Abstract
The invention discloses a machining method for a shaft sleeve. A stamping composite mold comprises a male mold body (1) and a female mold body (2) matched with the male mold body (1). A stamping hole through which the shaft sleeve (3) is stamped is formed in the female mold body (2), is in a step shape and comprises a first step (4) and a second step (5). The length of a puncher pin on the male mold body (1) is larger than the sum of the length of the first step (4) and the length of the second step (5). Corresponding through holes are formed in the male mold body (1) and the female mold body (2), a guide rod (6) is installed in the through holes, one end of the guide rod (6) is fixed to the female mold body (2), and the male mold body (1) performs vertical reciprocating movement along the guide rod (6). By means of the machining method for the shaft sleeve, due to the structure, production efficiency is greatly improved, and labor cost is saved; meanwhile, the stamped piece cannot generate many waste materials, raw materials are prevented from being wasted, and production cost is reduced.
Description
Technical field
The present invention relates to a kind of processing method of axle sleeve.
Background technology
Copper bush is the common part for back shaft on breaker, and the consumption on a breaker has 10 at least, and 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 on numerically controlled lathe boring, turning, bore hole, chamfering, whole process nearly 4 minutes, produces at most more than 100 axle sleeve every day.So not only length consuming time, increase the labour intensity of operating personnel, and output is very low, cannot meet actual user demand; Meanwhile, this kind of processing mode can produce a lot of copper junk, causes raw-material waste.
Summary of the invention
Technical problem to be solved by this invention is the processing method providing a kind of axle sleeve for problems of the prior art, its objective is while saving human and material resources, enhances productivity.
Technical scheme of the present invention is the die that this kind comprises punch for the mould processing axle sleeve and coordinate with it, described die is provided with the punching hole for going out 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, described punch and die are equipped with corresponding through hole, in through hole, guide post is installed, one end of guide post is fixed on die, and punch pumps along guide post;
The method utilizing above-mentioned punching-pressing composite mould to process axle sleeve comprises:
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, be applied to punch pressure, axle sleeve blank is suppressed into die by punch, then blanking, finally forms axle sleeve.
Described cutter sweep is knife edge die.
A processing method punch press with this kind of axle sleeve of said structure just can stamp out an axle sleeve in every 30 seconds, if this Design of Dies becomes the several axle sleeve of punching press one-shot forming, within one day, thousands of axle sleeves can be stamped out every day by calculation in 8 hours, compared to original every day more than 100, this technique substantially increases production efficiency, saves human cost, and stamping parts can not produce too many waste material simultaneously, avoid raw-material waste, reduce 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.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, and Fig. 2 is the structural representation of bottom bracket axle of the present invention.Combined from structure shown in Fig. 1-2, the die 2 that this kind comprises punch 1 for the punching-pressing composite mould processing axle sleeve and coordinate with it, described die 2 is provided with the punching hole for going out 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; Punch 1 and die 2 are equipped with corresponding through hole, are provided with guide post 6 in through hole, one end of guide post 6 is fixed on die 2, and punch 1 pumps along guide post 6.
The method utilizing above-mentioned punching-pressing composite mould to process axle sleeve comprises:
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, be applied to punch 1 pressure, axle sleeve blank is suppressed into die 2, then blanking by punch 1, final formation axle sleeve 3.
A processing method punch press with this kind of axle sleeve of said structure just can stamp out an axle sleeve in every 30 seconds, if this Design of Dies becomes the several axle sleeve of punching press one-shot forming, within one day, thousands of axle sleeves can be stamped out every day by calculation in 8 hours, compared to original every day more than 100, this technique substantially increases production efficiency, saves human cost, and stamping parts can not produce too many waste material simultaneously, avoid raw-material waste, reduce production cost.
The technical solution adopted in the present invention compared with prior art, has possessed property more economically, the feature of practicality, terseness, is worth industrially promotion and application.So the present invention has novelty, economy and practicality.
