Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of mold technology, and more specifically, to a mold for processing stop washers. Background Technology
[0002] Locking washers are used to prevent nuts from loosening and are often paired with nuts. They come in two types: locking washers for round nuts, used for locking small round nuts in applications such as axial fixing of rolling bearings, where the inner and outer tongues of the washer mate with the shaft groove and the round nut groove respectively; and external tongue locking washers, suitable for general nuts, which achieve locking by bending the tongue to fit tightly against the connector and then folding it towards the side of the nut. Locking washers are generally formed by stamping using a die during manufacturing.
[0003] When stamping and forming stop washers, existing molds require placing the blank into the mold and then rapidly impacting and extruding it to form the stop washer. However, after prolonged use, the mold will cause some iron filings to adhere to the blank due to the impact. When stamping subsequent blanks, these iron filings will be squeezed onto the stop washers formed later, which can easily cause iron spikes to appear on the surface of the automatic washer, potentially injuring the hands of subsequent operators. Utility Model Content

[0047] like Figures 1-4As shown, this invention discloses a mold for processing stop washers according to one embodiment. The mold includes an upper mold 1 with a punch head 2, a through hole 3, a sliding column 4, a lifting mechanism, and a driving mechanism. A protective frame 18 is fixedly connected to the top of the upper mold 1, and a connecting shaft 19 is fixedly connected to the top of the protective frame 18 for easy connection to external driving equipment. The through hole 3 is formed on the upper mold 1 and matches the punch head 2. The sliding column 4 is slidably disposed within the through hole 3, and the punch head 2 is fixedly connected to the bottom end of the sliding column 4. The driving mechanism drives the lifting mechanism to move, thereby causing the sliding column 4 and the punch head 2 to rise within the through hole 3. When the plane of the bottom end of the punch head 2 is at the same height as the bottom plane of the mold 1, the iron filings adhering to the punch head 2 are removed through the edge of the through hole 3, thus achieving the effect of cleaning the punch head 2 and effectively preventing iron filings from being squeezed onto the subsequent stop washers, effectively preventing injury to operators.
[0048] A lifting mechanism is located at the top of the upper mold 1 and is used to drive the sliding column 4 and the stamping head 2 to move up and down. The lifting mechanism includes: wedge plates 5, wedge grooves 6, and support components. Two wedge plates 5 are arranged opposite each other, and there are two wedge plates 5. The two wedge plates 5 are set at the top of the upper mold 1 by a sliding component. Two wedge grooves 6 are opened, and the two wedge grooves 6 are opened opposite each other on the sliding column 4. The two wedge plates 5 are respectively set in the two wedge grooves 6. Each wedge groove 6 is provided with a support component to support the movement of the wedge plates 5 within the wedge groove 6. The sliding component includes: a support rod 7, a connecting rod 8, a sliding ring 9, and a sliding ring 9. The slide rod 10 is fixedly connected to two fixed plates 17 at the top of the upper mold 1. The slide rod 10 is fixedly connected to the two fixed plates 17. Support rods 7 are fixedly connected to the two wedge plates 5. Connecting rods 8 are fixedly connected to the two support rods 7. Sliding rings 9 are fixedly connected to the two connecting rods 8. The slide rod 10 is fixedly connected to the top of the upper mold 1. The sliding rings 9 are slidably connected to the slide rod 10. The support assembly includes a rotating shaft 11 and a support wheel 12. The rotating shaft 11 is fixedly connected to the two wedge grooves 6. The support wheel 12 is rotatably connected to the two rotating shafts 11. The two support wheels 12 are in contact with the two wedge plates 5 respectively.
[0049] When the support rod 7 moves, it drives the two wedge plates 5 to move relative to each other in the two wedge grooves 6. When the wedge plates 5 move, the support wheel 12 rolls on the surface of the wedge plates 5, thereby supporting the wedge plates 5 to move in the wedge grooves 6, thereby driving the sliding column 4 and the punch head 2 to rise, thereby removing the iron filings adhering to the punch head 2 through the edge of the through hole 3.
[0050] The drive mechanism is located at the top of the upper mold 1 and is used to drive the lifting mechanism to move. The drive mechanism includes: drive rod 13, drive block 14 and power component. Drive rod 13 is fixedly connected to both support rods 7. Drive block 14 is fixedly connected to the bottom end of both drive rods 13. The power component is located at the top of the upper mold 1 and is used to drive the two drive blocks 14 to move. The power component includes: bidirectional screw 15 and first motor 16. Bidirectional screw 15 is rotatably connected to the top of the upper mold 1. Both drive blocks 14 are provided with screw holes. Bidirectional screw 15 is threaded into the two screw holes. The two drive blocks 14 are respectively located at the two screws. The first motor 16 is installed at the top of the upper mold 1. The output end of the first motor 16 is fixedly connected to the bidirectional screw 15.
[0051] The first motor 16 drives the bidirectional screw 15 to rotate. When the bidirectional screw 15 rotates, it drives the two drive blocks 14 to move relative to each other, which in turn drives the two drive rods 13 to move relative to each other, thus facilitating the relative movement of the two support rods 7.
[0052] Working principle: When it is necessary to remove iron filings adhering to the stamping head 2, the first motor 16 drives the bidirectional screw 15 to rotate. When the bidirectional screw 15 rotates, it drives the two drive blocks 14 to move relative to each other, which in turn drives the two drive rods 13 to move relative to each other. This facilitates the relative movement of the two support rods 7. When the support rods 7 move, they drive the two wedge plates 5 to move relative to each other in the two wedge grooves 6. When the wedge plates 5 move, the support wheel 12 rolls on the surface of the wedge plates 5, thereby supporting the wedge plates 5 to move in the wedge grooves 6. This drives the sliding column 4 and the stamping head 2 to rise, thereby removing the iron filings adhering to the stamping head 2 through the edge of the through hole 3.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
