Abstract

The utility model provides a mold for forging an aluminium alloy motorcycle wheel hub, which is easy to produce and has high product percent of pass and high strength. The mold comprises an upper mold and a lower mold, wherein the periphery of the upper mold is matched and provided with an upper mold sleeve through a step; the periphery of the lower mold is matched and provided with a lower mold sleeve through a step; the inner side of the lower mold sleeve is movably sheathed with a lower mold adaptor which is combined by segments, and the bottom of the lower mold adaptor is supported against the top of the lower mold; and the bottom of the lower mold is also provided with a lifting mechanism. The mold has simple structure and can forge products conforming to design requirements by using a forging method for one time, thereby greatly shortening the processing time causing low waste of raw materials and improving the product percent of pass. The product has high mechanical strength and high impact resistance, and the molecular structures of product raw materials are uniform and compact. Because solid aluminium alloy is used for forging the motorcycle wheel hub, the process of remelting aluminium alloy is omitted, no environmental pollution can be caused, and the planned objectives for energy saving and emission reduction of the country is met.

Description

A kind of mould of reflectal hub of motorcycle
Technical field
The utility model belongs to motorcycle and manufactures the field, specially refers to a kind of mould of reflectal hub of motorcycle.
Background technology
The Al-alloy motorcycle wheel hub has characteristics attractive in appearance, lightweight, therefore is loved by the people.In the market Al-alloy motorcycle wheel hub is normally poured into a mould and is formed, there is the shortcoming that amount of machining is big in the production process, wastage of material is big, a process of fusing is again arranged during the cast aluminum alloy, easy contaminated environment, and because the characteristics of casting technique, the qualification rate of product is low, and the mechanical strength of product is low, and anti-collision performance is poor.Therefore, it is imperative to seek a kind of production technology of new Al-alloy motorcycle wheel hub.
Adopt Forging Technology to produce the Al-alloy motorcycle wheel hub, can utilize metal forming machinery that aluminum alloy blank is exerted pressure, make it produce plastic deformation, can eliminate defectives such as cast condition that aluminum alloy blank produces is loose in smelting process, optimize heterogeneous microstructure, owing to preserved complete metal streamline, the mechanical performance of forging generally is better than the foundry goods of same material simultaneously.But the periphery of hub of motorcycle generally all has the cambered surface of an indent, and traditional forging mold is very inconvenient when the discharging and the demoulding, and production efficiency is lower, therefore is difficult to utilize Forging Technology to produce the Al-alloy motorcycle wheel hub.
The utility model content
The purpose of this utility model is the mould that proposes a kind of convenient for production, product percent of pass is high, intensity is high reflectal hub of motorcycle.
The mould of reflectal hub of motorcycle of the present utility model comprises upper die and lower die, and key is that the periphery of described patrix is equipped with Upper Die-sleeve by the step cooperation; The periphery of described counterdie is equipped with lower die-sleeve by the step cooperation, and the inboard movable sleeve of described lower die-sleeve is connected to the counterdie ring set, and described counterdie ring set is that segmentation combines, and its base abuts is at the top of counterdie, and the bottom of described counterdie also is provided with material jacking mechanism.
Upper Die-sleeve is the patrix center fixedly, is convenient to discharging; Lower die-sleeve not only is used for fixing counterdie and counterdie core, plays the role of positioning, and also helps the top that reduces the die joint overlap and forging when and hits power; The most important thing is: the counterdie ring set is fixing counterdie core not only; bear the outward expansion force that produces when the counterdie core overwhelms power; also because the counterdie ring set is that segmentation combines; and with the lower die-sleeve pivot bush unit; in the demoulding, can at first utilize material jacking mechanism that counterdie ring set and counterdie core integral body are deviate from lower die-sleeve earlier; and then the counterdie ring set taken apart, core is separated with the counterdie ring set, stripping operation is convenient.
For reducing the die joint overlap; above-mentioned mould is when moulding is closed, and the outer wall of patrix lip stretches into 6~8 millimeters of the inwalls of counterdie ring set lip, can block overlap automatically after forging; therefore need not artificial excision overlap behind forging process, improved production efficiency and product quality.
The top of described counterdie ring set is higher than the top of lower die-sleeve, helps the demoulding.
The arranged outside of described Upper Die-sleeve has step, to be used to lift Upper Die-sleeve and patrix, easy-unloading.
The inboard of described counterdie ring set is an arc convex, fits with the shape face of wheel hub.
The mould structure of reflectal hub of motorcycle of the present utility model is simple, can significantly shorten process time by the disposable product that adheres to specification that forges of method that forges, and wastage of material is few, the product percent of pass height, and process time is short.The product mechanical strength height of being produced, anti-collision performance is strong, and the products material molecular structure is evenly tight.Owing to be to forge processing with solid-state aluminium alloy, there is not the fusion process again of aluminium alloy, so can not produce environmental pollution, solved cast aluminum alloy environmental pollution problems, met the planned target of national energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the structural representation of the mould of reflectal hub of motorcycle of the present utility model.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, the mould of the reflectal hub of motorcycle of present embodiment comprises patrix 1 and counterdie 2, and key is that the periphery of described patrix 1 is equipped with Upper Die-sleeve 3 by step 11 cooperations; The periphery of described counterdie 2 is equipped with lower die-sleeve 4 by step 21 cooperations; the inboard movable sleeve of described lower die-sleeve 4 is connected to counterdie ring set 5; described counterdie ring set 5 is for segmentation combines, and its base abuts is at the top of counterdie 2, and the bottom of described counterdie 2 also is provided with material jacking mechanism 6.
For reducing the die joint overlap; above-mentioned mould is when moulding is closed, and the outer wall of patrix 1 lip stretches into 6~8 millimeters of the inwalls of counterdie ring set 5 lips, can block overlap automatically after forging; therefore need not artificial excision overlap behind forging process, improved production efficiency and product quality.
The top of described counterdie ring set 5 is higher than the top of lower die-sleeve 4, helps the demoulding.
The arranged outside of described Upper Die-sleeve 3 has step 31, easy-unloading.
The inboard of described counterdie ring set 5 is an arc convex, fits with the shape face of wheel hub.
When forging, Upper Die-sleeve 3 is used for fixing patrix 1, and lower die-sleeve 4 and counterdie ring set 5 play the role of positioning in conjunction with fixedly counterdie 2 and counterdie core 7, and power is hit on the top that also helps when reducing die joint overlap and forging; The most important thing is: counterdie ring set 5 is fixing counterdie core 7 not only; bear the outward expansion force that produces when counterdie core 7 overwhelms power; also because counterdie ring set 5 combines for segmentation; and with lower die-sleeve 4 pivot bush units; in the demoulding, can at first utilize material jacking mechanism 6 that counterdie ring set 5 and counterdie core 7 integral body are deviate from lower die-sleeve 4 earlier; and then counterdie ring set 5 taken apart, core 7 is separated with counterdie ring set 5, stripping operation is convenient.
