Abstract
The utility model relates to a forging machine which comprises a main machine frame, an upper fixing beam, pre-stressing force pull rods, a movable beam, a return cylinder, a plunger type cylinder, a guide device, a movable worktable, a transverse moving anvil, an upper anvil and a lower anvil. The pre-stressing force pull rods are fixed on the upper fixing beam through a pre-tightening device, pushing screws vertically penetrate through a pre-tightening nut to abut against a base plate located between the pre-tightening nut and the upper fixing beam, and the base plate abuts against the pre-tightening nut upwards and stretches the pre-stressing force pull rods. The forging machine has the advantages that the pre-stressing force pull rods carry out pre-tightening operations through the pre-tightening nut, the pushing screws and the base plate, what is needed is to tighten the pushing screws with a torque wretch in a screwing mode, pre-tightening operation of the upper fixing beam and the main machine frame are completed, installation cost is saved, operation methods are simple, a single person can finish the operation, labor cost is saved, threads are needless to be machined on the tops of the pre-stressing force pull rods, the structures of the pre-stressing force pull rods are simplified, and under long-term alternating load, and the pushing screws on the top of the pre-tightening nut provides a guarantee to loosen the pre-stressing force pull rods.
Description
Technical field
The utility model belongs to the forging press technical field, relates in particular to a kind of forging press that adopts pre-load nut stretching prestressed draw-bar to carry out pretension.
Background technology
Forging press is to be used for being shaped and separating in the forging and pressing converted products, transmits the metal forming machinery of operating pressure with highly pressurised liquid (oil, emulsion etc.).The forging press stable working, vibrations do not reach the bigger forging degree of depth easily, are suitable for the forging of heavy forging and the work such as pull and stretch, packing and briquetting of large-sized plates material most.
Need prestressed draw-bar to come pretension between the last fixed cross beam of cylinder moving type press and the mainframe, with rigidity and the anti-bias load ability that guarantees whole main computer unit, firmly beforehand means of the prior art mostly is and adopts the high power hydraulic spanner, need carry out pretension by means of hydraulic elongator for the large-tonnage press, owing to be at the top of press pretension, be subjected to the restriction in working depth and space, use hydraulic spanner or hydraulic elongator, it is all very difficult to operate; High-power torque wrench and hydraulic elongator are expensive, and this mode cost is higher; Need increase manufacturing procedure one at prestressed draw-bar top one section silk of processing to cooperate the use of hydraulic elongator when using hydraulic elongator, waste human cost, and prestressed draw-bar structure and processing technology are complicated; Under long-term alternate load, prestressed draw-bar is loosening easily, does not loosen guarantee reliably.
The utility model content
For prestressed draw-bar between fixed cross beam on solving in the background technology and the mainframe adopts hydraulic spanner or hydraulic elongator to carry out pretension, cost is higher, waste of manpower, complex procedures, the baroque defective of prestressed draw-bar, the utility model provide a kind of forging press that adopts pre-load nut stretching prestressed draw-bar to carry out pretension.
The technical solution of the utility model is:
A kind of forging press includes following structure,
Mainframe is inclined cross on travelling table also for bolster stake plug cylinder and kicker cylinder;
Last fixed cross beam is for the plunger that hangs the fixed leg plug cylinder;
The array prestressed draw-bar connects and is pre-loaded between mainframe and last fixed cross beam vertical, is fixed on the fixed cross beam by pre-tightening apparatus;
Moved cross beam is arranged between mainframe top and last fixed cross beam vertical and is used for being connected the drive end of kicker cylinder and the cylinder body of plunger case;
Plunger case, its cylinder body wear and are connected in mainframe and cylinder body bottom fit on anvil;
Travelling table arranges thereon and laterally moves anvil, laterally moves the following anvil that has on the anvil with last anvil coupling;
Described pre-tightening apparatus comprises and is enclosed within prestressed draw-bar upper end, and the pre-load nut that is threaded with the prestressed draw-bar upper end, between described pre-load nut and the last fixed cross beam backing plate is arranged, holding out against screw vertically passes pre-load nut and holds out against backing plate, backing plate holds out against pre-load nut upwards, the stretching prestressed draw-bar.
Technique effect of the present utility model is:
1) prestressed draw-bar adopts pre-load nut, pretension screw and backing structure to carry out pretension work, only need torque wrench to tighten the pretension screw, the pretension screw heads on backing plate, head on pre-load nut stretching prestressed draw-bar by reaction force, finish the pretension work of fixed cross beam and mainframe, needn't use hydraulic elongator and high power hydraulic spanner, the installing space that needs is little, has saved installation cost;
2) method of operating is simple, and single finishing saved cost of labor;
3) need not simplify the structure of prestressed draw-bar at prestressed draw-bar top processing silk, save manufacturing process and cost of labor;
4) under long-term alternate load, the pretension screw of pre-load nut end one circle loosens guarantee for loosening the providing of prestressed draw-bar.
