At first; Hold-down mechanism is to utilize the face of cylinder of pinch rollers U font groove to be pressed in truss top on the prior art truss welding production line; Because the shape of pinch rollers U font groove can not fasteningly be pressed in the truss top of band tapering; Can not compress truss effectively, rocking appears in truss when cutting mechanism cutting truss, and quality is sheared in influence; Secondly, hold-down mechanism utilizes connecting plate to be fixed on the walking beam side, moves up and down with walking beam, and pinch rollers can not be regulated the pressure of pinch rollers to truss as required, causes the defective that compresses weak effect.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, provides a kind of pinch rollers ability the fastening truss top that is pressed in, and can regulate the hold-down mechanism of the truss welding production line of pinch rollers pressure as required.
The technical scheme that solves the problems of the technologies described above is: a kind of hold-down mechanism of truss welding production line, and said hold-down mechanism comprises: clamping frame, be pressed in the pinch rollers on the truss, said clamping frame one side is fixed on the walking beam, on clamping frame, is hinged with turning rolls; The hinged pinch rollers that is equipped with of one end of said turning rolls is equipped with the pressure-regulating device of regulating pinch rollers pressure between the other end of turning rolls and the clamping frame another side.
The beneficial effect of the utility model is: the utility model overcomes the defective of prior art, has simple in structurely, can easily adjust the thrust of pinch rollers to truss; Have on the fastening truss that is pressed in taper of the pinch rollers of V-shape sheave, truss is pressed stable on supporting seat, compacted truss is indeformable, improves the truss shearing quality; The utlity model has the low advantage of cost.

The specific embodiment
Embodiment to the utility model further details below in conjunction with accompanying drawing.
Fig. 1 is the front view of the utility model; Fig. 2 is the C-C cutaway view of Fig. 1; Fig. 3 is that the B of Fig. 1 is to view; Fig. 4 is that the A of Fig. 1 is to view; Fig. 5 is the D-D cutaway view of Fig. 1.
The utility model provides a kind of hold-down mechanism of truss welding production line, and said hold-down mechanism comprises: clamping frame 2, be pressed in the pinch rollers 4 on the truss 13; Said clamping frame 2 one sides are fixed on the walking beam 1, on clamping frame 2, are hinged with turning rolls 5; The hinged pinch rollers 4 that is equipped with of one end of said turning rolls 5 is equipped with the pressure-regulating device of regulating pinch rollers 4 pressure between the other end of turning rolls 5 and clamping frame 2 another sides.
Said pressure-regulating device comprises: extension spring 9, adjusting screw(rod) 3; Said extension spring 9 one ends are connected the other end of turning rolls 5, and extension spring 9 other ends are connected adjusting screw(rod) 3 one ends; Said adjusting screw(rod) 3 other ends are fixed on clamping frame 2 another sides with securing member.
Said pinch rollers 4 is sheaves of a V-shape, and the inclined-plane in the V font groove of said pinch rollers 4 can fastening truss triangular in shape 13 tops, cross section that are pressed in.
Said turning rolls 5 one ends are U font grooves, and first bearing pin 6 runs through and is fixed in U font groove two side through hole of turning rolls 5, and pinch rollers 4 is hinged on first bearing pin 6 in the turning rolls 5 one end U font grooves.
