After the sliding door 4 is opened, the workpiece can be loaded by hoisting. Whether the sliding door 4 is opened or closed, the position stability of the sliding door 4 can be maintained by magnetic attraction.

[0030] As shown in Figure 4 , the front part of the sliding door 4 is an arc-shaped plate 43 bent downward, which is convenient for cooperation with the top space of the front door 22, plays a protective role, and also makes the appearance of the equipment more beautiful.

[0031] The sliding door 4 is provided with three rollers 41 on both sides, which can roll on the rails 51. A total of six rollers 41 are provided, which are equivalent to a skateboard.

[0032] The translation mechanism adopts a screw nut mechanism, including a translation slider and a translation screw 61. The axial direction of the translation screw 61 is arranged in the front-rear direction.

[0033] As shown in Figure 5 , the lifting mechanism includes a support 62 and a lifting slider 64. The lower part of the support 62 is fixed on the translation slider, and the lifting slider 64 is slidingly assembled on the support 62. When the translation slider moves in the front-rear direction, it can drive the support 62 to move in the front-rear direction. The lifting slider 64 is driven by a lifting screw 63 to form a screw nut mechanism, so that the lifting slider 64 performs lifting action in the vertical direction.

[0034] The flat cutting mechanism includes a cutting support 71 and a wire cutting mechanism. The cutting support 71 is fixed on the lifting slider 64. Under the action of the translation mechanism and the lifting mechanism, the wire cutting mechanism can be translated and lifted.

[0035] As shown in Figure 5 , the wire cutting mechanism includes a driving wire wheel 72, a tensioning wheel 74, a guide wheel 73 and a diamond cutting wire. The diamond cutting wire is arranged in a ring around the driving wire wheel 72, the tensioning wheel 74 and the guide wheel 73. The guide wheel 73 has two. The driving wire wheel 72, the tensioning wheel 74 and the guide wheel 73 are installed on the cutting support 71 and are distributed in a rectangular shape. The rotation axes of the driving wire wheel 72, the tensioning wheel 74 and the guide wheel 73 are all in the vertical direction. The driving wire wheel 72 is assembled on a driving shaft and is driven by a servo motor. Figure 6 As shown in , the tensioning wheel 74 is a driven wheel. In this embodiment, the tensioning wheel 74 is tensioned by a cylinder 81.

[0036] As shown in Figure 5As shown, the cutting support frame 71 is U-shaped, with the opening side of the cutting support frame 71 facing the turntable 3. When the diamond cutting wire rotates at high speed, it is used to cut the workpiece on the turntable 3.

[0037] like Figure 6 and 7 As shown, the tension wheel 74 is mounted on the tension wheel 74 shaft, and the tension wheel 74 shaft is mounted to the tension block through the bearing seat 82. A tension slide rail 84 is provided on one side of the cutting support frame 71. The cutting support frame 71 has a tension chamber 75. The tension slide rail 84 is fixed on the lower side of the tension chamber 75, and the tension wheel 74 is located below the tension chamber 75.

[0038] The tensioning block is slidably assembled with the tensioning slide rail 84, and is connected to the cylinder body of the cylinder 81. The tensioning block consists of two parts: the upper part is a U-shaped plate 832 with an opening facing downwards, and the lower part is a convex shape. The U-shaped plate 832 is bolted to the upper side of the slider 831. The slider 831 is slidably assembled with the tensioning slide rail 84.

[0039] The bearing housing 82 is located within the space of the U-shaped plate 832, and the upper side of the U-shaped plate 832 is connected to the cylinder body of the cylinder 81. The bearing housing 82 is inserted into the slider 831 and fixed thereto.

[0040] Cylinder 81 is located in tension chamber 75. One end of the telescopic rod of cylinder 81 is fixed to the cutting support frame 71, i.e., fixed to the inner wall of tension chamber 75. The telescopic rod of cylinder 81 moves in the left-right direction to tension tension wheel 74. When cylinder 81 moves in the left-right direction, it drives tension wheel 74 to move synchronously, changing the distance between tension wheel 74 and drive wheel. During normal operation, tension wheel 74 is in a tensioned state; when it is necessary to replace the cutting wire, cylinder 81 is activated to release the tension of tension wheel 74, which allows for easy disassembly and reinstallation of the cutting wire.

[0041] During the cutting process, the cutting method can be selected according to the needs. First, the turntable 3 rotates continuously in a specific direction, i.e., continuous unidirectional rotation cutting. Second, the turntable 3 moves clockwise for a period and then rotates counterclockwise for a period, alternating between the two, i.e., oscillating cutting. Third, at the beginning of cutting the workpiece, continuous unidirectional rotation cutting is used with the turntable 3, and oscillating cutting is switched after the cutter reaches the specified depth. The rotation direction of the turntable 3 is selected according to the shape of the workpiece and the cutting depth, thus choosing different cutting modes. This improves cutting efficiency and avoids excessive contact area during diamond wire cutting, which can cause diamond wire fatigue. It also allows for sufficient cooling of the diamond wire and chip removal.
