Description

TECHNICAL FIELD

[0001] The utility model relates to a bending die technical field, concretely is a kind of partition misplacement bending die. BACKGROUND

[0002] As shown in Figure 1 There is a workpiece, along the bending angle direction has a right-angle flange and a multi-section flange, that is, two bending structures are distributed in partition mislocation, and the bending angles of the two bending structures are different. Since the right-angle bending and the multi-section flange are distributed in partition mislocation, the workpiece needs to use two molds for two bending actions during traditional forming. The two bending actions can easily cause the reference of the two bending structures to deviate, and the operation efficiency is low. When bending twice, if the multi-section flange is formed first and the right-angle flange is formed later, there will be a crease at the junction of the multi-section flange after the right-angle flange is formed, which reduces the mechanical properties of the workpiece and makes the appearance poor. If the right-angle flange is formed first and the multi-section flange is formed later, the middle section of the flange (flange A) will tilt towards the side close to the horizontal plane or vertical plane or have wrinkles in that area due to the bending die. If it tilts, it can easily cause the multi-section flange and the right-angle flange to tear at the mislocation surface.

[0003] Therefore, the existing workpiece is prone to reference deviation and has low operation efficiency, poor forming quality, and other problems when bent twice. INVENTION CONTENTS

[0024] This invention utilizes a two-part zoned bending structure on a single bending die to perform zoned and staggered bending of corresponding bending angles on a workpiece, achieving one-time forming with high quality and precision. Specifically, bending assembly one and bending assembly two are used to bend and form the two staggered bending angles respectively. During bending, bending assembly two first contacts the workpiece. As the upper die continues to descend, bending assembly two moves upward relative to bending assembly one. Subsequently, pressure structures one and two act simultaneously to deflect the bending assembly and stretch the spring.

Simultaneously with the completion of the bending action of edge A, pressure structures one and two are aligned with the corresponding action areas, and at this time, the bending body is in a vertical state away from the forming surface of the pressure structure. Therefore, the bending action of edge B is also completed synchronously. Attached Figure Description

[0039] Bending assembly one and bending assembly two simultaneously complete the forming action of the corresponding bending area on the workpiece.

[0040] The upper mold base 10 includes a bending body one and a bending body two. The bending body two slides relative to the bending body one within a certain elevation range, so that the bending body two contacts the workpiece first during the downward movement of the upper mold base 10, and then moves upward after contacting the workpiece.

[0041] The forming upper body 11 includes a bending structure 111 disposed on the bending body 1 and a pressure structure 112 disposed at the bottom of the bending body 2; the bending structure 111 is used to form the folded edge B, and the pressure structure 112 is used to form the folded edge A.

[0042] The forming upper body 2 12 includes a folding structure 2 121 disposed on the bending body 1 and a pressure applying structure 2 122 disposed at the bottom of the bending body 2; the folding structure 2 121 is used to form a right-angle folded edge, and the pressure applying structure 2 122 is used to press down the right-angle horizontal edge of the workpiece.

[0043] The lower body 21 includes a forming structure 221 disposed on the lower mold base 20 and corresponding to the position of the pressure structure 112; the forming structure 221 serves as a lower mold for forming multi-segment folds.

[0044] The second forming body 22 includes a second forming structure 222 disposed on the lower mold base 20 and corresponding to the position of the second pressure structure 122. The second forming structure 222 serves as a lower mold with a right-angle folded edge.

[0045] The first fold structure 111 and the second fold structure 121 both include a mounting groove 30 on one side of the bent body and a fold body 40 at the bottom of the first fold body. The root of the mounting groove 30 is provided with a vertical through hole, and a spring 31 is installed in the vertical through hole. A fixing member 32 is installed on the top of the vertical through hole by bolts. The top of the spring 31 is installed on the fixing member 32 and the bottom is installed on the fold body 40, so that the bent body 40 is pulled tight and fits against the bottom of the first fold body, and rotates relative to the first fold body, for forming the folded edge B and the right-angle folded edge.

[0046] The angled body 40 has a notch on one side corresponding to the pressure-applying structure. The notch is used to form the angle of the workpiece. The notch is used to form the folded edge B and the right-angle folded edge.

[0047] The bottom of the first bending body is provided with an action area that is adapted to the first pressure structure 112 and the second pressure structure 122 on the side near the second bending body.

[0048] A positioning area is provided at the root of the action area, which is used for the rotation of the angled body 40 relative to the bent body 1.

The lower surface of the pressure-applying structure 122 is flush with the bottom of the bending body 2.

[0051] The notch of the angled body 40 simultaneously acts on the upper surface of the corresponding pressure-applying structure.

[0052] In use, the workpiece is placed on the lower die base 20 at the predetermined bending position. The upper die base 20 moves downward, and the second bending body first contacts the workpiece and moves upward relative to the first bending body along the waist-shaped hole 50. When it moves upward to the upper surface of the first pressure structure 112 and adheres to the corresponding corner body 40, the upper surface of the second pressure structure 122 also adheres to the corresponding corner body 40 at the same time. The upper die base 20 continues to move downward, and the first pressure structure 112 gradually forms the folded edge A. When the upper surface of the first pressure structure 112 adheres to the bottom working area of ​​the first bending body, the upper surface of the second pressure structure 122 also simultaneously adheres to the bottom working area of ​​the first bending body. At this time, the side of the notch on the corner body 40 away from the pressure structure is in a vertical state, which will simultaneously form the folded edge B and the right-angled folded edge. Subsequently, the upper die base 10 moves upward, and the corner body 40 rotates and resets under the action of the tension spring 31. At the same time, the second bending body automatically falls back to the initial position.
