Abstract

The utility model provides a hydraulic cold flaring machine belonging to a steel tube processing machine tool. The hydraulic cold flaring machine is provided with a pedestal; a flaring hydraulic oil cylinder is arranged on the pedestal; the outer end of a telescopic arm of the flaring hydraulic oil cylinder is connected with a flaring die having a taper-shaped end; the front of the flaring die is provided with a clamp holder fixed on the pedestal; a lower clamping groove body is arranged in the clamp holder; an upper clamping groove body is arranged above the lower clamping groove body; the lower end of the telescopic arm of a clamping oil cylinder arranged on the pedestal is connected with the upper clamping groove body into a whole. The flaring machine accomplishes the flaring operation under the drive of the hydraulic oil cylinder without needing a heating device; the structure of the hydraulic cold flaring machine is simple, the production cost is low, the use is highly convenient, and the work efficiency is high.

Description

The cold pipe-expanding machine of hydraulic pressure

Technical field

The utility model provides a kind of steel pipe machining machine and tool, especially a kind of pipe-expanding machine.

Background technology

At present, in actual production process, need to enlarge wall thickness, connect to realize the socket between the steel pipe than the port diameter that approaches as the steel pipe of 1-5 millimeter.The seal of oil resistant, acid and alkali-resistance of packing between the steel pipe of junction during connection is realized fixing, and does not take welding connecting mode.In the pipeline that this connected mode connects into, can carry out various measurements or observation to the tube circumference ambient conditions.The facility of present expansion steel pipe port diameter (abbreviation enlarging) adopt hot expansion mode usually, need heater, the implement structure complexity, and the cost height, inefficiency, the convenience of use is poor.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of hydraulic pressure cold pipe-expanding machine, to simplify the internal structure of an organization the convenience that raising is used.

The utility model is to realize like this, the cold pipe-expanding machine of hydraulic pressure, it has base, the enlarging hydraulic jack is installed above the base, the telescopic arm outer end of enlarging hydraulic jack is connected with the tapered enlarging mould in end, and enlarging mould the place ahead has clamping fixture seat to be fixed on the base, and the lower fastening groove body is arranged in the clamping fixture seat, there is the upper fastening groove body lower fastening groove body top, and the telescopic arm lower end and the upper fastening groove body of the clamping cylinder that clamping fixture seat is installed above link together.

Adopt the pipe-expanding machine of said structure, finish the enlarging operation under the drive of hydraulic jack, do not need heater, simple in structure, cost is low, the convenience height of use, high efficiency.

Description of drawings

Fig. 1 is the schematic diagram of the utility model structure.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the connected mode schematic diagram of the steel pipe after the enlarging.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing further specifies structure of the present utility model and using method.

As shown in drawings, the cold pipe-expanding machine of the hydraulic pressure of the utility model, it has base 1, enlarging hydraulic jack 8 is installed above the base, the telescopic arm outer end of enlarging hydraulic jack is connected with the tapered enlarging mould 6 in end, and enlarging mould the place ahead has clamping fixture seat 5 to be fixed on the base, and lower fastening groove body 2 is arranged in the clamping fixture seat, there is upper fastening groove body 3 lower fastening groove body top, and the telescopic arm lower end and the upper fastening groove body of the clamping cylinder 4 that clamping fixture seat is installed above link together.

Obviously, the profile of enlarging mould is a cylinder, and its front end is tapered so that insert and to treat in the enlarging steel pipe port.Each hydraulic jack is connected with oil pump.The upper surface of the lower surface of upper fastening groove body, lower fastening groove body has respectively and treats the corresponding groove 9 of enlarging outer diameter of steel pipes, and when clamping steel pipe, two grooves are pressed close to steel pipe.Enlarging mould 6 can link together by the telescopic arm outer end of ring flange 7 with the enlarging hydraulic jack.The axis of the axis of the groove on the lower fastening groove body and enlarging mould should be same straight line.

During use, the external diameter of the steel pipe of enlarging is determined the diameter of the groove on the upper and lower clip slot body as required, and both should be identical.The internal diameter of the steel pipe after the enlarging is as required determined the external diameter of enlarging mould, and both should be identical.To treat that the enlarging steel pipe is placed between the upper and lower clip slot body, steel pipe treat flared end towards the enlarging mould, and stretch out certain-length (deciding) according to enlarging length.Drive the upper fastening groove body by clamping cylinder then and move down, clamp steel pipe.Drive the enlarging mould by the enlarging hydraulic jack again and move to the steel pipe direction, its front end is inserted in the steel pipe port, the enlarging mould is moved further and the steel pipe port will be strutted, and enlarges its internal diameter.The length of flared section can be the 20-200 millimeter.

For alleviating the friction between enlarging mould cylindrical and the steel pipe inwall, can be before the enlarging in enlarging mold outer surface coating lubricating oil.

On hydraulic system, can establish overflow valve, to set rated oil pressure and to adjust oil pressure.

As shown in Figure 3, the steel pipe 11 after the enlarging can be realized fixing by seal 10 when adjacent another steel pipe 12 is connected.
