Description

Technical Field

[0001] This utility model relates to the field of unwinding and leveling machines, and more specifically, to a material rack hydraulic expansion mechanism. Background Technology

[0002] Uncoiling machines are specialized equipment for leveling metal sheets. They are used to level steel plates and uneven plates. Depending on the configuration, they can be used to form uncoiling, leveling, and shearing production lines and other sheet metal product production lines. Uncoiling machines are suitable for industries such as machinery, vehicles, metal products, household appliances, steel structures, and decoration. Some existing uncoiling machines use material racks to support and fix the steel coils through a hydraulic expansion mechanism.

[0003] However, some existing hydraulic expansion mechanisms for material racks lack a stop structure. After the steel coil is placed on the hydraulic expansion mechanism, it rotates synchronously with the mechanism to unwind the steel material. During the unwinding process, the steel material may shift, potentially causing the coil to loosen, which is inconvenient for subsequent processing and reduces the unwinding efficiency of the equipment. Therefore, we propose a new hydraulic expansion mechanism for material racks. Utility Model Content

[0004] To solve the above problems, this utility model provides a material rack hydraulic expansion mechanism, which adopts the following technical solution:

[0005] A material rack hydraulic expansion mechanism includes a base, two symmetrically distributed base frames are fixedly installed at the bottom of the base, and a hydraulic expansion assembly is provided on one side of the base;

[0006] The hydraulic expansion assembly includes a rotating shaft rotatably mounted on one side of the base. The side wall of the rotating shaft is provided with four expansion plates arranged in a ring array. There are two hydraulic rods symmetrically distributed between the inner side of the expansion plates and the side wall of the rotating shaft. The side wall of the rotating shaft is provided with four sliding grooves arranged in a ring array, and each sliding groove is provided with a stop assembly.

[0007] By adopting the above technical solution, when using this equipment, the operator places the steel coil on the side wall of the hydraulic expansion assembly using the existing feeding structure. The hydraulic system drives the hydraulic rod to move, which in turn drives the expansion plate on the same side to move, so that the four expansion plates fit tightly against the inside of the steel coil, thus supporting and fixing the steel coil. After the steel coil is fixed, the operator places the stop assembly in the groove opened on the side wall of the rotating shaft, so that the stop assembly contacts the opposite side of the steel coil, thus restricting and stabilizing the steel coil and helping to maintain the stability of the steel coil during unwinding.

[0008] Furthermore, the gear shift assembly includes a slider that is slidably installed in the slide groove. A retaining frame is fixedly installed on the side of the slider away from the rotating shaft. A roller is rotatably installed in the retaining frame. A screw hole is opened in the slider and a bolt is installed in the screw hole. A groove is opened on the inner wall of the slide groove away from the retaining frame on the same side. An anti-slip pad is provided on the inner wall of the groove. The end of the bolt extends into the groove on the same side.

[0009] By adopting the above technical solution, after the steel coil is supported, the worker places the slider in the groove opened on the side wall of the rotating shaft. A baffle is provided on the side of the slider away from the rotating shaft. The worker adjusts the position of the slider in the groove on the same side so that the baffle contacts the side of the steel coil opposite to it. Then, the bolt is placed in the screw hole opened on the side wall of the slider. The inner wall of the groove is provided with an anti-slip pad, so that the width of the groove is smaller than the diameter of the bolt. By continuously rotating the bolt, the end of the bolt is placed in the groove opened on the inner wall of the groove on the same side. Through the combination of the bolt, the groove and the anti-slip pad, the slider can be fixed, which in turn can fix the baffle. The baffle restricts and positions the steel coil, which helps to maintain the stability of the steel coil during unwinding.

[0010] Furthermore, two symmetrically distributed slide rods are fixedly installed in each slide groove, and the ends of the two slide rods on the same side that are away from the machine base slide through the slider on the same side.

[0011] By adopting the above technical solution, a sliding rod is provided in the slide groove. When the operator places the slider in the slide groove, the slider slides and is fitted onto the side wall of the sliding rod. The sliding rod restricts and positions the slider, which helps to maintain the stability of the slider's sliding.

[0012] Furthermore, a baffle is fixedly fitted on the side wall of the shaft near the base. The side wall of the baffle has four baffles arranged in a circular array, and the four baffles and the baffle are fixed together by screws.

[0013] By adopting the above technical solution, the side wall of the rotating shaft is equipped with a baffle, and the side wall of the baffle is equipped with a baffle frame. Through the cooperation of the baffle, the baffle frame and the baffle frame, the steel coil displacement is restricted. The baffle and the baffle are fixed with screws, which facilitates subsequent disassembly and maintenance.

[0014] Furthermore, positioning blocks are fixedly installed on the side of the baffle close to the baffle plate, and positioning grooves matching the positioning blocks are opened on the side wall of the baffle plate.

[0015] By adopting the above technical solution, when installing the baffle, the workers will fit the baffle against the side wall of the baffle plate. The baffle is provided with a positioning block on the side near the baffle plate. The positioning block and the positioning groove opened on the side wall of the baffle plate will engage to position the baffle, which will facilitate subsequent fixing.

[0016] Furthermore, multiple rubber pads arranged in a straight array are fixedly installed on the side of each of the four expansion plates away from the pivot, and a counterweight is fixedly installed on the bottom of the base away from the pivot.

[0017] By adopting the above technical solution, a rubber pad is provided on the side of the expansion plate away from the rotating shaft, which helps to increase the friction between the expansion plate and the inner side of the steel coil and helps to maintain the stability of the steel coil support. A counterweight is provided on one side of the machine base, which helps to maintain the stability of the machine base during use.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] (1) In this utility model, the side wall of the rotating shaft is set by a stop assembly. After the steel coil is fixed by the expansion plate, the worker places the slider in the groove opened on the side wall of the rotating shaft, adjusts the position of the slider, and then passes the bolt through the slider and extends into the groove. The groove is provided with an anti-slip pad. The squeezing force generated between the bolt and the groove and the anti-slip pad can fix the slider and the stop frame, thereby limiting the steel coil and helping to maintain the stability of the subsequent rotation of the steel coil.

[0020] (2) In this utility model, the side wall of the rotating shaft is provided with a baffle plate, and the side wall of the baffle plate is provided with a baffle frame. Through the cooperation of the baffle plate, the baffle frame and the baffle frame, the steel coil is restricted and stabilized. When the baffle frame and the baffle plate are set separately, it is convenient for subsequent disassembly and maintenance. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0031] Please see Figure 1-4 A material rack hydraulic expansion mechanism includes a base 1, with two symmetrically distributed base frames 3 fixedly installed at the bottom of the base 1. A hydraulic expansion assembly 2 is provided on one side of the base 1. The hydraulic expansion assembly 2 includes a rotating shaft 21 rotatably mounted on one side of the base 1. The side wall of the rotating shaft 21 is provided with four expansion plates 23 arranged in a ring array. Two symmetrically distributed hydraulic rods 22 are provided between the inner side of the expansion plates 23 and the side wall of the rotating shaft 21. When the equipment is in use, the operator places the steel coil on the side wall of the hydraulic expansion assembly 2 using the existing feeding structure. The hydraulic rods 22 are driven to move by the existing hydraulic system. The hydraulic rods 22 drive the expansion plates 23 on the same side to move, so that the four expansion plates 23 are tightly fitted with the inner side of the steel coil, thereby supporting and fixing the steel coil.

[0032] Each of the four expansion plates 23 has multiple rubber pads arranged in a straight array fixedly installed on the side away from the rotating shaft 21. A counterweight is fixedly installed on the bottom of the base 1 on the side away from the rotating shaft 21. The rubber pads on the side of the expansion plates 23 away from the rotating shaft 21 help to increase the friction between the expansion plates 23 and the inner side of the steel coil, which helps to maintain the stability of the steel coil support. The counterweight on one side of the base 1 helps to maintain the stability of the base 1 during use.

[0033] A baffle 5 is fixedly fitted on the side wall of the rotating shaft 21 near the base 1. The side wall of the baffle 5 has four baffles 6 arranged in a circular array. The four baffles 6 and the baffle 5 are fixed together by screws. The side wall of the rotating shaft 21 has four slide grooves 211 arranged in a circular array. Each slide groove 211 has a stop assembly. The stop assembly includes a slider 7 that is slidably installed in the slide groove 211. A baffle frame 4 is fixedly installed on the side of the slider 7 away from the rotating shaft 21. A roller 41 is rotatably installed in each baffle frame 4. Each slider 7 has a screw hole. Each screw hole has a bolt 8. A groove 2111 is opened on the inner wall of the slide groove 211 away from the baffle frame 4 on the same side. The inner wall of the groove 2111 is provided with an anti-slip pad. The end of the bolt 8 extends into the groove 2111 on the same side.

[0034] After the steel coil is supported, the worker places the slider 7 into the groove 211 on the side wall of the rotating shaft 21. A retaining frame 4 is located on the side of the slider 7 away from the rotating shaft 21. The worker adjusts the position of the slider 7 within the groove 211 on the same side so that the retaining frame 4 contacts the opposite side of the steel coil. Then, the bolt 8 is placed into the screw hole on the side wall of the slider 7. An anti-slip pad is provided on the inner wall of the groove 2111, ensuring that the width of the groove 2111 is less than the diameter of the bolt 8. By continuously rotating the bolt 8, the end of the bolt 8 is positioned within the groove 211 on the same side. The groove 2111 on the inner wall of the shaft 21, through the combination of bolt 8, groove 2111 and anti-slip pad, can fix the slider 7, and thus fix the baffle 4. The baffle 4 restricts the positioning of the steel coil, which helps to maintain the stability of the steel coil during unwinding. The side wall of the shaft 21 is provided with a baffle 5, and the side wall of the baffle 5 is provided with a baffle 6. Through the cooperation of the baffle 5, the baffle 6 and the baffle 4, the steel coil is restricted from deflection. The baffle 6 and the baffle 5 are fixed with screws, which facilitates subsequent disassembly and maintenance.

[0035] Two symmetrically distributed slide rods are fixedly installed in each slide groove 211. The ends of the two slide rods on the same side that are away from the machine base 1 slide through the slider 7 on the same side. When the slide rods are installed in the slide groove 211, the slider 7 slides and is fitted onto the side wall of the slide rod. The slide rods restrict and position the slider 7, which helps to maintain the stability of the slider 7.

[0036] Positioning blocks 61 are fixedly installed on the side of the baffle 6 near the baffle 5. The side wall of the baffle 5 has a positioning groove that matches the positioning blocks 61. When installing the baffle 6, the workers will fit the baffle 6 against the side wall of the baffle 5. The positioning blocks 61 on the side of the baffle 6 near the baffle 5 will engage with the positioning grooves on the side wall of the baffle 5 to position the baffle 6 and facilitate subsequent fixing.

[0037] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator places the steel coil on the side wall of the hydraulic expansion component 2 using the existing feeding structure. The hydraulic rod 22 is driven to move by the existing hydraulic system, and the expansion plate 23 on the same side is driven to move by the hydraulic rod 22, so that the four expansion plates 23 are tightly attached to the inside of the steel coil, which can play the role of supporting and fixing the steel coil. After the steel coil is fixed, the operator places the stop component in the slide groove 211 opened on the side wall of the rotating shaft 21, so that the stop component contacts the side opposite to the steel coil, which can play the role of restricting and stabilizing the steel coil, which is conducive to maintaining the stability of the steel coil when unwinding.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
