Description

Technical Field

[0001] This utility model relates to the field of expansion and tightening structure technology, specifically to an expansion and tightening transfer shaft for transferring rolled materials. Background Technology

[0002] Coiled steel is a continuous strip material made from steel as raw material. Its coiled form facilitates storage, transportation, and processing. Main types include sheet coils, wire coils, cold-rolled steel coils, hot-rolled steel coils, galvanized steel coils, and color-coated steel coils. Production involves processes such as annealing and solution treatment, and must comply with raw material procurement and process control standards.

[0003] Coiled materials include not only metal coils, but also coiled structures of different materials. During the production and processing of coiled materials, material transfer is required. The material transfer of coiled materials is mostly carried out by material transfer gantry or robotic arms. Both material transfer gantry and robotic arms need to pick up the coiled material. Traditional coiled material picking is mostly done by grippers. However, in actual implementation, it has been found that the grippers have insufficient gripping force when picking up coiled materials. When picking up slightly heavier coiled materials, they may fall, affecting the safety of coiled material transfer. Therefore, this utility model proposes an expansion and tensioning material transfer shaft for coiled material transfer. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning transfer shaft for transferring rolled materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensioning and transferring shaft for roll material transfer, comprising an upper end seat, a cylinder fixedly installed at the center of the outer surface of the upper end seat, a secondary end seat fixedly installed on the outer wall of the end of the cylinder away from the upper end seat, an outer bushing fixedly installed at the center of the outer surface of the secondary end seat, the outer bushing having a hollow internal structure, a telescopic piston rod provided at the output end of the cylinder, the top end of the piston rod being inserted into the outer bushing and connected to a push rod, the push rod being movably connected to the outer bushing, two sets of drive sleeves fixedly sleeved on the outer surface of the push rod, each of the two drive sleeves having several inclined grooves on its outer surface, each inclined groove having a sliding contact with a material-ejecting wedge, the material-ejecting wedge having a material-ejecting inclined surface adapted to the inclined groove, and a tensioning block installed on the outer surface of the material-ejecting wedge.

[0018] 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.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a tensioning transfer shaft for transferring rolled materials, including an upper end seat 1. A cylinder 2 is fixedly installed at the center of the outer surface of the upper end seat 1. The cylinder 2 can provide power for the tensioning of the transfer shaft of this utility model. A secondary end seat 3 is fixedly installed on the outer wall of the end of the cylinder 2 away from the upper end seat 1. An outer bushing 4 is fixedly installed at the center of the outer surface of the secondary end seat 3. The inner part of the outer bushing 4 is hollow. A telescopic piston rod 5 is provided at the output end of the cylinder 2. The top end of the piston rod 5 is inserted into the outer bushing 4 and connected to a push rod 6. The push rod 6 is movably connected to the outer bushing 4. Thus, when the piston rod 5 is extended or retracted under the driving action of the cylinder 2, the piston rod 5 can drive the push rod 6 to move left and right. Thus, the left and right movement of the push rod 6 can provide a driving effect for the tensioning and contraction of the shaft.

[0022] Furthermore, two sets of drive sleeves 7 are fixedly sleeved on the outer surface of the push rod 6. Several inclined grooves 10 are opened on the outer surface of the two drive sleeves 7. The several inclined grooves 10 are circumferentially distributed at equal intervals through the center point of the drive sleeve 7. Each inclined groove 10 has a push wedge 8 in sliding contact. The push wedge 8 is provided with a push inclined surface adapted to the inclined groove 10. An expansion block 9 is installed on the outer surface of the push wedge 8. The push wedge 8 and the expansion block 9 are both limited and slidably connected to the outer bushing 4.

[0023] Based on the above structural description, when the expansion and transfer shaft of this utility model is performing expansion work, the piston rod 5 can be driven by the cylinder 2 to retract. See the appendix of the instruction manual for details. Figure 3As shown, when the piston rod 5 retracts, the piston rod 5 can drive the top rod 6 at the top to move from left to right. The displacement of the top rod 6 from left to right can drive the drive sleeve 7 to move. During the movement of the drive sleeve 7, it can push the top wedge block 8 through the inclined groove 10. By pushing up the top wedge block 8, the expansion block 9 can be pushed out from the outer bushing 4, thus completing the normal expansion and tightening work of this utility model.

[0024] In this embodiment, in order to improve the auxiliary reset effect, a conical head 11 is fixedly installed on the outer surface of the top end of the outer bushing 4, and a spring 12 is fixedly installed between the top drive sleeve 7 and the conical head 11. With this structural design, during the movement of the drive sleeve 7 from left to right, the top drive sleeve 7 can stretch the spring 12, so that the spring 12 is in a stretched state. After the cylinder 2 stops working, the stretched spring 12 resets, so that the push rod 6 can be pulled by the drive sleeve 7 from right to left for reset processing.

[0025] In this embodiment, in order to facilitate the installation of the transfer shaft, the outer surface of the upper end seat 1 is provided with several mounting holes for the installation of the shaft assembly. In use, it can be installed on an external robot or transfer gantry through the mounting holes provided on the upper end seat 1, so that the transfer can be easily carried out through an external drive structure.

[0026] Working principle: When the expansion and transfer shaft of this utility model is in use, it can be installed on an external robot or transfer gantry through the mounting hole provided on the upper end seat 1, so as to facilitate material transfer work through an external drive structure;

[0027] During the transfer of the rolled material, an external robotic arm or transfer gantry inserts the outer bushing 4 of this invention into the central circular hole of the rolled material. Then, the cylinder 2 operates. During tightening, the cylinder 2 drives the piston rod 5 to retract. See the attached instruction manual for details. Figure 3 As shown, when the piston rod 5 retracts, the piston rod 5 can drive the top rod 6 at the top to move from left to right. The displacement of the top rod 6 from left to right can drive the drive sleeve 7 to move. During the movement of the drive sleeve 7, it can push the top wedge 8 through the inclined groove 10. The pushed top wedge 8 can drive the expansion block 9 to be pushed out from the outer bushing 4, thus completing the normal expansion and tightening work of this utility model.

[0028] The material transfer shaft in the bulging state can expand and open in the center hole of the roll material to complete the bulging and material handling work of the roll material. Afterwards, the material is transferred and transported by an external robot or material transfer gantry, ensuring the normal bulging and material transfer use of the material transfer shaft of this utility model.

[0029] Based on the above structure, the expansion and transfer shaft of this utility model can be used in conjunction with an external robotic arm or transfer gantry to achieve the pneumatic expansion and transfer effect of the rolled material. It can complete the insertion-type expansion and transfer of the rolled material. Compared with the traditional gripper for rolling material handling, this utility model has a better and more stable material handling and transfer effect through the insertion-type expansion and transfer. The expansion and support of the expansion shaft can transmit torque and axial force, and it can withstand a greater load during expansion and transfer. It is suitable for high-intensity working conditions, avoids the problem of falling due to insufficient gripping force of traditional grippers, improves the safety of rolling material transfer, reduces safety hazards, and has better overall practicality and stronger stability.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
