The invention provides a cooperative tail pushing device for fixed-length shears and a control method of the cooperative tail pushing device, and relates to the technical field of large rolling shear equipment for wide and thick plates in the metallurgical industry. Each tail pushing device comprises a hydraulic cylinder, a swing arm mechanism, a push plate mechanism, a connecting rod mechanism, a spring mechanism and a positioning detection system. The hydraulic cylinder drives the swing arm mechanism to drive the connecting rod mechanism and the spring mechanism to act together, so that the push plate mechanism pushes the tailing steel plate to fall into the waste collecting device. The external contour of the tailing steel plate is recognized through the positioning detection system, the number of the groups of the tail pushing devices is judged according to the size data, cooperative steel pushing of the multiple groups of tail pushing devices is achieved, redundant equipment is prevented from being put into work, and energy conservation and consumption reduction are embodied; a plurality of groups of tail pushing devices are directly mounted on the fixed-length shear front panel, so that transverse movement is avoided to adapt to the width of a tailing steel plate, the equipment structure is simplified, the cost input is reduced, and the working efficiency is improved.

The utility model relates to the technical field of metallurgical mechanical equipment discloses a drag out roller lifting device convenient to maintain, including machine outside centring base and drag out roller support still include rotation transmission mechanism and lifting drive unit, the drag out roller support rotatablely connects on machine outside centring base through a rotating shaft, the rotation transmission mechanism includes a transmission axle, a swing arm and at least one bearing seat, the transmission axle is fixedly installed on the upper plane of machine outside centring base through bearing seat, one end of swing arm is fixedly covered on the transmission axle, and the other end is hinged with the bottom of drag out roller support, this drag out roller lifting device convenient to maintain, through the linear thrust of oil cylinder conversion is the rotary torque to transmission axle, oil cylinder no longer directly bears the partial load and impact load of drag out roller base, and the working condition is fundamentally improved.

The present invention relates to a novel horizontal mixer stirring shaft, which is composed of a horizontal stirring shaft and a spiral mixing blade fixed thereon. The mixing blade is arranged in multiple sections non-continuously, and the sections of the main mixing blades adjacent to each other in front and behind and intermittently arranged along the axial direction of the horizontal stirring shaft are staggered in sequence at a certain angle along the radial direction of the main shaft, and a return mixing blade is arranged in the middle of the angle between the two sections of the main mixing blades adjacent to each other along the axial direction of the horizontal stirring shaft. The main mixing blade and the return mixing blade are adopted to prevent the flexible strip material from being easily entangled or entangled, thereby reducing or avoiding the labor cost, production loss and harm to personnel health and operating environment caused by regular cleaning. The rotation direction of the return mixing blade is opposite to that of the main mixing blade, thereby enhancing the stirring intensity and improving the mixing effect. The horizontal stirring shaft can rotate forward or reversely, and the return mixing blade has an opposite rotation direction to the main mixing blade. Regardless of whether the horizontal stirring shaft rotates forward or reversely, the direction in which the return mixing blade pushes the material is opposite to that of the main mixing blade, further improving the mixing effect.

This utility model relates to the technical field of forging sorting equipment, specifically an automatic forging sorting device based on alternating flipping and positioning control, suitable for sorting forgings of different specifications or batches; an alternating forging sorting device includes a frame; multiple V-shaped rollers evenly arranged along the length of the frame to form a linear forging conveying system; a motor located at one end of the frame and driving the V-shaped rollers to rotate via a sprocket and chain; two V-shaped material racks symmetrically arranged on both sides of the frame's width for sorting forgings; two sets of flipping components, corresponding to the V-shaped material racks on both sides and working alternately, each set including a first cylinder, a support rod, a connecting rod, and multiple pallets; the support rod is laterally rotatably connected to the frame, and multiple pallets are spaced and sleeved on the support rod with one end passing through the roller gap; the connecting rod connects each pallet through, and the first cylinder is hinged to the frame and connected to the connecting rod via a spherical bearing, driving the pallets to flip around the support rod to side-flip and lift the forgings into the corresponding material rack.

The utility model discloses a welding device for copper wire connection, which comprises a support frame, the upper surface of the support frame is fixedly connected with a fixing frame, the inner wall of the fixing frame is slidably connected with an ejector rod, the bottom end of the ejector rod penetrates through the upper surface of the support frame and extends to the inner top wall of the support frame, and the top end of the ejector rod is rotatably connected with a lower roll shaft. According to the welding device for copper wire connection, through the arrangement of the supporting frame, the fixed frame, the ejector rod, a lower roller shaft, a transverse rod, a movable frame and a driving motor, when the ejector rod moves upwards, an auxiliary wheel of the movable frame can be ejected upwards through an ejector block and is driven to rotate, and at the moment, the movable frame rotates on the transverse rod and can eject a copper wire tightly through a side roller shaft and the lower roller shaft; when the top block slides downwards, the side roll shaft can be prevented from clamping the copper wire, and when the driving motor runs, the output end of the driving motor can drive the side roll shaft to rotate, so that the copper wire can be driven to rotate when the copper wire is clamped, and the copper wire is more convenient to weld.
