Description

Technical Field

[0001] The utility model relates to the technical field of cold drawing production, in particular to a steel wire cold drawing structure with anti-breaking function. Background Art

[0002] Cold drawn steel is a processing technology for steel, which refers to various cold drawn steels produced by cold drawing method. The characteristics of cold drawn steel are: high precision and good surface quality. Cold drawing is a production process that makes HPB300 grade steel bars with a diameter of 6 to 8 mm pass through a special tungsten alloy wire drawing die hole with a gradually decreasing diameter at room temperature to make the steel bars produce plastic deformation to change their physical and mechanical properties.

[0003] However, during the primary cold drawing of the steel wire, the stress on the steel wire is very large because the shape of the steel wire needs to be changed. If the drawing force during cold drawing does not coincide with the axis of the steel wire or the axis of the cold drawing die, the steel wire can be easily broken. After being broken, the steel wire can easily bounce up and injure people, posing a safety hazard.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a steel wire cold-drawn structure with anti-breaking properties is proposed. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a straightening assembly. The steel wire that is plastically deformed by the wire drawing die passes through the hole in the sleeve and is then reeled up by the traction wheel.

At the same time, the steel wire rope can be limited to prevent it from deviating. The sleeve is assembled on the left end of the bearing seat through an adjustable bracket. Through customized adjustment, it can be ensured that the light emitted by the photoelectric sensor can pass through the interior of the positioning block to ensure that the drawing force coincides with the axis of the steel wire during cold drawing.

[0016] 2. When the utility model is in use, the steel wire enters the device through the wire entry hole opened in the left side panel. A guide wheel is arranged on the outside of the hole to prevent the steel wire from deviating.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a wire cold drawing structure with anti-breaking function includes a workbench 1 and a straightening assembly 17. A bearing seat 13 is fixedly installed on the right end of the workbench 1. The straightening assembly 17 is fixedly installed on the left end of the bearing seat 13. The straightening assembly 17 includes a sleeve 1701, a positioning block 1702, a side groove 1703, a straightening wheel 1704, a rotating pin 1705, an adjustable bracket 1706 and a connecting pin 1707. A positioning block 1702 is fixed on the left side of the top of the sleeve 1701, and the hole in the positioning block 1702 is parallel to the central axis of the sleeve 1701. Four side grooves 1703 are distributed in a circumferential array on the sleeve 1701, and the straightening wheel 1704 is rotatably installed inside the side groove 1703. A rotating pin 1705 is fixed on the right side of the bottom of the sleeve 1701, and the bottom of the rotating pin 1705 is rotatably connected to an adjustable bracket 1706. The end of the adjustable bracket 1706 away from the rotating pin 1705 is rotatably connected to the connecting pin 1707, and the connecting pin 1707 is fixed to the left end of the bearing seat 13. The steel wire that is plastically deformed by the wire drawing die 11 passes through the hole in the sleeve 1701 and is then reeled up by the traction wheel 14. During this process, the steel wire is straightened around by rotating the straightening wheels 1704 installed in the four side grooves 1703 arranged in the side wall array of the sleeve 1701, so as to improve the tightness and uniformity of the steel wire rope when it is reeled up. At the same time, the steel wire rope can be limited to prevent it from being offset. The sleeve 1701 is assembled to the left end of the bearing seat 13 through the adjustable bracket 1706. Through custom adjustment, it can be ensured that the light emitted by the photoelectric sensor 16 can pass through the interior of the positioning block 1702 to ensure that the drawing force coincides with the axis of the steel wire during cold drawing.

[0023] like Figure 1 to Figure 2 As shown, the two ends of the workbench 1 are integrally fixed with side panels 2, and the ends of the side panels 2 are rotatably installed with a bin cover 3 through a hinge, a wire entry hole 4 is penetrated through the left side panel 2, and a guide wheel 5 is arranged on the outside of the wire entry hole 4, and a reflective sheet 6 is arranged on the inside of the wire entry hole 4, an adjustment slot 7 is opened at the left end of the workbench 1, and a slider 8 is slidably arranged inside the adjustment slot 7, a screw rod 9 is fixedly connected to the top of the slider 8, and a locking nut 10 is threadedly matched at the root of the screw rod 9, a wire drawing die 11 is fixed to the top of the screw rod 9, and the wire drawing die A positioning block 12 is fixed on the left side of the top of the drawing die 11, and the hole in the positioning block 12 is parallel to the central axis of the wire drawing die 11. The steel wire enters the device through the wire entry hole 4 opened on the left side plate 2. A guide wheel 5 is arranged on the outside of the hole to prevent the steel wire from deviating. After the steel wire passes through the hole in the drawing die 11, the large-diameter metal round wire is drawn into a small-diameter metal round wire. In this process, the drawing die 11 slides in the adjustment groove 7 opened on the left side of the workbench 1 through the slider 8 at the end of the screw 9, and the screw 9 is used to adjust the wire drawing die 11. The locking nut 10 at the root fixes the position of the wire drawing die 11. Through custom adjustment, it can be ensured that the light emitted by the photoelectric sensor 16 can pass through the interior of the positioning block 2 12 to ensure that the drawing force coincides with the axis of the cold drawing die during cold drawing. A traction wheel 14 is rotatably installed in the middle of the bearing seat 13, and the traction wheel 14 is fixedly connected to the output end of the motor 15. A photoelectric sensor 16 is fixed to the right end of the bearing seat 13, and the light emitted by the photoelectric sensor 16 returns to the original path after reaching the reflective sheet 6 via the positioning block 1 1702 and the positioning block 2 12. When the light emitted by the photoelectric sensor 16 returns to the original path after reaching the reflective sheet 6 via the positioning block 1 1702 and the positioning block 2 12, it proves that the drawing force coincides with the axis of the steel wire and the axis of the cold drawing die during cold drawing. Otherwise, the start and stop of the motor 15 is controlled to prevent the steel wire from being broken during the wire drawing process. In addition, the internal space of the workbench 1 can be covered by a bin cover 3 rotatably installed at the ends of the side panels 2 on both sides, providing safety protection for the steel wire from being accidentally broken.

[0024] Working principle: When using this kind of steel wire cold drawing structure with anti-breaking, the steel wire enters the device through the wire entry hole 4 opened on the left side panel 2, and a guide wheel 5 is arranged on the outside of the hole to prevent the steel wire from deviating. After the steel wire passes through the hole in the wire drawing die 11, the large-diameter metal round wire is drawn into a small-diameter metal round wire. In this process, the wire drawing die 11 slides in the adjustment groove 7 opened on the left side of the workbench 1 through the slider 8 at the end of the screw 9, and the position of the wire drawing die 11 is fixed by the locking nut 10 at the root of the screw 9. Through custom adjustment, it can be ensured that the light emitted by the photoelectric sensor 16 can pass through the interior of the positioning block 2 12 to ensure that the drawing force coincides with the axis of the cold drawing die during cold drawing. When the light emitted by the photoelectric sensor 16 returns to the original path after reaching the reflective sheet 6 via the positioning block 1 1702 and the positioning block 2 12, it proves that the drawing force coincides with the axis of the steel wire and the axis of the cold drawing die during cold drawing. The start and stop of the motor 15 is controlled to prevent the steel wire from being broken during the wire drawing process. In addition, the internal space of the workbench 1 can be covered by a bin cover 3 installed by hinges at the ends of the side panels 2 on both sides, providing safety protection against accidental breaking of the steel wire. The steel wire that has been plastically deformed by the wire drawing die 11 passes through the hole in the sleeve 1701 and is then reeled in by the traction wheel 14. During this process, the steel wire is straightened on all sides by rotating the straightening wheels 1704 installed in the four side grooves 1703 arranged in the side wall array of the sleeve 1701, so as to improve the tightness and uniformity of the steel wire rope when it is reeled in. At the same time, the steel wire rope can be limited to prevent it from being offset. The sleeve 1701 is assembled to the left end of the bearing seat 13 through an adjustable bracket 1706. Custom adjustment can ensure that the light emitted by the photoelectric sensor 16 can pass through the interior of the positioning block 1702 to ensure that the drawing force coincides with the axis of the steel wire during cold drawing.
