fig. 2 is a schematic view of the positive pressure welding head of the present invention.
In the figure, 1, an operation table, 2, an end plate, 3, a sliding seat, 4, a differential screw, 5, a hand wheel, 6, a threaded hole, 7, a positive pressure welding head, 8, a negative pressure welding head, 9, an upper clamping seat, 10, a lower clamping seat, 11, a pneumatic rod and 12, an arc-shaped groove are arranged.
Detailed Description
Fig. 1 is the structure schematic diagram of the utility model, a manual butt welding machine, including operation panel 1, the butt welding mechanism that is used for the clamping work piece and the differential screw mechanism that can supply the butt welding mechanism to control horizontal slip, differential screw mechanism erects on operation panel 1 through the end plate 2 of its both sides, and butt welding mechanism sets up on differential screw mechanism through the activity of the slide 3 of its bottom.
When the welding device is used, workpieces to be welded are clamped through two groups of butt welding mechanisms on the differential screw rod 4, then the hand-operated wheel 5 is used for driving the positive and negative pressure welding joints to synchronously and relatively move until the workpieces on two sides are contacted, and the contact surfaces of the two mutually butted metal workpieces are instantly heated to be melted and fused by using the resistance between the contact surfaces of the two workpieces and passing a low-voltage large current instantly, so that the welding is finished.
The differential screw mechanism comprises a differential screw 4 erected between the two side end plates 2 and a hand wheel 5 arranged at one end of the differential screw 4. The hand-operated wheel 5 is rotationally connected with the differential screw rod 4 through a pin shaft penetrating in the end plate 2, and the motion of the differential screw rod 4 is controlled through the rotation of the hand-operated wheel 5.
The outer surface of the differential screw 4 is symmetrically provided with thread sections, and the center of the sliding seat 3 is provided with a threaded hole 6 matched with the thread sections. When the differential screw rod 4 rotates clockwise, the sliding seats 3 on the two sides synchronously move relatively, the distance is reduced, and when the differential screw rod 4 rotates anticlockwise, the sliding seats 3 on the two sides move reversely, and the distance is increased.
The butt welding mechanism comprises a positive pressure welding head 7 and a negative pressure welding head 8 which are symmetrically arranged at two ends of the differential screw 4, and the positive pressure welding head 7 and the negative pressure welding head 8 are detachably connected with the sliding seat 3 through bolts. The welding head specification can be changed according to the user demand, bolted connection makes the dismantlement simple to operate of welding head swift, and positive pressure welding head 7 and negative pressure welding head 8 pair the setting to guarantee that the both sides work piece is at same height, do benefit to accurate welding.
As shown in fig. 2, the positive pressure welding head 7 and the negative pressure welding head 8 each include an upper holder 9, a lower holder 10, and a pneumatic rod 11, and the pneumatic rods 11 for the upper holder 9 to move up and down longitudinally are disposed at two ends of the lower holder 10.
The distance between the upper clamping seat 9 and the lower clamping seat 10 is adjusted through a pneumatic telescopic rod, and workpieces to be welded are clamped tightly through the extrusion effect of the upper clamping seat and the lower clamping seat, so that the workpieces cannot shift in the welding process, and the normal welding is guaranteed.
The splicing surfaces of the upper clamping seat 9 and the lower clamping seat 10 are correspondingly provided with arc-shaped grooves 12 which are convenient for clamping pipe fittings. When needs butt welding pipe fitting, alright with directly placing the pipe fitting and press from both sides tightly fixedly in arc wall 12, when needing the butt welding flat plate, with the plate level place on arc wall 12 can.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
