Description

Technical Field

[0001] The invention belongs to the technical field of tool processing, and in particular relates to a processing device for a profiled blade tool and a processing method for the blade tool. Background Art

[0002] As an important component of the electronics industry, FPC (Flexible Printed Circuit, FPC for short) requires a reinforcing plate due to factors such as structure and strength. In the prior art, the FPC reinforcing plate outer shape (generally a hollow closed ring composed of line segments and fillets) often needs to be attached with a layer of glue that shrinks inward and has dimensional tolerance requirements due to the needs of the process. According to the production process, punching and blanking processes are used. In conventional production, a punch tool is generally used to punch out the core waste, and then a punch tool is used to punch out the outer shape blanking. However, since the product is a hollow closed ring, the product is easy to fall under the die and overlap with the waste when punching the outer shape in the last step, which not only affects the product quality, but also makes it inconvenient to remove the product. On the other hand, due to the shrinkage characteristics of special glue materials, the R angle size and accuracy of the product are easily affected when a punch tool is used for blanking.

[0003] In order to overcome the above problems existing in the process of blanking the outer shape using punch cutters, as an improvement, a blade-type cutter adapted to the shape of the product can be used to replace the existing punch cutter for blanking. However, if a blade-type cutter is used for blanking in the process of blanking the outer shape, a special mold needs to be designed to process the blade-type cutter, which greatly increases the production cost and has poor economic efficiency.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Reference Figure 1An embodiment of the present invention provides a processing device for a forming blade type tool, including a length adjustment device and a rounded corner forming device, wherein the length adjustment device includes a guide rail 11, a displacement sensor (not shown in the figure), a data display 13, and a positioning top block 14 for fixing the tool material, wherein the positioning top block 14 is slidably connected to the guide rail 11, the displacement sensor is mounted on the positioning top block 14 and is electrically connected to the data display 13 (for example, the electrical connection between the displacement sensor and the data display 13 is achieved by means of a wire or the like); the rounded corner forming device includes a seat body 21, a driving mechanism 22 mounted on the seat body 21, and a rounded corner processing punch 23 detachably mounted on the seat body 21, wherein the rounded corner processing punch 23 is transmission-connected to the driving mechanism 22 and is arranged corresponding to the positioning top block 14.

[0035] In this embodiment, the size of the rounded corner processing punch 23 can be replaced according to the size of the rounded corner to be processed. In this way, by replacing different rounded corner processing punches 23, rounded corners of different sizes can be processed.

[0036] In this embodiment, the operating principle of the processing device for the profiled blade tool is as follows:

[0037] Before processing, the circumference length L of the blade tool (i.e., the straight length after the hollow closed ring blade tool is unfolded) is determined according to the drawing, and then one end of the tool material with a length of L is fixed on the positioning top block 14, and the other end is placed on the processing position of the fillet processing punch 23, wherein L = total length of the line segment + total length of the arc; during processing, the processing size and positioning value of the first fillet (i.e., the fillet in the blade tool that is farthest from the positioning top block 14) can be determined according to the drawing, and the fillet processing punch 23 corresponding to the fillet is replaced, and then the position of the positioning top block 14 on the guide rail 11 is adjusted (i.e., the positioning top block 14 is moved in the direction close to the fillet processing punch 23). In the process of moving the positioning top block 14, the displacement sensor will detect in real time The displacement of the positioning top block 14 is measured and the detected displacement data is transmitted to the data display 13 for display; when the value on the data display 13 is equal to the positioning value determined in advance according to the drawing, it indicates that the processing position of the first fillet has been determined. At this time, the fillet processing punch 23 is driven by the driving mechanism 22 to extrude the tool material, thereby processing the first fillet on the tool material. In this way, the same operation as the processing process of the first fillet is repeated, and other fillets are processed. When the last fillet is processed, the tool material is removed from the positioning top block 14, and then installed in the pre-wired cutting edge groove on the mold by bonding or interference fit (the edge groove is the final use position of the blade-type tool), thereby completing the processing, forming and installation of the blade-type tool.

[0038] In this embodiment, the processing device for forming edge-type tools determines the processing position of each rounded corner in the edge-type tool through a length adjustment device, and forms the rounded corner structure at different positions in the edge-type tool by replacing the rounded corner processing punch 23 corresponding to the shape of each rounded corner. In this way, by adopting a processing method in which the rounded corner processing position is determined by the length adjustment device while the rounded corner structure is formed by the rounded corner forming device, rapid processing of the edge-type tool is achieved.

[0041] Further, refer to Figure 1 and Figure 3 In an exemplary embodiment, the driving mechanism 22 includes a handle 221 and a movable rod 222, and the base body 21 has an active space 211, wherein the handle 221 is rotatably connected to the base body 21, the movable rod 222 is located in the active space 211, and the first end of the movable rod 222 is hinged to the handle 221, and the second end is detachably connected to the first rounded corner molding piece 231 or the second rounded corner molding piece 232.

[0042] In this embodiment, based on the above structural design, when processing the rounded corners, the first rounded corner forming piece 231 and the second rounded corner forming piece 232 can be matched by simply rotating the handle 221, thereby realizing the processing of the rounded corners, which is very convenient to operate.

[0043] Further, refer to Figure 1 and Figure 3In an exemplary embodiment, the driving mechanism 22 further includes a connecting rod 223 , which is located in the activity space 211 , and one end of the connecting rod 223 is fixed to the handle 221 , and the other end is hinged to the first end of the activity rod 222 .

[0044] In this embodiment, based on the above structural design, the hinge connection between the handle 221 and the movable rod 222 is achieved in a simple and reliable manner.

[0045] Further, refer to Figure 1 and Figure 2 In an exemplary embodiment, the aforementioned processing device for forming edge type cutting tools further comprises a mounting block 24 mounted on the seat body 21, wherein one end of the first rounded corner forming member 231 has a first rounded corner forming portion 2311, and the other end has a first mounting portion 2312; one end of the second rounded corner forming member 232 has a second rounded corner forming portion 2321 matched with the first rounded corner forming portion 2311, and the other end has a second mounting portion 2322; the mounting block 24 has a first mounting portion 2312 and a second mounting portion 2322. The movable rod 222 has a first mounting slot (not shown in the figure) adapted to the first mounting portion 2312 and the second mounting portion 2322, and the second end of the movable rod 222 has a second mounting slot (not shown in the figure) adapted to the first mounting portion 2312 and the second mounting portion 2322.

[0047] Further, refer to Figure 1 In an exemplary embodiment, the length adjustment device further includes a slider 15 slidably engaged with the guide rail 11 , wherein the positioning top block 14 is mounted on the slider 15 .

[0048] In this embodiment, based on the above structural design, the positioning top block 14 can be moved along the guide rail 11 to adjust the processing position of each fillet. In some embodiments, in order to better realize the positioning of the fillet processing position, a stopper (not shown in the figure) can be added to the slider 15. When the processing position of a fillet is adjusted (that is, when the value on the data display 13 is equal to the positioning value determined in advance according to the drawing), the slider 15 and the positioning top block 14 are fixed to the guide rail 11 as a whole through the stopper, so as to better realize the positioning of the fillet processing position and avoid the positioning top block 14 from moving during the fillet processing and affecting the accuracy of the processing position.

[0053] In this embodiment, by installing various components on the base plate 3, the overall transportation can be facilitated.

[0054] Correspondingly, refer to Figures 1 to 7 The embodiment of the present invention further provides a method for processing a blade-shaped tool, which is applied to a processing device for a formed blade-shaped tool in any of the above embodiments, and comprises the following steps:

[0055] Step S1, calculating the perimeter length of the blade-shaped tool according to the drawing of the blade-shaped tool;

[0056] Step S2, taking a tool material whose size length is the perimeter length, and fixing one end of the tool material on the positioning top block 14;

[0057] Step S3, determining the processing dimensions of each fillet in the blade-shaped tool according to the drawing, and replacing the fillet processing punches 23 that match each fillet one by one;

[0058] Step S4, calculate the positioning value of each fillet according to the drawing, and adjust the position of the positioning top block 14 on the guide rail 11 respectively. When the value on the data display 13 is equal to the positioning value of the corresponding fillet, use the corresponding fillet processing punch 23 to process each fillet respectively.

[0059] In the above step S1, the size of each line segment part of the blade-shaped tool and the radius of each rounded corner part can be obtained according to the drawing. For ease of understanding, the following example is used to process the blade-shaped tool. Figures 5 to 7 Take the blade tool shown as an example for explanation, assuming that a point on a line segment in the blade tool is used as the expansion port 41 for expanding the blade tool, and the expansion port 41 is used as the starting point. It is assumed that the lengths of the line segments in the blade tool are A, B, C, D, E, F, and G, respectively, and there are a total of seven fillets a, b, c, d, e, f, and g, and the arc lengths of half of each fillet are C1, C2, C3, C4, C5, C6, and C7, respectively. The straight line length (i.e., the circumference length) of the blade tool after expansion is L. Considering that the tool material will have a certain deformation when the fillet is bent, the length of each arc needs to be compensated after expansion. A certain coefficient (i.e. compensation coefficient), and the compensation coefficient is an empirical value, which varies according to different fillet radii and corresponding central angles. Assuming that the compensation coefficients of fillets a, b, c, d, e, f, and g correspond to T1, T2, T3, T4, T5, T6, and T7 respectively, then L = total length of line segments + total length of arcs = A+B+C+D+E+F+G+2×(C1×T1+C2×T2+C3×T3+C4×T4+C5×T5+C6×T6+C7×T7), among which the length of each line segment and the arc length of each fillet can be determined on the drawing through auxiliary software such as CAD.

[0060] In the above step S2, in some embodiments, when measuring the tool material with a length of L, one end of the tool material can be fixed in the positioning slot 141 of the positioning top block 14, and then the positioning top block is moved along the guide rail. When the value of the data display 13 is L, the tool material with a length of L is cut using the existing cutting tool; of course, in some other embodiments, the tool material with a length of L can also be cut at other stations, and then the tool material can be transferred to the current processing station.

[0061] In the above step S3, it should be noted that regarding the rounded corners in the blade-type tool, since the rounded corners are not necessarily the standard 1 / 4 rounded corners or 1 / 2 rounded corners in actual design, and the corresponding center angle may be any angle, the same rounded corner may correspond to multiple sets of rounded corner processing punches 23 in the actual process.

[0062] In the above step S4, for the convenience of understanding, assuming that the fillet a needs to be processed at present, when the value on the data display 13 is A+C1×T1, the processing position of the surface fillet a has been adjusted. At this time, the fillet processing punch 23 matching the fillet a can be replaced to process the fillet a. Similarly, the processing of the remaining fillets can be continued in the same operation as the processing process of fillet a. In this step, it should be noted that since there are multiple sets of fillet processing punches 23 corresponding to the same fillet in the actual process, therefore, in order to ensure the processing accuracy, during the processing process, the corresponding center angle can be measured first by auxiliary software such as CAD, and then a fillet processing punch 23 with an angle slightly smaller than the actual angle can be selected for processing. After all the fillets in the blade-type tool are processed, they are installed in the pre-wired cutting groove on the mold by bonding or interference fit for fine adjustment, thereby completing the processing and installation of the blade-type tool.

[0063] In this embodiment, based on the above steps, the processing method of the blade-shaped tool determines the processing position of each fillet in the blade-shaped tool through the length adjustment device, and forms the fillet structure at different positions in the blade-shaped tool by replacing the fillet processing punch 23 that matches the shape of each fillet. In this way, by adopting a processing method that determines the fillet processing position through the length adjustment device while forming the fillet structure through the fillet forming device, the rapid processing of the blade-shaped tool is achieved, and compared with the traditional processing method of forming the blade-shaped tool with a special mold, the processing cost of the tool is greatly reduced. It should be noted here that for other contents of the processing method of the blade-shaped tool of this embodiment, please refer to the above description of the processing device for forming the blade-shaped tool, which will not be repeated here.

[0064] It should be noted that in some other embodiments, the blade-type tool can be divided into multiple sections for processing. After processing, each section structure is installed in the blade groove on the mold by bonding or interference fit and connected together to form a blade-type tool. The processing process of each section structure can refer to the above description of the processing method of the blade-type tool, which will not be repeated here.

[0065] It should be noted that other contents of the processing device for forming blade type cutting tools disclosed in the present invention can be found in the prior art and will not be described in detail here.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
