DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a flange cutting machine capable of preventing debris from splashing, comprising a workbench 1, a top plate 4 and a cutting machine tool holder 501, a base 2 being fixed at the bottom of the workbench 1, a support frame 3 being fixed at the four corners of the workbench 1 and the base 2, a top plate 4 being fixed at the upper end of the support frame 3, side baffles 401 being rotatably connected to both sides of the top plate 4 through a rotating shaft, a connecting frame 402 being welded and fixed to the upper end of the side baffle 401, a cylinder 403 being movably connected between the top of the top plate 4 and the connecting frame 402, the workbench 1 being close to the top plate 4 Adjacent ends of the side baffle plate 401 are respectively provided with a feed port and a discharge port, and a hydraulic telescopic rod 5 is symmetrically installed on the lower side surface of the top plate 4 near the discharge port, and a cutting machine tool holder 501 is installed on the lower end of the hydraulic telescopic rod 5; a front baffle plate 404 for shielding the cutting machine tool holder 501 is welded to the edge of the side baffle plate 401 near the discharge port, and the side baffle plate 401 and the front baffle plate 404 are made of acrylic material to ensure that the side baffle plate 401 and the front baffle plate 404 are transparent and easy to observe, so that the staff can be blocked and protected on the outside of the baffle assembly.

[0027] In the specific implementation, the cylinder 403 is activated to contract to pull the connecting frame 402, so that the connecting frame 402 drives the side baffle 401 around the rotating shaft to flip and open laterally, so that the side baffle 401 drives the front baffle 404 to separate from the discharge port, so that the staff can place the rod-shaped blank for processing the flange on the workbench 1, and push the rod-shaped blank to the bottom of the cutting machine tool holder 501 as needed;

[0028] When it is necessary to process the rod-shaped blank, the connecting frame 402 is pushed by reverse starting the cylinder 403, so that the connecting frame 402 drives the side baffles 401 to flip in the opposite direction, so that the two groups of side baffles 401 can cover the two sides of the workbench 1, and then the two groups of front baffles 404 are used to cover the discharge port position of the workbench 1; when the hydraulic telescopic rod 5 drives the cutting machine tool holder 501 to move downward, it can drive the blade in the cutting machine tool holder 501 to rotate at a high speed to complete the cutting of the rod-shaped blank, which is convenient for the preliminary cutting processing of the flange blank. When cutting the flange blank at a high speed, the two groups of closed side baffles 401 and the front baffle 404 can prevent the cutting waste from splashing.

[0029] See also Figure 2-Figure 5 A buffer port 101 is provided on the surface of the workbench 1 near the discharge port, a material drop channel 12 is fixed on the lower side of the workbench 1 near the buffer port 101 , and a waste tray 13 is provided on the lower side of the material drop channel 12 .

[0030] During specific implementation, when the cutting machine tool holder 501 moves downward to complete the cutting of the flange blank, the blade of the cutting machine tool holder 501 will enter the buffer port 101 to protect the blade. When waste chips are generated by cutting, the waste chips will enter the blanking channel 12 along the buffer port 101 and be collected through the waste tray 13 at the bottom of the blanking channel 12 for convenient centralized processing.

[0031] See also Figure 2 , Figure 4 and Figure 5 A material receiving hopper 11 is installed on one side of the workbench 1 close to the buffer port 101 .

[0032] In specific implementation, when the flange blank is cut, the cut blank will fall into the receiving hopper 11 and be guided out through the inclined inner wall of the receiving hopper 11. There is no need for personnel to manually take the material from the lower side of the cutting machine tool holder 501, thereby ensuring that the personnel's hands are protected.

[0033] See also Figure 2-Figure 4Slide sleeves 502 are fixed on both sides of the cutting machine tool holder 501, and the slide sleeves 502 are slidably connected to the support frame 3 at the discharge port of the workbench 1. When the cutting machine tool holder 501 moves up and down, the sliding of the slide sleeves 502 and the support frame 3 ensures that the cutting machine tool holder 501 has the characteristics of stability and anti-shaking when moving.

[0034] See also Figure 1-Figure 6 The surface of the workbench 1 is provided with a plurality of parallel slide grooves 6, in which a clamp seat 7 slides, and a V-shaped clamping opening is provided between two adjacent clamp seats 7;

[0035] A fixing column 8 is welded to the bottom of the clamp seat 7, and the fixing column 8 passes through the slide groove 6. A threaded hole is opened on the surface of the lower end of the fixing column 8. The fixing column 8 is connected to the bidirectional threaded rod 9 through the threaded hole. The middle part of the bidirectional threaded rod 9 is movably connected to the base 2 through a bearing, and a turntable 10 is fixed to one end of the bidirectional threaded rod 9.

[0036] In specific implementation, when placing the rod-shaped blank, the rod-shaped blank is placed between two adjacent clamping seats 7, and the bidirectional threaded rod 9 is rotated by the turntable 10, so that the bidirectional threaded rod 9 and the fixed column 8 are threadedly transmitted, thereby ensuring that the fixed column 8 and the clamping seat 7 on the same group of bidirectional threaded rods 9 can drive the two clamping seats 7 to move closer to or away from each other along the slide groove 6. When the two clamping seats 7 are close to each other, the rod-shaped blank can be stably clamped by the V-shaped clamp. Since multiple clamping components are arranged on the workbench 1, it is ensured that the cutting machine has a stable clamping effect when cutting the flange blank.

[0037] To summarize, the rod-shaped blank for processing the flange is placed on the workbench 1, and the bidirectional threaded rod 9 is rotated by the turntable 10, so that the bidirectional threaded rod 9 and the fixed column 8 are threadedly transmitted, thereby driving the two clamping seats 7 to move closer to each other so that the rod-shaped blank can be stably clamped through the V-shaped clamp. When the hydraulic telescopic rod 5 drives the cutting machine tool holder 501 to move downward, the blade in the cutting machine tool holder 501 can be driven to rotate at a high speed to complete the cutting of the rod-shaped blank.
