Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying examples.

Referring to fig. 1 and 2, a rubber mat cutter for flanges comprises:

the device is characterized in that a positioning cone 1 is arranged at the bottom of a cuboid support 8, and the positioning cone and the cuboid support are connected through threads. The center of the bracket 8 is provided with a rectangular through hole, and the long strip-shaped arm 4 passes through the through hole and can slide back and forth in the through hole. Two cutters 6 and a hole cutter 72 are hung on the long arm 4, and the lengths of the cutters 6 and the hole cutter 72 are the same. The sliding and rolling components 2 are symmetrically arranged on two sides of the bracket 8, and the two sliding and rolling components 2 are arranged to be vertical to the long arm 4. Including sleeve 22 in the smooth subassembly 2 that rolls, there is ball spring 24 in the sleeve 22, ball spring 24 connects the upside inner wall at sleeve 22, and ball spring 24's below is connected with square dog 23, and a recess has been seted up to the lower surface of dog 23, and ball 21 is spherical and through the laminating of magnetic force in the recess. A circular hole is formed below the sleeve 22, the diameter of the circular hole is smaller than that of the ball 21, and a part of the ball 21 is exposed out of the sleeve 22.

A rectangular guide groove 42 is formed in the long arm 4, and the cutter 6 passes through the guide groove 42 and is mounted on the long arm 4. The top of the cutting knife 6 is a cutting knife hanging head 63, and the diameter of the cutting knife hanging head 63 is larger than that of the guide groove 42 and is positioned above the guide groove 42. The middle part of the cutting knife 6 is provided with a cutting knife fastener 62, the cutting knife fastener 62 is positioned below the guide groove 42 and can move up and down along the cutting knife 6 through threads, and the cutting knife fastener 62 can move down until being detached. The bottom of the cutter 6 is provided with a cutter head 61, and the edge of the cutter head 61 is perpendicular to the long arm 4. A hole cutting knob 73 is arranged above the hole cutting device 7, the hole cutting device 7 penetrates through the guide groove 42 and is hung on the long arm 4 through the hole cutting knob 73, the position of the hole cutting device 7 is between the two cutters 6, and a circular hole cutting knife 71 is arranged below the hole cutting device 7 in a threaded mode. There is fastening knob 3 in the top central authorities of support 8, and knob screw thread 31 has been seted up to the outer wall in fastening knob 3 central authorities, and fastening knob 3 passes through knob screw thread 31 to be installed in support 8, and knob cushion 32 is installed to the bottom of fastening knob 3, and knob cushion 32 can realize the contact with long arm 4. The upper surface of the long arm 4 is engraved with scale marks 41, and the scale marks 41 are opened along the direction of the guide groove 42 and have the same length as the guide groove 42.

The working principle of the embodiment is as follows: during cutting operation, the two cutters 6 can be adjusted to the required radius, then rotate around the positioning cone 1, cut simultaneously, and once shaping, respectively cut out the internal diameter and the external diameter of the ring-shaped rubber mat. And after the cutting is finished, the hole cutting device 7 is adjusted to the required radius position according to the position of the flange bolt, and bolt through holes are cut in sequence. The working efficiency is greatly improved. The two sliding and rolling assemblies 2 and the cutter 6 form a triangle, so that the whole device becomes stable, and the falling accident can not happen during the cutting operation. Since the whole device is in circular motion during cutting, the use of the spherical balls 21 facilitates the rotation of the device.
