Description

Technical Field

[0001] This utility model relates to the technical field of steel formwork cutting, and in particular to a steel formwork cutting device. Background Technology

[0002] Steel formwork, as a key component in concrete pouring and forming, is widely used in the construction engineering field due to its advantages such as high reusability and stable forming quality. Traditional steel formwork is mainly manufactured by steel formwork factories through processes such as CNC punching and laser cutting of high-quality steel plates.

[0003] In the steel formwork production process, the plate cutting step requires CNC cutting equipment with precision positioning capabilities. This type of equipment is typically equipped with a slider clamping mechanism driven by a bidirectional threaded rod, using adjustable clamping plate assemblies to stably fix steel plates of different specifications. However, after completing the plate cutting operation, existing cutting equipment leaves a large amount of irregularly shaped metal scraps on its worktable. Currently, common cleaning methods fall into two categories: one is a mechanized cleaning system consisting of an electric lifting rod, vacuum pump, and suction cups; the other is entirely reliant on manual handling for cleaning.

[0004] The aforementioned existing technologies have significant drawbacks: (1) the mechanized cleaning system requires the entire board to be removed before it can operate, resulting in production interruption; (2) the vacuum adsorption method lacks stability in grasping irregularly shaped scraps, requiring repeated operation; (3) the manual cleaning method is not only inefficient but also poses a safety hazard of metal burrs scratching operators. These problems seriously affect the continuous operation efficiency and safety level of the steel formwork production line. Utility Model Content

[0005] The present invention aims to solve the problems of low cleaning efficiency and safety hazards caused by irregular metal scraps remaining on the worktable in existing steel formwork cutting equipment.

[0006] To achieve the above objectives, this application proposes a steel formwork cutting device, including a support frame and a conveying worktable disposed on top of the support frame.

[0007] The conveying workbench is composed of several segmented working units arranged at equal intervals along the conveying direction of the steel template. Each segmented working unit includes:

[0008] The platform assembly includes two inclined platforms arranged symmetrically on the left and right sides, with the inner edges of the two inclined platforms hinged to the crossbeams of the support frame via connectors.

[0009] The conveying mechanism includes multiple sets of rollers that are equally spaced and embedded on the surface of an inclined platform. The rollers are cylindrical and their axes are perpendicular to the surface of the platform.

[0010] The drive mechanism has a mounting lug at the cylinder end, which is connected to the inner wall of the support frame via a first hinge seat, and the piston rod end is connected to the bottom of the inclined platform via a second hinge seat.

[0011] The material collection device is located at the bottom of the support frame between adjacent segmented working units, and its top opening corresponds to the inclined falling trajectory of the inclined platform.

[0012] The steel formwork cutting device provided in this application precisely controls the tilt angle of the inclined table through a drive mechanism. It uses gravity to make the scrap generated by cutting automatically slide down the surface of the inclined table to the collection device. At the same time, the rollers arranged at equal intervals form a continuous and stable support plane, maintaining the horizontal conveying state of the steel formwork during the scrap removal process. This effectively solves the problems of low cleaning efficiency and safety hazards of metal debris flying caused by scrap remaining on the worktable in traditional cutting equipment.

[0013] As an improvement to the aforementioned rollers, in order to reduce the friction during horizontal transport of the steel template, the rollers are made of tungsten carbide hard alloy and the surface is polished to form a mirror finish.

[0014] Furthermore, in order for the cutting device to be able to select different drive mechanisms according to the usage conditions, the drive mechanism can be any one of a hydraulic cylinder, an electric push rod, a pneumatic cylinder, a screw jack, or a linear motor.

[0015] Furthermore, in order to facilitate monitoring of the tilt angle of the tilting platform, the steel template cutting device also includes an angle sensor, which is set at the connector and electrically connected to the control system of the drive mechanism to provide real-time feedback on the tilt angle of the tilting platform.

[0016] Furthermore, as an improvement to the above-mentioned collecting device, the collecting device includes:

[0017] The deflector has an angle of 45°-60°.

[0018] The collection bin is equipped with a cushioning rubber pad on top.

[0019] The surface of the deflector plate is provided with staggered raised stripes.

[0020] Furthermore, in order to adapt different steel formwork cutting devices to steel formwork of different sizes, the spacing between adjacent segmented working units is 1 / 8 to 1 / 6 of the length of the steel formwork, and the width of each segmented working unit is 300-400mm.

[0021] Furthermore, in order to reduce the friction between the inclined platform and the connecting piece, the connecting piece is equipped with a self-lubricating bearing. The outer ring of the bearing is interference-fitted with the crossbeam, and the inner ring is clearance-fitted with the inclined platform.

[0022] Furthermore, it also includes splash guards, which are hinged to the crossbeams on both sides of the support frame and can be extended to a working position at a 30° angle to the horizontal plane.

[0023] Furthermore, to prevent iron filings from flying during the steel template processing, the splash guard is made of transparent polycarbonate material and has magnetic sealing strips on its edges.

[0024] The beneficial effects of this application are as follows:

[0025] 1. The steel formwork cutting device provided in this application precisely controls the tilt angle of the inclined table through a drive mechanism. It uses gravity to make the scrap generated by cutting automatically slide down the surface of the inclined table to the collection device. At the same time, the rollers arranged at equal intervals form a continuous and stable support plane, maintaining the horizontal conveying state of the steel formwork during the scrap removal process. This effectively solves the problems of low cleaning efficiency and safety hazards of metal debris flying due to scrap stagnation on the worktable in traditional cutting equipment.

[0026] 2. The drive mechanism of this application is arranged on the bottom surface of the inclined platform, forming a deformable triangular support structure. This structure, together with the inclined platform and the inner wall of the support frame, forms a dynamically stable mechanical support system. Simultaneously, the inclined platform acts as a natural protective barrier, effectively preventing the impact of falling scrap materials on the drive mechanism. This structural design significantly improves the service life of key components while ensuring equipment stability.

[0027] 3. The material collection device of this application adopts multi-stage buffering technology. The primary deceleration is achieved by tilting the guide plate. The raised stripes on the surface of the guide plate form a turbulence effect, which transforms the free fall motion into controllable sliding. Combined with the buffer rubber pad, it effectively reduces the impact force of scrap materials and significantly extends the service life of the equipment.

[0028] 4. The splash-proof system of this application includes a transparent splash-proof baffle and a magnetic sealing structure, which can effectively block splashing particles and achieve physical isolation between the working area and the non-working area, significantly reducing the dust concentration in the operating area and improving the safety of the working environment.

[0042] The following will be combined with the appendix Figures 1-5 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0043] Example 1:

[0044] like Figures 1-5 This illustration shows a steel formwork cutting device according to this application. The steel formwork cutting device provided by this application is equipped with a segmented conveying worktable. The conveying worktable consists of several segmented working units 10 arranged at equal intervals along the conveying direction of the steel formwork. Each segmented working unit 10 includes a table assembly 20, a conveying mechanism 30, a driving mechanism 40, and a material collection device 50.

[0045] Please continue to refer to Figure 2 , Figure 2The structure of the table assembly 20 is illustrated. The table assembly 20 consists of two symmetrically arranged inclined table plates 21. The inner edges of these two inclined table plates 21 are hinged to the crossbeam 11 of the support frame 1 via connectors 22. When the drive mechanism 40 retracts, it drives the inclined table plates 21 to tilt outwards around the connectors 22, allowing the scrap material generated during cutting to slide down the table surface to the collection device 50. Simultaneously, the tops of the rollers 31 in the conveying mechanism 30 form a continuous support surface, maintaining the horizontal conveying state of the steel template during the tilting process. This design not only solves the problem of low cleaning efficiency caused by scrap material remaining on the worktable but also avoids the safety hazard of flying metal shavings.

[0046] As a preferred embodiment, the angle at which the inclined table 21 can be tilted outward around the connector 22 when the drive mechanism 40 retracts can be preset according to the actual production situation. Preferably, the tilt angle is 12°-15° to ensure that the scrap generated by cutting can slide smoothly down the table surface to the collection device 50.

[0047] Please refer to Figure 3 , Figure 3 The installation position of the angle sensor 43 is illustrated. To monitor the tilt angle of the tilting platform 21 in real time, this application provides the angle sensor 43 at the connector 22. The angle sensor 43 is electrically connected to the control system of the drive mechanism 40, enabling real-time feedback of the tilt angle of the tilting platform 21. This design allows the control system to precisely control the extension and retraction of the drive mechanism 40 based on the feedback data from the angle sensor, thereby ensuring that the tilt angle of the tilting platform 21 remains within the set range.

[0048] Please continue to refer to Figure 3 In the embodiments of this application, in order to reduce the friction between the tilting platform 21 and the connecting member 22, a self-lubricating bearing 23 is embedded in the connecting member 22. The outer ring of the bearing is interference-fitted with the crossbeam 11, and the inner ring is clearance-fitted with the tilting platform 21. This design not only improves the rotational flexibility of the tilting platform 21, but also reduces frictional losses and noise during rotation.

[0049] Example 2:

[0050] like Figures 1-5 This illustration shows a steel formwork cutting device according to this application. To reduce the friction of the steel formwork during horizontal transport, the roller 31 is made of tungsten carbide hard alloy and polished to achieve a mirror finish. This material selection and surface treatment process give the roller 31 extremely high hardness and smoothness, thereby effectively reducing the frictional resistance of the steel formwork during transport.

[0051] Optionally, in this application, the drive mechanism 40 can be any one of a hydraulic cylinder, an electric actuator, a pneumatic cylinder, a screw jack, or a linear motor. This design allows the cutting device to select a suitable drive method according to the specific usage environment and requirements, thereby improving the adaptability and flexibility of the equipment.

[0052] Please refer to Figure 4 , Figure 4 The structure of the material collection device 50 is illustrated. The design of the material collection device 50 fully considers the collection and buffering of scrap materials. The material collection device 50 includes a guide plate 51 and a collection box 53. The guide plate 51 has an inclination angle of 45°-60°, which allows scrap materials to slide smoothly into the collection box 53. Simultaneously, the surface of the guide plate 51 is provided with staggered raised stripes 52. These stripes can create a turbulence effect, transforming free fall motion into controlled sliding, further reducing the impact force of the scrap materials. The top of the collection box 53 is equipped with a buffer rubber pad 54, which can effectively absorb the impact energy of the scrap materials and protect the collection box 53 from damage.

[0053] As a preferred solution, to accommodate steel formwork of different sizes, this application optimizes the spacing and width of the segmented working units 10. The spacing between adjacent segmented working units 10 is 1 / 8 to 1 / 6 of the length of the steel formwork. This spacing design ensures the stability of the steel formwork during transportation and facilitates the sliding and collection of scrap materials. Simultaneously, the width of each segmented working unit 10 is 300-400 mm, a width design that allows the cutting device to be adapted to steel formwork of different widths.

[0054] Example 3:

[0055] like Figures 1-2 The illustration shows the installation position of the splash guard 60 of this application. The design of the splash guard 60 further improves the safety of the cutting device and the quality of the working environment. The splash guard 60 is hinged to the crossbeams 11 on both sides of the support frame 1 and can be unfolded to a working position at a 30° angle to the horizontal plane. This design allows the splash guard 60 to effectively block flying iron filings and scraps, preventing them from causing pollution and injury to the working area. At the same time, the splash guard 60 is made of transparent polycarbonate material, and its edges are equipped with magnetic sealing strips 61, which can ensure physical isolation between the working area and the non-working area and reduce the dust concentration in the operating area.
