specific Embodiment approach 1

[0039] Specific implementation mode one: combine Figure 1~3 , Figure 7~9 This embodiment will be described. The device of this embodiment includes a punch 1 , a blank 2 , a base 3 , an insert 4 , an inner sleeve 5 , and an outer sleeve 6 . The base 3 is placed on the press table, the inner sleeve 5 is placed on the base 3, the insert 4 is put into the groove 5-1 on the side of the inner sleeve 5, and the outer sleeve 6 is placed on the base 3, The outside of the combination of the insert 4 and the inner sleeve 5 .

specific Embodiment approach 2

[0040] Specific implementation mode two: combination figure 1 , figure 2 , Figure 4 , Figure 7 , Figure 8 and Figure 10 Describe this embodiment. This embodiment is to form plates with different thicknesses in a single pass. The shape of the formed plate can be controlled by replacing the insert 4 and changing the slot hole 4-1. The specific forming dimensions are based on the specifications of the plate in actual production. And the size of the module is adjusted, the height of each slot hole 4-1 is different, in the same time, the length of the plate formed by the higher cavity is shorter, and the formed part is Figure 10 , and other connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0041] Specific implementation mode three: combination figure 1 , figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 11 Describe this embodiment. This embodiment is to form a plate with any curvature. Start the press to load and shape the punch 1, and the compressed deformed blank 2 flows into the cavity between the ribs 7 in the insert 4 in the radial direction, and the formed part As shown in Figure 11, the metal is in a flowing state during the forming process, and the formed part does not have a rebound phenomenon, which significantly improves the shapeability, and other connection relationships are the same as in the first embodiment.

Abstract

The device and method for batch modularized lateral extrusion of boards relate to a device and method for high-efficiency batch lateral extrusion of boards, which can solve the long-standing problems of low production efficiency, cumbersome procedures, and complex device structures in the batch manufacturing process of boards Wait for the bottleneck. Device: the inner sleeve 5 is placed on the base 3, and the blank 2 and the punch 1 are put into the inside sequentially, the insert 4 is placed between the groove 5-1 of the inner sleeve 5 and the base 3, and the outer sleeve 6 is placed The base 3, the insert 4, and the outer side of the inner sleeve 5. Method: According to the actual requirements of the formed product, the structure of the corresponding insert 4 and the rib plate 7 is replaced by using the idea of ​​modularization. During the extrusion process, the punch 1 is loaded downward, and the compressed deformed blank 2 flows into the insert 4 sequentially along the radial direction. The groove hole 4‑1 can be customized in batches with various specifications such as different shapes, sizes and quantities, and at the same time can realize fine-grain modification of extruded plates. The invention is suitable for extrusion molding of plates in batches.

Description

technical field [0001] The invention relates to a processing and forming method for metal plates, in particular to a batch modular lateral extrusion forming method for plates, which belongs to the technical field of extrusion forming. Background technique [0002] Sheet metal components are one of the main ways to achieve lightweight materials and structures. They are widely used in many fields such as aerospace and automobile manufacturing, and the demand is increasing year by year. At present, the main methods for large-scale and efficient processing and manufacturing of sheet metal include cold continuous rolling, continuous casting and continuous rolling, and cast-rolling. [0003] Continuous cold rolling refers to the continuous cold deformation of the hot-rolled steel plate in the continuous rolling mill after pickling to remove scale, and the strength and hardness of the plate are improved through degreasing, annealing and other steps. Formed parts are obtained throu...
