Rotating-hoop web-roll type straightener of a straightening cutting machine and straightening method thereof

Abstract

The invention relates to a rotating-hoop web-roll type straightener of a straightening cutting machine and a straightening method thereof. The straightener consists of a motor, a motor belt wheel, a belt, a rotating hoop belt wheel, a bearing stand, a rotating hoop, a locking bolt, a gland bush, an adjusting screw mandril, a lock nut, a roller frame, a roller shaft, a dental plate, an oil nozzle, a bearing, a sleeve, a hyperboloid straightening roll, a close cover, a locking screw and a check ring; one side of the motor is provided with the motor belt wheel; the rotating hoop belt wheel is arranged above the motor belt wheel; the belt is sleeved on the periphery of the motor belt wheel and the rotating hoop belt wheel; the bearing stand is arranged on one side of the rotating hoop belt wheel; two ends of the rotating hoop are provided with the bearing stand; the middle part of the rotating hoop is horizontally provided with at least one mounting hole, and the middle part of the lateral surface of the rotating hoop is provided with at least one observation window; and the mounting hole is provided with a straightening roll component. The mounting angle of the straightening roll can be conveniently adjusted by the dental plate, the rolling reduction of the straightening roll can be conveniently adjusted by the adjusting screw mandril, and the locking bolt is locked after the position of the straightening roll is adjusted. When working, the straightening roll rotates along with the rotating hoop at a high speed and also rotates around the axes of the straightening roll.

Description

technical field [0001] The invention relates to a straightening machine device and a straightening method thereof, in particular to a straightening device and a straightening method of a rotary hoop skewed roller type straightening and cutting machine. Background technique [0002] At present, most of the steel bar straightening devices in the prior art adopt the straightening method of the rotary hoop pressing block type. The hoop rotates together with the pressure block to straighten the steel bars; this straightening structure will cause too much damage to the steel bars to be straightened, and the straightening efficiency is low, and it is not suitable for straightening large-diameter steel bars (above φ12); there are also The individual straightening device adopts the straightening structure of the rotary hoop roller type. It fixes the roller frame on the hoop and installs the straightening roller inside it. This structure can adjust the angle and reduction of the strai...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the steel bar straightening devices in the prior art adopt the straightening method of the rotary hoop pressing block type, and its structural form is: several movable pressing blocks are installed in the rotating hoop, and the pressing amount of the pressing blocks can be adjusted by adjusting screws; The hoop rotates together with the pressing block to straighten the steel bars; this straightening structure will cause too much damage to the steel bars to be straightened, and the straightening efficiency is low, and it is not suitable for straightening large-diameter steel bars (above φ12); there are also The individual straightening device adopts the straightening structure of the rotary hoop roller type. It fixes the roller frame on the hoop, and the straightening roller is installed in it. This structure can adjust the angle and reduction of the straightening roller It is inconvenient, and the structural size is large, and the moment of inertia is also large when the hoop rotates, which will adversely affect the operation and life of the equipment
