Description

Technical Field

[0001] The invention relates to the technical field of phosphorus saponification treatment of metal fasteners, in particular to phosphorus saponification lubrication equipment for large-scale weather-resistant and high-strength fasteners. Background Art

[0002] Cold extrusion is an important component of precision plastic bulk forming technology. A cold metal blank is placed into a mold cavity and forced out of the cavity under strong pressure and a certain speed, resulting in an extruded workpiece with the desired shape, size, and mechanical properties.

[0003] Phosphorus saponification is a common pre-treatment technology for cold extrusion. In principle, it belongs to the category of chemical conversion coating treatment. It is mainly applied to the surface of steel and is also applicable to non-ferrous metals (such as aluminum and zinc). Saponification evenly deposits a primary saponification film on the surface of the part, preparing it for cold extrusion.

[0004] After each step of phosphating, cleaning, and saponifying metal fasteners, the metal fasteners need to be dried to harden the film formed during the phosphating and saponifying process. Conventional methods for drying metal fasteners during the phosphating and saponifying process include either air drying or using a fan to accelerate the drying of the protective film on the metal fasteners. Natural drying is slow, while using a fan to accelerate drying requires manual power on and off, which is cumbersome.

[0037] The power self-starting mechanism is arranged at the rear of the mounting plate 6. The power self-starting mechanism includes a movable sleeve 81. The upper and lower parts of the movable sleeve 81 are provided with limit blocks 82. A linkage rod 83 is fixedly installed on the top of the upper limit block 82. The linkage rod 83 is fixedly connected to the upper lever 84 and the lower lever 85. A junction box 9 and a bracket 10 are also provided on the mounting plate 6. A connecting shaft 11 is provided on the upper part between the brackets 10. A wiring switch 12 is movably sleeved on the connecting shaft 11.

[0038] The blowing mechanism is arranged at the front of the mounting plate 6, and the blowing mechanism includes a motor 13, a rotating shaft 14, and a fan blade 15. The blowing mechanism is located directly above the hanging basket 73. The phosphorus soap pool 1 includes a phosphating pool 101 on the right, a cleaning pool 102 in the middle, and a saponification pool 103 on the left. The three are arranged side by side and form a whole. The lower part of the front of the phosphating pool 101, the cleaning pool 102, and the saponification pool 103 is provided with a drain pipe 24, which is used to regularly discharge the sewage in the phosphorus soap pool 1;

[0039] The inner cavity at the lower portion of the movable sleeve 81 is hollow, and the hollow hole is located directly above the push rod 74 .

[0040] Specifically, a power connection piece 91 is fixedly connected to the inner cavity of the junction box 9. A wire 16 is connected between the input end of the motor 13 and the power connection piece 91. The wiring switch 12 is a "day"-shaped power connection component. The right side of the wiring switch 12 is movably placed on the power connection piece 91. Half of the wiring switch 12 close to the upper lever 84 and the lower lever 85 is made of insulating material, and half of the wiring switch 12 close to the junction box 9 is made of metal material.

[0041] Furthermore, positive and negative wiring ports 121 are opened on the right part of the wiring switch 12. The positive and negative wiring ports 121 are used to connect the live wire and the neutral wire of the power supply line. The left part of the wiring switch 12 is sleeved between the upper lever 84 and the lower lever 85, and the upper lever 84 and the lower lever 85 are symmetrically arranged. The output end of the motor 13 is connected to the upper end of the rotating shaft 14, and the fan blade 15 is fixedly installed on the rotating shaft 14. The movable sleeve 81 penetrates and is movably connected to the inner cavity of the rear part of the mounting plate 6. A spring 86 is fixedly connected between the outer ring of the lower part of the movable sleeve 81 and the bottom of the mounting plate 6. The spring 86 is provided to make the upper end of the ejector rod 74 separate from the movable sleeve 81 when the hanging basket moves downward again in the next process. At this time, the spring 86 will drive the movable sleeve 81 to reset, and then the linkage rod 83, the upper lever 84, and the lower lever 85 will reset, and then drive the wiring switch 12 to reset, disconnect the power supply of the motor 13, and stop the operation of the air blowing mechanism. When the hanging basket 73 is lifted, it will start automatically again.

[0042] During specific use, before performing phosphating and saponification treatment on large-sized metal fasteners, it is first necessary to undergo shot peening pretreatment - degreasing - hot water washing - cold water washing treatment, and then place the metal fasteners in the hanging basket 73 to start phosphating treatment. The pressing cylinder 71 drives the telescopic rod 72 downward and then带动 the hanging basket 73 and the metal fasteners in the hanging basket 73 into the phosphating tank 101 filled with phosphating solution. The phosphating solution enters the hanging basket 73 through the water inlet hole 76 of the hanging basket to soak the metal fasteners, and a phosphating film will be formed on the surface of the metal fasteners. The phosphating film can improve the weather resistance of the metal fasteners. After soaking for 10 minutes, the hanging basket 73 is lifted by the pressing cylinder 71. During the lifting process, the ejector rod 74 moves upward together with the hanging basket 73. The upper end of the ejector rod 74 will insert into the inner cavity of the movable sleeve 81 and push the movable sleeve 81 upward, while compressing the spring 86. When the movable sleeve 81 is pushed up, the upper linkage rod and the two groups of levers move upward synchronously. At this time, the lower lever 85 will带动 the left end of the拨动接线开关 12 to flip upward, and the right end of the wiring switch 12 will flip downward to contact the power connection piece 91. Since the output end of the motor 13 is connected to the power connection piece 91 through a wire, the power supply of the motor 13 is turned on and started at this time,带动 the rotating shaft 14 to rotate, and then带动 the fan blade 15 to rotate, which can accelerate the air flow. The rapidly flowing air can accelerate the drying of the metal fasteners, and then improve the efficiency of hardening the phosphating film. Then it enters the water washing process and the saponification process. Repeating the above steps can improve the overall efficiency of phosphating and saponification of metal fasteners. Example

[0043] On the basis of Example 1, a first power mechanism is arranged at the rear of the longitudinal slide rail 3, and the first power mechanism includes a first motor 17. The output end of the first motor 17 is connected to a first screw rod 18, and the first screw rod 18 passes through the inner cavity of the fixed block installed on the top of the first slider 31; the second power mechanism is arranged at the right part of the bottom of the transverse slide rail 4, and the second power mechanism includes a second motor 19. The output end of the second motor 19 is connected to a second screw rod 20, and the second screw rod 20 passes through the inner cavity of the lower part of the second slider 5, and the lower part of the transverse slide rail 4 is also provided with a slide rod 21, and the slide rod 21 is symmetrical with the second screw rod 20 and also passes through the inner cavity of the lower part of the second slider 5.

[0044] When used specifically, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,and Figure 6 As shown, during the above-mentioned process of phosphosaponification treatment of the metal fasteners, position adjustment is required. The first motor 17 can drive the first screw rod 18 to rotate and then drive the first slider 31 to move forward and backward along the longitudinal slide rail 3. The second motor 19 can drive the second screw rod 20 to rotate and then drive the second slider 5 to move horizontally, and then adjust the position of the lifting basket mechanism, the power self-starting mechanism, and the blower mechanism. The lifting basket mechanism, the power self-starting mechanism, and the blower mechanism move synchronously. Example

[0045] Based on Example 1 and Example 2, the protective cover 22 is fixedly mounted on the front of the top of the mounting plate 6, and the protective cover 22 is sleeved on the periphery of the motor 13. The protective cover 22 is a closed cover body, and a group of ventilation pipes 23 are fixedly connected to the side of the protective cover 22, and the lower end of the ventilation pipes 23 extends to the lower part of the fan blades 15.

[0046] Furthermore, there are snap-in grooves on both sides of the front of the hanging basket 73, and the inner cavity of the snap-in groove is movably snap-in with a baffle 75. The rear part of the bottom of the inner cavity of the hanging basket 73 is an arc surface, and water inlet holes 76 are provided on the bottom and both sides of the hanging basket. When the metal fasteners have undergone all the process treatments, you only need to pull out the baffle 75, and the internal metal fasteners will slide out along the arc surface of the bottom of the inner part of the hanging basket 73. At this time, you only need to place a collection box at the bottom of the hanging basket for collection, which is more convenient to use.

[0047] When used specifically, Figure 1 and Figure 2As shown, in the above-mentioned embodiment 1, when the motor 13 of the blowing mechanism drives the fan blades 15 to rotate for blowing, the rapid flow of air can extract the heat generated by the motor 13 inside the protective cover 22 when it is working, thereby increasing the temperature of the air flow blown to the hanging basket, and further accelerating the saponification of the metal fasteners and the drying speed after washing.
