Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Fig. 1 to Fig. 6 is referred to, the utility model embodiment includes：
A kind of electromagnetic type times strength hammer, including：Cylinder 1, block 11, hammer body 3, connecting rod 6, magnetic force generator 4, air storage chamber 7
With magnetic valve 8；The block 11 is fixed on the inwall of cylinder 1, and the distance of block 11 to cylinder head is block to cylinder bottom
3 times of distance；Piston 2 slidably is provided with the space below block in the cylinder, the hammer body 3 is fastened on
Piston lower surface, the lower end of hammer body 3 stretch out in cylinder bottom；The connecting rod 6 is fixed on piston upper surface, and small end stretches out in gas
At the top of cylinder, small end is fixed with iron plate 5, and the corresponding iron plate of the magnetic force generator 4 is set；The upper and lower ends of cylinder 1 difference
Provided with air inlet pipe 9 and blast pipe 10, the one end of air storage chamber 7 connects with air inlet pipe 9, and magnetic valve 8 is fixed on the air storage chamber other end.Air inlet
Pipe is provided with air gauge, and blast pipe is provided with gas bleeder valve.The bottom of cylinder is provided with cushion pad, and cylinder is played a protective role；Institute
State air storage chamber to connect with air inlet pipe, air storage chamber, air inlet pipe, blast pipe there are two.Piston is close to iron plate during stop bottom and adsorbed
On magnetic force generator, now the volume of piston upper part plus air storage chamber volume be piston lower part,
Ten times of spatial volume between hammer body, cylinder inner wall.During work, magnetic force generator is opened, iron plate is adsorbed, to piston one
Individual pulling force, opens solenoid valve is toward compressed air is poured in air storage chamber and cylinder, when the normal pressure of piston upper surface is sent out more than magnetic force
During the magnetic force of raw device, piston drops rapidly, and the compressed air in air storage chamber is plus the compression in the confined space of upper piston area point
The volume of air is ten times of volume below piston, and the enough pistons of air supply complete hammering action, cylinder lower section
Steam vent it is also very big so that piston can decline rapidly, and piston has a longer descending stroke, and piston can be made to have one
Very big acceleration, the hammer body quality being connected on piston is very big, hammer body can be made to produce very big kinetic energy, in relatively small gas
Larger hammer force is realized in cylinder, effectively reduces production cost, it is applied widely.
The utility model is applied on thimble head when forging, and first by thimble end heat, using the impact of pneumatic hammer, will be pushed up
Needle end part is processed into the round platform with thimble coaxial line in mould；The a diameter of 8mm of thimble body, round platform diameter 12.5mm, round platform
Highly it is 8mm, 15 tons of impulsive force is needed when requiring that round platform edge radius of corner is 0.5mm, when requires round platform edge
35 tons of impulsive force is needed when radius of corner is 0.1mm；The complete machine-shaping of round platform be able to not can just be gone out when impulsive force is inadequate
Sample one now as shown in Figure 3, impulsive force is close and can produce sample two as shown in Figure 4 when not reaching the numerical value of requirement, circle
Angle is excessive, it is also necessary to round platform part is processed, following process, which wastes time and energy, to be also difficult to ensure the same of round platform and thimble body
Axle degree.As long as the magnetic force of magnetic force generator is adjusted into 200kg when using the utility model, the air pressure of two air storage chambers is
5kg/cm2, hammer body quality selection 20kg, just round platform edge radius of corner can be less than 0.1mm, sample as shown in Figure 5
Three, the rectangular even acute angle in round platform edge, following process is convenient and swift, without being processed again to round platform side wall, can make
Thimble body reaches good axiality with round platform.In addition, work as the hammering for needing that a diameter of 8mm workpiece head is utilized to hammer body
It is measured when power hot-working forms a diameter of 13mm round platform, during hammer body contacts that workpiece end is molded to round platform from rigid connection,
Hammer body needs to push 4mm, is 0.15s the time required to hammer body hammers 4mm when being processed on traditional punch press, is then needed using oil pressure
Longer 0.2s, workpiece has begun to cool down during the 0.15s of hammering, does not reach thermoforming purpose, similar to cold moudling,
Cold moudling not only needs bigger hammer force, not only does not reach the purpose for processing the round platform with edge of acute angle, is also easy to
There is the danger of quick-fried mould.Process same workpiece, using the utility model in the case of hammer body hammering 4mm only need 0.015s,
It is 1/10th of prior art, molding time is short, and hammering shaping can be completed before workpiece head cools down, reaches thermoforming
Purpose.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other related technologies
Field, similarly it is included in scope of patent protection of the present utility model.
