Description
Technical field
The utility model relates to a kind of machining equipment, relates in particular to a kind of positioner that is used for seamless steel pipe blank round steel production equipment.
Background technology
Seamless steel pipe is common metallurgical metallic article, and in the seamless steel tube production, hot-puncturing process processing is main production process, promptly adopts hot-rolling perforation machine to the pipe perforation cogging after heating, and the metal pipe is processed into the hot rolling hollow forging.
It is the phase I that the seamless steel pipe hot-rolling perforation is produced that pipe is prepared, and comprises surely cutting, peeling, deciding operation such as core; Decide core and be exactly through cut surely, metal round steel end face processing certain depth after the peeling and the centre bore of diameter, the diameter of centre bore and the degree of depth are complementary according to required perforation specification requirement, purpose is when boring a hole under the condition of high temperature of round steel heating back, perforating head is played correct centering and guide effect, prevent to be offset because of the perforation axial line that the top skew causes, and then the axiality of the inside and outside circle of influence perforation back hollow forging.
Hot-puncturing process is the critical process of seamless steel tube production, and it is to adopt the carbide alloy top, under mechanokinetic drives, aims at the centre bore of heating back round steel, carries out cephalocaudal axial drilling operation, round steel is processed into hot rolled seamless steel tube, i.e. hollow forging.With regard to perforation process, the inside and outside circle concentricity of perforation back hollow forging is a leading indicator of weighing the perforation quality, will cause follow-up cold deformation processing difficulties in case surpass the error that allows, and can only scrap when serious.Therefore improving round steel centre bore machining accuracy, is the main guarantee that improves hollow forging perforation quality.
Decide the core machine and be to be used for the special equipment in the round steel blank end face machining center hole before the hot-puncturing process, by transmission mechanism, clamp mechanism, award material mechanism, lathe bed mechanism, feed mechanism, turnover bin, hydraulic system, electrical system, cutting tool etc. and form; Wherein clamp mechanism is made up of parts such as hydraulic cylinder, supporting base, clamp, fixed blocks, is used for round steel and decides the clamping of core processing round steel with fixing.Its course of work is: at first cutting tool is installed in the main shaft female cone hole of transmission mechanism, round steel with core processing undetermined is emitted on the tilting feeding rack of deciding the core machine subsequently, round steel rolls to the lathe bed direction under the gravity effect, stirs one by one on " V " type carriage that enters lathe bed mechanism by awarding material mechanism; The operation principle of clamp mechanism is shown in Fig. 1 a and Fig. 1 b, hydraulic cylinder piston rod stretches out, " V " type clamp 161 promotion round steel 17 that are installed on the piston rod move until the 162 back clampings of " V " type fixed block, wherein the size of the clamping force of vertical round steel radial direction is by the output pressure decision of hydraulic system, and can be adjusted by the overflow valve of hydraulic system, to satisfy the clamping demand of different size round steel, two " V " type fixed blocks 162 are mounted and fixed on lathe bed and stock shelf junction respectively, purpose is the head and the tail two parts that can prop up round steel respectively, improves the effect that is fixedly clamped.Motor start-up, power output to transmission mechanism and drive the drill bit rotation along the feeding of P direction.According to the object localization principle, this clamp mechanism has limited the free degree of round steel 17 six directions, realized location fully, wherein three " V " type bodies being made up of clamp 161, fixed block 162 have been eliminated the moving horizontally and rotatablely moving of X, z axis direction of round steel, clamping force under the hydraulic action has been eliminated round steel Y-axis line direction, be moving horizontally and rotatablely moving of round steel axial direction, the insufficient clamping force that in a single day event is provided by hydraulic cylinder, moving horizontally and rotatablely moving of round steel Y-axis line direction just can not get effective restriction, i.e. the locate failure of two frees degree.
Therefore there is following deficiency in present clamp mechanism:
(1) free degree of the round steel Y direction pressure of hydraulic system output that places one's entire reliance upon, in case hydraulic coupling is not enough or take place unusual, the positioning deficiency that will cause the free degree of round steel Y direction causes round steel clamping and positioning effect deficiency, and is light then cause round steel under the effect of drill bit, in axial direction retreat, heavy then round steel rotates under drill bit smear metal revolving force drives, and causes the stalk cutter, has both caused tool damage, cause the round steel centre bore to lose efficacy again, easily cause equipment fault and personnel's injury when serious.
(2) though round steel decide before the core through cut surely, peeling processing, but after the end face sawing without smooth smear metal, there is horizontal cut channel, this cut channel has influence on the centering effect that drill bit adds man-hour, initial boring adds the centering correction by force of drill bit in man-hour, so the clamping force that round steel is added clamp mechanism is had relatively high expectations, and in a single day clamping force can not satisfy the demand, easily cause centre bore to add the off-centre in man-hour, long line phenomenon, the core crudy is decided in influence.
(3) for large-size round steel, the rated operating pressure of deciding the core machine hydraulic system can't satisfy the demand that round steel clamps, cause normal pressure be not enough in the fixedly round steel processing shake, rock, off-centre, long line phenomenon appear in the centre bore that makes round steel process.
(4) existing clamp mechanism too relies on the clamping force of hydraulic system output, cause Hydraulic Elements bearing loads such as hydraulic cylinder bigger than normal, seal spoilage height, influence service life, fault routine is many, fault is frequent when especially producing large-size round steel, has influence on the running quality of equipment to a certain extent.
