Example Embodiment

[0015] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0016] Such as figure 2 As shown, the one-shot round forming process of the present invention is formed by a single set of molds at one time, and the blanked sheet 5 is placed horizontally between the upper die 2 and the core rod 3 (see figure 2 a), the upper die 2 goes down to bend the two edges of the sheet 5 into a vertical state. When the upper die 2 is in place, the cavity between the upper die 2 and the core rod 3 forms the upper semicircle of the workpiece 1 (see figure 2 b); Then the upper die 2 and the core rod 3 go down at the same time, the two edges of the sheet 5 touch the arc surface of the lower die 4, are gradually closed and finally formed in the cavity between the lower die 4 and the core rod 3 Out the lower semicircle of workpiece 1 (see figure 2 c). At this time, the ring workpiece 1 is reshaped by adjusting the pressure of the main cylinder...

Abstract

The invention discloses a process and a die for one-time round-bending and molding. The die comprises an upper female die, a core rod, a lower female die, a feeding mechanism, a material pressing mechanism and a discharging mechanism, wherein the upper female die is fixed to an upper template and slides up and down on a die set through a guide sleeve which is matched with a vertical guide column; the lower female die is fixed to a lower template; the core rod is fixed to a vertical lateral sliding plate capable of moving up and down and is positioned between the upper female die and the lower female die; and a horizontal guide column is provided with a horizontal lateral sliding plate, and the horizontal lateral sliding plate is connected with a front handle through a pull rod. Compared with the conventional molding process, the process for one-time round-bending and molding has the advantages that the procedures are reduced by a half, the structure is compact and reasonable, equipment, manpower and sites are greatly reduced, the energy resources are saved, the cost is low, the molding effect of large rings is good, the quality performance is stable, and the process and the die have higher cost performance and high economic benefit.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a one-time round bending forming process and mold for plates. Background technique [0002] Current cylindrical automotive heat shields (see figure 1 ) is usually formed by stamping steel plate with a thickness of 1mm and a diameter of about φ110mm; since the diameter of the forming ring is greater than 40mm, it is usually formed by two processes at present, that is, it is first bent into a wave shape, then bent into a circle, and finally plastic surgery. This three-step molding method has many processes, long processing route, and high mold processing and manufacturing costs. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned three-step forming method in the production of large-diameter cylindrical parts, the applicant provides an easy-to-operate one-time round-bending forming process and mold, and completes the manufacture of large-diamete...
