Description
Technical Field
The utility model relates to a frock, especially a pneumatic transmission pipeline shape return bend frock of preapring for an unfavorable turn of events.
Background
At present, the pipe bending technology is widely applied to pneumatic transmission pipelines, and due to the particularity of media of sampling pipelines (the media are sampling bottles) and the precision requirement of pipe bending is quite high, deformation control in the pipe bending process is a main index for good and bad product quality in the pipe bending process. The circular arc part of the pipe bending in the bending process can be gradually flattened, and the inner wall of the pipe bending bears great deformation stress, so that the problem that the section of a straight line section near the pipe needing to be bent is deformed at present is easily caused, and no effective measure is provided for solving the problem.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem that the straightway cross-section that links to each other with crooked position on the prior art tubular product takes place deformation easily, the utility model provides a shape return bend frock of preapring for an unfavorable turn of events.
The technical proposal of the utility model is that the anti-deformation pipe bending tool for the pneumatic transmission pipeline comprises a flexible core shaft, a sleeve, a gasket and a nut, the flexible mandrel is sleeved with an elastic expansion head, a round-head expansion ring and a sleeve, the elastic expansion head is cylindrical in external shape, a through hole I matched with the flexible mandrel is arranged in the elastic expansion head, the through hole I is divided into an upper section of the through hole I and a lower section of the through hole I, the upper section of the through hole I is in an inverted cone shape, the lower section of the through hole I is in a cylindrical shape, a longitudinal vertical groove is formed in the end face of the upper section of the elastic expansion head through hole I, a round hole is formed in the upper end face of the lower section of the through hole I, the vertical groove extends into the round hole, and is communicated with the bottom of the vertical groove, the round head expansion ring is in a round cake shape, a through hole II matched with the flexible mandrel is arranged in the middle, the flexible core shaft is cylindrical, threads are arranged on the outer side of the upper section of the flexible core shaft, and a protruding fixing part is arranged at the bottom end of the lower section of the flexible core shaft.
Further, the maximum diameter of the through hole is D2, the minimum diameter is D3, and D3 is D2 of 3/5 when the elastic expansion head is not expanded.
Furthermore, the center of the vertical groove and the center of the round hole are on the same straight line.
Furthermore, 4 vertical grooves are uniformly distributed on the upper section of the elastic expansion head, and 4 corresponding round holes are uniformly distributed in the 4 vertical grooves.
Further, the fixing part is cylindrical in shape.
The beneficial effects of the utility model are that, through the use of this frock, the effectual problem of avoiding the return bend in-process deformation.
