Description

Technical Field

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

[0002] Profiles are materials with specific cross-sectional shapes and dimensions, commonly including aluminum alloys and steel profiles. In practical applications, profiles often need to be processed into components of different lengths to meet specific requirements. Cutting machines, with their high-speed cutting blades, can efficiently cut profiles to meet customized dimensional requirements, making them a commonly used tool in profile processing.

[0003] Most cutting machines typically place the steel pipe on a work plate, with one end in contact with a baffle for support. A clamping mechanism then holds the pipe in place. The cutting blade is then lowered using a handle and brought into contact with the pipe. The friction of the blade cuts the pipe. Since one end of the pipe is in contact with the baffle, the pipe's position determines its length after cutting. The distance from the point of contact between the blade and the pipe to the baffle is the cut pipe length. Cutting different pipe lengths requires either replacing the entire cutting machine, which increases costs, or using tools to loosen the bolts and nuts securing the baffle, repositioning it, and then loosening them again. This process is not only cumbersome but also involves frequent disassembly and reassembly of bolts and nuts, leading to thread wear, reduced lifespan of connecting parts, and impact on equipment stability. Furthermore, it requires significant time for measurement and calibration, severely reducing work efficiency.

[0004] Therefore, it is necessary to provide a new type of profile cutting machine to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 A profile cutting machine includes: a work plate 1, which serves as the basic platform for the entire profile cutting operation, providing a support surface for the installation and operation of other components. An assembly plate 2 is fixedly connected to one side of the top of the work plate 1, further supporting and connecting components, making the overall structure of the cutting machine more rational and orderly. Support plates 3 are symmetrically fixedly connected to the two outer sides of the top of the assembly plate 2. A rotating rod 4 is fixedly connected internally to the adjacent side of the two support plates 3, providing an axis for the rotation of a support plate 5. The support plate 5 is rotatably connected to the outside of the rotating rod 4. The adjacent side of the two support plates 3 is rotatably connected to the front and rear outer sides of the support plate 5. This connection method makes the support plate 5 more stable during rotation. A connecting rod 6 is fixedly connected to the right rear side of the support plate 5, connecting to a transmission rod 7, serving to transmit power and provide support. The transmission rod 7 is rotatably connected to one side of the connecting rod 6. A motor 8 is fixedly connected to the top of the support plate 5, serving as the power source for the entire cutting machine, providing power support for the cutting operation.

[0025] A drive wheel 9 is fixedly connected to the drive end of the motor 8, and a driven wheel 10 is fixedly connected to one end of the transmission rod 7. A pulley 11 is fitted around both the drive wheel 9 and the driven wheel 10. The drive wheel 9 rotates under the drive of the motor 8, which in turn drives the driven wheel 10 to rotate via the pulley 11. This transmission via the pulley 11 ensures smooth power transmission. A cutting blade 12 is fixedly connected to the other end of the transmission rod 7. The cutting blade 12 is the component that directly cuts the profile, using friction to cut the profile during high-speed rotation. A semi-circular protective cover 13 is fixedly connected to one side of the support plate 5, located in the upper half of the cutting blade 12. The semi-circular protective cover 13 effectively prevents debris from flying during the cutting process, protecting the operator's safety. The top of the support plate 5 is fixedly connected to the top of the connecting rod 6 with a push rod 14. The operator controls the rotation of the support plate 5 by operating the push rod 14, thereby controlling the pressing and lifting action of the cutting blade 12. The top of the assembly plate 2 is symmetrically fixedly connected to two guide blocks 15 between the two support plates 3. The guide blocks 15 guide the support plate 5, ensuring that the support plate 5 moves in a predetermined direction during the rotation, pressing and resetting rotation. The bottom end of the support plate 5 contacts the top end of the guide block 15, and the two cooperate with each other during the movement.

[0026] A reset assembly is installed on the top of the working plate 1 near the assembly plate 2. The function of the reset assembly is to ensure that the support plate 5 can smoothly reset after cutting. The reset assembly includes two dampers 16. The top of the dampers 16 is rotatably connected to the bottom of the support plate 5, allowing the dampers 16 to flexibly engage during the movement of the support plate 5. The bottom of the two dampers 16 is fixedly connected to the top of the working plate 1 near the support plate 3, providing stable support. A spring 17 is sleeved on the outside of the dampers 16. The spring 17 is compressed and stores elastic potential energy when the support plate 5 is pressed down. After cutting, the elastic potential energy is released to assist the support plate 5 in resetting. The two ends of the spring 17 are fixedly connected to the working plate 1 and the support plate 5 to ensure the stability of the connection. A cutting hole 18 is provided on the top of the working plate 1 directly below the cutting blade 12. The cutting hole 18 provides space for the downward movement of the cutting blade 12 during cutting and also facilitates the collection of falling cutting debris.

[0027] An adjustment component is installed at the bottom of the baffle 22. This component allows for flexible adjustment of the baffle 22's position to accommodate cutting profiles of different lengths. The adjustment component includes a threaded block 21, the top of which is fixedly connected to the bottom of the baffle 22. The baffle 22 is slidably connected to the right rear side of the top of the working plate 1, and is used to determine the length of the cut profile. A first threaded rod 19 is rotatably connected to the inside of the right rear side of the working plate 1. One end of the first threaded rod 19 is fixedly connected to a first rotating disk 20, which provides a point of leverage for the operator. Rotating the first rotating disk 20 controls the rotation of the first threaded rod 19. A handle is fixedly connected to the side of the first rotating disk 20 away from the first threaded rod 19 and off-axis for easy gripping and force application. The other end of the first threaded rod 19 is threadedly connected to one side of the threaded block 21, allowing for baffle 22 position adjustment via threaded transmission. A pointer 23 is fixedly connected to one side of the baffle 22. A measuring gauge 24 is installed at the top of the work plate 1 directly below the pointer 23. The pointer 23 and the measuring gauge 24 cooperate to indicate the position of the baffle 22, facilitating adjustment by the operator. A sliding hole 25 is provided at the top of the work plate 1 below the baffle 22. The outer side of the threaded block 21 is slidably connected to the inner wall of the sliding hole 25. The sliding hole 25 provides guidance and space for the sliding of the threaded block 21.

[0028] A clamping assembly is installed on the top of the working plate 1 opposite to the baffle 22. This clamping assembly is used to clamp the profile before cutting, preventing movement during the cutting process. The clamping assembly includes a fixing plate 26, the bottom of which is fixedly connected to the front right side of the top of the working plate 1, providing support and connection. A second threaded rod 27 is threaded internally connected to the fixing plate 26. One end of the second threaded rod 27 is fixedly connected to a second rotating disk 28, which provides an operating point for the operator to control the rotation of the second threaded rod 27. A handle is fixedly connected to the side of the second rotating disk 28 away from the second threaded rod 27 and off-axis, facilitating gripping and force application. A pressing plate 29 is rotatably connected to the other end of the second threaded rod 27. Driven by the second threaded rod 27, the pressing plate 29 slides towards the force-bearing plate 30, clamping the profile. The bottom end of the extrusion plate 29 is slidably connected to the top end of the working plate 1 to ensure the stability of the extrusion plate 29 during sliding. A force-bearing plate 30 is fixedly connected to the top end of the working plate 1 opposite to the extrusion plate 29. The force-bearing plate 30 cooperates with the extrusion plate 29 to clamp the profile. Rubber pads are fixedly connected between the extrusion plate 29 and the force-bearing plate 30. The rubber pads increase friction, better fix the profile, and prevent the profile surface from being damaged.

[0029] The working principle of the profile cutting machine provided by this utility model is as follows:

[0030] Step 1: Adjust the position of baffle 22. Adjust the position of baffle 22 according to the required profile length. By rotating the first rotating disk 20, the first rotating disk 20 drives the first threaded rod 19, which is fixedly connected to it, to rotate. Since the threaded block 21 is threadedly connected to the first threaded rod 19, and the top of the threaded block 21 is fixedly connected to the bottom of the baffle 22, the baffle 22 will slide along the sliding hole 25 at the top of the working plate 1 when the first threaded rod 19 rotates. During the adjustment process, observe the corresponding positions of the indicator 23 and the measuring gauge 24 until the baffle 22 is adjusted to the appropriate position, thus determining the desired profile length.

[0031] The second step is to install the profile: Place the profile to be cut on the work plate 1, so that one end of the profile contacts and holds against the baffle 22. At this time, the placement of the profile determines the length of the profile after cutting. The distance from the point where the cutting blade 12 contacts the profile to the baffle 22 is the length after cutting.

[0032] The third step is to clamp the profile: By rotating the handle, the second rotating disk 28 is rotated, which in turn drives the second threaded rod 27 to rotate. Since the second threaded rod 27 is threadedly connected to the fixed plate 26, and the other end of the second threaded rod 27 is rotatably connected to the extrusion plate 29, the extrusion plate 29 will slide towards the force plate 30 at the top of the working plate 1 when the second threaded rod 27 rotates. The rubber pad between the extrusion plate 29 and the force plate 30 is used to firmly clamp the profile, preventing it from moving during the cutting process.

[0033] Then, the motor 8 is started to work, and the drive end of the motor 8 will drive the drive wheel 9 to rotate. The drive wheel 9 drives the driven wheel 10 to rotate through the pulley 11. The driven wheel 10 is fixedly connected to the transmission rod 7, thereby causing the transmission rod 7 to rotate. The cutting blade 12, which is fixedly connected to the other end of the transmission rod 7, also rotates at high speed, ready for cutting.

[0034] The operator then grasps the lever 14 and presses down on the support plate 5. The support plate 5 rotates around the rotating rod 4, at which point the bottom end of the support plate 5 contacts the top end of the guide block 15 and slides along the guide block 15, serving a guiding function. As the support plate 5 rotates and presses down, the cutting blade 12 connected to the support plate 5 gradually approaches and contacts the profile. Simultaneously, the damper 16 is compressed, and the spring 17 is also compressed to store elastic potential energy. The cutting blade 12 uses the friction generated by its high-speed rotation to cut the profile.

[0035] After the profile is cut, the operator holds the lever 14 and slowly releases the force. Then, with the help of the damper 16 and the spring 17, the bearing plate 5 rotates upward to reset, and the cutting blade 12 moves away from the surface of the working plate 1 and returns to its initial position.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
