Problems solved by technology

This type of material uses one hydraulic cylinder to directly clamp the two opposite surfaces, which is not reliable. If two hydraulic cylinders are used to clamp on all sides, the clamping mechanism is too large and the cost is high.

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0024] Such as Figure 1 to Figure 4 As shown, a multi-directional clamping device for stretch bending, including:

[0025] The clamping assembly 1 is used for clamping the profile 4. The clamping assembly 1 includes a No. 1 clamping block 11, a No. 2 clamping block 12, a No. 3 clamping block 13, a No. 4 clamping block 14, a taper sleeve 15, a lock nut 16 and T-shaped joint 17, No. 1 clamping block 11, No. 2 clamping block 12, No. 3 clamping block 13 and No. 4 clamping block 14 are evenly distributed on the outside of the profile 4, and are used to clamp the four sides of the profile 4. The No. 1 clamp Block 11, No. 2 clamping block 12, No. 3 clamping block 13 and No. 4 clamping block 14 are all located in the taper sleeve 15, and the larger end of the taper sleeve 15 is connected with the lock nut 16, and the No. 1 clamping block 11 and No. Clamp block 12,...

Abstract

The multi-directional clamping device comprises a clamping assembly used for clamping a profile, a driving assembly used for driving the clamping assembly and a core penetrating assembly used for supporting the profile from the inner side, and the clamping assembly comprises a first clamping block, a second clamping block, a third clamping block, a fourth clamping block, a taper sleeve, a locking nut and a T-shaped connector. The first clamping block, the second clamping block, the third clamping block and the fourth clamping block are circumferentially and evenly distributed on the outer side of the profile and all hung on the T-shaped connector. Multi-face clamping of the profile is achieved through the driving assembly, the driving assembly is equivalent to an oil cylinder, one oil cylinder is omitted compared with a straight clamping type, and cost is saved; by means of the wedge force amplification effect of the taper sleeve, reliable clamping of the small oil cylinder to the large-section profile is achieved. In addition, the core penetrating assembly is used for supporting the sectional material from the inner side, and the sectional material is prevented from deforming when clamped.

Description

technical field [0001] The invention relates to the technical field of profile stretch bending, in particular to a multidirectional clamping device for stretch bending. Background technique [0002] When the profile is stretched and bent, it is necessary to clamp the two ends of the straight profile safely and reliably, and then bend it according to the mold. When forming and clamping the common one-shaped cross-section products such as some automobile door frames and waist trim strips, a single hydraulic cylinder can be used to move up and down to directly clamp the two opposite surfaces of the profile to achieve stable clamping and forming. However, when other cross-section profiles, such as bumper beams with rectangular cavity cross-sections, and decorative strips on T-shaped cross-sections, are formed by stretch bending, clamping blocks are required to surround the entire cross-section to achieve stable clamping and forming. This type of material uses one hydraulic cyli...
