Fastening machine for rubber pipe unit assemblage

The utility model relates to equipment used for the connection of flexible pipes, particularly the equipment of hydraulic rubber pipes, air conditioning rubber pipes and a petroleum and chemical industry pipeline assembly. The utility model is characterized in that a lower V-shaped block 11 of a buckling part is fixed on an oil cylinder 10 by a foot supporting frame 19; an upper V-shaped block 13, which is fixed on a piston rod 12 by screw nuts 14 and locking screw nuts 15, moves up and down with the piston rod 12; four 90 DEG dovetail-shaped pressing blocks 24 are correspondingly installed on the four vertical corners of the V-shaped blocks 11 and 13; four die seats 23 are installed among the four dovetail-shaped pressing blocks 24 by guide keys 26; compression springs 27 are installed among the die seats 23 and the end faces of the dovetail-shaped pressing blocks 24; dies 21 are installed on the die seats 23 and on the dovetail-shaped pressing blocks 24 by transition dies 22. The equipment is favorable for the connection of bent pipe joints and flange type joints and enhances the buckling force of a buckling machine to fully satisfy the requirements of various rubber pipe assemblies. Compared with a frame type buckling machine, the utility model has the advantages of simple structure, low processing cost, stable complete machine operation, high buckling precision and low labor intensity.
