Embodiment Construction

[0016] like figure 1 , figure 2 and image 3 As shown, a saw blade matrix stamping die includes an upper mold frame 7 and a lower mold frame 6, the die 1 is fixed on the lower mold frame 6 through the die fixing plate 3, and the punch 2 is fixed on the lower mold frame 6 through the punch fixing plate 4. On the upper mold frame 7, the unloading device 5 is fixed on the punch fixed plate 4, the punch 2 and the die 1 are provided with rough punching teeth 11 and fine punching teeth 12, and the size of the rough punching teeth 11 is smaller than the fine punching teeth 12.

[0017] The engineering process of the present invention is as follows: first the saw blade base body 9 is fixed on the indexing device 10, the distance between the saw blade base body 9 and the die 1 is adjusted, the pneumatic punch press 8 punches the teeth, and after the rough punching teeth 11 are punched, pass The indexing device rotates a tooth index, and the rough punching tooth 11 is smaller than th...

Abstract

The invention discloses a tooth punching die for a saw blade substrate. The tooth punching die comprises an upper die carrier and a lower die carrier, wherein a female die is fixed on the lower die carrier through a female die fixing plate; a male die is fixed on the upper die carrier through a male die fixing plate; a discharging device is fixed on the male die fixing plate; the male die and the female die are provided with a rough punching tooth and a fine punching tooth; and the size of the rough punching tooth is smaller than that of the fine punching tooth. In the tooth punching die for the saw blade substrate, a single tooth of the conventional die is replaced by double teeth, a tooth at the front operation end is the rough punching tooth while a tooth at the back operation end is the fine punching tooth, and the size of the rough punching tooth is slightly smaller than that of the fine punching tooth. When a double-tooth die is used for tooth punching, rough tooth punching and fine tooth punching are actually performed on the same tooth on the same die and rough punching is performed firstly. After a tooth index is selected by an indexing device, fine punching is performed on one roughly-punched tooth type and rough punching is performed on the other tooth type at the same time, so that tooth punching processing of the entire tooth type is finished, the completeness of the tooth type is ensured and the defects of tooth punching processing of the conventional die are overcome.

Description

technical field [0001] The invention belongs to the field of metal stamping dies, and relates to a tooth punching die for a cemented carbide saw blade substrate. Background technique [0002] In the tooth profile processing of the cemented carbide saw blade substrate in the prior art, there are mainly processing methods such as stamping, laser cutting, and wire cutting. Due to the small tooth portion of the cemented carbide saw blade, the shape of the tooth portion cannot be kept intact by punching the teeth, and there is a serious collapse phenomenon, and the cost of laser cutting and wire cutting is relatively high. At present, in the production industry of cemented carbide saw blade substrates, low-grade chips with low requirements on the teeth are mainly processed by punching; medium and high-grade chips are processed by laser cutting and wire cutting, but the processing efficiency is low and the cost is high. [0003] In the tooth punching process of the existing cemen...
