Abstract
The utility model discloses a stamping mechanism for extruding pipe fitting heads. The mechanism comprises a rack, an upper stamping head and a lower stamping head which fit with each other in the motion are arranged on the rack, and the contact surfaces of the upper stamping head and the lower stamping head are respectively divided into initial stamping zones and final stamping zones. The surfaces of the initial stamping zones of the upper stamping head and the lower stamping head are wavy and matched in the shape. The surfaces of the final stamping zones of the upper stamping head and the lower stamping head are two grooves of semi-circular cross sections, and the hollow parts of the grooves are opposite. The stamping mechanism has high processing efficiency. Force is uniformly applied on the periphery of the pipe fitting heads by stamping in two directions.
Description
Technical field
The utility model relates to the metalworking technology field, relates in particular to a kind of press that is used to push the pipe fitting termination.
Background technology
In the prior art, the processing of copper pipe needs to stamp out through hole at the axis place of copper ingot earlier, and the mould that diminishes gradually by internal diameter successively of drawing copper ingot with holes makes copper pipe be tapered, until the caliber that obtains being scheduled to then.
In the drawing copper pipe,, stretch into, the termination of copper pipe need be pushed slightly, so that it can enter in the die hole smoothly for the ease of the termination of guiding copper pipe owing to all need the termination of copper pipe is stretched in the smaller mould of internal diameter at every turn.
All the artificial termination of copper pipe being pushed slightly in the prior art with instruments such as hammer, pincers, but the termination unbalance stress of such words copper pipe, efficient is not high yet.
Summary of the invention
The utility model provide a kind of termination that makes copper pipe stressed evenly and high being used to of working (machining) efficiency push the punching mechanism of pipe fitting termination.
A kind of punching mechanism that is used to push the pipe fitting termination, comprise frame, described frame is provided with last staking punch and the following staking punch that mutual motion cooperates, the described contact-making surface of going up staking punch and following staking punch is divided into just Stamping Area and whole Stamping Area separately, describedly go up the first Stamping Area of staking punch and the first Stamping Area surface of following staking punch is that waveform and shape are identical, described on the depression position that two cross sections are semicircular groove and groove of respectively doing for oneself, the whole Stamping Area surface of the whole Stamping Area of staking punch and following staking punch relative.
Adopt first Stamping Area in advance the termination of pipe fitting to be flattened the plate of waviness, utilize whole Stamping Area that corrugated plate is compressed again, make wide the dwindling of ripple of corrugated plate, stressed all around evenly by the punching press of both direction with the termination that guarantees pipe fitting.
Stability when using in order to keep punching mechanism, described staking punch down and frame are fixed, and the described staking punch of going up is connected with frame by telescoping mechanism.
Described telescoping mechanism is a hydraulic cylinder, and the motion of staking punch is gone up in convenient control.
Described punching mechanism is provided with the pedal that is hinged on the frame bottom, and this pedal is controlled the unlatching of telescoping mechanism by connecting rod or closed, the motion that staking punch is gone up in convenient control according to actual needs.

Fig. 2 is the structural representation that the utility model is used to push the another kind of user mode of punching mechanism of pipe fitting termination;
Fig. 3 is the pipe fitting termination profile after the utility model is used to push the punching mechanism Stamping Area punching press just of pipe fitting termination;
Fig. 4 is the pipe fitting termination profile after the utility model is used to push the whole Stamping Area punching press of punching mechanism of pipe fitting termination.
The specific embodiment
As shown in Figure 1, the utility model is used to push the punching mechanism of pipe fitting termination, comprises frame 1, and frame 1 is provided with last staking punch 4 and the following staking punch 5 that mutual motion cooperates, and following staking punch 5 is fixing with frame 1, and last staking punch 4 is connected with frame 1 by hydraulic cylinder.
In frame 1 bottom-hinged pedal 3 is arranged, this pedal 3 is controlled the unlatching of hydraulic cylinders by connecting rod 2 or is closed.
The contact-making surface of last staking punch 4 and following staking punch 5 is divided into just Stamping Area 6 and whole Stamping Area 7 separately, the first Stamping Area 6 of last staking punch 4 and first Stamping Area 6 surfaces of following staking punch 5 are that waveform and shape are identical, and the depression position that two cross sections are semicircular groove and groove of respectively doing for oneself, whole Stamping Area 7 surfaces of the whole Stamping Area 7 of last staking punch 4 and following staking punch 5 is relative.
When the punching mechanism that the utility model is used to push the pipe fitting termination specifically uses, the termination of copper pipe is put into down earlier in the first Stamping Area 6 of staking punch 5, step pedal 3 and open hydraulic cylinder, staking punch 4 moves downward under the promotion of hydraulic cylinder, the first Stamping Area 6 that makes staking punch 4 and the first Stamping Area 6 of following staking punch 5 are very near (as shown in Figure 2), make the termination of copper pipe flatten the plate (as shown in Figure 3) of waviness, unclamp pedal 3 and close hydraulic cylinder, finish first punching press copper pipe terminal.To put into down in the whole Stamping Area 7 of staking punch 5 through the termination of the copper pipe of first punching press again, the whole Stamping Area 7 of staking punch 5 under one end in contact of the copper pipe terminal of maintenance undulate, make it become one " wave that erects ", step pedal 3 and open hydraulic cylinder, staking punch 4 moves downward under the promotion of hydraulic cylinder, the whole Stamping Area 7 that makes staking punch 4 and the whole Stamping Area 7 of following staking punch 5 are very near (as shown in Figure 2), with corrugated plate compression, make wide the dwindling of ripple (as shown in Figure 4) of corrugated plate, unclamp pedal 3 and close hydraulic cylinder, finish whole punching press copper pipe terminal.
Claims (4)
