Problems solved by technology

When designing and drawing the mouth plate, the staff needs to calculate a large amount of data. The tedious and boring calculation process leads to low calculation and drawing efficiency of the designer, high error rate, low production efficiency, and affects the quality of the tire tread.
In addition, a large number of repeated calculations and drawings also limit the development of model design.

Embodiment 1

[0037] like Figure 1-Figure 3 Shown, a kind of tire tread outlet mold plate drawing method based on Excel and CAD platform of the present invention may further comprise the steps:

[0038] (1) Create an excel file, input the required tread information parameters, and compile the excel function formula;

[0039] In the above excel sheet, select and fill in the required rubber number, mold line, thickness of glue at the edge of the pre-die, pre-die and die plate number in the orange text box. The molding line, the thickness of the glue at the edge of the pre-cut, the pre-cut shape and the number of the die plate correspond to the corresponding opening coefficients entered in the excel table in order to facilitate the subsequent data calculation; after that, fill in the tread size of the cut-out plate According to the tread size, the data of the mouth plate is calculated through the excel function formula and the corresponding plate opening coefficient table, and the relationsh...

Embodiment 2

[0058] On the basis of Embodiment 1, in the excel file, the connection between the button and the CAD is programmed through the VB program, so that clicking the button can directly link the opened CAD and create a new drawing.

[0059] Furthermore, you can choose a drawing with a frame that has been set in CAD in advance. Through the VB program, in the header of the drawing, fill in the specifications, patterns, grades and other information filled in the excel file into the legend in the lower right corner of the drawing with a frame.

[0060] Furthermore, in the excel file, the VB programming button is connected with excel, the save button is set, and the filled data is filled in the table of the exported data according to the corresponding format, so as to facilitate later data access and create Excel database.

Embodiment 3

[0062] On the basis of embodiment 1, judge according to the parameters and control parameters in the excel file, judge whether the control parameters meet the drawing requirements, if the control parameters are all, then draw, if some parameters are missing, a warning is given, and the missing parameters are proposed.

Abstract

The invention discloses a tire tread mold plate drawing method based on Excel and a CAD platform, and the method comprises the following steps: (1) creating an excel file, inputting required tire tread information parameters, and compiling an excel function formula; (2) driving CAD to draw a graph through a VB program; and (3) exporting required tread information data in the excel file through a VB program, and establishing an excel platform database according to the exported tread information data. The method has the beneficial effects that a designer is in one-key butt joint with a drawn graph according to input tire tread information data; inputting the tread information data into a'one-key mapping 'mode; the method has the advantages that the change of the mouth shape plate is responded quickly, the complete mouth shape plate design drawing is drawn automatically, the tread information data is calculated through the function formula, the calculation error appearing in manual calculation is effectively reduced, the workload of drawing and modifying the drawing is reduced, the design period is greatly shortened, and the mouth shape plate drawing and designing efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, in particular to a method for drawing a tire tread outlet die plate based on Excel and a CAD platform. Background technique [0002] Tires are an important guarantee for automobile safety. How to make tires have better balance performance and wear resistance is a concern of tire manufacturers. The tread is an important component of the tire, and the quality of the tread is inseparable from the performance of the tire. Molding is one of the most important steps in the tire production process, and it is also the top priority in tire production material preparation. The quality of the shape directly affects the quality of the tire tread. When producing treads of different specifications, it is necessary to replace the supporting die plate at the same time, so the design and drawing of the die plate directly affect the production of tires. When designing and drawing the mouth plate, the...
