Abstract
The utility model is a kind of charger ensureing uniform load on stand under load width, comprises pressure head body and loads pressure head.Described pressure head body is cylindrical shape, is fine thread structure, is connected with testing machine in pressure head bodies top; Pressure head body center section is designed to circular two I-shaped structures, and the middle thin-walled of I-shaped structure has very important significance to obtaining test figure accurately.And pressure head body and the separately design of loading pressure head, namely pressure head body bottom portion is concave structure, and the convenient convex structure with loading pressure head coordinates, and both pass through screw fastening.During thermal treatment, pressure head body and loading pressure head separately carry out, and can ensure the pliability of pressure head body, loading pressure head can be made again to have higher hardness and wearing quality, and after loading pressure head wearing and tearing, be convenient for changing new loading pressure head, need not again process pressure head body part, greatly save experimentation cost.
Description
Technical field
The utility model relates to a kind of charger that can ensure uniform load on stand under load width.
Background technology
Charger described in the utility model is mainly used in thin plate bending torture test, wherein loading pressure head is vital part when testing, existing loading pressure head directly adopts bloom, and loading pressure head and pressure head body are made of one structure, namely pressure head body connects the middle interconnecting piece loading pressure head and testing machine and divides, and it is flexible poor that this bloom pressure head directly loads thin plate, easily causes unbalance loading, make the stand under load fracture of thin plate local, test figure deviation is larger.Moreover traditional indenter body and the structure loading pressure head one are made troubles to thermal treatment, because pressure head body requires certain flexibility, and load pressure head and require certain hardness and wearing quality.
For the problems referred to above, pressure head body center section is designed to circular two I-shaped structures by the utility model, is thin wall profile in the middle of I-shaped structure; And by pressure head body and the separately design of loading pressure head, both are coordinated by concaveconvex structure, so both can easily ensure the toughness of pressure head body and load the hardness of pressure head during thermal treatment, again can when carrying out repeated bend test, change the loading pressure head of wearing and tearing at any time, and need not again processing experiment machine connect pressure head body part, therefore greatly can saving experimentation cost, having very important significance to obtaining test figure accurately.
Utility model content
The purpose of this utility model is: provide a kind of charger that can ensure uniform load on stand under load width, comprises and loads pressure head and pressure head body.Object is by pressure head body and loads pressure head separately design, loading pressure head top is bulge-structure, pressure head body center section is designed to circular two I-shaped structure and bottom is recessed structure, both are connected by concaveconvex structure, and separately thermal treatment, can pressure head body toughness and load the hardness of pressure head, can not repeat under the prerequisite of processing pressure head body again, realize quick-replaceable wearing and tearing being loaded to pressure head, save experimentation cost.
The technical solution of the utility model is: a kind of charger that can ensure uniform load on stand under load width, comprises pressure head body, loads pressure head, connects socket head cap screw.By pressure head body and the separately design of loading pressure head, separate thermal treatment by performance requirement.Pressure head body is cylindrical shape, and top is that fine thread is connected with testing machine, and pressure head body center section is two I-shaped structures, and the centre of I-shaped structure is thin-wall construction; Pressure head body bottom portion concave structure has the through hole wearing screw, and the top loading pressure head is convex structure, has internal thread above.During installation, pressure head body bottom portion concave structure is coordinated with the top convex structure of pressure head, with hexagon socket head cap screw, both is fixed.During pressure head wearing and tearing, only need directly socket head cap screw to be pulled down, the pressure head that quick-replaceable is new.
The charger that can ensure uniform load on stand under load width that the utility model proposes, can not need, under the prerequisite repeating to process pressure head body, to realize the quick-replaceable of wearing and tearing pressure head.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in four accompanying drawings, 1-pressure head body, 2-loads pressure head, 3-socket head cap screw, 4-connecting thread, 5-body recess, 6-through hole, 7-pressure head protuberance, 8-threaded hole, 9-thin plate.
Accompanying drawing 1 is overall wiring layout, and wherein pressure head body 1 is connected with loading pressure head 2 by socket head cap screw 3.Accompanying drawing 2 is schematic diagram of pressure head body 1, and pressure head body 1 is connected with testing machine by fine thread 4, is penetrated by socket head cap screw 3 by the through hole 6 on body recess 5.Accompanying drawing 3 is the schematic diagram loading pressure head 2, loads pressure head 2 and is coordinated with body recess 5 by pressure head protuberance 7, guarantee load center line centering, loads on pressure head protuberance 7 and has threaded hole 8, come with pressure head body 1 fastening.Accompanying drawing 4 is applied on thin plate 9 by the assembly of accompanying drawing 1.
The utility model can ensure the charger of uniform load on stand under load width, before the test, first intact loading pressure head 2 is fixed on pressure head body 1, then the fine thread 4 on pressure head body 1 is connected and fixed with the internal thread of testing machine, pressure head 2 directly contacts with test thin plate 9, and pulsed load is applied on thin plate 9 by pressure head body 1 and pressure head 2.
Above-described embodiment only for technical conceive of the present utility model and feature are described, its object is to allow person skilled in the art can understand the utility model and content and implement according to this, practical range of the present utility model can not be limited with this.If do not depart from spirit and scope of the present utility model, the utility model is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in claim of the present utility model.
Claims (1)
1. one kind can ensure the charger of uniform load on stand under load width, this device is by loading pressure head and pressure head body forms, it is characterized in that loading pressure head separates with pressure head body to design, loading pressure head top is bulge-structure, for circular and be processed as two I-shaped structure and bottom is recessed structure in the middle part of pressure head body, both are connected by concaveconvex structure.
