[0026] The embodiment of the present application provides a hot electrode combination hexagonal pressing device.

[0027] like Figure 1 As shown, the thermode assembly includes a thermode 2 and a sleeve 1.

[0028] like Figure 1 and Figure 2 As shown, a thermoelectrode combined hexagonal pressing device comprises a positioning die 3, a hexagonal pressing die 4 and a driving mechanism 5. The hexagonal pressing die 4 is located on the first side surface 34 of the positioning die 3. The first side surface 34 of the positioning die 3 is provided with a positioning hole 31 extending to the inside of the positioning die 3. The positioning hole 31 is used to place the sleeve 1 and the thermoelectrode 2. The inner wall of the positioning hole 31 is provided with an annular flange 32 inclined relative to the circumferential section of the positioning hole 31. The annular flange 32 is used to contact the inclined end surface 12 of the sleeve 1. The inner ring of the annular flange 32 is used for the thermoelectrode 2 to pass through. In this embodiment, the first side surface 34 is the top surface of the positioning die 3, and the positioning hole 31 is arranged in the vertical direction. The positioning die 3 and the driving mechanism 5 are mounted on a base 6.

[0029] The driving mechanism 5 is used to drive the hexagonal pressing die 4 to apply circumferential pressure to the first preset position 11 of the sleeve 1, so that the first preset position 11 of the sleeve 1 is pressed against the second preset position 21 of the hot electrode 2, and the first preset position 11 of the sleeve 1 is deformed into a hexagon; when the inclined end face 12 of the sleeve 1 fits the annular flange 32, the first preset position 11 of the sleeve 1 is aligned with the hexagonal pressing die 4.

[0030] After the sleeve 1 is placed in the positioning hole 31, due to the action of gravity, the inclined end face 12 of the sleeve 1 fits with the top face of the annular flange 32, realizing the automatic positioning of the sleeve 1 in the axial and radial directions. At this time, the first preset position 11 of the sleeve 1 is exposed from the positioning hole 31 and corresponds to the hexagonal pressing mold 4; the thermode 2 is passed through the sleeve 1, and the second preset position 21 of the thermode 2 is aligned with the first preset position 11 of the sleeve 1. Then, the driving mechanism 5 is started to make the hexagonal pressing mold 4 apply circumferential pressure to the first preset position 11 of the sleeve 1, so that the first preset position 11 of the sleeve 1 is pressed tightly on the second preset position 21 of the thermode 2, and the first preset position 11 of the sleeve 1 is deformed into a hexagon, realizing the hexagonal pressing operation of the thermode group.

[0031] The positioning hole 31 is also provided with a stopper 33 for abutting against the end face of the thermode 2. The stopper 33 is located on the side of the annular flange 32 away from the first side face 34. When the end face of the thermode 2 abuts against the stopper 33, the second preset position 21 of the thermode 2 is aligned with the hexagonal pressing mold 4. After the thermode 2 is placed in the sleeve 1, the end face of the thermode 2 abuts against the stopper 33 under the action of its own gravity. At this time, the second preset position 21 of the thermode 2 is aligned with the hexagonal pressing mold 4.

[0032] The present application can quickly put the sleeve 1 and the hot electrode 2 in place by disposing the annular flange 32 and the limiting platform 33, thereby improving the efficiency of the hexagonal pressing operation.

[0033] like Figure 3As shown, the positioning mold 3 is provided with a plurality of inclined slots 321 inclined relative to the circumferential cross-section of the positioning hole 31, and the plurality of inclined slots 321 are sequentially distributed along the length direction of the positioning hole 31, and the inclined slots 321 are connected to the positioning hole 31, and a plug plate is inserted in any of the inclined slots 321, and the plug plate is provided with a through hole for the heating electrode 2 to pass through, and after the plug plate and the inclined slot 321 are matched, the through hole is located in the positioning hole 31, and the plug plate at the edge of the through hole protrudes from the inner wall of the positioning hole 31 and forms the annular flange 32. By inserting the plug plate in different inclined slots 321, the annular flange 32 can adapt to the sleeves 1 with different hexagonal pressing positions, thereby improving the applicable scope of the hexagonal pressing equipment. Among them, the inclined slot 321 passes through the side wall of one side of the positioning mold 3, and the plug plate is inserted into the inclined slot 321 from the opening of the positioning mold 3 corresponding to the inclined slot 321, until the plug plate abuts against the bottom of the inclined slot 321, and the plug plate and the inclined slot 321 form a match.

[0034] The positioning mold 3 is provided with a plurality of positioning slots 331 parallel to the circumferential cross section of the positioning hole 31. The positioning slots 331 penetrate the side wall of one side of the positioning mold 3. The plurality of positioning slots 331 are sequentially arranged along the length direction of the positioning hole 31. The positioning slots 331 are connected to the positioning hole 31. A positioning plate is inserted into any of the positioning slots 331 to form the limiting platform 33. By inserting positioning plates into different positioning slots 331, the limiting platform 33 can adapt to the hot electrodes 2 with different hexagonal pressing positions, thereby improving the applicable scope of the hexagonal pressing equipment. Among them, the positioning slot 331 penetrates the side wall of one side of the positioning mold 3, and the positioning plate is inserted into the positioning slot 331 from the opening of the positioning slot 331 of the positioning mold 3 until the insert plate abuts against the bottom of the positioning slot 331, and the positioning plate and the positioning slot 331 form a match.

[0035] like Figure 2 As shown, the hexagonal pressing die 4 includes molding plates arranged on both sides of the positioning hole and a movable rod 41 connecting the molding plates. The two molding plates are butted to form a hexagonal sleeve. The movable rod 41 is slidably installed on the first side surface 34. One end of the movable rod 41 is connected to the molding plate. The driving mechanism 5 applies pressure to the other end of the movable rod 41, so that the two movable rods 41 drive the two molding plates to approach each other. A guide sleeve 43 is provided on the first side surface 34. The movable rod 41 passes through the guide sleeve 43. The end of the movable rod 41 away from the molding plate is provided with a protrusion 42 protruding along the radial direction of the movable rod 41. A spring 44 is provided between the guide sleeve 43 and the protrusion 42 and is sleeved on the outer periphery of the movable rod 41. When the two movable rods 41 are close to each other and the two molding plates are butted, the two ends of the spring 44 are respectively pressed on the guide sleeve 43 and the protrusion 42, and the spring 44 is in a compressed state.

[0036] After the driving mechanism 5 applies pressure to the movable rod 41, the movable rod 41 slides along the guide sleeve 43, and the movable rod 41 drives the molding plates to dock and compact the sleeve 1. After the force of the driving mechanism 5 is removed, the movable rods 41 move away from each other under the elastic force of the spring 44, so that the molding plates move away from each other, and the separation of the molding plates is automatically completed.

[0037] The driving mechanism 5 includes electric cylinders 51 disposed on opposite sides of the positioning mold 3 , one end of the movable rod 41 away from the shaping plate extends out of the positioning mold 3 , and the output end of the electric cylinder 51 is aligned with the movable rod 41 .

[0038] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
