Description

Technical Field

[0001] This utility model relates to the field of metal wire processing technology, specifically a wire clamping device for a wire drawing machine. Background Technology

[0002] During the operation of a wire drawing machine, especially when the winding device is fully wound or stops due to a malfunction, a wire clamping device has emerged and plays a crucial role in preventing the metal wire from becoming loose, tangled, or even damaging the equipment due to loss of tension control.

[0003] Existing wire clamping devices for wire drawing machines often have complex structural designs, employing multiple sets of clamping blocks of different specifications and requiring cumbersome switching devices. This necessitates frequent replacement of clamping blocks or adjustment of the clamping block spacing, making the operation extremely inconvenient and prone to errors that can affect the clamping effect and production efficiency. Therefore, it is essential to design a wire clamping device for wire drawing machines that is structurally simplified and highly efficient and reliable. Utility Model Content

[0004] The purpose of this invention is to provide a wire clamping device for a wire drawing machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wire clamping device for a wire drawing machine, including a chuck seat, a chuck seat cover plate provided on the chuck seat, a plurality of corresponding first through holes provided on the chuck seat and the chuck seat cover plate, a hexagonal screw connected to the plurality of first through holes, the hexagonal screw including a nut and a screw rod, an installation cavity provided between the chuck seat and the chuck seat cover plate, an eccentric wheel provided inside the installation cavity, a corresponding second through hole provided between the eccentric wheel and the chuck seat cover plate, a chuck seat pin movably connected to the second through hole, the chuck seat pin including a seat pin head and a pin shaft, and a spring washer provided below the seat pin head and the nut.

[0006] According to the above technical solution, at least two mounting holes are also provided on one side of the chuck seat, and hexagonal screws are connected to the mounting holes.

[0007] According to the above technical solution, a sealing adhesive layer is provided between the chuck seat and the chuck seat cover plate.

[0009] According to the above technical solution, the outer surfaces of the chuck seat and the chuck seat cover are both coated with an insulating coating.

[0010] According to the above technical solution, a diameter measuring sensor is installed inside the eccentric wheel.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By setting an eccentric structure with an eccentric wheel and a diameter sensor, the operator can accurately adjust the rotation angle of the eccentric wheel according to the wire diameter data provided by the diameter sensor, thereby accurately changing the contact position and pressure relationship between the eccentric wheel and the wire. Since the eccentric wheel can be flexibly adjusted, the device can effectively adapt to wires of different diameters, thereby improving the versatility and adaptability of the wire clamping device and reducing the tedious operation of changing different wire clamping devices due to changes in wire diameter.

[0013] (2) By setting up a chuck seat, a chuck seat cover plate, a hexagonal screw, a spring washer, an eccentric wheel and a chuck seat pin, a simple and compact wire clamping device is formed. Compared with some complex wire clamping structures, this device does not have too many redundant parts and complex transmission structures.

[0018] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] Please see Figure 1-2The present invention provides a technical solution: a wire clamping device for a wire drawing machine, comprising a chuck seat 1, a chuck seat cover plate 11 on the chuck seat 1, a plurality of corresponding first through holes on the chuck seat 1 and the chuck seat cover plate 11, a plurality of hexagonal screws connected to the plurality of first through holes, the hexagonal screws comprising a nut 2 and a screw rod, an installation cavity 3 provided between the chuck seat 1 and the chuck seat cover plate 11, an eccentric wheel 31 provided inside the installation cavity 3, a corresponding second through hole provided between the eccentric wheel 31 and the chuck seat cover plate 11, a chuck seat pin movably connected to the second through hole, the chuck seat pin comprising a seat pin head 4 and a pin shaft, and a spring washer 5 provided below both the seat pin head 4 and the nut 2.

[0020] This technical solution utilizes hexagonal screws and spring washers 5 to tightly connect the chuck seat 1 and the chuck seat cover plate 11 through the first through hole. The spring washers 5 effectively prevent the hexagonal screws from loosening due to machine vibration, ensuring the stability of the connection structure between the chuck seat and the chuck seat cover plate, and providing a solid foundation for the entire wire clamping device. The eccentric wheel mounting cavity 3 on the chuck seat 1 provides installation space for the eccentric wheel 31. The eccentric wheel 31 is movably connected to the chuck seat cover plate 11 through the chuck seat pin, and the spring washer 5 below the pin head 4 plays a role in buffering and auxiliary stabilization, allowing the eccentric wheel 31 to rotate flexibly around the chuck seat pin. In turn, its eccentric structure changes the clamping force on the metal wire placed between the chuck seat 1 and the eccentric wheel 31, achieving precise clamping of metal wires of different specifications. This meets the wire clamping needs of the wire drawing machine in various metal wire processing scenarios and ensures the efficient and stable operation of the wire drawing process.

[0021] Furthermore, at least two mounting holes are provided on one side of the chuck seat 1, and hexagonal screws are connected to the mounting holes;

[0022] This technical solution enhances the stability of the connection between the chuck seat 1 and the equipment, thereby avoiding problems such as displacement and shaking of the wire clamping device due to an unstable connection.

[0023] Furthermore, a sealing layer is provided between the chuck seat 1 and the chuck seat cover plate 11;

[0024] This technical solution effectively fills the tiny gap between the chuck seat 1 and the chuck seat cover 11, preventing metal impurities from entering the wire clamping device.

[0025] Furthermore, the eccentric wheel 31 is made of alloy steel;

[0026] With this technical solution, the eccentric wheel 31 is less prone to deformation and wear, reducing the frequency of replacement of the eccentric wheel 31 due to material wear.

[0027] Furthermore, both the outer surfaces of the chuck seat 1 and the chuck seat cover plate 11 are coated with an insulating coating;

[0028] This technical solution effectively prevents current from being conducted to the operator, thus preventing the generation and accumulation of static electricity.

[0029] Furthermore, a diameter measuring sensor is installed inside the eccentric wheel 31;

[0030] This technical solution allows for rapid and accurate measurement of the wire's diameter the instant it enters the clamping area. The diameter data is then transmitted to the control system, enabling operators to precisely adjust the rotation angle of the eccentric wheel 31 based on the diameter data, thus preventing damage to the wire due to excessive clamping force.

[0031] Working principle: The chuck seat 1 and the chuck seat cover 11 are tightly connected by hexagonal screws and spring washers 5. The spring washers 5 provide a continuous elastic preload for the connection structure, effectively preventing the hexagonal screws from loosening due to vibration and other factors during device operation. Meanwhile, the sealing layer between the chuck seat 1 and the chuck seat cover 11 acts as a seal to prevent external dust and processing impurities from entering the interior. When the metal wire is introduced into the wire clamping device and placed at the predetermined position between the eccentric wheel 31 and the chuck seat 1, the diameter sensor measures the diameter information of the metal wire and immediately transmits the data to the control system. The operator adjusts the rotation angle of the eccentric wheel 31 based on the obtained metal wire diameter data. When the eccentric wheel 31 rotates, its eccentric structure causes the contact part with the metal wire to change displacement, thereby accurately adjusting the clamping pressure on the metal wire and ensuring that the metal wire does not slip during the wire drawing process. Furthermore, if the equipment experiences a sudden situation, such as a sudden power outage, interruption of power transmission, or encountering a strong external impact, the eccentric wheel 31 can still maintain the clamping state of the metal wire, thereby reducing the risk of production interruption and metal wire loss caused by sudden situations and ensuring the continuity and stability of the wire drawing production process.
