Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness head forging device. Background Art

[0002] Automotive wiring harness heads, also known as automotive wiring harness connectors or plugs, are crucial components in automotive circuit systems. They bridge the gap between two or more isolated electronic circuits, enabling the flow of current and the functions of various electronic components. During the wiring harness production process, the cylindrical metal wires within the harness often need to be flattened to improve the stability of the connection. However, due to the high ductility of metal wire, forging the cylindrical wires results in a flat, irregular shape, which is unsuitable for use and requires trimming. Utility Model Content

[0003] The main purpose of the utility model is to provide a forging device for an automobile wiring harness head, which is used to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A forging device for an automotive wiring harness head includes a base with a housing fixed to its upper end. A horizontal wiring harness inlet is provided on one side of the housing, and a forging chamber is connected to the right side of the wiring harness inlet. A forging assembly is provided on the right side of the forging chamber, and a trimming assembly is provided on the left side of the forging chamber. The forging assembly includes a hydraulic cylinder, a pressure plate, and a forging table. A vertical hydraulic cylinder is provided at the top of the housing. The telescopic rod of the hydraulic cylinder moves through the housing and is fixedly connected to the pressure plate. A forging table that cooperates with the pressure plate is provided under the pressure plate. The trimming assembly includes a servo motor, a forward and reverse threaded rod, an upper slider, and a lower slider. A vertical servo motor is provided at the top of the housing. The power output shaft of the servo motor rotates and penetrates into the interior of the housing and is connected to the forward and reverse threaded rod. The forward and reverse threaded sections of the forward and reverse threaded rod are threadedly engaged with the upper slider and the lower slider, respectively. An upper groove is provided on the lower side of the upper slider, and a lower groove is provided on the upper side of the lower slider. The upper groove and the lower groove are snapped together to form a flat rectangular hole.

[0006] Furthermore, a dovetail groove is provided on one side of the forging chamber, and a protrusion is provided on one side of the upper and lower sliders to match the dovetail groove. The protrusion slides up and down along the dovetail groove, which can make the upper and lower sliders move more smoothly.

[0007] Furthermore, bearings are provided at the lower ends of the forward and reverse screw rods, and the bearings are mounted on the base.

[0008] Furthermore, the harness inlet is a circular hole, and the upper and lower sliders are symmetrically arranged along the central axis of the harness inlet. This arrangement ensures that when the upper and lower grooves are coupled to form a flat rectangular hole under the drive of the servo motor, the rectangular hole is at the same height as the harness inlet.

[0009] This utility model also includes other components that enable the normal operation of the automotive wiring harness head forging device. These devices or components all utilize conventional technologies in the art. Furthermore, devices and components not otherwise specified in this utility model, such as the servo motors described herein, all utilize conventional technologies in the art. During implementation, appropriate device or component models can be selected based on the specific work scenario.

[0010] The working principle of this utility model is as follows: a wire harness segment is inserted into a forging chamber through the harness inlet. After the forging assembly forges the wire of the wire harness segment, a servo motor drives the forward and reverse screw rods to rotate, causing the upper and lower sliders to move toward each other. The upper and lower grooves encircle the wire from both sides and interlock to form a flat rectangular hole. When the wire harness segment is removed from the forging chamber, the rectangular hole squeezes and trims the end of the wire to meet usage requirements.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the metal wire after forging can be trimmed to ensure the stability of the wire harness connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0016] Example:

[0017] like Figures 1-2As shown, a forging device for a wiring harness head of an automobile comprises a base 1, with a casing 2 fixed at the upper end of the base 1. A horizontal wiring harness inlet 21 is provided on one side of the casing 2, and a forging chamber 22 is connected to the right side of the wiring harness inlet 21. A forging assembly is provided on the right side of the forging chamber 22, and a trimming assembly is provided on the left side of the forging chamber 22. The forging assembly comprises a hydraulic cylinder 4, a pressure plate 5 and a forging table 6. A vertical hydraulic cylinder 4 is provided at the top of the casing 2. The telescopic rod of the hydraulic cylinder 4 is fixedly connected to the pressure plate 5 after being movable through the casing 2. A forging table 6 cooperating with the pressure plate 5 is provided under the pressure plate 5. The trimming assembly comprises a servo motor 7, a forward and reverse threaded rod 8, an upper slider 9 and a lower slider 10. A vertical servo motor 7 is provided at the top of the casing 2. The power output shaft of the servo motor 7 rotates and penetrates into the interior of the casing 2 and is connected to the forward and reverse threaded rod 8. The forward threaded section and the reverse threaded section of the forward and reverse threaded rod 8 are respectively threadedly matched with the upper slider 9 and the lower slider 10. An upper groove 12 is formed on the lower side of the upper slider 9 , and a lower groove 13 is formed on the upper side of the lower slider 10 . The upper groove 12 and the lower groove 13 are buckled together to form a flat rectangular hole.

[0018] Furthermore, bearings 11 are installed at the lower ends of the forward and reverse screws 8 and are mounted on the base 1. A dovetail groove 23 is defined on one side of the forging chamber 22, and protrusions are provided on the upper and lower sliders 9 and 10 to mate with the dovetail groove 23. The wiring harness inlet 21 is a circular hole, with the upper and lower sliders 9 and 10 symmetrically positioned vertically along the central axis of the wiring harness inlet 21.

[0019] The working principle of the automotive wiring harness head forging device of the present invention is as follows: a wiring harness segment 3 is inserted into a forging chamber 22 through a wiring harness inlet 21. After the forging assembly forges the metal wire 31 of the wiring harness segment 3, a servo motor 7 drives the forward and reverse screw rods 8 to rotate, causing the upper slider 9 and the lower slider 10 to move toward each other. The upper groove 12 and the lower groove 13 encircle the metal wire 31 from the upper and lower sides and interlock with each other to form a flat rectangular hole. During the process of withdrawing the wiring harness segment 3 from the forging chamber 22, the rectangular hole squeezes and trims the end of the metal wire 31 to meet the needs of use.
