Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, specifically to a steel wire clamp for a steel wire feeding switching system. Background Technology

[0002] In the production of steel cord, raw steel wire needs to be released from the I-beams and fed into the production line. The wire feeding switching system is located at the beginning of the production line, i.e., the raw material supply section. In order to ensure that the production line can continue to operate even when the steel wire on the I-beams is used up, the existing technology has designed a wire feeding switching system.

[0003] Current wire feeding switching systems include a working I-beam reel for winding the working steel wire and a spare I-beam reel for winding the spare steel wire. The spare steel wire is connected end-to-end with the working steel wire. As the working steel wire is continuously released, its end is pulled and, through a series of mechanisms, the column rotates, switching the positions of the two I-beam reels, allowing the spare steel wire to be pulled accordingly. Examples include Chinese patent CN202211702955.2, titled "A Self-Retracting Water Tank Wire Drawing Machine with Non-Stop Reel Changing," and Chinese patent CN202321187078.X, titled "Swing Arm Type Automatic Wire Feeding Device Suitable for Forward and Reverse Winding of Steel Wire."

[0004] In this type of wire feeding switching system, during the normal wire feeding process of the working I-beam reel, the end of the working wire and the beginning of the spare wire need to be in a relatively fixed state to prevent the wires from loosening. Therefore, a wire clamping mechanism is set below the guide wheel 18. The wire clamping mechanism generally includes two parts: a clamping plate 14 corresponding to the working I-beam reel and a clamping bar 15 corresponding to the spare I-beam reel (see...). Figure 5 The clamping plate 14 includes a vertically arranged fixed clamping plate and a movable clamping plate, which are connected by bolts. The fixed clamping plate and the movable clamping plate fix the steel wire located between them by friction. When the working steel wire on the working I-beam is almost exhausted, the pulling force applied by the swing arm 16 can overcome the friction between the fixed clamping plate and the movable clamping plate, thereby pulling the steel wire out of the clamping plate 14 and pulling the guide wheel 18 on the column 17 down to trigger the control component to drive the column 17 to rotate, thereby realizing the switching of the two I-beams. The clamping bar 15 includes a fixed clamping bar and a movable clamping bar arranged parallel to the I-beam. When the spare working wheel switches to the working position, the swing arm 16 will continue to apply pulling force to pull the spare steel wire out between the fixed clamping bar and the movable clamping bar, so that the spare steel wire on the spare working wheel can continue to be used.

[0005] The swing arm rotates around the circumference of the I-beam to pick up the wire, while the clamping bar is set parallel to the I-beam. During the rotation of the swing arm, the tension applied to the wire is mainly upward, and the outward force (i.e. at the clamping bar) is very small. When the spare wire is released from the clamping bar, it will generate excessive instantaneous force, which poses a safety hazard. In addition, the wire may get stuck on the clamping bar and cannot be ejected, resulting in the wire being pulled off. The process of reconnecting broken wires seriously affects the stability of the alloy process, increases the labor intensity of personnel, and poses a high safety risk. Utility Model Content

[0006] The purpose of this utility model is to provide a wire clamp for a wire feeding switching system, which enables the wire to smoothly detach from the clamp under the pull of the swing arm, effectively reducing the phenomenon of the clamp breaking the wire, reducing safety hazards, ensuring the stability of the alloy production process, and reducing the labor intensity of operators.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a wire clamp for a wire feeding switching system, including a connector, a clamping plate on the connector, an elastic wire clamping member on the clamping plate, one end of the elastic wire clamping member being fixedly connected to the clamping plate, the clamping plate being inclined, with the end of the clamping plate having the elastic wire clamping member being higher than the end of the clamping plate not having the elastic wire clamping member.

[0008] A further improvement of this utility model is that it also includes an auxiliary component, which includes a bolt. The clamping strip and the elastic clamping wire are coaxially provided with through holes. The shank of the bolt passes through the through holes and is threaded with a nut. A spring is provided between the nut and the elastic clamping wire and sleeved on the bolt.

[0009] A further improvement of this utility model is that the clamping strip forms a 30° angle with the horizontal plane.

[0010] A further improvement of this utility model is that the higher end of the clamping strip is laterally offset from its lower end.

[0011] A further improvement of this invention is that the lateral offset angle is 15°.

[0012] A further improvement of this utility model is that the connecting member includes an integrally formed vertical part and a horizontal part, and a horizontal plate is fixedly provided at one end of the clamping strip, and the horizontal plate is connected to the horizontal part by bolts.

[0013] A further improvement of this utility model is that the elastic wire clamping component includes a clamping piece, one end of which is provided with an arc surface to facilitate the pulling out of the steel wire.

[0014] A further improvement of this utility model is that the elastic wire clamping component further includes a clamp, the thickness of which is greater than the thickness of the clamping piece and is located between the clamping piece and the clamping strip, and one end of the clamp is provided with an inclined surface to facilitate the pulling out of the steel wire.

[0015] A further improvement of this utility model is that the nut is a wing nut.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, by setting the clamping plate at an inclination, allows the steel wire to overcome the friction of the elastic clamping component under the pull of the swing arm and move along the inclined clamping plate, thus smoothly detaching from the clamping bar. This effectively reduces the phenomenon of the clamping bar breaking the steel wire, reduces safety hazards, ensures the stability of the alloy production process, and reduces the labor intensity of operators.

[0018] This invention improves the clamping stability of the elastic wire clamp by setting auxiliary components, and allows adjustment of the spring compression level by adjusting the nut, thereby adjusting the clamping force applied to the wire, which is convenient for control and adjustment.

[0019] In this invention, the higher end of the clamping bar is laterally offset from the lower end. During the rotation of the swing arm, the position of the contact point between the steel wire and the clamping bar changes continuously, thereby reducing the force required to directly pull out the steel wire, reducing the resistance encountered by the swing arm when pulling the steel wire, and improving the smoothness of the steel wire release.

[0020] In this invention, the elastic wire clamping component includes a clamping plate and a clamping head. The clamping head is thicker than the clamping plate and can apply a greater clamping force. The clamping position is determined based on the thickness of the steel wire, either between the clamping plate and the clamping head or between the clamping plate and the clamping head. For wires with a diameter less than 1.48 mm, the clamping position is generally chosen between the clamping plate and the clamping head, while for wires with a diameter greater than 1.48 mm, the clamping position is chosen between the clamping plate and the clamping head. This improves clamping stability and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0028] Combination Figures 1-5 It is known that a wire clamp for a wire feeding switching system includes a connector 1, a clamp plate 2 on the connector 1, and an elastic wire clamp 3 that cooperates with the clamp plate 2. One end of the elastic wire clamp 3 is fixedly connected to the clamp plate 2. The clamp plate 2 is inclined, and the end with the elastic wire clamp 3 is higher than the end without the elastic wire clamp 3.

[0029] It also includes auxiliary components, including a bolt 4, a clamping plate 2, and an elastic wire clamping member 3, all coaxially provided with through holes. The shank of the bolt 4 passes through the through hole and is threadedly connected to a nut 5. A spring 6 is provided between the nut 5 and the elastic wire clamping member 3, and is sleeved on the bolt 4. Preferably, the nut 5 is a wing nut, which is convenient for rotational adjustment.

[0030] The clamping plate 2 forms an angle of 10° to 40° with the horizontal plane, preferably 30°. This ensures sufficient clamping force while also guaranteeing that the steel wire has enough lateral force to help it disengage from the clamp when pulled.

[0031] Optionally, the higher end of the clamping bar 2 is laterally offset from its lower end. The clamping bar 2 is rotated horizontally by a certain angle before being tilted, forming a composite angle of both tilt and rotation. This lateral offset, based on the rotation direction of the swing arm, makes it easier for the steel wire to find the correct exit direction when pulled, reducing the possibility of it getting stuck in the clamping bar. The lateral offset angle is 5° to 30°, preferably 15°.

[0032] The connector 1 includes an integrally formed vertical part 7 and a horizontal part 8. A horizontal plate 9 is fixedly provided at one end of the clamping strip 2, and the horizontal plate 9 is connected to the horizontal part 8 by bolts. The vertical part 7 can be connected to the bracket of the existing wire clamping strip installation location. An elastic wire clamping member is provided on the upper surface of one end of the clamping strip 2, which cooperates with the upper surface to clamp the wire, and the other end of the clamping strip 2 is provided with the horizontal plate 9.

[0033] The elastic wire clamp 3 includes a clamping piece 10, one end of which is provided with an arc surface 11 to facilitate the pulling out of the steel wire. This makes the steel wire release more smoothly and reduces friction.

[0034] Preferably, the elastic wire clamping component 3 further includes a clamp 12, the thickness of which is greater than the thickness of the clamping plate 10 and is located between the clamping plate 10 and the clamping strip 2. One end of the clamp 12 is provided with an inclined surface 13 to facilitate the pulling out of the steel wire. Optionally, the surface of the clamp 12 facing the clamping strip 2 is provided with a notch, the width of which is smaller than the diameter of the steel wire. The notch can improve the clamping and fixing effect on the steel wire, preventing the steel wire from coming loose due to poor clamping force before being pulled by the swing arm. Preferably, both the clamping plate 10 and the clamp 12 are made of metal. Optionally, both the clamping plate 10 and the clamp 12 are made of alloy steel.

[0035] The working principle of the wire clamping bar in the wire feeding switching system provided by the utility model is as follows: When fixing the wire, the clamping position is determined according to the wire thickness, either between the clamping bar plate 2 and the clamp 12 or between the clamping plate 10 and the clamp 12. Wires with a diameter less than 1.48 mm are generally clamped between the clamping plate 10 and the clamp 12, while wires with a diameter greater than 1.48 mm are clamped between the clamping bar plate 2 and the clamp 12. The stability of the clamping is improved by adjusting the auxiliary components. When the swing arm 16 pulls the wire to overcome the clamping force, the wire can be guided to move along the inclined direction of the clamping bar plate 2, facilitating the wire's release and allowing for smooth wire detachment.
