Description

Technical Field

[0001] This utility model relates to the technical field of blade cooling devices, specifically a blade cooling device for a cutting machine. Background Technology

[0002] Cutting machines are indispensable and efficient equipment in modern industrial production, widely used for the precise cutting of materials such as paper, plastics, and metals. As the core component of a cutting machine, the material and design of the blade directly affect the cutting accuracy and efficiency. High-quality blades are usually made of high-hardness alloy steel, and undergo fine grinding and heat treatment to ensure sharpness and durability, easily meeting the demands of high-intensity operations. However, with the increase in cutting frequency, the heat generated by the blade during high-speed operation may affect its performance, or even cause material deformation or blade damage. To address this, modern cutting machines are equipped with intelligent cooling devices that effectively reduce blade temperature and extend service life through circulating coolant or forced air cooling technology, while ensuring the stability of cutting quality.

[0003] The application of blade cooling devices enables cutting machines to maintain high efficiency and precision even under high-load operations, but it still has certain problems: 1) low cooling efficiency, serious waste of coolant, and environmental pollution and health risks; 2) poor cooling uniformity and poor cooling effect in high-temperature cutting areas. Therefore, in view of the above situation, it is urgent to develop a blade cooling device for cutting machines to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a blade cooling device for a cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a blade cooling device for a cutting machine, comprising a cutting blade assembly and a cooling mechanism, wherein the two cooling mechanisms are horizontally distributed opposite each other, and the cutting blade assembly is movably disposed between the two cooling mechanisms;

[0006] The cutting blade assembly includes a cutting blade, a blade holder, and an inner cooling plate. The two cutting blades have grooves on adjacent sides, and the two inner cooling plates are respectively embedded in the grooves. The cutting blades can be detachably installed on the blade holder.

[0007] The cooling mechanism includes two sets of cooling components distributed opposite to each other. The cooling components are composed of an outer cooling plate a and an outer cooling plate b. Both the outer cooling plate a and the outer cooling plate b have matching internal flow channels. One side of the outer cooling plate b has an interface b that communicates with the internal flow channel.

[0008] Preferably, the cooling mechanism includes a sliding shaft, an arc-shaped sliding support structure, a return spring, a fixed shaft, a connecting member, and an arc-shaped connecting rod. The top end of the arc-shaped sliding support structure is slidably mounted on the sliding shaft, the cooling component is vertically mounted on the bottom end of the arc-shaped sliding support structure, the return spring is sleeved on one end of the sliding shaft adjacent to the cooling component, the fixed shaft is horizontally arranged on one side of the cooling component, and one end of the connecting member is rotatably mounted on the fixed shaft. The two connecting members of the two cooling mechanisms are hinged together by the arc-shaped connecting rod. Specifically, the arc-shaped sliding support structure can drive the cooling component to reciprocate along the axial direction of the sliding shaft.

[0009] Preferably, a drive shaft is fixed on one side of the cutter holder. Specifically, the cutter holder is installed on the lifting structure of the cutting machine. The drive shaft is perpendicularly aligned with and compatible with the arc-shaped connecting rod. When the cutting machine drives the cutter holder to rise, the drive shaft, in conjunction with the arc-shaped connecting rod and the connecting piece, drives the cooling components to move axially along the sliding shaft. The cooling components on both sides move towards the cutting blade in the middle position until the outer cooling plate b of the cooling components is in close contact with the outer wall of the cutting blade, thereby achieving the cooling effect on the cutting blade.

[0010] Preferably, the inner cooling plate has a cooling channel inside, and one side of the inner cooling plate has an interface a communicating with the cooling channel. Specifically, the inner cooling plate, in conjunction with the internal cooling channel, can continuously dissipate heat from the cutting blade, thereby improving the cooling effect of the cutting blade.

[0011] Preferably, the outer side of the outer cooling plate b is adapted to the outer surface of the cutting blade. Specifically, when the outer cooling plate b is in contact with the cutting blade, it can dissipate heat from the outside of the cutting blade.

[0012] Compared with the prior art, the present invention provides a blade cooling device for a cutting machine, which has the following beneficial effects:

[0013] Its cutting blade has an embedded cooling plate for continuous internal heat dissipation, combined with an external cooling component for intermittent heat dissipation from the outer wall of the cutting blade. Both cooling structures adopt a liquid cooling design, which can achieve a combination of internal and external cooling. This combined internal and external cooling method can dissipate heat from the blade more comprehensively, so that the heat generated by the blade during the cutting process can be removed more quickly. Compared with the traditional single cooling method, the cooling efficiency is greatly improved. Both the internal and external cooling plates adopt an internal flow channel design. When the coolant flows in the internal flow channel, the contact area with the blade is larger, the heat exchange effect is better, and the blade temperature can be reduced more effectively, ensuring the performance and stability of the blade in high-temperature working environments.

[0026] The cutting blade assembly 10 includes a cutting blade 110, a blade holder 120, and an inner cooling plate 140. The two cutting blades 110 have grooves on adjacent sides, and the two inner cooling plates 140 are respectively embedded in the grooves. The cutting blades 110 can be detachably mounted on the blade holder 120.

[0027] The cooling mechanism 20 includes two sets of cooling components 240 distributed opposite to each other. The cooling components 240 are composed of an outer cooling plate a241 and an outer cooling plate b242. The outer cooling plate a241 and the outer cooling plate b242 are both provided with matching inner flow channels 243. An interface b244 communicating with the inner flow channel 243 is provided on one side of the outer cooling plate b242.

[0028] Preferably, the cooling mechanism 20 includes a sliding shaft 210, an arc-shaped sliding support structure 220, a return spring 230, a fixed shaft 250, a connecting member 260, and an arc-shaped connecting rod 270. The top end of the arc-shaped sliding support structure 220 is slidably mounted on the sliding shaft 210. The cooling component 240 is vertically mounted on the bottom end of the arc-shaped sliding support structure 220. The return spring 230 is sleeved on one end of the sliding shaft 210 adjacent to the cooling component 240. The fixed shaft 250 is horizontally arranged on one side of the cooling component 240. One end of the connecting member 260 is rotatably mounted on the fixed shaft 250. The two connecting members 260 of the two sets of cooling mechanisms 20 are hinged together by the arc-shaped connecting rod 270. Specifically, the arc-shaped sliding support structure 220 can drive the cooling component 240 to reciprocate along the axial direction of the sliding shaft 210.

[0029] Preferably, a drive shaft 121 is fixedly provided on one side of the cutter holder 120. Specifically, the cutter holder 120 is installed on the lifting structure of the cutting machine. The drive shaft 121 is vertically aligned and compatible with the arc-shaped connecting rod 270. When the cutting machine drives the cutter holder 120 to rise, the drive shaft 121, in conjunction with the arc-shaped connecting rod 270 and the connecting piece 260, drives the cooling assembly 240 to move axially along the sliding shaft 210. The cooling assemblies 240 on both sides move towards the cutting blade 110 in the middle position until the outer cooling plate b242 of the cooling assembly 240 is in close contact with the outer wall of the cutting blade 110, thereby achieving the cooling effect on the cutting blade 110.

[0030] Preferably, the inner cooling plate 140 has a cooling channel 141 inside, and an interface a130 communicating with the cooling channel 141 is provided on one side of the inner cooling plate 140. Specifically, the inner cooling plate 140, in conjunction with the internal cooling channel 141, can continuously dissipate heat from the cutting blade 110, thereby improving the cooling effect of the cutting blade 110.

[0031] Preferably, the outer side of the outer cooling plate b242 is adapted to the outer surface of the cutting blade 110. Specifically, when the outer cooling plate b242 is in contact with the cutting blade 110, it can dissipate heat from the outside of the cutting blade 110.

[0032] Working principle: When the cutting machine is working, it drives the cutting blade assembly 10 to descend and achieve the aluminum material cutting effect. During this process, the cooling circulation equipment is connected to the interface a130. The coolant enters the internal cooling channel 141 through the interface a130 to achieve a continuous heat dissipation effect. After the cutting is completed, the cutting machine drives the cutting blade assembly 10 to rise. When rising, it cooperates with the drive shaft 121 on one side, the arc-shaped connecting rod 270 and the connecting piece 260 to drive the cooling assembly 240 to move axially towards the middle position along the sliding shaft 210. When the cutting blade assembly 10 moves to the highest position, the outer cooling plates b242 of the two sets of cooling assemblies 240 are in close contact with the outer wall of the cutting blade 110. The cooling circulation equipment is connected to the interface b244. The coolant enters the internal inner channel 243 through the interface b244 and works with the outer cooling plates a241 and b242 to dissipate heat from the cutting blade 110.
