Description

Technical Field

[0001] The present application relates to the technical field of automobile parts production, and in particular to a guide groove dysposition notch punching structure and a punching device. Background Art

[0002] The guide groove is a semi-finished product obtained by rolling and bending, and then punched to obtain the finished product. The finished guide groove is mainly welded to the A-pillar, B-pillar, and C-pillar, and is used to protect and guide the glass lifting after installation. Punching the guide groove requires processing a first notch and a second notch of different shapes at the same end. The first notch and the second notch are distributed on both sides of the same end. However, due to the unique shape characteristics of the guide groove and the immature design experience before, in order to avoid deformation of the guide groove caused by punching, the previous punching process is to punch the two notches separately. This requires many steps. In addition to the punching operation, the guide groove requires three punching steps to complete production. Therefore, a large number of production personnel and punching equipment are required, resulting in low production efficiency, which is also the reason for the high development and production costs.

DETAILED DESCRIPTION

[0032] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0035] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0036] Reference Figure 1 and Figure 2The structure of the guide groove 100 is relatively irregular, and is responsible for the outer and inner sides. Among them, the retaining edge 110 on one side of the guide groove 100 is inclined toward the other side, and the other side of the guide groove 100 has a recess 120 protruding toward the other side. Therefore, when performing the punching of the first notch and the second notch, it is necessary to consider supporting the inner side of the guide groove 100. In the past, due to insufficient R&D capabilities, it was impossible to perform the punching of the first notch and the second notch at one time without causing deformation of the guide groove 100. Therefore, the punching of the notch was set into two steps and performed separately. This not only takes into account the punching but also avoids deformation. However, as the requirements for production efficiency continue to increase, the production of multiple processes cannot keep up with the pace on the one hand, and on the other hand, it will also cause waste of manpower and material resources.

[0037] In order to solve the efficiency and cost problems, the present application provides a guide groove 100 eccentric notch punching structure capable of simultaneously punching two notches at the end of the guide groove 100. Specifically, Figure 3 and Figure 4 As shown, the eccentric notch punching structure of the guide groove 100 includes a first fixture, a second fixture 220 and a punching piece 310 .

[0038] Among them, such as Figure 5 and Figure 6 As shown, the first fixture 210 includes a first contoured surface 211 . The first contoured surface 211 is used to support the outer side surface of the guide groove 100 . The shape of the first contoured surface 211 is adapted to the shape of the outer side surface of the guide groove 100 .

[0039] like Figures 7 to 9 As shown, the second jig 220 includes a second profiling surface 221, which is used to support the inner side surface of the guide groove 100. The shape of the second profiling surface 221 is adapted to the shape of the inner side surface of the guide groove 100. The first jig 210 cooperates with the second jig 220 so that the first profiling surface 211 and the second profiling surface 221 form a punching groove 201 for positioning the guide groove 100.

[0040] Before the punching operation, the end of the guide groove 100 to be punched is placed in the punching groove 201 formed by the cooperation of the first jig 210 and the second jig 220. The outer side surface of the guide groove 100 is positioned and supported by the first contour surface 211 of the first jig 210, and the inner side surface of the guide groove 100 is positioned and supported by the second contour surface 221 of the second jig 220. The part of the end of the guide groove 100 to be punched that is not supported and positioned is exposed on the punching side, which facilitates the subsequent punching operation.

[0041] like Figure 10 and Figure 11As shown, the punching piece 310 has a punching blade 311, and the punching blade 311 of the punching piece 310 is in contact with the punching side of the first jig 210 or the second jig 220. Under the action of an external driving source, the punching piece 310 can perform reciprocating motion, and the extension line of the punching groove 201 along the length direction of the punching groove 201 intersects with the movement path of the punching blade 311, so that the punching blade 311 can cut off the part of the guide groove 100 exposed on the punching side.

[0042] During punching, an external drive source drives the punching member 310 to move back and forth along the direction of cutting the punching groove 201. The reciprocating motion of the punching member 310 removes the portion of the guide groove 100 exposed on the punching side, thereby punching out two notches at different positions in one operation while also preventing deformation of the guide groove 100. The present invention's structure for punching the guide groove 100 with an out-of-position notch optimizes the previous two punching operations into a single one, improving production cycle time and reducing the number of punching equipment, thereby improving efficiency and saving manpower and material resources.

[0043] In some specific embodiments, Figure 7 and Figure 8 As shown, the first jig 210 and the second jig 220 are stacked up and down, and the punching groove 201 is located between the first jig 210 and the second jig 220, wherein the punching side of the first jig 210 is flush with the punching side of the second jig 220, the punching side of the first jig 210 is adjacent to the first profiling surface 211, and the punching side of the second jig 220 is adjacent to the second profiling surface 221.

[0044] In the embodiment of the present application, the punching side of the first jig 210 is perpendicular to the first profiling surface 211, and the punching side of the first jig 210 is flush with the end of the punching groove 201; the punching side of the second jig 220 is perpendicular to the second profiling surface 221, and the punching side of the second jig 220 is flush with the end of the punching groove 201.

[0045] During punching, the portion of the guide groove 100 that is not supported by the first jig 210 or the second jig 220 is exposed on the movement path of the punching piece 310. When the punching piece 310 moves to a position close to the punching groove 201 with the first jig 210 or the second jig 220, under the shearing and extrusion action of the punching piece 310 and the first jig 210 or the second jig 220, the portion of the guide groove 100 that is not supported by the first jig 210 or the second jig 220 is removed to achieve punching of the notch.

[0046] In some embodiments, as Figure 3 and Figure 4As shown, the eccentric notch punching structure of the guide groove 100 also includes a mounting seat 400, the first jig 210 and the second jig 220 are both fixed to the mounting seat 400, and the punching piece 310 is slidably set on the mounting seat 400. The mounting seat 400 serves as a mounting reference for fixing the first jig 210 and the second jig 220 to ensure accurate positioning of the guide groove 100 during punching to ensure the accuracy of the punching size and shape; the mounting seat 400 also plays a guiding role to limit the movement direction of the punching piece 310 to ensure that the notch can be accurately removed each time the punching is performed.

[0047] In some specific embodiments, Figure 12 and Figure 13 As shown, the mounting base 400 is provided with a guide groove 420, and the punching piece 310 is inserted into the guide groove 420. A portion of the punching piece 310 can be configured to match the guide groove 420 so that the punching piece 310 can slide within the guide groove 420. At the same time, the cross-sectional shape of the guide groove 420 should be configured to be non-circular so as to limit the rotation of the punching piece 310 during movement. In some specific embodiments, the portion of the punching piece 310 inserted into the guide groove 420 has a clearance fit with the guide groove 420, and the cross-sectional shape of the guide groove 420 is polygonal, which can be a triangle, a rectangle, etc.

[0048] In some embodiments, the mounting base 400 is provided with a resilient member 320, and the punching member 310, under the action of the resilient member 320, tends to move away from the punching slot 201. Generally, a driving source can automatically return the punching member 310 to its original position after the punching operation, but the punching member 310 is not directly connected to the driving source. Therefore, if the punching member 310 cannot automatically return to its original position, it is easy to affect the next punching operation of the guide slot 100.

[0049] The resilient element 320 is configured to automatically return the punching element 310 to its original position after the external driving source is removed, so that it does not interfere with the material discharge from the guide groove 100. Specifically, the resilient element 320 forces the punching element 310 to move away from the longitudinal extension of the punching groove 201. During the punching operation, the external driving source drives the punching element 310 toward the punching groove 201 and compresses the resilient element 320. When the external driving source is removed, the resilient force generated by the resilient element 320 drives the punching element 310 back to its original position.

[0050] In some embodiments, the resilient member 320 may be a spring, which may be a compression spring or a nitrogen gas spring.

[0051] In some embodiments, the guide groove 100 unequal-position notch punching structure further includes a punching block 330, which is connected to the punching member 310. One end of the resilient member 320 abuts against the mounting seat 400, while the other end abuts against the punching block 330. The punching block 330 is used to interface with an external driver, thereby concentrating the driving force of the external drive source on the punching member 310. Furthermore, one end of the resilient member 320 is mounted on the mounting seat 400, while the other end abuts against the punching block 330. Because the punching block 330 is connected to the punching member 310, when the force from the external drive source disappears, the resilient member 320 drives the punching block 330 back to its original position, and the punching member 310 also returns to its original position.

[0052] In some specific embodiments, the resilient member 320 is a spring. Two resilient members 320 are provided. The two resilient members 320 are distributed on both sides of the punching member 310 . The mounting seat 400 is provided with a positioning hole 440 for positioning the spring.

[0053] In some other embodiments, the rebound member 320 may also be disposed between the mounting seat 400 and the punching member 310 . The punching member 310 may be larger than the guide slot 420 , and the spring presses against the portion of the punching member 310 that is larger than the guide slot 420 .

[0054] In the embodiment of the present application, the guide groove 420 passes through both ends of the mounting seat 400, the punching piece 310 is inserted from one end of the guide groove 420, and the other end of the guide groove 420 serves as a waste discharge port to prevent the punching waste from affecting the next punching.

[0055] In some embodiments, the mounting seat 400 is further provided with a fastener for limiting the punching piece 310 from being separated from the guide groove 420 . The fastener may be a gasket fixed to the mounting seat 400 by screws.

[0056] In some embodiments, the mounting base 400 is further provided with a mounting groove 410. The first jig 210 and the second jig 220 are sequentially stacked in the mounting groove 410 and then fastened to the mounting base 400 by fasteners. The mounting groove 410 is connected to the guide groove 420, and the punching groove 201 is connected to the guide groove 420. The connection between the mounting groove 410 and the guide groove 420 facilitates the cooperation between the punching sides of the first jig 210 and the second jig 220 and the punching blade 311 of the punching piece 310 to complete the punching operation, and also facilitates the processing of the mounting groove 410 and the guide groove 420.

[0057] The first fixture 210 and the second fixture 220 stacked in the mounting groove 410 are locked by fasteners, which makes disassembly and installation very convenient and facilitates subsequent maintenance and replacement. Specifically, the fasteners can be screws or washers locked to the mounting base 400 by screws.

[0058] Among them, the punching groove 201 is connected to the guide groove 420, and the width of the guide groove 420 is set to the length of the guide groove 100 exposed on the punching side. On the one hand, the guide groove 420 can play a positioning and limiting role, and can accurately locate the length of the guide groove 100 to be punched, thereby effectively improving production efficiency.

[0059] In some embodiments, the mounting groove 410 has a positioning groove 430, and both the first fixture 210 and the second fixture 220 are provided with a positioning structure 202 adapted to the positioning groove 430. Specifically, the positioning structure 202 is provided on both sides of the first fixture 210 and the second fixture 220. The positioning structure 202 can be a raised block or a raised strip. The cooperation between the positioning structure 202 and the positioning groove 430 enables the rapid installation of the first fixture 210 or the second fixture 220.

[0060] The present application also provides a punching device, which includes the above-mentioned guide groove 100 eccentric notch punching structure. By using the punching device in conjunction with the guide groove 100 eccentric notch punching structure, it is possible to complete the punching of two notches of the guide groove 100 at one time, effectively improving production efficiency.

[0061] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
