CN2710791Y - Double cylinder hydraulic forging hammer - Google Patents

Abstract

The utility model discloses a double cylinder hydraulic forging hammer. Two one way hydraulic rams 3 connected in parallel are respectively arranged vertically in the two vertical posts of the base of a machine frame 7; the oil feeding and the oil returning of the two hydraulic rams 3 are adopted the same oil way; the hand-operated direction valve is used for controlling the operation, the hydraulic oil can simultaneously be drove into the hydraulic ram 3 by wrenching the hand-operated direction valve to make a piston-rod 8 lift to peak the ram 1 to a prescribed height; wrenching the hand-operated direction valve for another time to instruct the offloading refluxing of the oil way, the piston-rod 8 falls, and the hammer can be proceeded on the workpieces workblank using the own weight of the ram 1. The construction cost is lower than the construction cost of pneumatic hammers of the same specifications, the noise pollution is decreased, and the power consumption is only about 10% of the power consumption of the pneumatic hammers.

Description

Twin-tub liquid forging hammer

Technical field

The utility model belongs to metal forming machinery, relates to forging hammer equipment particularly.

Background technology

Existing forging hammer equipment generally adopts the pneumatic hammer structure, its transmission of power medium is an air, though can finish the requirement that forges of general workpiece, but the operation effort, consumption of power is many, because pneumatic hammer manufacturing process complexity, cost is higher, the intake and exhaust noise is big, has serious noise pollution, and is unfavorable to the working environment influence.

Summary of the invention

The purpose of this utility model just provides and a kind ofly can reduce noise pollution, reduces power consumption and cost, new swage easy and simple to handle.

Task of the present utility model is finished like this: design a kind of twin-tub liquid forging hammer, form by tup, tup guide rail, hydraulic jack, last anvil piece, following anvil piece, hammer anvil, frame, hydraulic power part etc., adopt in two root posts of two unidirectional hydraulic jacks difference vertical means in parallel on gantry base, the Hydraulic Station and the reversal valve of hydraulic power part link up by oil circuit and hydraulic jack.Same oil circuit is adopted in the oil-feed of two hydraulic jacks, oil return.Reversal valve adopts hand-operated direction valve, is used for control operation.

Compare with traditional pneumatic hammer, characteristics of the present utility model are that noise is low, and power consumption is few, and are low, flexible to operation with tonnage pneumatic hammer cost, reached predeterminated target preferably.

Description of drawings

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is hydraulic jack 3 structure charts of the present utility model.

Among the figure: 1--tup, 2--tup guide rail, 3--hydraulic jack, the last anvil piece of 4--, anvil piece under the 5--, 6--hammer anvil, 7--frame, 8--piston rod, 9--oil pipe.

The specific embodiment

The utility model overall structure as shown in Figure 1, tup 1 is contained on the tup guide rail 2 of frame 7 centres, hammer anvil 6 is housed on the base of frame 7, anvil piece 5 under the device on the hammer anvil 6, two unidirectional hydraulic jacks 3 in parallel are installed in respectively on the base of frame 7 in two root posts, the oil-feed of two cylinders, oil return be all by oil pipe 9, its mounting structure form such as Fig. 2, and the top of piston rod 8 contacts with the gripper shoe lower end of tup 1.Pull hand-operated direction valve during work, the hydraulic oil of instruction Hydraulic Station is squeezed in two hydraulic jacks 3 simultaneously, and the piston rod 8 of two hydraulic jacks 3 is risen simultaneously, with tup 1 along tup guide rail 2 jack-up that makes progress.When tup 1 is raised to specified altitude assignment, pull the unloading of hand-operated direction valve instruction oil circuit again, make hydraulic oil be back to Hydraulic Station fast, the piston rod 8 of hydraulic jack 3 falls thereupon, the tup 1 that loses support falls naturally, utilizes deadweight to be forged by the workpiece blank on 4 pairs of following anvil pieces 5 of last anvil piece.As required, can also be by pulling the position of hand-operated direction valve, the sealing of instruction hydraulic oil is in hydraulic jack 3, make tup 1 be anchored in the specified altitude assignment of the tup guide rail 2 on the frame 7, pull hand-operated direction valve by the operation requirement again and handle tup 1 rising or decline, hand-operated direction valve plays the effect of gauge tap.

Design and produce according to above-mentioned, prove that the utility model is lower, easy to install than same specification pneumatic hammer cost, reduced noise pollution, improved working environment, consumption of power only is about 10% of a pneumatic hammer, is applicable to the processing that forges of metal works blank.

Claims (3)

1, a kind of twin-tub liquid forging hammer, form by tup (1), tup guide rail (2), hydraulic jack (3), last anvil piece (4), following anvil piece (5), hammer anvil (6), frame (7), hydraulic power part etc., it is characterized in that adopting in the column of two unidirectional hydraulic jacks in parallel (3) difference vertical means on frame (7) base, the Hydraulic Station and the reversal valve of hydraulic power part link up by oil circuit and hydraulic jack (3).

2,, it is characterized in that said two hydraulic jacks (3) adopt same oil circuit oil-feed, oil return according to the described twin-tub liquid of claim 1 forging hammer.
