Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blade processing, specifically relating to a mechanically rolling thin-part straight blade leveling device. Background Technology
[0002] In the field of machining, cutting tools are important processing tools, and their precision and performance have a crucial impact on the processing quality. During the manufacturing process of cutting tools, due to factors such as uneven distribution of internal stress in the material, cutting force during processing, and heat treatment, cutting tools are prone to deformation problems such as bending and warping, which affect the performance of the cutting tools.
[0003] When leveling blades, conventional leveling devices typically use a fixed number of leveling rollers. These rollers have a relatively simple structure, generally consisting of only a single support structure and a leveling structure. During the leveling process, conventional leveling devices often only apply pressure to one side of the blade. Although they can compress both the upper and lower sides of the blade, the pressure applied is asymmetrical. On the one hand, applying pressure only to one side of the blade or applying pressure at a fixed position makes it difficult to completely remove the stress at both ends of the blade, resulting in residual stress inside the blade. In subsequent use, this residual stress may cause the blade to deform again, affecting its service life and accuracy. On the other hand, because it is impossible to alternately apply pressure to both ends of the blade, the blade is easily affected by unilateral pressure during the leveling process, causing the blade to bend to one side. This not only reduces the leveling effect but may also damage the blade. Utility Model Content
[0004] To overcome the problem that the blade leveling device is difficult to apply pressure evenly to the upper and lower ends of the blade during use, which may lead to residual stress or damage to the blade, a mechanical rolling thin-part straight blade leveling device is proposed.
[0005] The technical solution of this utility model is as follows: a mechanically rolling thin-part straight blade leveling device, comprising a bearing device and a leveling structure. Several leveling structures distributed left and right are installed on the bearing device. Each leveling structure includes a base, with a frame 1 and a frame 2 distributed left and right fixed to the upper end of the base. A support roller 1 is rotatably installed on the inner walls of the front and rear ends of frame 1. An electric cylinder 1 is fixed to the center of the upper inner wall of frame 1. A movable frame 1 is fixed to the output end of electric cylinder 1. A leveling roller 1 is rotatably installed on the inner walls of the front and rear ends of movable frame 1. The lower outer wall of leveling roller 1 is in contact with the upper outer wall of support roller 1. A support roller 2 is rotatably installed on the inner walls of the front and rear ends of frame 2. An electric cylinder 2 is fixed to the center of the lower inner wall of frame 2. A movable frame 2 is fixed to the output end of electric cylinder 2. A leveling roller 2 is rotatably installed on the inner walls of the front and rear ends of movable frame 2. The upper outer wall of leveling roller 2 is in contact with the lower outer wall of support roller 2. The upper outer wall of support roller 1 and the lower outer wall of support roller 2 are flush.
[0006] Furthermore, the bearing device includes a support base, the upper end of which has several slots equidistant from left to right, and a screw hole fixed to the lower inner edge of the slot.
[0007] Furthermore, a locking block is fixed to the lower end of the base. The locking block is adapted to the slot. A screw hole is provided through the locking block. The locking block is fixed in the slot by bolts.
[0008] Furthermore, a bracket is fixed to the left end of the support base, and a guide plate is fixed to the upper end of the bracket. The upper end of the guide plate is flush with the upper outer wall of the support roller.
[0009] Furthermore, a servo motor is fixed to one side of the outer wall of frame one, and the output end of the servo motor is connected to one side of the rotating shaft of support roller one. Gear one is fixed to the other side of the rotating shaft of support roller one, and gear two is fixed to the rotating shaft of support roller two.
[0010] Furthermore, gear two meshes with gear one, a protective cover is fixed to the outer wall of frame one, gear one and gear two are both located inside the protective cover, and a connecting plate is fixed to the upper edge of the base, with the upper end of the connecting plate flush with the lower outer wall of support roller two.
[0011] Furthermore, the bearing device is also equipped with a material guiding structure, which includes an adjusting seat. A second locking block is fixedly connected to the lower end of the adjusting seat. A screw hole three is opened through the second locking block. The second locking block is adapted to the slot and is fixed in the slot by bolts. A second guide plate is fixedly connected to the upper end of the adjusting seat.
[0012] The beneficial effects of this utility model are as follows: The output end of the electric cylinder one can drive the movable frame to press down, so that the leveling roller one fits against and presses the upper outer wall of the support roller one, thus pressing and flattening the upper surface of the blade. The output end of the electric cylinder two can drive the movable frame two to rise, so that the leveling roller two fits against and presses the lower outer wall of the support roller two, thus pressing and flattening the lower surface of the blade. The several leveling structures distributed on the left and right can continuously and evenly press and flatten the blade alternately from top to bottom. Compared with the existing blade leveling device, the added leveling structure can be driven by the electric cylinder to drive the leveling roller in conjunction with the support roller to alternately level the upper and lower ends of the blade, which can reduce the probability of blade deformation when pressing the blade surface and improve the leveling quality.

In use, by gear 214 meshing with gear 213, the servo motor 212 can simultaneously drive support roller 204 and support roller 208 to transport the leveling blade. The protective cover 215 can protect gear 213 and gear 214, improving their service life. The connecting plate 218 can... The adjacent leveling structure 2 is connected to facilitate the conveying of leveling blades. The carrying device 1 is also equipped with a material guiding structure 3, which includes an adjusting seat 301. The lower end of the adjusting seat 301 is fixedly connected to a second locking block 302. A screw hole 303 is provided through the second locking block 302.

[0025] During operation, firstly, select an appropriate number of leveling structures 2 according to the blade requirements. Place the leveling structures 2 sequentially and at equal intervals on the upper end of the support base 101, aligning the locking block 216 with the opening of the slot 102. Push the base 201 to slide the locking block 216 into the slot 102, aligning the corresponding screw hole 103 with the screw hole 217.

Align the corresponding screw hole 103, rotate the bolt to fix the guide structure 3, then start all the servo motors 212, so that the output end of the servo motors 212 drives the support roller 204 to rotate, thereby driving the gear 213 to mesh with the gear 214 to rotate, so that the support roller 208 and the support roller 204 rotate synchronously in opposite directions. Finally, place the blade that needs to be leveled on the guide plate 105, push the blade into the support roller 204, start all the electric cylinders 205 and 209, clamp and level the blade, and wait for the blade to slide out from the guide plate 204.

The output end of electric cylinder 209 can drive movable frame 210 to rise, so that leveling roller 211 fits against the lower outer wall of support roller 208, pressing and flattening the lower end face of the blade. The several leveling structures 2 distributed on the left and right can continuously and evenly press and flatten the blade alternately from top to bottom, solving the problem that the blade leveling device is difficult to apply pressure evenly to the upper and lower ends of the blade during use, which may lead to residual stress or damage to the blade.
