Description

Technical Field

[0001] This invention relates to the field of wire cutting equipment technology, specifically to a wire cutting device for zipper U-shaped codes. Background Technology

[0002] In the zipper manufacturing industry, U-shaped clips (also known as U-shaped metal clips or U-shaped wire clips) are an indispensable key component of zipper heads. They are usually made from metal wire with a certain cross-sectional shape through processes such as bending and cutting. Currently, traditional U-shaped clip wire cutting equipment has the following obvious defects and shortcomings in actual use: First, the wire is prone to secondary bending during multiple transfers and repositioning processes, resulting in poor dimensional consistency of the final U-shaped code. Secondly, most existing punching equipment operates in an intermittent mode, that is, feeding the line, stopping, punching, and feeding the line again. This "one step, one stop" working method not only limits the production speed, but also easily affects the accuracy of the punching position due to the inertial fluctuations caused by the start and stop of the line feeding. Third, existing equipment lacks a dedicated straightening and pre-forming mechanism for the special cross-sectional shape of U-shaped code wire; To address the aforementioned issues, a wire punching device for zipper U-shaped codes is proposed.

[0017] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 10The present invention preferably provides the following technical solution: a wire punching device for zipper U-shaped codes, comprising: a frame; a wire feeding assembly disposed on the frame for continuously feeding U-shaped code wire; a straightening and forming mechanism disposed on the frame and located on the discharge side of the wire feeding assembly, the straightening and forming mechanism comprising at least one set of straightening components 04 and a pre-forming and flattening component, the straightening components 04 being used to adapt to the cross-sectional shape of the U-shaped code wire and straighten the wire in multiple dimensions, the pre-forming and flattening component being used to pre-sort and flatten the straightened wire before cutting, so as to output pre-formed wire with a flat cross-section and straightness meeting the standard; and a cutting and punching mechanism disposed on the frame and located on the discharge side of the straightening and forming mechanism, the cutting and punching mechanism comprising a moving blade assembly and a driving component, the moving blade assembly reciprocating under the drive of the driving component, for punching and forming the pre-formed wire without stopping the wire, so that the U-shaped code is separated under continuous wire feeding.

[0019] like Figure 1 , 2 As shown in Figure 5, the present invention integrates the continuous conveying, multi-dimensional straightening, pre-forming and flattening and non-stop punching of U-shaped wire into an integrated forming device by sequentially arranging the wire feeding assembly, straightening and forming mechanism and cutting and punching mechanism along the frame, which greatly improves the continuity of production and the product qualification rate. The U-shaped code wire mentioned in this article refers to metal wire with a specific cross-sectional shape used to make zipper U-shaped codes.

[0020] Among them, the straightening component 04, where the straightening and forming mechanism is located, is specially designed to adapt to the cross-sectional shape of the U-shaped code wire, and can straighten the wire from multiple dimensions; together with the pre-forming and flattening component, the wire is pre-sorted and flattened before cutting, ensuring that the output pre-formed wire with a flat cross-section and straightness meets the standards, providing a reliable blank base for subsequent high-precision punching, and making the formed U-shaped code dimension stable and consistent.

[0021] The cutting and punching mechanism is designed with a moving blade assembly and a drive unit to drive the moving blade assembly to reciprocate, which enables non-stop punching and forming. The U-shaped code can be separated from the wire in the continuous wire feeding state without stopping the machine, which significantly improves production efficiency and meets the needs of mass and automated production of zipper U-shaped codes.

[0022] Therefore, this invention, through its integrated molding and continuous production design, not only simplifies the operation process and reduces labor costs, but also reduces energy waste by having all mechanisms work together, resulting in significant practicality and economic benefits. It solves the technical problems of dispersed processes and low efficiency in existing zipper U-code processing.

[0023] Furthermore, the frame includes a base 01, a first side plate 011 and a bracket 012 sequentially fixed to the base 01 along the U-shaped wire conveying direction, as shown below. Figure 1, 2 As shown in Figure 3, the overall structure of the frame is reasonable, compact and stable, providing a precise assembly reference for the wire feeding assembly, straightening and forming mechanism and cutting and punching mechanism.

[0024] Example 2 In another embodiment of the present invention, the wire feeding assembly includes: a second side plate 02, disposed on the side wall of the base 01 and distributed opposite to the first side plate 011; two bearing sleeves 021, respectively built into through holes opened on the second side plate 02 and the first side plate 011 and laterally connected to a drive shaft 022; and a winding roller 023, fixed in the middle of the drive shaft 022 and used for winding and unwinding U-shaped wire; and also includes a belt drive assembly for driving the drive shaft 022 to rotate.

[0025] Furthermore, the belt drive assembly includes a first drive wheel 024 fixed to one end of the drive shaft 022, an assembly base fixed to the first side plate 011, and a drive motor 025 mounted on the assembly base. The drive motor 025 is equipped with a second drive wheel 026 through a coupling at its output end, and a drive belt 027 is sleeved between the second drive wheel 026 and the first drive wheel 024.

[0026] like Figure 1 , 2 As shown in Figures 3 and 6, the winding roller 023 is fixed on the drive shaft 022 and wound with wire. When the drive motor 025 on the belt drive assembly drives the second drive wheel 026, the drive belt 027 and the first drive wheel 024 to run synchronously, the drive shaft 022 can be rotated, thereby realizing flexible control of wire winding and unwinding. This design has smooth transmission, low noise, and is easy to adjust speed and maintain, and can adapt to the conveying needs of different wire diameters and materials.

[0027] Furthermore, it also includes a trajectory correction component, disposed on the side wall of the first side plate 011 and positioned between the wire feeding component and the straightening and forming mechanism. The trajectory correction component includes a horizontal shaft 03, fixed on the first side plate 011; and an adjusting screw 031, fixed to the end of the horizontal shaft 03 and screwed with two threaded sleeves 032, with the two threaded sleeves 032 positioned on both sides of the wire. By adjusting the position of the two threaded sleeves 032, the correction of the wire feeding process can be achieved. Figure 1 As shown.

[0028] Example 3 In another embodiment of the present invention, each straightening assembly 04 includes a side clamping block assembly and a straightening wheel assembly. The side clamping block assembly includes a rectangular box 041 fixed to the side wall of the bracket 012, two slide rails 042 disposed on the top of the rectangular box 041, and two sliders 043 slidably mounted to each slide rail 042. Each slider 043 is rotatably mounted with a swing arm 045 via a pin 044. A back plate 046 is fixed between the two swing arms 045 distributed on the same side. A clamping block 047 is connected to the inner side of each back plate 046, and the two clamping blocks 047 can... It can act on the outer side of the two vertical segments of the U-shaped code wire; it also includes two first lifting cylinders 048 arranged in a figure-eight pattern, and a first hinge member 0410 provided at one end of each first lifting cylinder 048 is hinged to a first hinge seat 0411 provided on the side wall of the corresponding back plate 046 through a first connecting shaft, and a second hinge member provided at the other end is hinged to a second hinge seat 0416 provided at the bottom of the rectangular box 041 through a second connecting shaft; and two clearance slots 049 opened on both sides of the top of the rectangular box 041, respectively for the passage of the two first lifting cylinders 048.

[0029] like Figure 8 , 9 As shown, the straightening assembly 04 in this embodiment consists of side clamping block assemblies on both sides and a straightening wheel assembly on the top. It is known that the two back plates 046 containing the side clamping block assemblies are distributed on both sides of the wire, and each of the two back plates 046 has a clamping block 047 on its inner side. The outer sides of each back plate 046 are connected to the corresponding first lifting cylinder 048 via a first hinge seat 0411 and a first hinge member 0410. The other ends of the two first lifting cylinders 048 are respectively hinged to the inner bottom of the rectangular box 041 and arranged in a V-shape. Figure 8 , 9 As shown, when the two first lifting cylinders 048 extend and retract, they can precisely clamp and guide the vertical section of the U-shaped code wire from both sides, effectively eliminating lateral bending of the wire and improving straightening accuracy and adaptability.

[0030] It is worth noting that the clamping block 047 here is preferably made of rubber to reduce damage to the surface of the wire during clamping.

[0031] Furthermore, the straightening wheel assembly includes a mounting bracket 0412 fixed to the top of the rectangular box 041, a second lifting cylinder 0413 mounted on the mounting bracket 0412, and an assembly ring 0414 disposed at the telescopic end of the second lifting cylinder 0413. The assembly ring 0414 is located inside the top of the mounting bracket 0412 and is equipped with a rotatable straightening wheel body 0415. The straightening wheel body 0415 can act on the inner side of the U-shaped code wire.

[0032] like Figure 8 , 9As shown, the straightening wheel 0415 is assembled inside the assembly ring 0414 and is lifted by the second lifting cylinder 0413. When the straightening wheel 0415 acts on the inside of the wire, it can flexibly press and guide the wire to ensure the straightness and cross-sectional consistency of the wire in multiple dimensions. The lifting cylinders in this application are all equipped with a locking device to ensure stable stopping after extension and retraction, which is a mature existing technology.

[0033] Example 4 In another embodiment of the present invention, the pre-forming flattening assembly includes a third lifting cylinder 052 disposed on the upper part of the bracket 012, a third end plate 053 connected to the telescopic end of the third lifting cylinder 052, and an assembly frame 054 disposed at the bottom of the third end plate 053; a plurality of pressure rollers 055 linearly assembled inside the assembly frame 054 and acting on the inner side of the U-shaped code wire; and a drive housing 05 disposed on the lower part of the bracket 012. The drive housing 05 is distributed in a U-shape, wherein a plurality of drive rollers 051 are horizontally installed inside, and a drive structure is provided on one side for driving the plurality of drive rollers 051 to rotate synchronously and convey the U-shaped code wire forward.

[0034] like Figure 1 , 7 As shown in Figure 8, the pre-forming flattening assembly in this embodiment uses several pressure rollers 055 and several drive rollers 051 that cooperate with each other. The pressure rollers 055 can be linearly assembled in the assembly frame 054 to apply uniform pressure to the inner side of the wire. Combined with the synchronous conveying of the drive rollers 051, the wire can be pre-sorted and flattened after straightening, which significantly improves the flatness and cross-sectional shape stability of the wire before it enters the punching process.

[0035] It is worth noting that the drive housing 05 here is equipped with existing structures such as motors and synchronous belts, which enable several drive rollers 051 to rotate synchronously, in the same direction and at the same speed, further realizing the assisted pushing of U-shaped code wires.

[0036] Example 5 In another embodiment of the present invention, the moving blade assembly includes: a mounting side plate 07 fixed to one side of the base 01; two sets of blanking blade structures symmetrically distributed on the upper and lower sides of the base 01, each set of blanking blade structures including a rotating shaft 071, an eccentric roller 072 fixed to one end of the rotating shaft 071, and a rotating wheel 073 sleeved on the outer periphery of the eccentric roller 072, wherein the eccentric roller 072 is eccentrically distributed with respect to the rotating shaft 071; a mounting member 074 is provided on one side of the rotating wheel 073, and the mounting member 074... The first cutter 075 is installed on the 4, and a U-shaped frame 076 is provided on the other side of the rotating wheel 073; and a fixing plate 077 is fixed to the side wall of the assembly side plate 07; it also includes a telescopic rod 079, which is provided in the telescopic hole 078 opened in the middle of the fixing plate 077, and one end of the telescopic rod 079 passes through the telescopic hole 078 and extends downward for a certain distance, and the other end is fixed upward with an I-shaped sleeve 0710, which is built into the U-shaped frame 076 and slides with the U-shaped frame 076 in a limited position.

[0037] Furthermore, the driving component includes: two meshing transmission gears 0711, respectively fixed to one end of the two rotating shafts 071 away from the eccentric roller 072; a side block, assembled on the base 01 and with a drive motor 0712 mounted on top, the output shaft of the drive motor 0712 being fixed to the end of one of the rotating shafts 071.

[0038] like Figure 1 , 10 As shown, the present invention designs the rotating shaft 071 and the eccentric roller 072 to be eccentrically distributed. When the rotating shaft 071 rotates, the telescopic rod 079 can move longitudinally relative to the telescopic hole 078, while the I-shaped sleeve 0710 on it can move laterally relative to the U-shaped frame 076. This allows the eccentric roller 072 to drive the rotating wheel 073, the mounting part 074, and the first cutter 075 to move in a parabolic trajectory. That is, the punching frequency of the moving blade assembly can be matched with the linear speed of the wire feeding assembly in real time. Specifically, while the wire feeding assembly continuously feeds the pre-formed wire forward, the first cutter 075 completes the "cut-in-punch-return" action in a very short cycle. The whole process does not require deceleration or stopping, which fundamentally solves the production capacity bottleneck caused by the "one step, one stop" of traditional punching machines.

[0039] In addition, the drive unit uses two meshing transmission gears 0711 fixed on two rotating shafts 071 respectively. When the drive motor 0712 drives one of the rotating shafts 071, the other rotating shaft 071 rotates synchronously and in the opposite direction through the meshing characteristics. This design ensures that the upper and lower sets of punching blades maintain a symmetrical reciprocating motion trajectory at any time. The upper and lower first cutters 075 can cut into the wire from the upper and lower sides at the same time, forming a "scissor-like" cutting force, which greatly reduces the single-blade driving force required for punching, and the cut is free from tensile deformation. It is particularly suitable for continuous separation of U-shaped wire without stopping the machine.

[0040] Example 6 In another embodiment of the present invention, a wire end punching assembly is also provided on the top of the bracket 012 for punching the head end of the U-shaped code wire; the wire end punching assembly includes: a top plate 08, fixed on the top of the bracket 012; a first horizontal rail 081 and a second horizontal rail 083, respectively fixed on the upper and lower surfaces of the top plate 08, a first horizontal block 082 and a second horizontal block 084 respectively mounted on the first horizontal rail 081 and the second horizontal rail 083, an assembly frame 085 connected to the first horizontal block 082 and the second horizontal block 084; and a fourth lifting cylinder 087, assembled on the bottom of the assembly frame 085 and provided with a fourth end plate 088 at the telescopic end; a second cutter 089 is also provided at the bottom of the fourth end plate 088; and a telescopic cylinder 086 is provided on the surface of the top plate 08, and the telescopic end of the telescopic cylinder 086 is connected to the first horizontal block 082.

[0041] like Figure 2 , 3 As shown, this invention sets up an independent wire end punching component after the wire leaves the straightening and forming mechanism, which can pre-punch the first end of the U-shaped wire, effectively removing the bending, indentation or uneven end caused by unwinding, handling or threading. This design ensures that the first end of the wire is flat and neat, and guarantees the stability and consistency of the processing quality of the entire production line from the source. Specific examples Figure 2 As shown, the sliding guide rail pair formed by the first horizontal rail 081, the second horizontal rail 083, the first horizontal block 082, and the second horizontal block 084, in conjunction with the drive of the telescopic cylinder 086, enables the second cutter 089 to actively move laterally along the direction perpendicular to the wire conveying direction. At the same time, the fourth lifting cylinder 087 drives the second cutter 089 to perform vertical lifting and punching actions. The dual-axis linkage design of lateral movement and lifting makes this wire end punching component not only adaptable to the punching requirements of different wire diameters and end positions, but also allows for quick adjustment of the punching starting point during equipment debugging or model change, exhibiting strong flexibility and adaptability.

[0042] In this invention, unless otherwise explicitly specified and limited, the terms "installation", "connection", "joining", "fixing" and other such terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

Any non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the invention shall fall within the scope of protection of the present invention.
