Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a magnetic material cutting heat dissipation device. Background Art

[0002] The most commonly used processing method for magnetic materials is cutting. Cutting is usually performed using laser cutting or a cutting knife. The cutting knife will generate a high temperature during the processing due to the characteristics of the magnetic material itself. The increase in temperature will affect the service life of the cutting knife.

[0003] Most of the existing heat dissipation methods use coolant or a hair dryer aimed at the cutting knife. However, in actual use, the coolant will inevitably spill on the surface of the magnetic material when flushing the cutting knife. The magnetic material after processing needs to be cleaned before the next processing, which increases the operation steps and reduces the processing efficiency. The method of using a hair dryer directly at the cutting knife can only blow on the part of the cutting knife exposed to the outside. Usually, a protective shell is set on the outside of the cutting knife, and only a small part of the cutting knife is exposed to the outside. The hair dryer blows on the cutting knife for a short time, and the cooling and heat dissipation effect is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0007] The utility model provides a magnetic material cutting and heat dissipation device.

[0008] Furthermore, the driving gear has a diameter greater than that of the driven gear.

[0009] Furthermore, both ends of the positioning rod are connected to the protective shell and the power device through plane bearings respectively.

During the rotation process, the driving gear drives the driven gear meshing with it to rotate accordingly. During the rotation process, the positioning rod inserted inside the driven gear and the fan blade arranged on the outside of the positioning rod rotate simultaneously. Since the diameter of the driving gear is larger than that of the driven gear, the rotation speed of the driven gear is greater than that of the driving gear. During the rotation process, the fan blade generates wind blowing in the direction of the protective shell and enters the inside of the protective shell along the groove to contact the cutting knife, so as to take away the high temperature in the cutting knife to achieve the effect of heat dissipation. No additional operation is required by the operator during the whole process, and the area of ​​the cutting knife contacting the wind is increased, thereby improving the cooling and heat dissipation effect.

[0025] Working principle description: First, the power device 4 is started to rotate, and the cutting knife 5 is driven to rotate inside the protective shell 6 to perform cutting processing. When the cutting knife 5 rotates, the driving gear 8 set at the output end of the power device 4 follows the rotation. During the rotation process, the driving gear 8 drives the driven gear 9 meshing with it to follow the rotation. During the rotation process, the positioning rod 10 inserted inside the driven gear 9 and the fan blade 11 set on the outside of the positioning rod 10 rotate at the same time.
