Problems solved by technology

The correct use of lubricating oil in the sheet metal stamping process will directly affect the service life of the stamping die, affect the fracture quality of the blanked parts, the forming dimensional accuracy and surface quality, and there is no lubricating oil for the stamping die in the stamping process. Therefore, in the stamping process, it is mainly used to apply lubricating oil to the surface of the mold and the sheet metal manually.
However, manual application of lubricating oil inevitably leads to cumbersome operation and low productivity; especially for sheets with oil film on the surface, it is easy to dissolve and gather the oil film due to uneven artificial application of lubricating oil, resulting in excessive lubricating oil, forming different colors. Color spots seriously affect the surface quality of stamping parts

Embodiment Construction

[0017] Referring to Fig. 1 and Fig. 2, the upper and lower dies of the automatic lubricating device of the stamping die are fixedly connected with the upper and lower die bases respectively by bolts, and the upper die 3 is provided with at least two or more holes passing through the upper and lower ends. Through holes 11, the number of through holes is related to the uniformity of lubrication of the plate, the more the number of through holes, and the distance between the through holes is evenly distributed, the better the uniformity of lubrication of the plate. The upper die base 1 is provided with holes equal in number and positions to the through holes 11 in the upper die, and these holes are communicated with the oil inlet hole 2 provided by the upper die base 1. The joint 10 is connected with an oil delivery pipe 6 with a flow regulating switch 5 , and the other end of the oil delivery pipe is connected with an oil reservoir 4 providing lubricating oil, and the position of...

Abstract

The invention relates to an automatically lubricant device of punch mould, which comprises upper and lower mould bases, and upper and lower moulds. Wherein, the upper and lower moulds are fixed with upper and lower mould bases; the upper mould has several through holes through the upper and lower ends; the upper mould base has relative holes; said holes are connected to one oil inlet of upper mould base; the oil inlet via one oil tube with one flux adjust switch is connected to the oil storage device which is higher than upper mould base; one end of lower mould base at material feeding end is mounted with one roller whose surface has blanket to lubricant the lower surface; the wall of roller has several small through holes; one end of spindle axle of roller has oil inlet via another oil tube with flux adjust switch connected to the oil storage device. The invention can lubricant the punch mould and sheet, to improve their service life and punch quality.

Description

technical field [0001] The invention relates to a stamping die, in particular to an automatic lubricating device for the stamping die which can evenly lubricate the front and back surfaces of a stamped sheet material. Background technique [0002] Sheet metal stamping has the characteristics of high material utilization and production efficiency, high shape and dimensional accuracy of stamped parts, and good interchangeability. The correct use of lubricating oil in the sheet metal stamping process will directly affect the service life of the stamping die, affect the fracture quality of the blanked parts, the forming dimensional accuracy and surface quality, and there is no lubricating oil for the stamping die in the stamping process. Therefore, in the stamping process, the manual method is mainly used to apply lubricating oil to the surface of the mold and the sheet. However, manual application of lubricating oil inevitably leads to cumbersome operation and low productivity...
