Embodiment Construction
[0017] Description with reference to the accompanying drawings.
[0018] The buffer device of this embodiment is used in a pneumatic borer driven by compressed air. The magazine hanger 7, magazine 9 and buffer head 6 of the borer at both ends of the steel pipe have the same structure and can work interchangeably, namely The magazine hanger 7 etc. of the right end is not only the receiving end of the bore bullet, but also the launch end of the bore bomb, and the magazine hanger 7 etc. of the left end is both the launch end of the bore bullet and the receiving end of the bore bullet. When the magazine hanger 7 etc. on the right side is the receiving end of the diameter bomb 11, the magazine hanger 7 etc. on the left side is the launching end of the diameter bullet 11, when the magazine hanger 7 etc. on the right side is the During the launch end of diameter bullet 11, magazine hanger 7 etc. on the left side are the receiving ends of diameter bullet 11. The figure only shows the...

The invention relates to a drift bullet buffering device of a pneumatic drifter, and belongs to equipment for detecting inner diameter and straightness of steel pipes. The drift bullet buffering device is used for drifting of steel pipes. A buffer head of the drift bullet buffering device is positioned at the back of a magazine, and an exhaust port is arranged on the inner wall of the front of the magazine. When the front end of a drift bullet exceeds the exhaust port in running, a semi-closed cavity is formed between the drift bullet and a magazine hanger inner cavity, then the drift bullet is decelerated greatly, momentum is reduced, and the technical problem that existing pneumatic drifter buffering devices are high in destructive effect and short in service lives is solved. The drift bullet buffering device is simple in structure and reliable in use. By cooperation of a detecting reset spring with low elasticity coefficient and a buffering spring with high elasticity coefficient, the drift bullet buffering device is applicable to reliably and accurately buffering, receiving and realizing in-place detection of drift bullets with remarkable difference between diameter and momentum.
Description
technical field [0001] The invention relates to testing equipment for the inner diameter and straightness of steel pipes, in particular to a bore spring buffer device for a pneumatic bore machine. Background technique [0002] Under the action of gas pressure, the bore bullet of the pneumatic calibrating machine is used for the diameter of steel pipes with a length of several meters to more than ten meters and an outer diameter of tens of millimeters to hundreds of millimeters. The bullets make the bullet receiving end of the pneumatic bore machine bear a great impact. China Invention Patent Authorization Announcement No. CN 10042616 C "Pneumatic Boring Machine and Boring Method" and "Hydraulic and Pneumatic" 2007 No. 3 "Design and Application of Pneumatic Steel Pipe Boring Machine" discloses that the pneumatic bobbing machine adopts cylinder buffering device, the latter also adds springs on both sides of the baffle plate of the buffer device cylinder. The common shortcom...
