Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wire processing, and particularly relates to a surface rust removal machine for wire processing. BACKGROUND

[0002] In the processing, storage and use of metal wires (such as steel wires, copper bars, etc.), the surface will inevitably be oxidized and corroded due to contact with air and moisture. The existence of corrosion will seriously affect the quality and yield of the subsequent processes (such as drawing, plating, calendering, etc.) of the wires. Therefore, surface rust removal treatment of the wires before further processing is a crucial process.

[0003] The traditional wire rust removal methods mainly have the following problems and deficiencies: 1. Chemical pickling method: the principle is to immerse the wire into acid solution (such as hydrochloric acid, sulfuric acid), and dissolve the surface rust by chemical reaction.

[0004] The disadvantages are: 1. Serious environmental pollution: a large amount of acid mist, waste acid and wastewater will be generated, which has high treatment cost and does not meet the requirements of green manufacturing.

[0005] 2. Harm to human health: acid mist has serious harm to the respiratory system and skin of the operators.

[0006] 3. Easy to produce hydrogen embrittlement: hydrogen atoms will penetrate into the metal during the pickling process, which will reduce the toughness and plasticity of the wire and affect its mechanical properties.

[0007] 4. Complex process control: the concentration, temperature and soaking time of the acid solution need to be strictly controlled.

[0008] 2. Mechanical rust removal method: the principle is to use fixed grinding blocks or rotating grinding wheels to grind the moving wire in one direction or limited angle.

[0009] The disadvantages are: 1. Existence of grinding dead angle: it is difficult to uniformly treat the entire circumferential surface of the wire, especially for wires with pits or complex shapes.

[0010] 2. Inconvenient adjustment: when replacing wires of different diameters, it is very tedious to adjust the grinding mechanism, and the downtime is long.

[0011] 3. Difficult maintenance: the transmission structure is complex or closed, and the internal wear parts are not convenient to replace and maintain.

[0012] In summary, the existing technology urgently needs a wire rust removal scheme that can overcome the above-mentioned shortcomings, i.e. a physical rust removal equipment that is efficient, environmentally friendly, non-destructive to the substrate, easy to adjust and maintain. SUMMARY

[0013] The purpose of this invention is to provide a surface rust removal machine for wire processing. Through the design of the grinding unit, transmission unit and drive mechanism, it can realize the revolution and rotation of the grinding wheel, and the combined grinding mode of revolution sweeping and rotation cutting. This makes the contact trajectory between the grinding wheel and the wire very complex and dense, which is equivalent to performing countless cross grindings on the surface of the wire in a very short time. This completely eliminates the grinding dead angles that exist in traditional methods and achieves efficient, uniform and all-round rust removal effect and uniformity.

[0014] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a surface rust removal machine for wire processing, comprising a frame, a grinding unit, a transmission unit, and a drive mechanism; The frame consists of a lower frame and an upper frame with a box-type structure, and external guide molds are fixed through both sides of the upper frame; The grinding unit includes two turntables and a hollow wire threading shaft. The wire threading shaft is installed in the upper frame through an upper bearing seat and is concentric with the outer wire guide mold. Inner wire guide molds are fixed at both ends of the wire threading shaft. The two turntables are installed at both ends of the threading shaft. A grinding shaft is rotatably connected to one opposite side of each turntable, and a first gear is rotatably connected to the other opposite side of each turntable. A grinding wheel is fixed to the outer end of each grinding shaft, and a grinding interval is formed between the two grinding wheels, which is opposite to the inner wire mold. The inner end of the grinding shaft is fixed with a second gear. The two first gears are located inside the turntable and are connected to the two second gears through a toothed belt. The turntable is provided with four tension wheels, which are spaced between the two first gears and the two second gears. The main pulley is fixed in the middle of the threading shaft, and both ends of the threading shaft are rotatably connected to the upper pulley assembly through bearings. The transmission unit includes a transmission shaft parallel to the threading shaft. The transmission shaft is installed in the lower frame through a lower bearing seat. A lower pulley group is fixed in the middle of the transmission shaft and side pulleys are fixed at both ends. Both the lower and upper pulley sets are composed of a large pulley and a small pulley connected coaxially. An input pulley is coaxially connected to one of the first gears on the turntable. The input pulley is connected to the small pulley of the upper pulley set via a belt. The drive mechanism is a motor installed at the bottom of the lower frame. The output end of the drive mechanism is fixed with an output pulley. The output pulley is connected to the large pulley of the lower pulley group via a belt. The small pulley of the lower pulley group is connected to the main pulley via a belt. The side pulley is connected to the large pulley of the upper pulley group via a belt.

[0015] Furthermore, both the upper and lower frames are box-type frames. The lower frame has an inspection door on its outer side, and the top two sides of the upper frame are connected by hinges to side flaps. A first air spring is installed between the side flaps and the upper frame.

[0016] Furthermore, the main flip cover is connected to the front and rear sides of the top of the upper frame by hinges. The main flip cover is located in the area between the hinges of the two side flip covers. A second air spring is provided between the main flip cover and the upper frame.

[0017] Furthermore, the turntable has a straight groove for mounting the grinding shaft and the tension wheel. Both the grinding shaft and the tension wheel have a support plate that can slide along the turntable. An adjustment mechanism is provided between the end of the support plate and the turntable. The adjustment mechanism of the grinding shaft is used to adjust the grinding interval between the two grinding wheels, and the adjustment mechanism of the tension wheel is used to adjust the tension of the toothed belt.

[0018] Furthermore, a pad is provided at the outer edge of the turntable, which is opposite to the straight groove, and an end plate parallel to the pad is fixed at the end of the support plate. The adjustment mechanism is a bolt structure and is installed between the pad and the end plate.

[0019] Furthermore, it also includes a negative pressure adsorption mechanism, which is installed on the front side inside the lower frame. The negative pressure adsorption mechanism includes a manifold box, on the top of which are two adsorption heads facing the grinding intervals at both ends of the grinding unit, and on the bottom of which is a fan.

[0020] Furthermore, both ends of the threading shaft are provided with flanges, and the turntable is installed at the end of the threading shaft through the flanges. The turntable has a shaft opening at its center that is opposite to the inner wire mold, and a mold cover fixed to the end of the threading shaft is provided inside the shaft opening.

[0021] Furthermore, the grinding shaft is provided with a reinforcing groove parallel to the straight groove around its corresponding straight groove, and the grinding shaft is provided with screws that slide along the reinforcing groove.

[0022] Furthermore, three-point wheel guide frames are fixed on both sides of the upper frame, and the material threading line of the three-point wheel guide frame is concentric with the outer guide mold.

[0023] Furthermore, the main pulley, upper pulley group, side pulley, lower pulley group, input pulley, and output pulley are all multi-groove pulleys, and the belt is an A-type belt or a B-type belt.

[0024] The present invention has the following beneficial effects: 1. This invention, through the design of the grinding unit, transmission unit, and drive mechanism, enables the combined grinding method of the grinding wheel's revolution and rotation, revolution sweeping, and rotation cutting. This results in a very complex and dense contact trajectory between the grinding wheel and the wire, which is equivalent to performing countless cross-grinding operations on the wire surface in a very short time. This completely eliminates the grinding dead angles present in traditional methods and achieves a highly efficient, uniform, and all-around rust removal effect.

[0025] 2. This invention, through the straight groove and adjustment mechanism on the turntable, can precisely adjust the distance between the two grinding wheels, enabling a single device to easily adapt to wires of different diameters. It is highly versatile, and switching product specifications is very convenient, achieving a high degree of adaptability and flexible adjustability.

[0026] 3. This invention, through the design of adjustable tension pulleys, ensures that the transmission system maintains stable and reliable power transmission under different working conditions and different wire specifications, prevents slippage or tooth skipping, and extends the service life of belts and gears. At the same time, the design of four tension pulleys enables the optimal belt wrap angle and transmission efficiency. Similarly, the multi-point adjustment establishes stable and uniform tension control.

[0027] 4. This invention constructs a multi-stage wire guide system through the design of a three-point wheel guide frame, an outer guide mold, and an inner guide mold. This ensures that the wire is always aligned with the center of the grinding wheel, preventing the wire from deviating or vibrating, thereby guaranteeing the uniformity of rust removal and the straightness of the wire, and improving the rust removal effect and quality.

[0028] 5. By employing a side-flip cover and a main-flip cover on the upper frame and equipping it with an air spring, the entire working area can be easily and quickly opened, making it extremely convenient to replace worn grinding wheels, inner guide molds, adjust mechanisms, or perform routine maintenance, greatly reducing equipment downtime.

[0029] 6. This invention integrates a negative pressure adsorption mechanism and directly sets an adsorption head at the grinding interval, which can capture and collect dust and debris generated during grinding from the source. This greatly improves the working environment, protects workers' health, meets the environmental protection requirements of modern industry, and the collected waste is also easy to centrally process.

[0030] 7. This invention constructs a stable and reliable transmission system that uses only one motor to simultaneously drive the rotation of the threading shaft and the rotation of the grinding wheel. The transmission route is clear and the structure is compact. At the same time, the multi-groove belt drive has the functions of buffering, vibration absorption, and overload protection, and the operation is smooth with low noise.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
