Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter manufacturing technology, and in particular to a heat treatment device for milling cutter manufacturing. Background Technology
[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Existing milling cutters have an internal cooling effect, and during the production process, external heat treatment is required. Current heat treatment processes for milling cutters are usually annealing, quenching, and tempering. Among them, milling cutter annealing uses high temperature and time to act on the tool, causing changes such as recrystallization and grain boundary movement in its grain structure, thereby eliminating internal stress and improving properties such as hardness and toughness.
[0003] Although end mill annealing is simple, there are some things to pay attention to in order to ensure the annealing effect and tool quality. For example, the tool needs to be fully pre-treated before annealing, such as removing the surface oxide layer, oil stains and grinding marks, to ensure that the tool surface is smooth. If it is not cleaned, it will have an adverse effect on the subsequent end mill annealing. The existing end mill cleaning methods are partly manual cleaning one by one, which is time-consuming, labor-intensive and has low automation.
[0004] Therefore, it is necessary to provide a heat treatment apparatus for milling cutter production to solve the above-mentioned technical problems. Utility Model Content

The top of the vertical part of the bracket is connected to the top of the support base. A drain hole is provided on the side of the cleaning cylinder above the placement plate, and the drain hole is connected to a drain pipe via a solenoid valve.
[0007] Preferably, the bottom of the placement plate is provided with a mounting groove, and the top of the conduction plate is provided with a mounting shaft that mates with the mounting groove.

The inner diameter of the fixing holes on different placement plates is different. The number of cleaning plates is the same as the number of placement plates and corresponds one-to-one. The inner diameter of the cleaning brushes on different cleaning plates is different.
[0009] Preferably, the peripheral surface of the cleaning plate is connected to a plurality of guide blocks, the guide blocks are slidably connected to guide grooves, the guide grooves are disposed on the inner wall of the cleaning cylinder and the top of the guide grooves extends to the top of the cleaning cylinder.
[0010] Preferably, a sealing ring made of rubber is bonded to the inner wall of the fixing hole.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] refer to Figures 1 to 4 This utility model provides a heat treatment device for milling cutter production, including a support base 1, a heating box for annealing milling cutters, and a cleaning cylinder 2 installed on one side of the heating box. The cleaning cylinder 2 is installed on the top of the support base 1. A conduction plate 20 is installed inside the cleaning cylinder 2. The top of the conduction plate 20 is movably connected to the bottom of a placement plate 13. The placement plate 13 has multiple fixing holes 14 inside. An electromagnet 22 is installed at the bottom of the conduction plate 20 directly below the fixing holes 14. A cleaning plate 6 is provided above the cleaning cylinder 2. The top of the cleaning plate 6 has multiple cleaning holes 7. An annular cleaning brush 8 is installed on the inner wall of the cleaning holes 7. The top of the cleaning plate 6 is connected to the telescopic end of an electro-hydraulic device 10. The fixed end of the electro-hydraulic device 10 is connected to the bottom end of the horizontal part of an L-shaped bracket 11. The top of the vertical part of the bracket 11 is connected to the top of the support base 1. A drain hole is provided on the side of the cleaning cylinder 2 above the placement plate 13. The drain hole is connected to a drain pipe 4 through a solenoid valve 3.
[0024] It should be noted that the heating chamber uses an existing device for annealing cutting tools, which is existing technology and will not be described in detail here.
[0025] Before annealing, the cutting tool can be pre-treated. The size of the fixing hole 14 on the placement plate 13 is matched with the milling cutter to be annealed. The fixing hole 14 is movably connected to the lower end of the milling cutter. At this time, the bottom of the milling cutter is in contact with the conduction plate 20. By activating the electromagnet 22, the bottom of the milling cutter is attracted by the magnetism of the electromagnet 22, and the milling cutter is fixed on the inner side of the placement plate 13. Then, cleaning fluid is poured into the inner side of the cleaning cylinder 2. The oil stains are softened by soaking in the cleaning fluid. Then, the cleaning plate 6, which moves up and down, is driven by the electro-hydraulic device 10. The cleaning brush 8 inside the cleaning hole 7 on the cleaning plate 6 is used to wash the outer surface of the cutting tool to remove oil stains and foreign objects. After washing, the cleaning plate 6 returns to its original position by the drive of the electro-hydraulic device 10. Then, the drain hole is opened by opening the solenoid valve 3, and the sewage is discharged through the drain pipe 4.
[0026] With the above structure, the milling cutter can be fully pre-treated by the cleaning cylinder 2 before annealing to remove the oxide layer and oil stains on the surface of the milling cutter, so as to ensure that the surface of the tool is smooth. By setting multiple fixing holes 14, multiple milling cutters can be fixed at the same time, thereby realizing the cleaning operation of multiple milling cutters at the same time, eliminating the need for manual cleaning one by one, and effectively improving the cleaning efficiency.
[0027] In the embodiments of this utility model, reference is made to Figure 3 , Figure 4 As shown, the bottom of the placement plate 13 is provided with a mounting groove 23, and the top of the conduction plate 20 is provided with a mounting shaft 21 that cooperates with the mounting groove 23.
[0028] In the embodiments of this utility model, reference is made to Figure 2 As shown, there are multiple placement plates 13, and the different placement plates 13 are the same size, and the position and number of fixing holes 14 are the same. The inner diameter of the fixing holes 14 of the different placement plates 13 is different. The number of cleaning plates 6 is the same as the number of placement plates 13 and corresponds one-to-one. The inner diameter of the cleaning brush 8 of the different cleaning plates 6 is different.
[0029] It should be noted that by setting the mounting groove 23 and the mounting shaft 21, the mounting groove 23 and the mounting shaft 21 can be connected to each other, which facilitates the connection between the placement plate 13 and the transmission plate 20. In subsequent replacements, it is easy to remove the placement plate 13 from the transmission plate 20. By setting multiple placement plates 13 with fixing holes 14 of different sizes, the appropriate placement plate 13 can be selected according to the different sizes of the milling cutter, and the corresponding cleaning plate 6 can be selected according to the placement plate 13, thereby improving the applicability of the device.
[0030] In the embodiments of this utility model, reference is made to Figure 1 As shown, the peripheral surface of the cleaning plate 6 is connected with a plurality of guide blocks 9, the guide blocks 9 are slidably connected to the guide groove 5, the guide groove 5 is disposed on the inner wall of the cleaning cylinder 2 and the top of the guide groove 5 extends through to the top of the cleaning cylinder 2.
[0031] It should be noted that by setting the guide block 9, the cleaning plate 6 moves downward, and the guide groove 5 provides limiting guidance, which effectively improves the stability of the cleaning plate 6 when it moves downward.
[0032] In the embodiments of this utility model, reference is made to Figure 2 As shown, a sealing ring 15 made of rubber is bonded to the inner wall of the fixing hole 14.
[0033] It should be noted that by setting the sealing ring 15, the elasticity of the sealing ring 15 can be used to make the sealing ring 15 tightly connected to the outer surface of the milling cutter, thereby improving the tightness of the connection between the fixing hole 14 and the milling cutter.
[0034] In the embodiments of this utility model, reference is made to Figure 3 As shown, the inner wall of the cleaning cylinder 2 has multiple drying grooves 18, an electric heating plate 19 is installed inside the drying groove 18, and a heat-conducting plate 12 is installed at the end of the drying groove 18 facing the inside of the cleaning cylinder 2.
[0035] It should be noted that by setting up the drying tank 18, heat can be transferred to the interior of the cleaning cylinder 2 through the heating of the electric heating plate 19 after cleaning, thereby drying the milling cutter after cleaning. By setting up the heat conducting plate 12, the drying tank 18 can be sealed without affecting the heat transfer of the electric heating plate 19, preventing the cleaning liquid from entering the drying tank 18 during cleaning and affecting the electric heating plate 19.
[0036] In the embodiments of this utility model, reference is made to Figure 2 As shown, the top two ends of the placement plate 13 are vertically connected to the first lifting ring 16 and the second lifting ring 17, and the first lifting ring 16 and the second lifting ring 17 are both U-shaped.

[0039] The end mill is movably connected to the lower end of the milling cutter through the fixing hole 14. At this time, the bottom of the milling cutter is in contact with the conduction plate 20. By activating the electromagnet 22, the bottom of the milling cutter is attracted by the magnetism of the electromagnet 22, and the milling cutter is fixed inside the placement plate 13. Then, cleaning fluid is poured into the inside of the cleaning cylinder 2. The oil stains are softened by soaking in the cleaning fluid. Then, the cleaning plate 6, which moves up and down, is driven by the electro-hydraulic device 10. The cleaning brush 8 inside the cleaning hole 7 on the cleaning plate 6 washes the outer surface of the tool, removing oil stains and foreign objects. After washing, the cleaning plate 6 returns to its original position by the drive of the electro-hydraulic device 10. Then, the drain hole is opened by opening the solenoid valve 3, and the sewage is discharged through the drain pipe 4.
