Description

Technical Field

[0001] The utility model relates to the technical field of discharging racks, in particular to a discharging rack for producing stainless steel pipes. Background Technique

[0002] Most of the stainless steel pipes on the market are formed by folding. The two sides of the steel strip pulled out from the metal coil are rolled up and then welded to form a hollow stainless steel pipe. In current production applications, people use a coil discharging rack to place the metal coil. The traditional coil discharging rack simply hangs the metal coil on a rod. As the production equipment pulls the steel strip, the steel strip will be pulled out from the metal coil. However, when pulling, since the diameter of the rod is different from the center size of the metal coil, the center of the metal coil will continuously jump, resulting in violent shaking of the entire metal coil, large vibrations and loud noises on the production line. Therefore, people further improved the support shaft of the discharging rack and designed the support shaft as a movable shaft with a variable shaft diameter. Before putting the metal coil on the movable shaft, the diameter of the movable shaft is set to the minimum. After putting the metal coil on the movable shaft, the diameter of the movable shaft becomes larger to support the central hole of the metal coil, so that the entire metal coil rotates along the center of the metal coil during rotation, avoiding vibrations during the rotation of the metal coil and making the output of the steel strip from the metal coil more stable. However, the current discharging racks on the market have a too complex mechanism in the design of the movable shaft, which increases the difficulty of production and assembly. Moreover, with a large number of components, once damaged during use, the work of replacing components will be very cumbersome, thus occupying the maintenance time of the production line.

[0003] The technical content disclosed in the Chinese patent document (Publication No.: CN206407755U, Patent Name: Metal Coil Unloading Rack) is as follows: A metal coil unloading rack includes a central rotating shaft. One end of the central rotating shaft is connected to a hydraulic cylinder, and the hydraulic cylinder is connected to a support mechanism at the other end of the central rotating shaft. The support mechanism includes a support body with a rectangular cross-section. Sliding blocks are connected to the four side surfaces of the support body. The sliding block includes an upper sliding block and a lower sliding block that contact through a guide rail. The contact surface between the upper sliding block and the lower sliding block is an inclined surface, and the end of the inclined surface close to the hydraulic cylinder is the lower end. A protrusion is provided at the other end of the upper sliding block, and the protrusion is connected to an arc-shaped support plate through a groove. The groove is provided on the inner arc side of the support plate. The end of the support plate close to the hydraulic cylinder is connected to a circular baffle through a sliding plate. A sliding groove is provided on the baffle corresponding to the support plate. A limiting strip is provided at the other end of the support plate. Four sliding blocks are arranged in a row as a group at the center of the side surface of the support body. The sliding plate is arranged on both sides of the circular baffle. A slide rail corresponding to the sliding plate is provided on the side of the circular baffle close to the hydraulic cylinder. One end of the limiting strip is provided with an arc-shaped inclination, and the arc-shaped inclined end is the coil loading end. The circular baffle is also provided with a cross-shaped stop block. The hydraulic rod of the hydraulic cylinder passes through the central rotating shaft and is connected to a sliding rod, and the sliding rod is connected to the upper sliding block through a rocker.

[0004] As can be seen from the above implementation, the metal coil unloading rack is provided with a central rotating shaft, and inclined slide rails that are slidably connected to each other are arranged on the central rotating shaft. Therefore, when the two inclined slide rails slide, the diameter of the cylinder formed by the arc-shaped support plate will also change. Among them, the upper sliding block is connected by a rocker and is pushed to slide through a sliding rod. Therefore, this metal coil unloading rack has many components and a complex structure, which will cause many difficulties in production and assembly. And once the components are damaged due to long years of use, it will also be very difficult to repair. Utility Model Content

[0033] The following is a description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] As Figures 1 to 5 shown, a feeding rack for producing stainless steel pipes includes a support rod 3. A movable rod 4 is movably inserted inside the support rod 3. A movable sleeve shaft 6 is movably sleeved outside the support rod 3. One end of the movable rod 4 is rotatably connected to a movable connecting block 5. The movable connecting block 5 is connected to the movable sleeve shaft 6. The movable sleeve shaft 6 is rotatably connected to the support rod 3. Therefore, when the movable rod 4 moves, it drives the movable sleeve shaft 6 to move, and the movable sleeve shaft 6 can rotate relative to the support rod 3. So after the metal coil is placed on the feeding rack, when the steel bar is pulled out, the metal coil can be driven by the steel bar to rotate.

[0035] The support rod 3 is connected to the expansion and contraction chassis assembly 7. The expansion and contraction chassis assembly 7 is connected to the expansion and contraction blade assembly 8. The expansion and contraction blade assembly 8 is circumferentially arranged on one side of the expansion and contraction chassis assembly 7. The expansion and contraction blade assembly 8 includes a sleeve shaft connecting rod 803. The sleeve shaft connecting rod 803 is connected to the movable sleeve shaft 6. Not less than one swing rod 802 is rotatably connected to the sleeve shaft connecting rod 803. The other end of the swing rod 802 is connected to the blade connecting rod 801. The blade connecting rod 801 is connected to the expansion and contraction arc blade 806; thus realizing that the expansion and contraction arc blade 806 moves closer to the middle or spreads out to the surrounding. This feeding rack has a simple structure, so the production and processing cost is low, and the assembly time is short, which is beneficial for the factory to promote and use.

[0036] The telescopic chassis assembly 7 includes a chassis 701, on which there are provided not less than one long slot 7011. One end of the long slot 7011 faces the center of the chassis 701, and the long slot 7011 coincides with the radius line of the chassis 701. The blade connecting rod 801 is slidably inserted into the long slot 7011. One end of the blade connecting rod 801 is connected with an inner pull shaft 804 and an outer pull shaft 805. The inner pull shaft 804 is located on the side of the chassis 701 close to the movable sleeve shaft 6, and the outer pull shaft 805 is located on the side of the chassis 701 far from the movable sleeve shaft 6. Both the inner pull shaft 804 and the outer pull shaft 805 are perpendicular to the blade connecting rod 801. Therefore, the inner pull shaft 804 and the outer pull shaft 805 can limit the position of the blade connecting rod 801, so that one end of the blade connecting rod 801 can only slide in the long slot 7011 and will not come out of the long slot 7011.

[0037] A buffer cushion block 702 is arranged between the movable sleeve shaft 6 and the chassis 701. The buffer cushion block 702 is made of rubber material, which greatly reduces the sound generated by the impact between the movable sleeve shaft 6 and the chassis 701, reduces the noise in the workshop, and at the same time can also prevent the situation that the mounting bolts of the feeding rack become loose due to the long-term impact between the movable sleeve shaft 6 and the chassis 701.

[0038] One end of the movable rod 4 is connected with the telescopic power mechanism 2, and the telescopic power mechanism 2 is a cylinder or an oil cylinder. Therefore, the telescopic power mechanism 2 can push the movable rod 4 to move in the support rod 3, so as to drive the movable sleeve shaft 6 to move through the movable connection block 5.

[0039] The support rod 3 and the telescopic power mechanism 2 are both connected with the feeding base frame 1.

[0040] In the first embodiment, when the movable sleeve shaft 6 moves towards the chassis 701, one end of the swing rod 802 close to the movable sleeve shaft 6 also moves towards the chassis 701. The swing rod 802 changes from being perpendicular to the movable sleeve shaft 6 to having an angle less than ninety degrees with the movable sleeve shaft 6. The blade connecting rod 801 moves towards the center of the chassis 701, and the telescopic arc-shaped blade 806 moves towards the direction of the movable sleeve shaft 6. The outer diameter of the cylinder formed by several telescopic arc-shaped blades 806 becomes smaller. At this time, the metal coil can be hung on the cylinder formed by the telescopic arc-shaped blades 806. Then, when the movable sleeve shaft 6 moves away from the chassis 701, one end of the swing rod 802 close to the movable sleeve shaft 6 also moves away from the chassis 701 until the swing rod 802 is perpendicular to the movable sleeve shaft 6. The blade connecting rod 801 moves towards the direction away from the center of the chassis 701, and the telescopic arc-shaped blade 806 moves towards the direction away from the movable sleeve shaft 6 until the swing rod 802 is perpendicular to the movable sleeve shaft 6. The outer diameter of the cylinder formed by several telescopic arc-shaped blades 806 becomes larger. At this time, the inner hole of the metal coil supported by the cylinder formed by the telescopic arc-shaped blades 806 is held, so that when the metal coil rotates, the center of the metal coil is coaxial with the rotation axis, and thus when the metal coil rotates, the entire feeding rack does not jump.

[0041] In the second embodiment, the movable sleeve shaft 6 moves towards the chassis 701. One end of the swing rod 802 close to the movable sleeve shaft 6 also moves towards the chassis 701. The swing rod 802 changes from being perpendicular to the movable sleeve shaft 6 to having an angle less than ninety degrees with the movable sleeve shaft 6. The blade connecting rod 801 moves towards the center of the chassis 701. The expandable and contractible arc-shaped blades 806 move towards the movable sleeve shaft 6, and the outer diameter of the cylinder formed by several expandable and contractible arc-shaped blades 806 becomes smaller. At this time, the metal coil can be hung on the cylinder formed by the expandable and contractible arc-shaped blades 806. The movable sleeve shaft 6 moves towards the chassis 701, and one end of the swing rod 802 close to the movable sleeve shaft 6 also moves towards the chassis 701 until the swing rod 802 is perpendicular to the movable sleeve shaft 6. The blade connecting rod 801 moves away from the center of the chassis 701, and the expandable and contractible arc-shaped blades 806 move away from the movable sleeve shaft 6. The outer diameter of the cylinder formed by several expandable and contractible arc-shaped blades 806 becomes larger. At this time, the inner hole of the metal coil is supported by the cylinder formed by the expandable and contractible arc-shaped blades 806, so that when the metal coil rotates, the center of the metal coil is coaxial with the rotation axis, and thus when the metal coil rotates, the entire unwinding rack does not jump.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
