Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically a pipe clamp stamping die. Background Technology

[0002] Pipe clamps are a fundamental yet crucial component for fixing and supporting pipelines, widely used in pipeline systems across numerous fields such as petrochemicals, power, shipbuilding, construction, and municipal engineering. Their core function is to reliably fix, guide, support, or suspend pipelines to various structures (such as walls, ceilings, and supports), and manage pipeline displacement and stress caused by thermal expansion and contraction, internal pressure, external loads, and vibration.

[0003] Traditional upper punches are typically fixed directly to the upper die base with multiple bolts. Replacement requires tightening or loosening each bolt individually, a time-consuming and labor-intensive operation that severely impacts production continuity and increases equipment setup time. Lower dies are usually single and fixed. When producing pipe clamps of different specifications (such as different curvatures or dimensions), the entire lower die must be disassembled and replaced with a separate complete set. This process is equally time-consuming and requires storing and managing multiple complete sets of dies, resulting in high costs and large footprints. During continuous high-speed stamping, the die generates a significant amount of heat due to intense friction and plastic deformation with the material. Traditional dies often rely on natural air cooling or simple fan cooling, which has low heat dissipation efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipe clamp stamping die includes a housing, a lower die base fixedly connected to the top of the housing, an upper die base provided on the top of the lower die base, an upper convex plate quick-release limiting assembly fixedly connected to the bottom of the upper die base, a lower concave plate switching assembly fixedly connected to the top of the lower die base, and a water cooling assembly provided on the surface of the housing.

[0007] The upper convex plate quick-release limiting assembly includes a mounting plate fixedly connected to the bottom of the upper mold base. The surface of the mounting plate is provided with two through slots. Each of the two through slots has a sliding groove inside. A slider is slidably connected to the inside of each of the two sliding grooves. An L-shaped connecting rod is fixedly connected to the surface of each of the two sliders. The shorter side of each of the two L-shaped connecting rods is slidably connected to the inside of the through slot. A limiting sleeve is fixedly connected to the longer side of each of the two L-shaped connecting rods. The inside of the mounting plate is provided with a T-shaped sliding groove. A T-shaped slider is slidably connected inside the T-shaped sliding groove. A semi-circular punch is fixedly connected to the bottom of the T-shaped slider.

[0008] Furthermore, the concave plate switching assembly includes a housing fixedly connected to the top of the lower mold base. A threaded rod is rotatably connected inside the housing. The right side surface of the threaded rod penetrates the right side of the housing and extends to the outside of the housing. A connecting plate is fixedly connected to the side of the threaded rod surface located outside the housing. Three concave molds are threadedly connected to the surface of the threaded rod.

[0009] Furthermore, a square through groove is provided in the middle of the housing, and the semi-circular punch is located at the top of the concave mold.

[0010] Furthermore, the water-cooling assembly includes a circulation pump fixedly connected to the outer wall of the housing, an inlet pipe fixedly connected to the inlet of the circulation pump, the surface of the inlet pipe penetrating the outer wall of the housing and extending into the interior of the housing, an outlet pipe fixedly connected to the outlet of the circulation pump, and a return pipe penetrating the right side of the housing.

[0011] Furthermore, the lower mold base is provided with a first serpentine tube inside. The left side of the first serpentine tube extends to the outside of the lower mold base and communicates with the water outlet pipe, and the right side of the first serpentine tube extends to the outside of the lower mold base and communicates with the surface of the water return pipe.

[0012] Furthermore, the upper mold base is provided with a second serpentine tube inside. The left side of the second serpentine tube extends to the outside of the upper mold base and is fixedly connected to a water inlet hose. The surface of the water inlet hose is fixedly connected to the water outlet of the water outlet pipe. The right side of the second serpentine tube extends to the outside of the upper mold base and is fixedly connected to a water return hose. The surface of the water return hose is fixedly connected to the water inlet of the water return pipe.

[0013] Furthermore, four limiting telescopic rods are fixedly connected to the top of the lower mold base, and the tops of the four limiting telescopic rods are fixedly connected to the bottom of the upper mold base. The four limiting telescopic rods are distributed in a rectangular shape.

[0014] Furthermore, two hinges are fixedly connected to the surface of the box, and a box door is fixedly connected to the surface of the two hinges.

This pipe clamp stamping die features a quick-release upper punch limit assembly with a sliding block, L-shaped connecting rod, and limit sleeve, enabling rapid installation and removal of the semi-circular punch, significantly reducing die change and adjustment time. The multi-station switching lower concave plate switching assembly uses a threaded rod to drive multiple concave dies, allowing for the stamping of different specifications of pipe clamps on the same die set without requiring a complete die replacement. The water-cooling assembly circulates cooling to the lower and upper die sets via first and second serpentine tubes, effectively dissipating heat generated during stamping and extending the die's service life.

[0017] 2. This pipe clamp stamping die solves the problem of time-consuming and labor-intensive operation that required tightening or loosening bolts one by one during replacement by using the upper convex plate quick-release limiting component. The lower concave plate switching component eliminates the need to disassemble the entire lower die. The water-cooling component solves the problem of excessive heat generated by intense friction and plastic deformation of the material. Attached Figure Description
