Description

Technical Field

[0002] During the manufacturing process of the valve, a punching device is required to apply high pressure to the workpiece through a die to punch the material into a hole of the desired shape. Commonly used punching devices include punching machines, punching machines, etc. For example, an electric punching machine disclosed in the patent with application number CN201620272846.5 includes a housing, a motor and a reducer. The motor is arranged in the housing and covered by a cover plate. It is characterized in that: a chip removal port is provided on any side of the housing, a bracket is provided at the upper end of the housing, the reducer is installed on the bracket, the input shaft of the reducer is connected to the motor through a belt, the output shaft of the reducer is connected to the punching assembly, the lower end of the punching assembly is provided with a punching die, the punching die is detachably installed on the upper end surface of the housing, and a through groove corresponding to the punching assembly is provided at the installation position of the punching die, and the through groove is communicated with the chip removal port;

[0003] During use of the existing valve casting punching device, the workpiece is not clamped stably enough and is prone to movement during the punching process, resulting in reduced punching accuracy. At the same time, the waste generated by the workpiece during the punching process is discharged through the chip discharge port, requiring workers to place a collection box under the chip discharge port and always pay attention to the collection situation to replace the collection box. During the replacement of the collection box, the waste is easily scattered on the ground during the replacement gap, requiring additional cleaning and collection after the work is completed, which increases the workload of the workers, and therefore it is necessary to make improvements. Utility Model Content

[0052] Clamping mechanism

[0053] The clamping mechanism 5 includes a clamping plate 6 with a plurality of anti-slip protrusions 60; the plurality of anti-slip protrusions 60 are arranged on the clamping surface of the clamping plate 6. The clamping mechanism 5 also has a conventional driving part. The driving plate is generally a hydraulic cylinder. The clamping plate 6 is installed at the driving end of the driving part. The clamping mechanism 5 has at least two and is symmetrically distributed on both sides of the punching table 2. Through the arrangement of the plurality of anti-slip protrusions 60, the anti-slip protrusions 60 of the clamping plate 6 can effectively increase the friction between the workpiece and the clamping plate 6 when clamping the workpiece, thereby preventing the workpiece from moving and improving the punching accuracy.

[0054] Splint

[0055] The clamping plate 6 also includes: an air cavity 61, which is arranged in the clamping plate 6 and runs through the clamping plate 6, and a suction nozzle 62 is arranged on one end of the air cavity 61 located on the clamping surface of the clamping plate 6; a first piston 63, which is arranged in the air cavity 61 and located on a side close to the suction nozzle 62; a limiting portion 64, which is arranged in the air cavity 61 and located between the first piston 63 and the suction nozzle 62, and the limiting portion 64 is used to limit the first piston 63 from moving toward the suction nozzle 62; a second piston 65, which is arranged in the air cavity 61 and located on a side of the air cavity 61 close to the back of the clamping plate 6; a mounting portion 66, which is arranged in the air cavity 61 and located on a side of the second piston 65 close to the first piston 63, and the mounting portion 66 is connected to the second piston 65 through an elastic member 67; a connecting rod 68, which is arranged in the air cavity 61, and the two ends of the connecting rod 68 are respectively connected to the first piston 63 and the second piston 65;

The connection between the air passage and the air cavity 61 is located between the second piston 65 and the first piston 63 .

[0057] After the workpiece is placed on the punching table 2, the clamp 6 moves toward the workpiece and clamps it. The anti-slip protrusion 60 is compressed during the process of the clamp 6 clamping the workpiece, and the air in the cavity enters the airway. As the air enters the airway, the pressure in the air cavity 61 increases, thereby driving the second piston 65 to move toward the rear side of the clamp 6. The movement of the second piston 65 drives the first piston 63 to move, thereby generating a negative pressure space between the first piston 63 and the suction nozzle 62. The suction nozzle 62 then sucks the workpiece, further preventing the workpiece from moving during the punching process. After the clamp 6 is separated from the workpiece, the second piston 65 drives the first piston 63 to reset under the action of the elastic member 67 to prepare for the next punching operation.
