Description

The turning attachment that is used for the processing of jaw body inner arc surface
Technical field
The utility model relates to a kind of machined into equipment, particularly, the utility model relates to a kind of lathe special tooling anchor clamps that are used for high-speed cold Pilger mill that metallurgy, mechanical industry steel pipe's production uses with the jaw body machine tooling, and described anchor clamps are specially adapted to produce the jaw body inner arc surface processing of the high-speed cold Pilger mill of steel pipe such as seamless steel pipe.
Background technology
Steel pipes such as seamless steel pipe are common metallurgical metallic articles, its production procedure is: pipe production (steel-making, steel rolling), steel tube blank (metal round steel), pipe are prepared (length cutting, surperficial peeling, spotting), circular steel are machined to be qualified pipe; Hollow forging is produced (hot-rolling perforation machine is processed into the hot rolling hollow forging to high temperature pipe perforation cogging with the metal pipe); Then, according to the specification requirement of production tube, adopt corresponding cold deformation (cold rolling, cold-drawn) processing technology, operation in accordance with regulations requires to carry out cold deformation processing, hollow forging production is become the steel pipes such as finished product seamless steel pipe of requirement up to specification; After the steel pipes such as finished product seamless steel pipe that are up to the standards are cut surely, spray printing, packing.
In the production of steel pipes such as seamless steel pipe, the cold deformation processing is main production process.And cold rolling production big because of deflection, be easy to control, rolling accuracy height, advantage such as speed is fast, output is big, become the cold deformation processing mode of extensive employing.
At present, what be used for the cold roller and deformed processing of steel pipe such as seamless steel pipe is cold pilger mill, and cold pilger mill is divided into two kinds of two roller cold-rolling pilger mills and multiple roll cold-rolling pilger mills; Two roller cold-rolling pilger mills are divided into annular distance formula and two kinds of cold pilger mills of half cellular type according to the difference of mode of texturing (instrument).Advantages such as annular distance formula cold pilger mill is long because of the frame impulse stroke, deformed region is long, mill speed is fast, roll-force is big are widely used as steel pipe rolling production equipments such as high-accuracy weldless steel tubes.
The SKW-75 high-speed cold mill is the steel pipe cold-rolling equipments such as seamless steel pipe that German Mannesmann Mil company produces.This equipment by main drive gear, rolling mechanism, feed mechanism, slew gear, hydraulic mechanism, pneumatic mechanism, lubricating structure, grant material mechanism, cooling body, electric control system etc. and partly form, be used for steel pipe's production such as rolling φ 19~φ 57mm high-accuracy weldless steel tube.The slew gear of SKW-75 high-speed cold mill is made up of parts such as plug chuck assembly, inlet chuck assembly, outlet chuck assembly, power transmission shafts, be used in the operation of rolling, clamp and drive the specification requirement of plug, pipe, production tube according to feeding and corner, rotate around same rolling centerline, meet quality, required precision with the circularity that guarantees steel pipes such as seamless steel pipe.
In high speed cold-rolling mills such as SKW-75, the plug chuck assembly is to clamp and drive plug, and the inlet chuck assembly is to clamp and drive pipe, and the outlet chuck assembly is to clamp and drive rolling back production tube.The inlet chuck assembly is identical with outlet chuck assembly structure, forms by parts such as hydraulic cylinder, support, shift fork, main shaft, gear-box, claw, locating rings.In order to guarantee that pipe and production tube are in Rolling Production, should overlap, not depart from rolling centerline, guarantee again under clamping force drives, to rotate, therefore having relatively high expectations claw, for the steel pipes such as seamless steel pipe of different rolling specs, select the claw of corresponding specification for use.
On the other hand, claw is according to purposes, be divided into inlet claw (being used to clamp pipe), outlet claw (being used to clamp production tube) two kinds, it is that copper is (soft than steel copperly that material is, be difficult for steel pipe outer round surface such as scratch seamless steel pipe), be installed in respectively on the main shaft of inlet chuck assembly and outlet chuck assembly.One secondary claw is made up of three jaw body and three slide plates, and hexagonal flat-bed machine screw was fixed on the jaw body in slide plate adopted, and the prior installation forming of claw uses in groups.
Jaw body is the right-angled trapezium body (Fig. 4) of a band inner arc surface, and inner arc surface is its steel pipe clamping face, is processed with three installation screwed holes on inclined-plane the installed surface of jaw body bearing (promptly with), and three screwed hole center lines are vertical with the inclined-plane; Inclined-plane and end face (left surface is promptly towards the clamp body side) angle is generally 105 °, and inclined-plane and baseplane (right flank, i.e. Tool advance side) angle is usually at 75 °.In addition, end face of described jaw body (towards the clamp body side) and inner arc surface junction smooth connection of fillet are certain angle between baseplane (Tool advance side) and the inner arc surface, are convenient to steel pipes such as seamless steel pipe and enter, and play the guiding role.The inner arc surface of jaw body is used to clamp steel pipe (pipe, production tube) outer circumference surfaces such as seamless steel pipe, according to different specifications, is processed with corresponding circular arc.
In above-mentioned occasion, three jaw body constitute a complete circular hole, and steel pipes such as seamless steel pipe (pipe, production tube) outer circumference surface is contained.Jaw body is after use, its inner arc surface can produce wearing and tearing, at this moment, usually, angle (gradient) that can be by the inclined-plane is adjusted, compensation under the effect of hydraulic cylinder automatically, after wear extent overshoot scope, just must change, guarantee that the malalignment of chuck assembly and rolling centerline meets specification requirement.
Because the inner arc surface of jaw body is to be used for chuck assembly under the prerequisite that guarantees rolling centerline, clamp steel pipes such as seamless steel pipe, therefore the requirement on machining accuracy height generally adopts machined metal cutting form processing inner arc surface, i.e. planer, milling machine, drilling machine processing; And the problem that the processing mode of present following jaw body inner arc surface exists is:
1) planer processing: jaw body is vertically fixed on the flat-nose pliers one by one, and flat-nose pliers is fixed on the workbench, adopts the circular arc planing tool, digs inner arc surface on jaw body.Because this method, circular arc planing tool reconditioning difficult forming needs to be ready to corresponding planing tool according to different size in advance, and needs reconditioning again after the planing tool wearing and tearing, during the consumption expenses of labour.Inner arc surface can't be directly measured in planer processing simultaneously, can only adopt comparison method, by lining bar, gauge block measurement, thus, causes the circularity machining accuracy of inner arc surface relatively low; The production efficiency of single-piece work is low.
2) milling machine processing, this method system is placed on jaw body on the workbench by group, fixes according to the scribing position on platform in advance, adopts that special-purpose milling cutter is top-down vertically to be processed.According to this method, standard milling cutter curtailment 100mm need select the extended type milling cutter for use, therefore need be ready to the extended type milling cutter of corresponding size according to different specifications.Behind the cutter wear, can not reconditioning, so that processing consumes is big, expense is high; Simultaneously, because processing in groups, to jaw body clamping positioning requirements height, it is consuming time to take a lot of work, and production efficiency is low; In case produce skew in the clamping process, will cause inner arc surface machining deviation to occur and scrap.
3) drilling machine processing according to this method, is that jaw body is placed on the workbench by group, fixes according to prior scribing position on platform, and employing standard spiral bit is top-down vertically to be processed.According to different specifications, be ready to the drill bit of corresponding size, behind the bit wear, can reuse (reconditioning just can not be used to the not enough 105mm of drill bit fried dough twist segment length) through after the emery wheel reconditioning, so processing cost is less.Yet similar to milling machine processing, this method needs processing in groups because of jaw body, and to jaw body clamping positioning requirements height, it is consuming time to take a lot of work, and production efficiency is low; In case produce skew in the clamping process, also can cause inner arc surface machining deviation to occur and scrap.
Obviously as seen.With regard to three kinds of machine tooling modes of present high-speed cold Pilger mill jaw body, all there is certain deficiency, have influence on the machining accuracy and the production efficiency of jaw body.
Yet, if for the machining of jaw body inner arc surface, and buy a specialized nc machine tool specially neither be practical, reduce cost and effective way.Utilize the advantage (but reconditioning, precision height) of drill bit processing, on engine lathe, process, can guarantee machining accuracy, can improve working (machining) efficiency again, but because of lathe is that main shaft is parallel to the ground, jaw body is machine on the clamping in groups, and together processing could guarantee that circularity meets specification requirement., be necessary for this reason, adopt the special tooling anchor clamps to address this problem according to the machined into characteristics.
