Description

Technical Field

[0001] This utility model relates to the field of induction heating equipment, and in particular to an automated impeller reflux device. Background Technology

[0002] Some large impellers have shafts welded on them. After welding, the impeller needs to be quenched and then tempered to reduce or eliminate internal stress in the quenched steel, or to reduce its hardness and strength, in order to improve its ductility or toughness. During the tempering process, an induction coil can be used to inductively heat the impeller. The induction end of the induction coil matches the diameter of the shaft, and the induction end is connected to the control cabinet through a connecting section. However, due to the large size of the impeller, the overall size of its induction coil is also relatively large. When the specifications of the impeller to be tempered change, the induction coil needs to be replaced to match the diameter of the shaft. However, the bulky induction coil brings many inconveniences to the replacement operation. First, its connecting section needs to be removed from the control cabinet, resulting in low removal efficiency. Moreover, the space for removing the induction coil after removal within the equipment is limited, further reducing the replacement efficiency. Therefore, it is necessary to develop an automated impeller tempering device to solve the above problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figs. 1 to 5As shown, an automated impeller tempering device includes a frame 1, a workbench 2, a control cabinet 3, a split-type coil 4, a lifting drive device 5, a pressure plate 6, and a placement platform 7. The workbench 2 and control cabinet 3 are both fixed to the frame 1. The split-type coil 4 includes a fixed connection assembly 41 and a splicing heating assembly 42. The fixed connection assembly 41 includes a first connecting plate 411 and a connecting rod 412. The first connecting plate 411 is fixed to the workbench 2, and the upper end of the connecting rod 412 is fixed to the first connecting plate 411. The lower end of the connecting rod 412 is electrically connected to the control cabinet 3. Two sets of the first connecting plate 411 and the connecting rod 412 are arranged side-by-side. The splicing heating assembly 42 includes a second connecting plate 421, a heating straight tube 422, an annular tube 423, and a fixing block 424. Two sets of the second connecting plate 421 are arranged, with their lower ends respectively... Two sets of heating straight tubes 422 are arranged in contact with the upper surfaces of the two sets of first connecting plates 411 and are respectively fixed to the front ends of the two sets of first connecting plates 411. The left and right ends of the opening of the annular tube 423 are respectively fixed to the front ends of the two sets of heating straight tubes 422. The left and right ends of the fixing block 424 are respectively fixed to the rear ends of the two sets of second connecting plates 421. The lifting drive device 5 is fixed on the worktable 2. The pressure plate 6 is fixed to the power output end of the lifting drive device 5 and its lower end surface is in contact with the upper end surface of the second connecting plate 421. The placement platform 7 is erected above the annular tube 423. The placement platform 7 is provided with a first placement hole 711 corresponding to the upper part of the annular tube 423. The worktable 2 is provided with a second placement hole 21 corresponding to the lower part of the annular tube 423. The worktable 2, the fixing block 424, the pressure plate 6 and the placement platform 7 are all made of insulating material.

[0021] The lifting drive device 5 drives the pressure plate 6 to press down on the second connecting plate 421, so that the second connecting plate 421 and the first connecting plate 411 are connected. When tempering the impeller, the shaft on the impeller is inserted into the first placement hole 711 and passes through the annular tube 423 and the second placement hole 21 in sequence. The lower end face of the impeller body is placed on the placement platform 7. The control cabinet 3 passes current into the split coil 4. The current passes through the connecting rod 412, the first connecting plate 411, the second connecting plate 421, the heating straight tube 422 in sequence and then flows through the annular tube 423. It then flows from another set of heating straight tubes 422 to another set of connecting rods 412, thus forming a circuit. An induced current is generated on the impeller and the temperature rises, thus realizing the tempering heating process. After the heating is completed, the impeller is cooled, thus completing the tempering. The advantage of this design is that the coil adopts a split design. When the coil needs to be replaced, the pressure plate 6 can be raised by the lifting drive device 5 to remove the splicing heating component 42. Only the splicing heating component 42 that matches the outer diameter of the impeller shaft needs to be replaced, without replacing the fixed connection component 41. Therefore, the process of disassembling the fixed connection component 41 from the control cabinet 3 can be eliminated. Moreover, the splicing heating component 42 is small in size, easy to disassemble and install, and also improves the efficiency of replacement.

[0022] The lifting drive device 5 includes an insulating bracket, a top plate, a screw, and a lifting plate. The insulating bracket is fixed on the workbench 2 and corresponds to the left and right sides of the pressure plate 6. The left and right sides of the top plate are respectively fixed to the upper ends of the two sets of insulating brackets. The screw is threaded to the top plate. The left and right sides of the lifting plate are slidably connected to the two sets of insulating brackets. The lower end of the screw is rotatably mounted on the lifting plate. The pressure plate 6 is fixed below the lifting plate.

[0023] The upper end of the screw is equipped with a hexagonal prism. The screw is driven to rotate by tools such as a wrench or handwheel, thereby driving the lifting plate to move up and down, and driving the pressure plate 6 to release or press the second connecting plate 421, so as to disassemble or install the splicing heating component 42.

[0024] The placement platform 7 includes a carrier plate 71, a left limiting plate 72, and a right limiting plate 73. The carrier plate 71 has a first placement hole 711 in the middle. The left limiting plate 72 and the right limiting plate 73 correspond to the left and right sides of the annular tube 423, respectively. The left limiting plate 72 has a first strip hole 721 and a first V-groove 722 that contacts the outer wall of the annular tube 423 on its right side. The left side of the carrier plate 71 and the left limiting plate 72 are fixed to the worktable 2 by screws passing through the first strip hole 721. The right limiting plate 73 has a second strip hole 731 and a second V-groove 732 that contacts the outer wall of the annular tube 423 on its right side. The right side of the carrier plate 71 and the right limiting plate 73 are fixed to the worktable 2 by screws passing through the second strip hole 731.

[0025] The carrier plate 71 supports the impeller body, while the left limiting plate 72 and the right limiting plate 73 are used to fix the annular tube 423. When replacing the splicing heating component 42, the screws on the carrier plate 71 are removed, and the carrier plate 71 is taken out to remove the splicing heating component 42. After the replacement evaluation heating component is placed in, the carrier plate 71 is reinstalled. With the screws not fully tightened, the left limiting plate 72 and the right limiting plate 73 can move left and right through the first strip hole 721 and the second strip hole 731 to accommodate and limit the annular tube 423 of different diameters. The first V-groove 722 and the second V-groove 732 clamp the annular tube 423.

[0026] In this design, a positioning block 8 is also included. The rear end of the positioning block 8 is provided with a positioning groove 81. The positioning block 8 is fixed on the workbench 2 by screws and corresponds to the front side of the annular tube 423. The splicing heating assembly 42 also includes a positioning rod 425. The rear end of the positioning rod 425 is fixed to the front end of the annular tube 423, and the front end of the positioning rod 425 is inserted into the positioning groove 81. The upper end face of the positioning rod 425 is in contact with the positioning groove 81.

[0027] When installing the splicing heating assembly 42, first insert the front end of the positioning rod 425 into the positioning groove 81. After it is inserted into place, tighten the screws on the positioning block 8 so that the positioning block 8 presses down on the front end of the positioning rod 425. At this time, the second connecting plate 421 is accurately positioned above the first connecting plate 411, thereby improving the positional accuracy of the connection.

[0028] This design also includes a barcode scanning component 9, which includes a protective housing 91, a telescopic drive component 92, a barcode scanner 93, and a protective cover 94. The protective housing 91 is fixed on the frame 1, the telescopic drive component 92 is fixed inside the upper side of the protective housing 91, and an opening is provided at the lower end of the protective housing 91 near the annular tube 423. The barcode scanner 93 is fixed to the power output end of the telescopic drive component 92 and corresponds to the lower side inside the protective housing 91. The protective cover 94 is fixed to one side of the barcode scanner 93 and corresponds to the opening.

[0029] Before heating the impeller, the barcode scanner 93 can be extended by the telescopic drive component 92 to scan and record the QR code on the impeller for subsequent traceability of production data. Then, the telescopic drive component 92 drives the barcode scanner 93 to retract into the protective housing 91 and covers the opening of the protective housing 91 with the protective cover 94, thereby preventing the barcode scanner 93 from being damaged by high temperature during the heating process.

[0030] This design also includes a guide sleeve 10. The upper end of the guide sleeve 10 is fixed on the workbench 2 and corresponds to the second placement hole 21. A limiting circular hole 101 is vertically provided on the guide sleeve 10, and a chamfer is provided on the outer periphery of the upper end of the limiting circular hole 101.

[0031] When placing the impeller, the lower end of the impeller shaft enters the limiting circular hole 101 of the guide sleeve 10 through a chamfer, thereby making the impeller placement more accurate and thus making the heating of the impeller by the annular tube 423 more uniform.

[0032] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
