Description
Technical field
The utility model relates to instructional technology field, in particular to a kind of apparatus for demonstrating of hand press.
Background technology
Forcing press is a kind of versatility forcing press of delicate structure. Have of many uses, production efficiency high, forcing press can be widely used in the techniques such as cut-out, punching, blanking, bending, riveted and shaping. Make metal generation plastic deformation and fracture be processed into part by metal blank being applied to powerful pressure, multiplex at mechanical field. Forcing press also often occurs at teaching field, teacher also can often mention in course explanation process, but there is no actual model in the process of course explanation, and teacher can only carry out theoretic explanation, can not allow student carry out more deep and thorough understanding, also make student's learning interest lower.
Utility model content
The purpose of this utility model is to provide a kind of apparatus for demonstrating of hand press, to address the above problem.
For realizing the utility model object, the technical scheme of employing is: a kind of apparatus for demonstrating of hand press, comprise base, and on described base, be provided with vertical column, and workpiece plate is installed on base; On described column, be fixed with fixed head, and gear and tooth cover are installed on fixed head; In described tooth cover, be provided with tooth bar, and rack and pinion engagement; Described tooth bar lower end is fixedly installed pressure head.
Further, the turning cylinder of described gear is movably set with on fixed head, and turning cylinder is provided with handle through fixed head.
Further, described pressure head be positioned at workpiece plate directly over.
The beneficial effects of the utility model are, by turning handle, gear is rotated, by wheel and rack engage make gear rotate time tooth bar is moved up and down, in the time that tooth bar moves to minimum point, the pressure head of tooth bar below can apply certain pressure to the workpiece on workpiece plate, makes workpiece produce plastic deformation. The utility model can effectively guide student's study; Allow the more deep and thorough study of student and understanding, cause student's learning interest.
Brief description of the drawings
Fig. 1 is the front view of the apparatus for demonstrating of the hand press that provides of the utility model;
Fig. 2 is the side view of the apparatus for demonstrating of the hand press that provides of the utility model;
Mark and corresponding parts title in accompanying drawing:
1, base, 2, column, 3, fixed head, 4, gear, 5, tooth bar, 6, tooth cover, 7, pressure head, 8, workpiece plate, 9, handle.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
The apparatus for demonstrating of Fig. 1, Fig. 2 are shown a kind of hand press that the utility model provides, comprises base 1, is provided with vertical column 2, and on base 1, workpiece plate 8 is installed on described base 1; On described column 2, be fixed with fixed head 3, and gear 4 and tooth cover 6 are installed on fixed head 3; In described tooth cover 6, be provided with tooth bar 5, and tooth bar 5 engages with gear 4; Described tooth bar 5 lower ends are fixedly installed pressure head 7. The turning cylinder of described gear 4 is movably set with on fixed head 3, and turning cylinder is provided with handle 9 through fixed head 3, and handle 9 conveniently makes gear 4 rotate. Described pressure head 7 be positioned at workpiece plate 8 directly over, do not need in addition to the workpiece alignment on pressure head 7 and workpiece plate 8.
Turning handle 9 rotates gear 4, is engaged when gear 4 is rotated tooth bar 5 is moved up and down by gear 4 with tooth bar 5, and tooth cover 6 can effectively prevent that tooth bar 5 from dropping. In the time that tooth bar 5 moves to minimum point, the pressure head 7 of tooth bar 5 belows can apply certain pressure to the workpiece on workpiece plate 8, makes workpiece produce plastic deformation. The utility model can effectively guide student's study; Allow the more deep and thorough study of student and understanding, cause student's learning interest.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations. All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
