Jack hydraulic press

Abstract

The invention discloses a jack hydraulic press, which belongs to the technical field of presses, and comprises a machine frame comprised of an upper beam, a lower beam, first and second trailing arms which are connected between the upper beam and the lower beam and longitudinally parallel to each other, a work rest arranged at the first trailing arm and the second trailing arm and corresponding to the space between the upper beam and the lower beam, a jack body arranged on the outer side of the first trailing arm or the second trailing arm, and an under-thrust device arranged at the upper beam and connected with a hydraulic circuit of the jack body. The jack hydraulic press is characterized in that: the upper beam is in a square structure which is closed on four sides and hollow along the up-and-down direction, the inner walls of a pair of wall bodies along the length direction of the upper beam are fixedly provided with a guide rail respectively, two guide rails are parallel to each other, and the under-thrust device is slipperily arranged on the guide rails. The jack hydraulic press has the advantages of saving operational labor, achieving high adaptability and reducing the labor intensity of the operator.

Description

technical field [0001] The invention belongs to the technical field of presses, and in particular relates to a jack hydraulic press. Background technique [0002] Compared with large-scale hydraulic presses (also known as hydraulic presses), jack hydraulic presses can play a role in filling gaps, which are manifested in wide adaptability to application sites, small size, convenient operation and low investment. On the contrary, large-scale hydraulic machines need to be equipped with corresponding hydraulic stations. The overall volume is large, the floor area is large, the equipment cost is high, and investment and management are difficult. It is precisely because the jack hydraulic press has the irreplaceable characteristics of a large hydraulic machine, so it can be applied to the production line of the factory, construction site, electromechanical equipment repair industry, vehicle maintenance industry and family, etc. Take the production line of the factory as an exampl...

Problems solved by technology

[0003] In the patent literature, especially the Chinese patent literature, there is a technical solution of a jack hydraulic press. The utility model authorization announcement number CN201205566Y discloses a jack hydraulic press, which is suitable for straightening and bending various components, but in addition to the configuration of the jack , also needs to be equipped with a set of hydraulic transmission device (see the penultimate line on the second page of the patent application), so the volume is relatively large, it is picky about the application, and the flexibility in the process of use is poor. The submersion device directly acting on the processed parts (that is, the so-called jack and press die in the patent) cannot move to the left, resulting in the limitation of the working range. labor-intensive

[0004] Although the manual hydraulic pre...
