The bending mechanism for manufacturing the U-shaped titanium alloy plate with the oblique angle comprises an upper mould part and a lower mould part, wherein the upper mould part comprises a mould handle, an upper mould base and a convex mould; the convex mould is fixed below the upper mould base; the mould handle is installed on the upper mould base through interference fit; the lower mould part comprises a lower mould insert, a fixing plate and a lower mould base; the lower mould insert is fixedly installed on the fixing plate through bolts; the fixing plate is installed on the lower mould base; and two circular concave moulds are arranged on the lower part of the lower mould insert. The bending mechanism for manufacturing the U-shaped titanium alloy plate with the oblique angle simplifies machining processes of a U-shaped component, is easy to operate, ensures the machining quality of the workpiece and the working efficiency and greatly reduces the machining cost of a component.
Description
Technical field
The utility model relates to a kind of bending mechanism, relates in particular to a kind ofly to have U-shaped titanium alloy sheet bending mechanism of rake angle for making, belongs to the mechanical bend processing technique field.
Background technology
During machining was produced, bending machining was the wider a kind of manufacturing procedure of range of application, with regard to bending machining, the bending machining of simple shape and the bending machining of complicated shape is arranged.For the fairly simple curved workpieces of shape, such as U-shaped spare and V-arrangement spare, can be shaped by first order buckling.But the U-shaped part shape that process this moment does not have certain rake angle, thereby generally needs twice or repeatedly bending, just can shape.Repeatedly bending machining no doubt makes that manufacturing procedure is loaded down with trivial details, and the operating personnel that need are many, and the process equipment investment is high, and needs repeatedly to locate in the processing, complicated operation, and workpiece quality and working (machining) efficiency are difficult to guarantee, directly cause the cost of processing work to increase.
The utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model discloses U-shaped the titanium alloy sheet bending mechanism that a profit has rake angle.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of U-shaped titanium alloy sheet bending mechanism for making band row rake angle, comprise upper mold portion and lower mold portion, and upper mold portion comprises die shank, upper bolster and punch; Punch be fixed on upper bolster below, die shank by interference fit be installed in upper bolster above; Lower mold portion comprises that counterdie is inserted, fixed head and die shoe; Counterdie is inserted and is installed on the fixed head by bolting, and fixing plate device is on die shoe; Circular die is two, and two circular dies are placed on the below that counterdie is inserted.
The inside that counterdie is inserted has circular through hole, and through hole and circular die are complementary.
Back-moving spring one end is enclosed within on counterdie inserts, and the other end is fixed on the circular die.
The utility model has been simplified U-shaped spare manufacturing procedure, and is simple to operate, guaranteed workpiece crudy and operating efficiency, greatly reduces the processing cost of part.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is matched moulds processing structure schematic diagram of the present utility model.
Status architecture schematic diagram when Fig. 3 is the utility model discharging.
Among the figure: 30, die shank, 31, upper bolster; 32, punch; 33, counterdie is inserted; 34, back-moving spring; 35, bolt; 36, fixed head; 37, die shoe; 38, baffle plate 39, circular die; 40, location-plate; 41, bolt; 42, drip molding.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises upper mold portion and lower mold portion.Upper mold portion comprises die shank 30, upper bolster 31 and die 32; Punch 32 be fixed on upper bolster 31 below; Die shank 30 by interference fit be installed in upper bolster 31 above.
Lower mold portion comprises that counterdie inserts 33, fixed head 36 and die shoe 37.Counterdie is inserted and 33 is fixedly mounted on the fixed head 36 by bolt 41, and fixed head 36 devices are on die shoe 37.Circular die 39 is two, and two circular dies 39 are placed on insert 33 below of counterdie.Location-plate 40 and back-moving spring 34 are two; Two location-plates 40 and two back-moving spring 34 effects are to utilize its elasticity that circular die 39 is withdrawn into initial position after finishing workpiece.
Punch contacts with the upper surface of workpiece when finishing stretching, and the lower surface of workpiece contacts with circular die, between punch and the circular die certain clearance is arranged in the horizontal direction.
The angle that circular die can rotate is just accepted the workpiece that punch transmits smoothly, does not abrade workpiece during discharging.
The course of work of present embodiment is as follows:
Shown in Fig. 2～3, upper bolster 31 moves downward drive punch 32 and moves downward, depressing blank at the effect lower punch 32 of downforce inserts by counterdie and 33 will descend part to bend to U-shaped, upper bolster 31 continues to move downward, force circular die 39 to rotate, shape behind circular die 39 matched moulds is corresponding with the outer shape of punch 32, and this moment, blank bent to the U-shaped workpiece that has rake angle under the effect of mold clamping force.
After the U-shaped workpiece of band row rake angle machines, upper bolster 31 begins to rise, U-shaped of this moment tightly be wrapped in that thereby workpiece rises with punch on the punch 32, circular die itself returns to the preceding original initial position of processing gradually because the spring tightening force makes, this moment, punch 32 broke away from circular die 39 smoothly together with the workpiece after machining, after upper bolster 31 stops to move upward, under the effect of external force, unload the processing that workpiece begins next workpiece, circulation and so forth, once finish U-shaped the processing that has rake angle with simple operation, improve quality and the precision of processing work, greatly reduced production cost.
Above-mentioned embodiment is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in the technical solution of the utility model scope, remodeling, interpolation or replacement also all belong to protection domain of the present utility model.
