Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment of a leveler, and particularly relates to an oxide scale discharge device for a leveler. Background Art

[0002] Leveling machines are mainly used for leveling various cold-rolled and hot-rolled plates and various workpieces. During the leveling process of plates and flat workpieces, the oxide scale attached to the surface of the plates and workpieces is repeatedly bent and rolled by the leveling machine roller system, and then falls off from the plate surface and accumulates on the support rollers under the lower working roller and on the bed. Excessive accumulation of oxide scale will cause the wear of the working rollers and support rollers to increase, the equipment accuracy to decrease, and the service life of the working rollers and support rollers to shorten. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the utility model provides an oxide scale discharging device for a leveling machine, which can timely discharge the oxide scale that falls off the surface of the plate during the leveling process from the equipment, ensuring the long-term stable and precise operation of the leveling machine and extending the service life of the working roller and the supporting roller.

[0004] The utility model is realized through the following technical solutions:

[0005] A scale discharge device for a leveling machine comprises a frame, a lower working roller is installed on the frame, a lower supporting roller is arranged below the lower working roller, and the lower supporting roller is installed on a lower supporting roller seat. The device is characterized in that a power shaft is installed on one side of the frame, a tensioning shaft is installed on the other side of the frame, a plurality of annular belts are sleeved on the power shaft and the tensioning shaft, the annular belts are arranged between two adjacent lower supporting roller seats, and a material dumping box installed on one side of the frame is arranged below the annular belt.

[0006] The power shaft is installed in the power shaft bearing seat through the power shaft bearing, the power shaft bearing seat is fixed on the first support, and the power shaft is driven by the reduction motor.

[0007] The tensioning shaft is installed in the tensioning shaft bearing seat through the tensioning shaft bearing, and the tensioning shaft bearing seat is fixed on the second support.

[0008] The tensioning shaft bearing seat is fixed on the second support through a waist-shaped hole, a tensioning adjustment block is fixed on the side of the second support, a tensioning screw is installed on the tensioning adjustment block, and the front end of the tensioning screw presses against the side of the tensioning shaft bearing seat.

[0009] A locking nut is installed on the tensioning screw.

[0010] Limiting clamps are arranged on both sides of the endless belt.

[0011] The limiting clamping ring is formed by connecting two semicircular clamping rings.

[0012] The beneficial effect of the utility model is that the oxide scale that falls off the plate during the plate straightening process is continuously transmitted out from the inside of the equipment through multiple sets of rotating annular belts, thereby avoiding the accumulation of oxide scale inside the roller system, improving the long-term stable operation accuracy of the equipment, and extending the service life of the working rollers and support rollers in the roller system.

DETAILED DESCRIPTION

[0020] The accompanying drawings are a specific embodiment of the utility model. The embodiment includes a power shaft 5, a tensioning shaft 6, an endless belt 7, a limiting clamp ring 20 and a dump box 8. The power shaft 5 is installed on one side of the equipment inlet and outlet, and is fixed to the frame 1 through the first support 11; the tensioning shaft 6 is installed on the other side of the equipment inlet and outlet, and is fixed to the frame 1 through the second support 15. A plurality of endless belts 7 of the same length are sleeved on the power shaft 5 and the tensioning shaft 6. The position of the tensioning shaft 6 is horizontally adjustable, and the endless belt 7 can be tensioned. The power shaft 5 drives the endless belt 7 to rotate cyclically by rotating itself; the endless belt 7 is arranged between the two lower support roller seats 4, and the length range exceeds the range of the lower working roller 2. The oxide scale falling from the upper part can be transmitted out of the equipment through cyclic rotation, and falls to the dump box 8 below for centralized collection and treatment. The limiting clamp ring 20 is installed on the power shaft 5 and the tensioning shaft 6, and is arranged on both sides of the endless belt 7 to limit the position of the endless belt 7 and prevent the position of the endless belt 7 from deviating during the rotation process.

[0021] Both ends of the power shaft 5 are installed on two power shaft bearing seats 10 through power shaft bearings 9, and the power shaft bearing seats 10 are fixed to two first supports 11 by screws, and the first supports 11 are fixed to the frame 1. The reduction motor 12 is installed on one of the first supports 11, connected to the power shaft 5, and drives the power shaft 5 to rotate.

[0022] The two ends of the tensioning shaft 6 are installed on the two tensioning shaft bearing seats 14 through the tensioning shaft bearings 13. The two tensioning shaft bearing seats 14 are fixed to the two second supports 15 by screws. The second support 15 is fixed to the frame 1. The tensioning shaft 6 is parallel to the power shaft 5. The hole for fixing the tensioning shaft bearing seat 14 on the second support 15 is a waist-shaped hole 16. The position of the tensioning shaft bearing seat 14 on the second support 15 is adjustable. The adjustment direction makes the tensioning shaft 6 away from the power shaft 5. Two tensioning adjustment blocks 17 are fixed to the sides of the two second supports 15 by screws. The tensioning adjustment blocks 17 are processed with thread holes for installing tensioning screws 18. The head of the tensioning screw 18 is against the tensioning shaft bearing seat 14. The tensioning screw 18 is used to adjust the position of the tensioning shaft bearing seat 14, thereby realizing the position adjustment of the tensioning shaft 6. After the tensioning screw 18 is adjusted, the locking nut 19 can be used to lock and fix the position.

[0023] A limit snap ring 20 is composed of two semicircular snap rings 21, and the two semicircular snap rings 21 are assembled into a limit snap ring 20 by screws, so that the limit snap ring 20 is conveniently installed on the power shaft 5 and the tensioning shaft 6. After the limit snap ring 20 is installed, a certain gap is left between the two semicircular snap rings 21, so that the limit snap ring 20 is tightly wrapped on the power shaft 5 and the tensioning shaft 6.
