The upper main oil cylinder is arranged at the upper part of the upper box body, and theupper sliding blocks are arranged at the lower part of the upper box body; the upper molds are fixed at the bottom of the upper sliding blocks, and a driving unit is arranged between the upper main oil cylinder and the upper sliding blocks; the upper main oil cylinder drives the upper sliding blocks to move in a vertical direction through the driving unit; and the lower sliding blocks are arranged in the lower box body, the lower portions of the lower sliding blocks are connected with the lower main oil cylinders, the upper portions of the lower sliding blocks are connected with the lower molds, and the lower main oil cylinders drive the lower sliding blocks to move in the vertical direction. The low-cost container top plate hydraulic forming system relates to a special machine designed for a container top plate structure, the cost of equipment purchasing is greatly reduced, and the economic burden of a small-and-medium-sized container top plate production enterprise is reduced.

The invention discloses a trench steel cover plate component, which comprises a corner protector and a cover plate which is arranged on the corner protector and is characterized in that: the corner protector is a sunk corner protector; the sinking height of the corner protector is equivalent to the thickness of the cover plate; the corner protector is a group of angle irons which are respectively fixed on the trench surface and the subsidence surface; the cover plate comprises two supports which are arranged on the corner protector, two ribbon strips which are connected with the supports, and a top plate which is fixed on the supports and the ribbon strips; the top plate is provided with a key hole the lower part of which is provided with a collection box; a drainage hole is arranged on the collection box; and the collection box is movably connected with the top plate or a bottom plate or a side plate of the collection plate is detachably connected with other parts at the bottom of the collection box. The trench steel cover plate component can guarantee that the cover plate is parallel to the ground, has good bending rigidity, flexural capacity and surface evenness, and has low steel amount. Moreover, the cover plate is convenient to open and reset, and dust and small sundries falling from the key hole can be collected.

The invention discloses a blind wave top plate manufacturing method capable of reducing machining cost, and belongs to the technical field of blind wave top plate manufacturing. The blind wave top plate manufacturing method comprises the manufacturing steps that 1, a continuous coil steel is uncoiled, and is discharged to be a steel plate of a certain length; 2, the to-be-moulded steel plate is placed on an edge pressing ring on a worktable; 3, a piston of an upper main oil cylinder moves horizontally, and two vertical connection rods drive an upper mould to move downwards to closely press theto-be-moulded steel plate; 4, a lower mould is driven to move vertically by a lower main oil cylinder, and a blind wave is formed on the to-be-moulded steel plate in one step; 5, motors drive lead screws to rotate; slide bases sleeving the two lead screws move horizontally, and a baffle finger drives the steel plate to move to be subjected to moulding operation of a next blind wave; and 6, the moulded steel plate is subjected to positioning and trimming treatment sequentially. According to the manufacturing technique provided by the invention, the special machine designed for the blind wave top plate structure is used; equipment purchasing cost is greatly reduced; and financial load of middle and small container top plate manufacturing enterprises is alleviated.

The invention discloses a mobile terminal, which comprises a shell and a touch screen, wherein at least one boss for inserting the shell is arranged at one end of the touch screen; and the other end of the touch screen is stuck to the shell. By the mobile terminal, under the condition that the touch screen is not lifted, the sticking area is reduced, and the detachability of the touch screen is improved.

The invention discloses a roller-type fed material bagging machine which is provided with a rack and a roller. A bag feeding device and a heat sealing device are arranged on the outer side of the roller. Work grooves are evenly formed in the rollers. A bag propping mechanism is arranged at a feeding position of a material bagging machine and is provided with a bag propping frame. U-shaped bag propping rods are arranged on the two sides of the bag propping frame. Bag opening mechanisms are arranged at the work grooves. The roller-type fed material bagging machine is characterized in that packaging bag tensioning mechanisms are arranged on one sides of the U-shaped bag propping rods; a bag rubbing mechanism is arranged above the work grooves; and bag grabbing and pulling mechanisms are arranged at discharge outlets of the work grooves. By adoption of the bagging machine, tensioning of a bag opening during material feeding of a packaging bag is achieved, tilting-up or wrinkling of the two edges of the packaging bag is avoided, the two walls of the packaging bag can be rubbed open when the bag needs to be opened, and the bag opening effect is guaranteed; and before heat sealing, the bag opening of the packaging bag is pulled to be level, so that the bag opening after heat sealing is flat, and a good packaging effect is achieved.
