Description

Technical Field

[0001] The present invention relates to the technical field of passivation treatment, and particularly to a device for passivating the surface of fittings. Background Art

[0002] Passivation refers to the process in which a metal is oxidized by a strong oxidant or an electrochemical method to make the surface become an inactive state, that is, the passivation process. It is a method to make the metal surface transform into a state that is not easily oxidized and delay the corrosion rate of the metal. In addition, the phenomenon that a chemically active metal or alloy becomes a noble metal state with greatly reduced chemical activity is also called passivation.

[0003] Therefore, in the production of mechanical fittings, the passivation process is also used to achieve corrosion resistance. However, the solvent used for passivation has strong oxidizing properties and is harmful to the health of operators. Therefore, an automated device is needed to implement the passivation process. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a device for passivating the surface of fittings, including a frame. A passivation container is fixedly connected to the inner side of the lower part of the frame. The passivation container is used for the treatment solvent for passivation treatment, and the workpiece is placed in the passivation container for passivation operation.

[0005] First guide rails are fixedly connected to both sides of the middle part of the frame. An opening is provided in the middle of the first guide rail, and a second guide rail is connected in the opening. Grooves are provided on the opposite sides of the first guide rail and the second guide rail. The device further includes a material frame, and the upper edge of the material frame is fitted and slidably engaged in the card slots. The first guide rail and the second guide rail are provided to enable the material frame to move along the first guide rail and the second guide rail, which is beneficial to the conveyance of the workpiece for passivation treatment.

[0006] A pressure plate is arranged above the passivation container. Connecting rods are fixedly connected to both sides of the pressure plate. The lower ends of the connecting rods are fixedly connected to the second guide rail. An upper fixing plate is fixedly connected to the upper end of the frame. A pneumatic cylinder is fixedly connected to the middle of the upper end of the upper fixing plate. The output end of the pneumatic cylinder is fixedly connected to a telescopic rod. The lower end of the telescopic rod is fixedly connected to the pressure plate. When the material frame is located on the second guide rail, the pneumatic cylinder is started at this time, and the telescopic rod extends, causing the material frame to descend, so that the material frame is immersed in the passivation container, thereby realizing the passivation operation of the workpiece.

[0007] Preferably, support feet are fixedly connected to the four corners of the lower end of the frame. The support feet support and fix the frame.

[0008] Preferably, a drainage platform is inclinedly arranged on one side of the passivation container. After passivation treatment, the air cylinder is started and the telescopic rod retracts to lift the material frame. The drainage platform is provided, that is, the material frame just after passivation treatment is moved to the drainage platform for drainage operation, and the dripping treatment solvent flows into the passivation container along the inclined drainage platform.

[0009] Preferably, one end of the first guide rail extends above the drainage platform, and an inclined support rod is fixedly connected to the middle of the frame. The upper end of the inclined support rod is fixedly connected to the extended first guide rail. The inclined support rod is used to support the extended first guide rail.

[0010] Preferably, a push-pull rod is fixedly connected to the upper end of the buckle plate. The push-pull rod penetrates upward through the upper fixing plate, and a baffle is fixedly connected to the upper end of the push-pull rod. A spring is sleeved on the push-pull rod. One end of the spring abuts against the upper end of the upper fixing plate, and the other end abuts against the baffle. The setting of the spring and other structures is that when the material frame descends, the spring is compressed to store elastic potential energy, and at the same time, the descending speed of the material frame is inhibited to avoid splashing of the treatment solvent in the passivation container. When the material frame ascends, the spring releases elastic potential energy, which can reduce the acting force required for the operation of the air cylinder, that is, the lifting force of the telescopic rod. That is, the above setting is beneficial to the lifting and lowering of the material frame.

[0011] Preferably, a buckle is arranged on the frame. A fixing bolt is inserted through the lower part of the buckle, and the fixing bolt is threadedly connected to the frame. The upper part of the buckle buckles and supports the first guide rail. The first guide rail is fixedly connected to the frame through the buckle and the fixing bolt.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The first guide rail and the second guide rail are provided. The material frame moves on the first guide rail and the second guide rail. When the material frame moves to the second guide rail, the air cylinder works and the telescopic rod extends to immerse the material frame into the passivation container for passivation treatment. After passivation, the telescopic rod retracts, and the material frame can be sent out along the first guide rail. The above can realize automatic passivation treatment and avoid direct operation by operators.

[0014] 2. Components such as a push-pull rod and a spring are provided. During the descending process of the material frame, the spring provides a buffering function. During the ascending process of the material frame, the spring provides an upward supporting force. This setting maximally avoids splashing of the passivation solvent and at the same time reduces the lifting burden of the air cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 3 As shown, a device for passivating the surface of an accessory includes a frame 2, which is a rectangular support frame composed of a plurality of square steels. A passivation container 5 is fixedly connected to the inner side of the lower part of the frame 2. The passivation container 5 is a rectangular structure and stores a passivation solvent for passivation treatment inside.

[0022] The first guide rails 3 are fixedly connected to both sides of the middle of the frame 2, an opening is provided in the middle of the first guide rail 3, and a second guide rail 6 is connected to the opening, that is, the second guide rail 6 can be staggered relative to the first guide rail 3, and a groove is provided on the opposite side of the first guide rail 3 and the second guide rail 6. The device also includes a material frame 4, and the upper end edge of the material frame 4 is slidably fitted in the slot, that is, a workpiece is placed in the material frame 4, and the material frame 4 moves along the first guide rail 3 and the second guide rail 6.

[0023] A pressing plate 10 is arranged above the passivation container 5, and connecting rods 9 are fixedly connected on both sides of the pressing plate 10. The lower end of the connecting rod 9 is fixedly connected to the second guide rail 6, that is, the pressing plate 10 is fixedly connected to the second guide rail 6 through the connecting rod 9, and the upper end of the frame 2 is fixedly connected to an upper fixed plate 11, and a pneumatic cylinder 14 is fixedly connected to the middle part of the upper end of the upper fixed plate 11, and the output end of the pneumatic cylinder 14 is fixedly connected to a telescopic rod 16, and the lower end of the telescopic rod 16 is fixedly connected to the pressing plate 10, that is, when the pneumatic cylinder 10 is working, the telescopic rod 16 is raised and lowered to realize the lifting and lowering of the second guide rail 6, and the material frame 4 attached to the second guide rail 6 also moves accordingly.

[0024] Support feet 1 are fixedly connected to the four corners at the lower end of the frame 2, and the support feet 1 are used to support the frame 2. A drainage platform 7 is inclined on one side of the passivation container 5. After the workpiece in the material frame 4 is passivated, the material frame 4 is moved to directly above the drainage platform 7 and left stationary, so that the passivation solvent falls onto the drainage platform 7.

[0025] One end of the first guide rail 3 extends above the drainage platform 7, that is, it provides support for the material frame 4 to hover on the drainage platform 7. And an inclined support rod 8 is fixedly connected to the middle of the frame 2, and the upper end of the inclined support rod 8 is fixedly connected to the extended first guide rail 3. The inclined support rod 8 is used to support the end of the first guide rail 3.

The push-pull rod 13 penetrates upward through the upper fixing plate 11, and a baffle 15 is fixedly connected to the upper end of the push-pull rod 13. A spring 12 is sleeved on the push-pull rod 13. One end of the spring 12 abuts against the upper end of the upper fixing plate 11, and the other end abuts against the baffle 15. In the above structure, when the second guide rail 6 descends, the spring 12 is compressed and stores elastic potential energy. At this time, under the action of the spring 12, the descent of the second guide rail 6 is buffered, so that the acceleration of the material frame 4 descending is reduced. When the material frame 4 is immersed in the passivation container 5, splashing of the passivation solvent is avoided. When the second guide rail 6 is lifted, the spring 12 releases elastic potential energy, promoting the lifting of the material frame 4 and reducing the operating burden of the air cylinder 14.
