Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of casting, and mainly relates to a method and system for recording the use frequency of casting outer chill. BACKGROUND

[0002] Chill is a metal object placed in the inside or surface of a casting mold to accelerate the cooling speed of a local part of a casting. As an important auxiliary tool in the casting production process, chill plays an important role in the quality control of castings. Chill is divided into inner chill and outer chill. Inner chill is placed in the mold cavity and can be integrated with the casting, so it can only be used once. Outer chill is placed on the surface of the mold during molding and does not melt with the casting during casting, so it can be reused.

[0003] Although outer chill can be reused multiple times, there is a limit to the number of times it can be used. This is because after repeated cycles of use, the surface of the outer chill will have small cracks, and as the number of uses increases, the cracks will also increase, resulting in a decrease in the chilling ability of the outer chill, which in turn leads to slag gas hole defects in the casting. Therefore, the number of times the outer chill is used has a direct impact on the quality of the casting, and effective recording and management of the number of times the outer chill is used is crucial.

[0004] However, the traditional method of recording the number of times the outer chill is used relies on manual counting or simple mechanical counting devices. This method is not only inefficient, but also has the problems of inaccurate recording, easy errors, and difficulty in tracing, which cannot meet the needs of modern industry for high precision and high efficiency. SUMMARY

[0005] The technical problem to be solved by the present application is how to efficiently and automatically record the number of times the casting outer chill is used.

[0006] To solve the above technical problems, the present application aims to provide a method and system for recording the number of times the casting outer chill is used, which can automatically and accurately record the number of times the outer chill is used.

[0007] The method comprises the steps of: connecting the outer chill with the deformation device in a detachable manner; connecting the deformation device with the counting device, triggering the counting device to record an outer chill use event when the deformation device is heated and deformed; connecting the counting device with the display device through wireless or wired connection, uploading the number of times the outer chill is recorded in the counting device to the display device for visual display.

[0008] The deformation device is made of shape memory alloy, and the length of low-temperature phase is less than that of high-temperature phase. Shape memory alloy refers to alloy materials with shape memory effect, which can maintain a certain shape at a certain temperature, and can restore to the original shape when heated to a certain temperature. The present application utilizes the characteristics of shape memory alloy to design a new method for recording the use frequency of casting external chill, to solve the problems in the prior art.

[0009] At room temperature, the deformation device maintains a short length that does not trigger the counting device. In use, the external chill is directly connected with the deformation device, and when the external chill is used in each casting process, the temperature of the external chill rises and the heat is conducted, and the temperature of the deformation device directly connected therewith also rises. The shape memory alloy is heated to deform and extend, which triggers the counting device to record a use event, and the current use frequency is displayed through the display device. After the casting process is completed, the external chill is removed, and the temperature of the deformation device gradually decreases to room temperature and shortens to the original length.

[0010] The counting device is used to store and manage the use frequency of the external chill, and includes a communication module and a storage module. The communication module can be connected with the display device through wireless or wired mode to realize data uploading. The storage module is used to save the use frequency of the external chill and set a threshold value of the use frequency, and when the use frequency of the external chill reaches or exceeds the threshold value, the communication module can send relevant warning information to the display device.

[0011] The display device is used to display the use frequency of the external chill, and includes a communication module, a warning module and a display module. The communication module is used to receive information sent from the counting device and is connected with the counting device through wireless or wired mode. The warning module is used to send a warning signal when the communication module receives the warning information sent from the counting device, to prompt the on-site operator to replace the external chill in time. The display module displays the current use frequency of the external chill in a visual manner, to facilitate the operator and the management personnel to check the use frequency of each external chill.

[0012] Preferably, the connection mode of the external chill and the deformation device is detachable riveting. In this way, when a certain external chill reaches the expected use frequency, the system can be disassembled and connected with another external chill for continuous use, to realize repeated use. In addition, since the shape memory alloy can be repeatedly used up to tens of thousands of times, the service life of the system is also long.

[0013] Preferably, the deformation device is in the shape of spring or thin rod. The shape memory alloy with excellent shape memory effect and mechanical properties is selected and prepared into the shape of spring or thin rod through precision machining.

[0014] Preferably, the phase change temperature of the shape change device is 100-200°C, which is only used as a reference, and the skilled in the art can reasonably select a suitable shape memory alloy material according to the actual situation to make the shape change device, so as to ensure that the shape change device can be extended enough to trigger the recording device to record the number of uses in a specific casting process.

[0015] Preferably, the display module includes a large screen display module or a mobile phone display module. The use frequency of each chiller can be displayed in the workshop through a visual large screen or viewed through a mobile phone, which is convenient for operators and managers to view.

[0016] Preferably, the display device further comprises a reporting module to generate a report on the number of uses in the form of an electronic document, which is convenient for managers to view and analyze historical data.

[0017] The application also provides a system for recording the number of uses of a casting chiller, which comprises a shape change device, a recording device and a display device; the chiller is detachably connected with the shape change device, the shape change device is connected with the recording device, and the recording device is connected with the display device through wireless or wired mode; the shape change device is made of shape memory alloy, and the length of the low-temperature phase is less than that of the high-temperature phase; the recording device comprises a communication module and a storage module, the communication module is connected with the display device through wireless or wired mode, and the storage module is provided with a threshold value of the number of uses of the chiller; the display device comprises a communication module, an alarm module and a display module, the communication module is used to receive information sent from the recording device, the alarm module is used to send an alarm signal when receiving an alarm information sent from the recording device, and the display module displays the number of uses of the current chiller in a visual manner.

[0018] The method and system for recording the number of uses of a casting chiller provided by the application can achieve the following technical effects: (1) automatic recording: without manual intervention, the defects of low efficiency and easy error of manual recording are overcome, and the automatic recording of the number of uses of the chiller is realized; (2) high accuracy: through the accurate deformation and recovery of the shape memory alloy, the recording of the number of uses of the chiller is accurate and error-free; (3) high reliability: the design is simple, and the system has good mechanical properties and stability, and maintains high performance in long-term use; (4) easy to read: the data is visualized, and the manager can check the number of uses of the chiller at any time; (5) strong traceability: the number of uses of the chiller can be stored and managed, which is convenient for subsequent tracing and analysis; (6) repeated use: when a chiller reaches the expected number of uses, the system can be easily connected to another new chiller, realizing multiple repeated use; (7) early warning function: a threshold value of the number of uses is set, and when the threshold value is reached or exceeded, an alarm information is sent to remind the operator to replace the chiller in time, thereby ensuring the quality of the casting.

Detailed Implementation

[0021] The method for recording the number of times an external chill is used in casting according to the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: Methods for recording the number of times the external chill has been used in casting include: like Figure 1 As shown, the external chill 001 is detachably connected to the deformation device 002; the deformation device 002 is connected to the counting device 003. When the deformation device undergoes heating deformation, the counting device 003 is triggered to record an external chill usage event; the counting device 003 is connected to the display device 004 wirelessly or via wired connection, and the number of external chill usages recorded in the counting device 003 is uploaded to the display device 004 for visualization.

[0023] like Figure 2 As shown, the deformation device 002 is made of shape memory alloy 201 and is spring-shaped or rod-shaped, with its low-temperature phase length being shorter than its high-temperature phase length. At room temperature, the deformation device 002 maintains a shorter length, which does not trigger the counting device 003. In use, the external chill is directly connected to the deformation device 002. During each casting process, when the external chill 001 is used, due to the temperature rise of the external chill 001 and heat conduction, the temperature of the deformation device 002 directly connected to it also rises. The shape memory alloy 201 deforms and extends due to the heat, which triggers the counting device 003 to record a usage event, and the current number of uses is displayed on the display device 004. After the casting process is completed, the external chill 001 is removed, and the temperature of the deformation device 002 gradually decreases to room temperature and shortens to its original length.

[0024] In this embodiment, the connection mode of the outer chill 001 and the deformation device 002 is detachable riveting.

Those skilled in the art can reasonably select a suitable shape memory alloy 201 according to the actual situation to ensure that the deformation device 002 can be extended enough to trigger the recording device 003 to start recording the use of the outer chill during a specific casting process.

[0026] As shown in Figure 3 , the recording device 003 is used to store and manage the number of uses of the outer chill, including a communication module 301 and a storage module 302. Among them, the communication module 301 can be connected with the display device 004 through wireless or wired mode to realize data uploading. The storage module 302 is used to save the number of uses of the outer chill 001 and set the threshold value of the number of uses. When the number of uses of the outer chill 001 reaches or exceeds the threshold value, the communication module 301 can send relevant warning information to the display device 004.

[0027] As shown in Figure 4 , the display device 004 is used to display the number of uses of the outer chill, including a communication module 401, a warning module 402, a display module 403 and a report module 404. Among them, the communication module 401 is used to receive the information sent from the recording device 003 and is connected with the recording device 003 through wireless or wired mode. The warning module 402 is used to send a warning signal when the communication module 401 receives the warning information sent by the recording device 003, prompting the on-site operator to replace the outer chill in time. The display module 403 displays the number of uses of the current outer chill in a visual way, including large screen display or mobile phone display. It can be displayed in the workshop through a visual large screen, or viewed through a mobile phone, which is convenient for operators and managers to view the number of uses of each piece of outer chill. The report module 404 generates a report on the number of uses of the outer chill 001 in the form of an electronic document, which is convenient for managers to view and analyze historical data.

[0030] The deformation device 002 is made of shape memory alloy 201, which is spring-shaped or thin rod-shaped.
