Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a high-speed metal circular saw machine. Background Art

[0002] High-speed metal circular saws are mainly used to cut various metal materials, such as steel, iron, aluminum, copper, etc. The rotating blade can quickly and accurately cut materials of the required shape and size. This equipment is widely used in metal processing, machinery manufacturing, aerospace and other fields.

[0003] The fully automatic high-speed metal circular saw mechanism disclosed in the patent application with reference publication number CN219986405U moves toward the direction of the steel pipe through the cutting mechanism, and drives the limiting mechanism to move together. During the movement, the pressure block on the limiting mechanism first contacts the steel pipe, and under the abutting force of the constant pressure unit, the pressure block limits and presses the steel pipe, and then the cutting mechanism cuts the steel pipe. After the processing is completed, the cutting mechanism drives the limiting mechanism away from the steel pipe, so that the pressure block on the limiting mechanism is separated from the steel pipe, thereby releasing the limit on the steel pipe, thereby achieving the effect of automatically clamping and fixing the steel pipe before cutting, and releasing the clamping after cutting.

[0004] When the existing high-speed metal circular saw machine is cutting, it is necessary to use a clamping tool to fix the position of the metal bar or metal pipe, and the clamping tool mostly clamps the metal bar or metal pipe by clamping on both sides. Since the outer wall of the metal bar or metal pipe is not a standard plane, and its surface is an arc-shaped structure, the traditional clamping tool can only clamp the outer wall of the metal bar or metal pipe at two points, resulting in poor clamping stability, making it difficult to make the clamping part of the clamping tool and the outer wall of the metal bar or metal pipe in close contact, and the metal bar or metal pipe is easily deformed and damaged due to excessive concentration of clamping force during the clamping process;

[0005] Moreover, during the stacking process of metal bars or metal pipes, their outer walls are easily oxidized to form rust spots. The outer walls of the metal bar segments or metal pipe segments need to be derusted and polished to facilitate subsequent cutting operations. It is impossible to automatically remove rust before cutting, which leads to a significant increase in the workload of cutting metal bars or metal pipes, and also reduces the cutting efficiency. For example, refer to the fully automatic high-speed metal circular saw machine mechanism with the publication number CN219986405U. The high-speed metal circular saw machine mechanism only clamps the two sides of the metal pipe through the cooperation of the pressure block and the pad block. The clamping method on both sides is not only difficult to achieve stable clamping, but also easily leads to excessive concentration of clamping force, resulting in damage to the metal pipe.

[0006] Therefore, the present invention proposes a high-speed metal circular saw machine to solve the above problems. Summary of the invention

[0024] The present invention provides a high-speed metal circular saw. Compared with the prior art, it has the following beneficial effects:

[0025] 1. A high-speed metal circular saw machine, wherein a plurality of clamping units are arranged in a ring shape in a first clamping assembly and a second clamping assembly, and the plurality of clamping units can cooperate with each other, and before cutting the same batch of metal bars or metal tubes, the arc-shaped outer wall contour of the metal bars or metal tubes can be first simulated, so that the clamping ends of the plurality of clamping units can form a contour shape that matches the outer wall of the metal bars or metal tubes, that is, the profiling clamping parts at different positions in the clamping units can adaptively adjust the height of their own ends according to the different positions of the arc-shaped outer wall of the metal tube or metal bar. The invention can disperse the single-point clamping force to multiple clamping points to achieve the multi-point clamping effect, making the clamping effect more stable and firm. Moreover, by evenly dispersing the clamping force to multiple contour clamping parts, the situation in which the surface of the metal bar or metal tube is damaged due to excessive concentration of the clamping force is avoided, thereby ensuring the integrity of the metal material during the cutting process.

[0026] 2. A high-speed metal circular saw machine, by arranging multiple profiling clamping components at different positions in a clamping unit, the multiple profiling units can simulate the external contour shapes of metal bars or metal pipes of different batches, so that they can be suitable for clamping tasks of metal plates or metal pipes of different sizes during the cutting process, making its practicality greatly improved and its application range wider; by arranging a positioning component, the positions of multiple profiling clamping components that have been determined in the simulation profiling process can be quickly and synchronously locked, so that the profiling clamping components at multiple positions can be kept in determined positions, so that the same batch of metal bars or metal pipes can be simulated once and then continue to be used in subsequent clamping work of materials of the same specification without repeated adjustment, thereby reducing the adjustment operation steps and operation difficulty, and after the positioning component releases the lock on the profiling clamping component, the profiling clamping components at multiple positions can return to their original positions, so that it is convenient to perform the simulation profiling operation of the external contour according to the new size of metal bars or pipes again.

[0027] 3. A high-speed metal circular saw machine, by arranging a flexible friction plate at the clamping end of a contour clamping component, can utilize the flexible hot spot of the friction plate so that each flexible friction plate can fit tightly with the outer wall of a metal bar or a metal pipe, thereby ensuring the clamping firmness of each clamping point, and the flexible friction plate and the mounting box are split-type design, which can be disassembled and replaced after being worn, without the need to replace the contour clamping component as a whole, thereby saving the cost of overall replacement, and the flexible friction plate can grind the outer wall of the metal bar or metal pipe before the cutting operation, so as to achieve the purpose of cleaning the metal bar or metal pipe before cutting, without the need for manual cleaning before cutting.

[0028] 4. A high-speed metal circular saw machine, which is provided with a power conversion assembly, wherein a first tapered roller and a second tapered roller are designed to slide relative to each other along a transmission shaft, and when a metal bar or a metal tube is placed on the top of the first tapered roller and the second tapered roller, the two can move away from each other under the force of the component of the weight of the metal bar or the metal tube, so that the outer wall of the first tapered roller and the second tapered roller can be in close contact with the outer wall of the metal bar or the metal tube, while not interfering with the supporting and lifting effect of the lifting mechanism on the metal bar or the metal tube, and the metal bar or the metal tube can be moved along the first tapered roller and the second tapered roller. When the outer wall of the roller slides, the No. 1 tapered roller and the No. 2 tapered roller rotate with the help of friction. The power generated by the No. 1 tapered roller and the No. 2 tapered roller can be accelerated by the transmission and then driven by the gear ring to rotate, thereby providing driving force for the rotation of the roller. Therefore, while the roller rotates, the flexible friction plates at the clamping ends of the contoured clamping components at multiple positions can grind the outer wall of the metal bar or metal pipe, so that rust or other attachments on the surface of the metal bar or metal pipe can be removed before cutting, ensuring the neatness of the outer wall of the metal bar or metal pipe after cutting.

[0072] In the embodiment of the present invention, through the mutual cooperation between the multiple clamping units 76, before cutting the same batch of metal bars or metal tubes, the contour of the arc-shaped outer wall of the metal bars or metal tubes can be simulated, so that the clamping ends of the multiple clamping units 76 can form a contour shape that matches the outer wall of the metal bars or metal tubes, not only can a multi-point clamping effect be formed on the outer wall of the metal bars or metal tubes, but also the multiple clamping units 76 can jointly constitute a relatively independent independent clamp structure that is compatible with the outer wall contour of the target metal bars or metal tubes, and can form an embracing clamping effect around the outer wall of the metal bars or metal tubes to achieve stable clamping;

[0073] In the embodiment of the present invention, the positions of the multiple profiling clamping components 769 that have been determined in the process of simulated profiling can be quickly and synchronously locked, so that the profiling clamping components 769 at multiple positions can be kept in the determined positions, so that after the outer contour of the same batch of metal bars or metal pipes is simulated once, the subsequent target clamping objects of the same specification can be stably and powerfully clamped;

[0074] In the embodiment of the present invention, the metal rod or metal tube can drive the first tapered roller a5 and the second tapered roller a6 to rotate while sliding along the outer walls of the first tapered roller a5 and the second tapered roller a6. The power generated by the rotation can be accelerated by the transmission a9 and then driven by the gear a11 to rotate the gear ring 79, thereby providing a driving force for the rotation of the roller 73. While the roller 73 is rotating, the flexible friction plates 7698 at the ends of the contoured clamping parts 769 at multiple positions can grind the outer wall of the metal rod or metal tube, so that rust or other attachments on the surface of the metal rod or metal tube can be removed before cutting, thereby ensuring the neatness of the outer wall of the metal rod or metal tube after cutting.

[0075] like Figure 25-27 A fourth embodiment is shown: the power conversion assembly 710 includes a base a1 detachably arranged on the top of the mounting frame 6 and a roller frame a2 fixedly arranged on the top of the base a1, the inner wall of the roller frame a2 is provided with a power conversion assembly, the power conversion assembly includes a transmission shaft a3 rotatably arranged on the inner wall of the roller frame a2, and a long strip limit block a4 is also fixedly arranged on the outer wall of the transmission shaft a3, a first tapered roller a5 and a second tapered roller a6 are slidably sleeved on both sides of the outer wall of the transmission shaft a3, and the inner walls of the first tapered roller a5 and the second tapered roller a6 are provided with limit slots adapted to the structure of the long strip limit block a4, and the outer wall of the transmission shaft a3 is respectively provided with a first tapered roller a5 and a second tapered roller a6. A third spring a7 is slidably sleeved between the first tapered roller a5, the second tapered roller a6 and the side wall of the roller frame a2, one end of the transmission shaft a3 rotates through the roller frame a2 and is connected to a transmission assembly for driving the gear ring 79 to rotate; the height between the first tapered roller a5 and the second tapered roller a6 is lower than the axial position of the roller 73, and the first tapered roller a5 and the second tapered roller a6 do not play a major supporting role for the long rods or long tubes. When the first tapered roller a5 and the second tapered roller a6 are subjected to the gravity of the long rods or long tubes of various sizes, they can slide to both sides along the outer wall of the transmission shaft a3, so they will not interfere with the support of the lifting assembly for the long rods or long tubes;

[0076] The transmission assembly includes a worm a8 fixedly connected to one end of a transmission shaft a3 and a transmission a9 fixedly arranged on the side wall of a base a1 via a mounting bracket, a worm wheel a10 meshingly connected to the worm a8 is fixedly arranged on the input shaft of the transmission a9, and a gear a11 meshingly connected to a gear ring 79 is fixedly arranged on the output shaft of the transmission a9.

[0077] When in use, the metal material cut by the high-speed metal circular saw machine of the present invention includes a long bar or a long tube. First, the clamping shapes of the first clamping assembly 7 and the second clamping assembly 8 are simulated and imitated according to the outer contour shape of the long bar or long tube to be cut;

[0078] During the simulation profiling, the long bar or long tube to be cut is placed on the top of the feeding rack 2, and the feeding rack 2 gradually transports the long bar or long tube to the direction of the clamping mechanism 5. After the long bar or long tube enters the top of the multiple rollers 13, one end of the long bar or long tube continues to pass through the No. 2 clamping assembly 8 and enter the No. 1 clamping assembly 7, and then the No. 2 electric push rod 14 is controlled according to the size of the long bar or long tube to be cut to push the support plate 12 up or down to a preset height. Since the height of the top of the roller 13 from the axial position of the roller 73 is a known value, the roller 13 can be adjusted to the preset height in combination with the size of the long bar or long tube to be cut, so as to keep the axial height of the long bar or long tube to be cut and the axial height of the roller 73 at the same level;

[0079] Next, start the No. 1 cylinder 9 and the No. 2 cylinder 10 to synchronously pull the push rod 78 in the No. 1 clamping assembly 7 and the No. 2 clamping assembly 8. At this time, the drive ring 77 in the No. 1 clamping assembly 7 and the No. 2 clamping assembly 8 is synchronously pulled by the upper and lower pull rods 11 and gradually slides from low to high along the slope surface of the multiple wedge plates 762. The multiple wedge plates 762 are driven by the drive ring 77 and gradually move toward the inner direction of the roller 73. At this time, the lifting rod 763 moves downward along the inner wall of the installation groove 75, the No. 1 spring 764 is compressed and elastically deformed, and the bottom ends of the multiple contoured clamping components 769 synchronously approach the direction of the long rod or long tube until the flexible friction plate 7698 The bottom of the profiling clamping parts 769 contacts the outer wall of the long rod or long tube. Since the distribution positions of the multiple profiling clamping parts 769 are different, the contact positions with the long rod or long tube are also different. Since the outer wall of the long rod or long tube is arc-shaped, when the profiling clamping parts 769 at multiple positions are squeezed by the outer wall of the long rod or long tube, the square column 7691 moves up along the square through hole inside the partition 768, and the through hole 7693 slides upward along the outer wall of the guide rod 7694. The second spring 7695 is squeezed by the square column 7691 and elastically deformed. At this time, the bottom ends of the profiling clamping parts 769 at multiple positions jointly form a contour shape that matches the shape of the outer wall of the long rod or long tube.

[0080] Next, the No. 1 electric push rod 717 is started to pull the linkage plate 716 toward the roller 73. The arc-shaped slider 715 is pushed by the linkage plate 716 and synchronously pushes the ring frame 712 toward the roller 73. Since the limit blocks 7613 in each clamping unit 76 are respectively slidably arranged in the sliding sleeves 713 at the corresponding positions, when the ring frame 712 slides along the inner walls of the multiple slide grooves 711 toward the inside of the roller 73, the connecting rod 7612 pushes the long pull rod 7611 to move, and the multiple limit tooth plates 7610 fixedly connected to the long pull rod 7611 and the limit teeth 7692 in the corresponding position of the profiling clamping component 769 are meshed and connected with each other. At this time, the positions of the profiling clamping components 769 at multiple positions are locked, and the simulation operation of the outer wall contour shape of the long bar or long tube is completed.

[0081] Next, the No. 1 cylinder 9 and the No. 2 cylinder 10 are started to push the pull rod 11 in the opposite direction, and the drive ring 77 in the No. 1 clamping assembly 7 and the No. 2 clamping assembly 8 slides from the slope surface at the higher position of the clamping unit 76 to the lower position, and the wedge plate 762 moves upward along the inner wall of the mounting groove 75 under the elastic force of the No. 1 spring 764 until the clamping unit 76 returns to its original position. At this time, the clamping of the long rod or long tube is released. After the clamping is released, the bottom of the flexible friction plate 7698 at multiple positions is still tightly fitted with the outer wall of the long rod or long tube. When the long rod or long tube moves, sliding friction is still generated between the bottom of the flexible friction plate 7698, and the sliding friction will not limit the movement of the long rod or long tube. In this process, the limit tooth plate 7610 is always in a state of mutual meshing with the limit tooth 7692.

[0082] Next, the long rod or long tube of the same type as the above can be cut. The long rod or long tube is transported to the top of multiple rollers 13 by the feeding rack 2, and one end of the long rod or long tube passes through the No. 2 clamping assembly 8 and enters the No. 1 clamping assembly 7. In this process, the long rod or long tube slides between the No. 1 tapered roller a5 and the No. 2 tapered roller a6. When subjected to the gravity of the long rod or long tube, the No. 1 tapered roller a5 and the No. 2 tapered roller a6 can slide to both sides along the outer wall of the transmission shaft a3. Since the No. 1 tapered roller a5 and the No. 2 tapered roller a6 are rotated by the friction force of the long rod or long tube, the transmission shaft a3 drives the worm gear a10 to rotate. Since the worm a8 and the worm gear a10 are meshed and connected with each other, The power is transmitted to the interior of the transmission a9 through the worm gear a10 and the input shaft of the transmission a9. After the acceleration of the transmission a9, the gear a11 is able to rotate rapidly. When the gear a11 drives the gear ring 79 to rotate, the flexible friction plates 7698 at the bottom of the contoured clamping component 769 at multiple positions slide around the outer wall of the long rod or long tube. In this process, the rust attached to the outer wall of the long rod or long tube is polished off, and the polishing waste is discharged from the roller 73 through the chip discharge groove 74. When one end of the long rod or long tube enters the bottom of the high-speed metal circular saw machine 3, the high-speed metal circular saw machine 3 cuts the long rod or long tube according to the preset length, and the cut rod segments or tube segments are discharged through the discharge port on one side of the operating box 1.
