DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1 to Figure 4As shown, the present embodiment aims to provide a wire drawing die alloy core processing equipment which can realize automatic core punching without complicated operations. In order to achieve the above purpose, the wire drawing die alloy core processing equipment provided in the present embodiment includes a frame 1 and a workbench 11 arranged on the top of the frame 1. In the present embodiment, the workbench 11 is arranged in a disc shape as a whole, and a boss is arranged at the rear end of the workbench 11 for installing and fixing the electric pulse puncher 14.

[0024] Taking into account that in order to achieve automated production, automatic loading and unloading are required. For this purpose, a loading hole and a blanking notch 111 are respectively provided on both sides of the workbench 11. Since the wire drawing die is generally cylindrical as a whole, in this embodiment, the loading hole is also a circular hole, and the diameter of the loading hole is slightly larger than the diameter of the wire drawing die to ensure the normal rise of the die core.

[0025] In order to enable the mold core to be lifted out from the loading hole, in the present embodiment, a loading mechanism 2 is provided on one side of the frame 1. Specifically, the loading mechanism 2 includes a rotating platform 21 and a placement table 22 provided on the rotating platform 21. In the present embodiment, the rotating platform 21 is a hollow rotating platform. Compared with the rotation control of a single motor, its rotation is more stable, and the placement table 22 is also arranged in a disc shape as a whole, and its diameter is larger than the diameter of the rotating platform 21. The purpose of such arrangement is mainly to facilitate the exposure of the through hole.

[0026] A core placement tube 23 is arranged on the top of the placement table 22. A through hole is arranged on the placement table 22. The through hole is connected to the model placement tube. It should be noted that the tube mouth of the core placement tube 23 should also be slightly larger than the diameter of the core. If there is no limiting component for the core, the diameter of the through hole should be smaller than the diameter of the core to avoid falling.

[0027] In order to push the mold core out of the loading hole, a lifting electric cylinder 3 is arranged on the frame 1. In the present embodiment, the main purpose of using the lifting electric cylinder 3 is to control the extension distance of the electric cylinder. The power end of the lifting electric cylinder 3 can be extended into the mold core placement tube 23. The lifting electric cylinder 3 is located below the loading hole. In this way, as the mold core placement tube 23 rotates to the bottom of the loading hole, the lifting electric cylinder 3 works, and its power end is extended into the through hole. According to the thickness of the mold core, the rising distance is controlled to ensure that only one mold core is exposed outside the loading hole.

[0028] In order to move the mold core to the bottom of the tool of the electric pulse puncher 14, a lever 12 is also provided on the workbench 11. Specifically, a motor reducer is provided under the workbench 11, and its power end passes through the center of the workbench 11 and is connected to a mounting cap. The lever 12 is welded to the side wall of the mounting cap. In this embodiment, in order to ensure stability, four levers 12 are provided on the mounting cap, and the angle between adjacent levers 12 is 90°. In this way, the lever 12 can be rotatably set on the workbench 11, and then the lever 12 moves the mold core from the loading hole to the bottom of the electric pulse puncher 14 and the blanking notch 111 by rotation.

[0029] Since the mold core is a cylindrical structure, in order to prevent the mold core from shifting during the shifting process, in the present embodiment, a material shifting arc plate 121 is further provided at the end of the shifting rod 12. The material shifting arc plate 121 is open in a trumpet shape. The material shifting arc plate 121 as a whole can be said to be similar to a U-shaped setting. The difference between the two parallel sides of the U-shape is that it diverges outward. There are two purposes of such a setting. One is to ensure the selection of the mold core, and the other purpose is to facilitate the cooperation with the arc baffle 13 to achieve better fixation.

[0030] In order to fix the mold core, an arc baffle 13 is also provided on the workbench 11. The arc baffle 13 is lifted and lowered on the workbench 11. When it is lifted on the workbench 11, it forms a limit for the mold core. At this time, the arc baffle 13 cooperates with the material shifting arc plate 121 to fix the mold core under the electric pulse punching machine 14. When the arc baffle 13 falls, the shifting rod 12 continues to work, driving the punched mold core to fall from the blanking notch 111.

[0031] Through the above-mentioned setting, it is only necessary to set a travel switch or a laser sensor at each stop position to achieve positioning, so as to realize automated production. Compared with the complex operation of the robot which requires programming, this structure is simple, reliable and easy to operate.

[0032] In order to ensure accurate blanking, in this embodiment, the blanking notch 111 is arranged in a square notch shape. The length of the square notch should be at least twice the length of the mold core.

[0033] In order to facilitate the collection of the perforated mold cores and to facilitate entering the next procedure, in this embodiment, a guide plate 4 is provided at the bottom of the blanking notch 111, and a conveyor belt 5 is provided below the guide plate 4. The guide plate 4 is inclined, which is also conducive to buffering the falling of the mold core.

[0034] Due to the setting of the guide plate 4, the mold core is similar to sliding down. Therefore, in order to facilitate the subsequent palletizing, in this embodiment, a limit plate 41 is set on the guide plate 4. The limit plate 41 is set close to both sides of the guide plate 4. The spacing between the two limit plates 41 forms a channel for the mold core to slide down. At the same time, a push plate 6 and a lifting plate 7 matching with the limit plate 41 are set on the conveyor belt 5. The push plate 6 and the lifting plate 7 are spaced apart. The setting of the push plate 6 and the lifting plate 7 allows the mold core to walk between the push plate 6 and the lifting plate 7. In this way, the mold core will be neatly arranged in a row on the conveyor belt 5, so as to facilitate subsequent use.

[0035] In order to further facilitate palletizing, a push electric cylinder 61 is provided on the side of the push plate 6 away from the conveyor belt 5, and the lifting plate 7 is provided on the side of the conveyor belt 5 through a cylinder or an electric cylinder. A material tray 8 is provided on the side of the lifting plate 7 away from the conveyor belt, and a limit stopper 9 is provided on the conveyor belt 5. In this way, when the mold cores are arranged in a row, the lifting plate 7 falls, and the push plate 6 starts to work, pushing the mold cores into the material tray 8. In this way, by adjusting the distance of each push of the push electric cylinder 61, the entire material tray 8 is fully covered.

[0036] Considering that the placement of the mold core still requires manual placement, in order to concentrate the work as much as possible and reduce labor, in this embodiment, the mold core placement tubes 23 are evenly distributed in a ring shape on the placement table 22. Specifically, in this embodiment, a total of 8 mold core placement tubes 23 are placed, and one mold core placement tube 23 can place about 20 mold cores. In this way, 160 mold cores can be processed in one work, and the staff only needs to place them and then go to other work stations to work.

[0037] In order to facilitate the placement of the mold core, in this embodiment, a support plate 24 is provided in the mold core placement tube 23, and a guide ear 241 is provided on the outer edge of the support plate 24. The guide ear 241 extends out of the mold core placement tube 23, and a guide groove 231 for the guide ear 241 to move up and down is provided on the mold core placement tube 23. At least two guide ears 241 are provided on the outer edge of the support plate 24. In this embodiment, four guide ears 241 are provided to ensure the stability of the rise. At the same time, the provision of the guide groove 231 also facilitates the adjustment of the mold core after the mold core is placed.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
