Description

Technical Field

[0001] This utility model relates to the technical field of metal heat treatment equipment, specifically to an automatic twin-shaft quenching machine. Background Technology

[0002] A quenching machine is an industrial device that uses high-frequency current (30K-1000KHZ) to locally heat and cool the surface of a metal workpiece. The skin effect generated by the alternating magnetic field rapidly heats the surface to 800-1000ºC, forming a surface hardened layer while maintaining the toughness of the core.

[0003] However, the drawbacks of traditional quenching processes are: 1. Manual heating and cooling result in unstable temperature control, which can easily lead to workpiece deformation or uneven hardness.

[0004] 2. Ordinary quenching machines can only achieve single-axis movement (such as lifting or rotating), which makes it difficult to guarantee uniform quenching of complex workpieces.

[0005] 3. The position adjustment of the induction coil depends on manual operation, resulting in low precision and poor repeatability. Utility Model Content

[0012] Furthermore, the annular spray assembly includes an annular spray pipe, the first and last ends of which are fixed to a fixed plate; and multiple nozzles are evenly arranged on the annular spray pipe.

The specific structure of this embodiment will be described in detail below.

[0023] An automatic twin-shaft quenching machine includes a frame 1.

[0024] Among them, a support plate 2 is provided in the middle of the frame 1, a liquid collection tank 3 is provided in the middle of the support plate 2, and a rotating motion component 5 for placing the workpiece 4 is provided at the protrusion in the middle of the liquid collection tank 3.

[0025] Specifically, a lifting assembly 6 is provided on the support plate 2, and an induction heating assembly and an annular spray assembly are provided on the lifting assembly 6 to act on the workpiece 4; a quenching liquid circulation assembly is provided in the frame 1 located below the support plate 2, and both the annular spray assembly and the quenching liquid circulation assembly are connected to the quenching liquid pool 10.

[0026] In this embodiment, the workpiece 4 is placed on the rotary motion component 5, and the workpiece 4 rotates at a constant speed through the rotary motion component 5. The induction heating component can induction heat the workpiece. After heating, the workpiece 4 can be sprayed by the annular spray component. The lifting component 6 can achieve precise lifting and lowering of the induction heating component and the annular spray component to ensure uniform quenching of the workpiece. This achieves dual-axis motion and realizes coordinated control of induction heating, precise lifting and lowering, and uniform rotation of the workpiece, thereby improving the uniformity and efficiency of quenching.

[0027] Specifically, the rotary motion assembly 5 includes a first motor 51 disposed in the central protrusion of the liquid collection tank 3, and a tray 52 mounted on the central protrusion of the liquid collection tank 3 via bearings; the workpiece 4 is fixed on the tray 52; the first motor 51 is rotatably connected to the tray 52 via a planetary reducer and a coupling.

[0028] In this embodiment, the first motor 51 is an existing stepper motor or servo motor. The liquid collection tank 3 is an annular groove with a central protrusion. The first motor 51 is located inside the central protrusion. The tray 52 is mounted above the central protrusion of the liquid collection tank 3 through bearings. Furthermore, the first motor 51 is rotatably connected to the tray 52 through a planetary reducer and a coupling. The first motor 51 drives the tray 52 to rotate at a uniform speed, thereby driving the workpiece 4 to rotate at a uniform speed.

[0029] Specifically, the lifting assembly 6 includes a second motor 61 and a KK module 62 fixed on the support plate 2. The second motor 61 is connected to the lead screw of the KK module 62 through a planetary reducer and a coupling. A fixing plate 63 is provided on the slider of the KK module 62. The induction heating assembly and the annular spray assembly are both installed on the fixing plate 63.

[0030] In this embodiment, the second motor 61 is an existing stepper motor or servo motor, and the KK module 62 is an existing HIWIN linear module, specifically the KS140-10C-600A module.

[0031] The second motor 61 is connected to the lead screw of the KK module 62 through a planetary reducer and a coupling. The second motor 61 drives the lead screw of the KK module 62, causing the slider of the KK module 62 to move up and down. This, in turn, drives the fixed plate 63 to move up and down, and in turn drives the induction heating component and the annular spray component to move up and down.

[0032] Specifically, the induction heating component includes an induction coil 7; the induction coil 7 is ring-shaped, with its first and last ends fixed on a fixing plate 63.

[0033] In this embodiment, the induction coil 7 is made of a rectangular copper tube, and its inner contour maintains an equidistant gap of 3-10mm with the outer shape of the workpiece 4. The induction coil 7 is connected to an external high-frequency power supply.

[0034] Specifically, the annular spray assembly includes an annular spray pipe 81, the first and last ends of which are fixed on the fixing plate 63; multiple nozzles are evenly arranged on the inner side of the annular spray pipe 81, with the nozzles facing the workpiece 4. The first and last ends of the annular spray pipe 81 pass through the fixed plate 63 and are connected to one end of the high-pressure liquid pump 82 through a hose; the other end of the high-pressure liquid pump 82 is connected to the quenching liquid pool 10 through a pipe.

[0035] In this embodiment, the first and last ends of the annular spray pipe 81 are fixed on the fixing plate 63. The quenching liquid in the quenching liquid pool 10 is drawn into the annular spray pipe 81 by the high-pressure liquid pump 82 and sprayed onto the workpiece 4 through the nozzle.

[0036] Optionally, the nozzle can be selected as an adjustable spray angle nozzle. The high-pressure liquid pump 82 uses an existing magnetic drive pump, specifically model 14CQ-5P.

[0037] Specifically, the lifting trajectories of the induction coil 7 and the annular spray pipe 81 are arranged coaxially with the rotation axis of the tray 52, and the annular spray pipe 81 is located below the induction coil 7.

[0038] Specifically, the quenching fluid circulation assembly includes a heat exchanger 9. The heat medium inlet of the heat exchanger 9 is connected to the outlet 31 of the collection tank 3 via a pipe, and the heat medium outlet of the heat exchanger 9 is connected to the quenching fluid pool 10 via a pipe. A filter screen is installed at the outlet 31 of the collection tank 3. The quenching fluid is filtered through the filter screen to prevent impurities from entering the heat exchanger 9.

[0039] In this embodiment, the heat exchanger 9 is an existing type, specifically model WKS52-04. The refrigerant inlet and refrigerant outlet of the heat exchanger 9 are connected to external cooling water through pipes to form a circulating water path. Thus, the quenching liquid collected in the liquid collection tank 3 is cooled by cooling water in the heat exchanger 9, and the cooled quenching liquid is returned to the quenching liquid pool 10.
