[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, the welding device for producing a chemical container barrel assembly drives the bidirectional screw to rotate by starting the opening and closing motor, and the bidirectional screw drives the two sealing door plates to move away from each other through the thread transmission with the two connecting seats and under the guidance of the T-shaped guide rail, and the barrel components to be welded are placed in the two positioning mechanisms in turn, and the rotating ring is driven to rotate by starting the cylinder. The rotating ring drives multiple slides to approach each other through the cooperation of the arc guide groove and the connecting column, so that the clamping plate abuts against the outside of the workpiece to achieve clamping and fixing, and then the fifth electric push rod is started to drive the two positioning mechanisms to approach each other to achieve splicing of the barrel components, thereby ensuring fast and accurate docking and avoiding deviation;

[0026] 2. In the present invention, a welding device for producing a chemical container barrel assembly is described. By starting the opening and closing motor to drive the two sealing plates to approach each other, after the placement port is closed, the vacuum pump is started to extract the air in the welding box through the exhaust pipe, and the vacuum degree in the welding gun box is monitored by the pressure gauge. When the vacuum degree reaches the requirement, the vacuum pump is controlled to stop and the control valve is started to introduce inert gas into the welding box through the inert gas introduction pipe. The use of inert gas can reduce defects such as pores and slag inclusions in the welding process, improve the density and uniformity of the weld, and the inert gas forms a protective layer as a physical barrier to prevent oxygen and other possible pollutants in the air from contacting the molten metal.

[0027] 3. In the present invention, the welding device for producing a chemical container cylinder assembly is described. By starting the annular electromagnetic heater, the electromagnetic controller converts the externally supplied alternating current into a high-frequency current. When the high-frequency current passes through the induction coil, an alternating magnetic field is generated, and countless small eddy currents are generated in the cylinder. These eddy currents make the cylinder itself heat up at a high speed, thereby realizing the preheating of the cylinder, reducing the hardening degree of the weld and the heat-affected zone, and improving the crack resistance of the welded joint. The preheating can reduce the temperature difference between the welded workpieces in the welding area, reduce the welding stress, and help avoid the generation of welding cracks.

[0028] 4. In the present invention, the welding device for producing a chemical container cylinder assembly drives the welding frame and the upper welding gun to move left and right by starting the third electric push rod, and drives the movable frame and the lower welding gun to move left and right by starting the fourth electric push rod, so that the two welding guns are aligned with the splicing position, and then the first electric push rod is started to drive the two mounting plates to approach each other, so that the two abutment wheels abut against the inner and outer walls of the cylinder respectively, and then the two welding guns are started to achieve welding on both sides of the cylinder, and the driving motor is started to drive the driving gear to rotate, and the driving gear drives the arc seat to perform circular motion along the fixed ring through meshing with the inner gear ring, and the rotating motor is started to drive the mounting plate to rotate, so that the two welding guns can be driven to perform circumferential remote motion, so as to achieve automatic welding of different positions;

[0029] 5. In the present invention, the welding device for producing a chemical container cylinder assembly, during the welding process, the two mounting plates perform circular motion, so that they abut against the fitting cylinder to roll, and drive the active bevel gear to rotate synchronously through the rotating shaft, the active bevel gear drives the vertical shaft and the bending rod to rotate through the engagement with the driven bevel gear, the bending rod drives the connecting plate and the counterweight to perform circular motion, so that the two connecting plates move away from each other under the centrifugal force of the counterweight, and the two ends of the bending rod are inclined, so that the two connecting plates move vertically while moving away from each other, and The lifting plate is driven to move vertically by the action of the horizontal rail and the disc, thereby compressing the compression spring and squeezing the varistor. Since the varistor is connected in series with the welding gun, the power of the welding gun is correspondingly increased, and the greater the rotation speed of the abutment wheel, the greater the power of the welding gun, so that the power of the welding gun is linearly related to the moving linear speed of the welding gun relative to the workpiece. When the diameter of the cylinder to be welded increases and the speed of the driving motor and the rotating motor increases, the moving linear speed of the welding gun relative to the workpiece increases, so that the corresponding power of the welding gun is greater, so as to ensure uniform and high-quality welding;

[0030] 6. In the present invention, the welding device for producing a chemical container cylinder assembly, before welding, needs to connect the two conduits to the water supply pipe and the drainage pipe respectively, when the abutment wheel rotates to drive the lifting vertical movement, the gate plate moves synchronously, so that the through hole on the gate plate is connected with the cooling channel, water directly flows into the cooling channel through one of the conduits, passes through the annular cooling cavity and is discharged from the other conduit, during which the welding gun is cooled by water, and when the abutment wheel speed increases and the welding gun power increases, the downward movement distance of the gate plate will increase, so that the conduction area between the through hole and the cooling channel is increased, thereby increasing the water flow rate, so as to improve the cooling effect and avoid overheating of the welding gun when running at high power;

[0031] 7. In the present invention, the welding device for producing a chemical container cylinder assembly drives the lower plate and the upper plate to move up and down by starting the second electric push rod, so that the rotating wheel abuts against the outer side of the cylinder, and then the mounting plate and the arc seat rotate to drive the two flatness detection mechanisms to perform circular motion. When the rotating wheel contacts the weld, the weld pushes the upper plate to be close to the lower plate by abutting against the rotating wheel, and squeezes the connecting spring. The pressure of the connecting spring is monitored by the pressure sensor, and the pressure limit value and the variation variance are calculated by the control panel, so as to judge whether the weld meets the requirements;

[0032] 8. In the present invention, the welding device for producing a chemical container barrel assembly, after welding is completed, the third electric push rod is started to drive the welding frame to move horizontally, so that the annular electromagnetic heater is located at the periphery of the weld, and the annular electromagnetic heater is started to achieve heat preservation treatment of the weld, which can evenly reduce the temperature of the welding area and avoid uneven shrinkage and deformation caused by rapid cooling;

[0033] 9. In the present invention, the welding device for producing chemical container cylinder assemblies can realize automatic synchronous welding of the inner and outer rings of the cylinder body through the internal welding mechanism and the external welding mechanism, and can automatically adjust the power and cooling rate of the welding gun according to the moving line of the welding gun relative to the workpiece through the linkage mechanism and the adjustment mechanism, so as to ensure uniform and efficient welding.

The air inlet of the vacuum pump 12 is connected to an exhaust pipe, and the other end of the exhaust pipe is connected to the welding box 1.

[0066] In this embodiment, a placement opening is opened on one side of the welding box 1, and two sealing door panels 14 are slidably connected to one side of the welding box 1, a connecting seat 16 is fixedly installed on the top of the sealing door panel 14, an opening and closing motor 18 is fixedly installed on one side of the welding box 1, and a bidirectional screw 17 is fixedly installed on the output end of the opening and closing motor 18, and the two connecting seats 16 are threadedly connected to the outer side of the bidirectional screw 17;

[0067] A T-shaped guide rail is fixedly installed on one side of the welding box 1, a sealing door plate 14 is slidably sleeved on the outer side of the T-shaped guide rail 15, a fixing frame 401 is fixedly installed on the side wall of the welding box 1, a plurality of mounting rods are fixedly installed on one side of the welding frame 301, one end of the plurality of mounting rods is fixedly connected to the same annular electromagnetic heater 19, an induction coil is arranged inside the annular electromagnetic heater 19, and an electromagnetic controller of the annular electromagnetic heater 19;

[0068] A fixing ring 308 is fixedly installed on both sides of the welding frame 301 , and the arc seat 303 is slidably sleeved on the outer side of the fixing ring 308 .

[0069] When the present invention is in use, the opening and closing motor 18 is started to drive the bidirectional screw 17 to rotate, and the bidirectional screw 17 drives the two sealing door panels 14 away from each other through the thread transmission with the two connecting seats 16 and under the guidance of the T-shaped guide rail 15, so as to realize opening, and the cylinder components to be welded are sequentially placed in the two positioning mechanisms 2, and the rotating ring 203 is driven to rotate by starting the cylinder 209, and the rotating ring 203 drives the plurality of slide plates 207 to approach each other through the cooperation of the arc guide groove 204 and the connecting column 205, so that the clamping plate 208 abuts against the outside of the workpiece to realize clamping and fixing, and then the fifth electric push rod 202 is started to drive the two positioning mechanisms 2 to approach each other, so as to realize the splicing of the cylinder components;

[0070] By starting the opening and closing motor 18 to drive the two sealing plates to move closer to each other, the placement opening is sealed, and then the vacuum pump 12 is started to extract the air in the welding box 1 through the exhaust pipe, and the vacuum degree in the welding gun 506 box is monitored through the barometer 11. When the vacuum degree reaches the requirement, the vacuum pump 12 is controlled to stop and the control valve is started to introduce the inert gas into the welding box 1 through the inert gas introduction pipe 13;

[0071] By starting the annular electromagnetic heater 19, the electromagnetic controller converts the externally supplied alternating current into a high-frequency current. When the high-frequency current passes through the induction coil, an alternating magnetic field is generated, and countless small eddy currents are generated in the cylinder. These eddy currents make the cylinder itself heat up at a high speed, thereby achieving preheating of the cylinder, and the temperature of the cylinder is monitored by the infrared thermometer 505;

[0072] When the preheating temperature reaches 150°C to 200°C, the welding frame 301 and the upper welding gun 506 are driven to move left and right by starting the third electric push rod 302, and the moving frame 403 and the lower welding gun 506 are driven to move left and right by starting the fourth electric push rod 402, so that the two welding guns 506 are aligned with the splicing position, and then the first electric push rod 503 is started to drive the two mounting plates 504 to approach each other, so that the two abutting wheels 701 are respectively abutted against the inner and outer walls of the cylinder, and then the two welding guns 506 are started to achieve welding on both sides of the cylinder, and the driving motor 304 is started to drive the driving gear 305 to rotate, and the driving gear 305 drives the arc seat 303 to perform circular motion along the fixed ring 308 through engagement with the inner gear ring 306, and the rotating motor 404 is started to drive the mounting plate 408 to rotate, so that the two welding guns 506 can be driven to perform circumferential telescopic motion, so as to achieve automatic welding of different positions;

[0073] During the welding process, the two mounting plates 504 perform circular motion, so that they roll against the fitting cylinder, and drive the active bevel gear 703 to rotate synchronously through the rotating shaft 702. The active bevel gear 703 drives the vertical shaft 705 and the bending rod 801 to rotate through the meshing with the driven bevel gear 704. The bending rod 801 drives the connecting plate 802 and the counterweight block 803 to perform circular motion, so that the two connecting plates 802 move away from each other under the centrifugal force of the counterweight block 803. The two ends of the bending rod 801 are inclined, so that the two connecting plates 802 move vertically while moving away from each other, and through the action of the cross rail 805 and the disc 806 The lifting plate 807 is driven to move vertically, thereby compressing the compression spring 808 and squeezing the varistor 809. Since the varistor 809 is connected in series with the welding gun 506, the power of the welding gun 506 is correspondingly increased, and the greater the rotation speed of the abutting wheel 701, the greater the power of the welding gun 506, so that the power of the welding gun 506 is linearly related to the moving linear speed of the welding gun 506 relative to the workpiece. When the diameter of the cylinder to be welded increases and the rotation speed of the driving motor 304 and the rotating motor 404 increases, the moving linear speed of the welding gun 506 relative to the workpiece increases, so that the corresponding power of the welding gun 506 is greater, so as to ensure uniform and high-quality welding;

[0074] Before welding, the two conduits 509 need to be connected to the water supply pipe and the drainage pipe respectively. When the abutting wheel 701 rotates to drive the lifting vertical movement, the gate plate 9 moves synchronously, so that the through hole 901 on the gate plate 9 is connected with the cooling channel 507. Water directly flows into the cooling channel 507 through one of the conduits 509, passes through the annular cooling cavity 508, and is discharged from the other conduit 509. During this period, the welding gun 506 is cooled by water. When the rotation speed of the abutting wheel 701 increases and the power of the welding gun 506 increases, the downward movement distance of the gate plate 9 will increase, so that the conduction area between the through hole 901 and the cooling channel 507 increases, thereby increasing the water flow rate, so as to improve the cooling effect and prevent the welding gun 506 from overheating when running at high power.

[0075] The lower plate 605 and the upper plate 603 are driven to move up and down by starting the second electric push rod 608, so that the rotating wheel 601 abuts against the outside of the cylinder, and then the mounting plate 408 and the arc seat 303 rotate to drive the two flatness detection mechanisms 6 to perform circular motion. When the rotating wheel 601 contacts the weld, the weld pushes the upper plate 603 to approach the lower plate 605 through the abutment with the rotating wheel 601, and squeezes the connecting spring 602. The pressure of the connecting spring 602 is monitored by the pressure sensor 604, and the pressure limit value and the variation variance are calculated through the control panel 10, so as to determine whether the weld meets the requirements;

[0076] After welding is completed, the third electric push rod 302 is started to drive the welding frame 301 to move horizontally, so that the annular electromagnetic heater 19 is located at the periphery of the weld, and the annular electromagnetic heater 19 is started to achieve heat insulation treatment of the weld.
