Hot-forming line discharging table double-centering system

Abstract

The invention discloses a hot-forming line discharging table double-centering system. The double-centering system comprises a plurality of first centering fingers and a plurality of second centering fingers, the first centering fingers and the second centering fingers are correspondingly arranged in rows on the left side and the right side of a furnace roller frame, the double-centering system further comprises at least one third centering finger and at least one fourth centering finger arranged between the first centering fingers and the second centering fingers, the third centering finger and the fourth centering finger are correspondingly arranged at the positions, near the left and the right, of the middle part of the furnace roller frame, the first, second, third and fourth centeringfingers are correspondingly arranged between transmission rollers, and the first, second, third and fourth centering fingers move left and right under the action of corresponding driving air cylinders. According to the hot-forming line discharging table double-centering system, the structure is simple, operation is convenient and fast, fast positioning of multiple material sheets can be simultaneously achieved, and the problem that multi-cavity short material sheets can not be simultaneously produced is solved; for material sheet products with complex shapes, more choices of the centering fingers are provided during debugging; the centering fingers are driven by adopting the air cylinder, positions can be adjusted manually after closing air source, and debugging is convenient.

Description

technical field [0001] The invention relates to a double-centering system for a discharge table of a thermoforming line, which belongs to the technical field of thermoforming. Background technique [0002] Thermoforming technology is an emerging technology that originated in the 1980s. It is an innovative and future-oriented part forming technology solution for the automotive industry to reduce the weight of the car body without losing safety in order to achieve the purpose of energy saving and emission reduction. . With the continuous improvement of energy saving and emission reduction requirements, thermoformed parts will be more and more widely used in auto parts. [0003] In the existing production process of thermoformed parts, the blank is heated to about 930°C in the heating furnace, and is quickly transported out of the furnace by the roller table. The sheet is lifted up, and the end picker grabs the material and sends it to the mold for pressing and forming. After...

Problems solved by technology

[0004] The centering system of the discharge table directly determines the product processing range of the thermoforming line. At present, the centering system of the discharge table of the thermoforming line mostly uses a single-row centering finger structure on the discharge table to complete the positioning of a sheet. At least three middle fingers are required in the middle, and a single row of middle fingers cannot meet the production of multi-cavity short blanks such as one mold with three cavities and one mold with four cavities.

[0005] A temporary measure to solve the above problems is to produce multi-cavity products in one mold in separate cavities. One punch only presses two sheets, which not only reduces production efficiency but also increases production costs. Therefore, a fast, accurate and simultaneous positioning of short multi-cavity materials is needed. Sheet thermoforming line discharge table double centering system
