Description

Technical Field

[0001] This utility model belongs to the technical field of metal processing equipment, and in particular to a phosphating equipment for metal processing. Background Technology

[0002] Phosphating equipment is mainly used for metal surface treatment, forming a protective film to improve the corrosion resistance and adhesion of the material. Existing phosphating equipment can only process a single quantity of metal material at a time, resulting in low efficiency for large-volume processing. Therefore, there is an urgent need for phosphating equipment specifically designed for metal processing.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221645061U) concerning a phosphating device for metal processing. The device includes a sprayer with a hollow housing. The top of the housing has a storage chamber for storing phosphoric acid. Below the storage chamber is a spraying chamber for phosphoric acid treatment of metal workpieces. Below the storage chamber is a collection chamber for collecting excess phosphoric acid. The spraying chamber contains a fixing assembly for fixing and rotating the metal workpieces. This device solves the problem of existing equipment being unable to flip the phosphated metal material. However, it still suffers from the limitation of only being able to phosphate a single quantity of metal workpieces per operation, reducing the device's processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a phosphating device for metal processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a phosphating device for metal processing, comprising a protective housing, an inner wall of which is connected to a shelf, the bottom of which is provided with several equally spaced arc-shaped limiting grooves, the limiting grooves penetrating the bottom wall of the shelf, and each limiting groove having a corresponding connecting hole at its end, the connecting hole being connected to an auxiliary frame for auxiliary fixing of a circular metal workpiece, the bottom of the auxiliary frame abutting against the bottom wall of the shelf, and four smooth-surfaced insert rods welded to the bottom of the shelf, the side walls of which are slidably connected to insertion holes, the insertion holes being located on the inner bottom wall of the housing, and the housing having an inclined guide groove between the four insertion holes, the guide groove extending to the outer side of the housing.

[0006] As a preferred embodiment, a collection box is provided on the outside of the feed chute, and the top of the collection box is welded to the bottom of the box body.

[0007] As a preferred embodiment, one side of the collection box is connected to a water tank, the inside of which stores phosphating liquid for metal processing.

[0008] As a preferred embodiment, an ultrasonic transducer is fixed to the bottom of the water tank.

[0009] As a preferred embodiment, a centrifugal pump is also installed inside the water tank. The output end of the centrifugal pump is connected to a flexible connecting pipe, and the other end of the connecting pipe is connected to an electric heating device. The bottom of the electric heating device is fixed to the bottom of the cover plate.

[0010] As a preferred embodiment, a surrounding plate of the same size as the shelf is welded to the bottom of the cover plate, and several evenly distributed atomizing nozzles are provided in the middle of the surrounding plate.

[0011] As a preferred embodiment, the nozzle is connected to the water channel inside the electric heating device via a connecting pipe.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This metal processing phosphating equipment, through the connection of a collection box, a water tank, a connecting pipe, and an atomizing nozzle, and with the assistance of a centrifugal pump, allows the phosphating liquid to be fully diffused inside the box, ensuring that the processed round metal workpieces are in full contact with the phosphating liquid. The aforementioned reflux structure also reduces material loss and improves the practicality of the equipment.

[0014] This metal processing phosphating equipment features an internal electric heating device with a spiral heat-conducting pipe and multiple heating tubes / plates to improve the overall heat exchange efficiency of the device. An internal heat medium ensures more uniform heating of the phosphating solution. Combined with a temperature sensor, this reduces reaction energy consumption and accelerates the reaction when the phosphating solution comes into contact with the metal, thus improving the device's processing efficiency.

[0015] This metal processing phosphating equipment features an ultrasonic transducer fixed to the bottom of the water tank. The transducer prevents the phosphating solution inside the tank from settling and automatically adjusts the vibration frequency according to parameters to avoid solid sedimentation. Combined with multiple limiting grooves set in the middle of the placement plate, it enables simultaneous processing of multiple materials when processing round metal workpieces, further improving the processing efficiency of the device.

[0016] This device solves the problem that existing equipment cannot process multiple metal workpieces simultaneously, thus improving the device's processing efficiency. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] A phosphating device for metal processing, such as Figures 1 to 5 As shown,

[0029] include:

[0030] The protective enclosure 1 is made of non-metallic or corrosion-resistant materials, such as plastic or rubber, to prevent corrosion of the equipment when phosphating round metal workpieces, since the phosphating solution is acidic. The internal structure of the enclosure is also made of the above materials.

[0031] A shelf 6 is slidably connected to the inner wall of the box 1. The bottom of the shelf 6 is provided with several equally spaced arc-shaped limiting grooves 7. The limiting grooves 7 penetrate the bottom wall of the shelf 6. The through structure can drain the phosphating solution inside the shelf 6. In order to avoid phosphating solution residue, a guide groove and a corresponding inclined structure are provided on the inner bottom wall of the shelf 6 to further accelerate the drainage speed of the phosphating solution and facilitate use.

[0032] Each limiting groove 7 is also provided with a corresponding connecting hole at its end. The connecting hole is connected to an auxiliary frame 8 for auxiliary fixing of a circular metal workpiece. The bottom of the auxiliary frame 8 abuts against the bottom wall of the placement plate 6. The limiting groove 7 can restrict the circular metal workpiece. With the auxiliary frame 8 set at both ends of the limiting groove 7, the auxiliary frame 8 is fixed by connecting the bottom connecting rod to the connecting hole, thereby assisting the limiting groove 7 in limiting the metal workpiece. In order to ensure the phosphating effect of the metal workpiece is complete, the limiting grooves of the limiting groove 7 and the auxiliary frame 8 are both larger than the thickness of the workpiece.

[0033] Four smooth-surfaced insert rods are welded to the bottom of the shelf 6. Insert holes 10 are slidably connected to the side walls of the insert rods. The insert holes 10 are located on the inner bottom wall of the connecting groove 9. The connecting groove 9 is located inside the box 1 and is detachably connected. The connecting groove 9 has an inclined guide groove 11 in the middle of the four insert holes 10. By fixing the shelf 6 to the inner bottom wall of the box 1, the phosphating liquid can be concentrated to the bottom of the box 1 under the action of the limiting groove 7. With the help of the guide groove 11, the phosphating liquid inside the box 1 can be discharged. In order to avoid some liquid remaining on the surface of the shelf 6 when phosphating the workpiece, a guide plate can be welded to the inner wall of the box 1. The guide plate can shield the frame of the side wall of the shelf 6 to further reduce material loss, but the guide plate should not affect the processing of the workpiece.

[0034] The feed chute 11 extends to the outside of the box 1 and connects to the connection port 14 provided on the top of the collection box 2. The top of the collection box 2 is welded to the bottom of the box 1, and then the excess phosphating liquid is collected under the action of the feed chute 11 and the connection port 14.

[0035] A water tank 15 is also fixed to the side wall of the collection box 2. The side wall of the water tank 15 is welded to the side wall of the box body 1. With the help of a centrifugal pump installed inside the water tank 15, the phosphating solution inside the whole device is circulated. Under the action of the flexible connecting pipe 4 made of flexible material, the phosphating solution is pumped to the inside of the electric heating device 5. With the help of the temperature sensor installed at the output end of the electric heating device 5, the temperature of the output phosphating solution is controlled. According to the metal workpieces that need to be processed, the temperature is controlled, which can not only accelerate the processing efficiency and phosphating quality of the workpieces, but also prevent precipitation and improve the permeability of the phosphating film to adapt to different materials and improve the adaptability of the device.

[0036] The bottom of the electric heating device 5 is connected to the top of the cover plate 3 by screws. Through the U-shaped and multi-layer heating tube / plate structure set inside the electric heating device 5, the medium inside the electric heating device 5 is fully heated. Then, under the action of the medium, the phosphating solution that runs through the water channel inside the electric heating device 5 is heated. With the help of the set temperature sensor, the air volume of the phosphating solution is controlled, which makes it convenient to phosphating workpieces of different metal materials.

[0037] A U-shaped enclosure 12 is welded to the bottom of the cover plate 3. The size of the enclosure 12 is the same as that of the shelf 6, which can further reduce the splashing of the sprayed phosphating liquid on the top of the shelf 6. Several evenly arranged atomizing nozzles 13 are provided in the middle of the enclosure 12. The nozzles 13 can atomize the heated phosphating liquid under the action of a centrifugal pump, thereby performing phosphating treatment on the workpiece fixed by the limiting groove 7 and the auxiliary frame 8, which is convenient for use.

[0038] One end of the cover plate 3 is hinged to the box body 1, and the other side is connected to the locking block through a set insert block. The side wall of the locking block is fixed to the side wall of the box body 1. Thus, the storage plate 6 can be separated from the box body 1 by opening and closing the cover plate 3, which facilitates the retrieval of materials after workpiece processing and makes operation convenient.

[0039] The electric heating device 5, centrifugal pump, ultrasonic transducer, and temperature sensor are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0040] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0041] Working principle

[0042] When using this metal processing phosphating equipment, the mixed phosphating solution is injected into the water tank 15 through the filling port. Under the action of the centrifugal pump, the liquid is transported to the water channel inside the electric heating device 5 in conjunction with the connecting pipe 4.

[0043] The electric heating device 5 is started and the temperature is adjusted according to the different metal materials being processed under the action of the temperature sensor. Then, the phosphating solution is atomized and sprayed out through the nozzle 13 set at the bottom of the cover plate 3, thereby processing the metal workpiece fixed inside the placement plate 6.

[0044] Finally, the phosphating solution is collected by the limiting groove 7 and the guiding groove 11, and the liquid inside the collection box 2 is recycled to the water tank 15 through the connecting structure.
