A hose clamping tool blasting test bench and test method

Abstract

The invention relates to a rubber hose clamping tool blasting test bench and a test method. Two rubber hose clamping devices are arranged on two guide rails, and the two ends of the rubber hose test piece respectively pass through the supporting cover plate and the supporting cover of the two rubber hose clamping devices in sequence. The middle hole of the front cylinder head is socketed with the hollow shaft, the motor drives the constant power plunger pump to supply oil to the system, and the ring buckle pressure formed by the gathering of eight modules presses the rubber hose test piece on the two hollow shafts; The system is supplied with air and filled with liquid. After the liquid is filled with the test piece hose, power off the two-position five-way solenoid valve II, close the air control needle valve, and the air-liquid pump starts to continuously pressurize the test piece hose until the test piece hose can no longer bear the pressure. Hold the high pressure and blast; start the switch, push the piston to move in the opposite direction, so that the eight modules buckled on the test piece rubber hose will be opened accordingly, and the test piece rubber hose will be removed, and one test is completed. The effect is: a series of processing such as stripping rubber of the rubber hose test piece and crimping the core joint is omitted, material waste is eliminated, and cost is saved; the overall operation is simple and convenient.

Description

technical field [0001] The invention relates to a hose clamping tool blasting test bench and a test method, which are used for blasting tests of steel wire braided (winding) hydraulic hoses and industrial hoses. Background technique [0002] At present, the existing test bench for testing the pressure-holding blasting performance of the rubber hose has a relatively simple test principle. Before testing the rubber hose of the specimen, the rubber hose needs to be processed again. Add a core and iron sheet, and then use a crimping machine to process it into a rubber hose assembly, which can then be installed on the blasting test bench for testing. The test installation needs to manually connect the joints at both ends, which wastes a certain amount of time before the test. When designing the tooling, the sealing form of the joints during the ultra-high pressure test must also be considered, and it is difficult to ensure that there is no leakage at the joints during the test. ...

The test installation needs to manually connect the joints at both ends, which wastes a certain amount of time before the test. When designing the tooling, the sealing form of the joint during the ultra-high pressure test should also be considered, and it is difficult to ensure that there is no leakage at the joint during the test.
