Description

Technical Field

[0001] This utility model relates to a press accessory and a press, and more particularly to an integrated casting press upper beam and a press using the same. Background Technology

[0002] The Chinese patent "Large Tonnage Small Table Precision Hydraulic Special Equipment - Hydraulic Press Upper Beam and Processing Method" (Publication No.: 104494197A), published on April 8, 2015, includes: an upper panel, a lower panel, and stiffening plates. The upper panel and the lower panel are respectively welded to the stiffening plates. The upper panel and the lower panel have coaxial main cylinder holes. The lower panel has a first washer with a thickness greater than that of the lower panel. The first washer is welded to the lower panel and the stiffening plates. The main cylinder hole of the lower panel is located on the first washer. Because the first washer is directly welded to the stiffening plates, stress concentration that might occur if the first washer were directly welded to the lower panel can be prevented. This press uses a welding process to connect the upper panel, lower panel, and stiffening plates for loading. Due to the need to ensure the structural strength of the upper beam, a large number of stiffening plates are required. Welding these stiffening plates together and between the stiffening plates and the upper and lower panels is very troublesome, which greatly reduces the processing difficulty. Utility Model Content

[0003] This utility model proposes an integrated casting press upper beam and a press using the same, which solves the problem of troublesome welding of stiffening plates, upper panels and lower panels in the prior art.

[0004] The purpose of this utility model for an integrated casting press upper beam is achieved through the following structure, which includes: an upper plate and a lower plate, with a stiffening plate between the upper plate and the lower plate, the upper plate, the lower plate and the stiffening plate being integrally cast into a box body, and the box body having guide column connection holes.

[0005] The upper plate is provided with an integrally formed lifting lug.

[0006] The upper plate has a perforation.

[0007] The reinforcing rib inside the box has two perforations.

[0008] The upper plate is provided with a boss, and a through hole is located on the boss.

[0009] Another objective of this utility model is to provide a press using the above-mentioned integrated casting press upper beam, which includes: an integrated casting press upper beam, a base, a guide column provided between the base and the integrated casting press upper beam, a pressure plate movably connected to the guide column, and a pressure plate drive device connected to the pressure plate.

[0010] The base includes: a seat body, a piston chamber on the seat body, and a hydraulic port on the seat body, the hydraulic port being connected to the piston chamber.

[0011] The piston of the pressure plate drive device is located inside the piston chamber.

[0012] The upper plate, lower plate, and stiffening plate of this invention are integrally cast into a box body, which greatly reduces the difficulty of processing, improves processing efficiency, and the overall structural strength is high, making it less prone to weld failure during product pressing. Secondly, by setting perforation one and perforation two, it not only reduces weight but also facilitates heat dissipation during hot pressing. Attached Figure Description
