It includes a bottom plate, and winding mechanisms are arranged on both the left and right sides of the upper end surface of the bottom plate. Between the two winding mechanisms, a plurality of drawing mechanisms for drawing the wires and a tensioning mechanism for assisting the wire drawing are detachably arranged respectively.

Description

Technical Field

[0001] The present invention belongs to the technical field of wire drawing, and particularly relates to a processing and drawing device for stainless steel wires. Background Art

[0002] The processing and drawing of stainless steel wires is a metal forming process used to process stainless steel materials into slender wire rods. This process can produce stainless steel wires with different diameters. Currently, during the drawing process of stainless steel wires, it is necessary to lubricate the stainless steel wires to reduce the friction between the wire and the die during drawing; at the same time, a mechanical force is used to pass the stainless steel blank through one or a series of die holes with gradually decreasing diameters, thereby stretching it thinner; this process involves multiple repeated operations, each time using a die with a smaller diameter until the required size is reached, and a guiding structure is usually designed between every two die holes to guide and shape the wire after the previous wire drawing is completed.

[0003] During the above-mentioned drawing and lubrication process of stainless steel wires, the lubricant is usually coated around the drawn wire. However, when the wire passes through the wire drawing guide wheel, the deformed part of the wire will not be immediately coated with the lubricant; secondly, the heat generated by the friction between the wire and the wire drawing guide wheel during continuous wire drawing will affect the quality of the wire, and at the same time, the excessive frictional resistance will affect the passing rate of the wire, resulting in a reduction in wire drawing efficiency; furthermore, because a guiding structure is set between every two die holes, the overall number of guiding structures is relatively large, which will then cause a large floor area of the entire equipment. At the same time, the resistance effects on the wire during the guiding process are superimposed, further reducing the wire drawing effect. Summary of the Invention

[0004] In view of the above problems, a processing and drawing device for stainless steel wires provided by an embodiment of the present application can achieve promoting the lubrication effect by making the wire twist during the wire drawing process of stainless steel wires, and at the same time, making small up and down swings in a small area when the wire is guided and tensioned, so as to promote the smooth passing of the wire while cooperating with multiple groups of wire guide wheels to reduce the floor area.

Detailed Description of the Invention

[0029] The following further describes the present application in detail Figures 1-10 with reference to the accompanying drawings.

[0030] Refer to Figure 1, A processing and drawing device for stainless steel wires, including a bottom plate 1. On the upper end surface of the bottom plate 1, winding mechanisms 2 are arranged on both the left and right sides. The winding mechanism 2 on the left is used to unwind the coiled stainless steel wires, and the winding mechanism 2 on the right is used to wind up the drawn stainless steel wires. Between the two winding mechanisms 2, several drawing mechanisms 3 for drawing the wires and a tensioning mechanism 4 for assisting in wire drawing are detachably arranged respectively; the drawing mechanism 3 and the tensioning mechanism 4 are intermittently arranged on the upper end surface of the bottom plate 1 in sequence.

[0031] During specific operation, first place the coiled wires to be drawn on the winding mechanism 2 on the left, then place the existing winding drum on the winding mechanism 2 on the right. According to the diameter requirements of wire drawing, several drawing mechanisms 3 and tensioning mechanisms 4 are clamped on the upper end surface of the bottom plate 1. Subsequently, one end of the wire is passed through the drawing mechanism 3 and the tensioning mechanism 4 in sequence, and finally it is fixed on the winding mechanism 2 on the right. The wire is driven to move by the winding mechanism 2 on the right to complete drawing and is wound on the winding drum.

[0032] Refer to Figure 1 、 Figure 2 and Figure 11 , On the upper end surfaces of both the left and right sides of the bottom plate 1, two strip-shaped grooves extending in the front-rear direction are opened. The winding mechanism 2 includes two L-shaped plates 11 respectively sliding inside the corresponding strip-shaped grooves. The vertical lengths of the two L-shaped plates 11 are different, and the vertical length of one L-shaped plate 11 is twice the vertical length of the other L-shaped plate 11; fixing components 12 are rotatably arranged on the horizontal sections of the two L-shaped plates 11 and the bottom plate 1.

[0033] When drawing multiple wires simultaneously, first move the corresponding two L-shaped plates 11 away from each other, then place the winding drums with wires to be drawn on the left fixing components 12 respectively. Subsequently, control the two L-shaped plates 11 to move relatively and keep the three fixing components 12 on the same vertical line. Finally, connect the three fixing components 12 into one body, and the coiled wires are externally expanded and fixed by the fixing components 12.

[0034] Refer to Figure 3 and Figure 4 , The fixing component 12 includes a stepped rotating shaft 121 installed on the bottom plate 1 and the horizontal section of the L-shaped plate 11 through bearings. The upper end of the stepped rotating shaft 121 is a frustum-shaped structure, and limiting grooves are uniformly arranged along the circumferential direction on the outer wall of its frustum-shaped structure.

[0035] Refer to Figure 3 、 Figure 5 and Figure 6, on the circumferential outer wall of the upper half of the stepped rotating shaft 121, clamping grooves are uniformly arranged below the limiting grooves. Inside the clamping grooves, locking blocks 122 are slidably arranged through springs in cooperation with limiting rods. The limiting rods are installed in the clamping grooves and are slidably connected to the locking blocks 122. The springs are sleeved outside the limiting rods, with one end connected to the inner side wall of the clamping grooves and the other end connected to the side end of the locking blocks 122. The locking blocks 122 slide along the radial direction of the stepped rotating shaft 121; a supporting plate 123 is arranged on the circumferential outer wall of the stepped rotating shaft 121 below the locking blocks 122; the inside of the stepped rotating shaft 121 is set as a cavity structure. Inside the cavity of the stepped rotating shaft 121, an operating rod 124 is arranged through a bearing. A torsion spring with one end fixed on the operating rod 124 and the other end fixed on the inner wall of the cavity of the stepped rotating shaft 121 is sleeved on the outer wall of the operating rod 124; the upper end of the operating rod 124 is fixedly connected with a cam disc 125. The cam disc 125 cooperates with the inner walls of a plurality of locking blocks 122. A clamping plate 126 located below the supporting plate 123 is fixedly sleeved on the lower side outer wall of the operating rod 124. 7-shaped grooves 127 are symmetrically arranged on the lower end outer wall of the stepped rotating shaft 121.

[0036] Refer to Figure 4 , a first clamping sleeve 1271 with a tapered inner cavity is slidably arranged on the lower side outer wall of the stepped rotating shaft 121 on the L-shaped plate 11. U-shaped plates 1272 that are engaged with the clamping plate 126 are symmetrically arranged on the inner wall of the first clamping sleeve 1271. The U-shaped plates 1272 are located in the 7-shaped grooves 127; a protruding structure that cooperates with the limiting grooves is arranged on the inner wall of the first clamping sleeve 1271.

[0037] Refer to Figure 3 , a second clamping sleeve 1281 is slidably arranged on the lower side outer wall of the stepped rotating shaft 121 on the bottom plate 1. U-shaped plates 1272 that are engaged with the clamping plate 126 are also symmetrically arranged on the inner wall of the second clamping sleeve 1281. The U-shaped plates 1272 are located in the 7-shaped grooves 127; a bevel gear 1282 is fixedly arranged at the lower end of the stepped rotating shaft 121 on the bottom plate 1.

[0038] The take-up reel around which the wire to be drawn is wound is sleeved on the outer wall of the stepped rotating shaft 121 and supported by the supporting plate 123. Move the three fixing components 12 to be on the same vertical line. Then, drive the U-shaped plate 1272 and the clamping plate 126 to rotate by rotating the first clamping sleeve 1271. Drive the cam disc 125 to rotate by the clamping plate 126. The U-shaped plate 1272 rotates along the horizontal section of the 7-shaped groove 127. The rotation of the cam disc 125 cooperates with the surrounding locking blocks 122, pushing the locking blocks 122 out to the outside of the stepped rotating shaft 121. The locking blocks 122 move along the clamping grooves and the limiting rods and compress the corresponding springs. The take-up reel is internally supported and fixed by the outward expansion of the locking blocks 122. Then, the first clamping sleeve 1271 drives the corresponding U-shaped plate 1272 to slide downward along the vertical section of the 7-shaped groove 127, so that the first clamping sleeve 1271 is sleeved on the top of the lower stepped rotating shaft 121. The first clamping sleeve 1271 is clamped and matched with the clamping groove at the upper end of the lower stepped rotating shaft 121. Thus, the stepped rotating shafts 121 on the same vertical line are locked as a whole. Similarly, operate the second clamping sleeve 1281 to control the outward expansion of the corresponding locking blocks 122 to internally support and fix the take-up reel. After completion, the second clamping sleeve 1281 drives the corresponding U-shaped plate 1272 to move downward to the vertical section of the 7-shaped groove 127. The vertical section of the 7-shaped groove 127 can limit the rotation of the U-shaped plate 1272, and then limit the rotation of the cam disc 125 to maintain the internally supported and fixed state of the locking blocks 122. During subsequent unwinding and winding, cooperate with the bevel gear 1282 through external driving respectively, so as to control the stepped rotating shaft 121 to drive to complete the winding and unwinding of the drawn wire. The provided fixing components 12 can perform wire drawing operations on multiple wires simultaneously. The multiple wires are arranged in sequence in the vertical direction, which can reduce the floor area, and the fixing components 12 on the same vertical line can be linked as a whole to ensure the synchronization of wire drawing of multiple wires.

[0039] Refer to Figure 7 , Figure 8 and Figure 9 , the wire drawing mechanism 3 includes a fixing block 31 clamped on the bottom plate 1. The fixing block 31 is evenly provided with left-right through mounting through holes from top to bottom. Wire drawing guide wheels 32 are uniformly arranged in the mounting through holes from top to bottom through bearings. The inlet end of the wire drawing guide wheel 32 is an flared structure, and a gear ring 33 is arranged at a position on the circumferential outer wall of the wire drawing guide wheel 32 close to the inlet end. An arc-shaped groove is arranged at a position on the circumferential outer wall of the wire drawing guide wheel 32 close to the outlet end, and oil guide holes 34 communicated with the internal wire guiding holes of the wire drawing guide wheel 32 are uniformly arranged in the arc-shaped groove; a fuel storage tank 35 is arranged at the upper end of the fixing block 31. An oil outlet hole 36 is arranged inside the fuel storage tank 35. The oil outlet hole 36 is communicated with the adjacent arc-shaped groove. An oil delivery channel communicating the arc-shaped grooves on two adjacent wire drawing guide wheels 32 is arranged inside the fixing block 31.

[0040] Refer to Figure 7, an installation groove is provided on the side wall of the fixed block 31. A rack 37 that meshes with each gear ring 33 simultaneously is slidably arranged in the installation groove. One end of the rack 37 is connected with a telescopic push rod 38, and the telescopic push rod 38 is arranged on the side wall of the installation groove.

[0041] During drawing, the steel wire is sequentially passed through the wire drawing guide wheels 32. During the subsequent winding movement of the steel wire, drawing and diameter reduction are completed. During the winding movement of the steel wire, the lubricating oil stored inside the oil storage tank 35 will enter the interior of each oil guide hole 34 along the oil outlet hole 36, and circumferential lubrication will be performed when the steel wire is drawn through the wire drawing guide wheel 32. On the one hand, it reduces the temperature on the surface of the steel wire, and on the other hand, it improves the passing rate of the steel wire during the drawing process; at the same time, the telescopic push rod 38 will reciprocally push the rack 37 to move, thereby indirectly controlling each wire drawing guide wheel 32 to perform a small-angle circumferential rotation. The rotation of the wire drawing guide wheel 32 drives the steel wire to twist, thereby on the one hand promoting the uniform application of the lubricating fluid on the surface of the steel wire, and on the other hand, it can reduce the resistance during the drawing of the steel wire and improve the passing rate of the steel wire.

[0042] Refer to Figure 1 and Figure 2 , the tensioning mechanism 4 includes a vertical plate 41 detachably installed on the bottom plate 1. Two vertical sliding grooves are opened on the vertical plate 41. Four groups of wire guide wheels are arranged on the vertical plate 41. The number of wire guide wheels in each group of wire guide wheels is three. The two groups of wire guide wheels in the middle are respectively slidably arranged in the corresponding sliding grooves, and the other two groups of wire guide wheels are fixedly arranged on the vertical plate 41.

[0043] Refer to Figure 1 , Figure 2 and Figure 11 , a rectangular frame 42 is slidably connected to the outside of the sliding groove. Pin holes are uniformly arranged on the side wall of the rectangular frame 42. The three wire guide wheels in the sliding groove are all fixed on the rectangular frame 42 through the cooperation of pins and the corresponding pin holes. Tooth-like structures are arranged on one side wall of the two rectangular frames 42 close to each other. A driving motor 43 is arranged on the outer side wall of the vertical plate 41 through a motor base. A driving gear 44 that meshes with the tooth-like structures on both sides simultaneously is arranged on the output shaft of the driving motor 43.

[0044] When the drawn steel wire is tensioned by the tensioning mechanism 4, the height difference between the two groups of wire guide wheels in the middle is adjusted according to actual requirements. When specifically adjusting the height, the pin is removed, and then the two groups of wire guide wheels in the middle are slid to adjust the height difference between the two relatively positioned wire guide wheels in the two groups of wire guide wheels. After adjustment, the wire guide wheels are fixed to the rectangular frame 42 by inserting the pin into the corresponding pin hole; then the steel wire is sequentially passed through the four groups of wire guide wheels, and finally the driving motor 43 drives the driving gear 44 to rotate to control the two groups of wire guide wheels in the middle to alternately move up and down. During the process of the two groups of wire guide wheels alternately moving up and down, the steel wire can be tractioned and dragged, improving the drawing effect and plastic effect of the steel wire.

[0045] Refer to Figure 10 , a two-way lead screw 51 is arranged below the lower end surface of the bottom plate 1 and directly below the winding mechanism 2 through bearings. The threaded sections of the two-way lead screw 51 are respectively threadedly connected to the lower ends of the corresponding two L-shaped plates 11; one end of the two-way lead screw 51 is connected with a crank 52; operating the crank 52 can control the rotation of the two-way lead screw 51, and then make the two L-shaped plates 11 on the two-way lead screw 51 move synchronously in opposite directions to complete the placement and removal of the winding drum.

[0046] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
