Abstract
Description
Technical Field
[0001] This invention relates to the field of rolling equipment technology, and more specifically, to a rolling device and rolling process for metal surface processing. Background Technology
[0002] Roller burnishing cutters can use the plastic deformation of metal at room temperature to smooth out the micro-unevenness of the workpiece surface, thereby changing the surface structure, mechanical properties, shape and size. Most metal surface rolling devices on the market are not convenient for clamping and fixing the metal objects to be ground, and it is not convenient to adjust the position of the metal objects to be ground, resulting in low working efficiency of metal grinding.
[0003] A search revealed a rolling mill for metal surface processing based on an adjustable component, disclosed in publication number CN112975270A. The mill includes a support mechanism; two moving mechanisms are symmetrically slidably connected to the top of the support mechanism; each moving mechanism is rotatably connected to a clamping mechanism; a metal object to be polished is clamped and fixed between the two clamping mechanisms; a robotic arm is fixedly mounted on the top of the support mechanism; and a rolling component is fixedly mounted on one end face of the robotic arm. Through the design of a second motor, pressure plate, rotating shaft, fixed frame, drive rod, and anti-slip clamp, the output shaft of the second motor drives the clamping mechanism to rotate. Rotating the drive rod moves the anti-slip clamp, which is attached to the rolling surface of the metal object, away from the metal object, facilitating rolling and polishing of the surface. This allows for rapid rolling and polishing of multiple surfaces, improving the rolling efficiency of the metal object and reducing the labor intensity of the operator.
[0004] However, this rolling mill for metal surface processing requires the metal object to be rolled to be suspended in the air between two pressure plates. During the rolling operation, the two pressure plates are subjected to a large vertical load, and their bearing load is prone to breakage. At the same time, by rotating multiple sets of drive rods, the anti-slip clamps are made to contact and detach from the metal surface, which means that the entire device can only clamp metal materials of a specified size. The operation is cumbersome, the applicability is poor, and the working efficiency of rolling rectangular metal grinding objects is reduced. Summary of the Invention

[0019] The advantages of this invention are:
[0020] 1. This invention uses a second robotic arm to clamp the metal material to be rolled and place it on the worktable surface. Rotating the annular plate drives the first arc-shaped guide plates to rotate, squeezing the corresponding first guide balls, causing each slider to slide along the corresponding groove, thereby driving the clamping plate and clamping frame to clamp the metal material. This facilitates quick clamping and fixing of the metal material. In this clamping and fixing method, the bottom of the metal material is placed on the worktable surface, avoiding the clamping components from being subjected to vertical load during the rolling and grinding process. The operation is simple and improves the clamping efficiency of the metal material.
[0021] 2. When the metal to be rolled is a cuboid, after operation T1, the cuboid metal material is clamped along the two opposite sides corresponding to the long side. The two auxiliary clamping members slide along the arc groove, driving the second arc guide plate to slide, thereby squeezing the corresponding second guide ball, causing the guide post to slide along the guide opening, thereby driving the two auxiliary plates to clamp the other two opposite sides of the cuboid metal material. It is suitable for clamping and fixing rectangular metal materials of different sizes, improving the applicability of the device while improving the clamping efficiency of the metal material.
[0022] 3. After the rolling and polishing of one surface of the metal material is completed, the first clamping member and the second clamping member are released. The metal material is clamped and lifted vertically by controlling the second robotic arm. The starting brake motor drives the rotation of the drive gear, which in turn drives the electric gripper to rotate downwards. After flipping the metal material, the metal material is placed on the worktable surface, realizing the rolling and polishing of all surfaces of the metal material, thus improving the practicality of the device.

The annular plate 37 is rotated counterclockwise, thereby driving each of the first arc-shaped guide plates 41 to rotate, squeezing the corresponding first guide balls 35, so that each slider 30 slides along the corresponding slide groove 5, thereby driving the clamping plate 31 and the clamping frame 32 to clamp the metal material, which facilitates quick clamping and fixing of the metal material. In this clamping and fixing method, the bottom of the metal material is placed on the surface of the worktable 4, avoiding the clamping parts from being subjected to vertical loads during the rolling and grinding process. The force is simple to operate and improves the clamping efficiency of metal materials. During the rotation of the annular plate 37, the first pawl 44, the first ratchet 42 and the first connecting spring 46 work together to lock the annular plate 37 by rotating counterclockwise.

6. A rolling process using the rolling apparatus for metal surface processing as described in claim 5, characterized in that, Includes the following steps: T1. The metal material to be rolled is clamped and placed on the surface of the worktable (4) by the second robotic arm (14). The ring plate (37) is rotated to drive each first arc guide plate (41) to rotate, and each first guide ball (35) is squeezed, so that each slider (30) slides along the corresponding slide groove (5), thereby driving the clamping plate (31) and the clamping frame (32) to clamp the metal material. T2. When the metal to be rolled is a cuboid, after the operation of T1, the cuboid metal material is clamped along the two opposite sides corresponding to the long side, and the arc plate (55) slides along the arc groove (48), which drives the second arc guide plate (58) to slide, thereby squeezing the corresponding second guide ball (53), so that the guide column (51) slides along the guide opening (50), thereby driving the two auxiliary plates (52) to clamp the other two opposite sides of the cuboid metal material. T3. After clamping and limiting the metal material, control the first robotic arm (2) to drive the rolling component (3) to roll the metal surface; T4. After the rolling of one surface of the metal material is completed, the first clamping part (9) and the second clamping part (10) are released. The metal material is clamped and lifted vertically by controlling the second mechanical arm (14). The starting brake motor (16) is controlled to drive the rotation of the drive gear (17), which in turn drives the electric gripper (18) to rotate downwards. After flipping the metal material, the metal material is placed on the surface of the worktable (4). The above operation is repeated to achieve rolling of each surface of the metal material.
