Description

Technical Field

[0001] The present invention relates to the technical field of rolling mill component processing, and specifically to a cutting processing method and equipment for the grooves of rolling mill guide and guard rollers. Background Technique

[0002] In the steel rolling production process, the performance of rolling mill guide and guard rollers has a significant impact on the quality and efficiency of steel rolling. The guide and guard rollers use specific grooves on their surfaces to guide and stabilize the running of the rolled piece, and the quality of the grooves is related to whether the rolled piece can be accurately positioned and run smoothly.

[0003] For the existing general processing technology in the market, when dealing with high-end rolling requirements, especially for the problems of oval tube openings of large-diameter guide and guard rollers and non-straight guide and guard rollers, the ordinary processing methods cannot meet the use. The oval shape of the guide and guard rollers will cause problems such as uneven cutting groove depth and inconsistent groove width. If the cutting groove depth is too shallow, the rolled piece will not fit tightly with the grooves of the guide and guard rollers, resulting in unstable running or even deviation of the rolled piece; while if the cutting groove depth is too deep, it may weaken the strength of the guide and guard rollers and affect the service life of the guide and guard rollers. Currently, there is no method and equipment on the market that can solve this problem. How to solve the current situation of inconsistent groove depth and poor dimensional quality during the cutting processing of oval guide and guard rollers is a problem that we need to solve. In addition, some metal chips are easy to adhere to the groove openings after cutting and are not easy to quickly remove. For this, we propose a cutting processing method and equipment for the grooves of rolling mill guide and guard rollers to solve the above problems. Summary of the Invention

[0012] The present invention also discloses a method for floating cutting of the guide roller groove, which specifically includes the following steps: Step 1: Place the guide roller body on the bracket, and slowly push the guide roller forward until its front end reaches one side of the main spindle box. Start the oil cylinder inside the main spindle box to clamp the roller wall of the guide roller body by the upper and lower pressure wheels, so as to ensure the stability of the spiral pipe during operation. The speed reducer in the main spindle box starts to drive the upper and lower pressure wheels to rotate rapidly, and then drives the guide roller body to rotate.

Start the air pump, and the air pump blows air into the blowpipe through the hose, and the air blown out by the blowpipe blows away the metal chips in the groove. Step 4: Start the motor, the motor drives the second bevel gear and the first bevel gear to rotate, and then drives the turntable to rotate, and then the turntable drives the sliding sleeve to rotate in a circle, and the sliding sleeve drives the fixed rod, the rotating plate, and the swing plate to swing back and forth, and the swing plate is used to blow and clean the metal chips in the groove from multiple angles.

[0013] The present invention provides a method and equipment for cutting the guide roller groove of a rolling mill. Compared with the prior art, it has the following beneficial effects: (1) By setting up the floating cutting mechanism, the groove cutting depth can be ensured to be uniform and the groove opening width to be consistent, enabling the rolled piece to fit tightly with the guide roller groove, thus avoiding leakage problems. At the same time, it can prevent weakening the strength of the guide roller due to excessive groove cutting depth, thereby prolonging the service life of the guide roller, improving the safety and stability of the guide roller system, and enhancing the dimensional quality of the guide roller.

[0014] (2) By setting up the downward pressing and locking mechanism, turning the screw rod by rotating the handle can drive the connecting seat and the stabilizing wheel to press the guide roller, thus ensuring the stability of the guide roller during rotation and also meeting the pressing requirements for guide rollers of different sizes.

[0015] (3) By setting up the chip blowing and adjusting component for the groove opening, when using the floating cutting mechanism to cut the groove of the guide roller, it can synchronously blow away and clean the metal chips in the groove opening quickly. Moreover, by pressing the front pressing rod, the depth of the blowing pipe entering the groove opening can be flexibly adjusted according to the depth of the groove opening, achieving a better chip blowing effect. Each time the front pressing rod is pressed, it can penetrate downward for a certain distance, and each time the rear pressing rod is pressed, it can reset upward for a certain distance, with high flexibility.

[0016] (4) By setting up the wind direction adjusting component, through the reciprocating swing of the swing plate, the wind direction in the blowing pipe can be flexibly adjusted, enabling the wind blown out by the blowing pipe to blow the chips in the groove opening from multiple angles, improving the efficiency and effect of chip blowing.

8. Guide roller groove floating cutting method, characterized in that: Specifically, it includes the following steps: Step 1: Place the guard roller body (3) on the bracket, slowly push the guard roller forward until its front end reaches one side of the main spindle box (4), start the oil cylinder inside the main spindle box (4) to clamp the roller wall of the guard roller body (3) with the upper and lower pressure wheels (5), so as to ensure the stability of the spiral pipe during operation. The speed reducer in the main spindle box (4) starts to drive the upper and lower pressure wheels (5) to rotate rapidly, and then drives the guard roller body (3) to rotate; Step 2: Start the cylinder (61) to drive the mounting frame (62) and the two follower wheels (69) to move downward. The follower wheels (69) are in close contact with the outer wall of the guard roller body (3), and at the same time, the cutter head (64) is in contact with the outer wall of the guard roller body (3), and the first spring (67) is compressed. As the guard roller body (3) rotates, the cutter head (64) cuts a groove on the outer wall of the guard roller body (3), and at the same time, the depth of the groove is kept consistent by the setting of the first spring (67); Step 3: By pressing the front pressing rod (84), the pressing rod (84) drives one of the pawls (88) to move downward, and then the pawl (88) drives the ratchet wheel (814) to rotate a certain angle. Then the ratchet wheel (814) drives the gear (815) to rotate, and then the gear (815) drives the rack (810), the vertical bar (811), and the convex column (812) to move downward a certain distance. Then the convex column (812) drives the blowpipe (819) to move downward to make the blowpipe (819) close to the deepest part of the groove. Start the air pump (822), and the air pump (822) blows air into the blowpipe (819) through the hose (823), and the air blown out by the blowpipe (819) blows away the metal chips in the groove; Step 4: Start the motor (911), the motor (911) drives the second bevel gear (912) and the first bevel gear (910) to rotate, and then drives the turntable (97) to rotate. Then the turntable (97) drives the sliding sleeve (99) to perform circular rotation, and the sliding sleeve (99) drives the fixed rod (94), the rotating plate (92), and the swinging plate (93) to perform reciprocating swing, and the metal chips in the groove are cleaned by blowing air from multiple angles by the swinging plate (93).
