Description

Technical Field

[0001] This utility model relates to the technical field of wire saws, and in particular to a multi-tooth wire saw and its dedicated processing device. Background Technology

[0002] Wire saws, as a common linear cutting tool, are widely used in woodworking, model making, and jewelry processing due to their flexible blades and ability to cut curves. Currently, most wire saws on the market typically have unidirectional, continuous saw teeth at a single angle on a single wire, achieving cutting through continuous scraping motion. However, when processing materials such as shells or other high-hardness, brittle materials, traditional wire saws have low cutting efficiency, and the cutting process can become choppy when encountering hard points within the material, easily leading to material breakage. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-tooth wire saw and its special processing device, which can process saw teeth with multiple angles and staggered arrangement on the surface of the saw blade, so that the wire saw can process high-hardness and brittle materials such as shells more efficiently and smoothly.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a multi-tooth wire saw, including a saw blade and a handle, the two ends of the saw blade are fixed on the handle, and multiple sets of saw teeth are provided on the surface of the saw blade at intervals along the circumferential direction of the saw blade. Each saw tooth set contains multiple saw teeth, and the saw teeth in each saw tooth set are staggered on the surface of the saw blade.

[0005] Furthermore, the saw tooth group consists of at least five groups, which are evenly distributed along the circumference of the saw blade, and the saw teeth in adjacent groups are axially staggered.

[0006] Furthermore, the saw blade is made of spring steel wire or stainless steel wire, and the diameter of the saw blade is 0.5 mm.

[0007] A special processing device for a multi-tooth wire saw includes a worktable, on which a processing block is fixed. The processing block has a processing groove, the depth of which is the same as the depth of the saw teeth. An angle adjustment component is fixed on the worktable, which is used to change the angle to be processed of the saw blade.

[0008] Furthermore, the worktable is provided with an installation groove, the processing block is installed in the installation groove, and the upper surface of the processing block is flush with the upper surface of the worktable. The worktable is provided with a positioning groove, and the positioning groove and the processing groove are located on the same straight line.

[0009] Furthermore, the angle adjustment component includes a first mounting hole, a second mounting hole, and a third mounting hole formed on the worktable. The first mounting hole, the second mounting hole, and the third mounting hole are staggered. A first stop rod is fixed in the first mounting hole, a second stop rod is fixed in the second mounting hole, and a third stop rod is fixed in the third mounting hole. The length of the first stop rod is shorter than the length of the second stop rod, and the length of the second stop rod is shorter than the length of the third stop rod.

[0010] Furthermore, the processing block is provided with a scale groove, which is located on both sides of the processing groove. The scale groove facilitates the determination of the position of the saw teeth when processing the saw blade.

[0011] Compared with the prior art, the advantages of this utility model are that by setting multiple angled and axially staggered sets of interlaced saw teeth on the circumferential surface of the saw blade, a multi-directional cutting edge is formed, which increases the cutting area and force, thereby enabling faster and smoother cutting of hard and brittle materials such as shells; in addition, the special processing device, by setting processing blocks and angle adjustment components, enables the device to quickly and accurately position the saw blade and adjust its processing angle, ensuring that multiple angled and precisely positioned interlaced saw teeth are orderly pressed on the thin steel wire, solving the problem that this type of special saw blade is difficult to manufacture by hand.

Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1-5As shown, a multi-tooth wire saw includes a saw blade 1 and a handle 2. The two ends of the saw blade 1 are fixed to the handle 2. At least five sets of saw teeth are provided on the surface of the saw blade 1. The saw teeth are distributed at equal angles along the circumference of the saw blade 1, forming a multi-directional cutting edge. This allows the saw teeth in all directions to participate in cutting when the saw blade 1 reciprocates, increasing the cutting area and force. This enables faster and smoother cutting of hard materials such as shells and jade. Each saw tooth set contains multiple saw teeth 11. The saw teeth 11 in adjacent saw tooth sets are axially staggered, so that each saw tooth 11 is staggered on the surface of the saw blade 1. The staggered saw teeth 11 form a staggered cutting surface. When encountering hard points or impurities inside the material, the impact force is dispersed to the saw teeth 11 in different directions, avoiding stress concentration and reducing the risk of the saw blade 1 jamming. In this embodiment, the saw blade 1 is made of spring steel wire or stainless steel wire, and the diameter of the saw blade 1 is 0.5 mm.

[0015] A special processing device for processing the multi-tooth wire saw of this embodiment includes a worktable 3, on which a mounting groove 31 is formed. A processing block 4 is fixed in the mounting groove 31. The upper surface of the processing block 4 is flush with the upper surface of the worktable 3. The processing block 4 has a processing groove 41 and a scale groove 42, with the scale groove 42 located on both sides of the processing groove 41. The depth of the processing groove 41 and the scale groove 42 is the same as the depth of the saw teeth 11. A positioning groove 32 is formed on the worktable 3, and the positioning groove 32 is located on the same straight line as the processing groove 41. An angle adjustment component 5 is fixed on the worktable 3 for angle adjustment. Component 5 is used to change the angle to be processed of saw blade 1. The angle adjustment component 5 includes a first mounting hole 51, a second mounting hole 52 and a third mounting hole 53 opened on the worktable. The first mounting hole 51, the second mounting hole 52 and the third mounting hole 53 are staggered. A first stop bar 511 is fixed in the first mounting hole 51, a second stop bar 521 is fixed in the second mounting hole 52 and a third stop bar 531 is fixed in the third mounting hole 53. The length of the first stop bar 511 is shorter than the length of the second stop bar 521 and the length of the second stop bar 521 is shorter than the length of the third stop bar 531.

[0016] The process of machining a multi-tooth wire saw using a specialized machining device is as follows: Place the saw blade 1 in the machining groove 41 on the machining block 4, and position the handle 2 against the front of the first stop bar 511 in the angle adjustment assembly 5 (with the operator facing the stop bar as the reference). At this time, the saw blade 1 is at the first preset machining angle in the machining groove 41. Use an external tool (such as a file) to perform the first machining on the saw blade 1 according to the corresponding scale groove 42, forming the first set of saw teeth. Place the handle 2 against the front of the second stop bar 521. This operation changes the angle of the saw blade 1 in the machining groove 41 to the second preset machining angle. Use an external tool to perform the first machining on the saw blade 1 according to the corresponding scale groove 42, forming the first set of saw teeth. Place the handle 2 against the front of the second stop bar 521. This operation changes the angle of the saw blade 1 in the machining groove 41 to the second preset machining angle. The groove 42 performs a second processing on the saw blade 1 to form a second set of saw teeth. The second set of saw teeth is equiangularly distributed with the first set of saw teeth in the circumferential direction, and the saw teeth 11 in the second set of saw teeth are axially misaligned with the saw teeth 11 in the first set of saw teeth. The handle 2 is then moved toward the front of the third stop 531, and the back of the first stop 511, the second stop 521, and the third stop 531 in sequence (these positions correspond to different processing angles). Under each angle positioning, the processing cycle of a complete set of saw teeth is repeated to finally process at least five sets of saw teeth that are equiangularly distributed along the circumference and whose saw teeth 11 are axially misaligned on the circumferential surface of the saw blade 1.
