Description

Technical Field

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

[0002] The zipper head 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 head and intermediate connector.

[0003] The zipper pull is the main part of the zipper head, which is used to clamp the chain teeth on both sides so that they can engage or disengage with each other; the zipper pull is usually designed in various flat geometric shapes to facilitate the user to operate the zipper. The zipper pull can be connected directly to the zipper pull body or through an intermediate piece; in some designs, the zipper pull and the zipper pull body are connected through an intermediate connector. This design can increase the flexibility and durability of the zipper. The intermediate connector is often formed by stamping on the zipper pull body.

[0004] ‌Since the intermediate connecting piece required for the connection between the zipper puller and the zipper puller body needs to be stamped, the preset deformation area on the zipper puller body is squeezed to deform it and then wrap the zipper puller, thereby realizing the connection between the zipper puller and the zipper puller body. However, when the existing zipper puller and zipper puller body are combined by stamping, if there is a problem with the transportation of the zipper puller, the zipper puller body will still be stamped, causing the zipper puller body to be scrapped. It is necessary to design a device that can ensure self-detection of the zipper puller and the zipper puller body 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.

[0006] The technical solution adopted by the present invention is: The metal zipper head stamping device is characterized in that it includes a frame, a rotating pressure-bearing system, a pull body conveying system, a slider conveying system, a stamping tube, a stamping force block and two sensing blocks. The rotating pressure-bearing system can be rotatably installed on the frame, and a hooking protrusion is formed on the periphery of the rotating pressure-bearing system. The pull body conveying system forms a pull body conveying groove, and each of the hooking protrusions extends into the pull body conveying groove. A slider resistance device is provided on the side of the pull body conveying groove. The slider conveying system extends to the stamping tube, and a long hole connected to the slider conveying system is opened on the stamping tube. A slider channel is provided in the stamping tube. The stamping force block slides along the end of the slider channel of the stamping tube, and a symmetrical upper guide slope and a lower guide slope are formed at the end of each sensing block away from the slider channel. The upper guide slope is connected to the stamping tube by a dovetail groove sliding pair, and the lower guide slope is connected to the corresponding stamping force block by a dovetail groove sliding pair. A stamping cone groove is provided on the lower side of the stamping force block.

[0007] Preferably, the rotary pressure system includes a rotary pressure plate and a plurality of ejection traction devices, each of which is evenly arranged along the periphery of the rotary pressure plate, each of which is directed radially, each of which slides along the rotary pressure plate, and each of which forms a hooking protrusion.

[0008] Preferably, the pulling body conveying system comprises two conveying rails, and a pulling body conveying groove is formed between the conveying rails.

[0009] Preferably, the slider conveying system comprises a slider conveying pipeline, and the cross-section of the slider conveying pipeline is rectangular.

[0010] Preferably, the stamping tube is slidably mounted on a frame, and the stamping tube is pulled by a cylinder mounted on the frame.

[0011] Preferably, the stamping force-bearing block and the stamping tube slide via a dovetail groove sliding pair.

[0012] 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.

[0013] Preferably, the pull head resistance device is a resistance spring.

[0014] A metal zipper head punching method, using a metal zipper head punching device, comprises the following steps: S1: conveying the zipper puller along the puller conveying groove of the puller conveying system until the zipper puller is stuck on the puller resistance device; S2: The rotary pressure-bearing system rotates, and the hooking protrusions around the rotary pressure-bearing system are embedded in the zipper puller, and the zipper pullers are transported one by one along the puller conveying groove; S3: The zipper puller is conveyed along the puller conveying system until the zipper puller falls into the stamping tube; S4: The stamping tube is pressed downward, and the stamping force block squeezes the deformation rod on the top of the zipper puller, so that the deformation rod wraps the zipper puller preset in the stamping tube. If there is no zipper puller in the stamping tube, the two sensing blocks approach each other, so that the stamping force block avoids the zipper puller.

[0015] The beneficial effects of the present invention are: The rotating pressure-bearing system can be rotatably installed on the frame, and a hooking protrusion is formed on the periphery of the rotating pressure-bearing system. The hooking protrusion is used to insert into the preset hole position on the lower side of the zipper puller, and then transport the zipper puller. The puller conveying system forms a puller conveying groove, and each hooking protrusion extends into the puller conveying groove. A puller resistance device is provided on the side of the puller conveying groove to stop the zipper puller and prevent the influence on the position of the zipper puller during the previous vibration conveying process until the hooking protrusion transports the zipper puller away, driving the zipper puller to overcome the resistance of the puller resistance device, and realizes the sequential transportation of the zipper puller. The puller conveying system extends to the stamping tube, and a long hole connected to the puller conveying system is opened on the stamping tube. A puller channel is provided in the stamping tube, so that the zipper puller transported by the puller conveying system falls into the puller channel from the long hole. The long hole is suitable According to the shape of the zipper puller, the stamping force block slides along the end of the puller channel of the stamping tube, and the end of each sensing block away from the puller channel forms a symmetrical upper guide slope and a lower guide slope, the upper guide slope is connected to the stamping tube through a dovetail groove sliding pair, and the lower guide slope is connected to the corresponding stamping force block through a dovetail groove sliding pair. A stamping cone groove is provided on the lower side of the stamping force block. When a zipper puller falls, the stamping tube is pressed down, and the sensing block will be pressed on the zipper puller, and then when the stamping tube is pressed down, the force of the stamping force block is guaranteed, so that the stamping cone groove squeezes the zipper puller body and then wraps the zipper puller. When the zipper puller does not fall due to transportation problems, after the stamping tube is pressed down, each sensing block is close to each other because there is no support from the zipper puller, and the stamping force block is not stressed, thereby ensuring production efficiency and avoiding waste.

[0024] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 7As shown, the present embodiment provides a metal zipper head stamping device, including a frame 5, a rotary pressure-bearing system 1, a zipper body conveying system 2, a zipper 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 a preset hole on the lower side of the zipper body 6 to convey the zipper body 6. The zipper body conveying system 2 forms a zipper body conveying groove 21, and each hooking protrusion extends into the zipper 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 previous vibration conveying process until the hooking 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, so as to realize the sequential conveying of the zipper pull body 6. The pull head conveying system 3 extends to the punching tube 41, and a long hole 411 connected to the pull head conveying system 3 is opened on the punching tube 41. A pull head channel 412 is provided in the punching tube 41, so that the pull head conveying system 3 conveys The incoming zipper pull head 7 falls into the pull head channel 412 from the long hole 411, and 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 Conical groove 421, when the zipper puller 7 falls, when the stamping tube 41 is pressed down, the sensing block 43 will press on the zipper puller 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 puller 6 and then wraps the zipper puller 7. When the zipper puller 7 does not fall due to transportation problems, after the stamping tube 41 is pressed down, the sensing blocks 43 are not supported by the zipper puller 7, so that the two sensing blocks 43 are close to each other, and the stamping force block 42 is not stressed, thereby ensuring production efficiency and avoiding waste.

[0025] 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, each ejection traction device 12 is directed radially, each ejection traction device 12 slides along the rotary pressure plate 11, each ejection traction device 12 forms a hooking protrusion, and 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, and the rotary pressure plate 11 is driven to rotate by the reduction motor 13, and 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 then 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.

[0026] 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 puller 6 , that is, the zipper puller 6 slides in the zipper conveying groove 21 .

[0027] Specifically, the slider conveying system 3 includes a slider conveying pipeline, the cross section of which is rectangular, so as to facilitate the movement of the zipper slider 7 . The zipper slider 7 slides from the slider conveying pipeline until it falls from the long hole 411 .

[0028] 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.

[0029] Specifically, the stamping force bearing block 42 and the stamping tube 41 slide through a dovetail groove sliding pair to ensure reliable sliding.

[0030] 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, which facilitates the passage of the zipper slider 7.

[0031] Specifically, the slider resistance device 22 is a resistance spring sheet. When the ejection pulling device 12 pulls the zipper puller 6, the zipper puller 6 overcomes the resistance of the resistance spring sheet and moves one by one.

[0032] A metal zipper head punching method, using a metal zipper head punching device, comprises the following steps: S1: conveying the zipper puller 6 along the puller conveying groove 21 of the puller conveying system 2 until the zipper puller 6 is stuck on the slider resistance device 22; S2: the rotary pressure-bearing system 1 rotates, and the hooking protrusions around the rotary pressure-bearing system 1 are embedded in the zipper puller 6, and the zipper pullers 6 are transported one by one along the puller conveying groove 21; S3: the zipper puller 7 is transported along the puller conveying system 3 until the zipper puller 7 falls into the stamping tube 41; S4: the stamping tube 41 is pressed downward, and the stamping 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 stamping tube 41. If there is no zipper puller 7 in the stamping tube 41, the two sensing blocks 43 are close to each other, so that the stamping force block 42 avoids the zipper puller 6. When the zipper puller 6 does not have a corresponding zipper puller 7 falling, the zipper puller 6 is prevented from being damaged by stamping.
