Abstract
A cold-rolling pipe mill for machining an internally-rounded square pipe comprises a working rack and a mill roll assembly, wherein the working rack is arranged on a base, and the mill roll assembly is arranged in the working rack. The mill roll assembly comprises a roll base, an upper mill roll set and a lower mill roll set. The upper mill roll set comprises an upper mill roll and an upper roll shaft. The lower mill roll set comprises a lower mill roll and a lower roll shaft. The roll surface of the junction between the upper mill roll and the lower mill roll is provided with a square linear outline hole. A central spindle which is matched with an inner hole of the square pipe is arranged in the outline hole. One end of the upper roll shaft and one end of the lower roll shaft are respectively provided with a synchronous gear transmission mechanism. The working rack is provided with a crank link mechanism and a double-rocker mechanism. In the rolling process, the crank link mechanism is utilized to drive the working rack to reciprocate so that a pipe billet can be pushed forward, the upper mill roll and the lower mill roll rotate periodically by utilizing the interaction between the synchronous gear transmission mechanisms and the double-rocker mechanism, and meanwhile transverse rolling can be performed on the pipe billet by moving the roll base between the upper mill roll and the lower mill roll. In this way, repeatedly, rolling of the whole pipe billet is completed.
Description
Technical field
The present invention relates to a kind of metal pipe material cold working equipment, particularly a kind of processing square-outside and round-inside tubing cold pilger mill.
Background technology
At present, the cold working of metal pipe material is produced and is mostly adopted drawbench to draw, the especially wall thickness of pipe of the shape and size of the production tube of this manufacture method to cold drawn forming, often be difficult to the accuracy class that reaches higher, and for the tubing manufacture of square-outside and round-inside that has particular demands, existing especially cannot disposable drawing moulding, all need to adopt multiple tracks drawing and intermediate heat-treatment, the operation such as take the lead can realize, so both caused complex process, make again manufacturing cost improve, be difficult to meet specific user's demand.
Summary of the invention
Technical problem to be solved by this invention is that the square-outside and round-inside tubing cold pilger mill that a kind of Product Precision that has the moulding of continuity time processing and produce is higher is provided.
Technical scheme of the present invention is: a kind of processing square-outside and round-inside tubing cold pilger mill, comprise and be arranged at the work housing on support and be arranged at the roller assembly in work housing, described roller assembly comprises and is the roller seat being equipped with in frame, topping roll group and bottom roll group, described topping roll group comprises topping roll, upper roll shaft, bottom roll group comprises bottom roll group, lower roller shaft, upper, the roll surface of bottom roll joint portion is provided with the linear profile hole being square, in profiled orifice, be provided with the mandrel suitable with inner hole of square, upper, lower roller shaft one end is respectively equipped with the synchromesh gear transmission mechanism that is interlaced arrangement, one end at work housing is provided with toggle, the other end at work housing is provided with double rocker mechanism.
The present invention is owing to having adopted the synchromesh gear transmission mechanism arranging respectively in upper and lower roll shaft one end, be combined in toggle and double rocker mechanism that work housing and roller seat arrange, when rolling, utilize toggle to drive the reciprocating pipe that makes of work housing to push ahead, utilize synchromesh gear transmission mechanism and double rocker mechanism to cooperatively interact, make top and bottom rolls in making periodic rotary, between two rollers, realize the horizontal calendering to pipe by mobile roller seat, go round and begin again like this, complete the rolling of whole pipe.
