Description

Technical Field

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

[0002] As a basic fastener, the processing technology of screws has evolved continuously with the industrialization process. Modern screw processing integrates material science, plastic forming and precision manufacturing technologies to meet the mechanical properties and reliability requirements under different working conditions. Traditional processing uses metal wire rods such as carbon steel and stainless steel as raw materials, and forms the screw head and rod through cold heading, turning or hot forging processes. Among them, the cold heading technology has become the mainstream of mass production due to its advantages of high efficiency and less cutting, but it is limited by the mold accuracy and material ductility.

[0003] As the core tool for metal plastic forming, the inside of the cold heading mold generally has a hole in the shape of a screw in the middle, the lower side is thinner, the upper side is hexagonal or circular, and the inner diameter is larger than the lower side. The specific shape is determined by the screw to be manufactured. Its internal cleanliness is directly related to the screw forming accuracy and the service life of the mold. During the cold heading process, due to the continuous high-pressure impact on the mold, metal debris, lubricant residues and oxide layers are easily attached to the complex inner cavity. Traditional cleaning technologies mostly rely on manual brushing, ultrasonic cleaning or chemical solvent immersion, and there are significant limitations: it is difficult for manual operation to reach the complex internal structure of the mold, and the accumulation of residues is likely to cause surface scratches or dimensional deviations of the formed parts; although some existing automated cleaning equipment replaces part of the manual labor, due to the limitation of the fixed nozzle and general fixture design, it cannot adaptively adjust the spraying angle and pressure of the cleaning medium according to the inner cavity morphology of the mold, resulting in insufficient or overloaded cleaning intensity in local areas. Coupled with the insufficient clamping stability of the mold, it is easy to shift during the cleaning process, further exacerbating the problem of uneven cleaning. The above problems lead to an extended mold maintenance cycle and a rising product defect rate. There is an urgent need to develop a cleaning technology that integrates high-precision positioning, dynamic pressure regulation and intelligent cleaning path planning to achieve efficient and non-destructive full-round cleaning of cold heading molds. Summary of the Invention

[0004] In view of the above technical problems, the present invention discloses a processing device for a stamping mold used in screw processing, including a fixed mounting plate, a driving component is installed on the fixed mounting plate, a lower-layer mounting rod is installed at the output end of the driving component, the driving component drives the lower-layer mounting rod to rotate and extend, two profiling rods are hinged to the lower side of the lower-layer mounting rod, spray nozzles are installed on the profiling rods, and a torsion spring is installed between the profiling rods and the lower-layer mounting rod. In the natural state, the profiling rods remain horizontal. Through the above technical solution, the driving component drives the lower-layer mounting rod into the mold. Since the profiling rods are horizontal, they can enter the mold from either the upper side or the lower side. The internal shape of the mold is different, and the profiling rods can adapt to different shapes, keeping the distance between the spray nozzles and the inner wall of the mold as consistent as possible, with better cleaning effect and no damage to the mold.

[0005] Further, a profiling ball is installed at the end of the profiling rod, and the profiling ball is in contact with the inner wall of the mold.

[0006] Further, the spray head includes a first cleaning spray head and a second cleaning spray head. The first cleaning spray head is located above the profiling rod, and the second cleaning spray head is located below the profiling rod.

[0007] Further, an angle is formed between the first cleaning spray head and the profiling rod, and between the second cleaning spray head and the profiling rod. Through the above technical solution, during the process of the lower installation rod moving upward from bottom to top, if only one spray head is set, there will always be dead corners. If one spray head is set above the profiling rod, when the profiling ball has not completely entered the mold from bottom to top, the first cleaning spray head has already entered the mold, so the lowest end of the mold is not easy to clean. If the spray head is set below the profiling rod, when the profiling rod moves upward and leaves the mold, the spray head has not left yet, but the angular position changes due to the departure of the profiling rod. Therefore, setting the first cleaning spray head and the second cleaning spray head can achieve cleaning without dead corners.

[0008] Further, the driving assembly includes a lifting structure. A cleaning motor is fixedly installed at the output end of the lifting structure. A cleaning rod is fixedly installed on the rotating shaft of the cleaning motor, and the cleaning rod is fixedly connected to the lower installation rod.

[0009] Further, the lifting structure includes a first-level cylinder. A first-level moving plate is fixedly installed on the telescopic arm of the first-level cylinder. A second-level cylinder is fixedly installed below the first-level moving plate. A second-level moving plate is fixedly installed on the telescopic arm of the second-level cylinder, and the cleaning motor is fixedly installed on the second-level moving plate.

[0010] Further, two cleaning slide rods are fixedly installed on the fixed mounting plate. The distance between the two cleaning slide rods is greater than the diameter of the lower end of the mold and less than the diameter of the upper end of the mold.

[0011] Further, a support rod is fixedly installed on the fixed mounting plate. A feeding motor is fixedly installed on the support rod. Two feeding chutes are fixedly installed on the rotating shaft of the feeding motor. Feeding slide rods are slidably installed on the feeding chutes. The distance between the two feeding slide rods is greater than the diameter of the lower end of the mold and less than the diameter of the upper end of the mold.

[0012] Further, a limiting rod is fixedly installed on the upper side of one end of the feeding slide rod close to the driving assembly, and a lower side support rod is fixedly installed on the lower side. A roller is installed below the lower side support rod, and the roller is in contact with the fixed mounting plate to assist in walking. Through the above technical solution, the mold can naturally slide between the two feeding slide rods and fall between the two cleaning slide rods. And multiple molds can be sequentially placed on the cleaning slide rods. After the cleaning is completed, reverse rotation can lift all the molds, and then they can slide out from the other end of the cleaning slide rods.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: (1) Through the technical solution of the present invention, when the driving component drives the lower mounting rod into the mold, the profiling rods adopt a horizontally symmetric layout and an elastic hinge structure, and the profiling balls at their ends are in flexible contact with the inner wall of the mold through preloading springs. When there are asymmetric steps, chamfers or special-shaped curved surfaces in the inner cavity of the mold, the profiling rods can deflect radially adaptively, so that the cleaning nozzles I and II fixed to the lower mounting rod always maintain a constant distance from the inner wall of the mold. This not only avoids scratching of the mold caused by traditional rigid contact, but also forms a laminar flow coverage through equidistant spraying of the high-pressure cleaning medium (water-gas mixed flow), improving the cleaning efficiency, especially having a better cleaning effect on the slender holes with a large depth-diameter ratio.

[0014] (2) Through the technical solution of the present invention, during the upward movement of the lower mounting rod, the cleaning nozzle I is integrated on the upper side of the profiling rod and sprays obliquely downward, and the cleaning nozzle II is fixed on the lower side of the profiling rod and sprays obliquely. When the profiling ball has not fully entered the mold, in the first 10% stage of the stroke, the cleaning nozzle I preferentially performs circumferential cleaning on the chamfer area at the mold inlet; when the profiling rod is fully extended, the two nozzles work synchronously to cover the entire circumferential area of the inner wall of the mold. Experiments show that this design reduces the proportion of the blind area 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 adapt to the cleaning requirements of residues with different viscosities, reducing the comprehensive energy consumption.

[0015] (3) Through the technical solution of the present invention, the mold is centered and positioned through the V-shaped guide groove and two groups of feeding slide rods, and slides along the inclination angle to the profiling card slot of the cleaning slide rod by its own weight. Multiple molds are arranged at equal intervals through the indexing plate. During cleaning, the cleaning slide rod moves step by step, and cooperates with the lifting and rotation of the lower mounting rod to complete continuous operation. After cleaning, the cleaning slide rod rotates reversely to lift the mold, so that it slides out along the coating surface with the acceleration of gravity, which improves the handling efficiency by several times compared with the traditional manipulator and avoids surface indentations caused by fixture clamping.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1-7 shown, a processing device for a stamping die used in screw processing includes a fixed mounting plate 1. A driving assembly is installed on the cleaning slide bar 11. Four fixed support legs 2 are fixedly installed on the lower side of the fixed mounting plate 1. The fixed mounting plate 1 is cut from a steel plate. The fixed support legs 2 are steel pipes and are welded to the lower end of the fixed mounting plate 1 to support the fixed mounting plate 1 at a certain height.

[0026] In this embodiment, the driving assembly includes a lifting structure and a rotating structure. The output end of the lifting structure is fixedly connected to the rotating structure. The rotating structure includes a cleaning motor 16. The output end of the lifting structure is fixedly installed with the 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-layer mounting rod 20.

[0027] In this embodiment, the lifting structure includes a first-stage cylinder 12. A total of four first-stage cylinders 12 are provided and are all fixedly installed on the fixed mounting plate 1. A first-stage moving plate 13 is fixedly installed on the telescopic arm of the first-stage cylinder 12. The first-stage moving plate 13 is a square plate. The telescopic arm of the first-stage cylinder 12 is fixedly connected to the four corners of the first-stage moving plate 13 to drive the first-stage moving plate 13 to move downward. A second-stage cylinder 14 is fixedly installed on the lower side of the first-stage moving plate 13. A second-stage moving plate 15 is fixedly installed on the telescopic arm of the second-stage cylinder 14. Side wing plates 27 are fixedly installed on both sides of the second-stage moving plate 15. The telescopic arm of the second-stage cylinder 14 is fixedly connected to the side wing plates 27. The cleaning motor 16 is fixedly installed on the second-stage moving plate 15. The second-stage moving plate 15 is the output end of the lifting structure. Designing two-stage lifting can ensure that the telescopic stroke is sufficient and the occupied space is small when retracted. A total of four cleaning motors 16 are provided on the second-stage moving plate 15.

[0028] In this embodiment, two cleaning slide rods 11 are fixedly installed on the fixed mounting plate 1. The two cleaning slide rods 11 are arranged in parallel. The cleaning slide rods 11 are U-shaped. The distance between the two cleaning slide rods 11 is greater than the diameter of the lower end of the mold and less than the diameter of the upper end of the mold. The mold is placed on the two cleaning slide rods 11. The mold is divided into two parts. The upper part is a thick rod 29 and the lower part is a thin rod 28. That is, the distance between the two cleaning slide rods 11 is greater than the diameter of the thin rod 28 and less than the diameter of the thick rod 29. The thick rod 29 is stuck on the upper side of the two cleaning slide rods 11, and the thin rod 28 naturally hangs between the two cleaning slide rods 11. Clamping cylinders 18 are fixedly installed on both sides of the fixed mounting plate 1. Clamping plates 19 are fixedly installed on the telescopic arms of the clamping cylinders 18. The two clamping plates 19 clamp all the 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 convenient positioning and cleaning.

[0029] In this embodiment, support rods 4 are fixedly installed on the fixed mounting plate 1. There are two support rods 4, which are arranged in parallel. A feeding motor 5 is fixedly installed on each support rod 4. A feeding slideway 6 is fixedly installed on the rotating shaft of the feeding motor 5. There are two feeding slideways 6 in total. Feeding slide rods 7 are slidably installed on the feeding slideways 6. The two feeding slide rods 7 are arranged in parallel. The distance between the two feeding slide rods 7 is greater than the diameter of the lower end of the mold and less than the diameter of the upper end of the mold. The distance between the two feeding slide rods 7 is slightly greater than the distance between the outer sides of the two cleaning slide rods 11. The feeding motor 5 drives the feeding slideway 6 to rotate, and the feeding slideway 6 drives the feeding slide rod 7 to tilt, so that the mold can slide on the feeding slide rod 7.

[0030] In this embodiment, a limiting rod 8 is fixedly installed on the upper side of one end of the loading slide rod 7 close to the driving component, and a lower support rod 9 is fixedly installed on the lower side. A roller 10 is installed under the lower support rod 9. When the roller 10 is in contact with the fixed mounting plate 1, it assists in walking. Four molds are placed on the loading slide rod 7, and then the roller 10 is made to contact the fixed mounting plate 1 at the farthest end. Subsequently, the roller 10 slides on the fixed mounting plate 1 and gradually approaches the support rod 4, and the molds on the loading slide rod 7 will fall onto the cleaning slide rod 11. After cleaning is completed, the molds on the cleaning slide rod 11 can be lifted in the reverse direction, and then slide into the material box 3 from the loading slide rod 7. The material box 3 is installed on one side of the fixed mounting plate 1. The molds placed between the two loading slide rods 7 can slide down naturally and fall between the two cleaning slide rods 11. A plurality of cleaning slide rods 11 are provided, and multiple molds can be placed on the cleaning slide rods 11 in sequence. After cleaning is completed, rotating in the reverse direction can lift all the molds, and then they can slide out from the other end of the cleaning slide rod 11.

[0031] In this embodiment, a lower layer mounting rod 20 is installed at the output end of the driving component. The output end of the driving component is the cleaning rod 17. The two lower layer mounting rods 20 are fixedly installed on the lower side of the cleaning rod 17. The cleaning rod 17 drives the lower layer mounting rod 20 to rotate and extend. There is a gap between the two lower layer mounting rods 20. The gap is smaller than the diameter of the cleaning rod 17 and smaller than the space inside the mold. The thin rod 28 has a thin channel 30 inside, and the thick rod 29 has a hexagonal channel 31 inside. The inside of the thick rod 29 can be of different shapes, but the inner diameter is larger than that of the thin channel 30. Two profiling rods 23 are hinged to the lower side of the lower layer mounting rod 20. Sprayers are installed on the profiling rods 23. A torsion spring 26 is installed between the profiling rod 23 and the lower layer mounting rod 20. Specifically, a rotating shaft 25 is rotatably installed on the lower layer 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 layer mounting rod 20 and the rotating shaft 25. In the natural state, the profiling rod 23 maintains a horizontal state. The driving component drives the lower layer mounting rod 20 to enter the inside of the mold. Since the profiling rod 23 is horizontal, it can enter the mold from either the upper side or 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 sprayer and the inner wall of the mold is kept as consistent as possible, the cleaning effect is better, and the mold will not be damaged at the same time.

[0032] The end of the profiling rod 23 is equipped with a profiling ball 24, and the profiling ball 24 is in contact with the inner wall of the mold. The profiling ball 24 can roll in any direction, so whether it slides up and down or rotates in the mold, it can be successfully completed. The nozzle includes a cleaning nozzle one 21 and a cleaning nozzle two 22. The cleaning nozzle one 21 is located above the profiling rod 23, and the cleaning nozzle two 22 is located below the profiling rod 23. An angle is formed between the cleaning nozzle one 21 and the profiling rod 23, and between the cleaning nozzle two 22 and the profiling rod 23. In other embodiments, the cleaning nozzle one 21, the cleaning nozzle two 22 and the profiling rod 23 are arranged in parallel, but there is a certain distance. As long as it can ensure that the positions where the cleaning nozzle one 21 and the cleaning nozzle two 22 spray water are different from the positions where the profiling ball 24 contacts the side wall. Through the above technical solution, during the process of the lower mounting rod 20 moving upward from the bottom, if only one nozzle is set, there will always be dead corners. If one nozzle is set above the profiling rod 23, then when the profiling ball 24 has not completely entered the mold from the bottom up, the cleaning nozzle one 21 has already entered the mold, so the lowest end of the mold is not easy to clean. If the nozzle is set below the profiling rod 23, then when the profiling rod 23 moves upward and leaves the mold, the nozzle has not left yet, but the angular position changes due to the departure of the profiling rod 23. Therefore, setting the two cleaning nozzles one 21 and two 22 can clean without dead corners.

[0033] Working principle: Make the roller 10 contact the fixed mounting plate 1, and the roller 10 is at the position farthest from the support rod 4. Then place the four molds on the loading slide bar 7. At this time, the loading slide bar 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. Subsequently, start the loading motor 5. The loading motor 5 drives the loading slideway 6 to rotate, so that the end of the loading slideway 6 close to the drive assembly descends. The loading slide bar 7 follows the rotation, and the roller 10 slides on the fixed mounting plate 1 and slides toward the position close to the support rod 4. At this time, the mold is stuck on the cleaning slide bar 11 and disengages from the upper side of the loading slide bar 7. Finally, all the molds fall on the cleaning slide bar 11.

[0034] Then start the clamping cylinder 18. The clamping cylinder 18 drives the clamping plate 19. The clamping plate 19 clamps the mold from both sides and plays a positioning role. Start the first-stage cylinder 12 to descend. The first-stage cylinder 12 drives the entire first-stage moving plate 13 to descend. Then start the second-stage cylinder 14. The second-stage cylinder 14 drives the second-stage moving plate 15 to descend, so that the cleaning rod 17 is inserted into the mold. During the process, since the profiling rod 23 is horizontal, the lower mounting rod 20 first enters the mold. The ends of the two profiling rods 23 gradually move upward and finally pass through the mold. When the profiling rod 23 completely disengages from the lower side of the mold, start in the reverse direction. At this time, the cleaning rod 17 and the lower mounting rod 20 move upward. The profiling balls 24 on the profiling rod 23 enter from the lower side of the mold. First, the ends of the profiling rod 23 move downward, and then the profiling balls 24 fit the fine channel 30. At this time, the first cleaning nozzle 21 and the second cleaning nozzle 22 start to spray water. The lower mounting rod 20 gradually moves upward. When the lower second cleaning nozzle 22 also enters the fine channel 30, the lowermost 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.

[0035] When the profiling ball 24 disengages from the fine channel 30, it will tend to return to the horizontal under the action of the torsion spring 26. Then the profiling ball 24 contacts the side wall of the hexagonal channel 31. At this time, the second-stage cylinder 14 does not contact the bottom end of the hexagonal channel 31 because the profiling ball 24 starts to disengage from the upper end of the fine channel 30 and then rotates to a position slightly away from the bottom of the hexagonal channel 31. At this time, the lower second cleaning nozzle 22 can clean the bottom of the hexagonal channel 31. Since the hexagonal channel 31 is not circular and the distance between the side wall and the axis is not the same, the profiling ball 24 will also change in height when rotating. At this time, the profiling ball 24 is not at the lowest end, leaving room for height change. Subsequently, before the profiling ball 24 leaves the hexagonal channel 31, the upper first cleaning nozzle 21 finishes cleaning the upper end of the hexagonal channel 31. After that, the driving assembly rises to the highest position. The first-stage cylinder 12 releases the mold. Start the feeding motor 5. The cleaning slide rod 11 lifts the cleaned mold from the lower end and then approaches the bottom end of the material box 3 at a lower position. The mold gradually falls into the material box 3.
