Description

Pneumatic stamping sampling machine

Technical field

The utility model relates to a kind of coiled material detection experiment utility appliance, particularly a kind of Pneumatic stamping sampling machine.

Background technology

In coiled material detection experiment, as waterproof roll, be made up of pitch, rubber or other organic synthesis materials, there is good water proofing property and higher pliability; For another example leather coiled material, then have higher pliability.The test samples cutting out multiple same shape, same size is in advance needed when carrying out Performance Detection and testing experiment to coiled material.Due to coiled material, as waterproof roll, leather coiled material have higher pliability, require that evenly applying larger cutting force just can cut out sample on the one hand; Require on the other hand to cut while tested coiled material cutting part pressing, multiple test samples that could cut out by examination criteria requirement meet the requirements in shape, size.

Prior art 1 is hand power screw sheet-punching machine conventional at present, adopt manual rotation shaking tray, impel be installed on screw tip pressure head cut the sample cutter detected coiled material be opposite to downwards on work top cut out detection experiment need sample, be installed in cutting process and screw tip pressure head cuts sample cutter periphery discontinuity, away from screw tip pressure head to cut the cutting force that the sample cutter edge of a knife obtains less, cause the sample that cuts out and examination criteria to require that error is larger.

Prior art 2 is Chinese patent CN201420783993.X, which provide a kind of waterproof roll hydraulic pressure sampling machine, " there is bracing frame, base, top board, lower platen and cutter head; lower platen is positioned over above base; cutter head is fixed on top board; it is characterized in that; bracing frame internal upper part is provided with hydraulic cylinder; hydraulic cylinder push rod contacts with bracing frame top, it is fixed head in the middle part of bracing frame, have connecting link and connecting shaft between hydraulic cylinder base plate and top board, the two, through fixed head, the connecting link between hydraulic cylinder base plate and fixed head overlaps and has spring; Described hydraulic cylinder has pressure release gauge tap and crank insert port, and described top board has magnet." " in use, first on top board, place cutter head, utilize the suction of magnet to fix, then below cutter head, coiled material to be sampled is placed, afterwards, close the pressure release gauge tap of hydraulic cylinder, crank is put into crank insert port, shake crank makes hydraulic cylinder push rod rise, and then top board is slowly declined together with cutter head, cutting coiled material, after having cut, open the pressure release gauge tap of hydraulic cylinder, top board returns to original position under the action of the spring.”

, in use jointly there is following defect and deficiency in waterproof roll hydraulic pressure sampling machine disclosed in the hand power screw sheet-punching machine of prior art 1 and prior art 2:

1, testing efficiency is not high, and operator's labour intensity is large.Because prior art 1 " adopts manual rotation shaking tray, impel the cutter head be installed on the screw tip pressure head detected coiled material be opposite on work top to cut out the sample of detection experiment needs downwards."; Prior art 2 is " crank being put into crank insert port; shake crank makes hydraulic cylinder push rod rise; and then top board is slowly declined together with cutter head; cut coiled material ", thus all need to consume one's strength, if the operator that arm strength is less, when running into the larger tested coiled material of the high and thick degree of pliability, then be difficult to realize manually cutting out sample, even if cut successfully, also time and effort consuming, inefficiency, error are larger.

2, be difficult to cut out multiple test samples that error is very little in shape, size, thus affect the accuracy of detection experiment result.Just owing to being utilize to cut out sample manually, in addition fail to push down in advance in cutting process and there is flexible coiled material be cut position and fixed, for the coiled material that pliability, thickness are different, or thickness, the pliability difference of same coiled material owing to certainly existing, the sample error in shape, size cut out will be caused comparatively large, thus affect the accuracy of detection experiment result.
