Description
Technical field
The utility model relates to steel pipe heat treatment equipment, specifically a kind of flexible servo-actuated clamping-rotating device.
Background technology
In the quenching apparatus of metallurgical industry weldless steel tube, device for clamping and rotating is one of visual plant.Existing device for clamping and rotating includes base, base is equipped with the two groups of rotation support rollers be arranged side by side, be provided with a swing arm, the lower end of swing arm is provided with fixing driving mechanism, the upper end of swing arm is provided with pinch roller, is just forming in rigidity the top of workpiece and is pressing clamping mode.This device for clamping and rotating Problems existing is: 1, steel pipe is because producing certain bending in heat treatment process, thus causes mechanisms grip unstable; 2, because " upper pressure " mode locally can block outer pouring heat-eliminating medium, cause in the outer pouring process of thermal treatment, making heat-eliminating medium uniform fold cause at steel pipe upper surface steel pipe to produce deformation and uneven microstructure, affect quality product; 3, mode of " rigidity being pressed " can not self-adaptation to the distortion in steel tube quench, easily causes steel tube surface to damage and depressed deformation; Be unfavorable for thin-wall steel tube especially; 4, when wall thickness steel tube heat treatment quenching process, steel pipe is under different immersed depth, and upper pressure device is difficult to take into account the balance compressed with clamping force, and mechanism is huge, adjustment difficulty.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned four aspect problems that will solve the existence of existing Steel Pipe Heat process device for clamping and rotating, provides a kind of flexible servo-actuated clamping-rotating device.
Concrete scheme of the present utility model is: improve for existing device for clamping and rotating steel tube, it has base, on base, left and right is arranged side by side with two groups of rotation wheel holding mechanisms, it is characterized in that: on base both sides, left and right swing arm is housed, the middle part of two swing arms is equipped with rotating shaft and base and is formed and be rotationally connected, pinch roller is equipped with in the upper end of two swing arms, upper end level exceedes rotation support roller, and compress forming above the side of workpiece under impaction state, the lower end of two swing arms is rotationally connected by bearing pin respectively at the rear and front end with a transfer bar mechanism.
Pinch roller on two swing arms described in the utility model, under impaction state be more than the medullary ray to workpiece 30 ~ 70 ° side above form compress, with ensure compress reliable and stable.
Pinch roller on two swing arms described in the utility model, under impaction state be more than the medullary ray to workpiece 60 ° side above form compress, to realize optimal compression state.
Base described in the utility model is provided with craniocaudal axis bearing; Described two groups rotate wheel holding mechanism, include two main shafts, two main shafts are contained in craniocaudal axis bearing side by side, the outer end that bearing support is extended in one end of two main shafts is provided with power wheel, every root main shaft is provided with former and later two support rollers, support roller front-back staggered on two main shafts is arranged, to adapt to the steel pipe support to different size diameter.
Transfer bar mechanism described in the utility model is the below being positioned at base, has space that is flexible and upper and lower displacement.
Transfer bar mechanism described in the utility model is oil cylinder or cylinder or push-rod electric machine.
Support to form with the bar that swings respectively about base described in the utility model is provided with and be rotationally connected.
The utility model has carried out compressing above side to steel pipe owing to have employed two swing arms in left and right, adapts to all standing of heat treatment process China and foreign countries trickle, can not block water and drench, meet the uniform fold of the outer trickle of steel pipe upper surface in heat treatment process; Have employed a transfer bar mechanism simultaneously and connect two swing arms, can realize flexible servo-actuated, the self-adaptation bending to steel pipe trace.
The utility model has the following advantages: 1. immerse in thermal treatment process at middle wall thickness tube, in change in depth situation, mechanism is small and exquisite, trackability good, takes into account to compress to balance with clamping force; 2. pair flexibility of steel pipe self-adaptation is strong, can clamp the steel pipe that distortion is larger; 3. in middle thin-walled tube thermal treatment process, outer trickle all standing; Without blocking phenomenon, ensure that the outer trickle uniform fold of steel pipe upper surface in Steel Tube Heat Treatment Process; 4. be applicable to outer pouring+interior pressure spray process: when steel pipe is delivered to rotation support roller by charging equipment, the clamping steel pipe of the flexible servo-actuated device for clamping and rotating of steel pipe; Rotate support roller and drive steel pipe low speed rotation; Then according to thermal treatment process requirement, pipe diameter water spray and outer pouring heat-treatment quenching; Because clamping device is in steel pipe sandwich; Therefore trickle does not exist and blocks phenomenon on the upside of steel pipe, thus Steel Pipe Heat process avoids outer trickle evenly to cause heat treated defect; 5. be applicable to immersion+interior pressure spray process: when steel pipe is delivered to rotation support roller by charging equipment, the clamping steel pipe of the servo-actuated clamping device of steel pipe; Rotate support roller and drive steel pipe low speed rotation; Then according to thermal treatment process requirement, pipe diameter water spray and immersion heat-treatment quenching; Because clamping device clamps on steel pipe both sides; And clamping device fixes with pedestal with support roller, can be servo-actuated along with immersed depth difference; Clamping device clamping can keep pressure constant.
