Embodiment Construction

[0013] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0014] Such as figure 1 The shown hot forging die for a cutting piece includes a forging die 1, a hot forging capacity core 2, an oil passage 3 and an oil groove 4. The forging die 1 is provided with a hot forging capacity core 2 matching the rotor punching piece, and the forging Die 1 is provided with a number of horizontal oil passages and longitudinal oil passages, and several horizontal oil passages and longitudinal oil passages are intertwined and connected to form oil passage 3. Annular oil groove 4 is arranged on forging die 1, and oil groove 4 is arranged around hot forging capacity core 2 and It communicates with the oil channel 3 , a pl...

Abstract

The invention discloses a hot forging die for a cutting sheet. The hot forging die comprises a forging die, a hot forging containing cavity, an oil passage and an oil groove, the forging die is provided with the hot forging containing cavity matched with a rotor punching piece, a plurality of transverse oil passages and longitudinal oil passages are formed in the forging die, the plurality of transverse oil passages and longitudinal oil passages are connected in a staggered way to form the oil passage, the annular oil groove is arranged in the forging die, the oil groove is arranged around thehot forging containing core and communicated with the oil passages, a plurality of oil groove branches are arranged between the oil groove and the hot forging containing core, and a plurality of cooling holes are formed in the forging die. The hot forging die has the advantages that the structure is simple, through the mutual cooperation of the oil passage and the oil groove, the lubricating oilto pass through and flow in the hot forging containing cavity, the degree of hot wear and crack damage of the forging die is reduced, the lubrication and cooling effects are obvious, the service lifeof the mold is effectively prolonged, the product precision is ensured, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of cutting blade dies, in particular to a cutting blade hot forging die. Background technique [0002] With the increasing number of machinery industries, more mechanical products need to be processed. Usually, the first step in the processing of each product needs to be cut and shaped. At present, cutting pieces are processed by hot forging dies, and the stability of hot forging dies directly affects the quality stability of cutting pieces. The structure of the hot forging die in the prior art is relatively simple, and fatigue crack damage and thermal wear are the two main reasons for the failure of the hot forging die. , the industrialization cost is high. [0003] Therefore, in order to solve the above-mentioned existing problems, the present invention provides a new technical solution. Contents of the invention [0004] The object of the present invention is to provide a cutting piece hot forging di...
