Abstract
A cold-rolling pipe mill for machining a rectangular pipe comprises an upper mill roll set and a lower mill roll set. The upper mill roll set comprises an upper mill roll and an upper mill roll shaft. The lower mill roll set comprises a lower mill roll and a lower mill roll shaft. The junction between the upper mill roll and the low mill roll forms a rectangular outline hole. A central spindle which is matched with a rectangular pipe hole is arranged in the outline hole. The two ends of upper mill roll shaft and the two ends of the lower mill roll shaft are respectively provided with synchronous gear transmission mechanisms and transverse cylinders, wherein the synchronous gear transmission mechanisms and the transverse cylinders are arranged in a staggered mode. A rack is provided with a crank link mechanism which can drive the rack to reciprocate. As the synchronous gear transmission mechanisms, the transverse cylinders and the crank link mechanism are adopted, wherein the two ends of upper mill roll shaft and the two ends of the lower mill roll shaft are respectively provided with the synchronous gear transmission mechanisms and the transverse cylinders, and the crank link mechanism can drive the rack to reciprocate; in the rolling process, a pipe billet is pushed forward by the utilization of the reciprocation of the rack, the upper mill roll and the lower mill roll rotate periodically by the utilization of the synchronous gear transmission mechanisms and the transverse cylinders, and meanwhile transverse rolling can be performed on the pipe billet between the two mill rolls through the transverse cylinders. Repeatedly, rolling of the whole pipe billet is completed.
Description
Technical field
The present invention relates to a kind of tubing process equipment, particularly a kind of processing rectangle pipe material double-roller cold pilger mill.
Background technology
It is to adopt drawbench to draw that the cold working of traditional rectangular tubing is produced, the shape and size of the production tube of cold drawn forming, especially the wall thickness of pipe, often be difficult to the accuracy class that reaches higher, more difficult satisfied a part of specific user's use, in addition, for the relatively large rectangular tube of length-width ratio, existing cannot a drawing moulding, and multi-pass draws to open up to pull out also needs to increase intermediate heat-treatment and the operation of taking the lead, and then has improved the deficiencies such as production cost.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiency of above-mentioned existence, provide a kind of machining accuracy that improves rectangle pipe material, the processing rectangle pipe material double-roller cold pilger mill that can different size rectangle pipe material be implemented processing continuously and can effectively be reduced production costs simultaneously.
Technical scheme of the present invention is: a kind of cold pilger mill of processing rectangle pipe material, comprise the frame being arranged on support, be arranged at topping roll group and bottom roll group in frame, described topping roll group comprises topping roll, topping roll axle, described bottom roll group comprises bottom roll, lower roller shaft, upper, bottom roll joint portion is formed with rectangular profiled orifice, in profiled orifice, be provided with the mandrel suitable with rectangle pore, upper, lower roller shaft two ends are respectively equipped with the synchromesh gear transmission mechanism and the sideslip oil cylinder that are interlaced arrangement, in frame, be provided with the toggle that can drive support body to do horizontal reciprocating movement.
The present invention is owing to having adopted the synchromesh gear transmission mechanism that dislocation is arranged that is arranging respectively at upper and lower roll shaft two ends, sideslip oil cylinder mechanism and can drive frame to do the toggle of horizontal reciprocating movement, when rolling, utilize the reciprocating motion of frame that pipe is pushed ahead, utilize synchromesh gear transmission mechanism and sideslip oil cylinder mechanism, make upper and lower roll in making periodic rotary, between two rollers, realize the horizontal calendering to pipe by sideslip oil cylinder, go round and begin again, complete the rolling of whole pipe.
