Technical Field

[0001] This utility model relates to the field of screw wire cutting technology, specifically a screw raw material punching and segmenting mechanism. Background Technology

[0002] Screws are usually made from coiled round steel (wire). The diameter of this wire is similar to the nominal diameter of the screw (e.g., M6 screws use about 6mm wire). During production, the coiled wire is straightened by a straightening machine into a continuous straight line. Then, the feeding mechanism pushes the wire to the cutting and segmenting mechanism according to the screw requirements for cutting. After being supplied to the subsequent production process, the screw is made through multiple processing steps.

[0003] In actual processing, the existing segmentation mechanism lacks a real-time calculation mechanism. It only has separate cutting and segmenting components and cannot directly determine the number of segments in each batch to quickly meet statistical needs. It also requires the cumbersome transfer of products to additional calculation equipment.

[0004] Based on this, the present invention designs a screw raw material punching and segmenting mechanism to solve the above problems. Summary of the Invention

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a screw raw material punching and segmenting mechanism, including: a mounting plate 1 and a main plate 5; a base 2 and a slide rail 3 are fixedly connected to the outer wall of the mounting plate 1 respectively, and a slider 4 is fixedly connected to the outer wall of the main plate 5, with one end of the slider 4 slidably connected to the slide rail 3; Multiple adjusting screw holes 10 are sequentially opened on the outer wall of the base 2. A connecting arm 11 is provided on the outer wall of the base 2. A contact sensor 13 is fixedly connected to one end of the connecting arm 11. A conveying sleeve 8 is detachably connected to the outer wall of the base 2. The sensing end of the contact sensor 13 faces the discharge end of the conveying sleeve 8 and is aligned with its axis. One end of the main board 5 is fixedly connected to the tool holder 6, and the other end is fixedly connected to the baffle 16. An infrared counting sensor 14 is fixedly connected to the outer wall of the mounting plate 1. An auxiliary bending plate 15 is fixedly connected to the sensing end of the infrared counting sensor 14. A monitoring space is left between the auxiliary bending plate 15 and the sensing end of the infrared counting sensor 14, and the monitoring space is located in the straight moving path of the baffle 16. The mounting plate 1 serves as the overall base, connecting and fixing the slide rail 3, base 2, and other basic structures. The main board 5, through the cooperation of the slider 4 and the slide rail 3, achieves linear sliding. The blade holder 6 is fixedly connected to the front end of the main board 5 and is used to install the blade 7 for cutting raw materials. The baffle 16 at the rear of the main board 5 can block the infrared sensor during reciprocating motion, automatically recording the number of cuts for easy counting and statistics. The contact sensor 13 is installed on the connecting arm 11 to sense the arrival of the raw material in the conveying sleeve 8, which is used to determine whether the wire has been delivered to the correct position, ensuring accurate cutting each time.

[0017] In a further preferred embodiment, a servo motor 17 is also fixedly mounted on the mounting plate 1. The output shaft of the servo motor 17 is connected to an eccentric block 18. The eccentric block 18 is hinged to the main board 5 through a linkage rod 19, so as to drive the main board 5 to reciprocate along the slide rail 3 to realize the cutting action. The servo motor 17 drives the eccentric block 18 to rotate. When the eccentric block 18 rotates eccentrically around the axis, it drives the linkage rod 19 to swing up and down. The linkage rod 19 is hinged to the main board 5, so that the main board 5 performs reciprocating linear motion, thereby driving the blade 7 to cut. The simple eccentric rotation is converted into linear motion, and the structure is compact.

[0018] More preferably, a blade 7 is detachably connected to the front end of the blade holder 6. The blade 7 is arranged vertically downward and faces the discharge port of the conveying sleeve 8 to achieve precise cutting of the output raw material. The front end of the cutter holder 6 is equipped with a detachable blade 7, which is arranged vertically downward. The blade 7 is aligned with the discharge port of the conveying sleeve 8 to directly punch the wire. The vertical punching method ensures a neat cut and precise alignment with the discharge port, thereby improving cutting accuracy.

[0019] A further preferred embodiment has a connecting plate on the outer wall of the conveying sleeve 8, and a first bolt 9 is threadedly connected between the connecting plate and the base 2 to enable the detachable installation of the conveying sleeve 8. The conveying sleeve 8 is equipped with a connecting plate, which is threadedly locked to the base 2 by the first bolt 9, so that the conveying sleeve 8 can be detachably connected to the overall structure, adapting to different specifications of wires. Only the conveying sleeve 8 needs to be replaced.

[0020] More preferably, a second bolt 12 is threaded between the connecting arm 11 and an adjusting screw hole 10 of the base 2 to achieve adjustable installation of the contact sensor 13. A contact sensor 13 is installed on the connecting arm 11. It is threadedly locked to the base 2 adjustment screw hole 10 by the second bolt 12, so that the position can be finely adjusted to adapt to different conveying sleeve 8 lengths and wire specifications.

[0021] One specific application of this embodiment is as follows: During installation, the conveying sleeve 8 is threadedly connected to the base 2 through the connecting plate and aligned with the feeding direction; the position of the contact sensor 13 is adjusted so that its sensing end is directly opposite the sleeve outlet, and the blade 7 is installed at the end of the blade holder 6 and the blade 7 screw is tightened. The blade 7 must be perpendicular to the outlet end of the conveying sleeve 8, while the auxiliary bending plate 15 maintains an appropriate gap with the infrared counting sensor 14 so that the baffle 16 of the main board 5 can block the sensing light path once for each punching motion, so as to achieve one count per cut; During operation, the wire is straightened by the straightening machine and then pushed into the conveying sleeve 8 by the feeding mechanism. After sensing the position, the contact sensor 13 outputs a signal, and the contact sensor 13 drives the motor to start punching. After each punching, the baffle 16 blocks the light path of the infrared sensor to complete one count. This infrared signal can be fed back to the main control system in real time to realize automatic accumulation of segment quantity and real-time counting to quickly determine the completion of the preset production process. The contact sensor 13 is fixedly installed at one end of the connecting arm 11 of the base 2, with its sensing end aligned with the discharge port of the conveying sleeve 8. It can be triggered by the front end of the screw material (such as wire) when it is pushed to the predetermined cutting position, thus achieving accurate detection of the material feeding endpoint. This signal can be fed back to the main control system to determine whether the wire is in a state to be cut, thereby controlling the servo motor 17 to start the cutting action.
