Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular to a stainless steel plate punching equipment. Background Art

[0002] Stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-proof. Stainless steel plate refers to steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to steel plate that is resistant to corrosion by chemically corrosive media such as acid, alkali and salt.

[0003] Blanking is a stamping process that uses a die to separate sheet materials, including blanking, punching, notching, cutting, trimming, etc. It can be used to make parts or prepare blanks for bending, drawing, forming and other processes. Punching parts (or blanks) of the required shape from sheet materials is called blanking, and punching holes of the required shape on the workpiece (the material punched out is waste) is called punching.

[0018] The technical effects and advantages of the present invention:

[0019] 1. When the present invention performs blanking operations on stainless steel plates, the formed plates are taken out by the material automatic export mechanism. After blanking is completed, the formed plates fall on the top of the turning plate. At this time, operate the fourth driving motor to make the fourth driving motor drive the third one-way threaded screw rod to rotate. The third one-way threaded screw rod drives the quadrilateral movable frame to move up and down through the sixth nut. When the quadrilateral movable frame moves downward, it drives the support plate to move downward. The support plate drives the connecting frame to move downward. The connecting frame drives the formed plates to move downward through the connected turning plate. Then operate the second electric telescopic rod to make the turning plate turn over, so that the formed plates slide downward on the turning plate, so that the formed plates can slide onto the conveyor belt on one side for transmission. Finally, the formed plates are transmitted into the finished product collection box through the conveyor belt, achieving the effect of automatically collecting finished product materials, eliminating the need for manual material collection, improving safety, reducing the labor burden, and improving work efficiency.

[0020] 2. Before the blanking operation of the stainless steel sheet, the automatic feeding mechanism is used to automatically feed the sheet to be processed. The sheet to be processed is placed above multiple groups of conveyor rollers, and then the first driving motor is operated so that the first driving motor drives the driving shaft to drive the driving rotating shaft to rotate. The driving rotating shaft drives the driving sprocket to rotate, the driving sprocket drives the chain to drive, the chain drives multiple groups of driven sprockets to rotate, and when the multiple groups of driven sprockets rotate, they drive multiple groups of driven rotating shafts to rotate, and the driven rotating shafts drive the conveyor rollers to rotate. In this way, the sheet to be processed can be automatically conveyed, so that it can reach the specified blanking position for blanking operation, without manually pushing the sheet, which improves the automation degree of feeding;

[0021] 3. Before the blanking operation of the stainless steel sheet, the positioning mechanism is used to position the sheet to be processed. When the sheet to be processed reaches below the infrared emitter, the infrared rays emitted by the infrared emitter are blocked, so that the infrared receiver cannot receive the infrared rays. In this way, the connected first driving motor is controlled by the controller to stop working, so that the sheet to be processed stops advancing. At this time, the sheet to be processed can accurately stop at the specified position, so as to achieve the effect of accurate positioning;

[0022] 4. Before the blanking operation of the stainless steel sheet, the die switching mechanism is used to switch and use different dies. The third driving motor is operated so that the third driving motor drives the driving shaft to drive the second single-direction screw rod to rotate. The second single-direction screw rod drives two groups of movable plates to move horizontally through two groups of third screw nuts. When the movable plate where the frame-shaped blanking die is located moves to the corresponding position, at this time, the frame-shaped blanking die can perform the blanking operation, so as to achieve the effect of automatically switching different dies;

[0023] 5. Before the blanking operation of the stainless steel sheet, the first disassembly and assembly mechanism is used to disassemble, assemble and replace the frame-shaped blanking die. The second electric motor is operated so that the second electric motor drives the driving shaft to drive the second left-right screw rod to rotate. The second left-right screw rod drives two groups of first guide plates to move towards or away from each other through two groups of fourth screw nuts. The two groups of first guide plates play a role in driving the two groups of square inserts to move towards or away from each other. In this way, the frame-shaped blanking die can be disassembled, which is convenient for replacing different frame-shaped blanking dies;

[0024] 6. When the present invention performs blanking operations on stainless steel sheets, the waste sheet after blanking is pulled out by a waste sheet pulling mechanism. First, operate the first electric motor so that the first electric motor drives the first left - right screw rod to rotate through the drive shaft. The first left - right screw rod drives two sets of second nuts to drive two sets of clamping plates to move towards each other, thereby being able to clamp and fix the sheet to be processed. Then, operate the second drive motor so that the second drive motor drives the first single - threaded screw rod to rotate. The first single - threaded screw rod drives the moving plate to move towards the installation table side through the first nut, so that the moving plate drives the clamping and fixing mechanism above, thus achieving the effect of pulling the waste sheet. When it is pulled to one end of the installation table, operate the first electric motor again so that the two sets of clamping plates move in opposite directions, so that the two sets of clamping plates release the fixation of the waste sheet. Under the action of gravity, the waste sheet can automatically fall into the waste collection box for centralized collection, thereby improving the recycling efficiency of waste materials.

[0049] Working principle: When in use, first place the plate 4 to be processed on the multiple groups of conveyor rollers 307, and then operate the first driving motor 301 to make the multiple groups of conveyor rollers 307 rotate, so that the plate 4 to be processed is automatically fed. When it reaches the specified position, then operate the third driving motor 702 to make the third driving motor 702 drive the second one-way threaded lead screw 703 to rotate through the drive shaft. The second one-way threaded lead screw 703 drives the two movable plates 705 to move horizontally through the two third nuts 704. When one of the movable plates 705 where the frame blanking die 810 or the cylindrical blanking die 909 is located moves to the corresponding position, at this time, the frame blanking die 810 or the cylindrical blanking die 909 can perform the blanking operation. Then operate the electric cylinder 709 to make the electric cylinder 709 drive the convex plate 711 below to move downward through the telescopic shaft 710. In this way, the convex plate 711 drives the installed frame blanking die 810 or the cylindrical blanking die 909 to perform downward stamping, so that the plate 4 to be processed can be blanked, and the effect of forming the formed plate 11 can be achieved. When the blanking is completed, the formed plate 11 falls on the turning plate 1015. At this time, operate the fourth driving motor 1002 to make the fourth driving motor 1002 drive the third one-way threaded lead screw 1003 to rotate. The third one-way threaded lead screw 1003 drives the quadrilateral movable frame 1005 to perform a lifting movement through the sixth nut 1004. When the quadrilateral movable frame 1005 moves downward, it drives the support plate 1006 to move downward. The support plate 1006 drives the connecting frame 1007 to move downward. The connecting frame 1007 drives the formed plate 11 to move downward through the connected turning plate 1015. Then operate the second electric telescopic rod 1011 to make the turning plate 1015 turn over. In this way, the formed plate 11 slides downward on the turning plate 1015, so that the formed plate 11 can slide onto the conveyor belt 1206 on one side for transmission. Finally, the formed plate 11 is transmitted into the finished product collection box 13 through the conveyor belt 1206, achieving the effect of automatically collecting the finished product materials, eliminating the need for manual material collection, improving safety, reducing the labor burden, and improving work efficiency.
