Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a rust removal device for metal processing. Background Technology

[0002] Rust removal refers to the methods of removing rust from metal surfaces using various means. Rust on metal is an oxide of metal. When rust exists on the metal surface, it causes parts to adhere excessively to other parts, affecting the normal use of the metal parts. Rust removal equipment can be used to quickly and effectively remove rust from parts. Rust removal is usually required in the metal product processing process.

[0003] For example, a rust removal device for metal processing disclosed in Chinese Patent Publication No. (CN217800908U) includes a support frame, a conveyor box located on the rear side of the top of the support frame, a rust removal and grinding device located on the top of the conveyor box, a motor fixedly connected to the right side of the top of the inner wall of the support frame, the top of the motor output shaft extending through to the top of the support frame and fixedly connected to an eccentric wheel via a reducer, and a sliding sleeve slidably fitted onto the surface of the eccentric wheel. This utility model uses the motor and eccentric wheel to drive a perforated brush plate through the sliding sleeve to clean the ground metal plate. Then, an impeller and a circular sleeve inject dusty air into the interior of a filter bag through an air extraction sleeve and the perforated brush plate, allowing the filter bag to filter and collect the dust. This provides the advantage of easy dust collection and solves the problem that existing rust removal devices cannot collect the scattered rust dust during the grinding process, which easily causes rust dust to affect the surrounding environment.

[0004] However, the existing technology, as exemplified by the aforementioned patent, still suffers from poor purification of exhaust gas extracted during metal processing and rust removal. In order to solve the problem of drifting dust, the existing technology injects dusty air into the interior of the filter bag through an impeller and a circular sleeve via an air extraction sleeve and a perforated brush plate, so that the filter bag can filter and collect the dust. Although the dust is intercepted by the filter bag in this method, some harmful gases are generated during the removal of metal rust. The filter bag cannot effectively purify these gases, thus the impact on the surrounding environment still exists. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rust removal device for metal processing, which has advantages such as good exhaust gas purification effect, and solves the problem of poor purification effect of exhaust gas extracted during the rust removal process in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rust removal device for metal processing, comprising a processing table, wherein the upper surface of the processing table is provided with a rust removal mechanism for metal processing and exhaust gas treatment, and the upper surface of the processing table is provided with a conveying mechanism for clamping and conveying metal for rust removal;

[0007] The rust removal mechanism includes a rust removal cover fixed to the upper surface of the processing table. A fiber laser is fixed to the inner top wall of the rust removal cover. Collection covers are fixed to both sides of the fiber laser. Corrugated pipes are connected to the upper surfaces of the two collection covers. A vacuum cleaner is fixed to the upper surface of the rust removal cover. The suction end of the vacuum cleaner is connected to a T-connector. The top ends of the two corrugated pipes are respectively connected to the other two ends of the T-connector. A filter box is fixed to the outer side of the rust removal cover. A conveying pipe is connected between the filter box and the dust outlet end of the vacuum cleaner. A dust interception layer, an adsorption layer, and a purification layer are fixed to the inner wall of the filter box from top to bottom.

[0008] Furthermore, a controller is fixed to the outside of the rust removal cover, and material inlets for metal to enter and exit are opened on both the left and right sides of the rust removal cover.

[0009] Furthermore, the width of the collection hood is greater than the width of the fiber laser, and the lower surface of the filter box is connected to an exhaust pipe.

[0010] Furthermore, the dust interception layer is a high-density filter bag layer, the adsorption layer is an activated carbon layer, and the purification layer is an acid-base neutralization filler layer.

[0011] Furthermore, the conveying mechanism includes a conveyor belt fixed to the upper surface of the processing table. Fixed plates are vertically fixed on both the front and rear sides of the upper surface of the conveyor belt. Two electric push rods are fixed on the opposite sides of the two fixed plates. Clamping plates are fixed on the outer side of the output shaft of the electric push rods on both the front and rear sides.

[0012] Furthermore, the height of the clamping plate is greater than the height of the fixing plate, and the conveyor belt is located between the inner walls of the front and rear sides of the two feed inlets.

[0013] Furthermore, the upper surface of the processing table is provided with a mounting groove for fixing the conveyor belt.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This rust removal device for metal processing achieves efficient removal of rust from metal surfaces through the automatic irradiation of a laser and the cooperation of a collection hood. This reduces manual operation and improves the safety and convenience of the operation. At the same time, the vacuum cleaner and filter box work together to effectively collect and filter dust and harmful gases generated during the rust removal process, reducing environmental pollution. Because laser rust removal can precisely target rust without damaging the metal substrate, the use of an adsorption layer and a purification layer ensures the thoroughness of the rust removal effect. This not only speeds up the metal processing progress and improves production efficiency, but also reduces labor costs.

[0016] 2. This rust removal device for metal processing, through the cooperation of an electric push rod and a clamping plate, enables rapid clamping and release of metal workpieces, simplifies the operation process, and improves work efficiency. It can adapt to metal workpieces of different sizes and shapes, has good versatility, and can meet diverse processing needs. The stable design of the fixed plate and electric push rod ensures the stability of the metal workpiece during the conveying process and avoids processing errors caused by workpiece displacement.

A fiber laser 22 is fixed to the inner top wall of the rust removal cover 21. The power is turned on, the fiber laser 22 is started, and the laser power and irradiation time are adjusted according to the rust removal requirements. The operator starts the rust removal process through the controller, and the fiber laser 22 begins to irradiate the rust on the metal surface. The rust is removed under the action of the laser. Collection covers 23 are fixed on both sides of the fiber laser 22. The metal workpiece is placed in an appropriate position on the processing table 1, and the position of the rust removal cover 21 is adjusted so that it can cover the rust removal area of ​​the metal workpiece. Corrugated pipes are connected to the upper surfaces of both collection covers 23. 24. A vacuum cleaner 25 is fixed on the upper surface of the rust removal cover 21. During the rust removal process, the collection cover 23 collects the debris and contaminants generated by laser irradiation and transports these waste materials to the vacuum cleaner 25 through the corrugated pipe 24. The suction end of the vacuum cleaner 25 is connected to a three-way pipe 26, and the top ends of the two corrugated pipes 24 are respectively connected to the other two ends of the three-way pipe 26. A filter box 27 is fixed on the outside of the rust removal cover 21. The vacuum cleaner 25 sucks in the collected exhaust gas and dust through the three-way pipe 26 and sends it into the filter box 27 for purification. A conveying pipe 28 is connected between the filter box 27 and the dust outlet end of the vacuum cleaner 25. The inner wall of the filter box 27 is fixed with a dust interception layer 29, an adsorption layer 210 and a purification layer 211 from top to bottom.

[0024] In this embodiment, a controller is fixed to the outside of the rust removal cover 21. The left and right sides of the rust removal cover 21 are provided with material inlets for metal to enter and exit. The width of the collection cover 23 is greater than the width of the fiber laser 22. The lower surface of the filter box 27 is connected to the discharge pipe. The dust interception layer 29 is a high-density filter bag layer, the adsorption layer 210 is an activated carbon layer, and the purification layer 211 is an acid-base neutralization filler layer. The dust interception layer 29, the adsorption layer 210, and the purification layer 211 in the filter box 27 sequentially filter and purify the exhaust gas. The purified air is discharged along the discharge pipe. After the rust removal is completed, the laser and the vacuum cleaner 25 are turned off, and the metal workpiece is taken out for inspection to ensure that the rust has been completely removed.

[0025] Please see Figure 3In order to clamp and transport metal for rust removal, the conveying mechanism 3 in this embodiment includes a conveyor belt 31 fixed on the upper surface of the processing table 1. The metal workpiece to be derusted is placed on the conveyor belt 31 to ensure that the workpiece is in the correct position so that it can smoothly enter the rust removal area. The front and rear sides of the upper surface of the conveyor belt 31 are vertically fixed with fixing plates 32. Two electric push rods 33 are fixed on the opposite side of the two fixing plates 32. Clamping plates 34 are fixed on the outer side of the output shaft of the electric push rods 33 on both the front and rear sides. The clamping plates 34 are operated by the electric push rods 33 to move and clamp the metal workpiece, ensuring that the workpiece is stable during the conveying process.

[0026] In this embodiment, the height of the clamping plate 34 is greater than the height of the fixed plate 32. The conveyor belt 31 is located between the inner walls of the front and rear sides of the two material inlets. The drive motor of the conveyor belt 31 is started, and the conveyor belt 31 starts to run, conveying the metal workpiece to the rust removal area. When the metal workpiece is conveyed to the rust removal area, the rust removal mechanism 2 starts to work and performs rust removal treatment on the workpiece. The upper surface of the processing table 1 is provided with an installation groove for the conveyor belt 31 to be fixedly installed. After the rust removal is completed, the conveyor belt 31 continues to run, moving the metal workpiece out of the rust removal area. Subsequently, the electric push rod 33 operates the clamping plate 34 to release the metal workpiece.

[0027] The working principle of the above embodiments is as follows:

[0028] (1) First, ensure that the metal workpiece is placed in the appropriate position on the processing table 1 and adjust the position of the rust removal hood 21 so that it can cover the rust removal area of ​​the metal workpiece. Turn on the power, start the fiber laser 22, and adjust the laser power and irradiation time according to the rust removal requirements. The operator starts the rust removal process through the controller. The fiber laser 22 begins to irradiate the rust on the metal surface. The rust is removed under the action of the laser. During the rust removal process, the collection hood 23 collects the debris and contaminants generated by the laser irradiation and transports these wastes to the vacuum cleaner 25 through the corrugated pipe 24. The vacuum cleaner 25 sucks in the collected exhaust gas and dust through the three-way pipe 26 and sends it into the filter box 27 for purification. The dust interception layer 29, adsorption layer 210 and purification layer 211 in the filter box 27 filter and purify the exhaust gas in sequence. The purified air is discharged along the exhaust pipe. When the rust removal is completed, turn off the laser and the vacuum cleaner 25, take out the metal workpiece for inspection, and ensure that the rust has been completely removed.

[0029] (2) Place the metal workpiece that needs to be derusted onto the conveyor belt 31, ensuring that the workpiece is in the correct position so that it can smoothly enter the derusting area. Operate the clamping plate 34 by the electric push rod 33 to move and clamp the metal workpiece, ensuring that the workpiece is stable during the conveying process. Start the drive motor of the conveyor belt 31 to make the conveyor belt 31 start running and transport the metal workpiece to the derusting area. When the metal workpiece is transported to the derusting area, the derusting mechanism 2 starts to work and performs derusting treatment on the workpiece. After the derusting is completed, the conveyor belt 31 continues to run and removes the metal workpiece from the derusting area. Then, the electric push rod 33 operates the clamping plate 34 to release the metal workpiece.
