Description

Technical Field

[0001] This utility model is a stainless steel workpiece powder recovery device, belonging to the field of metal processing technology. Background Technology

[0002] 434 stainless steel is made by adding molybdenum to 430 steel. This addition improves the steel's resistance to pitting corrosion, crevice corrosion, and overall strength. It is known for its good corrosion resistance, toughness, and weldability, and performs particularly well in resistance to chloride stress corrosion compared to other types of stainless steel. During the processing of stainless steel, various machines cut the stainless steel material, resulting in a large amount of 434 stainless steel powder falling off. This powder is easily scattered by the cutting machine, necessitating filtration and recycling.

[0003] Publication number CN211160548U mentions a metal powder recovery device for stainless steel processing. The device uses an internal suction fan to attract the metal powder, effectively collecting and recovering the scattered metal powder during stainless steel processing, thus improving the recovery efficiency. A fine screen is installed on the surface of the device to filter out solid impurities from the metal powder, effectively improving the purity of the recovered metal powder. However, the fixed position of the fine screen and the unreasonable structural design make it prone to metal powder blockage or accumulation, resulting in slow processing speed and affecting overall work efficiency. There is an urgent need for a stainless steel workpiece powder recovery device to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a stainless steel workpiece powder recovery device to solve the problems mentioned in the background. This invention employs a reciprocating piston and filter structure, which can drive the fine screen to vibrate continuously, thereby preventing the 434 stainless steel metal powder falling on the fine screen from clogging or accumulating. Combined with the adsorption effect of the suction fan, the subsequent stainless steel workpiece powder recovery efficiency can be guaranteed.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stainless steel workpiece powder recovery device, comprising a fixed base plate and a movable base plate. Vertical supports are longitudinally fixed to the left and right sides of the upper end of the fixed base plate. Ear plates are installed at the upper ends of the interior of each of the two supports. A swing block is suspended within each of the ear plates. A synchronous motor is fixed to the upper rear end of each of the two supports. A rotating shaft is installed at the shaft end of each of the two synchronous motors. The front ends of the two rotating shafts respectively rotate through the two ear plates. A connecting rod is movably installed at the movable end of each of the two swing blocks. Piston heads are movably mounted on the movable ends of the connecting rods. Two limiting cylinders are longitudinally fixed inside each of the two uprights by multiple fixed side plates. Limiting grooves are opened through the upper ends of the two limiting cylinders. The two piston heads slide at the two limiting grooves respectively. Multiple return springs are longitudinally arranged on the upper end of the fixed base plate. The movable base plate is horizontally mounted on the upper end of the multiple return springs. A recycling box is longitudinally fixed in the middle of the upper end of the movable base plate. A coarse screen is horizontally fixed in the middle of the inside of the recycling box. A suction fan is installed below the coarse screen. A fine screen is movably inserted into the lower front end of the recycling box.

[0006] Furthermore, the two swing blocks are respectively fixed to the outside of the two rotating shafts.

[0007] Furthermore, both synchronous motors are synchronously controlled by a PID controller.

[0008] Furthermore, the two piston heads are located on the left and right sides above the movable base plate, respectively.

[0009] Furthermore, a pull handle is installed at the front end of the fine screen.

[0010] Furthermore, the fine screen is located below the suction fan.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a stainless steel workpiece powder recovery device. Because this utility model adds an ear plate, synchronous motor, rotating shaft, swing block, connecting rod, limiting cylinder, piston head, movable base plate, return spring, recovery box, fine screen and coarse screen, our design improvements and actual use show that this device has a reasonable structure. It adopts a reciprocating piston and filter structure, which can drive the fine screen to vibrate continuously. This can prevent the 434 stainless steel metal powder falling on the fine screen from clogging or accumulating. Combined with the suction effect of the suction fan, it can ensure the efficiency of subsequent stainless steel workpiece powder recovery and has good practicality. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a stainless steel workpiece powder recovery device, including a fixed base plate 1 and a movable base plate 12. Vertical supports 2 are longitudinally fixed to the left and right sides of the upper end of the fixed base plate 1. Ear plates 3 are installed at the upper ends of the two supports 2. Swinging blocks 6 are suspended inside the ear plates 3. Synchronous motors 4 are fixed to the upper rear ends of the two supports 2. Rotating shafts 5 are installed at the shaft ends of the two synchronous motors 4. The front ends of the two rotating shafts 5 respectively rotate through the two ear plates 3. Connecting rods 7 are movably installed at the movable ends of the two swing blocks 6. Piston heads 11 are movably installed at the movable ends of the two connecting rods 7. Two limiting cylinders 9 are longitudinally fixed inside the two supports 2 via multiple fixed side plates 8. Each limiting cylinder 9 has a limiting groove 10 extending through its upper end. The two piston heads 11 slide at the two limiting grooves 10 respectively. Multiple return springs 13 are longitudinally arranged on the upper end of the fixed base plate 1. The movable base plate 12 is horizontally installed on the upper end of the multiple return springs 13. A recycling box 14 is longitudinally fixed in the middle of the upper end of the movable base plate 12. A coarse screen 18 is horizontally fixed in the middle of the inside of the recycling box 14. A suction fan 17 is installed below the coarse screen 18. A fine screen 15 is movably inserted into the lower front end of the recycling box 14. This design solves the problems of the original device, such as the fixed position of the fine screen, unreasonable structural design, easy blockage or accumulation of 434 stainless steel metal powder, slow processing speed, and impact on overall work efficiency.

[0019] In the first embodiment of this utility model: two swing blocks 6 are respectively fixed outside the two rotating shafts 5. By adding two swing blocks 6 and fixing them outside the two rotating shafts 5, the two swing blocks 6 can be driven to rotate inside the two ear plates 3 when the two rotating shafts 5 rotate. Both synchronous motors 4 are synchronously controlled by a PID controller. By adding two synchronous motors 4 and controlling them synchronously by a PID controller, the PID controller can control the synchronous rotation of the two synchronous motors 4. The two piston heads 11 are respectively located on the left and right sides above the movable base plate 12. When the two piston heads 11 are driven to move downward, they can strike the movable base plate 12, causing the movable base plate 12 to vibrate on multiple return springs 13.

[0020] A pull handle 16 is installed at the front end of the fine screen 15, which makes it easy for workers to pull out the fine screen 15. The fine screen 15 is located below the suction fan 17. The suction fan 17 is the suction device mentioned in the above-mentioned comparative document. In this utility model, it only plays an auxiliary adsorption role and will not be described in detail.

[0021] As a second embodiment of this utility model: When stainless steel workpiece powder is added into the recycling bin 14, two synchronous motors 4 are started. The two synchronous motors 4 drive two rotating shafts 5 to rotate, thereby causing two swing blocks 6 to rotate within two ear plates 3. The rotation of the two swing blocks 6 will drive two piston heads 11 to perform piston movement within two limiting cylinders 9 via two connecting rods 7 (Note: Refer to the piston principle in the prior art). During this process, when the two piston heads 11 are driven to move downward, they can strike the movable base plate 12, causing the movable base plate 12 to be activated by multiple return springs 13. Vibration is applied to the upper part, which in turn causes the recycling box 14 to vibrate, causing the coarse screen 18 and fine screen 15 inside the recycling box 14 to vibrate as well. This prevents the 434 stainless steel metal powder falling on the fine screen 15 from clogging or accumulating. Then, the suction fan 17 is started, which attracts the 434 stainless steel metal powder and effectively collects the 434 stainless steel metal powder scattered during the stainless steel processing. (Note: The added suction fan 17 is the suction device in the above-mentioned comparative document. In this utility model, it only plays an auxiliary adsorption role and will not be described in detail.)
