Description

Technical Field

[0001] The utility model relates to the field of metal smelting and rolling product processing, in particular to a fixed-length cutting device for metal smelting and rolling products. Background Art

[0002] The existing patent (publication number: CN217991105U) proposes a fixed-length cutting device for metal smelting rolled products, including a workbench, a control panel is provided on the outer surface of one side of the workbench, U-shaped mounting frames are fixedly installed on the outer surfaces of both sides of the workbench, a hydraulic cylinder is provided on the upper outer surface of the U-shaped mounting frame, a connecting ring is provided on the other end of the piston rod of the hydraulic cylinder, a slider is provided on the lower outer surface of the connecting ring, slide rails are provided between the outer surfaces of both sides of the slider and the U-shaped mounting frame, a replaceable blade device for improving the convenience of blade replacement is provided on the lower outer surface of the slider, and a placement seat is fixedly installed on the upper outer surface of the workbench. However, this device "has two groups of clamping and positioning devices, and the clamping and positioning devices are respectively located at both ends of the U-shaped mounting frame", so that this device only fixes the two ends of the rolled product, so that the rolled product at the edge of the blade is not fixed when the tool is cutting downward, which may cause the rolled product to be deformed by external force, thereby affecting the flatness of the incision. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a device for cutting metal smelting pressed products by driving a tool bearing block downward through a cutting hydraulic cylinder. While the tool bearing block is pressed downward, a No. 1 horizontal displacement slider on both sides is driven to move away from each other through a linkage support rod. The No. 1 horizontal displacement slider pushes the No. 2 horizontal displacement slider to move away from each other. The No. 2 horizontal displacement slider drives an auxiliary pressure block downward through a clamping driving connecting rod to press on the metal rolled product. As the cutting tool continues to move downward, the cutting operation of the metal rolled product is completed, ensuring that the auxiliary pressure block can press the metal rolled product near the incision during the cutting process, ensuring that the metal rolled products on both sides of the incision will not move easily during the subsequent cutting process, and ensuring the integrity of the incision.

[0010] 3. The irregular curved pressure roller of the utility model is pressed tightly on the upper part of the positioning block of the rolled product, so that the operator can drive the pressing driving rod to press down to complete the synchronous pressing of the positioning blocks of the rolled products on both sides, and complete the fixation of the ends of the metal rolled products.

[0011] 4. The utility model traction platform bearing groove is sleeved on the outside of the traction platform bearing slideway, so that the weight of the traction platform, the clamping drive rod, and the rolled product positioning block connector is mainly borne by the traction platform bearing slideway, avoiding excessive wear of the traction drive screw due to excessive load, reducing the failure probability of the traction drive screw, and ensuring the service life of the traction drive screw.
