Flame rush-harvesting and rush-planting cutter sweep
Technical field
The utility model relates to cutter sweep, relates in particular to a kind of flame rush-harvesting and rush-planting cutter sweep.
Background technology
In pressure vessel is manufactured, pressure vessel body great majority are to be all made up of tens millimeters of ordinary carbon steel sheet materials to twenties millimeter, and wherein, what the mouth of pipe joint of pressure vessel adopted mostly is all the large root face technique of single V groove.Plate cutting, its groove processing are all completed by semi auto cutting machine.When plate cutting, in the time that needs stay root face, generally adopt two kinds of methods: one be root face hour, do not stay root face cutting, root face is by abrasive machine polishing; Its shortcoming is: group is to the bad control in gap, and root face amount is difficult to be consistent; Another kind is the method that adopts cutting twice, first cuts straight mouthful that is:, then beveling.Its shortcoming is: the cut end heat time to sheet material is double, and due in cutting process, the cut end heat time is longer, causes the deformation of sheet material and chemical composition to change, and the man-hour of waste is more.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of flame rush-harvesting and rush-planting cutter sweep, it is simple in structure, easy to operate, it not only can be with two rifles in the forward and backward cutting simultaneously of different angles, once cutting just can complete the requirement of large root face groove processing, has greatly improved the quality of cutting efficiency and welding; And, solve deformation and chemical composition change problem due to the cutting twice heating sheet material that causes.
The purpose of this utility model is realized by following technical scheme:
A kind of flame rush-harvesting and rush-planting cutter sweep, is characterized in that: comprising: dolly assembly, be arranged on cutter sweep and feeder on dolly assembly, wherein, feeder is provided with: gas distributor, and this gas distributor is connected with cutter sweep by air supply hose; Cutter sweep is provided with: cutting machine, be arranged on the front cutting torch on cutting machine body, rear cutting torch, wherein, be provided with a fixed head that is used for fixing respectively front cutting torch, rear cutting torch between front cutting torch, rear cutting torch, fixed head is provided with for front cutting torch, rear cutting torch and installs and the adjustment hole of adjustable range; Front cutting torch and rear cutting torch all can independently carry out laterally by being arranged on the axle in adjustment hole on fixed head, the adjusting of vertical, angle.
Described dolly assembly comprises: car body, be arranged on the walking roller of underneath its body; Car body 11 is box structure, in car body, be provided with motor, gear-box, direction of travel control valve and speed-regulating valve, wherein, walking roller is connected with motor by gear-box, change the electrode direction of motor by direction of travel control valve, thereby, change motor traffic direction, realize the variation that Cutting dolly advances or retreats two direction operations.
The bottom of described dolly assembly is provided with a parallel orbit of advancing for walking roller.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and it is simple in structure, easy to operate, it not only can be with two rifles in the forward and backward cutting simultaneously of different angles, and once cutting just can complete the requirement of large root face groove processing; And, greatly improve the quality of cutting efficiency and welding; Cutting efficiency has improved more than at least 100%; Reduce former abrasive machine polishing root face group inconsistent and that cause inconsistent to gap, the situations such as welding back cover difficulty; Meanwhile, reduce time of polishing and required consumptive material more than 50%, in the time having reduced construction cost, raised the efficiency, reduced preferably operating risk.

Detailed description of the invention
As shown in Fig. 1-Fig. 3, the utility model comprises: dolly assembly 1, be arranged on cutter sweep 2 and feeder 12 on dolly assembly 1, wherein, dolly assembly 1 mainly by car body 11, be arranged on car body 11 walking roller 13 below and form; Car body 11 is box structure, in car body 11, be provided with motor, gear-box, direction of travel control valve and speed-regulating valve, wherein, walking roller is connected with motor by gear-box, change the electrode direction of motor by direction of travel control valve, thereby, change motor traffic direction, realize the variation that Cutting dolly advances or retreats two direction operations; Negotiation speed control valve increases or reduces the electric current of motor, changes the speed of service of motor, realizes the change of carriage walking speed.To realize the control to cutting machine direction of travel and speed, reach the direction of cutting machine and the requirement of speed when different specification size steel plate is cut.
The bottom of above-mentioned dolly assembly is provided with a parallel orbit of advancing for walking roller 13.
Feeder 12 is mainly cutting machine and sufficient gas flow is provided and the cutting fire combustion of different-thickness steel plate is regulated, and is mainly provided with: gas distributor 121, this gas distributor 121 is connected with cutter sweep 2 by air supply hose 14.
As shown in Figure 3, cutter sweep 2 is provided with: cutting machine, be arranged on front cutting torch 21, rear cutting torch 22 on cutting machine body, wherein, between front cutting torch 21, rear cutting torch 22, be provided with a fixed head 23 that is used for fixing respectively front cutting torch 21, rear cutting torch 22, fixed head 23 is provided with for front cutting torch 21, rear cutting torch 22 and installs and the adjustment hole of adjustable range.Front cutting torch 21 and rear cutting torch 22 all can independently carry out laterally by being arranged on the axle in adjustment hole on fixed head 23, the adjusting of vertical, angle, to adapt to the requirement of various grooves processing.Realize the cutting to processing steel plate by horizontal and vertical fine setting.Meanwhile, by the change to front and back nozzle angle, realize the synchronous cutting to different groove form processings.By the change to front and back cutting torch longitudinal separation, realize the steel plate synchronous cutting to different-thickness.
As shown in Figure 4, use step of the present utility model is as follows:
1, apart from 160 millimeters of laid parallel tracks of plate line, fore-and-aft survey is guaranteed parallel track.
2, cutting machine is correctly put into track, while guaranteeing cutting machine, walking roller 13 can injection draw-in groove.
3, connect the band of gas, power supply, according to cut material, debugging gas pressure and cutting torch wind line, adjust the cutting machine speed of travel.The rapidoprint to adapt to.
4, require to adjust front and back nozzle angle according to processing cut, add man-hour at large root face, front cutting torch is vertical, and rear cutting torch is adjusted to 30 degree or 45 degree, cut for the first time by front cutting torch, rear cutting torch reserves root face, and bevel cut can the required groove of disposable acquisition subsequently.
5, according to the size in clout expanded by heating gap after front cutting torch cutting, suitably cutting torch transverse support bar after rotation, reach the object that strengthens or dwindle distance between the cutting torch of front and back, obtain suitable cutting opportunity, gap is too small returns slurry while easily causing rear cutting torch cutting, affect the Forming Quality of groove, apart from excessive, when rear cutting torch cutting, can not get good preheating, groove adds and easily occurs the phenomenons such as gap man-hour.
Above-mentioned cutting machine, gas distributor are prior art, and the technology of not specified (NS) is prior art.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
