Description

Technical Field

[0001] This invention belongs to the technical field of metal wire mesh production equipment, specifically relating to a slitting and warping device. Background Technology

[0002] High-strength metal wires mainly include high-carbon steel wire, stainless steel wire, tungsten wire, etc. In the process of preparing tungsten alloy fine wires, it is necessary to warp the tungsten alloy fine wires through warping equipment. The warping machine uses tensioners, yarn guides and adjusting wheels to sort and adjust the tungsten alloy fine wires in order to improve the uniformity and stability of the tungsten alloy fine wires.

[0003] In existing warping equipment, one end of a tungsten alloy filament is fixed to a warping shaft during warping. The filament is wound onto the shaft by its rotation. After a predetermined length is wound, the shaft stops rotating, is removed from the warping machine, and replaced with a new one. Specifically, before starting warping, the operator divides several tungsten alloy filaments into three or four groups, and then ties each group of filaments to a corresponding connecting rope on the warping shaft. After rotating the warping shaft, the filaments gradually cover the shaft. As the shaft continues to rotate, the filaments are wound to a predetermined thickness.

[0004] Although binding the tungsten alloy filaments together with connecting ropes can fix the ends of the filaments, the binding increases the winding diameter during winding, which can affect the tungsten alloy filaments initially wound onto the warp beam. Summary of the Invention

[0005] This invention provides a slitting and warping device, which aims to reduce the impact of the connection position between the tungsten alloy filament and the warping shaft on the tungsten alloy filament.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A slitting and warping device is provided, comprising a device body and a warping shaft rotatably mounted on the device body, wherein both ends of the warping shaft are connected to baffles; the outer peripheral wall of the warping shaft is provided with a plurality of strip-shaped holes spaced along its axial direction, each strip-shaped hole being used for insertion and mating with the end of a tungsten alloy filament.

[0008] The warping shaft is also provided with a clamping member for inserting and engaging with the strip hole. After the clamping member is inserted and engaged with the strip hole, the outer peripheral wall of the clamping member is coplanar with the outer peripheral wall of the warping shaft. One side of the clamping member engages with the side wall of the strip hole to press against the tungsten alloy wire inside the strip hole.

[0009] In one possible implementation, the sidewall of the abutment has an elastic layer for abutting the tungsten alloy filament inside the slot;

[0010] The opening of the strip-shaped hole has an arc-shaped transition surface, so that when the end of the tungsten alloy wire is fixed in the strip-shaped hole, the tungsten alloy wire can contact the arc-shaped transition surface.

[0011] In one possible implementation, the outer peripheral wall of the abutment is connected to an elastic cloth, the two ends of the elastic cloth are fixed to the abutment, and the middle part of the elastic cloth is attached to the outer peripheral wall of the abutment.

[0012] The elastic fabric can be stretched outward in the middle to create a lifting space between the elastic fabric and the abutment.

[0013] In one possible implementation, the inner end of the abutment is provided with an opening, and the opening of the abutment can be inserted and engaged with a tungsten alloy wire.

[0014] In this process, after the tungsten alloy filament is inserted into the opening of the abutment, the abutment is inserted into the strip hole to abut the tungsten alloy filament.

[0015] In one possible implementation, the bottom wall of the strip-shaped hole has an arcuate groove for avoiding tungsten alloy filaments.

[0016] In one possible implementation, the opening of the abutment is provided with a clamping plate, and the side wall of the abutment has a threaded hole with a set screw threaded into the threaded hole.

[0017] When the tungsten alloy filament is inserted into the opening of the clamping member, the clamping plate presses against the tungsten alloy filament under the pushing action of the top screw.

[0018] In one possible implementation, the side wall of the abutment has a receiving hole, a limiting rod is slidably disposed in the receiving hole, and the inner wall of the strip hole has an insertion hole, the limiting rod being inserted into the insertion hole.

[0019] The limiting rod is fitted with an elastic element, the two ends of which are connected to the limiting rod and the abutment respectively; the abutment has a reset structure, which is used to provide tension to the limiting rod so that the limiting rod separates from the insertion hole.

[0020] In one possible implementation, the reset structure includes a pull rope, one end of which is connected to the inner end of the limiting rod, and the other end of which extends through the outer peripheral wall of the abutment.

[0021] The outer peripheral wall of the clamping member has a clearance hole for the pull rope to pass through, and the end of the pull rope has a knot head, which is located inside the clearance hole.

[0022] In one possible implementation, the clearance hole is a stepped hole, and the knotting head is located at the opening with a larger diameter.

[0023] In one possible implementation, the clamping member is a conical structure, and the strip hole is a conical groove.

[0024] This invention provides a slitting and warping device. Compared with the prior art, by setting strip-shaped holes on the warping shaft, a number of tungsten alloy wires are divided into groups corresponding to the number of strip-shaped holes. Each group of tungsten alloy wires is inserted into the corresponding strip-shaped hole, and a clamping member is inserted and engaged with the strip-shaped hole, which can clamp the end of the tungsten alloy wire in the strip-shaped hole. During the rotation of the warping shaft, the end of the tungsten alloy wire can be fixed. Since the outer peripheral wall of the clamping member is coplanar with the outer peripheral wall of the warping shaft, the initial winding radius of the tungsten alloy wire can be the radius of the warping shaft. Compared with the binding and fixing method in the prior art, this application can reduce the impact of the tungsten alloy wire during the initial winding. Attached Figure Description

[0033] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] Please refer to the following: Figures 1 to 7 The present invention provides a slitting and warping device. The slitting and warping device includes a device body and a warping shaft 1 rotatably mounted on the device body. Both ends of the warping shaft 1 are connected to baffles 2. A plurality of strip-shaped holes 11 are spaced axially on the outer peripheral wall of the warping shaft 1, each strip-shaped hole 11 being used for insertion and engagement with the end of a tungsten alloy filament. The warping shaft 1 also includes a clamping member 3 for insertion and engagement with the strip-shaped holes 11. After insertion and engagement, the outer peripheral wall of the clamping member 3 is coplanar with the outer peripheral wall of the warping shaft 1. One side of the clamping member 3 engages with the side wall of the strip-shaped hole 11 to clamp the tungsten alloy filament within the strip-shaped hole 11. The clamping member 3 has a conical structure, and the strip-shaped hole 11 has a conical groove. This embodiment uses three strip-shaped holes 11 as an example.

[0035] The present invention provides a slitting and warping device. Compared with the prior art, by setting strip holes 11 on the warping shaft 1, a number of tungsten alloy wires are divided into groups corresponding to the number of strip holes 11. Each group of tungsten alloy wires is inserted into the corresponding strip hole 11, and the clamping member 3 is inserted into the strip hole 11 to clamp the end of the tungsten alloy wire in the strip hole 11. During the rotation of the warping shaft 1, the end of the tungsten alloy wire can be fixed. Since the outer peripheral wall of the clamping member 3 is coplanar with the outer peripheral wall of the warping shaft 1, the initial winding radius of the tungsten alloy wire can be the radius of the warping shaft 1. Compared with the binding and fixing method in the prior art, the present application can reduce the impact of the tungsten alloy wire during the initial winding.

[0036] It should be noted that the other mechanisms of the slitting and warping equipment are existing technologies and will not be described in detail here.

[0037] In some embodiments, such as Figures 1 to 7As shown, the sidewall of the clamping member 3 has an elastic layer 4, which is used to clamp the tungsten alloy wire in the strip hole 11; wherein, the opening of the strip hole 11 has an arc-shaped transition surface 12, and when the end of the tungsten alloy wire is fixed in the strip hole 11, the tungsten alloy wire can contact the arc-shaped transition surface 12.

[0038] It should be noted that the elastic layer 4 can be a rubber layer, which can be fixed to the side wall of the clamping member 3 by vulcanization process; by setting the rubber layer on the side wall of the clamping member 3, the rubber layer can undergo elastic deformation when clamping the tungsten alloy wire, thereby improving the clamping effect and reducing damage to the tungsten alloy wire.

[0039] For example, by providing a transition surface in the opening of the strip hole 11, the tungsten alloy wire comes into contact with the transition surface of the opening during the rotation of the warping shaft 1, which can make the tungsten alloy wire come into smooth contact with the opening and reduce the possibility of damage to the tungsten alloy wire.

[0040] In some embodiments, such as Figures 1 to 7 As shown, the outer peripheral wall of the abutment 3 is connected to an elastic cloth 5. The two ends of the elastic cloth 5 are fixed to the abutment 3, and the middle part of the elastic cloth 5 is attached to the outer peripheral wall of the abutment 3. The middle part of the elastic cloth 5 can be stretched outward so that a lifting space 51 is formed between the elastic cloth 5 and the abutment 3.

[0041] It should be noted that the elastic cloth 5 is relatively thin and elastic, therefore, setting the elastic cloth 5 on the outer peripheral wall of the clamping member 3 will not affect the tungsten alloy filament. When it is necessary to remove the clamping member 3 from the warping shaft 1, lifting the middle part of the elastic cloth 5 can create a lifting space 51 between the elastic cloth 5 and the outer peripheral wall of the warping shaft 1, which makes it easier for the operator to pull the clamping member 3 out of the warping shaft 1, and facilitates the reuse of the clamping member 3 and the warping shaft 1.

[0042] In some embodiments, such as Figures 1 to 7 As shown, the inner end of the abutment 3 is provided with an opening 31, and the opening 31 of the abutment 3 can be inserted and engaged with the tungsten alloy wire; wherein, after the tungsten alloy wire is inserted and engaged with the opening 31 of the abutment 3, the abutment 3 is inserted and engaged with the strip hole 11 to abut the tungsten alloy wire.

[0043] It should be noted that inserting the tungsten alloy wire into the inner end of the abutment 3 first, and then inserting the inner end of the abutment 3 into the strip hole 11, can improve the connection strength between the tungsten alloy wire and the warping shaft 1.

[0044] For example, the bottom wall of the strip hole 11 has an arc groove 13 for avoiding the tungsten alloy filament. By providing the arc groove 13 on the bottom wall of the strip hole 11, the curved part of the tungsten alloy filament can be avoided.

[0045] In some embodiments, such as Figures 1 to 7 As shown, the clamping member 3 has a clamping plate 32 inside the opening 31, and the side wall of the clamping member 3 has a threaded hole, and a set screw 6 is threaded in the threaded hole; wherein, when the tungsten alloy wire is inserted into the opening 31 of the clamping member 3, the clamping plate 32 is pressed against the tungsten alloy wire by the pushing action of the set screw 6.

[0046] It should be noted that after the tungsten alloy wire is inserted into the opening 31 of the clamping member 3, by rotating the set screw 6, the set screw 6 can push the clamping plate 32, thereby clamping the tungsten alloy wire in the clamping member 3, reducing the possibility of the tungsten alloy wire separating from the clamping member 3.

[0047] In some embodiments, such as Figures 1 to 7 As shown, the side wall of the abutment 3 has a receiving hole 33, and a limiting rod 34 is slidably disposed in the receiving hole 33. The inner wall of the strip hole 11 has an insertion hole 14, and the limiting rod 34 is inserted into the insertion hole 14. The limiting rod 34 is fitted with an elastic member 7, and the two ends of the elastic member 7 are respectively connected to the limiting rod 34 and the abutment 3. The abutment 3 has a reset structure, which is used to provide a pulling force to the limiting rod 34 so that the limiting rod 34 is separated from the insertion hole 14.

[0048] It should be noted that after the clamping member 3 is inserted into the strip hole 11, the limiting rod 34 on the clamping member 3 is aligned with the insertion hole 14 in the strip hole 11. Under the elastic force of the elastic member 7, the limiting rod 34 is in a through-insertion fit with the insertion hole 14. At this time, it can radially limit the clamping member 3 and prevent the clamping member 3 from separating from the warping shaft 1.

[0049] In addition, when one end of the limiting rod 34 is inserted into the insertion hole 14, the other end of the limiting rod 34 is located in the receiving hole 33 of the abutment 3, so the limiting rod 34 can play a radial limiting role on the abutment 3.

[0050] For example, by providing a reset structure on the abutment 3, the limiting rod 34 can be separated from the insertion hole 14, thereby facilitating the pulling of the abutment 3 from the warping shaft 1.

[0051] In some embodiments, such as Figures 1 to 7 As shown, the reset structure includes a pull rope 8, one end of which is connected to the inner end of the limiting rod 34, and the other end of which protrudes through the outer peripheral wall of the abutment 3. The outer peripheral wall of the abutment 3 has a clearance hole 35 for the pull rope 8 to pass through, and the protruding end of the pull rope 8 has a knot (not shown in the figure) located within the clearance hole 35. The clearance hole 35 is a stepped hole, and the knot is located at the larger diameter opening 31. The diameter of the knot is larger than the diameter of the smaller portion of the clearance hole 35.

[0052] It should be noted that by pulling the knotted part of the pull rope 8, the pull rope 8 can be pulled out, thereby causing the limiting rod 34 to slide in the receiving hole 33, and finally causing the limiting rod 34 to separate from the insertion hole 14; after the limiting rod 34 separates from the insertion hole 14, it is convenient for the operator to pull the abutment 3 outward, so that the abutment 3 separates from the warping shaft 1.

[0053] For example, the length of the pull rope 8 is greater than the sliding length of the limiting rod 34. Therefore, when the limiting rod 34 is inserted into the insertion hole 14, the pull rope 8 will not be completely located inside the receiving hole 33, so that the knot head is located outside the clamping member 3. After the clamping member 3 is inserted into place, the part of the pull rope 8 located outside the clamping member 3 is inserted into the clearance hole 35, so that the knot head is located at the opening 31 of the clearance hole 35. Therefore, the situation of the knot head protruding from the warping shaft 1 can be reduced. In the initial state, the clamping member 3 is located at the upper position of the warping shaft 1. When the warping shaft 1 starts to rotate, the speed is relatively slow. At this time, the tungsten alloy wire rotates in the direction of covering the clamping member 3. After the warping shaft 1 rotates at a preset angle, the initial tungsten alloy wire can cover the outer peripheral wall of the clamping member 3.

[0054] In addition, when the outer peripheral wall of the clamping member 3 has an elastic cloth 5 and a pull rope 8, after the knot of the pull rope 8 is placed into the clearance hole 35, the elastic cloth 5 can cover the clearance hole 35, so that the knot of the pull rope 8 is located inside the clearance hole 35, and the elastic cloth 5 can play a radial limiting role for the knot of the pull rope 8.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
