Technical field

The utility model relates to a kind of forging hammer that forges usefulness, particularly relates to a kind of new swage that falls cover that has that forges square billet and pole material function that has simultaneously.

Technical background

At present the forging of pole material is to adopt press or forging hammer utilizes the arc anvil square billet to be processed into the forging of sub-circular.As Fig. 2 is the schematic diagram that hydraulic hammer arc anvil forges the pole material.Its technology is: the part of being made up of last arc anvil and tup that falls pumps in the rotary course that square billet does not stop, utilize the intrinsic radian of upper and lower arc anvil that square billet is become 16 faces by 8 faces, become 32 faces by 16 faces, the rest may be inferred becomes the bar of sub-circular gradually.

Though conventional device can be forged into square billet the pole material, the course of work of this device is very big to the damaged condition of equipment.Its reason mainly is eccentric the forging.Square billet is not through machined before the forging square billet, so do not have the geometric shape of rule, even have the geometric shape of rule, the geometric shape that after forging several times, does not also possess rule, therefore by on falling of forming of arc anvil and tup contact point can not be at every turn all at central point in the process that partly pumps, certainly will will cause eccentric the forging like this, eccentric as you know harmfulness of forging equipment is very big, especially the impact forging equipment.Concrete harm embodies in the following areas: 1. hammer stem is easily broken; 2. tup and slide plate dovetail serious wear; 3. liner plate is easily broken; 4. end opening envelope serious wear causes leakage of oil.

The utility model content

The purpose of this utility model is to have eccentric problem of forging in order to solve existing equipment, a kind of new swage that falls cover that has is provided, can effectively prevent eccentric the forging, and when evolution base and forging pole material, can change fast, significantly enhance productivity and security reliability.

For achieving the above object, the technical solution adopted in the utility model is: a kind of have a new swage that falls cover, comprise tup, be connected the tup lower end last flat anvil, be positioned at the following flat anvil of flat anvil below, comprise that also one is fallen cover and is positioned over the last tup and the following tup of falling in the cover, form an arc-shaped cavity that is used to hold square billet between last tup and the following tup, falling cover is movably connected in down on the flat anvil, when needs, falling cover, can to drive tup and following tup mobile together and be positioned over down the upper surface of flat anvil.

In such scheme, a described side of falling cover is movably connected in down on the flat anvil by a rotating shaft, and falling cover can rotate around the axis, and the lower end of rotating shaft is fixedly connected on down on the flat anvil.

Further in the scheme, be connected with a fixator on the described following flat anvil, the upper end of fixator is connected with a block, and block can rotate around fixator, and the free-ended top of block can be against on the outer wall that falls cover of a relative side with rotating shaft.

From above-mentioned architectural feature of the present utility model as can be seen, its advantage is: fall cover and played good effect of contraction, last tup and following tup are formed a complete arc-shaped cavity, in the process of forging, well solved the eccentric forging problem big equipment damage.In addition, fall and be enclosed within the extent of damage that has not only reduced in the forging hammer production bar process equipment, and more convenient tissue production, its reason is that the arc anvil that adopts forges in the past needs earlier square billet to be melted down heating after square billet is held successfully, after being dismantled, upper and lower flat anvil changes the arc anvil, like this time spent very long, want at the soonest both to waste energy like this more than half an hour, and strengthen direct labor's labour intensity, frequently change hammering block and also strengthened infringement equipment.Utilization rotates to down the flat anvil upper surface as long as will fall cover after falling and holding square billet successfully when cover forges the pole material, just can begin after blocking with block then to forge circle, the time spent has only several seconds, thereby has realized forging hammer evolution base in the past, and another forges the forging of uniting of circle.Both energy savings can reduce labour intensity again, more can enhance productivity.
