Description

Technical Field

[0001] This utility model relates to the field of automated wire conveying equipment, specifically to a wire conveying power mechanism. Background Technology

[0002] This technical solution relates to the field of automated wire conveying equipment, and is specifically applied to the conveying process of various wires such as wires, cables, and metal wires during processing. It is commonly used in automated production scenarios such as terminal crimping, wire cutting, and winding. It is mainly used to cooperate with subsequent processing equipment to achieve precise feeding and retraction of wires in specific processes, so as to ensure the continuous operation of the production process.

[0003] Existing technologies already exist for wire conveying devices that combine a cylinder-driven clamping structure with a motor-driven feeding structure. However, these devices have significant drawbacks in actual use. Cold heading machines typically require manual assistance to thread the wire into the straightening machine. When the equipment is stopped suddenly or the wire is changed midway, manual unloading is usually necessary, and the unloading length is also quite long. This is time-consuming and labor-intensive in small-batch, high-frequency production, which seriously affects production and maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a wire conveying power mechanism. It solves the technical problem that cold heading machines generally require manual assistance to thread the wire into the straightening machine, and manual material removal is usually required when the equipment is stopped suddenly or the wire is changed in the middle, which seriously affects the production and maintenance efficiency.

[0005] The purpose of this utility model is achieved through the following means: a wire conveying power mechanism, including a frame, a cylinder fixedly mounted on one side of the frame by screws, a push head connected to the output end of the cylinder, a wire feeding mechanism provided on the inner wall of the frame, a swing support provided on the inner wall of the wire feeding mechanism near the cylinder, the push head connected to the swing support via a rotating shaft, a swing shaft provided at the bottom of the inner wall of the wire feeding mechanism on one side of the swing support, the swing support mounted on the inner wall of the wire feeding mechanism via the swing shaft, a driven shaft movably mounted on the swing support via a bushing, a driven gear fixedly connected to the bottom of the driven shaft, a swing wire feeding wheel provided through the wire feeding mechanism at the top of the driven shaft, a motor mounted on the inner wall of the frame via a mounting bracket, a rotating sleeve meshing with the power output end of the motor, a drive shaft fixedly inserted into the rotating sleeve, a drive gear fixedly provided on the inner wall of the drive shaft, and a fixed wire feeding wheel provided through the wire feeding mechanism at the top of the drive shaft.

[0006] The cylinder is fixed to the frame with screws to ensure a stable installation. The cylinder drives the swing support to rotate around the swing shaft through the push head, thereby adjusting the position of the swing wire feeding wheel. The motor drives the drive shaft to rotate through the meshing transmission with the rotating sleeve. The drive shaft drives the drive gear and the fixed wire feeding wheel to rotate simultaneously. The drive gear then meshes with the driven gear, driving the driven shaft and the swing wire feeding wheel to rotate synchronously. Finally, the wire is fed through the cooperation of the swing wire feeding wheel and the fixed wire feeding wheel.

[0007] Furthermore, the frame is provided with V-shaped guide tubes on both sides of the swing wire feeding wheel and the fixed wire feeding wheel, and the outer wall of the frame is provided with guide wheels on the side of the wire inlet.

[0008] The V-shaped guide tubes on both sides of the oscillating wire feed wheel and the fixed wire feed wheel limit and guide the wire through the V-shaped structure, ensuring that the wire enters accurately between the two wire feed wheels; the guide wheel on the wire inlet side pre-guides the wire before it enters the frame, preventing the wire from affecting subsequent conveying due to its own bending or deviation.

[0009] Furthermore, a deep groove ball bearing is fitted at the connection between the swing shaft and the swing support, and both ends of the swing shaft are fixed to the inner wall of the wire feeding mechanism by the shaft shoulder.

[0010] The deep groove ball bearing at the connection between the swing shaft and the swing support can convert the sliding friction between the two into rolling friction, reducing rotational resistance.

[0011] Furthermore, the bushing is an oil-lubricated self-lubricating bushing, and its inner wall is in clearance fit with the driven shaft.

[0012] During the rotation of the driven shaft, lubricating oil can automatically seep out and form an oil film between the bushing and the driven shaft, achieving self-lubrication; the clearance fit between the bushing and the driven shaft provides sufficient space for the rotation of the driven shaft, avoiding rotation jamming due to excessive tightness.

[0013] Furthermore, the outer wall of the wire feeding mechanism is provided with a strip-shaped observation window, in which a transparent acrylic plate is embedded, and the acrylic plate is sealed and fixed to the outer wall of the wire feeding mechanism with sealant.

[0014] The strip-shaped observation window on the outer wall of the wire feeding mechanism, together with the transparent acrylic plate, allows operators to directly observe the wire feeding process and the operating status of the components inside the wire feeding mechanism; the sealant seals the acrylic plate to the outer wall of the wire feeding mechanism, preventing external dust and impurities from entering the wire feeding mechanism.

[0015] Furthermore, the bottom of the swing support is provided with a limiting block, which is fixedly connected to the inner wall of the wire feeding mechanism.

[0016] The limiting block at the bottom of the swing support is fixed to the inner wall of the wire feeding mechanism. When the cylinder pushes the swing support to rotate around the swing shaft, the limiting block can prevent the swing support from continuing to swing downward and limit its maximum swing amplitude.

[0017] The beneficial effects of this utility model are as follows: the wire conveying power mechanism uses a cylinder to drive the push head, which in turn drives the swing support to move around the swing axis. Under the action of the cylinder, the swing wire feeding wheel clamps and releases the wire. The motor, as a power source, drives the fixed wire feeding wheel to rotate via the drive shaft. Thus, under the combined action of the cylinder and the motor, the wire clamping, feeding, or unloading functions are realized. The cylinder pushes the swing support to swing around the swing axis, thereby realizing the opening and closing action between the swing wire feeding wheel and the fixed wire feeding wheel. The motor, as a power source, drives the wire feeding wheel to rotate via the drive gear. Thus, when the wire feeding wheel is closed, it can clamp the wire. The drive gear meshes with the driven gear to realize power-assisted feeding. When the motor reverses, it can realize the wire unloading action. Compared with the original manual feeding and unloading, adding a wire conveying power mechanism in front of the straightening machine saves time and effort when changing wires.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-3The specific implementation of the wire conveying power mechanism includes a frame 100. A cylinder 101 is fixedly mounted on one side of the frame 100 by screws. A push head 102 is connected to the output end of the cylinder 101. A wire feeding mechanism 103 is provided on the inner wall of the frame 100. A swing support 104 is provided on the inner wall of the wire feeding mechanism 103 near the cylinder 101. The push head 102 is connected to the swing support 104 via a rotating shaft. A swing shaft 105 is provided at the bottom of the inner wall of the wire feeding mechanism 103 on one side of the swing support 104. The swing support 104 is mounted on the inner wall of the wire feeding mechanism 103 via the swing shaft 105. A driven shaft 106 is movably mounted on the swing support 104 via a bushing. A driven gear 107 is fixedly connected to the bottom of the driven shaft 106. A swing wire feeding wheel 108 is provided at the top of the driven shaft 106 through the wire feeding mechanism 103. A motor 109 is mounted on the inner wall of the frame 100 via a mounting bracket. A rotating sleeve 110 is meshed with the power output end of the motor 109. A drive shaft 111 is fixedly inserted into the rotating sleeve 110. A drive gear 112 is fixedly provided on the inner wall of the drive shaft 111 located in the wire feeding mechanism 103. A fixed wire feeding wheel 113 is provided at the top of the drive shaft 111 through the wire feeding mechanism 103.

[0022] The cylinder 101 is fixed to the frame 100 with screws to ensure that the cylinder 101 is installed securely. The cylinder 101 drives the swing support 104 to rotate around the swing shaft 105 through the push head 102, thereby adjusting the position of the swing wire feeding wheel 108. The motor 109 drives the drive shaft 111 to rotate through the meshing transmission with the rotating sleeve 110. The drive shaft 111 drives the drive gear 112 and the fixed wire feeding wheel 113 to rotate at the same time. The drive gear 112 then meshes with the driven gear 107, driving the driven shaft 106 and the swing wire feeding wheel 108 to rotate synchronously. Finally, the wire is fed through the cooperation of the swing wire feeding wheel 108 and the fixed wire feeding wheel 113.

[0023] The frame 100 is equipped with V-shaped guide tubes on both sides of the oscillating wire feed wheel 108 and the fixed wire feed wheel 113, and the outer wall of the frame 100 is equipped with guide wheels on the side of the wire inlet.

[0024] The V-shaped guide tubes on both sides of the oscillating wire feed wheel 108 and the fixed wire feed wheel 113 limit and guide the wire through the V-shaped structure, ensuring that the wire accurately enters between the two wire feed wheels; the guide wheel on the wire inlet side pre-guides the wire before it enters the frame 100, preventing the wire from affecting subsequent conveying due to its own bending or deviation.

[0025] A deep groove ball bearing is fitted at the connection between the swing shaft 105 and the swing support 104, and both ends of the swing shaft 105 are limited and fixed to the inner wall of the wire feeding mechanism 103 through the shaft shoulder.

[0026] The deep groove ball bearing at the connection between the swing shaft 105 and the swing support 104 can convert the sliding friction between the two into rolling friction, thereby reducing rotational resistance.

[0027] The bushing is an oil-lubricated self-lubricating bushing, and its inner wall is clearance-fitted with the driven shaft 106.

[0028] During the rotation of the driven shaft 106, lubricating oil can automatically seep out and form an oil film between the bushing and the driven shaft 106, achieving self-lubrication; the clearance fit between the bushing and the driven shaft 106 provides sufficient space for the rotation of the driven shaft 106, avoiding rotation jamming due to excessive tightness.

[0029] The outer wall of the wire feeding mechanism 103 is provided with a strip-shaped observation window, and a transparent acrylic plate is embedded in the observation window. The acrylic plate is sealed and fixed to the outer wall of the wire feeding mechanism 103 by sealant.

[0030] The strip-shaped observation window on the outer wall of the wire feeding mechanism 103, together with the transparent acrylic plate, allows the operator to directly observe the wire feeding situation and component operation status inside the wire feeding mechanism 103; the sealant seals the acrylic plate to the outer wall of the wire feeding mechanism 103, which can prevent external dust and impurities from entering the interior of the wire feeding mechanism 103.

[0031] The bottom of the swing support 104 is provided with a limiting block, which is fixedly connected to the inner wall of the wire feeding mechanism 103.

[0032] The limiting block at the bottom of the swing support 104 is fixed to the inner wall of the wire feeding mechanism 103. When the cylinder 101 pushes the swing support 104 to rotate around the swing shaft 105, the limiting block can prevent the swing support 104 from continuing to swing downward and limit its maximum swing amplitude.

[0033] The working process of the wire conveying power machine in this embodiment is as follows: When the wire conveying power mechanism is working, the cylinder 101 is first fixed to the frame 100 with screws. The push head 102 at the output end of the cylinder 101 drives the swing support 104 on the inner wall of the wire feeding mechanism 103 to rotate around the swing shaft 105, thereby adjusting the position of the swing wire feeding wheel 108 connected to the top of the driven shaft 106, realizing its opening and closing with the fixed wire feeding wheel 113. At the same time, the motor 109 mounted on the inner wall of the frame 100 through the mounting bracket has its power output end meshing with the rotating sleeve 110, driving the drive shaft 111 fixedly inserted into the rotating sleeve 110 to rotate. The drive shaft 111 drives the drive gear 112 located on the inner wall of the wire feeding mechanism 103 to rotate. On the one hand, the driving gear 112 drives the fixed wire feeding wheel 113 at the top to rotate, and the driving gear 112 meshes with the driven gear 107 at the bottom of the driven shaft 106, driving the driven shaft 106 and the swinging wire feeding wheel 108 to rotate synchronously. During this period, the V-shaped guide tubes on both sides of the two wire feeding wheels and the guide wheel on the side of the wire inlet on the frame 100 guide the wire. The limiting block at the bottom of the swing support 104 limits its maximum swing amplitude. The oil-containing self-lubricating bushing assists the driven shaft 106 to rotate smoothly. Finally, through the cooperation of the swinging wire feeding wheel 108 and the fixed wire feeding wheel 113, under the control of the cylinder 101 clamping and the power provided by the motor 109, the wire is clamped and fed or unloaded when the motor 109 reverses, without the need for manual assistance in threading and unloading.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
