However, existing wavy bending and pressing forming devices for wire harness supports have some shortcomings, such as:

[0003] The automotive wiring harness bracket corrugated bending forming mold described in application number CN202310732895.7 has a complex structure due to the fact that the equipment is composed of multiple parts. This not only increases the manufacturing and maintenance costs of the equipment, but also involves multiple moving parts and complex linkage mechanisms. It requires high manufacturing and assembly precision for each part, and the subsequent precision adjustment and maintenance are quite difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a wavy bending and pressing forming device for wire harness brackets, so as to solve the problem mentioned in the background art that the existing equipment on the market consists of multiple parts and has a relatively complex structure, which not only increases the manufacturing and maintenance costs of the equipment, but also involves multiple moving parts and complex linkage mechanisms, requiring high manufacturing and assembly precision for each part, and making subsequent precision adjustment and maintenance difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire harness bracket wave-shaped bending and pressing forming device, comprising a support frame, a guide rod, a first motor, a lead screw, and a second spring;

[0006] The side of the support frame is provided with a feeding mechanism, which includes a second motor, a pusher roller, a second bolt, a fixing plate, and a second spring. The second motor serves as a power output unit and drives the pusher roller to rotate. When the raw material enters the conveying channel, the second spring installed on the outer ring of the second bolt generates an elastic thrust, which pushes the fixing plate to drive the pusher roller to fit tightly against the surface of the raw material.

[0007] A forming mechanism is set at the center line of the support frame. The forming mechanism includes a first motor, a first roller frame, an extrusion block, a second roller frame, a first bolt, a drive shaft, a first spring, a support block, a gasket, and a positioning block. The first roller frame and the second roller frame have the same structure and are meshed like gears. The extrusion blocks installed on the outer side of the first roller frame and the second roller frame extrude alternately, and the raw material is bent and pressed into shape under the push of the drive shaft and the first motor.

[0008] As a preferred technical solution of this utility model, there are two feeding mechanisms arranged symmetrically, and the second bolt in the feeding mechanism is threadedly connected to the bearing frame. There are four second bolts arranged in a rectangle, and the inner side of the second bolt is slidably connected to the fixing plate. The fixing plates are rotatably connected to the push rollers. There are eight push rollers in two rows of four. The input shaft above the push roller is fixedly connected to the second motor. A second spring is sandwiched between the second bolt and the fixing plate.

[0009] The above technical solution features two symmetrically arranged feeding mechanisms. This symmetrical structure ensures more uniform force distribution on the raw materials during transport. The second bolt in the feeding mechanism is threadedly connected to the support frame, facilitating installation and adjustment. Four second bolts are arranged in a rectangular pattern, with a fixed plate slidably connected to their inner sides. Push rollers are rotatably connected between the fixed plates, forming a group of eight push rollers in two rows of four. The input shaft above the push rollers is fixedly connected to a second motor, ensuring sufficient friction for transporting the raw materials. A second spring is sandwiched between the second bolts and the fixed plates. The spring's elasticity adapts to raw materials of varying thicknesses, enhancing the equipment's versatility.

[0010] As a preferred technical solution of this utility model, the surface of the support frame is vertically fixed with guide rods, and there are eight guide rods in total, which are distributed in both directions. A first roller frame is installed above the guide rods, and the first roller frame and the second roller frame have the same overall structure. The outer ring of the first roller frame and the second roller frame are bolted to the extrusion block.

[0011] Using the above technical solution, eight guide rods are vertically fixed on the surface of the support frame. These guide rods are distributed in both directions to provide precise guidance for the movement of the first and second roller frames, ensuring the stability of the molding process. The first roller frame is installed above the guide rods, and the second roller frame is installed below the guide rods. The second roller frame has the same overall structure, ensuring the consistency of the forces applied to the upper and lower parts during the molding process.

[0012] As a preferred embodiment of this utility model, the second roller frame is fitted onto the outer ring of the drive shaft, and the drive shaft has a hexagonal structure. The left side of the drive shaft is threadedly connected to a first bolt, and four washers are placed sequentially between the first bolt and the second roller frame. The right side of the second roller frame is fitted to a positioning block, and the positioning block is slidably connected to the drive shaft. The side of the positioning block is fixedly connected to one end of a first spring, and the other end of the first spring is fixedly connected to the drive shaft. The input shaft of the drive shaft is fixedly connected to a first motor, and the first motor is fixedly connected to a bearing block. A lead screw is threadedly connected to the surface of the bearing block.

[0013] Using the above technical solution, the second roller frame is fitted onto the outer ring of the drive shaft, and the drive shaft has a hexagonal structure. This special structure can effectively prevent relative rotation between the second roller frame and the drive shaft, ensuring stable power transmission. The left side of the drive shaft is threadedly connected to a first bolt, and four washers are placed between the first bolt and the second roller frame to adjust the axial position of the second roller frame. The right side of the second roller frame is fitted with a positioning block, and the positioning block is slidably connected to the drive shaft. The side of the positioning block is fixedly connected to one end of a first spring, and the other end of the first spring is fixedly connected to the drive shaft. The first spring can play a role in buffering and fine-tuning, avoiding damage to the raw materials or equipment due to excessive pressure. The input shaft of the drive shaft is fixedly connected to a first motor, and the first motor is fixedly connected to a bearing block. A lead screw is threadedly connected to the surface of the bearing block.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figures 1-6 The present invention provides a wavy bending and pressing forming device for a wire harness bracket, comprising a support frame 1, a guide rod 2, a first motor 3, a lead screw 4, a second motor 5, a pusher roller 6, a first roller frame 7, an extrusion block 8, a second roller frame 9, a first bolt 10, a drive shaft 11, a first spring 12, a support block 13, a gasket 14, a positioning block 15, a second bolt 16, a fixing plate 17, and a second spring 18.

[0030] Two feeding mechanisms are symmetrically arranged on the side of the support frame 1. This design is crucial because it ensures that the raw materials are evenly stressed during the conveying process, thus ensuring the stability of the conveying.

[0031] The feeding mechanism is mainly composed of a second motor 5, a pusher roller 6, a second bolt 16, a fixing plate 17, and a second spring 18. The second motor 5 serves as the power core, providing power for the entire feeding process and driving the pusher roller 6 to rotate.

[0032] The second bolt 16 plays an important role in the feeding mechanism. It is connected to the support frame 1 by a thread. This connection method is not only easy to install, but also convenient for the feeding mechanism to be adjusted later. There are four second bolts 16 in total, arranged in a rectangle. Their inner side is slidably connected to the fixing plate 17. Between the fixing plates 17, the pusher rollers 6 are rotatably connected. There are two rows of pusher rollers 6, four in each row, for a total of eight. The upper input shaft of these pusher rollers 6 is fixedly connected to the second motor 5. This layout ensures that the pusher rollers 6 can obtain sufficient power and generate sufficient friction, thereby stably conveying raw materials.

[0033] It is worth mentioning that a second spring 18 is also sandwiched between the second bolt 16 and the fixing plate 17. When the raw material enters the conveying channel, the second spring 18 exerts its elastic effect to generate elastic thrust, push the fixing plate 17, and then drive the pusher roller 6 to fit tightly against the surface of the raw material. The ingenuity of this design is that it can adapt to raw materials of different thicknesses, greatly enhancing the versatility of the equipment. No matter how the thickness of the raw material changes, it can ensure a stable conveying effect.

[0034] At the centerline position of the support frame 1, a forming mechanism is set. It is the key part to realize the wave-shaped bending and pressing forming of the wire harness bracket. The forming mechanism includes a first motor 3, a first roller frame 7, an extrusion block 8, a second roller frame 9, a first bolt 10, a drive shaft 11, a first spring 12, a support block 13, a gasket 14, and a positioning block 15.

[0035] The first roller frame 7 and the second roller frame 9 have the same structure. The extrusion blocks 8 installed on their outer sides are interlocked. When the device is working, the two sets of extrusion blocks 8 cooperate with each other to apply pressure to the incoming raw material and bend and press it into the required wave shape.

[0036] Eight guide rods 2 are vertically fixed on the surface of the support frame 1. These guide rods 2 are distributed in both directions. Their function is to provide precise guidance for the movement of the first roller frame 7 and the second roller frame 9, ensuring the stability of the roller frame movement during the molding process, thereby ensuring the stability of the molding process. At the same time, the first roller frame 7 is installed above the guide rods 2 and the second roller frame 9 is installed below. The two roller frames have the same overall structure. This design ensures the consistency of the upper and lower forces during the molding process, which helps to improve the molding quality.

[0037] The second roller frame 9 is mounted on the outer ring of the drive shaft 11. The drive shaft 11 adopts a hexagonal structure. This special design can effectively prevent relative rotation between the second roller frame 9 and the drive shaft 11, ensuring stable power transmission and making the molding process more reliable.

[0038] The drive shaft 11 is threaded to the left side of the first bolt 10. Four shims 14 are placed between the first bolt 10 and the second roller frame 9. By adjusting the number or position of the shims 14, the axial position of the second roller frame 9 can be flexibly adjusted to meet different processing requirements.

[0039] The right side of the second roller frame 9 is attached to the positioning block 15. The positioning block 15 is slidably connected to the drive shaft 11. The side of the positioning block 15 is fixedly connected to one end of the first spring 12. The other end of the first spring 12 is fixed to the drive shaft 11. The first spring 12 plays a key role in buffering and fine adjustment in the device. It can effectively prevent damage to raw materials or equipment due to excessive pressure and ensure the safety and stability of the processing process.

[0040] The input shaft of the drive shaft 11 is fixedly connected to the first motor 3. The first motor 3 is mounted on the support block 13. The support block 13 is threadedly connected to the lead screw 4. The lead screw 4 is rotatably connected to the support frame 1. By rotating the lead screw 4, the height of the support block 13 can be adjusted, thereby adjusting the height of the first motor 3 and the entire forming mechanism. In this way, the equipment can adapt to the processing requirements of raw materials of different specifications. At the same time, the guide rod 2 is slidably connected to the support block 13, ensuring that the support block 13 can be smoothly raised and lowered under the drive of the lead screw 4, further improving the ease of operation and processing accuracy of the equipment.

[0041] Working principle: When using a wire harness bracket wave bending and pressing forming device, firstly, according to the thickness of the raw material, the height of the bearing block 13 is adjusted by rotating the screw 4, and then the distance between the first roller frame 7 and the second roller frame 9 is adjusted so that the equipment can adapt to the processing requirements of the raw material.

[0042] Then start the second motor 5. The second motor 5 drives the pusher roller 6 to rotate and feed the raw material into the conveying channel. At this time, the second spring 18 installed on the outer ring of the second bolt 16 pushes the fixing plate 17 so that the pusher roller 6 is in close contact with the surface of the raw material, ensuring that the raw material is conveyed forward at a uniform speed and stably.

[0043] When the raw material enters the forming mechanism area, the first motor 3 is started. The first motor 3 drives the drive shaft 11 to rotate, and the drive shaft 11 drives the second roller frame 9 and the extrusion block 8 on it to rotate. They mesh with the extrusion block 8 on the first roller frame 7 and apply pressure to the raw material, bending and pressing the raw material into a wave shape. During this process, the guide rod 2 ensures the stability of the movement of the first roller frame 7 and the second roller frame 9. The first spring 12 plays a role in buffering and fine adjustment to avoid excessive pressure from damaging the raw material and equipment.

[0044] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
