Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The all other embodiment obtained, belongs to the protection scope of the utility model.
The utility model embodiment is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of punch of the utility model, including bracket, vertical shaft 12 and crank mechanism；
Vertical shaft is mounted on bracket, and is passed through bracket and completed to be axially moved, and crank mechanism is mounted on bracket, is driven
The respective members of vertical shaft；By operating crank mechanism, the rotary motion of crank mechanism is converted into vertical shaft and is pumped；It is vertical
Axis generates the impact force moved back and forth, and the respective members cooperation with support section will punch article.
The bracket includes: column 1, upper cover 6, vertical plate 8, support plate 9 and pedestal 11, and column 1 is fixedly mounted on pedestal
On 11, support plate 9 is fixedly mounted in the upper end of column 1, and vertical plate 8 and upper cover 6 is fixedly mounted in the upper end of support plate 9；
The upper cover 6 is cylindrical shape made of metal, and upper end is top closed, and circular hole, bottom circle are had at top center
Tubular port is fixed on support plate 9.
Centre bore is had at the left side circle center of the support plate 9, right side is fixed on column 1.
The vertical shaft 12 includes: convex shoulder 5, spring 7, elongated slot 10, formed punch 15
The upper cylinder of vertical shaft 12 has convex shoulder 5, and spring 7 is installed between convex shoulder 5 and the top of upper cover 6, and spring 7 passes through
Vertical shaft is pressed to pedestal 11 by convex shoulder 5；
The middle part cylindrical sides of the vertical shaft 12 are provided with elongated slot 10.
12 upper end of vertical shaft passes through the circular hole at 6 top of upper cover, and centre passes through the centre bore of fixed plate 9, vertical shaft is limited
It is set to and slides up and down, formed punch 15 is installed in the lower end of vertical shaft 12.
The crank mechanism includes: semiaxis 13, runner 2, connecting rod 4, unilateral bearing 14 and rocking handle 3.
Semiaxis 13 can be rotated freely and cannot be moved axially behind the front side of upper cover 6 and vertical plate 8, and semiaxis 13 probes into elongated slot 10
Interior one end is fixedly connected with runner 2,4 hinge of rear side wheel rim and connecting rod of runner 2, the upper end of connecting rod 4 and the upper end of elongated slot 10
Hinge in the middle part of baseplane.
Unilateral bearing 14 is installed in the front end of the semiaxis 13, and rocking handle 3 is connect by unilateral bearing 14 with semiaxis 13, when
When rocking handle 3 drives semiaxis 13 to rotate, runner 2 drives connecting rod 4 to rotate, and vertical shaft 12 is lifted up or is put down.
The effect of unilateral bearing is that rocking handle 3 can drive semiaxis 13 to rotate, and turn when 13 revolving speed of semiaxis more than rocking handle 3
Cannot cannot be driven in turn when fast rocking handle 3 rotate so that rocking handle 3 rotate it is smooth.
Operating process:
Article to be punctured is placed on pedestal 11, by 3 sets of rocking handle in shaft 2, holds article to be punctured on the other hand,
Another hand shakes rocking handle 3 clockwise, does not produce relative rotation between the inner and outer rings of unilateral bearing 14 at this time, then 13 band of semiaxis
Turn wheel 2, connecting rod 4 rotate, vertical shaft 12 is lifted up, 5 compressed spring 7 of convex shoulder, vertical shaft 12 along bottom plate 9 centre bore and on
6 top circular hole of lid moves up, and after top dead centre is crossed in the upper end of connecting rod 4, the potential energy that spring 7 is put aside reaches maximum, rapidly
Elongation, pressure act on convex shoulder 5, medicine pestle assembly are moved down rapidly, so that the revolving speed of semiaxis 13 is more than the revolving speed of rocking handle 3, i.e.,
The inner ring revolving speed of unilateral bearing is greater than outer ring revolving speed, and vertical shaft 12 generates biggish impact force action under the effect of 7 restoring force of spring
On article to be punctured, article is punctured.When vertical shaft 12 is in extreme lower position, rocking handle 3 is continued to rotate, and semiaxis 13 is driven to revolve
Turn, crank link mechanism can again lift vertical shaft 12, and hole will be continuously got on article.
Compared with prior art, there are three important features compared to existing punch utensil for a kind of punch:
1, structurally reasonable, crank mechanism and unilateral bearing cooperate, so that easy to operate, smooth.
2, time saving and energy saving, the rotary motion of crank mechanism is changed into pumping for vertical shaft, single according to physical principle
Biggish revolving speed can be generated to rotary motion, without changing the action direction of power, energy loss is small, and per revolution is corresponding primary
Vertical shaft once pumps, so the speed of punching accelerates, and laborsaving.
3, compared to the punch of manual pressure, formed punch 11 is moved down under the restoring force effect of spring 7, the speed of operation
Degree is exceedingly fast, punched hole the smooth of the edge, neatly.
