Description

Technical Field

[0001] This invention relates to the field of sawing equipment technology, and more specifically, to a saw blade angle adjustment device for a metal and wood cutting machine. Background Technology

[0002] A cutting machine is an industrial device that uses a high-speed rotating circular saw blade to cut metal or wood materials. Its basic working principle is to drive the transmission system through a motor to make the saw blade rotate at high speed. The saw blade teeth contact the material, and the material is cut through continuous rotation and cyclic cutting.

[0003] When the saw blade angle adjustment device of the cutting machine is working, after adjusting the cutting angle of the metal or wood material, in order to avoid shaking during the subsequent cutting process, the material needs to be firmly positioned and fixed by the clamping and positioning mechanism in the device.

[0004] However, when the aforementioned existing saw blade angle adjustment device is used to cut metal materials after the angle has been adjusted and fixed, the large amount of frictional heat generated during the cutting process can easily cause thermal expansion of the metal material at the cutting part. Furthermore, when the elongation of the metal material in the length direction is hindered by both the clamping and positioning mechanism in the angle adjustment device and the circular saw blade of the cutting machine, the metal material will inevitably bend and deform under stress. This abnormal stress state will cause the flatness of the cut part of the metal material to deteriorate sharply, resulting in bending or warping, which cannot meet the requirements for precise fit of the cut metal material.

[0005] In view of this, we propose a saw blade angle adjustment device for metal and wood cutting machines. Summary of the Invention

The outlet of the flat-nozzle high-pressure nozzle is located above the front side of the heat-inducing plate.

[0018] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. The operator adjusts the metal material to be cut to the cutting angle using an angle adjuster and fixes the adjusted angle. When cutting the metal material, the pumping component in the clamping and positioning component continuously pumps coolant into the cooling channel in the heating plate. The coolant is then sprayed onto the cutting surface of the metal material by the flat-nozzle high-pressure nozzle of the high-pressure spray component. The material is passively cooled by the cooling channel in the heating plate that is in contact with the cutting part of the metal material, and then the cutting surface of the metal material is precisely cooled by the high-pressure spray component. This achieves dual cooling treatment for the cutting material, which can effectively reduce the probability of thermal expansion of the cutting part during the metal material cutting process, thus reducing the probability of bending or warping. This improves the quality of the angle cutting of the metal material and helps to improve the precision fit of the material.

[0019] 2. Due to the high temperature of the cut surface, when the high-pressure jet assembly performs precise active high-pressure jet cooling on the cut surface of the metal material, the sprayed high-pressure coolant directly impacts the cut surface and can directly penetrate the cutting gap, precisely delivering the coolant to the core and high-temperature area of ​​the cut surface. Compared to the traditional method of spraying coolant, where the coolant only contacts the surface of the cut area, the active high-pressure jet cooling adopted in this invention not only achieves cooling and temperature reduction of the cut surface but also precisely contacts the high-temperature area of ​​the cut surface, forming strong convective heat transfer. This results in a more efficient and in-depth cooling treatment of the cut metal material, improving the cooling effect on the cut metal material.

[0020] 3. During the material cutting process, the material is pressed and fixed by the pressure device on the heating plate. The pressure device located at the front end of the heating plate not only fixes the material but also senses the heat energy accumulated at the cutting part. Because it is close to the cutting part, the frictional heat generated during the material cutting process is continuously transferred to the pressure device at the front end of the heating plate. When the temperature at the pressure device at the front end of the heating plate exceeds its preset temperature value, the thermal expansion layer expands due to heat. This drives the first resistor spring in the synchronous control module to move through the plug rod structure, reducing the resistance between the first resistor spring and the output end of the first resistor body. This allows for a synchronous increase in the power of the water pump, which in turn increases the flow rate of the coolant in the cooling channel and the injection pressure of the high-pressure injection component. This enhances the cooling effect on the surface of the cutting part while allowing more coolant to enter the core and high-temperature area of ​​the cutting surface, significantly improving the actual cooling speed of the cutting surface.

[0021] 4. When the thermal expansion layer expands due to heat, it drives the first resistor spring in the synchronous control module to move through the plug rod structure. Simultaneously, it also drives the second resistor spring to move, increasing the resistance between the second resistor spring and the output terminal of the second resistor body. This reduces the output power of the linear module. Furthermore, when the temperature at the cutting part is high and exceeds the preset temperature value in the pressure reducer, and the coolant flow rate in the cooling channel and the injection pressure of the high-pressure injection component are further increased, the feed speed of the metal material is simultaneously reduced. This reduces the cutting load and prevents the temperature at the cutting part from rising uncontrollably. At the same time, with the increased injection pressure, more coolant can enter the core and high-temperature area of ​​the cutting surface per unit time. This effectively avoids thermal expansion of the cutting part due to overheating during the metal material cutting process, which could lead to bending or warping. This ensures the cutting accuracy of the metal material at different cutting angles and meets the requirements for precise fit of the cut metal material. Attached Figure Description

[0047] Reference Figure 1 , Figure 2 , Figures 6 to 12The present invention provides a saw blade angle adjustment device for a metal and wood cutting machine. The synchronous control module also includes an outer cylinder cover 212 connected to the top of the hollow positioning rod 214 in the corresponding presser. The outer cylinder cover 212 is made of insulating material. Both the first resistor 232 and the second resistor 233 are connected to the inner wall of the outer cylinder cover 212.

[0048] Reference Figures 6 to 8 The present invention provides a saw blade angle adjustment device for a metal and wood cutting machine. The cooling channel includes an inlet, an outlet, and an inner liquid cooling channel 222 disposed inside the heat-conducting plate 202. The inner liquid cooling channel 222 is S-shaped. Both the input port and the output port are connected to the heat-drawing plate 202, and the input port is connected to the input end of the internal liquid cooling channel 222, and the output port is connected to the output end of the internal liquid cooling channel 222. The high-pressure injection assembly includes a universal bamboo tube 210 with one end connected to the output port in the cooling channel, and a flat-nozzle high-pressure nozzle 211 connected to the other end of the universal bamboo tube 210. The output port of the flat-nozzle high-pressure nozzle 211 is located above the front side of the heat-inducing plate 202.

[0049] When cutting metal materials, coolant is continuously pumped into the cooling channels of the heating plate 202 by the pumping component in the clamping and positioning component. The coolant is then sprayed onto the cutting surface of the metal material by the flat high-pressure nozzle 211 of the high-pressure spray component. The material cutting area is passively cooled by the cooling channels in the heating plate 202 that are in contact with the cutting area of ​​the metal material, and then the cutting surface of the metal material is precisely cooled by the high-pressure spray component. This achieves dual cooling treatment for the cutting material, which can effectively reduce the probability of thermal expansion of the cutting area during the metal material cutting process, thus reducing the probability of bending or warping. This improves the quality of the angled cutting of the metal material and helps to improve the precision fit of the material.

[0050] Because the cutting surface temperature is high, when the metal material is cut using a high-pressure jet assembly for precise active high-pressure jet cooling, the sprayed high-pressure coolant directly impacts the cutting surface and penetrates directly into the cutting kerf, precisely delivering the coolant to the core and high-temperature areas of the cutting surface. Compared to traditional coolant spraying methods, where the coolant only contacts the surface of the cutting area, the active high-pressure jet cooling method employed in this invention not only cools the surface of the cutting area but also precisely contacts the high-temperature areas of the cutting surface, creating strong convective heat transfer. This results in more efficient and deeper cooling of the metal material cutting area, improving the cooling effect.

[0051] Reference Figure 1 , Figure 2 , Figure 4 , Figures 6 to 8 The present invention provides a saw blade angle adjustment device for a metal and wood cutting machine, wherein the pumping component includes a water collection tank 205 disposed below the saw kerf on the cutting table 101; A filter screen is connected inside the water collection tank 205. An observation window is also provided on the side wall of the water collection tank 205. The observation window is made of transparent material and allows the operator to easily observe the coolant level inside the water collection tank 205, so that the operator can add coolant to the water collection tank 205 in a timely manner. The coolant is recycled through a collection tank 205 located below the saw cut. Before collecting the coolant, the collection tank 205 filters out the cutting debris in the coolant through a filter screen. The filtered coolant is then collected by the collection tank 205, thus achieving the recycling of the coolant.

[0052] A water pump 206 is connected to the side wall of the water collection tank 205. The input end of the water pump 206 passes through the side wall of the water collection tank 205 and extends into the inner cavity of the water collection tank 205. The output end of the water pump 206 extends into the inner cavity of the water collection tank 205 and is located below the filter screen. A water guide hose is connected to the output end of the water pump 206, and the end of the water guide hose away from the water collection tank 205 is connected to the inlet of the cooling channel. The second resistor spring 231 and the second resistor body 233 are both electrically connected to the water pump 206 in the pumping assembly. Both the first resistor spring 230 and the first resistor body 232 are electrically connected to the linear module 201.

[0053] During the material cutting process, the material is pressed and fixed by the pressure device on the heating plate 202. The pressure device located at the front end of the heating plate 202 not only fixes the material but also senses the heat energy accumulated at the cutting part. Because it is close to the cutting part, the frictional heat generated during the material cutting process is continuously transferred to the pressure device at the front end of the heating plate 202. When the temperature at the pressure device at the front end of the heating plate 202 exceeds its preset temperature value, the thermal expansion layer 226 expands due to heat. This drives the first resistor spring 230 in the synchronous control module to move through the plug rod structure. This reduces the resistance between the first resistor spring 230 and the output end of the first resistor body 232, thereby synchronously increasing the power of the water pump 206. This further increases the flow rate of the coolant in the cooling channel and the injection pressure of the high-pressure injection component. This not only enhances the cooling effect on the surface of the cutting part but also allows more coolant to enter the core and high-temperature area of ​​the cutting surface, which greatly improves the actual cooling speed of the cutting surface.

[0054] When the thermal expansion layer 226 expands due to heat, it drives the first resistor spring 230 in the synchronous control module to move through the plug rod structure. Simultaneously, it also drives the second resistor spring 231 to move, increasing the resistance between the second resistor spring 231 and the output terminal of the second resistor body 233. This reduces the output power of the linear module 201. Furthermore, when the temperature at the cutting part is high and exceeds the preset temperature value in the pressure reducer, and the coolant flow rate in the cooling channel and the injection pressure of the high-pressure injection component are further increased, the feed speed of the metal material is simultaneously further reduced. This reduces the cutting load and prevents the temperature at the cutting part from rising uncontrollably. At the same time, with the injection pressure increased, more coolant can enter the core and high-temperature area of ​​the cutting surface per unit time. This effectively avoids thermal expansion of the cutting part due to overheating during the metal material cutting process, which could lead to bending or warping. This ensures the cutting accuracy of the metal material at different cutting angles and meets the requirements for precise fit of the cut metal material.
