Double-up-stroke detrusion regulating mechanism of powder shaping mill

Abstract

The invention provides a double-upstroke outstroke adjusting mechanism for powder forming machines, which comprises an air-feed guide seat with an air duct, a sealing base, a regulating nut, an outstroke seat, an in-stroke seat and an in-stroke cylinder body, as well as a regulating device fixed on a fixing device, wherein the regulating device consists of a cylinder, the air-feed guide seat, a bottom plate and a guide pole; the cylinder is fixed on the air-feed guide seat and the bottom plate; the bottom plate is fixed on the outstroke seat; and the bottom plate is matched with the guide pole arranged on the air-feed guide seat through a guide sleeve. The prior powder forming machine is not provided with the adjusting mechanism, and due to the arrangement of the mechanism with simple structure and easy manufacture, when a pressed product is demolded, the cylinder supplies air to enable the outstroke seat not to move downwards but follow the bottom plate to move upwards, so as to reduce the stroke of the in-stroke seat, namely the product can be pushed out only though a short distance of movement of the in-stroke seat. The mechanism has the advantages that the mechanism is high in pressing speed, improves work efficiency, reduces cost and equipment investment, can use the prior powder forming machine to process and manufacture the products with high upper steps and complex shapes, and improves processing precision because of the positioning of the guide pole.

Description

technical field [0001] The invention relates to an important component part in a powder molding machine, especially one used in conjunction with a multi-layer lower template in a mold base, which can be used to process products with complex shapes, high upper steps and high quality precision at one time. The powder forming machine has double upper punch and outer punch adjustment mechanism. Background technique [0002] Patent No. 01239491.2 "Double Upper Punch Mechanism of Powder Molding Machine Mold Base" provides a kind of inner and outer two punching seats installed on the inner punching cylinder body at the same time, which is used to process more complex parts with more than two steps at one time. The lower end of the inner punching cylinder is connected with a rotatable adjusting nut, but this adjusting nut can only adjust the size of the stroke of the outer punching seat, and can only move downward in one direction, and cannot move in a controlled manner in both dire...

Problems solved by technology

[0004] However, the outer punch seat on the existing powder molding machine can only move upward when the lower mold base is working upward against the mold. The outer punch seat can only move downward, and cannot move in two directions. The product cannot be removed during the stroke of the flushing seat, such as image 3 As shown in d, it is impossible to process powder products with high upper step shape with the existing powder forming machine
