Description

Technical Field

[0001] The invention relates to the field of mechanical processing, and in particular to a material strip straightening device. Background Art

[0002] The metal strip in the continuous die process will naturally bend after electroplating and heat treatment. In addition, in order to facilitate transportation and further batch processing, it will be rolled into a disc shape. Therefore, it will deform and bend before further processing.

[0003] Metal hollow strip is a kind of special-shaped metal strip, which is used in various optical precision instruments, such as mobile phones P30, M30, and D40. The flatness of the metal hollow strip is extremely high. Therefore, during further processing or processing, the flatness of the metal hollow strip needs to be ensured.

[0004] Traditional straightening machines are used to straighten metal strips. For example, stainless steel strips are straightened by directly squeezing them with the straightening rollers in the straightening machine to change their flatness and curvature, thereby achieving the straightening purpose. They cannot be adjusted according to changes in the strip structure. However, due to its hollow structure, metal hollow strips break when subjected to excessive force, and traditional straightening machines almost always straighten strips of a single shape. Therefore, due to its stable extrusion, excessive force will be generated on the hollow structure. The straightening effect and adaptability of the metal hollow strips are poor, and they cannot be used normally.

[0005] For this reason, a new device is urgently needed to solve the above problems. Summary of the invention

[0061] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0062] The metal strip straightening technology in this embodiment is a derivative process of the continuous die process, which is suitable for the production of parts and components in precision electronic equipment, such as terminals, chassis, springs, claws, etc. This embodiment designs a strip straightening device for a metal strip with a hollow structure.

[0063] This embodiment provides a strip straightening device. Figure 1 , 2 As shown, a front view and a rear view of a strip straightening device in this embodiment are shown. The strip straightening device in this embodiment is used for straightening metal strips with hollow structures. The strip straightening device in this embodiment at least includes a mounting bracket 1000, a straightening mechanism 2000, a first driving device 3000, and a second driving device 4000.

[0064] The straightening mechanism 2000 includes a movable roller row and a fixed roller row that are relatively arranged; the movable roller row includes at least two movable roller groups 2200, which are movably installed on the mounting bracket 1000, and the moving direction is perpendicular to the arrangement direction of the two movable roller groups 2200; the fixed roller row includes at least one fixed roller group 2100, which is fixed to the mounting bracket 1000, and a fixed roller group 2100 is arranged at a position relative to the middle of the two movable roller groups 2200.

[0065] The strip straightening device adjusts the distance between the movable roller set 2200 and the fixed roller set 2100 through the first driving device 3000 according to the curvature of the strip to be straightened, and the strip is located between the movable roller row and the fixed roller row; the second driving device 4000 drives the movable roller set 2200 and the fixed roller set 2100 to rotate to convey the strip and realize the straightening of the strip. The strip straightening device in this embodiment adjusts the distance between the movable roller and the fixed roller to match the curvature of the strip, thereby improving the accuracy of the strip straightening. In order to improve the accuracy of straightening the curved portion of the strip, the strip is set between the movable roller set 2200 and the fixed roller set 2100 in the opposite direction of the curved portion, and then the movable roller set 2200 is adjusted according to the curvature of the strip, thereby adjusting the pressure on the metal strip.

[0066] In one embodiment, the material strip is a metal material strip with a hollow structure and is used to make micro-accessories in electronic products. Preferably, for the micro-accessories, the material strip straightening device includes a fixed roller group 2100 and two movable roller groups 2200.

[0067] refer to Figure 3 As shown, a schematic diagram of the structure of the mounting bracket. The mounting bracket 1000 further includes a vertically arranged mounting portion 1100 and a base 1200, the mounting portion 1100 is arranged on the base 1200, and the mounting portion 1100 is used to install the straightening mechanism 2000, the first driving device 3000 and the second driving device 4000. In one embodiment, the mounting portion 1100 includes a mounting surface for installing the straightening mechanism 2000, and an adjustment surface for installing the first driving device 3000 and the second driving device 4000. Of course, the mounting portion 1100 can arrange the straightening mechanism 2000, the first driving device 3000, and the second driving device 4000 on the same surface. It can be implemented according to the assembly environment. Furthermore, the mounting bracket 1000 in this embodiment is provided with at least two slide grooves 1110 and a first through hole 1120, and the two slide grooves 1110 are arranged in parallel on the mounting portion 1100, and the movable roller group 2200 is installed through the slide grooves 1110, and the fixed roller group 2100 is installed through the first through hole 1120. The slide groove 1110 in this embodiment is a U-shaped groove, and of course, the mounting portion 1100 is not limited to only the slide groove 1110 and the first through hole 1120, and as long as various components need to be installed on the mounting bracket 1000, they can be installed by providing a hole-shaped structure on the mounting bracket 1000.

[0068] refer to Figure 4 As shown, the fixed roller assembly 2100 includes a first fixed roller shaft 2110, which is inserted through the mounting bracket 1000 and can rotate along the insertion position. Further, in order to adapt to the installation of the first fixed roller shaft 2110, the mounting bracket 1000 is provided with a first through hole 1120 for inserting the first fixed roller shaft 2110. After the first fixed roller shaft 2110 is inserted into the first through hole 1120, it can rotate along the axial direction of the first through hole 1120. Then, when the first driving device 3000 is connected to the second fixed roller shaft, the second driving device 4000 drives the first fixed roller shaft 2110 to rotate in the first through hole 1120.

[0069] The fixed roller group 2100 includes a first roller 2120, which is sleeved on a first fixed roller shaft 2110 and includes at least two first rollers 2120 with adjustable spacing along the axial direction of the first fixed roller shaft 2110. Further, the fixed roller group 2100 includes at least two first rollers 2120 with adjustable spacing, which are sleeved on the first fixed roller shaft 2110 and can be adjusted axially along the first fixed roller shaft 2110. By adjusting the spacing between the first rollers 2120, the first rollers 2120 are adapted to fit the material belt according to the hollow structure of the material belt. The fixed roller row in this embodiment includes a fixed roller group 2100, which includes two first rollers 2120, and the spacing between the first rollers 2120 is adjusted according to the hollow structure, and the first rollers 2120 rotate with the first fixed roller shaft 2110 to adapt to the movement of the material belt.

[0070] The fixed roller group 2100 includes a plurality of first pressing plates 2130, which are sleeved on the first fixed roller shaft 2110 and located on both sides of each first roller 2120; the first pressing plates 2130 are used to clamp the first roller 2120, and the axial movement and axial rotation of the first roller 2120 along the first roller shaft are limited, thereby satisfying the adjustment and fixation between the first rollers 2120.

[0071] In this embodiment, since the first fixed roller 2110 needs to drive the first roller 2120 to rotate axially, the first roller 2120 needs to be fixed on the first fixed roller 2110, that is, it cannot move or rotate. In this embodiment, the first roller 2120 is clamped and fixed on the first fixed roller 2110 by the first pressing sheet 2130, and the axial movement and axial rotation of the first roller 2120 are stopped, and then when the first fixed roller 2110 rotates, the first roller 2120 is directly driven to rotate, thereby driving the material belt transmission.

[0072] The mounting bracket 1000 in this embodiment is further provided with a support frame 1300, and the support frame 1300 is limitedly sleeved with the first fixed roller 2110 so that the first fixed roller 2110 can be connected to the power device. Among them, since the second movable shaft needs to move along the slide groove 1110, it cannot be stably connected to the power device, and the first fixed roller 2110 in this embodiment is limited in the first through hole 1120. When assembling, it is preferred to connect the first fixed roller 2110 to the power device, and the support frame 1300 is used to reinforce the stability of the assembly of the first fixed roller 2110, and the first fixed roller 2110 needs to receive a power source. Furthermore, the support frame 1300 includes a support portion 1310 and a clamping portion 1320, and semicircular grooves are respectively provided between the support portion 1310 and the clamping portion 1320. When the clamping portion 1320 is fixed to the support portion 1310, the two semicircular grooves form a limiting hole for sleeve-mounting the first fixed roller 2110, thereby realizing the limiting connection of the support frame 1300 with the first fixed roller 2110.

[0073] refer to Figure 5 , 6 As shown, the movable roller set 2200 includes a second movable roller shaft 2210, and a slide groove 1110 is provided on the mounting bracket 1000; the second movable roller shaft 2210 is inserted into the slide groove 1110, and the second movable roller shaft 2210 can move along the slide groove 1110. The movable roller row in this embodiment includes two movable roller sets 2200.

[0074] The movable roller group 2200 includes a second roller 2220, the second roller 2220 is sleeved on the second movable roller shaft 2210, and includes at least two second rollers 2220 with adjustable spacing along the axial direction of the second movable roller shaft 2210. Further, the movable roller group 2200 includes at least two second rollers 2220 with adjustable spacing; the second roller 2220 is sleeved on the second movable roller shaft 2210, and can be adjusted axially along the second movable roller shaft 2210. Further, each movable roller group 2200 includes two second rollers 2220. The corresponding mounting bracket 1000 includes two slide grooves 1110, and the movable roller groups 2200 are respectively mounted.

[0075] The movable roller group 2200 includes a plurality of second pressing plates 2230 , which are sleeved on the second movable roller shaft 2210 and located on both sides of each second roller 2220 ; and,

[0076] When the second roller 2220 rotates under the drive of the second driving device 4000, the second roller 2220 is clamped by the second pressing sheet 2230, and the axial movement and rotation of the second roller 2220 on the second movable roller shaft 2210 are limited. Further, since the second movable roller shaft 2210 needs to drive the second roller 2220 to rotate axially, the second roller 2220 needs to be fixed on the second movable roller shaft 2210, that is, the second roller 2220 can neither move nor rotate on the second movable roller shaft 2210. In this embodiment, the second roller 2220 is clamped and fixed on the second movable roller shaft 2210 by the second pressing sheet 2230, and the axial movement and axial rotation of the second roller 2220 are stopped, so that when the second movable roller shaft 2210 rotates, the second roller 2220 is directly driven to rotate, thereby driving the material belt transmission. At this time, the rotation direction of the second roller 2220 is opposite to that of the first roller 2120, so that both sides of the material belt are transmitted after receiving the transmission force in the same direction, so that the material belt can be initially corrected after being clamped between the first roller 2120 and the second roller 2220.

[0077] When the second roller 2220 rotates with the movement of the material belt, the axial movement of the second roller 2220 on the second movable roller shaft 2210 is limited by the second pressing sheet 2230. Further, since the second movable roller shaft 2210 needs to rotate with the movement of the material belt, the second movable roller shaft 2210 needs to be fixed on the mounting bracket 1000, and the second roller 2220 needs to be axially rotatable on the second roller shaft, that is, the second movable roller shaft 2210 can only move along the slide groove 1110 but cannot rotate, and the second roller 2220 can rotate axially along the second movable roller shaft 2210 but cannot move axially. In this embodiment, the second roller 2220 is limited on the second movable roller shaft 2210 by the second pressing plate 2230, and the axial movement of the second roller 2220 is stopped. Then, when the material belt moves between the first roller 2120 and another set of second rollers 2220, the second roller 2220 on the current second movable roller shaft 2210 is driven to rotate, thereby guiding the correction direction of the material belt, so that the conveyed material belt is clamped between the first roller 2120 and the current second roller 2220 for further correction, so as to ensure the flatness of the material belt after correction.

The slide rail 3210 is provided with a concave portion, and the slider 3220 is provided with a convex portion. The slider 3220 slides along the concave portion on the slide rail 3210 through the convex portion, so that the slider 3220 moves along the slide rail 3210.

[0082] Then, by rotating the screw 3320 to move the screw 3320 relative to the positioning hole, the first connection and the slider 3220 are driven to move along the slide rail 3210, thereby driving the second roller shaft to move along the slide groove 1110; the bolt 3330 is rotated relative to the screw 3320 to limit the movement of the screw 3320.
