[0002] At present, many laser cutting machines are equipped with push-pull cutting platforms, which push out the cutting platforms when loading and unloading materials, providing great convenience for the application of laser cutting machines. However, the push-pull cutting platforms of laser cutting machines generally have the problem of low load-bearing capacity, which cannot meet the load-bearing requirements of heavy materials such as whole plates and thick plates. During the push-pull process, due to the heavy weight of the materials, jamming is prone to occur. In addition, the push-pull cylinders of existing cutting platforms are mostly directly exposed and installed. During the cutting process, the cutting material residues can easily splash onto the push-pull cylinders, causing the cylinders to run poorly. Summary of the invention

[0005] Furthermore, shielding plates are integrally provided on the top surfaces of the two side frames of the metal frame of the support stand, and the shielding plates on both sides extend to both sides respectively to cover the push-pull cylinders on both sides.

[0006] Furthermore, the interior of the metal frame is a tic-tac-toe-shaped support frame, and the bottom surfaces of its two longitudinal frames are respectively provided with groove plates along the length direction. Two longitudinal beams are provided in the middle part of the body frame corresponding to the positions of the two longitudinal frames of the metal frame. Multiple rollers are respectively embedded on the two longitudinal beams, and the upper sides of the rollers on the two longitudinal beams are located in the groove plates to support the metal frame.

DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the utility model are clearly and completely described, and the described embodiments are only embodiments of a part of the invention, not all of it. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0014] like Figure 1-3As shown, the utility model patent designs an embodiment of a push-pull cutting platform of a fiber laser cutting machine. In this embodiment, the push-pull cutting platform includes a support frame 1, and the support frame 1 includes a metal frame 11 and a support grid 12. The metal frame 11 is welded from square steel and other profiles, and the interior is in a well shape, wherein the bottom of the two profiles arranged in the longitudinal direction are provided with roller grooves in the length direction. The support grid 12 is composed of a plurality of vertically arranged metal plates evenly arranged on the bottom frame, and is fixedly installed on the upper side of the metal frame 11.

[0015] An angle steel seat 45 is fixed to the top surface of the side frame of the machine frame 4 in the longitudinal direction, and a push-pull cylinder 2 is fixed to the side surface of the bottom plate of the angle steel seat 45 in the longitudinal direction. The ends of the piston rods of the push-pull cylinders 2 on both sides are connected to the front ends of the frames 13 on both sides of the metal frame 11 of the support stand 1 through connecting plates, and the support stand 1 is pushed by the push-pull cylinder 2 to move in the longitudinal direction. A heavy-duty slide rail 3 is fixed to the outer side surface of the vertical plate of the angle steel seat 45 in the longitudinal direction, and is slidably connected to the frames 13 on both sides of the metal frame 11 through the heavy-duty slide rail 3. The heavy-duty slide rail 3 is an existing commercial product, using a thickened stainless steel plate body, and the internal rollers are solid steel balls. Positioning plates 41 are respectively installed at the front of the side frames on both sides of the machine frame 4 through bolts. The positioning plates 41 are L-shaped, and the vertical plate portion is connected and fixed to the machine frame 4, and the flat plate portion extends to the upper side of the frames 13 on both sides of the metal frame 11. A row of rollers are embedded and installed on the bottom surface of the flat plate portion, and the bottom surface of the rollers is pressed on the upper side of the frames 13 on both sides.

[0016] Two longitudinal beams 43 are longitudinally arranged inside the body frame 4, and the positions of the two longitudinal beams 43 correspond to the positions of the two longitudinally arranged profiles inside the upper metal frame 11. A plurality of rollers 44 are longitudinally arranged and embedded on the two longitudinal beams 43 respectively. The rollers 44 extend beyond the upper side surfaces of the longitudinal beams 43 and are located in two roller grooves at the bottom of the metal frame 11, thereby providing support for the metal frame 11.

[0017] When the push-pull cutting platform of the fiber laser cutting machine disclosed in the utility model patent is used, the push-pull cylinders 2 on both sides are synchronously extended and retracted to drive the support frame 1 to move longitudinally on the machine frame 4. The heavy-duty slide rails 3 on both sides constitute the sliding track of the support frame 1. The rollers 44 on the bottom side support the support frame 1. At the same time, the positioning plates 41 on both sides of the front press the support frame to prevent the support frame 1 from overturning due to excessive weight of the material after it is extended forward.

[0018] The above contents are only preferred embodiments of the present invention and cannot be used to limit the scope of implementation of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
