Description

Technical Field

[0001] The utility model relates to the technical field of absorbing material processing equipment, in particular to a cutting machine for absorbing materials that can prevent thermal damage. Background Technique

[0002] The so-called absorbing material refers to a kind of material that can absorb or significantly weaken the electromagnetic wave energy projected onto its surface, thereby reducing the interference of electromagnetic waves. In engineering applications, in addition to requiring the absorbing material to have a high absorption rate of electromagnetic waves in a relatively wide frequency band, it is also required to have properties such as light weight, temperature resistance, humidity resistance, and corrosion resistance. Electromagnetic radiation causes direct and indirect harm to the human body through thermal effects, non-thermal effects, and cumulative effects. Research has confirmed that ferrite absorbing materials have the best performance, and they have characteristics such as high absorption frequency bands, high absorption rates, and thin matching thicknesses.

[0003] From the publication number "CN220179448U", its patent name is: A cutting device for processing absorbing materials. The device in this published document cannot cool the guillotine. When the guillotine continuously cuts the absorbing material, the frictional force generated between the guillotine and the absorbing material will cause the temperature of the guillotine itself to gradually rise, resulting in changes in the internal stress of the guillotine, affecting the accuracy of the guillotine in cutting the absorbing material, and further leading to the occurrence of thermal damage to the absorbing material. Based on this, the utility model designs a cutting machine for absorbing materials that can prevent thermal damage to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cutting machine for absorbing materials that can prevent thermal damage to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cutting machine for absorbing materials that can prevent thermal damage, including an operating table and a bracket. The bracket is fixedly arranged at the middle end of the top of the operating table. A driving component is arranged inside the bracket. The driving component includes a sliding frame slidably connected to the top end inside the bracket. An electric push rod is fixedly arranged on the top of the sliding frame, and the top of the electric push rod is fixedly connected to the top end inside the sliding frame. Installation plates are fixedly arranged on the left and right sides of the bottom of the sliding frame. A motor is fixedly arranged on the outer wall of the right installation plate, and the rotating shaft fixedly arranged on the left side of the motor rotates through the installation plate. A cutting blade is fixedly sleeved on the outer part of the rotating shaft. A box body is fixedly arranged on the top of the sliding frame. The box body is made of heat-insulating material. A semiconductor refrigerator is fixedly penetrated through the top of the box body. A pumping and spraying dual-purpose pump is fixedly arranged on the left side of the box body, and a connecting pipe is fixedly arranged on the left side of the pumping and spraying dual-purpose pump.

[0006] Furthermore, the electric push rod has a self-locking function. A positioning hole is integrally arranged at the middle end inside the operating table, and the positioning hole is designed as a through hole.

[0007] Further, a controller is fixedly installed on the outer wall of the bracket, and the controller is connected to the electric push rod, the motor, and the dual-purpose pumping and whipping pump through wires.

[0008] Further, a cavity is integrally formed inside the cutting disc. The cavity is designed to have a circular ring shape, and the center of the circular ring shape of the cavity coincides with the center of the cutting disc.

[0009] Further, one end of the connecting pipe away from the dual-purpose pumping and whipping pump rotatably penetrates through the left end of the rotating shaft. An installation hole is integrally formed inside the rotating shaft, and a connecting head fixedly installed in the middle of the rotating shaft penetrates through the inner side of the cutting disc.

[0010] Further, installation grooves are integrally formed at the front and rear ends inside the installation plate, and a top plate is slidably connected inside the installation grooves.

[0011] Further, the side view cross-section of the top plate is designed to have a U-shaped shape. A spring is fixedly installed on the top of the top plate, and one end of the spring away from the top plate is fixedly connected to the installation plate.

[0012] Further, the resilience of the spring is greater than the gravity of the top plate, and the bottom surface of the top plate is lower than the bottom surface of the cutting disc.

[0015] 2. Through the design of the clamping function, the present utility model can fix the position of the absorbing material before cutting to prevent the tangential force generated during the rotation of the cutting disc from causing the position deviation of the absorbing material.

[0027] The electric push rod 302 has a self-locking function. A positioning hole 4 is integrally arranged in the middle end of the operation table 1.

The controller 5 is connected to the electric push rod 302, the motor 304, and the pumping and sucking dual-purpose pump 309 through wires. A cavity 6 is integrally arranged inside the cutting blade 306. The cavity 6 is designed with a circular ring shape. The center of the circular ring shape of the cavity 6 is concentric with the center of the cutting blade 306. One end of the connecting pipe 310 away from the pumping and sucking dual-purpose pump 309 rotates through the left end of the rotating shaft 305.

Then, the motor 304 and the pulling function of the electric push rod 302 are turned on. The motor 304 drives the rotating shaft 305 to drive the cutting blade 306 to rotate. The electric push rod 302 pulls the carriage 301 to drive the installation plate 303 together with the cutting blade 306 to move along the direction of the absorbing material, so that the cutting blade 306 cuts the absorbing material.

[0030] According to the operation method in Embodiment 1, when the rotating cutting blade 306 moves along the direction of the absorbing material, the top plate 10 first applies a squeezing force to the left and right sides of the area to be cut of the absorbing material. Through the reaction force of the absorbing material, the top plate 10 moves along the direction of the installation groove 9, and then the top plate 10 squeezes the spring 11 to deform. Through the action of the resilience of the spring 11, the top plate 10 applies a soft clamping force to the absorbing material, not only fixing the position of the absorbing material, but also preventing the top plate 10 from causing damage to the absorbing material due to hard clamping, and playing a protective role for the absorbing material.
