Description

Technical Field

[0001] This application relates to the field of circular saws, and more particularly to a feeding device for a circular saw. Background Technology

[0002] A circular saw is a mechanical device used to cut plates or bars of metal, wood, or other materials. When cutting plates, a clamping device is generally used to clamp the plate, and then a high-speed rotating saw blade is moved by a feeding device to cut the plate.

[0003] Currently, most circular saws on the market can only make straight cuts in one direction. If the cutting direction needs to be changed, the board needs to be released after one side is cut, and the board's orientation needs to be readjusted so that the side to be cut again is parallel to the saw blade's cutting surface. Then the board needs to be fixed again for cutting, which is quite troublesome. In addition, when cutting boards, it is sometimes necessary to round the corners or edges, but existing circular saws cannot meet the cutting needs well, resulting in a lack of versatility.

[0035] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Reference Figure 1 - Figure 5This application provides a circular saw feeding device, which is applied to a circular saw. The circular saw includes a frame 101, a cutting component 102, and a clamping component 103. The cutting component 102 includes a circular saw blade 1021 and a drive device 1022 for driving the circular saw blade 1021 to rotate at high speed. The feeding device of this application includes a rotating seat 210, and a transverse sliding component 220 is installed on the frame 101. The transverse sliding component 220 can control the rotating seat 210 to slide laterally on the frame 101. Specifically, the transverse sliding component 220 includes two U-shaped plates 221 installed on the frame 101. A transverse guide rail 222 is fixedly connected to the U-shaped plates 221, and a second lead screw 223 is rotatably connected to the U-shaped plates 221. A transverse slide block 224 is slidably connected to the upper part of the U-shaped plate 221. A second lead screw 223 is threadedly connected to the transverse slide block 224. A second motor 225 is installed on one side of the U-shaped plate 221 to drive the second lead screw 223 to rotate. The second motor 225 drives the second lead screw 223 to rotate, and the threaded engagement between the second lead screw 223 and the transverse slide block 224, as well as the sliding engagement between the transverse guide rail 222 and the transverse slide block 224, causes the transverse slide block 224 to slide on the transverse guide rail 222. A longitudinal sliding member 230 is installed on the transverse sliding member 220. The longitudinal sliding member 230 can control the rotating seat 210 to slide longitudinally. Specifically, the longitudinal guide rail 231 includes a longitudinal guide rail 231 fixed between the two transverse slide blocks 224. A longitudinal slide block 232 is slidably connected to the rail 231. A third lead screw 233, threadedly connected to the longitudinal slide block 232, is rotatably connected between two transverse guide rails 222. A third motor 234, which drives the third lead screw 233 to rotate, is mounted on one of the transverse slide blocks 224. The third motor 234 drives the third lead screw 233 to rotate, and the threaded engagement between the third lead screw 233 and the longitudinal slide block 232, as well as the sliding engagement between the longitudinal guide rail 231 and the longitudinal slide block 232, causes the longitudinal slide block 232 to slide on the longitudinal guide rail 231. An angle adjusting component 240 is installed between the longitudinal sliding component 230 and the rotating seat 210. The angle adjusting component 240 controls the rotation of the rotating seat 210. Specifically, the angle adjusting component 240... The frame 101 includes a fourth motor 241 mounted on a longitudinal slide 232 and a mounting plate 242 rotatably connected to the top of the longitudinal slide 232. The fourth motor 241 can drive the mounting plate 242 to rotate, thereby driving the rotating seat 210 fixed to the mounting plate 242 to rotate. A support base 250 is provided above the frame 101, and the cutting piece 102 is rotatably connected to the support base 250. A locking member 260 is also installed on the support base 250. The locking member 260 can be used to lock the cutting piece 102 relative to the support base 250 after the position is adjusted. A diameter-length adjustment member 270 is installed between the support base 250 and the rotating seat 210. The diameter-length adjustment member 270 can be used to adjust the distance between the rotating seat 210 and the support base 250.

[0037] The following section provides a further explanation based on specific application scenarios. When cutting sheet metal, the clamping component 103 is used to horizontally fix the sheet metal onto the frame 101; for example... Figure 1 When the board needs to be cut along the transverse guide rail 222, first adjust the cutting direction of the saw blade 1021 of the cutting part 102. Specifically, rotate the cutting part 102 on the support base 250 so that the saw blade 1021 is parallel to the surface to be cut. Then, use the locking part 260 to lock the cutting part 102 and the support base 250 to ensure that the cutting part 102 will not rotate on the support base 250. Then, move the cutting part 102 to one side of the board along the transverse guide rail 222 and use the third motor 234 to drive the third lead screw 233 to rotate, thereby controlling the longitudinal slide 232 to move along the longitudinal guide rail 231 until the saw blade 1021 coincides with the surface to be cut. Then, use the second motor 225 to drive the second lead screw 223 to rotate, thereby driving the transverse slide 224 to move along the transverse guide rail 222, thereby moving the cutting part 102 along the cutting surface, and thus performing transverse cutting on the board.

[0038] Reference Figure 3 When the board needs to be cut along the longitudinal guide rail 231, first adjust the cutting direction of the saw blade 1021 of the cutting part 102. Specifically, rotate the cutting part 102 on the support seat 250 so that the saw blade 1021 is parallel to the surface to be cut. Then, use the locking part 260 to lock the cutting part 102 and the support seat 250 to ensure that the cutting part 102 will not rotate on the support seat 250. Then, move the cutting part 102 to one side of the board and use the longitudinal sliding part 230 to drive the rotating seat 210 and the cutting part 102 to move together to one side of the board along the longitudinal guide rail 231. Then, use the transverse sliding part 220 to drive the rotating seat 210 and the cutting part 102 to move along the transverse guide rail 222 until the saw blade 1021 coincides with the cutting surface. Then, use the longitudinal sliding part 230 to drive the cutting part 102 to cut the board along the cutting plane.

[0039] It should be noted that when the two sides of the board to be cut are perpendicular to each other, the current circular saw cuts one side, removes the board, adjusts the cut surface, and then fixes the board. However, this application does not require such a complicated process. After one side of the board is cut, the cutting element 102 is rotated around its rotation axis with the support 250, so that the saw blade 1021 of the cutting element 102 changes its orientation. Then, the transverse sliding element 220 and the longitudinal sliding element 230 are used to adjust the cutting element 102 to the initial cutting position of the next cutting surface. The adjustment method is more convenient and labor-saving.

[0040] Reference Figure 4When it is necessary to cut rounded edges or round the corners of a board, first adjust the position of the cutting piece 102 on the support base so that the surface of the saw blade 1021 is perpendicular to the adjustment direction line of the diameter-length adjustment piece 270. This adjustment direction line controls the direction of the support base and the rotating base moving closer or further apart. Then, use the locking piece 260 to fix the cutting piece 102 to the support base 250. Afterwards, adjust the distance between the support base 250 and the rotating base 210 using the diameter-length adjustment piece 270 so that the rotating base 210... The distance between the saw blade 1021 and the saw blade 1021 is exactly equal to the radius of the round edge or round corner to be cut. Then, the position of the rotating seat 210 is adjusted by the transverse sliding member 220 and the longitudinal sliding member 230 so that the position of the rotating seat 210 is exactly at the center of the round edge or round corner to be cut on the board. Finally, the fourth motor 241 drives the mounting plate 242 to rotate, which in turn drives the rotating seat 210, the support seat 250, the diameter and length adjustment member 270, and the cutting member 102 to rotate, thereby realizing the cutting of the round edge or round corner on the board.

[0041] This application, by incorporating a transverse sliding member 220, a longitudinal sliding member 230, an angle adjusting member 240, a diameter-length adjusting member 270, a rotating seat 210, a support seat 250, and a locking member 260, facilitates the adjustment of the cutting direction of the sheet metal. Furthermore, by rotating the cutting member 102 around its axis of rotation with respect to the support seat 250, the saw blade 1021 of the cutting member 102 is made perpendicular to the adjustment direction line of the diameter-length adjusting member 270. Then, the diameter-length adjusting member 270 is used to adjust the relationship between the support seat 250 and the rotating seat 260. The distance between the saw blade 1021 and the axis of the rotating base 210 is such that the radius of the circular edge or rounded corner to be cut on the board is equal to the distance between the axis of the saw blade 1021 and the axis of the rotating base 210. The position of the rotating base 210 is adjusted by the transverse sliding member 220 and the longitudinal sliding member 230 so that the rotating base 210 is located at the center of the circular edge or rounded corner to be cut on the board. Then, the cutting member 102 can be controlled by the angle adjusting member 240 to cut the circular edge or rounded corner of the board. Moreover, this application can cut circular edges or rounded corners of different diameters on the board. Overall, it improves the ease of use and versatility of the circular saw.

[0042] Reference Figure 2 and Figure 5 As a specific embodiment of this application, the diameter-length adjusting member 270 includes a sleeve 271 rotatably connected to the rotating seat 210 and a slide rod 272 slidably connected to the rotating seat 210. A first lead screw 273 is threadedly connected to the sleeve 271. A driving member 274 for driving the sleeve 271 to rotate is installed on the support seat 250. Specifically, the driving member 274 includes a first motor 2741 installed on the support seat 250, a driving gear 2742 fixedly connected to the shaft end of the first motor 2741, and a driven gear 2743 that meshes with the driving gear 2742 fixedly connected to the sleeve 271.

[0043] Depending on the specific application scenario, when it is necessary to adjust the distance between the support base 250 and the rotating base 210, the first motor 2741 is started. The meshing between the drive gear 2742 and the driven gear 2743 drives the sleeve 271 to rotate. The threaded engagement between the sleeve 271 and the first lead screw 273, and the sliding engagement between the slide rod 272 and the rotating base 210, causes the support base 250 and the cutting piece 102 to move closer to or further away from the rotating base 210. This allows for adjustment of the radius of the rounded edge or corner of the material to be cut. Alternatively, an electric telescopic rod can be installed between the support base 250 and the rotating base 210 to control the distance between them.

[0044] Reference Figure 2 and Figure 5 As a specific embodiment of this application, the locking member 260 includes a first annular groove 261 opened on the top of the support base 250, a first locking plate 262 slidably connected in the first groove 261, a connecting plate 263 fixedly connected to the top of the first locking plate 262, and the connecting plate 263 fixedly connected to the cutting member 102. A locking bolt 264 is threadedly connected to the connecting plate 263.

[0045] Furthermore, a second annular slot 265 is provided on the side of the support base 250, and a second card plate 266 is fixedly connected to the connecting plate 263, and the second card plate 266 is slidably disposed in the second slot 265.

[0046] Depending on the specific application scenario, when it is necessary to adjust the orientation of the saw blade 1021 of the cutting component 102, first loosen the locking bolt 264, then control the cutting component 102 to rotate around its axis of rotation with the support base 250 until the orientation of the saw blade 1021 of the cutting component 102 meets the requirements, and then tighten the locking bolt 264 to lock the cutting component 102 and the support base 250. The first clamping plate 262 and the first clamping groove 261, as well as the second clamping plate 266 and the second clamping groove 265, work together to provide auxiliary support and auxiliary rotation between the cutting component 102 and the support base 250 in both vertical and horizontal directions, ensuring the installation stability between the cutting component 102 and the support base 250.

[0047] Furthermore, an adjustment handle 300 is fixedly connected to the connecting plate 263, which allows for convenient adjustment of the orientation of the saw blade 1021 of the cutting piece 102.

[0048] Reference Figure 1 As a specific embodiment of this application, a plurality of hydraulic cylinders 400 are installed between the transverse sliding member 220 and the frame 101, and the hydraulic cylinders 400 are used to control the lifting and lowering of the transverse sliding member 220.

[0049] Depending on the specific application scenario, since the thickness of the boards to be cut may vary, the hydraulic cylinder 400 can be used to drive the entire feed device to lift and lower, thereby adapting to the cutting of boards of different thicknesses, which can further improve the versatility of the circular saw.
