Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, specifically to a sheet metal laser cutting machine. Background Technology

[0002] Sheet metal processing requires cutting and trimming of workpieces. Most common sheet metal parts are large-area sheet metal structures. When laser cutting is performed, a matching large-area worktable is required. The working principle of laser cutting is to ablate and cut the workpiece with a high-energy laser. The laser beam will also damage the worktable. Therefore, laser cutting machines will install a protective base pad mechanism on the worktable to protect it. As a result, the protective mechanism in existing laser cutting machines is a large-volume mechanism that is adapted to the equipment. When it is damaged, it often needs to be replaced as a whole. Therefore, we need to improve the laser cutting machine and its internal protective mechanism. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a sheet metal laser cutting machine. This machine features multiple rotating protective structures that move with the laser, allowing the overall protective structure to move and protect the worktable during cutting. The protective structure is also designed to be replaced or replaced when damaged or when it reaches its maximum capacity due to prolonged operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] It includes a ground rail and a base, wherein the base is slidably mounted on the ground rail, and a stepping system is fixedly installed on the base. It also includes:

[0006] The frame is fixedly mounted on the base;

[0007] A base support mechanism, wherein the base support mechanism is mounted on the frame;

[0008] The laser is fixedly mounted on the frame and positioned above the base support mechanism.

[0009] When in use, the workpiece is placed between the laser and the base support mechanism and the workpiece is cut by installing a ground rail on the worktable. The workpiece slides on the ground rail through the base, which in turn drives the laser to move and cut the workpiece. After the laser penetrates the workpiece, the laser beam hits the base support mechanism.

[0010] Preferably, the base support mechanism comprises:

[0011] Mounting bracket, which is fixedly mounted on the frame;

[0012] A support shaft, which is spun onto a mounting bracket via bearings;

[0013] The support base consists of several support bases that are evenly distributed at angles and fixedly mounted on the support shaft.

[0014] Adjusting component, wherein the adjusting component is disposed on the base and is configured to cooperate with the support shaft;

[0015] During use, after a single carrier has been continuously subjected to a certain amount of laser irradiation, the support shaft is rotated by the adjusting component, thereby adjusting the idle carrier to be below the laser, thus realizing the rotation of the carrier.

[0016] Preferably, the transfer component comprises:

[0017] A reciprocating pneumatic rod, wherein the reciprocating pneumatic rod is fixedly mounted on the base;

[0018] A toothed assembly, wherein the toothed assembly is disposed on the shaft end of a reciprocating pneumatic rod;

[0019] A one-way gear is fixedly mounted on a support shaft and is configured to cooperate with a gear-shifting assembly.

[0020] Preferably, the tooth assembly comprises:

[0021] The slide rail is fixedly mounted on the base.

[0022] The slider is slidably mounted on the slide rail and is fixedly mounted on the output shaft of the reciprocating pneumatic rod.

[0023] A support sleeve, which is fixedly mounted on the slider;

[0024] A support rod, wherein the support rod is movably inserted into the support sleeve;

[0025] A one-way rack, wherein the one-way rack is fixedly mounted on one end of the support rod that extends out of the support sleeve;

[0026] A support spring is sleeved on a support rod and sandwiched between the support sleeve and a one-way rack.

[0027] In use, the reciprocating pneumatic rod drives the slider to move forward, which in turn drives the one-way rack to move forward. The one-way rack then abuts against the one-way gear, causing the one-way gear to rotate, which in turn drives the support shaft to rotate. When the slider moves in the reverse direction, the one-way rack moves in the reverse direction. At this time, the one-way rack is abutted by the one-way gear and moves to one side of the slider, so that the one-way rack passes over the tooth surface of the one-way rack without driving the one-way gear to rotate. The one-way rack is pushed against the tooth surface of the one-way rack by the support spring.

[0028] Preferably, a drive gear is fixedly mounted on the support shaft, a transmission shaft is fixedly mounted on the base, a driven gear is fixedly mounted on the transmission shaft, the driven gear meshes with the drive gear, an eccentric wheel is fixedly mounted on the transmission shaft, a buffer sleeve is screwed onto the base via a rotating shaft, a buffer rod is movably inserted into the buffer sleeve, a connecting rod is fixedly mounted at one end of the buffer rod extending out of the buffer sleeve, the movable end of the connecting rod is eccentrically screwed onto the eccentric wheel via a rotating shaft, a buffer spring is sleeved on the buffer rod, and the buffer spring is sandwiched between the buffer sleeve and the connecting rod;

[0029] When the one-way rack moves the one-way gear to rotate one stroke interval, the support shaft drives the driving gear to rotate one stroke interval, which in turn drives the driven gear to rotate, which in turn drives the transmission shaft to rotate. The transmission shaft drives the eccentric wheel to rotate one revolution. At this time, the eccentric wheel drives the buffer rod to slide in the buffer sleeve through the connecting rod to complete one extension stroke. After completing one extension stroke, the buffer spring pushes the buffer rod out and presses it. Then, when the one-way rack moves to reset, the buffer spring presses against the connecting rod to limit the eccentric wheel. That is, the one-way gear is limited after transmission through the transmission shaft, driven gear, driving gear, and support shaft. In other words, the rotation of the one-way gear is restricted when the one-way rack slides to reset.

[0030] Preferably, six bearing seats are provided, with a 60° angle between two adjacent bearing seats. The ratio of the length stroke of the one-way rack to the circumferential stroke of the one-way gear is 1:6, and the transmission ratio of the driven gear to the driving gear is 1:6.

[0031] Preferably, a telescopic pneumatic rod is fixedly mounted on the mounting bracket, and a heat-conducting plate is fixedly mounted on the output shaft of the telescopic pneumatic rod, with the heat-conducting plate abutting against the side wall of one of the bearing seats.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. This device uses a support base placed below the laser, and then moves the laser and the support base simultaneously to absorb and protect the laser that penetrates the workpiece during cutting.

[0034] 2. This device has several support seats, and the support seats are switched by rotating the one-way gear on the support shaft through a reciprocating one-way rack. Attached Figure Description

[0060] Support sleeve 7-3 is fixedly mounted on slider 7-2;

[0061] Support rod 7-4, wherein the support rod 7-4 is movably inserted into support sleeve 7-3;

[0062] One-way rack 7-5, wherein the one-way rack 7-5 is fixedly mounted on the support rod 7-4 and extends out of the support sleeve 7-3 at one end;

[0063] A support spring 7-6 is sleeved on the support rod 7-4 and is sandwiched between the support sleeve 7-3 and the one-way rack 7-5.

[0064] The drive gear 8 is fixedly mounted on the support shaft 5-2;

[0066] Driven gear 10 is fixedly mounted on transmission shaft 9 and meshes with driving gear 8;

[0073] Telescopic pneumatic rod 16, wherein the telescopic pneumatic rod 16 is fixedly mounted on the mounting bracket 5-1;

[0074] The heat-conducting plate 17 is fixedly mounted on the shaft end of the telescopic pneumatic rod 16, and the heat-conducting plate 17 covers the side wall of one of the bearing seats 5-3.

[0075] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0076] When using this device, the workpiece is placed between the support base 5-3 and the laser 4. The base 2 slides on the ground rail 1, thereby driving the frame 3 and the mounting frame 5-1 to move. Then the laser 4 moves to cut the workpiece. After the laser beam of the laser 4 penetrates the workpiece, the laser beam shines on the support base 5-3 for absorption and protection.

[0077] After a single bearing seat 5-3 has been subjected to laser irradiation for a certain period of time, the reciprocating pneumatic rod 6-1 drives the slider 7-2 to move forward on the slide rail 7-1. Then, the slider 7-2 drives the one-way rack 7-5 to move forward and pushes the one-way gear 6-2 to rotate 60°. Then, the one-way gear 6-2 drives the support shaft 5-2 to rotate, and the support shaft 5-2 drives the next bearing seat 5-3 to move below the workstation.

[0078] When the support shaft 5-2 rotates 60°, it drives the rotating gear to rotate. The driving gear 8 drives the driven gear 10 to rotate 360°, which in turn drives the transmission shaft 9 to rotate. The transmission shaft 9 drives the eccentric wheel 11 to rotate 360°. During the rotation of the eccentric wheel 11, it drives the buffer rod 13 through the connecting rod 14 from the insertion of the buffer sleeve 12 to the extension of the buffer sleeve 12. The buffer rod 13 is held in place by the buffer spring 15 between the connecting rod 14 and the buffer sleeve 12, keeping the buffer rod 13 extended. The trend is such that when the one-way rack 7-5 resets, the eccentric wheel 11 is restricted from rotating by the holding force of the buffer spring 15, and after transmission through the transmission shaft 9, driven gear 10, driving gear 8, and support shaft 5-2, the one-way gear 6-2 is restricted from rotating in the opposite direction as the one-way rack 7-5 resets. Then, when the one-way rack 7-5 resets, the one-way rack 7-5 passes over the tooth surface of the one-way gear 6-2, and the one-way rack 7-5 is pressed against the one-way gear 6-2 by the support spring 7-6.

[0079] The technical advantages achieved by adopting the above technical solution are as follows:

[0080] 1. This device sets up a support base 5-3 below the laser 4, and then moves the laser 4 and the support base 5-3 simultaneously to absorb and protect the laser that penetrates the workpiece during cutting.

[0081] 2. The device has several bearing seats 5-3, and the one-way gear 6-2 on the support shaft 5-2 is rotated by a reciprocating one-way rack 7-5 to achieve the switching of bearing seats 5-3.

[0082] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
