Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 6.

A bending forming die which is high in forming efficiency of Z-shaped workpieces and not prone to defective products.

Specific embodiments of the invention: the die is provided with a forming device 1, the forming device 1 comprises a forming seat 2 and two positioning seats 3, the forming seat 2 is arranged between the two positioning seats 3, the two positioning seats 3 are used for positioning a workpiece 101, and the forming seat 2 rotates and drives the workpiece 101 to be bent into a Z shape; the positioning seat 3 is provided with a positioning channel 4, the forming seat 2 is provided with a forming channel 5, and the two positioning channels 4 and the forming channel 5 are corresponding and are arranged on the same straight line.

When a workpiece 101 is machined and formed, the straight rod-shaped workpiece 101 is conveyed to a die, the workpiece 101 sequentially extends into one positioning seat 3, a forming seat 2 and the other positioning seat 3, at the moment, the workpiece 101 extends into two positioning channels 4 and a forming channel 5, the workpiece 101 is fixed by the two positioning seats 3, and then the forming seat 2 rotates and drives the middle part of the workpiece 101 to rotate, so that the two sides of the workpiece 101 are simultaneously bent, and the Z-shaped workpiece 101 is machined and formed; finally, the bent and formed workpiece 101 is pushed down to be separated from the die, and the forming seat 2 is reset, so that the next workpiece 101 can be conveniently processed; by the arrangement, the Z-shaped workpiece 101 can be formed through one process, so that the processing efficiency of the workpiece 101 is greatly improved; because work piece 101 one process shaping, work piece 101 is difficult for appearing work piece 101 location unstability, take place the skew scheduling problem, and then makes the processing of work piece 101 more stable, and the yields is higher.

Open the slide opening 6 that has the intercommunication each other on the mould and hold chamber 7, hold and be equipped with gear 8 in the chamber 7, be equipped with rack 9 on the mould, rack 9 stretches into slide opening 6 and rack 9 and gear 8 meshing, and rack 9 slides and drives gear 8 and rotate in slide opening 6, and the one end of shaping seat 2 inserts the mould and is connected with gear 8.

When the die bends the workpiece 101, a hydraulic cylinder matched with the die is arranged outside the die, the hydraulic cylinder is connected with the rack 9 and drives the rack 9 to slide in the sliding hole 6 in a reciprocating manner, so that the rack 9 drives the gear 8 to rotate in the accommodating cavity 7 in a reciprocating manner, and the gear 8 drives the forming seat 2 to rotate, and further the bending forming of the workpiece 101 is realized; the rack 9 moves downwards, so that the gear 8 rotates and drives the forming seat 2 to rotate, the workpiece 101 is bent and formed, the formed workpiece 101 is pushed down to the die, then the rack 9 moves upwards, the gear 8 drives the forming seat 2 to reset, and the next workpiece 101 is conveniently processed.

The forming base 2 is provided with a material ejecting hole 10 communicated with the forming channel 5, the material ejecting hole 10 penetrates through the die, the material ejecting hole 10 penetrates through the forming base 2, the die is provided with a cylinder 11, a thimble 12 stretching into the material ejecting hole 10 is arranged on the cylinder 11, and the cylinder 11 pushes the thimble 12 to stretch into the forming channel 5.

When a workpiece 101 needs to be pushed down to a die after being bent and formed, the air cylinder 11 is started and drives the ejector pin 12 to extend into the forming channel 5, the ejector pin 12 props up the workpiece 101 in the forming channel 5 until the workpiece 101 is ejected out of the forming channel 5, blanking of the workpiece 101 is finished, and the forming base 2 is reset; after the blanking of the workpiece 101 is completed, the thimble 12 is reset, so that the machining of the workpiece 101 is not influenced by the thimble 12; due to the arrangement, the blanking of the workpiece 101 is more convenient and labor-saving, and the processing efficiency of the workpiece 101 is also improved.

Magnets 13 are embedded in the two positioning channels 4, and the end faces of the magnets 13 are flush with the inner walls of the positioning channels 4.

When the straight rod-shaped workpiece 101 is pushed into the die, the workpiece 101 is made of a material which is in adsorption connection with the magnets 13, and the magnets 13 in the two positioning channels 4 adsorb the workpiece 101, so that the workpiece 101 is positioned, the workpiece 101 is not easy to shift when the workpiece 101 is bent, and the high yield of the workpiece 101 is ensured; the end face of the magnet 13 is flush with the inner wall of the positioning passage 4, so that the magnet 13 is not easy to clamp the workpiece 101 during transportation.

Positioning seat 3 all includes spliced pole 14, spliced pole 14 insert in the mould and rotate with the mould and be connected, be equipped with limiting plate 15 on spliced pole 14's the lateral wall, it has the cross-section to be fan-shaped and with positioning seat 3 complex activity groove 16 to open on the mould, limiting plate 15 stretches into in activity groove 16 and in the rotation of activity groove 16, limiting plate 15 contradicts with the inner wall of activity groove 16 one side, is equipped with spring 17 in the activity groove 16, and spring 17's one end is contradicted with limiting plate 15, and spring 17's the other end is fixed in on the inner wall of activity groove 16 opposite side, the rotation direction of two positioning seats 3 is the same, and the rotation direction of positioning seat 3 is opposite with the rotation direction of shaping seat 2.

Shaping seat 2 rotates and makes work piece 101 bent, thereby make work piece 101's both sides end also take place the skew and then extrude two positioning seats 3 respectively, and then positioning seat 3 takes place to rotate, limiting plate 15 takes place to rotate and extrudes spring 17 in activity inslot 16 promptly, set up like this, make work piece 101 bent the shaping back, work piece 101 makes positioning seat 3 take place to rotate, under spring 17's elastic force, certain elasticity pretightning force has between positioning seat 3 and the work piece 101, thereby make work piece 101 bend behind the shaping difficult by two positioning seats 3 and one shaping seat 2 card die, and then make thimble 12 more light when promoting work piece 101 unloading, it is convenient.
