Description

Technical Field

[0001] This utility model relates to the field of wire drawing die technology, and in particular to a self-lubricating wire drawing die. Background Technology

[0002] Wire drawing dies are tools used in metal pressure processing to force metal through a die under external force, compressing the metal's cross-sectional area and obtaining the required cross-sectional shape and size. Before entering the die, the metal wire needs to be coated with drawing powder, also known as dry wire drawing lubricant. This process lubrication material forms a lubricating film between the drawn metal and the die wall, reducing friction between the interfaces, preventing metal from sticking to the die wall due to heat, thus reducing energy consumption and temperature rise during drawing, extending the die's service life, ensuring product surface quality, and making deformation uniform.

[0003] However, in existing mold drawing processes, the metal wire is passed through a drawing powder box to allow the drawing powder to adhere to the metal wire. Due to insufficient adhesion of the drawing powder, it is easy to fall off during the process. When the product is drawn later, there is less drawing powder on its surface, which cannot play a good lubricating role and cannot effectively reduce the coefficient of friction between the product and the cone hole wall of the deformed cone. Utility Model Content

[0004] This invention provides a self-lubricating wire drawing die, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A self-lubricating wire drawing die, comprising: The mold body has an inner cavity in the center, which is connected in sequence to the inlet area, compression area, sizing area and outlet area. The storage bin is installed on the side of the entrance area of ​​the mold body, and a through hole is provided in the middle of the storage bin; Multiple baffles are installed at equal angles in the inner cavity of the storage box along the through holes, and mounting shafts are rotatably installed on two adjacent baffles. Multiple conveyor components are coaxially fixedly installed on multiple mounting shafts, and multiple groove holes are provided on the conveyor components at equal angles; Two seals are installed at both ends of multiple baffles, and the conveyor is slidably connected to the baffle grooves of the seals. Furthermore, the storage bin includes: The box has an addition tube at the top and an outlet tube at the bottom. The sealing cap is threaded onto the outlet tube; Add a funnel, which is then attached to the adding tube.

[0006] Furthermore, the box body is provided with an extension, which is fixedly installed to the mold body by bolts.

[0007] Furthermore, a heat insulation layer is installed between the mold body and the box body.

[0008] Furthermore, the middle of the conveyor is provided with an arc-shaped structure with the same diameter as the metal wire.

[0009] Furthermore, chamfers are provided at both ends of the conveying component, and the chamfers are slidably connected to the baffles at both ends.

[0010] Furthermore, the edges of the seal are designed with an angled structure.

[0011] Furthermore, a drain port is provided on the mold body.

[0012] The following technical effects can be achieved through the technical solution of this utility model: The mold body provides a stable and continuous forming channel for metal wire drawing. The storage box, as a storage container for built-in drawing powder, is installed on the inlet side of the mold body. The through hole facilitates the passage of metal wire. Multiple baffles installed at equal angles along the through hole of the storage box provide a stable rotating mounting base for the mounting shaft. The multiple mounting shafts provide coaxial fixed support for the corresponding conveying components. The grooves on the multiple conveying components, which are coaxially fixed to the mounting shafts, carry the drawing powder from the storage box in a metered manner during rotation, and deliver the drawing powder to the metal wire, so that the metal wire is lubricated before entering the compression zone. This effectively avoids scratches on the wire surface or wear of the mold cavity caused by uneven lubrication. The seals installed at both ends of the baffles have their baffle grooves slidably connected to the conveying components to prevent the drawing powder in the storage box from leaking out of the gaps and causing waste. This achieves self-lubrication in the drawing process and reduces operating costs. Attached Figure Description

[0017] This application provides a self-lubricating wire drawing die, comprising: The mold body 1 has an inner cavity in the center, and the inner cavity is connected in sequence to the inlet area, the compression area, the sizing area and the outlet area; Storage box 2 is a storage container for wire drawing powder, which is installed on the inlet area side of mold body 1. A through hole is provided in the middle of storage box 2. Multiple baffles 3 are installed at equal angles in the inner cavity of the storage box 2 along the through hole of the storage box 2, and mounting shafts 4 are rotatably installed on two adjacent baffles 3; Multiple conveying components 5 are coaxially fixedly installed on multiple mounting shafts 4, and multiple groove holes are provided on the conveying components 5 at equal angles; Two seals 6 are respectively installed at both ends of multiple baffles 3, and the conveying component 5 is slidably connected to the baffle groove of the seal 6: Through the technical solution of this utility model, the mold body 1 provides a stable and continuous forming channel for metal wire drawing. The storage box 2, as a storage container for built-in drawing powder, is installed on the entrance area side of the mold body 1. The through hole facilitates the passage of metal wire. Multiple baffles 3 installed at equal angles along the through hole of the storage box 2 provide a stable rotating mounting base for the mounting shaft 4. The multiple mounting shafts 4 provide coaxial fixed support for the corresponding conveying components 5. The multiple conveying components 5, coaxially fixed on the mounting shaft 4, have grooves that quantitatively carry the drawing powder in the storage box 2 when rotating, and convey the drawing powder to the metal wire, so that the metal wire is lubricated before entering the compression zone. This effectively avoids scratches on the wire surface or wear of the mold cavity caused by uneven lubrication. The sealing components 6 installed at both ends of the baffles 3 have baffle grooves that are slidably connected to the conveying components 5 to prevent the drawing powder in the storage box 2 from leaking out of the gap and causing waste. This achieves self-lubrication in the drawing process and reduces operating costs.

[0018] During use, storage bin 2 includes: The box body 21 has an addition tube 22 at the top and an outlet tube 23 at the bottom; The sealing cap 24 is threadedly installed onto the outlet tube 23; Add funnel 25, which is installed on adding tube 22; Through the technical solution of this utility model, the box body 21 of the storage box 2 serves as the core storage carrier for drawing powder, continuously providing sufficient drawing powder for the drawing operation of the mold body 1. The addition tube 22 set at the top of the box body 21 provides a dedicated channel for replenishing drawing powder. In conjunction with the addition funnel 25 installed on the addition tube 22, the coverage range of the drawing powder addition opening is expanded, making it convenient for workers to quickly replenish drawing powder. The outlet tube 23 set at the bottom of the box body 21 facilitates the complete removal of residual drawing powder in the box when changing the type of drawing powder or periodically cleaning the storage box 2. The sealing cap 24, which is threaded onto the outlet tube 23, tightly seals the outlet tube 23 during normal use of the storage box 2, preventing the drawing powder in the box body 21 from leaking out from the bottom, thus improving the ease of use of the self-lubricating drawing mold.

[0019] In the above embodiment, an extension 26 is provided on the box body 21, and the extension 26 is fixedly installed to the mold body 1 by bolts 7. A heat insulation layer 8 is installed between the mold body 1 and the box 21; Through the technical solution of this utility model, the extension 26 provides a transition structure for the connection between the box 21 and the mold body 1. The extension 26 and the mold body 1 are fixedly installed by the bolts 7 to form a firm and detachable connection, which facilitates the disassembly of the storage box 2 for cleaning or replacement during subsequent maintenance. The heat insulation layer 8 installed between the mold body 1 and the box 21 prevents the heat generated by the friction of the wire in the mold body 1 during the wire drawing process from being transferred to the box 21, and avoids the wire drawing powder in the box 21 from clumping due to heat, thereby improving the structural stability of the self-lubricating wire drawing mold.

[0020] During use, the middle part of the conveyor 5 is provided with an arc-shaped structure with the same diameter as the metal wire; The two ends of the conveyor 5 are respectively provided with chamfers, and the chamfers are in close contact with the baffles 3 at both ends and slide in a sliding connection.

When the metal wire passes through the through hole of the storage box 2, it is precisely attached to the outer wall of the metal wire, which plays a stable guiding role for the metal wire. At the same time, when the conveying component 5 rotates, the wire drawing powder in its groove hole is attached to the surface of the metal wire. The chamfers set at both ends of the conveying component 5 are attached to the end baffles 3 and are slidably connected. The attached structure reduces the gap between the conveying component 5 and the baffles 3, preventing the wire drawing powder in the storage box 2 from leaking out of the gap and causing waste.

[0021] As a preferred embodiment of the above, the edge of the sealing element 6 is set with an angled structure, and the two sealing elements 6 are respectively installed on the two side walls of the housing 21; Through the technical solution of this utility model, the beveled structure set on the edge of the sealing element 6 guides the wire drawing powder in the storage box 2 toward the through hole in the middle of the box body 21 by using the inclined angle, ensuring that the groove hole of the conveying element 5 continuously obtains the wire drawing powder, thereby improving the utilization rate of the wire drawing powder. The two sealing elements 6 are respectively installed on the two side walls of the box body 21, forming an integrated sealing structure with the box body 21, thereby enhancing the sealing effect on both ends of the inner cavity of the storage box 2.

[0022] During use, a drain port is provided on the mold body 1; Through the technical solution of this utility model, the drain port provided on the mold body 1 discharges excess wire drawing powder, metal shavings and other impurities generated in its inner cavity during the wire drawing process, thereby preventing impurities from accumulating in the cavity and blocking the channel.
