Description

Technical Field

[0001] The utility model relates to a cutting machine, more specifically, it relates to a transmission type cutting machine. Background Art

[0002] The hand pressure cutter is a device that drives the cutting blade to work by manually operating the pressure handle. It has the characteristics of simple operation, high flexibility and wide application range. It is suitable for home, small waterproof engineering site and other occasions, and can cut a variety of materials such as wood, steel bars, steel pipes, etc. When using, it is necessary to ensure that the cutting bed is stable, select the appropriate cutting head, and apply force evenly to avoid material damage. After operation, clean and maintain the equipment in time to ensure safety and work efficiency. The hand pressure cutter provides an effective solution for fast and convenient cutting needs. The existing hand pressure cutter drive motor directly drives the saw blade to rotate, and the pressure handle is moved down to complete the cutting. After cutting, the cutter needs to be lifted and reset. The lifted cutter is generally kept in its lifted state by the reset spring. When the reset spring is damaged due to rust, the cutter cannot be lifted by itself, and the pressing action of the cutter and the motor starting action are often linked. The cutter cannot keep the lifted state by itself, and it is easy to cause safety accidents after starting the motor during the self-pressing process. Utility Model Content

[0027] Example:

[0028] A transmission type cutting machine comprises a base 1, a bracket 2 and a cutting device; the bracket 2 is arranged on the base 1; the cutting device comprises a mounting mechanism 4, a driving mechanism 3 and a cutting mechanism 5. The driving mechanism 3 works with the driving cutting mechanism 5, and the mounting mechanism 4 is used to fix the driving structure and the cutting mechanism 5. The mounting mechanism 4 is rotatably connected to the bracket 2; the driving mechanism 3 is arranged at both ends of the mounting mechanism 4 to form a seesaw-like structure. The torque at one end of the driving mechanism 3 is greater than the torque at one end of the cutting mechanism 5, so that in the absence of external force, one end of the driving mechanism 3 can tilt one end of the cutting mechanism 5 upward.

[0029] In a preferred embodiment based on the above embodiment, the bracket 2 includes a first bracket and a second bracket. The mounting mechanism 4 includes a support block 41, a mounting plate 42 and a transmission shaft cylinder 43; the support block 41 is rotatably connected to the bracket 2 through a bracket shaft; the mounting plate 42 is fixedly connected to the support block 41. By providing the first bracket and the second bracket, the cutting device can be more stably mounted on the base 1 through the bracket 2.

[0030] In a preferred embodiment based on the above embodiment, the mounting plate 42 is further provided with a first mounting hole and a second mounting hole; the second mounting hole is coaxially arranged with the transmission shaft tube 43; the first mounting hole and the second mounting hole are respectively located on both sides of the connection between the support block 41 and the mounting plate 42. The driving mechanism 3 includes a motor 31, a first bearing and a first synchronous pulley 32; the first bearing is arranged in the first mounting hole; the motor 31 is connected to the mounting plate 42; the motor shaft passes through the first bearing and is connected to the first synchronous pulley 32; the motor shaft is fixedly connected to the inner ring of the first bearing. The first synchronous pulley 32 and the motor 31 body are respectively located on both sides of the first bearing; after the first bearing is fixedly connected to the mounting plate 42, the rotation of the motor 31 is more stable due to the restriction of the first bearing. The cutting mechanism 5 includes a saw blade 51, a second bearing, a third bearing and a second synchronous pulley 53; the second bearing is arranged in the second mounting hole; the third bearing is arranged in the transmission shaft cylinder 43; the second bearing and the third bearing are respectively located at both ends of the transmission shaft cylinder 43; the transmission shaft connects the second bearing and the third bearing; the second synchronous pulley 53 and the saw blade 51 are respectively arranged at both ends of the transmission shaft; the first synchronous pulley 32 and the second synchronous pulley 53 are connected by the synchronous belt 6. By arranging the second bearing and the third bearing, the transmission shaft can rotate more smoothly.

[0031] Through the above-mentioned embodiment, the cutting device is rotatably connected to the bracket 2; the cutting mechanism 5 and the driving mechanism 3 are located at both ends of the rotation point, forming a seesaw-like structure. When cutting, the cutting mechanism 5 is pressed to complete the cutting; after the cutting is completed, since the motor 31 is heavy, the torque on one side of the driving mechanism 3 is greater than the torque on one side of the cutting mechanism 5, and the cutting mechanism 5 is tilted by the gravity of the motor 31 to ensure that the cutting mechanism 5 is in a lifted state. In the absence of artificial external force, the saw blade 51 is always in a lifted state. The problem in the prior art that the saw blade 51 needs a reset spring to maintain the lifted state is solved, thereby increasing the safety of the cutting machine.

[0032] In a preferred embodiment based on the above embodiment, a dust cover 61 is further provided on the mounting plate 42. The installation of the dust cover 61 effectively isolates the debris in the cutting process, protects the first synchronous pulley 32, the second synchronous pulley 53 and the synchronous belt 6, prolongs the life of the equipment, improves the product quality, simplifies the maintenance and cleaning process, and provides a stable and reliable guarantee for production and manufacturing. Preferably, the dust cover is detachably connected to the mounting plate. Optionally, the dust cover is connected to the mounting plate by screws.

[0033] In a preferred embodiment based on the above embodiment, a handle 54 is provided on the transmission shaft cylinder 43. The handle 54 prolongs the torque, so that the user can save more effort during operation. This design allows the user to use the lever principle to generate a larger torque with a smaller force when rotating the transmission shaft cylinder 43, thereby completing the operation more easily. This not only improves the convenience and efficiency of the operation, but also reduces the labor intensity of the user, making the entire operation process more comfortable and easy.

[0034] In a preferred embodiment based on the above embodiment, a saw blade cover is further provided on the transmission shaft cylinder 43; the saw blade 51 is provided in the saw blade cover. The saw blade cover can effectively prevent the debris generated during the cutting process from splashing out, avoiding the risk of injury to the user, thereby greatly improving the safety of the workplace. At the same time, the saw blade cover also protects the saw blade 51 itself, reduces the possibility of the saw blade 51 being damaged by the collision of debris, and prolongs the service life of the saw blade 51. The implementation of this technical solution not only ensures the personal safety of the user, but also improves the overall performance and reliability of the equipment.

[0035] In a preferred embodiment based on the above embodiment, a saw blade groove 11 is provided on the base 1 .

[0036] In a preferred embodiment based on the above embodiment, a steel bar fixing mechanism is provided on the base 1; the steel bar fixing mechanism includes a fixing part 71 and a movable part 72; the fixing part 71 includes a first fixing plate 711 and an adjusting plate 712; the first fixing plate 711 and the adjusting plate 712 are vertically connected to each other; the adjusting plate 712 is connected to the base 1 through a fixing shaft 713; with the fixing shaft 713 as the center of the circle, an arc-shaped adjusting groove 714 is also provided on the adjusting plate 712; a fixing bolt is provided in the adjusting groove 714. Loosening the fixing screw, the adjusting plate 712 can drive the first fixing plate 711 to rotate along the fixing shaft 713, so that the first fixing plate 711 faces different angles. When cutting steel bars or steel pipes, the steel bars or steel pipes can be placed against the first fixing plate 711 to cut a suitable angle. The use of the first fixing plate 711 can ensure that the angles of the steel bars, steel pipes and other materials cut in the same batch are the same. Preferably, an angle scale is provided on the adjustment, so that the angle can be adjusted more conveniently.

[0037] In a preferred embodiment based on the above embodiment, the movable component 72 includes a screw sleeve 721 and a screw 722; the screw sleeve 721 is arranged on the base 1; the screw 722 is arranged in the screw sleeve 721; a second fixing plate 723 is arranged on the screw 722; the second fixing plate 723 is hinged to the screw 722. The second fixing plate 723 is close to the first fixing plate 711 through the screw 722, which can better fix the cutting material, and because the second fixing plate 723 is hinged to the screw 722, it can better cooperate with the first fixing plate 711 to cut a suitable angle.

[0038] In a preferred embodiment based on the above embodiment, a rotating disk 724 is further provided on the screw rod 722. The rotating disk 724 can be used to conveniently adjust the extended length of the screw rod 722.

[0040] Main advantages of technical solutions:

[0041] Efficient and labor-saving: Through the seesaw structure design, the motor gravity is used to automatically lift the saw blade, without the need for a return spring, making the operation more labor-saving, improving work efficiency and increasing safety.

[0042] Firm and stable fixation: The steel bar fixing mechanism adopts a combination design of fixed parts and movable parts. Through the cooperation of the adjustment plate and the screw rod, it can firmly fix materials such as steel bars or steel pipes to ensure that there will be no displacement or shaking during the cutting process, thereby ensuring the accuracy and stability of the cutting.

[0043] Strong adaptability: The steel bar fixing mechanism is highly flexible. By adjusting the rotation of the plate and the extension of the screw rod, it can adapt to the fixing needs of steel bars or steel pipes of different sizes, shapes and angles. This adaptability enables the mechanism to play a good fixing role in a variety of scenarios.

[0044] Improve cutting accuracy: The steel bar fixing mechanism can ensure that the steel bar or steel pipe maintains a stable posture during cutting, avoiding cutting deviation caused by material shaking. This greatly improves the cutting accuracy and makes the cut material more in line with the design requirements.
