Abstract

The utility model belongs to the field of machining equipment and relates to a water cutting device in a circular pipe. The water cutting device in the circular pipe is composed of a small positioning wheel 2, a water cutting head 3, a high pressure generator 4, an automatic sand supply system 5, an X shaft screw rod 6, an X shaft nut 7, a ruler 8, a Z shaft nut 9, a Z shaft screw rod 10, a high pressure pipeline 11, a sand feeding pipeline 12 and a connecting rod 13. When the circular pipe 1 is cut, the X shaft screw rod is firstly moved, the water cutting head 3 is moved into the circular pipe by the Z shaft screw rod, a cutting distance is displayed by an external ruler 8, and a distance from the water cutting head 3 to an inner pipe wall is automatically positioned by pressing the small positioning wheel 2 on a lower pipe wall. After the high pressure generator 4 and the automatic sand supply system 5 are started, a high-pressure water sand mixture can cut the circular pipe 1 through the water cutting head 3.

Description

Water cutter cutting equipment in a kind of pipe

Technical field

The utility model belongs to the machining equipment field, particularly relates to water cutter cutting equipment in a kind of pipe.

Background technology

At present domestic all is directly along the outer round surface cutting during light water jet cutting machine cutting pipe in water cutting industry, and the shortcoming of cutting like this is: after tube wall was severed, the water of high pressure and sand can be got to the inside pipe wall of other one side, and pipe internal surface is wounded.The utility model technology directly reaches cutting head and goes cutting in the pipe, and the inwall of pipe can be damaged, and has solved this problem well.

Summary of the invention

The purpose of the utility model is that design a kind ofly can be deep into the special equipment that cut pipe inside with water cutter cutting head.Water cutter cutting equipment in the pipe is by locating steamboat 2, water cutter cutting head 3, high pressure generator 4, supplying sand system 5, X axial filament bar 6, X axial filament mother 7, scale 8, Z axial filament mother 9, Z axial filament bar 10, pressure piping 11, sand-feeding tube road 12, connecting rod 13 to form automatically.Location steamboat 2 is connected with water cutter cutting head 3 through connecting rod 13; High pressure generator 4 links to each other with water cutter cutting head 3 through pressure piping 11; Automatically supply sand system 5 to link to each other with water cutter cutting head 3 through sand-feeding tube road 12; Scale 8 is contained on the X axial filament female 7, and X axial filament female 7 is enclosed within on the X axial filament bar 6, and Z axial filament female 9 is enclosed within on the Z axial filament bar 10.Above structure constitutes water cutter cutting equipment in the pipe.

The utility model has the advantages that: the ruined defective of inner surface meeting of having managed when having overcome light water jet cutting machine cutting pipe, improved cut quality and yield rate.

The specific embodiment

The purpose of the utility model is achieved in that as shown in Figure 1, and water cutter cutting equipment is by locating steamboat 2, water cutter cutting head 3, high pressure generator 4, supplying sand system 5, X axial filament bar 6, X axial filament mother 7, scale 8, Z axial filament mother 9, Z axial filament bar 10, pressure piping 11, sand-feeding tube road 12, connecting rod 13 to form automatically in a kind of pipe.Location steamboat 2 is connected with water cutter cutting head 3 through connecting rod 13; High pressure generator 4 links to each other with water cutter cutting head 3 through pressure piping 11; Automatically supply sand system 5 to link to each other with water cutter cutting head 3 through sand-feeding tube road 12; Scale 8 is contained on the X axial filament female 7, and X axial filament female 7 is enclosed within on the X axial filament bar 6, and Z axial filament female 9 is enclosed within on the Z axial filament bar 10.

Operation principle:

High pressure generator 4 is the devices that produce high-pressure water, supplies sand system 5 feedwater cutter cutting heads 3 to provide the cutting that mixes with the high pressure water to use sand automatically.Water cutter cutting head under the transmission of X axial filament bar 6, X axial filament female 7 and Z axial filament bar 10, Z axial filament female 9 can about, move up and down.When water cutter cut workpiece, water cutter cutting head 3 optimum distance surperficial apart from cutting member is 2-3mm, the position of tool tip of water cutter cutting head 3 is adjusted to be higher than the least significant end 2-3mm that locatees steamboat 2.Z axial filament bar 10 is when free state;, the weight of X axle and cutting head can slide naturally downwards under driving; When location steamboat 2 touches pipe 1 lower inner wall; Water cutter cutting head 3 is the cutting surface 2-3mm of distance pipe just, has not only guaranteed the optimum position of cutting head apart from the cutting surface, can prevent to hit simultaneously the cutter situation again and take place.When cutting pipe 1, at first mobile X axle, Z axial filament bar move to pipe inside with water cutter cutting head 3, and the cutting distance is shown that by the scale 8 of outside water cutter cutting head 3 is pressed in down on the tube wall by location steamboat 2 to the distance between inner tubal wall and locatees automatically.Start high pressure generator 4 and supply sand system 5 automatically, the water of hyperpressure and sand mix in water cutter cutting head 3, and the water sand mixture of high pressure just can cut pipe 1 through water cutter cutting head 3 and wear, and can guarantee that pipe 1 inner surface can not be destroyed.
