Detailed Description

The present invention will be further explained by describing preferred embodiments of the present invention in detail with reference to the accompanying drawings.

First, a foam punching tool according to an embodiment of the present invention will be described with reference to fig. 1 to 4, which is used for punching a circular hole in foam, and the application scenarios thereof are wide.

As shown in FIGS. 1 to 2, the foam punching tool of the embodiment of the utility model comprises a circular knife, a steel sheet 2 and a connecting module.

Specifically, as shown in fig. 1-2, in this embodiment, the circular knife comprises cutter body 11 and blade 12, blade 12 sets up the bottom at cutter body 11, design through the circular knife can be to the foamed plastic cutting circular port, provide convenience for the cutting of foamed plastic circular port, and can be according to the corresponding cutting depth who adjusts the circular knife of the degree of depth of foamed circular port cutting, steel sheet 2 sets up the top at cutter body 11, steel sheet 2 plays supplementary effect, it is simpler to realize the rotation cutting operation of circular knife, and adopt the form of steel sheet 2 also more save space, reduce the cost, connecting module links to each other with cutter body 11 and steel sheet 2, be used for connecting cutter body 11 and steel sheet 2, realize the dismantlement installation of circular knife and steel sheet 2, thereby can adapt to the circular knife of different diameters as required.

Further, as shown in fig. 1, in this embodiment, the connection module includes: a plurality of to spacing gap 31, a plurality of to spacing gap 31 symmetry setting in the bottom of steel sheet 2, adjacent spacing gap 31 parallel arrangement, steel sheet 2 through one of them pair of spacing gap 31 and cutter body 11 joint, can realize the circular sword of different diameters and the cooperation joint of one of them pair of spacing gap 31 in steel sheet 2 bottom through a plurality of to spacing gap 31, realize cutting the circular port of different diameters.

Further, as shown in fig. 1, in the present embodiment, the distance between any pair of limiting slits 31 may be, but is not limited to, 16mm, 20mm, 25mm, 30mm, 32mm, 35mm, and circular knives with different diameters may be adapted by the difference of the distances.

Further, as shown in fig. 2 and 4, in the present embodiment, the cutter body 11 is shaped as a hollow cylinder, which is convenient for matching with the steel sheet 2 and ensuring the regularity of the cut round hole.

Further, as shown in fig. 2, in the present embodiment, an axial center line of the cutter body 11 coincides with a vertical center line of the bottom surface of the steel sheet 2, so that the steel sheet 2 is located at a center position of the cutter body 11, the steel sheet 2 is convenient to rotate to drive the cutter body 11 to rotate, and the occurrence of rotation deviation is prevented.

Further, as shown in fig. 1, in this embodiment, the foam piercing tool according to an embodiment of the present invention further includes: a pair of arc arch 4, a pair of arc arch 4 symmetry set up in the both sides of steel sheet 2, and a pair of arc arch 4 can play the effect of handle, makes things convenient for rotatory steel sheet 2, also plays the function of preventing the hand protector, prevents that operating personnel from because the 2 water caltrops of steel sheet are too sharp, easy fish tail.

When the circular cutting tool is used, firstly, the cutting position of the foam plastic is marked, the steel sheet 2 is held by a hand, the blade 12 on the circular knife is pressed on the foam plastic to be cut, and the tool is rotated while the blade is pressed, so that a required circular hole can be cut.

The foam punching tool according to the embodiment of the utility model is described above with reference to fig. 1-4, so that the problem that the operation of cutting a circular hole in foam is inconvenient because no tool for cutting a circular hole in foam is available at present is solved, and the device has the advantages of simplicity, durability, low manufacturing cost and the like.

It should be noted that, in the present specification, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
