Multi-station friction screw press

Abstract

The invention relates to a multi-station friction screw press which comprises a body, a multi-station mold, a slide block, a screw, a plurality of guide rails and a screw driving device, wherein the multi-station mold is arranged on the workbench of the body; the slide block is arranged above the multi-station mold; one end of the screw is inserted into the slide block and is rotatablely connected with the slide block, and the screw drives the slide block to move up and down; the plurality of guide rails are arranged on the body and are used for guiding the slide block, and the distance amongthe guide rails is suitable for the slide block to slide among the guide rails; the screw driving device is connected with the other end of the screw and can drive the screw to rotate forward or backward and simultaneously rise or fall; the ratio of the longitudinal height of the slide block along the length direction of the guide rails to the minimum transverse width of the size of the slide block is greater than 1.5; and the gap between the outer diameter of the screw and the minimum inner diameter of the opening at the inserting end of the slide block is 0.3-0.5mm. The invention provides an economical multi-station friction screw press which can be used for multi-station forging.

Description

technical field [0001] The invention relates to a press, in particular to a multi-station friction screw press. Background technique [0002] The characteristic of multi-station forging is that it can realize the forging of multiple stations at one time on one press. Compared with single-station forging, it has the following advantages: less investment in equipment, less workshop area, and no problem that forgings are easy to cool during long-distance transfer between two stations, thus affecting the quality of forgings. However, due to various factors such as the distribution of each station on the mold and the different forming forces required by each station, it is difficult to ensure that the pressure center of the mold coincides with the center of the press. Therefore, it is difficult to avoid during forging. There will be an eccentric load force that the mold reacts on the press. [0003] At present, the equipment that can carry out multi-station forging mainly inclu...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention lies in the fact that the slider of the traditional friction screw press in the prior art is prone to lead to failure of the screw when it bears an eccentric load, and cannot be applied to multi-station forging.
