[0002] During the production process of guide rails, a linear cutting device is used to linearly cut the steel plate raw material so as to cut the steel plate into small guide rail blanks.

[0003] Linear cutting devices are currently generally divided into two categories. One category is that the cutting blade does not move, and the platform drives the cutting material to move, such as the utility model patent with patent publication number CN219520746U. The other category is that the platform and the cutting material do not move, but the cutting blade moves, such as the laser cutting machine with patent publication number CN210413104U. However, if the above-mentioned mechanism is set up to cut larger pieces of steel, the overall design size needs to be relatively large, the overall structure is relatively complex, and it is relatively bulky. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a linear cutting device for steel, used for cutting steel plates, including a linear cutting knife and a controller for controlling the movement of the linear cutting knife, and also including a support box, a movable frame, a first steel rail and a second steel rail. The support box is rectangular, and the top of the support box is an open structure. A placement plate is detachably connected to the upper position of the support box. The upper plane of the placement plate is lower than the top surface of the support box. The steel plate is placed above the support box. A base is fixed to the bottom of the front and rear sides of the first steel rail. The first steel rail is placed on the steel plate. The movable frame is slidably connected to the first steel rail for forward and backward sliding. The middle part of the movable frame is slidably connected to the second steel rail for left and right sliding. The second rail is provided with a driving mechanism that can drive it to slide, and the linear cutting knife is fixed on one side of the second steel rail.

[0006] As a further improvement of the present invention, a plurality of first ventilation holes are provided on the placement plate.

[0007] As a further improvement of the present invention, a second air vent is provided on the placement box.

[0008] As a further improvement of the present invention, an openable door is provided on the front side of the support box.

[0009] As a further improvement of the present invention, a slide groove is provided inside the movable frame, and the second rail is slidably connected in the slide groove of the movable frame.

[0010] As a further improvement of the present invention, a support bar is fixed on the inner wall of the support box at the position where the placement plate is set, and the placement plate is placed on the support bar.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. By setting a support box, the steel plate is placed on the support box, the first steel rail, the movable frame and the second steel rail are set, the base is set on the second steel rail, the second steel rail is placed on the steel plate, and then the movable frame is moved. The movable frame can slide back and forth with the second steel rail and the linear cutting knife, and the left and right sliding of the second steel rail can drive the linear cutting knife to slide left and right. After cutting the steel plate on one side of the movable frame, the second steel rail can be moved to cut the remaining steel plates. The device only needs to support the steel plate through the support box, and the linear cutting knife can be driven to move by the first steel rail, the second rail and the movable frame. The overall structure is relatively simple and simplified, easy to make, lightweight, and has strong economy.

[0013] In addition, the first rail is not fixedly connected to the support box, so the first rail, the movable frame, the second rail and the linear cutter can be moved, disassembled and transferred for application in other aspects, and the maintenance of the support box is convenient, making it more flexible to use.

[0014] The placement plate provided on the support box is used to support the cut small steel plates or rails, and the upper plane of the placement plate is lower than the top surface of the support box, which can prevent the cutting knife from cutting the steel plates and causing damage to the placement plate.

[0015] 2. By setting the first air vent on the placement plate, it can not only allow ventilation and facilitate the dissipation of cutting heat at the bottom of the cutting steel plate, but also allow the cutting waste to fall into the support box for temporary storage.

[0016] 3. A second vent hole is provided on the placement box to facilitate the dissipation of cutting heat.

[0017] 4. A door is provided on the front side of the support box to facilitate removal of the residue in the support box. BRIEF DESCRIPTION OF THE DRAWINGS
