Description

Technical Field

[0001] The present invention relates to the technical field of mold cleaning, and in particular to processing equipment for a stamping mold for screw processing. Background Art

[0002] Screw processing technology, as a fundamental fastener, has evolved with industrialization. Modern screw processing integrates materials science, plastic forming, and precision manufacturing techniques to meet the mechanical performance and reliability requirements of various operating conditions. Traditionally, screw heads and shanks are formed from metal wires such as carbon steel and stainless steel through cold heading, turning, or hot forging. Cold heading, with its high efficiency and minimal cutting effort, has become the mainstream method for mass production, but it is limited by mold precision and material ductility.

[0003] As the core tool for metal plastic forming, the cold heading die generally has a screw-shaped hole in the middle of the die. The lower side is relatively thin, and the upper side is hexagonal or round, with an inner diameter larger than the lower side. The specific shape is determined by the screw to be made, and its internal cleanliness is directly related to the screw forming accuracy and the service life of the die. During the cold heading process, the die is continuously subjected to high-pressure impact, and metal debris, lubricant residue and oxide layer are easily attached to the complex inner cavity. Traditional cleaning technologies mostly rely on manual brushing, ultrasonic cleaning or chemical solvent immersion, which have significant limitations: manual operation is difficult to reach the complex internal structure of the die, and the accumulation of residues can easily cause scratches on the surface of the molded part or dimensional deviations; although existing automated cleaning equipment can partially replace manpower, it is limited by the fixed nozzle and universal fixture design, and cannot adaptively adjust the spray angle and pressure of the cleaning medium according to the morphology of the mold cavity, resulting in insufficient cleaning intensity or overload in local areas. In addition, the mold clamping stability is insufficient, and it is easy to offset during the cleaning process, further exacerbating the problem of uneven cleaning. The above problems have led to extended mold maintenance cycles and increased product defect rates. There is an urgent need to develop a cleaning technology that integrates high-precision positioning, dynamic pressure control and intelligent cleaning path planning to achieve efficient and non-destructive all-round cleaning of cold heading molds. Summary of the Invention

[0004] In response to the above technical problems, the present invention discloses a processing device for a stamping die for screw processing, comprising a fixed mounting plate, a driving assembly mounted on the fixed mounting plate, a lower mounting rod mounted on the output end of the driving assembly, the driving assembly driving the lower mounting rod to rotate and extend, two profiling rods hinged to the lower side of the lower mounting rod, a nozzle mounted on the profiling rod, a torsion spring mounted between the profiling rod and the lower mounting rod, and the profiling rod maintaining a horizontal state in a natural state. Through the above technical solution, the driving assembly drives the lower mounting rod to enter the interior of the die. Since the profiling rod is horizontal, it can enter the die from both the top and bottom sides. The internal shapes of the die are different, and the profiling rod can adapt to different shapes, so that the distance between the nozzle and the inner wall of the die is kept as consistent as possible, achieving a better cleaning effect without damaging the die.

[0005] Furthermore, a profiling ball is installed at the end of the profiling rod, and the profiling ball fits the inner wall of the mold.

[0006] Furthermore, the nozzle includes a cleaning nozzle 1 and a cleaning nozzle 2, wherein the cleaning nozzle 1 is located on the upper side of the profiling rod, and the cleaning nozzle 2 is located on the lower side of the profiling rod.

[0007] Furthermore, the first cleaning nozzle and the second cleaning nozzle each form an angle with the profiling rod. With the above technical solution, when the lower mounting rod moves upward from bottom to top, if only one nozzle is provided, there will always be a blind spot. If one nozzle is provided on the upper side of the profiling rod, the first cleaning nozzle will have already entered the mold before the profiling ball has fully entered the mold from bottom to top, making it difficult to clean the lowermost end of the mold. If the nozzle is provided on the lower side of the profiling rod, the nozzle has not yet left the mold when the profiling rod leaves the mold upward, but the angle position will change due to the departure of the profiling rod. Therefore, providing both the first cleaning nozzle and the second cleaning nozzle allows cleaning without blind spots.

[0008] Furthermore, the driving assembly includes a lifting structure, a cleaning motor is fixedly mounted on the output end of the lifting structure, a cleaning rod is fixedly mounted on the rotating shaft of the cleaning motor, and the cleaning rod is fixedly connected to the lower mounting rod.

[0009] Furthermore, the lifting structure includes a first-level cylinder, a first-level movable plate is fixedly installed on the telescopic arm of the first-level cylinder, a second-level cylinder is fixedly installed on the lower side of the first-level movable plate, a second-level movable plate is fixedly installed on the telescopic arm of the second-level cylinder, and the cleaning motor is fixedly installed on the second-level movable plate.

[0010] Furthermore, two cleaning slide bars are fixedly mounted on the fixed mounting plate, and a distance between the two cleaning slide bars is greater than a diameter of a lower end of the mold and smaller than a diameter of an upper end of the mold.

[0011] Furthermore, a support rod is fixedly mounted on the fixed mounting plate, a feeding motor is fixedly mounted on the support rod, two feeding slides are fixedly mounted on the rotating shaft of the feeding motor, a feeding slide rod is slidingly mounted on the feeding slide, and a distance between the two feeding slide rods is greater than the diameter of the lower end of the mold and smaller than the diameter of the upper end of the mold.

[0012] Furthermore, the upper end of the loading slide, closest to the drive assembly, is fixedly equipped with a limit rod, while the lower end is fixedly equipped with a lower support rod. Rollers are mounted below the lower support rod to assist in movement when the rollers are in contact with the fixed mounting plate. With this technical solution, a mold placed between the two loading slides can naturally slide down and land between the two cleaning slides. Multiple molds can be placed on the cleaning slides in sequence. After cleaning, the reverse rotation can lift all the molds and then slide them out from the other end of the cleaning slide.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] (1) Through the technical solution of the present invention, when the driving assembly drives the lower mounting rod into the mold, the profiling rod adopts a horizontally symmetrical layout and an elastic hinge structure, and the profiling ball at its end flexibly contacts the inner wall of the mold through a preloaded spring. When there are asymmetric steps, chamfers or special-shaped curved surfaces in the mold cavity, the profiling rod can adaptively deflect in the radial direction, so that the cleaning nozzles 1 and 2 fixed to the lower mounting rod always maintain a constant distance from the inner wall of the mold. This not only avoids mold scratches caused by traditional rigid contact, but also forms laminar coverage of the high-pressure cleaning medium (water-gas mixed flow) through equidistant injection, thereby improving cleaning efficiency, especially for slender holes with a high depth-to-diameter ratio.

[0015] (2) Through the technical solution of the present invention, during the upward movement of the lower mounting rod, cleaning nozzle 1 is integrated into the upper side of the profiling rod and sprays downward at an angle, while cleaning nozzle 2 is fixed to the lower side of the profiling rod and sprays at an angle. When the profiling ball has not fully entered the mold, during the first 10% of the stroke, cleaning nozzle 1 prioritizes circumferential cleaning of the mold entrance chamfer area; when the profiling rod is fully extended, the two nozzles work synchronously to cover the entire circumferential area of ​​the mold inner wall. Experiments show that this design reduces the proportion of blind spot cleaning area from 12.7% of the traditional single nozzle to 0.3%, and dynamically adjusts the flow ratio of the two nozzles through the pressure feedback system to meet the cleaning needs of residues with different viscosities, thereby reducing overall energy consumption.

[0016] (3) Through the technical solution of the present invention, the mold is aligned with the two sets of loading slides through the V-shaped guide groove and slides along the inclined angle into the contoured slot of the cleaning slide by its own weight. Multiple molds are arranged at equal intervals through the indexing plate. During cleaning, the cleaning slide moves in steps, and the continuous operation is completed in conjunction with the lifting and rotation of the lower mounting rod. After cleaning, the cleaning slide rotates in the opposite direction to lift the mold, so that it slides out along the coating surface with the acceleration of gravity. Compared with traditional manipulators, the handling efficiency is improved several times and the surface indentation caused by clamping is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments 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.

The rotating structure includes a cleaning motor 16. The output end of the lifting structure is fixedly equipped with a cleaning motor 16. A cleaning rod 17 is fixedly installed on the rotating shaft of the cleaning motor 16. The cleaning rod 17 is fixedly connected to the lower mounting rod 20.

[0028] In this embodiment, the lifting structure includes a first-level cylinder 12, a total of four first-level cylinders 12 are provided, all of which are fixedly mounted on the fixed mounting plate 1, and a first-level movable plate 13 is fixedly mounted on the telescopic arm of the first-level cylinder 12, and the first-level movable plate 13 is a square plate. The telescopic arm of the first-level cylinder 12 is fixedly connected to the four corners of the first-level movable plate 13, driving the first-level movable plate 13 to move downward, and a second-level cylinder 14 is fixedly mounted on the lower side of the first-level movable plate 13, and a second-level movable plate 15 is fixedly mounted on the telescopic arm of the second-level cylinder 14. Side wing plates 27 are fixedly mounted on both sides of the second-level movable plate 15, and the telescopic arm of the second-level cylinder 14 is fixedly connected to the side wing plates 27. The cleaning motor 16 is fixedly mounted on the second-level movable plate 15, and the second-level movable plate 15 is the output end of the lifting structure. The design of two-stage lifting can ensure that the telescopic stroke is sufficient and takes up little space when retracted. A total of four cleaning motors 16 are provided on the second-level movable plate 15.

[0029] In this embodiment, two cleaning slides 11 are fixedly mounted on the fixed mounting plate 1. The two cleaning slides 11 are arranged in parallel. The cleaning slides 11 are U-shaped. The distance between the two cleaning slides 11 is greater than the diameter of the lower end of the mold and smaller than the diameter of the upper end of the mold. The mold is placed on the two cleaning slides 11. The mold is divided into two parts, the upper end is a thick rod 29, and the lower end is a thin rod 28, that is, the distance between the two cleaning slides 11 is greater than the diameter of the thin rod 28 and smaller than the diameter of the thick rod 29. The thick rod 29 is stuck on the upper side of the two cleaning slides 11, and the thin rod 28 naturally hangs between the two cleaning slides 11. Clamping cylinders 18 are fixedly mounted on both sides of the fixed mounting plate 1. Clamping plates 19 are fixedly mounted on the telescopic arms of the clamping cylinders 18. The two clamping plates 19 clamp all molds from both sides. Positioning grooves are provided on the clamping plates 19. The two clamping plates 19 clamp the mold in the positioning grooves for easy positioning and cleaning.

[0030] In this embodiment, a support rod 4 is fixedly mounted on the fixed mounting plate 1. There are two support rods 4, which are arranged in parallel. A feeding motor 5 is fixedly mounted on each support rod 4. A feeding slide 6 is fixedly mounted on the rotating shaft of the feeding motor 5. There are two feeding slides 6 in total. A feeding slide bar 7 is slidably mounted on the feeding slide bar 6. The two feeding slide bars 7 are arranged in parallel. The distance between the two feeding slide bars 7 is greater than the diameter of the lower end of the mold and smaller than the diameter of the upper end of the mold. The distance between the two feeding slide bars 7 is slightly greater than the distance between the outer sides of the two cleaning slide bars 11. The feeding motor 5 drives the feeding slide bar 6 to rotate, and the feeding slide bar 6 drives the feeding slide bar 7 to tilt, so that the mold can slide on the feeding slide bar 7.

[0031] In this embodiment, a limiting rod 8 is fixedly installed on the upper side of one end of the feeding slide 7 close to the driving assembly, and a lower support rod 9 is fixedly installed on the lower side. A roller 10 is installed under the lower support rod 9. The roller 10 assists in walking when it is in contact with the fixed mounting plate 1. Four molds are placed on the feeding slide 7 and then the roller 10 is allowed to contact the fixed mounting plate 1 at the farthest end. Then the roller 10 slides on the fixed mounting plate 1 and gradually approaches the support rod 4. The molds on the feeding slide 7 will fall on the cleaning slide 11. After cleaning, the molds on the cleaning slide 11 can be lifted in the reverse direction, and then slid from the feeding slide 7 into the material box 3. The material box 3 is installed on one side of the fixed mounting plate 1. The molds are placed between the two feeding slides 7 and can slide naturally and fall between the two cleaning slides 11. If multiple molds are provided, multiple molds can be placed on the cleaning slide 11 in sequence. After cleaning, all molds can be lifted by reverse rotation and then slide out from the other end of the cleaning slide 11.

[0032] In this embodiment, the output end of the drive assembly is equipped with a lower mounting rod 20, and the output end of the drive assembly is a cleaning rod 17. The two lower mounting rods 20 are fixedly mounted on the lower side of the cleaning rod 17. The cleaning rod 17 drives the lower mounting rod 20 to rotate and telescope. A gap is left between the two lower mounting rods 20. The gap is smaller than the diameter of the cleaning rod 17 and smaller than the space in the mold. The thin rod 28 has a thin channel 30, and the thick rod 29 has a hexagonal channel 31. The thick rod 29 can be of different shapes, but the inner diameter is larger than the thin channel 30. The lower side of the lower mounting rod 20 is hinged with two profiling rods 23, and the profiling rod 23 is equipped with a nozzle. The profiling rod 23 and the lower mounting rod 20 are connected. A torsion spring 26 is installed in the middle. Specifically, a rotating shaft 25 is rotatably installed on the lower mounting rod 20. The rotating shaft 25 is fixedly connected to the profiling rod 23. A torsion spring 26 is sleeved on the rotating shaft 25. The two ends of the torsion spring 26 are respectively fixedly connected to the lower mounting rod 20 and the rotating shaft 25. In the natural state, the profiling rod 23 remains horizontal; the driving assembly drives the lower mounting rod 20 to enter the mold. Since the profiling rod 23 is horizontal, it can enter the mold from both the upper side and the lower side. The internal shape of the mold is different, and the profiling rod 23 can adapt to different shapes, so that the distance between the nozzle and the inner wall of the mold is kept consistent as much as possible, the cleaning effect is better, and the mold will not be damaged.

[0033] The end of the profiling rod 23 is equipped with a profiling ball 24, which fits against the inner wall of the mold. The profiling ball 24 can roll in any direction, allowing for smooth sliding and rotation within the mold. The nozzles include a cleaning nozzle 1 21 and a cleaning nozzle 22. Cleaning nozzle 1 21 is located above the profiling rod 23, while cleaning nozzle 22 is located below it. Both cleaning nozzle 1 21 and profiling rod 23 form an angle, as do cleaning nozzle 22 and profiling rod 23. In other embodiments, the cleaning nozzle 1 21, the cleaning nozzle 2 22 and the profiling rod 23 are arranged in parallel, but with a certain distance therebetween, as long as it can be ensured that the positions where the cleaning nozzles 1 21 and the cleaning nozzle 2 2 spray water are different from the positions where the profiling ball 24 contacts the side wall, through the above technical scheme, in the process of the lower mounting rod 20 moving from bottom to top, if only one nozzle is set, there will always be a dead angle. If one nozzle is set on the upper side of the profiling rod 23, then when the profiling ball 24 has not yet completely entered the mold from bottom to top, the cleaning nozzle 1 21 has already entered the mold, so the lower end of the mold is not easy to clean. If the nozzle is set on the lower side of the profiling rod 23, then when the profiling rod 23 leaves the mold upward, the nozzle has not left, but the angular position changes due to the departure of the profiling rod 23, so setting both the cleaning nozzle 1 21 and the cleaning nozzle 2 22 can perform cleaning without dead angles.

[0034] Working principle: let the roller 10 contact with the fixed mounting plate 1, and the roller 10 is at the position farthest from the support rod 4, and then place the four molds on the loading slide 7. At this time, the loading slide 7 is in an inclined state and automatically slides downward. The upper end of the mold contacts the limit rod 8 and will not fall. Then start the loading motor 5. The loading motor 5 drives the loading slide 6 to rotate, and the loading slide 6 is lowered close to the end of the drive assembly. The loading slide 7 rotates with it, and the roller 10 slides on the fixed mounting plate 1 and slides to a position close to the support rod 4. At this time, the mold is stuck on the cleaning slide 11 and detached from the upper side of the loading slide 7. Finally, the molds all fall on the cleaning slide 11.

[0035] Then start the clamping cylinder 18, which drives the clamping plate 19. The clamping plate 19 clamps the mold from both sides and plays a positioning role. Start the first-level cylinder 12 to descend. The first-level cylinder 12 drives the first-level movable plate 13 to descend as a whole. Then start the second-level cylinder 14, which drives the second-level movable plate 15 to descend, so that the cleaning rod 17 can be inserted into the mold. During the process, since the profiling rod 23 is in a horizontal position, the lower mounting rod 20 enters the mold first, and the ends of the two profiling rods 23 gradually move upward and finally pass through the mold. Wait until the profiling rod 23 is completely removed from the bottom. When the side is separated from the mold, it is started in the reverse direction. At this time, the cleaning rod 17 and the lower mounting rod 20 move upward, and the profiling ball 24 on the profiling rod 23 enters from the lower side of the mold. First, the end of the profiling rod 23 faces downward, and then the profiling ball 24 fits the fine channel 30. At this time, the cleaning nozzle 1 21 and the cleaning nozzle 2 22 start to spray water, and the lower mounting rod 20 gradually moves upward. When the cleaning nozzle 2 22 on the lower side also enters the fine channel 30, the lower side of the fine channel 30 is also cleaned. At the same time, the cleaning rod 17 and the lower mounting rod 20 rotate, and gradually clean upward while rotating.

[0036] When the profiling ball 24 leaves the fine channel 30, it will tend to return to the horizontal position under the action of the torsion spring 26, and then the profiling ball 24 contacts the side wall of the hexagonal channel 31. At this time, the secondary cylinder 14 will not contact the bottom end of the hexagonal channel 31, because the profiling ball 24 starts to separate from the upper end of the fine channel 30 and then rotates a little distance away from the bottom of the hexagonal channel 31. At this time, the lower cleaning nozzle 22 can clean the bottom of the hexagonal channel 31. Since the hexagonal channel 31 is not circular, the distance between the side wall and the axis is different, so During rotation, the contoured ball 24 will also change height. At this time, the contoured ball 24 is not at the bottom, leaving space for height changes. Then, before the contoured ball 24 leaves the hexagonal channel 31, the upper cleaning nozzle 21 completes the cleaning of the upper end of the hexagonal channel 31. After that, the driving assembly rises to the highest point, the first-stage cylinder 12 releases the mold, and the feeding motor 5 is started. The cleaning slide rod 11 lifts the cleaned mold from the lower end, and then is in a lower position close to the bottom end of the material box 3, and the mold gradually falls into the material box 3.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
