This invention discloses a drilling device for processing and producing wrought iron railings, relating to the field of wrought iron railing processing technology. It includes a support leg, a drilling mechanism, and a fourth transmission rail. The drilling mechanism is located on the top of the support leg, and the fourth transmission rail is installed on the top of the support leg. The drilling mechanism includes multiple positioning frames that slide on the top of the fourth transmission rail. Each positioning frame has a railing placement groove on its top to ensure the holes are at the same horizontal position. After drilling, the railings are directly welded and fixed, ensuring that the holes of the connecting pieces align with the connecting posts during subsequent bolt connections. This improves installation quality and avoids enlarged holes and misalignment of the railings after installation. This process ensures that the holes of the connecting pieces and connecting posts correspond perfectly, improving hole accuracy. Direct welding after drilling reduces process steps, increases processing efficiency, and ensures overall structural dimensional stability.

The invention provides brake pad back plate blank stamping equipment, and relates to the technical field of brake pad back plate production. The brake pad back plate blank stamping equipment comprises a stamping machine and a material conveying platform, the material conveying platform is arranged at the position of a feeding port of the stamping machine, the brake pad back plate blank stamping equipment further comprises a die discharging table, and the die discharging table is fixedly arranged at the lower end of the inner side of a shell of the stamping machine. The discharging mechanism achieves rapid interception and discharging of waste through pushing blocks with different heights, and clamping stagnation caused by adhesion of the waste to a mold and a formed blank is avoided. The outlet is formed in the die blanking table, so that the back plate can quickly fall down and be taken out after being processed, the production efficiency is improved, the potential safety hazard of manual operation is eliminated, and the effect of quickly and automatically discharging waste materials and processed parts is achieved; the problems that waste materials and workpieces need to be manually taken out of the die after stamping, efficiency is low, and potential safety hazards exist are solved.

This invention discloses a laser drilling device, comprising a feeding mechanism, a laser drilling mechanism, and a discharging mechanism arranged sequentially. The laser drilling mechanism includes a dual-axis moving platform, a vacuum positioning stage mounted on the dual-axis moving platform, and a laser unit positioned above the dual-axis moving platform. The dual-axis moving platform can drive the vacuum positioning stage to move along a first direction or a second direction. The laser unit has at least two spaced-apart laser emitters. The vacuum positioning stage is equipped with at least one set of stage assemblies, each set of stage assemblies having two material adsorption plates and a positioning component. The positioning component positions the material pieces on the two material adsorption plates, ensuring that the distance between the material pieces on the two material adsorption plates is the same as the distance between the two laser emitters. Without increasing the positioning time, this device effectively improves drilling efficiency while ensuring drilling accuracy.

This utility model relates to the field of steel pipe processing technology, specifically to an integrated punching and drawing device for steel pipes. It includes a worktable with a clamping assembly fixedly installed in the middle. The clamping assembly includes a first cylinder, which is fixedly installed at the lower end of the middle position of the worktable. A base plate is fixedly connected to the first cylinder, and a fixing plate is fixedly connected to the upper end of the first cylinder. Fixing rods are fixedly connected to both the front and rear sides of the upper end of the base plate, and first connecting rods are sleeved on both the left and right ends of the fixing rods. A second connecting rod is connected to the middle position of the first connecting rod. During punching, a third cylinder drives the puncher downwards, while the second cylinder drives a robotic arm to apply axial tension to the steel pipe, balancing the punching force and preventing the thin-walled steel pipe from collapsing or the hole edge from deforming. The drawing action reduces material elastic rebound and burr generation, ensuring smooth hole walls and precise hole shapes.

This invention discloses a drone-mounted fire-fighting projectile pod, belonging to the field of drone fire-fighting equipment technology, aiming to solve the problems of insufficient transportation stability, deployment safety, and accuracy when fire-fighting projectiles are used in conjunction with drones. The pod includes a main structure, a projectile connector, a suspension and deployment system, sensing and control components, a safety valve, an altitude-holding device, and an interface structure. The main structure adopts an aerospace-grade aluminum alloy unibody design, adaptable to various specifications of fire-fighting projectiles such as 2.5KG, 10KG, and 20KG. The suspension and deployment system adopts a motor-driven gear and gear-driven rack design, all integrated into one unit. The sensing and control components include a Hall sensor, a control circuit board, and a manual projectile mounting switch. The safety valve has a mechanical pin-type safety structure. The altitude-holding device uses millimeter-wave scanning radar. The interface structure has multiple reserved ports and a standardized design. This invention achieves reliable control of the entire process of fire-fighting projectile transportation, mounting, and deployment, with strong adaptability and high safety, and can be widely used in drone fire-fighting operations.

This invention relates to the field of building construction, and more particularly to a construction device for pre-embedded components in building walls. The device, as described in this invention, features a vertical guide rail on a lifting frame with vertical rods. These rods are first electromagnetically attached to pre-embedded plates already installed in the wall using an electromagnet. The lifting frame then lowers the worker to the lower installation position to install the next set of pre-embedded plates and pre-embedded screws. The lifting frame is not easily affected by crosswinds, thus preventing slight swaying. This invention solves the technical problem of swaying caused by crosswinds when workers are drilling and installing pre-embedded components on walls, which affects the worker's operational accuracy and construction efficiency.
