Abstract
The invention discloses a special novel connecting needle for fins. The special novel connecting needle for the fins is composed of a needle root, a fixing sleeve and a needle body. The top end of the needle root is provided with an external threaded section with a specific length. The fixing sleeve is a circular ring with an internal thread. The needle body can be divided into three parts including the tip part with the specific length, the internal threaded bottom section with the specific length and the middle part with the smooth outer surface. The needle root, the fixing sleeve and the needle body are made of alloy steel subjected to quenching and tempering. The length of the connecting needle can be determined according to the actual use conditions. The connecting needle is high in strength, good in wear resistance and suitable for ordered arrangement and connection of the fins during continuous punching production.
Description
Technical field
The present invention relates to novel splicing pin, specifically belong to a kind of fin special utility splicing pin.
Background technology
Evaporator fin needs a large amount of fins in manufacturing process, and the manufacturer of state's inner fin adopts the continuous punching of middling speed punch press to produce mostly.But, need when actual production to use continuous fin material-receiving device that the fin of punching is carried out ordered arrangement splicing.Need splicing pin to be installed on material-receiving device for this reason.At present, when inner fin manufacturer of state uses splicing pin to produce, often run into following problem: 1, splicing pin size is not mated with position, the hole size of fin, cannot splicing in order.2, splicing pin intensity is not enough, very easily ruptures.3, do not stop shake during the actual use of splicing pin, cannot splicing in order.For this reason, new design must be adopted to develop design to splicing pin, just can solve the problem.
Summary of the invention
The invention provides a kind of fin special utility splicing pin, splicing pin does not stop shake, intensity is not enough and the shortcoming of easily fracture to adopt new design to solve, strict controlling dimension and tolerance when actual processing and manufacturing simultaneously, ensure that splicing pin mates with position, fin hole, eliminating cannot the problem of splicing in order.The present invention is reasonable in design, safe and reliable in actual production use procedure, splicing pin long service life.
The technical solution adopted in the present invention is as follows:
A kind of fin special utility splicing pin, is made up of the crown, fixed cover and needle body.Wherein there is length-specific external thread section on the top of the crown, and fixed cover is annular band internal thread, and needle body can be divided into three parts: the mid portion of the tip portion of length-specific, the band female thread portion of bottom length-specific and smooth outer surface.The crown, fixed cover and needle body adopt the materials processing of steel alloy after modifier treatment to be made.
The external thread section length of the described crown is 14mm ± 2mm, and the length of the crown is not less than 1/3rd of splicing pin overall length, is not more than 1/2nd of splicing pin overall length.Annular fixed cover is by being screwed on the junction of the crown and needle body.The minimum diameter of the tip portion of needle body is 1.5mm ± 0.1mm, and the transition region of the mid portion of tip portion and smooth outer surface is not less than 40mm.
The described crown, fixed cover and needle body adopt steel alloy to manufacture through modifier treatment aft-loaded airfoil.Steel alloy tensile strength after modifier treatment is not less than 340KN.The outer surface fineness of the crown and needle body reaches national grade ii standard.
Compared with the prior art, beneficial effect of the present invention is as follows:
Splicing pin is divided into three large parts independently to process by the present invention, and then the patten's design manufacture of splicing.Solve splicing pin size not mate with position, the hole size of fin, cannot splicing in order; Splicing pin intensity is not enough, very easily ruptures; Shake is not stopped during the actual use of splicing pin, cannot splicing three problem greatly in order.

Detailed description of the invention
See accompanying drawing, a kind of fin special utility splicing pin, is made up of the crown 1, fixed cover 2 and needle body 3.Wherein there is length-specific external thread section 4 on the top of the crown 1, fixed cover is annular band internal thread 5, and needle body 3 can be divided into three parts: the tip portion (as enlarged drawing) of length-specific, the band female thread portion 6 of bottom length-specific and the mid portion of smooth outer surface.The crown 1, fixed cover 2 and needle body 3 adopt the materials processing of steel alloy after modifier treatment to be made.External thread section 4 length of the described crown 1 is 14mm ± 2mm, and the length of the crown 1 is not less than 1/3rd of splicing pin overall length, is not more than 1/2nd of splicing pin overall length.Annular fixed cover 2 is fixed on the junction of the crown and needle body by screw thread 5.The minimum diameter of the tip portion (as enlarged drawing) of needle body 3 is 1.5mm ± 0.1mm, and tip portion (as enlarged drawing) adopts steel alloy through the manufacture of modifier treatment aft-loaded airfoil with the transition region crown 1, fixed cover 2 and the needle body 3 be not less than as described in 40mm. of the mid portion of smooth outer surface.Steel alloy tensile strength after modifier treatment is not less than 340KN.The outer surface fineness of the crown 1 and needle body 2 reaches national grade ii standard.
