Abstract
The utility model relates to moulds, in particular to a large-size gear mould. The large-size gear mould comprises a left mould and a right mould which can be mutually combined, a left mould cavity and a right mould cavity are respectively formed in the left mould and the right mould, the left mould cavity and the right mould cavity are respectively formed by grooves matched with a gear body and a gear, and when the left mould and the right mould are combined, the left mould cavity and the right mould cavity form a sealed cavity matched with the entire gear in a surrounding mode. The large-size gear mould enables heated blank to be formed in a punching mode through the left mould and the right mould, the blank produces lamination which is not on the working panel of the gear in the process of punch forming, the working effect of the gear is not affected, a large-size gear is directly formed in a welding mode without polish machining, machining efficiency is improved, and labor power and time are greatly saved.
Description
Technical field
The utility model relates to mould, relates in particular to a kind of mould for the large scale gear moulding.
Background technology
Along with China greatly develops basis instrument construction, the construction machinery industry of China has also obtained development at full speed, need to use large-sized gear in a lot of engineering machinery, usually adopt man-hour first the moulding of gear sectional stamping large scale gear is added, various piece is being welded into gear wheel.Existing to the moulding of gear sectional stamping normally first with blank heating, again by upper die and lower die with the blank punch forming that heats, but blank can produce lamination in upper and lower die stamping forming process, lamination can be on the working face of gear, affect the working effect of gear, thereby the gear after upper and lower die stamping moulding also needs further polishing processing just can make finished product, required complex process, manpower and time that working (machining) efficiency is low, waste is a large amount of.
The utility model content
In order to address the above problem, the utility model provides a kind of large scale gear mould, it is characterized in that: comprise can be mutually involutory left mould and right mould, be formed with respectively left die cavity and left die cavity on described left mould and the right mould, described left die cavity and right die cavity form by having with the suitable groove of gear body and the gear teeth respectively, when left mould and right mould are involutory, left die cavity and right die cavity surround one with the suitable annular seal space of whole gear.
Further, described left mould and/or have and have demoulding hole on the right mould.
The utlity model has following beneficial effect:
The large scale gear mould that the utility model provides, by left mould and right mould with the blank punch forming that heats, blank produces lamination not on the working face of gear in the punch forming process, can not affect the working effect of gear, need not processing through polishing, can directly be welded into large-sized gear, improve working (machining) efficiency, greatly saved manpower and time.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the left mould schematic diagram of the present embodiment large scale gear mould.
Fig. 2 is the right mould schematic diagram of the present embodiment large scale gear mould.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, shown in Figure 2, a kind of large scale gear mould, comprise can be mutually involutory left mould 1 and right mould 2, be formed with respectively left die cavity and left die cavity on left mould 1 and the right mould 2, left die cavity forms by having with suitable gear body recess 11 and the gear teeth groove 12 of gear, right die cavity forms by having with suitable gear body recess 21 and the gear teeth groove 22 of gear, when left mould 1 is involutory with right mould 2, left die cavity and right die cavity surround one with the suitable annular seal space of whole gear.Have demoulding hole 23 on the right mould 2.
The above, it only is the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
1. large scale gear mould, it is characterized in that: comprise can be mutually involutory left mould and right mould, be formed with respectively left die cavity and left die cavity on described left mould and the right mould, described left die cavity and right die cavity form by having with the suitable groove of gear body and the gear teeth respectively, when left mould and right mould are involutory left die cavity and right die cavity surround one with the suitable annular seal space of whole gear.
2. large scale gear mould according to claim 1 is characterized in that: described left mould and/or have and have demoulding hole on the right mould.
