Abstract
The utility model discloses a tertiary hole flanging drift, including first order drift, second level drift and third level drift, first order drift, second level drift and third level drift from the top down set gradually, first order drift is for leading positive drift, the external diameter of second level drift is greater than the external diameter of first order drift, the external diameter of third level drift is greater than the external diameter of second level drift, first order drift, second level drift and third level drift set up for integrated into one piece, the outside of first order drift, second level drift and third level drift sets up for the slope, this tertiary hole flanging drift can one step of formula accomplish the hole flanging operation.
Description
Technical field
This utility model relates to a kind of three grades of hole flanging punchs.
Background technology
Hole flanging, it is for bore edges being translated into setting limit, they are different from punching, punching is a kind of stamping procedure separated along closed outline from material or process part processing by waste material, obtaining the hole of needs on material or process part processing, hole flanging is a kind of stamping procedure that material is translated into edge-on flange around endoporus.
Drift, the metal parts in diel in machine tool, is called again punching rod, red needle or punching pin, is mounted in diel and carries out continuous stamping punching press thrusts operation, machined material is made to occur to separate or plastic deformation, thus obtaining required finished product or semi-finished product.
Drift is also punch, upper mould, formpiston, red needle etc., and drift is divided into A type drift, T-shaped drift, special-shaped plunger chip; Drift is mounted in the metal parts in diel, is applied to contact with the direct of material, makes material deform upon, cuts material; Mold and punching head is generally adopted high-speed steel and wolfram steel etc. as material, there are high-speed steel drift and wolfram steel drift etc., and high-speed steel is the most frequently used material, conventional has CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., and wolfram steel material is commonly used in and requires on higher punching and shearing die.
Existing hole flanging punch has following defect:
1. hole flanging requires height, and height and wall thickness need more than 2 steps just can complete, and cause that die cost increases, and easily lacks material and cause product rejection burn failure in high-speed production, and production efficiency reduces;
2. the thickness of slab of portion of material is 1.2mm, and hole flanging requirement for height is at more than 2.54mm, and wall thickness requires to be 0.3mm, and existing drift one step is unable to reach requirement.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind of can complete three grades of hole flanging punchs of hole flanging operation by single step.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of three grades of hole flanging punchs, including first order drift, second level drift and third level drift, described first order drift, second level drift and third level drift set gradually from top to bottom, described first order drift is correcting drift, the external diameter of described second level drift is more than the external diameter of first order drift, the external diameter of described third level drift is more than the external diameter of second level drift, described first order drift, second level drift and third level drift are formed in one setting, and the outside of described first order drift, second level drift and third level drift is for being obliquely installed.
As preferably, the diameter of described first order drift is 2.85mm.
As preferably, the diameter of described second level drift is 4.3mm.
As preferably, the diameter of described third level drift is 4.82mm.
As preferably, the length of described first order drift is 3.51mm.
As preferably, the length of described second level drift is 5.69mm.
As preferably, the length of described third level drift is 5.2mm.
The beneficial effects of the utility model are: owing to being provided with first order drift, second level drift and third level drift, and the outside of described first order drift, second level drift and third level drift is for being obliquely installed, punching press can be sequentially carried out, the hole flanging that punching press produces is without two times punch, decrease damage of product rate, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of three grades of hole flanging punchs of this utility model.
Detailed description of the invention
For making architectural feature of the present utility model and effect of reaching are had a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, illustrate as follows:
As described in Figure 1, a kind of three grades of hole flanging punchs, including first order drift 1, second level drift 2 and third level drift 3, described first order drift 1, second level drift 2 and third level drift 3 set gradually from top to bottom, described first order drift 1 is correcting drift, the external diameter of described second level drift 2 is more than the external diameter of first order drift 1, the external diameter of described third level drift 3 is more than the external diameter of second level drift 2, described first order drift 1, second level drift 2 and third level drift 3 are formed in one setting, described first order drift 1, the outside of second level drift 2 and third level drift 3 is for being obliquely installed.
The diameter of described first order drift 1 is 2.85mm.
The diameter of described second level drift 2 is 4.3mm.
The diameter of described third level drift 3 is 4.82mm.
The length of described first order drift 1 is 3.51mm.
The length of described second level drift 2 is 5.69mm.
The length of described third level drift 3 is 5.2mm.
Workflow:
Drift makes three grades, one-level correcting, and two grades and three grades of hole flangings reach product requirement.
The beneficial effects of the utility model are: owing to being provided with first order drift, second level drift and third level drift, and the outside of described first order drift, second level drift and third level drift is for being obliquely installed, punching press can be sequentially carried out, the hole flanging that punching press produces is without two times punch, decrease damage of product rate, improve production efficiency.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.
