Description
Technical field
The present invention relates to a kind of detection device of sheet metal, particularly a kind of wet-hot aging performance based on sheet metal is certainly
Motion detection device.
Background technology
Resistance and fingerprint resistance continuously dip coat zine plate is the product that resistance and fingerprint resistance processing is carried out to continuous hot galvanizing plate surface, is mainly used for making
Make the products such as computer housing, server and household electrical appliances postnotum.Surface wet-hot aging performance is to weigh resistance and fingerprint resistance continuously dip coat zine plate matter
Measure one of good and bad leading indicator, it is therefore an objective to detect when coil of strip is transported and stored in hygrothermal environment whether surface corrosion occurs.
At present, the conventional method of detection resistance and fingerprint resistance continuously dip coat zine plate wet-hot aging performance is：By sheet metal list to be detected
Piece or lamination are placed in climatic chamber, after placing a period of time under certain temperature and humidity, estimate or use color difference meter
Whether detection surface of steel plate blacks or generates white rust.
Be applied with certain tension during coil of strip batches in Continuous Hot Dip Galvanizing Line, thus transport after coiled and
During storage, steel plate is by two kinds of stress of tensile stress and compression.And suffered stress particularly tensile stress can accelerate steel
Corrosion of the plate under hygrothermal environment.Since moisture-proof heat detecting device or method, do not consider that sheet metal is being transported and stored at present
When suffered stress state, practical problem cannot be reflected by testing hot resistance test data.If some sheet metals are in wet-heat resisting
It does not go wrong in performance detection, still, the phenomenon that plate face corrosion then occurs during actual shipment and storage.
Disclosed in 7 days Mays in 2014 application No. is 201310753357.2 Chinese invention patent application, disclose one kind
Plank wet-hot aging performance detection fixture, the detection fixture include stent, the clamping plate with locking nut and clamping screw and
8 springs of stretching.
Disclosed in September in 2014 29 days application No. is201410512643.4Chinese invention patent, innovation and creation
Entitled " a kind of sheet metal wet-hot aging performance detection fixture ", including stent, the first bench vice, the second bench vice and with spring draw
Power meter, the first bench vice and the second bench vice include clamping plate and several pieces of spacer blocks that can be slid back and forth.
Above-mentioned patent application can apply certain tensile stress to sheet metal in test really, however it remains
Following deficiency：
1. the tensile stress that sheet metal is born is too small or too big, the test data for testing wet-heat resisting also still cannot
Reflect practical problem.
1）When the tensile stress that sheet metal is born is too small, sheet metal influenced by stress it is small, deformation it is small, damp and hot
Under environment, extent of corrosion is low, and being susceptible to sheet metal, there is no problem in wet-hot aging performance detection, and judgement is qualified, but in reality
Border is transported and storage the phenomenon that plate face corrosion occurs again in the process.
2）When the tensile stress that sheet metal is born is too big, the influence of sheet metal stress is big, and deformation is big, in damp and hot ring
Extent of corrosion under border is fast, is susceptible to that sheet metal is bad in wet-hot aging performance detection, and judgement is unqualified, but in practical fortune
The phenomenon that being not in plate face corrosion namely wrong report during defeated and storage.In order to improve the qualification rate of detection judgement, factory
Family needs to do over again or improve technological level again, thus can increase production or manufacture the input of cost.
2. structure design is unreasonable, using being inconvenient：The surrounding of sheet metal is both provided with locking nut and locking screw
Bolt when placing every time, is both needed to all unscrew all locking nut and clamping screw, then remove upper laminated plank, ability
Sheet metal is placed.Then, upper laminated plank is placed on sheet metal to be detected again, and will need to each locked
Nut and clamping screw are fixed, and follow-up operation every time is both needed to repeat aforesaid operations.Whole operation is cumbersome, and labor intensity is big,
Using being inconvenient.
3. the pressing force and drawing force that in test, same sheet metal is born are uneven, it is such as clamped plate or bench vice
The position of clamping is subjected only to pressing force, is not clamped the position that plate or bench vice clamp and is then subjected only to drawing force namely same metal
The same position of plank cannot i.e. bear pressing force bears drawing force again, therefore is unable to stress when reacting metal plank stacks placement
State, therefore the practical corrosion degree that the test data of tested wet-heat resisting will be unable to reacting metal plank.
Invention content
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide one kind is easy to operate, oneself
Dynamicization degree is high, test wet-heat resisting the practical corrosion degree of test data energy reacting metal plank based on the resistance to of sheet metal
Hygrothermal Properties automatic detection device.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of wet-hot aging performance automatic detection device based on sheet metal, including cylindrical tube, heating airbag, PLC
