Description

Technical Field

[0001] This utility model relates to the field of shearing machines, and in particular to a flat steel shearing machine. Background Technology

[0002] A flat steel shearing machine is a mechanical device used for cutting flat steel materials. It is widely used in metal processing, construction, shipbuilding, and machinery manufacturing industries. Flat steel shearing machines can precisely cut flat steel of different thicknesses and widths to meet various engineering and manufacturing needs. This equipment is usually equipped with an automatic feeding system, which can improve shearing efficiency and accuracy. The shearing methods of flat steel shearing machines include flat shearing and oblique shearing; users can choose the appropriate shearing method according to their actual needs. In addition, flat steel shearing machines are characterized by simple operation, convenient maintenance, and safety and reliability.

[0003] In actual use, flat steel shearing machines often experience issues when the flat steel bars vary in length, causing the tail end to curl up during the shearing process. This can affect shearing accuracy. Specifically, when shearing shorter flat steel bars, insufficient material support can cause the tail end to curl up, resulting in a misalignment between the shearing line and the intended shearing line, thus impacting the shearing quality. This curling not only reduces shearing accuracy but can also cause additional wear and tear on the equipment, shortening its lifespan. Utility Model Content

[0004] The main objective of this invention is to provide a flat steel shearing machine that can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flat steel shearing machine includes a support table, a drive unit, a reducer, a transmission gear assembly, a first transmission component, and a second transmission component. The reducer is installed at the output end of the drive unit, the transmission gear assembly is connected to the output end of the reducer, and the first transmission component and the second transmission component are respectively installed at both ends of the front support of the transmission gear assembly.

[0007] A shearing table is installed on the upper end of the support table. A lifting device is installed on the support table and the shearing table, and the lifting device is connected to the second transmission component. A clamping block is installed on the lifting device. When the second transmission component moves, it drives the clamping block to rise and fall. A through slot is opened on the support table and the shearing table. The first transmission component passes through the through slot and is connected to the shearing component. The other end of the shearing component is fixed to the shearing table through a rotating shaft. The clamping block abuts against the flat steel and the shearing component performs the shearing operation on the flat steel.

[0008] A limiting frame is installed at the other end of the shearing table, and multiple mounting holes are installed at the upper end of the limiting frame. A fixing frame is installed at each mounting hole, and a telescopic device is installed at the upper end of the fixing frame. The telescopic end of the telescopic device is connected to a tail end abutment. The telescopic device drives the tail end abutment to stabilize it against the tail of the flat steel, preventing the tail end from curling up during shearing.

[0009] The outermost end of the limiting frame is provided with multiple rollers, the upper end of the rollers is flush with the shearing table, and the flat steel is driven to the shearing assembly by the rollers. A bearing device is provided at the connection between the rollers and the limiting frame.

[0010] The support table and shearing table are designed in parallel, with support blocks at their four corners. The support table, shearing table, and support blocks are fixed by bolts. The limiting frame is fixed to the shearing table by bolts. The round rod of the lifting device passes through the support table and shearing table.

[0011] The first and second transmission components are connected to the transmission gear assembly via a transmission shaft. The abutting block is installed in the middle of the lifting device, and the lower end of the abutting block is connected to an anti-slip rubber pad by an adhesive.

[0012] The mounting holes are evenly distributed on the limiting frame. The lower end of the fixing frame is provided with screw holes, and bolts are inserted to fix it on the limiting frame. The fixing frame is adjusted on the limiting frame through the mounting holes, thereby adjusting the distance between the shearing component and the tail end abutment.

[0013] The fixed frame is designed in an inverted "U" shape, and the telescopic device is fixed to the fixed frame by bolts. The telescopic device is a hydraulic cylinder or an electric push rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Thanks to a precise lifting device and efficient shearing components, we can achieve rapid and accurate shearing of flat steel materials, significantly improving work efficiency. Through a series of simple and convenient adjustments and operating procedures, users can easily set the shearing height and gap to accommodate the shearing needs of flat steel materials of various thicknesses and lengths. This automated operation of the lifting device and shearing components greatly reduces the need for manual intervention, thereby lowering the risks during operation.

[0016] Specially designed clamping blocks and tail clamping seats stably secure the flat steel material, ensuring it doesn't warp or move unnecessarily during shearing, thus effectively reducing potential material damage. Furthermore, the equipment is designed for ease of maintenance and adjustment. Using bolted connections and an adjustable mounting bracket, users can easily adjust the shearing gap and position, improving efficiency and extending the equipment's lifespan. Precise shearing operations significantly reduce material waste, thereby increasing material utilization. Attached Figure Description

Install the lifting device 8 on the support table 1 and the shearing table 10, ensuring it is connected to the second transmission component 7. Install the abutment block 9 on the lifting device 8. Create through slots on the support table 1 and the shearing table 10. Connect the first transmission component 5 through the through slot to the shearing assembly 6. Secure the other end of the shearing assembly 6 to the shearing table 10 via a rotating shaft. Install the limiting frame 11 at the other end of the shearing table 10.

Adjust the position of the fixing frame 14 to set the distance between the shearing assembly 6 and the tail end abutment 16. Place the flat steel on the roller 12, ensuring it is straight. Move the flat steel to the shearing assembly 6 via the roller 12. A drive motor can be installed at the roller 12 to rotate the roller 12, or the flat steel can be manually pushed to feed it into the shearing assembly 6. Start the lifting device 8 to lower the abutment block 9 and hold the flat steel in place. Start the shearing assembly 6 to perform the shearing operation. After shearing is completed, the lifting device 8 drives the abutment block 9 to rise and release the flat steel. Check the shearing effect to ensure there are no burrs or unevenness. Clean the shearing area to ensure the equipment is clean.

[0033] Adjustment Process: Adjust the lifting device 8 according to the thickness of the material to be sheared to set a suitable shearing height. Ensure the distance between the shearing assembly 6 and the clamping block 9 is appropriate to guarantee the shearing effect. Adjust the rotation shaft of the shearing assembly 6 to set a suitable shearing gap. Ensure the shearing gap is uniform to avoid uneven shearing force during shearing. Adjust the position of the fixing frame 14 on the limiting frame 11 according to the required length of flat steel to be sheared. Ensure that the tail end clamping seat 16 can stably abut against the tail of the flat steel to prevent the tail end from curling up during shearing. Regularly check the tightness of all connecting parts and transmission parts. Clean and lubricate the transmission parts to ensure smooth operation of the equipment.
