Description

Technical Field

[0001] The utility model belongs to the field of template processing, and specifically discloses a template segmented bending device. Background Art

[0002] In the traditional mold processing process, the forming of multi-bending components often adopts a one-time forming technical path, that is, all the predetermined bending processes are completed in a single operation. However, when it comes to complex products that require multiple bends, the limitations of this forming method become apparent: since the internal stress distribution of the material is extremely uneven during the continuous high-strength deformation process, especially at the intersection of multiple bends, the stress concentration phenomenon is particularly serious, which easily leads to material fracture or damage.

[0003] A bending and stripping structure for a mold with the patent application number CN202021476350.2 includes a lower mold. The lower mold includes a lower template, a lower backing plate, a lower mold base, and a lower support plate arranged in sequence from top to bottom. The lower template is fitted with a pressing block insert for bending. The bending and stripping structure includes a stripping pin. The stripping pin includes a head and a rod portion. The radius of the head is greater than that of the rod portion. The pressing block insert is provided with a sliding hole through which only the rod portion of the stripping pin can pass. The lower backing plate is provided with a through hole for the head of the stripping pin to slide up and down. A return spring is arranged between the stripping pin and the lower mold base. One end of the return spring is fixedly connected to the head of the stripping pin, and the other end of the return spring is fixedly connected to the lower mold base; in the open mold state, the rod portion of the stripping pin extends out of the top surface of the pressing block insert, and the return spring is in a non-compressed state. The above device synchronously bends the workpiece with the pressing block insert, and it is also easy to cause the workpiece to break. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when the bending device processes a workpiece in the above-mentioned prior art, synchronously processing the workpiece easily causes the workpiece to be bent to break.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A template segmented bending device includes an upper template, a lower template, a floating material supporting part, a bending assembly, and a spring; the upper template and the lower template are arranged opposite to each other, and the upper template is located directly above the lower template; the bending assembly is used for bending a workpiece to be processed, the bending assembly is installed in the upper template and the lower template, springs with different lengths are installed between the bending assembly and the upper template and the lower template, the floating material supporting part is installed in the lower template, and the same spring is also installed between the floating material supporting part and the lower template.

[0007] Furthermore, the bending assembly includes an upper die bending part, a lower die bending part, a stripping bending part and a punch fixed bending part. A plurality of upper die bending parts are provided. The upper die bending part is installed in the upper template through the spring. The stripping bending part is installed between the upper die bending parts. The stripping bending part is installed in the upper template through the spring. The punch fixed bending part is provided on the outside of the upper die bending part, and the punch fixed bending part is welded in the upper template.

[0008] The setting of multiple upper die bending parts, combined with springs of different lengths, can achieve precise bending of specific areas of the workpiece, ensuring that each bending part can achieve the bending angle and position accuracy required by the design. The spring connection between the upper die bending parts and the punch fixed bending parts provides a stable supporting force. Even if the material hardness changes or the thickness is uneven during the processing, it can maintain a good bending effect and prevent the workpiece from shifting or deforming. The setting of the demoulding bending parts, especially the welding connection with the upper template, ensures the smooth demoulding of the workpiece after bending, avoids surface scratches or bending angle deviation caused by adhesion, and simplifies the subsequent demoulding process. By adjusting the number and position of the upper die bending parts, the punch fixed bending parts, and the elastic force parameters of the spring, it can flexibly cope with workpieces of different sizes, shapes and material properties, thereby improving the versatility and processing efficiency of the equipment.

[0009] Furthermore, a plurality of the lower die bending parts are provided, and the springs are respectively installed at the bottom of the lower die bending parts, and the lengths of the springs are respectively 3 cm, 5 cm and 7 cm.

[0010] Springs of different lengths mean different elastic recovery forces, which allows the bending process to start with a slight preload and gradually increase to full bending. This progressive bending method helps the material gradually adapt to the required deformation, reduce stress concentration, and avoid the risk of cracks and fractures. By adjusting the length of the spring, the distribution of the bending force can be controlled, so that the workpiece is subjected to more uniform force during the bending process, reducing material damage caused by excessive local stress, and improving product quality and consistency. Springs of different lengths can be personalized according to the material, thickness and required bending angle of the workpiece, so that the equipment can flexibly respond to various processing needs and improve processing flexibility and efficiency. Precisely controlled bending force and progressive bending process help improve bending accuracy and reduce dimensional deviation, which is particularly important for industrial products with high precision requirements. The buffering effect of the spring reduces the impact load of the mold during the bending process, which helps reduce mold wear, extend mold service life, and reduce maintenance costs.

[0011] Furthermore, a plurality of the floating material supporting parts are arranged on the lower template, and the spring is installed between the floating material supporting parts and the lower template.

[0012] Before bending, the lifting and supporting part can stably support the workpiece in place, ensuring the accurate positioning of the workpiece during the entire processing, reducing the processing errors caused by position deviation. The presence of the spring plays a role in shock absorption and buffering, which can absorb the impact force generated during bending, protect the workpiece from damage, and at the same time reduce the wear of the mold and extend its service life. Springs of different lengths can provide corresponding supporting forces according to different parts and bending degrees of the workpiece, achieving a progressive supporting effect, helping the workpiece to be evenly stressed, and avoiding deformation or damage caused by excessive local stress. After bending, the lifting and supporting part can use the elastic force of the spring to help the workpiece smoothly escape from the mold, reducing the friction between the workpiece and the mold, avoiding scratching the surface of the workpiece, and at the same time simplifying the demoulding steps and improving production efficiency. By adjusting the position of the lifting and supporting part and the elastic coefficient of the spring, it can flexibly cope with workpieces of different shapes and sizes, increasing the adaptability and processing range of the equipment.

[0013] Furthermore, bending teeth are provided at the bottom of the upper die bending part and the bottom of the punch fixed bending part, and bending protrusions are provided at the top of the lower die bending part. Adjacent bending protrusions form bending grooves corresponding to the bending teeth.

[0014] The precise matching of the bending teeth and the bending grooves can ensure the accurate positioning of the workpiece during bending, achieve precise control of the bending angle and position, and improve the processing accuracy. The contact surface design of the bending teeth and the bending grooves can evenly distribute the bending force, reduce the situation of excessive local pressure, avoid indentation or cracks on the surface of the workpiece, and maintain the integrity and beauty of the workpiece surface. The engagement of the bending teeth and the bending grooves provides additional stability for the bending process. Even when processing materials with relatively large thickness or high hardness, it can maintain a good bending effect and prevent the workpiece from shifting or twisting during bending. The precise design of the bending teeth and the bending grooves reduces the adjustment time and trial-and-error times during the processing, speeds up the bending speed, and improves the overall processing efficiency. By replacing the bending component, different shapes and sizes of bending teeth and bending grooves can be set on the bending component, which can flexibly meet the bending requirements of workpieces with different complexities and shapes, enhancing the processing ability and application range of the equipment.

[0015] Furthermore, the bottom of the spring is welded to the fixing bolt, and the fixing bolt is installed on the upper template and the lower template.

[0016] The spring is fixed to the bolt by welding, and then the bolt is installed on the template, ensuring the stability of the spring during the bending process, avoiding spring displacement caused by vibration or impact, and guaranteeing the stability and consistency of the processing. As the connection point between the spring and the template, the fixing bolt can ensure the accurate transmission of the bending force, reduce the loss of force, and make the bending action more precise and controllable. Using bolts to fix the spring and the template makes the adjustment and maintenance of the equipment simpler and faster. When it is necessary to replace springs of different strengths or adjust the spring position, simply loosen the bolt to easily complete the operation without a complex disassembly and assembly process.

[0017] The utility model has the following beneficial effects:

[0018] 1. The setting of multiple lower die bending parts, in cooperation with springs of different lengths, can achieve precise bending of specific areas of the workpiece, ensuring that each bending part can reach the designed bending angle and position accuracy. And because the spring lengths are different, the time sequence of contact between the upper die bending part and the lower die bending part is also different, avoiding synchronous processing of the workpiece and preventing the phenomenon of workpiece fracture during the bending process;

[0019] 2. The upper die bending part and the punch fixing bending part are connected to the upper template through springs, providing stable supporting force. Even when encountering changes in material hardness or uneven thickness during the processing, a good bending effect can be maintained, preventing the workpiece from shifting or deforming;

[0020] 3. The bending teeth on the upper die bending part and the bending protrusions on the lower die bending part can be set in different shapes according to requirements, and the workpiece can be bent according to requirements. Description of the Drawings

Specific Embodiments

[0025] The following further details the utility model in conjunction with the drawings and specific preferred embodiments.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the parts, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example and do not limit the protection scope of the present utility model.

[0027] Referring to Figure 1 and Figure 2 it can be seen that for a template segmented bending device, the upper template 1 and the lower template 4 are arranged opposite to each other, and the upper template 1 is located directly above the lower template 4, forming the basic framework of the bending device. Two upper die bending parts 13 are provided on the upper template 1, and bending teeth 131 are provided at the bottom of the upper die bending parts 13. A total of five lower die bending parts 41 are installed in the lower template 4. Bending protrusions 411 are provided at the top of the lower die bending parts 41, and bending grooves matching the bending teeth 131 are formed between adjacent bending protrusions 411. The bottom of the lower die bending parts 41 is installed on the fixing bolts 42 of the lower template 4 through springs 11. The upper die bending parts 13 and the stripping bending parts 3 are installed on the upper template 1 through springs 11. The punch fixing bending parts 2 are welded on the upper template 1. The stripping bending parts 13 are installed between the upper die bending parts 13 for assisting in the demolding of the workpiece. The lifting and supporting parts are installed in the lower template for supporting and positioning the workpiece during the bending process. Lifting and supporting parts 5 are installed outside the lower die bending parts 41.

[0028] In one embodiment, the upper template 1 and the lower template 4 are correctly aligned and arranged opposite to each other, and the upper template 1 should be located directly above the lower template 4. This is the basic framework of the bending device. Then, five lower die bending parts 41 are installed in the lower template 4. The bottom of each lower die bending part 41 needs to be fixed on the fixing bolt 42 of the lower template 4 through a spring 11, ensuring that the elasticity of the spring can provide appropriate supporting force. Check the top of the lower die bending part 41 to ensure that the bending protrusions 411 of each part are intact, and the bending grooves formed between adjacent bending protrusions match the bending teeth 131 of the upper die bending part 13. On the upper template 1, two upper die bending parts 13 are installed, ensuring that the bottom bending teeth 131 thereof are aligned with the bending grooves of the lower die bending parts 41. The upper die bending parts 13 are fixed on the upper template 1 through springs 11, ensuring that the elasticity of the springs can achieve precise control of the bending force. A blanking bending part 3 is installed between the upper die bending parts 13 and is fixed on the upper template 1 through a spring 11. The blanking bending part 3 is used to assist in the demolding of the workpiece. The punch fixing bending part 2 should be directly welded to the upper template 1 to ensure its stability. Finally, a lifting and supporting part 5 is installed in the lower template 4, ensuring that the spring 11 between it and the lower template 4 can provide sufficient supporting force to accurately support and position the workpiece during the bending process;

[0029] Place the workpiece to be bent on the lifting and supporting part 5, ensuring that the part of the workpiece to be bent is aligned with the matching position of the bending protrusions 411 and the bending teeth 131. Operate the bending device, the upper template 1 moves downward, and the upper die bending part 13 cooperates with the lower die bending part 41. By the engagement of the bending teeth 131 and the bending protrusions 411, an accurate bending force is applied to the workpiece to achieve bending processing. After bending is completed, the upper template 1 rises, and the blanking bending part 3 assists the workpiece to be removed from the bending parts, and then safely take out the workpiece that has completed bending.

[0030] Referring to Figure 3 , it can be seen that springs 11 are installed at the bottoms of the lower die bending parts 41 on the lower template 4, and the springs 11 have multiple different lengths. The spring 11 at the bottom of the lower die bending part 41 at the center is the longest. The corresponding blanking bending part 3 is also provided with a spring. Springs 11 of the same length are installed at the bottoms of the upper die bending parts 411 on both sides of the blanking bending part 3.

[0031] In one embodiment, the length of the spring 11 at the bottom of the lower die bending part 41 at the center position of the lower template 4 is 7 cm, the lengths of the springs 11 on both sides of the 7 cm spring 11 are 5 cm and 3 cm respectively, the length of the spring 11 at the bottom of the blanking bending part 3 is 7 cm, and the length of the spring 11 at the bottom of the upper die bending part 13 is 5 cm;

[0032] During use, place the workpiece to be bent on the lifting and supporting parts on the lower template 4, ensuring that the bending line of the workpiece aligns with the position of the bending protrusion 411 of the lower die bending part 41. As the upper template 1 moves downward, the first part to contact the workpiece is the lower die bending part 41 supported by the spring 11 with a length of 7 cm. The bending teeth 131 on the stripping and bending part 3 and the upper die bending part 13 cooperate with the bending protrusion 411 on the lower die bending part 41 to bend the workpiece. When the upper template 1 continues to descend, the spring 11 with a length of 5 cm starts to compress, applying a greater force to further deepen the bending degree of the workpiece. At this time, the bending of the workpiece has entered the main forming stage. When the upper template 1 is further pressed down to the lowest point, the bending groove formed by the bending teeth 131 and the bending protrusion 411 contacts, completing the bending process of the workpiece. After the bending is completed, the upper template 1 rises, and the stripping and bending part 3 is driven by the 7-cm spring 11 to separate from the workpiece, avoiding damage to the workpiece during the demolding process.

[0033] Through this graded spring 11 length design, the bending device can bend different parts of the workpiece at different times, reducing material stress concentration, improving the bending quality and production efficiency of the workpiece. This design is particularly suitable for bending processing of complex shapes or sensitive materials, effectively avoiding problems such as fracture or deformation.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept scope of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
