Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel rolling equipment, especially an improved wire collecting device for reducing head scratches of wire coils during the collecting process. The device is suitable for modern steel rolling production lines and aims to improve wire product quality and yield while reducing equipment maintenance costs. BACKGROUND

[0002] In modern steel production, wire manufacturing typically involves processes such as continuous casting, hot rolling, or cold rolling, ultimately forming wire products of different specifications. To facilitate transportation and storage, these wires need to be collected and packaged into coil form. Currently, the commonly used wire collecting equipment in China mainly includes Danieli, Morgan, SMS, Sendzimir, and several other structural types, each with its own characteristics and technical advantages.

[0003] Although the above-mentioned types of collecting equipment are widely used in the market and each has certain advanced nature, there are still some common problems in actual use, especially when handling the head of the wire coil, which is prone to scratches. Since the scratched part does not meet the quality standards, it must be trimmed, which causes material waste and reduces the yield. Specifically:

[0004] The existing wire collecting equipment generally uses a multi-claw connecting rod mechanism as a temporary coil supporting arm to support the wire coil being formed. When the wire coil accumulates to a certain height, the temporary coil supporting arm releases the wire coil from below, allowing it to fall onto the lifting coil supporting plate by its own gravity. However, two major problems arise during this process:

[0005] Drop impact: After the lifting coil supporting plate is raised into position, there is still a certain distance between it and the temporary coil supporting arm, which means that the wire coil will have a certain falling distance when it is detached from the temporary coil supporting arm. The impact force generated by this free fall can damage the lifting coil supporting plate, which may cause equipment failure over time, increasing maintenance frequency and cost. At the same time, the falling process can also cause irreversible damage to the wire coil itself, such as deformation, cracking, etc., thereby affecting product quality.

[0006] Head scratches: When the temporary coil supporting arm is opened, the bottom of the wire coil will rub against the surface of the coil supporting arm due to the instantaneous loss of support, especially at high speeds. This friction easily causes scratches on the head of the wire coil. Even a slight scratch can make the part of the wire not meet customer requirements and must be trimmed. According to statistics, this part of the loss can account for several percent of the total output, seriously affecting the economic benefits of the enterprise.

[0007] In view of the above problems, there is an urgent need for a novel design that can effectively solve the problem of wire roll head scratches and drop impact. The ideal solution should be able to protect the wire roll from additional physical damage without affecting the existing production process, while minimizing material loss and improving product market competitiveness. Practical new content

[0008] In order to make up for the above shortcomings, the utility model provides a kind of wire rod collection device for reducing the scratch of wire roll head.

[0009] The utility model is realized through the following technical schemes: a kind of wire rod collection device for reducing the scratch of wire roll head, including collection reel, nose cone, temporary roll supporting arm, lifting roll supporting plate and mandrel, its technical key points are: lifting support for supporting wire roll is provided on lifting roll supporting plate;Lifting support is provided with the notch of collection reel in the lower part of collection reel to avoid the interference between collection reel and lifting support;Height corresponding to lifting support is provided with high support in the lower part of mandrel;Lifting support is fixedly connected with lifting roll supporting plate by inserting plate pin;High support is fixedly connected with mandrel by inserting plate pin;Inserting plate pin is provided with pinhole for inserting plate to pass through.

[0010] Further, the number of lifting supports is four, which are distributed circumferentially.

[0011] Further, the number of high supports is four, which are distributed circumferentially.

[0012] Further, the notch of collection reel is provided with an inclined cutout, and the connection between the inclined cutout and the notch of collection reel is a rounded corner.

[0013] The utility model has the advantages of:

[0014] Eliminate drop impact and prevent head scratches: by introducing lifting support structure, wire roll can be properly lifted before it is separated from temporary roll supporting arm, eliminating the process of wire roll falling to lifting roll supporting plate, thereby reducing the risk of equipment damage; At the same time, through the lifting of support structure, wire roll is separated from temporary roll supporting arm before temporary roll supporting arm is opened, which eliminates the possibility of head scratches and reduces unnecessary pruning amount.

[0015] Easy to install and disassemble: considering the diversity and complexity of actual production, the utility model adopts inserting plate pin connection mode, which allows users to quickly install or disassemble related components according to needs, improving the flexibility and adaptability of equipment.

[0023] Preferably, the number of lifting supports is four, which are distributed circumferentially.

[0024] Preferably, the number of heightening supports is four, which are distributed circumferentially.

[0025] In order to reduce the area of gather reel notch, and prevent wire reel from being damaged after expanding out of gather reel and rubbing against the edge of gather reel notch, a bevel is provided at the gather reel notch, and the connection between the bevel and the gather reel notch is a round angle.

[0026] The following will be combined with Figures 1-4The content of the utility model is illustrated in detail through specific embodiments. Embodiments

[0027] Basic structure and working principle:

[0028] 1. Structure composition

[0029] Collecting reel 1: used for accommodating the forming wire coil, the lower part of which is provided with a collecting reel notch 101 to avoid interference with the lifting support. In order to further reduce the friction between the wire coil and the collecting reel, a bevel cut 102 is designed at the notch, and a round corner transition 103 is used at the connection of the bevel cut and the collecting reel notch to prevent the edge of the wire coil from being damaged after expansion.

[0030] Nose cone 2: located inside the collecting reel, used as a guide component for the wire entering the collecting reel, to ensure that the wire can be evenly distributed in the entire annular gap and form a regular wire coil.

[0031] Temporary coil supporting arm 3: a multi-claw linkage mechanism, responsible for supporting the forming wire coil until the set height or weight is reached. When the wire coil is ready to be transferred, the temporary coil supporting arm will automatically open and release the wire coil.

[0032] Lifting coil supporting plate 4: located below the collecting reel, used to receive the wire coil separated from the temporary coil supporting arm. Four circumferentially distributed lifting supports 401 are provided on it, which can be fixedly connected with the lifting coil supporting plate through the plug pin 403. Each lifting support is equipped with a plug 404, and quick installation or disassembly is realized through the pin hole 405.

[0033] Core rod 5: located below the lifting coil supporting plate, used to finally receive and support the wire coil that has completed the winding. The lower part of the core rod is also provided with four circumferentially distributed heightening supports 501, which are also fixedly connected with the core rod through plug pins, to ensure the height matching with the lifting supports, so that the wire coil can be smoothly transferred to the core rod.

[0034] 2. Working principle

[0035] In the wire production process, the scattered coils are sequentially dropped on the temporary coil supporting arms by falling, and gradually accumulate to form wire coils. At this time, the wire coils are stably supported by the temporary coil supporting arms, and the lifting coil supporting plate is in a low position waiting to receive the wire coils. When the wire coils reach the predetermined height or weight, the control system issues a command to start the lifting support. The lifting support moves upward and gently lifts the wire coils a distance, ensuring that the bottom of the wire coils is no longer in contact with the temporary coil supporting arms, thereby avoiding the risk of head scratches. At this time, the wire coils have been completely supported by the lifting support and no longer rely on the temporary coil supporting arms. Next, the temporary coil supporting arms start to open under the action of the control system. Since the wire coils have been stably supported by the lifting support, they will not fall or sway due to the opening of the temporary coil supporting arms, eliminating the possibility of falling impact. Then, the lifting coil supporting plate slowly descends to place the wire coils on the heightening support, completing the entire transfer process. Finally, the coil transport trolley lifts the wire coils on the rotating mandrel and suspends them on the C-shaped hook, completing the collection.

[0036] The key improvement points of the utility model are:

[0037] The role of the lifting support: by lifting the wire coils in advance, it avoids the falling of the wire coils due to their own weight when the temporary coil supporting arms open, solving the problem of friction and scratches that may occur between the wire coils and the temporary coil supporting arms in traditional designs.

[0038] Seamless docking mechanism: the height matching design of the lifting support and the heightening support ensures that the wire coils can smoothly transition from the lifting support to the heightening support, with no obvious gaps or steps in the entire process, further reducing potential damage to the wire coils.

[0039] Safety and reliability: the quick installation / dismounting design of the plug-in plate pin and the plug-in plate not only improves the flexibility of the equipment, but also enhances the safety and reliability of the system, making it easier to maintain and adjust.

[0040] Through the above improvements, the utility model effectively solves the problems of falling impact and head scratches in the prior art, significantly improves the quality and yield of wire products, and reduces the maintenance cost of the equipment.
