Abstract
The utility model discloses a stainless steel intergranular corrosion sample bending device which aims at solving the problems that in terms of an existing sample bending device, a sample and a sample clamp are in sliding friction, so that labor is wasted and a bending shaft is prone to deformation. The stainless steel intergranular corrosion sample bending device is mainly composed of a left groove-shaped sample clamp and a right groove-shaped sample clamp. A bending shaft penetrates through baffles on the two sides of the two groove-shaped sample clamps and allows the groove-shaped sample clamps to be hinged together. The bottoms of the two groove-shaped sample clamps on the two sides of the bending shaft are respectively provided with two sleeve rollers laterally symmetric. The two ends of each sleeve roller penetrate through the baffles on the two sides of the groove-shaped sample clamps and can rotate. When an angle between the two groove-shaped sample clamps is 180 degrees, a sample is arranged between the bending shaft and the sleeve rollers and in the groove-shaped sample clamps, and along with the relative closing process of the two groove-shaped sample clamps, the sample is bent with the bending shaft serving as the axis. According to the stainless steel intergranular corrosion sample bending device, in the bending process, the sample and the sleeve rollers at the bottoms of the groove-shaped sample clamps are in rolling friction, friction force in the sample bending process can be reduced, labor is saved for operation, the bending shaft is not prone to damage, and the intergranular corrosion sample can be bent simply by a person.
Description
Technical field
The utility model relates to a kind of stainless steel intercrystalline corrosion samples bending apparatus.
Background technology
According to need of production, stainless steel, particularly need welding stainless steel often require to carry out intercrystalline corrosion inspection.Intercrystalline corrosion inspection usually adopts sulfuric acid-copper sulphate corrosion test method.By GB regulation, the sample after " sulfuric acid-copper sulphate " solution boils, to observe after bending.Sample bending has not only specified pressure head diameter, also specified in more detail bending position, particularly weldment must carry out bending along melt run, this has brought larger difficulty to bending work of sample.
Domestic main employing vice bending method or a roller type bending apparatus method at present.Vice bending method equipment is simple, easy to operate, and its shortcoming is that sample bending is lack of standardization, and position is difficult to ensure, particularly weldment is difficult to ensure that elastic line, in melt run, usually can cause invalidate the test because of the mistake of bending position.Propping up roller type bending apparatus method is to adopt a roll-type support and the bending 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, and equipment price costliness, operation convenience is poor.The patent No. is that the Chinese patent of CN201220566115.3 discloses a kind of steel plate sample bending apparatus, mainly by specimen holder, be used for afterburning handle and form, solved stainless steel intercrystalline corrosion samples does not have the problem of special bending equipment in the time that physical property detects.But this device is in use, between sample and specimen holder, be sliding friction, not only effort but also bending axis are easy to distortion, cause bending apparatus normally to use.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, and a kind of laborsaving durable stainless steel intercrystalline corrosion samples bending apparatus is provided.
The technical solution of the utility model is achieved in that a kind of stainless steel intercrystalline corrosion samples bending apparatus, mainly formed by two of left and right flute profile specimen holder, bending axis is hinged by it through the baffle plate of two flute profile specimen holder both sides, it is, on bending axis both sides, symmetrical cover roller is respectively equipped with in two flute profile specimen holder bottoms, cover roller two ends are through the baffle plate of flute profile specimen holder both sides can rotation, when two flute profile specimen holders are 180 °, sample is placed between flute profile specimen holder bending axis and cover roller, along with two flute profile specimen holders close up relatively, sample carries out bending taking bending axis as axle center,
Further, cover roller is respectively equipped with two two flute profile specimen holder bottoms.
Further, cover roller is made up of roll shaft and roller, and roll shaft fastens on the baffle plate of flute profile specimen holder both sides by nut lock, and roller is enclosed within the middle of roll shaft and can in flute profile specimen holder, freely rotates.
Further, respectively there is the long handle of adding at two ends, two flute profile specimen holder left and right.
When the utility model is bending, between sample and the cover roll roller of flute profile specimen holder bottom, be rolling friction, friction can reduce sample bending time, rapid operation and be not easy to damage bending axis, a people can carry out intercrystalline corrosion samples bending by hand, the not only bending specification of sample, position is accurate, and device is simple, cheap.

Detailed description of the invention
Be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in Fig. 2, a kind of stainless steel intercrystalline corrosion samples bending apparatus, mainly formed by two of left and right flute profile specimen holder 1, bending axis 2 is hinged by it through the baffle plate 3 of two flute profile specimen holder 1 both sides, in flute profile specimen holder 1 bottom, two, bending axis 2 both sides, two symmetrical cover rollers are respectively housed, cover roller is made up of roll shaft 5 and roller 6, roll shaft 5 fastens on the baffle plate 3 of flute profile specimen holder 1 both sides by nut lock, roller 6 is enclosed within the middle of roll shaft 5 and can in flute profile specimen holder 1, freely rotates, when two flute profile specimen holders 1 are 180 °, sample 4 is placed between flute profile specimen holder 1 bending axis 2 and the roller 6 of four cover rollers, along with two flute profile specimen holders 1 close up relatively, sample 4 carries out bending taking bending axis 2 as axle center, respectively there is the long handle of adding 7 at two flute profile specimen holder 1 two ends, left and right, are convenient to single labor-saving operation.
In practical operation, according to the size of sample 4, determine the width of flute profile specimen holder 1, the difference in height between the diameter of bending axis 2 and bending axis 2 and four cover rollers, just putting into sample 4 to be advisable.The length of handle 7 should be long as far as possible under the precursor of handled easily, to save people's muscle power.Sample 4 is placed between the roller 6 of bending axis 2 and four cover rollers, sample 4 position to be bent is placed on the center line of bending axis 2, then by two handles 7 to closing up together, to realize the bending of sample 4.According to the requirement to sample 4 degree of crook, determine the degree that handle 7 closes up.
When the utility model is bending, between sample 4 and the cover roll roller 6 of flute profile specimen holder 1 bottom, be rolling friction, friction can reduce sample 4 bending time, rapid operation and be not easy to damage bending axis 2, a people can carry out intercrystalline corrosion samples bending by hand, the not only bending specification of sample, position is accurate, and device is simple, cheap.
