Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a stamping equipment for metal pipes used in shoe racks. Background Art

[0002] Existing metal shoe cabinets generally use metal pipes as supports, and are combined with wire meshes or wooden boards to form a support surface for placing shoes. In order to strengthen the strength of the supports, inclined pipes arranged in an X shape are usually provided between the main support pipes on both sides, and the middle parts of the two inclined pipes are usually connected by connecting parts such as bolts and nuts 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 surfaces of the two inclined rod supports are larger. Most of the existing stamping operations are manually operated, with low efficiency and high labor consumption. 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 specification, and will become partially obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the specification and other specification drawings.

[0004] The objective of the present invention is to overcome the above deficiencies and provide a stamping equipment for metal pipes used in shoe racks.

[0005] To achieve the above objective, the technical solution of the present invention is: a stamping equipment for metal pipes used in shoe racks, including a frame, the frame is rotatably connected with a support table, the frame is provided with a power mechanism for driving the support table to rotate, the support table has four identical processing surfaces, a tool holder is slidably connected to each of the processing surfaces of the support table, a stamping head is fixedly connected to each of the tool holders, the frame is provided with a tool holder driving mechanism for driving the tool holder to slide, a placement groove is opened on each of the processing surfaces of the support table, a baffle is provided at one end of the placement groove, and an opening for the pipe to fall out is provided at the other end of the placement groove. A clamping mechanism for limiting the pipe is provided in each of the placement grooves, a chip discharge groove is opened below each of the placement grooves of the support table, a through hole for the stamping head to pass through is opened in the placement groove, a feeding mechanism is provided at the processing surface of the support table at the top of the frame, a release mechanism for driving the clamping mechanism to release the fixation is provided at the processing surface of the support table at the top of the frame, and 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 members. A V-shaped groove is formed inside the L-shaped pressing member. The L-shaped pressing member is slidably connected to the support table. An elastic member I is provided between the L-shaped pressing member and the support table. The support table is provided with a pushing mechanism for driving the two L-shaped pressing members in each clamping mechanism to release the pipe fitting respectively. In the present invention, the elastic member I enables the L-shaped pressing member to maintain contact with the support table, so that the pipe fitting is limited in the V-shaped groove of the limiting groove. Due to the self-centering effect of the V-shaped groove, the pipe fitting cannot move forward, backward, up or down, and can only move left and right along its own axis to realize the fixation of the pipe fitting. The pushing mechanism can drive the L-shaped pressing member to slide against the elastic member I to separate it from the support table, forming a gap for the pipe fitting to slide in, so as to realize the feeding of the pipe fitting. The pushing mechanism is driven by a releasing mechanism.

[0009] Preferably, the pushing mechanism includes two driving blocks and a connecting plate. Both of the two driving blocks are slidably connected to the support table. The two driving blocks are respectively in contact with the two L-shaped pressing members. Bevels are provided at the contact positions of the driving block and the L-shaped pressing member. Both of the two driving blocks are in contact with the connecting plate and fixedly connected to the connecting plate. The releasing mechanism is a cylinder I, and the cylinder I is fixedly connected to the frame. The output rod of the cylinder I is in contact with one of the connecting plates. In the present invention, by using the bevel between the driving block and the L-shaped pressing member, when the output rod of the cylinder I extends to push the connecting plate, the connecting plate drives the two driving blocks to slide, and the two L-shaped pressing members are driven to slide upward through the bevel, so as to generate a gap for the pipe fitting to enter. The cylinder I 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 rest driving mechanism includes a second cylinder and a second elastic member. The second cylinder is fixedly connected to the machine frame, and the second elastic member is arranged between the tool rest and the support table. In the present invention, the extension of the output rod of the second cylinder drives the tool rest to move downward to realize the stamping of the pipe fitting. When the output rod of the second cylinder retracts, the second elastic member releases elastic force to drive the tool rest to reset. The second cylinder is controlled by an electromagnetic reversing valve.

[0015] Preferably, a rack is slidably connected to the machine frame. The rack meshes with the toothless gear. A push rod and a pressure rod are slidably connected to the machine frame. An elastic member III is arranged between the push rod and the pressure rod. The machine frame is fixedly connected with a control switch for starting the unlocking mechanism, the tool rest driving mechanism, and the feeding mechanism. The pressure rod abuts against the control switch. After the toothless gear is separated from the transmission gear in the present invention, 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 uses the elastic member III as an intermediary to 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 signal will be sent to the control circuit, so that the control circuit drives the electromagnetic reversing valves of the first cylinder and the second cylinder and the servo motor to act, so as to realize the sequential actions between the rotation of the support table and the first cylinder, the second cylinder, and the servo motor. After the pressure rod presses on the control switch, the push rod will continue to squeeze the elastic member III, so that the pressure rod keeps pressing the control switch, so as to ensure that each mechanism can complete its respective actions. When the toothless gear is separated from the rack, the elastic member III will release elastic force to restore, and at the same time, the spring in the control switch will also reset the control switch, and make the control circuit act again, so that the first cylinder and the second cylinder are reset, while the servo motor remains stationary.

[0016] In summary, the beneficial effects of the present invention are as follows:

[0017] 1. By using the intermittent rotation of the support table to drive the pipe fitting to switch between different stations, automatic feeding, discharging, and stamping of the pipe fitting are realized. At the same time, due to the different states of each surface of the support table in different orientations, the waste chips and the pipe fitting can be adjusted and discharged by their own weights, making the structure simpler.

[0018] 2. By using the mutual cooperation of the toothless gear, the rack, the transmission gear, and the control switch to realize the sequential actions between the support table and the first cylinder, the second cylinder, and the servo motor, and by using the push rod, the pressure rod, and the elastic member III to realize the delayed pressing of the control switch, ensuring that each mechanism has sufficient time to complete the action.

[0019] 3. By using the hopper to store the blanks, using the guiding channel to guide the blanks onto the feeding roller, and then through the intermittent rotation of the feeding roller driven by the servo motor, automatic feeding is realized.

[0038] As shown in Figures 1 - 2, a metal pipe stamping device for a shoe rack 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. A tool holder 4 is slidably connected to each processing surface 3 of the support table 2. A stamping head 5 is fixedly connected to each tool holder 4. The frame 1 is provided with a tool holder driving mechanism for driving the tool holder 4 to slide. A placement groove 6 is formed on each processing surface 3 of the support table 2. One end of the placement groove 6 is provided with a baffle 7, and the other end of the placement groove 6 has an opening 8 for the pipe to fall out. A clamping mechanism for limiting the pipe is arranged in each placement groove 6. A chip removal groove 9 is formed under each placement groove 6 of the support table 2. A through hole 10 for the stamping head 5 to pass through is formed in the placement groove 6. The frame 1 is provided with a feeding mechanism at the processing surface 3 of the support table 2 at the top. The frame 1 is provided with a release mechanism for driving the clamping mechanism to release the fixation at the processing surface 3 of the support table 2 at the top. The tool holder driving mechanism is located at the processing surface 3 on the other side of the support table 2.

[0039] 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.

[0040] like Figure 3 As shown, the power mechanism includes a power motor 11, a toothless gear 12 and a transmission gear 13. The support platform 2 is rotatably connected to the frame 1 through a drive shaft 14. The frame 1 is rotatably connected with a transmission shaft 15. The drive shaft 14 and the transmission shaft 15 are transmission-connected through a belt 16. The power motor 11 is fixedly connected to the frame 1. 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.

[0041] like Figure 4As shown in the figure, the clamping mechanism includes two L-shaped pressing members 17. A V-shaped groove 18 is formed inside the L-shaped pressing member 17. The L-shaped pressing member 17 is slidably connected to the support table 2. An elastic member 19 is provided between the L-shaped pressing member 17 and the support table 2. The support table 2 is provided with a pushing mechanism for driving the two L-shaped pressing members 17 in each clamping mechanism to release the pipe fitting. The elastic member enables the L-shaped pressing member 17 to maintain contact with the support table 2, so that the pipe fitting is limited in the V-shaped groove 18. Due to the self-centering effect of the V-shaped groove 18, the pipe fitting cannot move forward, backward, up or down, and can only move left and right along its own axis to realize the fixation of the pipe fitting. The pushing mechanism can drive the L-shaped pressing member 17 to slide against the elastic member 19 to separate it from the support table 2, forming a gap for the pipe fitting to slide in, so as to realize the feeding of the pipe fitting. The pushing mechanism is driven by a releasing mechanism.

[0042] As Figure 4 shown, the pushing mechanism includes two driving blocks 20 and a connecting plate 21. The two driving blocks 20 are both slidably connected to the support table 2. The two driving blocks 20 are respectively in contact with the two L-shaped pressing members 17. The driving block 20 and the L-shaped pressing member 17 are provided with inclined surfaces at the contact position. The two driving blocks 20 are both in contact with the connecting plate 21. The two driving blocks 20 are both fixedly connected to the connecting plate 21. The releasing mechanism is a cylinder 22. The cylinder 22 is fixedly connected to the frame 1. The output rod of the cylinder 22 is in contact with one of the connecting plates 21. By using the inclined surface between the driving block 20 and the L-shaped pressing member 17, the connecting plate 21 is pushed by the extension of the output rod of the cylinder 22, so that the connecting plate 21 drives the two driving blocks 20 to slide, and the two L-shaped pressing members 17 are driven to slide upward through the inclined surface, thereby generating a gap for the pipe fitting to enter. The cylinder 22 is controlled by an electromagnetic directional valve.

[0043] As Figure 3-5As shown in the figure, the feeding mechanism includes a hopper 23, a guiding pipe 24, a feeding roller 25 and a guiding plate 26. The hopper 23 is fixedly connected to the frame 1. The guiding pipe 24 is fixedly connected to the outlet of the hopper 23. The outlet of the guiding pipe 24 is located above the feeding roller 25. The feeding roller 25 is provided with a number of grooves 27, and one of the grooves 27 is aligned with the outlet of the guiding pipe 24. The feeding roller 25 is rotatably connected to the frame 1. The frame 1 is fixedly connected with a servo motor 28 for driving the feeding roller 25 to rotate. The guiding plate 26 is obliquely arranged between the feeding roller 25 and the support table 2. The guiding plate 26 is fixedly connected to the frame 1. One side of the placing groove 6 is provided with a slope 29, and the slope 29 is connected to the guiding plate 26. The hopper 23 is used to store the pipe fittings blanks. The hopper 23 is in an inverted conical shape. The pipe fittings will continuously enter the guiding pipe 24 under the action of their own gravity. After the pipe fittings fall out of the guiding pipe 24, they 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 guiding pipe 24 only allows one pipe fitting to pass through. When the feeding roller 25 rotates driven by the servo motor 28, only the pipe fitting in the groove 27 will be taken out, and the other pipe fittings located above this pipe fitting will abut against the feeding roller 25 until the next groove 27 enters below the guiding pipe 24. Each time the servo motor 28 starts, it will only rotate a certain angle, so that the groove 27 faces the guiding plate 26. At this time, the pipe fitting will enter the placing groove 6 along the inclined guiding plate 26 and the slope 29 connected to the guiding plate 26, thus realizing the feeding function.

[0044] As Figure 5 shown in the figure, an arc-shaped plate 30 is fixedly connected to one side of the guiding pipe 24. The arc-shaped plate 30 is used to prevent the pipe fittings from flying out during the rotation of the feeding roller 25, so as to ensure that the pipe fittings enter the placing groove 6 in a horizontal manner.

[0045] As Figure 3 and Figure 5 shown in the figure, the guiding pipe 24 is provided with a feeding port. The guiding pipe 24 is rotatably connected with a feeding plate 31 at the feeding port. The frame 1 is provided with a reciprocating mechanism for driving the feeding plate 31 to reciprocate. The reciprocating mechanism is used to drive the feeding plate 31 to reciprocate, so as to stir the pipe fittings piled up together to break the force balance between them and prevent the pipe fittings from being blocked.

[0046] As Figure 6 shown in the figure, the reciprocating mechanism includes a pneumatic motor 32, a rotating rod 33 and a connecting rod 34. The pneumatic motor 32 is fixedly connected to the frame 1. One end of the rotating rod 33 is in transmission connection with the output shaft of the pneumatic motor 32. The other end of the rotating rod 33 is rotatably connected to one end of the connecting rod 34. The other end of the connecting rod 34 is rotatably connected to the feeding plate 31. The pneumatic motor 32 drives the rotating rod 33 to continuously rotate, and then transforms it into the reciprocating swing of the feeding plate 31 through the connecting rod 34. The pneumatic motor 32 can relieve pressure through means such as valves when the feeding plate 31 cannot be pushed, to avoid damage to the pipe fittings and the feeding plate 31.

[0047] As Figure 1 shown, the tool rest 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 rest 4 and the support table 2. The extension of the output rod of the second cylinder 35 drives the tool rest 4 to move downward to realize the stamping of the pipe fitting. When the output rod of the second cylinder 35 retracts, the second elastic member 36 releases elastic force to drive the tool rest 4 to reset. The second cylinder 35 is controlled by an electromagnetic reversing valve.

[0048] As Figure 3 and Figure 7 shown, a rack 38 is slidably connected to the frame 1. The rack 38 meshes with the toothless gear 12. A push rod 39 and a pressure rod 40 are slidably connected to the frame 1. An elastic member 41 is arranged between the push rod 39 and the pressure rod 40. The frame 1 is fixedly connected with a control switch 37 for starting the release mechanism, the tool rest 4 driving mechanism and the feeding mechanism. The pressure rod 40 abuts against the control switch 37. 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 uses the elastic member 41 as an intermediary to push the pressure rod 40 to slide, so that the pressure rod 40 presses the control switch 37. The control switch 37 is connected to the control circuit. When the control switch 37 is pressed, it will send a signal to the control circuit, so that the control circuit drives the electromagnetic reversing valves of the first cylinder 22 and the second cylinder 35 and the servo motor 28 to act, so as to realize the sequential actions among the rotation of the support table 2, the first cylinder 22, the second cylinder 35 and the servo motor 28. After the pressure rod 40 presses on the control switch 37, the push rod 39 will continue to squeeze the elastic member 41, so that the pressure rod 40 keeps pressing the control switch 37, so as to ensure that each mechanism can complete its respective actions. When the toothless gear 12 is separated from the rack 38, the elastic member 41 will release elastic force to restore, and at the same time, the spring in the control switch 37 will also reset the control switch 37, and make the control circuit act again, so that the first cylinder 22 and the second cylinder 35 are reset, while the servo motor 28 remains stationary.

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
