Abstract
The utility model discloses an alloy mandrel, which comprises a core bar and an alloy head. A raised connector is arranged at the top end of the core bar. A connecting groove is formed in the alloy head. The alloy mandrel has the advantages that the connector is matched with the connecting groove, so that the core bar can be firmly connected with the alloy head; and a welding-major connecting way is not adopted, so that the yield of a product can be greatly improved.
Description
Technical field
The utility model relates to the alloy plug.
Background technology
When magnetic industry compacting tool set, often need to use the plug with alloy, present alloy plug all is that the mode of alloy head by welding is connected to reduce production costs with the cast iron core bar, but adopt welding manner to make easily alloy part craze and transfiguration, particularly produce diameter greater than the alloy plug more than the 20mm, percent defective is high.
The utility model content
The purpose of this utility model is to provide the alloy plug, can solve effectively that alloy head is connected the high problem of percent defective on the existing above alloy plug of diameter 20mm with core bar.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the alloy plug, comprise core bar, alloy head, and the top of described core bar is provided with the connector of protrusion, and described alloy head is provided with link slot.
Preferably, described connector and link slot adopt interference fit; Utilize interference fit that core bar and alloy head are firmly linked together, be connected and fixed mode and need not to re-use other.
Optionally, described connector is provided with external screw thread, is provided with the internal thread suitable with connector in the described link slot; The another kind of mode that can firmly alloy head be connected with core bar.
Preferably, between the external cylindrical surface of described core bar and the alloy head by being welded to connect; The connector that prevents core bar withdraws from the link slot of alloy.
Compared with prior art, the utility model has the advantages that: the employing connector cooperates with link slot, core bar and alloy head can firmly be linked together, and do not adopt to be welded as main connected mode, can greatly improve the yields of product.
Description of drawings
Fig. 1 is the structural representation of the utility model alloy plug embodiment one.
The specific embodiment
Embodiment one:
Consulting Fig. 1 is the embodiment one of the utility model alloy plug, and the alloy plug comprises core bar 1, alloy head 2, and the top of described core bar 1 is provided with the connector 3 of protrusion, and described alloy head 2 is provided with link slot 4, and described connector 3 adopts interference fit with link slot 4.
After alloy head 2 and core bar 1 processed, can adopt alloy head 2 temperature are raise, make link slot 4 sizes become large, connector 3 is inserted in the link slot 4, after waiting again alloy head 2 temperature to be reduced to room temperature, link slot 4 sizes are dwindled, and link slot 4 and connector 3 interference fit firmly link together core bar 1 and alloy head 2.Present embodiment is simple in structure, need not to use welding, reduces production technology, has improved the yields of product.
Embodiment two:
The alloy plug, comprise core bar 1, alloy head 2, the top of described core bar 1 is provided with the connector 3 of protrusion, described alloy head 2 is provided with link slot 4, described connector 3 is provided with external screw thread, be provided with the internal thread suitable with connector 3 in the described link slot 4, between the external cylindrical surface of described core bar 1 and the alloy head 2 by being welded to connect.
The connector 3 of core bar 1 is screwed in the link slot 4 of alloy head 2, then adopting welding to prevent that both from relatively rotating, although present embodiment also adopts welding, but the purpose of welding only is to prevent that core bar 1 and connector 3 from relatively rotating, rather than the picture in the past technique be for both are closely connected, so the impact of the involutory golden head 2 of the welding in the present embodiment is less, equally also can greatly improve the yields of product.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (4)
