Technical Field

[0001] The utility model relates to the technical field of die steel production, in particular to a rapid quenching processing device for die steel. Background Technique

[0002] Quenching processing is an important production stage of die steel. In the quenching cooling stage, the selection of the cooling medium is very important. Oil cooling, air cooling, water cooling or polymer cooling each has its own advantages and disadvantages. For example, oil cooling has a moderate cooling speed and is suitable for most die steels, but it is flammable and safety needs to be noted. Water cooling has a fast speed and is easy to cause deformation or cracking, so the time needs to be strictly controlled.

[0003] The existing oil quenching equipment can stably cool die steel, but due to the viscosity of the oil, not only the self-flow effect of the oil during cooling is poor due to the temperature difference at each part, resulting in low cooling efficiency, but also a large amount of oil remains on the die steel and cannot be quickly cleaned. Therefore, a rapid quenching processing device for die steel needs to be designed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rapid quenching processing device for die steel to solve the problems in the above background technique that the self-flow effect of the oil in the existing equipment is poor due to the temperature difference at each part, resulting in low cooling efficiency, and a large amount of oil remains on the die steel and cannot be quickly cleaned.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid quenching processing device for die steel, including a quenching tank, a support plate is fixed at the rear side of the quenching tank, a reinforcing plate is installed on the top of the support plate, a vertical hydraulic rod is fixed on the horizontal part of the support plate, a substrate is installed at the bottom end of the vertical hydraulic rod, a horizontal hydraulic rod is fixed on one side of the top surface of the substrate, the end of the horizontal hydraulic rod is connected and fixed to one side of a movable plate, a drag-reducing pulley is rotatably installed at the bottom edge of the vertical part of the movable plate, the bottom end of the drag-reducing pulley is in contact with the top surface of the substrate, the vertical part of the movable plate passes through a track window, the track window is opened on the substrate, a stabilizing rod is fixed in the middle of the inner wall of the track window, the stabilizing rod passes through a stabilizing hole, the stabilizing hole is opened on the vertical part of the movable plate, a connecting rod is installed at the bottom end of the vertical part of the movable plate, a placing basket is fixed at the bottom end of the connecting rod, a partition mesh plate is installed inside the placing basket, a servo motor is fixed on one side of the quenching tank, and a flow-promoting fan blade is fixed at the end of the output shaft of the servo motor.

[0006] Preferably, the side view shape of the movable plate is "inverted U", and the vertical part of the movable plate is in sliding connection with the track window.

[0007] Preferably, the drag-reducing pulleys are symmetrically distributed about the center of the movable plate, and the drag-reducing pulleys are densely installed at equal intervals on the bottom edge of the horizontal part of the movable plate.

[0008] Preferably, the stabilizing hole and the stabilizing rod are slidably connected, and the center of the stabilizing hole and the center of the vertical part of the movable plate are on the same vertical plane.

[0009] Preferably, both the placement basket and the separator mesh are provided with fine mesh holes, and the diameter of the mesh holes on the placement basket is not greater than the diameter of the mesh holes on the separator mesh.

[0010] Preferably, a waste discharge pipe is installed at one end of the bottom of the quenching box, and the inner bottom surface of the quenching box is set as an inclined surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the mold steel rapid quenching processing device adopts a new structural design, which can not only drive the container structure to move horizontally when the mold steel is immersed in cooling to promote the flow of oil, but also further promote the flow of oil and improve the cooling efficiency through the oil driving mechanism. At the same time, it can shake the container structure after cooling to accelerate the separation speed of the oil adhering to the surface of the mold steel.

[0012] 1. Driven by a horizontal hydraulic rod, the movable plate moves horizontally back and forth steadily along the track window under the support of the drag-reducing pulley. This not only allows the placement basket and mold steel to move horizontally back and forth in the oil, promoting contact between the coolant and the mold steel, but also allows the oil adhering to the surface of the mold steel to be quickly shaken off after quenching.

[0013] 2. The servo motor and flow-promoting fan blades can further promote the flow of oil in the quenching chamber. Combined with the structural design of the placement basket and partition plate, the flow rate of oil in the quenching chamber is accelerated, thereby improving the overall cooling efficiency, avoiding local oil overheating and combustion, and reducing the possibility of production accidents.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-4 , the present utility model provides a technical solution: a rapid quenching processing device for die steel, including a quenching tank 1, a support plate 2, a reinforcing plate 3, a vertical hydraulic rod 4, a base plate 5, a horizontal hydraulic rod 6, a movable plate 7, a drag reduction pulley 8, a track window 9, a stabilizing rod 10, a stabilizing hole 11, a connecting rod 12, a placement basket 13, a partition mesh plate 14, a servo motor 15, a flow promoting fan blade 16 and a waste discharge pipe 17. A support plate 2 is fixed at the rear side of the quenching tank 1, a reinforcing plate 3 is installed on the top of the support plate 2, a vertical hydraulic rod 4 is fixed on the horizontal part of the support plate 2, a base plate 5 is installed at the bottom end of the vertical hydraulic rod 4, a horizontal hydraulic rod 6 is fixed on one side of the top surface of the base plate 5, the end of the horizontal hydraulic rod 6 is connected and fixed to one side of the movable plate 7, a drag reduction pulley 8 is rotatably installed at the bottom edge of the vertical part of the movable plate 7, the bottom end of the drag reduction pulley 8 is in contact with the top surface of the base plate 5, the vertical part of the movable plate 7 penetrates through the track window 9, the track window 9 is opened on the base plate 5, a stabilizing rod 10 is fixed in the middle of the inner wall of the track window 9, the stabilizing rod 10 penetrates through the stabilizing hole 11, the stabilizing hole 11 is opened on the vertical part of the movable plate 7, a connecting rod 12 is installed at the bottom end of the vertical part of the movable plate 7, a placement basket 13 is fixed at the bottom end of the connecting rod 12, a partition mesh plate 14 is installed inside the placement basket 13, a servo motor 15 is fixed on one side of the quenching tank 1, and a flow promoting fan blade 16 is fixed at the end of the output shaft of the servo motor 15.

[0021] In this example, the side view shape of the movable plate 7 is "inverted V", and the vertical part of the movable plate 7 is slidably connected to the track window 9. The above structural design makes the movable plate 7 more stable and can slide linearly and stably along the track window 9.

[0022] The drag reduction pulleys 8 are symmetrically distributed about the center of the movable plate 7, and the drag reduction pulleys 8 are densely installed at equal intervals at the bottom edge of the horizontal part of the movable plate 7. The above structural design can stably support the movable plate 7 and its bottom installation structure, and reduce the resistance of the movable plate 7 during horizontal movement, ensuring smooth horizontal reciprocating movement of the movable plate 7 and its bottom installation structure.

[0023] The stabilizing hole 11 and the stabilizing rod 10 are slidably connected, and the center of the stabilizing hole 11 and the center of the vertical part of the movable plate 7 are on the same vertical plane. The above structural design can further improve the stability of the movable plate 7 during horizontal movement and avoid the晃动 of the movable plate 7.

[0024] Both the placement basket 13 and the partition mesh plate 14 are provided with fine mesh holes. The diameter of the mesh holes on the placement basket 13 is not larger than the diameter of the mesh holes on the partition mesh plate 14. The above structural design ensures that the cooling oil can pass smoothly through the placement basket 13 and the partition mesh plate 14, ensuring the fluidity of the oil.

[0025] A waste discharge pipe 17 is installed at one end of the bottom of the quenching box 1, and the bottom surface of the inner side of the quenching box 1 is set as an inclined surface. The above structural design facilitates the discharge of waste oil and residue and facilitates the cleaning of the quenching box 1.

[0026] Working principle: When in use, inject an appropriate amount of cooling oil into the quenching box 1, place the mold steel to be quenched into the placement basket 13, control the symmetrically distributed vertical hydraulic rods 4 to extend synchronously, drive the base plate 5, movable plate 7 and placement basket 13 to move down until the placement basket 13 is completely submerged in the oil, control the vertical hydraulic rods 4 to lock, start the servo motor 15, the servo motor 15 drives the flow fan blades 16 to rotate stably, agitating the flow of coolant;

[0027] At the same time, the horizontal hydraulic rod 6 is activated, controlling it to first extend and then shorten. The horizontal hydraulic rod 6 drives the movable plate 7 to move horizontally and linearly back and forth along the track window 9. The mold steel in the basket 13 at the bottom of the movable plate 7 also moves synchronously. The oil enters the basket 13 stably to cool the mold steel and flows out smoothly. The oil in the quenching box 1 flows fully to avoid local overheating.

[0028] After cooling is complete, the vertical hydraulic rod 4 is shortened, causing the base plate 5, movable plate 7, and placement basket 13 to move upward and completely separate from the oil. At the same time, the horizontal hydraulic rod 6 continues to extend and retract horizontally, causing the placement basket 13 to shake horizontally, quickly shaking off the oil remaining on the placement basket 13 and the mold steel inside. Then, the horizontal hydraulic rod 6 is stopped, and the cooled mold steel can be taken out. This is the working principle of the mold steel rapid quenching processing device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
