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
The invention belongs to the hardware stamping mould applications, relate to hard alloy saw blade matrix Tooth punching mold.
Background technology
In the hard alloy saw blade matrix flute profile process of prior art, mainly contain processing modes such as punching press, laser cutting, line cutting.Because hard alloy saw blade tooth portion is less, adopt towards tooth processing, tooth portion shape can not be kept perfectly, and the limit phenomenon of seriously collapsing is arranged, and laser cutting and line cutting cost are higher.At present in hard alloy saw blade matrix production industry, the less demanding low washer of tooth portion mainly adopted towards tooth process; Medium-to-high grade, employing be laser cutting and line cutting processing, but working (machining) efficiency is low, cost is higher.
In the tooth process, all adopt monodentate to rush in row processing at existing hard alloy saw blade matrix.Because hard alloy saw blade matrix flute profile has a lot of wedge angles, flute profile is less simultaneously, in processing, can not solve the flute profile integrity issue at existing monodentate, tooth portion sharp corner very easily occur collapsing the limit, collapse phenomenons such as angle, matrix is very little at the later stage grinding allowance, and post-production can not be eliminated this defective, influences the weld strength of carbide alloy, in the tooth process, being prone to big or small tooth situation, can not satisfy the requirement of medium-to-high grade hard alloy saw blade simultaneously.
Summary of the invention
The technical problem to be solved in the present invention be eliminate saw bit matrix existing monodentate in the tooth process dash processing can not solve flute profile complete and occur tooth portion sharp corner collapse the limit, collapse problem such as angle, provide a kind of and can improve the hard alloy saw blade matrix Tooth punching mold that the flute profile crudy is good and working (machining) efficiency is high.
Purpose provided by the invention is achieved in that a kind of saw bit matrix Tooth punching mold, comprise top mold frame and following mould bases, die is fixed on down on the mould bases by die block, punch is fixed on the top mold frame by punch retainer, device for discharging is fixed on the punch retainer, punch and die are provided with slightly towards tooth and smart in tooth, slightly towards teeth size less than essence towards tooth.
Saw bit matrix Tooth punching mold provided by the invention, with the mould punch-die improvement, change bidentate into from existing monodentate, be in the operation front end tooth for slightly towards tooth, the latter be the essence towards tooth, dimensionally, slightly towards tooth be slightly less than the essence towards tooth.Adopt the bidentate mould to carry out towards tooth, be actually same tooth has been carried out slightly towards tooth and smart in the tooth two procedures, to slightly finish towards being punched on the same mould with essence, for the first time for slightly dashing, utilizing indexing means to select the flute profile after slightly dashing for the first time to be carried out essence behind the tooth calibration dashes, finish slightly dashing of another flute profile simultaneously, finish the tooth that dashes of whole flute profile and process.Guarantee the integrity degree of flute profile, solve the defective of present mould towards tooth processing.
Compared with prior art, the present invention has following advantage:
1. owing to adopt the bidentate stamping-out, improved the flute profile integrity degree of hard alloy saw blade matrix.
2. dash by essence, eliminate the limit phenomenon of collapsing of saw blade in the stamping-out process.
3. help improving the tooth calibration of carbide alloy.
4. improved the flute profile working (machining) efficiency of the medium-to-high grade lamellar body of carbide alloy.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is the plan structure schematic diagram of saw bit matrix of the present invention towards tooth processing.
Fig. 3 is that the present invention is slightly towards tooth and smart in the toothing schematic diagram.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of saw bit matrix Tooth punching mold, comprise top mold frame 7 and following mould bases 6, die 1 is fixed on down on the mould bases 6 by die block 3, punch 2 is fixed on the top mold frame 7 by punch retainer 4, device for discharging 5 is fixed on the punch retainer 4, and punch 2 and die 1 are provided with slightly towards tooth 11 and smart in tooth 12, slightly towards tooth 11 sizes less than essence towards tooth 12.
Engineering process of the present invention is as follows: at first saw bit matrix 9 is fixed on the indexing means 10, regulate the distance of saw bit matrix 9 and die 1, pneumatic punching machine 8 carries out towards tooth, after slightly having dashed towards tooth 11, by tooth calibration of indexing means rotation, slightly little than essence towards tooth 12 towards tooth 11, slightly forwarding to towards tooth 11 of subpunch smart carried out the fit essence on the tooth 12 and dashed like this, back and forth slightly dash towards essence, finishing the tooth that dashes of whole hard alloy saw blade processes, smart guaranteed the integrality of flute profile, eliminated the limit of collapsing that slightly dashes simultaneously, improved the tooth calibration of hard alloy saw blade matrix towards fit.
