Abstract
The utility model relates to the field of the manufacture of power transformer, and discloses a processing mould for seal of transformer box edge, comprising an upper mould body and a lower mould body, wherein, a rectangular groove is formed between the upper mould body and the lower mould body, and the width of the rectangular groove equals the width of the seal; and the upper mould body is provided with saw kerfs which have an included angle with the cross-section of the rectangular groove and pass through the bottom of the groove.
Description
Technical field
The utility model relates to power transformer and makes field, particularly a kind of processing mold that is used for transformer tank along sealing strip.
Background technology
In power transformer was made, its case adopted sealing strip along sealing.For the joint bonding that makes sealing strip is firm, way is that length direction and joint cross section with sealing strip forms an angle usually, and expansion joint area of section has promptly enlarged bond area.In the reality of work, generally estimate earlier the length of sealing strip on sealing strip, to cut out 60 ° opposite joint cross section of both direction with electrician's knife then, use the bonding oven dry of glue again.
But this method has following shortcoming: (1) the method has certain requirement to operator's technology, if the bad sealing strip that might cause in joint cross section is scrapped; (2) operator is at cutting joint cross section possibility cut wound hand; (3) chamfered surface that cuts out with electrician's knife is too smooth, and this can cause adverse effect to bonding intensity; (4) angle accuracy in joint cross section is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of processing mold that is used for transformer tank along sealing strip, and it can overcome above-mentioned shortcoming.
In order to achieve the above object, the utility model is solved by the following technical solutions: a kind of processing mold that is used for transformer tank along sealing strip, it is characterized in that, comprise upper die body and lower mold body, between upper and lower die body, form a rectangular channel, described width of rectangular equates that with sealing strip described upper die body has the saw kerf that becomes angle with described rectangular channel cross section, at the bottom of this saw kerf direct through groove.
Described saw kerf is two, and with respect to described rectangular channel cross section symmetry.
Obviously, utilize this Mould Machining sealing strip joint cross section, lower to operator's specification requirement; The operator can not hurt hand in this work; Joint cross section angle accuracy height; And bonding sealing strip can be fixed on heating, drying in the mould, helps to guarantee bonding quality.
Description of drawings
Fig. 1 is the front view of specific embodiment of the utility model;
Fig. 2 is the vertical view of specific embodiment of the utility model;
Fig. 3 is the left view of specific embodiment of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, mould comprises upper die body 1 and lower mold body 2, fix by nine screw rods 3 and wing nut 4 butt joints in upper die body 1, lower mold body 2, offer a rectangular channel 5 between upper die body 1, the lower mold body 2, described rectangular channel 5 width equate with sealing strip.An end of offering 6, two saw kerfs 6 of two saw kerfs at upper die body 1 overlaps, and with respect to described rectangular channel 5 cross section symmetries, at the bottom of the direct through groove.
When making the sealing strip joint, the two ends of sealing strip are fixed in the rectangular channel 5, hacksaw just can process sealing strip joint cross section by saw kerf 6, and direction can freely be selected.The height of rectangular channel 5 can also be 1 times, 2 times or many times of sealing strip thickness, makes a plurality of sealing strip joints simultaneously to adapt to.There is certain roughness in the joint cross section that utilizes hacksaw to process, and is favourable to bonding intensity.
Obviously, utilize this Mould Machining sealing strip joint cross section, lower to operator's specification requirement; The operator can not hurt hand in this work; Joint cross section angle accuracy height; And bonding sealing strip can be fixed on heating, drying in the mould, helps to guarantee bonding quality.
Claims (2)
