Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-low temperature impact box, in particular to a composite impact box with a buffer box for flat temperature. BACKGROUND

[0002] The high-low temperature impact box is a necessary testing equipment for metal, plastic, rubber, electronic and other material industries, which is used for testing the tolerance of material structure or composite material under the continuous environment of extremely high temperature and extremely low temperature in an instant, so as to detect the chemical changes or physical damage caused by thermal expansion and cold contraction in the shortest time. The high-low temperature impact box is divided into two-compartment and three-compartment types, which are different in test method and internal structure. The product meets the requirements of GB / T2423.1-2008 test A, GB / T2423.2-2008 test B, GB-T10592-2008, GJB150.3-198, GJB360A-96 method 107 temperature impact test.

[0003] During the operation of the two-compartment basket impact box, the high-temperature box and the low-temperature box are in relatively independent spaces due to good sealing isolation. When the basket moves, the air pressure in the high-temperature box and the low-temperature box changes rapidly, thereby driving the internal gas to flow. In order to keep the internal air pressure equal to the atmospheric pressure, a hole is usually opened in each high-low temperature box to communicate with the atmosphere. However, in actual operation, the high frequency of basket operation causes serious temperature loss, and in the static state, the temperature will also be lost from the hole communicating with the atmosphere, thereby reducing the temperature impact times. SUMMARY

[0004] The present application aims at the defects and deficiencies of the prior art, and provides a composite impact box with a buffer box for flat temperature.

[0005] The composite impact box with a buffer box for flat temperature comprises a buffer box installed on the impact box, and the buffer box is connected with the high-temperature box and the low-temperature box of the impact box through a communication mechanism.

[0006] Further, the communication mechanism comprises a U-shaped pipe one and a U-shaped pipe two installed on one side of the impact box; the U-shaped pipe one is connected with the high-temperature box and the buffer box respectively; and the U-shaped pipe two is connected with the low-temperature box and the buffer box respectively.

[0007] Further, the U-shaped pipe one and the U-shaped pipe two are stainless steel pipes.

[0008] Further, a sealing ring one is arranged at the connection between the U-shaped pipe one and the high-temperature box and the buffer box, so as to ensure the air tightness of the connection between the U-shaped pipe one and the high-temperature box and the buffer box.

[0009] Further, a sealing ring two is arranged at the connection between the U-shaped pipe two and the low-temperature box and the buffer gas box.

[0010] Further, an electromagnetic valve one and an electromagnetic valve two are arranged on the U-shaped pipe one and the U-shaped pipe two respectively.

[0011] The compound impact box with a buffer gas box and beneficial to flat temperature has the advantages that a buffer gas box is added in the running system of the impact box, the high-temperature box and the low-temperature box are connected and form sealed spaces when the basket runs, and the pressure and the gas change during running are used to quickly increase or decrease the pressure and the gas in each box, so that the temperature loss is reduced. In the static state, the gas is in a relative vacuum state and will not flow randomly to cause temperature loss, so that the impact frequency is increased. BRIEF DESCRIPTION OF DRAWINGS

[0018] The present application will be described in detail below in combination with the drawings and specific embodiments, and the illustrative embodiments and the description are only used to explain the present application, but do not limit the present application.

[0019] As shown in the drawings, Figure 1 the compound impact box with a buffer gas box and beneficial to flat temperature in the present embodiment includes a buffer gas box 3 installed on the impact box, and the buffer gas box 3 is connected with the high-temperature box 1 and the low-temperature box 2 of the impact box through a communication mechanism.

[0020] Furthermore, the communication mechanism includes a U-shaped tube 4 and a U-shaped tube 5 installed on one side of the impact chamber; the U-shaped tube 4 is connected to the high-temperature chamber 1 and the slow-release chamber 3 respectively; the U-shaped tube 5 is connected to the low-temperature chamber 2 and the slow-release chamber 3 respectively.

[0021] Furthermore, the U-shaped tube 4 and the U-shaped tube 5 are stainless steel conduits.

[0022] Furthermore, a sealing ring is provided at the connection between the U-shaped tube 4 and the high-temperature chamber 1 and the buffer chamber 3 to ensure the airtightness of the connection between the U-shaped tube 4 and the high-temperature chamber 1 and the buffer chamber 3.

[0023] Furthermore, a sealing ring is provided at the connection between the U-shaped tube 2 5 and the low-temperature chamber 2 and the venting chamber 3.

[0024] Furthermore, solenoid valve 11 and solenoid valve 20 are respectively provided on the U-tube 4 and U-tube 5.

[0025] The working principle of this design is as follows:

[0026] like Figure 1 As shown in the diagram, in this design, a traditional impact chamber typically consists of a high-temperature chamber 1 and a low-temperature chamber 2. The bottom surface of the high-temperature chamber 1 has an upper opening 6, and the top surface of the low-temperature chamber 2 has a lower opening 7. The upper opening 6, the lower opening 7, and the inner cavities of the high-temperature chamber 1 and the low-temperature chamber 2 form a basket channel 8. A guide rail is installed inside the basket channel to facilitate the movement of the basket 9. A motor is used to control the basket 9 to move up and down on the guide rail, thereby achieving high and low temperature impact on the product to be tested on the basket.

[0027] During operation, the movement of the basket causes rapid changes in air pressure within the high-temperature chamber 1 and the low-temperature chamber 2, leading to airflow within each chamber. Traditional high- and low-temperature impact chambers typically have a vent connecting them to the outside atmosphere to maintain equal internal air pressure. However, this direct connection results in heat loss. To address these issues, our company employs a buffer chamber and a connecting mechanism. This buffer chamber and connecting mechanism allow for pressure regulation within the high-temperature and low-temperature chambers during the basket's lifting and lowering motion.

[0028] The design is to open holes on the high-temperature box and the low-temperature box of the traditional impact box, and then increase a buffer gas box. The buffer gas box is generally in the shape of a rectangle, and the size of the buffer gas box can be determined according to the size of the impact box. Then, the high-temperature box and the low-temperature box are connected with the buffer gas box by stainless steel pipes. The high-temperature box is connected with the buffer gas box by a U-shaped pipe 1, and the low-temperature box is connected with the buffer gas box by a U-shaped pipe 2. The U-shaped pipe 1 and the U-shaped pipe 2 form a communication mechanism. A sealing ring 1 is arranged at the connection between the U-shaped pipe 1 and the high-temperature box 1 and the buffer gas box 3, so as to further ensure the air tightness of the connection between the U-shaped pipe 1 and the high-temperature box 1 and the buffer gas box 3. A sealing ring 2 is arranged at the connection between the U-shaped pipe 2 and the low-temperature box 2 and the buffer gas box 3, so as to further ensure the air tightness of the connection between the U-shaped pipe 2 and the low-temperature box 2 and the buffer gas box 3.

[0029] The U-shaped pipe 1 and the U-shaped pipe 2 in the design are made of stainless steel pipes, so they can be welded with the high-temperature box and the low-temperature box made of metal materials. The U-shaped pipe 1 and the U-shaped pipe 2 are welded between the buffer gas box and the high-temperature box and the low-temperature box, so as to ensure that the parts are tightly welded and do not leak air. Moreover, the cost of modifying the traditional high-low temperature impact box is relatively small, and the cost can be reduced and controlled, so as to ensure that the performance is improved while the cost performance is ensured.

[0030] In the design, when the basket rises, the gas flow direction between the high-temperature box 1, the U-shaped pipe 1, the buffer gas box 3, the U-shaped pipe 2 and the low-temperature box 2 is as shown in FIG. 1. Figure 2 When the basket rises, the gas flow rises, the gas flow is guided from the U-shaped pipe 1 to the buffer gas box 3, and then to the U-shaped pipe 2, and then to the low-temperature box 2, so as to ensure the gas flow and reduce the loss of temperature.

[0031] In the design, when the basket falls, the gas flow direction between the low-temperature box 2, the U-shaped pipe 2, the buffer gas box 3, the U-shaped pipe 1 and the high-temperature box 1 is as shown in FIG. 2. Figure 3 When the basket falls, the gas flow is pressed downward from the low-temperature box 2 to the buffer gas box 3 through the U-shaped pipe 2, and then to the high-temperature box 1 through the U-shaped pipe 1, so as to ensure the gas flow and reduce the loss of temperature.

[0032] In the design, electromagnetic valves 1 and 2 can be arranged on the U-shaped pipe 1 and the U-shaped pipe 2 respectively, so as to realize conduction and cut-off.

[0033] In the design, since the high-temperature box, the low-temperature box and the buffer gas box have good air tightness, in the static state, the gas is in a relative vacuum state, and will not flow randomly to cause temperature loss, so as to increase the number of impacts.

[0034] The above description is only the preferred embodiment of the present application, so equivalent changes or modifications made according to the features and principles described in the patent application scope of the present application are included in the patent application scope of the present application.
