Problems solved by technology

This scheme has a good effect on the side wall shape correction, but there are obvious rough correction marks on the bottom surface of the box-shaped bottom and the rounded corners. The chamfers are measured with a measuring card, and there are large tolerances and uneven changes; aluminum alloy The natural aging time is fast, and the optimal shape correction time is short. This solution consumes a lot of time for the bottom shape of the box shape, and often cannot reach the best state
[0003] Aiming at the unsatisfactory bulging effect on the end face of the inner wall of the box-shaped part and the rounded corner by the traditional correction die, the invention discloses a split-type shape-calibrating tool for the inner welded box-shaped part

Embodiment 1

[0026] A kind of split-type shape-correcting frock for inner weld box-shaped parts of this embodiment, such as figure 1 and figure 2 As shown, it includes a bulging cone shaft 3, and at least two split bulging parts 1 are slidably combined around the bulging cone shaft 3, and one side of the split bulging part 1 and the bulging cone shaft 3 are combined A tapered groove is provided on the conical surface corresponding to the bulging cone shaft 3, and the bulging cone shaft 3 pushes the split bulging part 1 to expand outward for bulging by moving axially; the adjacent split bulging part 1 are connected by guide connectors.

[0027] The side of the split bulging part 1 close to the bulging cone shaft 3 is the pressure side, the top surface of the split bulging part 1 and the side close to the inner wall of the box-shaped part are the bulging side, and the split bulging part 1 The edge of the top surface of the box is provided with a bulging fillet for bulging the inner fillet...

Embodiment 2

[0030] This embodiment is further optimized on the basis of embodiment 1, such as Figure 1-Figure 3 As shown, the bottom side of the bulging cone shaft 3 is provided with a limiting member 2 extending into the tapered groove on the side of the split bulging part 1 .

[0031] The width of the stopper 2 is between the maximum width and the minimum width of the tapered groove, and the stopper 2 extends into the tapered groove on the split bulging member 1. When the bulging cone shaft 3 does not move upward, this When the stopper 2 is located at the bottom of the tapered groove; when the bulging cone shaft 3 moves upward under the action of an external force, the stopper 2 slides upward along the tapered groove with the bulging cone shaft 3 until the stopper 2 slides To the position where the width of the tapered groove is smaller than the width of the stopper 2, at this time the stopper 2 cannot continue to slide due to the restriction of the tapered groove, so that the bulging ...

Embodiment 3

[0035] This embodiment is further optimized on the basis of above-mentioned embodiment 1 or 2, such as figure 1 and figure 2 As shown, four split bulging parts 1 are slidably assembled around the bulging cone shaft 3 , and the guide connection surfaces of adjacent split bulging parts 1 are connected by guide pins 4 .

[0036] The four split bulging parts 1 are the first bulging part 01, the second bulging part 02, the third bulging part 03, the fourth bulging part 04, the first bulging part 01, the second bulging part 02. The third bulging piece 03 and the fourth bulging piece 04 are square column hollow structures. The first bulging piece 01, the second bulging piece 02, the third bulging piece 03 and the fourth bulging piece 04 are close to The two mutually perpendicular end surfaces of the inner wall of the box-shaped member are bulging surfaces, and the first bulging member 01, the second bulging member 02, the third bulging member 03, and the fourth bulging member 04 ar...

Abstract

The invention discloses a split type shape correcting tool for an inner weld joint box-shaped part. The split type shape correcting tool comprises a bulging conical shaft, at least two split bulging parts are spliced to the periphery of the bulging conical shaft in a sliding mode, conical grooves are formed in sides, spliced with the bulging conical shaft, of the split bulging parts and correspondto the conical face of the bulging conical shaft, and the bulging conical shaft pushes the split bulging parts to expand outwards for bulging through axial movement; and every two adjacent split bulging parts are connected through a guide connecting piece. The split type shape correcting tool can synchronously and efficiently perform synchronous bulging calibration on the inner side wall, the inner side top end face and the fillet of the box-shaped part, greatly improves the appearance calibration efficiency and the calibration quality of the box-shaped part, and effectively shortens the manufacturing period.

Description

technical field [0001] The invention belongs to the technical field of shape-correcting tooling for sheet metal parts, and in particular relates to a split-type shape-correcting tooling for inner welded box-shaped parts. Background technique [0002] For large-depth box-shaped parts that exceed the limit of deep-drawing, generally the bottom of the box-shaped box with a suitable depth is manufactured by deep-drawing, and then made by welding the side walls. Welding from the inside of the box-shaped part and the weld seam on the inner wall can ensure the aerodynamic appearance and visual beauty of the part to the greatest extent. However, due to the large amount of deformation of aluminum alloy welding and the characteristics of fast natural aging, it will bring difficulties to the follow-up work of shape correction. The existing solution is to correct the welded side wall through the correction mold, and the box-shaped bottom adopts the correction mold of 1 / 4~1 / 3 bottom shap...
