Description

Drop-forging hammer for making toothed wheels

(1) technical field

The utility model relates to a kind of forging machinery, specifically a kind of die hammer.

(2) background technology

Die hammer is the important machinery that forges processing.Present employed die hammer mainly contains steam drop hammer and electric liquid die hammer etc.Steam drop hammer needs huge high steam feed system, and its control ratio is difficult, and the noise that is produced is bigger.The electricity liquid hammer needs complicated hydraulic system, manufacturing cost height.No matter be steam drop hammer or electric liquid die hammer, its structure is more complicated all, and floor space is big, and energy consumption is high and can produce strong noise pollution.

(3) summary of the invention

The purpose of this utility model is to provide a kind of compact conformation, energy consumption low, drop-forging hammer for making toothed wheels that can light noise pollution.

The purpose of this utility model is achieved in that it comprises anvil block, be installed in the base on the anvil block, be installed in the body on the base, be installed in the tup on the body, hammer stem that links to each other with tup and the driving mechanism that is installed on the hammer stem, described driving mechanism comprises the casing that is installed in body upper, be provided with bearing in the casing, support, motor, reduction box, clutch, gear and tooth bar, tooth bar links to each other with hammer stem, bearing is installed in the lower box support and is hinged on the bearing, motor and reduction box are rack-mount, and gear is installed on the output shaft of reduction box, and clutch is installed in a side of casing and links to each other with support.

The utility model can also comprise following architectural feature:

1, is provided with the air-cylinder type accelerator at the top of casing.

2, be provided with dust-proof cushion between the connecting plate on hammer stem and the body.

3, body is provided with the tup guide rail.

4, body is provided with tup lifting position sensor.

5, body is provided with the hammer lock.

Operation principle of the present utility model is: by the electrical apparatus control system actuating motor, rotate through the reduction box driven gear, the gear driven tooth bar holds up tup rapidly.When tup promotes under the effect of gear, tooth bar, if be provided with the air-cylinder type accelerator at the top of casing, air can be gradually reduced and form the air cushion storage power, meanwhile under the interlock control of control system, control motor starting, come the quick clutch of control gear by control system, this moment, tup lost picking-up power upwards, and the whereabouts forms forging and hits rapidly.If be provided with the air-cylinder type accelerator at the top of casing, then air cushion expands rapidly, makes tup quicken to move downward.

The utility model is power source with the motor, gear, tooth bar are the transmission device, power source, transmission device are arranged in the casing of body upper, its structure is very compact, do not need to be provided with huge steam raising plant or complicated hydraulic system, so its compact conformation, manufacturing cost reduces, and can reduce noise pollution effectively.

Device of the present utility model has characteristics such as blow energy is big, and transmission performance is good, be suitable for processing high strength, inductile and complex-shaped, required precision is high, do not have the forging of pattern draft.Use few cutting, no Cutting Process, metal being full of property in impression is good, can forge the alloy of difficult distortion.Can cancel huge hammering block, save metal greatly.The vexed mould time has only several milliseconds, thereby the die life raising, can forge some complicated parts such as gear blank.

Directly connect between each actuated element of the present utility model, whole dynamical system is compact, and energy loss is less, and efficient is higher, and it has bigger stability, is convenient to maintenance, and handling ease, cost are low.Anvil block vibrations are less when forging, thereby public hazards are less.Simple in structure in a word, do not need to carry out complexity, firm installation basis, directly save mounting cost, relatively be suitable for middle-size and small-size manufacturing enterprise.
