Description

Technical Field

[0001] This utility model relates to the technical field of wire rod processing equipment, and more specifically, to an S-shaped feeding device for wire rod processing. Background Technology

[0002] The S-roller, also known as the tension roll, is an important piece of equipment in the tension system. Its main function is to generate friction at the wrap angle by winding the strip around the S-roller, thereby adjusting the changes in the outlet and inlet tensions and thus changing the tension value. The design and operation of the S-roller have a significant impact on product quality. Therefore, precise control of the S-roller's operation is the key to ensuring production quality.

[0003] In the prior art, when feeding wire rod, the driving wheel below the S roller drives the driven wheel above to rotate. The preload is determined by the driving and driven relationship of the S roller and the contact area between the workpiece and the roller. General equipment cannot display the magnitude of the preload, thus failing to guarantee product quality. Furthermore, different models of wire rod require driving wheels of different diameters, and it is inconvenient to replace the driving wheel in the existing equipment.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by designing an S-shaped feeding device for wire rod processing.

[0006] The technical solution of this utility model to achieve the above objectives is an S-shaped feeding device for wire rod processing, including a fixed frame, a drive wheel rotatably mounted on the lower end of the fixed frame, an electric motor mounted on one side of the lower end of the fixed frame, the electric motor driving the drive wheel to rotate, a stress relief mechanism mounted on the fixed frame, and a detection mechanism mounted on the fixed frame.

[0007] The stress relief mechanism includes a lifting frame mounted on the upper end of a fixed frame, and a driven wheel is rotatably mounted on the upper end of the lifting frame. The driving wheel and the driven wheel are connected by a transmission belt.

[0008] The detection mechanism includes a contact tachometer installed on the upper end of the lifting frame. One end of the driven wheel has a connection hole, and the detection end of the contact tachometer extends into the connection hole.

[0009] Furthermore, the lifting frame includes lifting platforms located on both sides above the fixed frame. The two lifting platforms are connected by multiple fixed rods. Guide rods are installed on both sides of the lower surface of the lifting platform. Guide holes are opened on both sides of the upper end of the fixed frame. One end of the guide rod extends into the guide hole. Multiple limiting holes are opened on the guide rod. A positioning hole is opened on one side of the guide hole. A positioning pin is installed in the positioning hole. One end of the positioning pin can extend into the limiting hole.

[0010] Furthermore, a lifting rod is installed in the middle of the two lifting platforms, lifting racks are installed on both sides of the lower end of the lifting rod, a rotating rod is provided below the lifting rod, rolling bearings are installed at both ends of the rotating rod, the rolling bearings are installed on the fixed frame, rotating gears are installed at both ends of the rotating rod, the rotating gears mesh with the lifting racks, and a rotating handle is installed at one end of the rotating rod.

[0011] Furthermore, the electric motor includes a DC motor mounted on a fixed frame, a frequency converter connected to the DC motor, a reducer mounted on the rotating end of the DC motor, and the power output end of the reducer connected to the drive wheel.

[0012] Furthermore, the drive wheel has multiple limiting grooves of varying depths.

[0013] The beneficial effects of this utility model are as follows: By installing a contact-type tachometer on the driven wheel, the rotational speeds of the driving and driven wheels can be detected. With a fixed contact area between the wire rod and the driving wheel, the preload applied to the workpiece by the S-roller can be adjusted by controlling the rotational speed of the driving wheel. The value is displayed by the contact-type tachometer, which facilitates adjustment. The driven wheel is designed to be height-adjustable, so when replacing the driving wheel, the driven wheel position can be lowered, making it easier to loosen the transmission belt and replace the driving wheel. Connecting the driving and driven wheels via the transmission belt also reduces the stress on the driving wheel and extends the service life of the device. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] This utility model provides, for example Figure 1-4 An S-shaped feeding device for wire rod processing is shown, comprising a fixed frame 1, a drive wheel 2 rotatably mounted on the lower end of the fixed frame 1, a motor 3 mounted on one side of the lower end of the fixed frame 1, the motor 3 driving the drive wheel 2 to rotate, a stress relief mechanism mounted on the fixed frame 1, and a detection mechanism mounted on the fixed frame 1; the stress relief mechanism includes a lifting frame 4 mounted on the upper end of the fixed frame 1, a driven wheel 5 rotatably mounted on the upper end of the lifting frame 4, the drive wheel 2 and the driven wheel 5 being connected by a transmission belt 6; the detection mechanism includes a contact tachometer 7 mounted on the upper end of the lifting frame 4, a connection hole 8 opening at one end of the driven wheel 5, and the detection end of the contact tachometer 7 extending into the connection hole 8;

[0022] The feeding process of this device is as follows: the wire rod is wound around the outside of the drive wheel 2 and tightened. The motor 3 is started to drive the drive wheel 2 to rotate. Through the friction between the drive wheel 2 and the wire rod, the wire rod can be fed. The position of the driven wheel 5 is adjusted by the lifting frame 4, which can tighten the transmission belt 6. When the drive wheel 2 rotates, the driven wheel 5 can be rotated through the transmission belt 6, which can distribute the stress on the drive wheel 2 and extend the service life of this device. When the driven wheel 5 rotates, the contact tachometer 7 can be rotated, which can facilitate the detection of the rotation speed and the determination of the preload. When the drive wheel 2 needs to be replaced, the position of the driven wheel 5 is lowered by the lifting frame 4, and then the transmission belt 6 can be loosened, which can facilitate the replacement of the drive wheel 2.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The lifting frame 4 includes lifting platforms 9 located on both sides above the fixed frame 1. The two lifting platforms 9 are connected by multiple fixed rods 10. Guide rods 11 are installed on both sides of the lower surface of the lifting platform 9. Guide holes 12 are opened on both sides of the upper end of the fixed frame 1. One end of the guide rod 11 extends into the guide hole 12. Multiple limiting holes 13 are opened on the guide rod 11. A positioning hole 14 is opened on one side of the guide hole 12. A positioning pin 15 is installed in the positioning hole 14. One end of the positioning pin 15 can extend into the limiting hole 13.

[0024] The process of the lifting frame 4 driving the driven wheel 5 to move up and down is as follows: by moving the guide rod 11 up and down in the guide hole 12, the lifting platform 9 can drive the driven wheel 5 to move up and down. The guide rod 11 and the guide hole 12 can ensure the direction of movement of the lifting platform 9. After the position is adjusted, one end of the positioning pin 15 is passed through the positioning hole 14 and extended into the limit hole 13 to position the lifting platform 9.

[0025] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 A lifting rod 16 is installed between the two lifting platforms 9. Lifting racks 17 are installed on both sides of the lower end of the lifting rod 16. A rotating rod 18 is provided below the lifting rod 16. Rolling bearings 19 are installed at both ends of the rotating rod 18 and are mounted on the fixed frame 1. Rotating gears 20 are installed at both ends of the rotating rod 18 and mesh with the lifting racks 17. A rotating handle 21 is installed at one end of the rotating rod 18. When the lifting platform 9 is moved up and down, the operator rotates the rotating rod 18 by rotating the handle 21. The rotating rod 18 can drive the rotating gears 20 to rotate. The rotating gears 20 mesh with the lifting racks 17 and can drive the lifting racks 17 to move up and down, thereby enabling the lifting rod 16 and the lifting platform 9 to move up and down.

[0026] Refer to the instruction manual appendix Figure 1The motor 3 includes a DC motor 22 mounted on a fixed frame 1. A frequency converter 23 is connected to the DC motor 22. A reducer 24 is mounted on the rotating end of the DC motor 22. The power output end of the reducer 24 is connected to the driving wheel 2. It is controlled by an external controller. When the contact tachometer 7 detects that the rotation speed of the driven wheel 5 is too fast or too slow, the controller controls the frequency converter 23 to adjust the circuit, thereby adjusting the rotation speed of the DC motor 22. After being reduced in speed by the reducer 24, it can drive the driving wheel 2 to rotate.

[0027] Refer to the instruction manual appendix Figure 1 The drive wheel 2 has multiple limiting grooves 25 with different depths. Different types of wire rods can be placed into different limiting grooves 25 to feed different types of wire rods, which increases the applicability of this device.
