Description
Technical field
The invention belongs to metal pipe material processing equipment technical field, be specifically related to a kind of slew gear of cold pilger mill.
Background technology
Cold pilger mill widely uses in tubing processing industry, and in Chinese patent literature, is no lack of the technical scheme being seen in about cold pilger mill, omit the continuous feeder of a kind of two cold mill pipe as disclosed in utility model patent Granted publication CN201223884Y to exemplify, the achievement part of this scheme has solved the technical problem that the double-roller cold pilger mill that first has can not continuous operation, because, double-roller cold pilger mill in prior art is after having sent to, because feeding trolley can only withstand pipe rear end, the necessary rollback of feeding trolley is to home position (reset), be housed to next root pipe, the pipe that penetrates plug enters feeding trolley, feeding trolley starts to send to after withstanding pipe, so there is the auxiliary times such as one section of feeding trolley rollback and handling clamping, cause this cold pilger mill can not continuous operation, therefore this patent scheme can be increased work efficiency undoubtedly.And for example: the revolution feed mechanism of a kind of cold pilger mill that CN12788915Y recommends has the alleged technique effect of Instructions Page 2 14th ~ 19 row of this patent.For another example: the cold pilger mill that CN2621094Y introduces send slew gear to, this scheme is arranged between the head and feeding lathe bed of cold pilger mill sending slew gear to, jackshaft system and the 2-level reducer of having cancelled the cold pilger mill in prior art, significantly reduce the floor space of cold pilger mill.
Except the above-mentioned technical scheme exemplifying, also just like CN2385817Y (feed mechanism of cold pilger mill), CN2386900Y (pipe mill send to slew gear), CN2656036Y (cold pilger mill is sent slew gear to), CN201067762Y(electrical control is sent to and rotating novel pipe mill), the steel pipe rotary feeding mechanism of CN201470679U(pipe mill), the revolution feed mechanism of a CN201543661U(double-roller cold pilger mill) and CN201592194U (hydraulic revolving feed device of cold pilger mill), etc.
Feed mechanism and slew gear are acknowledged as the key mechanism of cold pilger mill, the technical scheme of above-mentioned Introduction of Literatures has mainly been concentrated this two great institutions, and in prior art by feed mechanism and the same casing of slew gear set (being called revolution feeding box), the advantage of this structure is that set degree is high and can reduce taking space again, but, process and assemble precision is had to extremely harsh requirement, once especially feed mechanism breaks down or slew gear breaks down and can produce the phenomenon bring disaster to each other (involving), causes trouble to inspection and maintenance.
" slew gear of cold pilger mill " that invention patent mandate notification number CN102059252B recommends separates slew gear and feed mechanism and has an independently structural system of one's own, and can implement automatic pine to the claw on chuck opens or clamps, both can alleviate operator's working strength, can improve again the operating efficiency of chuck and guarantee that one group of claw has good action effect to plug, but complicated integral structure and volume large be the shortcoming of this patent.
