Abstract
The utility model discloses a preparation facilities of power cable sheath dumbbell test piece, including dumbbell test block cutter, dumbbell test block cutter sets up the three edge of a knife at least side by side, and the three edge of a knife can the three dumbbell test block of a punching press with the sheet -punching machine cooperation. Dumbbell test block cutter bottom is that a steel sheet is as the sword base. Still include test block ejecting device, test block ejecting device includes the push -off pin base that test block push -off pin and this test block push -off pin were located perpendicularly, it has six test blocks to release the hole to open on the bottom steel sheet of dumbbell test block cutter, two holes on every edge of a knife, and the test block push -off pin one -to -one with test block ejecting device is put to test block release hole site. Cutter wherein, a plurality of dumbbell test pieces of can producing once improve work efficiency to the cutter quality is great, is favorable to the sheath that flattens, makes the specimen size accurate, and reduces the burr on test piece both sides, improves the satisfied rate of the dumbbell test piece of making. Wherein test block ejecting device makes things convenient for taking out of dumbbell test block.
Description
Technical field
The utility model relates to electric power dumbbell test specimen, specifically a kind of preparation facilities of power cable sheath dumbbell test specimen.
Background technology
In the detection of power cable, having a key name is the Interventions Requested of the aging forward and backward mechanical performance of sheath air-oven, mainly examines the performance of the resistance to natural aging of power cable restrictive coating. In the time that carrying out this test, laboratory first need to make dumbbell test specimen according to, standard, standard specifies that this test detects a cable sample and at least will make ten dumbbell test specimens, if and dumbbell test specimen in drawing process in gauge length fracture will be judged to invalid, and this is difficult to be avoided exactly, so at least should make in test 15 dumbbell test specimens. The making of dumbbell test specimen at present adopts single dumbbell cutting knife, can only make a test specimen at every turn, a sample of cable will be repeatedly die-cut at least ten five times, not only time-consuming, effort, and curling due to cable cover(ing) inertia, and the quality of dumbbell cutting knife is less, sheath can not be flattened, cause sample dimensions lack of standardization, thereby affect the accuracy of result of the test.
Summary of the invention
The purpose of this utility model is to provide a kind of preparation facilities of power cable sheath dumbbell test specimen, and easy to use, accuracy is high, and can effectively increase work efficiency.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, and a kind of preparation facilities of power cable sheath dumbbell test specimen, comprises dumbbell test piece cutting knife, described dumbbell test piece cutting knife is at least set up in parallel three edges of a knife, and three edges of a knife coordinate three dumbbell test pieces of a punching press of energy with sheet-punching machine. Also comprise test piece ejecting device, test piece ejecting device comprises the push-off pin pedestal that test piece push-off pin and this test piece push-off pin are vertically located, on the bottom steel plate of described dumbbell test piece cutting knife, have six test piece introduction holes, two holes of each edge of a knife, test piece introduction hole position is corresponding one by one with the test piece push-off pin of test piece ejecting device.
Described dumbbell test piece cutting knife bottom is that a block plate is as cutter pedestal.
Compared to prior art, the utlity model has following beneficial effect:
The utility model comprises a cutting knife, and multiple dumbbell test specimens of can producing once, increase work efficiency, and cutting knife quality are larger, are conducive to flatten sheath, make specimen size accurate, and reduce the burr on test specimen both sides, improves the satisfaction rate of manufacturing dumbbell test specimen. The utility model comprises a test piece ejecting device, facilitates the taking-up of dumbbell test piece.

Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
According to Fig. 1-4, a kind of preparation facilities of power cable sheath dumbbell test specimen, comprises dumbbell test piece cutting knife, and described dumbbell test piece cutting knife is at least set up in parallel 3, three edges of a knife of three cutter edges and coordinates three dumbbell test pieces of a punching press of energy with sheet-punching machine. Described dumbbell test piece cutting knife bottom is that a block plate 1 is as cutter pedestal. Also comprise test piece ejecting device, test piece ejecting device comprises the push-off pin pedestal that test piece push-off pin and this test piece push-off pin are vertically located, on the bottom steel plate of described dumbbell test piece cutting knife, have six test piece introduction holes 2, two holes of each edge of a knife, test piece introduction hole position is corresponding one by one with the test piece push-off pin 4 of test piece ejecting device.
This dumbbell test piece cutting knife adopts chromium steel material, and a dumbbell test piece cutting knife comprises three edges of a knife, and coordinating with sheet-punching machine can three dumbbell test piece of a punching press. Dumbbell test piece cutting knife bottom is a steel plate, and the contact that this is conducive to increase dumbbell cutting knife and cable cover(ing), makes cable cover(ing) smooth, the dumbbell specimen size specification cutting out.
The supporting test piece ejecting device of this dumbbell test piece cutting knife. After die-cut test piece, dumbbell test piece meeting is stuck in cutting knife, is difficult for taking out, if plucked out from cutting knife bottom by force, easily damages test piece. On the steel plate of the bottom of this cutting knife, have six circular holes, two, each edge of a knife, position is corresponding with the push-off pin of test piece ejecting device, after the die-cut end of test piece, ejecting device is inserted in the circular hole of cutting knife bottom, and test piece can be taken out, and can not damage test piece.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
