Description

Technical Field

[0001] The present invention relates to the technical field of saw blade quenching, and in particular to a saw blade slow quenching system. Background Art

[0002] Saw blades are commonly used cutting tools in industries such as building materials and non-ferrous metals. Heat treatment, especially quenching, is the core process for them to have good comprehensive mechanical properties. The traditional quenching method uses an electric furnace to heat to a certain temperature and then oil or water cooling to make it have higher hardness and wear resistance.

[0003] In the current state of the art, saw blade quenching is primarily performed in a salt bath furnace. One or more saw blades are heated at a time, then placed in a quenching medium to cool. During this rapid cooling and heating process, the saw blades are susceptible to deformation and uneven texture within the material. Furthermore, the surface temperature of the saw blades is high immediately after leaving the quenching furnace, making manual transfer prone to burns and other safety hazards. Furthermore, improper handling during transfer can also cause deformation, impacting the quality of the finished product. Summary of the Invention

DETAILED DESCRIPTION

[0032] like Figure 1 As shown, a saw blade slow quenching system includes a step quenching system 1, a slow cooling system 2, and a blade moving system 3. The step quenching system 1 is arranged at the front end of the entire system, the slow cooling system 2 is arranged in the middle of the system and connected to the discharge port of the step quenching system 1, and the blade moving system 3 is arranged at the rear end of the entire system and connected to the discharge port of the slow cooling system 2.

[0033] The graded quenching system 1 is composed of a plurality of quenching furnaces. A feed port 107 is provided at the front end of the graded quenching system 1 and a discharge port is provided at the rear end of the graded quenching system 1 and is connected to the slow cooling system 2.

[0034] The slow cooling system 2 includes a roller frame 201, on which a transmission roller 202 is installed and connected to the discharge port of the graded quenching system 1. The lower slow cooling platform 203 is arranged parallel to the roller frame 201. Columns 204 are vertically arranged at the four corners of the lower slow cooling platform 203. The upper end faces of the columns 204 are connected to the top plate. The four corners of the lifting plate 205 are sleeved on the columns 204 and slide vertically up and down along the columns 204. The lower end face of the lifting plate 205 is correspondingly provided with an upper slow cooling platform 2015. The upper end face of the lifting plate 205 is connected to the hydraulic system. The lower slow cooling platform 203 is connected to the liquid cooling system, and the upper slow cooling platform 2015 is connected to the air cooling system.

[0035] The paddle system includes a horizontal paddle device and a vertical paddle moving device. The horizontal paddle device is installed on the paddle bracket 301. The paddle bracket 301 is set at the discharge end of the slow cooling system 2 and is arranged parallel to the slow cooling system 2. A bridge frame 308 is set above the paddle bracket 301, and a vertical paddle moving device is installed on the bridge frame 308.

[0036] The preferred solution is Figure 2 As shown, the graded quenching system 1 is assembled by four quenching furnaces, namely a first-stage quenching furnace 101, a second-stage quenching furnace 102, a third-stage quenching furnace 103 and a fourth-stage quenching furnace 104. The four quenching furnaces are interconnected and their internal temperatures decrease in sequence. Heating electrodes 105 are provided on both sides of the quenching furnace for heating in the furnace. A feed port 107 is provided on the first-stage quenching furnace 101, and a feed roller 106 is mounted on the outer side of the feed port 107. During operation, the saw blade is input into the first-stage quenching furnace 101 from the feed port 107 by the feed roller 106, and is gradedly heated by the first-stage quenching furnace 101, the second-stage quenching furnace 102, the third-stage quenching furnace 103 and the fourth-stage quenching furnace 104, and is finally output from the tail end of the fourth-stage quenching furnace 104. The quenching furnace uses a heating method with decreasing temperature, which can achieve slow heating of the saw blade, prevent rapid cooling and heating from causing impact on the saw blade and producing adverse tissue.

[0037] The preferred solution is Figure 3 and Figure 4 As shown, the hydraulic system includes a hydraulic press 206 and a hydraulic rod 207. The hydraulic press 206 is vertically installed on the top plate of the column 204. The hydraulic press 206 is connected to the lifting plate 205 through the hydraulic rod 207 and drives the lifting plate 205 to slide vertically up and down along the column 204. The liquid cooling system includes a liquid supply box 208 and a liquid supply pipe 209. The liquid supply box 208 is arranged on both sides of the lower slow cooling platform 203. The inner side of the liquid supply box 208 is connected to the lower slow cooling platform 203, and the outer side of the liquid supply box 208 is connected to the liquid supply pipe 209.

[0038] When the steel saw blade is clamped and fixed by the lower slow cooling table 203 and the upper slow cooling table 2015, the coolant flows into the liquid supply box 208 through the liquid supply pipe 209, and is then injected into the lower slow cooling table 203 by the liquid supply box 208. Finally, after heat exchange, it flows out from the liquid supply box 208 and the liquid supply pipe 209 to form a circulation. By controlling the temperature of the coolant, the temperature of the lower slow cooling table 203 can be controlled, thereby achieving the effect of slow cooling of the saw blade, making the cooling process of the saw blade more stable, and further improving the quenching quality of the saw blade.

[0039] The preferred solution is Figure 3 and Figure 4As shown, the air cooling system includes a blower 2010 and an exhaust fan 2013, which are respectively installed on both sides of the top plate and connected to the upper air supply box 2011. The upper air supply box 2011 is connected to the lower air supply box 2014 through a spiral air supply pipe 2012. The lower air supply box 2014 is installed on both sides of the upper slow cooling stage 2015 and is connected to the upper slow cooling stage 2015.

[0040] After the steel saw blade is clamped and fixed by the lower slow cooling table 203 and the upper slow cooling table 2015, the steel saw blade is slowly cooled between the two. When the tail end needs to be cooled faster, the blower 2010 and the exhaust fan 2013 are turned on, and the cooling air is injected into the upper air supply box 2011 through the blower 2010, and then injected into the lower air supply box 2014 through the upper air supply box 2011, and the lower air supply box 2014 is injected into the upper slow cooling table 2015 for rapid cooling. Finally, the cooling air flows back to the upper air supply box 2011 from the lower air supply box 2014 on the other side, and is finally extracted through the exhaust fan 2013 to complete the cold air cycle.

[0041] The preferred solution is Figure 5 As shown, the horizontal paddle device includes a sliding base 302, which is installed on the inner side of the paddle bracket 301 and slides along the paddle bracket 301. A first tooth plate 303 is installed on the outer side of the paddle bracket 301. A first rotary motor 304 is provided at the end of the sliding base 302. The transmission wheel of the first rotary motor 304 is engaged with the first tooth plate 303. The rotation of the first rotary motor 304 drives the sliding base 302 to slide along the first tooth plate 303. A horizontal cylinder 305 is installed on the inner side of the sliding base 302. The horizontal cylinder 305 is connected to the paddle plate 307 via a horizontal gas rod 306. The horizontal gas rod 306 extends and retracts to drive the paddle plate 307 to flip the paddle.

[0042] When the saw blade is completely cooled on the lower slow cooling table 203, the first rotary motor 304 starts first and drives the transmission gear to rotate. The transmission gear is meshed with the first tooth plate 303 and drives the sliding base 302 to move forward along the first tooth plate 303. The first tooth plate 303 drives the paddle plate 307 to slide forward synchronously. When the paddle plate 307 moves to above the saw blade, the first rotary motor 304 stops working and the horizontal cylinder 305 starts. The horizontal cylinder 305 drives the horizontal gas rod 306 to extend. After the horizontal gas rod 306 extends, it pushes the paddle plate 307 to flip downward and hook the saw blade. Finally, the horizontal cylinder 305 drives the horizontal gas rod 306 to contract and finally drives the paddle plate 307 to move back until the saw blade is completely pulled out and transmitted to the paddle bracket 301.

[0043] The preferred solution is Figure 6As shown, the vertical sheet moving device includes a sliding base plate 3010 and a second tooth plate 3011, the second tooth plate 3011 is arranged parallel to the side of the bridge frame 308, the sliding base plate 3010 is arranged on the second tooth plate 3011 and can slide along the tooth plate, a second rotary motor 309 is arranged on the sliding base plate 3010, a transmission wheel of the second rotary motor 309 is engaged with the second tooth plate 3011, and the second rotary motor 309 rotates to drive the sliding base plate 3010 to slide along the second tooth plate 3011; a second cylinder 3012 is vertically arranged on the front face of the sliding base plate 3010, the gas rod of the second cylinder 3012 is vertically connected to the mounting plate 3013, and the lower end face of the mounting plate 3013 is provided with a suction cup 3014;

[0044] After the sliding base plate 3010 is in place, the second cylinder 3012 pushes the gas rod to extend and drives the mounting plate 3013 to move vertically downward. The suction cup 3014 on the lower end surface of the mounting plate 3013 slides downward synchronously and finally absorbs the saw blade. Then the second cylinder 3012 controls the gas rod to contract and drives the mounting plate 3013 to move vertically upward until it is restored. After the mounting plate 3013 is restored, the second rotating motor 309 continues to start and drives the sliding base plate 3010 to continue to slide to the right until the saw blade is transported to the next delivery point. When the saw blade completes the transmission, each component will move in the opposite direction until all return to the initial state and prepare for the transmission of the next saw blade.
