Description

Technical Field

[0001] The utility model relates to the field of plate shearing machines, in particular to a novel numerically controlled plate shearing machine. Background Art

[0002] CNC shearing machine is a kind of equipment that automatically cuts metal plates through computer control system. Traditional CNC shearing machine usually includes shearing mechanism and CNC system. The operator inputs cutting parameters through CNC system, and the shearing mechanism performs cutting operation according to the instructions, so as to realize accurate and efficient processing of plates.

[0003] After research and analysis, it was found that the existing CNC shearing machines have some problems in feeding. Usually, the operator needs to manually place the sheet material to the feed end of the shearing machine. When the size of the sheet material is large, feeding is more difficult, and the manual feeding speed is also slow and inefficient. In addition, during the feeding process, the operator needs to be close to the shearing mechanism, which poses certain operational safety hazards. Therefore, the existing CNC shearing machines have some shortcomings in feeding, and further improvements are needed to improve feeding efficiency and ensure the safety of operation. Improvement measures can consider introducing an automatic feeding system to reduce the operator's manual intervention, thereby improving feeding efficiency and operational safety.

[0024] Embodiment 1:

[0025] Reference Figure 1-6A new type of CNC shearing machine includes: a shearing machine body, a feeding mechanism, and a CNC panel 5. The shearing machine body includes a frame 1, in which a shearing mechanism 2 and a base 3 are installed from top to bottom. The feeding mechanism includes two parallel U-shaped frames 6. A Y-direction plate 7 is slidably connected to the guide rail on the upper side of the U-shaped frame 6. An X-direction plate 8 is slidably connected to the guide rail on the upper side of the Y-direction plate 7. The X-direction plate 8 is L-shaped. The vertical section of the X-direction plate 8 is slidably connected to a Z-direction plate 9 through a guide rail. The Z-direction plate 9 is A mounting plate 10 is fixed to the bottom of the plate 9, a plurality of negative pressure suction cups 11 are fixed to the lower side of the mounting plate 10, a storage table 13 is placed directly below the negative pressure suction cup 11, a rack 1 61 is fixed to the upper side of the U-shaped frame 6, a rack 2 71 is fixed to the upper side of the Y-direction plate 7, a rack 3 91 is fixed to the outer surface of the Z-direction plate 9, and a driving mechanism 12 is fixed to the connecting parts between the Y-direction plate 7 and the rack 1 61, the horizontal section of the X-direction plate 8 and the rack 2 71, and the vertical section of the X-direction plate 8 and the rack 3 91.

[0026] The shearing mechanism 2 is provided with a hydraulic telescopic rod 21 and a connecting rod 1 22. The connecting rod 1 22 is rotatably connected to the upper part of the frame 1 and is provided with two of them. The upper part of one connecting rod 1 22 is hinged to the power output end of the hydraulic telescopic rod 21. The hydraulic telescopic rod 21 is rotatably connected to the upper side of the frame 1. A connecting rod 23 is hinged at the lower part between the two connecting rods 1 22. The connecting rod 23 and the two end hinge points of the connecting rod 1 22 are both rotatably connected to the connecting rod 3 24. A shearing piece 25 is vertically slidably connected to the guide rail in the frame 1. The shearing piece 25 is located at the lower side of the connecting rod 3 24 and is hinged to the bottom of the connecting rod 3 24.

[0027] like Figure 3 As shown, the operator can start the hydraulic telescopic rod 21 on the shearing mechanism 2 through the numerical control panel 5. When the movable end of the hydraulic telescopic rod 21 is extended, it will drive the connecting rod 1 22 to rotate. While the connecting rod 1 22 rotates, it can drive the shearing piece 25 to move vertically downward in the guide rail in the frame 1 through the cooperation of the connecting rod 2 23 and the connecting rod 3 24. The shearing piece 25 moves downward to shear the plate passing between the base 3 and the shearing piece 25.

[0028] A material discharging rack 4 is fixedly installed on one side of the frame 1 close to the feeding end of the plate, and the material discharging rack 4 is located between the shearing mechanism 2 and the base 3.

[0029] A plurality of rotating drums are evenly distributed on the unloading rack 4, and the rotating drums are parallel to the frame 1 and arranged in the horizontal direction.

[0030] Embodiment 2:

[0031] The difference between this embodiment and embodiment 1 is that:

[0032] The driving mechanism 12 is provided with a servo motor 121, and a power output end of the servo motor 121 is fixedly connected to a gear 122 via an output shaft. The gear 122 is respectively meshed with the rack 1 61, the rack 2 71, and the rack 3 91 at corresponding positions.

[0033] The upper side of the negative pressure suction cup 11 is fixedly connected to an external vacuum generator through a connecting pipe.

[0034] The numerical control panel 5 is fixedly mounted on the outer side of the frame 1 , and is electrically connected to the shearing mechanism 2 on the shearing machine body and the plurality of driving mechanisms 12 and the negative pressure suction cup 11 on the feeding mechanism.

[0035] Working principle: In the working state, the sheets to be cut are neatly placed on the storage table 13, such as Figure 4 , Figure 5 As shown, the operator can then start the driving mechanism 12 at the connection between the U-shaped frame 6 and the Y-axis plate 7 through the numerical control panel 5, and the servo motor 121 starts to drive the gear 122 to rotate. Since the gear 122 and the rack 161 are meshed with each other, the Y-axis plate 7 can be driven to move horizontally along the Y direction on the upper side of the U-shaped frame 6; similarly, when the driving mechanism 12 at the connection between the Y-axis plate 7 and the X-axis plate 8 is started, the X-axis plate 8 can move horizontally along the X direction on the upper side of the Y-axis plate 7; when the driving mechanism 12 at the connection between the X-axis plate 8 and the Z-axis plate 9 is started, the Y-axis plate 8 can move horizontally along the X direction on the upper side of the Y-axis plate 7; When the Z-direction plate 9 is moved up and down along the Z direction, i.e., the vertical direction, on the side of the X-direction plate 8, the negative pressure suction cup 11 on the lower side of the mounting plate 10 can be adjusted in the three directions of X, Y, and Z by the mutual cooperation after the above-mentioned multiple driving mechanisms 12 are started, until the negative pressure suction cup 11 moves to the top of the material storage table 13 and the negative pressure suction cup 11 and the upper surface of the sheet to be cut are attached to each other, and then the external vacuum generator is started through the numerical control panel 5, and the negative pressure adsorption force is generated on the negative pressure suction cup 11 by using the connecting pipe to suck up the sheet;

[0036] After the above-mentioned multiple driving mechanisms 12 are started and coordinated, the sucked sheet material can fall onto the surface of the unloading rack 4 after completing the movement adjustment in the three directions of X, Y and Z. Figure 1As shown, as the Y-plate 7 continues to move along the Y direction, that is, in the direction close to the frame 1, the sheet material will pass through the shearing mechanism 2 and the base 3 on the frame 1, and then the shearing mechanism 2 and the base 3 will cooperate to cut the sheet material. In this process, the corresponding processing operation can be completed only through the numerical control panel 5, and the operator does not need to hold the sheet material to the feeding end of the shearing machine body, which avoids close contact between the operator's limbs and the shearing mechanism 2 and protects the operator's safety. The driving mechanism 12 on the feeding mechanism cooperates with the Y-plate 7, the X-plate 8, and the Z-plate 9 to easily complete the adjustment of the position of the sheet material in the three directions of X, Y, and Z, which reduces the labor burden of the operator in feeding large sheets when cutting, saves manpower, and improves the efficiency of sheet shearing processing.
