Description

Technical Field

[0001] This utility model belongs to the field of quenching technology, specifically relating to a quenching device for high-precision mold manufacturing. Background Technology

[0002] Quenching is a metal heat treatment process that involves heating a material above its critical temperature and then rapidly cooling it (usually with water, oil, or air) to cause a phase transformation in its internal structure, thereby increasing its hardness and strength. This process is often used to enhance the wear resistance of tools, cutters, and other workpieces, but it may reduce the toughness of the material. Therefore, quenching is often followed by tempering to balance the properties.

[0003] A known authorized patent with application number 202322287913.3 discloses a high-precision mold manufacturing quenching device, comprising a quenching box, a controller fixedly installed on the left side of the quenching box, a lifting mechanism installed at the bottom of the quenching box, four rectangularly evenly distributed support legs installed at the bottom of the lifting mechanism, pressure sensors fixedly installed at the bottom of the support legs, and a fan fixedly installed on the inner bottom wall of the quenching box; the lifting mechanism includes an adjustment box fixedly installed at the bottom of the quenching box, a dual-axis motor fixedly installed on the inner bottom wall of the adjustment box, and rotating rods fixedly connected to the output shafts on both sides of the dual-axis motor. This high-precision mold manufacturing quenching device provides an automated lifting quenching structure, preventing high-temperature water vapor generated during the quenching process from burning the user's skin, thereby effectively improving the safety of existing high-precision mold manufacturing quenching devices during use.

[0004] However, the following problems were found in the implementation of the relevant technology: the screw is arranged inside the quenching box. The liquid in the box is at a high temperature during quenching, which will cause the screw to soften or bend due to heat. In addition, the temperature is uniformly distributed by fan blades, which has low temperature uniformity.

[0005] Therefore, a quenching device for high-precision mold manufacturing is proposed to solve the above problems. Utility Model Content

[0006] This utility model proposes a quenching device for high-precision mold manufacturing, which solves the problems in related technologies where the screw is placed inside the quenching box, the liquid inside the box is at a high temperature during quenching, which causes the screw to soften or bend due to heat, and the use of fan blades for temperature uniformity results in low uniformity efficiency.

[0007] The technical solution of this utility model is as follows: a quenching device for high-precision mold manufacturing, comprising: a quenching box;

[0008] Side pipes and conveying pipes arranged on the outer wall of the quenching box, the input ends of the side pipes and conveying pipes converge at one point and extend into the interior of the quenching box;

[0009] The quenching box has multiple output ports inside, and the output ends of the side pipe and the conveying pipe are connected to the output ports.

[0010] The outer wall of the quenching box is provided with an electric actuator, and the output end of the electric actuator is provided with a holding component.

[0011] Preferably, the holding assembly includes a connecting rod, a support frame, and a push-pull structure. One end of the connecting rod is fixedly connected to the output end of the electric actuator, and the other end of the connecting rod is fixedly connected to the support frame.

[0012] Preferably, a barrier bar is arranged between two adjacent support frames, the support frames are connected by the barrier bar, and the push-pull structure is connected to the barrier bar.

[0013] Preferably, the push-pull structure includes a placement plate and connecting sleeves fixedly connected to both sides of the placement plate. The connecting sleeves are sleeved on the outer wall of the barrier bar, and the outer wall of the placement plate is provided with a push handle.

[0014] Preferably, the inner wall of the quenching box is provided with multiple sets of heating tubes and multiple temperature sensors.

[0015] Preferably, a high-temperature pump is provided at the bottom of the quenching box, and the high-temperature pump is connected to the side pipe and the delivery pipe for transporting the liquid inside the quenching box.

[0016] Preferably, the inlet of the side pipe and the delivery pipe is covered with a filter sleeve.

[0017] Preferably, the bottom of the quenching box is provided with multiple support legs.

[0018] The working principle and beneficial effects of this utility model are as follows:

[0019] By using an external electric actuator, direct contact with high-temperature liquid during quenching is avoided, which could lead to failure or deformation of the drive components. The side pipe and delivery pipe, along with the high-temperature pump, allow the liquid in the quenching chamber to be extracted and returned to the chamber, enabling the liquid to circulate and convect, thus preventing uneven temperature distribution within the chamber.

[0027] Implementation

[0028] Please see Figure 1 -4. A quenching device for high-precision mold manufacturing, comprising: a quenching box 1;

[0029] The side pipe 2 and the conveying pipe 12 arranged on the outer wall of the quenching box 1 converge at one point and extend into the interior of the quenching box 1.

[0030] The interior of the quenching box 1 has multiple output ports 15, and the output ends of the side pipe 2 and the conveying pipe 12 are connected to the output ports 15.

[0031] The outer wall of the quenching box 1 is provided with an electric push rod 4, and the output end of the electric push rod 4 is provided with a holding component.

[0032] The holding assembly includes a connecting rod 5, a support frame 11 and a push-pull structure. One end of the connecting rod 5 is fixedly connected to the output end of the electric push rod 4, and the other end of the connecting rod 5 is fixedly connected to the support frame 11.

[0033] A barrier bar 6 is arranged between two adjacent support frames 11, and the support frames 11 are connected by the barrier bar 6. The push-pull structure is connected to the barrier bar 6.

[0034] The push-pull structure includes a placement plate 7 and connecting sleeves 8 fixedly connected to both sides of the placement plate 7. The connecting sleeves 8 are sleeved on the outer wall of the barrier bar 6, and the outer wall of the placement plate 7 is provided with a push handle 9.

[0035] The inner wall of the quenching box 1 is arranged with multiple sets of heating tubes 13 and multiple temperature sensors 14.

[0036] A high-temperature pump 3 is installed at the bottom of the quenching box 1. The high-temperature pump 3 is connected to the side pipe 2 and the delivery pipe 12 to transport the liquid inside the quenching box 1.

[0037] The technical solution provided in this embodiment is as follows: In use, firstly, water quenching or oil quenching is selected, and then the quenching liquid is transported into the quenching box 1. Next, the high-temperature pump 3 is started, along with the heating pipe 13. The heating pipe 13 heats the quenching liquid. The high-temperature pump 3 draws out the quenching liquid through the side pipe 2 and the delivery pipe 12, and transports it back into the quenching box 1 through the output port 15, so that the quenching liquid inside the quenching box 1 flows, making the temperature of the quenching liquid more uniform. The temperature of the quenching liquid is monitored in real time by the temperature sensor 14. After the quenching temperature is reached, the electric push rod 4 is started to raise the support frame 11. After raising, the placement plate 7 is pulled out, and then the object to be quenched is placed on the placement plate 7. Then, it is pushed back, and the blocking rod 6 prevents the quenched part from falling into the quenching box 1. Then, the electric push rod 4 is retracted to quench the object. After quenching is completed, the electric push rod 4 is started to raise the support frame 11 again, ending the quenching. The quenched part is then taken out by pulling out the placement plate 7.

[0038] Furthermore, the inlet of the side pipe 2 and the delivery pipe 12 is covered by a filter sleeve 10.

[0039] Specifically, during quenching, the rapid temperature change causes solid substances such as oxides to fall off. The filter sleeve 10 prevents these impurities from entering the high-temperature pump 3 and damaging it.

[0040] Furthermore, the bottom of the quenching box 1 is provided with multiple support legs 16 for support.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
