Problems solved by technology

[0007] 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 container roof hydraulic forming method. The hydraulic press used in the present invention is a special machine designed for the container roof structure. The overall price of this model 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

[0049] combine figure 1 and image 3 , a special hydraulic press for container roofs in this embodiment, comprising an upper box body 11, an upper slider 12, an upper mold 15, an upper main cylinder 16, a lower box body 21, a lower main cylinder 23, a lower slider 24 and a 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.

[0050] 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 link 173 ...

Embodiment 2

[0055] combine Figure 5 , Image 6 , Figure 7 and Figure 8 , a special hydraulic press for container roofs in this embodiment is basically the same as in Embodiment 1, except that the design of the upper die 15, the lower die 27 and the blank holder 26 is further optimized in this embodiment, specifically: the upper die is set 15 is 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 mold base 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.

[0056] It is worth noting that, in the initial design of the hydraulic press, the inventor did ...

Embodiment 3

[0058] combine Figure 9 , a special hydraulic press for container roofs in this embodiment is basically the same as in Embodiment 2, the difference is that in this embodiment, a back gauge device is provided on one side of the lower box body 21 in the direction of plate movement, and the back gauge device The traction sheet moves horizontally in one direction. The back gauge device includes a motor 31, a rear support plate 32, a screw rod 33, a sliding seat 341, a finger 346, a front support plate 36 and a sprocket 37, and the front support plate 36 is connected to the lower box 21 through a screw 361 , said screw rod 33 is provided with two, and two screw rods 33 are straddled in parallel between the front support plate 36 and the rear support plate 32, and one end of one of the screw rods 33 is connected with the motor 31, and the other end is provided with a chain Wheel 37; Another screw mandrel 33 one ends also are provided with sprocket wheel 37, and drive chain is set ...

Abstract

The invention belongs to the technical field of container top plate manufacturing and discloses a container top plate hydraulic-forming method. The method includes steps: firstly, a to-be-formed steelplate is put on a side pressing ring on a workbench; secondly, a piston of an upper main oil cylinder moves horizontally to drive a main swing rod to rotate around a fulcrum axially while a cross beam drives an auxiliary swing rod to rotate around a fulcrum axially, two perpendicular connecting rods are driven to move downwards vertically, and then an upper mould moves downwards to tightly pressthe to-be-formed steel plate; thirdly, a lower main oil cylinder drives a lower mould to move upwards vertically to realize one-time forming of bind waves on the to-be-formed steel plate; fourthly, amotor drives screw rods to rotate, a slide seat sleeving the two screw rods moves horizontally, and a retainer drives the steel plate to move to perform next blind wave forming operation. A special machine designed aiming at the container top plate structure is adopted for the forming process, equipment purchase cost is sharply reduced, and economic burden of small-and medium-sized container top plate production enterprises is relieved.

Description

technical field [0001] The invention relates to the technical field of container roof manufacturing, and more specifically, relates to a container roof hydroforming method. 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 10 A plurality of blind waves 41 are arranged on the container roof 4, and the structure of the blind waves 41 protrudes upward from the container roof 4 and is closed around. The blind wave 41 of the container roof 4 is integrally formed. [0003] 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 proc...
