[0002] Shell chamfering refers to the chamfering of the edges or corners of the product to improve the appearance quality, increase comfort, reduce injuries, and improve the durability of the product. This processing is usually applied to the shells, shell components or mechanical parts of various products.

[0003] For workpieces such as notebook shells, chamfers need to be formed on the edges and corners of the workpieces, and such workpieces are usually formed by stamping. There is no excess material on the edges and corners for milling chamfers, so most of them use the extrusion chamfering process.

[0004] The extrusion chamfering process selects a specific extrusion head according to the shape and size of the required chamfer. The edge or corner of the workpiece is chamfered by the extrusion of the extrusion head. Its advantages are short production cycle, high processing accuracy, and the chamfering process can be completed in one extrusion process, avoiding the complicated operation of multiple processes. It is suitable for mass production and can also achieve more complex chamfer shapes, improving the appearance quality and functionality of the product.

[0005] In the prior art, the extrusion chamfering of the notebook shell is a relatively complete processing technology, but there are still problems such as the cumbersome replacement of the extrusion head and the inability to adapt to chamfering processing of various shapes through a set of extrusion equipment.

[0006] Therefore, a new design is needed that can quickly replace the extrusion head according to the actual chamfer depth and chamfer shape. Utility Model Content

[0010] The extrusion clamp is fixed to the extrusion head via a fixing pin.

[0011] The part of the extrusion clamp where the extrusion head is arranged is provided with a pin hole which vertically penetrates the extrusion clamp, and the extrusion head is provided with a pin hole which matches the extrusion clamp.

[0012] The extrusion fixture includes two parts, namely an extrusion head part for chamfering the outer frame in all directions and a pressure plate part for pushing the extrusion head part to move. The extrusion head part and the pressure plate part are provided with mutually matching inclined surfaces. When the pressure plate part moves downward, it can drive the extrusion head part to move toward the chamfered outer frame.

[0013] The inner shape formed by winding the chamfered outer frame is a square, and the extrusion head part is provided with four.

[0014] The chamfered outer frame is a detachable structure and is movably connected to the base.

[0022] The utility model is further described below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, the utility model mainly includes a base 1, an extrusion fixture 2 and a chamfered outer frame 5.

[0024] The base 1 is the bottom layer of the utility model, and the chamfered outer frame 5 is arranged above the base 1, and a plurality of chamfered outer frames 5 surround the extrusion chamfering working area according to the actual shape of the workpiece, and the inside of the chamfered outer frame 5 is the part for extrusion chamfering, and its actual size is slightly larger than the workpiece to be processed. In this embodiment, the workpiece to be processed is the shell of a laptop computer, so four chamfered outer frames 5 are arranged and surround the square working area.

[0025] On the side where the chamfered outer frame 5 contacts the workpiece, its shape is the shape that needs to be chamfered, and the chamfered outer frame 5 is fixed to the base 1 by vertically arranged fixing pins. The vertically arranged fixing pins are convenient for disassembly and replacement on the one hand, and can also provide sufficient horizontal resistance for the chamfered outer frame 5 on the other hand.

[0026] The extrusion clamp 2 is also arranged above the base 1, and the overall size of the extrusion clamp 2 is slightly smaller than the working area formed by the chamfered outer frame 5. When performing extrusion chamfering, the extrusion clamp 2 is installed inside the working area surrounded by the chamfered outer frame 5, and extrusion is performed from the center part toward the direction of the chamfered outer frame 5.

[0027] The extrusion fixture 2 mainly includes an extrusion head part and a pressing plate 4. The specific structure is as follows Figure 1 The main body of the extrusion head part is a fixture part for loading the extrusion head 3 and a detachable and replaceable extrusion head 3. The extrusion head 3 is arranged at the bottom of the fixture part close to the chamfered outer frame 5. At the same time, a latch hole 6 for installing a latch is vertically arranged between the extrusion head 3 and the fixture part above it. The latch hole 6 runs through the entire fixture part and the extrusion head 3, and their positions correspond to each other. The fixture part of the extrusion head 3 is combined and fixed by the latch, and it is also very convenient to disassemble and replace the extrusion head 3.

[0028] The pressing plate 4 is arranged at a position where the extrusion head part is located on the opposite side of the chamfered outer frame 5. In this embodiment, the extrusion head part moves from the center of the square working area to the four sides, so the pressing plate 4 is arranged at the center of the working area, and the contact parts of the pressing plate 4 and each extrusion head part are all arranged as inclined structures, and the extrusion head part is also arranged as mutually matching inclined structures. When the pressing plate 4 is pressed down, the extrusion head part will move toward the chamfered outer frame 5 under the action of the inclined surface, realizing the function of extrusion chamfering.

[0029] In actual use, the models of the extrusion head 3 and the chamfered outer frame 5 are determined according to the chamfered shape and structure required, the chamfered outer frame 5 is installed on the base 1, and the extrusion head 3 is fixed to the extrusion head part of the extrusion fixture 2.

[0030] At this time, the workpiece to be processed is placed in the working area surrounded by the chamfered outer frame 5 on the base 1. The workpiece to be processed is the notebook shell whose edge needs to be extruded and chamfered. After the workpiece is placed, it is placed in the extrusion fixture 2. At this time, the pressing plate 4 is not completely pressed down, so the overall size of the extrusion fixture 2 is smaller than the notebook shell, and the extrusion head part can be easily placed into the middle part of the notebook shell and aligned with the chamfered outer frame 5 corresponding to the extrusion head 3.

[0031] After the installation is completed, the pressing plate 4 is pressed down. At this time, under the action of the inclined surface of the pressing plate 4 and the extrusion head, the extrusion head 3 presses the edge of the workpiece and moves toward the chamfered outer frame 5 for extrusion. When the pressing plate 4 is pressed down to the preset position, the pressing plate 4 is lifted up, the extrusion fixture 2 is taken out, and the extrusion chamfering process is completed.
