Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of hexagonal bolt processing technology, and more specifically, to a cold heading machine for processing hexagonal bolts. Background Technology

[0002] A hex bolt is a fastener consisting of a head and a threaded shank. It typically comprises two parts: a head and a threaded cylindrical body (the shank). It requires a nut and is used to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection.

[0003] Cold heading machines are specialized equipment for the efficient, mass production of fasteners. Originating in Germany, they are widely used in the machinery manufacturing industry. Their working principle is based on the theory of metal plastic deformation, applying pressure to metal blanks at room temperature to plastically shape and size them. Cold heading machines offer advantages such as high production efficiency, high material utilization, and high product precision, and can adapt to various materials and production needs. In existing technologies, conventional cold heading machines first feed raw materials into the device through the inlet, then shape the bolts using the cold heading machine. However, in general, as raw materials accumulate at the inlet, blockages can occur, necessitating modification and optimization. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold heading machine for processing hexagonal bolts, comprising a base column and a cold heading machine, wherein the cold heading machine is fixedly disposed above the base column;

[0006] A feeding hopper is fixedly installed above the cold heading machine, a support mechanism is fixedly installed above the cold heading machine, a drive mechanism is fixedly installed above the support mechanism, a ring rack is movably installed on one side of the feeding hopper, two limiting rods are fixedly installed on one side of the feeding hopper, the two ends of the ring rack are movably sleeved with the limiting rods, and an L-shaped rod is fixedly installed on one side of the ring rack, one end of the L-shaped rod extending into the interior of the feeding hopper.

[0007] As a preferred embodiment of this utility model, a collection frame is fixedly installed on one side of the cold heading machine, a U-shaped frame is fixedly installed on one side of the collection frame, a motor is fixedly installed on one side of the U-shaped frame, a rotating plate is fixedly installed above the drive shaft of the motor, a rotating roller is fixedly installed at one end of the rotating plate, one end of the rotating roller extends into the interior of the collection frame and is fixedly installed with an eccentric block, a support plate is fixedly installed on one side inside the collection frame, a spring is fixedly installed above the support plate, and a sieve plate is fixedly installed above the spring.

[0008] As a preferred embodiment of this utility model, the support mechanism includes a vertical plate fixedly installed above the cold heading machine, a support plate fixedly installed above the vertical plate, and a motor fixedly installed above the support plate.

[0009] As a preferred technical solution of this utility model, the driving mechanism includes a second motor fixedly disposed above the support plate, and a second gear fixedly installed above the transmission shaft of the second motor, the second gear meshing with an annular rack.

[0010] As a preferred embodiment of this utility model, a guide plate is fixedly installed on one side of the cold heading machine, and the guide plate is located above the collection frame.

[0011] As a preferred embodiment of this utility model, a liquid outlet hole is provided on one side of the collection frame, and the liquid outlet hole extends into the interior of the collection frame.

[0012] As a preferred embodiment of this utility model, a bracket is fixedly installed above the collection frame, and a water pipe is fixedly installed above the bracket. One end of the water pipe passes through the upper and lower sides of the bracket and is fixedly installed with a nozzle.

[0013] As a preferred technical solution of this utility model, a controller is fixedly installed on one side of the cold heading machine, and the controller is electrically connected to motor one, nozzle and motor two.

[0014] As a preferred embodiment of this utility model, a baffle is fixedly installed above the sieve plate, and the baffle is located at one end above the sieve plate.

[0015] In a preferred embodiment of this utility model, the sieve plate is movably connected to the inner wall of the collection frame, and the sieve plate is located inside the collection frame, with a partition plate fixedly installed between the two inner sides of the collection frame.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, the second motor is started by the controller. After the second motor is started, the second gear rotates. Since the second gear meshes with the ring rack, it drives the ring rack to move up and down. The up and down movement of the ring rack drives the L-shaped rod to move up and down, pulling the raw material in the feed hopper up and down. Compared with the traditional device, this device avoids the phenomenon of blockage by pulling the raw material in the feed hopper up and down, thereby improving the efficiency of the device in processing hexagonal bolts.

[0018] 2. In this disclosure, the controller starts the motor one, which drives the rotating plate to rotate. The rotation of the rotating plate drives the rotating roller and the eccentric block to rotate, so that the eccentric block contacts the screen plate and drives the screen plate to move up. When the eccentric block is not in contact with the screen plate, the spring drives the screen plate to move down, realizing the up and down reciprocating motion of the spring. Compared with the traditional device, this device moves the screen plate up and down, so that the screen plate shakes the oil above the processed hexagonal bolts, so that the oil falls from the hexagonal bolts more quickly, improving the oil utilization rate.

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.

[0030] 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.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1 to 8 As shown, this utility model provides a cold heading machine for processing hexagonal bolts, including a base column 1 and a cold heading machine 2, which is fixedly installed above the base column 1;

[0036] A feed hopper 18 is fixedly installed above the cold heading machine 2. A support mechanism is fixedly installed above the cold heading machine 2. A drive mechanism is fixedly installed above the support mechanism. A ring rack 22 is movably installed on one side of the feed hopper 18. Two limit rods 23 are fixedly installed on one side of the feed hopper 18. The two ends of the ring rack 22 are movably connected to the limit rods 23. An L-shaped rod 24 is fixedly installed on one side of the ring rack 22. One end of the L-shaped rod 24 extends into the interior of the feed hopper 18.

[0037] When the operator uses the device, they first start the motor 20 via the controller 3. Once the motor 20 starts, it drives the gear 21 to rotate. When the gear 21 rotates, it meshes with the ring rack 22, causing the ring rack 22 to move up and down. When the ring rack 22 moves up and down, it drives the L-shaped rod 24 to move up and down. The up and down movement of the L-shaped rod 24 pulls the raw material inside the feed hopper 18 up and down.

[0038] The controller 3 starts the motor 20, which causes the gear 21 to rotate. Since the gear 21 meshes with the ring rack 22, it drives the ring rack 22 to move up and down. The up and down movement of the ring rack 22 drives the L-shaped rod 24 to move up and down, thus pulling the raw material in the feed hopper 18 up and down. Compared with the traditional device, this device avoids the phenomenon of blockage by pulling the raw material in the feed hopper 18 up and down, thereby improving the efficiency of the device in processing hexagonal bolts.

[0039] In some examples, a collection frame 4 is fixedly installed on one side of the cold heading machine 2, a U-shaped frame 7 is fixedly installed on one side of the collection frame 4, a motor 8 is fixedly installed on one side of the U-shaped frame 7, a rotating plate 9 is fixedly installed above the drive shaft of the motor 8, a rotating roller 10 is fixedly installed at one end of the rotating plate 9, one end of the rotating roller 10 extends into the interior of the collection frame 4 and an eccentric block 11 is fixedly installed thereon, a support plate 12 is fixedly installed on one side inside the collection frame 4, a spring 13 is fixedly installed above the support plate 12, and a sieve plate 14 is fixedly installed above the spring 13.

[0040] When the operator uses the device, they first start the motor 8 via the controller 3. When the motor 8 starts, it drives the rotating plate 9 to rotate. When the rotating plate 9 rotates, it drives the rotating roller 10 to rotate. When the rotating roller 10 rotates, it drives the eccentric block 11 to rotate. As the eccentric block 11 rotates, it comes into contact with the screen plate 14. When the eccentric block 11 rotates and comes into contact with the screen plate 14, it drives the screen plate 14 to move upward. When the eccentric block 11 is not in contact with the screen plate 14, the spring 13 drives the screen plate 14 to move downward, thus causing the screen plate 14 to move up and down back and forth.

[0041] The controller 3 starts the motor 8, which drives the rotating plate 9 to rotate. The rotation of the rotating plate 9 drives the rotating roller 10 and the eccentric block 11 to rotate, so that the eccentric block 11 contacts the screen plate 14 and drives the screen plate 14 to move upward. When the eccentric block 11 is not in contact with the screen plate 14, the spring 13 drives the screen plate 14 to move downward, realizing the up-and-down reciprocating motion of the spring 13. Compared with the traditional device, this device moves the screen plate 14 up and down, so that the screen plate 14 shakes the oil above the processed hexagonal bolts, so that the oil falls from the hexagonal bolts more quickly, improving the oil utilization rate.

[0042] In some examples, the support mechanism includes a vertical plate 19 fixedly mounted above the cold heading machine 2, a support plate 25 fixedly mounted above the vertical plate 19, and a motor 20 fixedly mounted above the support plate 25.

[0043] The design of the vertical plate 19 and the support plate 25 supports the position of the second motor 20, preventing instability during operation.

[0044] In some examples, the drive mechanism includes a second motor 20 fixedly mounted above the support plate 25, and a gear 21 fixedly mounted above the drive shaft of the second motor 20, the gear 21 meshing with the annular rack 22.

[0045] The controller 3 starts the motor 20, which drives the gear 21 to rotate. When the gear 21 rotates, it drives the ring rack 22 to move.

[0046] In some examples, a guide plate 5 is fixedly installed on one side of the cold heading machine 2, and the guide plate 5 is located above the collection box 4.

[0047] The guide plate 5 is designed to guide the processed hexagonal bolts and prevent them from falling to the outside of the device.

[0048] In some examples, a liquid outlet 6 is provided on one side of the collection frame 4, and the liquid outlet 6 extends into the interior of the collection frame 4.

[0049] The oil filtered out in the collection frame 4 is collected by the design of the liquid outlet 6 and then processed.

[0050] In some examples, a bracket 15 is fixedly installed above the collection box 4, and a water pipe 16 is fixedly installed above the bracket 15. One end of the water pipe 16 passes through the upper and lower sides of the bracket 15 and is fixedly installed with a nozzle 17.

[0051] The controller 3 activates the nozzle 17 to clean the hexagonal bolts above the screen plate 14, thereby improving the ease of operation and avoiding the need to rinse the hexagonal bolts.

[0052] In some examples, a controller 3 is fixedly installed on one side of the cold heading machine 2, and the controller 3 is electrically connected to the motor 8, the nozzle 17 and the motor 20.

[0053] The design of controller 3 controls the operation of the device, thereby improving the safety of device operation.

[0054] In some examples, a baffle 26 is fixedly installed above the sieve plate 14, and the baffle 26 is located at one end above the sieve plate 14.

[0055] The baffle 26 is designed to block the hexagonal bolts above the sieve plate 14, preventing them from falling directly from above the sieve plate 14 into the collection frame 4.

[0056] In some examples, the sieve plate 14 is movably connected to the inner wall of the collection frame 4, and the sieve plate 14 is located inside the collection frame 4, with a partition plate 27 fixedly installed between the two inner sides of the collection frame 4.

[0057] The design of the partition 27 isolates the hexagonal bolts and oil, preventing them from mixing again.

[0058] Working principle and usage process of this utility model:

[0059] When the operator uses the device, they first start the motor 20 via the controller 3. Once the motor 20 starts, it drives the gear 21 to rotate. When the gear 21 rotates, it meshes with the ring rack 22, causing the ring rack 22 to move up and down. When the ring rack 22 moves up and down, it drives the L-shaped rod 24 to move up and down. The up and down movement of the L-shaped rod 24 pulls the raw material inside the feed hopper 18 up and down.

[0060] When the operator uses the device, they first start the motor 8 via the controller 3. When the motor 8 starts, it drives the rotating plate 9 to rotate. When the rotating plate 9 rotates, it drives the rotating roller 10 to rotate. When the rotating roller 10 rotates, it drives the eccentric block 11 to rotate. As the eccentric block 11 rotates, it comes into contact with the screen plate 14. When the eccentric block 11 rotates and comes into contact with the screen plate 14, it drives the screen plate 14 to move upward. When the eccentric block 11 is not in contact with the screen plate 14, the spring 13 drives the screen plate 14 to move downward, thus causing the screen plate 14 to move up and down back and forth.

[0061] The cold heading machine 2 produces a workpiece of the desired shape by applying pressure to metal raw materials at room temperature, causing them to undergo plastic deformation.

[0062] 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.
