Description

Technical Field

[0001] The present application relates to the technical field of slingshot line production, and in particular to a slingshot line shaping frame and a slingshot line production process. Background Art

[0002] The slingshot wire, also known as the spring wire or spiral wire, is a retractable connecting wire, which generally includes a TPU insulator and a metal wire. The insulator is injection molded and wrapped around the outside of the metal wire, and the slingshot wire has a spring portion similar to a spring structure.

[0003] Existing Chinese patent with publication number CN112695435A discloses a production process and equipment for slingshot wire, which includes the following steps: step 1, winding the slingshot wire on a winding rod; step 2, placing the winding rod in a baking chamber for baking; step 3, cooling the baked slingshot wire; step 4, reversing the cooled slingshot wire. The baking chamber is provided with a baking rack, a placement plate is fixedly provided on the baking rack, two placement plates are correspondingly provided on the baking rack, the winding rod is placed between the two placement plates, a plurality of winding rods are placed between the two placement plates, and a fixed block and a movable block are provided on the winding rod.

[0004] With regard to the above-mentioned related technologies, in the process of making slingshot wires, after the outer side of the metal wire is injection molded, the wire needs to be wound on the winding rod, and then the two ends of the wound slingshot wire are restricted by fixed blocks and movable blocks to prevent the slingshot wire from spreading. The winding rod is then placed on a baking rack and finally sent into an oven for baking and shaping. Finally, the slingshot wire is reversed and removed from the winding rod to complete the preparation.

[0005] However, if Figure 1 As shown, the slingshot line generally includes a spring portion 1 and a straight portion 2, and the straight portion 1 is integrally connected to the two ends of the spring portion 2. When the cable is wound around the winding rod and the two ends of the preliminarily formed slingshot line are positioned by the fixed block and the moving block, the straight portions 2 at both ends of the slingshot line are nearly perpendicular to the winding rod, so the straight portion 2 that is reversed after drying is also nearly perpendicular to the length direction of the spring portion 1. In some special usage scenarios, it is sometimes necessary to ensure that the straight portion 2 and the spring portion 1 are kept on the same straight line or at a certain angle to facilitate wiring, but the existing slingshot line production equipment cannot meet the production of multiple angles between the spring portion 1 and the straight portion 2. Summary of the invention

[0006] In order to facilitate the adjustment of the angle between the spring portion and the straight portion and improve applicability, the present application provides a slingshot line forming frame and a slingshot line production process.

[0007] In the first aspect, the present application provides a slingshot line shaping frame adopting the following technical solution: A slingshot line shaping frame comprises a frame body and a plurality of winding rods, wherein the winding rods are provided with positioning blocks, the positioning blocks are slidably adjusted along the length direction of the winding rods, the positioning blocks abut against two ends of the predetermined slingshot line, the winding rods are horizontally arranged in a row on the frame body, and the positions of the frame body near the two ends of the slingshot line are provided with adjusting components, and the adjusting components are used to press the straight line part and adjust the angle of the straight line part; wherein, the adjusting component comprises a support plate and a pressure plate, the support plate is arranged along the horizontal direction and is perpendicular to the length direction of the winding rod, the support plate is slidably adjusted along the height direction, the pressure plate is arranged opposite to the support plate up and down, the pressure plate cover is arranged on the upper surface of the support plate, the straight line part is pressed between the support plate and the pressure plate, the support plate comprises a rotating module for rotation adjustment, the rotating module is rotationally adjusted in a horizontal plane, and the rotating axis of the rotating module is horizontally arranged and perpendicular to the length direction of the winding rod.

[0008] By adopting the above technical scheme, the cable is wound around the winding rod to form a preformed slingshot line, and the two ends of the preformed spring part are fixed by the positioning block, and then the winding rods are horizontally spaced and placed in rows on the frame; the support plate is rotated to adjust the required horizontal angle, and the support plate is moved down to a position close to the two ends of the spring part, so that the support plate is located above one end close to the spring part, and then the straight part is pressed down by the pressing plate, and each straight part is clamped between the upper surface of the support plate and the pressing plate. At this time, the straight part and the spring part form a certain angle, and the angle is close to the horizontal plane inclination angle of the rotating module; finally, the frame is transported to the baking oven for baking and shaping. At this time, the straight part and the spring part are baked and shaped at a certain angle, and the angle between the straight part and the spring part can be adjusted by the support plate, so that the angle between the formed spring part and the straight part meets the requirements, and the angle between the spring part and the straight part is easy to adjust, thereby improving the effect of applicability.

[0009] Preferably, a guide rod is vertically arranged on the frame body, the guide rod passes through one end of the support plate, an adjusting nut is threadedly connected to the guide rod, and the adjusting nut is supported on the lower surface of the support plate.

[0010] By adopting the above technical solution, the pallet can slide up and down along the guide rod, and the adjusting nut can support the pallet and limit the downward sliding of the pallet, thereby realizing the height adjustment of the pallet, so that the pallet can be closer to the top of the winding rod and the slingshot line, ensuring that when the straight part is pressed against the upper surface of the pallet, the angle between the straight part and the spring part is closer to the inclination angle of the pallet.

[0011] Preferably, a groove is provided on the side wall of the upper end of the guide rod, and an elastic member which can be extended and retracted in the horizontal direction is provided at the bottom of the groove.

[0012] By adopting the above technical solution, since the winding rod needs to be placed on the frame, when placing it, if the support plate is too close to the winding rod, it will affect the normal placement efficiency of the winding rod. At this time, the support plate can be moved upward so that the positioning pin is supported under the support plate, so that there is enough space between the placement position of the winding rod and the support plate; when the support plate needs to be used, the positioning pin is pressed horizontally to compress the elastic part, and the positioning pin shrinks into the groove, so that the support plate can be moved downward and supported by the adjusting nut.

[0015] Preferably, a vertical rod is vertically arranged on the upper surface of the rotating module, and the vertical rod passes through the pressing plate.

[0016] By adopting the above technical solution, the vertical rod passes through the pressure plate, which can limit the pressure plate, so that the pressure plate can move in the height direction, and the pressure plate can move up and down stably above the rotating module. Since the pressure plate has a certain weight, when the external force on the pressure plate is removed, the pressure plate can slide down by itself and press the straight parts.

[0017] Preferably, a counterweight frame is provided on the upper surface of the pressure plate, and a plurality of counterweight blocks are provided in the counterweight frame.

[0018] By adopting the above technical solution, the counterweight frame and the counterweight block can adjust the pressure of the pressure plate on the straight part to ensure that each straight part can be bent on the upper surface of the rotating module.

[0019] Preferably, the surfaces of the rotating module and the pressing plate are wrapped with a flexible layer.

[0020] By adopting the above technical solution, the flexible layer has a certain buffering effect, and when the straight portion is pressed between the rotating module and the pressing plate, the extrusion deformation of the outer contour of the straight portion itself can be reduced.

[0024] By adopting the above technical solution, the placement frame can realize the placement of multiple layers of winding rods on the frame, and the positioning grooves can position the winding rods, thereby improving the stability of the positioning rods placed on the placement frame.

[0025] In a second aspect, the present application provides a slingshot line production process for the above-mentioned calibrating frame, which adopts the following technical solution: A slingshot line production process comprises: winding a cable around a winding rod to form a preformed slingshot line, fixing the two ends of the preformed spring part by means of a positioning block, and then placing the winding rods in rows and at intervals horizontally on a frame; slidingly adjusting the position and horizontal angle of a support plate so that the support plate is located above one end close to the spring part, and then pressing down the straight part by means of a pressing plate, clamping each straight part between the upper surface of the support plate and the pressing plate, at which time the straight part and the spring part form a certain angle; conveying the frame to a baking oven for baking and shaping; cooling the slingshot line after baking and shaping, and finally reversing and removing the slingshot line from the winding rod.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 2-7 This application is described in further detail.

[0030] The present application embodiment discloses a slingshot line shaping frame, which is mainly used for the production of slingshot lines. Figure 2 and Figure 3The shaping frame includes a frame body 3, a plurality of winding rods 4 and an adjustment assembly 5. At least one placement frame 6 is fixed to the frame body 3 at intervals along the height direction. In this embodiment, the placement frame 6 is rectangular and three are provided. Positioning grooves 7 are provided at intervals on the upper surface of the long side of the placement frame 6. The two ends of each winding rod 4 are respectively overlapped in the positioning grooves 7 on the long side of the placement frame 6. The positioning grooves 7 can limit the winding rods 4 to a certain extent, so that the winding rods 4 can be arranged in rows and multiple layers.

[0031] A stop edge 8 is vertically fixed to the outer contour of the surrounding side of the placement frame 6, and the stop edge 8 can block the end of the positioning groove 7 close to the outer edge of the placement frame 6, thereby limiting the winding rod 4 from sliding away from the placement frame 6 in its own length direction, and further ensuring the stability of the winding rod 4 when placed on the placement frame 6.

[0032] Two positioning blocks 9 are sleeved on each winding rod 4. The positioning blocks 9 are slidably adjusted along the length direction of the winding rod 4, and a tightening bolt 10 is threadedly connected to the side wall of the positioning block 9, and one end of the tightening bolt 10 is tightened against the outer side of the winding rod 4; when the cable is wound on the winding rod 4, the position of the positioning block 9 can be slidably adjusted so that the positioning block 9 abuts against the two ends of the predetermined spring part 1, and then the tightening bolt 10 is rotated to keep the position of the positioning block 9 stable, so as to tighten the two ends of the spring part 1 and prevent the spring part 1 that has not been heated and finalized from loosening.

[0033] The adjusting assembly 5 is arranged on the frame 3 and above each layer of the placing frames 6. Two placing frames 6 are arranged above each layer of the placing frames 6. The adjusting assembly 5 is used to press the straight portion 2 and adjust the angle of the straight portion 2 to shape the angle between the straight portion 2 and the spring portion 1 before baking. The adjusting assembly 5 is located near both ends of the slingshot line, and each adjusting assembly 5 presses multiple straight portions 2 at the same end of each row of slingshot lines.

[0034] Reference Figure 3 and Figure 4 The adjustment assembly 5 includes a support plate 51 and a pressure plate 52. The support plate 51 is arranged in the horizontal direction and perpendicular to the length direction of the winding rod 4. The support plate 51 is arranged to slide and adjust in the height direction. The pressure plate 52 is arranged opposite to the support plate 51 in the vertical direction. The pressure plate 52 is covered on the upper surface of the support plate 51. A vertical rod 11 is vertically fixed on the upper surface of the support plate 51. The cross section of the vertical rod 11 is square. The vertical rod 11 passes through the pressure plate 52, so that the pressure plate 52 can stably slide on the support plate 51, and the pressure plate 52 and the support plate 51 can be opened.

[0035] Reference Figure 4 and Figure 5The support plate 51 includes a fixed portion 511 and a rotation module 512 for rotation adjustment. The rotation module 512 and the fixed portion 511 are both in the shape of strips. The fixed portion 511 is connected to the frame body 3 for sliding adjustment. The rotation module 512 is rotationally adjusted and arranged on the fixed portion 511. The rotation module 512 is rotationally adjusted and arranged on a horizontal plane. The rotation axis of the rotation module 512 is horizontally arranged and perpendicular to the length direction of the winding rod 4. An extension plate 25 is fixed on the long side of the fixed portion 511. The extension plate 25 is located below the fixed portion 511. A cross bar 12 is horizontally fixed to the lower end of the extension plate 25. The cross bar 12 is perpendicular to the length direction of the winding rod 4. External threads are processed on the outer sides of both ends of the cross bar 12. Hinge pieces 13 are horizontally fixed at both ends of the rotating module 512 in the length direction, and both ends of the cross bar 12 pass through the hinge pieces 13 and are threadedly connected to one of the hinge pieces 13, that is, only one hinge piece 13 passes through the hole wall of the cross bar 12 and is processed with an internal thread, and the hole wall of the other hinge piece 13 is a smooth surface; locking nuts 14 are threadedly connected at both ends of the cross bar 12. After the horizontal inclination of the rotating module 512 is adjusted by rotation, the locking nut 14 can be rotated so that one side of the locking nut 14 is pressed against the side of the two hinge pieces 13 that are away from each other, thereby limiting the rotation of the rotating module 512, thereby realizing the angle adjustment of the rotating module 512 with the cross bar 12 as the rotating axis.

[0036] Reference Figure 4 and Figure 6 When in use, the rotating module 512 moves downward simultaneously with the fixing portion 511 until the lower long side end of the rotating module 512 approaches or contacts the spring portion 1, and at the same time the pressing plate 52 moves downward to bend the straight portion 2, and finally presses the straight portion 2 onto the upper surface of the supporting plate 51. At this time, the angle between the rotating module 512 and the plane is close to the angle between the straight portion 2 and the spring portion 1, and the requirements for forming different angles between the straight portion 2 and the spring portion 1 can be met by controlling the angle of the rotating module 512.

[0037] A guide rod 15 is vertically fixed on the frame body 3, and the guide rod 15 passes through a position near the middle of the fixing portion 511. An adjusting nut 16 is threadedly connected to the guide rod 15, and the adjusting nut 16 is supported on the lower surface of the support plate 51. By rotating the height of the adjusting nut 16, the height of the support plate 51 can be adjusted when in use.

[0038] Moreover, the extension plate 25 can make the rotating module 512 located below one side of the fixing portion 511, so that the lower end of the guide rod 15 and the adjusting nut 16 can be located higher than the plane where the winding rod 4 is arranged, which is convenient for height adjustment of the support plate 51. The extension plate 25 is provided with a strip hole 17 in the length direction. When the straight portion 2 is long, the straight portion 2 pressed on the support plate 51 can pass through the strip hole 17 without being interfered by the extension portion, thereby ensuring the normal extension of the straight portion 2.

[0039] In some embodiments, a groove 18 is provided on the side wall of the upper end of the guide rod 15, and an elastic member 19 that is retracted and reset in the horizontal direction is fixed at the bottom of the groove 18. The elastic member 19 is selected to be a spring or a rubber column, and a positioning pin 20 is fixed to the end of the elastic member 19 away from the bottom of the groove 18; when the elastic member 19 is in a natural state, one end of the positioning pin 20 is located outside the groove 18. When placing the winding rod 4, the support plate 51 can be moved upward until the fixing portion 511 is higher than the height of the positioning pin 20. The positioning pin 20 is supported on the lower surface of the support plate 51, and the downward sliding of the support plate 51 can be limited, so that there is a certain space between the support plate 51 and the placement position of the winding rod 4, which is convenient for the rapid placement of the winding rod 4. When the support plate 51 is needed, the positioning pin 20 is pressed and retracted into the groove 18, and the support plate 51 can move downward until the adjustment nut 16 is supported on the lower surface of the fixing portion 511.

[0040] In some embodiments, reference Figure 5 and Figure 7 A counterweight frame 21 is fixed near the middle of the upper surface of the pressure plate 52, and a plurality of counterweight blocks 22 are placed in the counterweight frame 21. The pressure of the pressure plate 52 on the lifting straight part 2 can be adjusted by the number of the counterweight blocks 22.

[0041] In some embodiments, reference Figure 4 The surfaces of the rotating module 512 and the pressing plate 52 are wrapped with a flexible layer 23 . The flexible layer 23 is made of cloth or sponge, which can reduce the wear on the slingshot line.

[0042] In some embodiments, reference Figure 1 and Figure 2 A slider is fixed on the upper end of the guide rod 15, and a slide rail 24 is horizontally installed on the frame 3. The length direction of the slide rail 24 is parallel to the length direction of the winding rod 4. The slider is slidably connected to the slide rail 24, so as to facilitate the adjustment of the position of the support plate 51 in the length direction of the winding rod 4. Since the lengths of the spring parts 1 of different slingshot lines are inconsistent, in order to ensure that the side of the rotating module 512 away from the fixed part 511 can be close to the end of the spring part 1, the position of the support plate 51 in the length direction of the winding rod 4 can be horizontally adjusted, thereby ensuring that the support plate 51 can be moved to a position close to both ends of the spring part 1, so as to adapt to slingshot lines with different lengths of the spring part 1, thereby improving applicability.

[0043] The implementation principle of a slingshot line shaping frame of the present application embodiment is as follows: the cable is wound on the winding rod 4 by a winding machine, and then the two ends of the spring part 1 are pressed by two positioning blocks 9, and the two straight parts 2 are oriented in the same direction, and then the winding rods 4 are neatly arranged in a row in the placement frame 6, and the straight parts 2 are oriented upward. According to the angle requirement between the straight part 2 and the spring part 1, the tightening nut 14 is loosened, and the horizontal inclination of the rotating module 512 is rotated to adjust the inclination of the rotating module 512 to the required angle between the straight part 2 and the spring part 1, and then the height of the support plate 51 is controlled by adjusting the height position of the nut 16 until the lower end of the rotating module 512 is close to the end of the spring part 1, and finally the pressing plate 52 is moved down and pressed on the straight part 2, and the straight part 2 is pressed by the gravity of the pressing plate 52 itself and the counterweight 22, so that the straight part 2 and the spring part 1 are bent into the required angle, and then dried and shaped, so as to facilitate the adjustment of the angle between the spring part 1 and the straight part 2 and improve the applicability.

[0044] The present application also discloses a slingshot line production process for the above-mentioned calibrating frame, comprising: The cable is wound around the winding rod 4 to form a preformed slingshot line, and the two ends of the preformed spring part 1 are fixed by the positioning block 9, and then the winding rod 4 is horizontally spaced and placed in a row on the frame 3; The position and horizontal angle of the support plate 51 are adjusted by sliding so that the support plate 51 is located above one end close to the spring portion 1, and then the straight portion 2 is pressed down by the pressing plate 52 to clamp each straight portion 2 between the upper surface of the support plate 51 and the pressing plate 52. At this time, the straight portion 2 and the spring portion 1 form a certain angle; The frame 3 is transported to a baking oven for baking and shaping; After baking and shaping, the slingshot line is cooled, and finally the slingshot line is reversed and removed from the winding rod 4.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
