The utility model discloses a kind of for winding pipe high-speed wear-resistant type sizing sleeve, it is related to winding pipe production equipment technical field, including cooling copper base, one end of cooling copper base is installed on extrusion die head, the other end of cooling copper base is fixedly installed with connecting disc, connecting disc is fixedly installed with four groups of disc screw rod of annular array distribution in the side away from cooling copper base, several forming disc are installed on disc screw rod, the installation interval of forming disc from the side close to connecting disc to the side away from connecting disc increases sequentially;The utility model changes the boss shape of cooling copper base, so that transition disc does not contact with raw material, reduces replacement frequency;Meanwhile, forming disc uses high carbon steel to carry out hardness treatment, increases self hardness, contact surface carries out polishing treatment, improves service life.

The utility model relates to building technical field especially a cup mouth foundation steel structure column installation horizontal positioning tool, including four resistance positioning mechanism, four resistance positioning mechanisms two two symmetry settings, every resistance positioning mechanism includes clamping mechanism, two fixed plates are fixed on the clamping mechanism symmetry, two fixed plates are common and are equipped with first threaded rod and are screwed, the first threaded rod one end rotates and is equipped with resistance plate, the other end is equipped with first hand wheel fixedly, the utility model discloses when using, utilize four clamping mechanisms and fix on the four around of pouring concrete fence, subsequently utilize the screwing of first threaded rod to promote resistance plate, utilize multiple resistance plates and stop up steel structure column, and then adjust the perpendicularity of steel structure column and adjust, and simple preparation, low cost can be used, in addition, the contact area of multiple resistance plates and steel structure column is big, and simultaneously, the contact area is also enough flat, can ensure the adjustment of steel structure column perpendicularity adjustment.

The invention relates to the technical field of diode processing, in particular to tin storage equipment for photovoltaic module diode processing, which comprises a belt conveyor, the side wall of the belt conveyor is fixedly connected with a shell, the side wall of the shell is fixedly connected with a linear driver, and the moving end of the linear driver is fixedly connected with the top of a first electric push rod. The lower end of the first electric push rod is connected with a vacuum suction pen, and the side wall of the lower end of the first electric push rod is fixedly connected with a magnetic block. And the side wall of the belt conveyor is fixedly connected with a placing frame. In the process that a tin block taking area is moved to an ultrasonic vibration head and tin block machining area, a driving gear is automatically driven to rotate by utilizing the moving power of a belt, so that a grinding plate moves back and forth to grind the contact area of a tin block and a cooling fin, the contact surface is smooth, and the machining efficiency is improved. The contact area of the subsequent tin block and the radiating fin is increased, the subsequent tin block is ensured to be in close contact with the radiating fin, and effective transmission of ultrasonic energy is promoted.

A semiconductor structure and a forming method thereof, the forming method comprising: providing a substrate, including a substrate and a bottom fin material layer on the substrate, the substrate including a first device region and a second device region; forming a first fin material layer on the bottom fin material layer, the material of the first fin material layer being different from the material of the bottom fin material layer; removing the first fin material layer located at the second device region to form an opening exposing a top of the bottom fin material layer; forming a second fin material layer in the opening; and performing a fin patterning process to pattern the bottom fin material layer into a bottom fin, the first fin material layer into a first device fin standing on the bottom fin of the first device region, and the second fin material layer into a second device fin standing on the bottom fin of the second device region. The formed second device fin and the contact surface of the first device fin with the bottom fin are both relatively flat, improving the height consistency of the second device fin and the first device fin.

The utility model belongs to the field of logistics storage and transportation technology, concretely relates to a heavy load shuttle vehicle, device includes two fixed baffle of shuttle vehicle body and setting on two end portions, sets up between two fixed baffle and is located on the rear baffle and front baffle of two end portions of fixed baffle. The front baffle includes two respectively hinged on the end portion of two fixed baffle baffle structure. The utility model through the mode of rotation connection of front baffle and fixed baffle, both guaranteed the tray of carrying goods when entering the shuttle vehicle, the contact surface of tray is even, overcomes the problem of carrying jamming, and at the same time after the tray all enters the shuttle vehicle, the front baffle cooperates with the fixed baffle and constitutes the fixed space of limiting the tray sliding out through the mode of rotation, guarantees the stability of goods when the shuttle vehicle transportation.
