Description

Technical Field

[0001] This utility model relates to the field of wire rope forming mold technology, and in particular to a wire rope forming mold for adjusting the tension of multiple strands. Background Technology

[0002] A wire rope forming die is a specialized piece of equipment used in the production of wire ropes. Through a specific die structure and process, it ensures that the wire rope is formed into a predetermined shape during production. Tension control of the strands is crucial in the wire rope production process. The forming process requires maintaining balanced tension in each layer of strands during the parallel winding of multiple strands to ensure the final product has good physical properties and a long service life. However, due to the dynamic changes in the strands after entering the forming die, uneven tension often occurs. Therefore, a multi-layer wire rope forming die with balanced strand tension is needed.

[0003] The multi-layer strand tension equalization adjustment wire rope forming die is a piece of equipment specially designed for the production of multi-layer wire ropes. In traditional technology, wire rope forming dies often use fixed tension control devices for tension adjustment, which are difficult to adapt to the dynamic changes in strand tension during the production process, thus affecting the use of the forming die. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-layer strand tension equalization adjustment wire rope forming mold, which aims to improve the problem that wire rope forming molds often use fixed tension control devices for tension adjustment, making it difficult to adapt to the dynamic changes in strand tension during the production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-layer strand tension equalization adjustment wire rope forming mold includes a worktable. A lower mold is fixedly connected to the upper surface of the worktable. A conveyor frame is fixedly connected to the outer wall of the lower mold. A fixed frame is fixedly connected to the upper surface of the lower mold. A hydraulic cylinder is fixedly connected inside the fixed frame. An upper mold is fixedly connected to the output end of the hydraulic cylinder. A guide frame is provided inside the worktable. A fixed seat is fixedly connected to the upper surface of the worktable. A motor is fixedly connected to the outer wall of the fixed seat.

A fixed rod is slidably connected inside the adjusting frame. The bottom end of the fixed rod is fixedly connected to the inside of the fixed seat. An adjusting assembly is provided inside the upper mold.

[0007] The above technical solution involves: Conveying frames fixed on both sides of the lower mold to facilitate the movement of the strand between the lower and upper molds, while also limiting the deviation of the strand's movement; rollers installed inside the guide frame, adjusting frame, and conveying frame, matching the processed strand, to limit the strand's movement; grooves opened inside both the lower and upper molds, matching the processed strand, to facilitate extrusion and auxiliary forming of the strand; a fixed base to fix the fixing rod, which in turn limits the range of movement of the adjusting frame; and the cooperation of bevel gear one and bevel gear two to facilitate motor transmission of the lead screw.

[0008] Preferably, the adjusting component includes a hydraulic rod, the outer wall of which is fixedly connected to the inside of the upper mold, the output end of which passes through the inside of the upper mold and is fixedly connected to an arc-shaped block, the outer wall of which is slidably connected to the inside of the upper mold.

[0009] The above technical solution achieves the effect of fixing the hydraulic rod through the inside of the upper mold, and also restricts the movement of the arc block through the inside of the upper mold.

[0010] Preferably, the bottom end of the lead screw is rotatably connected to the inside of the fixed base, the outer wall of the adjusting frame is slidably connected to the inside of the fixed base, and the inside of the upper mold is slidably connected to the outer wall of the fixed frame.

[0011] The above technical solution facilitates the transmission of the adjusting frame as the lead screw rotates, and the lower middle side of the adjusting frame matches the interior of the fixed base, which helps to move the adjusting frame.

[0012] Preferably, an L-shaped frame is slidably connected inside the workbench, and a transmission seat is fixedly connected to the outer wall of the L-shaped frame.

[0013] The above technical solution restricts the movement of the L-shaped frame by means of the inside of the worktable, which facilitates the transmission of the transmission seat when the L-shaped frame is pushed or pulled.

[0014] Preferably, the outer wall of the transmission seat is slidably connected to the inside of the worktable, and a connecting frame is rotatably connected to the outer wall of the transmission seat.

[0015] The above technical solution involves limiting the movement of the transmission seat by having both the upper and lower outer walls slide inside the worktable, thereby driving the connecting frame as the transmission seat moves.

[0016] Preferably, a U-shaped seat is rotatably connected to the outer wall of the connecting frame, and a convex frame is fixedly connected to the outer wall of the U-shaped seat.

[0017] The above technical solution facilitates the transmission of the U-shaped seat as the connecting frame moves.

[0018] Preferably, the outer wall of the convex frame is slidably connected to the inside of the worktable, and the outer wall of the convex frame is disposed inside the guide frame.

[0019] The above technical solution involves moving the U-shaped seat, which slides in and out inside the guide frame, thereby limiting or releasing the guide frame.

[0020] Preferably, the outer wall of the convex frame is slidably connected to the inside of the worktable, and the outer wall of the convex frame is disposed inside the guide frame.

[0021] The above technical solution involves compressing or releasing the spring as the convex frame moves, thereby limiting the range of movement of the convex frame using the spring.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a wire rope forming mold for multi-layer strand tension equalization adjustment, including a workbench 1, a lower mold 2 fixedly connected to the upper surface of the workbench 1, a conveyor frame 3 fixedly connected to the outer wall of the lower mold 2, a fixed frame 4 fixedly connected to the upper surface of the lower mold 2, a hydraulic cylinder 5 fixedly connected inside the fixed frame 4, an upper mold 6 fixedly connected to the output end of the hydraulic cylinder 5, a guide frame 14 provided inside the workbench 1, a fixed seat 7 fixedly connected to the upper surface of the workbench 1, a motor 8 fixedly connected to the outer wall of the fixed seat 7, a bevel gear 9 fixedly provided at the output end of the motor 8 through the interior of the fixed seat 7, a bevel gear 10 meshing with the tooth end of the bevel gear 19, a lead screw 11 fixedly connected inside the bevel gear 10, an adjusting frame 12 threadedly connected to the outer wall of the lead screw 11, a fixed rod 13 slidably connected inside the adjusting frame 12, the bottom end of the fixed rod 13 fixedly connected to the interior of the fixed seat 7, and an adjusting assembly provided inside the upper mold 6.

[0034] Specifically, the outer wall of the fixed rod 13 and the interior of the fixed seat 7 facilitate the smooth movement of the adjusting frame 12. The adjusting frame 12 consists of a hollow sleeve and a roller frame. The movement of the hollow sleeve allows the roller frame to adjust the tension of the strands before entering the mold. The hydraulic cylinder 5 is a common feature in the prior art, so it will not be described in detail here. The motor 8 is a feature with a self-locking device, which is connected to the thread between the adjusting frame 12 and the lead screw 11 to prevent accidental movement of the adjusting frame 12. An adjusting component is provided inside the upper mold 6. The adjusting component and the motor 8 are connected to existing control equipment. At the same time, a tension sensor is installed in the mold to adjust the tension of the strands before entering the mold and also to adjust the tension of the strands in the mold, ensuring tension balance during the molding process.

[0035] Reference Figure 3 The adjustment component includes a hydraulic rod 15, the outer wall of which is fixedly connected to the inside of the upper mold 6, the output end of which passes through the inside of the upper mold 6 and is fixedly connected to an arc block 16, the outer wall of which is slidably connected to the inside of the upper mold 6.

[0036] Specifically, by connecting the hydraulic rod 15 to a PLC, controller, or other existing equipment, it is convenient to control the movement of the arc block 16 inside the upper mold 6, thereby facilitating the tension adjustment of the strands in contact with the upper mold 6.

[0037] Reference Figure 2 The bottom end of the lead screw 11 is rotatably connected to the inside of the fixed base 7, the outer wall of the adjusting frame 12 is slidably connected to the inside of the fixed base 7, and the inside of the upper mold 6 is slidably connected to the outer wall of the fixed frame 4.

[0038] Specifically, the rotation of the lead screw 11 is supported and limited by the interior of the fixed seat 7, the movement of the adjusting frame 12 is offset by the interior of the fixed seat 7, and the movement of the upper mold 6 is offset by the outer wall of the fixed frame 4.

[0039] Reference Figure 4 and Figure 5 An L-shaped frame 17 is slidably connected inside the worktable 1, and a transmission seat 18 is fixedly connected to the outer wall of the L-shaped frame 17. The outer wall of the transmission seat 18 is slidably connected inside the worktable 1, and a connecting frame 19 is rotatably connected to the outer wall of the transmission seat 18. A U-shaped seat 20 is rotatably connected to the outer wall of the connecting frame 19, and a convex frame 21 is fixedly connected to the outer wall of the U-shaped seat 20. The outer wall of the convex frame 21 is slidably connected inside the worktable 1, and the outer wall of the convex frame 21 is located inside the guide frame 14. A spring 22 is fixedly connected to the outer wall of the convex frame 21, and the outer wall of the spring 22 is fixedly connected to the inside of the worktable 1.

[0040] Specifically, the movement range of the L-shaped frame 17 is limited by the interior of the workbench 1. A short rod is provided inside the transmission seat 18 and connected to the connecting frame 19. A short rod is also provided inside the connecting frame 19 and connected to the U-shaped seat 20, so that the transmission seat 18 can transmit power to the U-shaped seat 20 through the connecting frame 19. The movement of the convex frame 21 is limited by the interior of the workbench 1. The two ends of the spring 22 are connected to the convex frame 21 and the workbench 1 respectively. Without the action of external force driving the L-shaped frame 17, the spring 22 itself holds the convex frame 21, providing support for the convex frame 21 inside the guide frame 14, thereby improving the stability of the guide frame 14 installation.

[0041] Working principle: When using this mold, multiple layers of strands are placed in the rollers of the guide frame 14. The feeding mechanism pushes the strands through the rollers of the guide frame 14, the adjusting frame 12, and the conveying frame 3, and then into the space between the lower mold 2 and the upper mold 6. The motor 8 drives the first bevel gear 9 to rotate, which in turn drives the second bevel gear 10 to rotate the lead screw 11 inside the fixed base 7. The thread between the adjusting frame 12 and the lead screw 11 causes the adjusting frame 12 to move upward inside the fixed base 7. The movement of the adjusting frame 12 is controlled by the fixed rod 13. The limit switch, when the adjusting frame 12 moves upward, makes the strands inside the adjusting frame 12 form a height difference with the strands in other directions, thereby adjusting the tension of the strands entering between the lower mold 2 and the upper mold 6. As the strands are between the lower mold 2 and the upper mold 6, the hydraulic cylinder 5 pushes the upper mold 6 to move downward, so that the strands of the upper mold 6 are extruded to assist in forming. At the same time, the hydraulic rod 15 and the arc block 16 inside the upper mold 6 dynamically adjust the tension of the strands between the upper mold 6 and the lower mold 2. Finally, the strands are discharged from the left side of the lower mold 2 and the upper mold 6 for subsequent processing.

[0042] By pushing the L-shaped frame 17, the transmission seat 18 is moved to the left. Through the connecting frame 19, the U-shaped seat 20 is moved towards the L-shaped frame 17, thereby causing the U-shaped seats 20 on both sides to move towards the L-shaped frame 17. This, in turn, causes the convex frames 21 on both sides to move towards the L-shaped frame 17, compressing the spring 22. The convex frame 21 slides out of the interior of the guide frame 14, no longer limiting the guide frame 14, making it easy to remove the guide frame 14. During use, this mold not only adjusts the tension of the strands but also enables quick installation and disassembly of the guide frame 14, facilitating cleaning and maintenance.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
