The invention discloses a novel process for manufacturing leather shoes, which comprises the steps of lasting, napping, adhesive brushing, rubber sheet placement in a die cavity, injection molding and vulcanization molding, wherein before the step of lasting, a rubber sheet and a vamp are stitched together by using a stitching thread, and then the steps of lasting, napping, adhesive brushing, rubber sheet placement in a die cavity, injection molding and vulcanization molding are performed. Compared with traditional mould pressing modes, the process disclosed by the invention has the differences that after the step of adhesive brushing is completed, rubber and the vamp are stitched together by using a stitching thread, then the steps of adhesive brushing and vulcanization are performed, the rubber subjected to vulcanization in the die cavity and the rubber of the original stitching thread are fused into a whole, and then through the adhering action of an adhesive, the strength of the stitching thread is increased, therefore, the adhering strength of the vamp and a rubber sole is greatly improved, and through measuring and calculating, the adhering strength can be increased by more than one time. Meanwhile, the appearance quality of products has no change, and the stitching thread can not be seen from the vamp and inside of a shoe, but a stitching thread is just added in the internal structure of the shoe.

The invention discloses an ultra-light amorphous reinforced carbon fiber table tennis bat. The table tennis bat comprises a core plate, a carbon fiber layer and an amorphous alloy layer, wherein the core plate is mainly made of a foaming material; wherein the carbon fiber layer is coated outside the core plate; and the amorphous alloy layer is coated outside the carbon fiber layer. The surface ofthe table tennis bat is provided with a plurality of layers of amorphous alloy thin strips, the table tennis bat has the advantages of being high in elastic energy storage and moderate in modulus, thebat bottom plate can rapidly generate corresponding deformation during low impact, ball control is facilitated, and the defects that the ball control performance is poor and the hand feeling is poordue to the fact that the rigidity of a carbon fiber table tennis bat is too large are thoroughly overcome; and when the table tennis ball is subjected to large impact, the amorphous alloy has high-elasticity stored energy, so that the strength can be more effectively transmitted to the table tennis ball through a rubber sheet, the ball hitting efficiency is improved by over 30 percent, and the table tennis ball is particularly suitable for attacking methods such as loop balls and the like.

The invention provides a preparation method of a high-strength tire curing bladder, and relates to the technical field of tire curing bladder production and processing. In a component of the tire curing bladder, raw rubber comprises butyl rubber and brominated butyl rubber; a filler comprises carbon black, acetylene carbon black, graphite and aluminum oxide; an active agent is zinc oxide master batch particles; a processing aid comprises stearic acid and paraffin; a vulcanizing agent comprises vulcanized resin and sulfur; wherein the unsaturation degree of the butyl rubber is 0.5-2%, and the brominated butyl rubber contains 1.5-2.5% of bromine. The preparation method comprises following steps: carrying out three-stage rubber mixing to process a rubber sheet, and then injecting and vulcanizing to obtain the tire curing bladder. Compared with the prior art, the invention has the advantages that the butyl rubber and the brominated butyl rubber are used as raw rubber, and an adopted rubberextruder is three-stage rubber mixing equipment, so that high-temperature mixing time is shortened, the stability of the brominated butyl rubber is maintained, the purpose of uniform mixing is achieved, and the vulcanization time can be shortened while the strength is improved.

The universal wind power generation device comprises a fan blade rotating part, the fan blade rotating part comprises a rotating shaft and a metal frame, the rotating shaft is evenly provided with a plurality of arc-shaped blades, and the arc-shaped blades are fixedly connected with the rotating shaft; and one end of the rotating shaft is provided with a transmission connecting piece. The number of the arc-shaped blades is four, each arc-shaped blade is of a double-layer structure and comprises a metal net blade and a soft rubber layer, the soft rubber layers are located on the concave face sides of the arc-shaped blades, and the metal net blades are located on the convex face sides of the arc-shaped blades. The soft rubber layer comprises a plurality of soft rubber pieces which are evenly distributed, the soft rubber pieces are rotationally connected with the metal net blades, and the transmission connecting piece is used for being connected with a generator. The arc-shaped blades with the windward concave surfaces can be pushed by wind power to rotate, and the soft rubber sheets on the arc-shaped blades with the windward convex surfaces can be opened to play a role in filtering wind power, so that the thrust obtained by the concave surfaces is always greater than the thrust obtained by the convex surfaces regardless of the wind direction in any direction, and the four arc-shaped blades can keep rotating in one direction.

The invention discloses a new energy automobile bottom protection plate and relates to the technical field of automobile bottom protection plates. The new energy automobile bottom protection plate comprises a main body and a placement assembly. Reinforcing plates are fixed to the two sides of the main body, mounting holes are formed in the surfaces of the reinforcing plates, elastic connecting ropes are arranged outside the mounting holes, and the other ends of the elastic connecting ropes are connected with plugs; a rubber sheet is connected to the top of the plug, cross-shaped patterns are formed in the surface of the rubber sheet, a blocking sheet is installed on the upper portion of the main body, and a heat dissipation opening is formed in the surface of the main body. According to the new energy automobile bottom protection plate, through mutual matching arrangement of the main body inner side fixing block, the lantern ring, the tough belt and the breathable plate, the breathable plate can be tightened and straightened through the tough belt, so that the breathable plate of a flexible structure can be attached to the outer surface of an engine, the vibration generated when the engine works can be reduced. Noise generated in the working process of the engine is effectively reduced, the ventilation plate has good ventilation performance, and therefore heat dissipation of the engine cannot be affected.

The invention relates to the technical field of rubber shock absorption, and discloses a hoisting crane supporting leg rubber shock absorber for preventing a construction ground from being damaged. The rubber shock absorber comprises a movable supporting leg, wherein a lifting oil cylinder is fixedly mounted at the lower left end of the movable supporting leg, a connecting rod is fixedly mounted at the lower end of the lifting oil cylinder, a top cover plate is fixedly mounted at the lower end of the connecting rod by means of a fixing base, threaded holes which are evenly distributed are formed in the top cover plate, a stabilizing rod is fixedly mounted at the lower end of the top cover plate, and the stabilizing rod can be fixed in a movable groove by means of a limiting block to move up and down. According to the rubber shock absorber, the surfaces of the stabilizing rod and a stabilizing rod base are sleeved with springs, when balance is adjusted before use, the lifting oil cylinder is controlled, the lifting oil cylinder drives the connecting rod to move, the connecting rod drives the stabilizing rod to move, and the limiting block at the lower end of the stabilizing rod moves in the movable groove, so that the top cover plate extrudes the springs to cooperate with the effect of rubber sheets, and then the influence of vibration generated in the construction process on the bottom surface is relieved.
