Description
The utility model relates to the machining equipment of metal forming, and specifically the hammer in the forging equipment is the die hammer that utilizes full hydraulic drive furtherly.
Domestic existing die hammer, see from type of drive to be divided into two kinds: a kind of is steam drop hammer, and a kind of is the liquid gas die hammer that steam hammer forms after transforming, and lathe bed structure is column, anvil block is split type.Steam drop hammer, promptly with the hammer of steam as driving medium, its working cylinder rod chamber, rodless cavity are steam chest.During the rodless cavity admission, rod chamber is connected atmosphere, and slide block is realized quick descending motion under the effect of rodless cavity air pressure and deadweight; During the rod chamber admission, rodless cavity is connected atmosphere, slide block backhaul.Because loss abundant residues pressure energy and heat energy during this hammer working cylinder steam discharge, thereby energy utilization rate is extremely low.Liquid gas die hammer, promptly with the hammer of hydraulic pressure, air pressure associating transmission, a certain amount of gas of filling in its working cylinder rodless cavity, when hydraulic oil entered rod chamber, the gas in the rodless cavity was compressed, and slide block is forced to; When rod chamber and oil return opening connection oil extraction, the expansion of compressed gas in the rodless cavity, slide block is realized quick descending motion under the effect of expanding gas and deadweight.This hammer must can send after strike finishes owing to returned signal, thereby has shortcomings such as vexed mould time length, resilience double hit, has the shortcoming of leaking easily simultaneously.Domestic existing die hammer lathe bed all adopts column, anvil block split-type structural, and column is fixed on the anvil block by turnbuckle.
The purpose of this utility model provides the complete hydraulic die forging hammer of a kind of resilience double hit simple in structure, safe and reliable, energy-efficient, no, no vexed mould phenomenon.
Technical solution of the present utility model is: a kind of complete hydraulic die forging hammer, it is characterized in that: the whole lathe bed of a U-shaped is arranged, an all-hydraulic power head is arranged on it, all-hydraulic power head has a working cylinder, and working cylinder is with outer shell outward, and working cylinder connects workpiece, the annular hydraulic fluid passage is arranged between working cylinder, the outer shell, annular hydraulic fluid passage upper end is connected with the pressure hydraulic fluid port, and lower end and working cylinder rod chamber are connected, and working cylinder, outer shell are connected with fuel tank through integrated package.
Fuel tank described in the utility model is sleeved on outside the outer shell, and is fixed in the outer shell upper end by integrated package.The workpiece that working cylinder connected comprises: hammer stem is housed in the working cylinder, and the hammer stem lower end is connected with slide block.Hammer stem is divided into rod chamber and rodless cavity with working cylinder inwall cavity, and hammer stem top epicoele is a rodless cavity.Whole lathe bed one side of U-shaped is equipped with pneumatic safety pin.Integrated package is installed on the fuel tank, and fixedly outer shell, working cylinder, control valve is housed in the integrated package, and connects by oil circuit and working cylinder rod chamber, rodless cavity, oil pump, fuel tank, accumulator is housed on the integrated package, also can adopts other suitable specific constructive form certainly.
Advantage of the present utility model: because this hammer adopts full hydraulic drive, the oil extraction pressure loss of energy of working cylinder is few, does not have heat-energy losses, thereby the transmission efficiency height, overcomes the high shortcoming of steam hammer energy consumption.Because the working cylinder rod chamber passes to pressure oil all the time, hit the backhaul immediately of back tup, thereby it is long to have overcome the vexed mould time of hydraulic die forging hammer, the shortcoming of resilience double hit.Owing to adopted all-hydraulic power head, operating pressure is higher, thereby make slide block in short stroke, be quickened and gather huge kinetic energy, high-frequency is forged become possibility, overcome liquid pneumatic hammer, steam hammer because the rodless cavity working medium pressure is not high, the slide block accelerating travel is longer, the larger-size shortcoming of forging hammer attach structure.Owing to adopted U-shaped integral bed body structure and safety pin structure, rigidity, the security of percussion system are strengthened greatly, and operating accuracy is guaranteed.Overcome split type lathe bed because the shortcoming of rigidity effects complete machine operating accuracy, reliability and the security that connects.This hammer is simple in structure, safe and reliable, energy-efficient, excellent performance.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the structural representation of a kind of complete hydraulic die forging hammer of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.In this embodiment, the whole lathe bed 01 of a U-shaped is arranged, an all-hydraulic power head is arranged on it, all-hydraulic power head has a working cylinder 06, the working cylinder 06 outer outer shell 05 that is with, and working cylinder 06 connects workpiece, between working cylinder 06, the outer shell 05 the annular hydraulic fluid passage is arranged, annular hydraulic fluid passage upper end is connected with the pressure hydraulic fluid port, and lower end and working cylinder 06 rod chamber are connected, and working cylinder 06, outer shell 05 are connected with fuel tank 04 through integrated package 07.Described fuel tank 04 is sleeved on outside the outer shell 05, and is fixed in outer shell 05 upper end by integrated package 07.The workpiece that working cylinder 06 is connected comprises: hammer stem 03 is housed in the working cylinder 06, and hammer stem 03 lower end is connected with slide block 02.Hammer stem 03 is divided into rod chamber and rodless cavity with working cylinder 06 inwall cavity, and hammer stem 03 top epicoele is a rodless cavity.Whole lathe bed 01 1 sides of U-shaped are equipped with pneumatic safety pin 13.Integrated package 07 is installed on the fuel tank 04, and fixedly outer shell 05, working cylinder 06, in the integrated package 07 control valve is housed, and connects by oil circuit and working cylinder 06 rod chamber, rodless cavity, oil pump, fuel tank 04, and accumulator 09 is housed on the integrated package 07.
The operation principle of the foregoing description is: accumulator 09 is oil-filled when reaching certain pressure, and slide block 02 is back to the upper limit, is in the strike state of waiting for.This moment valve 14 be in electricity condition, safety pin 13 is in extended position, pins slide block and prevents that mistake from hitting.During strike, valve 14 dead electricity, after safety pin 13 withdrawed from, strike valve 08 got electric, and working cylinder 06 rodless cavity and accumulator 09 pressure hydraulic fluid port are connected, and the circular passage and working cylinder 06 rod chamber that pass through working cylinder 06 outside are connected, realize differential, so the pressure oil that rod chamber pressure oil, pump 12 are got, accumulator 09 pressure oil together enter rodless cavity, add the deadweight of slide block 02, realized the quick strike action of slide block 02.
During backhaul, hit valve 08 dead electricity, working cylinder 06 rodless cavity and fuel tank 04 are connected decompression, owing to rod chamber communicates with accumulator 09 pressure oil by the circular passage all the time, thereby under the pressure oil effect, slide block 02 quick return.
When still not hitting above a setting-up time, valve 14 is electricly automatic, and safety pin 13 stretches out, and slide block 02 is in locking-in state.
Present embodiment is equipped with hydraulic means when practical application, whole hydraulic means is realized the oil-filled and off-load of 12 pairs of accumulators 09 of oil pump automatically by special service valve 10.
Among the figure 11 is motor; 15 is mould; 16 is die holder.
