Fig. 1 is a schematic structural view of a bar cutting apparatus, and as shown in fig. 1, the bar cutting apparatus includes a frame 10, a pusher mechanism 20, a cutting mechanism 40, a holding device 30, and an auxiliary mechanism 50. The pushing rod mechanism 20 is used for pushing out the rod 60, the clamping device 30 is used for clamping and fixing the rod 60 during cutting, the cutting mechanism 40 is used for cutting the rod 60, and the auxiliary mechanism 50 is used for assisting in fixing the rod 60 during cutting and driving the rod 60 to rotate so as to improve the cutting efficiency.

The frame 10 is substantially frame-shaped, and the top surface has a mounting plane, and the above-mentioned push rod mechanism 20, cutting mechanism 40, clamping device 30 and auxiliary mechanism 50 are all mounted on the frame 10.

Fig. 2 is a schematic structural view of the pusher mechanism 20. In the present embodiment, the push rod mechanism 20 is disposed on the frame 10, and is used for pushing the rod 60 to move along the axial direction (i.e. the length direction of the rod 60). As shown in fig. 2, the push rod mechanism 20 includes a holder 21, a holder cylinder 22, a holder arm 23, a push rod cylinder 24, and a rod frame 25. The holder 21 has a substantially flat plate shape and is movably connected to the frame 10 along the length direction of the rod 60 by a slider and a slide rail. The clamping cylinder 22 is disposed on the clamping base 21, and the clamping arm 23 is connected to the clamping cylinder 22 to clamp the rod 60. In this embodiment, the push rod mechanism 20 can push two rod members 60 simultaneously, the number of the clamping cylinders 22 is two, the number of the clamping arms 23 is two, each clamping arm 23 has two clamping protrusions 231 with the same phase, and the clamping protrusion 231 of each clamping arm 23 is opposite to the clamping protrusion 231 of the other clamping arm 23. When the clamp cylinders 22 are simultaneously contracted, the clamp projection 231 of one clamp arm 23 moves away from the clamp projection 231 of the other clamp arm 23; when the chucking cylinders 22 are simultaneously extended, the chucking protrusion 231 of one chucking arm 23 is approached with respect to the chucking protrusion 231 of the other chucking arm 23 to chuck the rod 60.

The rod 60 moves by gravity to fall between the holding projections 231 and then the holding cylinder 22 is simultaneously extended so that the holding projections 231 come close to hold the rod 60. Then, the push rod cylinder 24 extends to drive the clamping seat 21 to move along the length direction of the rod 60, so as to move the rod 60 along the axial direction to push out the rod 60.

In use, the two ends of the rod 60 are placed in the opening grooves 251, so that the rod 60 is vertically stacked in the opening grooves 251. After the rod 60 at the lowest layer is pushed out for cutting, the rod 60 at the upper layer automatically falls by one layer under the action of self weight, so that the function of automatically supplementing the rod 60 and automatically realizing continuous cutting is realized.

Fig. 5 is a schematic structural view of the holding device 30. As shown in fig. 1 and 5, the clamping device 30 includes a fixing seat 31, a guide member 32, and a clamping member 33. The fixing seat 31 is connected to the frame 10, in this embodiment, the fixing seat 31 is fixedly connected between the cutting mechanism 40 and the pushing rod mechanism 20 of the frame 10, and the fixing seat 31 has a through hole. The guide member 32 is provided with guide holes 321 penetrating through both ends, the guide member 32 is connected to the fixing base 31, and the guide holes 321 extend in the length direction of the rod member 60. In the present embodiment, the guide 32 is rotatably provided in the through hole of the holder 31 and is rotatable along the central axis. The number of the clamping pieces 33 is plural, and the clamping pieces are arranged along the circumferential direction of the guide hole 321. The middle of the clamping member 33 is hinged to the guide member 32 at a hinge point 332, one end is connected to the guide member 32 by an elastic member 331, and the distance between the ends of the clamping member 33 is slightly smaller than the diameter of the guide hole 321. The clamping member 33 is pressed when the rod member 60 is inserted into the guide hole 321, so that the clamping member 33 clamps the rod member 60 by the elastic force of the elastic member 331.

Fig. 6 is a schematic structural diagram of the cutting mechanism 40, and as shown in fig. 6, the cutting mechanism 40 includes a cutting base 43, a cutting wheel 42, a cutting motor 41, and a cutting cylinder 44.

The cutting motor 41 is disposed on the cutting base 43 and connected to the cutting wheel 42 for driving the cutting wheel 42 to rotate to cut the rod 60. The cutting cylinder 44 has one end connected to the frame 10 and the other end connected to the cutting block 43 to push and pull the cutting block 43.

Fig. 7 is a schematic structural view of the assist mechanism 50. As shown in fig. 7, the auxiliary mechanism 50 includes a support member 51, a rotating shaft 52, a driving motor 53, and a push-pull cylinder 54. The supporting member 51 is movably connected to the frame 10 along the length direction of the rod member 60. In this embodiment, the supporting member 51 has a blocking surface facing the end of the rod member 60 for blocking the pushing of the push rod mechanism 20. The shaft 52 is movably connected to the supporting member 51, and has an end portion extending out of the supporting member 51 toward the rod 60. When the pushing rod mechanism 20 pushes out the rod 60, the end of the rod 60 is sleeved on the end of the rotating shaft 52 to support the rod 60 to rotate during cutting. The driving motor 53 is connected to the rotating shaft 52 to drive the rotating shaft 52 to rotate, so that the rotating shaft 52 drives the rod 60 to rotate. The push-pull cylinder 54 is connected to the support member 51 for pushing and pulling the support member 51. In use, the support 51 may be moved by the push-pull cylinder 54 so that the distance between the blocking face and the side of the cutting wheel 42 is equal to the cutting length. When the bar 60 is pushed to the end abutting against the rotating shaft 52, the driving motor 53 rotates the rotating shaft 52, so as to rotate the bar 60, so that the cutting wheel 42 can cut the bar 60.

The bar cutting method implemented by applying the above-described bar cutting apparatus is described in detail below.

First, both ends of the bar 60 to be cut are respectively put into the bar frame 25 so that the bars 60 are stacked in the vertical direction within the bar frame 25.

Then, after the clamping cylinder 22 of the push rod mechanism 20 drives the clamping arm 23 to clamp the rod 60, the push rod cylinder 24 pushes the clamping seat 21 to move, so that the rod 60 is moved along the axial direction until the end of the rod 60 is sleeved on the rotating shaft 52 of the auxiliary mechanism 50. At this time, the rod 60 abuts against the clamping member 33 of the clamping device 30, so that the clamping member 33 clamps the rod 60 under the elastic force of the elastic member 331.

Finally, the cutting cylinder 44 of the cutting mechanism 40 pushes the cutting block 43 to move and the cutting motor 41 drives the cutting wheel 42 to rotate, so that the cutting wheel 42 contacts the rod 60 to cut the rod 60. Before cutting, the driving motor 53 of the auxiliary mechanism 50 drives the rotating shaft 52 to rotate and the rotation direction of the rod 60 is opposite to the rotation direction of the cutting wheel 42, so that the rod 60 is driven to rotate to facilitate the cutting wheel 42 to cut the rod 60.
