Abstract
The utility model discloses a steel plate sample bending device. The steel plate sample bending device aims to solve the problems that an existing steel plate sample bending is not standardized, and equipment is complicated. The steel plate sample bending device comprises a left groove sample clamp and a right groove sample clamp. A bending shaft penetrates through baffles on the two sides of the groove sample clamps and the baffles are hinged together through the bending shaft. When the two groove sample clamps are in 180 degrees, samples are placed under the bending shaft in the groove sample clamps. As the two groove sample clamps are relatively closed, the samples are bent with the bending shaft as an axial center. The steel plate sample bending device utilizes the lever principle and a clamp structure, one person can conveniently conduct intergranular corrosion steel plate sample bend. Sample bending is standardized, the position is accurate, and the device is simple and cost of manufacture is low.
Description
Technical field
The utility model relates to a kind of steel plate sample bending apparatus.
Background technology
According to need of production, stainless steel, the stainless steel that particularly needs to weld often require to carry out the intercrystalline corrosion check.Sulfuric acid-copper sulphate corrosion test method is usually adopted in the intercrystalline corrosion check.By the GB regulation, the sample after " sulfuric acid-copper sulphate " solution boils is wanted to observe after the bending.The pressure head diameter has not only been stipulated in the sample bending, has stipulated at length that also crooked position, particularly weldment must carry out bending along melt run, and this has brought larger difficulty for bending work of sample.
Present domestic main employing vice bending method or a roller type bending apparatus method.Vice bending method equipment is simple, and is easy to operate, and its shortcoming is that the sample bending is lack of standardization, and the position is difficult to guarantee that particularly weldment is difficult to guarantee that elastic line on melt run, usually can cause invalidate the test because of the mistake of bending position.Propping up the roller type bending apparatus method is to adopt a roll-type support and the crooked pressure head of sample, utilizes common Material Testing Machine or large-scale compressor to carry out, although the method has overcome the shortcoming of vice bending method, equipment price is expensive, and operation convenience is poor.The Chinese patent of patent No. CN200820106041.9 " TG-FS-007 type stainless steel sample bender ", disclose and comprised support, hydraulic jack, Hydraulic Station, the fixing bending mechanism of pressure head, movable pressure head etc., having solved stainless steel intercrystalline corrosion samples does not have the problem of special-purpose bending equipment when physical property detects, but equipment price is expensive, it is large to take up room, inconvenient operation.
Summary of the invention
The purpose of this utility model is to overcome the prior art defective, and a kind of simple and practical steel plate sample bending apparatus is provided, and a people just can finish the bending work of sample by hand.
The technical solution of the utility model is achieved in that a kind of steel plate sample bending apparatus, it is, it by about two flute profile specimen holders form, it is hinged with it that bending axis passes the baffle plate of two flute profile specimen holder both sides, when two flute profile specimen holders are 180 °, sample places flute profile specimen holder bending axis below, and along with two flute profile specimen holders close up relatively, sample carries out bending take bending axis as the axle center.
Further, there is afterburning handle at two ends, two flute profile specimen holder left and right sides.
The utility model utilizes lever principle, adopts clamp type structure, can be easily to carry out by hand the intercrystalline corrosion steel plate sample by a people crooked, the crooked standard of sample not only, the position is accurate, and device is simple, cheap.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, the afterburning handle of 1-; The 2-sample; The 3-bending axis; 4-flute profile specimen holder; The 5-baffle plate.
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of steel plate sample bending apparatus, it by about two flute profile specimen holders 4 form, it is hinged with it that bending axis 3 passes the baffle plate 5 of two flute profile specimen holder 4 both sides, when two flute profile specimen holders 4 are 180 °, sample 2 places flute profile specimen holder 4 bending axis 3 belows, and along with two flute profile specimen holders 4 close up relatively, sample 2 carries out bending take bending axis 3 as the axle center.Two ends, two flute profile specimen holder 4 left and right sides are welded with afterburning handle 1.
In the practical operation, according to the size of sample 2, determine the width of flute profile specimen holder 4, the diameter of bending axis 3 and the height between bending axis 3 and flute profile specimen holder 4 bottoms, be advisable just sample being put into.The length of afterburning handle 1 should be long as far as possible under the prerequisite of handled easily, to save muscle power.Sample 2 is placed on the flute profile specimen holder 4, sample 2 positions to be bent place on the center line of bending axis 3, then with two afterburning handles 1 to closing up together, according to the requirement to sample 2 degree of crook, determine the degree that afterburning handle 1 closes up, to realize the bending of sample 2.
Claims (2)
1. steel plate sample bending apparatus, it is characterized in that: it by about two flute profile specimen holders form, it is hinged with it that bending axis passes the baffle plate of two flute profile specimen holder both sides, when two flute profile specimen holders are 180 °, sample places flute profile specimen holder bending axis below, along with two flute profile specimen holders close up relatively, sample carries out bending take bending axis as the axle center.
2. a kind of steel plate sample bending apparatus according to claim 1, it is characterized in that: there is afterburning handle at two ends, two flute profile specimen holder left and right sides.
