Abstract
A pipe bender is composed of a fixed part with a circular arc first slot, a rotary part linked to said fixed part in rotary mode, a roller linked to said rotary part in rotary mode, and a second slot with an open end opposite to the open end of said first slot. When the pipe fitting is bent, the pipe fitting is positioned in a space formed by the first groove and the second groove, the second groove is formed on the outer circumferential surface of the roller, and when the rotating member is operated, the roller rotates, so that the pipe fitting is not easily crushed.
Description
Technical field
The utility model relates to a kind of bending machine.
Background technology
Bending machine of the prior art, the tumbler that comprises the fixture of first groove, is rotationally connected with described fixture with circular arc, the axial line of the rotation pivot of described fixture and described tumbler and described first groove around the center of circle of circle coincide, bending machine in the market is when bend pipe spare, and pipe fitting is crushed easily.
Summary of the invention
The utility model purpose provides a kind of bending machine, and pipe fitting is difficult for being crushed when bend pipe spare.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bending machine, the tumbler that comprises the fixture of first groove, is rotationally connected with described fixture with circular arc, the axial line of the rotation pivot of described fixture and described tumbler and described first groove around the center of circle of circle coincide, on described tumbler, be connected with roller rotationally, external peripheral surface along described roller has second groove, and the peristome of described second groove is facing to the peristome of described first groove.
Because technique scheme utilization, the utility model compared with prior art has following advantage: during owing to bend pipe spare, pipe fitting is positioned at the space of first groove and the formation of second groove, described second groove is opened on the external peripheral surface of described roller, during the operation tumbler, roller rotates, thereby pipe fitting is difficult for being crushed.
Description of drawings
Accompanying drawing 1 is a stereogram of the present utility model;
Accompanying drawing 2 is the cutaway view of the A-A direction of accompanying drawing 1;
Wherein: 1, support; 2, first groove; 3, tumbler; 4, pipe fixture; 5, holddown groove; 6, second groove; 7, roller; 8, guide; 9, gathering sill; 10, turning rolls; 11, screw rod; 12, hole; 13, nut; 14, fixture;
The specific embodiment
As shown in Figure 1, a kind of bending machine, comprise support 1, described support 1 is provided with the fixture 14 of first groove 2 with circular arc, the tumbler 3 that is rotationally connected with described fixture 14,2 of the axial line of described fixture 14 and the rotation pivot of described tumbler 3 and described first grooves around the center of circle of circle coincide, as accompanying drawing 1, shown in the accompanying drawing 2, offer gathering sill 9 on the described tumbler 3, be provided with guide 8 slidably in the described gathering sill 9, described roller 7 is arranged on the described guide 8 rotationally, external peripheral surface along described roller 7 has second groove 6, and the peristome of described second groove 6 is facing to the peristome of described first groove 2.Between described guide 8 and described tumbler 3, be provided with the position adjusting mechanism of guide 8.
As shown in Figure 2, the position adjusting mechanism of described guide 8 comprises screw rod 11, fixedlying connected with described guide 8 in one end of described screw rod 11, threadably is socketed with nut 13 on the described screw rod 11, and an end of described nut 13 is against on the described tumbler 3 rotationally.
Described fixture 14 head lamp brush guard pivots are connected with an end of pipe fixture 4, and the other end has holddown groove 5
During operation, pipe fitting is placed on simultaneously in the space and described holddown groove 5 of described first groove 2 and 6 formation of described second groove, operate described tumbler 3, make described tumbler 3 rotate around the axial line of described fixture 14 with the rotation pivot of described tumbler 3, this moment, pipe fitting was pressed by curved, so pipe fitting is difficult for being crushed adjusting nut 13, make the space that forms between second groove 6 and described first groove 2 become big, be convenient to and taken off by the pipe fitting after curved the pressure.
As shown in Figure 2, the space that forms between described second groove 6 and described first groove 2 can be regulated by position adjusting mechanism, therefore can bend the multiple pipe fitting that thickness differs.
