[0021] Reference Figure 1 、 Figure 2 、 Figure 3A progressive die encircling mechanism 8 is provided on the base 1. The progressive die encircling mechanism 8 includes a die bridge 81. The upper end of the base 1 is fixedly connected to the die bridge 81. The outer side of the die bridge 81 is slidably sleeved with a progressive die body 82. The left end of the base 1 is fixedly connected to a fixing frame 83. The vertical part of the fixing frame 83 is fixedly installed with a cylinder 84. The telescopic end of the cylinder 84 is fixedly connected to the die bridge 81. The horizontal part of the fixing frame 83 is fixedly connected to an oil storage cylinder 85. The inner wall of the oil storage cylinder 85 is slidably connected to a push rod 86. The upper end of the push rod 86 is fixedly connected to a push plate 861 The push plate 861 is slidably connected to the oil storage cylinder 85. The interior of the oil storage cylinder 85 is fixedly connected with a guide tube 88. The guide tube 88 is fixedly connected to the fixed frame 83. The upper end of the guide tube 88 is fixedly connected with an oil-absorbing cotton sleeve 890. The oil-absorbing cotton sleeve 890 is slidably connected to the telescopic end of the cylinder 84. By pushing the push rod 86 to move, the push plate 861 is driven to move, the lubricating oil is pushed, and in conjunction with the functions of the guide tube 88, the oil-absorbing cotton sleeve 890 and other structures, the telescopic end of the cylinder 84 can be lubricated to reduce the telescopic resistance of the cylinder 84.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 There are two mold bridges 81, which are symmetrically distributed on the base 1.

[0023] The specific implementation process of the utility model is as follows: when in use, the starting motor 2 drives the output shaft to rotate, thereby driving the forward and reverse threaded screw rods 3 to rotate. Since the threads on the surfaces of the forward and reverse threaded screw rods 3 are symmetrically distributed and in opposite directions, under the relationship of the threaded connection, the two moving blocks 4 can be driven to move toward each other, thereby driving the clamping plate 5 to move, and the position of the clamping plate 5 can be adjusted, thereby adaptively clamping and fixing hardware of different sizes;

[0024] Start the cylinder 84 to drive the telescopic end to move, so as to push the progressive die 82 to slide along the surface of the die bridge 81, so that the progressive die 82 contacts the hardware and extrude and round the hardware. The push rod 86 can be pushed to move upward to drive the push plate 861 to move. The spring 87 is deformed to push the lubricating oil. Under the action of the feed hopper 89 and the guide tube 88, the lubricating oil can be diverted so that the lubricating oil contacts the oil-absorbing cotton sleeve 890 and finally contacts the telescopic end of the cylinder 84, lubricating the cylinder 84 to reduce the telescopic resistance of the cylinder 84.
