Double-station upsetting female die shifting device and using method

Abstract

The invention provides a double-station upsetting female die shifting device and a using method. Comprising a lifting sliding block (1), a front limiting block (2), a front moving block (3), an upper female die base (4), a lower female die base (5), a workbench (6), a rear limiting block (11) and a rear moving block (12). The lifting sliding block (1) is connected with the upper female die base (4) through a front limiting block (2) and a rear limiting block (11). The workbench (6) is connected with the lower female die base (5) through the front limiting block (2) and the rear limiting block (11). According to the double-station upsetting female die shifting device, through ingenious cooperation of all parts, that is, two-pass continuous upsetting of a workpiece is achieved on a single main machine, the female die is reliable in shifting, stable in guiding and compact in structure, the manufacturing cost is greatly reduced, and the investment cost is saved.

Description

technical field [0001] The invention relates to the field of steel tube upsetting; in particular, it relates to a double-station upsetting concave die shifting device and a method for using the same. Background technique [0002] At present, in the production of steel pipe end upsetting, due to the limitation of the process, some specifications of the steel pipe require two consecutive upsetting forgings. In the existing production, two single-station upsetting machines are often arranged, and each upsetting machine has a separate upsetting forging machine. Forging once, the investment is large and the efficiency is low. There is an urgent need to develop a double-station upsetting machine. However, the biggest technical difficulty in developing a double-station upsetting machine is the problem of the displacement of the double-station die. There are also reports on the displacement problem in the prior art, but the equipment used in the prior art is complex, expensive, and...
