[0026] When the device is used for high and low temperature impact tests, after placing the object to be tested inside the placement tube 9, the rotation of the bolt 10 can be controlled. Through the limiting activity of the clamping plate 11, the rotation of the bolt 10 can be controlled to drive the clamping plate 11 to clamp and position the test object. Subsequently, the cylinder 4 can drive the telescopic activity of the pneumatic push rod 5, thereby driving the punch head 6 to perform a punching test on the test object positioned in the placement tube 9. The interior of the placement tube 9 can be provided with an electric heating plate 12, which surrounds and wraps the test object inside the placement tube 9. After being powered on, it can heat the outside of the test object, and then the temperature of the test object can be controlled. The temperature can be adjusted by controlling the temperature so that the punching test can be performed under different high and low temperature conditions.

[0027] A movable door 13 is movably installed on the front of the test box 1, and glass plates 14 are embedded and installed on both sides of the test box 1;

[0036] The arc-shaped baffle 19 can play a role of obstruction, thereby avoiding the problem of breakage and sputtering during the punching test on the top of the placement tube 9, and plays a certain role of obstruction and protection for the interior of the device.

[0037] Working principle:

[0038] When the device is in use, it can place the object to be subjected to the stamping test inside the placing tube 9, and then clamp and fix the test object through the clamping structure inside the placing tube 9, thereby ensuring its stability during the test. The electric heating plate 12 inside the placing tube 9 can be used to regulate the temperature of the test object, and the stamping structure inside the device can be used to impact the test object, so that the device can perform high and low temperature impact tests under its temperature regulation. The temperature control structure that fits the test object can increase the convenience of the device in performing high and low temperature impact work.
