Embodiment 1

[0038] Example 1: The fine sand-like raw material is only new silica sand

[0039] The configuration and mixing method of the fine sandy raw material used for the production of said process vase are as follows:

[0040] In the first step, enter the new sand standard sand volume of 240kg on the control panel of the additive manufacturing equipment, and enter the configuration volume of the curing agent 2.52L;

[0041] The second step is to read the actual amount of silica sand in the sand-adding funnel. If the actual amount of silica sand in the sand-adding funnel is not less than the minimum amount of sand, then do not add new silica sand to the sand-adding funnel. If the amount of silica sand in the sand-adding funnel If the actual amount of sand is less than the minimum amount of sand, execute the "third step";

[0042] The third step is to detect the state of the sand outlet butterfly valve of the sand adding funnel. If the sand outlet butterfly valve of the sand adding fu...

Embodiment 2

[0057] Embodiment two: the raw material of fine sand is new silica sand and old silica sand

[0058] In this embodiment, the sand adding funnel is divided into a new sand adding sand funnel and an old sand adding sand funnel, and the sand outlets of both are connected with the sand mixing tank, and the ratio of new silica sand to old silica sand is 7:3, according to If the total silica sand required is 240kg, then the new silica sand is 168kg, the old silica sand is 72kg, and only the new sand needs to be equipped with a curing agent, so the required curing agent is 1.76L.

[0059] In the first step, input the standard sand volume of new silica sand 168kg, the standard sand volume of old silica sand 72lg on the control panel of the additive manufacturing equipment, and input the configuration volume of curing agent 1.76L;

[0060] The second step is to read the actual amount of silica sand in the new sand-adding funnel. If the actual amount of silica sand in the new-sand-addin...

Abstract

The invention provides a preparation method of a fine-sand-shaped raw material, and aims to overcome the defects of unstable preparation and mixing as well as poor uniformity in the fine-sand raw material for additive manufacturing equipment. According to the preparation method of the fine-sand-shaped raw material, a butterfly valve type switch component is arranged on a hardware component, and hardware actions are controlled through software in order to realize accurate control of the adding amount. In the preparation method of the fine-sand-shaped raw material, a reasonable stirring structure is provided, and the stirring time is controlled, so that the mixing uniformity is realized, thereby ensuring the accuracy of raw material preparation and the mixing uniformity, and guaranteeing theproduction of qualified products.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a method for configuring and mixing fine sand-like raw materials for additive manufacturing equipment. Background technique [0002] Additive manufacturing equipment using fine sand or powder materials as raw materials has high requirements for the configuration and uniformity of raw materials. In order to realize the production automation of additive manufacturing equipment and improve product production efficiency, it is necessary to prepare raw materials in advance, and to ensure the qualification and stability of raw materials. Problems such as insufficient product strength and uneven surface caused by the unstable amount of raw material configuration and mixing uniformity in the current production process need to be solved urgently. Contents of the invention [0003] The invention overcomes the problem of unstable configuration and mixing uniformity of fine...
