Description

Technical Field

[0001] The present invention relates to an integrated pulley preparation device, in particular to a multi-wire cutting integrated pulley preparation device and a preparation method thereof, belonging to the integrated pulley preparation technical field. Background Art

[0002] Multi-wire cutting machine technology is used in the silicon processing industry and the solar photovoltaic industry. The multi-wire cutting integrated pulley is a component used to feed steel wires on the multi-wire cutting machine. The existing multi-wire cutting integrated pulley structure consists of a polymer outer groove ring and an inner hub.

[0003] When preparing the existing wire-cut integrated pulley, first use an injection molding machine to form an inner hub and an ungrooved outer groove ring (at this time, the inner ring of the outer groove ring also has grooves, which is injection molding), and then use a manual splicing method to combine the inner hub and the ungrooved outer groove ring. First, put the outer groove ring into a heating device (similar to a thermal expansion machine) to soften the outer groove ring (to make it plastic), and then use a manual socketing method to fit the inner hub with the softened outer groove ring. Then, put the assembled pulley into a cold shrinking device for cooling. Due to the principle of thermal expansion and contraction, the outer groove ring is fixed to the inner hub to form a pulley. Then, the pulley is slotted and trimmed.

[0004] During the use of the above-mentioned preparation equipment, manual splicing may cause the inner hub to deform due to pressing with both hands. Because the inner hub is also a plastic product with a certain plasticity, there is a problem of extrusion deformation, which may lead to scrap. Secondly, due to the thermal expansion and contraction method adopted, the outer groove ring will shrink and squeeze the inner hub during shrinkage, which may also lead to extrusion deformation and scrap. At the same time, after the existing preparation equipment is injection-molded for the integrated pulley, the integrated pulley adheres to the inside of the molding groove and is difficult to remove. During the removal process, it is also easy to cause damage to the integrated pulley. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-wire cutting integrated pulley preparation equipment and a preparation and processing method thereof, which can solve the problem that the existing integrated pulley preparation equipment cannot stably connect the outer groove ring and the inner hub during the production process, which easily causes deformation when the outer groove ring and the inner hub are connected, resulting in material scrap.

Second, deformation rarely occurs, and the efficiency is improved. In addition, this injection molding is carried out because mold injection is used, so there is almost no thermal expansion and contraction, and no gaps will appear.

[0054] S5. The water in the cooling water tank 430 enters the water inlet pipe 420 under the action of the water pump 431. The cooling water in the water inlet pipe 420 enters the cooling water pipe 440. The cooling water pipe 440 is located inside the lower mold base 200 and below the molding groove 210. When the cooling water flows through the cooling water pipe 440, it can take away the heat dissipated by the injection molded part, which is conducive to the rapid molding of the inner wheel hub. The cooling water that has taken away the temperature returns to the cooling water tank 430 through the return pipe 410, so that water resources are reused repeatedly and water waste is avoided.

[0055] S6. After the inner hub is formed, the upper die seat 300 moves upward and disengages from the pressing block 620 and the pressing strip 621. The movable plate 630 returns to its original position under the action of the return spring 633 and the connecting rod 631. The movable plate 630 drives the demoulding rod 611 and the demoulding module 610 to move upward, ejecting the outer groove ring and the inner hub inside the molding groove 210, so that the outer groove ring and the inner hub can be demoulded quickly, preventing the newly formed outer groove ring and the inner hub from being damaged and destroyed during manual demoulding.

[0056] S7. The outer groove ring and inner hub are injection molded as one body, and are grooved by a grooving tool. During grooving, since both sides of the outer groove ring are embedded in the inner hub, the inner hub serves as the support surface of the outer groove ring. During cutting, there is almost no vibration mark, so there is almost no poor appearance. During operation, due to the improvement of the above-mentioned processing technology and structure, during operation, both sides of the outer groove ring are embedded in the inner hub, so the inner hub serves as the support surface of the outer groove ring, so the steel wire is almost not broken. In addition, the reduction in product weight realizes the reduction of inertia, so the shutdown and wire breakage are almost not likely to occur.

[0057] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0058] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
