Abstract
Description
Technical Field
[0001] This invention relates to the field of fastener production and processing equipment technology, specifically to a bolt production and processing equipment. Background Technology
[0002] Bolt heads are typically formed using a stamping process. In the mass production of bolts, the raw material (usually steel) is placed in a stamping press using a die, and mechanical force is used to shape the material into the desired head shape. Stamping is characterized by low cost and high production efficiency, enabling rapid bolt head forming and meeting various design requirements.
[0003] However, existing technologies generally use cold stamping to form bolt heads. Cold stamping requires high precision in equipment, molds, and process control, resulting in higher production costs. In contrast, while hot stamping may have its applicability in certain specific situations, it is generally done manually because it is difficult to automatically unload freshly formed bolt heads. During hot stamping, the bolt falls from a height, leaving the bolt head at a high temperature, which can easily lead to collisions and compression, resulting in impact marks on the bolt head and even reducing its dimensions. Summary of the Invention
[0004] The purpose of this invention is to provide a bolt production and processing equipment that solves the problems of existing technology not being able to achieve automatic loading and unloading, as well as the appearance of collision marks on bolt heads and even the reduction in processing dimensions.

The middle position of the slide rail is located in cold water. The sliding plates are fixedly connected to the quenching box by a bracket.
[0013] In the preferred embodiment, the arc-shaped piece, arc-shaped block, positioning block, and clamping block are an integral structure.
[0014] In a preferred embodiment, a movable groove is fixedly provided on the base, and the lower stamping block is slidably disposed inside the movable groove.
[0015] In a preferred embodiment, the top dimensions of the lower stamping block are smaller than the diameter of the high-frequency heating coil.

[0037] like Figure 1 and 2As shown, a bolt manufacturing and processing equipment includes a base 1, a fixed bracket 2 fixedly mounted on the upper side of the base 1, a stamping mechanism 3 disposed inside the base 1, a high-frequency heating coil 5 fixedly connected to the side of the fixed bracket 2 via a fixed block 4, the high-frequency heating coil 5 being directly above the stamping mechanism 3, an automatic loading and unloading mechanism 7 rotatably connected to the side of the fixed bracket 2 via a fixed plate 6, the automatic loading and unloading mechanism 7 being above the high-frequency heating coil 5, a top stamping block 8 corresponding to the stamping mechanism 3 fixedly mounted on the top of the fixed bracket 2, a material box 9 fixedly mounted on the top of the fixed bracket 2 and on one side of the top stamping block 8, a slide rail 10 disposed on the fixed bracket 2, one end of the slide rail 10 being close to the automatic loading and unloading mechanism 7.

[0038] like Figure 1 and 3 As shown, the stamping mechanism 3 includes a hydraulic cylinder 301 fixedly mounted on the base 1. A lower stamping block 302 is fixedly connected to the upper output end of the hydraulic cylinder 301. A material groove 303 is provided on the upper part of the lower stamping block 302. A top block 304 is slidably mounted inside the material groove 303. A strong magnet 305 is fixedly mounted inside the top block 304. A top rod 306 is fixedly mounted on the lower part of the top block 304. A spring groove 307 is provided inside the lower stamping block 302 and below the material groove 303. The lower end of the top rod 306 extends into the spring groove 307 and is fixedly connected to a moving block 308. A compression spring 309 is provided on the lower part of the moving block 308 and inside the spring groove 307. The top length and width dimensions of the lower stamping block 302 are smaller than the diameter of the high-frequency heating coil 5, ensuring that the lower stamping block 302 can smoothly pass through the interior of the high-frequency heating coil 5 when moving up and down.
[0039] like Figure 4 and 5 As shown, the automatic loading and unloading mechanism 7 includes two parallel arc-shaped plates 701, with a groove 702 between them. An arc-shaped block 703 is fixedly mounted at the bottom of each arc-shaped plate 701, and positioning blocks 704 are fixedly mounted on both sides of the bottom of each arc-shaped plate 701. The sides of the positioning blocks 704 engage with the sides of the fixed plate 6. A clamping block 705 is positioned between the bottoms of the arc-shaped plates 701, and an inclined surface 706 is provided on the side of the clamping block 705 near the top of the arc-shaped plate 701. A spring-loaded spring (not shown) is provided at the rotatable part between the arc-shaped plate 701 and the fixed plate 6.

[0040] like Figure 6As shown, a stamping groove 801 is provided at the lower part of the top stamping block 8. The material box 9 includes a material box body 901, and a material outlet is provided at the bottom of the material box body 901. A movable plate 902 is slidably provided at the material outlet. The movable plate 902 is slidably connected to the side of the fixed bracket 2 through a slide rod 903.

A pressing plate 905 is provided at the lower part of the movable plate 902 to cooperate with the automatic loading and unloading mechanism 7.
[0041] like Figure 1 and 7 As shown, the slide 10 includes two parallel sliding plates 1001 with a gap 1002 between them. The slide 10 is inclined downward from both ends to the middle position. The middle position of the slide 10 is located in cold water. The sliding plates 1001 are fixedly connected to the quenching box 11 by a bracket.
[0042] like Figure 1-11 As shown, the specific working process of this embodiment is as follows:
[0043] The starting position of the operation in this embodiment is as follows: Figure 2 As shown, the unprocessed metal rod workpiece 12 is placed inside the material tank 303. Before the metal rod workpiece 12 is placed in the material tank 303, the top block 304 is still a certain distance away from the top of the material tank 303. After the metal rod workpiece 12 is placed inside the material tank 303, due to the weight of the metal rod workpiece 12 and the attraction of the strong magnet, the metal rod workpiece 12 will be firmly locked inside the material tank 303. Initially, the upper part of the metal rod workpiece 12 is located inside the high-frequency heating coil 5. After the high-frequency heating coil 5 is turned on, the upper part of the metal rod workpiece 12 can be heated.
[0044] like Figure 8 As shown, after the upper part of the metal rod workpiece 12 is heated, the high-frequency heating coil 5 automatically shuts off the power at the same time as the hydraulic cylinder of the stamping mechanism 3 is started. The stamping mechanism 3 drives the metal rod workpiece 12 to move upward. When the lower stamping block 302 is rising, the top edge (set as an arc) of the lower stamping block 302 begins to contact the bottom of the arc-shaped piece 701 and drives the arc-shaped piece 701 to start rotating. At this time, the metal rod workpiece 12 is located in the slide groove 702.
[0045] like Figure 9As shown, when the lower stamping block 302 continues to rise, it will come into complete contact with the top stamping block 8. The metal rod workpiece 12 is formed under the stamping action of the lower stamping block 302 and the top stamping block 8. At this time, the arc-shaped piece 701 is completely pushed to the side of the lower stamping block 302 by the lower stamping block 302. At the same time, the back of the arc-shaped piece 701 will press against the extrusion plate 905, causing the moving plate 902 to slide, thereby opening the opening of the material box 9 and dropping an unprocessed metal rod workpiece 12 from the material box 9. Since the unprocessed metal rod workpiece 12 will fall into the chute 702 and be located on the inclined surface 706, and since the bottom of the arc-shaped piece 701 is provided with an arc-shaped block 703, the outer contour of the arc-shaped block 703 has a side close to the lower stamping block 302. Therefore, the unprocessed metal rod workpiece 12 will not fall from the slide 702. When the unprocessed metal rod workpiece 12 falls into the slide, the inclined surface 706 itself has a certain inclination towards the lower stamping block 302, and the back of the arc-shaped piece 701 is blocked by the extrusion plate 905, so the unprocessed metal rod workpiece 12 will not fall from the back side of the slide 702. During the stamping process of the lower stamping block 302 and the top stamping block 8, in order to prevent the strong magnet 305 from bearing a large stamping force, the cross-sectional size of the strong magnet 305 can be equal to or smaller than the cross-sectional size of the top rod 306. In this way, during stamping, the stamping force at the bottom of the metal rod workpiece 12 is borne by the top block 304, which can better protect the strong magnet 305.
[0046] like Figure 10 As shown, after the stamping is completed, the lower stamping block 302 begins to descend. Due to the action of the compression spring 309, the formed metal rod workpiece 12 will still be fixed by the compression spring 309 before the lower stamping block 302 descends a certain distance, and the head of the formed metal rod workpiece 12 will still be located inside the stamping groove 801. As the lower stamping block 302 descends, the arc-shaped piece 701 will rotate counterclockwise due to the action of the spring (not shown), and the back side of the arc-shaped piece 701 will be located below the head of the formed metal rod workpiece 12. The unformed metal rod workpiece 12 will rotate together with the arc-shaped piece 701 in the slide groove 702.
[0047] like Figure 11 As shown, as the lower stamping block 302 continues to descend, since the size of the head of the formed metal rod workpiece 12 is larger than the width of the chute 702, the head of the metal rod workpiece 12 will be located on the upper back side of the arc plate 701. Finally, under the action of the arc plate 701, the bottom of the metal rod workpiece 12 will leave the material groove 303, while the unprocessed metal rod workpiece 12 will be located in the chute 702 and lie tilted on the inclined surface 706.
[0048] like Figure 12As shown, as the lower stamping block 302 continues to descend, the arc-shaped piece 701 will rotate to the starting position. At this time, the side of the positioning block 704 will abut against the side of the fixing plate 6, so that the arc-shaped piece 701 will no longer rotate. The final formed metal rod workpiece 12 will slide along the slide groove 702 onto the slide rail 10, and finally enter the quenching box 11 for quenching treatment. After the formed metal rod workpiece 12 falls, the bottom of the unprocessed metal rod workpiece 12 will fall above the material trough. Before the metal rod workpiece 12 is placed in the material trough 303, the top block 304 is still a certain distance away from the top of the material trough 303 and is attracted by the strong magnet 305. Due to the action of the strong magnet 305, and as the lower stamping block 302 further descends, the bottom edge of the reset inclined surface 706 will slowly straighten the unprocessed metal rod workpiece 12 and finally fall into the material trough 303. When the lower stamping block 302 returns to the starting position, the high-frequency heating coil 5 starts to start and the next processing is carried out.
[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
