Each of the fixed worktable and the rotary worktable is provided with a workpiece clamping die and a pressing device, and a driving mechanism for driving the rotary worktable to rotate around the pin is arranged on the fixed worktable. Workpieces are bent by means of driving the rotary worktable to rotate, bending angles of the workpieces can be manually controlled, the workpieces can be bent by various angles, and the workpieces of various thicknesses can be machined. The U-shaped beam bender has the advantages of simple structure, convenience in operation, high accuracy and high reliability.
Description
Technical field
The utility model relates to a kind of U type beam process equipment, particularly a kind of U type beam bender.
Background technology
At present in automobile industry; The need part that truck vehicle frame U type longeron and buttress brace have is bent into front wide and rear narrow (beloid) shape; Domestic processing method one to this is to adopt 3500 tons-4000 tons large pressing machine to be equipped with particular manufacturing craft, and is disposable with the section bar excellent suitability for press forming; The 2nd, adopt Driven by Hydraulic Cylinder rotation fuselage bending and forming.These two kinds of schemes all exist weak point now:
For first kind, because being the special steel, the longeron of truck and buttress brace process, because its tensile strength high (660-800Mpa), resilience is difficult to control, is difficult to reach designing requirement.And this processing method with large pressing machine forging and pressing is produced on the aerofoil of workpiece can emersion wave shape wave gauffer, also can occur workpiece distortion, surface tear phenomenon sometimes.On this equipment, a mold only can carry out bending to a kind of longeron of specification, has increased processing cost greatly in addition.
For second kind, there is the regular hour error in this hydraulic cylinder in reflection, and speed is influenced obviously by the resistance size.After speed regulation is fixing, can only be corresponding a kind of or several kinds of gauge material of similar thickness, thickness differs bigger still needing and regulate bending speed again, to avoid causing bigger trueness error.
Summary of the invention
The problem that the utility model will solve is: a kind of U type beam bender is provided, has made it can process the workpiece of plurality of specifications, multiple bending angle.
In order to address the above problem; The utility model comprises stationary work-table and is rotatably connected on the rotary table on the stationary work-table through bearing pin; Stationary work-table and rotary table are equipped with workpiece clamping mold and material pressing device, and stationary work-table is provided with the driving mechanism that the driven in rotation workbench rotates around bearing pin.
For the ease of the spring back angle after definite bending; Described rotary table is provided with the resilience checkout gear; The resilience checkout gear comprises cylinder, roller and linear displacement transducer; Roller is fixed on the piston rod of cylinder, and the cylinder body of cylinder is fixed on the rotary table, and linear displacement transducer is fixed on the cylinder block.
For reliable to U type beam workpiece location, described two workpiece clamp set of molds and become U-shaped workpiece bender floating die assembly.
The anglec of rotation for the ease of the control rotary table; Described driving mechanism comprises motor and leading screw screw mechanism; The support and the stationary work-table of motor are hinged, and the nut seat and the rotary table of leading screw screw mechanism are hinged, and an end of the leading screw of leading screw screw mechanism is connected with the output shaft of motor.
The beneficial effect of the utility model is: the driven in rotation workbench rotation passed through of the utility model realizes the workpiece bending, makes the bending angle of workpiece artificially to control, can be to workpiece bending multiple angles, and can process the workpiece of multiple thickness.The utility model also has simple in structure, and is easy to operate, and the degree of accuracy is high, the advantage of good reliability.
Description of drawings

Fig. 2, Fig. 3, Fig. 4 are the structural representation of three kinds of states in the Bending Processing process of workpiece.
Among the figure: 1, stationary work-table, 2, the binder oil cylinder, 3, rotary table, 4, the resilience checkout gear, 5, the workpiece clamping mold, 6, leading screw screw mechanism, 7, servomotor, 8, bearing pin, 9, workpiece.
The specific embodiment
A kind of specific embodiment as shown in Figure 1, it comprises stationary work-table 1 and is rotatably connected on the rotary table 3 on the stationary work-table 1 through bearing pin 8.
Stationary work-table 1 is equipped with workpiece clamping mold 5 and material pressing device with rotary table 3, and material pressing device adopts binder oil cylinder 2.
Stationary work-table 1 is provided with the driving mechanism that driven in rotation workbench 3 rotates around bearing pin 8; Driving mechanism comprises servomotor 7 and leading screw screw mechanism 6; The support of servomotor 7 and stationary work-table 1 are hinged; The nut seat and the rotary table 3 of leading screw screw mechanism 6 are hinged, and an end of the leading screw of leading screw screw mechanism 6 is connected with the output shaft of servomotor 7.
Rotary table 3 is provided with resilience checkout gear 4; Resilience checkout gear 4 comprises cylinder, roller and linear displacement transducer; Roller is fixed on the piston rod of cylinder; The cylinder body of cylinder is fixed on the rotary table 3, and linear displacement transducer is fixed on the cylinder block, and linear displacement transducer is used for the collapsing length of measurement of gas cylinder piston rod.
Two workpiece clamping molds 5 are formed U-shaped workpiece bender floating die assembly; U-shaped workpiece bender floating die assembly is open by Chinese patent 200520081481.X, in the U-shaped workpiece bender floating die assembly about two molds be separately positioned on stationary work-table 1 and the rotary table 3.
Operation principle: as shown in Figure 1, with workpiece 9 deliver to need the bending position after, workpiece clamping mold 5 aerofoils are fixedly clamped; Two binder oil cylinder 2 workpiece pressings 9; Resilience this moment checkout gear 4 stretches out and withstands on the surface of the work, drives leading screw screw mechanism 6 driven rotary workbench 3 by servomotor 7 then and rotates around bearing pin 8, is converted into the anglec of rotation according to leading screw rotation transmission stroke; When reaching the angle initialization value; Rotary table 3 stops operating (as shown in Figure 2), and the binder oil cylinder 2 on the rotary table 3 unclamps (the binder oil cylinder 2 on the stationary work-table 1 still clamps with workpiece clamping mold 5) with workpiece clamping mold 5, and resilience appears in workpiece 9; Read roller because the length of workpiece 9 resiliences withdrawal from linear displacement transducer; Be converted into the spring back angle of workpiece 9, with the binder oil cylinder on the rotary table 32 and workpiece clamping mold 5 workpiece pressing 9 once more, servomotor 7 drives leading screw screw mechanisms 6 rotates rotary table 3 once more then; This time anglec of rotation will be a bit larger tham the spring back angle value, reaches the required angle of instructions for use after making the workpiece bending.
Like Fig. 3, shown in Figure 4, also can carry out the bending at a plurality of positions to a workpiece 9.
