Description

Technical Field

[0001] This utility model relates to the field of galvanized iron wire processing technology, specifically a galvanized iron wire cutting machine. Background Technology

[0002] Galvanized iron wire is a metal wire made from ordinary iron wire as the base material, through hot-dip galvanizing (high-temperature immersion zinc) or electroplating (electrolytic zinc plating) processes to form a zinc protective layer on the surface. Utilizing the antioxidant properties of zinc, it isolates air and moisture, thereby significantly improving rust and corrosion resistance and extending service life. It is suitable for outdoor applications such as building reinforcement, fence weaving, agricultural greenhouses, and garden binding. Its silver-gray surface can be dyed or passivated as needed. Combining flexibility and tensile strength, it is a cost-effective anti-corrosion metal product.

[0003] Based on existing galvanized iron wire cutting machines, it has been found that due to insufficient mechanical structure design or transmission precision of the delivery device, intermittent pauses or speed fluctuations occur during wire delivery, leading to accumulated positional errors. This results in inconsistent cutting lengths due to synchronization control deviations during the cutting mechanism's operation, affecting the uniformity of wire dimensions in batch processing. Furthermore, the reliance on manual material handling poses a safety risk. Therefore, this invention designs a galvanized iron wire cutting machine to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a galvanized iron wire processing and cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A galvanized iron wire processing and cutting machine includes a worktable and an iron wire body. The worktable is provided with a continuous delivery mechanism and a cutting disc. The continuous delivery mechanism includes a ball screw, a stepper motor, a ball nut, and symmetrically distributed clamping components. The stepper motor is fixed to the upper end of the worktable, and its output end is connected to the ball screw. The ball nut is sleeved on the ball screw and fixed with a limit plate. The limit plate is slidably connected to a limit rail on the worktable. The clamping components include a first support rod, a second support rod, a third support rod, and a fourth support rod. Each support rod is fixed to the outer wall of the ball nut. The first and second support rods have a first driving air rod and a second driving air rod on their inner sides, and their transmission ends are respectively connected to a first clamping plate and a second clamping plate. The third and fourth support rods have a third driving air rod and a fourth driving air rod on their inner sides, and their transmission ends are respectively connected to a third clamping plate and a fourth clamping plate. The iron wire body passes through the limit sleeve and is located within the clamping range from the first clamping plate to the fourth clamping plate. The cutting disc is disposed above the interval area of ​​the clamping components and is connected to the drive motor through a transmission chamber.

[0007] Optionally, the first and second driving air rods are symmetrically distributed on the right side of the wire body, and the third and fourth driving air rods are symmetrically distributed on the left side of the wire body. The first, second, third, and fourth clamping plates constitute a four-sided synchronous clamping structure.

[0008] Optionally, the end of the ball screw is fixed to the worktable by a bearing bracket, and the limiting sleeve is coaxially aligned with the wire body.

[0009] Optionally, the transmission chamber is equipped with a transmission belt connecting the drive motor and the cutting disc. The lower end of the transmission chamber is hinged to the worktable via a bearing seat, and a hydraulic cylinder is hinged to its outer side. The other end of the hydraulic cylinder is hinged to the inner wall of the worktable.

[0010] Optionally, the first and second support rods constitute a right-side delivery clamping unit, and the third and fourth support rods constitute a left-side fixing clamping unit. The cutting plane of the cutting disc is perpendicular to the axis of the wire body and is located between the right-side delivery clamping unit and the left-side fixing clamping unit.

[0011] Optionally, the extension direction of the limiting slide rail is parallel to the axis of the ball screw, and its length covers the maximum stroke range of the ball nut.

[0012] Optionally, the telescopic movement of the hydraulic cylinder drives the transmission chamber to rotate around the bearing seat, causing the cutting disc to cut into or out of the wire body in a direction perpendicular to the worktable.

[0013] Optionally, the rotation of the stepper motor is converted into the linear motion of the ball nut through the ball screw, and the ball nut constrains the motion trajectory through the cooperation of the limiting plate and the limiting slide rail.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a continuous delivery mechanism is provided. Through the closed-loop cooperation of the ball screw and the stepper motor, combined with the rigid guidance of the ball nut by the limit slide rail, high-precision control of the delivery stroke is achieved. The four sets of pneumatic clamps (first clamp, second clamp, third clamp and fourth clamp) are connected in the alternating action of the left and right clamping units, which completely eliminates the intermittent stagnation caused by traditional single-point clamping. With the axial constraint of the limit sleeve, the wire can be continuously delivered and continuously cut.

[0016] 2. In this utility model, a cutting component is provided. The vertical cutting action of the cutting disc driven by the hydraulic cylinder is combined with the hinged flipping structure of the transmission chamber to ensure that the cutting plane is always orthogonal to the axis of the wire body. The modularly designed transmission chamber integrates the drive motor and the transmission belt, which reduces the vibration transmission during high-speed rotation. The cutting torque is optimized by the fulcrum layout of the bearing seat, which extends the blade life. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1-10 In this embodiment of the utility model, a galvanized iron wire processing and cutting machine includes a horizontally arranged worktable 1, on which a continuous delivery mechanism 3 and a cutting disc 4 are integrated, wherein:

[0032] The continuous delivery mechanism 3 is located in the middle section of the wire body 2 and is used to precisely control the delivery length of the wire body 2;

[0033] The cutting disc 4 is installed above the gap between the right delivery clamping unit and the left fixed clamping unit of the continuous delivery mechanism 3, and vertical cutting is achieved by hydraulic drive.

[0034] The continuous delivery mechanism 3 includes a ball screw 301, a stepper motor 302, a ball nut 303, and symmetrically distributed clamping assemblies.

[0035] The ball screw 301 is horizontally fixed to the upper surface of the worktable 1. One end of the ball screw is connected to the output shaft of the stepper motor 302 through a coupling, and the other end is fixed to the left end area of ​​the worktable 1 through a bearing bracket 318.

[0036] The ball nut 303 is sleeved on the ball screw 301, and a limit plate 316 is welded to its lower end. The bottom of the limit plate 316 is provided with a slider that matches the limit slide rail 317 on the worktable 1, so as to ensure that the ball nut 303 moves only in a straight line along the axis of the ball screw 301.

[0037] The clamping assembly consists of four support rods and a pneumatic clamping plate:

[0038] The first support rod 304 and the second support rod 307 are vertically welded to the front and rear sides of the ball nut 303. The first drive air rod 305 and the second drive air rod 308 are respectively installed on their inner sides. The piston rod end of the drive air rod is connected to the first clamping plate 306 and the second clamping plate 309. The two clamping plates are arranged opposite to each other to form the right-side delivery clamping unit.

[0039] The third support rod 310 and the fourth support rod 313 are vertically welded to the left and right sides of the ball nut 303. The third drive air rod 311 and the fourth drive air rod 314 are installed on their inner sides. The piston rod ends are connected to the third clamping plate 312 and the fourth clamping plate 315. The two clamping plates are arranged opposite each other to form the left side fixed clamping unit.

[0040] The limiting sleeve 319 is fixed to the feed end of the workbench 1, and its inner hole is coaxial with the wire body 2, which is used to guide the wire body 2 into the clamping area.

[0041] The cutting assembly includes a cutting disc 4, a transmission chamber 5, a drive motor 7, and a hydraulic cylinder 8.

[0042] The transmission chamber 5 is a closed cavity, with its lower end hinged to the surface of the worktable 1 via a bearing seat 9, and the upper end equipped with a cutting disc 4.

[0043] The drive motor 7 is fixed to the right side of the transmission chamber 5, and its output shaft is connected to the central rotating shaft of the cutting disc 4 via the transmission belt 6.

[0044] The cylinder body of the hydraulic cylinder 8 is hinged to the inner wall of the workbench 1, and the piston rod is hinged to the outer wall of the transmission chamber 5. The extension and retraction of the hydraulic cylinder 8 drives the transmission chamber 5 to rotate around the bearing seat 9, thereby causing the cutting disc 4 to cut into or out of the wire body 2 in a direction perpendicular to the workbench 1.

[0045] The working principle of this utility model is as follows: Before activation, all driving components inside the machine body need to be powered on and connected to the control terminal. The driving air rods in the continuous delivery mechanism 3 also need to be connected to an external cylinder to ensure control effectiveness. Upon activation, the wire 2 is first passed through the limiting sleeve 319 and positioned directly below the cutting disc 4. Before cutting, the continuous delivery mechanism 3 needs to be activated. Air is supplied through the external cylinder, and the first driving air rod 305, second driving air rod 308, third driving air rod 311, and fourth driving air rod 314 within the continuous delivery mechanism 3 are activated to fix and clamp the wire 2. At this time, the hydraulic cylinder 8 is activated to flip the cutting disc 4, using the cutting disc 4 to cut the wire 2. After the cutting operation is completed, the continuous delivery mechanism 3 is activated again. The stepper motor 302 within the continuous delivery mechanism 3 drives the ball screw 301 to rotate, thereby driving the ball screw... The four sets of drive air rods on the mother 303 and ball nut 303, including the wire 2, move from left to right, moving a certain distance (this distance needs to be preset by the stepper motor 302, through the ball transmission structure, which is the length of the cut wire). Then, the external cylinder supplying air pressure is turned off. At this time, the wire 2 cut for the first time will fall. Then, the stepper motor 302 in the continuous delivery mechanism 3 is started to drive the ball screw 301 to rotate in the opposite direction, thereby driving the ball nut 303 and the four sets of drive air rods on the ball nut 303 to move from left to right again, moving to below the cutting disc 4. At this time, the wire 2 is clamped again by the continuous delivery mechanism 3, and the second cutting operation of the wire 2 can be performed. According to the above operation, the wire 2 can be cut continuously, and the length of the wire 2 can also be accurately cut with the help of the ball transmission assembly.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
