  • Publication number: 20170173709
    Abstract: A hydraulic rolling-cut shears, including: a horizontally disposed hydraulic cylinder; a shear mechanism including an upper tool post and a lower tool post; a linkage mechanism including a first upper connecting rod, a first lower connecting rod, a second upper connecting rod, a second lower connecting rod, and a synchronous connecting rod; and supports including a hydraulic cylinder support and a guiding rod support. The hydraulic cylinder is hinged to and disposed on the hydraulic cylinder support through a first pin. One end of the first upper connecting rod, one end of the first lower connecting rod, and one end of the synchronous connecting rod are hinged to one end of a piston rod of the hydraulic cylinder via a second pin. The first upper connecting rod, the synchronous connecting rod, and the first lower connecting rod are disposed at one side of the hydraulic cylinder support.

  • Patent number: 9593805
    Abstract: A liquid distributing valve includes a housing, an oil supply passage, an oil storage valve and a two-position three-way valve. The oil storage valve is separated into an oil storage chamber and an oil pressing chamber by a piston, and the oil storage chamber is in communication with an oil discharge port and has a spring pressing against the piston. The two-position three-way valve includes a valve body cavity having an oil inlet in communication with the oil supply passage, a valve core and a valve seat having a core hole in communication with the oil storage chamber via a bypass oil passage. When the valve core is at one position, the oil inlet is blocked off, and the oil pressing chamber is in communication with the oil storage chamber. When the valve core is at another position, the core hole is blocked off, lubricant enters the oil inlet.

  • Publication number: 20160271674
    Abstract: A method for preparing a metal composite plate/strip by rolling, comprises the following steps: 1) respectively rolling the composite surfaces of a base plate and a cladding plate to obtain the base plate corrugation and the cladding plate corrugation for mating with each other; 2) cleaning the composite surfaces of the base plate and the cladding plate to expose the metal matrixes; 3) sequentially laminating the base plate and the cladding plate so that the base plate corrugation on the base plate and cladding plate corrugation on the cladding plate mate with each other, compacting, and performing welding sealing treatment to obtain a composite plate slab; 4) rolling the qualified composite plate after inspection by using a compositing machine to a desirable thickness, to obtain a composite plate/strip.

  • Publication number: 20160271664
    Abstract: The present invention discloses a method for rolling a metal composite plate/strip, comprising the following steps: 1) selecting a metal base plate and a metal cladding plate, cleaning the surfaces of the base plate and the cladding plate to be composited until the metal matrixes are exposed; 2) sequentially laminating the base plate and the cladding plate to obtain a composite plate slab; 3) rolling the composite plate slab through a composite rough rolling mill having a corrugated roll to obtain a composite plate having a corrugated mating surface on its composite surface; and 4) flattening the composite plate having a complete corrugated cladding plate by a composite finish rolling mill to a desirable thickness to obtain a composite plate/strip.
