Description

A kind of processing unit (plant) of hydraulic pendulum plate shears upper tool post helicoid

Technical field

The utility model relates to a kind of process equipment of shearing tool of plate shearing machine, particularly the processing unit (plant) of plate shearing machine upper tool post.

Background technology

In the prior art, the upper tool post of hydraulic pendulum plate shears is under the effect of left and right oil cylinder and nitrogen kicker cylinder, around the bolster reciprocally swinging, finish shear action, because there is an angle α (α=1～4 °) in the horizontal plane of cutter and lathe, in order to guarantee the even uniformity in gap between the upper and lower blade cutting edge, the cutter cutting edge is necessary for a helix, because the helical pitch of this helix is very big, can't process with the method for normal process helix.At present, this helicoid adopts the mode that adds the backing plate compensation to process on planer, promptly between the blade installed surface of cutter and upper tool post, add a helicoid backing plate and raise blade height, force blade to become a helicoid to reach uniformity with the bottom knife gap, the shortcoming of this method is: the machining accuracy of backing plate is difficult to guarantee, the assembling difficulty, difficulty is adjusted in the cutting edge gap, thereby causes the complete machine low precision.

The utility model content

The purpose of this utility model provides a kind of processing unit (plant) of upper tool post of hydraulic pendulum plate shears,

The purpose of this utility model is achieved in that a kind of processing unit (plant) of hydraulic pendulum plate shears upper tool post helicoid, comprise die holder and delivering gear, be fixed with the working face gauge finder of face in the shape of a spiral on the die holder, described delivering gear comprises the roller of conflict on the gauge finder working face, roller is arranged on the rolling wheel support, but rolling wheel support is fixed on the planker of clamping cutter, planker is arranged on the slide rail, fix an end in the same way with slide rail on the slide rail and be the push rod of thread segment, the thread segment of push rod is provided with adjusting nut, be socketed with spring on the push rod, spring one end is conflicted on planker through spring base, and the spring other end is conflicted on adjusting nut through spring base.

During the utility model work, slide rail can be arranged on the guide rail bracket of metal-planing machine, simultaneously die holder and planer lathe bed are fixed, regulate adjusting nut, spring can drive planker and move to gauge finder, roller is contacted with imitation profile on the gauge finder, during planer work, roller can along gauge finder in the shape of a spiral the working face of face move, the planker that fixes with rolling wheel support then drives the forms of motion that cutter is consistent, cutter then can be processed into the workpiece that is clamped on the planer and the corresponding to helicoid of gauge finder, this device can be used for the processing of hydraulic pendulum plate shears tool-post screw face, when reality is implemented in the process, existing metal-planing machine can be reequiped, promptly replace planker and slide rail, change the leading screw of carriage saddle bottom into push rod with the carriage saddle of metal-planing machine and guide rail bracket assembly, and push rod and guide rail bracket fixed, the remainder structure remains unchanged.As seen, the utility model is implemented convenient, its machining accuracy depends on the precision of machine tool accuracy and gauge finder itself, therefore, select suitable lathe and gauge finder, can process the helicoid that conforms with required precision, its production technology is simple, with low cost, the precision height can directly be implemented on existing universal machine tools.

As further improvement of the utility model, be connected with auxiliary delivering gear on the described planker, auxiliary delivering gear comprises fixedly connected handwheel and screw mandrel, screw axis is to fixing with a sliding seat, sliding seat is threaded on the planker, screw mandrel matches with a nut seat, and described nut seat is threaded on the slide rail.During the processing helicoid, will assist delivering gear to remove; Add man-hour carrying out other, can unclamp adjusting nut, roller and gauge finder are thoroughly broken away from, also can remove roller and rolling wheel support, load onto auxiliary delivering gear then, auxiliary delivering gear is connected planker with slide rail, and handles wheel drive feed and withdrawing; This technical scheme can be carried out other processing to workpiece under the situation of travelling workpiece not, machining accuracy is improved.
