Description

Special pressure rack for machining line-heating plates by hull plates

(1) technical field

Special tooling equipment when the utility model relates to a kind of hull firer flame forming plate particularly relates at processing hull bow stern and has the linear outside plate processing that bigger two-way curvature changes.Belong to the shipbuilding equipment technical field.

(2) background technology

In shipbuilding hull construction process, ship hull plate processing is a very important manufacturing procedure, must could realize through the processing method of firer's flame forming plate and have the linear outside plate processing of two-way curvature.Flame forming plate is exactly the principle of expanding with heat and contract with cold according to steel plate, with oxyacetylene torch ship hull plate is carried out local heat, and water cools off then, makes the distortion of ship hull plate generation local contraction, thereby reaches the purpose of processing.General width of heating is 1.5～2 times of steel plate thickness, every heating cooling once, the amount of contraction of steel plate has only about 1mm, and the linear variation of hull bow stern outside plate is big and thickness of slab is thicker, often all be heating trace road on the steel plate, also do not reach processing request, need carry out the heating cooling second time, and steel plate material in the post bake cooling procedure can turn cold and become fragile, and is easy to generate crackle.It is time-consuming to only depend on the heating cooling contraction distortion of steel plate to carry out the processing of bow stern outside plate flame forming plate, and Forming Quality is relatively poor, if need to increase external force, the general driving foundary weight that plays that adopts is pressed on the outside plate the omnidistance cooperation of both dangerous again driving.

(3) summary of the invention

The purpose of this utility model is to change only to rely on heating cooling contraction distortion to carry out the processing of bow stern outside plate flame forming plate, adopts a kind of special pressure rack for machining line-heating plates by hull plates of the impressed pressure of conveniently adjusted stress action spot.

The purpose of this utility model is achieved through the following technical solutions: a kind of external plate machining line-heating special pressure rack, comprise two portal frames, two longerons and two jack, each portal frame comprises lower and upper cross-member and left and right pillar, upper and lower crossbeam is combined into body structure by steel plate, column is made by seamless steel pipe, having on the outside of the lower panel of entablature can be for chute fixing, that the adjusting longeron is used, and longeron can carry out passing through bolting after the left and right adjusting according to processing outside plate width in portal frame; Described longeron is combined into I-shape construction by steel plate, the top panel both sides of longeron have for the entablature fixedly eye plate of usefulness and the chute of adjusting portal frame longitudinal separation; Described jack by four fixedly horse and base steel plate be connected and fixed, this base steel plate utilizes four lower panels that are connected with the lower panel of longeron and can prolonging longeron of riding to seesaw again, regulates the stressed position of jack pair steel plate arbitrarily.

Positive progressive effect of the present utility model is:

Tooling device is made simple, changed in the past firer's flame forming plate processing hyperbolic plate of being outside one's consideration and utilized the traditional operation technology of foundary weight as applied force, the conveniently adjusted position of pressure frame to processing outside plate stress point, easy to operate, safe and reliable, do not need to drive a vehicle long-term the cooperation, high efficiency is to use the twice of traditional operation processes work efficiency.Longeron can two use or single uses simultaneously.Can conveniently decompose when pressure frame does not use and take apart, the placement floor space is little.

(5) specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe structure of the present utility model and processing method thereof in detail.

Referring to Fig. 1～3, Fig. 1 is the structure front view of the utility model special pressure rack for machining line-heating plates by hull plates.Fig. 2 is the vertical view of Fig. 1.Fig. 3 is the side view of Fig. 1.By Fig. 1, Fig. 2 and Fig. 3 are as can be seen, the utility model special pressure rack for machining line-heating plates by hull plates, comprise: two portal frames 1 and two longerons 2 and two jack 3, each portal frame 1 is by lower and upper cross-member and left and right pillar 12 and column base plate 121, column bracket 122 is formed by combining, on, sill is combined into body structure by steel plate, column 12 is made by seamless steel pipe, having on the outside of the lower panel 111 of entablature can be for fixing, regulate the chute 1111 that longeron is used, longeron can carry out fixing by bolt 8 after the left and right adjusting according to processing outside plate width in portal frame; Described longeron 2 is combined into I-shape construction by steel plate, top panel 21 both sides of longeron have for the entablature 11 fixedly eye plate 211 of usefulness and the chute 212 of adjusting portal frame longitudinal separation; Described jack 3 by four fixedly horse 31 be connected and fixed with base steel plate 33, this base steel plate 33 utilizes four to ride and 32 be connected with the lower panel 22 of longeron and the lower panel 22 that can prolong longeron seesaws again, regulates the stressed position of jack pair steel plate arbitrarily.

Processing method is as follows:

When the processing outside plate, respectively two portal frames are located according to processed outside plate length, linear situation, hang in processed outside plate 5, fill up appropriate stupefied wooden 6, width according to processed outside plate, determine that longeron usage quantity and the longeron 2 that jack 3 will be housed lift up in two portal frames 1, and regulate position, the left and right sides, longeron is fixing with bolt 8 with two portal frames respectively.According to the linear adjusting jack front and back position of processed outside plate, according to the jack stroke, between processed outside plate and jack, add stupefied wooden 4 and billet 7 of proper height, hold out against jack, make jack stressed.Begin processed outside plate heating and water cooling are progressively held out against jack simultaneously, make jack be in continuous stress.Linear and the processing situation according to processed outside plate can be regulated about longeron or the jack front and back position, continues extreme misery outside plate operation construction.In case of necessity, can under the cooperation of driving, regulate the front and rear fulcrum position of processed outside plate, make stress point more reasonable, accelerate processing progress and construction quality.After processing reaches quality requirement, under the cooperation of driving, hang out processed outside plate,, size linear according to next the piece outside plate that will process readjusts various distances, carries out new round operation.
