Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutters, and in particular relates to a quenching device used for milling cutter processing. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in sequence. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. When optimizing the milling effect, the blade of the milling cutter is another important factor. If more than one blade participates in cutting at any time, it is an advantage, but too many blades participate in cutting at the same time is a disadvantage. When cutting, each cutting edge cannot cut at the same time. The required power is related to the number of cutting edges participating in cutting. In terms of chip formation process, cutting edge load and processing results, the position of the milling cutter relative to the workpiece plays an important role.

[0003] Quenching is a heat treatment process. Quenching steel is a heat treatment process that heats the steel to a temperature above the critical temperature, keeps it warm for a period of time, makes it fully or partially austenitized, and then rapidly cools it at a cooling rate greater than the critical cooling rate. By quenching the milling cutter, the hardness of the milling cutter can be increased, making it less prone to wear and tear, which is conducive to making the milling cutter more durable. When quenching, the milling cutter is mostly heated by a heating device first. However, when the existing heating equipment heats the milling cutter, the temperature of various parts of the milling cutter surface is inconsistent, which is prone to uneven heating temperature of the milling cutter surface. The problem addressed by this device is how to make the heating temperature of the milling cutter surface more uniform. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5The utility model provides the following technical solutions: a quenching device for milling cutter processing, comprising a main body box 1, a fixed plate 8 is fixedly installed in the middle of the top of the main body box 1, a cylinder 13 is fixedly installed on one side of the fixed plate 8, a gas rod 7 is fixedly installed on the output end of the cylinder 13, a movable plate 15 is fixedly installed on one end of the gas rod 7, a connecting plate 22 is fixedly installed on the bottom of the movable plate 15, a fixing ring 23 is fixedly installed on the bottom of the connecting plate 22, a mounting rod 24 is fixedly installed on the top of the inner wall of the fixing ring 23, a threaded rod 25 is threadedly connected to the surface of the fixing ring 23, and a movable knob 26 is fixedly installed on one end of the threaded rod 25, a DC power supply 2 is fixedly installed on the left side of the main body box 1, a second connecting rod 19 and a first connecting rod 17 are fixedly installed on one side of the DC power supply 2, a spiral coil 18 is arranged inside the main body box 1, and the front end of the spiral coil 18 is fixedly connected to the second connecting rod 19, and the tail end of the spiral coil 18 is fixedly connected to the first connecting rod 17, and the right side of the main body box 1 is open.

[0023] Since the threaded rod 25 is threadedly connected with the fixing ring 23, the threaded rod 25 can be driven to rotate by the movable knob 26, so that one end of the milling cutter can be clamped and fixed between the mounting rod 24 and the threaded rod 25, and then the cylinder 13 is started to drive the movable plate 15, the connecting plate 22 and the fixing ring 23 to move through the air rod 7, so that the milling cutter can be moved to the inside of the spiral coil 18, and the spiral coil 18 can be energized by the DC power supply 2, the first connecting rod 17 and the second connecting rod 19. By energizing the spiral coil 18, a high-frequency magnetic field can be generated in the spiral coil 18, so that the milling cutter in The milling cutter inside the spiral coil 18 is heated by the magnetic field induction. This device is a heating method that converts electrical energy into magnetic energy to generate induced eddy currents on the surface of the milling cutter. Compared with the traditional conduction heating method, the heating efficiency is higher. The milling cutter is located inside the spiral coil 18, and the milling cutter and the spiral coil 18 have no contact, which is conducive to keeping the heating temperature of the milling cutter surface consistent, making the heating temperature of the milling cutter surface more uniform. After the milling cutter is moved to the inside of the spiral coil 18, the drive motor 20 can be started to drive the gear 21 to rotate through the rotating shaft at the output end. Since the gear 21 is meshed and connected with the rack plate 10, When the gear 21 rotates, the rack plate 10 and the movable cover 5 can be driven to move, so that the movable cover 5 can be buckled on the right side of the main box 1 to avoid the problem of temperature loss inside the main box 1. When the movable cover 5 needs to be removed, the drive motor 20 is started to drive the gear 21 to rotate in the reverse direction. Since the control switch 3 and the adjustment knob 4 are electrically connected to the uniform DC power supply 2, the control switch 3 can be used to control whether the spiral coil 18 is energized, and the adjustment knob 4 can be used to adjust the current of the spiral coil 18. The current determines the strength of the magnetic field, and the strength of the magnetic field determines the heating temperature, which is beneficial to improving the device. The display screen 9 can display the temperature inside the main box 1 for the convenience of observation and regulation by the user. The setting of the support rod 16 and the support plate 11 can facilitate the device to be placed horizontally on the ground. Since the bottom of the support plate 11 is frosted, the friction between the bottom of the support plate 11 and the ground can be increased, making it difficult for the device to slide on the ground. As for the setting of the mounting plate 14, since the surface of the gas rod 7 is movably connected to the mounting plate 14, it can play a certain supporting role on the gas rod in the process of keeping the gas rod moving. All electrical equipment in this device are powered by an external power supply.

[0024] In one aspect of the present embodiment, after the milling cutter is moved to the inside of the spiral coil 18, the drive motor 20 can be started to drive the gear 21 to rotate through the rotating shaft at the output end. Since the gear 21 is meshed and connected with the rack plate 10, when the gear 21 rotates, it can drive the rack plate 10 and the movable cover 5 to move, so that the movable cover 5 can be buckled on the right side of the main box 1 to avoid the problem of temperature loss inside the main box 1. When the movable cover 5 needs to be removed, the drive motor 20 is started to drive the gear 21 to rotate in the reverse direction.

[0025] In one aspect of the present embodiment, the arrangement of the support rod 16 and the support plate 11 can facilitate the device to be placed horizontally on the ground, and since the bottom of the support plate 11 is frosted, the friction between the bottom of the support plate 11 and the ground can be increased, making it difficult for the device to slide on the ground. As for the arrangement of the mounting plate 14, since the surface of the gas rod 7 is movably connected to the mounting plate 14, it can play a certain supporting role on the gas rod while keeping the gas rod moving.

[0026] In one aspect of the present embodiment, since the control switch 3 and the adjustment knob 4 are electrically connected to the uniform DC power supply 2, the control switch 3 can be used to control whether the spiral coil 18 is energized, and the adjustment knob 4 can be used to adjust the current in the spiral coil 18. The current determines the strength of the magnetic field, and the strength of the magnetic field determines the heating temperature, which is beneficial to improving the adjustability of the device. The display screen 9 can display the temperature inside the main box 1 to facilitate observation and adjustment by the user.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
