A welding device for producing pipe elbows

Abstract

This utility model discloses a welding device for producing pipe elbows, belonging to the field of pipe processing. It includes a base, a rotating clamping mechanism on the top of the base, and a welding mechanism on one side of the rotating clamping mechanism. The welding mechanism includes an electric push rod, a horizontal plate fixed to the bottom of the electric push rod, a welding torch fixed to the bottom of the horizontal plate, and a detection mechanism on one side of the welding torch. The detection mechanism includes a mounting frame, an abutment wheel rotatably connected to the inner walls of the mounting frame, a sliding rod fixedly connected to the top of the mounting frame, a limit plate fixedly connected to the top of the sliding rod, a spring fixedly connected between the mounting frame and the horizontal plate, and a proximity switch fixedly connected to the bottom of the limit plate. The beneficial effect is that during the downward movement of the welding torch driven by the horizontal plate, the abutment wheel first abuts against the pipe wall. As the horizontal plate continues to move downward, the distance between the horizontal plate and the limit plate changes. When a set value is reached, the welding torch stops moving, thereby ensuring a suitable height between the welding torch and the pipe wall.

Description

Technical Field

[0001] This utility model relates to the field of pipe processing, and in particular to a welding device for producing pipe elbows. Background Technology

[0002] In the process of pipe processing, in order to meet the requirements, two straight pipes are usually connected by pipe elbows. During the processing, welding equipment is required to weld the pipe elbows.

[0003] A search of Chinese Patent Publication No. CN222307761U reveals a large-scale automated welding machine for elbows, comprising a base and a slide groove. The slide groove is embedded on the surface of the base, and a slider is provided inside the slide groove. The slider and the slide groove are slidably connected. A fixed plate is provided on the top of the slider, and an mounting plate is provided on one side of the fixed plate. The mounting plate and the fixed plate are rotatably connected. An adjustment groove is embedded on the surface of the mounting plate, and a locking plate is provided inside the adjustment groove. The locking plate and the adjustment groove are slidably connected. A first bidirectional threaded rod is provided inside the adjustment groove, and the first bidirectional threaded rod and the locking plate are connected by threads. An adjustment rod is provided at one end of the first bidirectional threaded rod. There are two locking plates. A fixed frame is provided on one side of the base, and the fixed frame is fixedly connected to the base. A guide rail is embedded at the bottom of the fixed frame, and a guide block is provided inside the guide rail. The guide block and the guide rail are slidably connected. An electric telescopic rod is provided at the bottom of the guide block, and a welding torch is provided at the output end of the electric telescopic rod.

[0004] In existing welding equipment, although the height of the welding torch can be adjusted by an electric push rod, it is difficult to control the distance between the welding torch and the pipe wall when dealing with pipe fittings and elbows of different sizes. Too far or too close a distance will affect the welding quality. Utility Model Content

[0005] The purpose of this utility model is to provide a welding device for the production of pipe elbows in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

The rotating clamping mechanism includes a support seat 201 bolted to the top of the base 1. An arc-shaped groove is provided on the top of the support seat 201. A turntable 202 is rotatably connected in the arc-shaped groove. A through hole is provided in the middle of the turntable 202. Multiple sets of clamping assemblies are arranged circumferentially on the side of the turntable 202 near the welding torch 304. The clamping assembly includes a first hydraulic cylinder 203 fixedly connected to the side wall of the turntable 202. A clamping plate 204 is fixedly connected to the output end of the first hydraulic cylinder 203. Multiple first hydraulic cylinders 203 are controlled by a switch. A V-shaped groove is provided on the side of the clamping plate 204 near the axis of the turntable 202.

[0027] The rotary clamping mechanism also includes a rotary assembly for driving the turntable 202 to rotate. The rotary assembly includes a gear ring 205 fixedly connected to the side of the turntable 202 away from the clamping assembly. A rotary motor 206 is bolted to the side wall of the support base 201. A gear 207 is fixedly connected to the output end of the rotary motor 206. The gear 207 meshes with the gear ring 205. When the rotary motor 206 is started, the rotary motor 206 drives the gear 207 to rotate. The gear 207 meshes with the gear ring 205, thereby driving the gear ring 205 to drive the turntable 202 to rotate.

[0028] A welding mechanism is provided on one side of the rotating clamping mechanism. The welding mechanism includes an electric push rod 302, a horizontal plate 303 is fixedly connected to the bottom of the electric push rod 302, and a welding torch 304 is fixedly connected to the bottom of the horizontal plate 303. The welding mechanism also includes a bracket 301. A sliding groove is provided on the top of the base 1. The bracket 301 is slidably connected in the sliding groove. The electric push rod 302 is fixedly connected to the bracket 301. A power component that drives the bracket 301 to move is provided in the sliding groove. The power component includes a second hydraulic cylinder 305. The second hydraulic cylinder 305 is fixedly connected in the sliding groove. The bracket 301 is fixedly connected to the output end of the second hydraulic cylinder 305.

[0029] A detection mechanism is provided on one side of the welding torch 304. The detection mechanism includes a mounting frame 401. An abutment wheel 402 is rotatably connected between the inner walls of the mounting frame 401. A slide rod 403 is fixedly connected to the top of the mounting frame 401. The top of the slide rod 403 extends out of the horizontal plate 303 and is fixedly connected to a limit plate 404. A spring 405 is fixedly connected between the mounting frame 401 and the horizontal plate 303. The spring 405 is wrapped around the outer periphery of the slide rod 403. A proximity switch 406 is fixedly connected to the bottom of the limit plate 404. When the proximity switch 406 reaches the set value, the electric push rod 302 closes.

[0030] Working principle: In use, one end of the pipe elbow is inserted into the through hole in the center of the turntable 202. The first hydraulic cylinder 203 is activated, and the pipe elbow is clamped and fixed by multiple sets of clamping plates 204. Then, the electric push rod 302 is controlled to move the horizontal plate 303 and the welding torch 304 downward. During the downward movement of the welding torch 304 driven by the horizontal plate 303, the abutment wheel 402 first abuts against the pipe wall. As the horizontal plate 303 continues to move downward, the distance between the horizontal plate 303 and the limiting plate 404 changes. When the set value is reached, the electric push rod 302 closes, and the welding torch 304 stops. The welding torch 304 is moved to ensure a suitable height between itself and the pipe wall. Welding of the pre-fixed pipe elbow is then performed using the welding torch 304. Simultaneously with starting the welding torch 304, the rotary motor 206 is activated. The rotary motor 206 drives the gear 207 to rotate. The gear 207 meshes with the gear ring 205, which in turn drives the gear ring 205 to rotate the turntable 202. The turntable 202 then rotates the clamped pipe elbow, facilitating 360-degree full welding. The position of the support 301 can be adjusted according to the length of the pipe elbow using the second hydraulic cylinder 305.
