Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of strip steel raw material feeding technology, and more specifically, to a combined unit for the production of light steel keel. Background Technology

[0002] A combined production line for light steel keel is a type of equipment used to produce light steel keels. It typically consists of a feeding machine, a forming machine, and a cutting machine. The feeding machine is used to hold the strip steel raw materials required for light steel keel production. The forming machine is the core part of the combined production line. It continuously cold rolls the strip steel through a series of rollers to process the strip steel into light steel keels with specific shapes and sizes. The cutting machine can cut the light steel keels to a preset length to ensure that the produced light steel keels have uniform specifications and dimensions.

[0003] However, during the feeding process of the grating machine, the strip steel material is usually wound around a strip steel coil. The strip steel coil and the grating machine are generally installed using an expansion sleeve. The installation method is that the main shaft of the grating machine is usually designed with a part for installing the expansion sleeve. After the strip steel coil is fitted onto the main shaft, the bolts on the expansion sleeve are tightened, which generates friction between the inner ring of the expansion sleeve and the main shaft. At the same time, the outer ring of the expansion sleeve expands outward, tightly supporting the inner hole of the strip steel coil, thereby achieving a tight connection between the strip steel coil and the main shaft of the grating machine.

[0004] However, the expansion sleeve mainly connects the strip coil to the spindle through radial expansion force, and its ability to withstand axial force is relatively limited. When the strip is subjected to large axial tensile or impact forces during the unloading process, it is easy for the strip coil to shift in the axial direction, affecting the stability and accuracy of unloading.

[0042] 2. In this disclosure, by setting up an auxiliary positioning mechanism, an electric wrench can be used to turn the first bolt head, thereby causing the threaded rod to rotate.

At this time, during the positioning process of the positioning block positioning the steel coil sleeve, the clamping block and the positioning plate can cooperate to achieve auxiliary positioning of the steel coil sleeve, thereby avoiding its position displacement due to external force.

[0043] 3. In this disclosure, by setting up a rotating mechanism, the operation of the first motor can drive the second pulley to rotate, and then drive the first pulley and the support column to rotate through the transmission of the belt, thereby facilitating the feeding of the strip steel raw material through the support shell and the strip steel coil sleeve;

[0044] 4. In this disclosure, by setting up the first brake disc, the second brake disc and the electric push rod, in the event of a mechanical failure, the operation of the electric push rod can drive the second brake disc to press against the surface of the first brake disc, thereby facilitating emergency braking of the support column by means of the friction between the first brake disc and the second brake disc;

[0045] 5.

[0058] like Figures 1-4 The diagram illustrates a combined unit for producing light steel keel according to an embodiment of this disclosure. It includes a feeding machine, a forming machine, and a cutting machine. The forming machine and cutting machine are located on one side of the feeding machine. The feeding machine is used to hold the strip steel raw material 7 required for light steel keel production. The forming machine continuously cold rolls the strip steel through a series of rollers, processing it into light steel keels with specific shapes and sizes. The cutting machine cuts the light steel keel to a preset length, ensuring that the produced light steel keels have uniform specifications and dimensions. Thus, the strip steel raw material 7, after feeding, forming, and cutting, forms qualified light steel keels. The feeding machine includes a base 1, a support seat 2, a support column 3, a support shell 4, a strip steel coil 6, a positioning mechanism, and a rotating mechanism. The support base 2 is fixedly mounted on the base 1. The support base 2 has a support opening. The support column 3 is rotatably mounted in the support opening. The support shell 4 is cylindrical and is fixedly mounted on the support column 3. The side wall of the support shell 4 is fixedly mounted with a positioning plate 5.

The positioning mechanism is mounted on the support shell 4 for positioning between the support shell 4 and the strip steel coil 6. The rotating mechanism is mounted between the support column 3 and the support base 2 for driving the support column 3 to rotate. It should be noted that the forming machine and the cutting machine are not the focus of this embodiment. Existing equipment can be used, so they are not shown in the drawings. The forming machine model can be SZ-90, and the cutting machine model can be SKJ400.

[0059] Reference Figure 1 and Figure 2The rotating mechanism includes a fixed groove 8, a first pulley 9, a fixed frame 10, and a first motor 12. The fixed groove 8 is opened on the top side wall of the support base 2 and is connected to the support opening. The first pulley 9 is fixedly mounted on the support column 3. The fixed frame 10 is fixedly mounted on the top side wall of the support base 2. A second pulley is rotatably mounted on the fixed frame 10. A belt is provided for transmission between the first pulley 9 and the second pulley. The first motor 12 is mounted on the fixed frame 10. The output end of the first motor 12 is fixedly connected to the second pulley. Specifically, the operation of the first motor 12 can drive the second pulley to rotate, and then drive the first pulley 9 and the support column 3 to rotate through the transmission of the belt, thereby facilitating the feeding of the strip steel raw material 7 through the support housing 4 and the strip steel coil sleeve 6.

[0060] Reference Figure 3 and Figure 4The positioning mechanism includes a positioning port 13, a positioning seat 14, a positioning block 15, a moving mechanism, and an auxiliary positioning mechanism. Multiple positioning ports 13 are equidistantly spaced on the side wall of the support housing 4. The positioning seat 14 is slidably disposed within the support housing 4. A positioning groove is formed on the side wall of the positioning seat 14 on one side of the positioning port 13, with the positioning port 13 aligned with the positioning groove. The positioning block 15 is slidably disposed within the positioning groove. The moving mechanism is mounted on the positioning seat 14 to drive the multiple positioning blocks 15 to move synchronously. The auxiliary positioning mechanism is mounted on the positioning seat 14 to assist in positioning. The disc 5 is positioned with the strip coil 6. The moving mechanism includes an adjusting block 16, an adjusting rod 17, a bidirectional screw 18, and a synchronous rotation mechanism. Two adjusting blocks 16 are slidably arranged at the bottom of the positioning groove. An adjusting rod 17 is hinged between the adjusting blocks 16 and adjacent adjusting blocks 16. The bidirectional screw 18 is rotatably arranged in the positioning groove and passes through two adjacent adjusting blocks 16 through a threaded connection. The synchronous rotation mechanism is arranged in the positioning seat 14 and is used to drive multiple bidirectional screws 18 to rotate synchronously. The synchronous rotation mechanism includes a first cavity, A first gear 19, a first gear ring 20, and a drive mechanism are provided. A positioning seat 14 has an annular first cavity on one side of multiple positioning slots. The first gear 19 is rotatably mounted within the first cavity on one side of the bidirectional screw 18. The first gear 19 is fixedly connected to the adjacent bidirectional screw 18. The first gear ring 20 is rotatably mounted within the first cavity and meshes with the first gear 19. A drive mechanism is mounted on the positioning seat 14 to drive the first gear ring 20 to rotate. The drive mechanism includes a second gear 21, a drive port, a drive prism 22, and... The first bolt head 23 and the second gear 21 are rotatably disposed in the first cavity. The second gear 21 meshes with the first gear ring 20. The drive port is opened on the side wall of the first cavity and passes through the positioning seat 14. The drive prism 22 is rotatably disposed in the support housing 4 and passes through the drive port. The drive prism 22 passes through the second gear 21 and is slidably connected with the second gear 21. The first bolt head 23 is rotatably disposed on the support housing 4 and is fixedly connected to the drive prism 22. An anti-slip pad is fixedly disposed on the positioning block 15.

[0061] Specifically, the operator can use an electric wrench to tighten the first bolt head 23, thereby causing the drive prism 22 to rotate. Simultaneously, the sliding engagement of the drive prism 22 with the second gear 21 drives the second gear 21 to rotate. Furthermore, the meshing of the first gear ring 20 with the second gear 21 and the meshing of the first gear ring 20 with the first gear 19 drives the first gear 19 and the double-acting screw 18 to rotate. Thus, the threaded engagement of the double-acting screw 18 with the adjusting block 16 causes the two adjusting blocks 16 in the same positioning groove to move relative to each other. The adjusting rod 17 pushes the positioning block 15 to move, thereby pressing the positioning block 15 against the surface of the strip sleeve 6. The friction between the positioning block 15 and the inner wall of the strip sleeve 6 achieves the positioning between the strip sleeve 6 and the support housing 4.

[0062] Reference Figure 3 and Figure 4 The auxiliary positioning mechanism includes a clamping block 24, a threaded rod 25, and a second bolt head 26. The clamping block 24 is fixedly installed at the end of the positioning block 15 away from the positioning disk 5. The threaded rod 25 is rotatably installed inside the support housing 4 and passes through the positioning seat 14 through a threaded engagement. The second bolt head 26 is rotatably installed on the side wall of the support housing 4 and is fixedly connected to the threaded rod 25. Specifically, the operator can use an electric wrench to tighten the first bolt head 23, thereby causing the threaded rod 25 to rotate. At the same time, the threaded engagement between the threaded rod 25 and the positioning seat 14 drives the positioning block 15 and the clamping block 24 to move, making the clamping block 24 aligned with the side wall of the steel coil sleeve 6. At this time, during the positioning process of the positioning block 15 positioning the steel coil sleeve 6, the clamping block 24 and the positioning disk 5 can cooperate to achieve auxiliary positioning of the steel coil sleeve 6, thereby avoiding its position displacement due to external forces.

[0063] Reference Figure 2 It also includes an L-shaped brake frame 27, which is fixedly mounted on the support base 2. A first brake disc 28 is fixedly mounted on the end of the support column 3 away from the support housing 4. A second brake disc 29 is mounted on one side of the brake frame 27. An electric push rod 30 is fixedly mounted between the second brake disc 29 and the brake frame 27. A guide rod 31 is fixedly mounted on the second brake disc 29. The guide rod 31 passes through the brake frame 27 and is slidably connected to the brake frame 27. Specifically, in the event of a mechanical failure, the operation of the electric push rod 30 can drive the second brake disc 29 to press against the surface of the first brake disc 28, thereby facilitating emergency braking of the support column 3 through the friction between the first brake disc 28 and the second brake disc 29.

[0064] In this embodiment, during use, the operator places the steel coil sleeve 6 onto the support housing 4. Then, the operator uses an electric wrench to tighten the first bolt head 23, causing the threaded rod 25 to rotate. Simultaneously, the threaded engagement between the threaded rod 25 and the positioning seat 14 moves the positioning block 15 and the clamping block 24, aligning the clamping block 24 with the side wall of the steel coil sleeve 6. The operator then uses the electric wrench to tighten the first bolt head 23, causing the drive prism 22 to rotate. Simultaneously, the sliding engagement of the second gear 21 of the drive prism 22 causes the second gear 21 to rotate. Furthermore, the meshing of the first gear ring 20 with the second gear 21 and the meshing of the first gear ring 20 with the first gear 19 rotates the first gear 19 and the bidirectional screw 18. Thus, the threaded engagement of the bidirectional screw 18 with the adjusting block 16 drives the two adjusting blocks 1 in the same positioning groove. The strip sleeve 6 is moved relative to the support housing 4 by adjusting the rod 17 and pushing the positioning block 15 to move. The positioning block 15 is pressed against the surface of the strip sleeve 6 and the friction between the positioning block 15 and the inner wall of the strip sleeve 6 is used to position the strip sleeve 6 and the support housing 4. At the same time, the clamping block 24 and the positioning plate 5 cooperate to achieve auxiliary positioning of the strip sleeve 6. Then, the operator controls the first motor 12 to work. The operation of the first motor 12 can drive the second pulley to rotate, and then drive the first pulley 9 and the support column 3 to rotate through the belt. This facilitates the feeding of the strip steel raw material 7 through the support housing 4 and the strip sleeve 6. In case of mechanical failure, the operation of the electric push rod 30 can drive the second brake disc 29 to press against the surface of the first brake disc 28. The friction between the first brake disc 28 and the second brake disc 29 can be used to brake the support column 3 in an emergency.
