Abstract
The utility model discloses a combined type pressure head for a bend test of materials, which comprises a base board, a support arranged on the base board through a bolt and a pressure head device fixedly arranged on a press machine. The pressure head device comprises a pressure head of a groove arranged along the radial direction and a pressure lever, the upper end of the pressure lever is fixedly connected with the press machine, and the lower end of the pressure lever is matched with the groove of the pressure head. The pressure lever and the pressure head are designed by adopting a detachable combined type, users can change the pressure head with different diameters according to different requirements in use, and the pressure lever can remain unchanged. The combined type pressure head not only saves cost, but also is fast and convenient in change, greatly improves test efficiency, is simple in structure and greatly strengthens practical applicability.
Description
Technical field
The utility model relates to a kind of material test machinery device, particularly a kind of pressure head that is used for the material bending process of the test.
Background technology
In the material tests field, according to the regulation of standard GB/T232-1999eqvISO7438:1985 metal material bend test method 5.1.3 clause: crooked pressure head diameter should be stipulated in products standards.Products standards all has clearly regulation to the crooked pressure head diameter of various sample thickness both at home and abroad, the corresponding a certain elbow diameter of promptly a certain thickness.The crooked pressure head of existing bend test device is structure as a whole, and diameter is single, only limits to a certain thickness sample and uses.For example, in the aluminium alloy extrusions field, existing domestic and international railcar body structure aluminium alloy extrusions products standards all adopts following regulation to the crooked pressure head diameter (2R) of different-thickness (e) sample: hollow profile: as e≤10mm, and 2R=8e; As e＞10mm, 2R=10e.Solid profile: as e≤5mm, 2R=6e; As 5＜e≤10mm, 2R=8e; As e＞10mm, 2R=10e.According to this products standards regulation, various sample thickness is selected differently curved pressure head diameter for use, sample thickness scope 1～25mm commonly used, pressure head bending diameter scope 8～250mm, the pressure head of 53 kinds of different-diameter specifications of actual needs.In the prior art, make the monoblock type pressure head of 53 kinds of different sizes, the very inconvenience of not only waste material, and replacing is wasted time and energy, and has a strong impact on test efficiency.
To above-mentioned deficiency, need work out a kind of economical with materials, change convenient and simple to operation and bending test pick-up unit efficiently.
The utility model content
In view of this, the purpose of the utility model provides a kind of bending test combined type pressure head of material, not only can practice thrift cost, and changes conveniently, and is simple to operation efficient, simple in structure, practical.
The purpose of the utility model realizes through following technical scheme: a kind of bending test combined type pressure head of material; Comprise base plate, be arranged on the bearing on the base plate and be fixedly installed on the indenter device on the pressing machine that said indenter device comprises the depression bar that pressure head is fixedly connected with pressing machine with the upper end, match with the groove of pressure head in the lower end that is disposed radially groove through bolt.
Further, said bearing is being arranged on along the mode that the base plate transverse horizontal moves on the base plate;
Further, said base plate is provided with scale;
Further, said pressure head is processed by aluminum alloy materials;
Further, said pressing machine is electronic type or hydraulic universal material testing machine.
The beneficial effect of the utility model: the bending test combined type pressure head of the material of the utility model; Compare with traditional integral type pressure head; Since depression bar and pressure head are adopted detachable combined type design, in use, can be according to different demands; Change the pressure head of different-diameter, and depression bar can remain unchanged.This device is not only practiced thrift cost, and changes quick and conveniently, has improved test efficiency greatly; Simple in structure, practicality strengthens greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode figure of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model; Fig. 2 is the user mode figure of the utility model.As shown in the figure: the bending test combined type pressure head of a kind of material of present embodiment; Comprise base plate 1, be arranged on the bearing 3 on the base plate and be fixedly installed on the indenter device on the pressing machine 7 that said indenter device comprises the depression bar 6 that the pressure head 5 that is disposed radially groove is fixedly connected with pressing machine with the upper end, match with the groove of pressure head 5 in the lower end through bolt 2.During use, as shown in Figure 2, test specimen 4 is lain in a horizontal plane on the bearing 3, pressure head 5 is placed on the test specimen 4; The groove of pressure head 5 is aimed at depression bar 6, and starting pressure machine 7, depression bar slowly descend and stretch into the groove of pressure head; Exert pressure downwards gradually, occur bending and deformation after making test specimen 4 stressed, accomplish test; As need make an experiment to the different-thickness test specimen, the pressure head of then changing different-diameter as required gets final product, and uses efficient and conveniently, has improved test efficiency greatly.
As the further improvement to the foregoing description, said bearing 3 is being arranged on the base plate along the mode that the base plate transverse horizontal moves.According to the test specimen demand of different-thickness, can adjust the position between two bearings 3 arbitrarily, satisfy the demand of different tests, universality is wide.
As the further improvement to the foregoing description, said base plate 1 is provided with scale.Can adjust the position of bearing accurately according to scale, adjustment is accurately quick, increases work efficiency.
As the further improvement to the foregoing description, said pressure head is processed by aluminum alloy materials.Adopt the aluminum alloy materials not only can weight reduction, handled easily, and also its rigidity also can satisfy the requirement of material bending tests such as aluminium alloy extrusions.
As the further improvement to the foregoing description, said pressing machine is electronic type or hydraulic universal material testing machine.Directly be fixedly connected through anchor clamps, need not the special special use equipment of exerting pressure, practice thrift cost, can promote the use of with electronic type or hydraulic universal material testing machine.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
