Abstract

The utility model relates to a sample pipe bending mold. Two through holes are formed in a base, fixing bolts penetrate through the through holes in the base and then are connected with a bending mold I and a bending mold II respectively, and both the bending mold I and the bending mold II are formed by a plurality of discs in an coaxial mode, wherein the diameters of the discs are reduced gradually. According to the sample pipe bending mold, through combination of molds of different sizes, guiding pipe production can meet the digital bending condition when sample pipes are bent according to the sizes of the molds.

Description

Sample pipe bending mould

Technical field

The utility model relates to a kind of guiding-tube bend mould, the especially a kind of bending mould that can accurately control sample pipe bending radius.

Background technology

The profile of many conduits need to be according to perimeter mounted state in-situ determination in the time of assembling.And comparatively difficulty of large-size pipe manual bending, shape should not be got system at the scene, the profile trends that use the undersized aluminum pipes such as φ 6mm to get the required conduit of system for sample pipe in practical operation more, identical with the centre line shape of required pipe because of sample pipe, can produce with sample pipe profile the conduit that meets matching requirements.When conduit batch production, adopt numerical-control bending, its bending radius need to meet some requirements more, but the manual sample pipe of system of getting, bending radius only depends on workman visual definite, is difficult to meet conduit numerical-control bending condition, cannot will reduce production efficiency and conduit manufacture accuracy by numerical-control bending.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of sample pipe bending mould, and by the combination of different size mould, after can ensureing according to the bending sample pipe of die size, conduit is produced and met digitlization bending condition.

For solving above technical problem, concrete technical scheme of the present utility model is as follows: a kind of sample pipe bending mould, and base is provided with two through holes, and set bolt is connected with bending die I, bending die II respectively after running through the through hole of base; Described bending die I and bending die II are respectively coaxial setting of disk that several diameters successively decrease gradually and form.

Disk diameter in described bending die I increases progressively from the bottom to top gradually, and the disk diameter in bending die II successively decreases from the bottom to top gradually.

In described bending die I and bending die II, the excircle of each disk is marked with size.

This sample pipe bending mould adopts said structure, only need can be met by the bending sample pipe of mould tire the conduit of numerical-control bending requirement, is ensureing, under the prerequisite of bending diameter, to have improved operating efficiency.

Bending die is marked with size, conveniently selects suitable bending die according to the specification of required conduit, can ensure the dimensional accuracy of required conduit.

Brief description of the drawings

Fig. 1 is the front view of sample pipe bending mould.

Fig. 2 is the use state diagram of sample pipe bending mould.

Specific embodiment

As depicted in figs. 1 and 2, a kind of sample pipe bending mould, base 1 is provided with two through holes, and set bolt 4 is connected with bending die I 2, bending die II 3 respectively after running through the through hole of base 1; Described bending die I 2 and bending die II 3 are respectively coaxial setting of disk that several diameters successively decrease gradually and form.

Disk diameter in described bending die I 2 increases progressively from the bottom to top gradually, and the disk diameter in bending die II 3 successively decreases from the bottom to top gradually.

In described bending die I 2 and bending die II 3, the excircle of each disk is marked with size.

The utility model concrete operation step is as follows:

1. base 1 is fixed on vice;

2. select suitable bending die 2,3 according to the specification of required conduit and bending radius;

3. by the brake forming on the bending mould choosing of sample pipe;

4. use numerically controlled measuring machine to measure sample pipe;

5. the data that use numerically controlled measuring machine to record bend required conduit.
