Abstract
The utility model relates to a with give first place to material preparation of sheet metal, require the airtight testing arrangement of sealed box class product, including healthy tendency potential source, manometer, pressure sensor, control system and high accuracy flowmeter, still including parallelly connected malleation system of aerifing and the negative pressure suction system that sets up, the malleation system of aerifing includes valve V1 -2, V1 -4, V2 -2 and V2 -4, the negative pressure suction system includes valve V1 -1, V1 -3, V2 -1 and V2 -3, control system control respectively in the malleation system of aerifing with the negative pressure suction system on valve and atmospheric pressure source. To the trade control of high -pressure spiral fan, satisfy the condition of malleation and negative pressure. Airtight testing arrangement area is little for the panel beating box, can promote portable operation alone, equipment control accuracy deviation is less than 5%, adopt controller automatic control, online switching test technology is automized, the level of IT application is high, satisfies the production demand of the quick test of product batch ization.
Description
Technical field
The utility model relates to a kind of malleation, negative-pressure testing device, especially relates to one with thin plate for main material makes, the airtight test device of the casing series products of requirement sealing.
Background technology
Panel beating is a kind of comprehensive cold machining process for sheet metal (usually at below 3mm), comprises cutting, rushing/cut/compound, folding, welding, riveted joint, splicing, shaping (as body of a motor car, rail transportation vehicle-mounted air-conditioning) etc.Its significant feature is exactly Same Part consistency of thickness.The product processed by sheet metal process is called sheet metal component.The sheet metal component of different industries indication is generally different, is used for address during assembly.Sheet metal component bubble-tight testing experiment pressure is low, and precision prescribed is high, at present the main mode adopting cushion gas pressure tank balance, and the method has following drawback: surge tank manufactures complicated, and equipment is heavy, is not easy to mobile; Manually realize pressure and flow rate test by variable valve, product mass, the online requirement switched fast cannot be met; Control accuracy is low, only can reach 15%; Testing efficiency is low.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of thin plate seal case airtight test device.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical matters adopts: a kind of thin plate seal case airtight test device, comprise healthy tendency potential source, tensimeter, control system and high precision flow, also comprise the malleation gas charging system and negative inspiratory pressure system that are arranged in parallel, described malleation gas charging system comprises valve V1-2, V1-4, V2-2 and V2-4, described negative inspiratory pressure system comprises valve V1-1, V1-3, V2-1 and V2-3, described control system to control on malleation gas charging system and valve in negative inspiratory pressure system and pneumatic supply respectively, pneumatic supply is high pressure positive blower.
In a preferred embodiment of the present utility model, tensimeter front end is provided with miniature surge tank.
In a preferred embodiment of the present utility model, miniature surge tank is provided with high-precision digital-display pressure transducer.
The beneficial effects of the utility model are: sheet metal box body airtight test device floor area is little, and a people can promote, portable operation; Equipment control accuracy deviation is less than 5%; Adopt controller automatically to control, online switch test technique, robotization, the level of IT application are high, meet the Production requirement that product mass is tested fast.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of thin plate seal case airtight test device as shown in Figure 1, comprise healthy tendency potential source 1, tensimeter 2, control system and high precision flow 3, also comprise the malleation gas charging system and negative inspiratory pressure system that are arranged in parallel, malleation gas charging system comprises valve V1-2, V1-4, V2-2 and V2-4, negative inspiratory pressure system comprises valve V1-1, V1-3, V2-1 and V2-3, control system to control on malleation gas charging system and valve in negative inspiratory pressure system and pneumatic supply 1 respectively, and pneumatic supply 1 is high pressure positive blower; Tensimeter 2 front end is provided with miniature surge tank 4, is maintained by the stability of air pressure, improves tensimeter measuring accuracy; Miniature surge tank is provided with high-precision digital-display pressure transducer 5, facilitates the pressure condition in real-time monitoring surge tank.
This product solves the bubble-tight quick on-line testing of thin plate seal case (sheet metal box body), and adopt high pressure positive blower as healthy tendency potential source, variable frequency control air pressure and flow, high precision flow feedback closed loop controls stream pressure.Cardinal principle describes as follows: the mode first selecting tightness test: malleation or negative pressure, flow monitoring or pressure monitoring; During according to flow monitoring, after pressing start button, fan starting, control system opens valve V1-2, V1-4 and V2-2, V2-4 automatically simultaneously, and can realize malleation inflation, open valve V1-1, V1-3 and V2-1, V2-3 can realize negative inspiratory pressure; If selection pressure monitoring pattern, in Preset Time, after workpiece pressurize, whether leakage value is less than setting value, can judge that whether workpiece is qualified; If selection pressure monitoring pattern, when keeping continuing inflation or air-breathing, whether difference in flow meets setting requirement, can judge that whether workpiece is qualified.
Claims (3)
