Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding and cutting equipment, in particular to an automatic ultrasonic punching device for automobile accessories. Background Art

[0002] In the automotive manufacturing industry, the same model often comes in different trim levels. The most obvious difference lies in the presence or number of front and rear radars, or speakers on the A and B pillars. However, these components share the same physical structure; only the number and presence vary. This means that only the number of components varies, and these components are typically molded using a single set of injection molds, given the high cost of plastic molds. Therefore, when manufacturing a high-end model, it's often sufficient to simply drill holes in the plastic parts of the low-end model to add accessories like radars or speakers. Early on, these holes were mostly drilled, but drilling resulted in poor positioning and easily scratched the A-side. Later, hydraulic punching became the common method. While this process is reliable, the hydraulic system is difficult to maintain, produces significant noise, and has high manufacturing and maintenance costs, impacting the production efficiency of these auto parts. For example, the rear door guards of the high-end and low-end models of a given car have holes for radars, while the low-end models have no holes and lack radars.

[0003] Hydraulic punching is used for punching holes in injection molded plastics, which offers high precision. However, it is inefficient, costly, and noisy. Ultrasonic punching not only ensures precision and reduces noise, but also significantly reduces labor costs and improves efficiency.

[0004] Traditional manual drilling and hydraulic punching are costly and noisy, presenting deficiencies in the injection molding process and lacking a competitive advantage in the increasingly intelligent manufacturing landscape. Utility Model Content

The utility model utilizes the punching and lifting cylinder as punching power, automatically punching downward, ensuring rapid punching of plastic part holes and easy maintenance.

[0008] In addition, the utility model adopts a pressing cylinder to press the automobile parts, so as to ensure that the automobile parts do not move during punching and the punching position is accurate.

[0009] The present invention can also be further improved as follows.

[0010] The profiling pressing block is located below the ultrasonic welding device, and a clearance hole is provided at a position of the profiling pressing block corresponding to the ultrasonic welding device.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1, as Figures 1 to 5 As shown, an automatic ultrasonic punching device for automobile accessories includes a frame 1, a base 3, a lower mold 8, a punching and lifting cylinder 2, a lifting slide 5, an ultrasonic welding device 6 and a pressing cylinder 7. The base 3 is located below the frame 1, and the lifting slide 5 is arranged on the frame 1 for sliding up and down. The punching and lifting cylinder 2 is arranged upside down on the frame 1 and drives the lifting slide 5 to slide up and down. The ultrasonic welding device 6 is arranged on the lifting slide 5 and is located above the lower mold 8. The pressing cylinder 7 is arranged upside down on the frame 1 and is located above the lower mold 8. A contoured pressing block 71 is provided on the cylinder rod of the pressing cylinder 7.

[0026] As a more specific technical solution of the utility model.

[0027] The contoured pressing block 71 is located below the ultrasonic welding device 6 , and a clearance hole 70 is provided at a position of the contoured pressing block 71 corresponding to the ultrasonic welding device 6 .

[0028] A guide post 81 is provided at the bottom of the lifting slide 5 , and a guide sleeve 82 is provided on the base 3 at a position corresponding to the guide post 81 .

[0029] A lifting guide rail 11 is provided at the bottom of the frame 1 , and the lifting slide 5 is slidably arranged on the lifting guide rail 11 .

[0030] The ultrasonic welding device 6 includes a transducer 61 , a primary welding rod 62 and a secondary welding rod 63 which are sequentially connected from top to bottom.

[0031] The ultrasonic welding device 6 of the present invention is prior art.

[0032] The working principle of this utility model is:

[0033] The worker places the auto parts on the lower mold 8, and then the worker starts the utility model. The pressing cylinder 7 first drives the profiling block 71 to descend, and the profiling block 71 presses the auto parts onto the lower mold 8. Then the punching and lifting cylinder 2 drives the lifting slide 5 to slide downward, and the lifting guide rail 11, guide column 81 and guide sleeve 82 guide the lifting slide 5 to descend. The ultrasonic welding device 6 descends, and the secondary welding rod passes downward through the profiling block 71. The secondary welding rod rests on the plastic auto parts, and the transducer 61 starts working. The transducer 61 generates high-frequency vibration, and then the high-frequency vibration of the transducer 61 is transmitted to the primary welding rod 62 and the secondary welding rod 63 in turn. The lower end of the secondary welding rod 63 melts the plastic auto parts and punches downward, and the auto parts are punched out of the opening.
