Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of hexagonal nut production equipment, and more specifically, to a cold heading machine for hexagonal nuts. Background Technology

[0002] A cold heading machine is a type of stamping machine used in mechanical manufacturing. It is mainly used to soften or harden raw materials to shape them into the required form.

[0003] Currently, operators frequently use cold heading machines when producing hexagonal nuts. While existing cold heading machines have the basic function of stamping raw materials into hexagonal nuts, after cold heading, the hexagonal nuts are discharged from the discharge port into the receiving frame. Due to the limited capacity of the receiving frame, when it is full, the operator needs to stop the cold heading machine, move the full receiving frame aside, place a new receiving frame at the bottom of the discharge port, and then restart the cold heading machine for processing and discharge. This process reduces the production efficiency of the cold heading machine, thus requiring improvement. Utility Model Content

A rotating shaft is fixedly sleeved at the other end of the output shaft of the servo motor. The other end of the rotating shaft passes through the protective cover and extends to the outside of the right side of the protective cover, and a long rod is fixedly sleeved on its outer surface. The outer surface of the rotating shaft is movably connected to the interior of the right end of the servo motor. A moving rod is hinged to the other end of the long rod. The other end of the moving rod is hinged to the front of the left side of the connecting block.

[0006] As a preferred embodiment of this utility model, a base is fixedly connected to the left side of the top of the rectangular plate, a cold heading machine body is fixedly installed on the top of the base, and a discharge port is fixedly installed on the right side of the cold heading machine body.

[0007] As a preferred embodiment of this utility model, the bottom end of the movable plate is fixedly connected to a guide block located inside the table leg, and the outer surface of the guide block is movably connected to the inside of the table leg.

[0008] As a preferred technical solution of this utility model, a rectangular block is fixedly connected to the right side of the top of the movable plate, and a pneumatic cylinder is fixedly installed on the right side of the rectangular block. The left end of the pneumatic cylinder passes through the rectangular block and extends to the outside of the left side of the rectangular block.

[0009] As a preferred embodiment of this utility model, a clamping plate is fixedly connected to the left end of the pneumatic cylinder, and the bottom end of the clamping plate is movably connected to the top end of the movable plate.

[0010] As a preferred embodiment of this utility model, springs inside the table legs are fixedly connected to the front and rear sides of the top right side of the rectangular plate, and the top of the springs is fixedly connected to the bottom of the workbench.

[0011] As a preferred embodiment of this utility model, a protective cover is fixedly connected to the right side of the top of the rectangular plate, and a drive motor is fixedly installed inside the protective cover.

[0012] As a preferred embodiment of this utility model, the other end of the output shaft of the drive motor is fixedly sleeved with a rotating shaft, and the left end of the rotating shaft passes through the protective cover and extends to the outside of the left side of the protective cover, with its outer surface being movably connected to the inside of the left end of the protective cover.

[0013] As a preferred embodiment of this utility model, a movable block is fixedly sleeved on the outer surface of the rotating shaft, and the movable block has a convex shape.

[0014] In a preferred embodiment of this invention, the table legs are four in number, and all four table legs are of the same size.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. In this disclosure, by setting up a servo motor, a rotating shaft, a long rod, and a moving rod, when any receiving frame at the top of the movable plate is filled with hexagonal nuts, the operator only needs to start the servo motor to drive the rotating shaft and simultaneously drive the long rod to rotate. At this time, the moving rod will generate a horizontal pulling force and pull the connecting block to move the movable plate forward. During this process, the receiving frame filled with hexagonal nuts moves away from directly below the discharge port, while the empty receiving frame moves to the bottom of the discharge port. This allows the cold heading machine to complete efficient and uninterrupted receiving operations while it is running, significantly improving production efficiency.

[0017] 2. In this disclosure, by setting up a spring, a drive motor, a rotating shaft, and a movable block, when the operator starts the drive motor, the rotating shaft will drive the eccentrically set movable block to rotate in a circular motion. As the movable block rotates, its outer surface will periodically press the bottom of the worktable, causing the worktable to move upward. At this time, the spring will be stretched. When the movable block rotates to the point of disengaging from the bottom contact surface of the worktable, the spring's elastic force will restore the worktable downward. This process repeats, which will generate vibration on the worktable. This will effectively prevent material accumulation during the process of the hexagonal nut falling from the discharge port into the receiving frame, achieve uniform material distribution, and significantly improve the uniformity of material distribution.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled.

[0032] like Figures 1-6As shown, a cold heading machine for hexagonal nuts disclosed herein is illustrated, comprising a rectangular plate 1, with table legs 2 fixedly connected to the front and rear of the right side of the top of the rectangular plate 1, a worktable 3 movably connected to the top of the table legs 2, a movable plate 4 movably connected to the interior of the top of the worktable 3, a connecting block 5 fixedly connected to the left side of the top of the movable plate 4, a protective cover 6 fixedly connected to the left side of the front of the worktable 3, a servo motor 7 fixedly installed inside the protective cover 6, a rotating shaft 8 fixedly sleeved at the other end of the output shaft of the servo motor 7, the other end of the rotating shaft 8 passing through the protective cover 6 and extending to the outside of the right side of the protective cover 6, with a long rod 9 fixedly sleeved on its outer surface, the outer surface of the rotating shaft 8 movably connected to the interior of the right end of the servo motor 7, and a moving rod 10 hinged to the other end of the long rod 9, the other end of the moving rod 10 hinged to the front of the left side of the connecting block 5.

[0033] Due to the design of the movable plate 4, two receiving frames for receiving materials can be placed on the top of the movable plate 4. Due to the cooperation between the long rod 9 and the moving rod 10, the connecting block 5 and the movable plate 4 can move in the future. The design of the protective cover 6 can then provide good protection for the servo motor 7 inside.

[0034] In some examples, a base 11 is fixedly connected to the left side of the top of the rectangular plate 1, a cold heading machine body 12 is fixedly installed on the top of the base 11, and a discharge port 13 is fixedly installed on the right side of the cold heading machine body 12.

[0035] After the material inside the cold heading machine body 12 is cold-headed into a hexagonal nut, it will slide out from the outer surface of the discharge port 13.

[0036] In some examples, the bottom of the movable plate 4 is fixedly connected to a guide block 14 located inside the table leg 2, and the outer surface of the guide block 14 is movably connected to the inside of the table leg 2.

[0037] Due to the design of the guide block 14, it can effectively limit the movement of the movable plate 4.

[0038] In some examples, a rectangular block 15 is fixedly connected to the right side of the top of the movable plate 4, and a pneumatic cylinder 16 is fixedly installed on the right side of the rectangular block 15. The left end of the pneumatic cylinder 16 passes through the rectangular block 15 and extends to the outside of the left side of the rectangular block 15.

[0039] Because of the connection between the top of the movable plate 4 and the bottom of the rectangular block 15, when the movable plate 4 moves, it will drive the rectangular block 15 and the pneumatic cylinder 16 to move together.

[0040] In some examples, the left end of the pneumatic cylinder 16 is fixedly connected to a clamping plate 17, and the bottom end of the clamping plate 17 is movably connected to the top end of the movable plate 4.

[0041] Due to the design of the clamping plate 17, it is possible to effectively fix the two receiving frames at the top of the movable plate 4 in the subsequent operation.

[0042] In some examples, springs 18 inside the table legs 2 are fixedly connected to the front and rear of the top right side of the rectangular plate 1, and the top of the springs 18 are fixedly connected to the bottom of the workbench 3.

[0043] The design of the four springs 18 enables the worktable 3 to achieve a good reset effect during subsequent movements.

[0044] In some examples, a protective cover 19 is fixedly connected to the right side of the top of the rectangular plate 1, and a drive motor 20 is fixedly installed inside the protective cover 19.

[0045] Due to the design of the protective cover 19, the drive motor 20 can be well protected.

[0046] In some examples, the other end of the output shaft of the drive motor 20 is fixedly sleeved with a rotating shaft 21, the left end of which passes through the protective cover 19 and extends to the outside of the left side of the protective cover 19, and the outer surface is movably connected to the inside of the left end of the protective cover 19.

[0047] Since both the outer surface of the rotating shaft 21 and the inside of the protective cover 19 are smooth, the right side of the outer surface of the rotating shaft 21 rotates more smoothly inside the protective cover 19.

[0048] In some examples, a movable block 22 is fixedly fitted onto the outer surface of the rotating shaft 21, and the movable block 22 has a convex shape.

[0049] Because the movable block 22 is convex, it can continuously squeeze and push the bottom of the worktable 3 during subsequent circular motion.

[0050] In some examples, there are four table legs 2, and all four table legs 2 are the same size.

[0051] The design of the four table legs 2 provides excellent support for the workbench 3.

[0052] Working principle and usage process of this utility model:

[0053] First, the operator places the two receiving frames on the top of the movable plate 4, then activates the pneumatic cylinder 16, causing the clamping plate 17 to move to the left, thus fixing the two receiving frames. Subsequently, when the cold heading machine body 12 cold-heads the raw material into hexagonal nuts, the hexagonal nuts will be discharged along the discharge port 13 into the interior of one of the receiving frames at the top of the movable plate 4. At this time, the operator activates the drive motor 20, which will cause the rotating shaft 21 and the movable block 22 to rotate, thereby causing the outer surface of the movable block 22 to continuously squeeze and push the bottom of the worktable 3, thus causing the worktable 3 to move upward. At this time, the four springs 18 are in a stretched state. When the outer surface of the movable block 22 leaves the outer surface of the bottom of the worktable 3, due to the restoring effect of the elasticity of the four springs 18, the entire worktable 3 will move downward. This cycle will produce a vibration effect on the entire worktable 3, so that the hexagonal nuts can be evenly distributed inside the receiving frames, preventing accumulation.

[0054] Finally, when one of the receiving frames is full, the operator stops the drive motor 20 and starts the servo motor 7, which will cause the rotating shaft 8 and the long rod 9 to rotate. This will cause the moving rod 10 to pull the connecting block 5 and the movable plate 4 forward as a whole, so that the receiving frame filled with hexagonal nuts leaves the bottom of the discharge port 13, while the receiving frame without hexagonal nuts will move to the bottom of the discharge port 13 for receiving. Then, the operator runs the pneumatic cylinder 16 again to release the fixing of the two receiving frames. The operator can then move the receiving frame filled with hexagonal nuts without stopping the cold heading machine body 12. The operator can then repeat the above operation to fix the receiving frame again and make the hexagonal nuts inside the receiving frame evenly distributed.

[0055] 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.
