Problems solved by technology

However, there is no corresponding technical revelation in the published patents and non-patent literature, and there is no report of success in the industry.
[0005] As far as the rotary mechanism for clamping the mandrel and turning the mandrel is concerned, the disclosed technologies are almost all operating the jaws on the chuck in a manual manner, or releasing the jaws from clamping the mandrel. , or release the jaws to the mandrel, so the operator’s operation intensity is high, the operation time is lengthy and it is difficult to ensure the clamping effect of a set of jaws on the chuck (usually three, distributed at 120°) on the mandrel

Embodiment Construction

[0019] In order to make the examiners of the patent office, especially the public, further understand the technical essence of the present invention, the applicant will illustrate with the examples given below, but the examples are not limitations to the scheme of the present invention. Any changes made only in form but not in substance shall be regarded as the scope of the technical solution of the present invention and shall be protected.

[0020] please see figure 1 , provides the mounting support seat 1 of the rotary mechanism of the cold-rolled pipe mill used alone, the meaning of the so-called used alone means: when the present invention is configured on the complete set of cold-rolled pipe mill, there is no existing technology with feeding mechanism 7( figure 2 Shown) the situation of sharing a support seat 1. The installation support base 1 has a fixed plate 11, front and rear wall panels 12, 13, a left wall panel 14, a right wall panel 15, a first box body adjustme...

Abstract

The invention relates to a swing mechanism of a cold-rolling pipe mill, and belongs to the technical field of metal pipe processing machinery. The swing mechanism comprises a mounting support base, a transmission case which is arranged on the mounting support base and is provided with a cover, a power transmission device which is arranged on the transmission case and comprises a power input shaft, a transition shaft and a power output shaft, a chuck which is arranged on the power output shaft in a sliding way, and a set of jack catches which are arranged on the chunk in a sliding way. The swing mechanism is characterized by further comprising a chunk actuating device which is used to drive the chunk to slide on the power output shaft left and right and further change the position of the set of the jack catches which are arranged on the chunk in a sliding way, wherein the chunk actuating device is fixed on the cover of the transmission box and is connected with the chunk. The swing mechanism has the advantage of fast operation speed and good action consistency of the jack catches, and can lighten the working strength of operators.

Description

technical field [0001] The invention belongs to the technical field of metal pipe material processing machinery, and in particular relates to a rotary mechanism of a cold-rolled pipe mill. Background technique [0002] Cold-rolled pipe mills are widely used in the pipe processing industry, and there is no shortage of technical solutions related to cold-rolled pipe mills in Chinese patent documents. For example, a two-roller cold-rolled pipe mill disclosed in the utility model patent authorization announcement number CN201223884Y Rolling mill tube billet continuous feeding device, the achievements of this program have solved the technical problem that the previous two-roll cold-rolled tube mill cannot work continuously, because, when the two-roll cold-rolled tube mill in the prior art is fed Finally, since the feeding trolley can only withstand the rear end of the tube billet, the feeding trolley must be returned to the original position (reset), and the next tube blank to be...
