Abstract

The invention relates to a self-lubricating multi-station progressive die. The progressive die comprises an upper die body and a lower die body, the upper die body comprises an upper die base (5), anupper backing plate (6) and a convex die fixing plate (7) which are sequentially connected with one another from top to bottom, and convex die punches (8) are fixed in the convex die fixing plate (7);the die further comprises a self-lubricating device of the convex die punches (8), and the self-lubricating device comprises outer oil nozzles (1) connected to an external oil source, an oil nozzle fixing plate (2), an oil pipe (3) and inner oil nozzles (4). Oil leakage holes (11) are distributed between the convex die punches (8), the starting ends of the oil leakage holes (11) are communicatedwith an oil storage tank (10), the tail ends of the oil leakage holes (11) are communicated with the convex die punches (8), and the convex die punches (8) are fixed in the convex die fixing plate (7).

Description

(1) Technical field [0001] The invention relates to a multi-station progressive die. (2) Background technology [0002] The punching speed of the multi-station progressive die is fast, and the punch of the punch is prone to heat. During the blanking process of the strip, there is powder, which is easy to stick to the surface of the punch, causing the surface of the punch to wear, and even strain and break. Usually, there is an oiling device at the feeding mechanism at the front end of the mold, and the lubricating oil drops onto the surface of the material belt, and is brought into the mold through the conveyor belt of the material belt to lubricate the punch. However, some punches have complex shapes or there are many local punches, and the lubricating oil of the strip cannot satisfy the lubrication effect on all the punches. At this time, it is necessary to design a local lubricating mechanism. (3) Contents of the invention [0003] Aiming at the problem that some punch...
