Description
Technical Field
The utility model relates to a motorcycle engine part technical field specifically is a crank base forming die for motorcycle.
Background
The crank is a main accessory for transmitting torque in the engine of the motorcycle, and the frequency of application in the engine is high. The existing crank is usually cast and integrally formed by steel, the flatness of the die cannot be guaranteed by the existing crank base forming die, the machining precision of the crank is affected, errors can occur when the crank is installed, the crank is scratched easily in the demoulding process, the quality of the crank is affected, and the working efficiency is reduced.
Based on this, the utility model designs a crank base forming die for motorcycle to solve above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a crank base forming die for motorcycle to the machining precision who proposes among the solution above-mentioned background art is low, the articulate problem of drawing of patterns fish tail.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a crank base forming die for motorcycle, includes forming die, forming die includes stock guide, upper die and bed die. The middle of the upper portion of the upper die is provided with a discharging hole, the material guide plate is located on the upper side of the upper die, the lower die is installed on the base, a crank die is arranged inside the lower die, and the upper die is installed below the stamping platform.
Preferably, a circle with the height of 20mm and the width of 10mm is arranged above the lower die.
Preferably, the crank die inside the lower die is of a detachable design.
Preferably, the material of the forming die is HIO type alloy hot-work steel.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, convenient to use can effectively protect the mould the life, and the easier drawing of patterns has improved work efficiency.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a top view of the lower mold of the present invention;
fig. 3 is a schematic view of the upper mold of the present invention.
In the drawings, the components represented by the respective reference numerals are listed below:
in the figure: 1. forming a mold; 2. a material guide plate; 3. an upper die; 4. a lower die; 5. a discharging port; 6. A base; 7. a crank die; 8. and (4) stamping the platform.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a crank base forming die for motorcycle, includes forming die 1, forming die 1 includes stock guide 2, mould 3 and bed die 4. The middle of the upper portion of the upper die 3 is provided with a discharging hole 5, the guide plate 2 is located on the upper side of the upper die 3, the lower die 4 is installed on the base 6, a crank die 7 is arranged inside the lower die 4, and the upper die 3 is installed below the stamping platform 8.
Wherein, the lower mould top is 20mm high, and the wide circle that is 10mm can with the better airtight space that forms of last mould, helps the mould drawing of patterns.
The crank die inside the lower die is detachably designed and can be replaced by dies of other models, so that the production cost is saved.
The forming die is made of HIO type alloy hot-working steel, and is good in heat resistance and low in surface grain size.
One specific application of this embodiment is: the lower die is arranged in the crank die, the lower die and the base are fixedly arranged, material leakage caused in the pressing process is avoided, the material is placed in a middle discharging hole of the upper die through the material guide plate, and the upper die is pressed by the pressure platform to enable the upper die and the lower die to be quickly closed and sewn.
In the description of the present invention, the terms "in", "up", "down", and the like indicate orientations or state relationships based on the orientations or state relationships shown in the drawings, and are only for convenience of description and simplified description, but do not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "fixed" are to be understood in a broad sense, and for example, may be fixedly mounted, detachably mounted, or integrally mounted; the installation can be direct or indirect through an intermediate medium. To those of ordinary skill in the art, the specific meaning of the above terms in the present invention is understood according to the specific situation.
The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention.
