Detailed Description
The technical scheme of the utility model is described in detail below with reference to the accompanying drawings:
example 1
A double-liquid reversing quenching device of a mesh belt furnace is used for being matched with the mesh belt furnace to finish quenching treatment of two workpieces with different materials.
As shown in fig. 2 and 3, the mesh belt furnace comprises a furnace body 6 and a conveyor belt 5 positioned in the furnace body 6. A heating device is arranged in the furnace body 6. The workpiece to be quenched is gradually heated to a designated temperature and a designated heat preservation time along with the travelling of the conveying belt 5 from the feeding end of the furnace body 6, finally falls into the quenching tank 7 from the discharging end, and is quenched after being cooled by the quenching medium.
The core of the device is that the reversing and distributing mechanism is shown in figure 1: the reversing and distributing mechanism comprises a feeding part 1 and two discharging parts 3. The feeding part 1 is bucket-shaped, and an inlet at the top is positioned below the discharging end of the conveying belt 5 and used for receiving falling high-temperature workpieces. Both discharge portions 3 are cylindrical and are arranged in a bifurcated manner with respect to the feed portion 1. The inlets at the upper ends of the two discharging parts 3 are connected with the outlets at the bottom of the feeding part 1. A rotating plate 2 is further arranged in the feeding part 1, and when the rotating plate 2 rotates to block the inlet of the discharging part 3 on one side, a workpiece falls into the other discharging part 3 which is open.
Correspondingly, as shown in fig. 2 and 3, the device is provided with two quenching areas, and two different quenching media are respectively placed in the two quenching areas. One embodiment is: the quenching tank 7 has two parts, which constitute a first quenching area and a second quenching area, respectively. Another embodiment is: the quenching tank 7 is a part in which a riser 9 is provided, the riser 9 dividing the quenching tank 7 into a first quenching zone and a second quenching zone. A second embodiment is shown in fig. 2 and 3.
Correspondingly, the outlets of the lower ends of the two outfeed portions 3 are located in the first quenching zone and in the second quenching zone, respectively.
The majority of the discharge portion 3 is immersed in the quenching medium, and the workpiece starts to contact with the quenching medium after entering the discharge portion 3.
As shown in fig. 1, further, the reversing and distributing mechanism further comprises a telescopic rod 4 for driving the rotating plate 2 to rotate. The telescopic rod 4 is an air cylinder or an electric telescopic cylinder. The rotating plate 2 is arranged on a rotating shaft, the rotating shaft is rotationally connected with the feeding part 1, and a connecting rod is further connected to the rotating shaft. One end of the telescopic rod 4 is rotationally connected with the shell of the feeding part 1 or the discharging part 3, and the other end of the telescopic rod is rotationally connected with the connecting rod. When the telescopic rod 4 stretches out and draws back, the rotating plate 2 is driven to rotate, and the purpose of distributing materials is achieved.
Further, as shown in fig. 4, the discharging portion 3 is provided with a plurality of baffles 10 arranged up and down and staggered, one end of each baffle 10 is connected with the inner wall of the discharging portion 3, and the other end is suspended. In this embodiment, the baffle 10 is disposed obliquely, and the oblique angle is 30 degrees to 60 degrees. The baffle 10 is higher at the end connected to the inner wall of the discharge portion 3 than at the other end.
Further, a lifter 8 is further arranged in each of the first quenching area and the second quenching area. The outlet at the lower end of the discharging part 3 is positioned above the corresponding feeding end of the lifting machine 8
In the embodiment, the quenching treatment is required to be carried out on the workpieces made of two different materials, namely the No. 45 steel medium carbon steel and the No. 40Cr medium carbon alloy steel, and the heating temperature and the heat preservation time of the quenching treatment and the quenching treatment are set through a control system of the mesh belt furnace, so that the workpieces are heated and preserved through the same mesh belt furnace successively, and the requirements of the workpieces on the heating temperature and the heat preservation time are met. On the other hand, the quenching medium required is different from that required for the first quenching medium, which is usually cooled in water (in the first quenching zone), and the second quenching medium, which is required to be cooled in a special quenching liquid (in the second quenching zone).
The quenching process is as follows: during feeding, workpieces of one material are placed continuously, then workpieces of the other material are placed according to the requirement, and the workpieces of No. 45 steel are placed firstly. The work piece travels with the conveyor belt 5 and is heated to a specified temperature and holding time (the heating temperature and the conveyor belt running speed are different when different work pieces enter the mesh belt furnace), and then falls from the blanking end. Firstly, a 45-steel workpiece reaches the blanking end, at the moment, the rotating plate 2 is rotated to one side to block the inlet of the discharging part 3 corresponding to the second quenching area, the workpiece enters the first quenching area along the current open discharging part 3, is cooled in water, and the workpiece falling onto the corresponding lifting machine 8 is conveyed out of the quenching tank 7 under the action of the lifting machine 8. According to the placing time interval of the workpieces of different materials and the running speed of the conveying belt, the time for the workpieces of 40Cr materials to reach the discharging end can be calculated, at the moment, the rotating plate 2 rotates to the other side to block the inlet of the discharging part 3 corresponding to the first quenching area, the workpieces enter the second quenching area along the current open discharging part 3, are cooled in special quenching liquid, and the workpieces falling onto the corresponding lifting machine 8 are conveyed out of the quenching tank 7 under the action of the lifting machine 8.
Further, when the workpiece falls down along the discharging portion 3, the workpiece is caused to move in a meandering manner by the baffle 10, so that the residence time of the workpiece in the cooling medium is prolonged and the workpiece is brought into sufficient contact with the cooling medium. Meanwhile, as the baffle 10 is obliquely arranged, after the workpiece moves to one end of the baffle 10 which is suspended, the workpiece can automatically turn over and fall onto the next layer of baffle 10 under the action of gravity, and the surface of the workpiece, which is originally downward and is contacted with the baffle 10, is turned upwards after being turned over and is fully contacted with the quenching medium, so that different side surfaces of the workpiece can be fully contacted with the quenching medium, and the tissue is more uniform after quenching.
