Precoated sand sample maker with intelligent temperature control

Abstract

The invention discloses a precoated sand sample maker with intelligent temperature control, comprising a base, a heater, a sample core box, an upper template, a lower template, and a digital temperature control device; the heater, the sample core box, the upper template, the lower template, and the digital temperature control device are arranged on the base; the base is further provided with a module used for making a precoated sand sample and an eccentric wheel used for pressing the module; a handle for facilitating its rotation is arranged on the eccentric wheel, and a straight slot for leaving position for a handle in rotation is arranged on the upper template; the upper part of the straight slot is provided with a fixing block for fixing the handle after downwards pushing. The precoated sand sample maker provided by the invention comprises the base, the heater, the sample core box, the upper template, the lower template, the digital temperature control device and other parts; the prepared sample has accurate dimension, upper and lower heating modules can be independently controlled; the sample is uniformly heated, thus stability of intensity value of every batch of sample is guaranteed, the intelligent control degree and the sampling efficiency are high; the precoated sand sample maker is provided with digital timing and alarm prompt; moreover, the sample maker is simple in operation and convenient to maintain.

Description

Technical field [0001] The invention relates to a coated sand sample preparation device, in particular to an intelligent temperature control coated sand sample preparation machine. Background technique [0002] Coated sand sample making machine is a kind of equipment used to quickly and manually make standard samples of coated sand bending and tensile, which is widely used in scientific research, production, teaching and other fields. At present, the coated sand prototype machine on the market mainly includes a base, the base is fixed with a lower template, the lower template is hinged with an upper template, and the upper and lower templates can also be placed between the upper and lower templates to make tensile strength or bending strength For the mold of the sample, the lower template is also provided with an eccentric wheel for pressing the mold, and the base is also provided with a control panel. In order to facilitate the removal of the sample, the general mold is divided ...

AI Technical Summary

Problems solved by technology

At present, the coated sand prototyping machines on the market mainly include a machine base on which a lower formwork is fixed, and an upper formwork is hinged on the lower formwork, and the upper and lower formworks can also be placed between the upper and lower formworks to make tensile strength or bending strength. For the mold of the sample, the lower template is also provided with an eccentric wheel for pressing the mold, and the base is also provided with a control panel. In order to facilitate the removal of the sample, the general mold is split. Place the mold on the lower template, put another piece in alignment, then turn the handle of the eccentric wheel to make the eccentric wheel press the mold, then put the sample sand and close the upper template for sample preparation. There is no fixing mechanism for the eccentric wheel in the above process , due to the small size of the sample making machine, it is not very stable to place on the desktop platform. During the sample making process, if you accidentally touch the testing machine or trip over the wires, it is easy to shake the sample making machine. At this time, the eccentric wheel is easy to rotate and the mold is not fixed stably. ; and the existing coated sand sample making machine has a low degree of intelligent control, and the sample preparation efficiency is low
