Description
Technical field
The present invention relates to steel handling process, more particularly to a kind of steel pipe for generating both ends of the surface and carrying below 0.5MM chamferings
Technique.
Background technology
Inside and outside chamfering requires that below 0.5MM steel pipe fitting uses cold-heading machining blanks straight tube on automobile shock at present, and face takes
Turning both ends of the surface and inside and outside chamfering, the outward appearance shaping of product need 2 manufacturing procedures, and respectively cold-heading process and face takes process.
Cold-heading process (shown in reference picture 1- Fig. 6), for continuous automatic processing mode, steel are processed by cold headers, are divided into 6
Step：Steel blank (reference picture 1)-front and rear end carries out shaping (reference picture 2)-front and rear end and beats positioning hole (reference picture
3)-front end face punching (reference picture 4)-rear end face beats uropore (reference picture 5)-de- waste material (reference picture 6), wherein front and rear end
The purpose for carrying out shaping is the oblique angle for taking prominent plane for the front and rear end of steel, and the angle at general oblique angle is 8-12 degree
Between, the purpose at the oblique angle with prominent plane is shaping for convenience, and it is for cold headers that positioning hole is beaten in front and rear end
Forward and backward punching it is accurate, carry out beating deep hole again by first making a call to a shallow positioning hole；And first punched from front end face again from rear end
Face is punched, then de- material again；Steel pipe caused by cold-heading process need in addition by face take turning front/rear end in process and
Inside and outside chamfering, it finally can just produce inside and outside below chamfering 0.5MM steel pipe.Cold-heading process processing efficiency hourly is 3000
Part, and face takes process processing efficiency hourly about 700, so it is to influence production efficiency that face, which takes process processing efficiency low,
Immediate cause, and face takes process turning waste material to be present, causes stock utilization to reduce, and greatly improves its production cost.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art with deficiency, there is provided one kind can the face of reducing take process, directly
The technique for connecting steel pipe of the cold headers generation both ends of the surface with below 0.5MM chamferings.
The purpose of the present invention is achieved through the following technical solutions：A kind of steel for generating both ends of the surface and carrying below 0.5MM chamferings
The technique of pipe, including the following step carried out by cold headers：
Step 1, blank steel are carried out with the steel that blank becomes a cylindrical shape；
Step 2, shaping is carried out to steel front and rear end makes the conical surface of prominent 8-12 degree gradients on steel both ends of the surface band；
Step 3, the center of the front and rear end of the steel in step 2 is carried out beating positioning hole；
Step 4, beat steel front end face preceding hole and the depth in preceding hole is exceeded more than half length of steel；
Step 5, beats steel rear end face uropore, and the diameter of uropore is as the diameter in the preceding hole, and
The waste material of cut-off is left between uropore and preceding hole；
Step 6, the waste material in step 5 is removed and forms steel pipe；
In the step 2, in addition to the second process, the conical surface of second process described in two of steel front and rear end
Carry out chamfering and take R6-R10 chamfering；Also include step 7 after the step 6, to before the steel pipe in step 6,
Rear end face is extruded, and is made front end face, rear end face while is pressed into plane, the chamfering less times greater than 0.5MM is squeezed, finally
Generate the steel pipe that both ends of the surface carry below 0.5MM chamferings.
The present invention is had the following advantages relative to prior art and effect：
Due to directly carrying out chamfering to the conical surface in the front end faces of steel, rear end face by cold headers and making the edge of the conical surface
R6-R10 chamfering is taken, so during front end face, rear end face beat positioning hole, the chamfering is advantageous to the flowing of material,
Chamfering forms radius less times greater than 0.5MM chamfering due to being pressurized, and finally increases a step：By cold headers fight each other preceding hole,
Steel pipe after uropore is extruded, and the chamfering is less than 0.5MM and is completed the purpose of the present invention：Reduce the need that face takes process
The step of wanting turning, because the step efficiency of turning is very low, so the present invention is directly operated by cold headers and substantially increases life
The efficiency of production.

Embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are unlimited
In this.
A kind of technique of steel pipe of generation both ends of the surface with below 0.5MM chamferings shown in reference picture 1- Fig. 8, including pass through
The following step that cold headers are carried out：
Step 1, blank steel are carried out with the steel that blank becomes a cylindrical shape, shown in reference picture 1；
Step 2, reference picture 2, shaping is carried out to steel front and rear end makes prominent 8-12 degree gradients on steel both ends of the surface band
The conical surface, the gradient of the present embodiment conical surface is 8 degree (its state is as shown in arrow 1 in Fig. 2 and arrows 2).The institute of reference picture 8
Show：This step also includes the second process, and second process is that two conical surfaces of steel front and rear end are carried out chamfering and made
R6-R10 chamfering on the marginal belt of the conical surface (its state is as shown in arrow 3 in Fig. 8 and arrow 4), it is therefore an objective to because in step 3
In, during carrying out beating positioning hole 5 to the front end faces of steel respectively and rear end face beats positioning hole 5, steel are squeezed, by
The steel of extruding can spread forward around hole or around uropore, and R6-R10 chamfering is advantageous to material on the marginal belt of the conical surface
Flowing, due to the flowing of material, R6-R10 chamfering is pressurized the chamfering to be formed less times greater than 0.5MM；
Step 3, reference picture 3, to the center of the front and rear end of the steel in step 2 beat positioning hole 5 and whole
Shape, the depth of the positioning hole 5 is shallower, and in the process, the purpose of positioning hole is easy for that rear process beats preceding hole or beat metapore can
To beat in the center of material；Because steel are squeezed, the R6-R10 of the second process shaping in step 2 chamfering quilt
Shaping turns into the chamfering less times greater than 0.5MM.
Step 4, reference picture 4, beat steel front end face preceding hole 6 and the depth in preceding hole 6 is exceeded more than half length of steel；
Step 5, reference picture 5, uropore 7 is beaten steel rear end face, and the diameter of uropore 7 and the diameter in the preceding hole 6 are big
It is small the same, and the waste material 8 of cut-off is left between uropore 7 and preceding hole 6；
Step 6, reference picture 6, the waste material 8 in step 5 is removed and forms steel pipe；
Step 7, reference picture 7, the front and rear end of steel pipe described in step 6 is extruded, make the middle part of the conical surface
Flatten, make front end face, rear end face while be pressed into plane, the chamfering less times greater than 0.5MM is squeezed, and ultimately generates two
End face carries the steel pipe of below 0.5MM chamferings.
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any Spirit Essences without departing from the present invention with made under principle change, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
