Description

Many spaces hydraulic pipe bender

The utility model belongs to the section bar processing equipment, particularly a kind of many spaces hydraulic pipe bender.

Bend pipe processing is the curved shape that bending pipes is become to meet people's needs.At present the hydraulic pipe bender that uses because the fuselage design is unreasonable, causes workpiece to be subjected to certain limitation in process, and is especially bigger for bending radius, and many curved barrel spares that connects only can bend single bending on bending machine, and can not the continuous bend moulding.So have to employing earlier with after the tubing brachymemma, curve single bending, weld the mode that is linked to be the complicated shape pipe then after the polishing again and finish many curved processing.Especially for still needing through the x-ray detection check after the welding of pressure-bearing pipe fitting, be prone to distortion after the welding, cause the physical dimension error of workpiece, directly influence the inside and outside quality of workpiece.Therefore, the bending machine of former use is not only processed bothersome, the cost height; But also can not satisfy quality requirement.The more important thing is the scope of bending of pipe fitting is brought certain limitation.

The purpose of this utility model provides a kind of many spaces hydraulic pipe bender, it can be continuous the bending of carrying out pipe fitting, and can bending go out different space angle and bending radius, as carrying out steel pipe, the bending process of square tube and rectangle steel, hydraulic pipe bender adopt hydraulic-driven and clamp finishes various bend pipe actions, lathe integral structure layout is reasonable, easy to operate, quick, widened the scope of bending.

The purpose of this utility model is achieved in that many spaces hydraulic pipe bender, comprise support, hydraulic system and electric control system, upper part of the frame is provided with pipe bending roll, and be fixed on the bend pipe axle top of vertical direction, the transmission device that drives the pipe bending roll rotation is arranged on the bend pipe axle of support bottom, the pipe bending roll outside is provided with and compresses the hold down gag for the treatment of crooked workpiece, it is characterized in that: be equipped with on the support and add long guideway, the chucking oil cylinder is arranged on and adds the long guideway rear end, the piston rod of chucking oil cylinder connects with the gripping mechanism of corresponding pipe bending roll according to the guiding mechanism on the guide rail, and gripping mechanism is moved horizontally by the piston rod drive on guide rail in the lump with guiding mechanism.

Above-mentioned guide rail can be designed to two-way guide rails, the chucking oil cylinder is arranged between the two-way guide rails between two parties, the piston rod of chucking oil cylinder is connected with one end of the guiding mechanism with two way slide lane that two-way guide rails is connected, and the two way slide lane other end connects with the gripping mechanism of corresponding pipe bending roll.

Above-mentioned gripping mechanism is made up of the vertical chucking roll shaft that cuts with scissors the tight roller that is installed of installing on the support that is connected with guiding mechanism, the support.

The above-mentioned long guideway cantilevered that adds is loaded on the support, and its cantilever end that adds long guideway is equipped with supporting leg.

The utility model is compared embodiment with original equipment superiority is: many spaces hydraulic pipe bender is because reasonable in design, has good operating space, can continuous bend have the curved pipe fitting of a plurality of bendings, and can bending go out the different space angles and the workpiece of bending radius, as carry out steel pipe, and the bending process of square tube and rectangle steel, the chucking drive unit that adds on the long guideway adopts hydraulic control, and workpiece is bent more accurately and reliably by guiding mechanism guiding, operate easily laborsaving.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the front view of space hydraulic pipe bender embodiment.

Fig. 2 is the vertical view of space hydraulic pipe bender embodiment.

Fig. 3 is the A-A cutaway view among Fig. 1.

Among Fig. 1, Fig. 2 and Fig. 3:

1 pipe bending roll, 2 bend pipe axles, 3 worm gears, 4 worm screws, 5 supports, 6 chucking rollers, 7 chucking roll shafts, 8 chucking supports, 9 chucking oil cylinder and piston rods, 10 hold down gags, 11 add long guideway, 12 guiding mechanisms, 13 supporting legs, 14 hydraulic systems.

Figure 1 and Figure 2 is the utility model embodiment, pipe bending roll 1 horizontal direction is installed in Fig. 1, its outer rim has the semicircle arc groove that adapts with the tubing cross sectional shape, the processing different size, the bend pipe of angle and shape need use different pipe bending roll 1, pipe bending roll 1 arc groove place has and compresses the hold down gag 10 for the treatment of the swan-neck material, hold down gag 10 fixes with pipe bending roll 1, pipe bending roll 1 is fixed on the upper end of the bend pipe axle 2 of vertical direction, worm gear 3 is equipped with and the transmission that is meshed with worm screw 4 in bend pipe axle 2 middle parts, and worm gear 3 drives bend pipe axles 2 and pipe bending roll 1 rotates.Chucking roller 6 be less disc-shape, and its outer rim has the semicircle arc groove that adapts with the tubing cross sectional shape, and chucking roller 6 is installed on the chucking roll shaft 7 of vertical direction and can freely rotates thereon, tightens roll shaft 7 and is installed in and tightens on the support 8.Support 5 upper cantilever formulas are equipped with and add long guideway 11, its cantilever end that adds long guideway 11 is equipped with supporting leg 13, chucking oil cylinder and piston rod 9 are arranged on and add long guideway 11 rear ends, and chucking oil cylinder and piston rod 9 are connected according to the chucking support 8 on the gripping mechanism that adds the guiding mechanism with two way slide lane 12 that is connected with two-way guide rails and corresponding pipe bending roll 6 on the long guideway 11.And gripping mechanism moves horizontally adding on the long guideway 11 to be driven by piston rod in the lump with guiding mechanism 12.Chucking oil cylinder and piston rod 9 push card locking brackets 8, chucking roll shaft 7, chucking roller 6 advances or retreats adding on the long guideway 11 horizontal direction according to guiding mechanism 12.
