Description

Machine head structure of double-piston buckling press for displacement-free jumping stand die holder

Technical Field

The utility model relates to a withhold the press field, especially relate to a no displacement diving tower die holder double piston withholds press head structure, be applicable to fluid line connecting piece assembly withhold preparation (hydraulic pressure rubber tube, vehicle air conditioner pipe etc.) and non-fluid metal subassembly withhold the various types of hydraulic power withhold machine that the pressure formula connection processing field used (including draw machine, lock pipe machine, pressure pipe machine and tapered end machine etc.).

Background

At present, in a crimping machine which is widely used for manufacturing various connecting component assemblies, a crimping machine head structure which realizes main functions can be divided into the following two main forms: one is an annular horizontal type buckling press (see figure 1) which buckles the pipe body with the axis consistent with the motion direction of a power source; one is an ultra-thin vertical type crimping machine (see fig. 2) in which the axis of the crimping pipe body is perpendicular to the motion direction of the power source. Compared with an ultrathin vertical buckling press in which the buckling pipe body is perpendicular to the power source direction, the annular horizontal buckling press in which the buckling pipe body is consistent with the power source direction has good and bad performances due to differences of the force taking direction, the buckling pressure conversion mode and the efficiency.

Under the same buckling range or the same buckling force, the annular horizontal buckling and pressing machine with the buckling and pressing pipe body axis in the same direction as the power source has the advantages of small thrust area of the hydraulic oil cylinder, fewer machine heads and hydraulic assemblies, compact structure, light weight, economical production, manufacturing and assembly cost and simple process.

But the limitation of the design structure leads the inevitable shrinkage and expansion amount and the throughput of the die holder of the crimping machine to be smaller, and the trafficability and the adaptability of the crimping special-shaped connecting piece to be greatly limited. And because the reason of the single-action oil cylinder buckles the die holder and buckles and presses and have axial displacement during operation, the easy emergence buckles when pressing the connecting piece and presses the connecting piece tapering discrepancy, buckles the unable stable accurate positioning scheduling problem in position. Is not beneficial to batch and automatic production operation.

And the ultra-thin vertical withhold press that withholds the body axis and power supply direction vertically has increased withhold press die block and has received the expansion volume and throughput because of its certain structural rationality, the effectual trafficability characteristic and the adaptability when having improved withhold the press and withhold heterotypic connecting piece. The ultra-thin vertical crimping machine has the defects that under the same crimping range or the same crimping force, a hydraulic oil cylinder used by the ultra-thin vertical crimping machine with the axis of the crimping pipe body perpendicular to the direction of a power source has large thrust area, a machine head and hydraulic components are multiple, the volume and the weight of the oil cylinder and a machine frame are large, the production, manufacture and assembly costs are large, the process is complex, meanwhile, radial center displacement also exists during the crimping work due to the single-action oil cylinder, and certain limitation exists in the actual use process.
