Description

Technical Field

[0001] The invention relates to the technical field of mica tape performance testing, in particular to a mica tape performance testing device. Background Art

[0002] The tensile and breaking strength performance test device of mica tape has an important role and purpose. Its role is to accurately measure the physical performance parameters such as tensile and breaking strength of mica tape, and provide a standardized platform for testing. On the one hand, its purpose is to ensure that product quality meets the standards, help manufacturers control quality and improve customer satisfaction. On the other hand, it can guide product development and optimization, help researchers select the best formula and process, and at the same time, ensure the safety and reliability of products in application, provide reliable data support for industries such as wires and cables, and ensure the normal operation and safe use of equipment.

[0003] However, in the prior art, the fracture and tensile strength tests of mica tapes are generally carried out at the same temperature in a horizontal state. However, if the winding of cylindrical parts and square plates cannot be simulated in the fracture and tensile strength tests of mica tapes, the test results will not be able to truly reflect the performance of the mica tape in actual application scenarios. Because in actual use, the mica tape is mostly wound around wires or square plates, the effects of different hardness, flexibility, surface roughness and materials on the winding of the mica tape cannot be detected. The effectiveness of the test results is low but the limitations are high. Considering the diversity of actual application environments, mica tapes will face different temperature conditions in the fields of wires and cables, motors and electrical appliances. If only tested at room temperature, its performance in an actual complex temperature environment cannot be reflected, which may bring safety hazards.

[0004] Therefore, a mica tape performance testing device is needed to solve the problem of low data validity and inability to perform testing under different temperature conditions due to the inability to simulate the actual situation of wire and plate winding during mica tape fracture and tensile strength testing.

The heater 2 is located on the side of the fixture away from the electric door 14. The heater 2 is electrically connected to the controller 12. Two insulating glass plates 13 are fixed through the top of the chassis 11.

[0035] In this embodiment, when it is necessary to test samples at different temperatures, it is necessary to use the controller 12 to make the heater 2 heat the temperature inside the chassis 11 after loading is completed. After reaching the target temperature, various tests are performed on the samples. The insulating glass allows the staff to implement the test throughout.

[0036] Furthermore, the transverse member includes a lead screw 91, which is fixed to the outer side of the output end of the motor 7, and the other end of the lead screw 91 is rotatably fixed to the top of the bottom wall of the chassis 11.

[0044] In this embodiment, before using the device, the staff prepares the mica tape sample required for the test (the sample length is 3 to 6 cm and the width is less than 8 cm), then opens the electric door 14 through the controller 12, and then places the prepared sample on the top of the placement block 43, and aligns the side of the placement block 43 close to the electric door 14 with the side of the sample close to the electric door 14, then controls the electric door 14 to close, and then starts the motor 7 through the controller 12, the motor 7 drives the lead screw 91 to rotate forward, the lead screw 91 drives the bottom plate 81 to move toward the side close to the electric door 14 through the connecting block 93, the limiting rod 92 provides support for the bottom plate 81 through the connecting block 93 while preventing the bottom plate 81 from shaking, the bottom plate 81 drives the longitudinal member, the base 85, the base 87 and the clamp to move toward the side close to the electric door 14, the bottom plate 81 drives the concave plate to move toward the side close to the electric door 14, and the inner sides of the two concave plates contact the bottom inclined surfaces of the two side plates 33 The two concave plates push the two side plates 33 to move toward the side close to the top of the chassis 11, and the two side plates 33 drive the movable cover 42 to move toward the side close to the top of the chassis 11. The two side plates 33 are squeezed by the two movable columns 32 to move along the inner sides of the two hollow columns 31 toward the side close to the top of the chassis 11. In this process, the four guide plates 69 will be moved toward the side away from the clamping plate 61 through the four pulling plates 68, thereby separating the fitted clamping plates 61. When the side of the concave plate close to the electric door 14 is fitted with the inner wall of the chassis 11, the movable cover 42 releases the closure of the top of the fixed seat 41, and the four pulling plates 68 move out from the outside of the four guide plates 69.

[0047] Working principle: The initial state is as follows Figure 1-Figure 9 As shown, before using the device, the staff prepares the mica tape sample required for the test (the sample length is 3 to 6 cm and the width is less than 8 cm), then opens the electric door 14 through the controller 12, and then places the prepared sample on the top of the placement block 43, and aligns the side of the placement block 43 close to the electric door 14 with the side of the sample close to the electric door 14, then controls the electric door 14 to close, and then starts the motor 7 through the controller 12, so that the movable cover 42 releases the closure of the top of the fixed seat 41, and the four clamping plates 61 clamp the sample;

[0048] During the horizontal tensile strength test, the staff starts the motor 7 through the controller 12.

When the pressure is applied on one side, the left side (such as Figure 7 The output end of the cylinder 1 (as shown) is contracted, and the output end of the cylinder 1 (62) stretches the sample on one side; when the pressure is applied on both sides, the output ends of the two cylinders 1 (62) are controlled to contract according to the specified working strength, and the output ends of the two cylinders 1 (62) stretch the sample on both sides. If the sample does not break when the specified strength is reached, it is qualified, and if it breaks, it is unqualified;

[0049] When testing horizontal breaking strength, the same procedure as horizontal tensile testing is followed. The sample is stretched and the data is recorded when the sample breaks.
