Description

Technical Field

[0001] This utility model belongs to the field of plastic parts processing technology, and more specifically, it relates to a plastic punching device. Background Technology

[0002] The production and manufacturing of automotive interiors involves the processing of plastic parts. Some of the larger plastic parts are formed by assembling multiple plastic components. Before assembly, the plastic parts are punched. However, currently, the punching of plastic parts is done manually by placing them in a special punching equipment area. For some plastic parts with low precision requirements, the punching efficiency is insufficient and the batch processing efficiency is low.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a plastic punching device in order to achieve a more practical purpose. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a plastic punching device to solve the issues of insufficient punching efficiency and low batch processing efficiency of workshop punching devices for processing plastic parts with low precision requirements.

[0005] The purpose and effect of this utility model's plastic punching device are achieved through the following specific technical means:

[0006] A plastic punching device includes a mounting base disposed on one side of a plastic part conveyor line. Multiple support arms are provided on the mounting base near the conveyor line, forming punching slots between adjacent support arms. A side frame is provided on the mounting base, and a punching device is mounted on the top of the side frame. The drill bit at the bottom of the punching device corresponds to the punching slot. Rotary seats are provided on both sides of the mounting base, and a positioning element is rotatably disposed between the two rotary seats. A notch is provided between the side frame and the mounting base, and a cylinder is rotatably connected within the notch. The output shaft of the cylinder drives the positioning element to swing, causing the positioning element to grip the plastic part on the conveyor line.

[0007] Furthermore, the positioning component includes a U-shaped frame, with latches formed at both ends of the opening of the U-shaped frame, a horizontal shaft passing through the two rotating seats, the horizontal shaft passing through both sides of the U-shaped frame, and the output end of the cylinder being slidably connected to the U-shaped frame.

[0008] Furthermore, the horizontal shaft is fitted with a rotating sleeve, which is connected to the rear end of the U-shaped frame via a connecting shaft. A slider is slidably fitted on the connecting shaft, and the output end of the cylinder is connected to the slider.

[0009] Furthermore, the bottom of the U-shaped frame is provided with a paddle corresponding to the buckle claw, and the gap formed between the paddle and the buckle claw is greater than the thickness of the folded edge of the plastic part.

[0010] Furthermore, hinge shafts are fixedly provided on both sides of the cylinder, and the hinge shafts are movably inserted into the two side walls corresponding to the notch of the mounting seat.

[0011] Furthermore, the drilling device is a drilling machine or a hydraulic punching machine, and the number of them corresponds to the number of drilling slots.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing the punching device on the plastic parts conveyor line, the cylinder pushes the positioning part to flip down, which can position the plastic part below the punching machine. After punching is completed, the cylinder retracts, causing the positioning part to restrict one end of the plastic part to flip up, releasing the positioning of the plastic part. Then the plastic part continues to follow the conveyor line to the next process. The integrated punching design improves the efficiency of batch punching of plastic parts.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a plastic punching device, including a mounting base 1 disposed on one side of a plastic part conveying line 7. The mounting base 1 is installed next to the support of the conveying line 7. Multiple support arms 101 are disposed on the side of the mounting base 1 near the conveying line 7. A punching groove 102 is formed between adjacent support arms 101. In this embodiment, three support arms 101 are disposed and two punching grooves 102 are disposed, which is suitable for plastic parts with double holes.

[0026] The mounting base 1 is provided with a side frame 2, and a punching device is provided on the top of the side frame 2. The drill bit 301 at the bottom of the punching device corresponds to the punching groove 102. In this embodiment, the punching device used is a drilling machine. The drill bit 301 rotates and moves down to punch the plastic part. In other embodiments, a punching machine can be used to directly squeeze the plastic part downward to punch it, which can achieve the same effect.

[0027] Rotary seats 4 are provided on both sides of the mounting base 1. A positioning component 6 is rotatably arranged between the two rotating seats 4. The positioning component 6 includes a U-shaped frame 601. The two ends of the opening of the U-shaped frame 601 form a latch 605. A horizontal shaft 5 is passed through the two rotating seats 4 and passes through both sides of the U-shaped frame 601. A notch is provided between the side frame 2 and the mounting base 1. A cylinder 8 is rotatably connected in the notch. The output end of the cylinder 8 is slidably connected to the U-shaped frame 601. The output shaft of the cylinder 8 drives the positioning component 6 to swing, so that the positioning component 6 grabs the plastic parts on the conveyor line 7.

[0028] When the plastic part passes the mounting base 1, the cylinder 8 pushes the rear end of the U-shaped frame 601, so that the latch 605 at the front end of the U-shaped frame 601 latches the plastic part inward between the rotating base 4 and the latch 605, completing the positioning. At this time, the punching device can punch a hole in the plastic part. After the punching is completed, the cylinder 8 retracts, the latch 605 swings up to release the restriction on the plastic part, and the plastic part continues to the next process along the conveyor line 7.

[0029] During the upward swing of the claw 605, the bottom of the U-shaped frame 601 is equipped with a lever 606 corresponding to the claw 605. The gap formed between the lever 606 and the claw 605 is greater than the thickness of the folded edge of the plastic part. The upward swing lever 606 can push the plastic part back to its normal position on the conveyor line 7.

[0030] Because hinge shafts 9 are fixedly installed on both sides of cylinder 8, and hinge shafts 9 are movably inserted into the side walls corresponding to the notch of mounting base 1, cylinder 8 will not get stuck during extension and retraction, and the linkage between components is smoother; specifically, a rotating sleeve 602 is sleeved on the transverse shaft 5, and the rotating sleeve 602 is connected to the rear end of U-shaped frame 601 through a connecting shaft 603. A slider 604 is slidably sleeved on the connecting shaft 603, and the output end of cylinder 8 is connected to slider 604. During the extension and retraction of cylinder 8, slider 604 slides on connecting shaft 603, which can realize the extension and retraction of cylinder 8 and the swing of U-shaped frame 601 in coordination without interference in the direction of movement.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
