Abstract
The invention discloses a punching composite die for machining a shaft sleeve and a machining method of the punching composite die for machining the shaft sleeve. The punching composite die comprises a male die (1) and a female die (2) which is used in cooperation with the male die (1), wherein a punching hole used for punching the shaft sleeve (3) is formed in the female die (2), the punching hole is of a stair shape, and comprises a first step (4) and a second step (5), the length of a punch on the male die (1) is larger than the sum between the length of the first step (4) and the length of the second step (5), corresponding through holes are formed in the male die (1) and the female die (2) respectively, a guide rod (6) is installed in the through holes, one end of the guide rod (6) is fixed to the female die (2), and the male die (1) carries out vertical reciprocating motion along the guide rod (6). According to the structure of the punching composite die for machining the shaft sleeve and the machining method of the punching composite die for machining the shaft sleeve, production efficiency is greatly improved, the human cost is reduced, a large amount of waste cannot be produced by punching parts, waste of raw materials is avoided, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of for processing punching-pressing composite mould and the processing method thereof of axle sleeve.
Background technology
Copper bush be on breaker for the common part of back shaft, the consumption on a breaker has 10 at least, number is quite a lot of.Conventional processing technology is: first with sawing machine, copper rod is sawn into axle sleeve blank one by one, then boring on numerically controlled lathe, turning, bore hole, chamfering, whole process nearly 4 minutes, produces at most more than 100 axle sleeve every day.Length consuming time so not only, increase operating personnel's labour intensity, and output is very low, cannot meet actual user demand; Meanwhile, this kind of processing mode can produce a lot of copper junks, causes raw-material waste.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of for processing punching-pressing composite mould and the processing method thereof of axle sleeve for problems of the prior art, its objective is when saving human and material resources, enhances productivity.
Technical scheme of the present invention is that this kind comprises punch and the die coordinating with it for processing the punching-pressing composite mould of axle sleeve, described die is provided with for going out the punching hole of axle sleeve, and described punching hole is stairstepping, comprise first step and second step, the length of the drift on punch is greater than the length sum of first step and second step.
On described punch and die, be equipped with corresponding through hole, guide post is installed in through hole, one end of guide post is fixed on die, and punch pumps along guide post.
Utilize the method for above-mentioned punching-pressing composite mould processing axle sleeve to comprise:
1) first, with cutter sweep, copper rod is cut into the axle sleeve blank of several given sizes;
2) utilize punch press by after axle sleeve blank Automatic-heating, impose on punch pressure, punch suppresses axle sleeve blank into die, and then blanking, finally forms axle sleeve.
Described cutter sweep is knife edge die.
This kind with said structure just can stamp out an axle sleeve for every 30 seconds for processing punching-pressing composite mould and punch press of processing method thereof of axle sleeve, if this Design of Dies becomes the several axle sleeves of punching press one-shot forming, within one day, by 8 hours, calculate and can stamp out thousands of axle sleeves every day, than more than 100 of original every days, this technique has improved production efficiency greatly, saved human cost, stamping parts can not produce too many waste material simultaneously, avoid raw-material waste, reduced production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of bottom bracket axle of the present invention.
In Fig. 1-2,1: punch; 2: die; 3: axle sleeve; 4: first step; 5: second step.
The specific embodiment
Fig. 1 is structural representation of the present invention, the structural representation that Fig. 2 is bottom bracket axle of the present invention.From structure shown in Fig. 1-2 in conjunction with, this kind comprises punch 1 and the die 2 coordinating with it for processing the punching-pressing composite mould of axle sleeve, described die 2 is provided with for going out the punching hole of axle sleeve 3, and described punching hole is stairstepping, comprise first step 4 and second step 5, the length of the drift on punch 1 is greater than the length sum of first step 4 and second step 5.
On punch 1 and die 2, be equipped with corresponding through hole, guide post 6 is installed in through hole, one end of guide post 6 is fixed on die 2, and punch 1 pumps along guide post 6.
Utilize the method for above-mentioned punching-pressing composite mould processing axle sleeve to comprise:
1) first, with knife edge die, copper rod is cut into the axle sleeve blank of several given sizes;
2) utilize punch press by after axle sleeve blank Automatic-heating, impose on punch 1 pressure, punch 1 suppresses axle sleeve blank into die 2, and then blanking, finally forms axle sleeve 3.
This kind with said structure just can stamp out an axle sleeve for every 30 seconds for processing punching-pressing composite mould and punch press of processing method thereof of axle sleeve, if this Design of Dies becomes the several axle sleeves of punching press one-shot forming, within one day, by 8 hours, calculate and can stamp out thousands of axle sleeves every day, than more than 100 of original every days, this technique has improved production efficiency greatly, saved human cost, stamping parts can not produce too many waste material simultaneously, avoid raw-material waste, reduced production cost.
The technical solution adopted in the present invention compared with prior art, has possessed property more economically, and the feature of practicality, terseness, is worth in industrial promotion and application.So the present invention has novelty, economy and practicality.
