Description

Technical Field

[0001] The present application relates to the technical field of automotive part punching equipment, and particularly relates to an outer water cut inner LIP punching mechanism and a punching method. Background Art

[0002] In the assembly process, many outer water cuts need to assemble end caps. However, the inner Lip interferes with the end cap, so the inner Lip needs to be removed at the corresponding position at the end before assembly. After removing the inner Lip, the end cap can be assembled. The general process plan is to make a variable cross-section on the double pressing to remove the inner Lip at the corresponding position. In the double pressing process, there is a forming die. This forming die is designed according to the cross-section. The normal double pressing is an equal cross-section extrusion. To achieve variable cross-section removal of the inner Lip, during the production process, a program is set in the equipment, and the equipment program controls a cutting mechanism to cut off the inner Lip position in the forming die. When the length reaches our requirements, the equipment program controls the cutting mechanism to return to its original position, and the inner Lip of the product is extruded normally.

[0003] However, the existing variable cross-section process production will cause changes in the pressure of the extrusion molding machine, which is likely to cause defects such as vibration marks and unevenness on the product appearance. To solve the problems of defects such as vibration marks and unevenness on the product appearance, the removal process is optimized, changing the process from double pressing variable cross-section production to double pressing equal cross-section process + 2-step punching process to replace it, achieving a huge improvement in the yield rate. However, the punching of the outer water cut inner Lip requires two processes to complete, and the production efficiency is relatively low. Summary of the Invention

[0004] The present application aims to solve one of the above technical problems in the prior art. To this end, an embodiment of the present application provides an outer water cut inner LIP punching mechanism.

[0005] An embodiment of the present application also provides a punching method.

[0006] According to an embodiment of the first aspect of the present application, there is provided an outer water cut inner LIP punching mechanism, including

[0007] A driving module;

[0008] A die holder;

[0009] A first positioning member capable of resetting, disposed on the die holder. The first positioning member is used for the positioning and guiding of the outer water cut, and the first positioning member can move in a direction perpendicular to the feeding direction of the outer water cut;

[0010] A second positioning member, disposed on the die holder. The second positioning member is used for the end face positioning of the outer water cut;

[0011] A resetable cutter is provided between the first positioning member and the second positioning member on the die base. A first cutting edge and a second cutting edge are provided at the end of the cutter close to the first positioning member. The cutter can move in a direction perpendicular to the feeding direction of the outer water cut.

[0012] During the process of the end of the outer water cut reaching the second positioning member from the cutter, the first cutting edge can cut open the inner Lip of the end of the outer water cut. During the movement of the driving module towards the die base, the first positioning member and the cutter are driven successively, so that the first positioning member drives the to-be-cut position of the separated inner Lip to coincide with the movement path of the second cutting edge. During the movement of the cutter following the driving module, the second cutting edge is driven to cut off the separated inner Lip.

[0013] The above-mentioned outer water cut inner LIP punching mechanism has at least the following beneficial effects: During the feeding process of the outer water cut, through the positioning and guiding of the first positioning member, when the end face of the outer water cut passes through the cutter and reaches the second positioning member, the first cutting edge can divide the inner Lip at the end of the outer water cut. After the end of the outer water cut is positioned in place, that is, after the inner Lip at the end of the outer water cut is separated, the driving module is triggered to act. The driving module drives the first positioning member and the cutter successively, and the first positioning member is used to adjust the to-be-cut position of the divided inner Lip, so that the to-be-cut position of the divided inner Lip moves onto the movement path of the second cutting edge. After the to-be-cut position of the divided inner Lip is adjusted in place, the cutter follows the driving module to move, and the second cutting edge cooperates with the first positioning member to complete the cutting of the divided inner Lip. Compared with the original two-step process of first slitting and then dividing, this application integrates the cutting of the inner Lip into one punching process, and the inner Lip at the corresponding position at the end of the outer water cut can be removed by one loading and unloading of the outer water cut, greatly improving the production efficiency.

[0014] According to the outer water cut inner LIP punching mechanism described in the first aspect embodiment of the present application, the setting direction of the first cutting edge intersects with the setting direction of the second cutting edge.

Detailed Description of the Embodiment

[0047] This part will describe in detail the specific embodiments of the present application. The preferred embodiments of the present application are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present application, but it should not be construed as a limitation on the protection scope of the present application.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0049] In the description of the present application, the meaning of several is one or more, the meaning of multiple is more than two, and the understandings such as greater than, less than, exceeding, etc. do not include the corresponding number, while the understandings such as above, below, within, etc. include the corresponding number. If the first and second are described, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0050] In the description of the present application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present application in combination with the specific content of the technical solution.

[0051] Among them, Figure 1 A cross-sectional schematic diagram of the outer water cut 100 is provided. The width of the inner groove 120 at the opening of the cross-section of the outer water cut 100 product is only about 4 mm. There is an inner Lip 111 inside the Lip part 110 of the outer water cut 100. To avoid defects such as vibration marks and unevenness on the product appearance caused by the production of the compound pressing variable cross-section process, the existing process is improved to an equal cross-section compound pressing process and then the punching process is carried out. The punching process includes two processes of slitting and dividing, that is, first punching a slitting notch at the corresponding position of the inner Lip 111 of the outer water cut 100, and then dividing the inner Lip 111. This process requires two loadings. Although it solves the problems of defects such as vibration marks and unevenness on the product appearance, it reduces the production efficiency.

[0052] Therefore, as Figures 2 to 5 shown, the embodiment of the present application provides an inner Lip punching mechanism for the outer water cut, which optimizes the structural design and improves the punching process of the inner Lip 111 of the outer water cut 100, so that the punching process is improved from the original two processes to one process.

[0053] Specifically, the inner Lip punching mechanism for the outer water cut includes a driving module, a die base 210, a first positioning member 220, a second positioning member 250, and a cutting tool 240.

[0054] Among them, the die base 210 serves as the installation basis for the first positioning member 220, the second positioning member 250, and the cutting tool 240.

[0055] The first positioning member 220 is disposed on the die base 210. The first positioning member 220 is used for positioning and guiding the outer water deflector 100. Under the action of an external force, the first positioning member 220 can move in a direction perpendicular to the feeding direction of the outer water deflector 100. After the external force disappears, the first positioning member 220 can automatically reset.

[0056] The second positioning member 250 is disposed on the die base 210. The second positioning member 250 is used for end face positioning of the outer water deflector 100. The end face of the outer water deflector 100 guided by the first positioning member 220 can accurately reach the second positioning member 250, making the positioning of the outer water deflector 100 more convenient. It should be noted that a sensor is provided at the position where the second positioning member 250 is used to position the end face of the outer water deflector 100.

[0057] The cutter 240 is disposed on the die base 210 and is between the first positioning member 220 and the second positioning member 250. At the end of the cutter 240 close to the first positioning member 220, a first cutting edge 241 and a second cutting edge 242 are provided. The cutter 240 can move in a direction perpendicular to the feeding direction of the outer water deflector 100. The second cutting edge 242 and the first positioning member 220 cooperate to complete the punching operation.

[0058] Among them, during the process that the end of the outer water deflector 100 reaches the second positioning member 250 from the cutter 240, the first cutting edge 241 can cut open the inner Lip 111 at the end of the outer water deflector 100. During the movement of the driving module towards the die base 210, the first positioning member 220 and the cutter 240 are driven successively, so that the first positioning member 220 drives the position to be cut of the separated inner Lip 111 to be adjusted to coincide with the movement path of the second cutting edge 242. During the movement of the cutter 240 following the driving module, the second cutting edge 242 drives to cut off the separated inner Lip 111.

[0059] Specifically, during the feeding process of the outer water deflector 100, through the positioning and guiding of the first positioning member 220, when the end face of the outer water deflector 100 passes through the cutter 240 and reaches the second positioning member 250, the first cutting edge 241 can divide the inner Lip 111 at the end of the outer water deflector 100. After the end of the outer water deflector 100 is positioned in place, that is, after the inner Lip 111 at the end of the outer water deflector 100 is separated, the driving module is triggered to act simultaneously. The driving module drives the first positioning member 220 and the cutter 240 successively. The first positioning member 220 is used to adjust the position to be cut of the divided inner Lip 111, so that the position to be cut of the divided inner Lip 111 moves onto the movement path of the second cutting edge 242. After the position to be cut of the divided inner Lip 111 is adjusted in place, the cutter 240 follows the driving module to move, and the second cutting edge 242 and the first positioning member 220 cooperate to complete the cutting of the divided inner Lip 111.

[0060] Compared with the original two-step process of first slitting and then dividing, that is, it requires two loading and unloading operations, and two different devices are needed during the operation process. In this application, by optimizing the related punching structure, the cutting of the inner Lip111 is integrated into one punching process, and the removal of the inner Lip111 at the corresponding position of the end of the outer water cut 100 can be completed by one loading and unloading of the outer water cut 100, greatly improving the production efficiency.

[0061] In some embodiments, the setting direction of the first cutting edge 241 intersects with the setting direction of the second cutting edge 242. During the cutting process of the inner Lip111, the dividing surface of the inner Lip111 fits against the first cutting edge 241. That is, the Lip part 110 is supported by the first positioning member 220, and the first cutting edge 241 forms a positioning reference to position the inner Lip111, so that during the cutting process, the inner Lip111 is effectively positioned and fixed; during the downward pressing of the second cutting edge 242 following the driving module, the shearing force formed by the second cutting edge 242 and the end of the first positioning member 220 can cut and sever the to-be-cut position of the divided inner Lip111, with high cutting efficiency and guaranteed cutting accuracy.

[0062] In some embodiments, the second positioning member 250 includes a positioning portion 221 for positioning the inner side groove 120 of the opening of the outer water cut 100, and there is a gap between the positioning portion 221 and the first cutting edge 241. Among them, the width of the inner side groove 120 of the opening is generally 4 mm, and the setting width of the positioning portion 221 can be 2 - 2.5 mm, so as to facilitate the loading and positioning of the outer water cut 100.

[0063] Among them, the inner Lip111 during the positioning process faces the positioning portion 221. On the one hand, the first cutting edge 241 and the positioning portion 221 are misaligned, so that the first cutting edge 241 can accurately cut the to-be-divided position of the inner Lip111. On the other hand, the divided inner Lip111 can be effectively separated from the gap. The first positioning member 220 also plays a role in limiting the inner Lip111 during the dividing process, avoiding excessive deviation of the dividing position during the dividing process. After the subsequent cutting of the inner Lip111, during the process of the outer water cut 100 being withdrawn from the first positioning member 220, the first positioning member 220 can limit the remaining inner Lip111 after separation and cutting in the inner side groove 120 of the opening of the outer water cut 100, and there is no need to manually remove the separated and cut inner Lip111 subsequently.

[0064] In some embodiments, such as Figure 7 and Figure 8As shown, the punching mechanism for the inner Lip111 in the outer water cut-off 100 further includes a third positioning member 230. The third positioning member 230 is disposed close to the first cutting edge 241 and fixed to the first positioning member 220. The third positioning member 230 can move following the first positioning member 220. Among them, an adjustment groove is formed between the third positioning member 230 and the positioning portion 221, and the position to be divided of the end portion of the outer water cut-off 100 passing through the adjustment groove can be adjusted to be collinear with the first cutting edge 241.

[0065] The cooperation between the third positioning member 230 and the positioning portion 221 enables the position to be divided of the Lip portion 110 to be adjusted to be collinear with the first cutting edge 241 during movement. The setting of the third positioning member 230 makes the separation of the inner Lip111 smoother and more accurate.

[0066] In some specific embodiments, the third positioning member 230 includes an adjustable wheel 233 that can rotate.

[0067] As Figure 9 shown, the third positioning member 230 includes a mounting block 231 and a fixing member 232. The mounting block 231 is fixed to the first positioning member 220, and the adjustable wheel 233 is rotatably disposed on the mounting block 231 through the fixing member 232. Specifically, the surface of the adjustable wheel 233 and the positioning portion 221 form an adjustment groove. The rotatable adjustable wheel 233 makes the loading and unloading of the outer water cut-off 100 more labor-saving and smooth, and can also prevent the outer water cut-off 100 from getting stuck at the adjustment groove.

[0068] In the embodiment of the present application, the fixing member 232 is a screw, and the adjustable wheel 233 can be a bearing.

[0069] As Figures 10 to 12 shown, the cutter 240 is provided with a limiting groove 244 for guiding and positioning the Lip portion 110 of the outer water cut-off 100 where the inner Lip111 has been divided. The thickness of the limiting groove 244 is slightly larger than the thickness of the Lip portion 110 where the inner Lip111 has been divided, so that the Lip portion 110 where the inner Lip111 has been divided can smoothly pass through the limiting groove 244 to reach the second positioning member 250. The setting of the limiting groove 244 also makes the dividing process more accurate, making the thickness dimensions of each part of the Lip portion 110 where the inner Lip111 has been divided close to the same.

[0070] As Figure 12As shown, a guiding inclined surface 243 is further provided at the end of the cutter 240. The guiding inclined surface 243 extends to be adjacent to the first cutting edge 241, and the guiding inclined surface 243 is located between the first cutting edge 241 and the positioning portion 221. The provision of the guiding inclined surface 243 enables the divided inner Lip 111 to be quickly separated from the Lip portion 110. After the outer water deflector 100 is punched and the blank is discharged, the cut inner Lip 111 will also be pushed away from the inner side groove 120 of the opening of the outer water deflector 100 under the limitation of the first positioning member 220, which is beneficial to the discharge of waste materials.

[0071] Among them, as Figure 13 and Figure 14 shown, in combination with Figure 5 and Figure 6 for understanding, during the process of the first positioning member 220 driving the outer water deflector 100 to be adjusted, the position to be cut of the divided inner Lip 111 is adjusted to fit the first cutting edge 241, and the position to be cut of the divided inner Lip 111 is made to be on the movement path of the second cutting edge 242. When punching, the cutting is made more complete, avoiding the situation of cutting failure caused by the second cutting edge 242 not completely covering the position to be cut of the divided inner Lip 111.

[0072] In some embodiments, as Figure 15 and Figure 16 are schematic diagrams of the first part cutting the inner Lip 111. Under the action of the guiding inclined surface 243, the divided inner Lip 111 can be well separated from the Lip portion 110.

[0073] In some embodiments, as Figures 2 to 8 shown, a guide rail is provided on the die base 210, and a guide groove 223 matching the guide rail is provided on the first positioning member 220. With the cooperation of the guide rail and the guide groove 223, the first positioning member 220 can move in a direction perpendicular to the feeding direction of the outer water deflector 100.

[0074] Furthermore, a first limit block 211 and a second limit block 212 are provided on the die base 210. The first limit block 211 and the second limit block 212 are used to limit the movement range of the first positioning member 220, and at the same time, they also play a role in preventing the first positioning member 220 from disengaging from the guide rail. To enable the first positioning member 220 to automatically reset, a first return spring 270 is provided between the first positioning member 220 and the second limit block 212. Among them, a first positioning hole 224 for positioning the first return spring 270 is provided on the first positioning member 220. Similarly, a second positioning hole for positioning the first return spring 270 is also provided on the second limit block 212. The provision of the positioning holes avoids the situation of the first return spring 270 being offset or twisted, resulting in reset failure.

[0075] In some embodiments, a sliding groove is provided on the die base 210, a slider 260 is arranged in the sliding groove, and the cutting knife 240 is installed on the slider 260. To prevent the slider 260 from disengaging from the sliding groove, a third limiting block 213 is provided at the notch of the sliding groove.

[0076] Furthermore, to enable the slider 260 to automatically reset, a second return spring 280 is arranged in the sliding groove, so that after the external force disappears, under the action of the second return spring 280, the slider 260 can drive the cutting knife 240 to automatically reset.

[0077] It should be noted that when the cutting operation is not performed, a part of the cutting knife 240 can also be used as a guide, so as to accurately guide the end face of the outer water cut 100 to the second positioning member 250.

[0078] In some specific embodiments, such as Figures 2 to 6 shown, the first positioning member 220 is arranged to be movable in the horizontal direction, the cutting knife 240 is arranged to be movable in the vertical direction, the driving module includes a first trigger member 300 and a second trigger member 400, a transmission structure is arranged between the first trigger member 300 and the first positioning member 220, and the transmission structure can convert the vertical movement of the first trigger member 300 into the horizontal movement of the first positioning member 220, and the second trigger member 400 is used to drive the cutting knife 240 to move.

[0079] Specifically, the transmission structure includes a first inclined surface 310 and a second inclined surface 222. The first inclined surface 310 is arranged on the first positioning member 220, and the second inclined surface 222 is arranged on the first trigger member 300. During the movement of the driving module towards the die base 210, the first inclined surface 310 moves to cooperate with the second inclined surface 222, and the first positioning member 220 drives the to-be-cut part of the divided inner Lip111 towards the first cutting edge 241. As the driving module continues to advance, when the first inclined surface 310 and the second inclined surface 222 change from contact to separation, the to-be-cut part of the divided inner Lip111 is adjusted in place, and at this time, the first positioning member 220 maintains this state, so that the to-be-cut part of the divided inner Lip111 maintains contact with the first cutting edge 241 and is on the movement path of the second cutting edge 242; as the driving module continues to advance, the second trigger member 400 drives the slider 260 to move. Since the cutting knife 240 is installed on the slider 260, the cutting knife 240 can drive the second cutting edge 242 to cooperate with the first positioning member 220 to complete the cutting of the to-be-cut part of the divided inner Lip111.

[0080] The structure of the entire inner Lip111 punching mechanism of the outer water cut 100 is simple and the operation is convenient. The cutting process of the inner Lip111 at the end of the outer water cut 100 is optimized, and the original two processes are combined into one process. The cutting and removal of the inner Lip111 can be completed by loading the outer water cut 100 once.

[0081] The embodiment of the present application further provides a punching method based on the punching mechanism of the inner Lip111 of the outer water cut 100 described above, including the following steps:

[0082] Position the inner groove 120 on the opening side of the outer water cut 100 on the first positioning member 220, and push the outer water cut 100 along the extending direction of the first positioning member 220, so that the end of the outer water cut 100 moves towards the second positioning member 250;

[0083] During the process that the end of the outer water cut 100 passes through the first cutting edge 241 of the cutter 240, the inner Lip111 of the outer water cut 100 is separated by the first cutting edge 241. After the end of the outer water cut 100 reaches the second positioning member 250, it is positioned in place and triggers the driving module to act;

[0084] The driving module first triggers the first positioning member 220, so that the first positioning member 220 drives a part of the outer water cut 100 to be adjusted perpendicular to the feeding direction of the outer water cut 100, so that the separated inner Lip111 fits the first cutting edge 241, and the position to be cut of the separated inner Lip111 is adjusted to coincide with the movement path of the second cutting edge 242;

[0085] During the continuous movement of the driving module, it drives the cutter 240 to move, and the second cutting edge 242 cooperates with the first positioning member 220 to complete the cutting of the separated inner Lip111;

[0086] After the driving module resets, the first positioning member 220 and the cutter 240 automatically reset.

[0087] The above has described the embodiments of the present application in detail with reference to the drawings. However, the present application is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present application.
