Warm forging die spiral spraying, cooling and lubricating device applicable to automatic mechanical press

Abstract

The invention provides a warm forging die spiral spraying, cooling and lubricating device applicable to an automatic mechanical press. The device comprises a guide sleeve, a first fixed sleeve and a second fixed sleeve, wherein the guide sleeve is mounted at the top of a die and is provided with a central hole used for a punch to pass through; the central hole is coaxially arranged with the cavityof the die; a plurality of damping holes are formed in the guide sleeve; the damping holes penetrate the inner wall of the guide sleeve to the outer wall of the guide sleeve; the damping holes are linear; the plurality of damping holes are spirally arranged; openings of the damping holes, which are formed in the inner wall of the guide sleeve, are lower than openings of the damping holes, which are formed in the outer wall of the guide sleeve; the first fixed sleeve sleeves the guide sleeve and is provided with a first through hole penetrating the inner wall and the outer wall; the first through hole is linear; the second fixed sleeve sleeves the first fixed sleeve and is provided with a second through hole penetrating the inner wall and the outer wall; the second through hole is linear.The device adopts a double-angle combination manner to spray, cool and lubricate the die on the automatic mechanical press through die spiral, is applicable to common cavities and complex cavities, greatly prolongs the service life of the die and improves the product appearance quality, and reduces the manufacturing cost.

Description

technical field [0001] The invention belongs to the field of cooling and lubricating devices, and more specifically relates to a spiral spray cooling and lubricating device suitable for warm forging dies of automatic mechanical presses. Background technique [0002] At present, the domestic commonly used die spray cooling and lubrication devices mainly have the following status and problems: [0003] 1. Ordinary warm forging production lines are still produced by manual spray cooling and lubrication. However, due to artificial uncertainty and uncontrollability, the life of the mold may be high or low, which also has a great impact on the stability of product performance. Zhengda gradually Be eliminated, or can only adapt to the maintenance market. [0004] 2. The automatic production line adopts the method of spraying the die at an angle. This method has no problem for products with simple cavities, but for dies with complex cavities, some parts of the die cannot be sprayed...

AI Technical Summary

Problems solved by technology

[0003] 1. Ordinary warm forging production lines are still produced by manual spray cooling and lubrication. However, due to artificial uncertainty and uncontrollability, the life of the die may be high or low, which also has a great impact on the stability of product performance. Zhengda gradually Be eliminated, or can only adapt to the maintenance market

[0004] 2. The automatic production line adopts the method of spraying the die at an angle. This method has no problem for products with simple cavities, but for dies with complex cavities, some parts of the die cannot be sprayed, resulting in roughening and damage to the die. Phenomenon

[0005] The disadvantages of this device are: the life of the die is low, the production cost is high, and the production efficiency is low.
