Whole riveted joint mould
The utility model belongs to the machine tool field, the integral body riveted joint mould in the production processes such as particularly a kind of diamond frame sawing bar.
In metal material is produced, ways of connecting mainly contains bolt connection, welding, bonding and riveted joint between the metal, during particularly the diamond frame sawing bar is produced, riveted joint is a wherein necessary procedure, at present its processing mode generally adopts riveting machine to pursue to rivet, but at many riveted joints of diamond frame sawing bar, causes working (machining) efficiency lower, processing cost is too high, and outward appearance is relatively poor.
Summary of the invention
The integral body riveted joint mould that the purpose of this utility model is to provide a kind of diamond frame sawing bar to improve the riveted joint working (machining) efficiency in process of production and improves the quality of products.
The purpose of this utility model is achieved in that a kind of whole riveted joint mould, comprise top mold frame 2 and following mould bases 3, last low punch 8,9 is connected up and down on the mould bases 2,3 by last bottom plate 6,7 respectively, last low punch 8,9 is fixed by last lower bolster 4,5 respectively, holding pad 10 is connected down on the mould bases 3, spring 11 is equipped with in the centre, and end plate 12,13 is sleeved on together by rivet 14 up and down, and rivet 14 is sleeved on the holding pad 10.
Whole riveted joint mould provided by the utility model owing to adopt whole riveted joint, is once riveted a plurality ofly, significantly enhances productivity, and has reduced working strength of workers; The control of employing mould helps controlling workpiece quality, has effectively reduced processing cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done a step explanation.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Find out by Fig. 1, top mold frame 2 of the present utility model and following mould bases 3 are separately fixed on the last lower table of punch press 1, punch press 1 is fixed on the ground, upper punch 8 and low punch 9 are connected up and down on the mould bases 2 and 3 by last bottom plate 6 and 7 respectively, last lower bolster 4 and 5 plays a supportive role to last low punch 8 and 9 respectively, holding pad 10 is connected down on the mould bases 3, spring 11 is equipped with in the centre, workpiece 15 is sleeved on by rivet 14 with end plate 12 and 13 up and down, rivet 14 is sleeved on the holding pad 10, forms an integral body riveted joint mould.
The course of work of the whole riveting die of the utility model is as follows:
At first start punch press 1 power supply, bottom plate 13 is placed on the holding pad 10, upper head plate 12 is sleeved on by rivet 14 with workpiece 15, after rivet 14 lower ends are sleeved on the bottom plate 13, open punch press 1 punching press switch, punch press 1 upper table, top mold frame 2, upper padding plate 4, upper mounted plate 6 and upper punch 8 will move downward together, when upper punch 8 touches rivet 14, holding pad 10 moves downward, low punch 9 is contacted with rivet 14, under about punch press 1 downward operational forces, rivet 14 deforms, and is filled in the counterbore on the bottom plate 14 punch press 1 upper table face backhaul then, drive top mold frame 2, upper padding plate 4, upper mounted plate 6 and upper punch 8 are finished the process of once riveting with backhaul together.
