Description

TECHNICAL FIELD

[0002] With the year-by-year improvement of the light weight and safety standard requirements of automobile, the use proportion of ultra-high strength steel plate gradually improves. After hot stamping piece is shot blasted, it must be immediately coated with rust preventive oil, otherwise it will be quickly oxidized again. The traditional oiling method is to spray rust preventive oil manually. Manual operation has the following problems: low efficiency, high cost and uneven spraying. Therefore, the spraying process is gradually mechanized. In order to increase the uniformity and smoothness of the coating, the mechanical coating is carried out in multiple layers, i.e., the material surface is first coated, and then the second layer is coated after the first layer of coating material is dried. This process is repeated. Since the oil has a certain moisture, if it is dried naturally without the aid of other technical means, the drying efficiency of the oil is slow due to the difference in gas flow rate. If a fan or other technical means is used, it may affect the coating quality of the materials in other workstations during the drying process. For example, the above-mentioned problems exist in the patent No. CN201921924947.6. Since there is no drying process during coating, the oil may gradually accumulate on the surface of the material, which may easily cause the material surface to form a dripping phenomenon, i.e., multiple convex points are formed on the surface, which affects the surface smoothness of the product.

[0028] The spraying assembly 6 comprises a base 7, a pressure booster 8 and a spray head 9, the base 7 is installed in the oiling chamber 1, the pressure booster 8 is installed on the base 7, and a plurality of spray heads 9 are arranged on the pressure booster 8; the material can be oiled on both sides, and the material can be sprayed and oiled multiple times, so that the uniformity of oiling is ensured, and the material accumulation is reduced, so that the convex point is formed.

[0029] The number of the plurality of spray heads 9 is at least three, and the spray heads 9 are arranged from top to bottom; the area of the material can be set, and the material cannot be completely sprayed and oiled in the spraying process.

[0030] The material clamping mechanism 17 comprises a rotating column 19, a second gear 20, a torsional spring 21 and a clamping assembly 22, the rotating column 19 is rotatably connected to the vertical rod 15, the second gear 20 is installed on the rotating column 19, the second gear 20 is meshingly connected with the second rack 18, the torsional spring 21 is sleeved on the second gear 20, and the clamping assembly 22 is installed on the rotating column 19; the material can be fixed and conveyed, and when the material moves away from one oiling mechanism 2 to another oiling mechanism 2, the material can be rotated, so that the surface material drying is accelerated.

[0031] The clamping assembly 22 is two groups, and the two groups of clamping assemblies 22 are arranged at both ends of the rotating column 19. The material is located between the two clamping assemblies 22, so that the material is clamped, and the surface of the material is prevented from being blocked during oiling.

[0032] Working principle:

[0033] Reference Figure 5 When the device is oiled, the material needs to be pushed to move in the oiling chamber 1, so that the material moves to the oiling nozzle 9, and the surface of the material is oiled by the nozzle 9, Figure 5 for the work of oiling;

[0034] Since the oiling work is generally carried out in multiple oiling, in order to ensure the uniformity of oiling, the following operation steps will be carried out:

[0035] Reference Figure 5 The material is arranged on the rotating column 19, and the torsional spring 21 is in an initial state without force at this time;

[0036] Reference Figure 4 When the conveying assembly 14 pushes the rotating column 19 to move in the oiling chamber 1, the material will gradually move to the two groups of nozzles 9 for spraying, and in the moving process, the first rack 16 will first engage with the first gear 13 in the left oiling mechanism 2, and with the pushing of the conveying mechanism, reference Figure 3 The first rack 16 will first drive the first gear 13 to rotate, and the first gear 13 will drive the rotating pipe 11 to rotate in the fixed pipe 10. At this time, the through hole 12 on the fixed pipe 10 and the through hole 12 on the rotating pipe 11 are through, and when the through holes 12 of the two are completely through, Figure 4 The liquid in the liquid storage tank 3 enters the booster 8 through the fixed pipe 10 and the rotating pipe 11, and then is sprayed out through the nozzle 9 (the material is located between the multiple nozzles 9, reference Figure 4 ), multiple nozzles 9 form a first layer of spraying on the material surface. When the first rack 16 is separated from the first gear 13, the two through holes 12 are again misaligned, the flow control mechanism 4 is closed, and the material is away from the nozzle, which can avoid waste of oil;

[0037] When the first layer of spraying is finished, the conveying assembly 14 pushes the material to move to the next oiling mechanism 2 (i.e. Figure 4 the position of the first gear 13 on the right side in the middle), and the distance formed between the two oiling mechanisms 2 will make the material rotate, and through the rotation of the air flow, the oil film of the first layer of spraying is drained and flattened;

[0038] The specific rotating process is, reference Figure 4, with the second gear 20 to the right side movement, when the second rack 18 and the second gear 20 mesh, the thrust of the conveying assembly 14 makes the second gear 20 under the drive of the second rack 18 rotation, thereby driving the rotating column 19 positive rotation on the vertical rod 15, the rotating column 19 positive rotation while the torsion spring 21 is compressed, and the rotating column 19 rotates in the process, through the flow of air on the surface of the material, the flowing air acts on the surface of the material, in turn accelerates the first layer of oil on the surface of the material gradually air dry; secondly, with the continuous pushing of the conveying assembly 14, when the second rack 18 and the second gear 20 disengaged, the torsion spring 21 drives the rotating column 19 quickly reverse rotation, at this time the flowing air again on the material surface oil secondary air dry, thereby avoiding the material in the next side smearing, its surface oil is not dry and too much, resulting in oil accumulation;

[0039] With the continuous pushing of the conveying assembly 14, when the material moves to another oiling mechanism 2, the oiling mechanism 2 again repeats the above oiling action, thereby making it to the material for secondary oiling, at this time the first oiling material has gradually air dry, in turn will not and the second oiling material form the accumulation state, thereby can effectively avoid the material in the process of oiling appear multiple accumulation, thereby forming the convex point case, further guarantee the quality and effect of its oiling.
