Single-column universal hydraulic machine

Abstract

The invention relates to a single-column universal hydraulic machine. The single-column universal hydraulic machine comprises an equipment box, protective frames and sponge plates; a reinforcing platform is connected to the top end of the equipment box, a powder blocking frame is arranged in the middle of the interior of the reinforcing platform, a mold mounting frame is arranged at the top end ofthe powder blocking frame, and supporting frames are fixed to the two sides of the top end of the reinforcing platform; and the tops of the supporting frames are connected with a top frame plate, theprotective frames are fixed to the bottom of the top frame plate, the interior of the protective frames is connected with a hydraulic cylinder, a lifting frame is arranged at the bottom end of the hydraulic cylinder, and a pressing frame is arranged at the bottom end of the lifting frame. The single-column universal hydraulic machine has the beneficial effects that a user can add lubricating oilbetween the sponge plates, the added lubricating oil liquid is adsorbed between the sponge plates through the adsorption effect of the sponge plates, when the lifting frame and the pressing frame which ascend and descend are clamped between the protective frames, the stressed sponge plates add the lubricating oil liquid between the lifting frame and the pressing frame, liquid can be added for internal maintenance, and the up-and-down movement vitality of the single-column universal hydraulic machine is improved.

Description

technical field [0001] The invention relates to the technical field of a single-column universal hydraulic press, in particular to a single-column universal hydraulic press. Background technique [0002] The hydraulic system of the single-column universal hydraulic press is located inside the fuselage. It has a beautiful appearance and is easy to operate. It is mainly suitable for metal products such as stretching, forming and pressing. It can also process non-metallic materials, pressing of powder metallurgy products, and shaft parts. Calibration, press-fitting of sleeve parts, shaping and trimming of metal products, etc., but there are many defects in the working process of single-column universal hydraulic presses, which affect the normal maintenance and equipment maintenance of single-column universal hydraulic presses. Make structural improvements. [0003] For the single-column universal hydraulic presses on the market, it is difficult to add internal maintenance, whi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a single-column universal hydraulic press to solve the problem of the single-column universal hydraulic press on the market proposed in the above-mentioned background technology. It is difficult to add internal maintenance, which affects the up and down movement of the single-column universal hydraulic press. It is conducive to product structure placement, and the internal station adjustment of the platform is difficult, resulting in product position deviation, reducing the safety factor of the single-column universal hydraulic press, and powder metallurgy products without corresponding protective structures.
