Description

Technical Field

[0001] This invention relates to the field of new energy vehicle processing equipment technology, and in particular to an integrated machine for stamping and riveting automotive guide grooves. Background Technology

[0002] Sealing strips for car doors, windows, and other parts typically require metal or plastic clips to be installed in specific locations to secure them to the car body. Simultaneously, both ends of the strip need to be cut according to the structure of the installation location, commonly either vertically (vertical cut) or at a certain angle (beveled cut), to ensure both aesthetics and sealing performance after assembly. In traditional manufacturing processes, riveting the clips, cutting the middle section, and performing the vertical and bevel cuts at both ends of the strip usually need to be completed in steps on multiple machines or at multiple workstations, which has the following disadvantages:

[0003] 1. The production process is fragmented, requiring multiple loading and unloading and positioning steps, resulting in numerous production steps, complicated operation, and difficulty in meeting the needs of large-scale production, thus leading to low production efficiency.

[0004] 2. When the adhesive strips are transferred between different devices, especially those with curved arcs, it is difficult to ensure consistent positioning each time. This leads to cumulative errors in the rivet position, cutting position, and angle of the clips, resulting in poor positioning accuracy and affecting the product qualification rate.

[0005] 3. Using multiple devices requires a large space and more operators and maintenance personnel, increasing equipment and labor costs.

[0006] 4. The connection between processes relies heavily on manual labor, which is labor-intensive and makes it difficult to achieve intelligent control of the production process, resulting in a low degree of automation. Summary of the Invention

[0034] The invention will now be further described with reference to the accompanying drawings.

[0035] A car guide groove punching and riveting integrated machine, reference Figure 1 , Figure 2 The system includes a frame 1, externally equipped with a lighting and protective railing. A servo transfer mechanism 2 is mounted inside the frame 1, located at the top. The servo transfer mechanism 2 includes a base plate on which two elongated support platforms, designated as a first station 5 and a second station 6, are arranged parallel to each other via high-precision linear guides. Each support platform is used to place and position the adhesive strip to be processed. The drive component of the servo transfer mechanism 2 includes a longitudinal movement servo assembly 21, consisting of a servo motor, a ball screw, and a cooperating nut slider, which drives the mounting base of the entire central cutting and riveting device 8 to move precisely between the first station 5 and the second station 6 along the Y-axis.

[0036] Above the first station 5, an end-cutting device 7 is installed via a first lateral movement servo assembly 22. The structure of the first lateral movement servo assembly 22 is similar to that of the longitudinal movement servo assembly 21, driving the end-cutting device 7 to move along the X-axis (perpendicular to the length of the rubber strip) to accommodate rubber strips of different widths or to perform double-sided end processing. Similarly, above the second station 6, an end-bevel cutting device 9 is installed via a second lateral movement servo assembly 23. A hydraulic unit 3 is integrated on the side of the frame 1, containing a hydraulic pump, oil tank, control valve group, etc., providing power to the hydraulic cylinders requiring large cutting forces. The electrical control device 4 is typically a control cabinet equipped with a PLC (Programmable Logic Controller) and a human-machine interface (HMI), centrally controlling the actions of all motors, cylinders, and hydraulic valves.

[0037] Reference Figure 3 , Figure 4 The end-cutting device 7 specifically includes an end-cutting pressing cylinder 71 fixed to the slider of the first transverse movement servo assembly 22 via a mounting plate. The piston rod of the end-cutting pressing cylinder 71 points downward and is connected to an end-cutting pressing frame 72. An end cutter 73 is bolted to the bottom of the end-cutting pressing frame 72, and the blade shape of the end cutter 73 matches the required vertical end face. End guide rods 77 extend through both sides of the end-cutting pressing frame 72, and the end guide rods 77 guide and stabilize the movement of the pressing frame 72. Below the end cutter 73 at the first station 5, an end-cutting base 78 is provided, and an end-cutting mold base 74 is provided on the end-cutting base 78. The upper surface shape of the end-cutting mold base 74 matches the curvature of the lower surface of the rubber strip. The cylinder body of the end-cutting overall curvature adjustment cylinder 75 is hinged to the end-cutting base 78. By controlling the extension and retraction of the end-cutting overall curvature adjustment cylinder 75, the end-cutting base 78 can swing around its axis at a small angle, thereby making the end-cutting mold base 74 fit with the actual curvature of the rubber strip. On the side of the end-cutting mold base 74, there is an end-positioning cylinder 76, whose piston rod head is equipped with a positioning block, which can extend after the end of the rubber strip is delivered into position and press against the end face of the rubber strip for precise positioning. At the lower end of the end-cutting pressing frame 72, next to the end cutter 73, there is also an end-cutting material stabilizing block 79. When pressing down, it contacts the rubber strip before the end cutter 73 and presses it firmly onto the mold base 74 to prevent the rubber strip from moving during cutting.

[0038] Reference Figure 5 , Figure 6The central cutting and riveting device 8 is mounted on the slider of the longitudinal movement servo assembly 21. It includes a central cutting and pressing cylinder 81 and a central pressing frame 82. A central cutter 83 and a pressing riveting block 84 are mounted side by side on the central pressing frame 82. The central pressing frame 82 is also guided by a central guide rod 88 that passes through it. A central cutting and riveting base 89 is provided at the first station 5. A central cutting die base 85 corresponding vertically to the central cutter 83 is fixed on the central cutting and riveting base 89. The central cutting die base 85 has an opening... There is a cutting groove that matches the middle cutter 83. Next to the middle cutting die 85, there is a riveting die 86 with a cavity for accommodating the clip on the upper part. The riveting top cylinder 87 is installed below the base 89. Its piston rod can push up a top rod, which cooperates with the lower riveting block 84 above to complete the riveting of the clip placed in the cavity of the riveting die 86 (squeezing and deforming the clip to hold the rubber strip tightly). The lower end of the middle lower pressure frame 82 is also provided with a middle cutting material stabilizing block 801, which is used to press the rubber strip when it is cut into two sections.

[0039] Reference Figure 7 , Figure 8 The end beveling device 9 is fixedly mounted on the slider of the second transverse movement servo component 23 via the end beveling base 96, enabling the entire device to perform high-precision position adjustment along the width direction (X-axis) of the rubber strip to adapt to the positioning requirements of rubber strips of different specifications or double-sided processing. One side of the end beveling base 96 is connected to the piston rod head of the end beveling arc adjustment cylinder 94. The end beveling arc adjustment cylinder 94 can drive the entire end beveling base 96 and all components mounted on it to swing precisely at a small angle, which can change relative to the vertically placed sidewall of the rubber strip, thereby processing a continuously adjustable inclined cutting surface at the end of the rubber strip, perfectly adapting to the angle requirements of the guide groove mounting surface of different vehicle models.

[0040] An end-beveling rubber strip fixing seat 95 is fixedly installed above the end-beveling base 96 to support and position the rubber strip. The end-beveling mold base 91 is a box structure, and an end-beveling module 97 that can slide along the cutting direction (i.e., the preset tilt direction) is provided inside. The end-beveling module 97 has a blade mounting groove; the end-beveling blade 93 is fastened to the blade mounting groove of the end-beveling module 97 through its blade handle. The cutting edge angle of the end-beveling blade 93 is consistent with the tilt angle of the end face of the rubber strip to be processed, ensuring the beveling quality of the end face of the rubber strip. The end-beveling hydraulic cylinder 92 is installed on the outer wall of the end-beveling mold base 91. When the hydraulic unit supplies oil to the hydraulic cylinder 92 under the command of the electronic control device 4, its piston rod drives the end-beveling module 97 and the end-beveling blade 93 to move forward at high speed and smoothly along the precision guide rail inside the end-beveling mold base 91, completing the punching and cutting action on the end of the rubber strip placed on the end-beveling rubber strip fixing seat 95.

[0041] like Figure 6 As shown, to further improve cutting quality, especially to prevent deformation or uneven cuts when cutting the side of curved rubber strips, a cutting auxiliary mold core block 100 is embedded inside the end cutting mold base 74 and / or the middle cutting mold base 85. The contour of the cutting auxiliary mold core block 100 closely matches the inner cavity shape of the rubber strip at the cutting point. The cutting auxiliary mold core block 100 is finely adjusted by a mold base adjustment assembly, which includes a mold core block fixing plate 101 fixed to the mold base body, a mold core block adjusting rod 102 passing through the fixing plate and pressing against the back of the cutting auxiliary mold core block 100, and a mold core block adjusting spring 103 sleeved between the adjusting rod 102 and the fixing plate 101. By turning the adjusting rod 102, the spring 103 can be preloaded, thereby giving the cutting auxiliary mold core block 100 a continuous and flexible ejection force, so that it can always tightly support the rubber strip during cutting.

[0042] The working principle of this invention is as follows: First, the adhesive strip is placed in the first work station. The first lateral movement servo component 22 drives the end cutting device 7 to move to the corresponding position at the end of the adhesive strip. The end positioning cylinder 76 extends, and its positioning block abuts against the end face of the adhesive strip to complete the length direction positioning. The servo transfer mechanism 2 moves the adhesive strip, causing the middle riveting part of the adhesive strip to move to the middle cutting riveting device 8, while both ends of the adhesive strip are placed on the end cutting device 7. The clip is placed into the cavity of the riveting mold base 86. The end cutting overall arc adjustment cylinder 75 drives the end cutting base 78 to swing, so that the end face cutting mold base 74 corresponds and matches the arc of the adhesive strip. Subsequently, the riveting upper lifting cylinder 87 and the lower pressing riveting block 84 work together to complete the clip riveting; at the same time, the middle cutting lower pressing cylinder 81 drives the middle lower pressing frame 82 to move down. After the middle cutting stabilizing block 801 presses the rubber strip, the middle cutter 83 and the middle cutting mold base 85 cooperate to cut the rubber strip into two sections. The end cutting pressing cylinder 71 can also operate simultaneously with the middle cutting and riveting, driving the end cutting pressing frame 72 to move downward, so that the end cutting stabilizing block 79 presses the rubber strip first. Then, the end cutter 73 and the end cutting mold base 74 cooperate to complete the vertical cutting. After cutting, the end cutting pressing cylinder 71 drives the end cutting pressing frame 72 to reset, and the end positioning cylinder 76 retracts. The longitudinal movement servo component 21 drives the middle cutting and riveting device 8 to move above the second station 6. The servo transfer mechanism 2 transfers the cut rubber strip segment from the first station 5 to the second station 6. The second transverse movement servo component 23 drives the end beveling device 9 to move to the corresponding position of the rubber strip to be processed end. The end beveling arc adjustment cylinder 94 drives the end beveling base 96 to swing, adjusting the cutting angle of the end beveling blade 93. After the rubber strip is positioned and clamped on the end beveling rubber strip fixing seat 95, the end beveling hydraulic cylinder 92 drives the end beveling module 97 and the end beveling blade 93 to move along the inclined trajectory to complete the bevel cutting.

[0043] After processing is completed, all devices are reset, and the finished product is exported from the second station 6. The first station 5 can then begin feeding and processing the next strip of adhesive, entering the next cycle.

[0044] During the cutting process, the cutting auxiliary die core block 100 in the end cutting die base 74 and the middle cutting die base 85 is always pressed against the inner wall of the rubber strip under the action of the die core block adjusting spring 103, providing support for cutting.
