Technical field

The utility model relates to a kind of mould, relates in particular to a kind of spheroid and rolls mould.

Background technology

At present, make sphere part in the industry, owing to receive the restriction of many-sided factor, the molding mode that generally adopts adopts spheroidal graphite cast-iron for casting, material, according to the different size requirement, makes corresponding mould, and monoblock cast forms.Yet, the foundry goods that this kind processing mode is produced, its production cost is high, and unit price is more expensive than general steel plate, and it is in order to guarantee to cast the yield rate of sphere part, and the spheroid wall of design is thicker, and processing capacity is big, and it is many to expend machining period, and production efficiency is low.For head it off, part producer adopts four-roll plate bending machine to make sphere part, yet it is the problem that perplexs for a long time that its spheroid rolls mould always.

The utility model content

The purpose of the utility model is to provide a kind of spheroid to roll mould to the problems referred to above, and low to solve original spheroid processing mode stock utilization, production cost is high, and labour intensity is big, the problem that production efficiency is low.

The purpose of the utility model is to realize through following technical scheme:

A kind of spheroid rolls mould, comprises upper die and lower die, and said upper die and lower die integral body is cylindric; Said patrix is made up of upper die base and patrix briquetting, the dismountable top roll that is installed on four-roll plate bending machine of said upper die base, and be in transmission connection with top roll; Said patrix briquetting is the projection with radian, and it circumferentially is arranged at the upper die base outer surface, and said counterdie is made up of lower die base and counterdie groove; Said lower die base is dismountable to be installed on the lower roll of four-roll plate bending machine; And be in transmission connection with lower roll, the arc groove of said counterdie groove for being complementary with the patrix briquetting, and it circumferentially is arranged at the lower die base outer surface.

Further, said upper die base and lower die base constitute by symmetrically arranged left pedestal and right pedestal.

Further, be provided with screwed hole on the patrix briquetting that the left pedestal of said upper die base and right pedestal outer surface circumferentially are provided with, and upper die base be fixed in top roll through bolt.

Further, be provided with screwed hole on the counterdie groove that the left pedestal of said lower die base and right pedestal outer surface circumferentially are provided with, and lower die base be fixed in lower roll through bolt.

Preferably, said upper die base is in transmission connection through key and top roll, and said lower die base is in transmission connection through key and lower roll.

Preferably, said upper die base and patrix briquetting are structure as a whole, and said lower die base and counterdie groove are structure as a whole.

The beneficial effect of the utility model does, said spheroid rolls mould, is equipped with four-roll plate bending machine, can process sphere part easily, and not only stock utilization is low, reduce production costs, and processing is simple, convenient, reduces labour intensity, has improved production efficiency.

The specific embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment.

Please referring to figs. 1 through shown in 4, in present embodiment, a kind of spheroid rolls mould; Comprise patrix 7 and counterdie 9, said patrix 7 is cylindric with counterdie 9 integral body, and said patrix 7 is made up of upper die base 1 and patrix briquetting 2; Said upper die base 1 is made up of symmetrically arranged left pedestal and right pedestal, and said patrix briquetting 2 is for having the projection of radian, and it circumferentially is arranged at upper die base 1 outer surface; Be structure as a whole with upper die base 1, be provided with screwed hole on the patrix briquetting 2 that the left pedestal of upper die base 1 and right pedestal outer surface circumferentially are provided with, and upper die base 1 be fixed in top roll 8 through bolt 3; And upper die base 1 is in transmission connection through key and top roll 8; Said counterdie 9 is made up of lower die base 4 and counterdie groove 5, and said lower die base 4 is made up of symmetrically arranged left pedestal and right pedestal, and it is cylindric that integral body is; Said counterdie groove 5 is the arc groove that is complementary with patrix briquetting 2; And it circumferentially is arranged at lower die base 4 outer surfaces, is structure as a whole with lower die base 4, is provided with screwed hole on the counterdie groove 5 that the left pedestal of lower die base 4 and right pedestal outer surface circumferentially are provided with; And through bolt 3 lower die base 4 is fixed in lower roll 10, and lower die base 4 is in transmission connection through key and lower roll 10.

As shown in Figure 5, during work, only need patrix 7 is fixedly installed in the top roll 8 of four-roll plate bending machine; And counterdie 9 is fixedly installed in the lower roll 10 of four-roll plate bending machine, and workpiece 6 is set in patrix 7, as shown in Figure 6; At this moment, under the driving that promotes oil cylinder, between workpiece 6 cards and patrix briquetting 2 and counterdie groove 5; Rotation through top roll 8 drives patrix 7 rotations, and drives workpiece 6 rotations, thereby realizes rolling of spheroid.Through the sphere part that this kind processing mode is produced, not only product qualified rate is high, and stock utilization is low, easy to process simple, reduced labour intensity, improved production efficiency.

Above embodiment has just set forth the basic principle and the characteristic of the utility model; The utility model is not limited by the foregoing description; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various variations and change, and these variations and change all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
