Example Embodiment

[0014] The present invention will be further described below in conjunction with the drawings.

[0015] Reference Figure 2~3 The composition of the embodiment includes frame 1, high pressure pipe 2, liquid channel 2-1, ultra-high pressure pump 3, rubber bag 4, liquid filling port 4-1, upper mold 5, lower mold 6, guide post 7, mold opening Combine the cylinder 8, the cylinder support rod 9, the rail 10 and the traveling cylinder 11. Among them, the high-pressure pipe 2, the ultra-high pressure pump 3 and the rubber bag 4 constitute a hydraulic transmission mechanism, which is used to transmit pressure to the processing part of the metal imitation bamboo pipe; the upper mold 5, the lower mold 6, the guide post 7, the mold opening and closing cylinder 8. The cylinder support rod 9, the rail 10, the traveling cylinder 11 and the sliding block constitute a forming mechanism, which is used to process the processing parts of the metal bamboo pipe into the required three-dimensional sh...

Abstract

The invention relates to the technical field of metal punching equipment and particularly relates to a hydraulic bulging machine. An outdoor guardrail made of PVC (Polyvinyl Chloride) plastic has the problems of high ageing possibility, cold brittleness, environmental pollution and the like, and an outdoor guardrail made of metal has the problems of difficulty in molding, long processing period, high processing cost and the like. The invention discloses a hydraulic bulging machine which is high in molding efficiency and safe and reliable in operation and is used for manufacturing a metal outdoor guardrail with bionic appearance. The hydraulic bulging machine is capable of finishing hydraulic bulging processing by use of a super-pressure pump, a rubber bag and a die. The hydraulic bulging machine is simple and compact in design, easy to implement, construct and maintain and low in energy consumption and cost, is applicable to industrial large-batch production of various hollow metal components and has wide application and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of metal stamping equipment, in particular to a hydraulic bulging machine. Background technique [0002] Outdoor guardrails mainly include traffic guardrails, street guardrails, scenic spot guardrails and villa area guardrails, etc., which are generally made of PVC plastic pipes. Outdoor guardrails are exposed to sunlight for a long time, and PVC plastic is prone to aging due to its own material characteristics. According to statistics, in areas with strong sunlight radiation, outdoor guardrails made of PVC plastic pipes generally experience serious aging within 3-5 years and cannot be used any longer. The strength of PVC plastic is low, and its hardness and brittleness are high, especially in the cold winter, the problem of low temperature brittle cracking of PVC plastic is very prominent. In addition, once the PVC plastic is aged or damaged, the problem of pollution to the surrounding environment is also...
