Problems solved by technology

[0004] At present, there is a large round hole in the center of the bottom of the press, which is used for blanking. This structure is not suitable for the disassembly of parts with wheels at both ends and the shaft length exceeds the stroke of the press. There are many parts of this type. It cannot be disassembled or requires tooling, which is time-consuming and labor-intensive. It also wastes materials and labor for tooling. For parts whose shaft length is greater than the stroke of the press, they cannot be disassembled.

Abstract

The invention discloses a 300T portal press and a pressing method. A traditional press does not adapt to detaching of parts of which two ends are provided with shafts and the shaft lengths exceed the stroke of the press. The 300T portal press comprises a machine body, wherein an oil cylinder (1) is arranged at the upper part of the machine body (2), the oil cylinder penetrates through the machine body and is connected with a pressing head (3); a bottom girder is arranged at the lower part of the machine body; a U-shaped opening (4) is formed in the bottom girder; an opening part of the U-shaped opening is arranged at the front part of the bottom girder; mounting grooves of connecting keys (6) and mounting screw holes of connecting bolts (7) are formed in two sides of the opening part at the front part of the bottom girder; the connecting keys are arranged on the corresponding mounting grooves of the connecting keys; a connecting plate (5) is arranged at the outer sides of the connecting keys through the connecting bolts. The invention relates to the field of machining, and in particular is applied to the 300T portal press and an operation method.

Description

[0001] Technical field: [0002] The invention relates to the field of mechanical processing, in particular to a 300T portal press and an operation method. [0003] Background technique: [0004] At present, there is a large round hole in the center of the bottom of the press, which is used for blanking. This structure is not suitable for the disassembly of parts with wheels at both ends and the shaft length exceeds the stroke of the press. There are many parts of this type. It cannot be disassembled or requires tooling, which is time-consuming and laborious. At the same time, it also wastes materials and labor for tooling. For parts whose shaft length is greater than the stroke of the press, they cannot be disassembled. [0005] Invention content: [0006] The purpose of the present invention is to provide a 300T portal press and a pressing method. [0007] Above-mentioned purpose realizes by following technical scheme: [0008] A 300T gantry press, which consists of: a bod...
