Adjusting mechanism of the top stopping point of the floated mould frame mandril of powder forming machine

Abstract

The floating upper dead center regulating mechanism for the die holder mandrel in powder forming machine includes one piston rod inside the cylinder, one worm case with connected worm and worm gear and fixed on the cylinder, one upper limit sleeve connected to the piston rod and the worm gear, and one locating key on the cylinder and fitting the upper limiting slot in the upper limit sleeve. The floating upper dead center regulating mechanism has simple structure, convenient operation, low production cost, high regulating precision and capacity of ensuring high precision of the pressed product.

Description

technical field [0001] The invention relates to an important component in a powder forming machine, which is a floating top dead center adjustment mechanism for the mold base core rod of the powder forming machine used for adjusting the position of the mold base core rod. Background technique [0002] Because the powder forming machine can press high-precision, multi-step parts at one time, and has the characteristics of wide application range, high production efficiency and high material utilization rate, it has been favored by enterprises and has been widely used in various metals and ceramics. , bakelite and other powder products, and the shape of the pressed products is becoming more and more complex. Parts with multi-step shapes, parts with through holes in the middle, and parts with multi-step through holes in the middle can be pressed out. [0003] Patent application number CN200510062212.3 "Die Floating Adjustment Mechanism for Powder Forming Machine" provides a meth...

Problems solved by technology

[0005] Due to the variety of parts produced by the enterprise, it is necessary to prepare a lot of pads, which not only is troublesome to process but also consumes a lot of materials, which brings a lot of inconvenience to the management of the enterprise. At the same time, it is difficult to achieve the dimensional accuracy of the parts produced by this method. The operation is cumbersome, and the spacer needs to be replaced every time a product is produced. At this time, the adjustment nut and the limit plate need to be disassembled from the cylinder block, and then the spacer of the required size can be added. Put the adjustment nut and the limit plate back to their original positions, use screws to pass through the through holes on the limit plate, the adjustment nut, and the spacer, and fix the spacer on the cylinder block, so that it can work again. The base part of the machine is installed in the foundation pit, each time the operator must go down into the foundation pit to replace it, because the location of the foundation pit is small, it is difficult to operate, and the disassembly and assembly of parts is troublesome, time-consuming, labor-intensive, and labor-intensive. figure 2 As shown, 18 is the adjusting nut, 19 is the limit plate, and 20 is the spacer
