Abstract

The utility model relates to a wire harness welding machine, which comprises upper and lower welding heads, wherein the upper and lower welding heads are respectively provided with ladder-shaped steps which are matched with each other; upper and lower side walls of the two steps are in surface contact under a mold closing state; the vertical distance between the step of the upper welding head and a bottom wall, and between the step of the lower welding head and a top wall, is no less than the diameter of the end part of a wire harness; when the mold is closed, the steps of the upper and lower welding heads form the top wall and the bottom wall of a welding cavity respectively, and the lower side wall of the step of the upper welding head and the upper side wall of the step of the lower welding head form two side walls of the welding cavity respectively. The wire harness welding machine can be shaped through one-time sintering, enables the welding efficiency to be improved greatly, and can save energy.

Description

The wire harness heat sealing machine

Technical field

The utility model relates to a kind of wire harness heat sealing machine that multiple conducting wires is welded together by sintering.

Background technology

Usually, for the connecting line that forms external connection electrical apparatus than thin wire by many, in order to improve its overcurrent performance, two ends need to be carried out sintering with heat sealing machine and be melted, and make thin wire be fused into integral body, could be with its welding on the input of electrical equipment, output chip.That this heat sealing machine generally arranges in the middle of lower welded joint roof is downward, be used for placing the welding die cavity of wire harness end, and upper and lower welded joint matched moulds and heating are compacted into wire harness and sinter into block spade tip.This heat sealing machine just can be completed by three sintering of needs.Because wire harness end multiple conducting wires is deposited in the welding die cavity, it is more that its top exceeds the welding die cavity, during welding for the first time the part wire can landing to the roof of lower welded joint welding die cavity both sides, form projection in spade tip both sides, need that turnback is turned in the end of welding for the first time in the welding die cavity and carry out welding shaping for the second time, eliminate the both sides bossing, and then it is turned over turnback carry out the sintering typing.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and a kind of wire harness heat sealing machine is provided, and only needs once sintered can the typing, has advantages of that welding efficient is high.

The utility model is achieved in that and comprises upper and lower welded joint; Be respectively equipped with the stairstepping step that cooperatively interacts on upper and lower welded joint, the width of step equates with spade tip cross-sectional length after fusion molding; The upper side wall of two steps, lower wall are respectively the face contact under the matched moulds state; Vertical range between upper welded joint step and diapire and lower welded joint step and roof is not less than the diameter of wire harness end; When upper and lower welded joint matched moulds, the step of upper and lower welded joint consists of respectively roof and the diapire of welding die cavity, and the upper side wall of the lower wall of upper welded joint step and lower welded joint step consists of respectively two sidewalls of welding die cavity.

During sintering, first the wire harness end is placed on lower welded joint step by the gap between lower welded joint roof and upper welded joint step.During matched moulds, upper welded joint is descending, and upper side wall, the lower wall of two steps contact respectively, the wire harness end total is enclosed in the cavity that two steps and sidewall thereof surround, again to the matched moulds state, when making the wire harness end capacity compression wire can landing to outside, once sintered can the typing.

Preferred version of the utility model is: upper welded joint diapire extends to below the step place or step of lower welded joint; Gap between lower welded joint roof and upper welded joint step is enough to make the wire harness end to be passed through.The lower wall of upper welded joint step and lower welded joint step and upper side wall thereof consist of the welding die cavity, the wire harness end is all inserted in the welding die cavity by the gap between lower welded joint roof and upper welded joint step, the part wire can not occur and be scattered to the step outside of lower welded joint.

The utility model forms dynamic welding die cavity by sidewall of welding die cavity is arranged on upper welded joint.During matched moulds, the wire harness end total is enclosed in the cavity that two steps and sidewall thereof surround, then to the matched moulds state, when making the wire harness pressurized wire can landing to outside, once sintered can the typing makes the welding efficiency width improve, and can conserve energy.

Embodiment

As shown in Figure 1 to Figure 3, upper and lower

welded joint

1,2 is fixed on heat sealing machine by installing

handle

15,25 respectively.Be respectively equipped with the

stairstepping step

13,23 that cooperatively interacts on upper and lower

welded joint

1,2,

step

13,23 width equate with spade tip 41 cross-sectional length after fusion molding; Two

steps

13,23

upper side wall

14,22, and

lower wall

12,24 is respectively the face contact under the matched moulds state; Vertical range between upper welded joint step 13 and diapire 14 and lower welded joint step 23 and roof 21 is not less than the diameter of wire harness end 4; When upper and lower

welded joint

1,2 matched moulds, upper and lower

welded joint

1,2

step

13,23 consist of respectively roof and the diapire of welding die cavity, and the upper side wall 22 of 12 times welded joint steps 2 of lower wall of upper welded joint step 1 consists of respectively two sidewalls of welding die cavity.

Its operation principle as shown in Figure 2 and Figure 3.During sintering, first wire harness end 4 is placed on lower welded joint step 23.During matched moulds, upper welded joint 1 is descending, the upper side wall 14 of two steps, 22 and

lower wall

12,24 contact respectively, with wire harness end 4 be completely enclosed within two

steps

13,23 and the cavity that surrounds of

sidewall
