Description
Technical field
The present invention relates to a kind of stamping machine, belongs to mechanical field.
Background technology
Stamping machine is exactly a punching type forcing press.In national product, Sheet Metal Forming Technology due to processing than tradition machinery for have section
About material and the energy, efficiency high are high to operator's technical requirements and can make machining institute nothing by various mould applications
The product that method reaches these advantages, thus its purposes is more and more extensive.
The design principle of stamping machine is that circular motion is converted to linear motion, and mair motor rotating shaft drives driving tooth by transmission device
Wheel, driving gear and flywheel engaged transmission, flywheel are arranged on bent axle by clutch, installing connecting rods on bent axle, interlinking lever end
If slide block, flywheel drives crank rotation, bent axle to drive drift to move along a straight line.Flywheel dimension is larger, so general by casting
Form, cast iron intensity difference itself, simultaneously because the difference of casting technique, each gear-tooth strength is also different.In normal working conditions,
During gear teeth stand under load, tooth root in the presence of alternate load, along with tooth root transition portion the abrupt change of cross-section and machining spur etc. cause
Stress concentration effect, when the gear teeth repeat stand under load after, fatigue crack will be produced at tooth root, gear teeth fatigue break is finally made.?
When the gear teeth are subject to overload suddenly, it is possible that the gear teeth snap or cut off.In addition, when after wheel odontotripsis, transverse tooth thickness is too thinning,
Break of gear tooth also can occur in normal conditions.
When punch press works, quickly, impulsive force is very big, typically now setting-up eccentricity brake wheel on bent axle for the drift downstream rate of punch press
Slowed down, while being also used for ensureing the normal of clutch, but brake wheel is easy to wear, after abrasion between eccentric wheel and brake block between
Gap increases, and reduces braking effect.
Content of the invention
According to deficiency of the prior art above, the technical problem to be solved in the present invention is:A kind of stamping machine is provided, the gear teeth are circle
Cambered surface, is engaged by arc surface between gear, and the gear teeth are contacted by cambered surface in engagement process, gear teeth each several part uniform force,
Prevent from beating tooth.
Stamping machine of the present invention, including driving gear and driven gear, driving gear is connected with machine shaft by transmission device
Connect, driven gear is fixed on bent axle, driving gear transmits power by engaging with driven gear, the gear teeth on driving gear
Working face is circular arc, arranges the groove of circular arc, groove and the inner surface and the gear teeth of groove during gear teeth meshing on driven gear
Outer surface is snuggly mated to together.
Operation principle and process:
During work, groove is snuggly mated to together with the outer surface of the gear teeth with the inner surface of groove during gear teeth meshing, driven gear with
Driving gear is engaged by circular arc plane from start to finish, relative to now cogged linear contact lay stress evenly, greatly
Big reduction broken teeth probability.
Driving gear both sides distinguish strap, between clamping plate by bolt installation cylindrical roll, Boards wall on driving gear,
Driven gear is engaged with the arc surface of cylindrical roll, and in engagement process, cylindrical roll is rotatable, change sliding friction into rolling friction, greatly
Abrasion is reduced greatly.
Reinforcing bar is embedded with along Impact direction in frame, similar to reinforced concrete structure, as frame build is larger, is usually led to
Cross pig iron casting to form, due to the impact of casting technique, the stress of frame each several part is inconsistent, the supporting part stress in punching press
Larger, frame easy fracture, now reinforcing bar can improve the intensity of frame, prevent frame rupture.
Rebar surface arranges raised, the raised frictional force that can increase between reinforcing bar and frame, prevents phase between reinforcing bar and frame
To movement.
A screw rod is passed through in frame top, on connecting rod bearing shell lid, screw rod upper and lower ends are combined with nut to screw rod lower hinge,
Top nut and frame between set row spring, set up spring between the nut of lower section and frame, when deflection of crankshaft position to
During upper rotation, up spring is pressurized, prevents connecting rod up too fast, makes clutch normal, when deflection of crankshaft position rotates down,
Descending spring is pressurized, prevents connecting rod descending too fast, damages drift and mould, while ensureing the safety of operating personnel.
The present invention is had an advantageous effect in that compared with prior art:
Stamping machine of the present invention, driven gear and driving gear are engaged by circular arc plane from start to finish, phase
For now cogged linear contact lay stress evenly, is substantially reduced in broken teeth probability, frame and is embedded with reinforcing bar, class along Impact direction
Reinforced concrete structure is similar to, reinforcing bar can improve the intensity of frame, prevents frame from rupturing, substantially prolongs the service life of punch press,
Save maintenance time and cost.

Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
As Figure 1-Figure 5, stamping machine of the present invention, including driving gear 2 and driven gear 3, driving gear 2 leads to
Cross transmission device to be connected with machine shaft, driven gear 3 is fixed on bent axle, driving gear 2 is by engaging with driven gear 3
Transmission power, the working face of the gear teeth 4 on driving gear 2 is circular arc, arranges the groove 5 of circular arc on driven gear 3,
When groove 5 is engaged with the gear teeth 4, the inner surface of groove 5 is snuggly mated to together with the outer surface of the gear teeth 4.
Operation principle and process:
During work, when groove 5 is engaged with the gear teeth 4, the inner surface of groove 5 is snuggly mated to together with the outer surface of the gear teeth 4, from
Moving gear 3 and driving gear 2 are engaged by circular arc plane from start to finish, are received relative to now cogged linear contact lay
Power evenly, substantially reduces broken teeth probability.
Strap 11 is distinguished in 2 both sides of driving gear, installs cylindrical roll 8, driven gear 3 by bolt 10 between clamping plate 11
Engage with the arc surface of cylindrical roll 8, in engagement process, cylindrical roll 8 is rotatable, and change sliding friction subtracts significantly into rolling friction
Little abrasion.
Reinforcing bar 7 is embedded with along Impact direction in frame 1, similar to 7 xoncrete structure of reinforcing bar, due to 1 build of frame larger,
Form generally by pig iron casting, as the impact of casting technique, the stress of 1 each several part of frame are inconsistent, receive in punching press
Power is larger, 1 easy fracture of frame, and now reinforcing bar 7 can improve the intensity of frame 1, prevent frame 1 from rupturing, simultaneously because reinforcing bar
Casting temperature of the fusing point higher than cast iron, will not be melted reinforcing bar or change reinforcing bar self attributes when casting.
Reinforcing bar 7 is high strength cast iron.
7 surface of reinforcing bar arranges raised 6, raised 6 and can increase the frictional force between reinforcing bar 7 and frame 1, prevents reinforcing bar 7 and machine
There is relative movement between frame 1.
A screw rod 13 is passed through in frame top, on connecting rod FE Tiler 17,13 upper and lower ends of screw rod coordinate screw rod lower hinge
There is nut 12, row spring 14 is set between the nut 12 of top and frame 1, is set up between the nut 12 of lower section and frame 1
Spring 15, when 16 bending position of bent axle is rotated up, up spring 15 is pressurized, prevents connecting rod 18 up too fast, make from
Close normally, when 16 bending position of bent axle is rotated down, descending spring 14 is pressurized, prevents connecting rod 18 descending too fast, damage punching
Head and mould, while ensure the safety of operating personnel.
Improvement to gear and frame 1 of the present invention is can be applied not only on stamping machine, every application gear and cast iron
The frame for movement of frame 1 can apply the size and number of this improvement, reinforcing bar 7 be changed according to force environment.
