Technical Field

[0001] The present invention relates to the technical field of sheet metal stamping equipment, and discloses a stamping equipment for building sheet metal processing. Background Art

[0002] A stamping equipment is a mechanical device that uses a mold to apply an external force to a sheet metal, causing it to undergo plastic deformation or separation, thereby obtaining a workpiece with the required shape and size. It is widely used in multiple industries such as automobiles, home appliances, and construction. During the process of stamping building sheet metal by the stamping equipment, especially when the stamping equipment stamps and prints on a door panel, it is necessary to first pull out a metal sheet from a steel coil, cut off a fixed length of the metal sheet, and finally perform stamping on the metal sheet. Since the metal sheet pulled out from the steel coil is bent as a whole, when the mold stamps the metal sheet, the metal sheet will shift slightly, resulting in the shift of the stamping and printing position on the metal sheet, and reducing the processing quality of the stamping device.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the appended Figures 1-9 drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] Example 1: When the existing stamping device stamps and prints a metal sheet, since the metal sheet is stretched out from the coiled state, there is partial bending when the metal sheet is placed on a flat surface. When the metal sheet is processed by the stamping device, there will be a situation of position deviation, resulting in the deviation of the printing position on the metal sheet and the decline in the processing quality of the stamping device.

[0022] Based on this, a stamping device provided in an embodiment of the present application gradually flattens the metal sheet before stamping, and at the same time fixes it in the center in a flat state, so that the printing position on the metal sheet by the stamping device is centered, ensuring the stable quality of the sheet processed by the stamping device. Please refer to Figures 1-8 As shown in the figure, it includes: a frame 1, a sliding block 2 is slidably connected to the frame 1, a hydraulic mechanism is arranged on the frame 1, a stamping plate 4 is fixedly connected to the lower side of the sliding block 2, a die 5 is fixedly connected to the lower part of the frame 1, and the hydraulic mechanism is used to control the movement of the sliding block 2; a mirror-image sliding frame 6, which is slidably connected to the stamping plate 4, a mirror-image sliding rod 7 is slidably connected to the sliding frame 6, and the mirror-image sliding rods 7 on the same sliding frame 6 are jointly rotatably connected to a pressure roller 9 for flattening the middle of the sheet to be stamped to both sides; a buffer cylinder 8, which is the same in number as the sliding rod 7, is arranged on the upper side of the corresponding sliding rod 7, and a tension spring is fixedly connected between the buffer cylinder 8 and the corresponding sliding frame 6 for making there always be a squeezing force when the pressure roller 9 flattens the sheet to be stamped; mirror-image mounting frames 10, which are both slidably connected to the die 5, a plurality of rotating plates 11 are rotatably connected to the mounting frames 10, a plurality of support blocks 12 are fixedly connected to the mounting frames 10, the number of the rotating plates 11 is the same as the number of the support blocks 12, and a sliding bent plate 13 is slidably connected to the rotating plates 11 for flattening both sides of the sheet to be detected; a transmission mechanism, which is arranged on the stamping plate 4 for controlling the moving speed of the mirror-image sliding frame 6; mirror-image alignment mechanisms, which are respectively arranged on the corresponding mounting frames 10 for controlling the synchronous rotation of a plurality of rotating plates 11 on the same side.

[0023] In the above solution, it aims to solve the situation where the metal sheet pulled out from the steel coil is in a bent state as a whole before stamping, which causes the metal sheet to shift during stamping, resulting in the problem that the printed pattern position stamped on the metal sheet is not centered. To ensure that the pattern on the metal sheet is stamped centered and improve the quality of the device for stamping and printing on the metal sheet, this embodiment is a working mode of the device, including a frame 1. On one side of the frame 1, there is a control console (an existing mechanism, not shown). A sliding block 2 drives a stamping plate 4 to move up and down on the frame 1. A hydraulic mechanism provided on the frame 1 is used to control the movement of the sliding block 2. At the lower part of the frame 1, there is a die 5 that is fixedly connected and extrusion - cooperates with the stamping plate 4. The metal sheet is placed on the die 5 and the stamping operation is completed through the movement and extrusion of the stamping plate 4. Two power hydraulic cylinders 3 are fixedly connected to the frame 1, and the telescopic ends of the power hydraulic cylinders 3 move synchronously with the sliding block 2. The area of the die 5 is larger than the area of the stamping plate 4. The upper side of the support block 12 is flush with the upper side of the die 5. The sliding bent plate 13 is L - shaped and is used to swing the sliding bent plate 13 downward to flatten the edge of the metal sheet. At the same time, the sliding bent plate 13 cooperates with the corresponding support block 12 to fix the metal sheet. The alignment mechanism, hydraulic mechanism, and fixing mechanism are all electrically connected to the control console.

[0024] The working process is as follows: First, the operator places the metal sheet to be stamped on the die 5. Then, the operator starts the hydraulic mechanism through the control console. The sliding block 2 drives the stamping plate 4 and the parts connected thereto to move downward synchronously. Two pressure rollers 9 contact and squeeze the middle part of the metal sheet. The telescopic ends of the power hydraulic cylinders 3 extend as the sliding block 2 moves. The power hydraulic cylinders 3 make the two sliding frames 6 move away from each other through the hydraulic oil in them and the transmission mechanism. The pressure rollers 9 roll on the metal sheet, and the metal sheet is gradually flattened from the middle to both sides. During the movement of the sliding block 2, the pressure rollers 9 contact and squeeze the metal sheet, and the sliding frames 6 move downward relative to the corresponding sliding rods 7. The sliding frames 6 stretch the tension springs connected to them. The tension of the tension springs keeps the pressure rollers 9 pressing on the metal sheet through the corresponding sliding rods 7 and buffer cylinders 8. When the stamping plate 4 is about to contact and squeeze the metal sheet, the two pressure rollers 9 leave the stamping range of the stamping plate 4. At this time, the pressure rollers 9 are only a short distance away from the edge of the adjacent metal sheet, achieving the purpose of quickly flattening the middle part of the metal sheet, making the metal sheet fit with the die 5, and ensuring the stability of the metal sheet during stamping.

[0025] When the pressure roller 9 leaves the stamping range of the stamping plate 4, the control console swings all the rotating plates 11 downward through the alignment mechanism. During the downward swinging of the rotating plate 11, the sliding bent plate 13 first flattens the edge of the metal sheet and cooperates with the support block 12 to press the edge of the metal sheet downward. When the rotating plate 11 reaches the limit, the alignment mechanism controls the corresponding sliding bent plate 13 in the rotating plate 11 to slide downward, and the sliding bent plate 13 flattens the edge of the metal sheet. At the same time, the sliding bent plate 13 cooperates with the corresponding support block 12 to fix the edge of the metal sheet. Then the alignment mechanism is closed. At this time, the surface of the metal sheet is completely flattened, and then the two mounting frames 10 are pushed. The two mounting frames 10 are close to each other. The two mounting frames 10 push the left and right sides of the metal sheet at the same time through the sliding bent plate 13 and the support block 12 to change the stamping position of the metal sheet. If the metal sheet is not centered on the die 5, the metal sheet moves to the center, and the pressure roller 9 rotates while maintaining the extrusion force on the metal sheet to assist the movement of the metal sheet. At this point, the adjustment of the position of the metal sheet is completed, ensuring that the stamping plate 4 is centered in the stamping and printing position on the metal sheet.

[0026] When the metal sheet is moving, the sliding block 2 is still moving down slowly, and the stamping plate 4 gradually approaches the metal sheet. When the two mounting frames 10 are moved, the metal sheet is centered. Then the sliding block 2 drives the stamping plate 4 to cooperate with the die 5 to contact and extrude the metal sheet, and the metal sheet is stamped and printed. When the stamping of the metal sheet is completed, the console controls the sliding block 2 to drive the connected parts to reset through the hydraulic mechanism, and the telescopic end of the power hydraulic cylinder 3 is retracted, and the transmission mechanism controls the corresponding sliding frame 6 to move and reset. The relative position of the sliding rod 7 and the sliding frame 6 moves and resets under the tension of the tension spring connected to the buffer cylinder 8, and the force storage component drives the corresponding mounting frame 10 to move and reset. Finally, the alignment mechanism controls the rotating plate 11 to swing and reset, and the sliding bent plate 13 moves and resets relative to the rotating plate 11. At this point, all parts in the device are restored to their initial positions. After the operator takes away the metal sheet that has been stamped, he replaces it with the next one until all the work of the device is completed. The operator can turn off the power of the device.

[0027] Please refer to Figure 3 and Figure 4 As shown, the transmission mechanism includes: a plurality of transmission hydraulic cylinders 201, all of which are fixedly connected to the stamping plate 4, a plurality of power hydraulic cylinders 3 are fixedly connected to the frame 1, the telescopic ends of the power hydraulic cylinders 3 are fixedly connected to the sliding block 2, the number of the power hydraulic cylinders 3 is the same as the number of the transmission hydraulic cylinders 201, one side of the transmission hydraulic cylinder 201 is connected with a guide pipe 202, the guide pipe 202 is connected to the adjacent power hydraulic cylinder 3, the guide pipe 202 is used to control the moving speed of the sliding frame 6 according to the moving speed of the sliding block 2, the maximum length of movement of the telescopic end of the transmission hydraulic cylinder 201 is greater than half the length of the stamping plate 4, and is used to make the pressure roller 9 out of the stamping range of the stamping plate 4.

[0028] In the above solution, it is aimed to control the moving distance of the sliding frame 6 according to the movement of the sliding block 2, so that before the stamping plate 4 is about to contact the metal sheet, the pressing roller 9 leaves the stamping range of the stamping plate 4, ensuring that the pressing roller 9 does not interfere with the stamping operation of the stamping plate 4 during the process of flattening the middle part of the metal sheet, enabling the device to synchronously complete the operation of flattening and centering the metal sheet during the normal stamping process, ensuring the normal working speed of the device while achieving an additional alignment effect. Taking the front-side drive hydraulic cylinder 201 as an example, when the sliding block 2 moves and the telescopic end of the power hydraulic cylinder 3 extends, the hydraulic oil in the power hydraulic cylinder 3 enters the left side inside the drive hydraulic cylinder 201 through the diversion pipe 202. The telescopic end of the drive hydraulic cylinder 201 extends and drives the right-side sliding frame 6 to move to the right, while the left-side sliding frame 6 moves to the left.

[0029] Please refer to Figure 7 and Figure 8 As shown, the alignment mechanism includes: electric push rods 301, the same number as the rotating plates 11, hinged to the upper side of the corresponding mounting frames 10. A plurality of blind holes are provided inside the mounting frames 10. The telescopic end of the electric push rod 301 is fixedly connected with an elastic hydraulic cylinder 303. The telescopic end of the elastic hydraulic cylinder 303 is hinged to the adjacent rotating plate 11. The electric push rod 301 is used to control the rotation range of the rotating plate 11; push hydraulic cylinders 304, the same number as the rotating plates 11, fixedly connected to the corresponding rotating plates 11. The push hydraulic cylinders 304 are communicated with the corresponding elastic hydraulic cylinders 303 through pipes. The telescopic end of the push hydraulic cylinder 304 is fixedly connected with the adjacent sliding bent plate 13, and is used to control the relative movement between the rotating plate 11 and the corresponding sliding bent plate 13; rotating rollers 302, rotatably connected between all the sliding bent plates 13 on the adjacent mounting frames 10. The rotating rollers 302 are used to assist in flattening the edges of the sheet to be stamped; mirror-image energy storage components, both arranged on the frame 1. The energy storage components are used to control the movement of the corresponding mounting frames 10 to center the stamping position of the sheet to be stamped. The rotating rollers 302 are tangent to the lower sides of all the sliding bent plates 13 on the adjacent mounting frames 10, and are used to assist in flattening the sheet to be stamped in the horizontal direction. The distance between the rotation axis of the rotating plate 11 and the rotation axis of the adjacent rotating roller 302 is smaller than the distance between it and the adjacent support block 12 in the vertical direction, so as to enable the edge of the metal sheet to smoothly enter between the sliding bent plate 13 and the adjacent support block 12.

[0030] In the above solution, it is aimed to actively control the synchronous rotation of all the rotating plates 11, so that after the pressing roller 9 leaves the stamping range of the stamping plate 4, the rotating plate 11 drives the sliding bending plate 13 to swing and flatten the edge of the metal plate, thereby achieving the purpose of fully flattening the metal plate, making the metal plate fully flattened before being centered and fixed on the die 5, ensuring that the metal plate does not bend when pushing the edges on both sides of the metal plate subsequently. Only when the metal plate is in a flattened state can the edges on both sides of the metal plate be pushed without bending the metal plate. After the pressing roller 9 leaves the stamping range of the stamping plate 4, the control console starts the electric push rod 301. The telescopic end of the electric push rod 301 extends. The rotating plate 11 swings and makes the sliding bending plate 13 drive the rotating roller 302 to swing downward. When the rotating plate 11 swings downward to the vertical state, it stops. The telescopic end of the electric push rod 301 continues to extend. The elastic hydraulic cylinder 303 at the telescopic end of the electric push rod 301 is compressed. The telescopic end of the elastic hydraulic cylinder 303 retracts. The hydraulic oil in the elastic hydraulic cylinder 303 flows into the corresponding pushing hydraulic cylinder 304 through the pipeline. When the telescopic end of the pushing hydraulic cylinder 304 extends, the corresponding sliding bending plate 13 slides downward relative to the corresponding rotating plate 11. The sliding bending plate 13 and the rotating roller 302 jointly press the edge of the metal plate downward (regardless of whether the metal plate is bent upward or downward at this time, the edge of the metal plate is pushed downward and flattened). Finally, the lower side of the sliding bending plate 13 cooperates with the support block 12 to fix and keep the metal plate flat. The electric push rod 301 is closed. When the subsequent two mounting frames 10 approach each other to center the metal plate, the metal plate slides between the sliding bending plate 13 and the corresponding support block 12, and the rotating roller 302 assists in rotating. After the metal plate is stamped, the control console controls the telescopic end of the electric push rod 301 to retract. The telescopic end of the elastic hydraulic cylinder 303 extends. The telescopic end of the pushing hydraulic cylinder 304 contracts and drives the corresponding sliding bending plate 13 to return to the initial position with the rotating plate 11. Finally, as the telescopic end of the electric push rod 301 continues to contract, the rotating plate 11 swings back to the initial position.

[0031] Please refer to Figures 2-4 and Figures 6-9 As shown in, the energy storage assembly includes: a fixed hydraulic cylinder 401, fixedly connected to the frame 1. A spring is fixedly connected between the telescopic end of the fixed hydraulic cylinder 401 and the adjacent mounting frame 10. The fixed hydraulic cylinder 401 is communicated with a liquid guide pipe 402. The liquid guide pipe 402 is communicated with the other side of one of the transmission hydraulic cylinders 201. The fixed hydraulic cylinder 401 is used to control the movement of the corresponding mounting frame 10; a plurality of limit blocks 403, respectively slidably connected in the corresponding blind holes of the corresponding mounting frames 10. Springs are fixedly connected between the limit blocks 403 and the corresponding mounting frames 10. The limit blocks 403 are in extrusion fit with the die 5. The limit blocks 403 are used to limit the timing of the movement of the corresponding mounting frame 10.

[0032] Please refer to Figure 9As shown, the force storage assembly also includes: multiple pull ropes 501, all of which are slidably connected to the corresponding mounting frame 10, one end of the pull rope 501 is fixedly connected to the adjacent limit block 403, and the other end of the pull rope 501 is fixedly connected to the adjacent rotating plate 11. The pull rope 501 is used to control the moving distance of the limit block 403. The length change of the pull rope 501 outside the corresponding mounting frame 10 is equal to the length of the limit block 403 located on the outer part of the corresponding mounting frame 10, which is used to release the limit of the limit block 403 after the rotating plate 11 rotates to the limit.

[0033] In the above scheme, the purpose is to control the timing of the movement of the mounting frame 10 so that the metal sheet can be moved and centered after the surface is flattened, so as to avoid the problem that the metal sheet is not completely flattened, and the two mounting frames 10 start to push the edges of the metal sheet to center it, resulting in bending and deformation of the metal sheet, affecting the smooth progress of the stamping process of the device, and finally ensuring the smooth progress of the alignment process of the device. Taking the fixed hydraulic cylinder 401 on the right as an example, when the telescopic end of the front transmission hydraulic cylinder 201 drives the sliding frame 6 to move to the right, the hydraulic oil in the transmission hydraulic cylinder 201 enters the fixed hydraulic cylinder 401 through the liquid guide tube 402, and the telescopic end of the fixed hydraulic cylinder 401 extends, and the spring connected to the telescopic end of the fixed hydraulic cylinder 401 is compressed and stored, and then the rotating plate 11 swings downward and is pulled The rope 501 drives the limit block 403 to move, and the limit block 403 gradually enters the corresponding mounting frame 10. When the rotating plate 11 swings downward to vertical, the limit block 403 completely enters the corresponding mounting frame 10, and the limit block 403 releases the limit of the mounting frame 10. The mounting frame 10 pushes the edge of the metal sheet through the rotating plate 11, the sliding bent plate 13 and the support block 12 thereon to center the metal sheet. When the stamping of the metal sheet is completed, the sliding block 2 moves and resets, the telescopic end of the fixed hydraulic cylinder 401 contracts and drives the mounting frame 10 to reset through the spring. When the rotating plate 11 swings upward, the pull rope 501 relaxes, and the limit block 403 moves and resets under the elastic force of the connected spring, and the pull rope 501 returns to its initial state. At this point, all parts have returned to their initial positions.

[0034] In the above-mentioned embodiment, the connection relationship between the sliding rod 7 and the corresponding buffer tube 8 can be regarded as a fixed connection. However, in the following embodiments, the connection relationship between the sliding rod 7 and the corresponding buffer tube 8 is a sealed sliding connection.

[0035] Embodiment 2: In order to further improve the control over the force of the pressure roller 9 contacting and extruding the metal sheet, and avoid the problem that the pressure roller 9 squeezes the metal sheet too much, causing deformation of the metal sheet, the surface of the metal sheet remains flat during the flattening process of the metal sheet by the device, thereby ensuring the safety of the metal sheet and the stamping quality of the device.

[0036] Based on Example 1, please refer to Figure 4 and Figure 5As shown, it also includes: a mirror image fixing sleeve 601, which is fixedly connected to the corresponding sliding frame 6, a through hole is set on the side wall of the buffer cylinder 8, the fixing sleeve 601 is sealed and matched with the through hole on the corresponding buffer cylinder 8, the sliding rod 7 is sealed and slidably connected with the corresponding buffer cylinder 8, the part of the sliding rod 7 located in the corresponding buffer cylinder 8 is set with a through hole, a one-way valve is set in the through hole of the sliding rod 7, and the fixing sleeve 601 is used to limit the maximum extrusion pressure between the pressure roller 9 and the plate to be punched.

[0037] In the above scheme, the problem that the pressure roller 9 exerts too much pressure on the metal sheet, which easily causes the metal sheet to be compressed and deformed, is solved. The maximum pressure of the pressure roller 9 in contact with and extrude the metal sheet is limited to ensure the safety of the metal sheet and the flatness of the surface during the flattening process. The one-way valve in the through hole of the sliding rod 7 only allows external gas to enter the corresponding buffer cylinder 8. When the pressure roller 9 contacts and extrude the metal sheet, the sliding frame 6 corresponds to the sliding rod 7. The sliding frame 6 drives the buffer cylinder 8 to move through the tension spring. The sliding rod 7 moves into the corresponding buffer cylinder 8 and compresses the gas. The fixed sleeve 601 slides relative to the corresponding buffer cylinder 8. In this process, the tension of the tension spring connected to the buffer cylinder 8 represents the extrusion force of the pressure roller 9 on the metal sheet. When the tension spring connected to the buffer cylinder 8 is stretched to a set length, the fixed sleeve 601 releases the adjacent The through holes on the side walls of the buffer cylinder 8 are blocked, the gas in the buffer cylinder 8 is slowly discharged, the sliding rod 7 moves into the corresponding buffer cylinder 8, and the fixed sleeve 601 blocks the through holes on the side walls of the buffer cylinder 8 again. Then, the operation of opening and blocking the through holes on the side walls of the buffer cylinder 8 is repeated continuously, so that the extrusion pressure of the metal sheet by the pressure roller 9 is kept at a maximum value, thereby ensuring the safety of the metal sheet and preventing the metal sheet from being deformed and damaged due to excessive extrusion pressure. When the sliding block 2 moves to reset, the buffer cylinder 8 restores its initial relative position with the sliding frame 6 under the tension of the connected tension spring, and the pressure roller 9 and the two corresponding sliding rods 7 move downward under the action of gravity. The sliding rod 7 moves downward from the corresponding buffer cylinder 8 to reset, and the external gas is replenished into the corresponding buffer cylinder 8 through the one-way valve in the through hole of the sliding rod 7. At this point, all parts have returned to their initial positions.
