The utility model discloses a pipe expanding machine allowing one-time shaping of an expansion port. The pipe expanding machine comprises a pressure apparatus, an upper pressure plate, a push rod, two guide rails, a lower pressure plate, a swelling rod, an upper floating board, a lower floating board, an expanding joint, a crossbeam, a pre-tensioning block, pre-tensioning pressure devices, a base and a through hole, wherein the two guide rails penetrates through the upper pressure plate, the lower pressure plate, the crossbeam and both ends of the base, the upper end of the push rod penetrates through the upper pressure plate and connects to the pressure apparatus, the lower end of the push rod penetrates through the lower pressure plate and connects to the upper floating board, the upper end of the swelling rod connects to the upper floating board, the lower end of the swelling rod penetrates through the lower floating board, the expanding joint is positioned on the lower end of the swelling rod, the pre-tensioning block is fixed on the lower surface of the crossbeam, the pre-tensioning pressure devices are arranged at both ends of the crossbeam, and the through hole is positioned in the crossbeam and right below the expansion joint. The pipe expanding machine is characterized in that the expansion joint is provided with an expansion joint portion, a flaring portion and a flaring sleeve, wherein the lower portion of the flaring portion is connected with the expansion joint portion, and the upper end of the flaring portion is connected with the flaring sleeve. Compared with the prior art, the pipe expanding machine achieves the purpose of one-time shaping of an expansion port, is capable of expanding a plurality of pipes and substantially improves efficiency.

Description

One formation type electric tube expander of a kind of bloated enlarging

Technical field

The utility model relates to a kind of electric tube expander, particularly one formation type electric tube expander of a kind of bloated enlarging.

Background technology

Existing electric tube expander, existing tube expansion technique mostly only are expand tubes, realize the expander form that expands, and also need to increase an equipment, and as electric tube expander or pipe end forming machine, operation is many like this, and efficient is low.

The utility model content

The utility model technical issues that need to address are at above-mentioned the deficiencies in the prior art, and provide a kind of bloated enlarging one formation type electric tube expander.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

One formation type electric tube expander of a kind of bloated enlarging comprises pressure apparatus, top board, catch bar, two guide rails, lower platen, expander roll, last float plate, following float plate, bloated head, crossbeam, pretension piece, the preload pressure device, base and through hole, two guide rails connect or run through top board from top to bottom, lower platen, the two ends of crossbeam and base; The catch bar upper end is run through top board and is connected pressure apparatus, the lower end is run through lower platen and is connected upward float plate, the expander roll upper end connects goes up float plate, float plate is down run through in the lower end, bloated head is positioned at the expander roll lower end, the pretension piece is fixed on the crossbeam lower surface, the preload pressure device places the crossbeam two ends, through hole is arranged in crossbeam and under the head that expands, the through hole internal diameter size is measure-alike with a maximum outside diameter that expands, and it is characterized in that: the head that expands is provided with bloated head part, enlarging and enlarging cover, the lower end of enlarging connects the head part that expands, and the upper end connects the enlarging cover.

Described pressure apparatus is large tank;

Described preload pressure device is small oil tank;

A block is set outside described expand tube;

Compared with prior art, one formation type electric tube expander of bloated enlarging of the present utility model solved the difficult problem that one moulding of bloated enlarging realizes, realized the bloated function that expands of multitube number simultaneously, improved efficient greatly.

Description of drawings

Fig. 1 is one formation type electric tube expander of a kind of bloated enlarging of the present utility model;

Fig. 2 is the schematic diagram of bloated head;

Wherein, 1-pressure apparatus, 2-top board, 3-catch bar, the 4-lower platen, the last float plate of 5-, 6-expander roll, the 7-guide rail, the bloated head of float plate 9-under the 8-, 10-crossbeam, 11-preload pressure device, 12-through hole, 13-pretension piece, the 14-base, 15-block, 16-expand tube, the 17-head part that expands, 18-enlarging, 19-enlarging cover.

The specific embodiment

Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, one formation type electric tube expander of bloated enlarging of the present utility model, one formation type electric tube expander of a kind of bloated enlarging, one formation type electric tube expander of a kind of bloated enlarging, comprise pressure apparatus 1,
