Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a cutting machine with a rotatable cutting angle. Background Technology

[0002] There are various methods for cutting steel, including flame cutting, plasma cutting, laser cutting, and abrasive wheel cutting. Among these, abrasive wheel cutting is widely used in some small and medium-sized processing scenarios due to its low equipment cost and relatively simple operation. It mainly utilizes the friction and grinding action generated when a high-speed rotating abrasive wheel comes into contact with the steel to achieve cutting. However, abrasive wheel cutting has significant drawbacks.

[0003] Existing steel pipe cutting equipment (such as portable pipe cutters and stationary pipe cutters) can typically only perform vertical cuts. For situations requiring cuts at arbitrary angles (such as pipe intersections or connections of irregular structures), it is difficult to accurately and conveniently set the angle. In such cases, a common cutting method is to rotate the steel to achieve the desired cutting angle. This method has low cutting efficiency; furthermore, because the steel's position changes after rotation, general-purpose clamping devices cannot effectively hold the steel in place, potentially leading to deviations in the cutting process and a decrease in cutting quality, making it difficult to meet diverse processing needs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a cutting machine with a rotatable cutting angle, which solves the problem that the existing cutting machine is difficult to cut because the angle cannot be adjusted.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cutting machine with a rotatable cutting angle includes a cutting table, a horizontal rotating base movably connected to the cutting table, a vertical rotating component mounted on the horizontal rotating base, and a cutting mechanism mounted on the top of the vertical rotating component; a clamping device is also provided on the cutting table, and the object to be cut is fixed on the clamping device.

[0006] In this design, the cutting mechanism is first raised by a vertical rotating component, and then rotated to the side by a horizontal rotating base. The steel to be cut is fixed on the clamping component, and the cutting mechanism is rotated to be directly above the steel. The angle of the cutting mechanism is adjusted during rotation. Finally, the cutting mechanism is lowered to perform the cutting. The angle of the cutting mechanism is flexibly adjustable, the operation is simple, and it can accurately complete any bevel cutting.

[0007] Furthermore, the horizontal rotating base includes a fixed base and a horizontal turntable, with the fixed base fixed to the cutting table; a rotating ring extends downward from the bottom of the horizontal turntable and is rotatably connected to the fixed base; and a vertical rotating assembly is disposed on the horizontal turntable.

[0008] In this design, the horizontal turntable can rotate relative to the fixed base, and the rotation drives the cutting mechanism to adjust the cutting angle.

[0009] Furthermore, a U-shaped frame is also provided on the horizontal turntable, and a manual adjustment rod is movably connected to the U-shaped frame. A limit rod is connected to the bottom of the manual adjustment rod. The cutting table has several angle adjustment holes, which are distributed along the path swept by the limit rod when the horizontal turntable rotates; the bottom of the limit rod is embedded in the angle adjustment hole to fix the horizontal turntable.

[0010] In this solution, when rotating the horizontal turntable, first lift the end of the manual adjustment rod away from the U-shaped frame, so that the manual adjustment rod rotates relative to the U-shaped frame until the limit rod is pulled out from the angle adjustment hole; then drive the horizontal turntable to rotate through the manual adjustment rod. When the horizontal turntable rotates to the appropriate angle, lower the manual adjustment rod so that the limit rod is re-engaged into the angle adjustment hole, and the horizontal turntable is fixed, thus preventing the cutting mechanism from rotating during the cutting process and affecting the cutting accuracy.

[0011] Furthermore, the vertical rotating assembly includes two parallel mounting plates, the bottoms of which are fixedly connected to a horizontal turntable; a vertical turntable is movably connected between the two mounting plates. The vertical turntable includes two arc-shaped fan-shaped wheels, which are connected by a connecting plate. Sliding edges are provided on the arc edges of both fan-shaped wheels. Three pulleys are arranged in a triangular pattern on the opposite sides of the two mounting plates. One pulley is slidably connected to the top of the sliding edge, and the other two pulleys are slidably connected to the bottom of the sliding edge. A mounting bracket is fixed in the middle of the horizontal turntable. The fixed end of the hydraulic cylinder is hinged to the mounting bracket, and the movable end of the hydraulic cylinder is rotatably connected to the outward-extending support arm on the connecting plate.

[0012] In this design, the hydraulic cylinder extends and retracts, driving the vertical turntable to move. The sliding edge of the sector-shaped wheel on the turntable slides between three pulleys, which limit the movement of the sector-shaped wheel. When the hydraulic cylinder extends, it pushes the end of the vertical turntable with the support arm upwards, causing the cutting mechanism to move downwards for cutting. When the hydraulic cylinder retracts, it pulls the end of the vertical turntable with the support arm downwards, causing the cutting mechanism to lift upwards. The height adjustment of the cutting mechanism is achieved entirely through the hydraulic cylinder, making operation simple and labor-saving.

[0013] Furthermore, the cutting mechanism includes a motor mounting bracket, which is mounted on the top of the vertical turntable; a drive motor is mounted on the motor mounting bracket, and a drive gear is fixed on the output shaft of the drive motor, which meshes with a driven gear on the rotating shaft for transmission; the rotating shaft is movably connected to the motor mounting bracket, and one end of the rotating shaft extends out of the motor mounting bracket and is connected to the cutting blade.

[0014] In this solution, the drive motor drives the rotating shaft to rotate through the transmission action of the drive gear and the driven gear, which in turn drives the cutting blade to rotate, thereby achieving cutting.

[0015] Furthermore, a protective cover is also provided on the top of the cutting blade.

[0016] In this design, the protective shield prevents debris generated during cutting from flying everywhere.

[0017] Furthermore, the clamping device includes a worktable with several parallel grooves; each groove contains a slider with a slotted hole on its side and a locking screw fixed inside the slotted hole; a clamping block is connected to the top of the slider.

[0018] In this solution, the steel is placed on the workbench, and several clamping blocks are slid to both sides of the steel to clamp it. After clamping, locking screws are used to lock the steel to prevent it from moving during the cutting process.

[0019] Furthermore, several cutting grooves are also provided on the workbench.

[0020] In this design, during the cutting process, the bottom of the cutting blade is located inside the cutting groove.

[0021] The beneficial effects of this utility model are: In this utility model of a cutting machine with a rotatable cutting angle, a horizontal turntable is rotatably connected to a fixed base. Before cutting, the horizontal turntable is rotated to adjust the cutting angle of the cutting blade. After the angle is adjusted, a hydraulic cylinder drives the vertical turntable to move, which in turn moves the cutting blade downward to achieve cutting. The cutting angle is easy to adjust, and it can achieve multi-angle cutting at intervals of 11.25°. It can meet the angle adjustment within the range of 0-45°, meet the angle requirements for bevel cutting, and solve the problem of fixed angle when cutting steel.

[0022] When rotating the horizontal turntable, the manual adjustment lever drives the turntable to rotate. Once the turntable reaches the appropriate angle, the manual adjustment lever is lowered, causing the limit rod to engage with the angle adjustment hole, thus fixing the turntable and preventing rotation of the cutting mechanism during the cutting process. To control the raising and lowering of the cutting blade, a hydraulic cylinder is used because the drive motor is relatively heavy, making operation simple and labor-saving.

The specific embodiments of the present invention are described below to facilitate understanding by those skilled in the art. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0025] like Figures 1-5 As shown, this embodiment provides a cutting machine with a rotatable cutting angle. This cutting machine has a simple structure, low cost, and facilitates cutting steel pipes at different angles; specifically, it includes: 1. Cutting table; 2. Horizontal rotating base; 3. Vertical rotating assembly; 4. Cutting mechanism; 5. Clamping device; The cutting table 1 is movably connected to a horizontal rotating base 2, and a vertical rotating component 3 is provided on the horizontal rotating base 2. A cutting mechanism 4 is installed on the top of the vertical rotating component 3. The cutting table 1 is also provided with a clamping device 5, and the object to be cut is fixed on the clamping device 5.

[0026] The horizontal rotating base 2 includes a fixed base 21 and a horizontal turntable 22. The fixed base 21 is fixed on the cutting table 1. The bottom of the horizontal turntable 22 extends downward into a rotating ring, which is rotatably connected to the fixed base 21. The horizontal turntable 22 can rotate relative to the fixed base 21, and during the rotation, it drives the cutting mechanism 4 to adjust the cutting angle.

[0027] A U-shaped frame is also provided on the horizontal turntable 22, and a manual adjustment rod 23 is movably connected to the U-shaped frame. The bottom of the manual adjustment rod 23 is connected to a limit rod 24. Several angle adjustment holes 25 are provided on the cutting table 1, and these holes 25 are distributed along the path swept by the limit rod 24 when the horizontal turntable 22 rotates. The bottom of the limit rod 24 is embedded in the angle adjustment hole 25 to fix the horizontal turntable 22. When the horizontal turntable 22 rotates, the end of the manual adjustment rod 23 away from the U-shaped frame is first lifted, so that the manual adjustment rod 23 rotates relative to the U-shaped frame until the limit rod 24 is pulled out of the angle adjustment hole 25. Then, the horizontal turntable 22 is rotated by the manual adjustment rod 23. When the horizontal turntable 22 rotates to the appropriate angle, the manual adjustment rod 23 is lowered, so that the limit rod 24 is re-engaged into the angle adjustment hole 25, and the horizontal turntable 22 is fixed, preventing the cutting mechanism 4 from rotating during the cutting process and affecting the cutting accuracy.

[0028] As a preferred embodiment, the interval between two adjacent angle adjustment holes 25 is 11.25°.

[0029] The vertical rotating assembly 3 includes two parallel mounting plates 31, the bottoms of which are fixedly connected to the horizontal turntable 22; a vertical turntable 32 is movably connected between the two mounting plates 31.

[0030] like Figure 4 As shown, the vertical turntable 32 includes two arc-shaped fan-shaped wheels 321, which are connected by a connecting plate 323. Each of the arc-shaped wheels 321 has a sliding edge 322. Each of the two mounting plates 31 has three pulleys 324 arranged in a triangle on their opposite sides. One pulley 324 is slidably connected to the top of the sliding edge 322, and the other two pulleys 324 are slidably connected to the bottom of the sliding edge 322.

[0031] A mounting bracket 33 is fixed in the middle of the horizontal turntable 22. The fixed end of the hydraulic cylinder 34 is hinged to the mounting bracket 33, and the movable end of the hydraulic cylinder 34 is rotatably connected to the outwardly extending support arm 325 on the connecting plate 323. When the hydraulic cylinder 34 extends or retracts, it drives the vertical turntable 32 to move. The sliding edge 322 of the sector wheel 321 in the vertical turntable 32 slides between the three pulleys 324, and the pulleys 324 limit the movement of the sector wheel 321. When the hydraulic cylinder 34 extends, it pushes the end of the vertical turntable 32 with the support arm 325 to move upward, at which time the cutting mechanism 4 moves downward to perform cutting. When the hydraulic cylinder 34 retracts, it pulls the end of the vertical turntable 32 with the support arm 325 to move downward, at which time the cutting mechanism 4 is lifted upward. The height adjustment of the cutting mechanism 4 is achieved entirely through the hydraulic cylinder 34, which is simple and labor-saving to operate.

[0032] like Figure 3 As shown, the cutting mechanism 4 includes a motor mounting bracket 41, which is mounted on the top of the vertical turntable 32. A drive motor 42 is mounted on the motor mounting bracket 41, and a drive gear 43 is fixed on the output shaft of the drive motor 42. The drive gear 43 meshes with a driven gear 44 on a rotating shaft 45. The rotating shaft 45 is movably connected to the motor mounting bracket 41, and one end of the rotating shaft 45 extends out of the motor mounting bracket 41 and connects to the cutting blade 46. The drive motor 42 drives the rotating shaft 45 to rotate through the transmission action of the drive gear 43 and the driven gear 44, thereby driving the cutting blade 46 to rotate and achieve cutting.

[0033] The top of the cutting blade 46 is also provided with a protective cover 47, which can prevent the debris generated during cutting from flying.

[0034] The clamping device 5 includes a worktable 51, a slider 52, and clamping blocks 53. The worktable 51 has several parallel grooves; each groove contains a slider 52, and each slider 52 has a slotted hole on its side, into which a locking screw is fixed. The top of the slider 52 is connected to the clamping block 53. The steel is placed on the worktable 51, and the clamping blocks 53 are slid to both sides of the steel to clamp it. After clamping, the locking screws are used to lock the clamping mechanism to prevent the steel from moving during cutting.

[0035] The workbench 51 is also provided with several cutting grooves 54, and the bottom of the cutting blade 46 is located in the cutting grooves 54 during the cutting process.

[0036] The working principle of this embodiment is as follows: Before cutting, adjust the angle of the cutting blade 46. To adjust, first lift the end of the manual adjustment rod 23 away from the U-shaped frame, so that the manual adjustment rod 23 rotates relative to the U-shaped frame until the limiting rod 24 is pulled out of the angle adjustment hole 25; then, drive the horizontal turntable 22 to rotate through the manual adjustment rod 23. When the horizontal turntable 22 rotates to the appropriate angle, lower the manual adjustment rod 23 so that the limiting rod 24 re-engages into the angle adjustment hole 25, and the horizontal turntable 22 is fixed.

[0037] After adjusting the angle, the hydraulic cylinder 34 drives the cutting blade 46 to descend. The hydraulic cylinder 34 extends, pushing the end of the vertical turntable 32 with the support arm 325 upward. At this time, the end with the cutting blade 46 moves downward, and the cutting blade 46 contacts the steel on the worktable 51 to cut it.

[0038] Those skilled in the art will recognize that the embodiments described herein are intended to help the reader understand the principles of this invention, and should be understood that the scope of protection of this invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on these technical teachings disclosed in this invention without departing from the essence of this invention, and these modifications and combinations are still within the scope of protection of this invention.
