Description

Technical Field

[0001] The utility model relates to the technical field of forging heating, in particular to an automatic feeding device of a forging heating furnace. Background Art

[0002] A forging heating furnace is a device used to heat metal workpieces, mainly heating the workpieces to forging temperature. Forging heating furnaces can be divided into flame heating furnaces and electric heating furnaces. Flame heating furnaces can be further divided into oil furnaces, gas furnaces and coal-fired furnaces according to different fuels, while electric heating furnaces include medium-frequency induction heating furnaces, etc. The furnace structure will change accordingly according to the type of workpiece that needs to be heated. For example, for longer rod-like workpieces, since the body of such workpieces is longer, they are generally heated using a two-way open furnace body. By passing the rod-like workpiece through the furnace body, the rod-like workpiece is heated in sequence, so that the workpiece as a whole is heated to a suitable temperature. When heating the workpiece, it is necessary to manually insert the workpiece into the heating furnace and move it, which is more dangerous. In addition, some heating furnaces, such as medium-frequency induction heating furnaces, require the workpiece to be moved to the center of the furnace body in order to more evenly heat the workpiece part located inside the furnace body. Generally, rod-like workpieces are longer and heavier, and it is more difficult to manually feed the workpiece and keep the workpiece always located in the center of the furnace body, which is more inconvenient.

[0028] The furnace body 100 is a structure with openings at both ends;

[0029] Two pulling mechanisms 200 are respectively located at the openings at both ends of the furnace body 100. The pulling mechanism 200 includes a frame body 210, and both ends of the top and bottom of one side of the frame body 210 are fixedly connected with U-shaped plates 220. The other side of the frame body 210 is fixedly connected with two connecting plates 211, and one end of the two connecting plates 211 is respectively fixedly connected to the top and bottom surfaces of the furnace body 100. The two arms of the two U-shaped plates 220 are provided with card slots 221 on the opposite sides. A plurality of movable frames 230 arranged transversely in sequence are provided between the two U-shaped plates 220. Two card blocks 231 are fixedly connected to the opposite sides of the plurality of movable frames 230. The four card blocks 231 on the same movable frame 230 are respectively slidably connected to the inside of the four card slots 221.

[0030] The two driving mechanisms 400 are respectively located at the two pulling mechanisms 200 .

[0031] Specifically, the multiple U-shaped plates 220 on the two pulling mechanisms 200 are initially in a state of being in contact with each other, and the rod-like workpieces are sequentially conveyed to the vicinity of the furnace body 100 by means of a conveyor belt, or a single rod-like workpiece is lifted to the vicinity of the furnace body 100 by means of a lifting device, and then the multiple U-shaped plates 220 on one pulling mechanism 200 are moved to separate the multiple U-shaped plates 220, and the rod-like workpieces are placed inside the multiple moving frames 230 and supported, and then the rod-like workpieces are moved to the moving frames 230.

When the multiple moving frames 230 on the pulling mechanism 200 are moved apart, the push rods 240 on the moving frame 230 farthest from the furnace body 100 can be slid to move the two push rods 240 on the moving frame 230 toward each other to clamp the rod-like workpiece, while the push rods 240 on the other moving frames 230 move up to hold the rod-like workpiece. When the plurality of movable frames 230 move and abut against each other, the movable frame 230 farthest from the furnace body 100 can use the two supporting rods 240 to clamp the workpiece and drive it through the furnace body 100, while the supporting rods 240 on the other movable frames 230 can support the workpiece to prevent the workpiece from tilting. The middle part of the supporting rod 240 is V-shaped so that the rod-like workpiece can naturally fall into the V-shaped part of the supporting rod 240 for positioning. The V-shaped parts of the two supporting rods 240 on the movable frame 230 farthest from the furnace body 100 are in opposite directions.

A driving motor is arranged inside the two motor boxes 310, and the motor shafts of the two driving motors pass through the adjacent U-shaped plates 220, and the motor shafts of the two driving motors are fixedly connected to the top ends of the two adjusting screw rods 320 respectively.

[0036] In a specific implementation, the adjusting screw rod 320 is a positive and negative threaded screw rod, so that when the driving motor is started to drive the adjacent adjusting screw rod 320 to rotate, the two moving plates 300 on the adjusting screw rod 320 can be driven to move toward or away from each other. The two abutting rods 240 on the moving frame 230 farthest from the furnace body 100 in a single pulling mechanism 200 are initially located at the top and bottom of the moving frame 230, respectively, and the abutting rods 240 on other moving frames 230 are all located at the bottom of the adjacent moving frames 230. The four moving plates 300 on a single pulling mechanism 200 are respectively two close to the lower U-shaped plate 220 and the other two close to the upper U-shaped plate 220. On a single pulling mechanism 200, the moving frame 230 farthest from the furnace body 100 The two plug plates 242 on the top support rod 240 are respectively inserted into the two brackets 301 located on the upper moving plate 300, while the two plug plates 242 on any other support rods 240 are respectively inserted into the two brackets 301 located on the lower moving plate 300. When the two driving motors are started, the two moving plates 300 on the adjacent adjusting screw rods 320 can be driven to move toward each other, so that the two support rods 240 on the moving frame 230 farthest from the furnace body 100 move toward each other to clamp the workpiece, and the support rods 240 on the other moving frames 230 are driven by the adjacent moving plates 300 to move and are in a parallel state with the support rod 240 located at the bottom on the farthest moving frame 230, thereby holding the rod-like workpiece, which is convenient for users to use.
