Technical Field

[0001] This utility model relates to the field of bar cutting technology, and in particular to a metal bar slitting device. Background Technology

[0002] Bar stock refers to round or polygonal long rods of material with a certain length, as opposed to sheet metal and other profiles. Bar stock is generally not a casting but a raw material for forgings. It is mostly produced by stretching or extruding through a die, and can also be machined. Therefore, bar stock cutting equipment is needed in the bar stock processing process.

[0003] Chinese Patent No. CN220462479U discloses a metal bar slitting device, including a base, a placement seat fixedly connected to one side of the top of the base, a pushing mechanism fixedly connected to the top of the base, and a lifting mechanism fixedly connected to one end of the base. The lifting mechanism includes a first connecting sleeve, one end of which is fixedly connected to one end of the base, and a bracket fixedly connected to the end of the first connecting sleeve facing away from the base. A second connecting sleeve is connected to one end of the bracket. Round rods are movably sleeved on the inner walls of both the first and second connecting sleeves. A lever frame is fixedly connected to one end of the two opposite faces of the round rods. A fixing plate and a connecting rod are fixedly connected to the upper parts of both ends of the lever frame, respectively. By setting up the lifting mechanism, the device can be fixed during metal bar slitting. By setting up the pushing mechanism, the device can be conveniently pushed to improve the efficiency of the metal bar slitting device.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing metal bar cutting devices cannot automatically fix the metal bars before cutting, which requires workers to hold the metal bars during cutting. This not only increases the workload but also easily causes harm to workers during cutting. Furthermore, the length of the metal bars to be cut cannot be adjusted according to the needs, resulting in poor applicability. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to automatically fix the metal rod before cutting and adjust the length of the metal rod to be cut, and to propose a metal rod cutting device.

[0006] The technical solution of this utility model: A metal bar cutting device, including a support, a cutting table disposed on the top of the support, and an insertion tube disposed on the top of the cutting table; further comprising: A distance-fixing mechanism is located on the top of the slitting table and is used to adjust the length of the metal bar to be cut. The cutting and fixing mechanism is located on the top of the slitting table and outside the distance fixing mechanism. It is used to clamp and fix metal bars of different sizes before slitting. The connecting plate is mounted on the cutting and fixing mechanism. The side of the connecting plate is rotatably equipped with a gripper, and the side of the gripper is equipped with a spring. The end of the spring away from the gripper is connected to the connecting plate. There are two grippers symmetrically arranged about the connecting plate. The grippers are pressed against the metal bar by the rotation of the two grippers and the compression of the spring, thereby clamping metal bars of different sizes.

[0007] Preferably, it also includes a collection component, which includes a collection box, a pull ring, a cone-shaped platform, and a divider. The collection box is slidably positioned inside the cutting table, the pull ring is positioned outside the collection box, the conical platform is positioned inside the collection box and located at the center, and the partition plate is positioned at the bottom of the collection box.

[0009] Preferably, the cutting and fixing mechanism includes a cutting component and a fixing component; The cutting assembly is located on top of the slitting table and is used to slit metal bars. The fixing component is located on the side of the cutting component and is used to fix and clamp the metal bar before the cutting component cuts the metal bar.

[0010] Preferably, the cutting assembly includes a mounting bracket, a cylinder, a push rod, a cutting housing, and a motor; The mounting bracket is located on the top of the slitting table, the cylinder is located on the top of the mounting bracket, the push rod is located at the output end of the cylinder, the cutting shell is located at the bottom of the push rod, the motor is located on the side of the cutting shell, the output end of the motor is equipped with a rotating shaft, and the outside of the rotating shaft is equipped with a slitting blade.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: 1. Through the setting of the cutting and fixing mechanism, the cylinder drives the pressing table to squeeze the power table, thereby clamping the metal bar. At the same time, the cylinder and motor drive the slitting blade to cut the metal bar. This can avoid the bar shaking during cutting, which will cause the cut to deviate and the size error. It ensures that the bar is restored to a straight state before cutting, significantly improving the cutting accuracy. The stable clamping can effectively absorb vibration, ensure a smooth cut, reduce the appearance of burrs, and also quickly adapt to size, reduce manual intervention, shorten changeover time. Clamping and cutting can be completed by the operation of the cylinder alone, significantly reducing the risk of accidents.

[0013] 2. By setting up a distance fixing mechanism, pulling the pull rod drives the distance fixing plate to slide on the straight slide rail. After moving to the appropriate position, it is fixed by the positioning rod, thereby controlling the length of the metal bar to be cut. This allows for length switching to be completed within seconds by moving the position of the distance fixing plate on the straight slide rail, significantly reducing downtime. At the same time, it can easily handle small batch orders without the need to customize special tooling for each length, reducing inventory pressure and avoiding material waste caused by cutting errors.

Then, the pull rod 506 is released, and the positioning rod 505 is engaged in the positioning hole 503 at that position under the action of the spring 507, thus completing the fixing.

[0019] Example 2 like Figure 4As shown, this utility model proposes a metal bar cutting device. Compared with Embodiment 1, this embodiment details the structure of the cutting and fixing mechanism.

[0020] The cutting and fixing mechanism includes a cutting component and a fixing component; the cutting component is located on the top of the slitting table 2 and is used to cut the metal bar; the fixing component is located on the side of the cutting component and is used to fix and clamp the metal bar before the cutting component cuts the metal bar.

The output end of the motor 605 is provided with a rotating shaft 606, and a slitting blade 607 is provided on the outer side of the rotating shaft 606. When the motor 605 is started, the motor 605 drives the slitting blade 607 to rotate through the rotating shaft 606. Then, the cylinder 602 is started, and the cylinder 602 drives the slitting blade 607 to move up and down through the push rod 603, thereby cutting the metal bar. The fixing assembly includes a pressing frame 608, a pressing table 609, a vertical plate 610, and a sliding rod 611.

Then, the metal bar is passed through the insertion tube 3 and the end is pressed against the spacer plate 502. The cylinder 602 and the motor 605 are started. The cylinder 602 drives the pressing table 609 to move through the push rod 603. After the pressing table 609 contacts the power table 614, it drives the power table 614 to move. The power table 614 drives the sliding rod 611 to slide on the vertical plate 610. The sliding rod 611 drives the telescopic rod 612 and the connecting plate 615. When the side of the connecting plate 615 contacts the outside of the metal bar, the gripper 616 rotates under the action of the spring 617, so that the gripper 616 fits against the metal bar, thus stably clamping metal bars of different sizes. After clamping, the cylinder 602 continues to drive the push rod 603 to move. At this time, the gripper 616 always keeps close to the metal bar under the action of the spring 613 and the telescopic rod 612. The motor 605 drives the slitting blade 607 to rotate through the rotating shaft 606. The push rod 603 drives the slitting blade 607 to move downward to cut the metal bar. The cut metal bar falls into the collection box 401. The conical platform 403 guides the metal bar to roll to the bottom. The partition plate 404 keeps the metal bars straight when stacked.
