As a kind of preferred version, be provided with protective sleeve at the two ends of workpiece to be formed.
As a kind of preferred version, also be provided with adjustment screw on bracing frame.
As a kind of preferred version, described base plate is fixed on gap-framepress.
Use the method for the machining large-sized break-resistant hook of described device, comprise the steps:
A) with the bar two ends good screw thread of car on request;
B) the semi-finished product workpiece of the good screw thread of two ends car heated;
C) regulate the spacing of moulding upper left mould and moulding upper right intermode according to the break-resistant hook size of required processing, and the locking shaping upper;
D) the semi-finished product workpiece after heating is put into shaping upper, and is enclosed within the end of thread of semi-finished product workpiece with protective sleeve;
E) the dynamo-electric machine of starting pressure;
F) step on the forcing press floor push, shaping upper moves downward under the drive of the slider-crank mechanism of forcing press, completes shaping work;
G) loosen set lever, open shaping upper, with fixture, the break-resistant hook that processes is taken out.
Compared with prior art, because the utility model device can be realized first cutting thread, hot repressing moulding, can save annealing operation, therefore, not only simplify the processing technology of large scale break-resistant hook, shortened the process-cycle, improved production efficiency, and guaranteed to have reduced production cost by end product quality; In addition, the utility model device also has the advantages such as simple in structure, easy to use, dimension adjustable, has industrial applications and is worth.
