Problems solved by technology

[0005] Compared with the prior art, the present invention adopts the above-mentioned technical scheme, positions and bends the bending mold, and can complete the work that can only be completed by the original two processes of line drawing and bending in one process, and overcomes the cumbersome process and high labor cost. Many defects; in addition, using flanging mold positioning for flanging instead of line drawing positioning has high precision and stable quality

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0020] like Figure 1-6 As shown, the bending mold for the upper cover of the shielding box includes a male mold 1 and a lower template 6 arranged below the male mold 1. The upper surface of the lower template 6 is sequentially fixed with a backing plate 5, a female mold 4, and a positioning plate 3 from bottom to top. , the cavity formed by the backing plate 5, the female mold 4, and the positioning plate 3 is provided with a ejector 2 that is movably connected with the elastic unloader 8 through the ejector rod 7, and the female mold 4 is provided with an escape groove 4-1 . Before bending, place Figure 9 The workpiece shown is placed on the ejector 2, as Figure 7-8 As shown, driven by the power, the male die 1 moves downwards, pressing the workpiece 9 down for flanging. After the flanging is completed, the male die 1 is retracted, and the ela...

Abstract

The invention relates to a mold, in particular to a shielding box cover folding die. The shielding box cover folding die comprises a male die (1), and a lower die plate (6) arranged below the male die (1). A base plate (5), a female die (4) and a positioning plate (3) are fixed to the upper surface of the lower die plate (6) from bottom to top in sequence. An ejecting device (2) movably connected with an elastic unloader (8) through an ejecting rod (7) is arranged in a cavity formed by the base plate (5), the female die (4) and the positioning plate (3). An avoiding groove (4-1) is formed in the female die (4). Compared with the prior art, by the adoption of the technical scheme, a bending die can be located and bent; the work of two original processes of line drawing and bending can be finished through one process; defects of complicated process, high labor cost and the like are overcome; and in addition, flanging die positioning is used for flanging instead of line drawing positioning, thereby being high in precision, and stable in quality.

Description

technical field [0001] The invention relates to a mold, in particular to a shielding box cover folding mold. Background technique [0002] like Figure 12 As shown, the shield cover is a thin-walled shell part with a relatively complex structure, and the requirements for the consistency of the matching mounting holes, angles, and flange heights are relatively strict. At present, when processing the shield and closing the cover, it usually goes through the following procedures: blanking-drawing-bending-proofreading-bending-correction-drilling. Because it is necessary to position the material on the blanking mold first, draw the line after the material is loaded, and then transfer it to the bending mold for two times of bending, and then transfer to the drilling mold for positioning and drilling. Repeated positioning will cause parts processing accuracy The bending position is specified by drawing lines, resulting in large dimensional errors, and the entire process has defect...
