Abstract

The invention discloses a track link hot stamping cutting tool edge die which comprises an assembly die frame. The assembly die frame is provided with a rear blade, a hole surface blade, a front bladeand a rail surface blade which are connected in sequence. The rear blade, the hole surface blade, the front blade and the rail surface blade form a step-shaped arc tool edge in a surrounding mode. Ablade locking block is arranged on the outer side of the rear blade and the assembly die frame. The track link hot stamping cutting tool edge die is provided with the four blades, each blade can be repaired and replaced independently, all the cutting tool edges are straight-surface tool edges, no straight extension position exists, and the perpendicularity precision of the two side faces, the upper surface and the lower surface of a forge piece after cutting is high.

Description

technical field [0001] The invention belongs to the technical field of machine tool processing, and in particular relates to a thermal punching knife-edge mold for chain rail links. Background technique [0002] The hot-cut knife-edge mold device on the traditional press is an integral structure, as shown in the figure figure 1 and figure 2 Shown: the inner frame is used as a knife edge 13, the knife edge has a straight extension position 17 of 10mm, and the other is a slope 18 of 2-5 degrees. The two sides of the forging with this structure are not perpendicular to the upper and lower sides of the forging; the traditional incision cannot be damaged. Replacement requires slot milling, welding and reprocessing, which has a long maintenance period and high cost. And use the hot-cut knife-edge die set on a conventional press. Contents of the invention [0003] In view of this, the present invention provides a thermal punching knife-edge die for chain rail links to solve t...
