[0001] The utility model relates to the technical field of wire cutting, in particular to a tension control mechanism of wire cutting equipment. Background Art

[0002] In the field of metal processing, cutting metal wire is a basic and critical process in the manufacturing industry. In the field of wire processing and manufacturing, wire cutting equipment is one of the indispensable key equipment, used to cut wire to meet specified sizes or other requirements. In these application scenarios, wire tension control is directly related to cutting accuracy and production efficiency.

[0003] The common method of adjusting the wire tension during cutting is to drive a pressure roller to move vertically, causing it to bend the wire and gradually tighten it to achieve the control effect. However, in practice, it is found that only controlling the position of the pressure roller to adjust the wire will cause the position where the wire is conveyed by the rollers at both ends to become loose, which will have a certain impact on the tension control. Utility Model Content

[0008] An adjusting component is used to adjust the tension of the wire. The adjusting component is arranged on the top of the support. The adjusting component includes a U-shaped frame and an auxiliary roller. A notch is opened on the top of the support. The U-shaped frame is slidably arranged inside the notch, and the auxiliary roller is rotatably arranged inside the U-shaped frame.

[0009] In a possible design, the transmission component also includes a servo motor, which is fixedly arranged on one side of the bracket, and one end of the rotating shaft rotates and passes through the bracket. The output shaft of the servo motor is fixedly arranged on one end of one of the rotating shafts, and the outer wall of the rotating shaft is fixedly sleeved with a gear, and the two gears on the same side of the displacement are engaged with each other.

[0011] In a possible design, the adjustment assembly also includes two arc-shaped clamping plates, grooves are provided on both sides of the top of the support, and the two grooves are connected to the guide groove, the two arc-shaped clamping plates are respectively located inside the two grooves, and an inner rod No. 1 is fixedly provided at both ends of the bottom of the arc-shaped clamping plate, and the bottom end of the inner rod No. 1 slides through to the bottom of the support.

[0012] In a possible design, a connecting rod is fixedly provided at the bottom of the U-shaped frame, a No. 1 outer cylinder is slidingly sleeved on the outer wall of the No. 1 inner rod, a same spring is fixedly provided between the bottom end of the No. 1 inner rod and the bottom inner wall of the No. 1 outer cylinder, a same connecting plate is fixedly provided at the bottom of the four No. 1 outer cylinders and the bottom of the connecting rod, an electric telescopic rod is fixedly provided at the top of the base, and the output shaft of the electric telescopic rod is fixedly provided at the bottom of the connecting plate.

[0014] In a possible design, a plurality of guard plates are fixedly provided on the top of the support, and a concave surface is provided on the bottom of the guard plates, and the concave surface cooperates with the guide groove.

[0028] Reference Figure 1 A tension control mechanism, which is used in the field of wire cutting, includes: a base and a support: the base 1 serves as the supporting foundation of the entire mechanism, and a support 5 is fixedly set in the middle of its top. A cutting mechanism 15 is set on the top of the support 5 for cutting the wire. The cutting mechanism 15 is an existing technology, and the cutting effect is achieved by controlling the movement of the cutting blade by a cylinder.

[0029] Reference Figure 1-2 Transmission assembly: The transmission assembly is used to transmit wires and is set on both sides of the top of the base 1. The transmission assembly includes two brackets 2, which are fixed on the base 1, and the support 5 is located between the two brackets 2.

[0030] In addition, the transmission component also includes a servo motor 7, which is fixedly arranged on one side of the bracket 2. The output shaft of the servo motor 7 is fixedly connected to one end of one of the rotating shafts 3 to realize power transmission. The outer wall of the rotating shaft 3 is also fixedly sleeved with a gear 6. The two gears 6 on the same side are engaged to ensure the synchronous rotation of the rollers 4 on both sides. The outer wall of one of the rotating shafts 3 on both sides is also fixedly sleeved with a synchronous wheel. The two synchronous wheels are connected by a synchronous belt 8 to realize the synchronous operation of the transmission components on both sides.

[0031] The present application can be used in the field of wire cutting, and can also be used in other fields applicable to the present application.

[0032] Example 2

[0033] refer to Figure 3 , improved on the basis of Example 1: a tension control mechanism of a wire cutting equipment, which is applied to the field of wire cutting, an adjusting component: the adjusting component is used to adjust the tension of the wire, and is arranged on the top of the support 5. The adjusting component includes a U-shaped frame 13 and an auxiliary roller 14. The U-shaped frame 13 is slidably arranged in the recess 12 opened on the top of the support 5, and the auxiliary roller 14 is rotatably arranged inside the U-shaped frame 13. By adjusting the position of the U-shaped frame 13 when clamping and fixing the two ends of the wire, the pressing effect of the auxiliary roller 14 on the wire can be changed, thereby adjusting the tension of the wire.

[0034] Reference Figure 4 The top of the support 5 and the extension plate 17 and the bottom inner wall of the U-shaped frame 13 are all provided with guide grooves 10 to facilitate the smooth transmission of the wire.

[0035] Reference Figure 4-5 At the same time, grooves 9 are provided on both sides of the top of the support 5, which are connected to the guide groove 10. An arc-shaped splint 11 is provided inside the groove 9. The No. 1 inner rod 21 at both ends of the arc-shaped splint 11 slides through the support 5, and the outer wall below the support 5 is slidingly sleeved with a No. 1 outer cylinder 18. A spring 24 is provided between the bottom end of the No. 1 inner rod 21 and the inner wall of the bottom of the No. 1 outer cylinder 18. The bottoms of the four No. 1 outer cylinders 18 and the bottom of the connecting rod 20 fixedly provided below the U-shaped frame 13 are fixedly connected to the same connecting plate 22, and the bottom of the connecting plate 22 is fixedly connected to the output shaft of the electric telescopic rod 23.

[0036] Specifically, the wire passes between the two rollers 4 on one side of the adjustment component and is connected to the other two rollers 4 along the guide groove 10. The rollers 4 are rotated by driving the servo motor 7, so that the wire is clamped and conveyed. When the tension of the wire needs to be adjusted in preparation for cutting, the electric telescopic rod 23 is driven, and the electric telescopic rod 23 drives the connecting plate 22 to move downward. The connecting plate 22 drives the No. 1 outer cylinder 18 and the connecting rod 20 downward together. The connecting rod 20 drives the U-shaped frame 13 downward, and the No. 1 inner rod 21 and the arc-shaped clamping plate 11 above the No. 1 outer cylinder 18 will also fall down. When the outer wall of the auxiliary roller 14 touches the wire , the arc-shaped splint 11 just clamps the wire, and then continues to drive the electric telescopic rod 23. At this time, when the spring 24 continues to move downward, since the arc-shaped splint 11 cannot move downward, the spring 24 will be gradually stretched, and the arc-shaped splint 11 will obtain a downward pulling force to press the wire. The No. 1 inner rod 21 and the No. 1 outer cylinder 18 will be relatively stretched. At the same time, the connecting rod 20 drives the U-shaped frame 13 downward, so that the auxiliary roller 14 will gradually pull the wire down. Since the two ends are fixed, the wire tension can be controlled by moving the position of the connecting rod 20, avoiding the traditional phenomenon of looseness caused by only adjusting the middle of the wire without fixing the two ends.

[0037] Two round rollers 19 are also rotatably provided inside the notch 12, located on both sides of the U-shaped frame 13 to reduce friction during sliding. In addition, a plurality of guard plates 16 are fixedly provided on the top of the support 5, and the concave surface opened at the bottom of the guard plates 16 cooperates with the guide groove 10 to ensure that the wire can be smoothly transmitted.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the servo motor 7 and the electric telescopic rod 23 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
