Description

Technical Field

[0001] This utility model relates to the field of automatic chain bending technology, specifically an automatic chain bending device for a chain braiding machine. Background Technology

[0002] A chain braiding machine is a specialized piece of machinery used for braiding high-strength lifting chains, industrial chains, and other chain links. Chain braiding machines are typically used to produce chains, which are generally metal links or rings. They are often used for mechanical transmission and traction, serving as chains to obstruct traffic or for mechanical transmission. Chains are used almost everywhere in daily life, and the increasing demand for chains has led to a gradual increase in the production capacity of chain braiding machines. When producing chains, the steel material needs to be cut and bent to facilitate the braiding process.

[0003] For example, Chinese patent CN218873511U discloses a bending and positioning mechanism for a chain braiding machine, which includes a base, a positioning device on the upper surface of the base, a bracket fixed on the upper surface of the base, a bending table fixed in the middle of the upper surface of the base, a bending assembly on the upper surface inside the bracket, a material receiving device on the upper surface of the base, a support plate fixed to the upper surface of the base, a cylinder fixed to the upper surface of the base, a support rod fixed to the front end of the support plate, a vertical rod fixed to the output end of the cylinder, and a connecting plate hinged to the upper surface of the vertical rod. The bending and positioning mechanism of this chain braiding machine can position the steel during bending to prevent it from shifting and affecting the bending effect, which would result in poor chain quality. A material collection device is also included to facilitate the collection of bent material. However, traditional automatic chain bending devices require cutting the bar material first, and then splicing the chain links after bending and closing the loop using auxiliary structures. This requires multiple auxiliary mechanisms, making the process complex and inefficient. Therefore, an automatic chain bending device for chain braiding machines is proposed to solve these problems.

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.

[0025] Please see Figure 1-4 The present invention provides the following technical solution: an automatic chain bending device for a chain braiding machine, comprising: a frame 1, wherein the outer surface of the frame 1 is fixedly mounted on a first slide 2, the first slide 2 is provided with an installation plate 21, and the installation plate 21 is slidably connected to a cutter 22, and the cutter 22 is fixedly mounted on the outer surface of one end of the installation plate 21; and a guide frame 3 is fixedly mounted on the outer surface of the frame 1, and the guide frame 3 is located below the first slide 2, and guides and conveys the bar material through the guide frame 3.

[0026] In this example, a first cam 24 is rotatably mounted on the outer surface of the frame 1 above the mounting plate 21. A first tension spring 25 is provided in front of the mounting plate 21. Connecting posts are provided at both ends of the first tension spring 25. The first cam 24 is driven to rotate by a motor, which drives the mounting plate 31 to slide down along the first slide 2. The bar material is cut by the cutter 22, and the cut bar material is bent along the module 23. During the downward sliding of the mounting plate, the first tension spring 25 will be stretched.

[0027] The bottom end of the cutter 22 is provided with a groove, and a module 23 is installed on the outer surface of the frame 1 below the groove. The module 23 is slidably connected to the frame 1. The module 23 is driven to retract inward and disengage from the chain link through the telescopic structure, so that the chain link can be removed.

[0028] In this embodiment, the second slide 4 is fixedly installed on the outer surface of the frame 1 and is located below the guide frame 3. The pressure plate 41 is slidably installed inside the second slide 4. The rocker arms 42 are rotatably installed on both sides of the outer surface of the frame 1. The outer surface of the rocker arms 42 is provided with a connecting rod 43. The outer surfaces of the rocker arms 42 and the pressure plate 41 are both fixedly installed with locking pins 44. The two ends of the connecting rod 43 are sleeved on the outer surface of the locking pins 44. After the bar is bent, the connecting rod 43 at one end of the rocker arm 42 pushes the pressure plate 41 along the second slide 4, so that one end of the pressure plate 41 pushes the bottom two sides of the bar upward to close the loop.

[0029] In this embodiment, arm 5 is positioned below the cutter 22. A guide shaft 51 is fixedly installed at the bottom end of the clamping arm 5. A guide seat 52 is sleeved on the outer surface of the guide shaft 51 and fixed to the outer surface of the frame 1. A cylinder 6 is fixedly installed at the bottom end of the outer surface of the frame 1. A connecting frame 61 is fixedly connected to one end of the output shaft of the cylinder 6, and the bottom end of the guide shaft 51 is rotatably connected to the connecting frame 61. The cylinder 6 pushes the guide shaft 51 upward along the guide seat 52, and the clamping arm 5 pushes and clamps the chain link.

[0030] The guide shaft 51 has a transmission gear 53 mounted on its outer surface. The front end of the frame 1 has a transmission plate 7, which is connected to the transmission gear 53 by meshing. One end of the transmission plate 7 is connected to a second tension spring 71, and the other end of the transmission plate 7 has a stop block 73 fixedly mounted on its outer surface. The outer surface of the transmission plate 7 has a guide groove 72. A second cam 74 is located on one side of the stop block 73 on the outer surface of the transmission plate 7. One end of the second cam 74 passes through the guide groove 72 and is rotatably connected to the outer surface of the frame 1. The second cam 74 drives the meshing teeth of the transmission plate 7 to drive the transmission gear 53 to rotate, thereby driving the clamping arm 5 to rotate and turn.

[0031] The working principle of this embodiment is as follows:

[0032] During processing, the bar stock is conveyed through the guide frame 3, and the first cam 24 is driven to rotate by the motor, causing the mounting plate 31 to slide down along the first slide 2. The bar stock is cut by the cutter 22, and the cut bar stock is bent along the module 23. During the downward sliding of the mounting plate, the first tension spring 25 will be stretched. When the first cam 24 moves to the other end, the cutter 22 will be pulled back, and so on.

[0033] After the bar stock is bent, the connecting rod 43 at one end of the rocker arm 42 pushes the pressure plate 41 along the second slide 4, so that one end of the pressure plate 41 pushes the bottom two sides of the bar stock upward to close the loop and form a chain link.

[0034] The cylinder 6 pushes the guide shaft 51 upward along the guide seat 52, and the clamping arm 5 pushes to clamp the chain link. At the same time, the telescopic structure drives the module 23 to retract inward and disengage from the chain link, making it easy to remove the chain link. Meanwhile, the second cam 74 drives the locking teeth of the transmission plate 7 to drive the transmission gear 53 to rotate, thereby driving the clamping arm 5 to rotate and turn. After turning, the clamping arm 5 is pushed upward by the cylinder 6 to lock the chain link into the bottom groove of the module 23, making it easy to connect to the next chain link. During the sliding process, one end of the transmission plate 7 will pull the second tension spring 71.
