Description

Technical Field

[0001] This invention relates to an automatic clamping mechanism for assembling and disassembling energetic material molds and barrels, belonging to the field of energetic material extrusion processing. Background Technology

[0002] In the extrusion molding of energetic materials, the reliable engagement and disengagement of the die and barrel is crucial for ensuring the safety and stability of the production process. Energetic materials are flammable and explosive, placing high demands on the precision and reliability of processing equipment. Traditional manual bolt assembly and disassembly methods are not only inefficient and labor-intensive, but also pose a high safety risk due to direct contact with hazardous materials during frequent assembly and disassembly. Furthermore, the poor precision of manual die assembly can easily cause mechanical injuries to operators. Therefore, developing an automatic die and barrel clamping mechanism suitable for energetic material extrusion is of great significance for improving the safety, production efficiency, and product quality of energetic material processing and operator operations. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of poor safety and low efficiency in manually disassembling and assembling the connecting bolts of the mold and barrel during the extrusion processing of energetic materials. It provides an automatic clamping mechanism for disassembling and assembling the mold and barrel of energetic materials. Through the hinge structure and lever drive principle, it can achieve efficient, safe and reliable clamping of the mold and barrel, and can adapt to the operating requirements of the extruder under high working pressure.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] An automatic clamping mechanism for assembling and disassembling energetic material molds and barrels according to the present invention includes a support plate, an opening clamping cylinder fixed in the middle of the support plate, two clamping arm supports symmetrically fixed at both ends of the plate surface of the support plate, two clamping arms connected to the upper ends of the two clamping arm supports by a rotating shaft, a clamping flange fixed to the inner side of the upper end of each clamping arm, and a thrust seat fixed to the front end of the piston rod of the opening clamping cylinder; the two ends of the thrust seat are hinged to the middle of the clamping arm on the same side by a connecting rod.

[0006] The opening cylinder pulls the thrust seat down through the piston rod, and the thrust seat drives the upper ends of the two clamping arms to move relative to each other through the connecting rods hinged at both ends, so that the two clamping flanges clamp the product.

[0007] The opening cylinder pulls the thrust seat upward via the piston rod. The thrust seat drives the upper ends of the two clamping arms to move in opposite directions via connecting rods hinged at both ends, causing the two clamping flanges to loosen the product.

[0008] The inner surface of the clamping flange is machined into a trapezoidal groove or a semi-circular groove structure to improve the reliability of the clamping products.

[0009] Beneficial effects

[0010] The automatic clamping mechanism of this invention achieves automatic and reliable clamping under working pressure through the trapezoidal groove and lever structure of the clamping flange, making clamping and releasing operations safer and more efficient. Furthermore, by adjusting the size and position of the clamping flange, it can meet the clamping requirements of barrels and molds of different sizes. The hydraulic drive system can be adjusted according to different working pressure requirements to ensure the adaptability of the clamping force. In summary, this invention improves the safety, production efficiency, and product quality of energetic material processing and operator operations, and has broad application prospects.

[0015] Example

[0017] The opening cylinder 6 pulls the thrust seat 5 down through the piston rod. The thrust seat 5 drives the upper ends of the two clamping arms 3 to move relative to each other through the connecting rod 2 hinged at both ends, so that the two clamping flanges 4 clamp the product.

[0018] The opening cylinder 6 pulls the thrust seat 5 upward through the piston rod. The thrust seat 5 drives the upper ends of the two clamping arms 3 to move in the opposite direction through the connecting rod 2 hinged at both ends, so that the two clamping flanges 4 loosen the product.

[0019] like Figure 2As shown, the inner surface of the clamping flange 4 is machined into a trapezoidal groove structure to improve the reliability of the clamping product.
