Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing dies, in particular to a die orifice assembly of a wire drawing die. Background Technique

[0002] A wire drawing die is a tool used for metal processing, usually used to draw metal materials (such as aluminum, steel, copper, etc.) into long and thin shapes, such as wire, rope, cable, etc. This process is usually called wire drawing, which stretches the metal blank through one or more die holes to reduce its cross-sectional area, so as to obtain the required size and shape. The die orifice assembly of a wire drawing die usually refers to the outlet part of the die, which is used to determine the cross-sectional shape and size of the product after wire drawing. This assembly includes the outlet part of the die and related accessories.

[0003] The die orifice assembly of a traditional wire drawing die consists of parts such as a die orifice plate, a wire drawing hole, a sleeve, and a die hole. By guiding the metal blank into the die hole, once the metal blank enters the die hole opening, the wire drawing hole on the die orifice plate of the wire drawing die will gradually decrease, resulting in a decrease in the cross-sectional area of the metal blank. The metal blank is restricted by the die hole opening and begins to undergo tensile deformation, with the length gradually increasing and the cross-sectional area gradually decreasing, and finally a wire drawing product with the required size and shape is formed.

[0004] The die orifice assemblies of traditional wire drawing dies are all integrated, which is not convenient for disassembling and replacing damaged die cores. After the die cores are damaged, the entire wire drawing die needs to be directly replaced, increasing the use cost of the wire drawing die.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1 - 4 , an embodiment provided by the present invention: a die orifice assembly of a wire drawing die, including a mold shell 1, a mold core 2 is slidably connected inside the mold shell 1, a sliding bar 3 is slidably connected inside the mold shell 1, a limit assembly is arranged on the side wall of the sliding bar 3, a first fixing column 5 is fixedly connected inside the mold shell 1, a clamping block 6 is rotatably connected to the side wall of the first fixing column 5, a first spring 7 is arranged inside the mold shell 1, one end of the first spring 7 is fixedly connected to the inner wall of the mold shell 1, the other end of the first spring 7 is fixedly connected to a first fixing block 8, the side wall of the first fixing block 8 is slidably connected inside the mold shell 1, the side wall of the clamping block 6 is in contact with the side wall of the first fixing block 8, a second fixing block 9 is fixedly connected to the inner wall of the mold shell 1, a second spring 10 is arranged on the side wall of the second fixing block 9, one end of the second spring 10 is fixedly connected to a third fixing block 11, the other end of the second spring 10 is fixedly connected to the side wall of the second fixing block 9, the side wall of the third fixing block 11 is in contact with the side wall of the mold core 2, a slide groove 14 is opened inside the mold shell 1, a card slot 13 is opened on the side wall of the mold core 2, the side wall of the clamping block 6 is slidably connected inside the card slot 13, a fixing strip 12 is fixedly connected to the side wall of the mold core 2, and the side wall of the fixing strip 12 is slidably connected inside the slide groove 14. The limit assembly includes a limit block 4, the side wall of the limit block 4 is fixedly connected to the side wall of the sliding bar 3, and the side wall of the limit block 4 is slidably connected inside the mold shell 1;

[0035] When the mold core 2 needs to be replaced, first press the sliding bar 3 to make it press down inside the mold shell 1. When the sliding bar 3 touches the clamping block 6, the first fixing block 8 that fits with the clamping block 6 will slide inside the mold shell 1, causing the first spring 7 to be compressed and contract. As the first spring 7 contracts, the clamping block 6 will be subjected to the pressure from the sliding bar 3 and then rotate on the side wall of the first fixing column 5. At this time, the second spring 10 that was originally pressed by the clamping block 6 will lose pressure and start to rebound. Under the rebounding action of the second spring 10, the third fixing block 11 will eject the mold core 2 from inside the mold shell 1. At this time, release the pressed sliding bar 3 to allow the first spring 7 to rebound, and through the action of the first fixing block 8, the sliding bar 3 will reset to its original position. Then the mold core 2 can be taken out from the mold shell 1 to prepare for installing a new mold core 2. When a new mold core 2 needs to be installed, first align the fixing bar 12 with the chute 14 inside the mold shell 1 to ensure that the corresponding positions of the fixing bar 12 and the chute 14 are accurate. Then slide the new mold core 2 into the mold shell 1 along the direction of the chute 14. During the sliding process, the downward pressure of the mold core 2 will cause the third fixing block 11 to be pressed, thereby causing the second spring 10 to contract. As the mold core 2 continues to slide, the side wall of the clamping block 6 will move along the side wall of the mold core 2. During this process, the first spring 7 will also be compressed. When the clamping block 6 moves to the card slot 13 on the side wall of the mold core 2, due to the elastic action of the first spring 7, the clamping block 6 will snap into the inside of the card slot 13. At this time, the first spring 7 loses pressure and remains in a stable state to ensure that the clamping block 6 can be firmly fixed in the card slot 13. At this time, the new mold core 2 is installed inside the mold shell 1.

[0036] Refer to Figures 5 - 6 , a cooling pipe 15 is provided inside the mold shell 1. Both ends of the cooling pipe 15 penetrate through the mold shell 1 and extend to the outside. A cooler 18 is provided on the side wall of the mold shell 1. The output end of the cooler 18 is fixedly connected to a water inlet pipe 16, and the input end of the cooler 18 is fixedly connected to a connecting pipe 19. One end of the water inlet pipe 16 is fixedly connected to one end of the cooling pipe 15. A fixing sleeve 17 is fixedly connected to the side wall of the water inlet pipe 16. A water tank 21 is fixedly connected to the side wall of the mold shell 1. A piston 22 is provided inside the water tank 21. A water tank 21 is provided on the side wall of the mold shell 1. A water pump 20 is fixedly connected to the side wall of the water tank 21. The output end of the water pump 20 is fixedly connected to one end of the connecting pipe 19. The lower surface of the water tank 21 is fixedly connected to a water outlet pipe 23. One end of the water outlet pipe 23 is fixedly connected to the other end of the cooling pipe 15.

[0037] When using this device for wire drawing of metal blanks, first, the workpiece to be processed needs to be placed into the interior of the die core 2 through the opening of the die core 2. In this step, the workpiece is accurately positioned and fixed. During the wire drawing process, since the workpiece will be affected by high temperature and high pressure during wire drawing, in order to reduce damage to the wire drawing die, first, the piston 22 is pulled out from the water tank 21, then the water tank 21 is filled with water. After filling with water, the piston 22 is inserted into the water tank 21 to ensure the sealing of the water tank 21. Subsequently, by starting the water pump 20, the water in the water tank 21 is pumped in and enters the interior of the cooler 18 through the connecting pipe 19. The cooler 18 is an existing device and will not be elaborated here. The cooled water then enters the interior of the cooling pipe 15 through the water inlet pipe 16, bringing the cooled water into the die shell 1, effectively reducing the internal temperature. This cooling measure reduces the damage of high temperature to the wire drawing die, extends the service life of the die. At the same time, the water brought into the interior of the die shell 1 will flow through the die shell 1 and then flow back into the water tank 21 again through the water outlet pipe 23, forming a complete circulation process. Under the restraint of the interior of the die core 2 and the cooling effect of the cooling water, the metal blank begins to gradually stretch and deform. After a series of processing steps, a wire drawing product is finally formed.

[0038] Working principle: When using this device for wire drawing of metal blanks, first place the workpiece to be processed into the inside of the die core 2 through the opening of the die core 2. Since the workpiece will be affected by high temperature and high pressure during the wire drawing process, in order to reduce the damage to the wire drawing die, at this time, first pull out the piston 22, then add water to the inside of the water tank 21. After adding water, then insert the piston 22 into the water tank 21. Then, by starting the water pump 20, the water in the water tank 21 enters the inside of the cooler 18 through the connecting pipe 19. The cooled water then enters the inside of the cooling pipe 15 through the water inlet pipe 16, and further brings the cooled water into the die shell 1 to cool its inside, thereby reducing the damage of high temperature to the wire drawing die. The water brought into the die shell 1 will also flow back into the water tank 21 through the water outlet pipe 23 after flowing through the die shell 1, thus achieving a circulating effect. Due to the constraint of the die core 2 on the metal blank, it starts to stretch and deform, and finally forms a wire-drawn product. When the die core 2 needs to be replaced, first press the sliding bar 3 to make it press down inside the die shell 1. When it touches the latch 6, the fixing block one 8 that fits with the latch 6 slides inside the die shell 1 to compress and contract the first spring 7. Due to the pressure on the latch 6, the latch 6 rotates on the side wall of the fixing column one 5, and then slides the side wall of the latch 6 out of the slot 13 on the side wall of the die core 2. At this time, the second spring 10 rebounds without pressure, and the fixing block three 11 ejects the die core 2 from the inside of the die shell 1. At this time, release the pressed sliding bar 3 to make the first spring 7 rebound, and then make the sliding bar 3 reset through the fixing block one 8. Then the die core 2 can be taken out. When a new die core 2 needs to be installed, first align the fixing bar 12 with the sliding groove 14, and then slide the die core 2 into the inside of the die shell 1. During the sliding process, due to the downward pressure of the die core 2, the fixing block three 11 slides, compressing the second spring 10, and making the side wall of the latch 6 stick to the side wall of the die core 2, compressing the first spring 7. Until the latch 6 touches the slot 13, the first spring 7 loses pressure, and the latch 6 snaps into the inside of the slot 13 to complete the fixation.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
