Cutting device for cutting tire component

Abstract

The invention discloses a cutting device for cutting a tire component. The cutting device structurally comprises a foot frame, a protection door, a physical embrittlement cutting device, a cutting boxbody, a control operation table, a maintenance door and a supporting bottom plate. The end, close to the physical embrittlement cutting device, of the foot frame is fixedly connected to the lower position of the front end face of the cutting box body in an electric welding mode, the protection door is mechanically connected with the middle position of the front end face of the cutting box body through a hinge, the physical embrittlement cutting device is arranged inside the cutting box body, and the end, close to the protection door, of the control operation table is fixedly connected to themiddle position of the right side of the front end face of the cutting box body in an electric welding mode. A cold air guide mechanism is used for controlling a cold air exhaust mechanism to exhaustcold air into the cutting box body, a hardening effect is produced to a tire, therefore, the toughness of the tire is reduced, stress to a cutter is reduced during cutting, therefore, cutter abrasionis reduced, and the service life of the cutter is prolonged.

Description

technical field [0001] The present invention relates to the field of tire cutting, in particular to a cutting device for cutting tire components. Background technique [0002] Cutting devices for cutting tire components are known to be of two types; cut-off cutters, or disc and rod cutters, cut-off cutters comprising upper and lower cutters, each with a straight cutting edge, the upper cutter along the A lower cutter moves vertically to form a cut in a tire component. Disc and stick cutters include a disc upper cutter and a bar lower cutter. The disc upper cutter travels in the longitudinal direction along the bar lower cutter while turning over Several turns are used to cut the tire part, the rod-shaped lower cutter has a larger cutting angle, the contact area between the upper cutter and the tire part is significantly smaller, and the increased cutting angle reduces the pressure required to cut the tire part Due to the great toughness of the tire in the prior art, the cut...

[0002] Cutting devices for cutting tire components are known in two types; part-off cutters or disc and rod cutters, part-off cutters comprising an upper knife and a lower knife, each having a straight cutting edge, the upper knife along the The lower cutter moves vertically to form a cut in the tire component. The disc and rod cutters include a disc-shaped upper cutter and a rod-shaped lower cutter. The disc-shaped upper cutter travels in the longitudinal direction along the rod-shaped lower cutter while turning Several turns to cut the tire part, the rod-shaped lower knife has a larger cutting angle, the contact area between the upper knife and the tire part is significantly smaller, and the increased cutting angle reduces the pressure required for cutting the tire part In the prior art, due to the great toughness of the tire, the cutter is subjected to excessive stress during cutting, which easily increases the wear of the cutter and even breaks the cutter
