Abstract
Description
Technical Field
[0001] The utility model relates to the field of sawing metal tools, in particular to a carbide band saw blade welding machine. Background Art
[0002] Bimetallic band saw blade is a special metal cutting tool, and its preparation process integrates a variety of high-tech metal processing and welding technologies. Its core lies in carefully forging high-speed steel or other steels with excellent performance into tooth tip blocks, and closely combining them with spring steel strips through precise welding processes. This process is not just a simple connection, but also a deep optimization and improvement of material properties.
[0003] After welding, the saw teeth are finely shaped to ensure that each tooth meets strict standards. After quenching and tempering, the performance of the saw blade material is further improved, and the hardness, wear resistance and red hardness have reached extremely high levels.
[0004] The tip of the bimetal band saw blade is made of high-performance materials such as high-speed steel or carbide. These materials have excellent hardness and wear resistance, ensuring that the saw blade can still maintain excellent performance in a long-term, high-intensity working environment. The backing material is spring steel, which provides a stable support for the saw blade with its high strength, good toughness and excellent fatigue resistance.
[0005] As an efficient cutting tool, bimetallic band saw blades have obvious advantages over other tools. They can not only achieve efficient sawing, but also process large-sized materials while ensuring narrow cutting kerfs and high cross-section accuracy. Therefore, they are widely used in the industrial field. In recent years, with the continuous advancement of manufacturing technology, the market demand for bimetallic band saw blades has also been growing year by year.
[0006] However, although the preparation technology of bimetallic band saw blades is quite mature, there are still some technical problems in the welding link between the tooth tip block and the backing material during its processing. At present, the main welding processes include electron beam welding, resistance butt welding and laser welding. Among them, although electron beam welding has high welding quality, it needs to be carried out in a vacuum environment, which means that cumbersome vacuuming operations are required every time the machine is turned on, which greatly reduces production efficiency. In addition, electron beam welding equipment is expensive, and the daily repair and maintenance costs are also quite high, which undoubtedly increases the operating costs of the enterprise.
[0007] The resistance welding device also faces some challenges in the welding process of bimetallic band saw blades. Although resistance welding has the advantages of easy operation and low cost, it is easy to cause unstable welding quality, cold welding, desoldering and other problems during the welding process.

[0036] Example 1, please refer to Figure 1-2 As shown:
[0037] A carbide band saw blade tooth welding machine, comprising a welding device 110 arranged on a supporting platform 100; the welding device 110 comprises a rotatable welding head 111; the welding head 111 picks up tooth particles from a discharging mechanism 170 and then rotates to abut against a saw blade backing material 101 to weld the tooth particles to the saw blade backing material 101; the welding head 111 is provided with an air suction hole, and the tooth particles are adsorbed on the welding head 111 by vacuum suction to complete the picking of the tooth particles, the welding head 111 is driven to rotate by a motor, and the tooth particles on the welding head 111 are abutted against the saw blade backing material 101 by resistance welding to complete the welding, and because the welding head 111 is arranged at an angle to the saw blade backing material 101, after the welding head 111 rotates, the tooth particles can be abutted against the saw blade backing material 101 by rotary pressure, thereby improving the tightness during contact, avoiding cold welding, and improving the welding quality;
[0038] In one embodiment, a telescopic mechanism may be provided on the top of the welding head 111. After the welding head 111 is rotated into position, the tooth particles are pressed against the saw blade backing material 101 by the telescopic mechanism to improve the welding quality. However, the structure is more complicated than the rotating abutment pressure structure.
[0039] A support assembly 130 is provided on the other side of the saw blade backing material 101 relative to the welding device 110. The support assembly 130 abuts against the other side of the saw blade backing material 101 relative to the welding tooth particles, and can provide support when the welding machine head 111 abuts the tooth particles against the saw blade backing material 101 or when the saw blade backing material 101 is subjected to force; further, two support assemblies 130 are provided to ensure the stability of the abutment;
[0040] A pressing plate 120 is also provided on the support platform 100 near the welding device 110. After the saw blade backing material 101 is moved to a suitable position, the pressing plate 120 presses down to fix the saw blade backing material 101, thereby improving the bending resistance of the saw blade. The pressing plate 120 is arranged close to the welding device 110, and the position where the welding machine head 111 abuts against the saw blade backing material 101 is also close to the pressing plate 120, which can effectively reduce the deformation of the saw blade backing material 101 during welding and ensure the welding quality. Furthermore, the support platform 100 is provided with a pressing plate 120. A clamping assembly 140 is provided, and the clamping assembly 140 has the same function as the pressing plate 120, and is also used to clamp the saw blade backing material 101 after the saw blade backing material 101 is in place; the pressing plate 120 is controlled to move up and down by the lifting cylinder 160; in one embodiment, the pressing plate 120 and the clamping assembly 140 are connected to the lifting cylinder 160 at the same time, and the lifting cylinder 160 simultaneously controls the lifting of the pressing plate 120 and the clamping assembly 140 to clamp and fix the saw blade backing material 101;
[0041] The support platform 100 is also connected to a guide roller 150 for guiding the saw blade backing material 101;
[0042] The feeding mechanism for conveying the saw blade backing material 101 belongs to the prior art in this field and will not be described in detail here and is not shown in the drawings.

When the welding head 111 of the welding device 110 rotates to the discharge mechanism 170, the particle pushing mechanism 175 pushes a single tooth particle out, so that it is picked up by the welding head 111;
[0044] In one embodiment, a top cover 174 is provided on one side of the particle conveying channel 173 close to the discharge port 172, and the distance between the top cover 174 and the bottom of the particle conveying channel 173 is adapted to the height of the tooth particles, and the width of the particle conveying channel 173 is also adapted to the width of the tooth particles, so that the tooth particles can be effectively limited to ensure that the tooth particles do not tip over or tilt in the particle conveying channel 173; the top of the side of the particle output channel close to the particle pushing mechanism 175 is open, so that the working status of the tooth particles and the operation of the particle pushing mechanism can be checked, which is convenient for inspection and maintenance when abnormal conditions occur, and it is also convenient to check whether the number of tooth particles in the particle conveying channel 173 is sufficient.
[0045] When the tooth welding machine of the utility model is working, an electrode sheet serving as a negative electrode is provided on the welding head 111, and the electrode sheet is electrically connected to the tooth particles to be welded. The pressing plate 120 can serve as a positive electrode. After the welding head 111 grabs the tooth particles, the tooth particles are abutted against the saw blade backing material 101, and the tooth particles are welded to the saw blade backing material 101 after power is turned on.
[0046] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
