Embodiment 1

[0036] refer to figure 1, is a press forming machine for transformer oil tank production disclosed by the present invention, comprising a frame 1, the top beam of the frame 1 is fixedly connected with a plurality of vertically arranged oil cylinders 2 by bolts, and the piston rods of the oil cylinders 2 are detachably fixedly connected with horizontal The set upper mold base 8, the side of the upper mold base 8 facing away from the oil cylinder 2 is detachably fixedly connected with the upper mold 3, and the frame 1 is detachably connected with the lower mold 4 meshing with the upper mold 3, which is detachably fixedly connected in this embodiment They are all connected by bolts, which are easy to disassemble and stable in connection. A hoisting piece 5 is welded at the center of the top beam of the frame 1 facing the upper mold base 8, and a first hook 6 for cooperating with the hoisting piece 5 is welded at the center of the upper mold base 8, and the upper mold base 8 is al...

Embodiment 2

[0041] refer to Figure 4 , is a press forming machine for transformer oil tank production disclosed by the present invention, the structure is roughly the same as that of Embodiment 1, the difference is that in this embodiment, the lower mold 4 is provided with three sets of bending gaps of different specifications, and the lower mold 4 The mounting piece is integrally connected, and the mounting piece is provided with a waist-shaped hole. The length direction of the waist-shaped hole is perpendicular to the length direction of the lower mold 4. The connection between the lower mold 4 and the frame 1 is realized by bolts passing through the waist-shaped hole, and can be adjusted. The installation position of the lower mold 4 on the frame 1 makes the bending gaps of different specifications on the lower mold 4 move to the position opposite to the upper mold 3; in addition, the fourth hook 10 welded by the lower mold 4 (not shown in the figure) It can cooperate with the driving...

Abstract

The invention relates to the technical field of bending machine pressing dies, in particular to a forming press for transformer oil tank production. The forming press comprises a machine frame, a plurality of vertically arranged oil cylinders are fixedly connected to the bottom of a top beam of the machine frame, piston rods of the oil cylinders are detachably and fixedly connected with a horizontally arranged upper die, the machine frame is detachably connected with a lower die meshed with the upper die, the machine frame is fixedly connected with a hoisting piece, a first hook matched with the hoisting piece is arranged in the middle of the upper die, and second hooks are fixedly connected to the two ends of an upper die base in the length direction of the upper die base. The forming press has the effect that dies are convenient to replace and maintain.

Description

technical field [0001] The invention relates to the technical field of pressing dies for bending machines, in particular to a pressing machine for producing transformer oil tanks. Background technique [0002] The corrugated sheet forming machine is a special equipment for producing corrugated oil tanks of transformers. The corrugated oil tank forming machine includes: uncoiling, host, hydraulic system, electric control system, etc. The main engine is composed of mechanism devices such as material guide, material feeding, limit, material pushing, front pressing, ejecting, rear pressing, shearing and receiving. [0003] The Chinese invention patent with the authorized notification number CN105710655B discloses a corrugated sheet forming machine, including a machine base, which is provided with a cutting mechanism, a front mold mechanism, an upper mold mechanism and a rear mold mechanism in sequence from front to back, and the rear mold mechanism It is slidably arranged on t...
