Abstract
The invention discloses a die for cutting off pin bolts. The die comprises an upper die and a lower die, the upper die is installed on an upper die fixing plate, a backing plate is arranged on the upper die fixing plate, and a die shank is installed on the backing plate through a die shank fixing plate; the lower die is located under one side of the cutting-off face of the upper die, two or more grooves used for storing pin bolts are formed in the lower die, the lower die is fixed on a lower die fixing plate, the lower die fixing plate is installed on a lower die plate, and a locating plate used for locating the pin bolts is arranged at the side, where the lower die fixing plate is located, of the lower die plate. By means of the die, the problems that existing hardware cutting is low in efficiency and low in machining precision can be solved.
Description
Technical field
The present invention relates to Machining Technology field, especially a kind of mould for cutting off the handwares such as pin.
Background technology
At present, the general enterprise all of cutting of the handwares such as pin all adopts abrasive wheel cutting machine cutting, the otch of cutting is irregular, because the benchmark of processing does not ensure, the length of every section is also uneven, and the precision of cutting is lower, and cuts piece by piece one by one, working (machining) efficiency is also very low, and labour intensity is also very large; In addition, can produce a large amount of dust, fly upward in workshop during cutting, environmental pollution is very large, has a strong impact on the healthy of operating personnel.
Summary of the invention
Problem to be solved by this invention is to provide a kind of pin and cuts off mould, low to solve existing handware cutting efficiency, the problem that machining accuracy is low.
In order to solve the problem, technical scheme of the present invention is: this pin cuts off mould and includes upper die and lower die, and described patrix is arranged on upper mould fixed plate, and described upper mould fixed plate is provided with backing plate, and described backing plate is provided with die shank by die shank fixed head; Described counterdie is positioned at a side-lower of described patrix section, described counterdie is provided with at least two for placing the groove of pin, described counterdie is fixed on counterdie fixed head, described counterdie fixed head is arranged on lower bolster, and described lower bolster is provided with the location-plate for shop bolt in the side of described counterdie fixed head.
In technique scheme, more specifically scheme can be: described upper mould fixed plate is connected with described backing plate by least four soket head cap screws, and described counterdie fixed head is connected with described lower bolster by least four soket head cap screws; Described lower bolster is provided with immediately below described patrix the technique through hole for blanking.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This pin cuts off mould and adopts the cutting realizing the handwares such as pin of mould, and cut off the handwares such as pin with patrix counterdie, the otch of cutting is smooth, shearing length always, the pin uniform length of processing; Location-plate ensure that cut-out benchmark, ensure that the precision of cut-out; Counterdie is provided with at least two for placing the groove of pin, and can cut off at least two pieces pin, working (machining) efficiency is greatly improved simultaneously.This pin is used to cut off mould, both pollution-free, machining accuracy and working (machining) efficiency can be improved again.

Fig. 2 is the A-A place sectional view of Fig. 1;
Fig. 3 is the B-B place sectional view of Fig. 1;
Fig. 4 is the C direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This pin as shown in Figures 1 to 4 cuts off mould, and it includes patrix 5 and counterdie 9, and pin cuts off the cutting realizing handware that mould adopts mould, handware is cut off with patrix 5 counterdie 9, cutting otch smooth, shearing length always, the handware uniform length of processing.Patrix 5 is arranged on upper mould fixed plate 4, and upper mould fixed plate 4 is provided with backing plate 3, and upper mould fixed plate 4 is connected with backing plate 3 by four soket head cap screws 6, and backing plate 3 is provided with die shank 2 by die shank fixed head 1.Counterdie 9 is positioned at a side-lower of patrix 5 section, and counterdie 9 is provided with three for placing the groove 10 of pin, and can cut off at least two pieces pin, working (machining) efficiency is greatly improved simultaneously.Counterdie 9 is fixed on counterdie fixed head 11, and counterdie fixed head 11 is arranged on lower bolster 7, and counterdie fixed head 11 is connected with lower bolster 7 by four soket head cap screws 6.Lower bolster 7 is provided with the location-plate 8 for shop bolt in the side of counterdie fixed head 11; Location-plate 8 ensure that cut-out benchmark, ensure that the precision of cut-out.Lower bolster 7 is provided with immediately below patrix 5 the technique through hole 12 for blanking, the clout of cut-out can fall from the technique through hole 12 for blanking.
