DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-3 A sintering furnace for cemented carbide rolling shears, comprising a sintering furnace body 1, a feed hopper 2 is installed on the top of the sintering furnace body 1, a discharge pipe 3 is installed on the bottom of the sintering furnace body 1, and a heat preservation layer 10, a heat insulation layer 11 and a heating element 12 are arranged on the sintering furnace body 1. The specific structure of the heating element 12 is not limited. Preferably, the heating element 12 is set as a silicon carbon rod, and further comprises:

[0021] A stirring component, which is arranged in the sintering furnace body 1 and is used to stir the cemented carbide placed therein;

[0022] A material shifting assembly, which is arranged in the sintering furnace body 1 and is used to shift the cemented carbide at the bottom of the sintering furnace;

[0023] The reciprocating assembly is arranged outside the sintering furnace body 1 and is used to drive the material shifting assembly.

[0024] The cemented carbide is put into the sintering furnace body 1 through the feed hopper 2, and then the put-in cemented carbide is heated and sintered by the heating element 12. In the process of sintering, the cemented carbide is stirred by the stirring component to prevent the cemented carbide from piling up and affecting its heating and sintering efficiency. The reciprocating component drives the material shifting component to reciprocate the cemented carbide at the bottom of the sintering furnace body 1, so that the cemented carbide at the bottom can be evenly distributed, avoiding the accumulation of cemented carbide, and the heating element 12 can evenly heat and sinter the cemented carbide, thereby further improving the sintering efficiency of the cemented carbide.

[0025] In one case of the present embodiment, the stirring assembly includes a rotating column rotatably arranged in the sintering furnace body 1, the cross-section of the rotating shaft 4 is non-circular, and a sleeve 6 is slidably arranged on the rotating shaft 4. Since the cross-section of the rotating shaft 4 is non-circular, when the rotating shaft 4 rotates, the sleeve 6 will also rotate synchronously. The outer wall of the sleeve 6 is installed with multiple groups of stirring rods 7 distributed at intervals, and the outer wall of the sintering furnace body 1 is installed with a motor 5 connected to the rotating shaft 4.

[0026] The motor 5 is started by an external controller, and the motor 5 drives the shaft 4 to rotate, and the shaft 4 drives the sleeve 6 to rotate, so that the stirring rod 7 rotates in the sintering furnace body 1, and then the cemented carbide in the sintering furnace body 1 can be stirred to prevent the cemented carbide from piling up and affecting the efficiency of heating and sintering.

[0027] In one case of this embodiment, the material shifting assembly includes a plurality of groups of spaced-apart brackets 198 mounted on the sleeve 6 , each group of brackets 198 is arranged between adjacent stirring rods 7 , and a shifting plate 9 is installed at one end of the bracket 198 away from the sleeve 6 .

[0028] During the rotation of the rotating shaft 4, the reciprocating component will be driven, so that the reciprocating component drives the sleeve 6 to move back and forth on the rotating shaft 4, so that the toggle plate 9 on the bracket 198 can move back and forth left and right, and then the cemented carbide flipped to the bottom of the sintering furnace body 1 can be toggled left and right, so that the cemented carbide is evenly spread, thereby facilitating uniform heating and sintering thereof, avoiding the accumulation of cemented carbide, and allowing the heating element 12 to evenly heat and sinter the cemented carbide, further improving the sintering efficiency of the cemented carbide.

[0029] In one case of this embodiment, the reciprocating assembly includes an oblique rotating column 18 installed at the end of the rotating shaft 4, and the oblique rotating column 18 is located outside the sintering furnace body 1, and a plurality of limiting cylinders 15 are installed at the end of the sintering furnace body 1, and a sliding rod 16 is slidably arranged in the limiting cylinder 15, and a movable plate 17 is installed at the end of the sliding rod 16 away from the sintering furnace body 1, and a bracket 198 is installed at the end of the movable plate 17 close to the oblique rotating column 18, and a roller 20 is movably installed on the bracket 198, and a spring 21 is arranged between the movable plate 17 and the sintering furnace body 1, and a connecting piece is arranged between the sliding rod 16 and the sleeve 6. The connecting piece includes a limiting frame 14 installed at one end of the sliding rod 16 located in the sintering furnace body 1, and the limiting frame 14 is rotatably connected to the turntable 13, and the turntable 13 is fixedly connected to the sleeve 6.

[0030] When the rotating shaft 4 rotates, it will drive the inclined rotating column 18 to rotate. Since the end of the inclined rotating column 18 is an inclined surface, the movable plate 17 will be pushed to move through the roller 20 and the bracket 198 during rotation. The reciprocating movement of the movable plate 17 can be achieved in conjunction with the spring 21, thereby achieving the left and right movement of the sleeve 6 through the limit frame 14 and the turntable 13.

[0031] The present invention puts the cemented carbide into the sintering furnace body 1 through the feed hopper 2, and then heats and sinters the put-in cemented carbide through the heating element 12. In the sintering process, the cemented carbide is stirred by the stirring component to prevent the cemented carbide from piling up and affecting the efficiency of heating and sintering. The reciprocating component drives the material shifting component to reciprocate the cemented carbide located at the bottom of the sintering furnace body 1, so that the cemented carbide at the bottom can be evenly distributed, avoiding the accumulation of cemented carbide, and the heating element 12 can evenly heat and sinter the cemented carbide, thereby further improving the sintering efficiency of the cemented carbide.
