The utility model comprises a guiding mechanism which is constituted by two guiding rollers which are installed on a casing in parallel through a roller shaft, and a shaving mechanism which is arranged between the upper cover plate of the casing and the lower cover plate of the casing. The shaving mechanism comprises a clutch cam, and the upper end of a cam shaft is connected with a shaft, a milling cam is arranged on the two sides of the clutch cam, one end of the swinging cam is connected with the upper and the lower plates through a pivot shaft, a regulation spring is arranged on the outside of the front portion of the swinging arm, and a cutting with shaving edges is installed on the front end of the regulation spring. The utility model has accurate guiding and small friction resistance, is free to damage the surface of a strip, can automatically scrap the shearing surface of the copper strip, and eliminates the shortcomings existing in the prior art. And the utility model has the advantage of guaranteeing the surface quality and welding quality of the surface of a pipe crimping and the like, which is the preferred guiding shaving device for the coating pipe-welding machine.

Description

Copper tape guide edging device

Technical field

The utility model relates to a kind of wrapping pipe welder, and particularly a kind of copper tape guide edging device is a front end band material guider first-selected on the wrapping pipe welder.

Background technology

At present domestic all produce the producer of copper-clad aluminum conductors, the general wrapping pipe welder of Shi Yonging, the band material guider of its front end all is the limit-type structure of guide groove.Because its structural design is unreasonable, cause carrying out the transition in the process of horizontal guide groove by ascending groove with material aborning, especially when band is expected through the guide groove transition point, because the pulling force of coating machine front end, the resistance of guide groove back in addition, often cause and be with material to produce sharply friction, the surface damage of being with material, the phenomenon of crossing thermal oxide are happened occasionally, have a strong impact on the surface quality and the electric conductivity of pipe crimping at the guide groove transition point.Also cause simultaneously unnecessary power consumption.Existing for these reasons band material guider has further improved necessity.

The utility model content

The problem that the utility model exists at prior art, provide a kind of simple and reasonable, band material guiding accuracy height, frictional resistance be little, do not damage band material surface, and scraping band material shear surface is guaranteed the surface quality and the welding quality of pipe crimping automatically, eliminates the defective of prior art; The copper tape guide edging device of simultaneously easy and simple to handle, stable performance.

The purpose of this utility model realizes by the following technical solutions: comprise that one is loaded on the guiding mechanism that two guide rollers on the casing constitute side by side by roller shaft respectively and is located at casing and scrapes limit mechanism between the cover plate up and down; The described limit mechanism of scraping comprises clutch cam, and the upper end of camshaft links to each other with handle, and the clutch cam both sides are located in swing arm, and an end of swing arm links to each other with cover plate up and down by hinge, and the outside of swing arm front portion is provided with regulating spring, and front end is equipped with the cutter that can scrape the limit.

The both sides of described guide roller are provided with the convex edge, take turns wide with copper strips is wide is complementary.

The spigot surface of described guide roller output and both sides scrape the limit cutter on same horizontal line.

The medial surface of described swing arm contacts with the working face of cam constantly, and contacts with the copper strips two sides when the limit cutter of scraping of cam swing arm front end during at low level, when cam during in a high position, scrapes the disengagement of limit cutter and copper strips both sides.

Described guide roller is loaded on the roller shaft by rolling bearing.

The utility model compared with prior art because two guide rollers are loaded on the roller shaft by rolling bearing, its spigot surface with scrape the limit cutter and be on the same horizontal line; Be provided with edging device between the cover plate up and down again, one end of swing arm is hinged, front part sides is provided with regulating spring, front end is provided with scrapes the limit cutter, clutch cam is located between two swing arms, its working face is all the time with a series of technical measures such as the inboard of swing arm contact and tie evidence and guiding is arranged accurately, the little band material surface of not damaging of frictional resistance.And the automatic scraping band material shear surface of energy, eliminate the shortcoming that prior art exists, guarantee the surface quality of pipe crimping, satisfy the welded tube demand of technical standard, improve welding quality and utilization efficiency of energy.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is the sectional structure schematic diagram of Fig. 1.

Fig. 3 is the B-B sectional structure schematic diagram of Fig. 2.

Fig. 4 is the A-A sectional structure schematic diagram of Fig. 2.

Among the figure: 1 camshaft; 2 handles; 4 cutters; 5 swing arms; 6 spring bases; 7 supports; 8 soket head cap screws; 9 pads; 10 springs; 11 hinges; 14 soket head cap screws; 15 clutch cams; 16 lower covers; 17 upper cover plates; 18 guide rollers; 20 roller shafts; 21 casings; 22 bearings; 23 copper strips.

The specific embodiment

Content of the present utility model further is illustrated in conjunction with the accompanying drawings by embodiment.Be installed with two guide rollers 18 side by side by roller shaft 20 in the cavity of the casing 21 shown in Fig. 1-4.Set up defences against ending and be with material 23 convex edges that wander off in the two ends of guide roller 18, its width is complementary with the band material is wide, and inside is loaded on the roller shaft 20, as shown in Figure 4 by bearing 22.Be provided with between the cover plate up and down 17,16 of casing 21 and scrape limit mechanism, comprise that an end is hinged on swing arm 5 on the

cover plate

17,16 up and down by hinge 11, the anterior outside is provided with regulating spring 10 front ends and is provided with and scrapes limit cutter 4, clutch cam 15 places between two swing arms 5, link to each other with handle 2 by camshaft 1, the working face of clutch cam 15 contacts as shown in Figure 3 with the medial surface of swing arm 5 all the time.Described regulating spring 10 comprise soket head cap screw 8 pass support 7 withstand the pad 9 springs 10 be loaded on spring base 6 in the pad 9 between.The spigot surface of described guide roller 18 outputs and both sides scrape limit cutter 4 at grade.Described up and down cover plate the 17, the 16th will separate each other and link to each other with casing by soket head cap screw 14 assemblies.

When the utility model uses, when the band material is introduced, turn handle 2 makes clutch cam 15 be in a high position, and then two swing arms 5 separate laterally, scraping limit cutter 4 leaves with the two sides of copper strips 23, when coating machine traction during through the operation of this mechanism, handle 2 forwards clutch cam 15 to low level, under the effect of regulating spring 10, scrape limit cutter 4 and contact also scraping with the two sides of copper strips 23, its cutting force size is regulated by regulating spring 10.The shear surface light of copper strips 23, smooth guarantees to weld required quality requirement after the process scraping.Therefore eliminated the shortcoming that original guide type guider exists fully.
