Abstract
Description
Technical Field
[0001] This invention relates to the field of friction welding technology, and in particular to an automated processing device for friction welding seams based on drill pipe. Background Technology
[0002] Friction welding is a method of welding that utilizes the heat generated by friction between the contact surfaces of workpieces as a heat source, causing the workpieces to undergo plastic deformation under pressure. Under constant or increasing pressure and torque, the relative motion between the welding contact surfaces generates frictional heat and plastic deformation heat in and around the friction surface, raising the temperature in and around the area to a range close to but generally below the melting point. This reduces the material's resistance to deformation, increases its plasticity, and breaks down the oxide film at the interface. Under the action of upsetting pressure, the material undergoes plastic deformation and flow, achieving solid-state welding through molecular diffusion and recrystallization at the interface.
[0003] Friction welding of drill pipes produces weld seams. Traditional single-head or simple cutter head structures are prone to vibration and tool deflection when dealing with high-hardness weld seams, resulting in poor surface finish and rapid tool wear. Furthermore, existing equipment cannot perform roughing and fine grinding of the weld seams in a single process. Moreover, existing devices often use open or simple baffle protection, causing sharp, high-temperature metal chips generated during grinding to fly everywhere, endangering equipment safety and making cleaning difficult. There is a lack of an integrated mechanical structure capable of actively and directionally collecting and initially processing the chips.
[0004] Therefore, an automated processing device for friction welding seams based on drill rods is needed. This device can clamp drill rods of different thicknesses and drive them to rotate, effectively improving equipment utilization. This device can automatically transfer drill rods of different thicknesses and assist their rotation, ensuring smooth processing of drill rod weld seams. This device can achieve coarse processing and fine grinding of weld seams in one integrated process, effectively improving processing efficiency. Summary of the Invention

The electric transfer wheel then operates, driving the drill rod into the housing from the large through hole on the side of the housing. The weld of the drill rod is adjusted to be located between the two U-shaped frames, realizing automatic transfer and adjustment of the drill rod, effectively improving the utilization rate of the equipment.

At the rectangular hole of the corresponding upright plate 210, motor IV 220 is fixedly installed on the support block inside the second auxiliary plate 218, and its motor shaft is fixedly connected to one end of the grinding wheel 219; specifically, when motor IV 220 is started, it drives the grinding wheel 219 to rotate, and the grinding wheel 219 grinds the weld of the drill rod; motor V 221 is fixedly installed on the side of the second bracket 217, and its motor shaft is fixedly connected to the shaft of a cam, which contacts the outer side of the second auxiliary plate 218 and works in cooperation.
[0043] like Figure 2 As shown, the feeding mechanism 1 includes: a bracket 101, a support plate 102, a base plate 103, a cylinder 104, and electric transfer wheels 105; there are two brackets 101, which are fixedly installed in a predetermined area on the ground, and the sides of the brackets 101 are provided with vertical grooves; the protrusions on both sides of the support plate 102 are slidably installed in the vertical grooves on the inner sides of the two brackets 101; the base plate 103 is fixedly installed on the ground; the cylinder body of the cylinder 104 is fixedly installed on the base plate 103, and the piston rod end of the cylinder 104 is fixedly connected to the lower end face of the support plate 102; there are several electric transfer wheels 105, which are equidistantly installed on the upper end face of the support plate 102, and the electric transfer wheels 105 can drive the drill rod located on it to move while assisting the drill rod to rotate on it.
[0044] Working principle: When transferring the drill rod, the drill rod is first placed on the electric transfer wheel 105 by external equipment. The cylinder 104 is started, pushing the support plate 102 to move up and down, so that the drill rod is aligned with the center of the large through hole on the side of the housing 201. Then, the electric transfer wheel 105 works, driving the drill rod to enter the housing 201 from the large through hole on the side of the housing 201, and adjusting the weld of the drill rod to be located between the two U-shaped frames 209. Then, motor II 208 starts, driving the limit ring 207 to rotate. The limit ring 207 drives the four clamping rods 206 to move inward simultaneously, so that the inner ends of the four clamping rods 206 clamp the drill rod. When the four clamping rods 206 move inward, the slots on the side of the clamping rods 206 engage with the corresponding limiting rods on the side of the vertical plate 210 and move inward simultaneously, so that the distance between the inner ends of the cutting tool 216 and the grinding wheel 219 and the drill rod is always the same. Then, the weld of the drill rod is roughened. Motor III 215 is started, which drives the cam on its shaft to rotate. The cam pushes the first auxiliary plate 214 to move inward. The spring on the inner side of the first auxiliary plate 214 is compressed. The first auxiliary plate 214 pushes the cutting tool 216 to contact the drill rod. Then, motor I 205 is started, which drives the ring frame 204 to rotate. The ring frame 204 drives the four clamping rods 206 to clamp the drill rod and rotate. The cutting tool 216 roughens the weld of the drill rod. At this time, several electric transfer wheels 105 play an auxiliary rotation role for the drill rod. When grinding the weld, firstly, motor III 215 drives the cam on its shaft to rotate and return to its original position. The spring on the first auxiliary plate 214 releases its elastic force and pushes the first auxiliary plate 214 to move and return to its original position. The first auxiliary plate 214 drives the cutting tool 216 to move and return to its original position. Then, motor V 221 starts and drives the cam on its shaft to push the second auxiliary plate 218 to move inward. The spring on the inner side of the second auxiliary plate 218 is compressed. The second auxiliary plate 218 drives the grinding wheel 219 to contact the weld of the drill rod. Then, motor IV 220 starts and drives the grinding wheel 219 to rotate. The grinding wheel 219 grinds the weld of the drill rod. The ring frame 204 still drives the four clamping rods 206 to hold the drill rod and rotate, so as to achieve all-round grinding of the weld of the drill rod. In addition, during the treatment of the drill pipe weld, two nozzles 212 spray water outward to cool the weld simultaneously. The wastewater generated flows into the collection shell 202 through the transition shell 203 for collection, preventing wastewater from splashing while collecting and treating the wastewater, effectively preventing wastewater from polluting the environment.
