Abstract
Disclosed are a blank of an automotive front pillar inner plate part and a machining method. The blank is integrally similar to the appearance of the front pillar inner plate part, the middle of the blank is straight, one end of the blank is wide, the other end of the blank is narrow, two ends of the blank are bent towards the same side, bent positions are in arc transition, the blank comprises two pieces distributed on an online blanking and machining structure unit, and the two pieces of the blank are in central symmetry. The machining method includes the steps: using two stamping dies with cavities in central symmetry for online blanking on an uncoiling blanking line; uncoiling a steel plate coil, and leading the steel plate coil to correspond to one blanking and machining structure unit when conveying the steel plate coil by the length of a blanking unit; and using an online process for blanking once to manufacture the two pieces of the steel plate blank of the front pillar inner plate, wherein the two pieces are arrayed in central symmetry. By the aid of the front pillar inner blank with the structure, material utilization rate can be increased, and cost can be reduced. Besides, the step of single blanking for rectangular blanks in subsequent machining is omitted, manufacturing procedures can be simplified, cost can be saved, control links are decreased, and precision and quality of final parts are improved.
Description
Technical field
The present invention relates to automobile front column inner panel steel plate blank and processing method.
Background technology
Along with the development of automobile industry and the contradiction of natural resources finiteness become increasingly conspicuous, people more and more pay attention to the auto parts stock utilization, improve stock utilization and have become reducing cost of automobile industry, promote the important means of energy-conserving and environment-protective.
The expansion significant surface 1 of common front column inner panel part is the strip polygon, and two long limits are parallel up and down, the equal downwarping in the left and right sides.Of Fig. 2, the steel plate blank of common automobile front column inner panel is a rectangle material 2, during finished parts; Horizontal the cutting of coil of strip obtained the rectangle material one by one, be washed into required automobile front column inner panel part with punch die through monomer blanking operation and essence then, the technical problem of its existence is: the steel plate blank is a rectangle; Need remove unnecessary material when forming part; The waste material that produces is many, and stock utilization is low, and cost is higher.Simultaneously, need be with first horizontal the cutting from the coil of strip of rectangle material, monomer blanking and essence are dashed then, process required part, and the operation of manufacturing approach is more when using the rectangle material, and cost is also higher.
Summary of the invention
The technical problem that the present invention will solve provides the blank and the processing method of a kind of economical with materials, lower-cost automobile front column inner panel part.
For solving the problems of the technologies described above, the structure of the steel plate blank of the front column inner panel of the present invention's design is following:
Said blank is characterized in that: the profile of global approximation front column inner panel part; The stage casing is straight, and an end is wide, and the other end is narrow; And two ends are crooked towards the same side; Crooked position adopts arc transition, and per two said blanks are staggered positioned opposite in an online blanking processing structure unit, promptly mutual center symmetric arrays.
Take the steel plate blank of the front column inner panel of said structure, because approximate required front column inner panel shape face is compared with the rectangular steel plates blank of existing front column inner panel; The waste material that final formation front column inner panel part produces is less; Thereby, can improve stock utilization, reduce cost.
The technical problem that the present invention also will solve provides a kind of processing method of simple above-mentioned automobile front column inner panel steel plate blank; It is to carry out online blanking with the punch die with an online blanking processing structure unit die cavity; The steel plate coiled strip launches the also length of a blanking unit of every transmission; Promptly corresponding blanking processing structure unit, online press carries out blanking one time, processes the steel plate blank of the front column inner panel of two mutual center symmetric arrays.
Adopt through above-mentioned automobile front column inner panel steel plate blank finished parts method; Compare through rectangle material manufacturing approach with existing; Saved following process and rectangular billet carried out the step of monomer blanking; Can practice thrift manufacturing process and cost, reduce controlling unit, improve final part precision and quality.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
As shown in Figure 3, the shape and structure of blanks is based on the features of shape of front column inner panel part in this front column, for improving stock utilization; It is designed to the polygonal shape blank 3 that edge and part are more pressed close to; The stage casing of this polygonal shape blank 3 is straight, and an end is wide, and the other end is narrow; Left and right two ends are crooked towards the same side, and crooked position 4 adopts arc transition, and sharp corner stress is concentrated when avoiding following process.
As shown in Figure 4, than the rectangular configuration blank, this polygonal shape blank 3 more is close to front column inner panel part 1 and launches significant surface, has improved the stock utilization of part, has reduced the waste material generation.
Referring to Fig. 5; The mode of processing this blank is on uncoiling blanking line, to carry out online blanking with two punch dies with symmetrical die cavity; The steel plate coiled strip launches the length of a blanking unit of every transmission; Promptly corresponding blanking processing structure unit, online press carries out blanking one time, processes the steel plate blank of two mutual center symmetric arrays front column inner panels.Promptly this blank distributes two on an online blanking processing structure unit, and two blank right ends stagger and relatively.
Referring to Fig. 6, contrast each the blanking unit of this blank and the material use situation of traditional rectangular material, the material area that the present invention can save each blanking unit is regional A shown in Figure 6.
Referring to Fig. 7, the coiled strip on the uncoiling blanking line launches the length L of a blanking unit of every transmission, and online press carries out blanking one time, processes i.e. two these blanks in a blanking unit.During punch process part of the present invention, can no longer carry out the operation of monomer blanking, simplify technology, reduce controlling unit, improve final part precision and quality when reducing cost.
