Abstract

The invention relates to a large-sized forcing press base installation method, pertaining to the large-sized forcing press technical field. A horizontal concrete base delve is preset under a concrete base at the left side of the large-sized forcing press; threaded studs of six tension rods are sleeved with jackets and then are disposed into the horizontal concrete base delve; a base beam is mounted on the concrete base and then is adjusted to position; No.2 base is hung on the base beam to position and then No.3 base is hung on the base beam, aligning with the No.2 base; the No.3 base is moved leftwards by a jack to be tenoned with the No.2 base; No.4 base is hung on the base beam, aligning with the No.3 base; the No.4 base is moved leftwards by a jack to be tenoned with the No.3 base; No.1 base is hung at the left of the No.2 base and No.5 base is hung at the right of the No.3 base; the positions of the five bases are adjusted; the tension rods are threaded to the bases and nuts are screwed into the threaded studs at the left and the right ends of the tension rods; the studs and the nuts are heated under thermoelectric couple and then the nuts are turned to set an angle.

Description

technical field [0001] The invention relates to a method for installing a base of a large press, belonging to the technical field of large presses. Background technique [0002] At present, the known large-scale and heavy-duty equipment foundation base is multi-block combination type. The base base is a key component to ensure the operation accuracy of the equipment. The 150MN hydraulic press is one of the largest hydraulic presses in the world. Its base base has a total weight of 800 tons and an asymmetrical shape. General lifting equipment cannot be hoisted, the structure is tight, the installation space is narrow, and the relative position requires precise coordination; the six tie rods are easy to be damaged by stud bolts, and cannot be installed after being damaged. After the damaged thread is repaired, the connection strength will be reduced; each tie rod is 8 meters Long, the radial gap between the tie rod and the mounting hole of the base is 10mm, and the horizontal ...
