Description

Technical Field

[0001] This utility model relates to the technical field of steel structure processing equipment, and in particular to a cold-cutting steel structure processing machine tool. Background Technology

[0002] Cold-cutting steel structure processing machine tools are a type of specialized equipment that uses mechanical force to cut, bevele, and finish steel structure materials at room temperature. Their core feature is avoiding the high-temperature heat-affected zone generated by flame cutting and ion cutting, effectively reducing thermal deformation, oxide layer formation, and mechanical property damage in steel components. Therefore, they are widely used in fields requiring high processing precision and workpiece integrity. These machine tools typically include cold shear machines, cold-cutting flying saws, CNC milling machines, and hydraulic cold-cutting beveling machines. They use a motor-driven transmission system to move the cutting tool or saw blade, and in conjunction with a workpiece clamping mechanism, achieve cold processing of steel structures of various shapes, including profiles, plates, and pipes. They are key equipment for the modern steel structure manufacturing industry's transformation from extensive hot processing to precision cold processing.

[0003] As the demand for steel structure processing upgrades towards high capacity and high consistency, early cold-cut steel structure processing machine tools have gradually revealed their technical limitations. Early equipment mostly consisted of a manual spiral clamping mechanism and a single-axis cutting unit. This not only required frequent manual adjustments to the workpiece position, but also lacked effective auxiliary processing devices during the cutting process. Iron chips accumulated directly on the worktable and guide rail gaps, causing transmission components to jam. Cutting fluid was discharged directly as a single cooling medium, wasting resources and polluting the working environment. The manual cleaning of iron chips required machine shutdown, which restricted processing efficiency. To solve the above problems, existing cold-cut steel structure processing machine tools generally integrate roller conveyor automatic feeding mechanisms. The automatic feeding mechanism uses a servo motor to drive rollers to synchronously transport workpieces, reducing manual intervention. However, the existing structure still has significant shortcomings. Iron chip collection depends on manual periodic cleaning of the filter screen in the collection tank. The cleaning process requires stopping the cutting fluid circulation, resulting in frequent machine shutdowns. In addition, the collected iron chips contain a large amount of cutting fluid, which needs to be dried and separated before recycling. The operation is cumbersome and the cutting fluid utilization rate is low. Utility Model Content

T-shaped block 9 is slidably connected to the inner wall of T-shaped groove 16. T-shaped block 9 is used to enhance the stability of the connection between clamping block 2 15 and gantry 5 or other components, and to prevent clamping block 2 15 from loosening or deviating during sliding.

[0044] Specifically, the scrap collection cart 12 installed at the front of the separation box 301 collects the scrap and impurities that clog the filter screen 302 and are removed from the separation box 301, facilitating subsequent unified processing and recycling. Rollers 13 are rotatably connected around the bottom of the scrap collection cart 12 to reduce friction between the cart and the ground, making it easier for operators to push the cart and transfer scrap. A clamping block 14 is fixedly connected to the top of the inner wall of the gantry frame 5, providing installation support and sliding guidance for the clamping block 15 that slides along the inner wall. To ensure stable movement of clamping block 2 15, clamping block 2 15, together with clamping block 1 14, assists in fixing the relevant components of conveying assembly 8, improving the stability of conveying assembly 8 during operation. The T-shaped groove 16 opened at the bottom of clamping block 2 15 provides a sliding track for T-shaped block 9 that is slidably connected to the inner wall and restricts the displacement direction of T-shaped block 9, preventing T-shaped block 9 from deviating when sliding. T-shaped block 9 enhances the stability of the connection between clamping block 2 15 and gantry 5 or other components, avoiding loosening or deviation of clamping block 2 15 during sliding.

[0045] Working principle: When the machine tool starts cutting large steel, a large amount of iron filings generated by the circular saw are generated simultaneously with the cutting action. At the same time, the spray pipe 804 continuously sprays cutting fluid into the cutting area to cool the circular saw and ensure cutting accuracy, washing and peeling the iron filings off the cutting surface. Under the action of gravity and the gap between the feed table 1, the waste cutting fluid mixed with iron filings falls downwards and falls precisely into the separation mechanism 2 below. It first contacts the inclined screen 201 inside the separation mechanism 2. The separation mechanism 2 achieves active screening through linkage transmission. The motor 210 drives the gear 1 208 to rotate. Because the gear 1 208 meshes with the gear 2 209, the power is transmitted sequentially to the transmission shaft 1 207 and the rotating block 206, causing the rotating block 206 to rotate synchronously. The rotating block 206 then drives multiple flexible plates 2 through the connecting plate 205. 03 reciprocating motion, while the two ends of the flexible sheet 203 are fixed to the screen 201 and the inclined plate 212 by the first fixed block 202 and the second fixed block 204 respectively. The rigid constraint of the flexible sheet 203 ensures that the screen 201 and the inclined plate 212 only shake and do not move up and down. During this process, the inclined screen 201 retains the iron filings in the mixture by continuous shaking. Large iron filings are directly screened out, and small iron filings are also prevented from clogging the screen holes due to shaking. Finally, all the retained iron filings slide into the L-shaped bracket 10 along the inclined surface of the screen 201 for centralized recycling. The filtered cutting fluid passes through the screen 201 and falls to the lower inclined plate 212, flows along the inclined surface to the cutting fluid collection port 213, and flows into the cutting fluid collection tank 214 for temporary storage. Then it is transported to the purification mechanism 3 for deep treatment through the fourth conveying pipe 807.

[0046] Furthermore, the cutting fluid, after initial filtration by the separation mechanism 2, is temporarily stored in clamping block 15 and then pumped into the separation tank 301 of the purification mechanism 3 through conveying pipe 807. The filter screen 302 inside the separation tank 301 performs secondary deep filtration on the cutting fluid, accurately trapping fine iron filings and impurities missed in the initial filtration. The purified cutting fluid enters the conveying pipe 805 of the gantry 5 through conveying pipe 806, and is then conveyed to the spray pipe 804 through conveying pipe 802 and sliding block 803, where it is reused for cooling the cutting area and washing away iron filings, forming a complete cycle and ensuring cleanliness. To ensure efficient cooling and stable circulation, the separator 301 is equipped with an intelligent monitoring and sealing system. When the filter 302 becomes clogged with impurities, increasing the flow resistance, the internal pressure sensor 303 detects the pressure change in real time and triggers the alarm 304 to issue a warning, reminding the user to replace the filter in time to avoid affecting the quality of the cutting fluid due to filter failure. At the same time, the sealing groove 3084 on the top of the separator 301 and the sealing strip 3083 at the bottom of the matching component fit tightly together, and with the pressing action of the two external rollers 305, a tight sealing environment is formed to ensure stable air pressure inside the chamber.
