The lead frame mould
One, technical field:
The utility model relates to the lead frame in a kind of sheet metal processing, particularly discloses a kind of lead frame mould, in order to ensure by the precision of weldering framework and to reduce labour intensity and enhance productivity.
Two, background technology:
A lot of frameworks adopt Welding Structure in sheet metal processing.But in the process of welding, usually processed part distortion can take place, this is because the factors such as moving or stir of anchor point not high, the processed parts of flatness unreasonable, die face in welding process of weld mold causes.
Three, summary of the invention:
The purpose of this utility model is to overcome the shortcoming that usually can deform in the prior art middle frame structure welding process, discloses a kind of lead frame mould.
The utility model is achieved in that the size at required lead frame parts in the actual production processing, determines the length and width size of lead frame mould.The rotating shaft that entire working surface is rotated is flexibly all arranged on the left and right side support of lead frame mould.The operating handle that rotates the weld mold working face is arranged on the support of right side and can make welding job face be fixed on the location-plate of 0 °, 90 ° and 180 °.In whole welding process, just do not need like this to move the parts that need welding, avoided the error that causes thus.Simultaneously, also can reduce labour intensity, only need an operative employee just can finish in the whole welding process.
Two length fixed locating studs and four adjustable length alignment pins are arranged in the both sides of framework, alignment pin assigns in the locating hole of the framework left and right sides, the alignment pin of the same axis in both sides must keep concentricity, the location shoulder is arranged on the alignment pin, its degree of depth cooperates with locating hole on the soldered parts, simultaneously, and according to the size of lead frame, increase the locating clip of vertical direction, and be welded with fixing soldered parts in the both sides of locating clip and guarantee the guide locating device provided of soldered parts flatness.
And arranged on left and right sides at framework has locating hole at 45 mutually, fixes horizontal stroke, the right cylinder that needs lead frame by dog screw, and assurance needs the perpendicularity between the lead frame column.
Distance between alignment pin, the locating clip and quantity, it is fixed to come according to the size of need lead frame, and such mould just can satisfy the welding of different size framework.
The beneficial effects of the utility model are: with this weld mold processing framework, only need an electric welder to get final product, do not need to copy mechanically worker or other auxiliary workers.The phenomenon of processed part distortion can not take place in welding process in addition.Flatness, the perpendicularity of welding afterframe are preceding consistent with welding.

Five, the specific embodiment:
With reference to the accompanying drawings 1,2, on the left side brackets 9 of lead frame mould and right side support 3, be respectively equipped with the turning cylinder 11 that whole welding job face is rotated flexibly.
With reference to the accompanying drawings 1,2,3, the operating handle 1 that rotates the weld mold working face is arranged and can make welding job face be positioned at the circular weld working face location-plate 2 of 0 °, 90 ° and 180 ° at right side support 3.
With reference to the accompanying drawings 2, two length fixed locating studs 8 and four adjustable length alignment pins 4 are arranged in the framework both sides, simultaneously, according to the lead frame size, increase the locating clip 6 of vertical direction, and be welded with fixing soldered parts 7 in the both sides of locating clip and guarantee guide locating device provided 5 of soldered parts 7 flatness.And arranged on left and right sides at framework has locating hole 10 at 45 mutually, and adjustable length alignment pin 4 and length fixed locating stud 8 assign in the locating hole 10.
Distance between alignment pin, the locating clip and quantity, the size of lead frame is decided as required, and such mould just can satisfy the welding of various different size frameworks.
