The utility model discloses automatic cold extrusion equipment for machining a double-end spline shaft. The automatic cold extrusion equipment mainly comprises a machine body, a feeding mechanism, a discharging mechanism, a pipe expanding clamping die, a gear extruding clamping die, a first pipe expanding mechanism, a second pipe expanding mechanism, a first gear extruding mechanism, a second gear extruding mechanism and a piece moving mechanism. By the adoption of the automatic cold extrusion equipment for machining the double-end spline shaft, a blank pipe can be reliably fixed through the pipe expanding clamping die and the gear extruding clamping die, the deflection problem is avoided, the machining precision is guaranteed, and due to the fact that the mode of pipe expanding and extruding at the two ends at the same time is adopted, the production takt is reduced by 50%, and the production efficiency is improved. The coaxiality and the straightness of the splines at the two ends of the shaft are improved, and meanwhile, the extrusion force is reduced, so that the tooth shape is fuller and more stable; and moreover, the part moving mechanism adopts a three-position synchronous part moving mode, so that the pipe expanding procedure and the gear extruding procedure can be carried out at the same time, the risk of machining consistency caused by part moving is greatly reduced, and the machining precision of splines at the two ends of the shaft is improved.

The utility model discloses a kind of pipe column inner and outer spline integrated forming tool and equipment, wherein, pipe column inner and outer spline integrated forming tool includes press mould and piece moving mechanism, press mould includes the first die holder and the second die holder that can be mutually close or far away, a pair of outer spline extrusion tooth mould and inner spline extrusion tooth mould and multiple pairs of pipe reducing male die and pipe reducing female die are arranged on the first die holder and the second die holder. First, the diameter of the two ends of pipe column is reduced by multiple pairs of pipe reducing male die and pipe reducing female die in multiple times, so that the shrinkage of each diameter reduction section is controlled within reasonable range, effectively avoid the problem that extrusion fails due to excessive extrusion force causing pipe column to bend, thereby greatly improving the yield rate, reduce production cost, and, the pipe column inner and outer spline integrated forming tool is added by piece moving mechanism, the transfer of feeding process, pipe reducing process, extrusion tooth process and discharging process can be realized, so that the processing of pipe column can be fully automated.

The invention discloses a skull dissection support convenient to adjust, and relates to the technical field of skull dissection supports, the skull dissection support comprises a bottom frame and a placing frame, and a local adjusting assembly is arranged at the top of the bottom frame. According to the skull dissection support convenient to adjust, in the skull dissection process, when a certain position of the skull needs to be lifted, an operator holds the containing frame with one hand, the other hand pushes a connecting ring rod on the lower portion, the second hydraulic cylinder is moved to the position below the position needing to be adjusted, and then the second hydraulic cylinder is moved to the position below the position needing to be adjusted; then a first hydraulic cylinder is adjusted to drive extrusion teeth on an extrusion plate to make contact with the outer side of an annular adjusting rail, two triangular sliding blocks are limited, then the hydraulic cylinder is adjusted to drive a connecting block to ascend and descend, in the ascending and descending process of the connecting block, ascending and descending of the local position of the containing frame are achieved, and the containing table at the deflection rod corresponding to the connecting block ascends and descends; adjustment of the needed position in the skull dissection process is achieved through the local adjusting assembly, and the effect that the skull does not need to be disassembled and assembled repeatedly is achieved.

The utility model relates to the technical field of toothbrushes, and particularly discloses an antibacterial toothbrush for hotels, which comprises a handle and a brush head, the brush head is fixedly connected to one end of the handle, a push rod is arranged in the handle, a toothpaste bag is arranged in the brush head, the other end of the handle is fixedly connected with a rubber cover, and the rubber cover is fixedly connected with a toothbrush handle. A supporting frame is arranged in the rubber cover and fixedly connected with one end of a push rod. Through the structures of the push rod, the push block, the top plate, the conical block, the discharge holes and the like, uniform extrusion of toothpaste is realized, when the push block is pushed, the top plate ascends to extrude the toothpaste bag, the conical block punctures the toothpaste bag to enable the toothpaste to overflow, and the toothpaste is uniformly distributed around the bristles through the discharge holes, so that non-uniform distribution of the toothpaste during tooth brushing is avoided; meanwhile, due to the fact that no additional rubber brush block or other objects are arranged on the surface of the brush head, the comfort degree during tooth brushing is guaranteed, tooth brushing actions cannot be blocked, and the overall use experience is improved.

The present application relates to the technical field of precision extrusion processing, in particular to a high-efficiency cold extrusion forming process for a fuse body, comprising the following steps: S1, feeding the cylindrical coil material steel wire to the press by using an automatic feeding device, and cutting the cylindrical coil material into cylindrical sections on the press; S2, automatically feeding the cylindrical sections into the extrusion die of the progressive die for extrusion upsetting; S3, automatically feeding the rod-shaped sections into the extrusion die of the progressive die for multi-stage extrusion, and finally forming the fuse body structure with a cap-shaped head, a middle diameter section and a small diameter section; S4, automatically feeding the fuse body structure into the extrusion tooth die, machining the middle diameter section into a tooth shape in the extrusion tooth die, and finally forming a complete fuse body; and S5, after all the processes are completed, cleaning and quality inspecting the fuse body. The present application solves the technical problems of complex process steps, low previous machining precision, low machining efficiency and high production cost in the prior art when machining small fuse bodies with teeth.
