Abstract

The invention provides a punch lubricating mechanism. The punch lubricating mechanism comprise an external oil nozzle (1), an oil nozzle fixing plate (2), an oil pipe (3), an internal oil nozzle (4),an upper die holder (5), an upper backing plate (6), a punch fixing plate (7) and punches (8), wherein the oil nozzle fixing plate (2) is arranged on the top of the upper die holder (5), and the external oil nozzle (1) is fixed to the oil nozzle fixing plate (2); one end of the oil pipe (3) is connected with the external oil nozzle (1), the other end of the oil pipe (3) is connected with the internal oil nozzle (4); the internal oil nozzle (4) is fixed to the upper die holder (5), and a clearance groove of the oil pipe (3) and a clearance hole of the internal oil nozzle (4) are formed in the upper portion of the upper die holder (5); an oil storage tank (10) is arranged on the lower portion of the upper die holder (5) and communicated with the upper portion of the upper die holder (5); oilleakage holes (11) are formed in the bottom of the upper backing plate (6), the oil leakage holes (11) are distributed between the punches (8), the starting ends of the oil leakage holes (11) are communicated with the oil storage tank (10), the tail ends of the oil leakage holes (11) are communicated with the punches (8), and the punches (8) are fixed into the punch fixing plate (7).

Description

(1) Technical field [0001] The invention relates to an oiling and lubricating mechanism for a punch of a punch. (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 ...
