Description
Technical field
The utility model is related to arrive a kind of terminal clamp, the terminal clamp especially used in fysed flux.
Background technology
The original terminal clamp of fysed flux there are many defects：First, too heavy, each net weight up to 100 kilograms with
On, the heavy burden of electrode positioning mechanism has been aggravated, has been easy to be out of order.Second is that collet tube wall is too thick, ore in sand form is easily retained on top end face, works as pine
Open ace's bolt lengthen electrode when, ore in sand form can be fallen between electrode and collet inner wall, prevent electrode with collet from being in close contact, because connecing
It touches bad and discharges and burn out collet inner wall, entire collet is caused to scrap.Third, ace's bolt directly reinforces on the electrode, because of contact surface
Few, fastening force is big, easily break electric pole.Fourth, ace's bolt and electrode contact surface are small, ace's bolt local current is too big, because of discharge electrode
Easy burn-out will renew ace's bolt in 2-3 days.Fifth, former collet cannot meet present production and equipment requirement at all, change within 2-3 days
Ace's bolt changes electrode and collet in 1-2 months, not only increases repair and production cost, but also reduce the serviceability rate of equipment, also increase
Maintenance load, so, develop new collet extremely urgent.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of can make that electrode and collet are in close contact, collet is not easy
It burns out, electrode is not easily broken, usage time is long, reduce production cost and mitigates a kind of terminal clamp of electrode weight itself.
To solve the technical problem, the technical solution adopted in the utility model is：
A kind of terminal clamp, including outer rim open a longitudinal openning, in the longitudinal direction in the longitudinal surface of the outer rim
The outer periphery of openning be welded into lock sleeve with steel plate, semicircle steel ring outer wall is connected with the inner wall that outer rim is in contact,
It is equipped with the first gap and the second gap between semicircle steel ring and semicircle kink, in the lower end of the outer rim close to semicircle
Movable half steel backing ring is equipped at shape kink, the front end of the movable half steel backing ring is equipped with protrusion, and ace's bolt is inserted into locking
In set.
The semicircle steel ring is higher by outer rim 15-30mm with semicircle kink.
The end of the semicircle steel ring the raised area is slope-shaped.
The end of the semicircle kink the raised area is slope-shaped.
The outer surface of the outer rim is equipped with reinforcing rib.
The outer rim thickness of pipe wall 10mm -20mm.
The semicircle steel ring is 10mm -20mm with semicircle kink thickness of pipe wall.
The lock sleeve is square taper.
The wide 22mm of openning of the outer rim longitudinal surface.
The utility model has the beneficial effects that：
1, semicircle steel ring outer wall is connected with the inner wall that outer rim is in contact, and electrode is enable to be in close contact with collet,
Because electrode contacts completely with collet without easy burn-out collet inner wall, the usage time of collet is substantially prolonged.
2, ace's bolt, which directly reinforces, gives semicircle kink, electrode is transmitted the force to again after semicircle kink stress, because of semicircle
Shape kink is greatly increased with electrode contact surface, electrode uniform force, in this way, electrode is not easily broken.
3, terminal clamp not easy burn-out, reduces repair and production cost.
4, the terminal clamp of the utility model alleviates many than original mold collet in weight.

Specific implementation mode
Referring to Fig. 1-3：A kind of terminal clamp, including outer rim 1 open a longitudinal mouth in the longitudinal surface of the outer rim 1
Son 11 is welded into lock sleeve 2 in the outer periphery of longitudinal openning 11 with steel plate, and 4 outer wall of semicircle steel ring is in contact with outer rim 1
Inner wall be connected, the first gap 6 and the second gap 7 are equipped between semicircle steel ring 4 and semicircle kink 3, in outer rim 1
Lower end movable half steel backing ring 8 is equipped at semicircle kink 3, the front end of movable half steel backing ring 8 is equipped with protrusion
81, ace's bolt 5 is inserted into lock sleeve 2.
Semicircle steel ring 4 is higher by outer rim 115-30mm with semicircle kink 3.
The end slope-shaped 41 of 4 the raised area of semicircle steel ring.
The end slope-shaped 31 of 3 the raised area of semicircle kink.
The outer surface of outer rim 1 is equipped with reinforcing rib.
1 thickness of pipe wall 10mm -20mm of outer rim.
Semicircle steel ring 4 is 10mm -20mm with semicircle 3 thickness of pipe wall of kink.
Lock sleeve 2 is square taper.
The 11 width 22mm of openning of 1 longitudinal surface of outer rim.
Terminal clamp production method：
1, the seamless steel pipe of internal diameter 210mm is selected to make inner tube, inner tube wall thickness is preferably 15mm, no 10mm can also, by this
Inner tube is cut into 200mm long, and is sawn into 2 half from centre, as semicircle kink, then half steel ring therein is prescinded 10mm
The rust of steel ring inner wall is thoroughly eliminated totally with sand favourable turn.
2, the steel pipe for selecting internal diameter bigger 50-60mm than the seamless steel pipe diameter of internal diameter 210mm selects internal diameter 260mm-
The seamless steel pipe of 270mm makees outer tube, and outer tube wall thickness is preferably 15mm, without 10mm also can, opened in the side of outer tube one wide
The openning of 22mm, it is fixed with the steel plate of 16-20mm weldering, one side's taper lock on the outside of this openning, on the fixed opposite of square taper lock
The semicircle steel ring sleeve of inner tube is welded on the inner wall of outer tube by inside, and the semicircle steel ring of inner tube is higher by outer steel pipe 20mm, high
The upper end for going out part is cut into slope shape outward.
3, semicircle kink outer wall welds the round steel of 2 root long 100mm diameters 10mm, is sleeved in the steel-tube seat of internal diameter 12mm,
Steel-tube seat fixation is welded in the fixed both sides of taper lock, in this way, semicircle kink can flexibly be unclamped in loose unloading electrode and
It falls.
4, semicircle kink coordinates ace's bolt fastening electrode.
5, the roads outer steel pipe peripheral surface weldering 2-3 reinforcing rib.If the pipe thickness of outer steel pipe reaches 20mm, there is no need to weld reinforcing rib
.
In addition, outer steel pipe locking running-on bottom end weldering half circle steel ring support can also be used, semicircle steel ring support front end has
Protrusion holds semicircle kink with this half steel ring support, prevents from falling when loose electrode.
