Description

Technical Field

[0001] The present invention relates to the technical field of zipper head stamping, in particular to a metal zipper head stamping device and a stamping method thereof. Background Art

[0002] The zipper pull is one of the core components of the zipper, responsible for engaging or disengaging the chain teeth. It mainly consists of the zipper body, zipper pull and intermediate connector.

[0003] The zipper pull is the main part of the zipper head, used to clamp the zipper teeth on both sides, allowing them to engage and disengage with each other. Zipper pulls are usually designed with various flat geometric shapes to facilitate user operation of the zipper. The zipper pull can be connected directly to the zipper body or through an intermediate component. In some designs, the zipper pull and zipper body are connected by an intermediate connector. This design can increase the flexibility and durability of the zipper. The intermediate connector is often stamped into the zipper body.

[0004] ‌Since the intermediate connecting piece required for the connection between the zipper pull and the zipper pull body needs to be stamped, the preset deformation area on the zipper pull body is squeezed to deform it and then wrap the zipper pull, thereby realizing the connection between the zipper pull and the zipper pull body. However, when the existing zipper pull and zipper pull body are stamped together, if there is a problem with the zipper pull conveying, the zipper pull body will still be stamped, causing the zipper pull body to be scrapped. It is necessary to design a device that can ensure that the zipper pull and zipper pull body are self-detected and delivered into place before stamping, so as to ensure production efficiency and avoid waste. Summary of the Invention

[0005] In order to overcome the technical defects of the prior art, the present invention provides a metal zipper head punching device and a punching method thereof, which ensure production efficiency and avoid waste.

[0013] Preferably, when the stamping force block drops to the lower limit position, the distance between the two sensing blocks is greater than the width of the slider channel.

[0014] Preferably, the slider resistance device is a resistance spring.

[0015] A metal zipper head stamping method using a metal zipper head stamping device includes the following steps:

[0016] S1: conveying the zipper pull along the pull conveying trough of the pull conveying system until the zipper pull is stuck on the slider resistance device;

[0017] S2: The rotary pressure-bearing system rotates, and the hook protrusions around the rotary pressure-bearing system are embedded in the zipper pull body, and the zipper pull bodies are transported one by one along the pull body conveying groove;

[0018] S3: The zipper pull is transported along the pull conveying system until the zipper pull falls into the stamping tube;

[0019] S4: The stamping tube is pressed down, and the stamping force block squeezes the deformation rod on the top of the zipper pull body, so that the deformation rod wraps the zipper pull head preset in the stamping tube. If there is no zipper pull head in the stamping tube, the two sensing blocks approach each other, causing the stamping force block to avoid the zipper pull body.

[0020] The beneficial effects of the present invention are:

[0038] The present invention will be further described below in conjunction with the accompanying drawings:

[0039] like Figure 1 — Figure 7As shown, this embodiment provides a metal zipper head stamping device, including a frame 5, a rotary pressure-bearing system 1, a pull body conveying system 2, a pull head conveying system 3, a stamping tube 41, a stamping force block 42 and two sensing blocks 43. The rotary pressure-bearing system 1 can be rotatably installed on the frame 5. The periphery of the rotary pressure-bearing system 1 forms a hooking protrusion, which is used to insert into the preset hole position on the lower side of the zipper pull body 6, and then convey the zipper pull body 6. The pull body conveying system 2 forms a pull body conveying groove 21, and each hooking protrusion extends into the pull body conveying groove 21. A pull head resistance device 22 is provided on the side of the body conveying groove 21 to stop the zipper pull body 6 and prevent the influence on the position of the zipper pull body 6 during the front vibration conveying process until the hook protrusion drives the zipper pull body 6 to overcome the resistance of the pull head resistance device 22 and convey the zipper pull body 6 away, thereby realizing the sequential conveying of the zipper pull body 6. The pull head conveying system 3 extends to the punching tube 41. The punching tube 41 is provided with a long hole 411 connected to the pull head conveying system 3. The punching tube 41 is provided with a pull head channel 412, so that the pull head conveying system 3 can convey The incoming zipper pull head 7 falls into the pull head channel 412 from the long hole 411. The long hole 411 is adapted to the shape of the zipper pull head 7. The stamping force block 42 slides along the end of the pull head channel 412 of the stamping tube 41. The end of each sensing block 43 away from the pull head channel 412 forms a symmetrical upper guide slope 431 and a lower guide slope 432. The upper guide slope 431 is connected to the stamping tube 41 through a dovetail groove sliding pair, and the lower guide slope 432 is connected to the corresponding stamping force block 42 through a dovetail groove sliding pair. The lower side of the stamping force block 42 is provided with a stamping The conical groove 421, when the zipper pull head 7 falls, when the stamping tube 41 is pressed down, the sensing block 43 will press on the zipper pull head 7, and then when the stamping tube 41 is pressed down, the force of the stamping force block 42 is guaranteed, so that the stamping conical groove 421 squeezes the zipper pull body 6 and then wraps the zipper pull head 7. When the zipper pull head 7 does not fall due to transportation problems, after the stamping tube 41 is pressed down, the sensing blocks 43 are close to each other because there is no support from the zipper pull head 7, and the stamping force block 42 is not subjected to force, thereby ensuring production efficiency and avoiding waste.

[0040] Specifically, the rotary pressure system 1 includes a rotary pressure plate 11 and a plurality of ejection traction devices 12. Each ejection traction device 12 is evenly arranged along the periphery of the rotary pressure plate 11. The direction of each ejection traction device 12 is radial. Each ejection traction device 12 slides along the rotary pressure plate 11. Each ejection traction device 12 forms a hooking protrusion. When the ejection traction device 12 contacts the zipper puller 6, it pulls the zipper puller 6 to move along the puller conveying groove 21. The rotary pressure plate 11 is driven to rotate by the reduction motor 13. The reduction motor 13 is installed on the frame 5. After the stamping tube 41 is pressed down, the stamping tube 41 presses down the stamping force block 42, and presses the zipper puller 6 onto the rotary pressure plate 11, so that the rotary pressure plate 11 overcomes the downward pressure on the zipper puller 6.

[0041] Specifically, the zipper conveying system 2 includes two conveying rails 23 , and a zipper conveying groove 21 is formed between the conveying rails 23 to facilitate the movement of the zipper pull 6 . That is, the zipper pull 6 slides in the zipper conveying groove 21 .

[0042] Specifically, the slider conveying system 3 includes a slider conveying pipe, the cross section of which is rectangular, so as to facilitate the movement of the zipper slider 7 . The zipper slider 7 slides along the slider conveying pipe until it falls from the long hole 411 .

[0043] Specifically, the punching tube 41 is slidably mounted on the top of the frame 5 , and the punching tube 41 is pulled by the cylinder 8 mounted on the frame 5 to achieve downward pressing and punching.

[0044] Specifically, the stamping force bearing block 42 and the stamping tube 41 slide via a dovetail groove sliding pair to ensure reliable sliding.

[0045] Specifically, when the stamping force block 42 drops to the lower limit position, the distance between the two sensing blocks 43 is greater than the width of the slider channel 412, making it easier for the zipper slider 7 to pass through.

[0046] Specifically, the slider resistance device 22 is a resistance spring. When the ejection pulling device 12 pulls the zipper slider 6, the zipper sliders 6 overcome the resistance of the resistance spring and move one by one.

[0047] A metal zipper head stamping method using a metal zipper head stamping device includes the following steps:

[0048] S1: conveying the zipper pull 6 along the pull conveying groove 21 of the pull conveying system 2 until the zipper pull 6 is stuck on the slider resistance device 22;

[0049] S2: The rotary pressure-bearing system 1 rotates, and the hooking protrusions on the periphery of the rotary pressure-bearing system 1 engage with the zipper puller 6, and the zipper pullers 6 are conveyed one by one along the puller conveying groove 21;

[0050] S3: The zipper pull 7 is transported along the pull conveying system 3 until the zipper pull 7 falls into the stamping tube 41;

[0051] S4: The punching tube 41 is pressed downward, and the punching force block 42 squeezes the deformation rod 61 on the top of the zipper puller 6, so that the deformation rod 61 wraps the preset zipper puller 7 in the punching tube 41. If there is no zipper puller 7 in the punching tube 41, the two sensing blocks 43 approach each other, so that the punching force block 42 avoids the zipper puller 6, and when the zipper puller 6 falls without the corresponding zipper puller 7, the zipper puller 6 is prevented from being damaged by punching.
