Description

Technical Field

[0001] This utility model relates to the field of elevator manufacturing equipment, specifically to a shearing device for elevator manufacturing. Background Technology

[0002] As a core component of vertical transportation systems, elevators have become an indispensable basic engineering tool in high-rise buildings and public facilities. With breakthroughs in computer control technology and power electronic drive technology, modern elevator systems have evolved into highly integrated mechatronic intelligent devices. Their design and manufacturing adhere to stringent safety engineering standards and employ a modular production model. After standardized manufacturing, each functional component undergoes systematic integration and debugging at the construction site for final assembly. This integration process involves the coordinated integration of precision mechanical transmission devices, intelligent electrical control systems, and the building's main structure, ultimately forming a complete transportation system that meets safety regulations.

[0003] In the raw material processing stage of elevator manufacturing, elevator-specific metal sheets need to be pre-processed and cut according to structural mechanical parameters to meet engineering component manufacturing standards. Shearing equipment is typically used to cut the thin sheets used in elevator manufacturing. Currently, during the cutting process of elevator steel sheets, misalignment occurs, leading to inaccurate cutting. Manually pressing or aligning the edges is impractical; therefore, it is necessary to develop a highly accurate shearing device. Utility Model Content

[0004] To address the aforementioned problems, the main objective of this utility model is to provide a shearing equipment for elevator manufacturing. This equipment effectively suppresses displacement deviations in the steel plates used for elevator manufacturing during processing through accurate positioning devices or structures. Furthermore, its highly automated mode reduces the degree of manual intervention, improving processing consistency while reducing repetitive labor for operators.

[0005] To achieve the above objectives, this utility model provides a shearing device for elevator manufacturing, comprising an operating platform, a pushing device, a limiting device, and a cutting device. A support is provided at the top corner of the bottom surface of the operating platform, and a feeding platform is provided at one end of the operating platform. The operating platform has a first slot and two second slots. The pushing device includes a driving roller, a driven roller, two support frames, and a first drive structure. The limiting device includes a bidirectional threaded rod, a second drive structure, two limiting rods, and two limiting plates. The bidirectional threaded rod is located in the first slot, and the two limiting rods are respectively located in the second slots. The cutting device includes a mounting plate, a hydraulic lifting column, and a cutting blade. The mounting plate is fixed to the end of the operating platform away from the feeding platform.

[0006] Furthermore, the first slot and the two second slots are parallel to the extension direction of the feeding platform, and the second slots are located at equal distances on both sides of the first slot.

[0007] Furthermore, the support frames are parallel to each other and vertically installed on the feeding platform. The drive roller is laterally located between the two support frames. The two ends of the drive roller are provided with rotating shafts, which are rotatably inserted into their corresponding support frames. Any rotating shaft is connected to the output end of the first drive structure, and the driven roller is rotatably installed between the two support frames.

[0008] Furthermore, the limiting plate includes an L-shaped plate and a first movable member and two second movable members located on the bottom surface of the L-shaped plate, with the two second movable members located on both sides of the first movable member.

[0009] Furthermore, the first moving part is provided with a threaded hole, the second moving part is provided with a limiting hole, and the two ends of the bidirectional threaded rod are respectively provided with a left-hand thread structure and a right-hand thread structure. The left-hand thread structure or the right-hand thread structure passes through its corresponding threaded hole, and the limiting rod passes through its corresponding limiting hole.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1The diagram shows the structure of the shearing equipment for elevator manufacturing according to this utility model. The shearing equipment for elevator manufacturing according to this utility model includes an operating platform 10, a pushing device, a limiting device, and a cutting device. A bracket 11 is provided at the top corner of the bottom surface of the operating platform 10. A feeding platform 12 is provided at one end of the operating platform 10. The height of the feeding platform 12 is lower than the overall height of the operating platform 10. The cutting device is located at the end of the operating platform away from the feeding platform 12. The cutting device includes a mounting plate 41, a hydraulic lifting column 42, and a cutting blade 43. The mounting plate 41 is fixed on the edge of the operating platform 10 away from the feeding platform 12. The hydraulic lifting column 42 is fixed on the mounting plate 41. The cutting blade 43 is located at the extendable end of the hydraulic lifting column 42. The steel plate for elevator manufacturing enters the feeding platform 12 and is pushed to the upper surface of the operating platform 10 by the pushing device on the feeding platform 12. The limiting device locks the steel plate and then pushes it to the cutting device for stable cutting.

[0025] Please refer to the following: Figure 1 As shown, the feeding device of this utility model includes a driving roller 21, a driven roller 22, two support frames 23, and a first drive structure 24. The two support frames 23 are parallel to each other and vertically installed on the feeding platform 12. The driven roller 22 is rotatably installed between the two support frames 23, and the driving roller 21 is laterally located between the two support frames 23. In this embodiment, the two end faces of the driving roller 21 are provided with rotating shafts, which are rotatably inserted into their corresponding support frames 23. Any rotating shaft is connected to the output end of the first drive structure 24. After the first drive structure 24 is started, it can drive the rotating shaft to rotate, thereby realizing the rotation of the driving roller 21. In other embodiments, such as... Figure 1 As shown, a conveying structure is also provided, which includes a first rotating disk, a second rotating disk and a conveyor belt. The first rotating disk is fixedly connected to the rotating shaft. The conveyor belt is simultaneously fitted on the first rotating disk and the second rotating disk. The second rotating disk is mounted on the bracket 11 through a connector. The second rotating disk is connected to the output shaft of the first drive structure 24. Thus, after the first drive structure 24 is started, the purpose of driving the active roller shaft 21 to rotate can also be achieved through the conveying structure.

[0026] The feeding device of this utility model fixes the steel plate for elevator manufacturing to be sheared between the active roller 21 and the driven roller 22. By rotating the active roller 21, the driven roller 22 also rotates under the action of friction with the steel plate, driving the steel plate to move towards the cutting device. The feeding device of this utility model is equipped with an active roller 21 and a driven roller 22. After the two rollers clamp the steel plate, they automatically feed it. In addition to providing a certain clamping force to the steel plate in the vertical direction, it also eliminates the need for repetitive manual operation steps. The rollers can also have a certain flat pressing function to pre-process the steel plate and realize the function of continuous feeding.

[0027] Please continue reading Figure 1 As shown, the operating platform 10 of this utility model is provided with a first slot 13 and two second slots 14, the first slot 13 and the two second slots 14 being parallel to the extending direction of the feeding platform 12 (e.g., Figure 1 (In the direction of the middle arrow C), the second card slot 14 is located equidistantly on both sides of the first card slot 13. Please refer to [link / reference]. Figure 1 and Figure 2 As shown, the limiting device of this utility model includes a bidirectional threaded rod 31, a second driving structure 32, two limiting rods 33, and two limiting plates 34. The bidirectional threaded rod 31 is located in the first slot 13, and the two limiting rods 33 are respectively located in the second slots 14. In addition, the limiting plate 34 is provided with an L-shaped plate 35 and a first moving part 36 and two second moving parts 37 located on the bottom surface of the L-shaped plate 35. Similarly, the two second moving parts 37 are located on both sides of the first moving part 36. The first moving part 36 is movably located in the first slot 13, and the second moving part 37 is movably located in its corresponding second slot 14. The first moving part 36 is provided with a threaded hole 361, and the second moving part 37 is provided with a limiting hole 371. The two ends of the bidirectional threaded rod 31 are respectively provided with a left-hand thread structure and a right-hand thread structure. The left-hand thread structure or the right-hand thread structure passes through its corresponding threaded hole 361, and the limiting rods 33 pass through their corresponding limiting holes 371.

[0028] Furthermore, it should be noted that one end of the bidirectional threaded rod 31 passes through the operating platform 10, and a bearing structure is provided between its contact surface with the operating platform 10. This end passing through the operating platform 10 is connected to the output shaft of the second drive structure 32. After opening the second drive structure 32, the bidirectional threaded rod 31 can be driven to rotate clockwise or counterclockwise. Since the threaded structures at both ends of the bidirectional threaded rod 31 are arranged in opposite directions, as the bidirectional threaded rod 31 rotates, the two first moving parts 36 connected to its outer circumference thread move inward simultaneously or outward synchronously. This allows the steel plate transported from the pushing device to be fixed in position on both sides (i.e., Figure 1 (Fixed in the direction of arrow C), the limiting device limits the position of the steel plate on both sides, stably fixing the steel plate on the operating platform 10, preventing horizontal positional deviation, and improving the cutting accuracy of the final product; in other preferred embodiments, the inner side of the L-shaped clamping plate 35 is provided with a positioning plate 354 (e.g. Figure 3 As shown, the positioning plate 354 is fixedly installed on the L-shaped clamping plate 35. When the two L-shaped clamping plates 35 limit the steel plate, the positioning plate 354 on them stably presses the steel plate against it, preventing it from being misaligned in the vertical direction (i.e., Figure 1 (In the direction indicated by the middle arrow D), further improving the accuracy of subsequent cutting.

[0029] In other preferred embodiments, such as Figure 3 and Figure 4 As shown, the L-shaped clamping plate 35 of the limiting device has a base plate 351, a baffle 352, an elastic structure, and a pressing plate 353. The baffle 352 is vertically fixed on the outer wall of the base plate 351, and the pressing plate 353 is located on the inner side of the baffle 352. The pressing plate 353 and the baffle 352 are connected by an elastic structure. The elastic structure can be several springs, with the two ends of the springs respectively hinged to the outer wall of the pressing plate 353 and the inner wall of the baffle 352, or it can be made of a special material with greater elasticity, which can provide buffer potential energy for the pressing plate 353. No restrictions are placed here. In addition, the base plate 351 is provided with a sliding groove 3511, and the bottom surface of the pressing plate 353 is provided with a slider 3531. The slider 3531 slides in the sliding groove 3511, or the slider 3531 is provided with pulley structures on both sides of the slider 3531, and the pulley structures can be locked in the sliding groove 3511 and slide. When the limiting device of this utility model clamps and limits the steel plate on both sides, the L-shaped clamping plate 35 has a certain buffering force through the setting of the clamping plate 353, the elastic structure and the baffle 352, so that it will not exert too strong rigid force on the steel plate, and prevent the steel plate from being damaged or causing structural damage to the shearing equipment.

[0030] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
