Description

Alignment frock of overlength pipe target

Technical Field

The utility model relates to the technical field of tube targets, in particular to an alignment tool for an ultra-long tube target.

Background

The molybdenum and molybdenum alloy tube target is a large-diameter molybdenum tube blank prepared by a powder metallurgy method, and is a large-class molybdenum metal deep-processing product with high added value and high technical content which is formed by subsequent extrusion, forging or isostatic pressing processing. Because of the high melting point, high conductivity, lower specific resistance, better corrosion resistance and good environmental protection performance, the film can be formed on various base materials, and can be widely applied to electronic components and electronic products, such as TFT-LCD (thin film semiconductor-liquid crystal display), plasma display screen, solar cell, heat shield and the like which are widely applied at present.

Because the tubular target is relatively slender, the straightness of the molybdenum tube target is insufficient due to deformation after shrinkage, and the ultra-long molybdenum tube target is more so. However, the straightness of the molybdenum tube target directly affects the life and safety of the product. However, the straightness of the pipe target is difficult to control in the existing pipe target production technology.

Referring to fig. 1, the utility model provides an alignment tool for an ultra-long tube target, which comprises an extrusion device 1, a clamping device 2, a supporting device 3 and a transferring device 4.

Specifically, referring to fig. 1 and 2, the pressing device 1 includes a movable portion 11, a fixed portion 12, and a first driving assembly 14. The movable portion 11 includes an upper plate 111, and the upper plate 111 has a rectangular shape and a first elliptical surface 112 is formed on the lower side thereof. The fixing portion 12 includes a lower plate 121, and the lower plate 121 has a rectangular shape and a second elliptical surface 122 is formed on the upper side thereof.

In other embodiments of the present utility model, the first and second ellipses 112 and 122 are symmetrical in shape, and the shapes of the upper and lower plates 111 and 121 are not limited to those shown in the drawings, and the shapes of the two may be changed accordingly according to the installation requirements thereof.

The extrusion device 1 has two states: an anastomotic state and a detached state. In the fitted state, the movable portion 11 is abutted against the fixed portion 12, the first elliptical surface 112 is abutted against the second elliptical surface 122 to form the alignment hole 13, and in the separated state, the movable portion 11 is separated from the fixed portion 12. The movable portion 11 is connected to the first driving assembly 14, and the first driving assembly 14 drives the movable portion 11 to switch the pressing device 1 between the anastomotic state and the detached state.

The axis of the tube target 5 is parallel to the alignment hole 13, the long axis of the alignment hole 13 is perpendicular to the axis of the tube target 5, the length of the long axis is greater than the diameter of the tube target 5, and the length of the short axis is less than the diameter of the tube target 5.

Specifically, the first driving component 14 drives the movable portion 11 to move toward the fixed portion 12, and when the movable portion 11 is abutted against the fixed portion 12, the extrusion device 1 is in an anastomotic state. When the first driving assembly 14 drives the movable portion 11 away from the fixed portion 12, the pressing device 1 is in a separated state.

The function of the pressing device 1 is to restore the bent portion of the tube target 5 to a straight shape by pressing the movable portion 11 and the fixed portion 12. Since the length of the short axis of the alignment hole 13 is smaller than the diameter of the tube target 5, the tube target 5 is pressed in the short axis direction of the alignment hole 13 to restore straightness. And because the length of the long axis is greater than the diameter of the tubular target 5, a gap exists between the tubular target 5 and the inner wall of the straightening hole 13 in the long axis direction of the straightening hole 13, and when the tubular target 5 is extruded, the gap between the tubular target 5 and the inner wall of the straightening hole 13 can accommodate deformation of the tubular target 5 caused by extrusion, so that the tubular target 5 is prevented from being broken.

The short axis length of the straightening hole 13 is smaller than the diameter of the tube target 5, but the short axis length of the straightening hole 13 is too small to adversely affect the performance of the tube target 5 after the extrusion of the straightening hole 13, and therefore, it is preferable that the short axis length of the straightening hole 13 is smaller than the diameter of the tube target 5 by 1mm to 2mm, for example, 1mm, 1.5mm, 2mm.

More specifically, the first drive assembly 14 employs a hydraulic machine having a platen and a base, the platen being movable toward and away from the base during operation of the hydraulic machine. The movable part 11 of the pressing device 1 is mounted on the platen by bolts, and the fixed part 12 is mounted on the base by bolts.

In other embodiments of the present utility model, the first driving assembly 14 may further use a cylinder, an oil cylinder, or the like to drive the movable portion 11.

The working principle of the extrusion device 1 is as follows: before alignment, the tube target 5 is placed on the fixed part 12 of the pressing device 1. When the alignment is performed, the movable part 11 is driven to move towards the fixed part 12 by the pressure plate of the hydraulic machine, the pipe targets 5 are aligned until the movable part 11 is in butt joint with the fixed part 12, and then the movable part 11 is driven to be far away from the fixed part 12 by the pressure plate of the hydraulic machine. Finally, the worker rotates the tube target 5 by 90 ° around its own axis, and then straightens the tube target 5, or moves the tube target 5 in its own axis direction, and then straightens the other portions of the tube target 5.

Compared with the round straightening holes 13, the straightening holes 13 are elliptical, the length of the long axis is larger than the diameter of the tube targets 5, the length of the short axis is smaller than the diameter of the tube targets 5, and the tube targets 5 can be prevented from being broken while the tube targets 5 are straightened.

Referring to fig. 1 and 3, the clamping device 2 includes a locking member 21 and two semicircular clamping heads 22, the two clamping heads 22 are abutted to form a clamping hole 23 for clamping the tube target 5, and the two clamping heads 22 are locked by the locking member 21.

Specifically, the clamping heads 22 are semicircular, the clamping holes 23 formed after the two clamping heads 22 are butted are circular, and the pipe targets 5 penetrate through the clamping holes 23 and are locked by the locking pieces 21. In this embodiment, the locking member 21 is a bolt, the bolt is mounted on one of the chucks 22, the other chuck 22 is provided with a thread, and the bolt penetrates the thread and is screwed, so that the locking of the tubular target 5 can be realized.

The clamping device 2 functions in addition to clamping the tube target 5, the operator also needs to rotate or feed the tube target 5 through the clamping device 2. Thus, in order to facilitate the rotation or feeding of the tube targets 5 by the staff, the side of each collet 22 facing away from the clamping hole 23 is provided with a handle 24, the handle 24 being fixed to the corresponding collet 22 by means of welding.

Referring to fig. 1 and 4, since the length of the tube target 5 is long, the portion between the pressing device 1 and the clamping device 2 is easily bent or even broken due to gravity, and the supporting device 3 supports the portion of the tube target 5 to prevent the portion from breaking.

Specifically, the supporting device 3 is disposed between the pressing device 1 and the clamping device 2, and includes a frame 31 and a lifting assembly 35, and the frame 31 is detachably mounted on the lifting assembly 35.

More specifically, the frame 31 is made of square hollow section, the axis of the length direction of the frame is perpendicular to the axis of the tube target 5, and when the tube target 5 is placed on the frame 31, the lifting assembly 35 drives the frame 31 to lift, so as to drive the tube target 5 to lift.

When the tube target 5 is fed in the own axis direction, friction between the tube target 5 and the holder 31 easily causes the tube target 5 to be worn. In order to reduce the abrasion to the tube targets 5, the first roller 32 is mounted on the frame 31, and the axis of the first roller 32 is parallel to the longitudinal direction of the frame 31. The pipe target 5 is placed on the first roller 32, so that the friction force applied to the pipe target 5 during feeding is changed from larger sliding friction to smaller rolling friction, and the abrasion applied to the pipe target 5 during feeding is greatly reduced. Preferably, the first roller 32 is made of rubber.

In addition, when deviation occurs in the feeding direction in which the tube target 5 is fed in the direction of its own axis, or in the rotation axis along which the tube target 5 rotates, the tube target 5 may be caused to slip off the holder 31, resulting in bending or even breaking of the tube target 5.

In order to prevent the tube targets 5 from slipping off the frame 31, two limiting posts 33 are arranged side by side on the frame 31. The limiting posts 33 are welded vertically to one side of the frame 31 near the tube target 5, that is, one side of the frame 31 where the first roller 32 is mounted, and a limiting groove is formed between the two limiting posts 33 and the first roller 32. The tube target 5 passes through the limiting groove, and the axis of the tube target 5 is restrained in the limiting groove.

In some other embodiments of the utility model, one of the two stopper posts 33 is not perpendicular to the side of the frame 31 that is adjacent to the tube target 5, or neither stopper post 33 is perpendicular to the side of the frame 31 that is adjacent to the tube target 5. The included angle between the two spacing posts 33 can be an acute angle, a right angle or an obtuse angle, only the opening for the pipe target 5 to enter the spacing groove is required to be reserved between one ends of the two spacing posts 33 far away from the frame body 31, and the spacing groove can prevent the pipe target 5 from slipping from the frame body 31.

When the limiting groove restrains the axis of the tube target 5, the tube target 5 inevitably generates friction with the limiting post 33, and is worn. Therefore, each limiting column 33 is coaxially sleeved with a second roller 34, and the second rollers 34 can freely rotate around the axis of the second roller. The second roller 34 converts sliding friction between the tube target 5 and the stopper post 33 into rolling friction, thus reducing wear to which the tube target 5 is subjected.

The lifting assembly 35 can adopt a lifting machine such as a forklift and a lifter, in this embodiment, the lifting assembly 35 adopts a forklift, and since the frame 31 is made of square hollow sections, the frame 31 has a connecting slot 311, and the fork of the forklift can drive the frame 31 to lift after being inserted into the connecting slot 311, so as to drive the pipe target 5 thereon to lift.

The number of the support devices 3 may be increased according to the length of the tube targets 5 to be supported. When the number of the supporting means 3 is plural, the plural supporting means 3 are spaced apart in the axial direction of the tube target 5. The figure shows the situation when the number of support means 3 is two.

Referring to fig. 5, the tube targets 5 are heated to a desired temperature in a high temperature furnace before being aligned, and thus the tube targets 5 are transferred from the high temperature furnace to the supporting means 3 before being aligned. The transfer device 4 serves to transfer the tube targets 5 to the support device 3.

In particular, the transfer device 4 comprises a transfer frame 41 and a second drive assembly 42, the transfer frame 41 having a projection 411, the projection 411 being able to penetrate into the tube target 5. The carriage 41 is detachably mounted on the second driving assembly 42, and the second driving assembly 42 drives the carriage 41 to move and drives the tube target 5 to move through the protrusion 411.

More specifically, the transfer frame 41 is made of a hollow square profile, a long tube having a cylindrical shape is welded to a side surface thereof, the length of the long tube is longer than that of the transfer frame 41, and the protruding portion 411 is formed by a portion of the long tube protruding from the transfer frame 41. Since the tube target 5 is hollow cylindrical, the protruding portion 411 penetrates into the tube target 5 and then moves the tube target 5.

The second driving component 42 may be a forklift, a mechanical arm, or the like, and in this embodiment, the second driving component 42 is a forklift. Because the transportation frame 41 is made of hollow square sectional materials, the insertion holes 412 are formed in the transportation frame, the fork of the forklift is inserted into the insertion holes 412, the protruding parts 411 penetrate into the pipe targets 5, and the forklift can drive the transportation frame 41 to move so as to drive the pipe targets 5 to move.

The utility model provides an implementation principle of an ultralong tube target straightening tool, which comprises the following steps:

before straightening, the movable part 11 of the extrusion device 1 is firstly arranged on a pressure plate of the hydraulic machine, and the fixed part 12 of the extrusion device 1 is arranged on a base of the hydraulic machine. The tube target 5 is then heated in a high temperature furnace to the temperature required for straightening.

After the heating is completed, the transport frame 41 is mounted on the fork of the forklift through the insertion hole 412 on the transport frame 41, the protruding part 411 of the transport frame 41 is penetrated into the pipe target 5 in the high-temperature furnace, and then the pipe target 5 is moved out of the high-temperature furnace through the forklift and placed on the supporting frames respectively mounted on the fork of the other two forklifts. The fork truck corresponding to the support frame descends the fork, so that one end of the pipe target 5, which is far away from the transportation frame 41, descends to the second arc-shaped surface of the fixing part 12, and finally the fork of the fork truck corresponding to the transportation frame 41 withdraws from the jack 412 of the transportation frame 41, and the worker installs the clamping device 2 on one end of the pipe target 5, which is far away from the extrusion device 1.

When the alignment is performed, the movable part 11 is driven to move towards the fixed part 12 by the pressure plate of the hydraulic machine, the pipe targets 5 are aligned until the movable part 11 is in butt joint with the fixed part 12, and then the movable part 11 is driven to be far away from the fixed part 12 by the pressure plate of the hydraulic machine. Finally, the worker rotates the tube target 5 around its own axis, then straightens the tube target 5, or moves the tube target 5 in its own axis direction, then straightens the other portion of the tube target 5.

According to the alignment tool for the ultra-long tube targets, provided by the utility model, the movable part 11 is driven to move by the hydraulic press, so that the alignment of the tube targets 5 can be efficiently carried out. And the transfer device 4 and the supporting device 3 are used for efficiently preparing before straightening, so that the whole work efficiency of straightening the riser target 5 is improved. And the staff can conveniently feed or rotate the pipe target 5 through the clamping device 2, so that the work efficiency of the whole alignment of the pipe target 5 is further improved.

In addition, the oval design of the straightening groove can effectively reduce the situation that the pipe target 5 is extruded and broken during straightening, and the first roller 32 and the second roller 34 arranged on the supporting device 3 can effectively reduce the abrasion of the pipe target 5 during feeding, so that the working quality of straightening the pipe target 5 is improved.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model.
