Description
Technical Field
[0001] This utility model relates to the technical field of tempering saw blades, and in particular to a bell-shaped high-efficiency tempering device for tempering saw blades. Background Technology
[0002] The structure of the saw blades produced in a certain workshop is as follows: Figures 1-2 As shown, a central hole 1 is provided in the center of the saw blade, and multiple tooth seats 2 are evenly fixed on the outer edge of the saw blade. The top and bottom surfaces of the tooth seats 2 are flush with the top and bottom surfaces of the saw blade, respectively, and the inner end face of the tooth seats 2 is used for welding with the alloy cutter head.
[0003] When several such products are produced in the workshop Figures 1-2 After processing the saw blades shown, the process requires tempering these saw blades to improve their mechanical strength. The principle of tempering is as follows: first, heat the saw blade to 350~400℃, hold it at that temperature for a period of time, and then air cool the saw blade to complete the tempering process.
[0004] The workshop uses, for example Figure 3 The tempering furnace shown is used to temper the saw blade. The tempering furnace includes a furnace body 3 and a vertical hydraulic cylinder 4 fixed to the top of the furnace body 3. An opening communicating with the inner cavity of the furnace body 3 is opened at the right end. Multiple stepped columns 5 are fixed on the bottom surface of the inner cavity of the furnace body 3. A heater 6 and a temperature sensor A7 are fixed on the top surface of the inner cavity of the furnace body 3. The wire of the heater 6 passes through the top wall of the furnace body 3 and is connected to the power supply. The signal line of the temperature sensor A7 passes through the side wall of the furnace body 3 and is connected to the controller. An insulating door 8 is fixed at the bottom of the piston rod of the vertical hydraulic cylinder 4. The insulating door 8 is in contact with the right end face of the furnace body 3.
[0005] The method by which workers use this tempering furnace to temper the produced saw blades is as follows: S1. Temper the first batch of saw blades: S11. The worker takes out a certain number of saw blades and inserts them into the inner cavity of the furnace body 3 through the opening. Then, the worker places the center hole 1 of the saw blade onto the stepped column 5, thereby stacking multiple saw blades on the stepped column 5, thus realizing the installation of the first batch of saw blades 25 inside the furnace body 3. Figure 4 As shown; S12. The worker controls the piston rod of the vertical cylinder 4 to extend downwards. The piston rod drives the insulating door 8 to move downwards. When the piston rod of the vertical cylinder 4 is fully extended, the insulating door 8 closes the opening of the furnace body 3. Figure 5 As shown; S13. The worker turns on the power supply, which powers the heater 6 through the wires. The heater 6 emits heat to gradually raise the temperature inside the furnace body 3, thereby gradually heating the first batch of saw blades 25. At the same time, the temperature sensor A7 monitors the temperature inside the furnace body 3 in real time and transmits the temperature to the controller through the signal line. When the temperature sensor A7 detects that the temperature inside the furnace body 3 reaches 350~400℃, the worker turns off the power supply, and the heater 6 stops heating the first batch of saw blades 25. S14. After a period of heat preservation, the worker controls the piston rod of the vertical cylinder 4 to retract upwards. The piston rod drives the insulation door 8 to move upwards. At this time, the insulation door 8 no longer seals the opening of the furnace body 3. Simultaneously, the heat from the first batch of saw blades 25 dissipates from the opening of the furnace body 3, in the following direction: Figure 6 As shown by the middle arrow, the first batch of saw blades 25 are gradually air-cooled; when the temperature sensor A7 detects that the temperature inside the furnace body 3 has reached room temperature, the first batch of saw blades are air-cooled to room temperature, and thus the first batch of saw blades are finally tempered. S2. The workers remove the first batch of tempered saw blades from the opening in the furnace body 3. S3. The worker repeats steps S2 to S3 once to temper the second batch of saw blades.
[0006] However, although the tempering furnace used in the workshop can temper the first and second batches of saw blades, it still reveals the following technical defects in actual use: I. In step S14, it is necessary to wait for the first batch of saw blades 25 in the furnace body 3 to be air-cooled to room temperature before the second batch of saw blades can be heated and then tempered. This undoubtedly prolongs the tempering time of the second batch of saw blades and thus reduces the tempering efficiency of the saw blades.
[0007] II. In step S14, the heat on the first batch of saw blades 25 can only be dissipated from the opening of the furnace body 3, which causes uneven heat dissipation, thereby reducing the tempering quality of the saw blades. In addition, it requires a long time to air-cool the first batch of saw blades 25 to room temperature, which undoubtedly further prolongs the tempering time of the second batch of saw blades, thereby further reducing the tempering efficiency of the saw blades.
[0008] Therefore, there is an urgent need for a tempering device that can make the saw blade dissipate heat evenly and greatly improve the tempering efficiency of the saw blade. Utility Model Content
[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bell-shaped high-efficiency tempering device for saw blade tempering that enables uniform heat dissipation and greatly improves the tempering efficiency of saw blades.
[0010] The purpose of this utility model is achieved through the following technical solution: a bell-shaped high-efficiency tempering device for tempering saw blades, which includes a gantry frame fixed on a base plate and a lifting cylinder fixed on the top wall of the gantry frame.

A heat-conducting inner bell is fixed inside the heat-insulating outer bell and on its bottom wall. Multiple turns of heating coils are wound around the outer wall of the heat-conducting inner bell. The wiring of the heating coils passes upward through the top wall of the heat-insulating outer bell and is connected to a power source. The pad is provided with a first turnover assembly for installing and rotating the first batch of saw blades. The first turnover assembly is located on the left side of the gantry frame. The first turnover assembly includes a first feed cylinder fixed on the pad. A first heat insulation seat is fixed on the working end of the piston rod of the first feed cylinder. A first car body is fixed at the bottom of the first heat insulation seat and supported on the top surface of the pad. A stepped column is fixed on the top surface of the first heat insulation seat.

A second car body is fixed at the bottom of the second heat insulation seat and supported on the top surface of the pad.

[0011] A temperature sensor B is fixed on the top wall of the inner cavity of the heat-conducting inner bell jar. The signal line of the temperature sensor B passes through the top wall of the heat-conducting inner bell jar and the top wall of the heat-insulating outer bell jar in sequence and is connected to the controller.
[0012] Rollers supporting the top surface of the pad are provided on the bottom surface of both the first and second vehicle bodies.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 7-10 As shown, a bell-shaped high-efficiency tempering device for tempering saw blades includes a gantry frame 10 fixed on a base plate 9 and a lifting cylinder 11 fixed on the top wall of the gantry frame 10. The piston rod of the lifting cylinder 11 extends downward through the top wall of the gantry frame 10, and a heat-insulating outer bell 12 is fixed on its extended end. A heat-conducting inner bell 13 is fixed inside the heat-insulating outer bell 12 and on its bottom wall. Multiple turns of heating coils 14 are wound around the outer wall of the heat-conducting inner bell 13. The wiring of the heating coils 14 extends upward through the top wall of the heat-insulating outer bell 12 and is connected to a power source. The bottom surface of the heat-insulating outer bell 12 is flush with the bottom surface of the heat-conducting inner bell 13.
[0018] The pad 9 is provided with a first turnover assembly 16 for installing and rotating the first batch of saw blades. The first turnover assembly 16 is located on the left side of the gantry frame 10. The first turnover assembly 16 includes a first feed cylinder 17 fixed on the pad 9. A first heat insulation seat 18 is fixed on the working end of the piston rod of the first feed cylinder 17. A first vehicle body 19 supported on the top surface of the pad 9 is fixed at the bottom of the first heat insulation seat 18. A stepped column 5 is fixed on the top surface of the first heat insulation seat 18. Rollers supported on the top surface of the pad 9 are provided on the bottom surface of the first vehicle body 19 and the bottom surface of the second vehicle body 23.
[0019] The pad 9 is provided with a second turnover assembly 20 for installing and rotating the second batch of saw blades. The second turnover assembly 20 is located on the right side of the gantry 10. The second turnover assembly 20 includes a second feed cylinder 21 fixed on the pad 9. A second heat insulation seat 22 is fixed on the working end of the piston rod of the second feed cylinder 21. A second car body 23 supported on the top surface of the pad 9 is fixed at the bottom of the second heat insulation seat 22. A stepped column 5 is fixed on the top surface of the second heat insulation seat 22.
[0020] A temperature sensor B24 is fixed on the top wall of the inner cavity of the heat-conducting inner bell jar 13. The signal line of the temperature sensor B24 passes through the top wall of the heat-conducting inner bell jar 13 and the top wall of the heat-insulating outer bell jar 12 in sequence and is connected to the controller.
[0021] The first turnover assembly 16 and the second turnover assembly 20 are symmetrically arranged about the left and right sides of the gantry frame 10. The lifting cylinder 11, the first feed cylinder 17 and the second feed cylinder 21 are all connected to the controller. The worker can control the extension or retraction of the piston rods of the lifting cylinder 11, the first feed cylinder 17 and the second feed cylinder 21 through the controller, thereby facilitating the worker's operation.
[0022] The method by which workers use this tempering device to temper the produced saw blades is as follows: S1. The worker takes out the first batch of saw blades 25 and fits the center hole 1 of the saw blade onto the stepped post 5 of the first turnover assembly 16, so that multiple saw blades are stacked on the stepped post 5, thereby realizing the installation of the first batch of saw blades 25 on the first turnover assembly 16. Figure 11 As shown; S2. The worker takes out the second batch of saw blades 26 and fits the center hole 1 of the saw blade onto the stepped post 5 of the second turnover assembly 20, so that multiple saw blades can be stacked on the stepped post 5, thereby realizing the installation of the second batch of saw blades 26 on the second turnover assembly 20. Figure 12 As shown; S3. Temper the first batch of saw blades at 25mm: S31. The worker controls the piston rod of the first feed cylinder 17 of the first turnover assembly 16 to extend to the right. The piston rod drives the first heat insulation seat 18 to move to the right. The first heat insulation seat 18 drives the first car body 19 to move to the right synchronously. The first car body 19 drives the first batch of saw blades 25 on it to move to the right synchronously. When the piston rod of the first feed cylinder 17 is fully extended, the first batch of saw blades 25 is just below the heat-conducting inner bell jar 13. Figure 13 As shown; S32. The worker controls the piston rod of the lifting cylinder 11 to move downwards. The piston rod drives the heat-insulating outer bell jar 12 and the heat-conducting inner bell jar 13 to move downwards synchronously. When the piston rod of the lifting cylinder 11 is fully extended, the bottom surface of the heat-insulating outer bell jar 12 and the bottom surface of the heat-conducting inner bell jar 13 are in contact with the top surface of the first heat-insulating seat 18. At the same time, the first batch of saw blades 25 are in the inner cavity of the heat-conducting inner bell jar 13. Figure 14 As shown; S33. The worker turns on the power supply, which is supplied to the heating coil 14 via wiring 15. After the heating coil 14 is energized, it generates heat to raise the temperature of the inner cavity of the heat-conducting inner bell jar 13, thereby gradually heating the first batch of saw blades 25. At the same time, the temperature sensor B24 monitors the temperature of the heat-conducting inner bell jar 13 in real time and transmits the temperature to the controller via the signal line. When the temperature sensor B24 detects that the temperature of the heat-conducting inner bell jar 13 reaches 350~400℃, the worker turns off the power supply, and the heating coil 14 stops heating the first batch of saw blades 25. S34. After the heat preservation period, the worker controls the piston rod of the lifting cylinder 11 to retract upwards. The piston rod drives the heat-insulating outer bell jar 12 and the heat-conducting inner bell jar 13 to move upwards, thereby resetting the heat-insulating outer bell jar 12 and the heat-conducting inner bell jar 13. S35. The piston rod of the first feed cylinder 17 of the first rotating assembly 16 retracts to the left. The piston rod drives the first heat insulation seat 18 to move to the left. The first heat insulation seat 18 drives the first vehicle body 19 to move to the left. The first vehicle body 19 drives the first batch of heated saw blades 25 to move to the left, so that the first batch of saw blades 25 moves to the initial position. The heat on the first batch of saw blades 25 is released to the outside. The heat dissipation direction is as follows: Figure 15As shown by the middle arrow, the first batch of saw blades 25 are gradually air-cooled; after the first batch of saw blades 25 are air-cooled to room temperature, the first batch of saw blades are finally tempered. During the air cooling process of the first batch of saw blades 25, the piston rod of the second feed cylinder 21 of the second rotating assembly 20 is simultaneously extended to the left, so that the second batch of saw blades 26 moves directly below the heat-insulating outer bell jar 12 and the heat-conducting inner bell jar 13. Figure 16 As shown; then the piston rod of the lifting cylinder 11 is extended downwards to place the second batch of saw blades 26 inside the heat-conducting inner bell jar 13, as shown. Figure 17 As shown; then the power is turned on to heat the second batch of saw blades 26 through the heating coil 14; after the second batch of saw blades 26 is heated, the piston rod of the lifting cylinder 11 is controlled to retract upward, and then the piston rod of the second feed cylinder 21 is controlled to retract to the right, so that the second batch of saw blades 26 moves to the initial position, and the heat on the second batch of saw blades 26 is gradually released to the outside, thereby gradually air-cooling the second batch of saw blades 26, and finally achieving tempering of the second batch of saw blades 26.
[0023] As can be seen from step S35, the first batch of saw blades 25 are air-cooled outside the heat-conducting inner bell jar 13. Therefore, the heat on the first batch of saw blades 25 can be released to the outside from all sides, compared to... Figures 3-6 The tempering furnace shown can only dissipate heat from the opening of the furnace body 3, making the heat dissipation of the first batch of saw blades 25 more uniform, thereby greatly improving the tempering quality of the saw blades. In addition, it also enables the first batch of saw blades 25 to be air-cooled to room temperature in a short time, thus not prolonging the tempering time of the second batch of saw blades 26, thereby greatly improving the tempering efficiency of the saw blades.
[0024] Furthermore, as can be seen from step S35, while the first batch of saw blades 25 is undergoing air cooling, the second batch of saw blades 26 is already being heated inside the heat-conducting inner bell jar 13, compared to... Figures 3-6 The tempering furnace shown requires the first batch of saw blades 25 in the furnace body 3 to be air-cooled to room temperature before the second batch of saw blades 26 can be heated. This avoids prolonging the tempering time of the second batch of saw blades 26 and greatly improves the tempering efficiency of the saw blades.
