Description
Technical field
A kind of small-sized forging belt drop hammer, belong to forging machinery technical field.
Background technology
The forging such as hardware, mine railway spike, nail uranium, bitch, manually forge to compare and take a lot of work, and worker's physical demands is big,
Border is not protected, and cost is high；Again very high using the equipment manufacturing cost of hot forming, batch production does not have corresponding demand market again；Make
Forged with pneumatic hammer also uneconomical, cost is too high, can increase product cost；When small-sized extension spring forging hammer rotating speed is too high, easily tear open
Disconnected extension spring, it is only suitable for low speed operation.
The content of the invention
In order to solve problem above, the present invention designs a kind of small-sized forging belt drop hammer, for the processing of small shape handware, solution
Determined easily broken extension spring the problem of, tire belt is durable in use.
In order to solve the above technical problems, the present invention designs a kind of small-sized forging belt drop hammer, including:Jump bit shell, on
Square frame, sliding sleeve, guide rod, shell Zhi Xiao, jump bit sliding sleeve, jump bit, tire belt, jump bit belt ear, U-shaped adjustment spiral shell

Make belt drop hammer frame, foot control device armed lever, eccentric wheel, eccentric wheel counterweight and get rid of iron, polished or mould, flat board belt, tire belt lock
Tight screw, the round seat of matrix half, half planchet, adjusting nut.
It is characterized in that:Jump bit shell corner is provided with sliding sleeve, is guide rod among sliding sleeve, the upper end of four guide rods
Fixed with top frame, the lower end of four guide rods is separately mounted to forge in belt drop hammer frame.
Jump bit shell upper is provided with jump bit sliding sleeve, is jump bit in jump bit sliding sleeve, and during operation, jump bit is rushing
Moved up and down in hammer sliding sleeve, caused inertial impact force impacts workpiece.
Both sides, which are welded, among jump bit jump bit belt ear, middle to be connected by tire belt with U-shaped adjustment screw, when
When jump bit shell moves up and down, driven wheel periderm band, tire belt drive jump bit moves up and down, by the bullet of tire belt
Power, the upper and lower of jump bit is thrown away stroke lengthening, produce impulse inertia power, thus increase several times impulsive force, forging is obtained
The deformation compression that must be needed.
Jump bit belt ear both sides are respectively installed by tire belt.
Tire belt is process with junked tire, and the both sides of junked tire are cut off, and stays centre to contact 60- with ground
Ring-like part wide 80mm.
Install both sides tire belt when, take ring-like one section of tire belt, be through jump bit belt ear and it is U-shaped adjustment screw it
Between, tense, head end and tail end are overlapped into 100-200mm length, tire belt lock screw is used by three-ply tire belt lock in centre
Tightly.
U-shaped adjustment screw in jump bit shell end head Transverse to the round seat of matrix half that is welded, the planchet of half round seat middle pad of matrix half,
Dress adjusting nut outside half planchet, when jump bit is run up and down, half planchet moves in the round seat transfer of matrix half, can reduce U-shaped tune
Whole screw abrasion.
Adjusting nut outside half planchet can adjust the elasticity of tire belt, for controlling main shaft under certain rotating speed,
Jump bit can produce the impulsive force of maximum；If tire belt is too tight, impulsive force is small, and tire belt is easily broken；Tire belt is too
Pine, jump bit looseness is powerless, and complete machine can produce whole dynamic.
