Description
Technical field
The present invention relates to the field of measuring technique of leather shrinking temperature parameter, particularly a kind of device for preparing leather sample with diplopore.
Background technology
Shrinkage temperature is the major parameter of sign leather thermal stability, detects the shrinkage temperature of leather quickly and accurately, in time instructing production technology and providing related data and support to have great significance for specialty research.
At present at home and abroad; No matter be the most original pointer leather shrinkage temperature tester or improve after semi-automatic or self-action leather shrinkage temperature tester; Produce and the fixing means of leather sample all are essentially identical, promptly manual sample preparation, and crocodile clip is fixed.Detailed process is: the standard cutter through Pneumatic pressure formula leather ST is equipped with is produced the length 50mm of national standard QB/T2713-2005 requirement and the leather sample of width 3mm; And then be fixed in through crocodile clip and heat measurement on the testing jig.It is bulky that yet this method for making sample not only exists ST; Unhandy problem; And the noise of the compressor that is equipped with of pneumatic type ST more polluted the quiet working environment in laboratory, also has more serious problem to be owing to be fixed in through crocodile clip and heat measuring mode on the testing jig and give artificial the making a big impact of measurement result.Utilize crocodile clip fixedly leather sample to the influence of measurement result mainly from two aspects: but one be since leather sample belong to stressed after the flexible material of deformation, so residing tightness difference problem when causing leather sample fixedly owing to operator's reasons such as personal habits; Second is the slippage problem of leather sample during measuring that the difference of the elastic force of crocodile clip own and the passivation that causes pressing from both sides mouthful along with the prolongation of service time and elastic force reduce to cause.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art; The object of the present invention is to provide a kind of device for preparing leather sample with diplopore; Can conveniently produce the leather sample that two ends have diplopore, thereby hang fixed pattern to the mode of fixing leather sample by the clipping diplopore that is improved to, with effective solution fixedly in the leather sample operating process human factor to the adverse effect of measurement result; Improve measuring accuracy, have simple in structure, in light weight, convenience operation.
To achieve these goals, the technical scheme of the present invention's employing is: a kind of device for preparing leather sample with diplopore includes support 8; Support 8 bottoms are provided with hydraulic press 9, and the pressure output end of hydraulic press 9 is provided with backing plate 10, and backing plate 10 two ends are provided with spring 11; The other end of spring 11 is connected with location-plate 12, and last location-plate 12 bottoms are provided with tool matrix 1, and it is rectangular groove 2 for circular, middle part that the bottom of tool matrix 1 is provided with two ends; The oral area of groove 2 is a dumbbell shape cutting knife 6; Two ends are provided with and cut hole cutter 3 in the groove 2, cut hole cutter 3 and are the cylinder type hollow cutter, and the root of cutting hole cutter 3 is provided with jackscrew 7; Jackscrew 7 is a cylinder type hollow, cuts at two and is provided with appearance hole 5, top between the hole cutter 3.
Described hole cutter 3 diameters of cutting are 2.6mm.
Describedly cut length that hole cutter 3 stretches out groove 2 through jackscrew 7 precessions or screw out and regulate, in case since its when in use more easy abrasion causes the hole not cut through, guarantee that through precession jackscrew 7 it stretches out degree, thereby make normal use.
The present invention produces cutter through special design owing to what adopt; Promptly be provided with the anxious hole of cylindrical cutter at the two ends of tool matrix; Can guarantee that the cutting knife once-forming produces the leather sample with diplopore; The circular leather that cuts away can be through cutting the hole cutter cylindrical cavity and the cylindrical cavity of jackscrew discharge, improved the efficient and the quality of sampling, have simple in structure, in light weight, convenience operation.
