Description

Technical Field

[0001] This utility model relates to the technical field of metal surface treatment equipment, specifically to a surface treatment device for circular forgings. Background Technology

[0002] Round forgings are prone to oxide scale and rust formation after being stored in the open air, requiring surface treatment before further processing. Currently, rust removal mainly relies on manual labor using tools such as angle grinders and wire wheels, which suffers from low efficiency, high labor intensity, poor safety, and inconsistent treatment quality. Existing automated equipment, such as through-feed shot blasting machines, also has blind spots when processing round parts and is difficult to adapt to workpieces of different diameters, resulting in relatively limited functionality.

[0003] Therefore, there is a need in the field for a specialized device that can automatically, uniformly, and efficiently complete rust removal and subsequent treatment of the surface of circular forgings. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surface treatment device for circular forgings that has a reasonable structure, a high degree of automation, and uniform processing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for circular forgings, comprising a base, a bed, and a workpiece, wherein the bed is slidably mounted on the base, characterized in that it further comprises: An enclosed cabin is installed on the bed. A clamping and rotating system, mounted on the bed, is used to clamp and drive a circular forging to rotate around its own axis. The clamping and rotating system includes a headstock and a tailstock, on which ejector pins are arranged opposite each other. The headstock is provided with a first drive mechanism for driving the ejector pins thereon to rotate. The tailstock is slidably mounted on a linear guide rail and is driven by a second drive mechanism to move closer to or away from the headstock. At least one surface treatment unit is disposed within the enclosed chamber for performing operations on the surface of a rotating workpiece. An adaptive feed mechanism is provided, connected to the surface treatment unit, for pressing the surface treatment unit onto the workpiece surface; the adaptive feed mechanism includes a floating support and a pressure control assembly, the floating support enabling the surface treatment unit to float radially relative to the workpiece surface, and the pressure control assembly providing a constant propulsion force to the floating support.

[0006] Furthermore, the surface treatment unit includes a rust removal station and a cleaning and drying station arranged sequentially along the workpiece axis.

[0007] Furthermore, the rust removal station is a belt abrasive head or a rotary wire brush.

[0008] Furthermore, the cleaning and drying station includes a high-pressure spray device and a hot air drying device.

[0009] Furthermore, the pressure control component is a pneumatic servo cylinder or a hydraulic servo cylinder.

[0010] Furthermore, the surface treatment unit is also equipped with an axial moving mechanism, which is used to drive the surface treatment unit to reciprocate along the workpiece axis.

[0011] Furthermore, it also includes a dust removal system and a drainage system, which are installed inside the enclosed cabin.

[0012] Furthermore, it also includes a central control system, which is electrically connected to the clamping and rotating system, the surface treatment unit, and the adaptive feed mechanism.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention has the following advantages: By driving the workpiece to rotate through a clamping and rotating system, and combining this with the operation of the surface treatment unit, the circumferential surface of the circular forging is treated without any dead angles, effectively solving the problem of processing uniformity.

[0014] By setting an adaptive feed mechanism, it can automatically adapt to workpieces of different diameters and maintain a constant processing pressure, thus solving the problem of unstable processing quality caused by changes in workpiece size.

[0015] By integrating multiple workstations such as rust removal, cleaning, and drying, the surface treatment process is integrated into a single operation, solving the problem of low efficiency caused by requiring multiple machines and multiple turnovers.

[0016] By setting up a closed cabin, dust removal system and drainage system, the dust and wastewater generated during the treatment process are effectively collected, solving the problems of harsh working environment and environmental protection. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and specific examples. These examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] like Figures 1 to 4 As shown, the present invention provides a surface treatment device for circular forgings. Its basic structure includes a robust base 1, typically welded from structural steel, providing stable support for the entire device. A bed 16 is slidably mounted on the base 1 via a slider mechanism, allowing the entire processing unit to be easily moved out of the enclosed chamber 2 when maintenance or adjustment is required. The sliding of the bed 16 can be driven electrically or hydraulically. The enclosed chamber 2 is fixedly mounted on the bed 16, typically made of steel plate, and equipped with an observation window and a sealed door to form a closed working space.

[0024] The clamping and rotating system is one of the core components of this invention. The headstock 4 is fixedly mounted on the bed 16, and the tailstock 5 is slidably mounted on the linear guide rail 8 via a slider, ensuring a relatively fixed positional relationship with the bed 16. The headstock 4 integrates a first drive mechanism 7, which preferably uses a servo motor in conjunction with a planetary reducer to provide stable and precisely controllable rotational power. A pin 6 is mounted at the output end of the first drive mechanism 7 for inserting into the center hole at one end of the workpiece 3. Correspondingly, a freely rotatable pin 6 is also mounted on the tailstock 5. The tailstock 5 is slidably mounted on the linear guide rail 8 via a slider, and the linear guide rail 8 is fixedly mounted on the bed 16. A second drive mechanism 9 drives the tailstock 5 to move, preferably using a servo motor to drive a ball screw, converting the rotational motion into linear motion of the tailstock 5 through a screw-nut pair, thereby achieving workpiece clamping and release. During clamping, the pins 6 on the headstock 4 and tailstock 5 together insert into the center holes at both ends of the workpiece 3, forming a stable three-point support.

[0025] The surface treatment unit 15 is installed inside the enclosed chamber 2 via an adaptive feeding mechanism 12. For example... Figure 3 , 4As shown, the adaptive feed mechanism 12 includes a floating support 121, which is slidably mounted on the bed 16 via a linear guide mechanism, allowing it to move radially along the workpiece 3. A pressure control assembly 122 is connected to the floating support 121, providing it with a propulsive force toward the workpiece 3. The pressure control assembly 122 preferably employs a pneumatic servo cylinder. Through feedback signals from a pressure sensor, the central control system dynamically adjusts an electro-proportional valve to maintain a preset pressure, precisely controlling the output force to maintain a constant contact pressure. When the workpiece 3 has diameter deviations or out-of-roundness, the floating support 121 can automatically compensate for displacement changes under the push of the pressure control assembly 122, always maintaining the preset processing pressure.

[0026] In a preferred embodiment, multiple surface treatment units 15 are arranged sequentially along the axial direction of the workpiece 3. The rust removal station 10 serves as the primary treatment station, and its execution end can employ a high-speed rotating wire brush for powerful removal of thick rust and oxide scale; alternatively, it can use a belt abrasive head, suitable for applications requiring higher surface finish. The subsequent cleaning and drying station 11 integrates a high-pressure spray device and a hot air drying device. The high-pressure spray device atomizes water or environmentally friendly cleaning fluid using a water pump and nozzles, spraying it onto the workpiece surface to wash away residual shavings and impurities; the hot air drying device rapidly dries the workpiece surface using a high-speed hot airflow generated by an electric heater and a high-pressure blower, preventing secondary rusting.

[0027] To ensure that the entire axial surface of workpiece 3 is uniformly treated, each surface treatment unit 15 is also equipped with an axial movement mechanism (not shown in the figure). This mechanism can be a ball screw system driven by a stepper motor, which drives the entire surface treatment unit 15 to reciprocate along the axial direction of workpiece 3 to ensure uniform treatment of the entire axial surface. The movement speed can be adjusted according to process requirements.

[0028] In terms of environmental protection, the enclosed chamber 2 is equipped with a dust removal system 17 and a drainage system 18. The dust removal system 17 typically includes a suction port, pipes, and a cartridge dust collector for continuously removing dust generated during the processing. The drainage system 18 includes a water collection tank at the bottom of the chamber, drainage pipes, and a sedimentation and filtration device to collect and recycle cleaning wastewater.

[0029] This utility model is also equipped with a central control system (not shown in the figure), which typically uses a programmable logic controller (PLC) as the control core, along with a human-machine interface (HMI). The central control system is electrically connected to the first drive mechanism 7, the second drive mechanism 9, the actuators of each surface treatment unit 15, the pressure control component 122, and the axial movement mechanism. Operators can set workpiece parameters and process parameters through the HMI, and the system can automatically complete the entire processing flow, achieving intelligent control.

[0030] The workflow of this utility model is as follows: Loading: Open the sealed door of the enclosed cabin 2, use an overhead crane to hoist the workpiece 3 to be processed into it, and temporarily place it on the support seat inside the cabin.

[0031] Clamping and centering: The operator initiates the clamping procedure through the central control system. The second drive mechanism 9 drives the tailstock 5 to move towards the headstock 4 until the ejector pins 6 at both ends are reliably inserted into the center hole of the workpiece 3, and stops after reaching the preset clamping force.

[0032] Start-up process: The first drive mechanism 7 is activated, driving the workpiece 3 to rotate at a set speed. Subsequently, each surface treatment unit 15 is activated according to a preset program. The rust removal station 10 is pressed against the workpiece surface under the action of the adaptive feed mechanism 12, and can simultaneously reciprocate along the axial direction to perform a comprehensive rust removal operation.

[0033] Cleaning and Drying: The rust-removed workpiece 3 continues to rotate and enters the cleaning and drying station 11. First, the high-pressure spray device is started to rinse the surface of the workpiece; then the hot air drying device is started to quickly dry the surface.

[0034] Completion and Unloading: After all processing steps are completed, each processing unit returns to its original position, the workpiece stops rotating, the tailstock 5 retracts, and the ejector pin releases the workpiece. The operator can then use an overhead crane to lift the processed workpiece out, completing the entire work cycle.

[0035] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model; therefore, all equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by the claims.
