Abstract
The invention relates to a velocity measurement device for a metal tube processing unit, which is characterized by comprising a velocity measurement wheel, wherein the velocity measurement wheel is provided with a pressure device for maintaining preset contact force between the velocity wheel and the outer surface of a metal tube to be processed; the pressure device can enable the velocity measurement to synchronously rotate with the metal tube under the action of the axial movement of the metal tube so as to measure the axial movement velocity of the metal tube; and a cutting device in the metal tube processing unit is used for cutting the metal tube based on the axial movement velocity of the metal tube measured by the velocity measurement wheel. In the invention, as the velocity measurement device can reflect the axial movement speed of the metal tube in the cutting device synchronously, the welding processing velocity and the cutting velocity can be maintained to be synchronous, thus avoiding metal tube deformation due to two desynchronized velocities.
Description
Technical field
The present invention relates to a kind of speed measuring device, particularly relate to a kind of speed measuring device that is used for metal tube processing unit.
Background technology
The metal tube that thin-walled has the longitudinal seam welding is widely used tubing, and wherein, the forming strap of pulling out from feed reel is a skelp, promptly forms a pipe with seam earlier, with welding means such as laser instruments its longitudinal seam welding is got up then.This metal tape, for example stainless steel band is configured as a pipe that has longitudinal joint gradually by forming tool, and through after the welding machine, the pipe that welding is good enters a cooling tube with big gap, cools off strongly with oxygen at this pipe inside weld; Carrying out weld seam then handles; At last the good cuts in metallic pipe of welding is become Len req.
Yet the speed between weld seam of the prior art is handled and cut is difficult to carry out Synchronization Control, when the speed of weld seam processing is asynchronous with speed of cut, can cause the metal tube distortion.
Summary of the invention
The purpose of this invention is to provide a kind of can be in the metal tube manufacture process, butt welded seam processing speed and speed of cut are carried out synchronously, and can prevent because the asynchronous measurement mechanism that causes metal tube distortion of described two speed.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of speed measuring device that is used for metal tube processing unit is characterized in that: comprise fifth wheel; Also be provided with the device for exerting that is used for the outer surface of described fifth wheel and metal tube to be processed is kept predetermined contact force on the described fifth wheel, described device for exerting makes described fifth wheel under the effect of the axially-movable of metal tube, make described fifth wheel and metal tube take place to rotate synchronously, thereby record the axially-movable speed of described metal tube; Cutting means in the described metal tube processing unit cuts operation according to described fifth wheel with the described axially-movable speed that it records.
Speed measuring device among the present invention goes owing to the axially-movable speed of metal tube 1 synchronously being reacted in the cutting means, soldering speed and speed of cut are kept synchronously, thereby avoid because the asynchronous metal tube that causes of described two speed is out of shape.
Description of drawings
Fig. 1 is the structural representation of the measurement mechanism among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 1 shows the structural representation of the speed measuring device among the present invention.As shown in Figure 1, the speed measuring device among the present invention comprises fifth wheel 3, cylinder 4 and at least one pair of driving wheel 2.
As shown in Figure 1, described fifth wheel 3 is speed measuring coders, also can be a roller, and the output shaft of described roller is connected with speed measuring coder; The edge of described fifth wheel 3 has the joint portion that can match with the outer surface of metal tube 1 to be processed, preferably, described joint portion forms the groove complementary mutually with the outer surface of described metal tube 1, and described groove is formed at least a portion of described joint portion.Also be provided with on the described fifth wheel 3 and be used for the joint portion of described fifth wheel 3 and the outer surface of described metal tube 1 are kept being scheduled to the device for exerting of contact force, described device for exerting can drive described fifth wheel 3 surveying near or away from the motion of the direction of metal tube 1, when driving described fifth wheel 3 to direction near metal tube 1, the outer surface of its joint portion that can make fifth wheel 3 and metal tube 1 contacts under the predetermined situation that contacts pressure keeping, thereby make described fifth wheel 3 under the effect of the axially-movable of metal tube 1, with described metal tube 1 rotation synchronously taking place, thereby records the axially-movable speed of metal tube 1.Preferably, described device for exerting is oil cylinder or cylinder 4, can certainly be screw rod.Preferably, described device for exerting is set on the installing rack 5.
As shown in Figure 1, axially-movable takes place in described metal tube 1 under the effect of at least one pair of driving wheel 2, simultaneously, the relative clamping part that is formed with of described every pair of driving wheel 2, preferably, described clamping part forms the complementary mutually groove of outer surface of described metal tube, and metal tube 1 is under the effect of the clamping part of described at least one pair of driving wheel 2, can make metal tube 1 that axially-movable takes place on the one hand, also have moulding function on the other hand metal tube 1.Further, described each be removable to driving wheel 2, thereby be adapted to process the metal tube of different-diameter or shape, especially, every pair of driving wheel 2 also is provided with the distance adjusting means that is used to adjust spacing between described every pair of driving wheel 2, so that adapt to the metal tube of different-diameter or shape.
In addition, described speed measuring device also has signal output interface, it is used for the axially-movable speed of fifth wheel 3 detected metal tubes 1 is sent in the control device and/or cutting means of metal tube processing unit, described control device will cut action by device according to the described sanction of axially-movable speed command of its described metal tube 1 that receives, and perhaps described cutting means directly cuts action voluntarily according to the axially-movable speed of its described metal tube of receiving 1.
Speed measuring device among the present invention goes owing to the axially-movable speed of metal tube 1 synchronously being reacted in the cutting means, soldering speed and speed of cut are kept synchronously, thereby avoid because the asynchronous metal tube that causes of described two speed is out of shape.
