Abstract
The present invention discloses a multi-needle impact head for ultrasonic impact gun. The end of the impact head is provided with a sliver-shaped end face provided with more than three impact needle holes, wherein the inner ends of the impact needle holes are respectively provided with a conical section, and the other end face of the impact head is provided with a fastening connector. Because the present invention adopts the technical scheme, the end of the impact head can be provided with more than three impact needles so that the treatment efficiency is obviously improved in the operation process of ultrasonic impact. According to the practice, compared with the existing three-needle type impact head, the present invention can increase the work efficiency, the impact force, the impact strength, the improving degree of the fatigue strength of welded joints, etc. are increased by 5 % to 10%, minor welded corners can be implemented with impact processing operation, etc. Thus, the present invention obtains the effects of excellent work and economic benefits, etc.
Description
Technical field
The invention belongs to the welding set class, relate in particular to the device that welded joint fatigue strength is handled.
Background technology
Metal solder is a kind of complete processing commonly used in the process of metal working.Metallic substance is after welding, because the effect of factors such as the stress concentration of toe of weld and residual-tensile stress, the fatigue property of welding joint is far below base metal.The general normal crack initiation of its fatigue cracking is in welding toe, cause fatigue cracking occurring as the weld 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, personnel safety and seriously influence.Therefore, the fatigue strength that improves welding joint 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 joint is handled, can increase substantially the fatigue property of welding joint.But owing to adopt the output terminal and the impact head of horn to be round in the device in the past, limit by geometrical shape, 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 impact head is set to the long strip shape end face.The long strip shape 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 impact head is provided with and is fastenedly connected body.
Because the present invention has adopted above technical scheme, the striker pin more than 3 can be installed in its impact head end, thereby can significantly improve processing efficiency in the ultrasonic impact operating process.Through facts have proved, the present invention can increase work efficiency 100～150% than existing three-hand type impact head.And its surging force, shock strength and all improve more than 5～10% than three-hand type impact head to the improvement degree of welded joint fatigue strength etc., 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 sectional view of Fig. 1.
Among the figure;
1, impact head 2, long strip shape end face 3, impact 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, impact head 1 adopts metallic substance to make, and one end is set to long strip shape end face 2.Long strip shape 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.The other end of impact head 1 is provided with the body 4 that is fastenedly connected that matches with impact gun and is square hole shape, and the edge that square hole shape is fastenedly connected body 4 is provided with many connecting hole 4-1 that match with impact gun.The other end of impact head 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, the long strip shape end face 2 of impact head 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.
