Problems solved by technology

[0002] Urban ramp steel box girders are developing fast, large in scale, large in number and complex in shape. The bottom of the wing joists on both sides of the steel box girders mostly use "S"-shaped curved plates, which are difficult to manufacture and consume manpower, material and financial resources.
In view of the short construction period and tight construction period of urban ramp steel box girders, a tooling for the production of curved plate units was designed and invented, mainly for the production of "S" curved plate drag beams

Embodiment 1

[0010] Embodiment 1: with reference to attached Figure 1-5 . A tooling for making a curved panel unit, which is composed of a counterweight device 1, a clamping device 2, a supporting device 3, a tooling foundation 4, and a pushing device 5; On the long backing plate, the thrusting device 5 is fixed on the long backing plate and the push rod of the pushing device 5 passes through the supporting device to cooperate with the joist bending plate 6 on the supporting device 3, and the counterweight device 1 is located at the joist bending At one end of the plate 6 , the web 7 of the joist is located on the bent plate 6 of the joist. Support device 3 is made up of horizontal support, vertical support. The clamping device 2 is connected by an oblique support and a horizontal support device, and the counterweight device 1 and the pushing device are composed of a counterweight and a jack.

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, a method for manufacturing tooling for curved plate units and manufacturing joists, Adjust the support device 3, spot-weld the non-counterweight side of the "S" curved bottom plate of the joist beam, and place the "S" curved bottom plate 6 of the tow beam behind the horizontal support device 3 after the linear adjustment, and put the counterweight in place ; The towing beam web 7 is fastened in place, and the non-counterweight side towing beam web 7 is positioned; Unlock the counterweight device 1, use the pusher device 5 to assemble and position the counterweight side curved bottom plate 6 and assemble and weld the side joist.

Abstract

The invention relates to a manufacturing tooling and method for curved plate units capable of completing the manufacture of "S"-shaped towing beams of different shapes by using simple tooling, which consists of a counterweight device, a clamping device, a supporting device, a tooling foundation and a pushing device; There is a long backing plate in the middle of the tooling foundation, the supporting device is located on the long backing plate, the pushing device is fixed on the long backing plate and the push rod of the pushing device passes through the supporting device and the joist bending plate on the supporting device To cooperate, the counterweight device is located at one end of the joist bend, and the joist web is located on the joist bend. Advantages: First, the structure is simple, convenient and easy to operate, and has strong practicability, eliminating the need for bending equipment and the bending process of "S"-shaped bending plates, and can be used for the manufacture of "S"-shaped towing beams of different shapes, and the manufacturing accuracy is also high. It is easy to guarantee; secondly, and more importantly, the production cycle of the curved plate unit is greatly reduced; thirdly, the labor intensity is reduced, and the production efficiency of the drag beam unit is improved.

Description

technical field [0001] The invention relates to a manufacturing tool and method for a curved plate unit capable of manufacturing "S"-shaped towing beams of different shapes by using simple tooling, and belongs to the field of special tooling manufacturing. Background technique [0002] Urban ramp steel box girders are developing fast, large in scale, large in number and complex in shape. The bottom of the wing joists on both sides of the steel box girders mostly use "S"-shaped curved plates, which are difficult to manufacture and consume manpower, material and financial resources. In view of the short construction period and tight construction period of urban ramp steel box girders, a tooling for the production of curved plate units is designed and invented, mainly for the production of "S" curved plate drag beams. Contents of the invention [0003] Design purpose: To design a method that not only reduces the requirements of the manufacturing unit for bending equipment, bu...
