An automatic lubricating and cooling mechanism for stamping punch

Abstract

The invention discloses an automatic lubricating and cooling mechanism for stamping male dies. The automatic lubricating and cooling mechanism comprises an oil cup, wherein an oil outlet end of the oil cup is parallel and level to the lower end of a fixing plate and is connected with a first oil tube in parallel; the other end of the first oil tube is connected with one end of an adjusting valve; the other end of the adjusting valve is connected with a second oil tube; the other end of the second oil tube is communicated with an oil storage cavity; a first oil seal and a second oil seal are respectively arranged at two ends of the oil storage cavity; the oil storage cavity is formed in a discharging plate of a die; a punch penetrates in the oil storage cavity; the first oil seal and the second oil seal are arranged between a die head and a die shank of the punch; and the oil pressure between the oil cup and the oil storage cavity keeps balanced by adjusting the adjusting valve. When the punch moves in the up-down direction, a die rod positioned between the die head and the die shank are always soaked in stamping oil in the oil storage cavity partially, and the punch is always lubricated and cooled down by the stamping oil. By the automatic lubricating and cooling mechanism for the stamping male dies, the safety of workers, the efficiency and the quality of the stamping male dies are greatly improved, and the service lives of the stamping male dies are greatly prolonged.

Description

technical field [0001] The invention relates to an automatic lubricating and cooling mechanism for a stamping punch. Background technique [0002] Stamping punches in existing production such as figure 1 As shown, it is composed of fixed plate A1, punch A2, unloading backing plate A3, unloading plate A4, belt material A5, and concave template A6; there is no automatic lubrication and cooling mechanism for stamping punch A2, The lubrication of the punch A2 depends on manual work such as figure 1 Manually apply lubricating zone 7 as shown or apply lubricating oil on strip A5 to increase lubrication and reduce temperature. [0003] Due to the failure to lubricate and cool down in time during production, the wear of the punch head A2 and the discharge plate A4 is often increased, and the life of the die is shortened; at the same time, the die needs manual lubrication and maintenance after a certain period of production, and sometimes the die needs to be disassembled. It is tr...

[0002] Stamping punches in existing production such as figure 1 As shown, it is composed of fixed plate A1, punch A2, unloading backing plate A3, unloading plate A4, belt material A5, and concave template A6; there is no automatic lubrication and cooling mechanism for stamping punch A2, The lubrication of the punch A2 depends on manual work such as figure 1 Manually apply lubrication zone 7 as shown or apply lubricant to strip A5 to increase lubrication and reduce temperature

[0003] Due to the failure to lubricate and cool down in time during production, the wear of the punch head A2 and the discharge plate A4 is often increased, and the life of the die is shortened; at the same time, the die needs manual lubrication and maintenance after a certain period of production, and sometimes the die needs to be disassembled. It is troublesome; it is difficult to ensure the continuous production of the mold, which affects the efficiency; due to manual lubrication, the parts are stained with grease, and it is necessary to increase the degreasing process of the parts, which is not allowed for parts with special requirements; manual lubrication maintenance will cause personnel injuries Potential safety hazards and increased labor costs
