Plate frame hydraulic press for mold pressing of large blocks and plates

Abstract

The invention discloses a plate frame hydraulic press for mold pressing of large blocks and plates, and belongs to a brick making machine. The plate frame hydraulic press is characterized by mainly comprising a frame, upper and lower pressing devices, upper and lower movable crossbeam devices, a mold frame fixing device, a safety device and an auxiliary cylinder device, wherein the frame mainly comprises front and back main boards, a cylinder fixing plate, a main connecting screw and a spacer bush; the upper pressing device mainly comprises an oil tank, an upper main cylinder and an upper movable crossbeam; the lower pressing device mainly comprises an oil tank, a lower main cylinder and a lower movable crossbeam; an upper guide device and a lower guide device mainly comprise a guide slider, a sliding plate, a sliding plate fixing plate, an adjusting plate and adjusting bolts respectively; safety hooks are arranged diagonally between upper parts of inner side faces of the front and back main boards of the frame and the upper movable crossbeam; the auxiliary cylinder device mainly comprises an auxiliary cylinder base and an auxiliary cylinder; and the mold frame fixing device is arranged on the middle part of the left and right sides of rectangular holes of the front and back main boards. The plate frame hydraulic press has high rigidity and high fatigue resistance.

Description

technical field [0001] The invention belongs to a brick making machine, in particular to a hydraulic machine for pressing large blocks and plates. Background technique [0002] The building materials pressed by the press, such as blocks and plates, are all new building materials popularized after the ban on sticking (no clay bricks) and no solid (no solid bricks) in my country, so as to achieve energy saving, consumption reduction and protection of cultivated land the goal of. The traditional press structures that have lasted for hundreds of years include integral welded structures, three-beam and four-column structures, and prestressed composite frame structures. Small and medium-sized hydraulic presses generally adopt an integral welded structure, while large-scale hydraulic presses generally adopt a three-beam and four-column structure or a prestressed composite frame structure. Welding presses are prone to welding deformation, and the manufacturing process of the press ...

AI Technical Summary

Problems solved by technology

Welding presses are prone to welding deformation, and the manufacturing process of the press is complicated and the precision is low; because the copper sleeves of the three-beam and four-column columns are severely worn in dusty environments, the manufacturing process is complicated, and the manufacturing and use costs are high; the prestressed composite frame Although the structure has its advantages, due to the deviation of the mechanical properties of the casting itself, each part is very thick, which brings challenges to transportation and manufacturing, and the manufacturing cycle is long
