Description

Technical Field

[0001] The present invention relates to the technical field of slotting machines, and more particularly to a bidirectional slotting machine for metal sheets capable of centrally processing debris. Background Art

[0002] The metal sheet processing process involves grooving the metal sheet, which requires the use of a metal sheet grooving machine. The metal sheet grooving machine can perform V-shaped grooves on stainless steel sheets, aluminum sheets, composite aluminum sheets, copper sheets and other metal sheets, making the radius of the edge arc of the workpiece after bending extremely small, meeting the special needs of high-end decoration in hotels, restaurants, restaurants, shopping malls, banks, airports and other places.

[0003] In the prior art, a bidirectional grooving machine for metal sheets achieves efficient grooving efficiency by the relative movement of two grooving cutters, thereby synchronously grooving from both sides of the metal sheet toward the center. Although this equipment can achieve a high grooving efficiency, chips are generated when the grooving cutters grooving the surface of the steel plate. Small chips can be driven out of the grooves as the grooving cutters move, but if the grooving depth is large, strip chips will be generated. Such strip chips cannot be driven out by the grooving cutters and will slide on the surface of the grooving cutters. Since the grooving is completed by the relative movement of the two grooving cutters, the strip chips will be clamped by the two grooving cutters when they are close to each other, causing a deviation in the movement stroke of the grooving cutters, and then causing a deviation in the grooving stroke, and may damage the grooving cutters.

[0004] Therefore, in order to solve the above problems, a metal sheet bidirectional slotting machine which can centrally process the debris is proposed. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a bidirectional grooving machine for metal sheets that can centrally process debris. The technical problem to be solved by the present invention is: when the grooving depth is large, the bidirectional grooving machine in the prior art will produce strip chips. Such strip chips cannot be driven out by the grooving cutter and will slide on the surface of the grooving cutter along the surface of the grooving cutter. Since the grooving is completed by relative motion between the two grooving cutters, the strip chips will be clamped by the two grooving cutters when the two grooving cutters are close to each other, causing the movement stroke of the grooving cutters to deviate, thereby causing the planing stroke to deviate, and may cause damage to the grooving cutters.

When the cutter mounting seat 10 moves, the roller 20 alternately rolls on the upper surface of the fixing plate 15 and the inner wall of the notch groove 14. Specifically, when the roller 20 rolls to the upper surface of the fixing plate 15, the roller 20 is subjected to the pulling force of the tension spring 34 on the sliding sleeve 37, so that the sliding sleeve 37 drives the connecting rod 17 and the connecting arm 24 to move upward, so that the cutter 38 is retracted into the cutter mounting seat 25. As the cutter mounting seat 10 continues to move, when the roller 20 rolls from the upper surface of the fixing plate 15 to the inner wall of the notch groove 14, the tension spring 34 will pull the connecting rod 17 and the connecting arm 24 to move upward. The sliding sleeve 37 moves downward, thereby driving the connecting rod 17 and the connecting arm 24 to move downward, so that the cutter 38 moves from the cutter mounting seat 25 into the collecting bin 9, and the cutter 38 cuts the strip chips entering the collecting bin 9, thereby cutting off the strip chips.

[0038] A sliding rod 26 is horizontally penetrated on the outer wall of one side of the collecting bin 9 away from the tool mounting seat 10. The sliding rod 26 slides freely on the tool mounting seat 10. A sliding pin 31 is horizontally penetrated on the end of the sliding rod 26. A strip plate 33 is fixedly connected to the surface of the baffle 27. A sliding groove 32 for the sliding pin 31 to engage is opened on the outer wall of the strip plate 33.

A spring 30 is sleeved on the sliding rod 26. The two ends of the spring 30 in the elastic force direction elastically press against the stop ring 29 and the side wall of the collecting bin 9 respectively and one by one. When the two planing knives 8 move close to each other to carry out the planing operation When the tool mounting seat 10 moves toward the outside of the lifting workbench 2, the end of the sliding rod 26 will contact the limit plate 5, so that the collection bin 9 and the sliding rod 26 move relative to each other, and the stop ring 29 compresses the spring 30, and the sliding pin 31 slides in the sliding groove 32 in the opposite direction, thereby driving the baffle 27 to flip downward, so that the lower side of the collection bin 9 is open, and the strip chips in the collection bin 9 slide along the upper surface of the baffle 27 into the collection groove 3, completing the collection of the strip chips.

[0039] Working principle of the present invention:

[0040] When the feeding unit 7 drives the two tool connecting seats 11 to move relatively close to each other to perform the feeding action, the movement of the tool connecting seat 11 will synchronously drive the tool mounting seat 10 to move, so that the planing knife 8 planing grooves the metal plate placed on the top of the lifting workbench 2, and the tool mounting seat 10 will make the gear 16 and the rack plate 4 mesh and rotate when moving horizontally, so as to rotate the driving shaft, so that the shaft drives the pressing conveyor belt 13 to rotate, so that the pressing conveyor belt 13 rotates counterclockwise (refer to Figure 2 ), when the pressing conveyor belt 13 rotates counterclockwise, it bites the end of the strip chips generated by the planing cutter 8 during planing, so that the strip chips are bitten between the pressing conveyor belt 13 and the chip sliding inclined surface 21, and at the same time, the pressing conveyor belt 13 generates friction force on the strip chips, so that the strip chips slide along the chip sliding inclined surface 21 to the chip penetration port 22;

[0041] The strip-shaped chips enter the transition bin 28 from the chip passing port 22, and then enter the collection bin 9 from the transition bin 28. As the tool mounting seat 10 moves, the roller 20 alternately rolls on the upper surface of the fixed plate 15 and the inner wall of the notch groove 14. Specifically, when the roller 20 rolls to the upper surface of the fixed plate 15, it is pulled by the tension spring 34 on the sliding sleeve 37, so that the sliding sleeve 37 drives the connecting rod 17 and the connecting arm 24 to move upward, so that the cutter 38 is retracted into the cutter mounting seat 25. As the tool mounting seat 10 continues to move, when the roller 20 rolls from the upper surface of the fixing plate 15 to the inner wall of the notch groove 14, the tension spring 34 pulls the sliding sleeve 37 to move downward, thereby driving the connecting rod 17 and the connecting arm 24 to move downward, so that the cutter 38 moves from the cutter mounting seat 25 to the collecting bin 9, and then the cutter 38 cuts the strip chips entering the collecting bin 9, and then the strip chips are cut off, and the cut strip chips remain in the collecting bin 9;

[0042] After a single grooving operation is completed, the feed unit 7 drives the tool mounting seat 10 to move in the opposite direction, that is, when the tool mounting seat 10 moves toward the outside of the lifting workbench 2, the end of the sliding rod 26 will contact the limit plate 5, so that the collecting bin 9 and the sliding rod 26 move relative to each other, and the retaining ring 29 compresses the spring 30. At the same time, the sliding pin 31 slides in the opposite direction in the sliding groove 32, thereby driving the baffle plate 27 to flip downward, so that the lower side of the collecting bin 9 is open, and the strip chips in the collecting bin 9 slide along the upper surface of the baffle plate 27 into the collecting groove 3, completing the collection operation of the strip chips.
