Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a testing device for the production of rubber seals. Background Technology

[0002] Testing equipment is a specialized device used to simulate actual working conditions and test product performance. It typically includes modules for sealing performance testing, mechanical performance testing, and environmental resistance testing. Through automated or semi-automated operation, it ensures that the dimensional accuracy, elastic recovery rate, durability, and other indicators of the seals meet industry standards, thereby guaranteeing product quality and optimizing production processes.

[0003] Existing testing equipment for rubber seal production may have problems such as: inability to flexibly adjust the compression state of the seal, making it difficult to meet different testing needs; inability to collect and monitor water pressure data at the seal in real time, failing to provide comprehensive and accurate data support for quality inspection to determine whether there is leakage; and inability to provide testing environments with different temperatures, resulting in a limited testing range and inability to more accurately test the quality of rubber seals. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a testing device for rubber seal production, thereby solving the problem mentioned in the background art of limited testing range and inability to more accurately test the quality of rubber seals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for rubber seal production, comprising:

[0006] A test chamber, wherein a cylinder is installed on the lower surface of the top plate of the test chamber, a sealing plate is installed on the output end of the cylinder, and a test seat is installed in the middle of the inner cavity of the test chamber;

[0007] A water pump is installed on the upper surface of the partition plate inside the test chamber. The outlet of the water pump is equipped with a delivery pipe, which is connected to the interior of the sealing plate. A pressure sensor is installed on the upper surface of the sealing plate, and a data acquisition module is installed on the upper surface of the pressure sensor.

[0008] An air heater is installed at the air inlet of the test chamber. An air supply pipe is installed at the air outlet of the air heater, and a heating frame is installed at the air outlet of the air supply pipe.

[0009] Preferably, the heating frame is installed on the upper surface of the inner cavity partition of the test chamber. The heating frame has a U-shaped design and is located on the outer periphery of the test seat, so that the heating frame can more effectively conduct high-temperature tests on the rubber seals.

[0010] Preferably, the surface of the test chamber is provided with an air outlet groove, and the upper surface of the inner cavity partition of the test chamber is provided with a recovery groove. The air outlet groove allows the gas inside the test chamber to circulate, and the recovery groove can recover the water flowing out during the test.

[0011] Preferably, a water storage chamber is provided in the lower part of the inner cavity of the test box, and a water pump inlet is equipped with a water pumping pipe. When the water pump is started, water is pumped out of the water storage chamber through the water pumping pipe.

[0012] Preferably, a water inlet seat is installed at the bottom of the inner cavity of the water storage chamber, and the recess of the water inlet seat is located at the water inlet of the water pumping pipe, which facilitates the water pumping pipe to draw out water.

[0013] Preferably, the inner wall of the heating frame is evenly provided with air outlets, and the air outlets are on the same horizontal line as the upper surface of the test seat, so that the heating frame can more effectively conduct high-temperature tests on the rubber seals.

[0014] Compared with the prior art, this utility model provides a testing device for the production of rubber seals, which has the following advantages:

[0015] This testing device for rubber seal production features a cylinder that can lift and lower the sealing plate, allowing for flexible adjustment of the fit between the sealing plate and the test seat. This allows for the compression of the rubber seal to meet various testing requirements. A water pump is located on the upper surface of the partition inside the test chamber, with its outlet connected to the inside of the sealing plate via a delivery pipe. This pump delivers water to the sealing plate, and, in conjunction with a pressure sensor and data acquisition module, can collect and monitor the water pressure data at the sealing plate in real time, monitoring the pressure decay curve. If the pressure drop exceeds a threshold, it is determined to be a leak, providing comprehensive and accurate data support and judgment criteria for the quality inspection of rubber seals.

[0016] The added air heater heats the air entering the test chamber and delivers the hot air to the heating frame through the air supply pipe, providing different temperature environments for testing and expanding the testing range of the test device. In conjunction with the sealing plate, it can more accurately test the quality of rubber seals. Attached Figure Description
