Description
Technical Field
The invention relates to an electric and hydraulic driven upper and lower hammer head opposite-impact press which can be widely applied to forging forming processes, in particular to large forging forming processes.
Background
With the development of society, forgings tend to be large in size, requiring large striking energy and forging force. The existing press is used for forging a one-way sliding block type hammer head, so that large forging products are difficult to form, die assembly is difficult, forging densities are inconsistent, and quality of finished forging products is seriously affected. And only can bear quantitative cold impact force, is easy to deform and break, and has short service life. If the service life is to be prolonged, the base of the machine body must be enlarged, thus increasing the manufacturing cost of the equipment.
In addition, the traditional counter-hammer adopts compressed air or steam as power, and has low energy profit margin due to large leakage of the compressed air or steam conveying pipeline, and simultaneously has large discharge of waste gas or waste water in the working process, thereby causing environmental pollution; in addition, the upper hammer head and the lower hammer head of the traditional counter-hammer are linked by adopting a steel belt or a steel wire rope, the structural size of the structural equipment is larger, 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 when the counter-hammer is used, and the use requirement cannot be met; meanwhile, a general counter hammer is not provided with a travel alarm device, so that the situation that the counter hammer is blocked due to excessive expansion and contraction often occurs after the counter hammer is used for a long time; moreover, the existing counter-hammering hammer is operated in a manual control mode, so that the cost investment is greatly increased, and the manpower resource is wasted.

The invention relates to an electric and hydraulic respectively driven upper and lower hammer head opposite-impact press, which has the working principle that: and a motor and a hydraulic double-power driving system are adopted to respectively control the movement of the upper hammer head and the lower hammer head of the sliding block type. At 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 engagement 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 sliding block type upper hammer to move up and down; and the high-pressure oil pump is used for conveying hydraulic oil into the annular cavity at the lower part of the device and pushing the annular piston rod 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 is formed, the forging die is positioned between the upper sliding block type hammer head and the lower sliding block type hammer head, and the upper sliding block type hammer head and the lower sliding block type hammer head move towards the direction of the forging simultaneously, namely the upper sliding block type hammer head moves downwards, and the lower sliding block type hammer head moves upwards, so that the opposite forging is formed. After the striking is finished, the hydraulic ejection cylinder acts, a piston rod of the hydraulic ejection cylinder moves upwards to drive the ejection rod to move upwards, and the forging is ejected out. And then the sliding block type upper hammer head, the lower hammer head and the material pushing rod return to reset. Thus, one working cycle is completed.
The upper hammer head and the lower hammer head opposite-impact type press driven by electric and hydraulic respectively are driven by hydraulic, so that the transmission efficiency is high, and the impact energy can be automatically controlled. Moreover, the hydraulic drive can accelerate the lower hammer head in a short time and accumulate huge kinetic energy, so that the continuous forging is also facilitated.
According to the electric and hydraulic driven upper and lower hammer head opposite-impact press, forging force acts on the opposite-impact surface, and the buffer action of hydraulic oil in the hydraulic cylinder during impact is transferred to the hydraulic cylinder to buffer the forging force, so that impact on the ground during working is reduced, influence on other peripheral equipment is reduced, and the foundation cost is low. The bearing capacity of the machine body base is improved, so that the safety of the machine body base is ensured. Therefore, compared with the prior art, the large base of the machine body is not needed, the base of the machine body is small, the cost is low, and the service life is long.
The upper and lower hammer head opposite-impact type press driven by electric and hydraulic respectively adopts an upper guide rail, a lower guide rail, a guide sleeve and a machine body base center Kong Duochong guide structure, so that the forming precision of a forging piece is ensured.
The electric and hydraulic driven upper and lower hammer head opposite-impact type press machine provided by the invention is used for forging the forging piece by adopting the double hammer heads, so that the simultaneous compression forming in the upper and lower directions is realized, the stress of the forging piece is symmetrical, the forging precision is high, the crystal grains are thinned, the compactness of the forging piece is high, the metal structure is uniform, the mechanical property is good, the forging piece is not easy to generate internal cracks, and the forming quality of the forging piece is good.
