Description

Technical Field

[0001] This application relates to the field of high-frequency heat treatment technology, specifically a high-frequency heat treatment apparatus. Background Technology

[0002] High-frequency heat treatment is an advanced metal processing technology. Based on the principle of electromagnetic induction, it uses high-frequency current to generate induced current on the surface of the workpiece to achieve rapid heating, and combines it with cooling treatment to give metal materials new performance characteristics.

[0003] For example, the patent with publication number CN211445816U discloses a high-frequency quenching device based on heat treatment processing. The device clamps the workpiece by tightening the clamping parts and moves it into the heating coil of the high-frequency quenching machine for heating. When the temperature is heated to a suitable temperature, the drive motor drives the screw to rotate, which causes the clamping parts to contract. At this time, the workpiece falls under the influence of gravity and enters the cooling box through the dropping groove to cool the workpiece.

[0004] However, although the above-mentioned patent can achieve quenching and cooling of workpieces, its cooling method is to drop the workpiece directly into the cooling pool and cool it by immersion. Although the immersion cooling speed is relatively fast, it may cause large internal structural stress in the workpiece, or even cause cracking, thus affecting the quality of some precision parts.

[0005] Therefore, it is necessary to provide a high-frequency heat treatment device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figures 1-2 As shown, this application provides a high-frequency heat treatment apparatus, including a base 1, on which a clamping assembly 2 is disposed. The clamping assembly 2 is used to clamp workpieces, such as shaft-type mechanical parts. Specifically:

[0030] The clamping assembly 2 includes a fixed box 21 fixedly mounted on the base 1. The fixed box 21 is made of multiple steel plates, and a moving module (not shown in the figure) is provided inside the fixed box 21. The moving module uses existing ball screws and linear guides as transmission mechanisms and a drive device as a power source. The drive device can be an electric motor or a hydraulic motor. The specific structure and working principle are existing technologies and will not be described in detail here.

[0031] The fixed box 21 has an opening (not shown in the figure), and an elastic pad 22 is provided at the opening to seal the opening. A fixed plate 23 is provided on the elastic pad 22. The fixed plate 23 is connected to the output end of the moving module, and then the fixed plate 23 is driven up and down by the moving module.

[0032] It should be noted that the elastic pad 22 has multiple sets of corrugated folds, which can cause the elastic pad 22 to stretch or contract when the fixed plate 23 moves.

[0033] A mounting plate 25 is fixedly installed on one side of the mounting plate 23. A cylinder 24 is fixedly installed on the top of the mounting plate 25, and an upper tip 26 is fixedly installed at the output end of the cylinder 24. The upper tip 26 penetrates the mounting plate 25 so that the upper tip 26 can extend or retract under the drive of the cylinder 24.

[0034] Continue to refer to Figure 2 A base plate 28 is fixedly installed at the bottom of the fixed plate 23. A protective box 29 is fixedly installed on the base plate 28. A motor (not shown in the figure) is installed inside the protective box 29, and a lower tip 27 is fixedly installed at the output end of the motor. One end of the lower tip 27 extends out of the protective box 29.

[0035] When it is necessary to clamp the workpiece, place the lower end of the workpiece on the lower center 27, and start the cylinder 24 to drive the upper center 26 to move downward until it abuts against the upper end of the workpiece to clamp both ends of the workpiece. Then, start the moving module to drive the fixed plate 23 to move, thereby driving the upper center 26 and the lower center 27 to move, and then driving the workpiece to move as a whole.

[0036] A quenching component 3 is provided on the base 1, which is used for quenching the workpiece.

[0037] like Figures 1-2 As shown, the quenching assembly 3 includes a water tank 31 fixedly installed on the base 1. The water tank 31 has a notch (not shown in the figure) that is adapted to the fixing box 21. The fixing box 21 is located at the notch to facilitate sealing of the water tank 31. The bottom plate 28 is located inside the water tank 31. At the same time, a pad 33 is fixedly installed inside the water tank 31. The pad 33 is made of multiple sets of steel plates spliced ​​together to facilitate the installation of subsequent equipment.

[0038] Furthermore, an induction coil 34 is provided on the pad 33. The two ends of the induction coil 34 are connected to an external high-frequency device to provide power to the induction coil 34. The induction coil 34 has a coil part, and the lower tip 27 is on the same axis as the coil part. In the initial state, the top of the lower tip 27 exposes the coil part so that the workpiece after clamping can pass through the coil part to heat the workpiece when it moves with the upper tip 26 and the lower tip 27.

[0039] Meanwhile, a support plate 32 is fixedly installed at the bottom of the pad 33. A ring 35 is fixedly installed at the end of the support plate 32 away from the pad 33. Multiple sets of connecting blocks 4 are fixedly installed on the ring 35, and a water spray cylinder 37 is arranged between the multiple sets of connecting blocks 4. A hose 38 is provided on the water spray cylinder 37. The hose 38 can be connected to an external water supply device to facilitate pouring coolant into the water spray cylinder 37.

[0040] like Figures 3-4 As shown, multiple sets of spray holes 39 are provided on the inner wall of the water spray cylinder 37. These spray holes 39 are arranged in a circular pattern, and the spray holes 39 extend from... Figure 3 In the middle, from top to bottom, the diameter gradually increases to facilitate the spraying of coolant from the spray hole 39, and its flow rate gradually increases to perform step-by-step cooling when cooling the workpiece;

[0041] Multiple sets of electric cylinders 41 are fixedly installed on the ring 35. A connecting ring 36 is installed at the output end of the electric cylinder 41. Multiple sets of connecting plates 42 are installed at the bottom of the connecting ring 36. A hinge block 43 is hinged to the bottom of the connecting plate 42. At the same time, multiple sets of supports 47 are fixedly installed at the bottom of the ring 35. A hinge block 43 is rotatably installed at the bottom of the support 47. One end of the hinge block 43 is hinged to the bottom of the connecting plate 42.

[0042] So that the connecting ring 36 can be moved by the electric cylinder 41, thereby driving the hinge block 43 to rotate along its hinge point with the support 47 through the connecting plate 42.

[0043] Meanwhile, two sets of limiting rods 46 are provided on the hinge block 43, and a straight plate 44 is provided between the two sets of limiting rods 46. The straight plate 44 is located between the two sets of limiting rods 46 and has a certain gap with the two sets of limiting rods 46. The top of the straight plate 44 is hinged to the bottom of the ring 35. A nozzle 45 is provided at the bottom of the straight plate 44. The nozzle 45 can be connected to an external water supply device through a hose 38 to cool the workpiece. When the hinge block 43 rotates, the nozzle 45 can be rotated by the cooperation of the limiting rods 46 and the straight plate 44, thereby adjusting the angle of water spray to adapt to some shaft parts with irregular curved surfaces.

[0044] In summary, during use, the bottom end of the workpiece is placed on the lower center 27, and then the cylinder 24 is activated to drive the upper center 26 to move downward, thereby clamping both ends of the workpiece. Then, the moving module drives the fixing plate 23 to move downward, thereby driving the workpiece downward through the upper center 26 and the lower center 27, so that the workpiece passes through the coil part of the induction coil 34. The quenching component 3 is then activated to quench the workpiece, and the workpiece is cooled through the water spray hole 39 and the nozzle 45.

[0045] It should be noted that during the quenching process, the motor can be started to drive the lower center 27 to rotate, thereby driving the workpiece to rotate, so as to heat the workpiece evenly. The nozzle 45 can also be adjusted to a certain angle to rinse the lower center 27 and the base plate 28.
