Description

Technical Field

[0001] The utility model relates to the technical field of flange welding, in particular to a flange welding machine. Background Art

[0002] After the flange rough is produced, the flange fracture needs to be connected to form a complete ring. The flange fracture is welded by a welding machine.

[0003] When the existing welding machine welds the flange, the two left and right welding mechanisms will press the two ends of the flange's seam, and the welding mechanism will press the flange up and down through two electrode conductors. During the downward pressing process, the oil cylinder will drive the electrode conductor at the bottom of the connecting plate to move downward, and cooperate with another electrode conductor below to press the flange. The electrode conductor as a whole is generally made of beryllium-chromium copper alloy. This alloy copper has the advantages of high hardness and good conductivity. It plays a conductive role during welding. However, after long-term use, the surface of the two electrode conductors is easily deformed during the repeated pressing of the flange, which affects the use. When replacing, the entire electrode conductor needs to be replaced together, which is costly. At the same time, a cylinder is formed in an upward protrusion on the upper part of the connecting plate. The cylinder will be connected to the oil cylinder, and the oil cylinder drives the cylinder to drive the connecting plate to move downward as a whole. Since the cylinder is cast together with the connecting plate, it is easy to break due to the large force after long-term use. When replaced, it can only be replaced together with the connecting plate. This undoubtedly further increases the maintenance and replacement cost of the welding machine. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a preferred embodiment of the utility model proposes a flange welding machine, which is mainly composed of two welding mechanisms 1, which are arranged symmetrically with a certain gap between them. The flange is divided into two halves with the fracture as the boundary, and each half of the flange is pressed up and down by a welding mechanism 1, and then the flange is energized to generate high temperature, and the fracture of the flange is squeezed so that the fracture of the flange is welded together.

[0026] like Figure 2 As shown, the structures of the two welding mechanisms 1 are the same. Each welding mechanism 1 is composed of a body 11, a conductor connecting plate 13, a conductor fixing seat 14, an electrode conductor 15, a driving mechanism 12 and other components, wherein the side of the body 11 has a "concave" opening, and the driving mechanism 12 is installed on the top of the body 11.

[0027] refer to Figure 3 , Figure 4In this embodiment, the acquisition mechanism is composed of a clamping cylinder 121, a clamping shaft 122 and a sleeve 123. The clamping cylinder 121 is fixed on the top of the machine body 11, and the clamping shaft 122 is located inside the sleeve 123 and can slide up and down along the sleeve 123. The sleeve 123 plays a guiding role. In other technical solutions, electric cylinders, air cylinders, etc. can also be used as driving components.

[0028] refer to Figure 5 , Figure 6 A connecting column 19 is provided at one end of the upper part of the conductor connecting plate 13. The connecting column 19 is detachably connected to the conductor connecting plate 13. When the connecting column 19 is broken, the connecting column 19 can be replaced at any time. The upper end of the above-mentioned clamping shaft 122 is connected to the output end of the clamping oil cylinder 121, and the lower end is provided with a connecting hole 1221 for connecting with the connecting column 19. The conductor connecting plate 13 is located on the upper side of the side opening of the machine body 11, and the clamping oil cylinder 121 drives the conductor connecting plate 13 to move up and down through the clamping shaft 122.

[0029] A circular connecting groove 131 is provided on the upper part of the conductor connecting plate 13, and a socket 132 connected to the connecting groove 131 is provided on the side of the conductor connecting plate 13. A plug 20 is provided in the socket 132, and a through socket 132 is also provided on the side of the connecting column 19. When the lower end of the connecting column 19 is inserted into the connecting groove 131, the plug 20 is inserted from the socket 132 on the side of the conductor connecting plate 13, and the plug 20 completely passes through the socket 132 on the connecting column 19, thereby fixing the connecting column 19 on the conductor connecting plate 13.

[0030] In other technical solutions, a semicircular slot 191 can also be opened on the side of the connecting column 19. The slot 191 passes through from front to back, and the socket 132 on the conductor connecting plate 13 is partially offset from the connecting groove 131. In this way, when the pin 20 is inserted into the slot 191, half of the pin 20 will be embedded in the slot 191, and the other half will be engaged with the conductor connecting plate 13, thereby fixing the connecting column 19 on the conductor connecting plate 13.

[0031] After the connection column 19 is fixed, the plug 20 is fixed to the conductor connection column 19 by screws. If the connection column 19 is broken, only the plug 20 needs to be pulled out, and then the connection column 19 can be disassembled.

[0032] like Figure 2As shown, a conductor fixing seat 14 is provided at the bottom of the conductor connecting plate 13, and a conductor fixing seat 14 is also provided below the conductor fixing seat 14, and the two conductor fixing seats 14 are arranged in parallel up and down. Two electrode conductors 15 are also provided, which are respectively installed and fixed at the same position on the opposite sides of the two conductor fixing seats 14, and the electrode conductors 15 are located directly below the connecting column 19, so that the electrode conductors 15 are subjected to greater and more uniform force when pressed down.

[0033] refer to Figure 7 The electrode conductor 15 is composed of a base 151 and an electrode plate 152. The electrode plate 152 is made of beryllium-chromium copper alloy material and plays a conductive role. A card block 1511 is formed in the middle position of the upper part of the base 151, and the card block 1511 extends from one end of the base 151 to the other end. At the same time, a card slot matching the card block 1511 is provided at the bottom of the electrode plate 152. The card block 1511 is connected to the card slot. Several screw holes are also provided on the electrode plate 152. After the electrode plate 152 is connected to the base 151, it is fixed to the base 151 by screws. The base 151 is made of conventional materials and may not be conductive. When the electrode plate 152 is deformed due to long-term pressing, the electrode plate 152 can be removed from the base 151 for replacement, thereby reducing the replacement cost.

[0034] In order to fix the base 151, stepped clamping parts are formed on both sides of the base 151, and a pressure plate 18 is provided at the location of each clamping part. The shape of the pressure plate 18 is also stepped, and it cooperates with the clamping part to clamp and fix the two sides of the base 151 on the conductor fixing seat 14. The pressure plate 18 is fixed to the clamping fixing seat by bolts.

[0035] refer to Figure 2 A guide seat 16 is provided on the side of the body 11, and a guide hole penetrating from top to bottom is opened on the guide seat 16. A guide rail 17 is provided at the end of the conductor connecting plate 13 away from the electrode conductor 15. The guide rail 17 is slidably connected to the guide hole. When the conductor fixing seat 14 located on the upper layer moves up and down with the conductor connecting plate 13, the guide seat 16 can play a guiding role to ensure that the position of the conductor fixing seat 14 located on the upper layer will not be deviated when it moves up and down.

[0036] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
