Filling regulating and limiting device for powder forming machine

Abstract

A powder forming machine filling adjustment limit device, which is composed of a cross arm lifting mechanism and a mold base filling adjustment mechanism connected to the cross arm. The mold base filling adjustment mechanism consists of two guide seats fixed on the cross arm, and a machine under the cross arm. A fixed seat is fixed on the frame, and the piston rod is slidably fitted in the cylinder body fixed with the cylinder head and the oil pipe to form an adjustment mechanism. There is a moving distance between the piston rod and the cylinder body. Composed of worm and worm gear connections. The independent cross arm structure is used to replace the original assembly consisting of the cross arm and the swing arm. The structure is simple and easy to process. The cylinder drives the cross arm to move up and down, with uniform force and good stability, and the oil pressure in the cylinder is adjusted. From no pressure to pressure, and make the oil pressure greater than the upward ejection force of the filling cylinder, the cross arm drives the female mold to descend for more filling, on the contrary, the female mold rises for less filling, suitable for installation and use on large-tonnage molding machines. Pressed products with multiple steps and complex shapes.

Description

technical field [0001] The invention relates to an important component in mechanical processing equipment, in particular to a powder forming machine filling adjustment limit device for controlling and adjusting the filling amount of the female mold of the powder forming machine. Background technique [0002] The powder forming machine can press powder metallurgy parts with high precision and good finish at one time, which is favored by enterprises. [0003] The filling mechanism mentioned in CNZL0228756.1 "Powder Forming Machine" is to automatically complete the powder filling and the automatic demoulding of the pressed product through the swing arm driving the matching cross arm to move up and down in parallel. For the swing arm on the frame, one side of the swing arm is the shaft, and the other side is the boom. The pressure roller and the pressure roller shaft connected with the bearing need to be installed on the boom, and the cross arm is driven by the pressure roller. ...

Problems solved by technology

[0003] The filling mechanism mentioned in CNZL0228756.1 "Powder Forming Machine" is to automatically complete the powder filling and the automatic demoulding of the pressed product through the swing arm driving the matching cross arm to move up and down in parallel. For the swing arm on the frame, one side of the swing arm is the shaft, and the other side is the boom. The pressure roller and the pressure roller shaft connected with the bearing need to be installed on the boom, and the cross arm is driven by the pressure roller. The structure of this mechanism is complicated. It is bulky, difficult to process and difficult to install, and only one side of the cross arm is stressed when it is working, and the force is unilateral and uneven, so the working stability is poor, and it can only press low precision and regular shapes. products
