Description

Technical Field

[0001] This utility model relates to the field of metal abrasive processing, specifically to a metal abrasive cutting device with quantitative feeding. Background Technology

[0002] Currently, in the processing of metal abrasives, it is often necessary to cut metal rods. During the cutting process, the metal abrasive needs to be continuously fed to achieve continuous cutting at different positions. However, in the existing technology, when performing waterjet cutting on rod-shaped metal abrasives, the clamping and fixing parts of the metal abrasive are fixed. Therefore, each time the metal abrasive is fed, the clamping and fixing structure needs to be loosened and then clamped again, which affects the working effect. Moreover, the feed amount of each feed needs to be measured, which is prone to errors and affects the accuracy of waterjet cutting. Therefore, a metal abrasive cutting device with quantitative feeding is proposed. Utility Model Content

Three cylinders clamp and fix the left end of the abrasive. When feeding is required, a servo motor is activated. The servo motor drives a worm gear to rotate, which in turn drives a spur gear via a rotating shaft. The spur gear's rotation causes a rack to move laterally, which in turn moves a crossbar laterally. The crossbar then moves the cylinder to the right, and the cylinder moves the metal abrasive to the right, thus feeding the abrasive. Each feeding operation controls the number of rotations of the worm gear driven by the servo motor, thereby controlling the distance the crossbar moves to the right and ultimately the feed rate of the abrasive. This eliminates the need for manual measurement, preventing errors. This device facilitates feeding the abrasive without repeated disassembly and assembly, improving work efficiency and allowing for precise control of the abrasive feed rate. It also eliminates the need for manual measurement, preventing errors and improving the accuracy of waterjet cutting, making it user-friendly. Attached Figure Description

A cutting component can be installed on the upper right side of the horizontal plate 1. The cutting component can be one of a cutting wheel, a laser cutting component, or a water jet cutting component, depending on actual needs. As prior art, it is not shown in the figure.

[0017] In order to install metal abrasives, such as Figure 2 As shown, the clamping mechanism includes multiple cylinders (6), which are evenly distributed in a ring on the outer sidewall of the cylinder (2), and the moving end of each cylinder (6) extends slidably into the interior of the cylinder (2). The number of cylinders (6) is set to three, which facilitates clamping and fixing the end of the rod-type metal abrasive.

[0018] To guide the lateral movement of cylinder 2 and make its lateral movement more stable, such as... Figure 1 and Figure 2 As shown, a limiting slider (7) is fixedly provided on the lower side of the cylinder (2), and a limiting groove is provided on the upper side of the horizontal plate (1) for the limiting slider (7) to slide.

[0019] To guide the lateral movement of crossbar 3, such as Figure 3 As shown, each of the square openings has guide wheels (8) rotatably mounted on the front and rear sides via a second rotating shaft. The crossbar (3) has guide grooves on the front and rear sides for the guide wheels (8) to roll, which makes the crossbar (3) more stable when moving laterally.

[0020] In order to drive the spur gear 5 to rotate, such as Figure 1 and Figure 3As shown, the drive mechanism includes a servo motor (9), a worm gear (10), and a worm (11). The front end of the rotating shaft extends forward and is fixedly connected to the worm gear (10). The servo motor (9) is fixedly installed on the lower left side of the horizontal plate (1). The output shaft of the servo motor (9) passes through the horizontal plate (1) through a bearing and is fixedly connected to the worm (11). The worm (11) meshes with the worm gear (10). When the servo motor (9) is started, the servo motor (9) drives the worm gear (10) to rotate through the worm gear (11). The worm gear (10) drives the spur gear (5) to rotate through the rotating shaft. The rotation of the spur gear (5) can drive the rack (16) to move laterally. The rack (16) drives the horizontal bar (3) to move laterally. The horizontal bar (3) drives the cylinder (2) to move to the right. The cylinder (2) drives the metal abrasive to move to the right, thereby enabling the feeding of the metal abrasive.

[0021] To support the other end of the metal abrasive, such as Figure 1 and Figure 4 As shown, the support mechanism includes a support plate (12), an adjusting bolt (13), two guide rollers (14), and two guide rods (15). The support plate (12) is located on the upper right end of the horizontal plate (1). A V-shaped groove is provided on the upper side of the support plate (12). A strip groove is provided on both inclined surfaces of the V-shaped groove. The two guide rollers (14) are rotatably disposed in the two strip grooves through a third rotating shaft. The two guide rollers (14) are distributed in a V-shape. A threaded hole is provided on the upper right side of the horizontal plate (1) and is threadedly connected to the adjusting bolt (13). The upper end of the adjusting bolt (13) is connected to the support through a bearing seat. The lower side of the plate (12) is rotatably connected, and two guide holes are also opened on the upper right side of the horizontal plate (1), which are symmetrically distributed front and back. The two guide rods (15) are vertically slidably arranged in the two guide holes, and the upper ends of the two guide rods (15) are fixedly connected to the bottom of the support plate (12). By rotating the adjusting bolt 13, the support plate 12 can be driven to move vertically. The support plate 12 drives the two guide rollers 14 to move vertically, so that the guide rollers 14 can support the metal abrasive, thereby improving the stability of the metal abrasive during water jet cutting. The two guide rollers 14 facilitate the sliding of the metal abrasive on the support plate 12.

[0022] In use, the left end of a rod-shaped metal abrasive is inserted into the cylinder 2. Three cylinders 6 clamp and fix the left end of the abrasive. When feeding is required, the servo motor 9 is activated. The servo motor 9 drives the worm gear 10 to rotate via the worm 11. The worm gear 10 drives the spur gear 5 to rotate via the shaft. The rotation of the spur gear 5 causes the rack 16 to move laterally. The rack 16 drives the crossbar 3 to move laterally, and the crossbar 3 drives the cylinder 2 to move to the right. The cylinder 2 then drives the metal abrasive to move to the right, thus enabling feeding of the metal abrasive. Each feeding operation controls the number of rotations of the worm 11 driven by the servo motor 9, thereby controlling the distance the crossbar 3 moves to the right and the feed amount of the metal abrasive. No manual measurement is required, avoiding errors. This device facilitates feeding of the metal abrasive without repeated disassembly and assembly, improving work efficiency. It also facilitates control of the metal abrasive feed amount, eliminating the need for manual measurement and preventing errors, thus improving the accuracy of waterjet cutting and making it convenient for users.
