Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, and particularly relates to a high-speed rotary cutting machine. Background Art

[0002] Rotary cutting machines are widely used in the processing fields of materials such as bars, pipes, and profiles. Common rotary cutting machines usually include a rotary cutting tool mechanism that makes a rotary cutting motion during work and a workpiece clamping mechanism for fixing the workpiece for cutting. For example, a plastic pipe rotary cutting device disclosed in a patent document with the authorization publication number CN202622857 and a high-speed automatic rotary cutting equipment for stainless steel pipes disclosed in a patent document with the application publication number CN114789356 are both rotary cutting equipment adopting the above-mentioned structure. The common deficiency of such rotary cutting equipment with workpiece fixation and cutter rotary cutting is that for workpieces with a relatively large outer diameter size to be cut, the diameter of the cutting tool of the existing such rotary cutting equipment must be relatively large. Correspondingly, the electric power consumption for driving the large-size cutting tool to rotate is also relatively large, and the cutting time is also relatively long, presenting an overall situation of high power consumption and low efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-speed rotary cutting machine that can significantly improve the cutting efficiency and significantly reduce the power consumption to solve the problems existing in the prior art.

[0004] The technical solution of the utility model is as follows: The high-speed rotary cutting machine of the utility model includes a frame as the installation basis, and its structural feature is that it further includes a feed driving mechanism arranged on the above-mentioned frame for driving the workpiece to be cut to move in the cutting direction, a rear chuck arranged on the feed driving mechanism for clamping the end of the workpiece to be cut, pushing the workpiece to move forward, and driving the workpiece to rotate during cutting, a front chuck arranged on the frame for clamping the front part of the workpiece to be cut and synchronously driving the workpiece to rotate with the rear chuck during cutting, and a rotary cutting tool mechanism arranged on the frame and located on the front side of the front chuck for performing rotary cutting on the workpiece to be cut.

[0005] A further solution is as follows: The above-mentioned feed driving mechanism includes two guide rails fixedly arranged on the frame, 1 - 3 sliders slidably arranged on each of the two guide rails, a rack fixedly arranged on the frame, a mounting seat fixedly connected to each slider, a feed driving motor fixedly arranged on the mounting seat, and a feed gear drivingly connected to the feed driving motor and meshing with the rack.

[0006] A further solution is as follows: The above-mentioned feed driving mechanism further includes a feed proximity switch for preventing collision, the above-mentioned guide rails are linear guide rails; the above-mentioned rear chuck is fixedly arranged on the mounting seat of the feed driving mechanism.

[0007] A further solution is as follows: The above-mentioned rotary cutting tool mechanism includes a base fixedly connected to the frame, a saw blade rotatably arranged on the base, a saw blade rotation driving motor arranged on the base for driving the saw blade to rotate, and a saw blade feeding driving motor for pushing the saw blade to feed during cutting.

[0008] A further solution is as follows: The saw blade of the above-mentioned rotary cutting tool mechanism is a circular saw blade.

[0009] The utility model has positive effects: (1) Through the design of the overall structure of the utility model, during the working process, while the saw blade rotates, the workpiece to be cut is clamped and rotated simultaneously by the front chuck and the rear chuck, that is, two coordinated rotations are used to cut the workpiece to be cut. Compared with the prior art in which only the saw blade rotates in the same type of rotary cutting device, the processing efficiency can be increased by more than 10 times; at the same time, since cutting a large-diameter pipe only requires cutting through its wall thickness or cutting a large-diameter solid rod only requires cutting to half of its diameter, while in the prior art, to cut a pipe or rod of the same diameter, the diameter of the saw blade needs to be the same as the material diameter. Therefore, when the utility model cuts a large-diameter pipe or rod, the size of its saw blade only needs to be half of that in the prior art, or in other words, for a saw blade of the same size, the workpiece size that can be processed by the high-speed rotary cutting machine of this embodiment is twice that of the prior art; and the energy consumption of the motor driving the saw blade during the processing is reduced by at least more than half. (2) By setting the feeding driving mechanism, the rear chuck and the front chuck, during the cutting process, through the cooperation of the three, the workpiece to be cut can be automatically fed to cut out finished workpieces one by one, saving manpower and improving work efficiency. (3) By setting proximity switches, it can effectively prevent collisions during the working process and ensure operation safety. Brief Description of the Drawings

[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] (Embodiment 1)

[0023] See Figures 1 to 5 , the high-speed rotary cutting machine of this embodiment mainly consists of a frame 1, a feed driving mechanism 2, a rear chuck 3, a front chuck 4 and a rotary cutting tool mechanism 5.

[0024] The frame 1 serves as the installation basis for other mechanisms of the high-speed rotary cutting machine of this embodiment.

[0025] The feed driving mechanism 2 is used to drive the workpiece to be cut forward during operation, that is, in the cutting direction. As a specific implementation, in this embodiment, the feed driving mechanism 2 mainly consists of two guide rails 21 fixedly arranged on the frame 1, one to three sliders 22 slidably arranged on each of the two guide rails 21, a rack 23 fixedly arranged on the frame 1, a mounting seat 24 fixedly connected to each slider 22, a feed driving motor 25 fixedly arranged on the mounting seat 24, and a feed gear 26 drivingly connected to the feed driving motor 25 and meshing with the rack 23. During operation, the feed driving motor 25 drives the feed gear 26 to rotate, and through the meshing of the feed gear 26 and the feed rack 23, the mounting seat 24 slides on the guide rail 21 relying on each slider 22. The aforementioned guide rail 21 is a linear guide rail. As a preferred mode, the feed driving mechanism 2 further includes a feed proximity switch 27 for preventing collisions to ensure safety.

[0026] The rear chuck 3 is fixedly arranged on the mounting base 24 of the feed driving mechanism 2, and is used to clamp the end of the workpiece to be cut during use to push the workpiece to be cut forward and drive the workpiece to be cut to rotate during cutting; the rear chuck 3 can adopt a chuck with a rotation function in the prior art, such as the chuck disclosed in the authorized publication number CN214684319U. The rear chuck 3 has jaws 31 (also called clamping jaws) for clamping the end of the workpiece to be cut. The rear chuck 3 is equipped with a rear chuck rotation driving motor 32 to drive the jaws 31 to rotate so as to rotate the workpiece to be cut. During operation, the rear chuck 3 can move along with the mounting base 24. The specific structure of the rear chuck 3 is the prior art and will not be elaborated.

[0027] The front chuck 4 is fixedly arranged on the machine frame 1, and is used to clamp the front part of the workpiece to be cut during use and drive the workpiece to be cut to rotate synchronously with the rear chuck 3 during cutting; the front chuck 4 can adopt a hollow chuck with a rotation function and a central through hole in the prior art, such as the chuck disclosed in the publication number CN115446473A. The front chuck 4 has jaws 41 (also called chucks) for clamping the front part of the workpiece to be cut. The front chuck 4 is equipped with a front chuck rotation driving motor 42 to drive the jaws 41 to rotate so as to rotate the workpiece to be cut. The specific structure of the front chuck 4 is the prior art and will not be elaborated.

[0028] The rotary cutting tool mechanism 5 is fixedly arranged adjacent to the front chuck 4 on the machine frame 1 and is located on the front side of the front chuck 4. The rotary cutting tool mechanism 5 is used to cut the workpiece to be cut during use. The rotary cutting tool mechanism 5 is a commercially available kit, which includes a base 51 fixedly connected to the machine frame 1, a circular saw blade 52 rotatably arranged on the base 51, a saw blade rotation driving motor 53 arranged on the base 51 for driving the saw blade 52 to rotate, and a saw blade feed driving motor 54 for pushing the saw blade 52 to feed during cutting. The specific structure and working principle of the rotary cutting tool mechanism 5 are the prior art and will not be elaborated. During operation, the saw blade 52 of the rotary cutting tool mechanism 5 rotates, and at the same time, the rear chuck 3 and the front chuck 4 clamp the workpiece to be cut and rotate to perform rotary cutting on the workpiece to be cut. The rotation direction of the saw blade 52 and the rotation direction of the workpiece 100 can be the same or opposite; preferably, the rotation directions of the two are the same to achieve the best technical effect.

[0029] It should be particularly noted that when the high-speed rotary cutting machine of this embodiment is in use, its various motors, chucks, proximity switches, etc. are all electrically connected to the main control device on the cutting processing production line and are controlled by the main control device. All of these are mature prior arts and will not be elaborated.

[0030] The working principle and process of the high-speed rotary cutting machine of this embodiment are briefly described as follows:

[0031] During operation, the workpiece to be cut is placed between the rear chuck 3 and the front chuck 4 by the equipment supporting the cutting production line. After the rear chuck 3 clamps the end of the workpiece to be cut using the chuck jaw 31, driven by the feed driving mechanism 2, it pushes the workpiece to be cut forward so that the front end of the workpiece to be cut passes through the central hole of the front chuck 4 and reaches the set length. The chuck jaw 41 of the front chuck 4 clamps the workpiece to be cut. The rear chuck rotation driving motor 32 of the rear chuck 3 and the front chuck rotation driving motor 42 of the front chuck 4 are started to drive the workpiece to be cut to rotate. At the same time, the saw blade rotation driving motor 53 of the rotary cutting tool mechanism 5 drives the saw blade 52 to rotate, and the saw blade feed driving motor 54 drives the saw blade 52 to move towards the workpiece to be cut for rotary sawing. In the state where the saw blade 52 rotates and the workpiece to be cut rotates simultaneously, finished workpieces can be quickly sawn. After a finished workpiece is completed, the rear chuck 3 and the front chuck 4 stop rotating. The saw blade feed driving motor 54 of the rotary cutting tool mechanism 5 drives the saw blade 52 to reset. The front chuck 4 releases the workpiece to be cut. The rear chuck 3 continues to translate forward to the designated position according to the set length. The front chuck 4 clamps the workpiece, and the foregoing actions are repeated to cut out the second finished workpiece. This is repeated until the first workpiece to be cut 1 is completely processed, and then the foregoing actions are repeated again.

[0032] As can be seen from the foregoing, the high-speed rotary cutting machine of this embodiment is different from the rotary cutting devices in the prior art. During operation, while the saw blade 52 rotates, the workpiece to be cut also rotates simultaneously under the synchronous drive of the rear chuck 3 and the front chuck 4. Compared with the prior art method where only the saw blade rotates during cutting, the processing efficiency can be increased by more than 10 times. At the same time, since cutting large-diameter pipe materials only requires cutting through their wall thickness, or cutting large-diameter solid rod materials only requires cutting to half of their diameter, while in the prior art, to cut pipe materials or rod materials of the same diameter, the diameter of the saw blade needs to be the same as the material diameter. Therefore, when the high-speed rotary cutting machine of this embodiment cuts large-diameter pipe or rod workpieces, the size of its saw blade only needs to be half of that in the prior art. In other words, for the same size saw blade, the workpiece size that can be processed by the high-speed rotary cutting machine of this embodiment is twice that of the prior art. And during the processing, the energy consumption of the motor driving the saw blade movement is at least reduced by more than half.

[0033] The above embodiments are descriptions of the specific implementation manners of the present invention, rather than limitations on the present invention. Those skilled in the relevant technical fields can also make various transformations and changes to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
