Problems solved by technology

[0004] The cost of developing a set of heavy-duty vehicle beam molds at the current market price is as high as 2.3 million yuan. If more than a dozen sets of molds need to be developed, the cost is high and the development cycle is long, which greatly increases the manufacturing cost of the beam production. The mold length is 6m-13m , 0.8m-1.2m wide, the production site covers a large area, and it also brings a lot of inconvenience to production and mold management

Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] A heavy-duty vehicle U-shaped girder width steplessly adjustable mold, including an upper mold combination and a lower mold combination, the upper mold combination includes several upper mold assemblies 23, and the lower mold assembly includes the same number of upper mold assemblies The lower mold assembly 24; the upper mold assembly 23 and the lower mold assembly 24 correspond one-to-one, as figure 1 shown.

[0043] The lower mold assembly 24 includes a lower base 1, and the upper surface of the lower base 1 is fixedly installed with two die holders 8 with protrusions at a certain distance apart, and the distance between the die holders 8 is adjusted according to the width of the automobile frame. Sure.

[0044] The upper mold assembly 23 includes an upper base 2, and the lower surface of the upper base 2 is fixed with a convex mold...

Abstract

The invention relates to mold adjusting devices for vehicle U-shaped crossbeam manufacturing, particularly to a stepless width adjusting mold of a heavy-duty vehicle U-shaped crossbeam. The stepless width adjusting mold of the heavy-duty vehicle U-shaped crossbeam comprises an upper mold combination and a lower mold combination, the upper mold combination comprises a plurality of upper mold modules, the lower mold combination comprises a plurality of lower mold modules which are identical to the upper mold modules in number, and the upper mold modules and the lower mold modules are in one-to-one correspondence; every lower mold module comprises a lower base, and the upper surface of the lower base is movably provided with two cavity mold fixing seats with protrusions at a certain interval; every upper mold module comprises an upper base, the lower surface of the upper base is fixedly provided with a terrace mold guide key through bolts, which is provided with a step-shaped cross section, both ends of the terrace mold guide key are respectively provided with a terrace mold fixing seat, and the upper portion of every terrace mold fixing seat is provided with a stepped slot matched with the corresponding terrace mold guide key in a stepping mode. The stepless width adjusting mold of the heavy-duty vehicle U-shaped crossbeam is reasonable in design and achieves stepless adjustment of different material thicknesses and widths of the vehicle U-shaped crossbeam by means of the C-type structure and the adjustment wedge structure of the terrace mold fixing seat.

Description

technical field [0001] The invention relates to a mold adjusting device for manufacturing U-shaped girders of automobiles, in particular to a stepless adjustable mold for the U-shaped girders of heavy-duty automobiles. Background technique [0002] In order to meet the demand for mass production of automobile U-shaped girders, it is considered to adopt the die stamping forming process: firstly, the product quality is stable, and secondly, the production efficiency is improved. [0003] However, since the U-shaped girders of heavy-duty vehicles have various widths and thicknesses, ranging from 230mm to 320mm in width and 4mm to 10mm in thickness, in order to realize the stamping production of multi-variety and multi-thickness girders, each product thickness corresponds to a width A large girder requires the development of a set of molds, and in the end more than a dozen sets of molds need to be developed. [0004] At the current market price, the cost of developing a set of ...
