Description

Technical Field

[0001] The present application relates to the field of metal pipe punching technology, and in particular to an automatic punching device for metal rods. Background Art

[0002] In the manufacturing process of baby strollers, a large number of metal rods are needed as the frame. When using metal rods as the frame of a baby stroller, it is necessary to first punch holes around the metal rods so that rivets can pass through them later. In the industrial production process, an automatic metal rod punching device is used to automatically punch metal rods to increase production capacity and save labor.

[0003] The automatic punching device for metal rods mainly includes a machine platform, a mechanical claw and a plurality of punching mechanisms, wherein the mechanical claw and the plurality of punching mechanisms are installed on the machine platform, and a plurality of limit columns are installed on the machine platform, and the plurality of limit columns are arranged at intervals along the axial direction of the metal rod, and a limit groove is provided at the top of the limit column, and the limit groove is used to accommodate the circumference of the metal rod. An automatic metal rod loading platform is provided at the feeding place of the machine platform, and a metal rod discharge collection trough is provided at the discharge place of the machine platform. When punching a metal rod, start the mechanical claw and the automatic feeding platform for metal rods, the automatic feeding platform for metal rods pushes the horizontally placed metal rod to the specified position, the mechanical claw grabs the metal rod that the automatic feeding platform for metal rods pushes to the specified position, and then the mechanical claw moves to the top of the limit column and places the metal rod in the limit groove to limit the shaking of the metal rod, and then the punch of the punching mechanism punches the circumference of the metal rod, after the mechanical claw drives the metal rod through multiple punching mechanisms, the punching operation can be completed at different positions on the circumference of the metal rod, and then the mechanical claw grabs the metal rod and moves the metal rod to the metal rod discharge collection slot, and the above actions are repeated to punch a large number of metal rods.

[0004] However, when the automatic metal rod loading platform pushes the horizontal metal rod to the specified position, the metal rod will inevitably shake and move. When the mechanical claw continuously grasps the metal rod, the grasping positions of the front and rear metal rods are different, which may easily lead to a large number of metal rods with different punching positions after the punching mechanism punches the holes, which will reduce the subsequent assembly accuracy of the baby stroller. Summary of the invention

[0005] In order to improve the problem of different punching positions of a large number of metal rods, the present application provides an automatic punching device for metal rods.

[0010] By adopting the above technical solution, the slide cylinder is started to drive the load-bearing plate to move from the initial position to the working position, and then the telescopic cylinder and the clamping finger cylinder are started. The clamping finger cylinder grasps the metal rod, and the piston rod of the telescopic cylinder is contracted. The clamping finger cylinder drives the metal rod to lift. The slide cylinder is started again to drive the load-bearing plate back to the initial position from the working position. The telescopic cylinder and the clamping finger cylinder are started again. The clamping finger cylinder lowers the grasped metal rod to the limit column in the placement gap and limits it through the limit groove. Then the adjustment cylinder is started, and the piston rod of the adjustment cylinder is used to push the metal rod on the limit column to the specified position. Repeat the above actions, and the metal rod with the adjusted position can be moved to the punching mechanism through the mechanical claw for punching operation. Therefore, the present application discloses an automated punching device for metal rods, which, through a slide cylinder and a carrying plate, drives a plurality of clamping finger cylinders to move back and forth along the length direction of the carrying plate, so that a large number of metal rods can pass through the adjusting mechanism and the punching mechanism in an orderly manner. At the same time, under the push of the two adjusting cylinders, the position of the metal rod moved by the mechanical claw toward the punching mechanism can be corrected, thereby improving the problem of different positions of the metal rod grasped by the mechanical claw when the mechanical claw grasps the metal rod material and moves it to the punching mechanism, thereby improving the problem of different punching positions of a large number of metal rods.

[0012] By adopting the above technical solution, when the adjusting cylinder pushes the metal rod placed in the gap, the angular cylinder is started, and the angular cylinder is used to press against the metal rod placed on the limit column, thereby reducing the risk of the metal rod detaching from the limit column during the process of the adjusting cylinder pushing the metal rod, and improving the stability of the adjusting mechanism in adjusting the position of the metal rod.

On the other hand, during the punching operation, the parts of the punching mechanism are inevitably worn, resulting in errors in the size of the punched holes on the circumference of the metal rod, and new parts need to be replaced before the batch of metal rods are reworked. If only the parts of one of the multiple punching mechanisms are replaced, and the multiple punching mechanisms are used in sequence during rework, not only will the normal size of the punched holes on the circumference of the metal rod be destroyed, but the rework efficiency will also be reduced. Therefore, during rework, if Only one of the multiple punching mechanisms needs to be used for rework. The fixed electromagnet can be powered off first to separate the multiple clamping finger cylinders from the carrier plate, and the multiple clamping finger cylinders can be temporarily stored in the specified position. Then, one of the clamping finger cylinders can be connected to the horizontal moving component, and then the horizontal moving component can be started to move the clamping finger cylinder back and forth between the adjusting cylinder and the punching mechanism used for rework. In this way, not only the electromagnet and the iron plate are used to realize the detachable connection between the clamping finger cylinder and the carrier plate, but also the detachable connection between the horizontal moving component and the clamping finger cylinder is used to improve the rework efficiency of the metal rod with punching holes, and reduce the risk of secondary changes in the size of the punching holes on the circumference of the metal rod during the rework process.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The embodiment of the present application discloses an automatic punching device for metal rods, which aims to improve the problem of different punching positions of a large number of metal rods.

[0044] Example 1

[0045] Reference Figure 1 The automatic punching device for metal rods includes a machine platform 1, a mechanical claw 2, an adjustment mechanism 3 and a plurality of punching mechanisms 4, wherein the top wall of the machine platform 1 is bolted with a fixed bracket 11, a control terminal 5 is bolted on the fixed bracket 11, and the mechanical claw 2 is connected to the fixed bracket 11. The adjustment mechanism 3 and the plurality of punching mechanisms 4 are both installed on the top wall of the machine platform 1 and are all located below the mechanical claw 2. The mechanical claw 2 is used to grab the metal rod material and make the metal rod material pass through the adjustment mechanism 3 and the plurality of punching mechanisms 4 in sequence. The adjustment mechanism 3 is used to adjust the grabbing position of the mechanical claw 2 to grab the metal rod material. The plurality of punching mechanisms 4 are respectively used to punch different positions of the metal rod material.

[0046] Also refer to Figure 2Specifically, the mechanical claw 2 includes a slide cylinder 21 bolted to the fixed bracket 11, a support frame 22 bolted to the slide cylinder 21, a telescopic cylinder 23 bolted to the support frame 22, a bearing plate 24 bolted to the output end of the telescopic cylinder 23, and a plurality of clamping finger cylinders 25 bolted to the surface of the bearing plate 24, wherein the piston rod of the telescopic cylinder 23 is axially perpendicular to the sliding direction of the piston of the slide cylinder 21. The length of the bearing plate 24 is extended along the sliding direction of the piston of the slide cylinder 21, and the adjustment mechanism 3 and the plurality of punching mechanisms 4 are arranged at intervals along the length direction of the bearing plate 24.

[0047] Also refer to Figure 3 , a plurality of clamping finger cylinders 25 are arranged at intervals along the length direction of the carrier plate 24. The clamping finger cylinder 25 has two clamping claws 251 for clamping the metal rod, and the opposite side walls of the two clamping claws 251 are provided with arc grooves 2511, and the groove walls of the arc grooves 2511 are used for the side walls of the metal rod to abut against, thereby reducing the risk of the metal rod being warped due to uneven force when the clamping finger cylinder 25 clamps the metal rod, and at the same time reducing the risk of the metal rod slipping when the clamping finger cylinder 25 is lifted.

[0048] For ease of understanding, the number of clamping finger cylinders 25 is explained here. The adjustment mechanism 3 corresponds to one clamping finger cylinder 25, and the number of multiple punching mechanisms 4 can be two, or two or more. In this application, the number of punching mechanisms 4 is two, and the corresponding two punching mechanisms 4 correspond to two clamping finger cylinders 25. An additional clamping finger cylinder 25 is added to clamp the metal rod of the punching mechanism 4 to the designated material receiving position for collection when the carrier plate 24 moves along its own length direction. In this way, there are four clamping finger cylinders 25 on the carrier plate 24.

[0049] The working process of the mechanical claw 2 is:

[0050] S1: Start the slide cylinder 21, and the support frame 22 drives the bearing plate 24 to move from the initial position to the working position.

[0051] S2: Start the telescopic cylinder 23 and the clamping finger cylinder 25, the clamping finger cylinder 25 grasps the metal rod placed at the specified position, the piston rod of the telescopic cylinder 23 contracts, and the clamping finger cylinder 25 drives the metal rod to lift.

[0052] S3: Start the sliding cylinder to drive the carrying plate 24 back from the working position to the initial position.

[0053] S4: Start the telescopic cylinder 23, the clamping finger cylinder 25, the adjusting mechanism 3 and the punching mechanism 4. The clamping finger cylinder 25 lowers the grasped metal rod to the adjusting mechanism 3. Repeat S1-S3, and the clamping finger cylinder 25 can lower the grasped metal rod to the two punching mechanisms 4 and the designated material receiving position. The adjusting mechanism 3 adjusts the grasping position of the mechanical claw 2 to grasp the metal rod material. The punching mechanism 4 punches the metal rod after the position adjustment. The metal rod after the punching operation falls to the designated material receiving position for collection.

[0054] S5: Repeat S1-S4, and a large number of metal rods pass through the adjustment mechanism 3, the two punching mechanisms 4 and the designated material receiving position in sequence.

[0055] The adjustment mechanism 3 includes an adjustment cylinder 31 slidably connected to the top wall of the machine 1 and an angle cylinder 32 bolted to the top wall of the machine 1. Two adjustment cylinders 31 are provided. The piston rods of the two adjustment cylinders 31 are coaxially arranged. A placement gap 6 is left between the two adjustment cylinders 31. The placement gap 6 is used to accommodate a horizontally placed metal rod. A plurality of limit columns 7 are bolted to the top wall of the machine 1 located in the placement gap 6. The plurality of limit columns 7 are arranged at intervals along the axial direction of the piston rod of the adjustment cylinder 31. A limit groove 71 is provided at the top of the limit column 7. The limit groove 71 is used for placing the metal rod. The end of the piston rod of the adjustment cylinder 31 is abutted against the end of the metal rod in the placement gap 6. The angle cylinder 32 is located between the two adjustment cylinders 31. The angle cylinder 32 is used to press the peripheral wall of the metal rod against the inner wall of the limit groove 71.

[0056] It should be noted that the end of the adjusting cylinder 31 away from its own output end is connected to a shift cylinder 33, and the shift cylinder 33 is used to drive the adjusting cylinder 31 to move axially along its own piston rod. In this way, the adjusting mechanism 3 not only realizes the function of adjusting the position of the metal rod, but also enables the adjusting mechanism 3 to adapt to metal rods of different lengths.

[0057] The working process of the regulating mechanism 3 is:

[0058] The clamping finger cylinder 25 lowers the grasped metal rod to the limiting column 7 in the placement gap 6, and limits the position through the limiting groove 71. The adjusting cylinder 31 and the corner cylinder 32 are started, and the corner cylinder 32 presses the metal rod against the inner wall of the limiting groove 71, and the piston rod of the adjusting cylinder 31 pushes the metal rod on the limiting column 7 to the specified position, so that the position of the mechanical claw 2 to grasp the metal rod can be adjusted.

[0059] Also refer to Figure 4The punching mechanism 4 includes a driving cylinder 41 bolted on the machine 1, a fixing block 42 fixed to the output end of the driving cylinder 41, a fixing finger cylinder 43 bolted to the side wall of the fixing block 42, a punching frame 44 bolted to the top wall of the machine 1, and a punching cylinder 45 with a punching head bolted to the punching frame 44, wherein the piston rod of the driving cylinder 41 is axially perpendicular to the length direction of the bearing plate 24, and the fixing finger cylinder 43 is used to clamp the end of the metal rod. A punching gap 8 is left between the fixing block 42 and the punching frame 44, and the punching gap 8 is used to accommodate the metal rod. The top wall of the machine 1 located in the punching gap 8 is also bolted to multiple limit columns 7, and the punching cylinder 45 is used to punch holes on the circumference of the metal rod.

[0060] It should be noted that the two punching mechanisms 4 punch holes at different positions of the metal rod, which can be understood as the punching cylinders 45 of the two punching mechanisms 4 are respectively located at the two ends of the metal rod that are far away from each other. In this way, the two punching mechanisms can punch holes at both ends of the metal rod. According to actual production needs, the number and position of the punching mechanisms 4 change accordingly with the change of the punching position of the metal rod.

[0061] The working process of the punching mechanism 4 is:

[0062] S1: After the mechanical claw 2 moves the metal rod to the multiple limit columns 7 in the stamping gap 8, the driving cylinder 41 and the fixed finger cylinder 43 are started. The fixed finger cylinder 43 clamps the end of the metal rod, and the driving cylinder 41 moves the metal rod from the initial position to the stamping head position of the stamping cylinder 45.

[0063] S2: The punching cylinder 45 is started, and the punching head performs a punching operation on the peripheral side of the metal rod.

[0064] S3: The driving cylinder 41 and the fixed finger cylinder 43 return the punched metal rod to the initial position, and the fixed finger cylinder 43 releases the metal rod.

[0065] The implementation principle of Example 1 is: through the slide cylinder 21, in combination with the supporting plate 24, multiple clamping finger cylinders 25 are driven to move back and forth along the length direction of the supporting plate 24, so that a large number of metal rods can pass through the adjusting mechanism 3 and multiple punching mechanisms 4 in an orderly manner. At the same time, under the push of the two adjusting cylinders 31, the position of the metal rod moved by the mechanical claw 2 to the punching mechanism 4 can be corrected, thereby improving the problem of different positions of the metal rod grabbed by the mechanical claw 2 when the mechanical claw 2 grabs the metal rod material and moves to the punching mechanism 4, thereby improving the problem of different punching positions of a large number of metal rods.

[0066] Example 2

[0067] Reference Figure 5 and Figure 6The difference between this embodiment and the first embodiment is that the automatic punching device for metal rods further includes a horizontal moving assembly 9 located above the top wall of the machine platform 1, and the horizontal moving assembly 9 is detachably connected to the clamping finger cylinder 25, and the horizontal moving assembly 9 is used to drive the clamping finger cylinder 25 to reciprocate along the length direction of the carrier plate 24. The installation method of the clamping finger cylinder 25 and the carrier plate 24 is changed accordingly, and the rest of the structure is the same as the first embodiment, and will not be repeated.

[0068] An iron plate 252 is fixed to the side wall of the clamping finger cylinder 25, and a protrusion 2521 is integrally formed on the surface of the iron plate 252. A plurality of slots 241 are provided on the surface of the carrier plate 24, and the slots 241 are for the protrusions 2521 to be inserted. The plurality of slots 241 correspond to the plurality of clamping finger cylinders 25, and a fixed electromagnet 242 is fixed to the bottom of the slot 241, and the fixed electromagnet 242 is used to magnetically attract the protrusion 2521. In this way, the fixed electromagnet 242 and the iron plate 252 are used to realize a detachable connection mode between the clamping finger cylinder 25 and the carrier plate 24.

[0069] The horizontal moving assembly 9 includes an XZ-axis moving platform 91 bolted to a fixed bracket 11, a driving servo motor 92 fixed to the couplings of each axis of the XZ-axis moving platform 91, a movable cylinder 93 bolted to the XZ-axis moving platform 91, and an offside electromagnet 94 installed at the output end of the movable cylinder 93, wherein the XZ-axis moving platform 91 has a horizontal moving direction and a vertical moving direction, and the horizontal moving direction is parallel to the length direction of the supporting plate 24.

[0070] The output end of the movable cylinder 93 is fixed with a connecting plate 95, and the offside electromagnet 94 is bolted to the plate surface of the connecting plate 95. The plate surface of the connecting plate 95 is bonded and fixed with a limit bar 951, and the limit bar 951 is abutted against the end of the clamping finger cylinder 25 away from its output end. The movable cylinder 93 drives the offside electromagnet 94 to approach the clamping finger cylinder 25. The side wall of the clamping finger cylinder 25 away from the iron plate 252 is bolted with an adsorption plate 253, and the adsorption plate 253 is magnetically fixed to the offside electromagnet 94.

[0071] The implementation principle of Example 2 is: during the punching operation, the parts of the punching mechanism 4 will inevitably wear out, resulting in errors in the size of the punched holes on the circumference of the metal rod. It is necessary to replace new parts and then rework this batch of metal rods. If only the parts of one of the multiple punching mechanisms 4 are replaced, and the multiple punching mechanisms 4 are passed through in sequence during rework, not only will the normal punched hole size on the circumference of the metal rod be destroyed, but the rework efficiency will also be reduced.

[0072] Therefore, when reworking, if only one of the multiple punching mechanisms 4 is needed for reworking, the fixed electromagnet 242 at the corresponding position of the above-mentioned punching mechanism 4 can be powered off first, and the offside electromagnet 94 can fix the clamping finger cylinder 25 in time through the movable cylinder 93 to achieve the effect of automatically changing the position of the clamping finger cylinder 25. Then start the driving servo motor 92, the XZ axis moving platform 91 first drives the clamping finger cylinder 25 to move downward to the specified position, determines the horizontal moving height of the clamping finger cylinder 25 to avoid the clamping finger cylinder 25 of the carrier plate 24, and then drives the clamping finger cylinder 25 to go back and forth between the adjustment cylinder 31 and the punching mechanism 4 used for reworking, so as to improve the reworking efficiency of the metal rod with punching holes and reduce the risk of secondary changes in the size of the punching holes around the metal rod during the reworking process.

[0073] Example 3

[0074] Reference Figure 7 and Figure 8 The difference between this embodiment and embodiment 2 is that the structure of the horizontal moving component 9 and the structure of the iron plate 252 are changed accordingly, that is, the iron plate 252 has no protrusion 2521, and the remaining structures are the same as those in embodiment 2 and will not be repeated.

[0075] Specifically, the horizontal moving assembly 9 includes a shift servo motor 96 bolted to the side wall of the bearing plate 24, a lead screw 97 coaxially fixed to the rotating shaft of the shift servo motor 96, and a connecting block 98 threadedly connected to the lead screw 97, wherein the lead screw 97 is extended along the length direction of the bearing plate 24. The connecting block 98 is slidably connected to the plate surface of the bearing plate 24.

[0076] The side wall of the connecting block 98 is integrally formed with an abutment plate 99, which is extended along the length direction of the carrier plate 24, and a gap is left between the abutment plate 99 and the lead screw 97. The plate surface of the abutment plate 99 is provided for abutment of the end faces of the plurality of clamping finger cylinders 25 away from their own output ends. The abutment plate 99 is provided for magnetic fixation of the fixed electromagnet 242. The abutment plate 99 is detachably connected to the clamping finger cylinder 25, and the detachable connection method can be magnetic fixation or screw plug fixation, and the embodiment of the present application is not limited thereto.

[0077] The implementation principle of Example 3 is as follows: when the punched metal rod needs to be reworked, the fixed electromagnet 242 is first powered off to separate the multiple clamping finger cylinders 25 from the carrier plate 24, and the multiple clamping finger cylinders 25 are temporarily stored in a designated position, and then one of the clamping finger cylinders 25 is connected to the abutment plate 99, so that the clamping finger cylinder 25 can be moved back and forth between the adjustment cylinder 31 and the punching mechanism 4 used for rework. The horizontal moving assembly 9 of this embodiment is integrated with the mechanical claw 2, so that the horizontal moving assembly 9 can adapt to different installation spaces and metal rods of different sizes.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
