Car first template exemplar shaping method

Abstract

The invention provides an automobile hand plate sample forming method. The invention is characterized in that the invention comprises the steps of a. blank is obtained firstly to form a workpiece which is processed in order to form the back surface of the sample; b. a plurality of formed T-shaped round piles are bonded in a processing forming area; the T-shaped round pipe vertical end is bonded with the forming area of roughcast; the upper end surface of a horizontal part is corresponding to the back surface of the roughcast; c. the residual area of process forming is filled with gypsum which is levelly scraped; d. the frontage of the roughcast is processed after the gypsum is formed; e. the T-shaped round pile and the gypsum are removed. The invention bonds the T-shaped round pile to the back surface in the processing area of the workpiece by utilizing melted AB glue, thus improving bonding performance, fills and scraps the gypsum and then processes the frontage after forming; when the frontage is processed, because of the firm supporting of the T-shaped round pile, when the hand plate roughcast vibrates as subject to a cuter, the invention improves the supporting strength of the plate and effectively improves the deformation and cracking phenomenon appearing in the processing process of thin hand pate caused when the gypsum is loosened as subject to force.

Description

【Technical field】 [0001] The invention relates to a hand-board processing method, in particular to a hand-board sample forming method applied to the production of large-scale thin-walled hand-board trial samples for automobiles. 【Background technique】 [0002] Prototype, also known as "first board", refers to the first prototype of a product. Because the early prototypes were mainly made by hand, they are commonly called "handboards". Simply put, a prototype is a sample of a product made according to the drawings or data provided by the designer before the regular mold is opened. [0003] Prototypes were initially used to test the perfection and realization of product appearance, structure, craftsmanship, etc. The prototype industry in mainland China started when Hong Kong businessmen established the first prototype factory in Shenzhen in 1989. Difficult prototype. With the intensification of market competition, the product market life cycle is short, and the realistic ma...

AI Technical Summary

Problems solved by technology

However, when processing large thin-walled board parts, such as hand board parts with a length of more than 600mm and a thickness of less than 2-3mm, the blank is filled with gypsum, and the distance between the cutter and the gypsum layer is too close, causing the gypsum layer to vibrate and crack, which affects the processing of hand board parts. The support strength is so high that under the extreme pressure of the tool, the prototype parts will be deformed and torn due to insufficient support strength.
