Description

Technical Field

[0001] The present invention relates to the technical field of ball valve stamping, and particularly to a stamping device for processing ball valves with a self-lubricating structure. Background Art

[0002] When processing ball valves, the processing of related accessories can be perforated by stamping. In addition to stamping, there are also some drilling processing methods. Compared with drilling, stamping has less burrs and faster processing speed, and is widely used in the ball valve processing technology.

[0003] Prior Art 1 (a Chinese patent with application number CN202420062892.7, published on August 9, 2024) is a low-noise stamping device for processing hard-sealed ball valves, including a processing table. At the top of the processing table, there is a processing station. Between the four end corners at the bottom of the processing station and the processing table, there are support frames for supporting the processing station. On the processing station, there is a positioning assembly for positioning and clamping a valve body that is open at both the top and bottom and is cylindrical. On one side of the processing table, there is a support table. On the support table, there is a lifting block through a lifting assembly. At the bottom of the lifting block, there is an installation plate through a connecting rod. At the bottom of the installation plate, there is a stamping module for stamping the valve body. This low-noise stamping device for processing hard-sealed ball valves, through the mutual cooperation of the protective cover, sound insulation board, and sound insulation cotton in the sound insulation cavity, plays a certain role in sound insulation and noise reduction, and then can keep the whole device in a low-noise state during operation. Prior Art 2 (a Chinese patent with application number CN202320857814.1, published on September 12, 2023) is a full-welded ball valve middle body punching machine, including a base. At the upper end of the base, a plurality of columns are fixedly installed. At the upper ends of the plurality of columns, a top plate is fixedly installed together. At the upper end of the top plate, a hydraulic cylinder is fixedly installed. At the telescopic end of the hydraulic cylinder, a punch is fixedly installed. At the upper end of the base, a fixed plate is fixedly installed. On the upper end of the fixed plate, a translation plate is slidably connected. On the opposite sides of the two translation plates, a positioning disk and a support column are respectively fixedly installed. On the fixed plate, there is a translation mechanism for the translation plate to move towards each other. This application uses the cooperation of the support column and the positioning disk to play the role of supporting and fixing the workpiece. In the stamping state, it can ensure that the deformation amount of the workpiece is within the qualified range, and complete the opening through stamping, reducing the existence of burrs.

[0004] At present, when the current stamping device is performing stamping operations, the temperature of the stamping head is relatively high during repeated stamping, and the resulting friction is also relatively large. Currently, for some stamping equipment with lubrication for the stamping head, most of the lubrication adopts the manual lubrication method, which is relatively cumbersome in operation, has low usability, and when loading and unloading the product during stamping, operating under the stamping head poses certain safety hazards, and it is also not conducive to the continuous progress of stamping work.

Through the spraying method, the stamping head can be effectively lubricated before stamping, making the subsequent stamping smoother.

[0019] (4) Through the setting of the limiting block, the product in the feeding groove can be limited. When the product moves under the stamping head, the limiting block is controlled to move, and multiple groups of limiting blocks can move synchronously to center and lock the product, making the subsequent stamping position stable and improving the stamping quality.

[0020] (5) Through the connection between the positioning head and the positioning hole, the positioning effect of the rotation of the feeding tray can be achieved, making the position of the feeding tray stable during subsequent stamping. When the subsequent positioning head disengages from the connection with the positioning hole, the feeding tray can continue to rotate. Description of the Drawings

The top block 18 pushes the piston 12 to move upward through the guiding block 17, squeezing out the oil body in the storage chamber 11, and making it spray out through the nozzle 9. When the trigger rod 19 disengages from the arc-shaped block 20, the piston 12 resets downward, and the oil body in the oil storage chamber 8 enters the storage chamber 11 through the second communication groove 14 and the second one-way valve 15 to prepare for the next lubrication.
