Description
Technical Field
The utility model relates to the field of pipe production equipment, in particular to a seamless pipe traction device.
Background
PE tubular product and PPR tubular product are more common water pipe, use extensively in the running water supply pipe way, and the demand is great.
The production of PE tubular product and PPR tubular product can not leave the extruder, carries out the extrusion of tubular product through the extruder, then cooling shaping, in order to promote the shaping quality of tubular product, still needs draw gear to carry out the drawing of tubular product usually, keeps the output at the uniform velocity, avoids retardant deformation problem. In the prior art, two sets of running rollers about adopting carry out pulling of tubular product more, but the area of contact of running roller and tubular product is little, skids easily, in order to avoid skidding, need increase the clamping-force of two sets of running rollers about to tubular product to lead to leaving the problem of trace on the tubular product surface, need improve.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a pipe traceless traction device which is used for carrying out uniform traction on a pipe and avoiding the problem of leaving clamp marks on the surface of the pipe.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a pipe traceless traction device comprising: the gantry is arranged on the base, the first conveying frame and the second conveying frame are arranged in the gantry at intervals from top to bottom, a first conveying belt is arranged in the first conveying frame, a second conveying belt is arranged in the second conveying frame, a plurality of circles of first trapezoidal grooves are formed in the first conveying belt in an inwards concave mode, and second trapezoidal grooves in one-to-one correspondence with the first trapezoidal grooves are formed in the second conveying belt.
The gantry is provided with a first lifting adjusting device connected with the top of the first conveying frame, and the base is provided with a second lifting adjusting device connected with the bottom of the second conveying frame.
The first lifting adjusting device and the second lifting adjusting device adopt oil cylinders, air cylinders or electric cylinders.
The number of the first trapezoidal grooves is 1-3 circles.
The inner side of the portal frame is vertically provided with a guide rail, first sliding blocks located on the guide rail are arranged on two sides of the first conveying frame, and second sliding blocks located on the guide rail are arranged on two sides of the second conveying frame.
Wherein, the first conveyer belt is parallel with the second conveyer belt.
The utility model has the beneficial effects that: the utility model provides a no trace draw gear of tubular product, the specially designed first conveyer belt and second conveyer belt, utilize first dovetail groove and the second dovetail groove that corresponds to carry out the centre gripping of tubular product, increase area of contact avoids skidding, ensures drawing at the uniform velocity to tubular product, can also avoid leaving the problem of pressing from both sides the trace on the tubular product surface, ensures tubular product surface quality.
