Abstract
The invention discloses a vehicle seat framework preparation method; a seat framework is provided with a positioning bottom hole, at least 98 mounting holes, a round hole arranged on an arc surface of the seat framework, and circumference holes arranged on the peripheral of the seat framework; the method comprises the following steps: stretching; punching the positioning bottom hole; punching the mounting holes; punching the round hole; punching the circumference holes. Before the stretching step, the blank material of the seat framework is wrapped by a plastic film. The advantages are that the method can effectively ensure the product to have good quality.
Description
Technical field
The present invention relates to technical field of automobile, especially relate to a kind of preparation method of automobile chair frame.
Background technology
The quality of automobile chair frame quality, directly affects comfort level when passenger takes.But, at present when preparing automobile chair frame, there is the quality that following problem affects product then: 1, in stretching process, product surface is easy to wrinkling more; 2, the location in each hole is inaccurate; 3, the opportunity in each hole of punching press is reasonable not, then add the operation that some are unnecessary, and more operation directly causes the reduction of product quality; When 4, being in the circular hole on arcwall face in punching press, very easily make it to become elliptical aperture; 5, often position is accurate to be not positioned at the punching of surrounding.
Summary of the invention
The object of this invention is to provide a kind of preparation method of automobile chair frame, it has effectively can ensure that product has the feature of preferable quality.
The technical solution adopted in the present invention is: the preparation method of automobile chair frame, this chair framework has location bottom outlet, at least 98 pilot holes, the circular hole be positioned on the arcwall face of this chair framework, be positioned at the circumferential apertures of chair framework surrounding, this preparation method includes the operation in stretching, punching press location bottom outlet, punching press pilot hole, punching press circular hole, punching press surrounding hole, in described stretching process, before stretching, on the blank of this chair framework, wrap up layer of plastic film.
After the operation of described punching press location bottom outlet is positioned at stretching process, be positioned at other all process steps before.
The operation of described punching press pilot hole is in a procedure.
Oval drift is adopted in the operation of described punching press circular hole.
Adopt in the operation in described punching press surrounding hole and fold wedge standard component.
The present invention is compared to the prior art advantageously: can effectively ensure that product has preferable quality.The preparation method of automobile chair frame of the present invention eliminated by coated film the wrinkling problem of product surface, by rationally determine the priority of operation ensure that location accurate, by ensure that the opportunity of reasonable arrangement punching operation minimizing, by adopting oval drift ensure that, circular hole can not be out of shape, ensure that the accurate of surrounding punching by employing standard component.In a word, by eliminating common product defects, ensure that product has preferable quality.
Detailed description of the invention
Embodiment, the preparation method of automobile chair frame, this chair framework has location bottom outlet, at least 98 pilot holes, the circular hole be positioned on the arcwall face of this chair framework, is positioned at the circumferential apertures of chair framework surrounding.The preparation method of this automobile chair frame improves based on any common preparation method, thus this preparation method includes the operation in stretching, punching press location bottom outlet, punching press pilot hole, punching press circular hole, punching press surrounding hole.Concretely, in stretching process, before stretching, on the blank of this chair framework, wrap up layer of plastic film.The thickness of this plastic sheeting between 0.5 ~ 1mm, can be not limited only to this certainly, adopts the difference of the plastic sheeting of different-thickness to be only the ability height of smoothing wrinkle.Through inventor's actual verification, adopt after the method, the problem that when effectively eliminating stretching, piece surface is easily wrinkling.
Continue to optimize:
This punching press location bottom outlet operation be positioned at stretching process after, be positioned at other all process steps before.Other operations so-called, comprise the operations such as aforementioned punching press pilot hole, punching press circular hole, punching press surrounding hole.Like this, by made location bottom outlet in advance, effectively ensure that position degree.
The operation of this punching press pilot hole is in a procedure.A so-called procedure, refers in the process of those pilot holes of punching press, does not carry out any other operation.Like this, effectively reduce unnecessary operation, make production efficiency higher, and product quality is guaranteed.
Oval drift is adopted to give punching press in the operation of this punching press circular hole.Like this, ensure that the hole gone out is for circular.
Adopt in the operation in this punching press surrounding hole and fold wedge standard component.Like this, by guaranteeing that mould has preferably stability, effectively ensure that position degree.
In sum, the preparation method of automobile chair frame of the present invention eliminates common product defects, ensure that product has preferable quality.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
