Abstract
The utility model relates to a roll forging shaping mould belonging to the class of long shafts. An upper mould is fixed on the upper main shaft of a roll forging machine, and a lower mould is fixed on the lower main shaft of the roll forging machine. Grooves which are formed by the upper mould and the lower mould respectively form a circular shape, an elliptical shape with a variable cross section, a circular shape with a variable cross section and an elliptical shape with a variable cross section. The grooves with the situations can be assembled on a set of mould. The utility model improves the production quality and the production efficiency, improves the labor environment and reduces the production cost.
Description
The utility model belongs to the rollforming mould of major axis type objects, relates generally to the prong shaping dies of one steel fork.
Steel fork is the widely used hand tools of department such as railway, mine, farm, at present, manufacturer adopts pneumatic hammer to forge the mode of production of prong both at home and abroad, it is low that this mode of production that freely forges exists production efficiency, heat often, labour intensity is big, work under bad environment, product quality can not guarantee, defective such as finished product is low.
The purpose of this utility model is to provide a kind of roll forging mould of steel fork prong shaping, can improve productivity effect, reduces labour intensity, improves the quality of products.
The utility model adopts the upper die and lower die of band groove, and the shape that its upper and lower mould groove is formed is respectively circular, variable cross-section ellipse, the circular and variable cross-section ellipse of variable cross-section.
The groove combination of four kinds of situations is on a mold, and its patrix is installed on the forging roll on the main shaft, and counterdie is fixed on the forging roll lower main axis.
The utility model compared with prior art has:
1, production efficiency height.Owing to use mould, adopted the prong roll-forging process, improve more than 3 times than open die forging production technology.Surfacing, smooth, even thickness has improved the utilization rate of material, has reduced cost.
3, improved work situation.Free process of tin noise is big, and the labour intensity height adopts the roller process of tin, has reduced noise, has reduced labor strength.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 circular patrix, the oval patrix of 2 variable cross-sections, the circular patrix of 3 variable cross-sections, the oval patrix of 4 variable cross-sections, 5 circular counterdies, the oval counterdie of 6 variable cross-sections, the circular counterdie of 7 variable cross-sections, the oval counterdie in 8 these cross sections, 9 basic modes, 10 basic modes.
The oval patrix 2 of circular patrix 1, variable cross-section, the circular patrix 3 of variable cross-section and the circular patrix 4 of variable cross-section are fixed on the basic mode 10, then basic mode 10 are installed on the forging roll on the main shaft.Circular counterdie 5, the oval counterdie 6 of variable cross-section, circular counterdie 7 of variable cross-section and the oval counterdie 8 of variable cross-section are fixed on the basic mode 9, then basic mode 9 are installed on the forging roll lower main axis.Earlier base-material is entered circular trough during use, and then roll-in 2～4 times repeatedly in the oval and variable cross-section circular trough, put into the type groove of oval patrix 7 of variable cross-section and counterdie 3 compositions at last at variable cross-section.
Claims (2)
1, steel fork shaping dies comprises the upper die and lower die of being with groove, it is characterized in that the formed shape of upper and lower mould groove is respectively that circle, variable cross-section are oval, the circular and variable cross-section ellipse of variable cross-section.
2, steel fork shaping dies according to claim 1 is characterized in that being combined in the groove of several situations on the mold.
