Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical field, concretely is the tendon traction straightening machine and tendon processing equipment. BACKGROUND

[0002] Steel bar processing is an indispensable link in reinforced concrete engineering or prestressed concrete engineering. In the steel bar processing process, traction and straightening are key steps, and the purpose is to provide accurate positioning and support for subsequent cutting, end upsetting and other processes. At present, the traction and straightening of steel bars are mainly completed by traction straightening machines.

[0003] A commonly used traction straightening machine at present usually includes the following structure: a fixed shaft provided with a driven traction wheel is installed on a rack through a bearing, and a driving traction wheel is installed on the rack and driven by a motor. A tendon channel for the steel bar to pass through is formed between the driven traction wheel and the driving traction wheel. In the steel bar traction process, the driven traction wheel presses the steel bar so that it is positioned between the driven traction wheel and the driving traction wheel, and the motor drives the driving traction wheel to rotate, thereby driving the steel bar to move forward.

[0004] However, the existing traction straightening machine has the following problems in actual application:

[0005] 1. Limited traction range: since the fixed shaft of the driven traction wheel is installed on the rack through a bearing, and the size of the tendon channel between the driven traction wheel and the driving traction wheel is fixed, the device can only be applied to steel bars of a specific size, and cannot meet the traction needs of steel bars of different sizes, with low practicality.

[0006] 2. Performance degradation due to wear: after the traction straightening machine is used for a period of time, the outer surfaces of the driven traction wheel and the driving traction wheel in contact with the steel bar will be worn, causing the gap between them to increase. This wear will cause the driven traction wheel to be unable to effectively press the original size of the steel bar, thereby being unable to stably traction the original size of the steel bar, making it difficult to play a traction role and affecting the normal use of the device.

[0007] Therefore, there is an urgent need for an improved traction straightening machine that can solve the above problems, which is a technical problem to be solved by those skilled in the art. UTILITY MODEL CONTENTS

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0040] Example 1

[0041] like Figures 1-7 As shown, this embodiment provides a rib traction and straightening machine, which includes: a frame 1, at least one traction wheel set 2, a drive mechanism 3, and an adjustment mechanism 4. The traction wheel set 2 includes an active traction wheel 21 mounted on the frame 1 and a driven traction wheel 23 mounted on a sway shaft 22. A rib channel is formed between the active traction wheel 21 and the driven traction wheel 23. The drive mechanism 3 is connected to the active traction wheel 21. The sway shaft 22 is hinged to the frame 1. The adjustment mechanism 4 adjusts the sway angle of the sway shaft 22 relative to the frame 1 to adjust the distance between the active traction wheel 21 and the driven traction wheel 23.

[0042] In detail, the adjusting mechanism 4 adjusts the swing amplitude of the swing shaft 22, thereby controlling the driven traction wheel 23 on the swing shaft 22 to move closer to or further away from the driving traction wheel 21. This allows the distance between the driven traction wheel 23 and the driving traction wheel 21 to be adjusted within a certain range, meaning the size of the reinforcing bar channel can be adjusted within a certain range. This enables the straightening of reinforcing bars 9 of different diameters, offering greater flexibility and practicality, and overcoming the limitation of existing technologies that can only straighten reinforcing bars 9 of a specific diameter. Furthermore, it overcomes the defect that wear between the driving traction wheel 21 and the driven traction wheel 23 can widen the gap, making it impossible to straighten reinforcing bars 9 of the original size.

[0043] Furthermore, there are two sets of traction wheel sets 2. There are two yaw shafts 22, each with a driven traction wheel 23 installed on it. The two yaw shafts 22 are arranged side by side with intervals and connected by a connecting rod 25. The adjusting mechanism 4 is installed on the frame 1 and is connected to the connecting rod 25 in a transmission manner. The two active traction wheels 21 are arranged one-to-one with the two driven traction wheels 23 and are respectively installed on a rotating shaft 24. The two rotating shafts 24 are connected to the drive mechanism 3 in a transmission manner.

[0044] In detail, such as Figures 3-6As shown, the two rotating shafts 24 of the embodiment are respectively installed on the rear plate 14 of the frame 1 through the mounting seats 27 at the two axial ends thereof, the two deflection shafts 22 are connected to form a whole through the connecting rod 25, and the adjusting mechanism 4 is connected to the connecting rod 25, so that the adjusting mechanism 4 can simultaneously adjust the spacing between the driven traction wheels 23 and the corresponding driving traction wheels 21 in the two groups of traction wheel sets 2, and the reinforcement 9 is pulled through the two groups of traction wheel sets 2 in sequence, so that the pulling and straightening effect on the reinforcement 9 is better.

[0045] Further, in order to realize the driving of the two driving traction wheels 21 by the driving mechanism 3, the two rotating shafts 24 are respectively provided with transmission wheels, the two transmission wheels are connected through a chain 26 or a belt, one of the rotating shafts 24 is connected to the output end of the driving mechanism 3, or the two rotating shafts 24 are respectively provided with slave transmission gears, the driving mechanism 3 is provided with a master transmission gear, one of the slave transmission gears is meshed with the master transmission gear, and the other slave transmission gear and the master transmission gear or one of the slave transmission gears are connected through a reversing gear.

[0046] In detail, in the embodiment, the transmission relationship between the two rotating shafts 24 and the driving mechanism 3 can be selected according to actual needs, as long as the synchronous rotation of the two rotating shafts 24 can be realized. In other embodiments, the two rotating shafts 24 can be respectively driven to rotate by one driving mechanism 3.

[0047] Further, the adjusting mechanism 4 comprises a telescopic power source 46, a first connecting seat 41 connected to the output end of the telescopic power source 46, a second connecting seat 42 connected to the connecting rod 25, and the first connecting seat 41 and the second connecting seat 42 are hinged by a pin shaft 43. The telescopic power source 46 is a driving component capable of reciprocating along a straight line, which can be a pneumatic cylinder or an oil cylinder or an electric push rod, etc. In the embodiment, the telescopic power source 46 is a pneumatic cylinder, and the driving traction wheel and the driven traction wheel are arranged in the up-down direction, and correspondingly, the telescopic power source 46 can reciprocate along the up-down direction to drive the two swing shafts 22 to swing, so that the driven traction wheel 23 moves relatively towards the direction of approaching and moving away from the driving traction wheel 21, and the appropriate size of the reinforcing bar channel is adjusted to allow the reinforcing bar 9 to pass through smoothly and press the reinforcing bar 9. At this time, the driving mechanism 3 drives the rotating shaft 24 to rotate, and since the reinforcing bar 9 and the driving traction wheel 21 and the driven traction wheel 23 all have friction, the rotating shaft 24 rotates to drive the reinforcing bar 9 to move forward and straighten the reinforcing bar 9. In the embodiment, in the process of the telescopic power source 46 driving the swing shaft 22 to swing, since the telescopic power source 46 can only stretch and retract along the up-down direction, and the angle formed by the swing shaft 22 and the output shaft of the telescopic power source 46 changes with the swing angle of the swing shaft 22, and the first connecting seat 41 and the second connecting seat 42 are hinged by the pin shaft 43 in the embodiment, so that the swing shaft 22 can swing relative to the output end of the telescopic power source 46, and the required angle change amount during the swinging of the telescopic power source 46 and the swing shaft 22 can be met, avoiding the telescopic power source 46 also having to swing by the same angle during the swinging of the swing shaft 22, and avoiding interference with the swinging movement of the swing shaft 22, so that the swing shaft 22 swings smoothly.

[0048] Further, the driving traction wheel 21 and the driven traction wheel 23 are located in the rack 1, and the two ends of the reinforcing bar channel are exposed outside the rack 1.

[0049] In detail, the driving traction wheel 21 and the driven traction wheel 23 can be designed in the rack 1, or can be arranged outside the rack 1, preferably, the driving traction wheel 21 and the driven traction wheel 23 are designed in the rack 1, and only the reinforcing bar inlet and outlet at the two ends of the reinforcing bar channel are exposed outside the rack 1, avoiding interference of external factors with the traction and straightening process of the reinforcing bar 9, and also preventing the site staff from accidentally touching the driving traction wheel 21 and the driven traction wheel 23 and causing safety accidents.

[0050] Further, as shown in Figure 1 , Figure 7 , the rack 1 is provided with a strip-shaped hole 11 for adjusting the swing of the swing shaft 22, and the swing shaft 22 axially penetrates the strip-shaped hole 11.

[0051] In detail, in the process of straightening the reinforcing bar 9, the driven traction wheel 23 is easy to deviate during the process of moving away from and approaching the driving traction wheel 21, and thus affects the pressing of the reinforcing bar. In order to avoid this problem, as shown inFigure 1 , Figure 7 As shown, a strip hole 11 is provided on the front plate 13 of the frame 1 to control the yaw shaft 22 to yaw in a specific direction.

[0052] Furthermore, such as Figure 1 , Figure 2 As shown, the frame 1 is provided with an inlet groove 12 to facilitate the introduction of reinforcing bars into the reinforcing bar channel.

[0053] In detail, the guide groove 12 is a through hole, which is used to facilitate the introduction of the reinforcing bar into the reinforcing bar channel in the reinforcing bar traction and straightening machine. After the reinforcing bar is inserted into the through hole of the guide groove 12, the reinforcing bar is gently pushed forward in front of the guide groove 12, and the reinforcing bar can move into the reinforcing bar channel. This avoids the situation where the reinforcing bar is directly put into the reinforcing bar channel by the manual labor and is accidentally injured by the active traction wheel 21 and / or the driven traction wheel 23.

[0054] Furthermore, the outer circumferential surface of the driving traction wheel 21 and / or the driven traction wheel 23 is provided with an annular guide groove. The guide groove is provided on the radial outer circumferential surface of the driving traction wheel 21 and / or the driven traction wheel 23. The guide groove is formed by recessing from the surface of the driving traction wheel 21 and the driven traction wheel 23. The shape is not limited, but the guide groove is preferably arc-shaped.

[0055] Furthermore, the yaw shaft 22 is hinged to the frame 1 via a pin 43.

[0056] In detail, such as Figure 3 As shown, a mounting base 44 with through holes is installed on the rear plate 14 of the frame 1. The end of the yaw shaft 22 has a through hole. A pin 43 passes through the through holes of the mounting base 44 and the yaw shaft 22 to hinge the yaw shaft 22 to the mounting base 44. To prevent the pin 43 from disengaging from the mounting base 44 and the yaw shaft 22, and to ensure the reliability of the hinge between the yaw shaft 22 and the frame 1, limit bolts 45 are installed at both ends of the pin 43. Alternatively, the yaw shaft 22 and the frame 1 can also be hinged via a ball joint. Specifically, the ball joint includes a mating ball head and a ball seat. One of the ball head and the ball seat connects to the frame 1, and the other connects to the yaw shaft 22. In this way, the yaw shaft 22 can deflect relative to the frame 1. Of course, the yaw shaft 22 and the frame 1 can also be hinged via other methods besides a pin or a ball joint; there are no specific restrictions, as long as the yaw shaft can deflect relative to the frame.

[0057] Example 2

[0058] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0059] Compared to Embodiment 1, the reinforcing bar traction and straightening machine provided in this embodiment has the following structural design differences:

[0060] The difference mainly lies in the structure of the adjusting mechanism. The adjusting mechanism 4 of the embodiment includes a telescopic power source 46, a first connecting piece connected with the deflection shaft 22, a second connecting piece connected with the output end of the telescopic power source, and the first connecting piece and the second connecting piece are hingedly connected through a ball head and a ball bowl, so that the deflection shaft 22 can deflect relative to the output shaft of the telescopic power source 46, and the deflection movement of the deflection shaft 22 is smooth. In addition, other structures that can realize the deflection of the deflection shaft 22 relative to the output end of the telescopic power source 46 are also possible, and are not limited to being hingedly connected through a pin shaft or a ball joint.

[0061] Embodiment three

[0062] The same parts in the embodiment and the embodiment two are given the same reference numerals, and the same textual description is omitted.

In the embodiment, a feeding mechanism connecting the reinforcing bar cutting machine 5 and the header machine 6 is further included, and a controller is further included, which is in electrical connection with the driving mechanism 3, the telescopic power source 46, the reinforcing bar cutting machine 5, the header machine 6, and the feeding mechanism. The reinforcing bar 9 with a relatively long length is traction straightened by the reinforcing bar traction straightening machine, enters the reinforcing bar cutting machine 5, and is cut into a fixed length. Then, the reinforcing bars with a fixed length are transported one by one to the header machine 6 by the feeding mechanism, and the header operation of the reinforcing bar end is performed. The reinforcing bar cutting machine 5, the header machine 6, and the feeding mechanism are all prior art, and specific reference can be made to the patent CN214601655U, and the embodiment will not be described here.
