Technical Field

[0001] The utility model belongs to the technical field of metal surface treatment, in particular to a metal surface treatment device for anodized films. Background Art

[0002] Metal parts are common objects in daily life, usually made of iron. Since iron is not corrosion-resistant, in order to ensure the durability of metal parts, it is sometimes necessary to coat a layer of anodized film on their surface. This operation can provide metal parts with good corrosion resistance and wear resistance. This operation requires the use of special metal surface treatment equipment. In order to ensure that the oxide film can be evenly generated on the surface of the metal parts, the equipment needs to be improved.

[0003] Although the existing device can make the oxide film on the surface of the metal part more uniform, the metal part used for electroplating is not convenient to disassemble and assemble.

[0004] For example, a metal anodizing treatment device with a Chinese utility model application number of CN201920420164.8 includes an oxidation tank, a metal part and a cathode rod, a DC power supply is installed on one side wall of the oxidation tank, and a fixing frame is installed on the other side wall of the oxidation tank by bolts, a heating bottom plate is arranged at the bottom end of the oxidation tank, and a stirring fan is fixedly installed between the inner walls of the oxidation tank by a fixing plate, and a temperature sensor is embedded on one side of the inner wall of the oxidation tank, and a cathode rod is connected to one side of the bottom of the fixing frame by a conductive column. The device is used for electroplating metal parts that are not convenient to disassemble and assemble. Utility Model Content

[0005] The utility model aims to provide a metal surface treatment device for anodized film to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a metal surface treatment device for anodized film, comprising:

[0007] An oxidation tank and a metal surface treatment assembly mounted on top of the oxidation tank;

[0008] The metal surface treatment component includes an L-shaped mounting frame installed on one side of the top of the oxidation tank, a cathode rod is installed at the bottom center of the mounting frame, a linear reciprocating motor is installed on one side of the top of the mounting frame, and the output end of the linear reciprocating motor passes through the top of the mounting frame and is connected to a connecting column, a metal part is provided at the bottom of the connecting column, an iron core and a conductive rod are connected side by side on the inner side of the connecting column, and the bottom of the conductive rod passes through the connecting column and abuts against the top of the metal part, a solenoid is wound around the side wall of the iron core, and the top of the oxidation tank is constructed with openings corresponding to the cathode rod and the metal part.

[0009] In a further embodiment, a motor is installed at the bottom center of the oxidation tank, and the output end of the motor passes through the bottom of the oxidation tank and is coaxially connected to a rotating shaft, and the side walls of the rotating shaft are evenly connected with multiple stirring blades, and heat conduction plates are nested and installed on the symmetrical inner walls on both sides of the oxidation tank.

[0010] In a further embodiment, an electric heater is installed on one outer wall of the oxidation tank, and a heat conducting wire is connected between the electric heater and the heat conducting plate.

[0011] In a further embodiment, moving wheels with braking function are installed at the four corners of the bottom of the oxidation tank.

[0012] In a further embodiment, a reinforcement seat is fixedly sleeved on the side wall of the linear reciprocating motor, and the reinforcement seat is connected to the top of the mounting frame by a plurality of bolts.

[0015] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0016] The existing solution of the metal surface treatment device of the anodized film can improve the uniformity of the surface oxidation of the metal part by driving the metal part to repeatedly enter and exit the oxidation tank, but the metal part needs to be fixed by multiple structures, or fixed by plug-in or socket-in, but the stability is not high enough and it is easy to fall off accidentally. The present solution uses an electromagnet composed of an iron core and a solenoid to adsorb and fix the iron metal part. When it needs to be removed, it only needs to be powered off, and the metal part used for electroplating can be easily disassembled and assembled;

[0017] The electrolyte is heated simultaneously by the heat conducting plates on both sides, and the bottom is accelerated by the continuous rotation of multiple stirring blades to accelerate the heating process. Compared with the bottom heating method, the heating efficiency is higher, thereby accelerating the oxidation process and increasing the speed of oxide film formation;

[0018] The metal surface treatment device of the anodized film is convenient for disassembly and assembly of electroplated metal parts. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0029] In order to facilitate the disassembly and assembly of the metal parts 6 used for electroplating, Figures 1 to 4 As shown, it includes: an oxidation tank 1 and a metal surface treatment component installed on the top of the oxidation tank 1, the metal surface treatment component includes an L-shaped mounting frame 2 installed on one side of the top of the oxidation tank 1 through multiple sets of bolts, a cathode rod 3 is installed at the bottom center of the mounting frame 2, a conductive column is fixedly inserted on the top of the cathode rod 3, and the conductive column is used to provide power to the cathode rod 3 using the existing principle, and the conductive column is welded to the bottom of the mounting frame 2.

[0030] A linear reciprocating motor 4 is installed on one side of the top of the mounting frame 2. A reinforcement seat 10 is fixedly sleeved on the side wall of the linear reciprocating motor 4, and the reinforcement seat 10 is connected to the top of the mounting frame 2 by multiple bolts, which increases the working stability of the linear reciprocating motor 4 and ensures that the metal part 6 can be lifted and lowered smoothly. The output end of the linear reciprocating motor 4 passes through the top of the mounting frame 2 and is connected to a connecting column 5 by bolts. A metal part 6 is arranged at the bottom of the connecting column 5. The linear reciprocating motor 4 drives the lifting interface of the connecting column 5 to control the lifting of the metal part 6.

[0031] The inner side of the connecting column 5 is connected with an iron core 7 and a conductive rod 9 in parallel by threads. The threaded connection is convenient for disassembly and assembly, and the bottom of the conductive rod 9 passes through the connecting column 5 and contacts the top of the metal part 6, ensuring that the conductive rod 9 can provide power to the metal part 6 using the existing principle. The side wall of the iron core 7 is wound with a solenoid 8. The iron core 7 and the solenoid 8 on its side wall constitute an electromagnet. When the solenoid 8 is energized, magnetic force can be generated, which can adsorb and fix the iron metal part 6 below. The top of the oxidation tank 1 is constructed with openings corresponding to the cathode rod 3 and the metal part 6, which facilitates the cathode rod 3 and the metal part 6 to enter and exit the oxidation tank 1.

[0032] Moving wheels 16 with braking function are installed at the four corners of the bottom of the oxidation tank 1 to facilitate the movement of the device. A sign 15 is adhered to the outer wall of one side of the oxidation tank 1. The surface of the sign 15 is marked with operating specifications to facilitate the staff to understand.

[0033] Heat conducting plates 13 are nested and installed on the symmetrical inner walls of the oxidation tank 1 on both sides. The heat conducting plates 13 arranged on both sides can efficiently heat the electrolyte. After the electrolyte is heated, the oxidation process can be accelerated to increase the speed of oxide film formation. An electric heater 14 is installed on the outer wall of one side of the oxidation tank 1 through a mounting seat. The electric heater 14 can generate heat using existing principles, and a heat conducting wire (not shown in the figure) is connected between the electric heater 14 and the heat conducting plate 13, and heat can be transferred to the surfaces of the two heat conducting plates 13 through the heat conducting wire.

[0034] A motor 11 is installed at the bottom center of the oxidation tank 1 through a motor seat, and the output end of the motor 11 passes through the bottom of the oxidation tank 1 and is coaxially connected to a rotating shaft. The motor 11 drives the rotating shaft to rotate, thereby driving multiple stirring blades 12 to rotate continuously to stir the electrolyte to accelerate the heating process. The side wall of the rotating shaft is evenly connected to multiple stirring blades 12 through multiple screws.

[0035] The linear reciprocating motor 4, the motor 11, and the electric heater 14 are all set as conventional instruments. The working principle, size and model are irrelevant to the function of this application, so they are not described in detail, and they are all controlled by a remote control switch.

[0036] How it works

[0037] The metal surface treatment device of the anodized film is moved to a designated position and connected to an external power source, and the solenoid 8 is energized, so that the electromagnet composed of the solenoid 8 and the iron core 7 can generate magnetic force. At this time, the iron metal part 6 is moved to the bottom of the connecting column 5 to be fixed, and then the conductive rod 9 and the conductive column are energized respectively, and the metal part 6 is driven to rise and fall repeatedly by the linear reciprocating motor 4 to perform electroplating according to the existing principle;

[0038] While the metal part 6 is being electroplated, the electric heater 14 and the motor 11 are started. The electric heater 14 can generate heat using existing principles. The heat can be transferred to the surfaces of the two heat conducting plates 13 through the heat conducting wires to efficiently heat the electrolyte. The motor 11 drives the rotating shaft to rotate, thereby driving the multiple stirring blades 12 to rotate continuously to stir the electrolyte to accelerate the heating process. After the electrolyte is heated, the oxidation process can be accelerated to increase the speed of oxide film formation.
