Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to a metal pipe stamping equipment for a shoe rack. Background Art

[0002] Existing metal shoe cabinets generally use metal pipes as brackets, and cooperate with wire mesh or wooden boards to form a support surface for placing shoes. In order to strengthen the strength of the bracket, inclined pipes are usually arranged in an X-shape between the main support pipes on both sides. The middle parts of the two inclined pipes are usually connected by bolts, nuts and other connectors to further strengthen the strength. In order to make the connection between the inclined pipes more stable, it is usually necessary to flatten and punch the middle part of the inclined rod, so that the contact surface of the two inclined rod brackets is larger. Most of the existing stamping is done manually, which is inefficient and labor-intensive. Therefore, a new type of stamping equipment is needed to solve this problem. Summary of the invention

[0003] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a metal pipe stamping device for a shoe rack.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a metal pipe stamping equipment for shoe racks, comprising a frame, the frame is rotatably connected to a support platform, the frame is provided with a power mechanism for driving the support platform to rotate, the support platform has four identical processing surfaces, the support platform is slidably connected to a tool holder on each of the processing surfaces, a punching head is fixedly connected to the tool holder, the frame is provided with a tool holder driving mechanism for driving the tool holder to slide, a placement groove is provided on each of the processing surfaces of the support platform, and a baffle is provided at one end of the placement groove. The other end of the placement groove has an opening for the pipe to fall out, and each of the placement grooves is provided with a clamping mechanism for limiting the position of the pipe. The support table is provided with a chip removal groove below each of the placement grooves, and the placement groove is provided with a through hole for the punch head to pass through. The frame is provided with a loading mechanism at the processing surface at the top of the support table, and the frame is provided with a release mechanism for driving the clamping mechanism to release the fixation at the processing surface at the top of the support table. The tool holder driving mechanism is located at the processing surface on the other side of the support table.

[0006] By adopting the above technical solution, the rotation of the support table is used to drive each processing surface to change the work station. The feeding mechanism is arranged on the top of the support table. The processing surface at the top is a horizontal plane that can support the pipe falling from the feeding mechanism. After rolling out of the feeding mechanism, the pipe will fall into the placement groove and then be clamped by the clamping mechanism so that it can only slide along its own axial direction. Then the power mechanism drives the support table to rotate once, so that the working surface with the pipe fittings moves to the side. After moving to the side, the pipe fittings will abut against the baffle under the action of their own weight to complete the final positioning. Then the tool holder driving mechanism will drive the tool holder to move downward so that the punching head punches the pipe fittings. The punching head includes a punching knife and a slidable punching head. There is a spring between the punching head and the punching knife. During the pressing process, the pressure head will first flatten the pipe fitting, and then the punching knife will slide out of the pressure head to punch the flattened part of the pipe fitting and complete the stamping. During the stamping process, the punching knife on the punching head will carry the waste chips through the through hole and leave the waste chips in the chip groove. Since the chip groove is in a vertical state at this time, the waste chips will be discharged from the waste chip groove under the action of its own weight. Then the pipe fitting will come to the other side of the support table with the two rotations of the support table. In this process, since the baffle no longer blocks the pipe fitting, the pipe fitting will fall out of the opening of the placement groove under the action of its own weight during the rotation, thereby realizing automatic loading and unloading and processing of the pipe fitting, and utilizing the position change caused by the rotation of the support table to make the pipe fitting and the waste chips generated by the processing able to be adjusted or discharged by their own weight, and the structure is relatively simple.

[0007] Preferably, the power mechanism includes a power motor, a toothless gear and a transmission gear, the support platform is rotatably connected to the frame via a drive shaft, the frame is rotatably connected with a transmission shaft, the drive shaft and the transmission shaft are connected via a belt transmission, the power motor is fixedly connected to the frame, the toothless gear is transmission-connected to the output shaft of the power motor, the transmission gear is transmission-connected to the transmission shaft, and the transmission gear and the toothless gear are meshed. The present invention utilizes the intermittent meshing of the toothless gear and the transmission gear so that the support platform can intermittently rotate at a fixed angle, the power of the toothless gear is provided by the power motor, and then the toothless gear transmits the rotation to the transmission gear, and the transmission gear transmits the rotation to the rotating shaft via the transmission shaft and the belt, thereby realizing the driving of the support platform.

[0008] Preferably, the clamping mechanism includes two L-shaped pressing pieces, a V-shaped groove is provided on the inner side of the L-shaped pressing piece, the L-shaped pressing piece is slidably connected to the support platform, an elastic piece 1 is provided between the L-shaped pressing piece and the support platform, and the support platform is provided with a pushing mechanism for driving the two L-shaped pressing pieces in each clamping mechanism to loosen the pipe fittings. The present invention utilizes an elastic piece to enable the L-shaped pressing piece to maintain contact with the support platform, so that the pipe fitting is limited in the V-shaped groove, and the self-centering effect of the V-shaped groove makes it impossible for the pipe fitting to move forward, backward, up and down, and can only move left and right along its own axis to achieve the fixation of the pipe fitting. The pushing mechanism can drive the L-shaped pressing piece to overcome the sliding of the elastic piece 1 to separate it from the support platform, forming a spacing for the pipe fitting to slide into, so as to achieve the feeding of the pipe fitting, and the pushing mechanism is driven by the release mechanism.

[0009] Preferably, the pushing mechanism includes two driving blocks and a connecting plate, the two driving blocks are slidably connected to the support platform, the two driving blocks are respectively abutted against the two L-shaped pressure pieces, the driving blocks and the L-shaped pressure pieces are provided with inclined surfaces at the abutting points, the two driving blocks are abutted against the connecting plates, the two driving blocks are fixedly connected to the connecting plates, and the releasing mechanism is a cylinder 1, the cylinder 1 is fixedly connected to the frame, and the output rod of the cylinder 1 is abutted against one of the connecting plates. The present invention utilizes the inclined surface between the driving block and the L-shaped pressure piece, and pushes the connecting plate by extending the output rod of the cylinder 1, so that the connecting plate drives the two driving blocks to slide, and drives the two L-shaped pressure pieces to slide upward through the inclined surface, thereby generating a gap for the pipe fittings to enter, and the cylinder 1 is controlled by an electromagnetic reversing valve.

[0010] Preferably, the feeding mechanism includes a hopper, a guide pipe, a feeding roller and a guide plate, the hopper is fixedly connected to the frame, the guide pipe is fixedly connected at the outlet of the hopper, the outlet of the guide pipe is located above the feeding roller, the feeding roller is provided with a plurality of grooves, one of the grooves is aligned with the outlet of the guide pipe, the feeding roller is rotatably connected to the frame, the frame is fixedly connected with a servo motor for driving the feeding roller to rotate, the guide plate is obliquely arranged between the feeding roller and the support platform, the guide plate is fixedly connected to the frame, a slope is arranged on one side of the placement groove, and the slope and the guide plate are connected with each other. The present invention utilizes a hopper to store pipe blanks. The hopper is in an inverted cone shape. The pipe fittings will continuously enter the guide pipe under the action of their own weight. After falling out of the guide pipe, the pipe fittings will enter the groove of the feeding roller. The distance between the bottom of the groove of the feeding roller and the guide pipe is only enough for one pipe fitting to pass through. When the feeding roller rotates under the drive of the servo motor, only the pipe fittings in the groove will be brought out, and other pipe fittings above the pipe fittings will abut against the feeding roller until the next groove enters the bottom of the guide pipe. Each time the servo motor is started, it will only rotate a certain angle so that the groove faces the guide plate. At this time, the pipe fittings will enter the placement groove along the inclined guide plate and the slope connected to the guide plate, thereby realizing the feeding function.

[0011] Preferably, a curved plate is fixedly connected to one side of the guide pipe. The present invention utilizes the curved plate to prevent the pipe from flying out during the rotation of the feeding roller, thereby ensuring that the pipe enters the placement groove in a horizontal manner.

[0012] Preferably, the guide pipe is provided with a material-dispensing opening, the guide pipe is rotatably connected to a material-dispensing plate at the material-dispensing opening, and the frame is provided with a reciprocating mechanism for driving the material-dispensing plate to reciprocate. The present invention utilizes a reciprocating mechanism to drive the material-dispensing plate to reciprocate, thereby displacing the stacked pipes to destroy the force balance between them and prevent the pipes from being blocked.

[0013] Preferably, the reciprocating mechanism includes an air motor, a rotating rod and a connecting rod, the air motor is fixedly connected to the frame, one end of the rotating rod is drivingly connected to the output shaft of the air motor, the other end of the rotating rod is rotationally connected to one end of the connecting rod, and the other end of the connecting rod is rotationally connected to the material stripping plate. The present invention utilizes the air motor to drive the rotating rod to rotate continuously, and then transforms it into the reciprocating swing of the material stripping plate through the connecting rod. The air motor can release pressure through means such as a valve when the material stripping plate cannot be pushed, thereby avoiding damage to the pipe fittings and the material stripping plate.

[0014] Preferably, the tool holder driving mechanism includes a second cylinder and a second elastic member, wherein the second cylinder is fixedly connected to the frame, and the second elastic member is arranged between the tool holder and the support platform. The present invention utilizes the extension of the output rod of the second cylinder to drive the tool holder to move downward to achieve the punching of the pipe fitting, and when the output rod of the second cylinder is retracted, the second elastic member releases the elastic force to drive the tool holder to reset, and the second cylinder is controlled by an electromagnetic reversing valve.

[0015] Preferably, the frame is slidably connected with a rack, the rack is meshed with the toothless gear, the frame is slidably connected with a push rod and a pressure rod, an elastic member three is arranged between the push rod and the pressure rod, the frame is fixedly connected with a control switch for starting the release mechanism, the tool holder drive mechanism and the feeding mechanism, and the pressure rod is in contact with the control switch. The present invention, after the toothless gear is separated from the transmission gear, the toothless gear will mesh with the rack and drive the rack to slide. The sliding of the rack will push the push rod to slide. The push rod and the elastic member three intermediately push the pressure rod to slide, so that the pressure rod presses the control switch. The control switch is connected to the control circuit. When the control switch is pressed, a model number will be sent to the control circuit, so that the control circuit drives the electromagnetic reversing valve of cylinder one, the electromagnetic reversing valve of cylinder two and the servo motor to act, thereby realizing the rotation of the support platform and the sequential action between cylinder one, cylinder two and the servo motor. After the pressure rod is pressed on the control switch, the push rod will continue to squeeze the elastic member three, so that the pressure rod keeps pressing the control switch, thereby ensuring that each mechanism can complete its own action. When the toothless gear is separated from the rack, the elastic member three will release the elastic force to recover. At the same time, the spring in the control switch will also reset the control switch and cause the control circuit to act again, so that cylinder one and cylinder two are reset, while the servo motor remains stationary.

[0016] In summary, the beneficial effects of the present invention are: 1. The intermittent rotation of the support table drives the pipe fittings to switch between different workstations, realizing automatic loading, unloading and punching of the pipe fittings. At the same time, the different states of each surface of the support table in different directions enable the waste chips and pipe fittings to be adjusted and discharged by their own weight, making the structure simpler.

[0017] 2. The toothless gear cooperates with the rack, the transmission gear and the control switch to realize the sequential action between the support platform and cylinder one, cylinder two and the servo motor. The push rod, the pressure rod and the elastic part three are used to realize the delayed pressing of the control switch to ensure that each mechanism has sufficient time to complete the action.

[0018] 3. Use the hopper to store the blanks, use the guide channel to guide the blanks to the loading roller, and then realize automatic loading through the intermittent rotation of the loading roller driven by the servo motor.

[0031] As shown in Figure 1-2, a metal pipe stamping equipment for shoe racks includes a frame 1, the frame 1 is rotatably connected to a support table 2, the frame 1 is provided with a power mechanism for driving the support table 2 to rotate, the support table 2 has four identical processing surfaces 3, the support table 2 is slidably connected to a tool holder 4 on each processing surface 3, the tool holder 4 is fixedly connected to a punching head 5, the frame 1 is provided with a tool holder 4 driving mechanism for driving the tool holder 4 to slide, each processing surface 3 of the support table 2 is provided with a placement groove 6, one end of the placement groove 6 is provided with a baffle 7, and the placement groove 6 is provided with a baffle 7. The other end of the placement slot 6 has an opening 8 for the pipe to fall out, and each placement slot 6 is provided with a clamping mechanism for limiting the position of the pipe. The support table 2 is provided with a chip removal groove 9 below each placement slot 6, and the placement slot 6 is provided with a through hole 10 for the punch head 5 to pass through. The frame 1 is provided with a loading mechanism at the processing surface 3 at the top of the support table 2. The frame 1 is provided with a release mechanism for driving the clamping mechanism to release the fixation at the processing surface 3 at the top of the support table 2, and the tool holder 4 driving mechanism is located at the processing surface 3 on the other side of the support table 2.

[0032] By adopting the above technical solution, the rotation of the support table 2 is used to drive each processing surface 3 to change the working position. The feeding mechanism is arranged on the top of the support table 2. The processing surface 3 located on the top is a horizontal plane that can support the pipe falling from the feeding mechanism. After rolling out of the feeding mechanism, the pipe will fall into the placement groove 6, and then be clamped by the clamping mechanism so that it can only slide along its own axial direction. Then the power mechanism drives the support table 2 to rotate once, so that the working surface with the pipe fittings moves to the side. After moving to the side, the pipe fittings will abut against the baffle 7 under the action of their own weight to complete the final positioning. Then the tool holder 4 driving mechanism will drive the tool holder 4 to move downward so that the punching head 5 punches the pipe fittings. The punching head 5 includes a punching knife and a slidable punching head. There is a spring between the punching head and the punching knife. During the stamping process, the pressure head will first flatten the pipe fitting, and then the punching knife will slide out of the pressure head to punch the flattened part of the pipe fitting and complete the stamping. During the stamping process, the punching knife on the punching head 5 will carry the waste chips through the through hole 10 and leave the waste chips in the chip groove 9. Since the chip groove 9 is in a vertical state at this time, the waste chips will be discharged from the waste chip groove under the action of its own weight. Then the pipe fitting will come to the other side of the support table 2 with the two rotations of the support table 2. In this process, since the baffle 7 no longer blocks the pipe fitting, the pipe fitting will fall out of the opening 8 of the placement groove 6 under the action of its own weight during the rotation, thereby realizing automatic loading and unloading and processing of the pipe fitting, and utilizing the position change caused by the rotation of the support table 2 so that the pipe fitting and the waste chips generated by the processing can be adjusted or discharged by their own weight, and the structure is relatively simple.

The toothless gear 12 is transmission-connected to the output shaft of the power motor 11. The transmission gear 13 is transmission-connected to the transmission shaft 15. The transmission gear 13 and the toothless gear 12 are meshed. By utilizing the intermittent meshing of the toothless gear 12 and the transmission gear 13, the support platform 2 can intermittently rotate at a fixed angle. The power of the toothless gear 12 is provided by the power motor 11, and then the toothless gear 12 transmits the rotation to the transmission gear 13. The transmission gear 13 transmits the rotation to the rotating shaft through the transmission shaft 15 and the belt 16, thereby realizing the driving of the support platform 2.

[0034] like Figure 4As shown, the clamping mechanism includes two L-shaped pressing pieces 17, a V-shaped groove 18 is provided inside the L-shaped pressing piece 17, the L-shaped pressing piece 17 is slidably connected with the support platform 2, an elastic piece 19 is provided between the L-shaped pressing piece 17 and the support platform 2, and the support platform 2 is provided with a pushing mechanism for driving the two L-shaped pressing pieces 17 in each clamping mechanism to release the pipe fittings. The elastic piece 19 is used to make the L-shaped pressing piece 17 maintain contact with the support platform 2, so that the pipe fittings are limited in the V-shaped groove 18, and the self-centering effect of the V-shaped groove 18 makes it impossible for the pipe fittings to move forward and backward, up and down, and can only move left and right along its own axis to fix the pipe fittings. The pushing mechanism can drive the L-shaped pressing piece 17 to overcome the sliding of the elastic piece 19 to separate it from the support platform 2, forming a spacing for the pipe fittings to slide into, so as to realize the feeding of the pipe fittings, and the pushing mechanism is driven by the release mechanism.

[0035] like Figure 4 As shown, the pushing mechanism includes two driving blocks 20 and a connecting plate 21. The two driving blocks 20 are slidably connected to the support platform 2. The two driving blocks 20 are respectively in contact with two L-shaped pressing pieces 17.

The two driving blocks 20 are fixedly connected to the connecting plate 21. The releasing mechanism is a cylinder 1 22. The cylinder 1 22 is fixedly connected to the frame 1. The output rod of the cylinder 1 22 is in contact with one of the connecting plates 21. By utilizing the inclined surface between the driving block 20 and the L-shaped pressing piece 17, the connecting plate 21 is pushed by the extension of the output rod of the cylinder 1 22, so that the connecting plate 21 drives the two driving blocks 20 to slide, and drives the two L-shaped pressing pieces 17 to slide upward through the inclined surface, thereby generating a gap for the pipe fittings to enter. The cylinder 1 22 is controlled by an electromagnetic reversing valve.

The hopper 23 is used to store the pipe blanks. The hopper 23 is in an inverted cone shape. The pipes will continuously enter the guide pipe 24 under the action of their own weight. After falling out of the guide pipe 24, the pipes will enter the groove 27 of the feeding roller 25. The distance between the bottom of the groove 27 of the feeding roller 25 and the guide pipe 24 is only enough for one pipe to pass through. When the feeding roller 25 is driven by the servo motor 28 to rotate, only the pipe in the groove 27 will be brought out, and other pipes located above the pipe will abut against the feeding roller 25 until the next groove 27 enters the bottom of the guide pipe 24. Each time the servo motor 28 is started, it will only rotate a certain angle so that the groove 27 faces the guide plate 26. At this time, the pipe will follow the inclined guide plate 26 and the slope 29 connected to the guide plate 26 into the placement groove 6, thereby realizing the feeding function.

[0037] like Figure 5 As shown, a curved plate 30 is fixedly connected to one side of the guide pipe 24. The curved plate 30 is used to prevent the pipe from flying out during the rotation of the feeding roller 25, thereby ensuring that the pipe enters the placement groove 6 in a horizontal manner.

[0038] like Figure 3 and Figure 5 As shown, the guide pipe 24 is provided with a material-dispensing opening, and the guide pipe 24 is rotatably connected to a material-dispensing plate 31 at the material-dispensing opening, and the frame 1 is provided with a reciprocating mechanism for driving the material-dispensing plate 31 to reciprocate.

The air motor 32 is used to drive the rotating rod 33 to rotate continuously, and then the rotating rod 33 is transformed into a reciprocating swing of the material-diverting plate 31 through the connecting rod 34. The air motor 32 can release pressure through a valve or other means when the material-diverting plate 31 cannot be pushed, so as to avoid damage to the pipe fittings and the material-diverting plate 31.

[0040] like Figure 1 As shown, the tool holder 4 driving mechanism includes a second cylinder 35 and a second elastic member 36. The second cylinder 35 is fixedly connected to the frame 1, and the second elastic member 36 is arranged between the tool holder 4 and the support platform 2. The tool holder 4 is driven downward by the extension of the output rod of the second cylinder 35 to achieve the punching of the pipe fitting. When the output rod of the second cylinder 35 is retracted, the second elastic member 36 releases the elastic force to drive the tool holder 4 to reset. The second cylinder 35 is controlled by an electromagnetic reversing valve.

After the toothless gear 12 is separated from the transmission gear 13, the toothless gear 12 will mesh with the rack 38 and drive the rack 38 to slide. The sliding of the rack 38 will push the push rod 39 to slide. The push rod 39 pushes the pressure rod 40 to slide through the elastic member 3 41, so that the pressure rod 40 presses the control switch 37. The control switch 37 is connected to the control circuit.
