Description

Technical Field

[0001] This utility model relates to the field of saw blade processing equipment, and in particular to a device for cleaning the surface of a saw blade substrate after quenching. Background Technology

[0002] In the saw blade manufacturing process, the quenching treatment of the saw blade substrate is one of the key steps. After quenching, the surface of the saw blade substrate is usually covered with a layer of black oxide scale, and a large amount of quenching oil is also attached, with the surface temperature reaching 50-60℃. If these residual impurities are not thoroughly cleaned, they will have a significant impact on subsequent processes: on the one hand, the presence of oxide scale will cause uneven stress on the substrate during pressure tempering, seriously affecting the flatness of the product; on the other hand, the quenching oil mixed with water remaining from the previous cooling process will accumulate in the tempering clamping environment, which may cause combustion inside the tempering furnace due to high temperature, posing a significant safety hazard.

[0003] Currently, traditional surface cleaning equipment after quenching mainly suffers from the following technical defects:

[0004] 1. Existing equipment mostly uses a single mechanical friction or simple air blowing method, which is difficult to completely remove quenching oil and stubborn oxide scale adhering to high temperature, especially the effect of treating sticky impurities at 50-60℃.

[0005] 2. For saw blade substrates of different thicknesses, the roller spacing of traditional equipment is fixed and cannot be automatically adjusted to adapt to diverse products, requiring frequent machine stops for adjustment, which affects production efficiency;

[0006] 3. The lack of an effective collection and treatment mechanism for the mixture of quenching oil and water leads to the accumulation of oily substances during tempering, which can easily cause safety accidents. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a surface cleaning device for saw blade substrate after quenching, which can adapt to high temperature environment, realize multi-stage cleaning of impurities, and automatically adjust the roller gap to adapt to the surface cleaning device of saw blade substrate with different thicknesses, so as to improve the quality of subsequent processes and ensure production safety.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A surface cleaning device for a quenched saw blade substrate includes side plates, a transmission roller, a cleaning roller, a first air blowing device, and a second air blowing device. The side plates are arranged parallel to each other at the discharge port of the quenching box. The transmission roller and the cleaning roller are arranged vertically between the side plates, with the cleaning roller positioned above the transmission roller. The first air blowing device and the second air blowing device are also arranged between the side plates. The first air blowing device is located on the right side of the side plate and close to the discharge port, while the second air blowing device is located on the left side of the side plate. A waste liquid tank is located below the side plates. After the saw blade substrate is discharged from the discharge port, it is horizontally conveyed by the transmission roller. It is first cleaned by the first air blowing device, then squeezed and cleaned by the cleaning roller, and finally cleaned a second time by the second air blowing device. The quenching oil and surface residue removed from the saw blade substrate fall into the waste liquid tank below.

[0010] In a preferred embodiment, the transmission rollers are arranged side by side between the side plates, with one side of the transmission roller penetrating the side plate and equipped with a transmission gear, allowing the transmission roller to rotate freely around its own axis; a transmission chain is sleeved on the outer wall of the transmission gear, and a transmission motor is connected to the end of the transmission chain.

[0011] In a preferred embodiment, a placement groove is provided on the inner side of the side plate, and sliding grooves are provided on both sides of the placement groove. A fixing block and a sliding block are provided in the placement groove. The fixing block is fixedly provided at the bottom of the placement groove, and the sliding block is provided above the fixing block. The two sides of the sliding block are engaged in the sliding groove and slide along the sliding groove for limitation.

[0012] In a preferred embodiment, the side of the fixed block is rotatably connected to the other end of the transmission roller via a bearing seat.

[0013] In a preferred embodiment, the side of the sliding block is fixedly connected to both sides of the cleaning roller, and a compression spring is connected between the top of the sliding block and the placement groove.

[0014] In a preferred embodiment, both the first and second air-blowing devices include an air-blowing plate and a rotating shaft; the two ends of the rotating shaft pass vertically through the side plate and can rotate freely around its own axis, and the side of the rotating shaft is connected to the air-blowing plate; the side of the air-blowing plate is provided with an air outlet, the air-blowing plate is connected to an air supply pipe, and the other end of the air supply pipe is connected to an external air source.

[0015] In a preferred embodiment, the end of the rotating shaft is configured as a threaded rod, and the threaded clamp plate has a threaded hole at its center and is threadedly connected to the threaded rod to clamp and fix the rotating shaft to the side plate.

[0016] In a preferred embodiment, the contact surface between the threaded clamp and the side plate is engraved with grooves.

[0017] A device for cleaning the surface of a saw blade substrate after quenching has the following advantages in practical use:

[0018] 1. The equipment adopts a three-stage treatment process of "pre-washing → extrusion cleaning → secondary washing": the initial washing removes loose impurities and some quenching oil from the surface; the intermediate extrusion rollers use mechanical friction to peel off stubborn oxide scale and sticky oil film; and the final secondary washing thoroughly removes residual debris. The multi-stage cleaning creates a synergistic effect of mechanical force and airflow, significantly improving the oxide scale removal effect and quenching oil removal rate, providing a clean surface for the subsequent pressurized tempering process, and effectively improving the flatness of the product;

[0019] 2. The cleaning roller, through a flexible connection structure, engages with the side plate and can automatically adjust the distance between itself and the transmission roller according to the thickness of the saw blade substrate. When substrates of different thicknesses pass through, the adaptive adjustment of the flexible structure ensures that the roller surface maintains effective contact pressure with the substrate, adapting to diverse products without requiring machine downtime for adjustment, significantly improving production continuity and equipment applicability;

[0020] 3. The transfer rollers and cleaning rollers are made of high-temperature resistant materials, which can withstand the temperature of the substrate after quenching for a long time, avoiding equipment performance degradation caused by high temperature and extending the service life of key components. The waste liquid tank below is designed to collect quenching oil, water mixture and residue in a centralized manner, reducing the accumulation of oily substances in the tempering environment and effectively reducing safety hazards caused by oil volatilization;

[0021] 4. The blowing device achieves flexible adjustment of the air outlet angle through a rotating shaft and clamping structure. It can accurately adjust the blowing direction according to the distribution characteristics of impurities on the substrate surface, ensuring that impurities in different areas can be effectively cleaned, further enhancing the device's flexibility and cleaning efficiency.

[0029] like Figure 1 and Figure 2 As shown, a surface cleaning device for a saw blade substrate after quenching includes side plates 2, a transmission roller 3, a cleaning roller 4, a first air blowing device 7, and a second air blowing device 8. The side plates 2 are arranged parallel to each other at the discharge port 6 of the quenching box 1. The side plates 2, made of Q235B steel, are fixed to both sides of the quenching box 1 with bolts to form a stable support frame. The transmission roller 3 and the cleaning roller 4 are vertically arranged between the side plates 2, with the cleaning roller 4 positioned above the transmission roller 3. Both are made of high-temperature resistant 304 stainless steel and have been hard chrome plated to enhance wear resistance. The first air blowing device 7 and the second air blowing device 8 are also arranged between the side plates 2. The first air blowing device 7 is located on the right side of the side plate 2 and close to the discharge port 6, while the second air blowing device 8 is located on the left side of the side plate 2. A waste liquid tank 5 with an inclined bottom surface of 15° is arranged below the side plates 2 to facilitate waste disposal. Liquid flow: After the saw blade base 23 is sent out from the discharge port 6, it is horizontally conveyed by the transmission roller 3. First, the first blowing device 7 introduces compressed air of 0.4-0.6MPa to blow and clean it. The airflow speed can reach 20-30m / s. Then, it is squeezed and cleaned through the squeezing gap formed by the cleaning roller 4 and the transmission roller 3 (initial gap 1mm, which can be adaptively adjusted). Finally, it is blown and cleaned a second time by the second blowing device 8 at an inclination angle of 15°. The quenching oil and surface residue that are cleaned fall into the waste liquid tank 5 below under the action of gravity.

[0030] Preferred solutions include Figure 2 As shown, the transmission rollers 3 are arranged side by side between the side plates 2. One side of the transmission roller 3 passes through the side plate 2 and is equipped with a transmission gear 11. The transmission roller 3 can rotate freely around its own axis, and its shaft end is rotatably connected to the side plate 2 through a deep groove ball bearing. The outer wall of the transmission gear 11 is fitted with a transmission chain 10, and the end of the transmission chain 10 is connected to a servo drive motor 9. The speed of the motor can be adjusted in the range of 50-200 rpm by a frequency converter. The transmission motor 9 drives the transmission chain 10 to rotate, thereby driving the transmission gear 11 to rotate synchronously with the transmission roller 3, and smoothly conveying the saw blade base 23 at a speed of 0.5-2 m / min to ensure sufficient cleaning time.

[0031] Preferred solutions include Figure 3As shown, a rectangular placement groove is provided on the inner side of the side plate 2. T-shaped sliding grooves 14 are provided on both sides of the placement groove. A fixing block 12 and a sliding block 15 are installed within the placement groove. The fixing block 12 is fixed to the bottom of the placement groove with M8 bolts. The sliding block 15 is positioned above the fixing block 12, with its two sides engaging within the sliding groove 14 and sliding vertically along the groove 14. The guide length of the sliding groove 14 is 50mm, accommodating saw blade substrates of different thicknesses. A helical compression spring 16 is connected between the top of the sliding block 15 and the placement groove. The compression spring 16 is made of 65Mn spring steel and can provide an elastic support force of 50-150N through pre-compression adjustment. When saw blade substrates 23 of different thicknesses pass through, the compression spring 16 drives the sliding block 15, causing the cleaning roller 4 to slide vertically and adaptively along the sliding groove 14. This ensures that the gap between the cleaning roller 4 and the transmission roller 3 dynamically adjusts with the substrate thickness, maintaining a stable contact pressure for effective squeezing and cleaning.

[0032] Preferred solutions include Figure 3 As shown, the side of the fixed block 12 is rotatably connected to the other end of the transmission roller 3 through a cast iron bearing seat 13. The bearing seat 13 is equipped with a self-aligning roller bearing, which allows the transmission roller 3 to automatically align itself when rotating at high speed, thereby reducing transmission vibration.

[0033] Preferred solutions include Figure 3 As shown, the side of the sliding block 15 is fixedly connected to the two sides of the shaft end of the cleaning roller 4 by positioning pins. A helical compression spring 16 is connected between the top of the sliding block 15 and the placement groove. The compression spring 16 is made of 65Mn spring steel with an elastic coefficient of 20-50N / mm. The pre-compression amount can be adjusted to provide a contact pressure of 50-150N to ensure that the cleaning roller 4 and the surface of the saw blade base 23 are tightly attached.

[0034] Preferred solutions include Figure 4 As shown, both the first air blowing device 7 and the second air blowing device 8 include an air blowing plate 17 and a rotating shaft 18. The two ends of the rotating shaft 18 penetrate the side plate 2 vertically and can rotate freely around its own axis. The surface of the shaft is heat-treated to achieve a hardness of HRC35-40. The side of the rotating shaft 18 is connected to the air blowing plate 17 by welding. The side of the air blowing plate 17 has 10 air outlets with a diameter of 3mm evenly distributed. The air blowing plate 17 is connected to the air supply pipe 19 through a quick-connect connector. The air supply pipe 19 is made of high-temperature resistant silicone hose, and its other end is connected to the factory compressed air pipeline network.

[0035] Preferred solutions include Figure 5As shown, the end of the rotating shaft 18 is configured as a threaded rod 20 with a pitch of 1.5mm. The threaded clamp 21 has a matching internal threaded hole at its axis and is threadedly connected to the threaded rod 20. The angle of the blower plate 17 can be adjusted by rotating the threaded clamp 21 (adjustment range 0-60°) to clamp and fix the rotating shaft 18 to the side plate 2. The contact surface between the threaded clamp 21 and the side plate 2 is engraved with a groove 22 with a depth of 2mm. The groove adopts a sawtooth pattern design, which can increase the friction of the contact surface and ensure that the blowing angle is stably fixed after the threaded clamp 21 clamps the rotating shaft 18, avoiding angle deviation caused by vibration.
