Magnetic force polishing machine disc with follow-up heat dissipation blades

Abstract

This invention discloses a magnetic polishing machine disk with follow-up heat dissipation blades, belonging to the technical field of magnetic polishing equipment. The device includes a bakelite disk, magnets, an iron base plate, and follow-up heat dissipation blades. A cold-rolled steel base plate is fixed to the back of the bakelite disk. At least three straight heat dissipation blades are fixed to the back of the iron base plate. These blades have no independent drive source and rotate synchronously with the disk's spindle. This invention breaks with industry-standard design biases, abandoning the traditional independent fan cooling structure. It utilizes the disk's rotational characteristics to achieve follow-up forced air cooling, with heat dissipation start / stop completely synchronized with the polishing process, achieving on-demand adaptive cooling. Simultaneously, the iron base plate serves both structural reinforcement and heat conduction functions, precisely dissipating eddy current heat from the magnets, effectively suppressing high-temperature demagnetization, eliminating the failure rate of external fans, reducing overall energy consumption and cost, and featuring a simple structure and strong adaptability, allowing for direct modification of existing equipment.

Description

Technical Field

[0001] This invention relates to the field of magnetic polishing equipment technology, and specifically to a magnetic polishing machine disk with follow-up heat dissipation blades. Background Technology

[0002] Magnetic polishing equipment relies on a high-speed rotating disk to drive a magnet, generating an alternating magnetic field that drives the magnetic needles to move randomly, thus achieving deburring and mirror polishing of the workpiece. The high-speed cutting of magnetic lines by the magnet continuously generates eddy current heat, which, combined with the heat generated by the motor drive, results in a significant temperature rise inside the equipment cavity.

[0003] Existing technologies suffer from the following common industry problems and technological biases: 1. Inherent industry bias: For a long time, the industry has assumed that hard drives only serve as the magnet carrier and magnetic field generator, without any heat dissipation function. Heat dissipation relies entirely on external independent electric fans, leading to a fixed design mindset. 2. High energy consumption and high failure rate of independent fans: External fans are constantly powered on and in standby mode, resulting in ineffective power consumption. Fan bearings and motors are prone to aging and seizing, directly causing overall heat dissipation failure and rapid demagnetization of the magnets at high temperatures. 3. Mismatch between heat dissipation and operating conditions: Traditional fans provide constant airflow and cannot adaptively adjust to changes in hard drive speed, polishing load, and heat generation. This results in wasted energy under low loads and insufficient heat dissipation under high loads. 4. Lack of heat-conducting and heat-spreading structure: Traditional hard drives lack a metal heat-conducting base plate, causing heat to accumulate on the magnets and preventing rapid heat dissipation. Prolonged high temperatures lead to magnetic performance degradation, accelerated polishing fluid failure, and decreased processing consistency. Summary of the Invention

[0004] The technical problem to be solved by this invention is to address the industry pain points of existing magnetic polishing machines, such as reliance on independent fans for heat dissipation, high failure rate, energy waste, mismatched heat dissipation conditions, and easy demagnetization of magnets. At the same time, it breaks the industry's technical prejudice that disks do not participate in heat dissipation and provides a magnetic polishing machine disk with a self-regulating heat dissipation structure.

[0005] The technical solution of this invention is as follows: A magnetic polishing machine disk with follow-up heat dissipation blades, comprising a bakelite disk, magnets, an iron base plate, and heat dissipation blades. The bakelite disk serves as an insulating load-bearing substrate, with multiple rings of mounting holes on its surface for embedding and fixing the magnets. The iron base plate, made of cold-rolled steel, is locked and fixed to the back of the bakelite disk to achieve overall rigidity enhancement and rapid heat dissipation. Multiple straight heat dissipation blades, with no fewer than two blades, are fixed to the back of the iron base plate. The heat dissipation blades have no independent drive source, no control circuit, and no additional energy consumption; they rely entirely on the synchronous rotation of the disk spindle. Automatic air cooling occurs when the disk is rotating, and cooling stops synchronously when the disk stops, achieving complete linkage between heat dissipation and operating conditions.

[0006] Working Principle: 1. Heat Source Coupling and Conduction: The eddy currents generated by the working magnets transfer heat to the bakelite disk, and then quickly conduct it to the metal base plate, achieving concentrated heat collection; 2. Condition-Driven Air Cooling: The higher the disk speed, the greater the polishing load, and the more intense the magnet heating, the greater the airflow of the rotating blades, automatically matching the heat dissipation requirements and forming an adaptive negative feedback heat dissipation mechanism; 3. Consumption-Free Start-Stop Control: When the equipment stops, there is no heat generation, and the blades stop synchronously, completely eliminating ineffective heat dissipation and idling power consumption; 4. Overall Chamber Cooling: The axial airflow generated by the rotating blades can simultaneously sweep the magnet area, the inside of the chamber, and the motor end, achieving optimized heat dissipation for the entire machine.

[0007] The beneficial effects of this invention are as follows: 1. Breaking industry technical prejudices: Overturning the traditional perception that disks are merely load-bearing components, this invention integrates disk structure and heat dissipation function into a single unit, representing a structural innovation in the industry. 2. Completely eliminating independent fans: Reducing the number of components in the entire machine, lowering costs, and eliminating potential failure points such as fan jamming, burnout, and malfunction, significantly improving heat dissipation reliability. 3. Adaptive and precise heat dissipation: Heat generation is positively correlated with airflow, providing strong heat dissipation under high loads and low heat dissipation under low loads, resulting in optimal energy consumption and maximum heat dissipation efficiency. 4. Effectively suppressing magnet demagnetization: Rapid heat dissipation from the metal base plate and dynamic air cooling from the blades significantly reduce the steady-state operating temperature of the magnets, extending the lifespan of the magnets and polishing fluid. 5. Zero-energy standby: Heat dissipation only occurs during operation; there is no energy consumption when the machine is off, resulting in significant energy savings. 6. High versatility and modifiability: Simple structure and easy disassembly and assembly allow for direct upgrades and replacements for both new and older models. Attached Figure Description

[0012] like Figures 1 to 3 As shown, the present invention includes a bakelite disc 1, magnets 2, an iron base plate 3, and heat dissipation blades 4. The bakelite disc 1 serves as an insulating load-bearing substrate, with multiple layers of mounting holes on its surface. The magnets 2 are embedded and fixed inside the mounting holes and are arranged in concentric circles evenly.

[0013] The back of the bakelite disk 1 is fixed with a steel base plate 3 by locking screws. The steel base plate is made of cold-rolled steel plate, which has excellent structural strength and thermal conductivity. It not only strengthens the overall stability of the disk under high-speed rotation conditions, but also quickly collects and conducts the heat generated by the magnets.

[0014] Several straight heat dissipation fins 4 are fixed to the side of the iron base plate facing away from the bakelite tray. The number of fins is not less than 2, and preferably 4 are evenly arranged. The fins can be fixed by welding, riveting or bolting, which makes assembly flexible and maintenance convenient.

[0015] As a preferred embodiment, the heat dissipation blades can be selected with a plate thickness of 3mm, a blade height of 30mm, and an effective blade length adapted to the disk diameter, approximately one-third of the disk surface diameter. It should be noted that the above dimensions are preferred examples and can be flexibly adjusted according to disk specifications, rotational speed, and power consumption, without limiting the scope of protection of this invention.

[0016] The entire device is assembled on the drive shaft of the polishing machine. During operation, it rotates synchronously at high speed with the shaft. The blades agitate the air in the cavity to form a directional cooling airflow, which continuously blows the iron base plate and the magnet area to achieve forced air cooling. After the machine stops, the blades stop synchronously, and the heat dissipation is automatically shut off.

[0017] Without departing from the inventive concept of this invention, those skilled in the art can make adaptive modifications to the number of blades, fixing method, and blade specifications, all of which fall within the protection scope of this invention.
