Description

Technical Field

[0001] This utility model relates to the field of copper wire drawing technology, specifically to an inverted wire drawing machine peeling mold holder. Background Technology

[0002] In the field of copper wire drawing, the precise removal of the oxide layer and defect layer on the surface of the copper wire is the core link to ensure the conductivity, mechanical strength and subsequent processing quality of the wire.

[0003] Currently, the industry generally adopts a mechanical scraping process using a stripping die. This process uses the squeezing or cutting action of a hard alloy die inside a fixed stripping die box to peel off impurities from the surface of the copper wire layer by layer. However, traditional equipment has significant design flaws: metal shavings, powders, and other impurities generated during the stripping process will directly fall into the lubricating oil in the oil pan. The oil pan is usually a static open structure and lacks an effective solid-liquid separation mechanism. As production time increases, the concentration of impurities in the lubricating oil increases, leading to increased oil viscosity and decreased lubrication performance. This, in turn, causes problems such as scratches on the surface of the copper wire and increased die wear, requiring the machine to be stopped for manual cleaning. To address this, we propose an inverted stripping die holder for wire drawing machines. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached document Figure 1-3 An inverted wire drawing machine peeling die holder includes an oil pan 1, which is a rectangular groove structure containing an appropriate amount of lubricating oil. A wire feeding device 2 for copper wires to pass through is provided on one side of the oil pan 1. The wire feeding device 2 is equipped with a ceramic guide sleeve for the copper wires to pass through and to prevent the copper wires from deviating.

[0024] The oil pan 1 is equipped with a support base 3 inside. The support base 3 is equipped with several stripping mold box devices 4 arranged along the copper wire passing direction of the wire feeding device 2. The stripping mold box devices 4 at both ends are used to guide the copper wire. The inner cavity of the several stripping mold box devices 4 in the middle is equipped with a stripping mold to remove impurities on the surface of the wire, such as oxide layer or defect layer, by mechanical extrusion or cutting. The bottom of the oil pan 1 is equipped with a chip outlet 6 for collecting the removed impurities on the surface of the wire.

[0025] Among them, the design of several peeling mold cavities with decreasing inner diameters enables progressive peeling, ensuring the accuracy of surface treatment.

[0026] In this embodiment, the support base 3 is provided with a number of guide wheels 5, which are distributed among a number of stripping mold box devices 4. Each guide wheel 5 has a V-shaped groove on its outer wall, with the groove depth exceeding 1 / 3 of the copper wire diameter, for supporting and conveying the copper wire.

[0027] In this embodiment, the bottom of the tail end of the oil pan 1 is provided with an oil return pipe 7. The oil return pipe 7 adopts a 1.5-inch water return pipe interface. The oil return pipe 7 is connected to a circulation pump, which is used to draw the lubricating oil cooled at the rear end of the oil pan 1 to the top of the front end of the inner cavity of the oil pan 1 and spray it onto the copper wire between the front stripping mold box device 4 and the wire inlet device 2 to lubricate the copper wire and prevent the copper wire from being damaged.

[0028] In this embodiment, a baffle plate is provided inside the oil pan 1. The height of the baffle plate is higher than the height of the lubricating oil in the oil pan 1. The baffle plate is a rectangular closed structure with its bottom edge fixed to the ground inside the oil pan 1. Its planar layout completely surrounds the vertical projection of the middle peeling mold box device 4 and the upper entrance area of ​​the chip discharge port 6. By setting the baffle plate, the lubricating oil in the oil pan 1 can be prevented from flowing out through the chip discharge port 6, while the impurities peeled off by the middle peeling mold box device 4 can be collected.

[0029] In this embodiment, the bottom of the oil pan 1 is provided with a mold base 8. One side of the top of the mold base 8 is rotatably connected to the bottom of the oil pan 1 via a pin 10. The top of the mold base 8 away from the pin 10 is provided with a threaded sleeve 11. An adjusting bolt 12 is threadedly connected to the threaded sleeve 11. The top of the adjusting bolt 12 abuts against the bottom of the oil pan 1. When the adjusting bolt 12 is rotated, it moves up and down within the threaded sleeve 11. At this time, the oil pan 1 will rotate around the axis of the pin 10, changing its tilt angle. This facilitates the leveling operation of the oil pan 1 and also facilitates the discharge of lubricating oil from the oil pan 1.

[0030] In this embodiment, the top of the mold base 8 is provided with a receiving interface 9, which is set corresponding to the chip outlet 6 and is used to collect impurities falling through the chip outlet 6. The size of the receiving interface 9 is larger than the size of the chip outlet 6, which can ensure that the impurities falling through the chip outlet 6 are completely collected. The mold base 8 is provided with a guide plate 13 inside. The guide plate 13 is inclined and located below the receiving interface 9. The falling impurities are guided to a designated position through the guide plate 13 for easy subsequent collection.

[0031] Working principle: During operation, the copper wire passes through the inlet device 2 and then sequentially through the stripping mold box device 4 arranged along the direction of copper wire travel on the support base 3.

[0032] The stripping molds at both ends serve as guides, while the stripping molds in the middle mold remove the oxide layer and defect layer on the surface of the copper wire step by step through mechanical extrusion or cutting.

[0033] The removed impurities fall through the chip discharge port 6. The barrier plate, being higher than the lubricating oil level and completely surrounding the area above the chip discharge port 6, can prevent the lubricating oil from flowing out and guide the impurities to fall into the lower receiving port 9.

[0034] Through the return oil pipe 7 and the circulation pump, the lubricating oil cooled at the tail end of the oil pan 1 is drawn to the front end and sprayed onto the copper wire between the stripping mold box device 4 and the wire inlet device 2 to form a continuous lubricating film, reduce the coefficient of friction, and prevent the copper wire from being pulled.

[0035] The mold base 8 is rotatably connected to the oil pan 1 via the pin 10. Rotating the adjusting bolt 12 can change the tilt angle of the oil pan 1, which is convenient for leveling operations and can also accelerate the discharge of lubricating oil and impurities through gravity. The guide plate 13 is tilted below the receiving interface 9 to guide impurities to the designated collection position for easy subsequent cleaning.
