Description
[technical field]
The utility model relates to pole doffer technical field, specifically installs simple pole doffer additional and just can carry out blanking to hot rolling and cold-drawn steel round bar on bar cropper.
[background technology]
Usually circle handful blanking carries out on the universal machine forcing press, needs special-purpose blanking die.If the round bar of same size, the price of used universal machine forcing press is eight to ten times of bar cropper, the manufacturing cost of special-purpose blanking die is also far above this device, the power consumption of universal machine forcing press simultaneously also substantially exceeds this device, and also not having the pole doffer on the bar cropper at present, round bar is subjected to shearing the effect of moment of flexure when cutting off and produces not tiltedly like this, thereby makes shearing area produce gradient, pressure its external diameter surface that collapses influences the quality that round bar is sheared greatly.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and pole doffer on a kind of new reinforcing steel bar cutting machine of providing.
Design the pole doffer on a kind of new reinforcing steel bar cutting machine for achieving the above object, comprise cutting machine support, movable knife plate, fixedly knife plate, spacing mechanism, guide holder, fairlead are formed, it is characterized in that cutting machine support (2) upper surface is equipped with a groove, guide holder (18) is housed in the groove, guide holder (18) inside has circular hole, the circular hole fairlead (16) that is connected, fairlead (16) rear end is connected and fixed knife plate (14), fixing knife plate (14) the activity knife plate (3) that is connected, cutting machine support (2) rear end face is provided with spacing mechanism; Spacing mechanism comprises spacing support, spacing supporting plate, spacing pin, spring and fine setting nut composition, cutting machine support (2) rear end face connects spacing support (4), spacing support (4) adopts sleeve pipe (11) to fixedly connected spacing supporting plate (9) with screw (10), spacing support (4) and spacing supporting plate (9) are provided with spacing pin (8), are with spring (7) and fine setting nut (6) on the spacing pin (8); Fixedly knife plate (14) has circular hole on the position that matches with fairlead (16); Movable knife plate (3) is provided with semi-circular recesses at the relevant shear position; Fairlead (16) only adopts, and a screw (15) is fixedly connected on the guide holder (18); Guide holder (18) adopts screw (1) to be fixedly connected on the cutting machine support (2); Spacing support (4) adopts screw (5) to be fixedly connected on cutting machine support (2) rear end face.
The utility model produces not tiltedly to prevent round bar to be subjected to shearing the effect of moment of flexure when cutting off, thereby makes shearing area produce gradient.Fairlead is housed in the guide holder, and its internal diameter can be changed according to the diameter of round bar is different.Fairlead after heat treatment has certain degree of hardness, can prevent wearing and tearing, increases service life.Change original fixedly knife plate of bar cropper and movable knife plate, new fixedly knife plate has the circular hole that matches with the round bar diameter on the position that matches with fairlead, new movable knife plate is provided with the semi-circular recesses profile that matches with the round bar diameter at the relevant shear position, both press its external diameter surface that collapses as shearing edge in the time of can preventing the pole blanking effectively.Fixedly the wearing and tearing of knife plate and movable knife plate shear plane are after reconditioning is reusable, in order to guarantee the reasonable shear gap between two knife plates, need fill out and the fixing copper sheet of knife plate reconditioning quality equal thickness in the one side that fixedly knife plate and support are fixed.
In order to guarantee the blanking length of pole blanking, the utility model is provided with round bar and sends spacing mechanism to.Certain axial movement value is arranged when considering the pole blanking, damage, on the spacing pin spring is housed in order to prevent spacing mechanism.The size of spring force is wanted suitably, and at first spring force is greater than round bar impulsive force to the spacing pin when sending to, otherwise will influence the spacing precision, and the axial float that also will guarantee spacing pin pole when being subjected to blanking simultaneously can be made and being dodged.According to different spacing length, select the spacing pin of different length.The fine setting nut is housed on the spacing pin, in blanking, can adjusts blanking length as required at any time.
The utility model compared with prior art, novel structure, simple, easy to use, just can carry out blanking to hot rolling and cold-drawn steel round bar on bar cropper, can guarantee shearing quality, the efficient of blanking also improves greatly, and the utility model low cost of manufacture, be worthy of popularization.
