Description

Technical Field

[0001] This utility model relates to the field of steel strip extrusion technology, specifically a guiding device for a steel strip flattening machine. Background Technology

[0002] Steel strip is a strip of steel made from carbon steel. Its main uses are as a core component for traction and transport in belt conveyors and for securing goods. It is a narrow, long steel plate specially produced by various steel rolling mills to meet the needs of industrialized production of metal products and machinery in different sectors. Currently, with the continued promotion of ferrous products, in actual production processes, steel strips are usually flattened using flattening devices to meet subsequent processing or usage requirements.

[0003] Existing steel strip flattening devices are generally equipped with a flattening mechanism, the core component of which is two extrusion rollers. During operation, the steel strip is conveyed between the two rollers and flattened by extrusion. However, during long-term use, because the steel strip always enters the extrusion rollers along a fixed path, only local areas of the extrusion rollers will wear. At this time, the rest of the extrusion rollers remain intact, but the entire roller needs to be replaced, resulting in unnecessary waste of resources.

[0004] Therefore, such as Figure 5 As shown, existing technologies typically add a guide mechanism in front of the flattening mechanism. This guide mechanism includes a mounting shaft 25 fixedly mounted on the steel strip flattening body and two guide rings 26 sleeved on the mounting shaft 25. Each guide ring 26 is coaxially fixedly connected to a fixing ring 27 also sleeved on the mounting shaft 25. The fixing rings 27 are bolted to maintain their relative position with the mounting shaft 25. During operation, by adjusting the position of the guide rings 26 on the mounting shaft 25, the steel strip 5 can be pre-guided before entering the flattening mechanism, thereby changing the conveying position of the steel strip 5 upon entering the flattening mechanism and alleviating the problem of localized wear on the extrusion rollers.

[0005] However, during the adjustment and fixing process of this guiding mechanism, the gap between the two guide rings is prone to being too large or too small, making it difficult to accurately match the actual size of the steel strip and affecting the guiding effect. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a guiding device for a steel strip flattening machine. When the two pads are moved and adjusted, the distance between them remains constant, preventing any difficulty in accurately matching the actual size of the steel strip and improving the guiding effect.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a guide device for a steel strip flattening machine, including a support plate fixedly installed on the body of the steel strip flattening machine, two pads slidably installed on the support plate, and a locking mechanism that can lock the position of the pads is provided on the pads. Rollers are rotatably installed on the pads, and a channel for the steel strip to pass through is formed between the two rollers. The two pads are detachably connected by a synchronous connecting rod, and during the sliding of one pad, the other pad is driven to slide synchronously through the synchronous connecting rod.

[0008] As a further optimization of the guiding device for a steel strip flattening machine, the support plate is provided with a receiving slot and the bottom of the support plate is provided with an inclined surface. The pad is fixedly connected to the mounting plate, and the mounting plate is slidably mounted on the support plate. The locking mechanism includes a connecting plate, an L-shaped transmission rod and a driving assembly. The connecting plate is located in the receiving slot. One end of the L-shaped transmission rod is rotatably mounted on the connecting plate, and the other end of the L-shaped transmission rod is fixedly provided with a friction block. Both the friction block and the inclined surface are provided with friction layers. During the process of the driving assembly driving the L-shaped transmission rod to rotate, the friction layers of the friction block and the friction layers of the inclined surface can contact and rub against each other.

[0009] As a further optimization of the guiding device for a steel strip flattening machine, the L-shaped transmission rod is rotatably connected to a lever at one end, and the driving assembly includes a turntable and a screw. One end of the screw is fixedly connected to the turntable, and the other end of the screw passes through the mounting plate and is threadedly connected to the mounting plate. When the turntable is rotated and the screw moves downward, the screw pushes the lever to rotate so that the L-shaped transmission rod rotates.

[0010] As a further optimization of the guiding device for a steel strip flattening machine, the surface of the screw that contacts the lever is provided with an arc-shaped surface.

[0011] As a further optimization of the guide device for a steel strip flattening machine, the mounting plate is fixedly connected to an extension block, the extension block has a through hole, an indicator rod is slidably inserted in the through hole, and an extension plate is fixedly connected to one end of the L-shaped transmission rod near the friction block. The extension plate extends to the bottom of the indicator rod, and the L-shaped transmission rod can drive the extension plate to rotate during rotation to lift the indicator rod.

[0012] As a further optimization of the guide device for a steel strip flattening machine, the two ends of the indicator rod extending out of the through hole are respectively fixedly provided with an indicator block and an anti-detachment block, and the distance between the indicator block and the anti-detachment block is greater than the thickness of the extension block.

[0013] As a further optimization of the guiding device for a steel strip flattening machine, the two ends of the synchronous connecting rod are respectively inserted into the pad.

[0014] As a further optimization of the guide device for a steel strip flattening machine, the two ends of the synchronous connecting rod are fixedly connected with insert plates, and the insert plates are L-shaped. The side of the pad is fixedly provided with a ring, and one end of the insert plate is inserted into the ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a support plate fixed to the body of a steel strip flattening machine. Two pads are slidably mounted on the support plate. During the position adjustment of the two pads, due to the presence of a synchronous connecting rod, the movement of one pad is accompanied by the movement of the other pad. In this way, the distance between the two pads only needs to be adjusted before initial use, and the distance between them remains fixed during subsequent adjustments. This avoids the problem of inaccurate matching with the actual size of the steel strip, thus improving the guiding effect. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.

[0024] Example 1

[0025] A guiding device for a steel strip flattening machine, such as Figure 1 and Figure 2 As shown, the device includes a support plate 1 fixedly mounted on the body of the steel strip 5 flattening machine. Two pads 3 are slidably mounted on the support plate 1, and the pads 3 are equipped with a locking mechanism that can lock the position of the pads 3. Rollers 4 are rotatably mounted on the pads 3, and a channel for the steel strip 5 to pass through is formed between the two rollers 4. The two pads 3 are detachably connected by a synchronous connecting rod 22. During the sliding process of one pad 3, the other pad 3 is driven to slide synchronously through the synchronous connecting rod 22.

[0026] The position between the two rollers 4 is pre-reserved according to the size of the steel strip 5, and then the pads 3 are connected by the synchronous connecting rod 22. When the extrusion roller of the steel strip 5 flattening machine is damaged, the locking mechanism can be adjusted to make the pads 3 in the unlocked position, and then one of the pads 3 can be slid. Under the action of the synchronous connecting rod 22, the other pad 3 will slide to the appropriate position. After the position is adjusted, the synchronous connecting rod 22 can be disassembled without affecting the subsequent passage of the steel strip 5. After reaching the appropriate position, the locking mechanism is adjusted to make the pads 3 in the locked state. At this time, the positions of the two pads 3 are locked, and the two rollers 4 can guide the steel strip 5.

[0027] During the position adjustment process of the two pads 3 of this utility model, due to the existence of the synchronous connecting rod 22, when one of the two pads 3 moves, the other pad 3 can also move accordingly. In this way, the two pads 3 only need to be adjusted before initial use, and the distance between the two pads 3 will always be fixed when moving and adjusting the two pads 3 in the future. There will be no situation where it is difficult to accurately match the actual size of the steel strip 5, thus improving the guiding effect.

[0028] Furthermore, if one of the pads 3 is damaged, the corresponding damaged pad 3 can be directly removed and replaced without removing both pads 3 and their associated structures at the same time, making it easy to repair.

[0029] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0030] Example 2

[0031] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 , Figure 3 and Figure 4As shown, the support plate 1 has a receiving groove 2, and the bottom of the support plate 1 has an inclined surface 20. The pad 3 is fixedly connected to the mounting plate 6, and the mounting plate 6 is slidably disposed on the support plate 1. The locking mechanism includes a connecting plate 11, an L-shaped transmission rod 17, and a driving assembly. The connecting plate 11 is located in the receiving groove 2. One end of the L-shaped transmission rod 17 is rotatably disposed on the connecting plate 11. Specifically, a rotating shaft 15 is fixedly disposed on the connecting plate 11. The rotating shaft 15 rotates through one end of the L-shaped transmission rod 17. A friction block 18 is fixedly disposed on the other end of the L-shaped transmission rod 17. Both the friction block 18 and the inclined surface 20 are provided with friction layers 12. During the process of the driving assembly driving the L-shaped transmission rod 17 to rotate, the friction layers 12 of the friction block 18 and the friction layers 12 of the inclined surface 20 can contact and rub against each other.

[0032] When the locking mechanism needs to be adjusted to put the pad 3 in the locked position, the drive assembly drives the L-shaped transmission rod 17 to rotate, causing the end of the L-shaped transmission rod 17 with the friction block 18 to rotate accordingly, until the friction layer 12 on the surface of the friction block 18 contacts and rubs against the friction layer 12 on the inclined surface 20 of the support plate 1. Conversely, when the locking mechanism needs to be adjusted to put the pad 3 in the unlocked position, the drive assembly no longer drives the L-shaped transmission rod 17 to rotate. At this time, the friction layer 12 of the friction block 18 of the L-shaped transmission rod 17 no longer contacts the friction layer 12 on the inclined surface 20. The material of the friction layer 12 is conventional prior art in this field and will not be described in detail here. For example, sintered friction materials or semi-metallic friction materials can be used.

[0033] Example 3

[0034] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 and Figure 4 As shown, one end of the L-shaped transmission rod 17, which is rotatably connected to the connecting plate 11, is fixedly connected to a lever 16. The drive assembly includes a turntable 7 and a screw 13. One end of the screw 13 is fixedly connected to the turntable 7, and the other end of the screw 13 passes through the mounting plate 6 and is threadedly connected to the mounting plate 6. When the turntable 7 is rotated, causing the screw 13 to move downward, the screw 13 pushes the lever 16 to rotate, thereby causing the L-shaped transmission rod 17 to rotate.

[0035] The operator rotates turntable 7, which in turn drives screw 13 to rotate. During rotation, screw 13 moves downward and pushes lever 16 to rotate. Since lever 16 and L-shaped transmission rod 17 are fixedly connected, L-shaped transmission rod 17 will rotate with lever 16 until the friction layer 12 on the surface of friction block 18 contacts and rubs against the friction layer 12 on the inclined surface 20 of support plate 1. When it is necessary to release the locking of pad 3, turntable 7 is rotated in the opposite direction. Screw 13 will move upward away from lever 16 during rotation. At this time, friction block 18 on L-shaped transmission rod 17 will leave the inclined surface 20 under the action of gravity and will no longer contact the friction layer 12 on the inclined surface 20. The surface of screw 13 in contact with lever 16 is provided with arc-shaped surface 14 to reduce damage to the contact surface of screw 13 and lever 16.

[0036] Example 4

[0037] This embodiment is an improvement on embodiment 2. Its main structure is the same as embodiment 2, but the improvement lies in that: an extension block 8 is fixedly connected to the mounting plate 6, and a through hole is provided on the extension block 8. An indicator rod 10 slides through the through hole. Figure 3 and Figure 4 As shown, an extension plate 19 is fixedly connected to one end of the L-shaped transmission rod 17 near the friction block 18. The extension plate 19 extends to the bottom of the indicator rod 10. During the rotation of the L-shaped transmission rod 17, it can drive the extension plate 19 to rotate so as to lift the indicator rod 10.

[0038] To facilitate operators in knowing whether the pad 3 is in a locked state, an indicator rod 10 is provided in this embodiment. When the pad 3 is in a locked state, the extension plate 19 moves upward as a whole after a certain deflection. During this process, the extension plate 19 will push the indicator rod 10 upward out of the through hole. At this time, the operator can determine that the pad 3 is in a locked state.

[0039] To prevent the indicator rod 10 from dislodging from the through hole, an indicator block 9 and an anti-dislodgement block 21 are fixedly installed at both ends of the indicator rod 10 extending out of the through hole, respectively, and the distance between the indicator block 9 and the anti-dislodgement block 21 is greater than the thickness of the extension block 8. The greater distance between the indicator block 9 and the anti-dislodgement block 21 than the thickness of the extension block 8 allows the indicator rod 10 a certain range of motion.

[0040] Example 5

[0041] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2As shown, both ends of the synchronizing rod 22 are respectively inserted into the pad 3. In order to facilitate the connection between the synchronizing rod 22 and the pad 3, the two ends of the synchronizing rod 22 are fixedly connected with insert plates 23, and the insert plates 23 are set in an L shape. The side of the pad 3 is fixedly provided with a retaining ring 24, and one end of the insert plate 23 is inserted into the retaining ring 24.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
