Description

Technical Field

[0001] The invention relates to the technical field of wire drawing devices, in particular to a high-stability wire drawing die with self-addition of lubricating oil. Background Art

[0002] A wire drawing die is a tool used during metal pressure processing to force metal through the die under the action of external force, compress the metal cross-sectional area, and obtain the required cross-sectional shape and size. Commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are all drawn using diamond wire drawing dies.

[0003] Diamond wire drawing dies are made of natural diamond as raw material, so they have strong wear resistance and extremely long service life. The production process of wire drawing die inserts includes several process steps such as die pressing, die drawing, and turning. The wire drawing die passes the metal wire through the die, making it from coarse to fine, and gradually reaches the size people need. This special die is the wire drawing die. The core of the wire drawing die is generally made of natural diamond or artificial diamond (artificial diamond includes GE, PCD, synthetic materials, etc.). The workpieces that need to be drawn include tungsten, copper, etc. The cross-sectional shape of the workpiece after drawing is determined by the shape of the core.

[0004] When some metal materials are being drawn, it is necessary to apply lubricating oil to the surface of the metal materials to reduce the wear of the metal materials and the drawing dies during the drawing process. At the same time, the lubricating oil makes the drawing process smoother. The lubricating oil is provided and tested by the oil tank to ensure the amount of oil retained on the surface of the wire. Lubricating oils of different viscosities have different fluidity. Lubricating oils with strong fluidity are used in the drawing process. Common ways to add lubricating oil include spray lubrication and manual application.

[0005] Spray lubrication has a wide spraying surface. When drawing a workpiece with a small radius, most of the lubricant will not flow onto the outer surface of the workpiece. The amount of lubricant transported at the same time is large, but very little lubricant is used for lubrication. Manual application requires a brush or sponge to be held by hand throughout the application process, and long-term operation will increase the burden on the operator. Regardless of the method used, the lubricant will fall directly on the upper surface of the workpiece, and then rely on the power of the lubricant itself to drive the lubricant to flow to the lower surface of the workpiece, which will cause uneven application of the lubricant on the lower surface of the workpiece. This causes defects on the outer surface of the workpiece after drawing. Summary of the invention

[0041] The inner ring frame 8 includes an inner ring surface 11, and the inner ring surface 11 is connected to a lubricating part 20 through a replacement component, and the lubricating part 20 can be replaced regularly; the lubricating part 20 rotates 360 degrees around the outer wall of the workpiece, so that the outer wall of the workpiece is coated with lubricating oil 360 degrees. Because the workpiece is constantly moving forward during the wire drawing process, the outer wall of the entire workpiece is coated with lubricating oil, which can reduce the amount of lubricating oil supplied each time the lubricating oil is added, and the outer wall of the workpiece can be quickly and evenly coated with lubricating oil 360 degrees.

[0043] And a transmission member, the transmission member is located on the outer wall of the inner ring frame 8, and the outer wall of the transmission member is provided with an extrusion mechanism.

[0044] The lubricating component 20 includes an insert block 21, a support tube 22 and an oiling component 23. The side wall of the support tube 22 is symmetrically provided with an insert block 21. The inner wall of the support tube 22 is provided with an oiling hole 3. The inner wall of the oiling hole 3 is fixedly provided with an oiling component 23. The insert block 21 is plugged into the slot 13. A lubricating component 20 and a lubricating mechanism that fit together form a group. The oiling component 23 will be worn after long-term use. The support tube 22 can be pulled outward, and the support tube 22 can drive the insert block 21 to disengage from the slot 13, so that the lubricating component 20 can be removed for replacement, and a new lubricating component 20 can be taken out and inserted back into its original position. Because the C end is located at one end of the inner ring frame 8 close to the oiling hole 1 9, the opening 14 is located at one end of the inner ring frame 8 close to the oiling hole 2 10, and the direction of the workpiece moving forward is as follows. Figure 1 As shown, the advancing workpiece will drive the plug block 21 to approach the c end, and the connection between the plug block 21 and the slot 13 can be strengthened without adding bolts, so as to prevent the lubricating part 20 from falling off and ensure the stability of the equipment operation. The lubricating part 20 can lubricate workpieces of different radii.

[0045] The support tube 22 is made of deformable material, the central axis of the oil hole 10 is along the radius direction of the inner ring frame 8, and the oiling member 23 is a sponge or a brush. When the workpiece is about to be inserted into the inner ring frame 8, if the radius of the workpiece is equal to the radius of the processing circle t, the workpiece can be directly passed through the inner ring frame 8, and at this time, the end of the oiling member 23 is in contact with the outer wall of the workpiece;

[0046] If the radius of the workpiece is larger than the radius of the processing circle t and smaller than the radius of the processing circle s, the support tube 22 is moved by tools or by hand. Because the support tube 22 is made of deformable material, the sponge or brush can also be deformed, so when the support tube 22 is tilted, the oiling part 23 will also be tilted. Figure 3 As shown in the direction of the arrow, the angle of the movement is determined according to the radius of the workpiece, so that the side of the oil-coated member 23 fits the workpiece. The oil delivery pipe 15 is connected to an external oil delivery device, and the oil delivery device supplies lubricating oil to the oil delivery pipe 15 according to the setting of the controller. The lubricating oil passes through the oil delivery pipe 15, the oil hole 1 9, and the oil hole 2 10 and then enters the oil hole 3, so that the oil-coated member 23 in the oil hole 3 is covered with lubricating oil. After the oil-coated member 23 fits the workpiece, the lubricating oil is applied to the outer wall of the workpiece.

[0047] The inner wall of the bracket 6 is provided with a motor 24, the output shaft of the motor 24 is connected to the transmission member, and the bottom of the mold frame 1 is provided with a filter 25. The debris and will fall on the filter 25, and the debris will be collected centrally. If the lubricating oil drips due to improper operation, it will also drip into the mold frame 1 for centralized collection.

[0048] The transmission member includes a transmission shaft 31, a circular gear 1 32 and a circular gear 2 33. The transmission shafts 31 are symmetrically arranged on both sides of the inner ring frame 8. A circular gear 1 32 is arranged on the outer wall fixing sleeve of one of the transmission shafts 31. A circular gear 2 33 is arranged on the output shaft fixing sleeve of the motor 24. The circular gear 1 32 is meshed with the circular gear 2 33.

[0049] The transmission shaft 31 includes an inner ring surface 2, the inner ring surface 11 has the same radius as the inner ring surface 2, and the transmission shaft 31 is concentric with the inner ring frame 8;

[0050] The extrusion structure includes an upper plate 41, a spring 42, a lower plate 43, an adjustment frame 44, a side plate 45, a lifting shaft 46, an electric push rod 50 and an extrusion roller 47. The upper plate 41 is fixedly provided on the outer wall of the transmission shaft 31. The bottom end of the upper plate 41 is connected to the lower plate 43 through a spring 42. The bottom end of the lower plate 43 is provided with an adjustment frame 44. The side wall of the outer ring frame 7 is provided with an electric push rod 50. The inner wall of the upper plate 41 is provided with a through hole 51. The radius of the telescopic end of the electric push rod 50 is smaller than the radius of the through hole 51, and the radius of the through hole 51 is smaller than the outer diameter of the spring 42.

[0051] The inner wall of the inner ring surface 11 is symmetrically provided with side plates 45 on both sides of the lubricating member 20, and the inner wall of the side plate 45 is symmetrically provided with sliding grooves 48;

[0052] In the same group, the side plates 45 on both sides are connected by a lifting shaft 46, the end of the lifting shaft 46 is slidably connected to the slide 48 through a slider 49, and the outer wall of the lifting shaft 46 is rotatably sleeved with an extrusion roller 47. After the daily wire drawing work is completed, the brush or sponge will still be full of lubricating oil. If it is not handled in time after the equipment is idle, the lubricating oil on the brush or sponge will deteriorate, adhere to more dust or be lost in vain. If there is still a small part of the wire drawing work of this device to be completed, the specific remaining workload is calculated according to the actual operation, which is described in detail here, and the oil pipeline 15 stops delivering oil. Afterwards, when no workpiece passes through the inner ring frame 8, the extrusion structure is started to squeeze the support cylinder 22, and the pressure is transmitted to the part of the oil-coated member 23 located inside the support cylinder 22. After being squeezed, the lubricating oil in the support cylinder 22 is squeezed to the coating end of the oil-coated member 23, thereby increasing the amount of lubricating oil adhered to the coating end of the oil-coated member 23. The lubricating oil on the oil-coated member 23 can be squeezed so that the lubricating oil is gathered at the coating end of the oil-coated member 23. The lubricating oil adhered to the oil-coated member 23 can be reasonably utilized to avoid a large amount of lubricating oil remaining on the oil-coated member 23 and causing a waste of resources.

[0053] The slide groove 48 includes an inclined portion and a vertical portion connected in sequence from top to bottom, and the position of the slider 49 is limited by the adjustment frame 44 .

[0054] The inner wall of the adjustment frame 44 is provided with an adjustment groove, and the adjustment groove includes an inclined e-surface and an inclined f-surface, the e-surface is located at the top of the adjustment groove, and the f-surface is located at the bottom of the adjustment groove, the top of the slider 49 is provided with a g point, and the bottom of the slider 49 is provided with an h point, the g point is in contact with the e-surface, and the h point is in contact with the f-surface, the angle between the e-surface and the ground is -45 degrees, and the angle between the f-surface and the ground is 45 degrees.

[0055] The specific implementation method is as follows: when in use, the length of the mold frame 1 is set according to the production needs, and the number of mold seats 2 set on the top of the mold frame 1 is set, and the mold core 3 of the required specifications is inserted into the drawing hole 1 4. The mold seat 2 is pressed against the positioning surface by the positioning bolts, so as to fix the mold core 3. This part is the existing technology. The two ends of the workpiece to be drawn are the m end and the n end respectively. The m end of the workpiece to be drawn is passed through the drawing hole 2 5, the inner ring frame 8, the b end, the a end and the drawing hole 1 4. The external power device for drawing clamps the m end and pulls the workpiece outward, driving the workpiece to move forward in the mold seat 2 until the n end of the workpiece passes through the mold seat 2. Lubricating oil is always added to the workpiece for lubrication during the process of the workpiece moving forward;

[0056] The lubricating element 20 can lubricate workpieces of different radii. Figure 4 In the figure, the area between the processing circle s and the processing circle t is the processable range of the lubricating element 20, wherein the processing circle s is the maximum radius of the workpiece that can be drawn, and the processing circle t is the minimum radius of the workpiece that can be drawn.

[0057] The specific lubrication process is as follows:

[0058] Step 1: When the end m of the workpiece passes through the drawing hole 2 5 in sequence and reaches the inner ring frame 8, when the workpiece is about to be inserted into the inner ring frame 8, if the radius of the workpiece is equal to the radius of the processing circle t, the workpiece can be directly passed through the inner ring frame 8. At this time, the end of the oil-coated part 23 is in contact with the outer wall of the workpiece;

[0059] If the radius of the workpiece is larger than the radius of the processing circle t and smaller than the radius of the processing circle s, the support tube 22 is moved by tools or by hand. Because the support tube 22 is made of deformable material, the sponge or brush can also be deformed, so when the support tube 22 is tilted, the oiling part 23 will also be tilted. Figure 3 As shown in the direction of the arrow, the angle of the movement is determined according to the radius of the workpiece, so that the side surface of the oil-coated member 23 fits the workpiece.

[0060] Step 2: The oil delivery pipe 15 is connected to an external oil delivery device. The oil delivery device supplies lubricating oil to the oil delivery pipe 15 according to the setting of the controller. The lubricating oil passes through the oil delivery pipe 15, the oil hole 1 9, and the oil hole 2 10 and then enters the oil hole 3, so that the oil-coated part 23 in the oil hole 3 is covered with lubricating oil. After the oil-coated part 23 is fitted with the workpiece, the lubricating oil is applied to the outer wall of the workpiece.

[0061] Step 3, the output shaft of the motor 24 drives the circular gear 2 33 to rotate, the circular gear 1 32 meshes with the circular gear 2 33, the circular gear 1 32 drives the transmission shaft 31 and the inner ring frame 8 on its inner wall to rotate synchronously, the inner ring frame 8 drives the replacement component, the extrusion structure and the lubricating part 20 to rotate synchronously, and when the oil hole 3 is aligned with the oil hole 2 10, the lubricating oil will be transported into the oil hole 3, realizing the self-adding lubricating oil operation;

[0062] The lubricating part 20 rotates 360 degrees around the outer wall of the workpiece, so that the outer wall of the workpiece is coated with lubricating oil at 360 degrees. Because the workpiece is constantly moving forward during the wire drawing process, the outer wall of the entire workpiece is coated with lubricating oil, which can reduce the amount of lubricating oil supplied each time the lubricating oil is added, and the outer wall of the workpiece can be quickly and evenly coated with lubricating oil at 360 degrees.

[0063] After the daily wire drawing work is completed, the brush or sponge will still be full of lubricating oil. If it is not handled in time after the equipment is idle, the lubricating oil on the brush or sponge will deteriorate, adhere to more dust or be lost in vain. If there is still a small part of the wire drawing work of the present device to be completed, the specific remaining workload is calculated according to the actual operation, which is described in detail here, and the oil delivery pipe 15 stops delivering oil. After that, when there is no workpiece passing through the inner ring frame 8, the extrusion structure is started to extrude the support cylinder 22, and the pressure is transmitted to the part of the oiling member 23 located inside the support cylinder 22. After being squeezed, the lubricating oil in the support cylinder 22 is squeezed to the coating end of the oiling member 23, increasing the amount of lubricating oil adhered to the coating end of the oiling member 23, and the lubricating oil on the oiling member 23 can be squeezed so that the lubricating oil is gathered at the coating end of the oiling member 23. The lubricating oil adhered to the oiling member 23 can be reasonably used to avoid a large amount of lubricating oil remaining on the oiling member 23 and causing waste of resources.

[0064] The extrusion process of the specific extrusion structure is as follows:

[0065] S1. When the through hole 51 rotates to the position directly below the electric push rod 50, the motor 24 stops rotating, the telescopic end of the electric push rod 50 extends, passes through the through hole 51 and the spring 42 and contacts the lower plate 43, the electric push rod 50 continues to extend and pushes the lower plate 43 downward, the spring 42 is stretched, the lower plate 43 drives the adjustment frame 44 to move downward synchronously, the e surface of the adjustment frame 44 fits with the g point, and the slider 49 can be pushed downward, the slider 49 drives the lifting shaft 46 and the squeezing roller 47 to move downward synchronously, because the slide groove 48, the g point and the e surface are restricted by the slider 49, the squeezing roller 47 will move downward along the inclined part and the vertical part, and the two squeezing rollers 47 on the outer side of the support tube 22 gradually approach to squeeze the support tube 22;

[0066] S2. After the extrusion is completed, the electric push rod 50 contracts, and the telescopic end of the electric push rod 50 is separated from the lower plate 43. Under the action of the elastic force of the spring 42 itself, the spring 42 contracts and drives the lower plate 43 to move upward and reset. Because the slide groove 48, point h and point f face the restrictions of the slider 49, the extrusion roller 47 will move upward and reset along the vertical part and the inclined part until the next through hole 51 rotates to the bottom of the electric push rod 50.

[0067] After long-term use, the oiling part 23 will be worn. The support tube 22 can be pulled outward, and the support tube 22 drives the insert block 21 to disengage from the slot 13, so that the lubricating part 20 can be removed for replacement, and the new lubricating part 20 can be inserted back into the original position.
