Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a device for controlling the tail size of materials in roll forming. Background Technology

[0002] In the continuous roll forming production line of sheet metal, there are strict precision requirements for the control of the cross-sectional dimensions of the product, especially the tail dimension of the profile, the accuracy of which directly affects the splicing quality, installation accuracy and overall aesthetics of the product.

[0003] Currently, the industry commonly uses a pre-shearing forming method, where the sheet material is first sheared to a fixed length before being rolled and bent. However, in this method, when the equipment performs the final processing on the tail end of the sheet material, the inherent elasticity of the material causes a springback effect the moment it leaves the mold. This springback leads to an open angle and dimensional deviation in the formed tail end, failing to meet the process design requirements. Specifically, this manifests as insufficient tail edge angle, incomplete closure, and a noticeable opening, resulting in uneven profile splicing, excessive gaps, and a series of other problems. Current solutions typically involve manual adjustment. Utility Model Content

[0004] This invention provides a device for controlling the tail dimension of materials in roll forming, which can effectively solve the above-mentioned problems.

[0005] This utility model is implemented as follows: This utility model provides a device for controlling the tail dimension of material in roll forming, comprising: The frame has an adjustment component on its upper surface and a disc wheel assembly on one side. A guide wheel assembly is provided between the disc wheel assembly and the frame. The adjustment component has a ball screw, and a guide wheel rotating block is rotatably provided at the upper end of the guide wheel assembly. The guide wheel rotating block is slidably disposed on the ball screw to change the included angle between the guide wheel assembly and the disc wheel assembly.

[0006] As a further improvement, the frame includes a support base, fixing blocks, and a first fixing plate; two fixing blocks are fixedly arranged at intervals on the upper surface of the support base, and the support base is provided with a first fixing plate on both sides of the wheel assembly, and each first fixing plate is provided with an arc-shaped sliding groove.

[0007] As a further improvement, the adjustment assembly is also provided with a motor and an adjustment rotating block; the adjustment rotating block is rotatably mounted on the fixed block, the adjustment rotating block is sleeved on the ball screw, and the end of the ball screw away from the disc wheel assembly is connected to the motor.

[0008] As a further improvement, the guide wheel assembly is provided with two second fixing plates spaced apart, and a guide wheel group is provided between the two second fixing plates. Each second fixing plate is provided with a slider at a position close to the arc-shaped sliding groove, and a guide wheel rotating block is rotatably provided at the upper end of the second fixing plate.

[0009] As a further improvement, the disc wheel assembly includes an upper disc wheel assembly and a lower disc wheel assembly, with the lower disc wheel assembly disposed at the bottom of the support base and the upper disc wheel assembly disposed above the lower disc wheel assembly.

[0010] As a further improvement, the upper disc wheel assembly includes an upper disc wheel and a first support frame, the first support frame being fixed to the support base, and the other end of the first support frame being provided with an upper disc wheel.

[0011] As a further improvement, the lower disc wheel assembly is provided with a second support frame, which is fixed to the support base by a fixing seat. The other end of the second support frame is provided with a lower disc wheel, and a support block is fixedly connected to the lower end of the second support frame. An adjusting screw is provided at the end of the second support frame away from the lower disc wheel.

[0012] The beneficial effects of this utility model are: This invention uses a motor-driven ball screw to slide the guide wheel rotating block, thereby precisely and continuously adjusting the angle between the guide wheel assembly and the disc wheel assembly. This dynamic adjustment applies a precise compensating force the instant the material's tail leaves the mold, effectively counteracting the material's elastic rebound and ensuring the accuracy and consistency of the tail bending angle. This fundamentally eliminates the "opening" phenomenon, resulting in neat profile splicing and tight gaps, significantly improving the final product quality and aesthetics. Compared to traditional manual adjustments relying on experience, the motor-driven adjustment method allows for rapid and accurate adjustments, reducing reliance on skilled workers, saving labor costs, and avoiding instability and random errors caused by human operation. Furthermore, the device has a wide adjustment range and fast response speed, flexibly adapting to the processing needs of different specifications and materials of sheet metal. When product specifications need to be changed during production, rapid switching can be achieved, significantly reducing equipment downtime and improving the overall production line efficiency.

[0024] Reference Figure 1-7 As shown, a device for controlling the tail dimension of material in roll forming includes: The machine frame 1 has an adjustment component 2 on its upper surface and a disc wheel assembly on one side. A guide wheel assembly 3 is located between the disc wheel assembly and the machine frame 1. The adjustment component 2 has a ball screw 23. A guide wheel rotating block 33 is rotatably mounted on the upper end of the guide wheel assembly 3. The guide wheel rotating block 33 is slidably mounted on the ball screw 23 to change the angle between the guide wheel assembly 3 and the disc wheel assembly. The ball screw 23 is driven by a motor to slide the guide wheel rotating block 33, thereby precisely and continuously adjusting the angle between the guide wheel assembly 3 and the disc wheel assembly. This dynamic adjustment can apply a precise compensation force at the moment the material tail leaves the mold, effectively counteracting the elastic rebound of the material, ensuring the accuracy and consistency of the tail bending angle, and fundamentally eliminating the opening phenomenon.

[0025] Furthermore, referring to Figure 5 and Figure 6As shown, in order to stabilize the device structure, a frame 1 is provided. The frame 1 mainly includes a support base 11. Two fixing blocks 12 are fixed at intervals on the upper end surface of the support base 11. In addition, on one side of the support base 11, and on both sides of the wheel assembly 3, a first fixing plate 13 for connecting the wheel assembly 3 is provided. Each first fixing plate 13 has an arc-shaped sliding groove. The arc-shaped sliding groove provides the running trajectory and guidance for the swing adjustment of the wheel assembly 3, and is used to limit the swing range of the wheel assembly 3.

[0026] Furthermore, referring to Figure 2 and Figure 4 As shown, in order to precisely adjust the guide wheel assembly 3, an adjustment assembly 2 is provided. The adjustment assembly 2 mainly includes a motor 21, an adjustment rotating block 22, and a ball screw 23. The adjustment rotating block 22 is equipped with a bearing and is rotatably mounted between two fixed blocks 12 via a rotating shaft. The adjustment rotating block 22 is sleeved on the ball screw 23. The end of the ball screw 23 away from the disc wheel assembly is connected to the motor 21. A coupling is provided between the ball screw 23 and the motor 21, and the ball screw 23 can be driven to rotate by the motor 21. Therefore, when the motor 21 is started, the adjustment rotating block 22 rotates in accordance with the change of the tilt angle of the ball screw 23.

[0027] Furthermore, referring to Figure 4 and Figure 5 As shown, in order to apply precise force to the tail of the material, a guide wheel assembly 3 is provided.

The entire guide wheel assembly 3 can slide along an arc-shaped trajectory; at the upper end of the second fixed plate 31, a guide wheel rotating block 33 is rotatably provided. The inside of the guide wheel rotating block 33 is provided with a threaded hole that matches the ball screw 23. When the ball screw 23 rotates, the guide wheel rotating block 33 moves back and forth along the ball screw 23, thereby driving the guide wheel assembly 3 to swing, thereby adjusting the angle between the guide wheel assembly 3 and the disc wheel group. By adjusting the angle, the pressure of the device on the plate is adjusted, thereby avoiding the rebound effect caused by the elastic properties of the material itself when processing the tail of the plate.

[0028] Furthermore, the disc wheel assembly is the main component in material forming, and it is divided into an upper disc wheel assembly 4 and a lower disc wheel assembly 5, as shown in the reference.

The second support frame 53 is mounted on the support base 11 via the fixed base 54. The lower disc wheel 51 is connected to the end of the second support frame 53 away from the support base 11, and the support block 52 is connected to the lower end face of the second support frame 53. The support block 52 is also fixedly connected to the support base 11. The support block 52 is used to improve the structural strength of the second support frame 53. An adjusting screw 55 is also provided at the end of the second support frame 53 away from the lower disc wheel 51. The upper disc wheel assembly 4 is located above the lower disc wheel assembly 5, and includes an upper disc wheel 41 and a first support frame 42.
