Description
The present invention relates to a kind of one-shot forming, cut-out equipment, belong to the flame cutting equipment technical field with propane flammable gas cutting steel pipe.
Gas cutting is that the neutral flame that utilizes oxygen and fuel gas to mix gives heat to ignition temperature with the metal that is cut, pass to the hyperbaric oxygen air-flow in preheating place then, metal is burnt in pure oxygen emit a large amount of heat, and borrow the pressure of hyperbaric oxygen air-flow that the oxide that incision forms is blown away, thereby cutting bulk metal.Gas cutting is the same with welding, occupies critical role on engineering, is widely used in many industrial departments such as metallurgy, building, boats and ships, chemical industry and machine-building, oil exploration exploitation.Domestic present most of industrial trades remain employing with calcium carbide (CaC
2) acetylene gas that produces for raw material and water effect welds or gas cutting, so just need settle the acetylene generator of bulky heaviness at operation field.And because after the steel pipe of conventional cutting cut off, its processing end face was coarse concavo-convex uneven, loss is big, also need just can use through being machined into the groove shape, and operation is many, and efficient is low.
The purpose of this invention is to provide a kind of one-time formed, cutter for steel tubes that processing loss is low, can be installed in the steel pipe's production factory, from the tubulation production line, steel pipe length according to the rules is cut into pieces.Whole cutting process adopts the control method of electromechanical integration, dipping, cut off, technology such as groove moulding processes at one time, and the steel pipe processing loss dropped to bottom line.
Structure diagram of the present invention as shown in Figure 1, it mainly comprises cutter sweep and measurement, control device two parts, cutter sweep is to be equipped with on the mobile platform 2 of turn-screw 4 and drive motors M1 thereof its bottom a stand type support 5 is installed, and two worm gear 8, worm screw 7 and drive motors M2 thereof that can adjust the propane cutting torch 10 of angle, position respectively and the workpiece (steel pipe) 1 that is inserted in is wherein rotated are housed on support 5; Measure, control device then by an end installed steel pipe end surface measurement sensor 9 of platform 2 and steel pipe radially rotating speed and move axially velocity measurement sensor 3 and near the interface interface case 11(RTU of installation this device) and be installed in microcomputer 12(CPU in the control room) form.The input of the output of each sensor and drive motors M1, M2 all is connected with the adaptation module separately that is inserted in 11 li in interface case, and 11 in interface case is connected with microcomputer 12 by cable.
The course of work of the present invention is such: all cutter sweep all is installed on the mobile platform, after the steel pipe of making from pipe production line enters this device, the measuring transducer 3 of rotating speed and point-to-point speed just is close on the outer surface of steel pipe 1 and is gathered measurement, and stepper drive motors M1 can make turn-screw 4 rotate after rotating thereupon, because of leading screw clasp nut 6 is fixed on the ground, thereby mobile platform 2 is moved to the left.After driving stepper motor M2 rotation worm screw 7, worm gear 8 are rotated in a circumferential direction, these two drive motors all receive from the control instruction from computer of interface case input and move.Sensor 3 steel shaft to and radially rotating speed import control interface interface case on the spot, send into the control microcomputer again and handle, calculate the dipping value of steel pipe in real time, and be stored in the database of microcomputer.When steel pipe moves to the position of touching end face detecting sensor 9, promptly entered the actuating range that begins to cut.At this moment, drive stepper motor M1 by the control of interface interface case simultaneously and rotate, mobile platform is moved to left, allow 10 pairs of steel pipes of cutting torch 1 keep axial tracking; Command driven stepper motor M2 rotates simultaneously, makes 10 pairs of steel pipes 1 of cutting torch also keep radially (tangentially) tracking.Microcomputer is also by the flow valve＞size in real time control of cut state of interface case to igniting, air feed＜oxygen and the propane flammable gas of two cutting torches in addition.
Because the present invention adopts the combustible gas of propane flammable gas as cutting torch, and makes angle, the position of two cutting torches all can do to adjust arbitrarily easily, so just can carry out the precision cutting.This is that the metal of otch loss is few because we know that the scarfing quality of propane cutting is much better than to use acetylene, and otch is highly polished (can be reached
3), once cut into V-butt with two cutting torches of certain angle again, just can no longer carry out machining, just a cutting forming.In a word, the present invention has adopted the main control system-microcomputer in the electromechanical integration technology, interface interface case, various sensors match with cutter sweeps such as stepper motor and propane cutting torches, each responsive collecting unit and execution output unit (as air valve, the igniter of stepper motor, cutting torch) etc. all are unified into an organic whole with whole device, under the unified control of microcomputer is coordinated, make the dipping of steel pipe, cut off, groove shaping etc. is once finished, and realizes the advanced cutting technique process that gets twice the result with half the effort.Moreover the expert system software of can packing in the internal memory of control microcomputer is improved its function software thereby update, and realizes optimized operation control.
The present invention compares with the traditional conventional automation cutting equipment or the technology of hand cut steel pipe, has tangible economic technology and superiority.Conventional automation cutting equipment is after steel pipe is cut off, the also machining moulding that will replenish its end face, and the present invention is because of adopting the propane cutting, the precision height, fineness is good, but all one-shot formings of each otch, remove machining processes from, saving of work and time, it is little that the loss of steel pipe is significantly reduced, and the steel pipe pipe material of each scarfing loss is between 2～3 millimeters.Because the present invention adopts sensitive measurement unit and data in real time treatment technology in the electro-mechanical system, carry out the brand-new technology of dipping, tracking cutting and once-forming at random, make the length dimension precision of steel pipe improve greatly, in the steel pipe length dimension that makes it to remain on high-grade grade requires, even steel pipe is strengthened as the competitiveness of commodity, also created facility for the application of steel pipe.Moreover the control centre of this device is a mini-computer, and this machine all has communication interface, can take this to link any all-purpose computer network.So for steel pipe manufactory from now on finishes after the technological transformation, chain of the present invention is gone into control centre of the tube mill network condition of providing convenience.Along with being constructed and put into operation of China several big petrochemical industry base, a large amount of sources of supply of propane flammable gas are also unquestionable.The acetylene gas that replaces calcium carbide to produce with propane still be in the national economy economize on electricity economize one of great conservation measures of coal.Therefore, the present invention uses and will demonstrate great vitality aspect many Technological Economies and the social benefit.
