The sample mold is arranged on the base, and the spring rod sliding hole is formed in the base. The spring rod is installed inside the spring rod sliding hole, the side pressing mold is arranged on the spring rod in a sleeved mode, the male mold through hole is formed in the side pressing mold, the compression spring is arranged at the upper end of the side pressing mold and on the spring rod in a sleeved mode, the male mold fixing plate is connected with the upper end of the spring rod, the male mold is connected to the male mold fixing plate, the inverted-U-shaped upper mold base is connected to the upper end of the male mold fixing plate, and the hydraulic cylinder is connected to the inverted-U-shaped upper mold base. The male mold and the sample die are installed in a mode of sharing the same center line. According to the device, the process for preparing the sample of the forming limit curve (FLC) is simple, the process cycle of the sample is short, the size and shape accuracy of the sample is high, the flexibility is good, the structure is simple, operation is easy, and the labor intensity can be lowered.
Description
Technical field
The utility model relates to a kind of building mortion, specifically belongs to a kind of device of preparing tested steel plate forming limit curve sample.
Background technology
The shaping limit curve (FLC) of material is a core index of sheet metal formability, and its method of testing has concrete regulation in GB/T24171.2-2009 and ISO12004-2:2008.Along with the extensive use of finite element numerical simulation technology in stamping, also more and more many to the demand of sheet metal FLC, how the FLC of fast and flexible ground test material becomes very necessary.A preparation that important process is exactly sample in FLC test.At present, the preparation of sample adopts line cutting processing to form.Consider the needs of test, conventionally need the sample of 8 groups of different geometries, the sample of each geometry is 3, and the sample of line cutting processing has 24, and the processing of one group of sample needs work, and time of nearly one day just can complete.And exist in cutting on line process specimen surface is had to pollution, the detection of sample is had to certain influence.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of cycle of sample processing short, specimen size and form accuracy are high, simple in structure, easy to operate, can also adapt to the device of the preparation tested steel plate forming limit curve sample of sample process flexibility.
Realize the technical measures of above-mentioned purpose:
A kind of device of preparing tested steel plate forming limit curve sample, it is: its mainly by the sample mold arranging on base, base and spring lever sliding eye, be contained in the spring lever in spring lever sliding eye, punch through hole that the edge mould being set with on spring lever, edge mould are provided with, being sleeved on Compress Spring, the punch retainer being connected with spring lever upper end on spring lever, being connected in the punch on punch retainer, the hydraulic cylinder composition that is connected in the spill upper bolster of punch retainer upper end, connects on spill upper bolster in edge mould upper end; Punch and sample mold are concentricity, and line is installed.
It is characterized in that: the shape of cross section of punch bottom is circular arc.
It is characterized in that: two chutes are set centered by sample mold in base upper surface, in chute, are provided with mobile card article.
It is characterized in that: in spring lever lower end, sliding sleeve is housed.
Feature of the present utility model is: preparation FLC sample process is simple, and the sample process-cycle is short, and specimen size and form accuracy are high, flexibility good, and device structure is simple, easy to operate, can also reduce labor intensity.

The specific embodiment
Be described further below in conjunction with accompanying drawing:
A kind of device of preparing tested steel plate forming limit curve sample: processing sample mould 2 on the base 1 of processing, and centered by sample mold 2, at the symmetrical processed springs bar of base 1 sliding eye 3, spring lever 6 is contained in spring lever sliding eye 3, in the lower end of spring lever 6, sliding sleeve 13 is housed; Centered by sample mold 2, be processed with two chutes 11 in base 1 upper surface, moving blockage bar 12 is housed in chute 11; On the spring lever 6 of base 1 upper surface, fill edge mould 4, be processed with punch through hole 14 at the center of edge mould 4, on the spring lever 6 of edge mould 4 upper ends, be set with Compress Spring 7; The upper end of spring lever 6 adopts screw thread with punch retainer 8 or is connected by nut, to facilitate the replacing of punch 9, and adjusts the gap of different material when thick; Be bolted punch 9 in the center of punch retainer 8, the lower section of punch 9 is shaped as circular arc; Be connected by screw spill upper bolster 10 in punch retainer 8 upper ends, on spill upper bolster 10, be bolted hydraulic cylinder 5; Punch 9 is that concentricity line is installed with sample nib 2.
When use, first sample board is placed on base 1, the mobile card article 12 in mobile two draw-in grooves 11 positions; Primer fluid cylinder pressure 5; Under the thrust of hydraulic cylinder 5, spill upper bolster 10 and punch retainer 8 drive punch 9 to move downward, and spring lever 6 moves down thereupon in spring lever sliding eye 3; Thereby edge mould 4 contacts sample and make Compress Spring 7 pressurizeds on spring lever 6 compress sample, and punch 9 carries out stamping-out through punch through hole 14 to sample board, and symmetry repeats processing until complete the processing of sample.
This specific embodiment is for example best, not the restricted enforcement to technical solutions of the utility model.
