Abstract
The utility model provides an electrohydraulic hammer. The electrohydraulic hammer comprises a bracket, an oil and gas cylinder, a hammer rod, a hammer head and at least one height-increasing pad, wherein the hammer rod is vertically inserted into the bracket; the oil and gas cylinder is fixedly arranged on the bracket; the lower end of the oil and gas cylinder is connected with the upper end of the hammer rod; the lower end of the hammer rod is connected with the hammer head; and the height-increasing pad is arranged below the bracket in an overlapping mode. According to the eletrohydraulic hammer, the height-increasing pad is arranged below the bracket, so that the distance between the hammer head and a forge piece is increased on the premise of not increasing the height of the hammer rod, the blow energy of the hammer electrohydraulic hammer is increased, the problem that heaving forge pieces are forged and pressed by the electrohydraulic hammer difficultly under the condition of low cost is solved, and the physical properties of the forge pieces are greatly improved.
Description
Technical field
The utility model relates to a kind of forging equipment, relates in particular to a kind of electric liquid hammer.
Background technology
Forging hammer is to utilize impact energy to make metal produce the forging equipment of plastic deformation, former steaming, hollow forging hammer forges function take steam or compressed air as power to realize it, its efficient is low, energy consumption is high, environmental pollution is serious, the forging equipment of therefore mostly hammering into shape with the instead former steaming of electric liquid hammer, hollow forging now.The electricity liquid hammer is energy-efficient new science and technology product, it has mechanical, electrical, liquid integrated High Tech Products, the electricity liquid hammer mainly is for energy-conservation and environmental contamination reduction, has cancelled the boiler room (or air compression station) that the steaming that aims at the forging shop, hollow forging hammer dispose and has greatly reduced the pollution of environment and a large amount of freight volumes.The maximum blow energy of existing 4 electric liquid hammers is 150KJ, the weight of forging can reach about 2.8, the forging of tonnage have enough distances to make it to fall to reaching the purpose of forging and pressing forging between the tup of electric liquid hammer and the forging thereby need to make like this, and in the existing electric liquid hammer tup can on the distance carried be subjected to the restriction of electric liquid hammer height and oil gas cylinder performance, be difficult to make enough distances are arranged between tup and the forging, therefore for heavy weight forging, existing electric liquid hammer is difficult to realize successfully forging and pressing.
The utility model content
The utility model provides a kind of electric liquid hammer, to solve for heavy weight forging, because distance between tup and forging causes the forging and pressing hard problem not.
For solving the problems of the technologies described above, the utility model provides a kind of electric liquid hammer, described electric liquid hammer comprises support, oil gas cylinder, hammer stem, tup and at least one elevating pad, described hammer stem vertically is arranged in the described support, described oil gas cylinder is fixedly installed on the described support, the lower end of described oil gas cylinder is connected with the upper end of described hammer stem, and the lower end of described hammer stem is connected with described tup, and described at least one elevating pad overlaps under described support.
Further, described elevating pad is for watering steel part.
To between the 280mm, a plurality of elevating pads can be positioned under the support altitude range of described elevating pad in overlapping combination at 220mm.
Further, the height of described elevating pad is 250mm.
Compared with prior art, the utlity model has following beneficial effect:
By under support, increasing elevating pad, so that under the prerequisite that does not increase the hammer stem height, the distance of tup and forging has increased, thereby improved the blow energy of electric liquid hammer, solve the problem that electric liquid hammer is difficult to forge and press large weight forging under the condition cheaply, greatly improving the physical property of forging simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
The structural representation of the electric liquid hammer that Fig. 1 provides for the utility model embodiment.
In Fig. 1,
1: support; 2: oil gas cylinder; 3: hammer stem; 4: tup; 5: elevating pad; 6: forging.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the electric liquid hammer that the utility model proposes is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that accompanying drawing all adopts very the form of simplifying and all uses non-accurately ratio, only in order to convenient, the purpose of aid illustration the utility model embodiment lucidly.
Core concept of the present utility model is, a kind of electric liquid hammer is provided, described electric liquid hammer comprises support, oil gas cylinder, hammer stem, tup and at least one elevating pad, described hammer stem vertically is arranged in the described support, described oil gas cylinder is fixedly installed on the described support, the lower end of described oil gas cylinder is connected with the upper end of described hammer stem, the lower end of described hammer stem is connected with described tup, described at least one elevating pad overlaps under described support, by under support, increasing elevating pad, increased so that be arranged on the stroke of the hammer stem on the support, thereby drive tup the distance of itself and forging has also been increased, solving the problem that electric liquid hammer is difficult to forge and press large weight forging under the condition cheaply.
Please refer to Fig. 1, the structural representation of the electric liquid hammer that Fig. 1 provides for the utility model embodiment.
As shown in Figure 1, the utility model provides a kind of electric liquid hammer, described electric liquid hammer comprises support 1, oil gas cylinder 2, hammer stem 3, tup 4 and elevating pad 5, described hammer stem 3 vertically is arranged in the described support 1, described oil gas cylinder 2 is fixedly installed on the described support 1, the lower end of described oil gas cylinder 2 is connected with the upper end of described hammer stem 3, the lower end of described hammer stem 3 is connected with described tup 4, described elevating pad 5 is arranged at described support 1 time, by increase the elevating pad 5 of a high 250mm for 1 time at support, so that the stroke of hammer stem 3 when forging and pressing that is arranged on the support 1 increased, thereby driving tup 4 makes the distance of itself and forging 6 be increased to 1650mm from 1400mm, improved the blow energy of electric liquid hammer, solving the problem that electric liquid hammer is difficult to forge and press heavy weight forging 6 under the condition cheaply, and can guarantee that this heavy weight forging is also without quality problems when 2.8 tons of forging of forging and pressing.
Further, described elevating pad 5 is to water steel part No. 45, and this hardness of watering steel part is higher, makes this elevating pad 5 can bear the pressure of these other all parts of electricity liquid hammer.
Obviously, those skilled in the art can carry out various changes and distortion to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
