Description
Technical Field
The utility model belongs to airborne vehicle technique and combined material technique relate to an instrument that is used for heat distribution to test.
Background
In the prior art, a glass cloth laminated layer is used as a tool for heat distribution test to insulate a thermocouple of a tool. In the process of manufacturing and laminating layers, the glass cloth is not easy to manufacture and fix due to the fact that the number of the laminated layers of the glass cloth is large and the glass cloth is easy to slide, the mutual contact area of each layer of the glass cloth is not uniform, the area of the effective heat insulation area of the laminated layers of the glass cloth is smaller than the effective heat insulation area required by testing, and the thermocouple is difficult to fix in the middle of the effective heat insulation area.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the problem of the instrument of heat distribution test is not hard up easily, is difficult for fixed thermocouple is solved.
The technical scheme of the utility model is that:
in a first aspect, a tool for thermal distribution testing is provided, comprising:
a glass fiber block with a hole and a thermocouple are arranged; the thermocouple is inserted into the opening, and the height of the opening arranged on the glass fiber block is determined by the heat insulation efficiency of the part; the glass fiber block is arranged at the leeward part of the tool; forming a part on a tool; and outputting the detection result of the thermocouple to the hot-pressing irrigation monitoring platform.
Further, the opening is provided at a depth of the glass fiber block to be half of a length of the glass fiber block so that the thermocouple is located at a central position of a cross section of the glass fiber block.
Furthermore, the glass fiber block is bonded on the surface of the leeward part of the tool through a high-temperature-resistant adhesive tape.
Further, the glass fiber block is a cuboid, wherein a pair of opposite faces are square.
Further, the dimensions of the opposing faces are 100X 100 mm.
Furthermore, the installation position of the glass fiber block ensures that the time for the thermocouple in the glass fiber block installed at the installation position to reach the curing temperature is 5-30min later than the time for the lagging thermocouple in the test part to reach the curing temperature.
The utility model has the advantages that:
1. the utility model discloses adjustment to thermal-insulated effect only needs to go on through the height of thermocouple installation trompil position, can accomplish in 1 minute. Compared with the operation that the glass cloth is laminated by more than 50 layers and needs to be cut, folded and fixed, the efficiency and the use effect are greatly improved.
2. The density of the glass fiber block is greatly reduced compared with that of the metal block, the adhesive tape can be used for being quickly fixed on the tool in the testing stage, and when the mounting position is changed according to testing requirements, the adhesive tape is removed, so that the glass fiber block can be quickly taken down and fixed again. The method does not need to be fixed on a tool only by welding or screw connection due to heavy weight like a metal block, and cannot meet the requirement that the position needs to be replaced for many times in the test stage when the specific position cannot be determined in the test stage.

Detailed Description
The present invention will be described in further detail below.
Before the composite material part is manufactured, the forming tool 1 and the part need to be subjected to heat distribution test. And finding out the region with the fastest temperature rise and temperature drop (called part leading thermocouple) and the region with the slowest temperature rise and temperature drop (called part lagging thermocouple) in the part during the heating forming through testing. Meanwhile, areas (a tool 1 leading couple and a tool 1 lagging couple) which can be matched with the thermocouple are found out on the tool 1 arrangement thermocouple in the same process, and the heating rate, the curing temperature, the curing time and the cooling speed of the part are monitored only by using the tool 1 leading couple and the tool 1 lagging couple when the formal part is cured and molded in the future, so that the requirement of the process can be met.
Purpose and necessity of thermal profile test:
1. the region where the part temperature rises/falls the fastest (part leading couple) and the region where the part temperature rises/falls the slowest (part lagging couple) are both inside the composite part (i.e., within the cut line of the part). If the part thermocouple is used for monitoring, the integrity of the part is damaged, and the manufacturing requirement of the part cannot be met.
2. The matching requirements of the lead/lag thermocouple and the part lead/lag thermocouple of the tool 1 are as follows: the leading couple of the tool 1 is slower than the leading couple block of the part, and the lagging couple of the tool 1 is slower than the lagging couple of the part. The detection range of the tool 1 thermocouple completely encompasses the range of the part thermocouple, and therefore it is completely feasible to use the tool 1 thermocouple instead of the part thermocouple.
3. The thermocouple of the tool 1 is positioned on the tool 1, the integrity of the part cannot be damaged outside the part (namely outside the cutting line of the part), and the task of monitoring necessary parameters of the part such as temperature rising/reducing rate, curing temperature, curing time and the like can be completed.
As shown in fig. 1, the installation method of the present invention is: 1 inserting a thermocouple 3 into a glass fiber block 2 (glass fiber block) 1; 2 the glass fiber block 2 is fixed on the tool 1.
