Abstract：

A new type of extrusion press with laminated plate column was introduced, and it made a breakthrough in the traditional round nut tightening structure. The pre-tightening force of tension column was established through preloading on the front end of the beam big “T” hook, and then adding the bolster plate between the beam and woodruff key after laminated rod elongated forcibly. The technical requirements and manufacturing difficulties of laminated plate column were analyzed. In order to overcome dislocations in processing and measuring of laminated plates caused by the rectangular slab deformation, the project of laminated pull rod cutting process under pre-stress straighten state was realized by setting aside processing block for both ends when laminated plate is cut to install special pre-tightening device. Therefore, the isometric and consistency of the four sets of laminated plate columns and combining surface of front and rear beam, and mating surface of woodruff key arc were ensured and met the design and assembling requirements. The manufacturing process of large laminated plate column was improved. It receives a successful result from the laminated plate column after installation, measurement and user feedback.
