Description

Technical Field

[0001] The invention relates to the field of flanging equipment, in particular to an end cover flanging integrated forming machine. Background Art

[0002] In order to meet the needs of quick loading and unloading of the cylinder and ensure the stability and sealing of the connection, special end covers are usually installed on the end faces of the cylinder and flanging is performed on them. Flanging refers to folding or deforming the edge of the end cover to form a raised edge, thereby increasing the area of ​​the connection area and strengthening the connection firmness and sealing between the cylinder and the end cover.

[0003] Existing flanging equipment usually uses a combination of a concave lower die seat and a convex upper die seat to clamp the panel, and the panel is punched into the required flanging shape by the punching force applied by the punch press. This technology has an advantage in mass production due to its high efficiency, and is particularly suitable for flanging requirements with simple and regular shapes. However, its significant limitation is that the mold is too customizable. Almost every different end cap flanging design requires a dedicated mold pair to match, including redesigning and manufacturing the concave lower die seat and the convex upper die seat. This not only greatly reduces the versatility of the mold, but also increases the production cost and cycle. Whenever the product is updated or the market demand changes, it is necessary to go through a cumbersome mold replacement process. In addition, for flanging tasks with thin plate materials or complex shapes, this stamping flanging technology often cannot guarantee the quality of the flanging, and there may be problems such as non-vertical flanging, uneven height, surface roughness, and even cracks, which affects the overall quality and durability of the product.

[0004] In addition, another common process is to weld strip plates to the edge of the panel to form an end cap. The pre-welding pretreatment process of this technology is complex and time-consuming, including strict cleaning, precise alignment and firm fixation, which not only increases the complexity of the process, but also increases the time cost. More importantly, the thermal stress generated during the welding process may cause deformation of the panel and strip plates, affecting the dimensional accuracy and shape consistency of the flange. If the post-welding treatment is improper, such as incomplete cleaning of welding slag and failure to perform necessary anti-corrosion treatment, the welding part will be more susceptible to corrosion and rust in future use. In addition, welding flanging technology has strict requirements on the weldability of materials, which limits its scope of application. For materials with poor welding performance such as high-alloy steel and titanium alloy, welding flanging technology is often not the best choice, and other more suitable processing methods need to be sought.

[0005] Based on this, it is necessary to provide an end cap flanging machine that can adapt to end cap flanging processing of different sizes and has good flanging quality. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The end cap flanging integrated forming machine of the present invention integrates a flanging component, a positioning component, a trimming component, a stabilizing component and a central control component, so that the end cap panel immediately enters the trimming component for trimming and compacting after being flanging by the cone wheel. Continuous operation helps to maintain the smoothness and uniformity of the flanging part. At the same time, a stabilizing component is provided to apply appropriate supporting force to the end cap panel to ensure that the panel at the junction of the flanging remains flat. The positioning component accurately identifies the edge of the end cap during the entire flanging process to ensure the accuracy and consistency of the flanging. The data provided by the positioning component supports the central control component to coordinate and adjust each component in real time to ensure the stability of the flanging process and the flanging quality.

[0029] 2. In the process of spinning and flanging the end cover panel by the downward pressure provided by the cone wheel, a guide column is added under the end cover panel to provide stable support, which effectively prevents the end cover panel from moving or shaking unnecessarily under the downward pressure of the cone wheel, and prevents the panel from deforming or twisting due to uneven force. It plays a key role in maintaining the flatness and shape accuracy of the flanging area. The precise positioning and stable support of the guide column enable the cone wheel to spin and flanging more accurately along the predetermined trajectory, reducing errors and deviations in the processing process.

[0030] 3. Since the shape, size and material of the end cover panel may be different in the flanging process, the cone wheel is required to be able to move flexibly in multiple directions to adapt to different processing requirements. The present invention introduces lateral and longitudinal sliding components to enable the cone wheel to achieve two-degree-of-freedom movement, more accurately control the pressure distribution, flanging angle and shape during the processing, and thus more accurately position and operate the end cover panel, and the applicability and flexibility of the equipment are higher; the guide column is slidably installed on the guide component to achieve the same lateral movement function as the cone wheel. When the guide column can be dynamically adjusted with the movement of the cone wheel, it can more effectively disperse and balance the force on the end cover panel, thereby further reducing the risk of panel deformation, without the need to frequently replace or adjust the equipment, and reducing production costs.

[0031] 4. A slot is set on the positioning component. By flexibly adjusting the position of the support rod in the slot, the actual working length of the positioning rod can be effectively changed, so that the positioning wheel has the function of free movement in the longitudinal direction. Under the coordinated work of the positioning plate and the second hydraulic drive device, the positioning wheel can be accurately controlled in two degrees of freedom, which can meet the positioning requirements of workpieces at different heights and positions, greatly enhancing its flexibility and practicality in practical applications.

[0032] 5. The edge trimming assembly provides two opposite supporting forces through the edge trimming wheel and the auxiliary wheel, thereby compacting the flanged part of the end cover panel, enhancing the tightness and strength of the flange, reducing burrs and unevenness during the flange process, and making it smoother and more uniform.

[0033] 6. The stabilizing component monitors the reaction force of the end cover panel in real time. When it exceeds the set threshold, the central control component drives the position of the stabilizing wheel by controlling the fourth and fifth hydraulic cylinders, accurately controls the force applied by the stabilizing wheel to the end cover, and provides appropriate support force to reduce friction and wear between the end cover and the rolling wheel, and prevent instability caused by high-speed rotation of the end cover, such as vibration or offset, thereby enhancing the stability of the entire system. The ability to adjust the position of the stabilizing wheel enables the equipment to adapt to end covers of different sizes and weights, increasing the flexibility and applicability of the equipment.

DETAILED DESCRIPTION

[0047] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given here are only used to illustrate and explain the present invention, and cannot be used to limit the present invention.

[0048] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also have other implementations and variations thereof. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] like Figures 1 to 12 As shown, an end cover flanging integrated forming machine of this embodiment includes:

[0050] like Figure 2As shown, a mounting platform 100, support frames 110 are fixedly mounted on both sides of the top surface of the mounting platform 100, a crossbeam 120 is provided on the top surface of the support frame 110, a first hydraulic drive device 130 is mounted on the center of the crossbeam 120, and an output end of the first hydraulic drive device 130 is connected to a first telescopic rod 140;

[0051] Since the mounting platform 100, the support frame 110 and the crossbeam 120 are the basis for installing various components and supporting them for various movements, it should be ensured that they have sufficient load-bearing capacity and stability. In addition to considering the geometric dimensions and weight distribution during the design phase, the dynamic load should also be considered, and engineering software such as finite element analysis should be used to simulate the strength and stiffness to optimize the design of the mounting platform 100, the support frame 110 and the crossbeam 120. They can usually be made of solid steel or cast iron, which can effectively resist mechanical stress and impact loads and ensure that no deformation occurs during operation.

[0052] like Figure 3 As shown, the die assembly 200 includes an upper die 210 and a lower die 220. The upper die 210 is connected to the first telescopic rod 140 through a first rotating disk 230, and the lower die 220 is connected to the connecting rod 150 fixed on the top surface of the mounting platform 100 through a second rotating disk 240. The centers of the upper die 210 and the lower die 220 coincide with the axis of the first telescopic rod 140.

[0053] When in use, the panel is placed in the die assembly 200 manually or by a robot, and the panel positioning is assisted by laser positioning technology, specifically, the panel is scanned by a laser scanner to capture the three-dimensional data of its shape and installation position. The circumference direction of the panel is accurately measured by laser radar technology and key points are marked, and then the actual axis position of the panel is calculated. The central control system generates a deviation report based on the deviation between the actual axis position and the axis position of the lower die 220, and instructs the operator to make adjustments to ensure the correct positioning of the panel. After the positioning is completed, the first hydraulic drive device 130 drives the first telescopic rod 140 to extend, driving the upper die 210 to move downward, clamping the panel for flanging processing, wherein the centers of the upper die 210 and the lower die 220 coincide with the axis of the first telescopic rod 140, ensuring the symmetry and accuracy of the flanging process, helping to form a more uniform and stronger flanging, and improving the flanging quality.

[0054] like Figure 4As shown, the flanging assembly 300 includes a first fixed platform 310 fixedly mounted on the top surface of the mounting platform 100, a transverse sliding component 320, a longitudinal sliding component 330 and a guide component 340. The transverse sliding component 320 and the guide component 340 are both slidably mounted on the first fixed platform 310, the longitudinal sliding component 330 is slidably mounted on the transverse sliding component 320, a cone wheel 331 is slidably mounted on the side of the longitudinal sliding component 330 facing the die assembly 200, a guide column 341 is slidably mounted on the guide component 340, the guide column 341 is tangent to the inside of the upper die 210, and the moving direction of the guide column 341 relative to the guide component 340 is parallel to the moving direction of the longitudinal sliding component 330 relative to the transverse sliding component 320;

[0055] The lateral sliding component 320 provides the cone wheel 331 with lateral movement relative to the axis of the die assembly 200. Similarly, the longitudinal sliding component 330 provides the cone wheel 331 with longitudinal movement perpendicular to the panel, so that the cone wheel 331 can achieve two degrees of freedom of movement, can accurately locate and adapt to the edges of panels of different shapes and sizes and guide the flanging process. The guide component 340 provides the guide column 341 with lateral movement relative to the axis of the die assembly 200, so that the lateral distance between it and the cone wheel 331 can be adjusted based on the thickness of the flanging panel. The guide column 341 of this embodiment is cylindrical. In the process of the cone wheel 331 applying pressure to the upper surface of the stamping panel and gradually bending its edge to form a flanging, the guide column 341 always effectively and firmly supports the lower surface of the panel. The direction of the supporting force provided by it is exactly opposite to the direction of the pressure applied by the cone wheel 331, which helps to achieve a more uniform and consistent flanging effect and effectively avoids the problem of panel deformation or damage caused by uneven force distribution.

[0056] like Fig. 9 As shown, the positioning assembly 400 includes a plurality of brackets 410 fixedly mounted on the top surface of the mounting platform 100, a second hydraulic driving device 420 is fixedly mounted on the top of the bracket 410, a second telescopic rod 430 is provided at the output end of the second hydraulic driving device 420, the output end of the second telescopic rod 430 is fixedly connected to the positioning plate 440, a positioning rod 450 is inserted on the top surface of the positioning plate 440, and a positioning wheel 453 is sleeved on the free end of the positioning rod 450;

[0057] like Fig.11As shown, the edge trimming assembly 500 includes a second fixed platform 510 fixedly mounted on the mounting platform 100, a first sliding component 520 and a second sliding component 530, the first sliding component 520 and the second sliding component 530 are both slidably mounted on the second fixed platform 510, the first sliding component 520 is provided with a third hydraulic driving device 521, the output end of the third hydraulic driving device 521 is provided with an edge trimming wheel 522, the edge trimming wheel 522 is tangent to the outside of the upper die 210, the second sliding component 530 is provided with a fourth hydraulic driving device 531, the output end of the fourth hydraulic driving device 531 is provided with an auxiliary wheel 532, the auxiliary wheel 532 is tangent to the inside of the upper die 210, and the auxiliary wheel 532 and the edge trimming wheel 522 are arranged on the same horizontal plane;

[0058] The third hydraulic drive device 521 controls the horizontal movement of the edge trimming wheel 522, and the fourth hydraulic drive device 531 controls the horizontal movement of the auxiliary wheel 532. By adjusting the distance and position between the edge trimming wheel 522 and the auxiliary wheel 532, the flanging requirements of end cover panels of different sizes and shapes can be met. The edge trimming wheel 522 and the auxiliary wheel 532 respectively provide two opposite supporting forces, thereby compacting the flanging part of the end cover panel, which not only enhances the tightness and strength of the flanging, but also helps to reduce burrs and unevenness during the flanging process, and improve the surface quality of the flanging part. By compacting the flanging part, the surface quality of the flanging area can be significantly improved, making it smoother and more uniform.

[0059] like Fig.12 As shown, the stabilizing assembly 600 includes a third fixed platform 610, a third sliding component 620 and a fourth sliding component 630 fixedly mounted on the top surface of the mounting platform 100. The third sliding component 620 is slidably mounted on the third fixed platform 610, and the fourth sliding component 630 is slidably mounted on the third sliding component 620. The third sliding component 620 drives the fourth sliding component 630 to move horizontally along the radial direction of the lower die 220. A stabilizing wheel 631 is slidably mounted on the fourth sliding component 630, and the fourth sliding component 630 drives the stabilizing wheel 631 to move vertically.

[0060] During the spinning and flanging process, the stabilizing assembly 600 helps to reduce the pressure effect of the cone wheel 331 on the end cover panel, especially at the flanging junction. The stabilizing wheel 631 applies appropriate supporting force to the end cover panel during the flanging process to ensure that the panel at the flanging junction remains stable and the end cover panel remains horizontal and flat during the flanging process, preventing deformation of the panel due to uneven pressure, helping to avoid wrinkles, cracks or other defects at the flanging junction during the flanging process, thereby ensuring the quality of the flanging.

[0061] The central control component 700 is arranged on the mounting platform 100 and is used for automatic control of the end cover flanging integral molding machine.

The rotation direction of the stabilizing wheel 631 is perpendicular to the plane of the upper die 210. The output end of the fifth hydraulic cylinder 632 is connected to the seventh slide block 634. Under the driving action of the fifth hydraulic cylinder 632, the seventh slide block 634 drives the stabilizing wheel 631 to move relative to the fifth slide rail 633. The fifth slide rail 633 is fixedly installed on the second bottom plate 635. The second bottom plate 635 is fixedly installed on the sixth slide block 623. The fourth hydraulic cylinder 621 and the fifth hydraulic cylinder 632 are both electrically connected to the central control component 700.

[0063] Furthermore, a pressure sensor (not shown) electrically connected to the central control assembly 700 is provided in the stabilizing wheel 631 for real-time monitoring of the reaction force F of the end cap. The reaction force F should be within a threshold range and satisfy the following formula:
