Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of die steel, in particular to a heat treatment processing device for hot working die steel. Background Art

[0002] Heat treatment of mold steel is a critical process designed to improve the properties of the steel so that it can perform optimally in mold manufacturing. Heat treatment typically includes annealing, quenching, and tempering, each of which has a significant impact on the final properties of the mold steel.

[0003] For example, a heat treatment device for hot-working die steel disclosed in authorization publication number CN220503117U includes a heating furnace, a regulating assembly, and a cooling assembly. The heating furnace comprises a heating chamber and a cooling chamber, and the heating furnace is made of thermally insulating material. By adopting the above technical solution, the utility model has the following beneficial effects: after heating is completed, a sealing partition is driven upward by a first cylinder, thereby releasing the seal between the heating and cooling chambers.

[0004] Although the above patent can release the seal between the heating chamber and the cooling chamber, the bottom ends of the heating chamber and the cooling chamber are horizontal. Therefore, after the sealing partition is lifted, the water that has not been completely discharged from the cooling chamber can easily flow back into the heating chamber. The water vapor generated during the subsequent heating will cause a local cooling effect. Because water needs to absorb heat when evaporating, this local cooling will generate thermal stress in the steel, causing deformation or cracks. Utility Model Content

[0005] The purpose of the utility model is to provide a heat treatment processing device for hot working die steel to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A heat treatment box, wherein a motor is provided on the outer side of the middle part of the heat treatment box, a loading platform is provided on the middle part of the inner side of the heat treatment box, and a heater is provided on the top of the inner top of the heat treatment box;

[0009] The heat treatment box is provided with a sealing mechanism at the upper end close to the loading platform, and a clamping mechanism is provided at the middle of the loading platform;

[0010] A tray with holes is provided at the lower part of the heat treatment box, and cooling mechanisms are provided at the lower part of the heat treatment box near the tray with holes and at both sides of the upper end.

[0011] Preferably, the sealing mechanism includes a lifting cylinder symmetrically arranged on both sides of the top of the heat treatment box, and a sealing plate is arranged at the output shaft end of the lifting cylinder;

[0012] Preferably, the clamping mechanism includes a mounting frame symmetrically arranged on the outer sides of both sides of the loading platform. A clamping cylinder is arranged on the outer side of the middle of the mounting frame. Guide grooves are symmetrically arranged on both sides of the top of the loading platform. A clamping plate is arranged at one end of the output shaft of the clamping cylinder located inside the guide groove;

[0013] Preferably, the cooling mechanism includes a submersible pump fixedly installed below the inside of the heat treatment box. The water inlet end of the submersible pump is connected to a water suction pipe, and the water outlet end of the submersible pump is connected to a water outlet pipe through a three-way connection. Both ends of the water outlet pipe pass through both sides of the perforated tray and are connected to spray pipes. A cold water inlet and a cold water outlet are sequentially arranged from top to bottom on the front lower part of the heat treatment box;

[0014] Preferably, a fan is arranged at the inner wall of the upper part of the heat treatment box close to the spray pipe;

[0015] Preferably, a box door one and a box door two are respectively arranged at the upper and lower parts of the heat treatment box close to the motor.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For this heat treatment processing device for hot work die steel, through the cooperation of the heat treatment box, motor, loading platform, lifting cylinder, mounting frame and sealing plate, after the treatment is completed, start the two lifting cylinders. The lifting cylinders lift the sealing plate from the upper surface of the mounting frame, so that the loading platform can be turned over. When turning over, start the motor. The motor controls the loading platform to rotate 180°, and controls the sealing plate to descend to seal both sides of the loading platform. Then start the submersible pump. The submersible pump sucks the cooling water below the heat treatment box from the water suction pipe and sends it into the spray pipes at both ends through the water outlet pipe, and then sprays the die steel through the spray pipes for cooling treatment. In this way, during the treatment, the cooling water will not flow back.

[0018] 2. For this heat treatment processing device for hot work die steel, through the cooperation of the heat treatment box and the fan, during cooling, start the fan. The rotation directions of the two fans are opposite. The external air enters from the left side and exits from the right side, thereby taking away the generated water vapor. After cooling, open the box door two, and take out the die steel from the upper end of the perforated tray. In this way, the generated water vapor can be prevented from flowing back to the upper part, so as to achieve the purpose of facilitating dehumidification. BRIEF DESCRIPTION OF THE DRAWINGS

Then start the heater, and heat-treat the die steel through the heater. After the treatment is completed, start the two lifting cylinders 5. The lifting cylinders 5 lift the sealing plate 6 from the upper end surface of the mounting frame 7. In this way, the carrier table 3 can be turned over. When turning over, start the motor 2. The motor 2 controls the carrier table 3 to rotate 180°, and controls the sealing plate 6 to descend to seal both sides of the carrier table 3. Then start the submersible pump 11. The submersible pump 11 sucks the cooling water below the heat treatment box 1 from the water suction pipe 12 and sends it into the spray pipes 14 at both ends through the water outlet pipe 13, and then sprays the die steel through the spray pipes 14 for cooling treatment. In this way, during the treatment, the cooling water will not flow back.

[0028] As Figure 2 and Figure 4 shown, a perforated tray 4 is provided below the interior of the heat treatment box 1.

Then start the heater to heat-treat the die steel through the heater. After the treatment is completed, start the two lifting cylinders 5. The lifting cylinders 5 lift the sealing plate 6 from the upper surface of the mounting frame 7, so that the loading platform 3 can be turned over. When turning over, start the motor 2. The motor 2 controls the loading platform 3 to rotate 180°, and controls the sealing plate 6 to descend to seal both sides of the loading platform 3. Then start the submersible pump 11. The submersible pump 11 sucks the cooling water below the heat treatment box 1 from the water suction pipe 12 and sends it into the spray pipes 14 at both ends through the water outlet pipe 13, and then sprays the die steel through the spray pipes 14 for cooling treatment. At the same time, start the fans 17. The rotation directions of the two fans 17 are opposite. The external air enters from the left and exits from the right, thereby taking away the generated water vapor. After cooling, open the box door 19, and the die steel can be taken out from the upper end of the perforated tray 4.
