Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment for forming metal parts, in particular to a stamping and forming device for clothing buttons. Background Art

[0002] Buttons are a common clothing accessory, usually used to fasten and decorate clothing. They are usually made of metal, plastic, wood, ceramics and other materials, with various shapes such as round, square, oval, etc. Buttons generally consist of two parts: the button body and the buttonhole or buckle. The button cooperates with the corresponding part on the clothing through the buttonhole or buckle to fix the clothing. In addition to its practical function, buttons are also often used to add beauty to clothing and become a part of the design.

[0003] After searching, it was found that the prior art announcement number is CN 214639438 U, which discloses a clothing button stamping and forming device for button stamping and forming, including a support plate and a lower pressing plate moving toward the support plate, a punching head for stamping and forming is fixedly installed on the lower surface of the lower pressing plate, and a punching column for driving it to press downward is fixedly installed on the upper surface of the lower pressing plate, and a stamping die for placing workpieces is provided on the upper part of the support plate, and the stamping column drives the lower pressing plate to move downward so that the punching head completes the stamping and forming. This scheme drives multiple stamping dies to rotate by setting a turntable, and stamping is performed on the stamping dies in turn. In this way, when the staff loads and unloads the workpieces on the stamping die, their hands are located in front of the stamping head, which avoids the occurrence of production accidents and increases the safety of the entire device when in use. At the same time, the structure of the entire device is simple and reasonable, and the rotation of the stamping die does not require extra operations to complete.

[0004] Therefore, based on the above search and in combination with the existing technology, during the use of the above scheme, the buttons are not effectively clamped during the stamping process, and they may slip or rotate in the mold, resulting in inaccurate stamping position, thereby causing size deviation or irregular shape. At the same time, when workers are placing buttons, since the buttons are small, they may stick to the skin or be hooked by the filaments of the gloves after placement, resulting in the need to repeatedly position them, thereby extending the production cycle. For this reason, we propose a clothing button stamping forming device. Summary of the invention

[0005] The object of the present invention is to provide a clothing button stamping and forming device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clothing button stamping and forming device, comprising a base, a support column is fixedly installed on the upper end of the base, a support rod is fixedly installed on the upper end of the base, a high-pressure pump is fixedly installed on the right end of the support rod, and a punch for stamping and forming buttons is fixedly installed on the output end of the high-pressure pump, a tray is arranged above the support column, a spherical groove is arranged at the center of the tray, a punching hole is opened at the center of the tray, a mold seat for placing buttons is arranged in the punching hole, and a sliding cylinder is fixedly installed at the bottom end of the tray, the sliding cylinder is sleeved on the outer surface of the support column, a movable sleeve is fixedly installed on the inner end of the sliding cylinder, and a stabilizing device capable of straightening the punched buttons is arranged inside the movable sleeve, and a center column is passed through the center of the tray.

[0007] As a further solution of the present invention, the stabilizing device includes a plurality of balancing rods, which are ring-shaped and rotatably mounted on the inner bottom end of the tray. A plurality of extension holes are provided at the upper end of the tray, and one end of the balancing rod away from the tray passes through the extension hole and is exposed above the tray. The balancing rods rotate in a direction approaching each other to clamp the outer surface of the button to be processed, thereby effectively stabilizing the position of the button to prevent it from slipping or shifting during the stamping process, thereby ensuring stamping accuracy and product quality.

[0008] As a further solution of the present invention, a passive ring is slidably installed on the outer surface of the central column, and a plurality of traction rods are rotatably installed on the outer surface of the passive ring, and the traction rods are rotatably connected to the corresponding balance rods respectively. When the passive ring moves downward, the balance rods are pulled to rotate by the traction rods, thereby achieving uniformity of force, so that the buttons can be clamped more evenly.

[0009] As a further solution of the present invention, negative pressure cylinders are fixedly installed on both ends of the inner side of the movable sleeve, a rectangular hole is opened on the outer surface of the negative pressure cylinder, a sliding rod is slidably installed in the rectangular hole, an output rod is rotatably installed on one end of the sliding rod close to the center column, and the end of the output rod away from the sliding rod is rotatably connected to the outer surface of the center column.

[0010] As a further solution of the present invention, support blocks are fixedly installed on both sides of the upper end of the support column, and the ends of the support blocks close to each other are fixedly connected with stabilizing sleeves, and the stabilizing sleeve is inserted into the interior of the negative pressure cylinder, and a movable plug is slidably installed on the inner end of the negative pressure cylinder, and a negative pressure chamber is formed between the upper end of the movable plug and the negative pressure cylinder. Under the action of atmospheric pressure, the movable plug maintains an upward force, and under the action of atmospheric pressure, the force of the movable plug moving upward becomes greater. As the movable plug moves upward, the clamping part of the stabilizing sleeve will clamp the button more tightly, effectively preventing the button from slipping or shifting in position during the stamping process, ensuring the accuracy of the stamping, and at the same time enabling the button to be clamped more tightly, reducing the complexity of manual operation, and avoiding uneven or unstable clamping force caused by human factors.

[0011] As a further solution of the present invention, a locking ring capable of locking the active plug in the current position is fixedly installed on the upper end of the stabilizing sleeve, and a passive fork is fixedly connected to one end of the sliding rod close to the stabilizing sleeve. The passive fork sleeve is arranged on the outer surface of the stabilizing sleeve, and lifting blocks capable of releasing the locking state of the active plug are fixedly installed on the front and rear sides of the upper end of the passive fork.

[0012] As a further solution of the present invention, a movable groove is provided at the bottom end of the movable plug, a synchronous ring is slidably installed at the inner end of the movable groove, and latches are fixedly connected to the left and right sides of the bottom end of the synchronous ring.

[0013] As a further solution of the present invention, two lock holes are opened on the outer surface of the locking ring, and the two lock holes correspond to the lock latch. After the movable plug moves downward, the lock latch is inserted into the lock hole, and the movable plug is fixedly connected to the passive ring by a traction line.

[0014] As a further solution of the present invention, a high-pressure cylinder is fixedly installed on the upper end of the support column, a compression plug is slidably installed on the inner end of the high-pressure cylinder, and a support sleeve is fixedly installed on the upper end of the compression plug, the upper end of the support sleeve and the bottom end of the movable sleeve are in contact with each other, and a plurality of pressure relief cylinders are fixedly installed on the upper end of the support column, and the pressure relief cylinders and the high-pressure cylinders are respectively connected by high-pressure pipes. By dispersing the force of the punch, the service life of the device is extended.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the present invention is used, the button can be lifted up by moving the center column upward, so that the formed button can be quickly taken out of the mold to avoid the button being stuck in the mold, thereby avoiding the downtime required for manual intervention or equipment adjustment due to the stuck, making the production process smoother and improving the production efficiency;

[0017] 2. When the present invention is used, the button is lifted by the central column, so that the space in the mold can be better utilized to avoid material accumulation or jamming, thereby maximizing the space utilization efficiency of the equipment and production line and meeting the needs of mass production;

[0018] 3. The present invention can avoid inconsistent shapes of buttons due to slippage or unstable positioning during the stamping process, reduce molding defects caused by misalignment, such as extra protrusions, misplaced holes or uneven edges, thereby reducing manual intervention, ensuring consistency and accuracy in each production cycle, and reducing errors caused by manual operation;

[0019] 4. When the present invention is used, the hydraulic oil inside the high-pressure cylinder compresses the air inside the pressure relief cylinder to obtain a reaction force, which can ensure that the force is applied more evenly during the stamping process, thereby enabling the pressure during the stamping process to be better controlled, reducing vibration and impact in the mechanical system, avoiding instability caused by vibration, and making the force borne by each component more evenly distributed, thereby reducing excessive wear and damage to certain components and extending the service life of the equipment.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 to Figure 3 A device for stamping and forming buttons for clothing comprises a base 1, a support column 6 is fixedly installed on the upper end of the base 1, a support rod 5 is fixedly installed on the upper end of the base 1 by bolts, a high-pressure pump 4 is fixedly installed on the right end of the support rod 5, and the high-pressure pump 4 can instantly provide impact force. It is an existing mature technology and will not be described in detail here. A punch 3 for stamping and forming buttons is fixedly installed on the output end of the high-pressure pump 4 by bolts, and a tray 2 is arranged above the support column 6. A spherical groove is arranged at the center of the tray 2, so that workers can more accurately slide the button to the center of the tray 2 through the spherical groove, and can quickly determine the center point directly by the touch of the fingers;

[0035] A punching hole is provided at the center of the tray 2, and a mold seat 102 for placing buttons is provided in the punching hole, and a sliding cylinder 101 is fixedly installed at the bottom end of the tray 2, and the sliding cylinder 101 is sleeved on the outer surface of the support column 6, and a movable sleeve 103 is fixedly installed at the inner end of the sliding cylinder 101, and a stabilizing device capable of straightening the button to be punched is provided inside the movable sleeve 103. Specifically, the stabilizing device can clamp the button after it is placed on the mold seat 102 and further make the button in the center position, thereby reducing the defective rate of the button in the final molding, and a center column 11 is penetrated at the center of the tray 2;

[0036] See also Figure 3 , Figure 4 , Figure 5 The stabilizing device includes a plurality of balancing rods 104. The ends of the balancing rods 104 that are close to each other are fixedly installed with anti-skid rubber pads to increase the friction between the buttons. The balancing rods 104 are annular and rotatably installed on the inner bottom end of the tray 2. The upper end of the tray 2 is provided with a plurality of extension holes, and the ends of the balancing rods 104 that are away from the tray 2 are exposed above the tray 2 after passing through the extension holes. Specifically, the balancing rods 104 rotate in a direction of approaching each other to clamp the outer surface of the button to be processed, thereby preventing the button from slipping during the impact of the punch 3.

[0037] A passive ring 106 is slidably mounted on the outer surface of the center column 11. Specifically, a rectangular block is fixedly mounted on the inner end of the passive ring 106. A sliding groove is provided on the outer surface of the center column 11. The rectangular block is located in the sliding groove, so that the passive ring 106 can rotate when it moves up and down. A plurality of traction rods 105 are rotatably mounted on the outer surface of the passive ring 106, and the traction rods 105 are rotatably connected to the corresponding balance rods 104, respectively. The connection position is close to the center of the balance rod 104, so that the pulling process is more labor-saving. When the passive ring 106 moves downward, the balance rod 104 is pulled to rotate by the traction rod 105.

[0038] Two limit rings are fixedly installed on the outer surface of the central column 11 . The two limit rings are respectively located on the upper and lower sides of the passive ring 106 , so that the passive ring 106 can only move between the two limit rings. The passive ring 106 is connected to the lower limit ring through a reset spring 107 .

[0039] Example 2: Please refer to Figure 4 , Figure 5 , Figure 6 , a button stamping and forming device for clothing, based on the embodiment 1, negative pressure cylinders 301 are fixedly installed at both ends of the inner side of the movable sleeve 103, and a rectangular hole is opened on the outer surface of the negative pressure cylinder 301, and a sliding rod 302 is slidably installed in the rectangular hole, and the sliding rod 302 is connected to the negative pressure cylinder 301 by a spring sheet, and the end of the sliding rod 302 close to the central column 11 is rotatably installed with an output rod 109, and the end of the output rod 109 away from the sliding rod 302 is rotatably connected to the outer surface of the central column 11, and the output rod 109 is arranged in an inclined manner to prevent the central column 11 from being unable to move up and down normally. Specifically, the upper end of the central column 11 extends a distance above the tray 2, so when the worker places the button on the upper side of the tray 2 and presses the central column 11 downward, the central column 11 then pushes the sliding rods 302 on the left and right sides in the direction away from each other through the output rod 109;

[0040] Support blocks 407 are fixedly installed on both sides of the upper end of the support column 6, and the ends of the support blocks 407 close to each other are fixedly connected with stabilizing sleeves 303 by bolts, and the stabilizing sleeve 303 is inserted into the interior of the negative pressure cylinder 301, and a movable plug 306 is slidably installed on the inner end of the negative pressure cylinder 301. A sealing rubber ring is fixedly installed on the outer surface of the movable plug 306, and it fits tightly with the inner wall of the negative pressure cylinder 301 to increase air tightness. A negative pressure chamber is formed between the upper end of the movable plug 306 and the negative pressure cylinder 301, and the movable plug 306 maintains an upward force under the action of atmospheric pressure;

[0041] like Figure 6 As shown, a locking ring 305 capable of locking the movable plug 306 in the current position is fixedly installed on the upper end of the stabilizing sleeve 303, and a passive fork 304 is fixedly connected to one end of the sliding rod 302 close to the stabilizing sleeve 303. The passive fork 304 is sleeved on the outer surface of the stabilizing sleeve 303, and lifting blocks 313 capable of releasing the locking state of the movable plug 306 are fixedly installed on the front and rear sides of the upper end of the passive fork 304. Specifically, a movable groove 307 is provided at the bottom end of the movable plug 306, and a synchronous ring 315 is slidably installed at the inner end of the movable groove 307. A limiting plate is fixedly installed at the bottom end of the movable plug 306, and the synchronous ring 315 is located above the limiting plate, thereby preventing the synchronous ring 315 from detaching from the movable plug 306. A stabilizing rod 308 is fixedly installed at the bottom end of the movable plug 306. The stabilizing rod 308 is fixedly installed at the bottom end of the movable plug 306. 08 is passed through the interior of the stabilizing sleeve 303, so that the movable plug 306 is more stable when moving, and the left and right sides of the bottom end of the synchronizing ring 315 are fixedly connected with latches 310, and the outer surface of the locking ring 305 is provided with two locking holes 316, and the two locking holes 316 correspond to the latches 310. The synchronizing ring 315 and the movable plug 306 are connected by an unlocking spring 309, so that after the synchronizing ring 315 is forced to move, it can be restored to its initial state by the elastic force of the unlocking spring 309, and after the movable plug 306 moves downward, the latch 310 is passed through the lock hole 316, and the movable plug 306 is fixedly connected to the passive ring 106 by the traction line 108, and then, under the elastic force of the unlocking spring 309, the latch 310 can be firmly hooked under the locking ring 305;

[0042] The outer surface of the stabilizing sleeve 303 is provided with an unlocking ring 312, and the upper end of the unlocking ring 312 is fixedly installed with an unlocking block 311, which is triangular in shape, and after the unlocking block 311 moves upward, it can be squeezed by the slope to make the latch 310 detach from the locking ring 305. Specifically, a rectangular slider is fixedly installed at the inner end of the unlocking ring 312, and a rectangular slide groove is provided on the outer surface of the stabilizing sleeve 303. The rectangular slide groove is located in the rectangular slide groove, so that the unlocking ring 312 will not rotate when it moves up and down, and the outer surface of the unlocking ring 312 is provided with two clamping holes 314, and the two clamping holes 314 are respectively penetrated into two lifting blocks 313. More specifically, the right end of the lifting block 313 is inclined, and the inclined surface and the clamping hole 314 are staggered with each other, so that when the passive fork 304 moves toward the right side, the unlocking ring 312 can move upward under the squeezing of the inclined surface;

[0043] See also Figure 7 , Figure 8 , Fig. 9 A high-pressure cylinder 401 is fixedly installed on the upper end of the support column 6, a compression plug 405 is slidably installed on the inner end of the high-pressure cylinder 401, and a support sleeve 402 is fixedly installed on the upper end of the compression plug 405, and the upper end of the support sleeve 402 is in contact with the bottom end of the movable sleeve 103. Specifically, a sealing ring is fixedly installed on the outer surface of the compression plug 405, and the sealing ring is tightly fitted with the inner wall of the high-pressure cylinder 401. A plurality of pressure relief cylinders 404 are fixedly installed on the upper end of the support column 6, and the pressure relief cylinders 404 and the high-pressure cylinder 401 are respectively connected through high-pressure pipes 403. Specifically, the interior of the high-pressure cylinder 401 is filled with hydraulic oil. When the support sleeve 402 moves downward under pressure, the internal hydraulic oil can be transmitted to the pressure relief cylinder 404 through the high-pressure pipe 403;

[0044] A synchronization plug 406 is slidably installed at the inner end of the pressure relief cylinder 404. The left side of the synchronization plug 406 is air, and the right side is filled with hydraulic oil. When the hydraulic oil enters the pressure relief cylinder 404, it pushes the synchronization plug 406 to move to the left and compresses the air in the left chamber of the synchronization plug 406. When the hydraulic oil no longer pushes the synchronization plug 406, the compressed air begins to release, and pushes the hydraulic oil back into the high-pressure cylinder 401.

[0045] The working principle of the present invention is:

[0046] When in use, the button to be processed is placed in the tray 2, and the button can be quickly positioned above the mold seat 102 through the ball groove inside the tray 2, and slightly pressed downward to force the center column 11 to move downward. At this time, the center column 11 moves downward and drives the left and right sliding rods 302 to move away from each other through the output rod 109, and the movement of the sliding rod 302 drives the passive fork 304 to move horizontally, thereby realizing that the lifting block 313 pushes the unlocking ring 312 upward;

[0047] Then, during the upward movement of the unlocking ring 312, the locking block 311 releases the latch 310 from the locking ring 305. At this time, since the cavity above the active plug 306 is at negative pressure, the active plug 306 starts to move upward under the action of atmospheric pressure, and pulls the passive ring 106 downward through the traction line 108. During the downward movement of the passive ring 106, the traction rod 105 is pulled, thereby driving the balance rod 104 to move in a direction close to each other, thereby clamping the button to prevent the button from slipping during the stamping process.

[0048] Then, the punch 3 moves downward rapidly under the push of the high-pressure pump 4 and hits the button. Then, under the strong punching force, the sliding cylinder 101 starts to move downward as a whole, so that the compression plug 405 moves downward, and the hydraulic oil inside the high-pressure cylinder 401 flows into the pressure relief cylinder 404 through the high-pressure pipe 403, so that the air on the left side of the synchronization plug 406 inside the pressure relief cylinder 404 is compressed, and multiple pressure relief cylinders 404 can decompose the punching force;

[0049] At the same time, as the sliding cylinder 101 moves downward, the locking ring 305 begins to approach the movable plug 306, and then the latch 310 passes through the lock hole 316 again. When the punch 3 is punched, the air inside the pressure relief cylinder 404 is released, and the hydraulic oil is pushed back to the high-pressure cylinder 401 through the synchronization plug 406, so that the compression plug 405 moves upward and pushes the movable sleeve 103 upward through the support sleeve 402. At this time, the movable plug 306 can be restored to its initial state, and the top of the movable plug 306 returns to the negative pressure state, and the passive ring 106 moves upward under the elastic force of the reset spring 107, driving the balance rod 104 to no longer clamp the button, and then the center column 11 moves upward under the action of the spring, pushing the button embedded in the mold base 102 upward to facilitate the worker to take it.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
