Technical Field

The invention relates to a counter-impact type press machine with a motor and a hydraulic cylinder for driving an upper hammer head and a lower hammer head to move respectively, which can be widely applied to the forming process of a forged piece, and is particularly suitable for the forming process of a large forged piece.

Background

With the development of society, forgings tend to be large-sized, and large striking energy and forging force are required. The existing press machine forges the one-way sliding block type hammer, and a large forging product is difficult to form, difficult to mold and inconsistent in forging density, so that the quality of a finished product forging is seriously influenced. But also can bear quantitative cold shock force, is easy to deform and break and has short service life. If the service life is prolonged, the base of the machine body needs to be enlarged, so that the manufacturing cost of the equipment is increased.

In addition, the traditional counter-blow hammer adopts compressed air or steam as power, because a compressed air or steam conveying pipeline is large, a large amount of leakage exists, the energy profit rate is very low, and meanwhile, a large amount of waste gas or waste water is discharged in the working process, so that the environment is polluted; in addition, the linkage of the upper hammer head and the lower hammer head of the traditional counter-blow hammer is realized by adopting a steel belt or a steel wire rope, the structural equipment has larger structural size, meanwhile, the service life of the steel belt or the steel wire rope is shorter, safety accidents can occur once the steel belt or the steel wire rope is broken, and in addition, the service life of the hammer head is shorter, and the use requirement cannot be met; meanwhile, a common counter-blow hammer is not provided with a stroke alarm device, so that the counter-blow hammer is often stuck due to over-expansion after being used for a long time; and the existing counter-blow hammers all adopt a manual control mode to complete work, so that the cost input is greatly increased, and the human resources are wasted.

The invention relates to a counter-impact press with a motor and a hydraulic cylinder respectively driving an upper hammer head and a lower hammer head to move, which has the working principle that: a motor and hydraulic double-power driving system is adopted to respectively control the movement of the sliding block type upper hammer and the lower hammer. On the upper part of the device, a motor drives a driving gear to rotate, the driving gear drives a flywheel type large gear to rotate through gear meshing transmission, the flywheel type large gear drives a screw to rotate, the screw is converted into linear motion of a copper nut through screw pair transmission with the copper nut, and the copper nut drives a slider type upper hammer head to move up and down; and at the lower part of the equipment, the high-pressure oil pump conveys hydraulic oil into the annular cavity, and the annular piston rod is pushed to move up and down under the action of the hydraulic oil, so that the lower hammer head is driven to move up and down. When the forging piece is formed, the forging die is located between the slider type upper hammer head and the lower hammer head, the slider type upper hammer head and the lower hammer head move towards the forging piece direction simultaneously, namely the slider type upper hammer head moves downwards, and the lower hammer head moves upwards, so that the counter-blow forging piece is formed. After the striking is finished, the hydraulic ejection cylinder acts, a piston rod of the hydraulic ejection cylinder moves upwards, the ejection rod is driven to move upwards, and the forge piece is ejected out. Then the slide block type upper hammer head, the lower hammer head and the ejector rod return to reset. Thus, a work cycle is completed.
