Description

Technical Field

[0001] The invention belongs to the technical field of passivation and relates to a drying pre-treatment device for alloy workpieces. Background Art

[0002] Passivation refers to the process of metal being oxidized by strong oxidants or electrochemical methods to make the surface inactive, which is a method of transforming the metal surface into a state that is not easily oxidized and slowing down the corrosion rate of the metal. In addition, the phenomenon of an active metal or alloy, in which the chemical activity is greatly reduced and becomes a precious metal state, is also called passivation.

[0003] At present, many parts on the market need to be passivated, such as some parts in trains. Before passivation, the workpiece surface needs to be deburred, and then ultrasonic cleaning (chemical cleaning, removal of surface oil, etc.) is used. After the chemical cleaning is completed, rinse with clean water, then use passivation liquid treatment, and finally dry to complete the passivation of the workpiece. In order to improve the drying efficiency, workers usually use a blowpipe to blow water on the workpiece manually between passivation and drying to speed up the drying process.

[0004] Since the shapes of many parts are not simple plates or columns, but more complex shapes, it takes a long time to use a paint spray tube to blow them comprehensively.

The end of the adjusting portion 29 abuts against the fixing portion 28. A plurality of adjusting portions 29 are provided, and different adjusting portions 29 have different lengths.

[0052] A cylindrical unlocking hole 31 is formed at the free end of the adjusting portion 29, a first anti-rotation hole 32 penetrating the adjusting portion 29 is formed at one end of the unlocking hole 31, a second anti-rotation hole 33 matching the first anti-rotation hole 32 is formed in the threaded hole, the cross sections of the first anti-rotation hole 32 and the second anti-rotation hole 33 are both rectangular, and an anti-slip magnet 34 is disposed in the second anti-rotation hole 33;

[0054] The present invention provides a drying pretreatment equipment for alloy workpieces. After the workpieces are passivated and cleaned, the workers first place the cleaned workpieces on the conveyor belt 3, or the workpieces are conveyed by other conveyor belts or moved to the conveyor belt 3 by a robot. Then, the first driving mechanism drives the first support roller 2 to rotate, and at the same time, the workpiece is driven forward on the conveyor belt 3 through the conveyor belt 3; at the same time, the blower blows high-pressure air into the first blowing pipe 4, and the high-pressure air is blown upward through the first blowing head 5. At the same time, since the conveyor belt 3 is porous, the compressed air can act on the lower side of the workpiece after passing through the conveyor belt 3, so that the residual water at the bottom of the workpiece can be better blown away. The first blowing pipe 4 has multiple first blowing pipes, so that when the workpiece passes through each first blowing pipe 4, it can be blown away, so that the water blowing effect is better, and the subsequent drying can be more efficient and the use effect is better. In this application, the shape of the workpiece to be blown dry is preferably as follows: Fig. 9 As shown, the top is flat and the bottom is a more complex shape (specifically, parts on a train).

[0055] During transmission, the driving motor 16 drives the driving rod 17 to rotate, and the driving rod 17 drives the driven gear 19 to rotate through the driving gear 18. At the same time, the driven gear 19 drives a first support roller 2 to rotate, and then drives the transmission belt 3 and another first support roller 2 to rotate. At the same time, the driving wheel 25 on the side of the driving gear 18 drives the driven wheel 24 to rotate through the transmission belt 26 (such as a belt or a chain), and at the same time, the driven wheel 24 drives a second support roller 9 to rotate through the linkage rod 23, and at the same time, it also drives the adjustment belt 10 and another second support roller 9 to rotate. The two first support rollers 2 and one of the second support rollers 9 are both provided with holes in the middle, and are movably sleeved on the first bracket 1 and the second bracket 8 respectively. One end of the hole in the middle of the other second support roller 9 is rotatably connected to the second support portion 21, and the other end is fixedly connected to the linkage rod 23, that is, when the linkage rod 23 rotates, it can drive the second support roller 9 to rotate. At the same time, the linkage rod 23 moves through one end of an anti-fall plate 12, so that one end of the anti-fall plate 12 is supported by the second bracket 8, and the other end is supported by the linkage rod 23, so that its position can be kept stable.

[0056] When the workpiece is placed on the conveyor belt 3, there is no turning belt 10 above it to block it. At the same time, when the workpiece is taken down after being blown dry, there is no turning belt 10 above it to block it, so that the practical effect is better.

[0057] After the workpiece is placed on the conveyor belt 3, it is transported forward by the conveyor belt 3 and guided by the guide part 13, so that it can stably enter between the two anti-fall plates 12, and can be limited by the anti-fall plates 12 during the movement without falling.

[0058] The first blowing head 5 below blows air upward to dry the water on the bottom of the workpiece, and at the same time the second blowing head 15 below blows air downward (the second blowing pipe 14 is also connected to an air pump), so that the upper surface of the workpiece can also be blown. That is, the present application can be applied to both Fig. 9 It can be the artifact in or other artifacts.

[0059] Moreover, the compressed air blown out by the first blowing head 5 and the second blowing head 15 only passes through one layer of the conveyor belt 3 or the turning belt 10, so that the air can better act on the workpiece; secondly, the anti-fall plate 12 and the support plate 7 can also play a blocking role for the air, so that the air can better pass through the conveyor belt 3 or the turning belt 10, reducing the amount of air flowing away from the side, and ensuring the water blowing effect of the workpiece from the side.

[0060] At the same time, when the workpiece is moving, the bottom of the steering belt 10 is higher than the workpiece, and the free end of the steering rod 11 will not act on the conveyor belt 3; but the side of the steering rod 11 can act on the side of the workpiece, so that when the conveyor belt 3 brings the workpiece to the downstream direction, the steering rod 11 will act on the side of the workpiece from the upstream, so that the workpiece can rotate at an angle under the dual action of the conveyor belt 3 and the steering rod 11, so that the workpiece can be misaligned with the holes (for air passage) on the conveyor belt 3 and the steering belt 10, so that a larger area of ​​the workpiece can be affected by the airflow, thereby making the water blowing effect of the entire workpiece better. Among them, since the distance between the steering rod 11 and the middle of the steering belt 10 is large and the distance from the edge is small, the steering rod 11 mainly acts on the edge or side of the workpiece, so that the swing amplitude of the workpiece is larger and the swing effect is also greater, and it can also prevent the steering rod 11 from applying too large a driving effect to the workpiece, that is, the steering rod 11 can be better separated from the workpiece, which is convenient for the workpiece to move normally downstream. Moreover, the projections of the first air blowing pipe 4 and the second air blowing pipe 14 in the vertical direction are in a staggered state, which can effectively prevent the upward and downward airflows from affecting each other, thereby ensuring the water blowing effect.

[0061] Different workpieces have different thicknesses, so the length requirements for the entire steering rod 11 are also different. For example, if the workpiece is thin, a longer steering rod 11 is required; but if the workpiece is thick, it means that its mass is also large. If a longer steering rod 11 is still used at this time, it is easy to generate excessive force between the steering rod 11 (in fact, only a slight adjustment of the workpiece angle is needed), thereby causing excessive force between the connecting plate 27 and the steering belt 10, resulting in poor use effect. Therefore, it is necessary to adjust the length of the steering rod 11 according to actual needs.

[0062] When adjusting, first use a vise or other tool to reach into the unlocking hole 31 and clamp it on the removal part 36, then take out the removal part 36, and then rotate the adjustment part 29 to separate the adjustment part 29 from the fixed part 28. Then select the adjustment part 29 of the required length, and thread the threaded part 30 of the adjustment part 29 with the threaded hole, and finally insert the anti-rotation rod 35 into the first anti-rotation hole 32 and the second anti-rotation hole 33, and make the end of the anti-rotation rod 35 magnetically attracted to the anti-slip magnet 34, so as to complete the adjustment of the length of the adjustment rod 11. In the subsequent use process, the anti-rotation rod 35 can prevent the adjustment part 29 and the fixed part 28 from rotating relative to each other, so as to ensure the stable position of the adjustment part 29 and the fixed part 28.

[0063] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
