Problems solved by technology

[0003] However, in the actual heat treatment process, due to the large diameter of the oil and gas transportation pipes, and most of the materials are made of stainless steel, it is not easy to enter the heat treatment furnace due to the large weight during the heat treatment process.
Traditionally, manual lifting and unloading is not only time-consuming and labor-intensive, especially when it is close to the furnace door, due to the high temperature in the furnace, the flame will cause burns to the human body, and even production accidents caused by pipes rolling down are not uncommon.
In addition, some factories use manipulators to complete the feeding and retrieving process of pipe heat treatment, but the manipulator needs more steps to complete the feeding and retrieving process, which is inefficient, and the purchase of manipulator equipment for small enterprises is expensive, resulting in cost expansion

Embodiment 1

[0034] Such as Figure 1 to Figure 5 As shown, the table-type adjustable pipe material feeding and reclaiming machine described in the present invention includes a workbench 1 and a pillar 2, the workbench 1 is fixed on the upper part of the pillar 2, and a slide rail 3 is arranged on the table of the workbench 1 , the slide rail 3 is provided with a distance scale 19, the inside of the slide rail 3 is provided with a groove 16, the workbench 1 is provided with two lead screw systems, and the bottom of the two lead screw systems is provided with a convex Rail 17, the screw system is symmetrical along the vertical direction of the workbench 1, the two screw systems can reciprocate along the slide rail 3, the screw system includes a motor 5, a screw 11, a feeding seat 13, a limiter Bit spring 12, pressure sensor 18, feeding plate 6, clamping plate 7, described lead screw 11 is in the middle of inner guide plate 14 and outer guide plate 15, wherein lead screw 11 is driven by moto...

Embodiment 2

[0043] The following uses the pipe material feeding and retrieving process as an example to specifically illustrate the processing process of the pipe material by using a desktop adjustable pipe material feeding and reclaiming machine described in Embodiment 1:

[0044] First, the diameter D of the pipe is measured, and it can be known that the radius of the pipe is R=D / 2. Then start the hydraulic system, the hydraulic pump 8 drives the hydraulic rod 10 to push the lead screw system, and through the reference distance scale 19, when the lead screw system moves along the slide rail 3 Finally, after arriving at the predetermined station (where L is the initial distance between the two lead screw systems), close the valve 8 of the hydraulic pump. At this time, the hydraulic system stops working, and the hydraulic rod stops moving. After being in the triangular guide rail 4, start the motor 5, the motor 5 starts to enter the forward rotation state, the lead screw 11 connected wit...

Abstract

The invention relates to a feeding and fetching machine, in particular to a feeding and fetching machine in the process of heat treatment of pipes and a treatment method of the pipes. The feeding and fetching machine comprises a worktable and supporting columns; the worktable is fixed to the upper portions of the supporting columns; sliding rails are arranged on the table surface of the worktable, distance scales are arranged on the sliding rails, and grooves are formed in the sliding rails; two lead screw systems which are symmetrical along the vertical direction of the worktable and can reciprocate along the sliding rails are arranged on the worktable, and convex rails embedded in and matched with the grooves are arranged on the bottom of the lead screw systems; and two hydraulic systems which are symmetrical along the vertical direction of the worktable are arranged on the worktable. The pipe feeding and fetching machine in the process of heating treatment is reasonable in structure design, high in degree of automation, strong in safety and simple in operation, can carry out feeding of pipes with different diameters, can achieve the purpose of fetching after heating treatment, improves the efficiency of heating treatment of the pipes, and thereby providing reliable basis for the application of the pipes in the field of engineering.

Description

technical field [0001] The invention relates to a feeding and reclaiming machine, in particular to a desktop adjustable pipe feeding and reclaiming machine and a pipe processing method. Background technique [0002] With the large-scale construction and development of domestic oil and gas fields, the demand for oil and gas transportation pipes has increased year by year in recent years, and the processing quality of pipes has also been put on the agenda. The main processing process of the pipe includes heating, piercing, rolling, sizing, heat treatment, etc. The heat treatment process can improve the internal structure of the pipe, and play a key role in improving the mechanical properties of the pipe and prolonging its service life. [0003] However, in the actual heat treatment process, due to the large diameter of the oil and gas transportation pipes, and most of the materials are made of stainless steel, the pipes are not easy to enter the heat treatment furnace due to t...
