Abstract
Three-hammerhead radial forging machine belongs to forging machinery.It is center disposed at equal distance radially to forge center line that three identical unit of structure forge case; The double-slider sine mechanism that each unit forges in the case drives tup strike forging; Connector forges casees with three unit and couples together in twos, and drives the unit and forge synchronously convergence or away from forging center line of case constant speed.Three-hammerhead radial forging machine of the present invention is simple for structure rationally, and the main parts size highly versatile is easy to maintenance, in light weight, compares much lower times of price with the product of Austrian GFM company.
Description
The invention belongs to radial forging, exactly belong to many hammerhead radial forging machines.
Common many hammerhead radial forging machines refer to the forging machine formed with upper ram by two comprise three tups and four tups etc.Early stage three-hammerhead radial forging machine owing to exist many shortcomings to be eliminated, replaces ripe forging machine-four hammerhead radial forging machine of a kind of technology.Its typical structure is the product of Austrian GFM company.As accompanying drawing 1, shown in Figure 2.The strike mechanism that quadruplet is made up of eccentric shaft (44), master slider (42), cross slider (48) is installed in the square solid forging case (40) with diagonal positions in pairs; Rotatablely moving of eccentric shaft (44) is converted to the straight reciprocating motion of master slider (42) by the double-slider sine mechanism, drive tup (41) bar is forged.Eccentric shaft (44) is contained in the eccentric bushing (45), worm gear (47) by leading screw (46) thus drive the position that the eccentric bushing rotation has changed eccentric shaft (44), therefore, can obtain the forging cross section of different size.There is a whole main transmission gearbox corresponding to the place of each eccentric shaft a dish type gear wheel to be arranged all within it at the rear of forging case, drive eccentric shaft (44) rotation by shaft coupling and flywheel, and four dish type gear wheels mesh with idler gear, keep the synchronous rotation of four eccentric shafts.
The shortcoming of this structure is: casing is forged in whole casting, and is bulky, heavy; Machining element is many, the required precision height, and the process-cycle is long; The inconvenience maintenance; For these reasons, the radial forging machine of GFM company becomes a kind of equipment the most expensive in the machine tool product in the world.Concerning many factories, radial forging becomes the equipment that is unable to reach, and has greatly limited this equipment and has brought into play technical economic benefit aborning.
To overcome above-mentioned shortcoming, the present invention aims to provide a kind of following three-hammerhead radial forging machine: combined frame, component structural rule, highly versatile, easily processing, assembling maintenance; Depth-feed mechanism is simple, and is easy to adjust; Improve the double-slider sine mechanism, make it to be convenient to make, running steadily; Main transmission is reliable, and transmission system is simple, and rigidity guarantees that synchronously three tups hit the uniformity of action; Cost reduces significantly.
Solution of the present invention is as follows:
Three separate unit forge case, and equidistant radially to be evenly arranged in to forge center line be on the circumference at center, connector forges case with three unit and connects together in twos, constitute the triangle rack of sealing, it is opposite that connector is that two ends have rotation direction, the thread that pitch is identical, pass the screwed hole that the unit forges the case both sides, the part that the unit forges the case upper screwed hole is appeared at one group of thread two ends wherein, being equipped with can be along thread bevel gear in axial sliding, other two groups of its flared end of pull bar also are equipped with bevel gear in axial sliding, and respectively with the engagement of corresponding bevel gear;
The unit forges a case shoring between any two, the thrust of shoring the unit is forged have between the case mutually away from trend; The triangle sealing frame places on the base, two unit that are arranged in the below forge put between case and the base one with the triangular guide at 30 ° of angles of horizontal plane folder; The unit forges case and is made of casing, eccentric shaft, master slider, cross slider, and wherein cross slider divides two former both sides that embed master slider, and eccentric shaft is equipped with flywheel and stabilizer respectively; Each unit is equipped with a gear bag, its axis (S after forging case
1) by shaft coupling transmission flywheel and eccentric shaft, axle (S
1) on bevel gear by another Bevel Gear Transmission axle (S
3), two axle (S are arranged in the gear bag of top
3) become 60 ° of distributions, and respectively with lower-left and bottom right gear bag in single axle (S
3) connect with sliding key sleeve.
Connector is an arm-tie, wherein lower pulling plate connects two unit forging casees that are arranged in the below, and is in horizontal level, and layback plate one end is fixed with the unit forging case of bearing pin and top, the other end has elongated slot, and this groove is corresponding with the elongated slot that forge on the case side former below two; Insert the wedge mechanism that is made up of voussoir, spline, leading screw in the overlapping elongated slot, leading screw drives the motion of voussoir do perpendicular to the arm-tie direction; Layback plate lower end is a horn structure, and this wedge angle wedging unit forges between the tail piece of former and lower pulling plate under case.
The screw pull bar has 6, and per 2 one group, pass the screwed hole that the unit forges the case both sides, 3 unit are forged case couple together in twos, constitute the triangle sealing frame.
Be contained on the flywheel at eccentric shaft two ends and the stabilizer balancing weight is all arranged.
Three-hammerhead radial forging machine of the present invention has following advantage:
Forge the case combined frame with the unit and replace the solid forging case, greatly reduce the manufacture difficulty of forging machine, forging casing is the most unmanageable part of radial forging, its manufacturing expense accounts for 40% of complete machine cost, and machining element is many, requires with large-scale precision boring and milling machine for sleeping in, process-cycle is long, three tup forging machines of the present invention, with the combining structure that the unit forges case and connector, it is very easy that manufacturing procedure becomes.
With the whole transmission case in the unit gear bag replacement known configurations, manufacture difficulty further reduces significantly.
Finish radial feed with the motion drive unit forging case of connector itself and move, drive one of eccentric bushing rotation in the alternative known configurations and overlap complex mechanism greatly, also can guarantee feed accuracy.
Known four hammerhead radial forging machines maintenance is very inconvenient, and 90 ° of forging case upsets that some tons are heavy will have a cover switching mechanism, and structural repair of the present invention will make things convenient for manyly, does not need special-purpose switching mechanism.
In a word, three-hammerhead radial forging machine of the present invention is because structural superiority, make complete machine heavily alleviate manyfold, structure is more succinct, and main parts size such as unit forge highly versatiles such as case and gear bag, easy to maintenance, radial forging of the present invention, its cost is compared with known four hammerhead radial forging machines, has reduced manyfold, bring into play economic benefit better for this sophisticated equipment in society and brought bright prospect, its price also will be occupied very big advantage in international competition.
