Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a manual swan neck system, comprising a base plate 1, curved pressure head 4 and die wheel 3, the outside of pressure head 4 is equipped with the V-arrangement groove, the V-arrangement groove is used for the joint pipe, die wheel 3 and pressure head 4 are in same level, the backup pad 2 of bottom plate 1's bottom both sides fixedly connected with L shape, die wheel 3 is equipped with two and symmetrical setting on bottom plate 1, the plug-type quick tong 5 of upside fixedly connected with of bottom plate 1, pressure head 4 is installed on the push rod of quick tong 5, pressure head 4 is located the symmetric line department of two die wheels 3, it can promote pressure head 4 flexible to pull the handle of quick tong 5, utilize pressure head 4 will block the tubular metal resonator between two die wheels 3 and bend.

The bottom of the bottom plate 1 is fixedly connected with a guide rail 6, two sliders 7 are slidably connected in the guide rail 6, a vertical shaft is fixedly connected to the sliders 7, a die wheel 3 is rotatably connected to the upper end of the vertical shaft, two symmetrical strip holes are formed in the bottom plate 1, the vertical shaft penetrates through the strip holes and is slidably connected with the strip holes, a lead screw 10 penetrates through the support plate 2 and is in threaded connection with the support plate, the inner end of the lead screw 10 is rotatably connected to the middle of the connecting seat 8, two symmetrical connecting rods 9 are hinged to the connecting seat 8, the other end of each connecting rod 9 is hinged to the corresponding slider 7 on one side, a hand wheel 11 is fixedly connected to the outer end of the lead screw 10, a trapezoidal transmission thread section is arranged outside the lead screw 10, the lead screw 10 can be driven to rotate through the hand wheel 11, the connecting seat 8 can be driven to move, the connecting seat 8 drives the two sliders 7 and the die wheel 3 to move in the opposite directions or opposite directions through the connecting rods 9, the distance between the sliders and the angle of a bent pipe is adjusted.

Example two

The first difference from the embodiment is that a double-rotation-direction screw rod is used for driving the two sliding blocks 7 to synchronously move towards or away from each other to adjust the distance, the double-rotation-direction screw rod penetrates through the sliding blocks 7 and is in threaded connection with the sliding blocks, and a rocking handle is fixedly installed at the outer end of the double-rotation-direction screw rod.

The working principle is as follows: the pipe joint that will treat crooked during the use is between two mould wheels 3, then pulls quick-operation clamp 5 and promotes pressure head 4 and remove to the pipe and bend the pipe, when 5 three pin joints of quick-operation clamp were in same horizontal straight line, pressure head 4 removed extreme position and realized the lock and dies, consequently the pipeline that this device can be quick is crooked, is favorable to improving the efficiency of processing to the extreme position that pressure head 4 pressed the pipe at every turn is the same, thereby can guarantee the uniformity of return bend.
