Description

Technical Field

[0001] This utility model relates to the field of metal cutting milling cutter technology, and in particular to a cooling device for the production of metal cutting milling cutters. Background Technology

[0002] Metal milling cutters, as indispensable key tools in modern machining, are widely used in numerous industries such as automotive manufacturing, aerospace, and mold making. Their performance directly affects the precision, surface quality, and production efficiency of machined parts. In the production process of metal milling cutters, high temperature is one of the key factors affecting tool quality and production efficiency. During the manufacturing processes of milling cutters, such as heat treatment, forging, and cutting, a large amount of heat is generated. If this heat cannot be dissipated effectively and in a timely manner, it will cause thermal stress within the tool material, leading to defects such as tool deformation and cracking, seriously affecting the dimensional accuracy and mechanical properties of the tool.

[0003] Chinese patent application CN202323526782.6 discloses a cooling device for metal cutting milling cutter production, including a transmission vertical shaft, a first driving bevel gear, and cooling fan blades. The first driving bevel gear is located on the right side of the annular side of the transmission shaft, and the cooling fan blades are installed on the right end of the driven shaft. This device controls a multi-stage electric push rod to extend, causing the connecting rod to move the basket downwards, thereby immersing the milling cutter blank in the cooling water inside the water tank for rapid cooling. At the same time, as the drive motor drives the fan blades to rotate through the transmission shaft, the transmission shaft drives the transmission vertical shaft to rotate through the first driving bevel gear and the first driven bevel gear. The transmission vertical shaft then drives the cooling fan blades to rotate through the second driving bevel gear, the second driven bevel gear, and the driven shaft, so that the rotating cooling fan blades blow air to the right, thereby blowing away the hot air emitted by the milling cutter blank placed in the basket or the hot air emitted upwards from the water tank.

[0004] However, existing cooling devices still have some drawbacks. The cooling water remains stagnant inside the chamber, resulting in insufficient heat exchange between different parts of the tool and the cooling water. This leads to inconsistent cooling rates in different parts of the tool and increases the risk of tool deformation. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model provides a cooling device for the production of metal cutting milling cutters. Its purpose is to solve the problems of insufficient heat exchange between different parts of the tool and the cooling water due to the stasis of cooling water in the tank, resulting in inconsistent cooling rates of different parts of the tool and increasing the risk of tool deformation.

[0006] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: a cooling device for metal cutting milling cutter production, comprising a base, a cooling box installed in the middle of the upper surface of the base, a support frame installed on the top back side of the cooling box, a placement plate installed on the side of the support frame near the cooling box, electric push rods installed in pairs on the top surface of the placement plate, the extended end of the electric push rods connected to a placement frame, a cooling pool installed on one side of the cooling box, a refrigeration box installed on the side of the cooling box away from the cooling pool, a water removal mechanism installed on the support frame, a water supply pipe connected between the bottom side of the cooling box and the cooling pool, and an auxiliary heat dissipation mechanism installed on the lower wall inside the cooling box;

[0007] A refrigeration unit is installed on one side of the refrigeration box. A water pump is connected between the bottom of one side of the refrigeration box and the cooling pool. A switch valve is installed on the water pump. A water pump is installed on the end of the water pump near the refrigeration box. A second water pump is installed on the top of the refrigeration box. A drain pipe is connected between the second water pump and the cooling box.

[0008] Furthermore, the dewatering mechanism includes a mounting frame fixedly installed on a support frame, ventilation cylinders symmetrically installed on the back side of the mounting frame, a fixing plate installed on the inner wall of the ventilation cylinder, a drive motor installed at one end of the fixing plate, and a fan connected to the output end of the drive motor.

[0009] Furthermore, the auxiliary heat dissipation mechanism includes a pair of drive motors two fixedly installed on the bottom surface of the cooling box. The output ends of the four drive motors two extend into the interior of the cooling box and are connected to a rotating shaft. A stirring rack is installed on the rotating shaft.

[0010] Furthermore, each of the two protruding ends of the electric push rods is fixedly mounted with a bracket, and the bracket has a groove that matches the placement frame.

[0011] Furthermore, the placement frame is made of stainless steel.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention relates to a cooling device for metal cutting milling cutter production. It establishes a complete cooling water circulation system by incorporating a refrigeration chamber, a cooling pool, connecting pipes, and two water pumps. The refrigeration unit inside the refrigeration chamber cools the cooling water. The water pumps draw cooling water from the cooling pool into the refrigeration chamber for further cooling. The second water pump then pumps the cooled water back into the cooling chamber through a drain pipe. Simultaneously, used cooling water in the cooling chamber flows back to the cooling pool through a water supply pipe, forming a continuous cycle. This circulating cooling water continuously removes heat from the tool surface, significantly improving heat exchange efficiency compared to stagnant cooling water, allowing the tool to cool down more quickly.

[0014] This invention relates to a cooling device for metal cutting milling cutter production. A second drive motor rotates a shaft, which in turn drives a stirring frame on the shaft to agitate the cooling water within the cooling chamber. The agitation action of the stirring frame ensures a uniform flow of the cooling water within the chamber, preventing localized overheating or underheating. This results in more even heat exchange between different parts of the cutting tool and the cooling water, and a more consistent cooling rate across all parts. This effectively reduces the risk of thermal stress and deformation caused by uneven cooling, thus improving tool quality and yield. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, a cooling device for metal cutting milling cutter production includes a base 1, a cooling box 2 installed in the middle of the upper surface of the base 1, a support frame 3 installed on the top back side of the cooling box 2, a placement plate 11 installed on the side of the support frame 3 near the cooling box 2, electric push rods 4 installed in pairs on the top surface of the placement plate 11, a placement frame 5 connected to the extended end of the electric push rods 4, a cooling pool 6 installed on one side of the cooling box 2, a refrigeration box 7 installed on the side of the cooling box 2 away from the cooling pool 6, a water removal mechanism 8 installed on the support frame 3, a water supply pipe 9 connecting the bottom side of the cooling box 2 to the cooling pool 6, and an auxiliary heat dissipation mechanism 10 installed on the inner lower wall of the cooling box 2.

[0029] A refrigeration unit 701 is installed on one side of the refrigeration box 7. A water pump 702 is connected between the bottom of one side of the refrigeration box 7 and the cooling pool 6. A switch valve 703 is installed on the water pump 702. A water pump 704 is installed on the end of the water pump 702 near the refrigeration box 7. A second water pump 705 is installed on the top of the refrigeration box 7. A drain pipe 706 is connected between the second water pump 705 and the cooling box 2.

[0030] Through the above scheme, the chiller 701 cools the cooling water, the water pump 704 pumps the water from the cooling pool 6 to the cooling box 7 for further cooling, and the water pump 705 then transports the cooled water through the drain pipe 706 to the cooling box 2. Simultaneously, the used water in the cooling box 2 flows back to the cooling pool 6 through the water supply pipe 9. This circulation method keeps the cooling water at a continuously low temperature, quickly removing the heat generated by the metal cutting milling cutter during production, effectively improving production efficiency, shortening the overall production cycle, saving time costs for the enterprise, and enhancing its market competitiveness.

[0031] The dewatering mechanism 8 includes a mounting bracket 801 fixedly installed on the support frame 3. A ventilation duct 802 is symmetrically installed on the back side of the mounting bracket 801. A fixing plate 803 is installed on the inner wall of the ventilation duct 802. A drive motor 804 is installed at one end of the fixing plate 803. A fan 805 is connected to the output end of the drive motor 804.

[0032] Through the above scheme, drive motor 804 drives fan 805 to rotate at high speed, generating a powerful airflow. After the end mill has finished cooling and is removed from cooling chamber 2, it is placed in a suitable location. The airflow generated by fan 805 can quickly dry the moisture on the surface of the end mill, effectively preventing rust caused by moisture residue. Rust not only affects the appearance of the tool, but also reduces its corrosion resistance and service life.

[0033] The auxiliary heat dissipation mechanism 10 includes a pair of drive motors 1001 fixedly installed on the bottom surface of the cooling box 2. The output ends of the four drive motors 1001 extend into the interior of the cooling box 2 and are connected to a rotating shaft 1002. A stirring rack 1003 is installed on the rotating shaft 1002.

[0034] By using the above method, the second drive motor 1001 is started, which drives the rotating shaft 1002 to rotate, thereby causing the stirring rack 1003 to stir the cooling water in the cooling box 2, promoting the flow of cooling water and heat exchange, and improving the cooling effect.

[0035] Both electric push rods 4 have a card holder 401 fixedly installed on the bottom surface of their extended ends. The card holder 401 has a groove 402 that matches the placement frame 5.

[0036] The placement frame 5 is made of stainless steel.

[0037] With the above method, the placement frame 5 is placed in the groove 402 of the card holder 401 to ensure that the placement frame 5 is installed firmly and will not shake or fall off during the extension and retraction of the electric push rod 4. The stainless steel material has good corrosion resistance and strength, and can resist the erosion of cooling water and the surrounding environment, thus extending the service life of the placement frame 5. When placing metal cutting milling cutters, the milling cutters are neatly placed in the placement frame 5, and then the placement frame 5 is placed into or removed from the cooling box 2 by controlling the extension and retraction of the electric push rod 4.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
