Description

Opening size adjusting device of column hydraulic machine

Technical Field

The utility model belongs to the technical field of the post hydraulic press, concretely relates to post hydraulic press opening size adjusting device.

Background

With the increase in the production speed of social substances, various and small-batch production modes have been developed. Shortening the auxiliary time, adapting to different molds, expanding the functions of equipment and improving the social productivity are the development trend of the technical update of manufacturing equipment. For four-column hydraulic machines with fixed opening sizes for installing moulds of different heights, a potential crisis appears in intense social competition. The equipment has the process actions necessary in the production process, and also has the advantages of shortening the auxiliary time and improving the automation. The die with different heights is met under the condition of the existing resources, so that the machine tool is simple and convenient to operate and saves labor, the labor intensity for installing the die is reduced, and the highest working efficiency is achieved.

At present, most of equipment produced by forging manufacturers adopts a fixed size for the distance (opening size) between a workbench and a sliding block of a machine tool or is manufactured according to the specified opening size of a use unit so as to meet the requirement of installing a die, and enterprises adopt chain transmission, so that the precision and the strength can not meet the general process requirement. When the size (also called opening size or closing height) between the workbench and the slide block is fixed, if the mold is used for pressing the workpiece, the closing height of the mold is different according to different workpiece heights; if the closing height of the mold is smaller than the design size of the equipment, the process requirement is generally met by adding a backing plate on the working table surface; if the closing height of the die is larger than the design size of the equipment, the process requirement cannot be realized, and the process requirement must be completed by equipment technology modification or purchase of a new machine tool. But can not thoroughly solve the problems of the pressing process for installing parts with different heights and precision dies, namely parts with different depths and the same tonnage, overlong idle stroke, or more exposed piston rods, easy pollution and corrosion, low production efficiency and increased manufacturing cost of the oil cylinder. And the opening size adjusting device of the column hydraulic machine in the prior art often does not have a fixing device after adjustment, so that the column hydraulic machine cannot bear larger pressure.
