The specific embodiment

Tank body forming machine described in the utility model, comprise underframe 4, at least two pairs of mechanical arms are installed on the underframe 4, the big I of rolling tank body according to volume is provided with three pairs, four pairs, five pairs or how right mechanical arm, but, how described the volume and weight of the more make-up machine of quantity of mechanical arm be also just big more, and its manufacturing cost is just high more; As shown in Figure 2, but two mechanical arm left-right symmetry in described every pair of mechanical arm distribute, wherein every mechanical arm is by following brake arm 11, last brake arm 6, second hydraulic cylinder 27 and the 3rd hydraulic cylinder 7 connect and compose, one end of following brake arm 11 is hinged with underframe 4 by first 5, the other end of following brake arm 11 is hinged by the 5th 24 end with last brake arm 6, the other end of last brake arm 6 is installed first roll 10, first roll 10 is connected with last brake arm 6 by 30,30 are connected with last brake arm 6, first roll 10 can rotate relative to 30, one end of second hydraulic cylinder 27 is hinged with underframe 4 by the 8th 28, the other end of second hydraulic cylinder 27 is hinged with last brake arm 6 by the 7th 26, be positioned at first 5 below for the 8th 28, be generally convenient and install the 7th 26 between first 5 and the 5th 24, one end of the 3rd hydraulic cylinder 7 is hinged with following brake arm 11 by the 4th 23, the other end of the 3rd hydraulic cylinder 7 is hinged with last brake arm 6 by the 6th 25, be generally easy for installation, can make the 6th 25 between first roll 10 and the 5th 24; On the underframe 4 hold down gag is installed.For conveniently installing and fixing second hydraulic cylinder 27 and following brake arm 11 fixed support 12 and base 29 can be set on underframe 4.

During use, as shown in Figure 1 to Figure 3, earlier workpiece 19 is positioned over described many on the mechanical arm, and mould 13 spoted weld on the workpiece 19, usually mould 13 can be according to the same or analogous dividing plate of tank body transverse shape, length according to tank body can be put two to four moulds 13 of burn-oning on workpiece 19, when tank body is longer, also can put burn-on five or more a plurality of mould 13; Restart described hold down gag, make described hold down gag by mould 13 workpiece pressings 19; Then, start second hydraulic cylinder 27 and the 3rd hydraulic cylinder 7 on the described mechanical arm, second hydraulic cylinder 27 drives down that brake arm 11 rotates relative to underframe 4, the 3rd hydraulic cylinder 7 drive upward brake arm 6 relative under brake arm 11 rotate, thereby make workpiece 19 steadily become folding along the curve of mould 13; After volume rolls bending to a certain degree, make the welder weld in tank interior, soon workpiece 19 rolls in the process at volume and partly is weldingly fixed on mould 13 closely with mould 13 applyings, prevent workpiece 19 resiliences, also can reduce simultaneously the load of mechanical arm, have energy-saving effect preferably, repeat the action that above-mentioned volume rolls bending and welding, until workpiece 19 is bent into tank body fully; At last with the two ends welded closed of workpiece 19, and mould 13 removed promptly finish volume and roll into type work.

As Fig. 2, Fig. 4, Fig. 5 and shown in Figure 6, described hold down gag can be connected and composed by two hold-down mechanisms and crossbeam 3, as shown in Figure 1, all mechanical arms are all between described two hold-down mechanisms, each hold-down mechanism can be connected and composed by bracing frame 2, support 15, first hydraulic cylinder 17, and mounting bracket 15 on the bracing frame 2, and first hydraulic cylinder 17 is installed on the support 15, crossbeam 3 is installed on the piston rod of two first hydraulic cylinders 17 of described two hold-down mechanisms, and crossbeam 3 is positioned at the top of described mechanical arm.Volume rolls in the process, after spoting weld mould 13 on the workpiece 19, first hydraulic cylinder, the 17 common pulling crossbeams 3 that start 17, two described hold-down mechanisms of first hydraulic cylinder move down compaction mold 13, mould 13 workpiece pressings 19 prevent that move up influence volume of workpiece 19 from rolling effect under the driving of mechanical arm.

For ease of adjusting the position of crossbeam 3, guarantee to compress effect, as shown in Figure 6 with respect to mould 13, chute 21 is offered on the top of support 15, roller 14 is installed in the chute 21, and the quantity of roller 14 can be four, six or eight, can be as the criterion along bracing frame 2 smooth sliding to guarantee support 15; , as shown in Figure 6, the cross section of bracing frame 2 is I-shaped, and roller 14 cooperates with bracing frame 2, and roller drive 1 is installed on the support 15, and the output shaft of roller drive 1 is connected with roller 14; For guaranteeing that support 15 moves steadily, on the support 15 can about respectively install 1, two roller drive of a roller drive 1 respectively two rollers 14 connect, the roller 14 that is connected with roller drive 1 is called driving wheel; For convenient first hydraulic cylinder 17 of installing, simultaneously crossbeam 3 is play the guiding role, can offer groove 32, the first hydraulic cylinders 17 on the support 15 and be positioned at groove 32.For convenient piston rod with first hydraulic cylinder 17 is connected with crossbeam 3, the piston rod that contiguous block 20, the first hydraulic cylinders 17 can be installed on the piston rod of first hydraulic cylinder 17 is connected with crossbeam 3 by contiguous block 20.

Described hold down gag also can be directly by bracing frame 2, hydraulic cylinder and crossbeam 3, described hydraulic cylinder is installed on the bracing frame 2, crossbeam 3 is installed on the piston rod of described hydraulic cylinder, described hydraulic cylinder is positioned at the top of crossbeam 3, when volume rolls, start described hydraulic cylinder, described hydraulic cylinder promotes crossbeam 3 downwards, utilize crossbeam 3 that mould 13 is compressed, thus workpiece 19 is fixing.But through the real hold down gag of learning this structure entirely of volume its to compress effect not ideal.

For improving the effect that volume rolls bending, the bottom of workpiece 19 can be fitted tightly with mould 13 as far as possible, can support roller 31 be installed on underframe 4, support roller 31 is positioned at the bottom of workpiece 19, and support roller 31 can be together between two mechanical arms to mechanical arm.Support roller 31 can cooperate up and down with crossbeam 3 exerts pressure to workpiece 19, makes the bottom of workpiece 19 more be close to mould 13, and support roller 31 workpiece 19 rollings relatively simultaneously can prevent to roll scuffing workpiece 19 surfaces in the process at volume.For increasing the contact area of support roller 31 and workpiece 19, further make the bottom of workpiece 19 stressed evenly, as shown in Figure 1, can many group support rollers 31 be set according to the roll up length of rolling tank body, can form by four support rollers 31 for every group.

For guaranteeing the same moved further of each mechanical arm, roll effect to improve volume, as shown in figures 1 and 3, two of homonymy is installed connecting axle 9 between adjacent first 5.

For making workpiece 19 roll in the process stressed even at volume, as shown in figures 1 and 3, second roll, 8, the second rolls 8 are installed between two adjacent first rolls 10 of homonymy can increase contact area with workpiece 19, and second roll 8 cooperates with first roll 10 makes its bending to workpiece 19 application of forces.

Roll the stroke of bending for increasing volume, guarantee that workpiece 19 is the loading process of a steady gradual change in the bending process, simultaneously, also in order to increase the contact area that goes up brake arm 6 and workpiece 19, go up the stroke that 6 pairs of workpiece of brake arm, 19 volumes roll to increase, as shown in Figure 2, cambered surface 33 can be made in the upper surface of last brake arm 6.

For preventing that cambered surface 33 and workpiece 19 from scratching workpiece 19 because of friction, as shown in Figure 2, installation carrying roller 22 on the last brake arm 6, carrying roller 22 and guarantee that carrying roller 22 is positioned at cambered surface 33 places between first roll 10 and the 6th 25.Under volume rolled initial state, as shown in Figure 2, carrying roller 22 was higher than first roll 10, and carrying roller 22 contacted with workpiece 19 at the beginning of volume rolled.

The utility model not technology contents of detailed description is known technology.
