figure 1 The structure shown is a common battery cavity. We noticed that a convex hull is formed at A, which has been formed before bending. However, the subsequent bending operation will cause the shape of the convex hull to change. changes, resulting in an undesired increase in convex hull height, which affects product yield

Embodiment Construction
[0015] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0016] see Figure 2 to Figure 4 , the bending die core with the function of adjusting the height of the convex hull of the battery cavity of the present invention is formed with a bending structure for bending the battery cavity and adjusting the height of the convex hull 1, and the bending structure is a step-shaped gap.
[0017] In order to understand the present invention more vividly and fully, specifically, as figure 2 As shown, the side profile of the bending structure includes: a limit line 201 that is in close contact with the convex hull 1 of the battery cavity during the bending process, and the limit line 201 is parallel to the lower edge line 204 of the bending die core 2 and the two pass through The first circular arc 202 is connected, and the limit line 201 is connected to the side edge line 205 of the bending die core 2 ...

The invention discloses a bending die core with a battery cavity convex hull height adjusting function. The bending die core is characterized in that the die core is provided with a bending structure for bending a battery cavity and adjusting the height of a convex hull, the bending structure is a step-shaped gap, a profile contour line of the bending structure comprises a limit straight line which is tightly glued with the battery cavity convex hull in the process of bending, the limit straight line and the lower edge line of the bending die core are in parallel with each other and are connected with each other by a first arc, and the limit straight line is connected with the side edge of the bending die core by a second arc. The ending die core with the battery cavity convex hull height adjusting function can adjust and control the height of the convex hull in the process of bending, so that the yield of battery cavity products can be preferably improved, and the bending die core is simple in structure, lower in cost and convenient to operate.
Description
technical field [0001] The invention relates to a bending mold core, in particular to a bending mold core with the function of adjusting the height of a convex hull of a battery cavity. Background technique [0002] The battery cavity is the part used to accommodate the battery in the mobile phone, and its size requires high precision. The forming process includes: stamping, flanging, bending, etc. figure 1 The structure shown is a common battery cavity. We noticed that a convex hull is formed at A, which has been formed before bending. However, the subsequent bending operation will cause the shape of the convex hull to change. Changes, resulting in an undesired increase in the convex height, which affects product yield. Currently, this technical defect has not been resolved. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to overcome the deficiencies of the prior art and provide a bending die...
