Problems solved by technology
Since the gap between the punching convex and concave dies and the fixed plate is very small, to disassemble the punching convex and concave dies, the punching sub-mold must be disassembled, and then the punching convex and concave dies must be removed from the fixed plate with tools. Knocking out the reverse side, this method brings a lot of inconvenience to the assembly and debugging personnel, and also wastes time, which seriously affects the daily production efficiency

The invention relates to a puller used for dismounting a punching male die or a punching female die. The puller comprises a die sleeve, a locking screw, a pulling mat and a pulling screw, wherein the die sleeve has a cup-shaped structure and an opened head end; the inner diameter of the die sleeve is larger than the outer diameters of the punching male die and the punching female die; a radial screw hole is formed on a wall of the die sleeve and penetrates the wall; the locking screw is arranged in the screw hole; and the tail end of the die sleeve is connected with the pulling screw which is provided with the pulling mat used for applying pulling force. The puller has the characteristics of simple and smart structure, convenient operation and strong adaptability, and can pull out the punching male die and the punching female die from a fixing plate conveniently by only sleeving the die sleeve on the punching male die and the punching female die and tightening up the die sleeve by using the locking screw without dismounting punching sub-dies and striking on reversed sides during dismounting the punching male die and the punching female die.
Description
technical field [0001] The invention belongs to the technical field of stamping dies, and relates to a puller for disassembling punching punches or dies. Background technique [0002] At present, the traditional tube-fin heat exchanger is the main form of heat exchange for household air conditioners, central air conditioners, vehicle air conditioners and fan coil units. Air-conditioning fins are an important part of tube-fin heat exchangers. Air-conditioning fins are generally stamped by air-conditioning fin dies. Front, slitting, feeding and cross cutting. The punching process is realized by punching sub-die. The mechanism of the punching sub-mold is as follows: Figure 4 As shown, the punching sub-mold mainly includes a punching punch 6 and a punching die 7 that cooperate with each other. The punching punch 6 is assembled in the punch fixing plate 9, and the punching die 7 is assembled in the die fixing plate 8. The punching punch 6 and the punching die 7 are vulnerable...
