Abstract
The invention discloses a steel pipe bending forming die. The steel pipe bending forming die comprises an upper die base and a lower die base. The upper die base is provided with an upper die plate, and the lower die base is provided with a lower die plate. Each of the upper die plate and the lower die plate is composed of two side plates. The upper die plate is internally provided with an upper die core, and the lower die plate is internally provided with a lower die core. A steel pipe is placed between the upper die core and the lower die core. The opposite faces of the upper die core and the lower die core serve as forming faces which are curved faces. The curved faces correspond to the target bending degree of the steel pipe. According to the steel pipe bending forming die, the cost input is low, operation is easy, and the strength of the die is sufficient; and according to the requirements for the product length, the oil press tonnage and the product size, the work efficiency and the bending quality can be greatly improved, and the labor intensity is reduced.
Description
Technical field：
The present invention relates to mould applications, a kind of particularly tube bending shaping mould.
Background technology：
The pipe fitting bending of some bendings is cumbersome, and existing die mould mode is line（N bar line）Divide N-1 section die mould, accessory size is difficult to ensure that, higher to operative employee's skill set requirements, and the cycle of pressure one is long, after pressure, R dimensional uniformity is bad, steel pipe periphery impression seriously needs polishing, Puttying, has a strong impact on presentation quality after paint.
Using existing bend pipe machine equipment, design pushes away curved mould, and method is feasible, but hydraulic press die mould technique is changed to push-bending process, and mould input cost is very big, pushes away curved mould fabrication cycle long.
Design the regular press-moulding die with impression orbit using hydraulic press, this method is feasible but die mould bounce-back empirical value does not know, and a whole set of frock making cycle is long, and the qualified risk of die trial is big.
Content of the invention：
The invention aims to solution the deficiencies in the prior art, there is provided a kind of tube bending shaping mould.
The technical solution used in the present invention is：
Tube bending shaping mould, including upper and lower die holder it is characterised in that：
It is respectively equipped with upper and lower template on described upper and lower die holder, upper and lower template is constituted by biside plate, it is respectively equipped with upper and lower core rod in upper and lower template, placing steel tubes between upper and lower core rod, the relative face of upper and lower core rod is as forming surface, forming surface is curved surface, and curved surface is correspondingly arranged with the target flexural degree of steel pipe.
Described tube bending shaping mould it is characterised in that：
The described contact surface of upper and lower template and the forming surface of core rod are arranged concentrically.
Described tube bending shaping mould it is characterised in that：
It is equipped with mounting groove on described upper and lower die holder, and be provided with reinforcement between upper and lower die holder and upper and lower template.
Compared with prior art, the beneficial effects of the present invention is：
Cost input of the present invention is little, simple to operate, and the intensity of mould enough, under requiring according to product length, hydraulic press tonnage, product size, can be greatly improved work efficiency and bending quality, reduce labor intensity.
Brief description：
Fig. 1 is the perspective view of the present invention；
Fig. 2 is the front view structure figure of the present invention.
Specific embodiment：
Below in conjunction with the accompanying drawings, by embodiment, the present invention is described in further detail：
Tube bending shaping mould, including upper and lower die holder 1,2, upper and lower template 3,4 is respectively equipped with upper and lower die holder 1,2, upper and lower template 3,4 is constituted by biside plate, it is respectively equipped with upper and lower core rod 5,6, placing steel tubes 7 between upper and lower core rod 5,6, the relative face of upper and lower core rod 5,6 is as forming surface in upper and lower template 3,4, forming surface is curved surface, and curved surface is correspondingly arranged with the target flexural degree of steel pipe 7.
The contact surface of upper and lower template 3,4 is all arranged concentrically with the forming surface of upper and lower core rod 5,6.
It is equipped with mounting groove 8 on upper and lower die holder 1,2, and be provided with reinforcement 9 between upper and lower die holder 1,2 and upper and lower template 3,4.
Above-described embodiment is only the preferably embodiment of the present invention, and in addition, the present invention can also have other implementations.It should be noted that on the premise of without departing from present inventive concept, any conspicuously improved and modification all should fall under the scope of the present invention.
