The bottom wall of the stamping groove is provided with a drawing groove. The stamping mechanism comprises a stamping head and a stamping reset part. The stamping head is slidably connected to the frame body in the vertical direction. The stamping reset part is used for resetting the stamping head. The bottom of the stamping head is opposite to the stamping groove and is adapted to the shape of the stamping groove. The drawing mechanism comprises a drawing rod and a drawing reset part. The drawing rod is coaxially arranged in the stamping head and is slidably connected to the stamping head. The drawing reset part is used for resetting the drawing rod. The drawing rod is opposite to the drawing groove and is connected to the drawing groove in a plug-in mode. The application has the effects of facilitating the production and processing of brittle cylinder skin and improving work efficiency.

The utility model relates to a quick-release type turning tool for a self-centering angle valve body. The inclined die comprises an inclined die, a first positioning plane and a second positioning plane which form a second included angle, the second included angle is equal to the first included angle, the first positioning plane is provided with a second connecting hole and a second positioning hole corresponding to a first connecting hole and a first positioning hole respectively, and the second positioning plane is provided with a third connecting hole. After the angle valve body is installed on the inclined die, the axis of the inclined flange center runner is perpendicular to the second positioning plane. The fixed bottom plate comprises a third positioning plane attached to the second positioning plane, and a fourth connecting hole corresponding to the third connecting hole is formed in the third positioning plane; the first connecting piece is detachably connected between the first connecting hole and the second connecting hole; the second connecting piece is detachably connected between the third connecting hole and the fourth connecting hole; and the positioning column is mounted in the first positioning hole and is matched with the second positioning hole in a positioning and inserting manner. The device is convenient to disassemble and reliable in positioning.

The invention belongs to the technical field of asphalt concrete production, and particularly relates to an asphalt concrete production device which comprises a feeding mechanism, a temporary storage device, a reclaimed material stirring roller mechanism, a raw material stirring roller mechanism, a raw material asphalt cooling tank and a reclaimed material asphalt cooling tank. According to the scheme, the asphalt concrete production device can respectively process the raw material and the reclaimed material, so that the problem that the processing requirements of the reclaimed material and the raw material cannot be simultaneously met in the prior art is solved; a combustor is adopted to directly heat stones, so that the heat utilization rate is effectively improved, small-batch production of asphalt concrete can be realized under the condition of considering the heat utilization rate, the preheating time of the asphalt concrete production device in the scheme is shorter (about 12h), and the production is more flexible; the requirement for a construction site is lower, and conveying of products and raw materials is facilitated; and the feeding mechanism weighs and supplies different raw materials respectively, so that production and processing of asphalt concrete with different proportions are realized.

The utility model discloses a horizontal mold for a prefabricated hollow stair. The horizontal mold comprises a supporting frame, a bottom plate, side plates and end plates. A plurality of long pore-forming piles are horizontally and slidably connected to the outer wall of each side plate, the long pore-forming piles are used for sliding to the position above the bottom plate, supporting plates abutting against the outer walls of the side plates are arranged at the outer ends of the long pore-forming piles, and supporting rods are connected between the multiple supporting plates; sliding rails are horizontally arranged at the two ends of the side plate, the two ends of the supporting rod penetrate through the sliding rails and are provided with idler wheels matched with the sliding rails, hand wheels are arranged at the two ends of the supporting rod, and a locking mechanism for fixing the supporting rod is arranged on the side plate. The mould has the following advantages and effects that the long hole-forming piles which slide horizontally are arranged on the mould, so that standard through lightening holes can be formed in a formed stair after concrete is poured and vibrated, the dead weight of the stair is reduced while the structural strength of the stair is ensured, and the effects of standard hole forming and the structural strength of the stair are achieved.
