Abstract

The utility model relates to a multifunctional sheet bending test support used for a material tension and bending tester, which mainly solves the technical problem of requirement of changing a support in 180-degree bending during an existing bending testing. The technical scheme of the sheet bending test combined support includes that a V-shaped upper mold is fixed onto an upper mold connecting unit, a connecting threaded opening is arranged in the middle of the upper mold connecting unit, a V-shaped notch of a V-shaped lower mold of a T shape matches with the V-shaped upper mold, the vertical end of the V-shaped lower mold is inserted into a chute of a bottom mold, a return spring connects one transverse end of the V-shaped lower mold with the bottom mold, a pressing bending space is formed between another transverse end of the V-shaped lower mold and the bottom mold, and a bottom mold positioning hole is arranged on the lower surface of the bottom mold. The sheet bending test combined support replaces a traditional supporting roller type bending device and a pressing device on the material tension and bending tester, requires no repeated change, realizes bending positioning, fixed angle bending and rapid pressing by the support, achieves the purposes of convenience, high efficiency and accurate angular bending, and is particularly suitable for 180-degree bending testing of sheets.

Description

Thin plate bending test combinations bearing

Technical field: the utility model relates to a kind of multi-functional sheet bending test bearing that is used on the material extending Apparatus for Bending at low-temp.On the material extending Apparatus for Bending at low-temp, use this device to replace traditional roll-type bending apparatus and pressuring flat device, need not to change repeatedly, on same device, realize bending position location, fixed angle bending, flatten fast, reach purpose convenient, efficient, accurate angular bend, be particularly suitable for 180 ° of folding tests of thin plate.

Background technology: the material width of regulation bending test is less than 50mm in the GB//T232-1999 metal material bend test method, and a lot of product needed are simulated the crooked operating mode when using, need do width greater than the 50mm bending test, particularly some customer requirements is done the bending test of 300～400mm width.Bend test device on the material extending Apparatus for Bending at low-temp generally is fit to the sample of width less than 100mm, and needs two cover bend test devices when 180 ° of bendings, is bent to certain angle respectively earlier, changes another set of mould again and flattens sample, tests loaded down with trivial details.

The relevant bend test device patent situation of retrieval, the CN94227143.2 Bending support has been introduced a kind of turnover plate type bend test device that shows angle of bend, it also is a kind of turnover plate type bend test device that the convertible clod wash of CN02270163.X attaches, and above-mentioned turnover plate type bend test device still will increase pressuring flat device when 180 ° of bending tests.

The utility model content: the purpose of this utility model provides an a kind of traditional roll-type bending and thin plate bending test bearing that flattens of replacing, and mainly solves the technical matters that need change bearing when having 180 ° of bendings of bending test now.Need not to change repeatedly during 180 ° of bendings of the utility model, on same device, realize bending position location, fixed angle bending, pressing, reach convenient, efficient, accurate crooked purpose, be particularly suitable for 180 ° of folding tests of thin plate.

The technical solution of the utility model is: a kind of thin plate bending test combinations bearing; the V-type patrix is fixed on the patrix linkage unit; patrix linkage unit middle part has the connection screw socket; the V-type notch of the V-type counterdie of T type and V-type patrix coupling; the V-type counterdie perpendicular end insert the bed die chute; the horizontal end and the bed die of V-type counterdie are connected with back-moving spring, form between horizontal end of another of V-type counterdie and the bed die and flatten the curved space, and the bed die lower surface is provided with the bed die pilot hole.

Both sides at bed die are provided with handle; The upper surface of V-type counterdie is carved with long apart from location indentation and short distance location indentation, and the realization bending position is accurately located.

The invention has the beneficial effects as follows: at the deficiency of existing test unit, design a kind of combination bend test device that is used on the material stretch test machine, the present invention has the accurate angular bend of V-type, 180 ° of bendings, realize accurately multiple function such as location of bending position, is particularly suitable for width and carries out 180 ° of bendings greater than the thin plate of 100mm.

Description of drawings:

Figure 1 shows that the utility model structural front view

Fig. 2 is the right view of Fig. 1.

Among Fig. 1: 1-connects screw socket, 2-patrix linkage unit, 3-V type patrix, 4-V type counterdie, 5-thin plate sample, 6-bed die, 7-handle, 8-bed die pilot hole, 9-back-moving spring, 10-is long locatees indentation apart from location indentation, 11-short distance.

Embodiment:, further specify the utility model below in conjunction with example and accompanying drawing 1,2:

A kind of thin plate bending test combinations bearing, V-type patrix 3 is fixed on the patrix linkage unit 2, patrix linkage unit 2 middle parts have and connect screw socket 1, the V-type notch of the V-type counterdie 4 of T type and V-type patrix 3 couplings, the upper surface of V-type counterdie 4 is carved with long apart from location indentation 10 and short distance location indentation 11, and the realization bending position is accurately located.V-type counterdie 4 perpendicular end insert bed die 6 chutes, the horizontal end and the bed die of V-type counterdie 4 are connected with back-moving spring 9, form between horizontal end of another of V-type counterdie 4 and the bed die and flatten the curved space, be provided with handle 7 in the both sides of bed die, the bed die lower surface is provided with bed die pilot hole 8.

The utility model is connected patrix linkage unit 2 by connecting screw socket 1 with the universal testing machine crossbeam, bed die 6 is by bed die pilot hole 8 and universal testing machine table positions, handle 7 is used for mobile bed die 6, and V-type counterdie 4 relies on back-moving spring 9 and chute to realize easy on and off, accurately move with bed die 6.

Thin plate sample 5 is at first placed V-type counterdie 4 upper surfaces, locate indentation 11 pair thin plate sample location by long apart from location indentation 10 or short distance according to requirement of experiment, rise after the universal testing machine workbench loads, V-type patrix 3, patrix linkage unit 2 keep static with the universal testing machine crossbeam, the stressed groove angle that is bent to V-type counterdie 4 of thin plate sample, universal testing machine worktable return, back-moving spring 9 makes V-type counterdie 4 returns, the thin plate sample 5 of bending is placed between V-type counterdie 4 and the bed die 6, repeat to load flattening sample again, realize 180 ° of bendings.
