Description

Technical Field

[0001] The utility model relates to the field of cold heading machines, in particular to a feeding device for cold heading machines. Background Art

[0002] The cold piercing machine is a stamping machine in mechanical manufacturing. During the production and processing of screws, a disc wheel frame is placed at the feed port of the cold piercing machine. The disc wheel frame rotates to carry a bending disc, and a steel wire is wound on the bending disc. The steel wire enters the cold piercing machine through the feed port and is pulled and moved by the traction mechanism. At this time, the bending disc rotates.

[0025] The front shape of the No. 1 limiting wheel 4 is an inverted cone, and the size of the No. 1 limiting wheel 4 is the same as that of the No. 2 limiting wheel 5. By setting the No. 1 limiting wheel 4, when limiting and clamping steel wires with different diameters, the steel wire is pressed against the side of the No. 1 limiting wheel 4, and the threaded column 7 is rotated at this time, so that the threaded column 7 can drive the lifting plate 6 to move up and down, so that the lifting plate 6 can drive the No. 2 limiting wheel 5 to press tightly against the outside of the steel wire, so that the No. 1 limiting wheel 4 and the No. 2 limiting wheel 5 can clamp the steel wire, thereby achieving the clamping and limiting effect of steel wires with different diameters, avoiding the problem that the guide wheel is fixed in size and difficult to clamp and guide steel wires with different diameters, thereby improving the practical effect of the feeding device.

[0026] The output shaft of the rotating motor 3 is movably sleeved on the top of the inner cavity of the limiting cover 2, and there are two rotating motors 3. By setting the rotating motor 3, when wire guiding and conveying is required, the rotating motor 3 is started, so that the rotating motor 3 can drive the No. 1 limiting wheel 4 to rotate, that is, drive the clamped wire to move, thereby achieving the guiding effect of the wire.

[0027] The limiting mechanism 8 includes a No. 1 permanent magnet 81, which is fixedly connected to the top of the No. 1 limiting wheel 4, and a No. 2 permanent magnet 82 is fixedly connected to the bottom of the No. 2 limiting wheel 5; by setting the limiting mechanism 8, when the position of the No. 2 limiting wheel 5 is adjusted, the No. 1 permanent magnet 81 can support the No. 2 permanent magnet 82 through repulsion, so that the No. 2 permanent magnet 82 can push the No. 2 limiting wheel 5 to move upward, thereby achieving the effect of separating the No. 1 limiting wheel 4 from the No. 2 limiting wheel 5.

[0028] The pressing mechanism 9 includes a pressing column 91, which is fixedly connected to the bottom of the lifting plate 6, and a No. 1 sliding ball 92 is movably sleeved on the bottom of the pressing column 91; by setting the pressing mechanism 9, when the steel wire moves to drive the No. 2 limiting wheel 5 to rotate, the pressing column 91 can press and limit the rotating No. 2 limiting wheel 5 through the No. 1 sliding ball 92, thereby avoiding the problem of up and down fluctuations of the No. 2 limiting wheel 5 during rotation, thereby improving the stability of the position of the No. 2 limiting wheel 5.

[0029] The sliding mechanism 10 includes a limiting groove 101, which is provided on the side of the limiting cover 2, and a second sliding ball 102 is movably sleeved on the front of the inner wall of the limiting groove 101; by setting the sliding mechanism 10, when the lifting plate 6 moves up and down, the limiting groove 101 and the second sliding ball 102 can limit the lifting plate 6 moving up and down, thereby avoiding the problem of friction between the lifting plate 6 and the inner wall of the limiting groove 101 when moving up and down, thereby improving the position stability of the lifting plate 6 when moving up and down.

[0030] There are several anti-skid grooves 11, and the several anti-skid grooves 11 are evenly distributed on the outside of the No. 1 limiting wheel 4; by setting the anti-skid grooves 11, when the steel wire is guided, the anti-skid grooves 11 can greatly improve the friction between the No. 1 limiting wheel 4 and the steel wire, thereby avoiding the problem of sliding during steel wire guiding due to the relatively smooth surface of the steel wire, thereby improving the stability of the steel wire guiding.

[0031] The moving mechanism 12 includes a support column 121, which is fixedly connected to the bottom of the support platform 1, and a sliding wheel 122 is installed at the bottom of the support column 121; by setting the moving mechanism 12, when the feeding device needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 122 can drive the support platform 1 to move horizontally through the support column 121, that is, drive the limit cover 2 to move horizontally, thereby achieving the horizontal movement effect of the feeding device, which brings convenience to the adjustment of the working position of the feeding device.

[0032] The working principle of a feeding device for a cold heading machine provided by the utility model is as follows:

[0033] The first step: First, when clamping steel wires with different diameters, press the steel wire against the side of the No. 1 limiting wheel 4. At this time, rotate the threaded column 7 so that the threaded column 7 can drive the lifting plate 6 to move up and down, so that the lifting plate 6 can drive the No. 2 limiting wheel 5 to press tightly against the outside of the steel wire, so that the No. 1 limiting wheel 4 and the No. 2 limiting wheel 5 can clamp the steel wire, thereby achieving the clamping and limiting effect of steel wires with different diameters, avoiding the problem that the guide wheel is fixed in size and is difficult to clamp and guide steel wires with different diameters, thereby improving the practical effect of the feeding device. When wire guiding and conveying is required, start the rotating motor 3 so that the rotating motor 3 can drive The No. 1 limiting wheel 4 rotates, which drives the clamped steel wire to move, thereby achieving the effect of guiding the steel wire. When the position of the No. 2 limiting wheel 5 is adjusted, the No. 1 permanent magnet 81 can support the No. 2 permanent magnet 82 through repulsion, so that the No. 2 permanent magnet 82 can push the No. 2 limiting wheel 5 to move upward, thereby achieving the effect of separating the No. 1 limiting wheel 4 from the No. 2 limiting wheel 5. When the steel wire moves and drives the No. 2 limiting wheel 5 to rotate, the pressing column 91 can press and limit the rotating No. 2 limiting wheel 5 through the No. 1 sliding ball 92, so as to avoid the problem of up and down fluctuation of the No. 2 limiting wheel 5 when rotating, thereby improving the stability of the position of the No. 2 limiting wheel 5.

[0034] Step 2: When the lifting plate 6 moves up and down, the limit groove 101 and the second sliding ball 102 can limit the lifting plate 6 that moves up and down, so as to avoid the problem of friction between the lifting plate 6 and the inner wall of the limit groove 101 when the lifting plate 6 moves up and down, thereby improving the position stability of the lifting plate 6 when it moves up and down. When the steel wire is guided, the anti-slip groove 11 can greatly increase the friction between the No. 1 limit wheel 4 and the steel wire, so as to avoid the problem of sliding during steel wire guiding due to the relatively smooth surface of the steel wire, thereby improving the stability of steel wire guiding. When the feeding device needs to be moved and transported, the support platform 1 is pushed so that the sliding wheel 122 can drive the support platform 1 to move horizontally through the support column 121, that is, drive the limit cover 2 to move horizontally, thereby achieving the horizontal movement effect of the feeding device, that is, it brings convenience to the adjustment of the working position of the feeding device.

[0035] Compared with the related art, the feeding device for cold heading machine provided by the utility model has the following beneficial effects:

[0036] By setting the No. 1 limiting wheel 4, when limiting and clamping steel wires with different diameters, the steel wire is pressed against the side of the No. 1 limiting wheel 4, and the threaded column 7 is rotated at this time, so that the threaded column 7 can drive the lifting plate 6 to move up and down, so that the lifting plate 6 can drive the No. 2 limiting wheel 5 to press tightly on the outside of the steel wire, so that the No. 1 limiting wheel 4 and the No. 2 limiting wheel 5 can clamp the steel wire, thereby achieving the clamping and limiting effect of steel wires with different diameters, avoiding the problem that the guide wheel is fixed in size and difficult to clamp and guide steel wires with different diameters, thereby improving the practical effect of the feeding device.
