Description
Technical field
The present invention relates to high-frequency welded steel pipe mouth of pipe processing unit (plant), refer to particularly a kind of pipe end groove topping machanism.
Background technology
Pipe end finished edge is the manufacturing procedure that must implement in petroleum gas, slurry conveying steel pipe are produced, and bevel angle is generally 30 ~ 35 °.The blade of pipe end process equipment of the prior art---plain-end chamfering machine is fixed in the insert groove of offering in knife bar, and insert groove has certain angle of inclination, and the angle design between processing sword and the axis of knife bar of blade is 32.5 °.Along with the variation of product development and the market demand, having in recent years part industry to require pipe end slope-mouth in the design of application steel pipe is 38 °, 40 ° and 45 °, and 32.5 ° of groove bite lever apparatus in existing equipment only can be by change the angle between blade and knife bar axis at the pad of placing by force different-thickness between blade and insert groove, to realize the processing of 38 ~ 40 ° of pipe end slope-mouths.If but the pipe end slope-mouth angle that needs processing is enlarged to 45 ° and high angle more, continue to place by force the pad that thickness is thicker between blade and insert groove, the impulse stroke of former knife bar and device, installation site are seriously limited, knife bar cannot bear so large cutting force, also cannot realize the processing work of pipe end slope-mouth.Therefore, for meeting the processing request of user to steel tube head bevel angle, need improve steel tube head groove topping machanism of the prior art, in order to realize the more pipe end slope-mouth angle processing of high angle.
Summary of the invention
Object of the present invention is exactly the deficiency that will solve above-mentioned background technology, provides a kind of user of meeting to process the pipe end groove topping machanism that more senior executive holds bevel angle to require.
For achieving the above object, technical scheme of the present invention is: a kind of pipe end groove topping machanism, comprise knife bar, on described knife bar, offer the insert groove of triangle, in described insert groove, lay the blade of triangle, described blade is fixed in insert groove by pressing plate and trip bolt, it is characterized in that: between described blade and insert groove, be provided with the gap for blade rotation, included angle adjustable A=32.5 ~ 47.5 ° between processing sword and the knife bar axis of described blade, the processing blade tip end of described blade stretches out the horizontal range L=0 ~ 8mm of knife bar.
In such scheme:
The bottom of described insert groove is skewed, thereby can regulate angle A and horizontal range L by rotating described in the position adjustments of moving blade.
Between described blade and insert groove, be provided with pad, described pad is fixed on insert groove by attachment screw, thereby can regulate described rotation to regulate angle A and horizontal range L by changing the pad of different-thickness.
Described blade is equilateral triangle shape, all offers processing sword on its every limit, blade wherein processing sword when infringement of one side like this, and can continue the processing sword on all the other limits that use this blade, and not need the blade more renewing, save material.
The present invention improves and forms on the basis of 32.5 ° of knife bar sizes, can realize the angle between processing sword and the axis of knife bar that changes blade by two kinds of modes:
One,, by set up the different pad of thickness between blade and insert groove, realize angle between processing sword and the axis of knife bar of blade between 32.5 ~ 40 °;
Two, direct rotating blade, make the angle between processing sword and the axis of knife bar of blade increase or reduce, fix blade by adjusting compressing tablet in clamping device and the relative position of screw more subsequently, this mode can realize the variation in any range (comprise 32.5 ~ 47.5 ° and more high angle) of angle between processing sword and the axis of knife bar of blade.
The present invention can meet the demand of the machining angle of client to steel tube head, is a kind of pipe end groove topping machanism that can win more market order for enterprise, create more economic benefit.

Fig. 1 is a kind of three-dimensional assembly structure schematic diagram of pipe end groove topping machanism;
Fig. 2 is the stereo decomposing structural representation of the topping machanism of groove shown in Fig. 1.
Fig. 3 is the main TV structure schematic diagram of the topping machanism of groove shown in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
In this description, for sake of convenience, by knife bar be laterally made as directions X, vertically to being made as Y-direction.
A kind of pipe end groove topping machanism as shown in Figure 1 and Figure 2, it is to improve and form on the basis of 32.5 ° of knife bar sizes, it comprises knife bar 1, on knife bar 1, offer the insert groove 3 of triangle, in insert groove 3, lay the blade 2 of triangle, blade 2 is fixed in insert groove 3 by pressing plate 4 and trip bolt 5, between blade 2 and insert groove 3, be provided with the gap of rotating for blade 2, blade 2 clamped fixing before, blade 2 can carry out the rotation of certain angle in insert groove 3.In the present embodiment, blade 2 is equilateral triangle shape, all offers processing sword 2.1 on its every limit, the wherein processing sword 2.1 of one side while damaging of blade 2 like this, can continue the processing sword 2.1 on all the other limits that use this blade 2, and not need the blade 2 more renewing, save material.In the present embodiment, included angle adjustable A=32.5 ~ 47.5 ° between processing sword 2.1 and knife bar 1 axis of the blade 2 cutting for steel pipeline groove, the horizontal range L=0 ~ 8mm of knife bar 1 is stretched out at processing sword 2.1 tips of blade 2.
In the present embodiment, the bottom of insert groove 3 is skewed, thereby can be rotated and be regulated angle A and horizontal range L by the position adjustments of moving blade 2.
Between blade 2 and insert groove 3, be provided with pad 7 in addition, pad 7 is fixed on insert groove 3 by attachment screw 6, thereby can regulate rotation to regulate angle A and horizontal range L by the pad 7 of changing different-thickness.
In the present embodiment, angle between the processing sword 2.1 of blade 2 and knife bar 1 axis is made as 35 ~ 47.5 °, and it is to obtain with the angle A adjustment of the axis of knife bar 1 by the overhang L of the processing sword 2.1 of the central point position B of the screw hole position C to trip bolt 5, blade 2 on the basis 32.5 ° of knife bar sizes, blade 2 and processing sword 2.1.
Be specially:
As shown in Figure 3, take the lower extreme point D of the blade 2 away from former 32.5 ° of knife bars as basic point, angle between the processing sword 2.1 of blade 2 and the axis of knife bar 1 rotates 2.5-15 ° of scopes on the basis of 32.5 ° of knife bar sizes, process included angle A=35 ~ 47.5 ° between sword 2.1 and the axis of knife bar 1, accordingly, horizontal range L=0 ~ the 8mm of knife bar 1 is stretched out at processing sword 2.1 tips of blade 2, the central point position B of blade 2 is provided with X-axis 0 ~ 7mm on the basis of 32.5 ° of knife bar sizes, the skew of axially-2 ~ 1mm, the screw hole position C of trip bolt 5 is provided with radially 0 ~ 1mm on the basis of 32.5 ° of knife bar sizes, the skew of axial 0 ~ 7mm.
By above-mentioned a series of adjustment that 32.5 ° of original knife bars are carried out, can obtain the pipe end groove topping machanism topping machanism of a kind of 35 ~ 47.5 °, and it does not change the basic structure of former knife bar, be easy to realize, processing is simple.
Pipe end groove topping machanism after improvement, can meet the demand of the machining angle of client to steel tube head, is a kind of pipe end groove topping machanism that can win more market order for enterprise, create more economic benefit.
