Embodiment Construction

[0023] At present, the process adopted in manufacturing the forklift beam is to directly roll the billet into the forklift beam profile steel with the beam end face size, and then cut the material according to the length of the finished component. Forklift beam steel has a variety of 1.5 tons to 5 tons of forklift steel, which is used as a load-bearing component and is the main material for manufacturing the beam of a forklift load-bearing component.

[0024] The rolling process of forklift beam section steel is as follows;

[0025] The -- in Figure 1-11 indicates the rolling process; after the reciprocating rolling pass pattern 3-6, after 4 passes exiting the pass pattern, each turn right at an angle of 90°, and then enter the next pass pass rolling.

[0026] 1), the material meets the user's requirements of chemical composition 150mm 2 The square steel billet is cut into a certain length size according to the process requirements, such as the size of 2.5-2.8m.

Abstract

A forkman beam steel rolling technics method is provided, which processes as the following technics flow: firstly, bait 150mm2 square steel blank of a chemical composite according to the requirements of the user to form a fixed size according to the requirements of the technics; secondly, the blank after baiting enters into a heat furnace to increase to 1250 DEG C., in order to comply with the temperature range of material rolling for beginning rolling; thirdly, the blank after multiple gates of back and forth rolling, enters into a forming rolling gate to produce forkman beam steel shape; fourthly, the rolling piece with the forkman beam steel shape after the flatting of the last gate, makes the size of the forming steel interface and tolerance comply with the size requirements of producing forkman load beam, the final rolling temperature is 900 DEG C.; fifthly, after nature cooling, according to the supply requirements and the requirements of the drawings, remove the blue roll scale on the surface of the rolling piece, to proceed the last heat process or various straightening process.

Description

Technical field: [0001] The invention relates to the technical field of metal hot-working rolling manufacturing, and relates to a rolling process method for a forklift beam profile steel. Background technique: [0002] Forklift beam steel is the main material for the manufacture of forklift load-bearing member beams. It is a rolled profile. At present, the technological method of the domestic forklift load-carrying member cross beam is mainly made of steel plate material with the same thickness and material through gas cutting and machining. Its process procedure is more, and time-consuming is longer. The most important thing is that the cost is high and the production efficiency is low. If the gas cutting direction is perpendicular to the fiber of the sheet material, the mechanical strength of the beam will be reduced, which will affect the product quality. Invention content: [0003] In order to overcome the problem of low strength of the forklift beam by gas cutting ...
