Description

A kind of U-shaped beam extruder with liner plate and rack-and-pinion centering body and joist device
Technical field
The invention belongs to machining manufacturing equipment field, refer more particularly to the special equipment of a kind of weighing apparatus production and a kind of U-shaped beam extruder.
Background technology
As shown in Figure 1, a kind of U-lag girder steel (being called for short U-shaped beam), being important component part during existing automobile weighing scale platform manufactures, is main spandrel girder in weighing platform structure, and the automobile load of tens tons, up to a hundred tons is welded to form weighing platform to bear primarily of the U-shaped beam of these varying numbers and intensity; Different according to magnitude of load, these U-shaped depths of beam, length are different, and some thicknesss of slab are different, and some width are different; Current weighing apparatus manufacturer mainly conventional U-shaped trammel lattice is the U-shaped beams according to the supporting differing heights of different tonnage and length, highly general at 250mm to 500mm, length is generally at 4m to 9m, the each producer of width differs, general at 200mm to 300mm, it is generally identical that each producer commonly uses U-shaped beam width, also has individual product to use different in width U-shaped beam; It is all fold at the upper a lot of of bender (a kind of standard machine tool) by manually lifting band steel (blank is band steel) that existing weighing apparatus producer processes these U-shaped beams, needs multiple tracks bending to be repeatedly shaped; In conventional U-shaped beam, longer Yi Tiaoliang weighs about 400kg, and need five to six people able-bodied laborers to operate, general U-shaped beam also wants 3 ~ 4 operative, and labour intensity is large; A lot of producer has to that long beam is changed into more piece short beam and respells weldering and form, and efficiency is low, poor quality.
Summary of the invention
The object of the invention is to overcome above-mentioned existing backward technology and a kind of U-shaped beam extruder with liner plate and rack-and-pinion centering body and joist device is provided, it is a kind of special equipment, want technical solution problem to be: described extruder is the U-shaped beam once suppressed with mould, and can many specification products be produced, must be convenient in demoulding, product undercarriage is convenient, reach that yield rate is high, good product quality, production efficiency are high, labour intensity is little, use labour less, saves production cost.
For achieving the above object, the present invention is achieved through the following technical solutions:
