Description

Be used for reinforcing bar tensile test with pressing from both sides face structure

Technical Field

The utility model belongs to the technical field of the tensile test technique and specifically relates to a be used for reinforcing bar tensile test with pressing from both sides face structure is related to.

Background

With the continuous development of detection technology, the requirements of the material detection field are higher and higher, various types of detection items are more and more, and metal materials generally relate to the fields of stretching, compression, hardness, impact and the like. Wherein the tensile test comprises high-temperature tensile, room-temperature tensile, low-temperature tensile and other directions. Different experimental projects contain different equipment, different connection type and different clamp faces, and the clamp face of different grade type is often unable general because the difference of sample size, and tensile test is destructive test generally moreover, in different experimental projects, can waste a large amount of clamp faces, and this has not only caused a large amount of materials extravagant, has also improved spare parts and has occupied the stock, has reduced the availability factor of material and equipment for actual manufacturing cost increases. Meanwhile, the clamping surface of the testing machine is frequently replaced according to different sizes of the samples, and the testing time is wasted.

Clamping the sample through a clamping surface structure in the process of the steel bar tensile test; the existing clamping surface structure is only provided with one vertical groove, and when the notch of the vertical groove is seriously abraded, the vertical groove needs to be replaced in time, the replacement is frequent, the cost is high, and the test time is wasted; and the clamping size range is small, and the universality is poor.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims to solve the technical problem that a be used for reinforcing bar tensile test to use presss from both sides a structure is provided, and its notch can the use conversion, avoids often changing a structure, practices thrift the cost.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

this be used for reinforcing bar tensile test with pressing from both sides a structure, include pressing from both sides a structure body and establish the recess that is used for the centre gripping reinforcing bar on pressing from both sides a structure body, be equipped with on pressing from both sides a structure body and be used for the fixed orifices of installation, the recess that presss from both sides a structure body is a set of criss-cross centre gripping recess, the centre gripping recess is V type recess.

Further, the group of crossed clamping grooves are crossed V-shaped grooves.

The group of crossed clamping grooves is three crossed V-shaped grooves or a crossed V-shaped groove shaped like a Chinese character 'mi'.

One side surface of the clamping surface structure body is an installation surface, and the other side surface of the clamping surface structure body is a clamping surface; the clamping face structure body is of an integral structure, and the clamping groove is formed in the clamping face.

The depth of the V-shaped grooves crossed on the clamping surface structure body is different.

The number of the fixing holes is four, and the fixing holes are formed between the adjacent clamping grooves.

Compared with the prior art, the utility model, have following advantage:

the clamping face structure for the steel bar tensile test is reasonable in design, and the crossed V-shaped notch is designed on the clamping face, so that when one notch is seriously abraded, the other notch can be replaced for use, the clamping face structure is prevented from being frequently replaced, and the cost is saved; the diameter range that V type notch clamp face can satisfy the centre gripping reinforcing bar is 5 ~ 40mm, has increased the centre gripping scope of reinforcing bar sample.

Drawings

The contents of the description and the references in the drawings are briefly described as follows:

fig. 1 is a schematic view of a clamping surface structure of the present invention.

Fig. 2 is a schematic view of the structure of the clamping surface of the present invention.

1. the clamping face structure comprises a clamping face structure body, 2 fixing holes, 3 first clamping grooves and 4 second clamping grooves.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the clamping surface structure for the steel bar tensile test comprises a clamping surface structure body 1 and a groove which is arranged on the clamping surface structure body and used for clamping a steel bar, wherein a fixing hole 2 used for mounting and fixing is arranged on the clamping surface structure body, the groove of the clamping surface structure body is a group of crossed clamping grooves, and the clamping grooves are V-shaped grooves.

Through design a alternately V type notch on pressing from both sides the face, realized when notch wearing and tearing are serious, can change another notch and use, avoid often changing and press from both sides a structure, practice thrift the cost.

The depths of the crossed V-shaped grooves on the clamping surface structure body are different; the diameter range that V type notch clamp face can satisfy the centre gripping reinforcing bar is 5 ~ 40mm, has increased the centre gripping scope of reinforcing bar sample.

Or the split type clamping face structure body is a split type structure, the split type clamping face structure body is arranged on a bottom plate, half of notches are formed in the split type structure, adjacent split type structures are in butt joint to form V-shaped grooves, the split type structures are fixed on the bottom plate through independent fasteners, and can be detached and replaced according to the abrasion condition, so that follow-up trimming is facilitated, and the cost is reduced.

The group of crossed clamping grooves are crossed V-shaped grooves or the group of crossed clamping grooves are three crossed V-shaped grooves or crossed V-shaped grooves shaped like a Chinese character 'mi'.
