Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a socket steel pipe processing device. Background Technology

[0002] When undertaking steel pipe projects, it is necessary to expand the diameter and groove the steel pipe. Expansion is a method in which the material is subjected to tensile stress under the action of a punch, and is stretched and deformed along the circumference.

[0003] Currently, domestic production of socket steel pipes generally uses a method of cold expansion and groove forming simultaneously. Two machines are arranged in a staggered manner, with one machine used for expansion and grooving of the socket end and the other for expansion, grooving, and pressing of the spigot end. However, this method is prone to causing cracking of the steel pipe, affecting the yield and product quality. The equipment occupies too much space, and it is impossible to fix and limit the steel pipe when expanding its diameter, resulting in poor stability and affecting the forming effect.

[0004] Therefore, it is necessary to provide a new processing device for socket steel pipes to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a socket steel pipe processing device includes a base 1, and further includes: a fixing member 2 for fixing the steel pipe, two sets of first cylinders 3 installed on the top of the base 1, a baffle 4 fixed to the piston rod of the first cylinder 3, an expansion mold 5 for expanding the diameter of the steel pipe, a groove 6 for facilitating the movement of the expansion mold 5, a support seat 7 fixed to one side of the base 1, and a grooving assembly 8 for grooving the steel pipe; the grooving assembly 8 includes a support frame 81 for improving the stability of grooving, a driving member 82 for driving the steel pipe to rotate, and a grooving member 83 for grooving the steel pipe.

[0023] refer to Figure 1 and Figure 2 As shown, the fixing component 2 includes a fixing frame 21 for fixing the steel pipe, a placement frame 22 for placing the steel pipe, and a first motor 23 installed on the top of the fixing frame 21; the fixing component 2 also includes a threaded rod 24 fixed to the output end of the first motor 23, and a clamping frame 25 for clamping the steel pipe; the fixing component 2 also includes connecting plates 26 fixed on both sides of the clamping frame 25, anti-slip pads 27 to prevent the steel pipe from loosening, and a limiting rod 28 to limit the connection plate 26; the threaded rod 24 is threadedly connected to the inside of the connecting plate 26, and the limiting rod 28 is slidably connected to another set of connecting plates 26. The first motor 23 drives the threaded rod 24 to rotate, causing the connecting plate 26 to move the clamping frame 25, causing the other set of connecting plates 26 to slide outside the limiting rod 28, causing the clamping frame 25 to move vertically up and down, so that the clamping frame 25 clamps and fixes the steel pipe inside the placement frame 22, improving the stability during subsequent diameter expansion, and preventing the steel pipe from slipping off through the anti-slip pads 27.

[0024] refer to Figure 3 and Figure 4As shown, the driving component 82 includes a second motor 821 mounted on one side of the support frame 81, a rotating rod 822 fixed to the output end of the second motor 821, and a pressure roller 823 fixed to one end of the rotating rod 822; the grooving component 83 includes a fixed seat 831 fixed inside the support frame 81, and a second cylinder 832 fixed inside the fixed seat 831; the grooving component 83 also includes a fixing block 833 fixed to the piston rod of the second cylinder 832, and a guide rod 8 for limiting the position of the fixing block 833. 36; The grooving component 83 also includes a mounting plate 834 fixed to one side of the fixing block 833, and a grooving mold 835 for grooving the steel pipe; the expanded diameter steel pipe spigot is clamped on the outside of the pressure roller 823, the second cylinder 832 is started to drive the fixing block 833 and the mounting plate 834 to move downward, so that the grooving mold 835 contacts the steel pipe to groove the steel pipe, and the second motor 821 drives the rotating rod 822 to rotate, so that the pressure roller 823 drives the steel pipe to rotate, and performs annular grooving on the steel pipe.

[0025] Working principle: When using this device, the steel pipe is placed on the placement frame 22. The first motor 23 is started to drive the threaded rod 24 to rotate, causing the connecting plate 26 to move the clamping frame 25. This causes another set of connecting plates 26 to slide outside the limiting rod 28, allowing the clamping frame 25 to move vertically up and down, clamping and fixing the steel pipe inside the placement frame 22, improving stability during subsequent diameter expansion. The anti-slip pad 27 prevents the steel pipe from slipping. Then, the two sets of first cylinders 3 are started to move the baffle 4 and the diameter expansion mold 5, allowing the two sets of diameter expansion molds 5 to enter the steel pipe, causing the steel pipe to begin to expand, expanding the diameter of the steel pipe socket and spigot. The diameter of the expanded pipe is larger than that of the mold. The diameter of each steel pipe is about 10mm larger than the previous one. After expansion, the pipes are the same size. Once completed, the first motor 23 is started, which moves the clamping frame 25 upward to remove the steel pipe. The expanded steel pipe end is then clamped on the outside of the pressure roller 823. The second cylinder 832 is started, which moves the fixing block 833 and the mounting plate 834 downward to make the grooving mold 835 contact the steel pipe to groove it. The second motor 821 drives the rotating rod 822 to rotate, which makes the pressure roller 823 rotate the steel pipe to groove it in a ring. One set of grooving mold 835 can groove pipes with diameters between 529mm and 1620mm. The wall thickness can be designed up to 12mm according to the order requirements. The grooving size is the same and does not need to be changed.
