Description
Technical Field
[0001] The utility model belongs to the technical field of pressure pipe production, and in particular relates to a pushing device for connecting and producing steel-plastic composite pressure pipes. Background Art
[0002] At present, in the production process of steel-plastic composite pressure pipes, when argon arc butt welding is performed, two sections of steel pipes are often pushed together manually and then manually welded with a welding gun. This is not only cumbersome, inconvenient, time-consuming and labor-intensive, but also prone to misalignment at the joint, which leads to reduced welding quality or even welding failure, and needs to be improved. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide a pushing device for steel-plastic composite pressure pipe connection production, which can achieve effective clamping and fixing of steel pipes and automatic and accurate pushing and welding to solve the above problems.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a pushing device for connecting steel-plastic composite pressure pipes in production, comprising an operating table, a first guide rail is fixedly arranged horizontally on the top of the operating table along the left and right directions, a first electric slider is slidably arranged on both the left and right sides of the first guide rail, a support plate is fixedly arranged horizontally on the top of the first electric slider, a second guide rail is fixedly arranged horizontally on the top of the support plate along the left and right directions, two second electric sliders are slidably arranged on the second guide rail, a three-claw chuck is fixedly arranged on the top of the second electric slider, and a first electric slider is slidably arranged on the center of the first guide rail. A third electric slider is provided, a supporting ring is fixedly provided on the top of the third electric slider, an annular guide rail is fixedly provided on one side of the supporting ring, the annular guide rail is coaxially arranged with the three-jaw chuck, a fourth electric slider is slidably provided on the annular guide rail, an electric push rod is vertically fixedly provided on the side of the fourth electric slider away from the annular guide rail, the telescopic end of the electric push rod faces downward and is fixedly connected to a lifting plate, a welding gun and an argon gas pipe are respectively penetrated and fixed on the left and right sides of the lifting plate, the top of the argon gas pipe is connected to an argon gas source through a hose, and the bottom end is fixedly connected to a nozzle facing the welding gun.
[0005] Preferably, the operating table and the support plate are both made of foam aluminum.
[0006] Preferably, legs are vertically fixed at the four corners of the bottom of the operating table, and support pads are fixed at the bottom ends of the legs.
[0007] Preferably, hydraulic cylinders are vertically fixed on both front and rear ends of the left and right sides of the operating table, and the piston rods of the hydraulic cylinders face downward and are connected to universal wheels.
[0008] The beneficial effect of the utility model is that when two sections of steel pipes are subjected to argon arc butt welding, the two sections of steel pipes can be clamped and fixed first. Specifically, when the steel pipe is short, the steel pipe can be directly inserted into the center hole of the three-jaw chuck close to the support ring, and then the corresponding three-jaw chuck can be used to clamp and fix the welding end of the steel pipe. When the steel pipe is long, the steel pipe can be inserted into the center hole of two three-jaw chucks on the same support plate, and the distance between the two three-jaw chucks on the same support plate can be flexibly adjusted by the second electric slider, and then the two ends of the steel pipe can be clamped and fixed by the jaws on the two three-jaw chucks. In this way, the stability of the clamping is higher, and the subsequent beating and dislocation during welding can be avoided. After the two sections of steel pipes are clamped, the two first electric sliders are operated to drive the two support plates to move relative to each other until the welding ends of the two sections of steel pipes are butted together, and the automatic push-to-butt connection of the steel pipes can be completed. Then, the third electric slider is operated to flexibly adjust the horizontal position of the welding gun so that the welding gun is aligned with the butt joint of the two sections of steel pipes. Then, the electric push rod moves to extend its piston rod, and the height of the welding gun is flexibly adjusted to make the distance between the welding gun and the steel pipe appropriate. After that, the fourth electric slider moves to drive the welding gun to rotate as a whole. At the same time, argon gas is ejected from the argon gas pipe and nozzle, and the current released by the welding gun breaks down the argon gas, which can cooperate to achieve argon arc welding at the butt joint of the steel pipe. In this way, the stable clamping and fixing of steel pipes of different lengths, automatic pushing for butt jointing, and automatic rotation welding can be achieved. There is no need to manually push the steel pipes for butt jointing and welding. The overall operation is simpler, more convenient, time-saving and labor-saving, and can more effectively avoid butt joint dislocation. The overall butt welding quality is higher and more practical.

DETAILED DESCRIPTION
[0012] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0014] When performing argon arc butt welding on two sections of steel pipes, the two sections of steel pipes can be clamped and fixed first. Specifically, when the steel pipe is short, the steel pipe can be directly inserted into the center hole of the three-jaw chuck 7 near the support ring 9, and then the corresponding three-jaw chuck 7 can be used to clamp and fix the welding end of the steel pipe. When the steel pipe is long, the steel pipe can be inserted into the center hole of two three-jaw chucks 7 on the same support plate 4, and the distance between the two three-jaw chucks 7 on the same support plate 4 can be flexibly adjusted by the second electric slider 6, and then the two ends of the steel pipe can be clamped and fixed by the jaws on the two three-jaw chucks 7. In this way, the stability of the clamping is higher, and the subsequent beating and dislocation during welding can be avoided. After the two sections of steel pipes are clamped, the two first electric sliders 3 are operated to drive the two support plates 4 to move relative to each other until the welding ends of the two sections of steel pipes are butted together, and the automatic push-to-butt connection of the steel pipes can be completed. Next, the third electric slider 8 is operated to flexibly adjust the horizontal position of the welding gun 14 so that the welding gun 14 is aligned with the joint of the two sections of steel pipes. Then, the electric push rod 12 is actuated to extend its piston rod, and the height of the welding gun 14 is flexibly adjusted so that the distance between the welding gun 14 and the steel pipe is appropriate. After that, the fourth electric slider 11 is actuated to drive the welding gun 14 to rotate as a whole for one circle. At the same time, argon gas is ejected from the argon gas pipe 15 and the nozzle 17, and the current is released through the welding gun 14 to break through the argon gas, so as to cooperate to achieve argon arc welding at the joint of the steel pipe. In this way, the stable clamping and fixing of steel pipes of different lengths, the automatic pushing and docking, and the automatic rotation welding can be achieved, without the need for manual pushing and docking of steel pipes and welding. The overall operation is simpler, more convenient, time-saving and labor-saving, and the docking dislocation can be more effectively avoided. The overall welding quality is higher and more practical. The first guide rail 2, the first electric slider 3, the second guide rail 5, the second electric slider 6, the three-jaw chuck 7, the third electric slider 8, the annular guide rail 10, the fourth electric slider 11, the electric push rod 12, the welding gun 14 and the nozzle 18 can all adopt the existing technology.
[0015] In this embodiment, the operating table 1 and the support plate 4 are both made of foamed aluminum. Foamed aluminum is an existing material with good damping and shock-absorbing properties, which can effectively buffer and absorb shock, and is more conducive to ensuring the smooth progress of the push welding operation.
[0016] In this embodiment, legs 18 are vertically fixed at the four corners of the bottom of the operating table 1, and support pads 19 are fixed at the bottom ends of the legs 18 to support and fix the entire welding equipment, which is more practical.
[0017] In this embodiment, hydraulic cylinders 20 are vertically fixed on the front and rear ends of the left and right sides of the operating table 1. The piston rod of the hydraulic cylinder 20 faces downward and is connected to a universal wheel 21. In actual use, when the position of the entire machine needs to be changed, it is only necessary to operate the hydraulic cylinder 20 to extend its piston rod, drive the universal wheel 21 to move downward, until the universal wheel 21 is placed on the ground and the support pad 19 is suspended in the air. The entire device can be flexibly moved through the cooperation of four groups of universal wheels 21, which is more convenient for quickly moving and adjusting the entire device into place according to the actual use scenario. After adjustment, it is only necessary to operate the hydraulic cylinder 20 again to retract its piston rod, drive the universal wheel 21 to move up and be suspended in the air, and place the support pad 19 back on the ground. It is more convenient and flexible to use, saves time and effort, and can better ensure the practicality and humanization of the entire device.
[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
