Description
Technical field
The utility model relates to the technical field of teaching equipment, especially relates to a kind of hand press demonstration model for teaching.
Background technology
Pressing machine is the common equipment in pressure processing, when needed pressure hour may be selected hand press.Also have people by hand press for teaching demonstration.The hand press using at present utilizes lever principle design substantially, has the advantages that action is fast, efficiency is high.But during for teaching demonstration, there is following problem: the one, weight shows slightly to lay particular stress on and is not easy to carry, and the 2nd, the speed of slide block is wayward, and the 3rd, pressure size is stable not.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to be to provide a kind of simple in structure, easy to use, portable hand press demonstration model for teaching.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of hand press demonstration model for teaching, formed by worktable, two sidewalls, entablature, slide block and drive screws, both sides on worktable are fixed with two sidewalls that arrange perpendicular to worktable by pin respectively, the top of two side is fixedly connected with by screw with entablature respectively, described slide block is located in the space of worktable, two sidewalls and entablature composition and can be slided up and down, on the upper surface of slide block, slide and be positioned with the tail end of drive screw, the head end of drive screw is fixedly connected with the handwheel that is positioned at entablature top through entablature.
The utility model is further set to: the concrete structure of tail end that is positioned with drive screw that slides on the upper surface of described slide block is: the tail end of drive screw is provided with ring groove, is fixed with the gland stretching in ring groove on the upper surface of slide block.
The utility model is further set to: described gland is that symmetrically arranged two docking form.
The utility model is further set to: on the madial wall of described two sidewalls, be equipped with vertical chute, the two ends of slide block are slidedly arranged on respectively in chute.
By adopting technique scheme, the technique effect that the utility model reaches is:
1, this apparatus structure is simple, is easy to manufacture low cost of manufacture;
2, easy to operate, in use, without complicated operation, it is convenient to load and unload;
3, mechanism exposes, and movement velocity is slower, good demonstration effect;
4, not only can play configuration, can also demonstrate process, can also bear low load processing tasks;
5, the utility model also can be for engineer testing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the plan structure schematic diagram of biopsy cavity marker devices of the present utility model.
Specific embodiment
As Fig. 1, shown in Fig. 2, for the disclosed a kind of hand press demonstration model for teaching of the utility model, by worktable 1, two sidewalls 3, entablature 6, slide block 4 and drive screw 7 form, both sides on worktable 1 are fixed with two sidewalls that arrange perpendicular to worktable 13 by pin 3 respectively, the top of two side 3 is fixedly connected with by screw 5 with entablature 6 respectively, described slide block 4 is located at worktable 1, in the space that two sidewalls 3 and entablature 6 form, can slide up and down, on the upper surface of slide block 4, slide and be positioned with the tail end of drive screw 7, the head end of drive screw 7 is fixedly connected with the handwheel that is positioned at entablature 6 tops through entablature 6.Described worktable 1 be shaped as rectangular parallelepiped, the left and right sides symmetry of worktable 1 is offered type hole, for fixed sidewall 3 is installed, the cross sectional shape of the shape in type hole and sidewall 3 matches, size also keeps interference fit with sidewall 3 sectional dimensions.
In above-mentioned, the concrete structure of tail end that is positioned with drive screw 7 that slides on the upper surface of described slide block 4 is: the tail end of drive screw 7 is provided with ring groove 70, is fixed with the gland 8 stretching in ring groove 70 on the upper surface of slide block 4.Described gland 8 forms for symmetrically arranged two docking.Gland 8 is two semilune parts, its effect is be connected drive screw 7 and slide block 4, the vertical direction sectional structure of gland 8 as shown in Figure 1, its flange portion gos deep in the groove of drive screw 7 lower ends with the relatively moving of constraint drive screw 7 and slide block 4, and gland 8 offers screw hole for gland 8 and the slide block 4 of being connected.
In above-mentioned, be equipped with vertical chute 9 on the madial wall of described two sidewalls 3, the two ends of slide block 4 are slidedly arranged on respectively in chute 9.
Hand press demonstration model for teaching described in the present embodiment, can be used for pressing machine teaching demonstration, also can be used for low load pressure processing.The slide block movement speed of this demonstration model for teaching is slower, and structure expose be convenient to observe, teaching demonstration effect is better.When the man-hour that adds under low load, be suitable for the slow processing of requirement, as the drawing of punching press, bending, shaping and the powder metallurgy powder compacting in manufacturing etc.
To sum up, the use of this demonstration model for teaching divides following four steps: the first step is utilized the T-slot fixed mould on slide block and worktable; Second step is put into needs compressing blank or material; Wheel (screw thread be left-handed should rotate counterclockwise) is started in the 3rd step dextrorotation to be moved down slide block to implement compacting, mould closure; The 4th step rotates counterclockwise handwheel and makes to retract journey on slide block, and mould opens; The 5th step is taken out the workpiece suppressing.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
