Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem of high procurement cost of existing container roof blind wave forming equipment, and provide a low-cost container roof hydraulic forming system. The present invention is a special machine designed for the container roof structure. The overall price of the type is only tens of thousands of yuan. Compared with the traditional bending machine and a complete set of mold pressing process, it greatly reduces the cost of equipment procurement and reduces the economic burden of small and medium-sized container roof manufacturers.

Embodiment 1

[0037] combine figure 1 and image 3 , a low-cost container roof hydroforming system of the present embodiment includes an upper box body 11, an upper slider 12, an upper mold 15, an upper main oil cylinder 16, a lower box body 21, a lower main oil cylinder 23, a lower slider 24 and Lower mold 27. Described upper master oil cylinder 16 is arranged on upper box body 11 tops, and upper slide block 12 is arranged on upper box body 11 bottoms, and upper mold base 14 is arranged at the bottom of upper slide block 12, and upper mold base 15 is fixed on upper mold base 14.

[0038] A drive unit is arranged between the upper master oil cylinder 16 and the upper slider 12, combined with figure 2, the drive unit includes a main swing link 171, a beam 172, a secondary swing link 173 and a vertical link 174, one end of the beam 172 is connected to the main swing link 171, and the other end is connected to the secondary swing link 173. Both the swing link 171 and the auxiliary swing l...

Embodiment 2

[0043] combine Figure 5 , Figure 6 , Figure 7 and Figure 8 , a low-cost container roof hydroforming system of this embodiment is basically the same as that of Embodiment 1, the difference being that this embodiment further optimizes the design of the upper die 15, the lower die 27 and the blank holder 26, specifically: The upper die 15 is set as a die, and threaded holes are set around the die cavity, and the die is inserted into the threaded holes by bolts to be connected with the upper die holder 14 at the bottom of the upper slide block 12 . The lower die 27 is a convex die, and threaded holes are arranged along the length direction of the lower die 27, and the lower die 27 is inserted into the threaded holes by bolts to be connected with the lower block 24. The upper die 15, the blank holder 26 and the lower die 27 are all designed with a large arc surface along the length direction.

[0044] It is worth noting that, in the initial design of the hydraulic press, th...

Embodiment 3

[0046] A low-cost container roof hydroforming system in this embodiment is basically the same as in Embodiment 2, except that the thickness L1 at the highest point of the large arc surface in the length direction of the blank holder 26 in this embodiment is the same as the thickness at the lowest point. The difference in L2 is 14.2mm. The difference L3 between the thickness at the highest point and the lowest point of the small arc surface of the blank holder 26 along the width direction is 3.5 mm.

Abstract

The invention discloses a low-cost container top plate hydraulic forming system and belongs to the field of hydraulic forming. The system comprises an upper box body, upper sliding blocks, upper molds, an upper main oil cylinder, a lower box body, lower main oil cylinders, lower sliding blocks and lower molds. The upper main oil cylinder is arranged at the upper part of the upper box body, and theupper sliding blocks are arranged at the lower part of the upper box body; the upper molds are fixed at the bottom of the upper sliding blocks, and a driving unit is arranged between the upper main oil cylinder and the upper sliding blocks; the upper main oil cylinder drives the upper sliding blocks to move in a vertical direction through the driving unit; and the lower sliding blocks are arranged in the lower box body, the lower portions of the lower sliding blocks are connected with the lower main oil cylinders, the upper portions of the lower sliding blocks are connected with the lower molds, and the lower main oil cylinders drive the lower sliding blocks to move in the vertical direction. The low-cost container top plate hydraulic forming system relates to a special machine designed for a container top plate structure, the cost of equipment purchasing is greatly reduced, and the economic burden of a small-and-medium-sized container top plate production enterprise is reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, and more specifically relates to a low-cost container roof hydroforming system. Background technique [0002] As a general means of transportation, containers have played a great role in the existing logistics industry. At present, the commonly used container roof generally adopts the blind wave roof, and the specific structure can be found in Figure 9 A plurality of blind waves 31 are arranged on the container roof 3, and the structure of the blind waves 31 protrudes upward from the container roof 3 and is closed around. The blind wave 31 of the container roof 3 is integrally formed. The hydraulic press is an important forming equipment. The motor drives the hydraulic pump to generate high-pressure liquid, and the hydraulic cylinder generates linear motion to work. Due to the wide adaptability of hydraulic machining, it is widely used in metal and non-metal forming processing. At p...
