[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 5 In the existing thread rolling machine for metal fastener thread forming, the metal fasteners have different models and sizes, which makes it difficult to adjust the spacing between the slideways. In order to solve this technical problem, this embodiment discloses the following technical content;

[0026] A discharge hole 2 is opened in the middle of the front side of the bottom end of the storage box 1, and a storage box 3 is fixedly connected to the front side of the lower surface of the storage box 1, and the storage box 3 is fixedly connected to the rear side of the discharge hole 2. A first motor 4 is fixedly connected to the left side of the storage box 3, and a first bidirectional screw 5 is fixedly connected to the output shaft of the first motor 4, and the front sides of the left and right ends of the first bidirectional screw 5 are both threadedly connected to directional slideways 6;

[0027] The inner bottom surface of the storage box 1 has a low front and high rear structure, which facilitates the discharge of metal fasteners in the storage box 1 from the discharge hole 2. The spacing between the directional slides 6 is adjusted according to the size of the metal fasteners. The output shaft of the first motor 4 drives the first bidirectional screw 5 to rotate, so that the directional slides 6 at the two ends of the front side of the storage box 3 can move in opposite directions. The spacing between the directional slides 6 can be adjusted according to the size of the metal fasteners.

[0028] Embodiment 2: In the existing metal fastener thread forming processing thread rolling machine, it is time-consuming and laborious to manually arrange the metal fasteners in an orderly manner during processing, and it is not convenient to automatically agree on the direction of the metal fasteners. Therefore, this embodiment adopts the following technical solutions, such as Figure 1-Figure 5 As shown;

[0029] The left and right sides of the front bottom end of the directional slide 6 are fixedly connected to the conveying slide 7, and a connecting rod 8 is installed on the right side of the front end of the conveying slide 7, and the right side of the connecting rod 8 is fixedly connected to the bottom of the left front end of the mounting plate 15, and the left side of the connecting rod 8 is fixedly connected to the first automatic telescopic rod 9, and the output shaft of the first automatic telescopic rod 9 is fixedly connected to the push plate 10;

[0030] The bottom end of the directional slide 6 is in an inwardly contracted structure. When the metal fastener falls downward in the directional slide 6, the small end of the metal fastener falls from between the conveying slides 7, and the large end of the metal fastener cannot pass through the gap between the conveying slides 7. At this time, the large ends of the metal fasteners are uniformly placed above the conveying slide 7. After that, the metal fasteners are moved one by one to the front end of the conveying slide 7. The front metal fastener needs to be moved to the left for thread forming operation. At this time, the output end of the first automatic telescopic rod 9 moves to the left with the push plate 10, moving the metal fastener to the left side of the conveying slide.

[0031] Embodiment 3: The existing metal fastener thread forming machine is not convenient for stabilizing the metal fastener when processing the thread of the metal fastener. Therefore, this embodiment adopts the following technical solutions, such as Figure 1-6 As shown;

[0032] The left side of the front end of the lower surface of the storage box 1 is fixedly connected with a fixing device 11, and the fixing device 11 is composed of a mounting frame 1101, a second motor 1102, a second bidirectional screw 1103, a clamping plate 1104 and a storage slot 1105. The middle part of the lower surface of the mounting frame 1101 is fixedly connected with the second motor 1102, and the output shaft of the second motor 1102 is fixedly connected with the second bidirectional screw 1103, and both ends of the second bidirectional screw 1103 are threadedly connected with the clamping plate 1104, and the middle part of the top of the clamping plate 1104 is slidably connected. Connected to the storage slot 1105, the front end of the lower surface of the mounting frame 1101 is provided with a storage slot 1105, and the middle part of the bottom surface of the fixing device 11 is fixedly connected to the second automatic telescopic rod 12, and the output end of the second automatic telescopic rod 12 is fixedly connected to the third motor 13, the bottom end of the third motor 13 is rotatably connected to the upper surface of the middle part of the bottom end of the mounting frame 1101, and the output shaft of the third motor 13 is fixedly connected to the rolling device 14, and the right side of the storage box 1 is fixedly connected to the mounting plate 15, and the four corners of the mounting plate 15 are provided with mounting holes 16;

[0033] When the output end of the first automatic telescopic rod 9 carries the push plate 10 to push the metal fastener at the front end to the left, the second motor 1102 is started at this time, and the output shaft of the second motor 1102 drives the second bidirectional screw 1103 to rotate, so that the clamping plates 1104 at both ends of the second bidirectional screw 1103 move in the opposite direction to clamp the metal fastener. Then the second automatic telescopic rod 12 is started, and the output end of the second automatic telescopic rod 12 drives the third motor 13 to move up and down, and the output shaft of the third motor 13 drives the thread rolling device 14 to rotate, so that the thread rolling device 14 is driven by the second automatic telescopic rod 12 and the third motor 13 to move up and down and rotate, so that the thread rolling device 14 performs thread forming processing on the bottom end of the metal fastener. After the metal fastener is processed, the second motor 1102 is started, and the clamping plate 1104 releases the clamping of the metal fastener, and then pushes the next metal fastener to move forward, and the processed metal fastener is pushed out of the conveying slide 7. The above operation stabilizes the metal fastener undergoing thread forming processing to prevent the metal fastener from moving during processing.

[0034] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
