Description

Technical Field

[0001] This utility model relates to the technical field of steel plate shearing machines, specifically to a processing protection mechanism for a steel plate shearing machine. Background Technology

[0002] In the metal processing industry, steel plate shearing machines are widely used in the shearing process of steel plates. Traditional steel plate shearing machines mainly consist of a fixed cutter head and a movable cutter head, relying on the relative movement of the two to achieve the shearing of the steel plate. However, in the existing technology, shearing machines often have some problems during operation, affecting their safety, shearing accuracy, and ease of operation.

[0003] Existing steel plate shearing machines lack sufficient safety measures, especially during the shearing process, where operators may be exposed near the moving blades, increasing safety risks. Furthermore, if the steel plate is not adequately secured during shearing, it may shift or warp, affecting not only the accuracy of the shearing but also potentially increasing safety hazards. Many traditional shearing machines, due to design limitations, are typically only suitable for steel plates of a certain size and cannot be quickly adjusted to accommodate steel plates of different widths and thicknesses, resulting in poor flexibility and low production efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a processing protection mechanism for a steel plate shearing machine, which solves the problem that existing steel plate shearing machines lack sufficient protective measures, posing safety risks. During the shearing process, if the steel plate is not adequately fixed, it may shift or warp. Due to design limitations, many traditional shearing machines can usually only adapt to steel plates of a certain specification and cannot be quickly adjusted to adapt to steel plates of different widths and thicknesses, resulting in poor flexibility and low production efficiency during the production process.

[0005] According to one aspect, at least one embodiment of the present invention provides a processing protection mechanism for a steel plate shearing machine, comprising: The protective shell has a first through groove on its top wall for the passage of the movable blade of the shearing machine, a second through groove on its bottom wall for installing the fixed blade of the shearing machine, and material passage grooves through the bottom of the front and rear walls for the passage of steel plates. The protective shell includes two limit frames, which are symmetrically installed on the bottom wall of the inner cavity of the protective shell. The protective shell has through slots on both sides for the limit frames to pass through. The protective shell is equipped with an adjustment mechanism to drive the two limit frames to move, and the outer wall of the protective shell is equipped with a drive mechanism that cooperates with the adjustment mechanism. A clamping assembly, comprising an automatic lifting mechanism and a clamping mechanism, wherein the automatic lifting mechanism is fixed to the top wall of the inner cavity of the protective shell, the bottom movable end of the automatic lifting mechanism is fixedly connected to the top of the clamping mechanism, and the clamping mechanism is installed between two limit frames.

[0006] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of the present invention, the adjustment mechanism includes two parallel bidirectional screws, both of which are rotatably installed between the inner walls of the protective shell, and screw blocks are screwed to both sides of the bidirectional screws, with the screw blocks fixed to the top wall of the corresponding limiting frame.

[0007] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of this utility model, the driving mechanism includes two toothed pulleys. One end of each bidirectional screw passes through the side wall of the protective shell through a bearing and is fixedly connected to the axial position of the corresponding toothed pulley. A matching toothed synchronous belt is installed between the two toothed pulleys. A housing is fixed on the outer wall of the protective shell corresponding to the toothed pulleys and the toothed synchronous belt. A handwheel is installed on the outer wall of the housing. The mounting shaft of the handwheel passes through the side wall of the housing through a bearing and is fixedly connected to the axial position of any one of the toothed pulleys.

[0008] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of this utility model, the automatic lifting mechanism is one of an electric push rod, a pneumatic cylinder, and a hydraulic cylinder.

[0009] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of this utility model, the clamping mechanism includes a sleeve with an open bottom wall. The sleeve is fixed on the movable end at the bottom of the automatic lifting mechanism. Movable rods are slidably installed on both sides of the sleeve. Limiting strips are symmetrically fixed on the inner wall of the sleeve. Limiting grooves that cooperate with the limiting strips are opened on the side walls of the movable rods. The limiting strips are slidably installed in the corresponding limiting grooves. A T-shaped block is fixed at the end of the movable rod outside the sleeve.

[0010] For example, in a processing protection mechanism of a steel plate shearing machine provided in at least one embodiment of the present invention, the side wall of the limiting frame is provided with a T-slot that cooperates with the T-block, and the T-block is slidably installed in the corresponding T-slot.

[0011] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of this utility model, the bottom wall of the sleeve is flush with the bottom wall of the movable rod.

[0012] For example, in a processing protection mechanism for a steel plate shearing machine provided in at least one embodiment of this utility model, the front wall of the protective shell is equipped with an observation window.

[0013] The beneficial effects of the embodiments of this utility model are as follows: (1) In this utility model, the safety of operators is significantly improved by setting a protective shell and a protective structure. During the shearing process, the protective shell effectively isolates the moving blade from the operator, preventing the risk of accidental injury from the blade and ensuring safety during operation. The limit frame design can ensure that the steel plate is accurately positioned during the shearing process, avoiding the deviation of the steel plate, thereby ensuring the accuracy of shearing. Through the adjustment mechanism and the drive mechanism, the spacing of the limit frame can be flexibly adjusted according to the width of the steel plate, so that the device has strong adaptability, can meet the shearing needs of steel plates of different specifications, and expand the application range of the equipment.

[0014] (2) In this utility model, the design of the clamping component can effectively fix the steel plate during the shearing process, preventing it from moving or warping unexpectedly. The setting of the observation window allows the operator to easily observe the shearing process, improving the convenience and safety of operation and reducing potential risks caused by improper operation.

[0022] like Figures 1-2 As shown, it illustrates a processing protection mechanism for a steel plate shearing machine according to an embodiment of the present invention, comprising: The protective shell 1 has a first through groove 2 on its top wall for the passage of the movable blade of the shearing machine, a second through groove 3 on its bottom wall for installing the fixed blade of the shearing machine, and a material passage groove 4 through the bottom of the front and rear walls for the passage of steel plates. There are two limit frames 5, which are symmetrically installed on the bottom wall of the inner cavity of the protective shell 1. The protective shell 1 has through slots on both sides for the limit frames 5 to pass through. The protective shell 1 is equipped with an adjustment mechanism 6 to drive the two limit frames 5 to move. The outer wall of the protective shell 1 is equipped with a drive mechanism 7 that cooperates with the adjustment mechanism 6. The clamping assembly includes an automatic lifting mechanism 8 and a clamping mechanism 9. The automatic lifting mechanism 8 is fixed on the top wall of the inner cavity of the protective shell 1. The bottom movable end of the automatic lifting mechanism 8 is fixedly connected to the top of the clamping mechanism 9. The clamping mechanism 9 is installed between two limit frames 5.

[0023] The front wall of the protective shell 1 is equipped with an observation window 10.

[0024] In this embodiment, the first through slot 2 on the top wall of the protective shell 1 is for the passage of the movable blade of the external shearing machine, and the second through slot 3 is for the installation of the fixed blade of the external shearing machine. After installation, the fixed blade of the external shearing machine is flush with the bottom wall of the inner cavity of the protective shell 1. The material passage trough 4 is used to place the steel plate to be sheared, and the limiting frame 5 is used to guide the rectangular steel plate, ensuring that the steel plate moves between the two limiting frames 5 without deviation, thus ensuring the cutting effect. The driving mechanism 7 can adjust the distance between the two limiting frames 5 through the adjusting mechanism 6 to accommodate steel plates of different widths, making it widely applicable. The clamping assembly is used to clamp and fix the two sides of the steel plate during cutting, which can prevent the steel plate from moving accidentally during the shearing process. The observation window 10 allows the operator to easily observe the shearing process.

[0025] like Figures 2-3 As shown, it illustrates the adjustment mechanism 6 and the drive mechanism 7 in another embodiment of the present invention. The adjustment mechanism 6 includes two parallel bidirectional screws 61, both of which are rotatably mounted between the inner walls of the protective shell 1. Both sides of the bidirectional screws 61 are screwed with screw blocks 62, which are fixed to the top wall of the corresponding limiting frame 5.

[0026] The drive mechanism 7 includes two toothed pulleys 71. One end of the bidirectional screw 61 passes through the side wall of the protective shell 1 through a bearing and is fixedly connected to the axis of the corresponding toothed pulley 71. A matching toothed synchronous belt 72 is installed between the two toothed pulleys 71. A housing 73 is fixed on the outer wall of the protective shell 1 at the positions of the toothed pulleys 71 and the toothed synchronous belt 72. A handwheel 74 is installed on the outer wall of the housing 73. The mounting shaft of the handwheel 74 passes through the side wall of the housing 73 through a bearing and is fixedly connected to the axis of any one of the toothed pulleys 71.

[0027] In this embodiment, the drive mechanism 7 can adjust the distance between the two limiting frames 5 through the adjustment mechanism 6 to accommodate steel plates of different widths, thus having a wide range of applications. When it is necessary to adjust the position of the two limiting frames 5, the handwheel 74 is turned, which drives the toothed pulley 71 at the current position to rotate. At the same time, the toothed synchronous belt 72 drives the toothed pulley 71 on the other side to rotate synchronously, which in turn drives the two bidirectional screws 61 to rotate synchronously. The bidirectional screws 61 drive the two limiting frames 5 to move closer or further apart through the screw block 62, thereby adjusting the position of the limiting frames 5.

[0028] like Figures 3-4 As shown, it illustrates an automatic lifting mechanism 8 and a pressing mechanism 9 in another embodiment of the present invention. The automatic lifting mechanism 8 is one of an electric push rod, a pneumatic cylinder, and a hydraulic cylinder.

[0029] The clamping mechanism 9 includes a sleeve 91 with an open bottom wall. The sleeve 91 is fixed to the movable end of the bottom of the automatic lifting mechanism 8. Movable rods 92 are slidably installed on both sides of the sleeve 91. Limiting strips 94 are symmetrically fixed on the inner wall of the sleeve 91. Limiting grooves 95 that cooperate with the limiting strips 94 are opened on the side wall of the movable rods 92. The limiting strips 94 are slidably installed in the corresponding limiting grooves 95. A T-block 93 is fixed to the end of the movable rods 92 located outside the sleeve 91.

[0030] The side wall of the limiting frame 5 is provided with a T-slot 11 that mates with the T-block 93, and the T-block 93 is slidably installed in the corresponding T-slot 11.

[0031] The bottom wall of sleeve 91 is flush with the bottom wall of movable rod 92.

[0032] In this embodiment, the clamping assembly is used to clamp and fix both sides of the cut steel plate, preventing accidental movement of the steel plate during the shearing process. Simultaneously, the clamping mechanism 9 within the clamping assembly can adjust its length according to the distance between the limiting frames 5. When clamping the steel plate, the automatic lifting mechanism 8 extends, driving the clamping mechanism 9 vertically downwards along the T-slot 11 until the bottom walls of the sleeve 91 and the movable rod 92 press against the top wall of the steel plate, thus fixing the steel plate. The bottom wall of the sleeve 91 is flush with the bottom wall of the movable rod 92, ensuring that both sides of the cut position of the steel plate are fully clamped. Simultaneously, when the limiting frames 5 move, the movable rod 92 can move along the sleeve 91 direction under the action of the limiting strip 94 and the limiting groove 95, ensuring the normal operation of the clamping mechanism 9.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
