Abstract

The utility model relates to a round pipe shaping die, which comprises two shaping dies which respectively comprise a die shank, an upper die plate, a lower die plate, a male die, a female die, a guide post and a guide sleeve. The round pipe shaping die is characterized in that the male die and the female die are both provided with a discharge apparatus; the female die forms a half circular arc shape which is concave inwards; the male dies of the two shaping dies are respectively an outwards convex circular arc-shaped male die and an inwards concave circular arc-shaped male die. Only the male dies are different in the two shaping dies, therefore, process duties for sheet shaping round pipes can be completed by using a set of die and changing the male dies. Drill holes replace punching holes. The work efficiency is improved.

Description

A kind of pipe finishing die

The utility model relates to a kind of finishing die, particularly a kind of pipe finishing die.

In filter industry, usually need a kind of tubular frame of filter element, intensive aperture is arranged on pipe.Adopt extrusion process to make needed pipe for a long time, hole on pipe with drilling technique, efficient is very low.Employing is punching processes aperture on sheet material, and the efficient height is made pipe but its key is the plate that how will bore the hole.

It can be the pipe finishing die of pipe with sheet forming that the purpose of this utility model provides a kind of.

Task of the present utility model is to realize like this, it comprises two finishing dies, die shank is arranged respectively, cope match-plate pattern, lower bolster, punch, die and guide pillar, guide pin bushing, it is characterized in that: be equipped with discharger on the punch of two finishing dies and the die, the discharger of punch is connected punch by screw with fixed head, between punch and fixed head, be provided with elastic component, the polished rod of screw partly places in the hole of elastic component, the discharger of die is to be provided with the hole on die and lower bolster, push rod places in the hole, the termination of push rod contacts with elastic component, the die of two finishing dies is the semicircular arc of an indent, the punch of two finishing dies is respectively circular arc punch and the cambered outwards circular arc punch that concaves, the arc diameter of the circular arc punch that concaves is identical with the arc diameter of die, and the arc diameter of cambered outwards circular arc punch equals the poor of the arc diameter of die and two formed thereby sheet thicknesses.

The utility model is the mould of pipe owing to providing sheet forming, has realized replacing bore process with punching, has improved production efficiency greatly.

Fig. 1 is the pipe finishing die structural representation of cambered outwards circular arc for the utility model punch.

Fig. 2 is the left side view of Fig. 1.

Fig. 3 is the pipe finishing die structural representation of the circular arc that concaves for the utility model punch.

Drawing explanation: 1. die shank 2. fixed heads 3. discharging screws 4. rubber blankets 5. cope match-plate patterns 6. punch 7. dies 8. lower bolsters 9. push rods 10. guide pin bushings 11. guide pillars 12. punch 13. unloading block

In conjunction with above accompanying drawing embodiment of the present utility model is elaborated.Cope match-plate pattern 5 is provided with the die shank 1 that is connected with punch press, below cope match-plate pattern 5, be provided with punch 12 or punch 6, punch is fixed on the lower surface of cope match-plate pattern by screw and fixed head 2, both sides with punch below fixed head 2 are provided with rubber blanket 4, the front end screw thread of discharging screw 3 and tailing screw flight respectively with fixed head 2 and unloading block 13 on screwed hole match, the polished rod of discharging screw 3 partly places in the hole of rubber blanket 4, die 7 is fixed on the lower bolster 8, shedding mechanism on the die is that two push rods 9 place in the hole of hole in the arc groove of die 7 and lower bolster 8, the below of lower bolster 8 is provided with two metallic plates, rubber blanket is arranged between the metallic plate, screwed hole by screw and two metallic plates matches, be fixed in the screwed hole of lower bolster, the lower surface of push rod 9 contacts with metallic plate.Guide pillar 11 is fixed in the hole of the guide pin bushing 10 that is slidingly fitted in cope match-plate pattern 5 on the lower bolster 8.The utility model pipe finishing die is made up of two finishing dies, these two finishing dies are except that the die difference, other parts are identical, therefore, an available mold can be finished by changing punch, with punch 12 sheet forming is gone out semicircle earlier, then with punch 6 pipe that can be shaped, when utilizing punch 6 to carry out the pipe shaping, also can on the semicircle material that is formed of die, put a cylinder and make fuse.

Claims
