Problems solved by technology
In addition, the traditional connecting rod manufacturing process mostly uses the sand method to pour under the action of gravity, and its pouring system usually has only one pouring cavity, so the pouring efficiency is low
However, with the increasing market demand for air compressor connecting rods, the traditional pouring system can no longer meet the demand, so it is urgent to develop a pouring system that can pour multiple air compressor connecting rods at the same time

Embodiment 1
[0024] In this embodiment, the pouring system is designed to produce four air compressor connecting rods in one pouring, and the low-pressure pouring process parameters can be adjusted according to the experimental needs, so that more connecting rods can be produced in a single pouring.
[0025] Such as Figure 2~3 As shown, an air compressor connecting rod pouring system includes a riser pipe 1, an I-shaped runner 2, a strip runner 3, an air compressor connecting rod 4, an exhaust 5, and an I-shaped runner 2 under the rib It is connected with the riser pipe 1; four strip sprues 3 are respectively arranged above the flanges of the four corners of the I-shaped sprue 2, and communicated with the I-shaped sprue 2; each strip sprue 3 has a space above it. The compressor connecting rod 4 and the exhaust hole 5 communicate with the air compressor connecting rod 4 .
[0026] In order to prevent the pouring processes of different sprues 3 from interacting, the sprue 3 can be arranged...

Abstract
The invention discloses a manufacture method of a connecting rod of an air compressor and belongs to the technical field of low-pressure manufacture process. The method is used for solving the problems of conventional manufacture processes that production cost is relatively high, abrasion resistance is relatively poor, and use requirements of new-structure aluminum connecting rod without a bearing bush and a shaft sleeve are hard to meet. The method comprises the following steps: 1, firstly designing a reasonable pouring system and manufacturing a low-pressure casting sand mold according to the connecting rod of the air compressor; 2, smelting alloy b adopting a melt processing technique; 3, carrying out low-pressure casting on the alloy to obtain a required connecting rod. According to the invention, the original production technique of the connecting rod can be improved, a technique method for the aluminum alloy connecting rod simple in technique and light in weight and high in strength can be provided, thus having great economic significance.
Description
technical field [0001] The invention belongs to the technical field of low-pressure casting technology, and in particular relates to a method for manufacturing an air compressor connecting rod. Background technique [0002] As the main moving part of the energy conversion of the air compressor, the connecting rod is subjected to high periodic impact force, inertial force and bending force, which requires that the connecting rod not only have sufficient strength and stiffness, but also have as small a force as possible. Quality to meet the requirements of lightweight design and air compressor performance. [0003] The traditional connecting rod manufacturing process mostly uses malleable cast iron or nodular cast iron, and the quality of the produced connecting rod is relatively large, so that the movement noise, swing and rigidity of the main components of the air compressor or engine (such as pistons, crankshafts, connecting rods, etc.) Fuel consumption and mechanical stre...
