The utility model is described in further detail below in conjunction with example figure:
Fig. 1 is structural representation of the present utility model;
Among the figure, the master cylinder of 1. boring a hole; 2. perforation side cylinder; 3. perforation frame; 4. moving crosshead; 5. perforation push and pull system; 6. decide the pin nut; 7. perforation connecting rod; 8. master cylinder; 9. main plunger; 10. the back rest; 11. pecker contiguous block; 12. perforation needle stand; 13. guiding needle stand; 14. pecker; 15. pressure ram.
The specific embodiment
This external punch block mechanism, it adopts the punch block mechanism of external prestressed frame formula structure, comprise perforation frame, moving crosshead, perforation master cylinder, perforation side cylinder and perforation push and pull system part, the perforation frame is connected with the extruder back rest, the perforation master cylinder is connected with moving crosshead with perforation side cylinder, perforation push and pull system end is installed on the moving crosshead, and front end passes parts such as master cylinder, main plunger, pressure ram.Punch block mechanism can be decided pin nut realization machinery by adjusting and decide pin, and the adjustable footpath strip length of adjusting.The perforation frame is prestressed structure, and punch block mechanism comprises a master cylinder, two side cylinders totally three drive oil cylinders, driven by two side cylinders during its middle punch backhaul.
As shown in Figure 1, adopt the punch block mechanism of external prestressed frame formula structure to be installed in the extruder back rest 10 rear portions, extruder is that known device is not described in detail here.The perforation master cylinder 1 of punch block mechanism, perforation side cylinder 2 are fixedlyed connected with moving crosshead 4 one ends by perforation frame 3 respectively, and moving crosshead 4 other ends link to each other with perforation push and pull system 5.Perforation push and pull system 5 comprise decide pin nut 6, core pin 7, pecker contiguous block 11, perforation needle stand 12, guiding needle stand 13, pecker 14 connects and composes successively, core pin 7 adopts the connected mode of floating with pecker contiguous block 11, and unsteady connection is that industry known technology is not described in detail here.Perforation push and pull system 5 is passed master cylinder 8, main plunger 9 and pressure ram 15.Master cylinder 8 is fixed on the extruder back rest 10, and perforation frame 3 also is connected with the extruder back rest 10, and main plunger 9 is in 8 li slips of master cylinder, and main plunger 9 is fixedlyed connected with pressure ram 15.Master cylinder 8 is the master cylinder of extruder.
Piercing process is divided into servo-actuated pin extrusion process and locking pin extrusion process, they all are known technologies, the seamless tubular goods inner surface quality of locking pin technology extruding is good, but it is not high that present locking pin is decided the pin precision, cause inner surface quality relatively poor, after adopting external punch block mechanism of the present invention, the machinery of this mechanism is decided pin and can be improved locking pin and decide the pin precision, improves the internal surface of pipe quality.
In the servo-actuated pin extrusion process, perforation master cylinder 1 and the side cylinder 2 of boring a hole drive moving crossheads 4 drive perforation push and pull system 5 and move forward, and the master cylinder of hydraulic oil injection simultaneously 8 drives main plungers 9 and pressure ram 15 together moves forward extrusion billet.In the locking pin extrusion process, perforation master cylinder 1 and perforation side cylinder 2 at first drive moving crosshead 4 drive perforation push and pull system 5 and move forward, and hold out against in master cylinder 8 rear ends until deciding pin nut 6, afterwards, master cylinder 8 drives main plunger 9 and pressure ram 15 moves forward, and extrusion billet is made extruded product.After finishing corresponding extrusion process, drive moving crosshead 4 by perforation side cylinder 2,5 backhauls arrive the perforation system initial position with the perforation push and pull system to drive perforation master cylinder 1.The external punch block mechanism of the utility model design both can be applied to servo-actuated pin extrusion process, also adapted to and the locking pin extrusion process, and its order ground all is in order to improve the locking pin positioning accuracy.Described punch block mechanism can be decided pin nut 6 realization machineries by adjusting and decide pin, and the adjustable footpath strip length of adjusting.
During punch block mechanism work, a perforation master cylinder and two perforation side cylinders drive moving crosshead and move forward, and moving crosshead drives coupled core pin system and advances, and finishes corresponding extrusion process.When carrying out servo-actuated pin extrusion process, the perforation push and pull system together moves forward with the pressure ram of master cylinder under the driving of punch block mechanism; When carrying out the locking pin extrusion process, the core pin system advances, and makes to decide the pin nut and hold out against in the master cylinder rear end, realizes that machinery decide pin, and master cylinder, main plunger driving pressure ram extruded aluminium ingot blank are finished the locking pin extrusion process afterwards.During the perforation system backhaul, driven by two perforation side cylinders, drive moving crosshead and the backhaul of core pin system.
Adopted unsteady connected mode between the perforation perforation connecting rod 7 of push and pull system 5 and the pecker contiguous block 11, made in extrusion process, can be because of the concentricitys that make pecker 14 off-centre influence tubing that are connected between perforation connecting rod 7 and the pecker contiguous block 11.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
