[0025] A preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 4 The utility model provides a rod cutting device, which includes a support frame 1, a sealed cutting mechanism 2 and a waste chip collecting mechanism 3 arranged on the support frame 1. The sealed cutting mechanism 2 ensures that the part of the rod to be cut is located in a sealed environment. The waste chip collecting mechanism 3 is connected to the sealed cutting mechanism 2, which ensures that the waste chips generated during cutting will not splash outside the sealed cutting mechanism 2 while ensuring that the waste chips are collected in a centralized manner.

[0027] Specifically, the support frame 1 is a "]"-shaped structure, including two upper horizontal plates 11 and a lower horizontal plate 12 arranged opposite to each other in the upper and lower directions, and a vertical plate 13 arranged between the upper horizontal plate 11 and the lower horizontal plate 12 in the vertical direction. In order to ensure that the support frame 1 remains balanced, the support frame 1 is fixedly arranged on the base 5 through the lower horizontal plate 12; the sealed cutting mechanism 2 is arranged on the side of the vertical plate 13 facing the opening, and includes a cutting box 21 arranged on the vertical plate 13, and a cutting tool 22 arranged in the cutting box 21. A through hole 23 matching the diameter of the rod material is provided on the cutting box 21 in the horizontal direction, so that the rod material passes through the cutting box 21 along its axial direction, and the waste chips generated during the cutting process fall to the bottom of the cutting box 21; the waste chip collection mechanism 3 includes a waste chip collection assembly 31 arranged on the lower horizontal plate 12, and a material guide pipe 32 connecting the waste chip collection assembly 31 with the cutting box 21, so that the waste chips generated during cutting are guided from the cutting box 21 to the waste chip collection assembly 31 through the material guide pipe 32.

[0028] Furthermore, the cutting box 21 includes an upper box body 211 and a lower box body 212. The upper box body 211 and the lower box body 212 are movably connected to the vertical plate 13 on one side thereof close to the vertical plate 13 through a bidirectional threaded rod 24. A driving motor 25 for driving the bidirectional threaded rod 24 to rotate is provided on the upper horizontal plate 11, so that the upper box body 211 and the lower box body 212 are relatively close to form a cutting box 21 with a sealed space, and the cutting tool 22 is arranged in the upper box body 211. Among them, the cutting tool 22 is a saw blade, which is mounted on the output shaft of the saw blade motor. The saw blade motor is fixedly connected to the inner upper wall surface of the upper box body 211, so that the cutting tool 22 is rotatably arranged in the upper box body 211. The saw blade motor drives the saw blade to rotate and can move up and down to cut the bar material to be cut, which is an existing conventional setting, and this application will not elaborate on it.

[0029] Furthermore, a slide groove 131 is opened on the vertical plate 13 in the vertical direction, and the bidirectional threaded rod 24 is rotatably arranged in the slide groove 131, and its upper end passes through the upper horizontal plate 11 and is connected to the output shaft of the driving motor 25; the upper box body 211 and the lower box body 212 are respectively provided with sliders 213 matching the slide groove 131, and the two sliders 213 are respectively provided with internal threads matching the upper end thread and the lower end thread of the bidirectional threaded rod 24. It can be understood that the bidirectional threaded rod 24 has an upper thread section and a lower thread section, wherein the upper box body 211 is connected to the upper thread section through the internal thread on the slider 213, and the lower box body 212 is connected to the lower thread section through the internal thread on the slider 213. When the driving motor 25 drives the bidirectional threaded rod 24 to rotate, the two sliders 213 thereon are driven to move relatively close or relatively far away at the same time, thereby driving the upper box body 211 and the lower box body 212 to be relatively close to form a sealed cutting box 21 or relatively far away to place the bar to be cut on the lower box body 212 and supported by the arc grooves 214 on both sides. In addition, the upper box body 211 and the lower box body 212 are slidably matched in the slide groove 131 through the slider 213, so that the upper box body 211 and the lower box body 212 can maintain stable movement in the vertical direction and ensure the sealing formed by the cutting box 21. In addition, by arranging the upper box body 211 and the lower box body 212 to move relatively synchronously, the time for opening the cutting box 21 or forming a sealed space is shortened, thereby improving the cutting efficiency of the bar material.

[0030] Furthermore, arc grooves 214 are respectively provided on the two side walls of the upper box body 211 and the lower box body 212 along the axial direction of the bar material, so that the upper box body 211 and the lower box body 212 are relatively close to form a cutting box 21 with a through hole 23; arc support members 2121 are also respectively provided on the outer side surfaces of the two side walls of the lower box body 212. That is, arc grooves 214 are respectively recessed on the end surfaces of the relatively close side walls of the upper box body 211 and the lower box body 212. When the two end surfaces of the upper box body 211 and the lower box body 212 are relatively abutted, the two arc grooves 214 on the opposite side are spliced ​​to form a positioning hole matching the diameter of the bar material, and the two positioning holes are coaxially arranged to form a through hole 23 for horizontally arranging the bar material, and the part of the bar material extending outside the two sides of the cutting box 21 is supported by the arc support members 2121, so as to ensure that the bar material remains stable when being cut.

[0031] Furthermore, scrapers 26 are provided on the inner side surfaces of the two side walls of the cutting box 21 around the through hole 23, and the scrapers 26 are made of rubber material. That is, the scrapers 26 are arranged around the inner side of the through hole 23 of the cutting box 21, so that after the bar material is cut, when the operator pulls the bar material out of the cutting box from the two sides of the cutting box, the scrapers 26 can scrape off the waste chips adsorbed on the outer peripheral surface of the bar material and make it fall into the cutting box 21. At the same time, the scrapers 26 ensure the sealing of the cutting box 21 to prevent the waste chips from splashing out of the cutting box 21 through the through hole.

[0032] Furthermore, the inner side of the bottom of the lower box 212 is in a V-shaped funnel structure, and a discharge port 2122 connected to the inlet end of the guide tube 32 is provided at the bottom of the V-shaped funnel structure. The guide tube 32 is a telescopic tube that can be freely extended and retracted with the movement of the lower box 212. In addition, two limit plates 27 are arranged at intervals on the lower side surface of the bottom of the lower box 212 to prevent the lower box 212 from interfering with the waste collection assembly 31 when moving downward, and also to prevent the guide tube 32 and the waste collection assembly 31 from being squeezed.

[0033] Furthermore, the waste scrap collection assembly 31 includes a collection box 311 disposed on the lower horizontal plate 12, and a storage box 312 placed in the collection box 311 and movably connected to the collection box 311. The outlet end of the guide tube 32 passes through the top of the collection box 311 and is connected to the storage box 312. The storage box 312 and the collection box 311 are in a pull-out manner, and the collected waste scraps can be dumped by pulling out the storage box 312.

[0034] In the above structure, define Figure 2 This is the initial state of the device. The action process is as follows:

[0035] First, the operator places the bar to be cut on the lower box 212 so that the lower circumference of both ends of the bar is supported by the arc groove 214, and the electric control unit 4 controls the drive motor 25 to be energized to drive the bidirectional threaded rod 24 to rotate, and the upper box 211 and the lower box 212 are relatively close to form the cutting box 21, and at the same time, the arc groove 214 of the upper box 211 presses against the upper circumference of the bar to clamp and fix the bar, and the drive motor 25 is powered off;

[0036] Next, the electronic control unit 4 controls the cutting tool 22 to move downward and rotate to cut the bar material portion in the cutting box 21, and the waste chips generated during the cutting process are introduced into the discharge port 2122 from the bottom of the V-shaped funnel structure of the lower box 212, and are guided into the storage box 312 through the guide pipe 32;

[0037] Finally, the electronic control unit 4 controls the cutting tool 22 to reset, and the operator pulls the bar material out of the cutting box 21 from both ends of the cutting box 21, and the synchronous scraper 26 scrapes off the waste chips adsorbed on the bar material. Then the electronic control unit 4 controls the driving motor 25 to energize to drive the bidirectional threaded rod 24 to rotate, driving the upper box body 211 and the lower box body 212 to move away from each other and return to the initial state;

[0038] Repeat the above steps to complete the cutting of the bar.

[0039] In summary, the bar cutting device provided by the utility model arranges the cutting tool in the cutting box and provides a through hole on the cutting box for clamping the bar material, so that the waste chips generated during the cutting process are collected in the cutting box to prevent the waste chips from splashing out of the cutting box; by providing a waste chip collection mechanism connected to the cutting box, the centralized collection of waste chips is facilitated, the time for operators to clear and collect waste chips is reduced, and production efficiency is improved.
