Description

Technical Field

[0001] This utility model belongs to the field of truss production technology, specifically relating to a truss machine web member straightening device. Background Technology

[0002] A steel truss is a structural material made of steel bars, which are welded, cut into long sections, and then handed over for use. The cross-section of a steel truss is triangular, and the whole structure consists of an upper chord bar at the top corner and two lower chord bars at the two bottom corners. The two web bars are two wavy, curved web bars. The crests and troughs of the wavy web bars are welded to the upper and lower chord bars, respectively, thus forming a whole steel truss section.

[0003] In existing technologies, it is often necessary to straighten steel bars in truss production to facilitate processing and improve the connection performance between steel bars. Therefore, truss production lines need to be equipped with straightening mechanisms for truss steel bars. During the straightening process, straightening equipment generally straightens steel bars through the combined action of upper and lower straightening wheels. Steel bar straightening is divided into two categories: manual straightening and mechanical straightening. Manual straightening involves manually pulling the steel bars using straightening equipment, which results in high labor costs and unreliable accuracy.

[0004] Existing straightening devices typically apply the same straightening force to the surface of the reinforcing bars during the straightening process. If the straightening force is too large, it may make the initial straightening process more difficult; if the straightening force is too small, it may lead to a decrease in straightening accuracy. Therefore, we propose a straightening device for the web reinforcement of truss structures to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a truss machine web reinforcement straightening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A truss machine web reinforcement straightening device includes a support assembly, on which a B straightening assembly and two A straightening assemblies are mounted. An adjustment assembly is also mounted on the support assembly and is connected to the two A straightening assemblies.

[0008] The A straightening component includes a base plate, an A limiting plate, a B limiting plate, and a straightening member. The base plate is disposed on the support component. The A limiting plate and the B limiting plate are both disposed on the base plate and are perpendicular to each other. There are two A limiting plates and two B limiting plates, and the two A limiting plates and the two B limiting plates are symmetrically arranged. The straightening member is disposed on the base plate and is disposed between the two A limiting plates and the two B limiting plates.

[0009] The straightening component includes connecting rods, pressure rollers, and placement plates. Multiple placement plates are provided, and all placement plates are placed on a base plate. The multiple placement plates are evenly arranged, and the width of the multiple placement plates increases sequentially from left to right. Multiple connecting rods are provided, and the multiple connecting rods are respectively installed on the multiple placement plates. Multiple pressure rollers are provided, and the multiple pressure rollers are respectively rotatably mounted on the connecting rods.

[0010] Preferably, the A straightening assembly further includes an extrusion component, which includes a fixed rod, an extrusion roller, and a protruding block. The protruding block is installed on one side of the base plate, the fixed rod is installed on the protruding block, and the extrusion roller is rotatably mounted on the fixed rod, and the extrusion roller extrudes the A limiting plate inward.

[0011] Preferably, the A limiting plate and the B limiting plate are provided with an A connecting plate and a B connecting plate, and the A connecting plate and the B connecting plate are connected to the A limiting plate and the B limiting plate by a bolt group.

[0012] Preferably, the support assembly includes a base, an A support, and a B support, with the A support and the B support both mounted on the base, and the two A straightening assemblies respectively mounted on the A support and the B support.

[0013] Preferably, the support assembly further includes a C support, and the B straightening assembly is installed on the C support. The B straightening assembly has the same structure and size as the A straightening assembly.

[0014] Preferably, the adjusting assembly includes a moving block and a lead screw. Sliding grooves are provided on both the A support and the B support. Two moving blocks are provided, and the two moving blocks are respectively installed on the two base plates. The two moving blocks are slidably disposed in the two sliding grooves.

[0015] Preferably, the adjustment assembly further includes a motor, which is mounted on support B, and the output end of the motor is connected to the lead screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting two straightening components A and B on the support assembly, the reinforcing bars can be fully straightened, thus facilitating their processing. However, during straightening, to avoid excessive straightening force that makes it difficult to place the reinforcing bars between the two sets of clamping rollers in the initial stage, affecting straightening efficiency, and to avoid insufficient straightening force that leads to low straightening accuracy, the width of the multiple placement plates can be progressively increased from left to right. This allows the spacing between the multiple clamping rollers to increase progressively, resulting in a left-closed, right-sparse arrangement of the rollers. This achieves a step-by-step clamping effect on the reinforcing bars, thereby improving the aforementioned problems.

[0018] 2. By connecting the two A straightening components with the adjustment component, the spacing between the two A straightening components can be adjusted according to the length of different reinforcing bars during use. This allows for real-time adjustment of the spacing between the two A straightening components when straightening longer or shorter reinforcing bars. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-Figure 5 This utility model provides a truss machine web bar straightening device, including a support assembly 1, on which a B straightening assembly 3 and two A straightening assemblies 2 are installed. An adjustment assembly 4 is also installed on the support assembly 1, and the adjustment assembly 4 is connected to the two A straightening assemblies 2.

[0027] The straightening component 2 includes a base plate 21, an A limiting plate 23, a B limiting plate 24, and a straightening member 27. The base plate 21 is mounted on the support component 1. The A limiting plate 23 and the B limiting plate 24 are both mounted on the base plate 21 and are perpendicular to each other. There are two A limiting plates 23 and two B limiting plates 24, and the two A limiting plates 23 and the two B limiting plates 24 are symmetrically arranged. The straightening member 27 is mounted on the base plate 21 and is positioned between the two A limiting plates 23 and the two B limiting plates 24.

[0028] The straightening component 27 includes connecting rods 271, pressure rollers 272, and placement plates 273. Multiple placement plates 273 are provided, and all multiple placement plates 273 are provided on the base plate 21. The multiple placement plates 273 are evenly arranged, and the width of the multiple placement plates 273 increases sequentially from left to right. Multiple connecting rods 271 are provided, and the multiple connecting rods 271 are respectively installed on the multiple placement plates 273. Multiple pressure rollers 272 are provided, and the multiple pressure rollers 272 are respectively rotatably mounted on the connecting rods 271.

[0029] Specifically, when straightening reinforcing bars, the reinforcing bars can be inserted into the A straightening assembly 2 from right to left. At this time, the A limiting plate 23 and B limiting plate 24 set on the base plate 21 can clamp multiple placement plates 273, thereby ensuring the stable setting of the placement plates 273. In actual use, different straightening effects on the reinforcing bars can be achieved by adjusting the position and number of placement plates 273. Furthermore, multiple clamping rollers 272 are set and divided into two groups, arranged symmetrically, and the two groups of clamping rollers... Both 272 are set on the connecting rod 271. The reinforcing bar is placed between the two sets of clamping rollers 272. When the reinforcing bar passes through the two sets of clamping rollers 272, it can be straightened. During the straightening operation, four clamping rollers 272 are usually set near the front and three clamping rollers 272 are set near the rear. The density of the multiple clamping rollers 272 decreases from left to right. Therefore, it is easier for the reinforcing bar to enter between the two sets of clamping rollers 272 from the right side of the device during straightening. The straightening force increases as the reinforcing bar moves to the left, thus achieving precise straightening.

[0030] In this embodiment, the A straightening assembly 2 further includes an extrusion member 22, which includes a fixing rod 221, an extrusion roller 222, and a protruding block 223. The protruding block 223 is installed on one side of the base plate 21, the fixing rod 221 is installed on the protruding block 223, and the extrusion roller 222 is rotatably mounted on the fixing rod 221, and the extrusion roller 222 extrudes the A limiting plate 23 inward.

[0031] Specifically, when clamping multiple placement plates 273, in order to ensure that the A-limiting plate 23 located at the front can always move inward and thus squeeze the multiple placement plates 273, a protruding block 223 can be provided on the base plate 21, and a squeezing roller 222 can be provided on the protruding block 223. Since the squeezing roller 222 is eccentrically set with the fixed rod 221, when the squeezing roller 222 is rotated, it will squeeze the A-limiting plate 23, thereby allowing the A-limiting plate 23 to move inward, so that the placement plates 273 can be stably set. In use, the A-limiting plate 23 near the rear is fixedly set.

[0032] In this embodiment, A connecting plate 25 and B connecting plate 26 are provided on A limiting plate 23 and B limiting plate 24, and A connecting plate 25 and B connecting plate 26 are connected to A limiting plate 23 and B limiting plate 24 by bolt group.

[0033] Specifically, in order to ensure that the A limit plate 23 and the B limit plate 24 can be stably set and that their positions are relatively stable, an A connecting plate 25 and a B connecting plate 26 can be set above them. The A connecting plate 25 is connected to the A limit plate 23 and the B limit plate 24 by bolts, and then the B connecting plate 26 is connected to the A limit plate 23 and the B limit plate 24, thereby ensuring that the A limit plate 23 and the B limit plate 24 can be stably set.

[0034] In this embodiment, the support component 1 includes a base 11, an A support 12, and a B support 13. Both the A support 12 and the B support 13 are mounted on the base 11, and the two A straightening components 2 are respectively mounted on the A support 12 and the B support 13.

[0035] Specifically, during use, the two A straightening components 2 are installed on the A support 12 and the B support 13 respectively, so that the two A straightening components 2 can be set stably, and thus the steel bars can be set stably when straightening them in the subsequent process.

[0036] In this embodiment, the support component 1 also includes a C support 14, and the B straightening component 3 is installed on the C support 14. The B straightening component 3 and the A straightening component 2 have the same structure and size.

[0037] Specifically, in order to ensure that the B straightening component 3 can be set stably during use, the B straightening component 3 is installed on the C support 14. In order to fully straighten the steel bars during use, the B straightening component 3 can be set. The structure and size of the B straightening component 3 are the same as those of the A straightening component 2, and the B straightening component 3 and the A straightening component 2 are perpendicular to each other.

[0038] In this embodiment, the adjustment component 4 includes a moving block 41 and a lead screw 42. Sliding grooves are provided on both support A 12 and support B 13. There are two moving blocks 41, which are respectively installed on the two base plates 21 and slidably disposed in the two sliding grooves. The lead screw 42 is rotatably disposed on support A 12 and is threadedly connected to the two moving blocks 41. The adjustment component 4 also includes a motor 43, which is installed on support B 13 and the output end of the motor 43 is connected to the lead screw 42.

[0039] Specifically, in order to efficiently straighten steel bars of different lengths during actual use, movable blocks 41 are installed at the lower ends of both base plates 21, and the movable blocks 41 are slidably set in the sliding groove. The lead screw 42 is threadedly connected to the two movable blocks 41. During use, the output end of the motor 43 is connected to the lead screw 42, and the motor 43 is started to drive the lead screw 42 to rotate, thereby driving the movable blocks 41 to move. The two movable blocks 41 are symmetrically arranged, so that the distance between the two movable blocks 41 can be adjusted when the lead screw 42 is rotated, thereby adjusting the distance between the two A straightening components 2.

[0040] The working principle and usage process of this utility model are as follows: When straightening steel bars, the steel bars can be inserted into straightening component A 2 from right to left. At this time, the steel bars can be passed through straightening component A 2, straightening component B 3, and straightening component A 2 in sequence to achieve relatively accurate straightening. In use, the two straightening components A 2 and straightening component B 3 can straighten the steel bars step by step, making the straightening operation more efficient and accurate. When straightening steel bars of different lengths, the spacing between the two straightening components A 2 can be adjusted by adjusting component 4, so that steel bars of different lengths can be straightened.

[0041] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
