Description

Technical Field

[0001] The present invention relates to the technical field of saw blade production and processing, and in particular to a production process of alloy saw blades. Background Art

[0002] Alloy saw blades are the most commonly used cutting tools in wood processing. Their quality is closely linked to the quality of the finished product. Choosing the right alloy saw blade is crucial for improving product quality, shortening processing cycles, and reducing costs. An alloy saw blade's various parameters, including the type of alloy head, base material, diameter, number of teeth, thickness, tooth profile, angle, and aperture, determine its processing capabilities and cutting performance.

[0003] The saw blade mainly consists of two parts: a saw disc and saw teeth. The saw teeth are fixed to the saw disc by welding with metal welding pieces. The current production process is: first install the metal welding piece on the saw tooth, then push the saw tooth and the metal welding piece together to the tooth position of the saw disc and fix it, and then perform the welding operation. This production process requires completing the welding operation of the previous saw tooth before rotating the saw disc and repeating the above operation to weld the next saw tooth. This method of welding the saw teeth one by one is cumbersome and labor-intensive. In addition, this processing method requires the welding station on the welding equipment to remain in operation for a long time, which greatly increases the energy consumption cost of the equipment and is not in line with the development concept of green environmental protection. Summary of the Invention

[0004] The purpose of the present invention is to provide an alloy saw blade production process, which has high processing efficiency and low energy consumption, thereby reducing the production cost of the enterprise and is more in line with the enterprise's green and environmentally friendly development concept.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A production process for alloy saw blades, characterized in that the specific steps include:

[0006] S1, cutting the plate into saw disc shape;

[0007] S2, placing the saw disc into a roller press for roller pressing to ensure the verticality of the saw disc;

[0008] S3, grinding both surfaces of the saw disc;

[0009] S4, sending the saw blade into the oven to bake to increase the hardness of the saw blade;

[0010] S5. Using processing equipment, assemble the metal welding sheet and the saw teeth at the tooth opening of the saw disk, and rely on the assembly fixing structure formed between the three to achieve the fixation of the metal welding sheet, the saw teeth and the saw disk, and drip a flux between each two of the three, and then complete the installation of all the saw teeth on the same saw disk in sequence;

[0011] S6. Place the saw disc with the installed saw teeth into the welding mold, drive each saw tooth to press against the saw disc through the pressing mechanism provided in the welding mold, and then control the welding station on the welding equipment to approach the saw teeth to perform the welding operation;

[0012] S7, sandblasting the saw blade after welding to clean the surface of the saw blade;

[0013] S8, grinding and tapering each saw tooth using a grinding wheel;

[0014] S10, cleaning the surface of the saw blade.

[0015] By adopting the above technical solution, an assembly fixing structure is formed between the metal welding sheet, the saw teeth and the saw disk, and processing equipment is used to realize the pre-assembly fixation between the three, so that the three can be kept in an assembled state for transmission. Then the three parts kept in the assembled state are placed in the welding mold, and the pressing mechanism on the welding mold is used to drive each saw tooth to press against the metal welding sheet and the saw disk in turn, so as to ensure the tightness of the assembly between the three and prevent the saw teeth from being misaligned or falling off after the metal welding sheet melts during the welding process. Then the welding station on the welding equipment is controlled to synchronously weld all the saw teeth on the saw disk. Through this setting structure, the operating time of the welding station on the welding equipment can be reduced under the premise of the same workload. The above-mentioned process improvement makes the processing efficiency of the production process higher and the energy consumption lower, thereby reducing the production cost of the enterprise and being more in line with the enterprise's green and environmentally friendly development concept.

[0016] The method is further configured to include the step S9, manually striking the saw blade processed in step S8 with a hammer to correct the uneven position on the saw disc, and using a linear ruler to calibrate and inspect the saw blade after the striking until it is qualified.

[0017] By adopting the above technical solution, the saw blade after processing is further corrected, so as to ultimately ensure the production quality of the saw blade and better reduce the defective rate.

[0018] It is further configured as follows: the assembly and fixing structure includes a left embedding groove arranged on one side of the metal welding plate and a right embedding groove arranged on the other side of the metal welding plate, the saw teeth are embedded in the left embedding groove and tightly fixed to the left embedding groove, and the saw disk is embedded in the right embedding groove and tightly fixed to the right embedding groove.

[0019] By adopting the above technical solution, the saw disc is inserted into the right groove and fixed together through a tight fit, while the saw teeth are inserted into the left groove and fixed together through a tight fit, thus completing the assembly and fixation of the three components. This simple groove assembly structure only requires processing of the metal welding sheet, which reduces processing costs. The technology of assembling the three components using existing processing equipment is also a well-known technical means.

[0020] It is further configured as follows: the left embedding groove and the right embedding groove are arranged correspondingly, and the metal welding sheet is provided with a liquid storage hole which communicates with the left embedding groove and the right embedding groove and is used for storing the flux.

[0021] By adopting the above technical solution, the provision of a liquid reservoir can better store the flux between the metal welding sheet, the saw teeth, and the saw disc, thereby improving the flux retention and preventing the flux from leaking during transportation through the processing equipment, thereby ensuring the quality of subsequent welding. Furthermore, because the liquid reservoir connects the left and right embedded grooves, the operation of dripping the flux between the metal welding sheet, the saw teeth, and the saw disc is reduced from two dripping operations to a single dripping operation, thereby improving processing efficiency and reducing processing costs.

[0022] It is further configured as follows: an installation groove for installing the saw blade is formed on the welding mold, and a locking assembly for fixing the saw blade is provided on the welding mold. When the saw blade is installed in the installation groove, the welding mold is provided with a notch communicating with the outside world at a position corresponding to the saw teeth along the axis of the saw disk.

[0023] By adopting the above technical solution, the setting of the locking component can firmly fix the saw blade on the welding mold, and the formed gap can prevent the existing welding mold from interfering with the welding operation of the subsequent welding station.

[0024] It is further configured as follows: the clamping mechanism includes a clamping rod rotatably arranged on the welding mold and located on one side of the saw blade on the welding mold, and the clamping rod is arranged between each adjacent saw teeth, a linkage disk rotatably arranged on one side of the welding mold, a driving member driving the linkage disk to rotate, and a linkage assembly that constitutes the linkage between each clamping rod and the linkage disk, one end of the clamping rod extends between adjacent saw teeth and reciprocates between adjacent saw teeth.

[0025] By adopting the above technical solution, the saw blade is mounted on the welding mold and each abutment rod is positioned between adjacent saw teeth. The driving member drives the linkage disk in conjunction with the linkage assembly to drive each abutment rod to rotate synchronously, driving the saw teeth to press against the saw disk. This achieves a tightening operation on each saw tooth, ensuring a tight fit between the metal welding sheet, the saw teeth, and the saw disk. It also prevents the saw teeth from shifting after the metal welding sheet melts at high temperatures, thereby ensuring the quality of subsequent welding.

[0026] It is further configured as follows: the linkage component includes a linkage waist-shaped hole arranged on the linkage disk and a linkage rod fixedly arranged on the tightening rod and extending into the linkage waist-shaped hole, and the linkage waist-shaped hole is extended along the radial direction of the saw disk.

[0027] By adopting the above technical solution, the linkage waist-shaped hole cooperates with the linkage rod to form the linkage between each tightening rod and the linkage disk. This setting has a simple structure and low processing cost.

[0028] It is further configured as follows: the locking assembly includes a shaft rod fixedly arranged in the mounting slot and used to pass through the shaft hole on the saw disc, a limiting rod fixedly arranged in the mounting slot, a limiting hole formed on the saw disc and for the limiting rod to pass through, and a locking nut threadedly connected to the shaft rod. When the saw disc is installed on the shaft rod, the limiting rod passes through the limiting hole to limit the circumferential rotation of the saw disc.

[0029] By adopting the above technical solution, the saw blade is aligned with the limit rod and the limit hole during the process of being installed into the shaft, so that the limit rod can pass through the limit hole to limit the saw blade in the circumferential direction, and then the locking nut can be tightened to complete the fixed installation operation of the saw blade on the welding mold.

[0030] It is further configured as follows: the welding stations on the welding equipment are an upper induction heating coil and a lower induction heating coil located on both sides of the welding mold, and both the upper induction heating coil and the lower induction heating coil are provided with an annular heating section corresponding to the sawtooth distribution position.

[0031] By adopting the above technical solution, this setting structure can form an effective high-temperature welding heating zone to ensure welding quality, and through the formed annular heating section, it can ensure that the high-temperature welding heating zone can contact each saw tooth.

[0032] In summary, the present invention has the following beneficial effects: the present invention has high processing efficiency and low energy consumption, thereby reducing the production cost of the enterprise and being more in line with the enterprise's green and environmentally friendly development concept.
