Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: straightening the I-beam through flame straightening generally requires multiple times of flame straightening to meet the industrial requirements, while the manual straightening of the I-beam Straightening steel is time-consuming, labor-intensive and inefficient; in summary, the efficiency of straightening I-beams on airtight doors in the prior art is relatively low

Embodiment Construction

[0043] The following is attached Figure 1-10 The application is described in further detail.

[0044] The so-called straightening machine is a machine used to straighten shaft parts. Through straightening, the ideal straightness requirements or rotation accuracy requirements can be obtained to ensure that the parts can meet the assembly accuracy or obtain the minimum cutting process in the next process. margin.

[0045]The I-beam includes a web, and side plates are provided at both ends of the web, and the side plates are parallel to each other and perpendicular to the web.

[0046] The embodiment of the present application discloses a straightening machine used for manufacturing airtight doors. refer to figure 1 A straightening machine for airtight door manufacturing includes a transmission mechanism 1 and a straightening mechanism 2 arranged in sequence, and the straightening mechanism 2 is close to one end of the transmission mechanism 1 .

[0047] refer to figure 2 ...

Abstract

The invention relates to the field of workpiece straightening, in particular to a straightening machine for manufacturing an air-tight door, the straightening machine comprises a conveying mechanism and a workbench which are arranged in sequence, wherein a jacking plate hole is formed in the workbench, and the conveying mechanism is used for conveying I-shaped steel machined by the straightening machine to the position above the jacking plate hole in the workbench; a jacking assembly capable of penetrating through the jacking plate hole to jack up the I-shaped steel is arranged below the jacking plate hole, and extrusion assemblies used for applying extrusion force to the I-shaped steel jacked up by the jacking assembly are arranged on the two sides of the upper portion of the jacking plate hole; a pressure drop assembly is arranged above the jacking plate hole and used for applying downward extrusion force to the I-shaped steel jacked up by the jacking assembly. The simple tractable vehicle axle lifting device has the effect of conveniently improving the straightening efficiency of the I-shaped steel on an air-tight door.

Description

technical field [0001] The present application relates to the field of straightening of workpieces, in particular to a straightening machine for the manufacture of airtight doors. Background technique [0002] In order to increase the strength of the airtight door, I-beams are used on the airtight door. The I-beam will be bent and deformed after being heated at high temperature. The cutting stress in the rough and fine machining process will also make the I-beam bend and deform. The quality of the I-beam used requires straightening the I-beam before installing it on the airtight door. [0003] The traditional straightening of I-beam generally adopts flame straightening and manual hand-held straightening tool straightening. Flame straightening uses local compression deformation generated during flame heating to shorten the longer part after cooling and eliminate deformation; while artificial Straightening mostly adopts manual hand-held straightening tools to repeatedly press...
