Example Embodiment

[0029] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained in conjunction with specific implementations below.

[0030] Such as figure 1 As shown, the method for manufacturing petroleum oil pipe according to the present invention is characterized in that the method includes the following steps:

[0031] Step 1: Draw out the unrolled material of the cylinder according to the size, and open the welding groove;

[0032] Step 2: Perform rounding processing on the unrolled material under step one on the bending machine;

[0033] Step 3: Weld the groove according to the welding process;

[0034] Step 4: Polish the welded part of the oil pipe in Step 3;

[0035] The plate rolling machine includes a side plate 3 for supporting the overall structure and a waist chute 5 provided on each of the side plates 3. The side plate 3 is fixedly connected by a nut 4 for fixing the ...

Abstract

The invention relates to the field of cold machining equipment, in particular to a manufacturing method of a petroleum oil pipe. A plate rolling machine adopted by the invention comprises a screw, a first support, a side plate, a nut, a sliding groove, vertical plates, roller shafts, a limiting structure, a handle, a limiting block, a pulley, a clamping sleeve, a pin, an anti-skid sleeve, a crank,a first compression roller, a second compression roller, a tight locking nut, bearings, a positioning block, a second support, a feeding plate and a stop dog; according to the method, through the arrangement of the sliding groove in the side plate, the sliding groove is rotationally connected with the first support and the second support through the nut, the vertical plates are arranged at the top end of the side plate, and the vertical plates are arranged two, and the two vertical plates are symmetrically distributed; the roller shafts are rotationally connected with the vertical plates through the bearings, and three roller shafts are arranged; and one ends of the roller shafts are connected with the vertical plates, the clamping sleeve is rotationally connected with the pulley throughthe pin, and the pulley can guide and correct a coiled material. Through the manual rotation of the crank to drive the roller shafts to rotate, a plate which can be conveniently rolled is facilitated,a first pressing roller and a second pressing roller sleeve the roller shafts, and curling of different plates can be facilitated.

Description

technical field [0001] The invention relates to the field of cold processing equipment, in particular to a method for manufacturing petroleum oil pipes. Background technique [0002] At present, oil pipe processing adopts three-roller plate rolling machine, which consists of four steps of steel plate pre-bending (pressure head), centering, rounding and welding. bend. The working principle of the plate rolling machine is to move the work roll through the action of hydraulic pressure, mechanical force and other external forces, so that the plate is bent or rolled into shape. According to the rotation movement and position changes of the work rolls of different shapes, oval parts, arc parts, cylindrical parts and other parts can be processed. [0003] However, the traditional plate rolling machine has a single mechanism and is inconvenient to operate. It cannot work uniformly on coil materials of various specifications, which brings inconvenience, and the coil materials are e...
