Description

Technical Field

[0001] This utility model provides a straightening machine, and particularly relates to a novel high-speed straightening machine for various wires. Background Technology

[0002] A wire straightening machine is a device used to straighten metal wires (such as steel bars and steel wires). Its core function is to eliminate the bending deformation of the wires during rolling, transportation or storage through mechanical action, so that they meet the required straightness requirements. It is widely used in construction, machinery manufacturing and other fields.

[0003] Traditional straightening machines typically consist of a wire feeding device, a straightening main unit, a shearing mechanism, and a storage device. The wire feeding device often uses a simple support frame to support the wire roll. The straightening main unit straightens the wire roll using a set of straightening rollers with a fixed rotation speed. The shearing mechanism relies on a mechanical clutch or hydraulic drive to achieve fixed-length cutting. The storage device is usually an open bracket or a short-distance conveyor. While this structure can perform basic straightening functions, it has significant drawbacks: First, the wire feeding device lacks sufficient support rigidity, causing the wire roll to sway and become unstable during high-speed feeding. Second, the rotation speed of the straightening rollers in the straightening main unit cannot be dynamically matched with the feeding speed, and manual clamping methods cannot guarantee constant pressure, leading to fluctuations in straightening accuracy. Third, the shearing mechanism has a delayed response and large inertial force, easily causing fixed-length errors. Fourth, the safety protection structure is rudimentary, lacking an effective flow channel, making the wire prone to deviation or even splashing during high-speed feeding. Fifth, the storage device has limited capacity and lacks an adjustable bracket, making it unable to adapt to the output and processing needs of wires of different specifications. Utility Model Content

[0004] In order to solve the above problems, this application provides a new type of high-speed straightening machine for various wires, which solves the defects of traditional straightening machines such as low efficiency, insufficient precision, unstable feeding, poor stability and low degree of automation, and improves the efficiency, accuracy and reliability of straightening operations.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel high-speed straightening machine for various wires, comprising the following components connected sequentially along the wire conveying direction:

[0006] The wire laying device consists of a rectangular frame base, a circular turntable mounted on the base, a central column vertically fixed to the center of the turntable, and diagonal bracing rods connecting the central column to the edge of the turntable.

[0007] Safety cage: It has a horn-shaped frame structure, with its large opening facing the wire feeding device and its small opening coaxially connected to the feed inlet of the straightening host.

[0008] The straightening unit has a rectangular box structure with ventilation windows on the side of the box.

[0009] Electrical control device: It is a vertical control cabinet with an operation display panel on the front and heat dissipation holes on both sides;

[0010] Material storage device: It is a long strip-shaped main frame, with multiple U-shaped brackets installed at intervals along the length of the main frame. The brackets are detachably connected to the main frame.

[0011] Preferably, the diameter of the circular turntable of the wire feeding device is 2.7m to 3.5m, and the rectangular frame base is a support structure formed by welding crisscrossing steel beams.

[0012] Preferably, the conical frame of the safety cage is composed of multiple inclined straight rods and annular crossbars welded together to form a flow channel with a gradually changing diameter.

[0013] Preferably, the top of the rectangular box of the straightening host has an inspection port, and the heat dissipation window is a louvered structure.

[0014] Preferably, the cabinet of the electronic control device has a height of 815mm and a width of 900mm, and a lockable closed cabinet door is provided at the lower front of the cabinet.

[0015] Preferably, the elongated main frame of the storage device has a length of 12230mm; the U-shaped bracket has an upward-facing opening and ear plates on both sides, which are bolted to the main frame.

[0016] Preferably, the main frame of the storage device consists of two parallel long beams and a support beam welded between the long beams at intervals, and the U-shaped bracket is installed on the upper surface of the long beams.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] This new high-speed straightening machine provides stable support for the wire coil through a wire feeding device (composed of a rectangular frame base, a circular turntable, a central column, and diagonal braces; the turntable diameter is 2.7m to 3.5m, and the base is welded with steel beams), optimizing the feeding foundation. A safety cage (a flared frame welded with multiple inclined straight bars and annular crossbars) forms a gradually changing diameter guide channel, guiding the wire coil stably into the straightening main unit and preventing deviation during high-speed feeding. The straightening main unit (a rectangular box with an inspection port on the top and louvered ventilation windows on the sides) works in conjunction with an electronic control device (815mm high, 9m wide). The 00mm vertical control cabinet integrates operation display and frequency conversion control (with a lockable cabinet door at the bottom). It replaces the original manual shifting with frequency conversion control to match the straightening roller speed with the feeding speed, replaces the original manual clamping with pneumatic clamping to ensure constant pressure, and replaces the original pneumatic clutch shearing with servo shearing to improve response accuracy. The material storage device (12230mm long, consisting of a main frame composed of parallel long beams and support beams, with U-shaped brackets screwed to both sides of the ear plates) orderly supports the straightened wire, ultimately achieving high-speed, high-precision, and high-stability wire straightening, overcoming the multi-dimensional defects of traditional equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figure 1 and Figure 2 As shown, the wire feeding device 1 of the straightening machine consists of a rectangular frame base, a circular turntable installed on the base, a vertical central column at the center of the turntable, and diagonal bracing rods connecting the column and the edge of the turntable. The diameter of the circular turntable is 2.7m to 3.5m. The rectangular frame base is formed by welding crisscrossing steel beams to form a support structure. The safety cage 2 is a trumpet-shaped frame, which is formed by welding multiple inclined straight rods and ring crossbars to form a gradually changing diameter guide channel. Its large opening end faces the wire feeding device 1, and its small opening end is coaxially connected to the feed port of the straightening host 3. The straightening host 3 has a rectangular box structure with an inspection port on the top and a louvered heat dissipation window on the side.

[0030] In this implementation scheme, the rectangular frame base of the wire feeding device 1 is formed by welding crisscrossing steel beams to create a stable support structure. Combined with a circular turntable with a diameter of 2.7m to 3.5m, a central column, and diagonal braces, it provides a stable foundation for placing the wire coils, preventing the wire conveying from swaying due to unstable support during wire feeding in traditional equipment. The safety cage 2 uses multiple inclined straight rods and annular crossbars welded into a trumpet-shaped frame. Its large opening end faces the wire feeding device 1, and its small opening end is coaxially connected to the feed inlet of the straightening host 3, forming a gradually changing diameter guide channel. It can guide the wire accurately into the straightening host 3, solving the problems of wire deviation and jamming when the traditional equipment feeds at high speed. The top of the rectangular box of the straightening host 3 has an inspection port for easy maintenance of internal components, and the side has a louvered heat dissipation window to dissipate working heat in time, avoiding the impact of equipment overheating on operational stability. Through the above structural combination, the overall feeding stability, guiding accuracy and equipment operation continuity during the wire straightening process are improved, and the problems of poor feeding, poor stability and inconvenient maintenance of traditional straightening machines are specifically improved.

[0031] like Figure 3 and Figure 4 As shown, the electrical control device 4 is a vertical control cabinet with an operation display panel on the front and heat dissipation holes on both sides. The cabinet is 815mm high and 900mm wide, and a lockable cabinet door is installed at the bottom of the front. The long strip-shaped main frame of the storage device 5 is 12230mm long and consists of two parallel long beams and support beams welded between the long beams. The U-shaped bracket with the opening facing upward is fixed to the upper surface of the long beams by bolts through the ear plates on both sides.

[0032] In this implementation scheme, the vertical control cabinet of the electrical control device 4 is equipped with an operation display panel on the front, which facilitates operators to accurately set and adjust the straightening parameters, replacing the traditional manual adjustment method, improving the degree of automation and solving the problems of low efficiency and poor parameter consistency; the heat dissipation holes on both sides can dissipate the working heat of the electrical components inside the cabinet in time, avoiding the impact of excessive temperature on control accuracy. Combined with the compact size of 815mm height and 900mm width, it saves installation space; the lockable cabinet door at the bottom of the front can protect the internal circuit components and prevent malfunctions caused by unauthorized operation or dust intrusion. The long strip-shaped main frame of the storage device 5 is 12230mm long, which can accommodate more straightened wire and solve the problem of insufficient storage capacity of traditional equipment. Two parallel long beams are welded to the support beam to form a stable load-bearing structure. The U-shaped bracket with the opening facing upward is fixed to the long beam by the ear plate and bolts, which not only ensures the stability of the bracket support, but also makes it easy to adjust the bracket spacing according to the wire specifications, avoids the messy stacking of straightened wire, and improves the efficiency of material discharge and sorting. Through the above structural combination, the problems of low automation, limited storage capacity and inconvenient material discharge and sorting of traditional straightening machines are specifically improved.

[0033] In use, this device requires the use of existing wire materials (such as coiled steel bars, threaded steel bars, and ordinary steel wires, with a diameter range of 6-16mm) as the processing object. An external 380V industrial power supply powers the electrical control device 4 and each drive motor. It also requires existing lubrication devices to periodically lubricate rotating components such as the straightening roller bearings and conveyor axles within the straightening host 3 (using lithium-based grease). Furthermore, it requires existing speed sensors (installed on the conveying path of the straightening host 3) to monitor the wire conveying speed in real time and provide feedback to the operation display panel of the electrical control device 4. The rectangular box of the straightening host 3 is welded from Q235 steel plate, the vertical control cabinet of the electrical control device 4 is formed by bending cold-rolled steel plate, the parallel long beams of the material storage device 5 are made of No. 16 I-beams, and the U-shaped bracket is forged and machined from No. 45 steel. Through the coordination of these existing technologies and materials, the various structures of this device work together to achieve high-speed, high-precision straightening operations.

[0034] Specifically, during the implementation of this solution, the rectangular frame base of the wire feeding device 1, the cuboid box of the straightening host 3, the vertical control cabinet of the electrical control device 4, and the parallel long beam of the material storage device 5 are fixed to the concrete foundation using expansion bolts, as is done in existing technology. Before installation, a level is used to calibrate the levelness of the upper surface of each device to ensure consistent height along the wire conveying direction. During the wiring stage, copper core cables (4mm² cross-sectional area) are used in existing technology. 2 Connect the contactor and frequency converter inside the electrical control device 4 to the drive motor of the straightening host 3, the servo shearing device motor, and the turntable drive motor of the wire feeding device 1. The cable needs to be threaded through a galvanized metal conduit and fixed in a ground cable tray. Before use, the operator needs to use a measuring tape to measure the diameter of the wire to be processed (such as 6mm diameter coiled steel wire or 16mm diameter threaded steel bar), input the corresponding parameters through the operation display panel of the electrical control device 4, and then manually insert the center hole of the wire coil into the center column of the wire feeding device 1, pulling the end of the wire according to... The wire passes through the guide channel of the safety cage 2 and the feed inlet of the straightening host 3. Before starting, use a wrench to check the tightness of the bolts connecting the U-shaped bracket and the long beam of the storage device 5. During operation, an emergency stop is achieved by using the emergency stop button (installed on the operation panel of the electrical control device 4 and the side of the straightening host 3). The straightness of the straightened wire is checked periodically using a vernier caliper. The dust in the heat dissipation holes of the electrical control device 4 is cleaned with a brush dipped in kerosene. Through the combination of the above-mentioned existing technical means, the standardization and stability of the device from installation to operation are ensured.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
