Description

Assembled return bend moulding-die

Technical Field

The utility model belongs to equipment pipeline shaping field relates to an assembled return bend moulding-die.

Background

The existing equipment is generally formed by a manual pipe bender, the efficiency is low, the appearance of a bent pipe is inconsistent, the appearance of the same pipe group of the same equipment is inconsistent, and the appearance does not reach the standard.

When the continuous casting equipment has more water cooling pipelines at the plate blank fan-shaped section and large batch, the pipe bending is carried out manually, the efficiency is low, and the consistency of the same batch of pipes is poor. In order to ensure the appearance quality of the water-cooling piping, the same batch of pipes are required. Different batches of the products have different requirements and need different bending radii, namely the universality of the products also needs to be considered.

Description of reference numerals: the device comprises a lower die base 1, a lower die 2, a workpiece 3, a pressing plate 4, an upper die base 5, an upper die 6, a pressing and elastic guide rod 7, an adjusting base plate 8, an end face stop block 9 and a T-shaped bolt 10.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 5, the utility model discloses an assembled return bend moulding-die includes die holder 1, lower mould 2, work piece 3, clamp plate 4, upper die base 5, go up mould 6, pressure bullet guide bar 7, adjusting shim plate 8, terminal surface dog 9, T type bolt 10, two lower moulds 2 pass through T type bolt 10 to be fixed on die holder 1, set up upper die base 5 on lower mould 2, go up mould 6 on 5 lower part fixed connection of upper die base, 5 both sides of upper die base set up pressure bullet guide arm 7, pressure bullet guide arm 7 passes through adjusting shim plate 8 and is connected with clamp plate 4. The utility model discloses an go up the mould 6 center and be located the perpendicular line of 2 center connection lines of two lower moulds, the centre of sphere of going up mould 6 hemisphere promptly is located the centre of a circle connecting wire perpendicular line of 2 two hemispheres of two lower moulds, ensures like this that the atress of push down formula both sides is even, improves product quality. The pressing and elastic guide rods 7 are symmetrically arranged on the central surfaces of the two lower dies 2, so that when the pressing plates 4 press the workpieces 3 on the two sides, namely, the distance between the pressing points is equal, and the moving distance of the pressing plates 4 on the two sides is the same in the deformation process.

As shown in fig. 1 to 3, an end surface stopper 9 is disposed on one side of the lower die holder 1 and the upper die holder 5, and the end surface stopper 9 is used for stopping the workpiece 3 during machining, so that during machining, one side of the workpiece 3 is directly abutted on the end surface stopper 9, thereby increasing the machining speed.

The utility model discloses an go up mould 6, lower mould 2 can be hemisphere, ellipsoid isotructure, according to the processing requirement and the different shape or size of selectable.

The utility model discloses an assembled return bend moulding-die is particularly suitable for the diameter and is less than 30 cm's path pipe, and under mass production's the condition, the subassembly can not warp, and the product appearance is unanimous when having ensured mass production to ensure product quality. The utility model discloses outside actuating mechanism is connected to upper die base 5, and outside actuating mechanism can be for pneumatic cylinder, driving motor etc. through reciprocating of control mechanism control upper die base 5.

The utility model discloses a device during operation, as shown in fig. 1, confirm 2 diameters of lower mould, 2 intervals of lower mould, go up mould adjusting shim plate 8 thickness according to 3 shaping radii of work piece earlier. The distance between the lower dies 2 is adjusted and fastened by T-shaped bolts 10 on the T-shaped grooves of the lower die holder 1. The thickness of the upper die adjusting base plate 8 is determined according to the forming height difference and the rebound quantity of the workpiece 3. After the adjustment is completed, the batch of workpieces 3 are placed into the semicircular groove of the lower die 2, and the left end of the batch of workpieces is aligned with the end face stop block 9. When in forming, the upper die 6 moves downwards, the pressing plate 4 presses the workpiece 3 to be fixed under the action of the elasticity of the pressure spring of the elastic pressing guide rod 7, the pressing plate moves downwards until the upper die 2 presses the workpiece 3, the forming starts, as shown in fig. 2, when the forming is finished, the pressing plate 4 is compacted, the forming is finished, and the formed workpiece 3 can be taken out after the upper die base 5 moves upwards.
