Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and more specifically, to a rapid cyclic quenching device for ultra-fine hot work die steel. Background Technology

[0002] Hot work die steel refers to steel used to manufacture hot working dies such as hot forging dies, hot extrusion dies, and die casting dies. It has good hot strength, wear resistance, corrosion resistance, and resistance to thermal fatigue. Ultra-fine hot work die steel quenching refers to the process of using a heat treatment process that rapidly heats and cools hot work die steel to obtain a fine martensite or bainite structure, thereby further improving its strength, toughness, wear resistance, and resistance to thermal fatigue.

[0003] A search revealed that Chinese patent CN220224231U discloses a quenching device for mold steel. A lifting mechanism drives a lifting plate downwards, which in turn moves a sliding frame. The sliding frame then moves a contact plate, which in turn moves a steel column, placing the column inside a heating coil. The heating coil is activated to heat the column. A temperature monitor is installed on the mounting frame. Once the quenching temperature is reached, the heating coil is turned off. The lifting plate continues to drive the sliding frame downwards, pushing the steel column into a cooling pool containing coolant for rapid cooling and quenching.

[0004] When the above-mentioned quenching device is used for hot work die steel, it heats the hot work die steel with a heating coil and cools it rapidly with a coolant. However, when cooling one hot work die steel, it is inconvenient to heat the other hot work die steel, which reduces the overall quenching efficiency of the hot work die steel. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid cyclic quenching device for ultra-fine hot work die steel, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid cyclic quenching device for ultra-fine hot work die steel, comprising a support frame, a heating furnace, a cooling cylinder, and a storage frame. The heating furnace, cooling cylinder, and storage frame are all fixedly installed at the top of the support frame. A U-shaped plate is fixedly connected to the inner top of the support frame. An adjustment assembly is provided on the U-shaped plate. The adjustment assembly includes a first stepper motor, a gear rod, a gear ring, a vertical cylinder, and a circular plate. The first stepper motor is fixedly installed at the bottom of the U-shaped plate, and the output shaft end of the first stepper motor is fixedly connected to the gear rod. The gear rod meshes with the gear ring, and the gear ring is fixedly sleeved on the vertical cylinder. The top of the vertical cylinder is fixedly connected to the circular plate, and the outer side of the vertical cylinder is movably connected to the support frame via a bearing. Two hydraulic cylinders are fixedly installed at the bottom of the circular plate, and hydraulic grippers are fixedly installed at the bottom of each of the two hydraulic cylinders.

[0007] Furthermore, each of the two hydraulic grippers has an air outlet movably installed on the opposite side, and the opposite ends of the two air outlets are fixedly connected to the vertical cylinder.

[0008] It can be seen that the above technical solution allows for air cooling of the two hot work die steels.

[0009] Furthermore, a cooler is fixedly installed on one side of the support frame, and multiple heat-conducting columns are movably arranged on one side of the cooler, with all the heat-conducting columns fixedly installed on the top of the support frame.

[0010] Furthermore, a rotating assembly is provided at the bottom of the vertical cylinder. The rotating assembly includes a second stepper motor, a first rotating shaft, a fan blade, a second rotating shaft, a stirring rod, and a toothed belt. The second stepper motor is fixedly installed inside the bottom of the support frame, and the output shaft end of the second stepper motor is fixedly connected to the first rotating shaft.

[0011] Furthermore, the top end of the first rotating shaft is fixedly connected to the fan blade, and the first rotating shaft and the second rotating shaft are connected by a toothed belt. The second rotating shaft is movably connected to the top end of the support frame by a bearing, and the top end of the second rotating shaft is fixedly connected to the stirring rod.

[0012] Furthermore, filters are fixedly embedded on both sides of the support frame near the bottom edge.

[0013] As can be seen, the above technical solution aims to prevent dust from entering the support frame.

[0014] Furthermore, fixing plates are fixedly connected to the bottom edges of both sides of the support frame.

[0015] As can be seen, in the above technical solution, bolts are used to easily fix the fixing plate, thereby fixing the support frame.

[0016] The technical effects and advantages of this utility model are as follows: 1. This utility model uses hydraulic grippers to clamp ultra-fine hot work die steel blanks, heats the ultra-fine hot work die steel blanks in a heating furnace, and adjusts the components to position the ultra-fine hot work die steel blanks at the top of the cooling cylinder. The coolant in the cooling cylinder rapidly cools the ultra-fine hot work die steel blanks. Similarly, another hydraulic gripper clamps another ultra-fine hot work die steel blank, and so on, which can be repeated to quickly quench the steel, effectively improving the overall quenching efficiency of hot work die steel. 2. This utility model uses a refrigeration unit to cool the inside of the support frame, and multiple heat-conducting columns to cool the coolant in the cooling cylinder. The second stepper motor drives the first rotating shaft to rotate, which in turn drives the fan blades to rotate. At the same time, the first rotating shaft drives the second rotating shaft and the stirring rod through a toothed belt. The stirring rod stirs the coolant in the cooling cylinder, so that the coolant can be cooled quickly. The structure is simple and easy to use. Attached Figure Description
