Abstract
The utility model relates to a grip finger for a manipulator used for forging for a large-scale wind power main shaft without a riser and an ingot butt, which comprises tong arms (2), sleeve seats (4) and spherical-head cylinders (5), wherein the number of the tong arms (2), the sleeve seats (4) and the spherical-head cylinders (5) is respectively two, one end of the left and the right tong arms (2) is articulated through a hinge (1), the left and right sleeve seats (4) are respectively arranged at the other end of the left and right tong arms (2), the left and the right spherical-head cylinders (5) respectively penetrate the left and the right sleeve seats (4), the spherical-head ends of the left and the right spherical-head cylinders (5) are oppositely arranged at the inner sides of the left and the right sleeve seats (4), and the other end of the left and the right spherical-head cylinders (5) is radially inserted in a fixing pin (6). By adopting the utility model, the working procedures for forging for the large-scale wind power main shaft can be reduced, the production efficiency can be improved, the forging time can be reduced, and the forging precision and the forging quality can be improved.
Description
Technical field
The utility model relates to a kind of large-scale wind electricity main-axis and forges with manipulation machine grip finger.Be mainly used in the forging of large-scale wind electricity main-axis.Also can be used for forging productions such as other class and class, plate class.Belong to the forging tools technical field.
Background technology
When forging the large-scale wind electricity main-axis forging with steel ingot, other forged shaft is the same with forging, and traditional Forging Technology is, after the steel ingot heating, forge and always the steel ingot rising head to be forged into the pincers handle that a manipulation machine clamp can be clamped earlier, for later jumping-up, pulling, quarter platform lay the first stone.After forging is finished, again pincers handle, the crop of rising head, ingot urogenesis, cut with marking knife.This forging method has the following disadvantages:
1, the first pressing tongs handle in the conventional forging process is cut the method that clamps handle, crop again and is not only bothered but also fall behind after the forging.
2, traditional manipulation machine grip finger adopts the design of V-type clamp, jaw to open grade scope little, can not from steel ingot axially, radially omnibearingly clamp whole steel ingot, therefore need to rely on the forging pincers realizing.
3, forging process is many, adds showing tremendous enthusiasm time manyly, and forging time is long, and it is low to forge efficient, the forging low precision.Simultaneously, steel ingot is long heat time heating time, and the consumption of natural gas is many, the production cost height.
4, after the conventional method forging is finished,, make steel ingot defective such as shrinkage cavity, deviation, be mingled with again pincers handle, the crop of rising head, ingot urogenesis, cut with marking knife, rimhole etc. can not early come out, and increased the forging unnecessary loss, reduced productivity effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can reduce forging process, enhances productivity, shortens forging time, improves the large-scale wind electricity main-axis that forges precision and forging quality and do not have rising head, no ingot tail forges usefulness manipulation machine grip finger.
The purpose of this utility model is achieved in that a kind of large-scale wind electricity main-axis does not have rising head, no ingot tail and forges with manipulation machine grip finger, comprises tong arm, receiver and bulb cylinder, and described tong arm, receiver and bulb cylinder all have two, about each one.
An end of two tong arms is that closing end is hinged with hinge about described, and the other end is two receivers about openend is respectively arranged with.
Two receivers about two bulb cylinders pass respectively about described, and about be arranged in opposite directions about the bulb end of two bulb cylinders about the inboard of two receivers, about the other end of two bulb cylinders radially be plugged with steady pin.
Is provided with connecting pin in the middle of the outside of two tong arms about described, be used for the manipulation machine between be connected.
The utlity model has following advantage:
1, changes the first pressing tongs handle in the conventional forging process, cut the Forging Technology that not only bothers but also fall behind that clamps, crop after the forging again.Adopt behind the utility model before heating just under the rising head of steel ingot, the sawing of ingot tail, make steel ingot forge the wind power principal axis forging and be no rising head, the forging of no ingot tail.Realized steel ingot effective weight heats forged.The main cause that can do like this, it is the change that press is handled machine grip finger clamping range and structure, traditional V-type clamp is designed to the rotatable clamp of bulb, strengthened grade scope of opening of handling the machine grip finger, make its can to from steel ingot axially, radially omnibearingly clamp whole steel ingot, no longer need to rely on the forging pincers a clamping that realizes manipulator.This bulb cylinder turns manipulation machine grip finger, also have steel ingot, steel billet are vertically holded up next function, because the clamp head has increased a rotating mechanism of sphere cylinder, an end of its clamping steel ingot, steel billet can utilize steel ingot, steel billet deadweight to make it vertically hold up.Make things convenient for steel ingot, steel billet roll forging clamping and rotating function.
2, reduced the wind power principal axis forging process behind employing the utility model, saved the first pressing tongs handle in the conventional forging process, chopped head, cut forging process such as clamping handle, reduced and added showing tremendous enthusiasm time, shortened forging time, forged efficient, can also improve the forging precision thereby improve.Simultaneously it has also shortened steel ingot heat time heating time, has reduced the consumption of natural gas, reduces energy resource consumption more than 20%, reduces iron scale more than 20%, thereby has reduced production cost.
3, before heating, just steel ingot rising head, ingot tail saw are gone behind employing the utility model, thereby make steel ingot defective such as shrinkage cavity, deviation, be mingled with, rimhole etc. promptly early come out, can take measures timely, thereby effectively guaranteed the quality of large-scale wind electricity main-axis forging, reduce the forging unnecessary loss, improved productivity effect.So more can satisfy requirement of client.
Description of drawings
The manipulation machine that Fig. 1 relates to for the utility model is handled machine grip finger structural representation.
Fig. 2 is wind power principal axis the old and new technology contrast schematic diagram.
Among the figure: hinge 1, tong arm 2, connecting pin 3, receiver 4, bulb cylinder 5, steady pin 6.
The specific embodiment
Referring to Fig. 1, the large-scale wind electricity main-axis that the utility model relates to does not have rising head, no ingot tail forges with manipulation machine grip finger, and its structure as shown in Figure 2.Comprise tong arm 2, receiver 4 and bulb cylinder 5, described tong arm 2, receiver 4 and bulb cylinder 5 all have two, about each one, an end of two tong arms 2 is that closing end is hinged with hinge 1 about described, the other end is two receivers 4 about openend is respectively arranged with, two receivers 4 about two bulb cylinders 5 pass respectively about described, and about be arranged in opposite directions about the bulb end of two bulb cylinders 5 about the inboard of two receivers 4, about the other end of two bulb cylinders 5 radially be plugged with steady pin 6, be provided with connecting pin 3 in the middle of the outside of two tong arms 2 about described.Be used for the manipulation machine between be connected.
Using method is referring to Fig. 2: be before Forge Heating, earlier the rising head of steel ingot, the whole sawings of ingot tail are got off, then use manipulation machine grip finger that the steel ingot of no rising head, no ingot tail is clamped, carry out jumping-up, pulling, round as a ball, forging step and rammer flange operation then.
