1502 and 1503, which are connected to an external air pump. The external air pump provides air to nozzles 1507 and 1511. The gas is delivered to nozzles 1507 and 1511 through air pipes 1504, 1506, 1508, and 1510. Nozzles 1507 and 1511 spray the gas toward the waste discharge channel 9, so that the waste on the support frame 24 is blown off by the gas and discharged onto the waste discharge channel 9, thereby achieving the purpose of auxiliary discharge and avoiding the residue of waste debris on the waste discharge channel 9.

[0047] After the sheet metal is finished being punched, the upper die base 2 is raised by an external press, causing the punch 4 to disengage from the die 6 and the wedge cutter block 13 to disengage from the die 14, thus exposing the formed sheet metal. The formed sheet metal is then unloaded by the material handling mechanism 10. The connecting head 16 is connected to an external air pump, which provides power to the telescopic cylinder 105 via the external air pump and air supply pipe 17. This power supply drives the telescopic cylinder 105 to move the U-shaped connector 106. The movement of the U-shaped connector 106 drives the connecting plate 107 to rotate on its inner wall. The rotation of the connecting plate 107 drives the support block 1... When 1031 rotates, the support block 1031 and the support block 2 1032 are connected by screws. The support block 1031 and the support block 2 1032 are installed with the support rod 102 through the positioning groove 1030. Thus, the rotation of the support block 1031 drives the support rod 102 to rotate through the support block 2 1032 and the positioning groove 1030. The rotation of the support block 1031 drives the rod body 1033 to rotate. The rod body 1033 rotates upward to lift the molded plate and pick up the material, which facilitates the automatic picking of the molded plate and effectively improves the practicality and convenience of the device.
