DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 4 The utility model provides a truss machine straightening and traction mechanism, comprising a base assembly 1, a mounting assembly 2 being provided on the base assembly 1, two straightening assemblies 3 being installed on the mounting assembly 2, and the two straightening assemblies 3 being symmetrically arranged, and an adjustment assembly 4 being installed between the two straightening assemblies 3;

[0025] Among them, the straightening assembly 3 includes a guide block 31, a fixed block 32, a side plate A 33, a side plate B 34, a fixed rod 35 and a pressure wheel 36. The fixed block 32 is installed on the installation assembly 2. A connecting rod is installed on the surface of the fixed block 32, and the connecting rod passes through and extends out of the surface of the fixed block 32. The side plate A 33 and the side plate B 34 are both installed on the connecting rod. A straightening hole is opened on the fixed block 32. The fixed rod 35 connects the side plate A 33 and the side plate B 34. The guide block 31 and the pressure wheel 36 are both installed between the side plate A 33 and the side plate B 34, and the pressure wheel 36 is arranged above the guide block 31.

[0026] Specifically, when straightening the steel bars, two straightening components 3 can be set on the installation component 2, and the two straightening components 3 are symmetrically arranged. At this time, the steel bars are passed through the guide block 31 and inserted into the straightening hole opened on the fixed block 32, and are brought into contact with the clamping wheel 36. The steel bars are moved by pulling the steel bars, so that the clamping wheel 36 set between the A side plate 33 and the B side plate 34 can generate downward pressure on the steel bars, thereby straightening the steel bars. When in use, the steel bars need to be inserted horizontally into the guide block 31 and the straightening hole. Therefore, when in use, a table needs to be set under the head and tail ends of the steel bars to avoid excessive downward movement of the steel bars during the clamping process of the clamping wheel 36, thereby causing the steel bars to bend in the opposite direction.

[0027] In this embodiment, the base assembly 1 includes a base 11 and a connecting plate 12. Both ends of the base 11 are hollowed out, and an insertion groove is opened at one end of the base 11. There are multiple connecting plates 12, and the multiple connecting plates 12 are all installed under the base 11.

[0028] Specifically, during use, in order to enable the entire device to be stably set up, a plurality of connecting plates 12 are arranged under the base 11, and connecting holes are provided on the connecting plates 12. The connecting plates 12 can be connected to the base through a bolt group, so that the entire device can be stably set up. In order to facilitate the installation of the installation component 2, the front and rear ends of the base 11 are hollowed out, and an insertion slot is opened at its right end to facilitate the installation of multiple installation components 2, straightening components 3, and adjustment components 4.

[0029] In this embodiment, the mounting assembly 2 includes a sliding block 21, a spring 22 and an extrusion plate 23. The sliding block 21 is arranged inside the base 11, the extrusion plate 23 is slidably arranged on the sliding block 21, and the spring 22 connects the sliding block 21 and the extrusion plate 23 respectively.

[0030] Specifically, during use, in order to enable the installation component 2 to be controllably connected to the base 11, thereby facilitating the removal or placement of the installation component 2, the sliding block 21 can be slid into the base 11 through the insertion slot. Since an extrusion plate 23 is slidably provided on the sliding block 21, and a spring 22 connects the sliding block 21 and the extrusion plate 23, when the sliding block 21 and the extrusion plate 23 are inserted into the base 11, the extrusion plate 23 can be pressed upwards to slide the sliding block 21 and the extrusion plate 23 in. After sliding to a suitable position, the extrusion plate 23 can be released. The extrusion plate 23 will press the inner wall of the base 11 downwards under the elastic force of the spring 22, so that the sliding block 21 and the extrusion plate 23 can be stably set inside the base 11.

[0031] In this embodiment, there are two sliding blocks 21, two springs 22 and two extrusion plates 23, and the two sliding blocks 21, two springs 22 and two extrusion plates 23 are symmetrically arranged; the mounting assembly 2 also includes a mounting plate 24, which is arranged above the base 11, and the two sliding blocks 21 are connected to the mounting plate 24.

[0032] Specifically, in order to enable the mounting plate 24 to be stably disposed on the base 11 , two sliding blocks 21 , two springs 22 , and two pressing plates 23 are provided, and the two are symmetrically disposed.

[0033] In this embodiment, the two fixing blocks 32 are both mounted on the mounting plate 24 .

[0034] Specifically, when in use, the two straightening components 3 are both installed on the mounting component 2, so that they can maintain their own stability during use, and in subsequent use, they can be connected or disconnected with the base component 1 along with the mounting component 2.

[0035] In this embodiment, the adjustment assembly 4 includes an A rotating member 41, a telescopic rod 42 and a B rotating member 43. The A rotating member 41 and the B rotating member 43 are respectively rotatably arranged between the two A side plates 33 and the B side plates 34, and the telescopic rod 42 is installed between the A rotating member 41 and the B rotating member 43.

[0036] Specifically, during use, in order to be able to adjust the angles of the two A side panels 33 and the B side panels 34 at the same time, and thus adjust the straightening angle, an adjustment component 4 can be set between the two straightening components 3, by respectively setting the A rotating member 41 and the B rotating member 43 between the two A side panels 33 and the B side panels 34, and setting the telescopic rod 42 between the A rotating member 41 and the B rotating member 43. At this time, by controlling the telescopic length of the telescopic rod 42, the straightening angles of the two straightening components 3 can be controlled.

[0037] The working principle and usage process of the present invention are as follows: when straightening the steel bar, the head end of the steel bar can be inserted into the guide block 31. After inserting the guide block 31, the clamping wheel 36 will perform preliminary straightening on it, and then insert it into the straightening hole, and insert it into another straightening hole, continue to pull the steel bar so that it contacts with the other clamping wheel 36, and perform secondary straightening on the steel bar through the clamping wheel 36, and then the straightened steel bar can be pulled out of the device from the other guide block 31, thereby completing the traction operation of the steel bar. When in use, the straightening angles of the two straightening components 3 can be adjusted by adjusting the component 4, so as to adapt to steel bars with different degrees of bending, and the two straightening components 3 are set on the mounting component 2, so that the two straightening components 3 can be stably set, thereby avoiding the phenomenon of the two straightening components 3 offsetting during the straightening and pulling of the steel bars.

[0038] The electronic components and modules used in the content of this utility model can be parts commonly used in the market that can realize the specific functions of this case, and the specific models and sizes can be selected and adjusted according to actual needs.
