Description

Technical fields:

[0001] This utility model relates to the technical field of rebar drawing wire processing equipment, and more specifically to a support and placement frame for rebar drawing wire. Background technology:

[0002] The existing method of drawing steel bars involves cold drawing the steel bars to lengthen and thin them, and then winding them into coils. Generally, the diameter of the steel wires in the coils is relatively large at this stage. Therefore, it is necessary to place them in the corresponding drawing equipment for secondary drawing to gradually lengthen them and reduce their outer diameter to meet the processing requirements.

[0003] During the subsequent pulling process, the coiled steel wire needs to be placed on the support feeding frame. As it is continuously pulled out, the wire is fed out by the rotation of the support components of the support feeding frame. However, the existing support feeding frame has its base and upper support frame welded together. During use, some support rods of the upper support frame may deform or bend during the support process, requiring replacement or correction. Since it is connected to the base, it cannot be corrected or repaired at the top, so it can only be replaced, which requires replacing the base as well, increasing the replacement cost.

[0004] Secondly, existing support feeding racks generally do not have a wire guide structure for laying out reinforcing bars, requiring additional guide structures to be installed around the support feeding rack, which is not ideal. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support and placement frame for rebar wire drawing. Its lower placement base, horizontal support frame and central support frame can be separated. When any one of them needs to be replaced, the other part does not need to be replaced, reducing replacement costs. Moreover, it has its own upper and lower rollers to guide the rebar wire output without additional installation, and the use effect is good.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A support frame for reinforcing bar wire includes a lower base, a horizontal fixing plate fixed to the center of the top surface of the lower base, a connecting seat fixed to the center of the top surface of the horizontal fixing plate, and the lower part of a vertical central shaft movably connected to the connecting seat via a bearing, with the upper part of the vertical central shaft extending out of the top surface of the connecting seat.

[0008] Above the connecting seat is a horizontally extending horizontal support frame. A central support frame extending upward is fixed in the middle of the top surface of the horizontal support frame for fitting onto the steel wire drawing coil. An upper horizontal fixing plate is fixed in the middle bottom surface of the horizontal support frame. A central vertical sleeve is fixed in the middle of the top surface of the upper horizontal fixing plate. The upper part of the vertical central shaft is inserted into the central through hole of the upper horizontal fixing plate and the central vertical through hole of the central vertical sleeve. The top of the vertical central shaft reaches the middle of the central vertical sleeve.

[0009] Multiple hemispherical support parts are fixed on the top surface of the connecting seat, and the upper horizontal fixing plate presses against the spherical surface at the bottom of all the hemispherical support parts.

[0010] The horizontal support frame includes an outer ring and an inner ring. The inner ring is inserted into the outer ring. One end of a plurality of transverse connecting rods is welded and fixed to the outer side wall of the inner ring. The other end of all transverse connecting rods is welded and fixed to the inner side wall of the outer ring. The central axes of the inner and outer rings coincide. All transverse connecting rods are evenly distributed between the outer and inner rings with the central axis of the inner ring as the center.

[0011] The central support frame includes a first connecting rod extending forward and backward and a second connecting rod extending left and right. The top surface of the middle part of the first connecting rod presses against the top surface of the middle part of the second connecting rod and is welded and fixed. The front and rear ends of the first connecting rod are formed with first inclined support rods extending downward and outward. The bottom end of the first inclined support rod is welded and fixed to the top surface of the inner ring. The left and right ends of the second connecting rod are formed with second inclined support rods extending downward and outward. The bottom end of the second inclined support rod is welded and fixed to the top surface of the inner ring.

[0012] Multiple horizontally extending connecting rods are welded and fixed to one end on the inner wall of the first and second inclined support rods, and the other end of the connecting rods is welded and fixed to the outer wall of the central vertical sleeve.

[0013] A main vertical support beam is fixed to the top surface of one side of the lower base. A vertical lifting adjustment mechanism is fixed to the middle of the front wall of the main vertical support beam. A vertical fixing plate is fixed to the front wall of the lifting block of the vertical lifting adjustment mechanism. A horizontal fixing plate is fixed to the top and bottom surfaces of the vertical fixing plate. The upper roller support frame is located below the upper horizontal fixing plate. The upper roller is movably connected to the upper roller support frame through bearings. The lower roller is movably connected to the lower roller support frame through bearings. The upper roller is located directly above the lower roller, and the two cooperate with each other.

[0014] The outstanding effect of this utility model is:

[0015] Its lower base and horizontal support frame, as well as the components on them, can be disassembled. If one part needs to be replaced, the other part does not need to be replaced, reducing replacement costs. Moreover, its built-in upper and lower rollers can guide the output of steel wire without the need for additional installation, resulting in good performance. Attached image description:

[0020] For example, see below. Figures 1 to 3 As shown, a support frame for reinforcing bar wire includes a lower base 10, a horizontal fixing plate 11 fixed in the middle of the top surface of the lower base 10, a connecting seat 12 fixed in the middle of the top surface of the horizontal fixing plate 11, the lower part of the vertical central shaft 13 being movably connected to the connecting seat 12 via a bearing, and the upper part of the vertical central shaft 13 extending out of the top surface of the connecting seat 12.

[0021] Above the connecting seat 12, a horizontally extending horizontal support frame 20 is provided. A centrally extending support frame 30 for fitting onto the steel wire drawing coil is fixed to the center of the top surface of the horizontal support frame 20. An upper horizontal fixing plate 21 is fixed to the bottom center of the horizontal support frame 20. A central vertical sleeve 22 is fixed to the center of the top surface of the upper horizontal fixing plate 21. The upper part of the vertical central shaft 13 is inserted into the central through hole of the upper horizontal fixing plate 21 and the central vertical through hole of the central vertical sleeve 22. The top end of the vertical central shaft 13 reaches the center of the central vertical sleeve 22. Because the top end of the vertical central shaft 13 reaches the center of the central vertical sleeve 22, the vertical central shaft 13 is less likely to slip out of the central vertical sleeve 22, ensuring a secure connection between the two.

[0022] Multiple hemispherical support parts 121 are fixed on the top surface of the connecting seat 12, and the upper horizontal fixing plate 21 presses against the spherical surface at the bottom of all the hemispherical support parts 121.

[0023] The horizontal support frame 20 includes an outer ring body 23 and an inner ring body 24. An upper horizontal fixing plate 21 is fixed on the bottom surface of the inner ring body 24. The inner ring body 24 is inserted into the outer ring body 23. One end of a plurality of transverse connecting rods 25 is welded and fixed on the outer side wall of the inner ring body 24. The other end of all transverse connecting rods 25 is welded and fixed on the inner side wall of the outer ring body 23. The central axes of the inner ring body 24 and the outer ring body 23 coincide. All transverse connecting rods 25 are evenly distributed between the outer ring body 23 and the inner ring body 24 with the central axis of the inner ring body 24 as the center.

[0024] Furthermore, the central support frame 30 includes a first connecting rod 31 extending forward and backward and a second connecting rod 32 extending left and right. The top surface of the middle part of the first connecting rod 31 presses against the top surface of the middle part of the second connecting rod 32 and is welded and fixed. The front and rear ends of the first connecting rod 31 are formed with a first inclined support rod part 311 extending downward and outward.

[0025] Multiple horizontally extending connecting rods 1 are welded and fixed to the inner wall of the first inclined support rod portion 311 and the inner wall of the second inclined support rod portion 321. The other end of the connecting rod 1 is welded and fixed to the outer wall of the central vertical sleeve 22.

[0026] A self-lubricating cover 2 is fitted at the top of the vertical central shaft 13, and the outer wall of the self-lubricating cover 2 is in close contact with or near the inner wall of the central vertical sleeve 22. In this embodiment, the self-lubricating cover 2 is made of polytetrafluoroethylene.

[0027] Furthermore, a main vertical support beam 40 is fixed to the top surface of one side of the lower base 10. A vertical lifting adjustment mechanism is fixed to the middle of the front wall of the main vertical support beam 40. A vertical fixing plate 51 is fixed to the front wall of the lifting block 50 of the vertical lifting adjustment mechanism. A horizontal fixing plate 52 is fixed to both the top and bottom surfaces of the vertical fixing plate 51. The upper roller support frame 53 is located below the upper horizontal fixing plate 52. An upper roller 54 is movably connected to the upper roller support frame 53 via bearings. A lower roller 56 is movably connected to the lower roller support frame 55 via bearings. The upper roller 54 is located directly above the lower roller 56, and the two cooperate with each other.

[0028] The top surface of the top plate of the upper roller support frame 53 is fixed with a plurality of upper vertical screws 531. The top of the upper vertical screws 531 extends out of the top surface of the corresponding through hole of the upper horizontal fixing plate 52 and is screwed with an upper adjusting nut 532. The bottom surface of the upper adjusting nut 532 presses against the top surface of the upper horizontal fixing plate 52. The first spring 533 is inserted into the upper vertical screws 531, with its top end bearing on the top surface of the upper horizontal fixing plate 52 and its lower end bearing on the top surface of the top plate of the upper roller support frame 53.

[0029] Multiple lower vertical screws 551 are fixed to the bottom surface of the base plate of the lower roller support frame 55. The bottom end of the lower vertical screw 551 extends out of the bottom surface of the corresponding through hole of the lower horizontal fixing plate 52 and is screwed with a lower adjusting nut 552. The top surface of the lower adjusting nut 552 presses against the bottom surface of the lower horizontal fixing plate 52. The second spring 553 is inserted into the lower vertical screw 551, with its top end bearing on the bottom surface of the base plate of the lower roller support frame 55 and its lower end bearing on the top surface of the lower horizontal fixing plate 52.

[0030] The vertical lifting adjustment mechanism includes an upper connecting plate and a lower connecting plate fixed to the middle of the front wall of the main vertical support beam 40. A vertical adjusting screw 41 is movably connected to the upper and lower connecting plates via bearings. The bottom end of the vertical adjusting screw 41 extends out of the lower connecting plate and is fixed with a rotating wheel. A lifting block 50 is screwed onto the vertical adjusting screw 41. A vertical guide rail 42 is fixed to the front wall of the main vertical support beam 40 behind the vertical adjusting screw 41. A vertical guide groove is formed in the middle of the front wall of the vertical guide rail 42. The rear part of the lifting block 50 is located in the vertical guide groove, with its left and right side walls tightly against the inner side walls of the vertical guide groove, and its rear wall tightly against the rear wall of the vertical guide groove. The height of the lifting block 50 can be adjusted by rotating the rotating wheel, making the adjustment convenient.

[0031] Both the upper roller 54 and the lower roller 56 have corresponding annular grooves formed in their middle portions. These annular grooves can limit the movement of the conveyed reinforcing steel wire.

[0032] In this embodiment, the coiled steel wire can be looped onto the central support frame 30 and pressed against the horizontal support frame 20. Then, one end of the steel wire is output forward along the upper roller 54 and the lower roller 56. The upper roller 54 and the lower roller 56 act as guides, and the elastic pressing action of the first spring 533 and the second spring 553 makes the upper roller 54 and the lower roller 56 press and guide the steel wire to a certain extent, preventing it from moving out from between the upper roller 54 and the lower roller 56.

[0033] like Figure 4As shown in this embodiment, in order to further improve the guiding and limiting effect, a self-lubricating limiting plate 5 is fixed on the inner side wall of the vertical fixing plate 51, a front baffle is fixed between the front ends of the two horizontal fixing plates 52, and a second self-lubricating limiting plate 6 is fixed on the rear wall of the front baffle. This allows the reinforcing wire to be limited in front and back by the self-lubricating limiting plate 5 and the second self-lubricating limiting plate 6 when it is being conveyed between the upper roller 54 and the lower roller 56, preventing it from moving out of the middle.

[0034] When in use, if the lower base 10, horizontal support frame 20 and central support frame 30 are damaged and cannot be repaired and need to be replaced, you only need to disassemble the horizontal support frame 20 (the horizontal support frame 20 and the central support frame 30 are fixedly connected) to replace the lower base 10 or replace the entire horizontal support frame 20 and central support frame 30. It does not require replacing all the parts together, so the replacement is convenient and the replacement cost is low.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
