Problems solved by technology

[0002] Special-shaped pipe profiles have been gradually applied to various types of excavator cabs, which have significantly improved the structural strength of the cab. Since the sections of the cab frame profiles are mostly complex, it is necessary to bend the profiles with complex cross-sectional shapes into the arc required for design. great difficulty
Moreover, the cooling effect is not good when cutting the special-shaped tube, which makes the post-processing very inconvenient

Embodiment Construction

[0010] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0011] A method for processing special-shaped pipes for excavator cabs: firstly uncoil the plates, enter the uncoiled plates into the edge trimming device for edge trimming, then shape the plates into round pipes through the roller device and weld them at the gaps, and then The round tube is rolled into a square tube, and then shaped by a rolling machine, cut by a synchronous cutting machine, and a cooling device is installed at the cutting point of the square tube to make a shaped special-shaped tube. The pipe processed by the method can make the square pipe with complex geometric section meet certain curvature requirements, and the production rate is high.

[0012] A metering device is provide...

Abstract

The invention discloses a method for machining special-shaped pipes for cabs of excavators. The method includes uncoiling plates; shaping the plates by the aid of a roll device until circular pipes are formed, and welding joints of the circular pipes; rolling the circular pipes until square pipes are formed; shaping the square pipes by the aid of a roller press; cutting off the square pipes by the aid of a synchronous cut-off machine; arranging cooling devices at cut-off positions of the square pipes and manufacturing and forming the special-shaped pipes. The method has the advantages that certain curvature requirements on the square pipes with complicated geometrical cross sections can be met by the pipes machined by the method, the production yield is high, the problem of uneven cooling due to a single-side spraying mode can be solved, and the beneficial effect is obvious.

Description

technical field [0001] The invention relates to a processing method for a special-shaped pipe used in an excavator cab, in particular to a processing method for a square pipe used in an excavator cab. Background technique [0002] Special-shaped pipe profiles have been gradually applied to various types of excavator cabs, which have significantly improved the structural strength of the cab. Since the sections of the cab frame profiles are mostly complex, it is necessary to bend the profiles with complex cross-sectional shapes into the arc required for design. Great difficulty. Moreover, the cooling effect is not good when cutting the special-shaped tube, which is very inconvenient for post-processing. At present, steel plate pressing parts are generally used to replace the application of special-shaped pipe profiles to make up for the lack of technology. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a proces...
