New description: [New technical field] The creation department provides a kind of creaseless bending lower die structure, and the elastic element set by the lower body structure body should be decorated with folding bed. The resistance of her components makes the two pairs of folded edges of the bent piece have no age, and at the same time, the wear of the lower mold structure body and the subsequent processing steps can be reduced, which not only improves the production efficiency, but also ensures the folding of the material. Perfect shape to further extend the life of the lower die. [Prior Art] Press, folding bed processing is a processing method often used by manufacturers. Please refer to the first figure. The folding bed processing is mainly done by _下模县_上上- difficult to view, in the structure of the miscellaneous 11 on the use of the placement - plastic (four), and above the concave and concave portion of the mold knot, a mechanical stamping of the folding knife 12 'the folding knife 12 can move up and down the movement of the stamping, after the folding processing of the bending member S The bending point i is the concave and convex shape of the mold, so that the process can prevent the two bending pieces of the bending piece from forming a point or a line of indentation at the top end of the mold structure; and removing the bending piece after processing S, repeating the subsequent repeated stamping process, in which it is necessary to re-move the position of the valve pad 13 so that the main purpose of the method is to buffer and remove the folding bed processing by the plastic winch 13 Gu, of course, the above-mentioned jade process must rely on the operator's familiarity and skill, in which the safety and production efficiency are more often caused by the operator; therefore, how to eliminate the above-mentioned defects and provide a Design of crease bending under the die structure At the same time, for the improvement of the mold structure of the above-mentioned processing, through the use of the elastic element provided by the body of the mold structure M314082, when applied to the folding bed construction, the two of the bending parts are obtained by the cushioning of the elastic member. There is no indentation on the folded edge, and at the same time, the wear of the lower mold structure body and the subsequent processing steps can be reduced, which not only improves the production efficiency, but also ensures the perfect shape of the bent part, thereby prolonging the service life of the lower mold. This is the technical difficulty point that the creators of this case want to solve. [New content] # This creation provides a crease-free bending die structure, the main feature of which is that at least the corresponding groove is formed at the fold of the lower die structure body and the folding knife. The elastic element and the lower mold structure may be stacked and arranged in different widths, and the f-fold shape of the folding edge of the folding knife is geometrically curved, and the impurity shape (four) hardness is slightly smaller than the lower portion. The material of the mold structure body is used when the folding bed is applied, and the two pairs of folded edges of the bent piece are not indented by the cushioning of the elastic member in the groove, and at the same time, the lower portion can be reduced. The wear of the mold structure and the subsequent processing steps not only improve the production efficiency, but also ensure the perfect shape of the folding piece, and further extend the service life of the lower mold. [Embodiment] In order to make it easy for your examiner to understand the other features and advantages of this creation and the effects achieved by it, _ more ships, miscellaneous § & customs, the details are as follows: · see first As shown in the second figure, the present invention provides a creaseless bending lower mold structure, which mainly comprises at least one or more lower mold structure bodies 2, and the lower mold structure body 2 has a width that is not-shaped. The stacking of the T-die structure body 2 can be matched with the bending forming forming width M314082 degrees, and at least one corresponding groove 2 is provided at the fold of the contact edge of the lower mold structure body 2 and the folding knife 12. The elastic member 200 is disposed in the groove 20, and the curved shape of the contact edge of the folding knife 12 is geometrically curved, and the hardness of the elastic member 200 is slightly smaller than that of the lower mold structure 2. The material of the elastic member 200 can be a plastic steel (POM) or a high elastic hard rubber material, and the elastic member 200 can be received in the groove 2 of the connecting end body 2 connected to the connecting end thereof. In the crucible, not only the lower mold structure can be reinforced by the insertion of the elastic member 200 The body 2 is closely connected to each other, which can eliminate the pressure points or indentations generated when the end joints are folded, which is more convenient to replace than the whole lower mold structure body 2 and effectively reduce the time of folding press The generated noise; please refer to the fourth and fifth figures. In the figure, the bending member S is subjected to the bending at the tangential end a of the curved surface 21 of the geometry of the lower mold structure body 2 during the folding process. The reflexing force P′ generated after the folding of the piece 3 is performed. When the folding bed is processed, the tangent end of the lower mold structure body 2 secures the reverse flap of the bending member 8 and simultaneously applies a reflex The force p, and the material hardness of the lower mold structure body 2 is greater than the material of the folded odd part S, so that the bending part of the bending part is concave or a concave line, and the body of the lower mold structure is created. An elastic element 2〇() is inserted into the groove of the 2, and the elastic element 2〇〇 extends outwardly to expose to cross-cut ΦΒ'. When the bending member 3 rides, the bending member is folded after the folding The reflexing force P just touches the cross-section B of the elastic member 200, and the elastic element 2 回复() recovers-rebound force p, which counteracts the reflexing force The surface of the bending member S is formed into a non-indented riding surface, and is pressed by the adhesive of the creative elastic τ ο 2 2GG to reduce the structure of the crease-free manufacturing process; The detailed description is for the specific description of one of the possible embodiments of the present invention, but the embodiment is not intended to limit the scope of the county, and any equivalent implementation or change without departing from the spirit of the art should be included in the case. Patented fine towel. M314082 In order to make this creation more progressive and practical, a comparative analysis is used as follows: • Lack of use 1. In order to meet different folding presses, plastic enamels of different thicknesses must be prepared. 2. The plastic pad placed on the mold must be replaced or replaced at any time. 3. The processing procedure must rely on the operator's familiarity and skill, and is not in line with the economic efficiency of mass production. Advantages of the creation 1. By the arrangement of the elastic element, the action of shifting the buffer plastic pad during the folding bed processing is removed. 2. Effectively protect the safety of operators and avoid accidental injuries. 3. The combination of different thickness bends can be combined to reduce the mass production time, making the finished workpiece competitive in the industry. In summary, 'this creation has achieved the desired effect under the previous technical structure, and it is not easy for people who are familiar with the art to think about it. Moreover, this creation has not been disclosed before the application. The progressiveness and practicability have already met the requirements for the application of the new patent, and the application has been filed according to law. Please ask your bureau to approve the application for this new type of patent to encourage creation.
