The invention provides a die for punching and flanging a loader oil shield, which has a simple structure, greatly reduces the maintaining frequency, is convenient and quick to discharge materials, solves the problems that blocking occurred easily, and increases the production efficiency. The die comprises an upper die and a lower die, wherein the upper die is arranged on a sliding block, and the lower die is arranged on a cushion board at a working table; a fixing plate buckled to the upper die is sleeved outside the lower die; the fixing plate is connected and positioned to the cushion board through a guide column; an unloading plate is arranged above the fixing plate in a manner of pressing; the guide column extends into the unloading plate; a gorgerin is arranged at the upper end of the guide column; and a spring is arranged between the gorgerin and the top wall of a chamber in the unloading plate for containing the guide column.
Description
technical field [0001] The invention relates to a punching and flanging die, in particular to a die for punching and flanging an oil cover of a loader. Background technique [0002] At present, punching and flanging dies are often used in metal plate cold processing and other industries, but the overall processing cost of the die is relatively high, and the quenching hardness is not easy to achieve, and it is easy to break. When the amount of processed products is relatively large, the die is easily damaged and maintenance The frequency is also relatively high, which greatly prolongs the production cycle of the parts, and the waste is not easy to discharge, and it is easy to block the discharge hole. Contents of the invention [0003] In view of the above problems, the present invention provides a die for punching and flanging the oil cover of the loader, which has a simple structure, greatly reduces the frequency of maintenance, and can discharge materials conveniently an...
