Description

Technical Field

[0001] The invention belongs to the technical field of surface treatment equipment, in particular to a metal surface treatment equipment. Background Art

[0002] With the advancement of science and technology, the different requirements for metal material performance have led to the rapid development of metal surface treatment technology. According to its treatment process, common metal surface treatment technologies include electroplating, anodizing, micro-arc oxidation, electrophoresis, PVD vacuum plating, powder spraying, metal wire drawing and other processes, and according to the treatment effect, it can be divided into passivation, coating, phosphating, etc.

[0003] Most of the metal surface treatment processes are carried out by immersing in chemical reagents, such as pickling process, passivation process, etc. During immersion, the reaction between chemical reagents and metal workpieces can achieve dissolution, stripping, coating and other effects. At the same time, the combined use of multiple processes can promote each other. For example, before the passivation treatment of stainless steel plates, the degreasing process and pickling process will be carried out first to remove oil stains and rust on the surface of the metal workpiece, and then the surface of the metal workpiece will be modified by the passivation liquid to enhance the final passivation effect of the component. However, in the batch operation of the metal surface treatment process of chemical reagent immersion, due to the need to ensure uniform contact between the chemical reagent and the surface of the metal workpiece, the metal workpieces need to be separated from each other during the surface treatment, thereby preventing the problem of incomplete surface treatment or inconsistent surface treatment degree. When the metal workpieces are operated one by one and in batches, most of them are suspended or supported by conveying equipment and placed in the treatment liquid, thereby realizing the assembly line treatment of the metal workpiece.

[0004] When metal workpieces are suspended or supported by related technologies, most of them are done through hooks, clamps or mesh boxes, which not only requires the workpieces to be operated one by one, resulting in low efficiency and high labor workload, but also the contact between the metal workpiece and the hooks and supporting plates hinders the contact between the metal workpiece and the reaction liquid, and also has a certain impact on the uniformity of the surface treatment of the metal workpiece.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

[0006] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the present invention proposes a metal surface treatment device.

Not only during the movement, in conjunction with gravity, the movement effect of the metal workpiece in the grid space is enhanced, and the probability of the metal workpiece contacting the filter plate 24 and the separator plate 25 for a long time is reduced, but the circular motion can also cause the metal workpiece to contact the treatment liquid at different depths in the processing tank 2, thereby reducing the stratification of the reaction solution in the processing tank 2 and the influence on the surface treatment effect of the metal workpiece.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 4As shown, a metal surface treatment device described in the present invention includes a modified cell body 1, on which a uniformly distributed treatment tank 2 is opened, and the treatment tank 2 is filled with a reaction solution; a conveying component, the conveying component includes a loading platform 11 and a unloading platform 12, and the loading platform 11 and the unloading platform 12 are respectively fixedly connected to the two ends of the modified cell body 1; and also includes a batch transmission component, the batch transmission component is installed on the modified cell body 1, and the batch transmission component cooperates with the conveying component to separate and transport the workpieces input by the loading platform 11 to the unloading platform 12; the batch transmission component includes a conveying wheel shaft 21, and the conveying wheel shaft 21 is rotatably installed in the treatment tank 2, and a transmission groove 22 is opened on one side of the modified cell body 1. The conveying wheel shafts 21 all extend into the transmission groove 22; a driving motor 23, the driving motor 23 is fixedly mounted on the modification cell body 1, and a plurality of the conveying wheel shafts 21 are connected to each other with a transmission, and one of the conveying wheel shafts 21 is fixedly connected to the rotating shaft of the driving motor 23; a filter plate 24, a filter plate 24 is mounted on the conveying wheel shaft 21, and the filter plates 24 are evenly arranged along the circumferential direction of the conveying wheel shaft 21; a separator 25, a separator 25 is mounted on the conveying wheel shaft 21, and the separator 25 is evenly arranged along the axial direction of the conveying wheel shaft 21; a fine-tuning component, the fine-tuning component is mounted on the modification cell body 1, and the fine-tuning component cooperates with the batch transmission component to adjust the angle of the workpiece to enhance the uniformity of contact between the workpiece and the reaction solution;When the metal workpiece is surface modified by immersing it in chemical reagents, the metal workpiece is placed on the loading platform 11 by a conveyor belt device or manually. Under the action of gravity, the metal workpiece slides downward along the inclined surface of the loading platform 11, and then slides into the processing tank 2 on the modification tank body 1. Due to the setting of the batch transmission component, the structure composed of the conveying wheel shaft 21, the filter plate 24 and the separation plate 25 is installed in the processing tank 2, and the filter plate 24 and the separation plate 25 are arranged in different directions and installed on the conveying wheel shaft 21. The filter plate 24 and the separation plate 25 cooperate with each other to form a uniformly distributed lattice structure on the conveying wheel shaft 21. When the metal workpiece slides into the processing tank 2, it enters the filter plate 24 and the separation plate 25. In the lattice space formed by the plate 25, in the early stage of equipment manufacturing, by selecting filter plates 24 and separation plates 25 of different sizes, the size of the lattice space can be effectively adjusted, thereby limiting the number of metal workpieces entering the lattice space. While placing the metal workpiece on the upper feeding platform 11, the drive motor 23 is started, and the output shaft of the drive motor 23 rotates, thereby driving the conveying wheel shaft 21 to rotate at a uniform speed in the processing tank 2. The uniform rotation of the conveying wheel shaft 21 causes the lattice space formed by the filter plate 24 and the separation plate 25 to rotate continuously, thereby causing the workpieces sliding in sequence on the feeding platform 11 to enter different lattice spaces respectively, and with the structures such as the partitions installed on the feeding platform 11, it can effectively The metal workpieces are separated and isolated. At the same time, when the conveying wheel shaft 21 cooperates with the filter plate 24 and the separation plate 25 to drive the metal workpiece to move, as the metal workpiece gradually moves to the bottom of the processing tank 2, the reaction solution filled in the processing tank 2 contacts the metal workpiece and gradually submerges the metal workpiece. Since the filter plate 24 is a plate-shaped structure formed by a metal filter mesh, there are a large number of tiny gaps on its surface. Therefore, when the filter plate 24 rotates in the processing tank 2, the reaction solution can freely pass through the filter plate 24. As the rotation continues, under the restriction of the grid space, the metal workpiece makes an arc-shaped motion in the processing tank 2. During the arc-shaped motion of the workpiece, the metal workpiece is continuously affected by gravity, which causes the metal workpiece to move. The movement of the metal workpiece in the grid space can not only change the angle of the metal workpiece, but also make the metal workpiece contact with the reaction solution of different depths in the processing tank 2 during the movement, so that the metal workpiece and the reaction solution in the processing tank 2 are more uniformly contacted. Subsequently, when the metal workpiece moves to the other side of the processing tank 2 driven by the filter plate 24 and the separation disk 25, the metal workpiece moves to another adjacent processing tank 2 under the pushing and guiding action of the filter plate 24, and contacts with the reaction solution in another processing tank 2 under the limiting and pushing action of the conveying wheel shaft 21, filter plate 24 and separation disk 25 in the adjacent processing tank 2, thereby realizing the multi-process automated processing of the metal workpiece. ;

[0037] The present invention forms a grid space on the conveying wheel shaft 21 by setting a batch conveying component, using the filter plate 24 and the separator plate 25, and then uses the grid space to receive the metal workpieces one by one, and then divides the workpieces into batches and separates them, thereby reducing the probability of the metal workpieces colliding with and influencing each other during movement. On the other hand, the conveying wheel shaft 21 cooperates with the filter plate 24 and the separator plate 25 to drive the metal workpiece to make an arc-shaped movement in the processing tank 2. Not only during the movement, with the help of gravity, the movement effect of the metal workpiece in the grid space is enhanced, and the probability of the metal workpiece contacting the filter plate 24 and the separator plate 25 for a long time is reduced, but the circular motion can also cause the metal workpiece to contact the treatment liquid of different depths in the processing tank 2, thereby reducing the stratification of the reaction solution in the processing tank 2 and the influence on the surface treatment effect of the metal workpiece. At the same time, the batch conveying components in multiple processing tanks 2 are automatically docked, so that the metal workpiece can automatically perform multiple process operations, further reducing the labor intensity of the staff.

[0038] As a preferred embodiment of the present invention, the upper surface of the modified tank body 1 is designed to be inclined, and the multiple processing tanks 2 are arranged in a step-shaped manner. The loading platform 11 and the unloading platform 12 are respectively connected to the top and bottom ends of the upper surface of the modified tank body 1, and the height of the processing tank 2 close to the unloading platform 12 is less than the center height of the corresponding conveying wheel shaft 21;

[0039] By making the upper surface of the modification tank body 1 inclined, multiple processing tanks 2 are distributed in a stepped manner on the modification tank body 1. After the loading platform 11 guides the metal workpiece to the highest-end processing tank 2, the metal workpiece moves in a circular arc in the processing tank 2 and then moves to the next processing tank 2 again under the drive of the batch conveying component. At this time, the stepped processing tanks 2 can effectively reduce the difficulty of the metal workpiece moving to the next processing tank 2 in turn. At the same time, there is a height difference between two adjacent processing tanks 2, which can reduce the probability of the reaction solution in the next processing tank 2 splashing into the previous processing tank 2.

[0040] As a preferred embodiment of the present invention, an auxiliary tank 3 is provided inside the modification tank body 1, and the auxiliary tank 3 corresponds to the treatment tank 2 one by one, and the auxiliary tank 3 is designed to be in conduction with the treatment tank 2;

[0041] When metal workpieces are subjected to surface treatment, solid residues will be generated in many treatment processes, such as rust and dust detached during pickling. Therefore, as the number of processed metal workpieces continues to increase, the impurity content in the reaction solution in the treatment tank 2 will increase. During the continuous rotation of the conveying wheel shaft 21, the filter plate 24 performs a circular motion in the treatment tank 2 to filter the reaction solution in the treatment tank 2, thereby intercepting solid impurities. As the filter plate 24 continues to move, when the filter plate 24 moves to the connection point between the auxiliary tank 3 and the treatment tank 2, under the action of gravity, the solid impurities intercepted on the filter plate 24 move into the auxiliary tank 3 and gradually settle at the bottom of the auxiliary tank 3, thereby achieving continuous filtration of the reaction solution in the treatment tank 2 and reducing the influence of solid impurities shed from the metal workpiece on the surface treatment of the metal workpiece.

[0042] As a preferred embodiment of the present invention, the side wall of the treatment tank 2 close to the unloading platform 12 is designed to be connected with the auxiliary tank 3, and the auxiliary tank 3 is located in the side wall opening design of the modification tank body 1, and a rubber plug is installed at the opening of the auxiliary tank 3;

[0043] Since the plurality of treatment tanks 2 are distributed in a stepped manner on the inclined surface of the reaction tank body, when the reaction solution is filled into the treatment tank 2 or the rotating filter plate 24 pushes the reaction solution, it is very easy to cause the reaction solution to flow into the next treatment tank 2. Therefore, by opening the auxiliary tank 3 on the side wall of the modified tank body 1, when the reaction solution is poured into the treatment tank 2 or the filter plate 24 moves in the treatment tank 2, when the liquid level of the solution reaches the opening of the auxiliary tank 3, the reaction solution flows into the auxiliary tank 3 under the action of gravity, thereby realizing the restriction of the liquid level of the reaction solution in the treatment tank 2. On the one hand, limiting the liquid level of the reaction solution in the treatment tank 2 can reduce the probability of the reaction solution flowing into the next treatment tank 2. At the same time, when the filter plate 24 pushes the metal workpiece to move into the next treatment tank 2, the metal workpiece can be filtered, further reducing the probability of the reaction solution in the previous treatment tank 2 entering the next treatment tank 2. On the other hand, when the excess reaction solution flows into the auxiliary tank 3, it can flush the solid impurities collected in the auxiliary tank 3 and discharge them through the opening of the auxiliary tank 3, so as to facilitate the cleaning of the auxiliary tank 3.

[0044] As a preferred embodiment of the present invention, the fine-tuning assembly includes a spray pipe 4, and the bottom of the treatment tank 2 is fixedly installed with uniformly distributed spray pipes 4;

[0045] Water pump 41, the modification tank body 1 is equipped with uniformly distributed water pumps 41, the water pumps 41 correspond to the treatment tanks 2 one by one, and the injection pipes 4 are all connected to the output ends of the water pumps 41;

[0046] A liquid storage cavity 42 is provided inside the modified cell body 1, and the suction end of the water pump 41 extends into the liquid storage cavity 42;

[0047] When the metal workpiece is acted upon by the conveying wheel shaft 21, the filter plate 24 and the separation plate 25, and performs an arc motion in the processing tank 2, the fine-tuning component gives the metal workpiece a continuous driving force to accelerate the movement rate of the metal workpiece in the grid space. Specifically, when the equipment is started, the water pump 41 is started, and the water pump 41 continuously extracts the reaction solution in the liquid storage chamber 42 through the pipeline, and after the reaction solution is further pressurized, it is transported to the injection pipe 4 through the pipeline, and the reaction solution flows into the processing tank 2 through the opening of the injection pipe 4, and gives the metal workpiece located in the processing tank 2 an impact force, and cooperates with the metal workpiece to The circular motion in the processing tank 2 enhances the movement effect of the metal workpiece, thereby causing a greater change in the angle between the metal workpiece and the filter plate 24, thereby reducing the probability of dead angles in the surface treatment of the metal workpiece. At the same time, by adjusting the power of the water pump 41, the impact force of the water flow sprayed in the injection pipe 4 on the metal workpiece can be adjusted. The size of the driving force given to the metal workpiece by the liquid flow can be adjusted. In addition, when the metal workpiece is subjected to surface treatment operations such as pickling and water washing, the cleaning effect on the metal workpiece can be effectively enhanced by adjusting the impact force of the liquid flow, thereby enhancing the flexibility of adjusting the processing effect of the metal workpiece.

[0048] As a preferred embodiment of the present invention, the filter plates 24 are all arc-shaped, and the openings of the injection pipes 4 are all oriented toward the center of the conveying wheel shaft 21;

[0049] By setting an arc-shaped filter plate 24, when the metal workpiece moves into the grid space and then moves into the processing tank 2, the arc-shaped filter plate 24 can effectively reduce the contact area with the metal workpiece. At the same time, the arc-shaped filter plate 24 can cooperate with the circular motion, which can further enhance the rotation probability of the metal workpiece in the processing tank 2. The opening direction of the injection pipe 4 is toward the center of the conveying wheel shaft 21, so that the metal workpiece can be given impact forces at different angles during the circular motion of the metal workpiece, thereby further enhancing the impact effect on the metal workpiece.

[0050] As a preferred embodiment of the present invention, the filter plates 24 are rotatably connected with rollers 43 evenly distributed;

[0051] By rotating the rollers 43 evenly distributed on the filter plate 24, the friction between the filter plate 24 and the metal workpiece can be effectively reduced, while reducing the contact area between the metal workpiece and the filter plate 24, thereby reducing the difficulty of the metal workpiece moving and converting the angle in the grid workpiece.

[0052] As a preferred embodiment of the present invention, the auxiliary tank 3 is designed to be in communication with the liquid storage chamber 42, and a fine filter 31 is installed at the communication point between the auxiliary tank 3 and the liquid storage chamber 42;

[0053] By designing the auxiliary tank 3 to be connected with the liquid storage chamber 42, the reaction solution sprayed from the injection pipe 4 causes the liquid level in the treatment tank 2 to rise, and the excess reaction solution flows into the auxiliary tank 3 and enters the liquid storage tank again through the auxiliary tank 3. At the same time, in the process of the reaction solution flowing into the liquid storage tank, the reaction solution is filtered by the fine filter 31, thereby intercepting solid impurities in the auxiliary tank 3, and the reaction solution with a lower impurity content is circulated to the treatment tank 2 again through the water pump 41. The reaction solution is recycled, which can not only effectively improve the utilization rate of the reaction solution, but also accelerate the rate at which the impurities in the treatment tank 2 move into the auxiliary tank 3 during the circulation of the reaction solution, thereby maintaining the purity of the reaction solution in the treatment tank 2.

[0054] As a preferred embodiment of the present invention, the fine filter 31 is designed to be inclined;

[0055] By setting the fine filter 31 at an angle, the fine filter 31 guides the residue under the flushing effect of the reaction solution, causing the solid impurities to move to the bottom of the auxiliary tank 3, thereby enhancing the collection and gathering effect of the solid impurities.
