Automatic fixing device for rolling fixture

Abstract

The invention discloses an automatic fixing device for a rolling fixture. The device is characterized in that: a fixing seat (2) is provided with a cylinder bracket (18), and a cylinder (1) is mounted on the cylinder bracket (18) through a fourth rotary shaft (19). A compaction block (6) and a cushion block (7) are sleeved on a pull rod (12); a lock nut (8) on the upper part of the pull rod (12) compacts the compaction block (6) and the cushion block (7); and the pull rod (12) passes through a rolling work platform (4), and a compaction spring (11) is sleeved on the lower part of the pull rod(12). One end of a rotary arm (16) is connected with a piston rod of the cylinder (1) through a third rotary shaft (17); and a roller (13) is arranged at the other end of the rotary arm (16) through a first rotary shaft (14), and resists against the lower surface of a flange at the lower end of the pull rod (16). Through the invention, quick replacement and automatic fixation of the rolling fixture are realized, the position precision and stability of the rolling fixture on the work platform are ensured, the size precision of the rolling section is guaranteed, the fixture replacing time is shortened, the production efficiency is improved, and the labor intensity of workers is reduced. Compaction is realized by use of spring force, the cost is lowered, and energy is saved.

Description

technical field [0001] The invention relates to the field of auto parts production, in particular to an automatic fixing device for rolling tooling, which is mainly used in rolling line equipment. Background technique [0002] All kinds of doors, window frames and decorative strips on automobiles are made of profiles through stretch bending and subsequent processes, while steel profiles are formed by rolling with strip materials. The rolling line includes a rolling machine and a rolling tool. The rolling machine can be equipped with various rolling tools to produce various profiles, and the rolling tooling is composed of groups of rollers designed according to the section of the profile. The rolling tooling needs Accurately, quickly and firmly fixed on the working platform of the roller press. Usually, the rolling tooling is manually fixed on the working platform of the rolling machine through the pressure plate and screws. This fixing method makes it time-consuming to repl...
