Description

Technical Field

[0001] This invention relates to the field of metal material processing technology, specifically to a metal material cutting device. Background Technology

[0002] Metallic materials are materials that possess properties such as luster, ductility, and good electrical and thermal conductivity. They are generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, iron and steel are basic structural materials.

[0003] Patent CN114309793A discloses a cutting device for metal material production, including a support table, a drive shaft, and a rotating plate. Multiple symmetrically arranged support legs are fixedly installed on the bottom of the support table. A pair of symmetrically arranged side plates are fixedly installed on the front and rear sides of the upper surface of the support table. A first worm and a second worm are rotatably installed on the left and right sides between the pair of side plates. The first and second worms are configured to have identical parameters. One end of the first and second worms is respectively connected to the output ends of a first motor and a second motor. A worm wheel is disposed between the first and second worms, with both ends of the worm wheel meshing with the first and second worms respectively. The transmission mechanism includes a drive shaft with one end fixedly mounted in a worm gear and the other end of the drive shaft away from the worm gear fixedly connected to the bottom of a rotating plate. A forward and backward movement guide mechanism is located in the middle of the drive shaft. An adjustable clamping mechanism is located on the upper surface of the rotating plate. Symmetrically arranged support frames are fixedly mounted on the left and right sides of the upper surface of the support platform. A mounting frame is fixedly mounted on the top of the support frame, and a motor mounting cover is located on the lower side of the mounting frame. A cutting lifting transmission mechanism is located between the motor mounting cover and the mounting frame. A cutting motor is fixedly mounted inside the motor mounting cover, and the output end of the cutting motor is fixedly connected to the rotating shaft. One end of the rotating shaft extends through the motor mounting cover and is fixedly mounted with a cutting blade. Through the cooperation of the first worm, the second worm, and the worm gear, the worm gear can both rotate and move forward and backward. The drive shaft and the forward and backward movement guide mechanism drive the rotating plate to rotate and move, allowing the metal material clamped on the upper surface of the rotating plate to move forward and backward and rotate. This enables automatic cutting of the metal material and allows adjustment of the cutting angle, eliminating the need for manual pushing and improving the safety of metal cutting.

[0004] In the above technical solution, one end of the rotating shaft extends through the motor mounting cover and is fixedly mounted with a cutting blade. Different types of cutting blades are required for different metal materials. The cutting effect can be improved by using cutting blades that are suitable for the material. Currently, manually changing the cutting blade will greatly reduce the efficiency of the machine and make the machine inconvenient to use.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] (1) A metal material cutting device that automatically replaces the saw blade mechanism through a cutting mechanism and a blade magazine assembly for different metal materials in order to improve the cutting efficiency of metal materials.

[0035] (2) A metal material cutting device, wherein the saw blade mechanism is transferred from the shaft frame assembly to the support foot, and then the guide frame is rotated to the upward deflection. Under the action of gravity, the saw blade mechanism automatically slides into the arc blade sleeve for placement, thereby completing the automatic disassembly of the saw blade mechanism and improving the unloading efficiency.

[0036] (3) A metal material cutting device, wherein when the guide is deflected upward, the shaft of the saw blade mechanism rolls along the guide towards the arc blade sleeve, and when the saw blade mechanism rolls to the end of the guide, it can be aligned and automatically roll into the arc blade sleeve, thereby improving the accuracy of the automatic positioning of the saw blade mechanism.

[0037] (4) A metal material cutting device, by the tendency of the arc blade sleeve to slide and tilt, the saw blade mechanism supported on the sinking frame mechanism is dislodged and carried by the guide frame. The guide frame is deflected downward so that the saw blade mechanism slides down to the support foot under the action of gravity. Then, the shaft cylinder is carried by the support clamp, the support foot is flipped to the side, the second cylinder is retracted to bring the saw blade mechanism into the protective shell, the power components on both sides are started and the saw blade mechanism is assembled. Then, the protective shell is flipped by the second rotator, and the cutting mechanism is returned to its position by the moving seat assembly, thus completing the switching of the saw blade mechanism and improving the automation performance of the saw blade mechanism switching.

[0038] (5) A metal material cutting device, wherein when the selection mechanism returns to its position and retracts the selection clamp, the first rack and the second rack move together, causing the arc blade sleeve to tilt and the saw blade mechanism to be sent onto the guide frame. The two sets of operation processes are linked together, thereby improving the efficiency of switching the saw blade mechanism.

[0039] (6) A metal material cutting device in which the arc sleeve tilts during the retraction of the selector clamp, but after the selector clamp leaves the sinking mechanism, the arc sleeve can return to its original position under the gravity of the counterweight without the need for additional power to return it to its original position, thus saving energy and reducing costs.

[0040] (7) A metal material cutting device, in the process of assembling the saw blade mechanism and the power component, the rail column moves along the second electric rail toward the saw blade mechanism. At this time, the grinding machine is started and drives the saw blade mechanism to rotate through contact with the saw blade, so that the ball and the ball groove are aligned and clamped, thereby improving the accuracy of the assembly of the saw blade mechanism.

[0041] (8) A metal material cutting device, wherein when the first rotator of the starting power component drives the saw blade mechanism to rotate and cut the metal material, friction occurs between the saw blade and the grinder, thereby grinding the saw blade, ensuring the sharpness of the saw blade, and improving the service life of the saw blade mechanism.

[0042] (9) A metal material cutting device, which can be used with a variety of different saw blade mechanisms by arranging multiple sets of blade holder components in the blade magazine, thereby enabling it to work on a variety of cutting types and materials, thus improving its applicability.

[0083] Each support leg assembly includes a semi-circular arc plate seat 701, a base column 702 is fixedly connected to the lower side of the arc plate seat 701, a base block 703 is fixedly connected to the lower end of the base column 702, the base column 702 and the base block 703 are inserted into a base cylinder 704 of the fixed connection frame 601, and a spring 705 wrapped around the base column 702 is fixedly connected between the base block 703 and the base cylinder 704.

[0084] A groove 706 is provided on one side of the inner arc surface of the arc plate seat 701, and a third tooth groove 707 is provided through the other side of the inner arc surface of the arc plate seat 701.

[0087] The fourth electric rail 503 has a U-shaped selection clip 505 that is slidably inserted inside. The front ends of both sides of the selection clip 505 are respectively fixedly connected to the first rack 506 that is adapted to be inserted into the first tooth groove 504.

[0088] The first rack 506 is adapted to be inserted into the third tooth groove 707, and the first rack 506 is adapted to be engaged with the second rack 710.

[0089] The working principle of this invention is as follows:

[0090] The metal material to be cut is fixed on the cross slide 106. The lifting device 105 and the cross slide 106 move the metal material to a suitable position. The metal material is cut by the part of the saw blade 301 that extends from the cut 104.

[0091] For different metal materials, the saw blade mechanism 3 is automatically replaced by the cutting mechanism 2 and the blade magazine assembly to improve the cutting efficiency of metal materials.

[0092] When the saw blade mechanism 3 needs to be replaced, the cutting mechanism 2 is first lifted by the first cylinder 108 to disengage it from the cutting edge 104. Then, the protective shell 201 is rotated 180 degrees by the second rotator 211. The sliding post 206 along the second electric rail 205 causes the cylinder 208 and the ball 209 to disengage from the shaft cylinder 302 and the ball groove 303, respectively. At this time, the saw blade mechanism 3 is only supported by the shaft frame assembly. The sliding rail block 212 along the first electric rail 107 aligns the saw blade mechanism 3 with the unloaded blade holder assembly. The ring rail 602 is then activated to rotate the turntable 603. The guide frame 604 is deflected downwards to align with the cutting mechanism 2. The electric shaft 608 is activated to drive the support foot 609 to rotate to the side. At this time, the second cylinder 203 is activated to extend and send the saw blade mechanism 3 into the front end of the guide frame 604. After the saw blade mechanism 3 is in place, the support foot 609 is flipped back to its original position by the electric shaft 608, thereby transferring the saw blade mechanism 3 from the shaft frame assembly to the support foot 609. Then, the guide frame 604 is rotated upwards, and the saw blade mechanism 3 automatically slides into the arc blade sleeve 708 under the action of gravity, completing the automatic disassembly of the saw blade mechanism 3 and improving the efficiency of blade removal.

[0093] Under the action of spring 705, in its natural state, the bottom block 703 is placed at the bottom of the bottom cylinder 704. At this time, the position of the arc blade sleeve 708 is flush with the guide frame 604 in the horizontal state. When the guide frame 604 deflects upward, the shaft cylinder 302 of the saw blade mechanism 3 rolls along the guide frame 604 toward the arc blade sleeve 708. When the saw blade mechanism 3 rolls to the end of the guide frame 604, it can be aligned and automatically roll into the arc blade sleeve 708, improving the accuracy of the automatic positioning of the saw blade mechanism 3.

[0094] The unloaded cutting mechanism 2 is moved to align with another tool holder assembly, and the third cylinder 502 is slid along the third electric rail 501 to align the selection clip 505 with the same tool holder assembly. The selection clip 505 is then extended from the fourth electric rail 503 and inserted into the sinker mechanism 7. Next, the third cylinder 502 is retracted to bring the selection clip 505 into contact with the arc plate seat 701, and the first rack 506 is inserted into the third tooth groove 707. The third cylinder 502 is retracted again to lift the arc plate seat 701 and the arc plate sleeve 708 onto the guide frame 604. Then, the selection clip 505 is retracted, causing the first rack 506 and its meshing second rack 710 to move together, causing the arc plate sleeve 708 to move between the counterweight 709 and the slide groove 706. Guided by the arc blade seat 701, the saw blade mechanism 3 supported on the sinking frame mechanism 7 is dislodged by the sliding tilt of the arc blade sleeve 708 and carried by the guide frame 604. The guide frame 604 is deflected downward, causing the saw blade mechanism 3 to slide down to the support foot 609 under the action of gravity. Then, after the shaft cylinder 302 is supported by the clamp 204, the support foot 609 is flipped to the side. The second cylinder 203 is retracted to bring the saw blade mechanism 3 into the protective shell 201. The power components on both sides are started and the saw blade mechanism 3 is assembled. Then, the protective shell 201 is flipped by the second rotator 211, and the cutting mechanism 2 is returned to its position by the moving seat assembly, completing the switching of the saw blade mechanism 3 and improving the automation performance of switching the saw blade mechanism 3.

[0095] When the selection mechanism 5 returns to its original position and retracts the selection clamp 505, the first rack 506 and the second rack 710 move together, causing the arc blade sleeve 708 to tilt and sending the saw blade mechanism 3 onto the guide frame 604. The two sets of operation processes are linked, improving the efficiency of switching the saw blade mechanism 3.

[0096] After the arc sleeve 708 tilts during the retraction of the selector clamp 505, it can return to its original position under the gravity of the counterweight block 709 after the selector clamp 505 leaves the sinking mechanism 7. No additional power is needed to return it to its original position, thus saving energy and reducing costs.

[0097] During the assembly of the saw blade mechanism 3 and the power assembly, the rail post 206 moves along the second electric rail 205 toward the saw blade mechanism 3. At this time, the grinding machine 202 is activated and drives the saw blade mechanism 3 to rotate through contact with the saw blade 301, so that the ball 209 and the ball groove 303 are aligned and fitted, improving the accuracy of the assembly of the saw blade mechanism 3.

[0098] When the first rotator 210 of the starting power unit drives the saw blade mechanism 3 to rotate and cut metal materials, friction occurs between the saw blade 301 and the grinder 202, thereby grinding the saw blade 301, ensuring the sharpness of the saw blade 301 and improving the service life of the saw blade mechanism 3.

[0099] By arranging multiple sets of tool holder assemblies within the tool magazine 401, it can be used with various different saw blade mechanisms 3, thereby enabling it to work on various cutting types and materials, thus improving its applicability.

[0100] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
