Technical Field

[0001] The invention relates to the technical field of quenching devices, and in particular to a quenching device for high-precision mold manufacturing. Background Art

[0002] The high-precision mold reproduction process needs to go through the quenching process. Quenching is a heat treatment process method that heats the steel to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite. Quenching is the most widely used process method in steel heat treatment.

[0003] In the prior art, most of the hoisted steel materials are directly placed into the quenching tank for quenching. If the steel materials move down in the quenching tank too quickly, high-temperature water vapor will be emitted and hot water will splash, which can endanger the safety of surrounding workers.

A quenching device for high-precision mold manufacturing is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A quenching device for high-precision mold manufacturing, comprising a box body and a convex block, wherein two convex blocks are respectively fixedly connected to the inner wall of the box body;

[0007] A flow-disturbing component is installed in the box body, and the flow-disturbing component includes an air-collecting chamber, a transverse chamber, a circular chamber, a rotating rod, and a stirring blade. The air-collecting chamber is fixedly connected to one of the side walls of the box body, and a plurality of the transverse chambers all penetrate one of the side walls of the box body, and one end of each of the transverse chambers is connected to the air-collecting chamber, and a plurality of the circular chambers are respectively connected to the transverse chambers, one end of each of the rotating rods is rotatably connected to the circular chamber, and an annular array impeller is provided at the lower end of the rotating rod, and the impeller is arranged in the circular chamber, and a plurality of the stirring blades are fixedly connected to the upper end of the rotating rod, and a one-way valve is installed in the transverse chamber;

[0008] Buffer components are respectively installed at both ends of the box body, and the buffer components include a placement plate, a movable plate, a closed cavity, and a lower plate. The placement plate is slidably connected to the inner wall of the box body, and the two closed cavities are respectively fixedly connected to the upper ends of the sealed cavities.

[0009] Preferably, the spoiler component also includes a sealed cavity, an L-shaped cavity, and a piston. The two sealed cavities are respectively fixedly connected to the two ends of the box body. A vent hole is opened at the upper end of the closed cavity. The piston is slidably connected in the sealed cavity. The two L-shaped cavities are fixedly connected between the sealed cavity and the air collecting cavity.

[0010] Preferably, the buffer component also includes a baffle and a spring, the baffle is fixedly connected between the closed cavity and the sealed cavity, the two springs are respectively fixedly connected between the movable plate and the box body, a push plate is fixedly connected to the piston, the push plate passes through the baffle and is fixedly connected to the lower plate.

[0011] Preferably, a fixing cavity is provided on one side wall of the box body, a sliding groove is provided on the fixing cavity, and a support rod is slidably connected in the sliding groove.

[0012] Preferably, a square plate is fixedly connected to the upper end of the support rod, a round hole is opened on the square plate, a fan blade is installed in the round hole, and a collecting chamber is fixedly connected to one side of the square plate, and the collecting chamber is communicated with the round hole.

[0013] Preferably, a rotating shaft is rotatably connected to the fixed cavity, a thread is formed on the rotating shaft, the thread is arranged in the sliding groove, and the support rod is threadably connected to the rotating shaft.

[0014] Preferably, a gear is fixedly connected to one end of the rotating shaft, a connecting plate is fixedly connected to one of the movable plates, the connecting plate is L-shaped, a tooth pattern is formed at one end of the connecting plate away from the movable plate, and the connecting plate is meshingly connected to the gear.

At the same time, the servo motor is driven to drive the fan blades in the square plate to rotate, so that the high-temperature water vapor generated by the high-precision mold during the quenching process can be sucked into the collection cavity. As the square plate reciprocates, it can drive the fan blades to suck in water vapor in a larger range.

[0019] When the moving plate moves downward, it can drive the lower plate to move downward in the closed cavity, so that when the lower plate moves downward, the liquid on the lower side can flow to the upper side through the circular hole, which can slow down the downward movement speed of the lower plate and the moving plate, and also slow down the downward movement speed of the placement plate and the high-precision mold in the box, thereby avoiding the liquid in the lower box of the high-precision mold from moving down too quickly and causing splashing of high-temperature liquid.

[0020] The gas in the horizontal cavity can push the impeller in the circular cavity and drive the rotating rod to rotate. When the stirring blade rotates with the rotating rod, it can have a disturbing effect on the liquid in the box, so that the high-precision mold on the placement plate can better contact with the liquid in the box to complete quenching.

[0032] In the present invention, when in use, the hoisted high-precision mold is placed on the placement plate 3, and the placement plate 3 moves downward due to the weight of the high-precision mold, and drives the movable plate 7 to move downward, and at the same time the spring 4, the high-precision mold can be moved down to the liquid in the box body 1 for quenching, when the connecting plate 8 moves down with the movable plate 7, it can drive the gear 12 to rotate, and when the rotating shaft 11 rotates with the gear 12, it can drive the square plate 13 to move horizontally back and forth on the fixed cavity 2, and at the same time drive the servo motor to drive the fan blades in the square plate 13 to rotate, so that the high-temperature water vapor generated by the high-precision mold during the quenching process can be sucked into the collection cavity 14, and the reciprocating movement of the square plate 13 can drive the fan blades to inhale water vapor in a better range.

Since the closed cavity 9 is filled with liquid, when the lower plate 17 moves downward, the liquid on the lower side can flow to the upper side through the circular hole, so that the downward speed of the lower plate 17 and the movable plate 7 can be slowed down. It can also slow down the speed of the placement plate 3 and the high-precision mold moving downward in the box body 1, thereby avoiding the liquid in the lower box body 1 of the high-precision mold moving downward too quickly and causing splashing of high-temperature liquid.

At this time, the gas in the gas collecting chamber 15 can push the one-way valve to open and flow into the transverse chamber 25 respectively. The gas in the transverse chamber 25 can push the impeller in the circular chamber 24 and drive the rotating rod 23 to rotate. When the stirring blade 22 rotates with the rotating rod 23, it can have a disturbing effect on the liquid in the box body 1, so that the high-precision mold on the placement plate 3 can better contact with the liquid in the box body 1 to complete the quenching. When the high-precision mold is lifted after the quenching is completed, the placement plate 3 is no longer squeezed. The placement plate 3 moves up and is attached under the pulling force of the spring 4 to prepare for the subsequent quenching of the high-precision mold.
