Embodiment 1

[0027] see figure 1 As shown, a multi-point temperature detection and cooling control system for a liquid forging die, including a temperature detection sensor, a programmable logic controller, an electric regulating valve, and an alarm module.

[0028] The temperature detection sensor is installed on a key part of the liquid forging die that needs to control the cooling temperature, and is used to detect the temperature change of the part in real time, and send the detected temperature information to the programmable logic controller. And the key parts of the liquid forging die that need to control the cooling temperature are respectively provided with cooling water channels, and the conduction state of each water channel is controlled by an electric control valve, which is connected to the programmable logic controller. When the programmable logic control If the controller controls the electric control valve to switch from the cut-off state to the conduction state, the flow ...

Embodiment 2

[0036]On the basis of Embodiment 1, further, the computer is connected to the cloud platform through the network, and the data of the S7-300 can be uploaded to the cloud platform, and the cloud platform is connected to mobile terminals such as mobile phones or industrial tablets through the network, thereby realizing mobile sharing of data.

Embodiment 3

[0038] On the basis of Embodiment 1, further, the temperature detection and control system based on wireless communication transmission also includes a remote I / O module ET200, ET200 is connected to the Profibus-DP bus through the interface module IM153-1, and the remote The I / O is transmitted to the host through the communication line, which saves a lot of signal cables, makes the structure clear and easy to maintain.

Abstract

The invention discloses a multi-point temperature detecting and cooling control system of a liquid die forging die. The multi-point temperature detecting and cooling control system comprises a temperature detecting sensor, a programmable logic controller, electric control valves and an alarm module, the temperature detecting sensor is mounted on the key part, which the cooling temperature needs tobe controlled, of the liquid die forging die, and used for detecting temperature change of the part in real time, cooling water channels are respectively arranged on the key part, which the cooling temperature needs to be controlled, of the liquid die forging die, the conduction state of each water channel is controlled by one electric control valve, and the conduction state and off state of theelectric control valve are controlled by the programmable logic controller. According to the multi-point temperature detecting and cooling control system, temperature situations of all points of the liquid die forging die can be monitored in real time, when abnormity occurs, alarming is conducted in time, feedback and control are automatically achieved, the serial number of a high temperature position can be obtained according to feedback of the abnormal temperature sensor, and the temperature and high temperature position serial number are sent to an upper computer to be displayed and stored.

Description

technical field [0001] The invention relates to the technical field of liquid die forging control, in particular to a multi-point temperature detection and cooling control system of a liquid die forging die. Background technique [0002] The liquid die forging process uses a liquid forging machine to directly pressurize the molten metal poured into the mold cavity, so that the molten metal is rheologically filled, crystallized and rheologically fed under the action of pressure, accompanied by a small amount of plastic deformation. Appropriate solidification time and cavity temperature are beneficial to reduce or eliminate defects such as internal shrinkage cavity, shrinkage porosity, porosity, and chemical composition deviation, so as to obtain blanks or parts whose mechanical properties are close to pure forging forgings but better than pure castings. [0003] At present, the liquid forging forming process preliminarily realizes the off-line temperature control through the ...
