Description

Technical Field

[0001] The utility model relates to the field of self-tapping screw processing, in particular to a self-tapping screw cold heading device. Background Art

[0002] A self-tapping screw is a screw with a special thread design that allows it to cut a threaded hole in the material being installed. This screw can be screwed directly into the material surface without having to use a drill to drill a hole first. Cold upsetting refers to a forging method that uses a mold to upset (usually partially upset) metal bars at room temperature. It is usually used to manufacture the heads of screws, bolts, rivets, etc., which can reduce or replace cutting processes.

[0003] After searching, the Chinese patent announcement number CN214290665U is found, which discloses a head cold heading device for the production and processing of carbon steel self-drilling screws. By setting a material receiving mechanism, after the cold heading processing of the carbon steel self-drilling screw head is completed, it slides down from the material receiving port, and the material bin performs preliminary collection of the carbon steel self-drilling screws. The upper part of the material bin is closed to prevent the carbon steel self-drilling screws from colliding with the inner wall of the material bin and popping out. When switching between the first material bin and the second material bin, the rotary valve is closed. At this time, the carbon steel self-drilling screws are collected by the material bin, and the support arm supports the support plate through the support seat. At the same time, the support plate realizes relative rotation through the rotating shaft. The support rotates, and at the same time, there is a damping effect between the support plate and the rotating shaft, so that the support plate remains relatively stable when not subject to external force. At this time, the support plate is rotated, and under the action of external force, the support plate rotates, so that the relative position of the first material box and the second material box changes. After the first material box and the second material box are switched, the rotary valve is opened. At this time, the first material box or the second material box continues to collect the carbon steel self-tapping screws to achieve the effect of continuous operation. At the same time, the weighing sensor transmits the collected carbon steel self-tapping screw weight information to the background, which is convenient for technicians to carry out quantitative processing of the carbon steel self-tapping screw heads.

[0004] However, since the position between the receiving port and the material box is relatively fixed, the self-tapping screws that fall into the material box are easily accumulated near the discharge port, resulting in uneven material discharge. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5As shown, a self-tapping screw cold heading device includes a cold heading machine 1. The cold heading machine 1 is a prior art and will not be described in detail. A discharge pipe 2 is bolted to one side of the cold heading machine 1. A control valve is provided in the discharge pipe 2. A base plate 3 is placed on the ground below the discharge pipe 2. A supporting plate 401 is slidably connected to the top of the base plate 3. A collection box 6 is placed on the top of the supporting plate 401. Two symmetrical slides are provided on the top of the base plate 3. A slider 402 is fixedly connected to the bottom of the supporting plate 401. The slider 402 is slidably connected in the slide. A spring 403 is connected between the slider 402 and the slide. A weighing sensor 5 is provided on the top of the supporting plate 401. The collection box 6 is located on the top of the weighing sensor 5. When the weighing sensor 5 reaches a certain value, the worker closes the control valve in the discharge pipe 2 and suspends unloading to facilitate the transportation of the self-tapping screws in the collection box 6.

[0026] A pull rod 9 is fixedly connected to the side of the supporting plate 401 away from the cold heading machine 1. The pull rod 9 is arranged in an L shape, and a through hole is provided on the pull rod 9. A limiting hole is provided on the top of the bottom plate 3. When the collection box 6 needs to be removed from the supporting plate 401, the supporting plate 401 is pulled away from the cold heading machine 1 through the pull rod 9 so that the through hole on the pull rod 9 coincides with the limiting hole. Then, the pin is inserted into the limiting hole through the through hole on the pull rod 9 to prevent the discharge pipe 2 from affecting the removal and placement of the collection box 6.

[0027] A limiting assembly is arranged between the collection box 6 and the supporting plate 401. The limiting assembly is used to limit the position of the collection box 6. The limiting assembly includes several limiting columns 701. The limiting columns 701 are fixedly connected to the top of the supporting plate 401. The limiting rings 702 are fixedly connected to both sides of the collection box 6. The limiting columns 701 are located in the limiting rings 702. The limiting rings 702 slide up and down along the limiting columns 701.

[0028] A power assembly is provided on the side of the cold heading machine 1 close to the collection box 6. The power assembly is used to drive the collection box 6 to perform reciprocating motion. The power assembly includes two mounting plates 801 bolted to the side wall of the cold heading machine 1. The two mounting plates 801 are arranged front and back. The front side bolts of the front mounting plate 801 are connected to a rotating motor 802. The output end of the rotating motor 802 is connected to a rotating shaft 803 through a coupling. The rotating shaft 803 is rotatably connected between the two mounting plates 801. Two cams 804 are fixedly connected to the rotating shaft 803. The limit assembly is located between the two cams 804 to avoid affecting the rotation of the cam 804. Start the rotating motor 802, and the rotating motor 802 drives the rotating shaft 803 to drive the cam 804 to rotate.

[0029] Working principle: After the self-tapping screw head is cold-forging through the cold heading machine 1, it slides down from the discharge pipe 2 and falls into the collection box 6. During the processing, the rotating motor 802 is started, and the rotating motor 802 drives the rotating shaft 803 to drive the cam 804 to rotate. When the tip of the cam 804 contacts the collection box 6, the cam 804 drives the collection box 6 to move away from the cold heading machine 1, and the spring 403 is compressed. When the tip of the cam 804 moves away, the supporting plate 401 and the collection box 6 are reset under the action of the elastic force of the spring 403, so that The collecting box 6 is constantly moving, so that the self-tapping screws fall evenly into the collecting box 6. Moreover, the collecting box 6 generates a certain vibration while performing reciprocating motion, so that the self-tapping screws in the collecting box 6 are more evenly distributed. When the weighing sensor 5 reaches a certain value, the worker closes the control valve in the discharge pipe 2, and then uses the pull rod 9 to pull the supporting plate 401 away from the cold heading machine 1. After pulling to a certain position, the pull rod 9 is fixed to the bottom plate 3 by the pin, and then the collecting box 6 is pulled upward to separate the collecting box 6 from the supporting plate 401.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
