Problems solved by technology

However, the aluminum pattern blocks are not evenly cut, and the fan-shaped angle 1 of each pattern block is different, varying between 30-65 degrees
When cutting, the angle bisector of the angle between the vertical seams of two adjacent pattern blocks is used as the cutting line (such as image 3 As shown), the angle bisector 4 of the vertical seam of blocks B and C formed between the vertical seam 2 of block B and the vertical seam 3 of block C is used as the cutting line, so that the cutting angle of the cutting line of each pattern block on the strip aluminum plate is Each is different, which has a great impact on the production efficiency of the scribing and sawing process of the aluminum pattern block blank on the strip aluminum plate; in addition, if Figure 4 As shown, when such a plate is clamped and cut, it is necessary to add an adjustment block 6 between the clamp pad iron 7 and the plate to match the position of the saw blade of the cutting saw, and a lot of cutting alignment time is wasted during cutting, resulting in a lower production efficiency. Low

Embodiment 1

[0051] Scribing tools for cutting tire mold blocks, such as Figure 7 Shown, including:

[0052] Ruler 12;

[0053] The ruler board 11 is set in the middle of the upper surface of the ruler base 12, and a right-angle step is left between the bottom of the ruler board 11 and the upper surface of the ruler base 12 for clamping the board at the step so that the board is attached to the ruler board 11;

[0054] The angle formed by the oblique side of the ruler board 11 and the bottom of the ruler board 11 is 90°-360° / 2n, n≥6.

[0055] Through the setting of the marking tool, it is convenient to find the cutting line of the pattern block on the plate, which is simple and convenient.

[0056] The scribing tool is provided with double-sided right-angle steps. When scribing the cutting line of a block, the scribing tool can turn the scribing tool along the length of the plate to realize the cutting line on both sides of a block. Delineation.

[0057] In order to simplify the structure, the rule...

Embodiment 2

[0059] In view of the various disadvantages caused by different cutting lines to the marking and cutting process, the angle of the block cutting line is unified to facilitate the marking and cutting process of the block cutting line and improve the processing efficiency. To shorten the processing cycle and reduce the production cost of mold parts.

[0060] Tire molds have different specifications, and the number of segments of the pattern block is also different, mostly 8, 9, 10 segments. Now take the 8-petal block as an example to improve the cutting line angle of the unified block and analyze and compare the processing conditions in the marking and cutting procedures.

[0061] 1. 8-petal blocks, the fan-shaped included angle varies from 40 degrees to 50 degrees. Under the premise of ensuring the vertical seam processing allowance and leaving the cutting opening, the angle of the cutting line is uniformly adjusted to 22.5° (half of 45°) with the center line of the pattern block (...

Abstract

The invention discloses a tire mold pattern block feeding cutting method and a marking tool. By unifying the angles of pattern block cutting lines, cutting is conducted after marking on boards. The marking tool is used for cutting line marking on boards. The included angle between a hypotenuse of the marking tool and the straight line on which the bottom of a board rule is located is 90-360 degrees / 2<n>, wherein n is larger than or equal to 6, n is the number of pattern block sections. Marking of follow-up cutting lines and center lines is effectively guaranteed, the marking efficiency and accuracy are improved, and the working efficiency of the marking procedure is increased by approximately 20%; due to the determination by the marking tool, point number determination for pattern block cutting lines is simplified, marking is simple, the production efficiency is effectively increased, and meanwhile, the arrangement of adjusting cushion blocks in a traditional method is avoided.

Description

Technical field [0001] The invention relates to a tire mold, in particular to a method for blanking and cutting tire mold pattern blocks. Background technique [0002] The part of the tire's active mold cavity is in the shape of a circle, which is formed by circular arrangement and assembly of multiple sector-shaped pattern blocks (such as figure 1 (Shown), these fan-shaped blocks are blanks cut from plates, and then the upper and lower sides of the aluminum plate are processed into the shape and inner cavity of the block respectively. According to the different specifications of tire molds, the number of lobes of the pattern blocks of a mold is also different, and the number is mostly 8, 9, 10 lobes. The fan-shaped included angle of each block must be set according to the shape of the mold pattern, so that the combined block can form a complete cavity without defects. [0003] Because aluminum blocks are cut according to the tire pattern, in order to ensure the integrity of the p...
