Abstract
A multi-needle impact head for ultrasonic impact gun is characterized by that more than 3 impact needle holes are made on its strip-shaped end face for mounting impact needles in it, in said impact needle hole there is a conic segment, and a fastening joint is arranged at another end of impact head. Its advantages are high efficiency increased by 100-150%, high impact force, and improving the fatigure strength of welded point by 5-10%.
Description
Technical field
The invention belongs to the welding equipment class, relate in particular to the device that welded joint fatigue strength is handled.
Background technology
Metal solder is a kind of processing technology commonly used in the process of metal working.Metal material is after welding, because the stress of toe of weld is concentrated the effect that reaches factors such as residual-tensile stress, the fatigue behaviour of welding point is far below base metal.The general normal crack initiation of its fatigue crack is in welding toe, cause fatigue crack occurring as the welding position of some large welded structures spares such as offshore platform, bridge, some taking place lose great catastrophic failure, all brings for people's aspects such as economy, work, life, personal safety and seriously influence.Therefore, the fatigue strength that improves welding point has become the difficult problem of the long-term tackling key problem of people.Studies show that: adopt the ultrasonic impact device that the toe of weld of welding point is handled, can increase substantially the fatigue behaviour of welding point.But be round owing to adopt the output of luffing bar in installing and impact head in the past, limit by geometry, can only be provided with 3 at the impact head and impact pin holes, cause shock treatment speed not high; The shock treatment operation can't be carried out in the place that soldering angle is little, thereby is difficult to promote in a few thing place, uses and operation.
Summary of the invention
The purpose of this invention is to provide a kind of multi-needle impact head for ultrasonic impact gun, to solve an above-mentioned difficult problem.
The object of the present invention is achieved like this: a kind of multi-needle impact head for ultrasonic impact gun, the present invention is that the end of impacting head is set to the strip end face.The strip end face is provided with the impact pin hole more than 3, impacts pin hole inner end portion and is provided with a conical section respectively.The other end of impacting head is provided with and is fastenedly connected body.
Because the present invention has adopted above technical scheme, its impact cephalic par can install the striker pin more than 3, thereby can significantly improve treatment effeciency in the ultrasonic impact operating process.Through facts have proved, the present invention impacts head than existing three-hand type can increase work efficiency 100～150%.And its impulsive force, impact strength and the improvement degree of welded joint fatigue strength etc. is all impacted head than three-hand type improve more than 5～10%, and all can carry out many-sided characteristics such as blasting operation in less welding corner, thereby obtain the excellent results of aspects such as fabulous work and economic benefit.
Description of drawings
Fig. 1 is the front view of a kind of multi-needle impact head for ultrasonic impact gun of the present invention;
Fig. 2 is the cutaway view of Fig. 1.
Among the figure;
1, impacts 2, strip end face 3, impacts pin hole
4, be fastenedly connected body 4-1 connecting hole
Embodiment
Below in conjunction with accompanying drawing enforcement of the present invention is explained as follows:
In Fig. 1, Fig. 2, to impact 1 an employing metal material and make, one end is set to strip end face 2.Strip end face 2 be provided with more than 3 (as 4,5,6,7,8 ...) impact pin hole 3; But its many are impacted pin hole 3 in-lines or the arrangement of other shape.Impact pin hole 3 inner ends and be provided with conical section or the chamfering that is complementary with striker pin, to guarantee that striker pin is packed into and not drop out and not interlock during shock treatment work.Impact an other end of 1 and be provided with the body 4 that is fastenedly connected that matches with impact gun and be square hole shape, the edge that square hole shape is fastenedly connected body 4 is provided with many connecting hole 4-1 that match with impact gun.Impacting an other end of 1 is fastenedly connected the screw-type that body 4 also can be set to match with impact gun and is fastenedly connected body.
For assembling, be beneficial to the needs of operation, observation and aspect such as attractive in appearance, impact a strip end face 2 of 1 and be fastenedly connected the identical shape that body 4 structure between it can be set to other shapes such as squarer or round platform.
Multi-needle impact head for ultrasonic impact gun of the present invention also is applicable to magnetostriction type ultrasonic impact device.
