Now narrate its operation principle,
Profile of the present utility model is seen Fig. 1,
When mentioning handle, the imprint head patrix ejects external, sees all 4 Fig. 5 for duty, and file (25) is placed between the imprint head upper and lower mould, presses handle, promptly finishes coining manipulation.To go up die and push in the housing, handle falls after rise automatically, for off working state is seen Fig. 2 Fig. 3.
As seen from the figure, the two states of imprinter is directly to be interacted by handle and imprint head to keep, and specifically, needs to produce certain motion their strong transmission each other in other words between handle and the imprint head.Fig. 5 Fig. 8 is the working state figure of imprinter, imprint head is by last among the figure, following two parts constitute, be called, lower mold body (2), (3), wherein be equipped with, following die, on, the motion connected mode of lower mold body is similar to general stapler---and with connecting axle (15) that two parts are hinged, and change the shell fragment in the stapler into spring (16), as the parts that play return action, upper die body (2) can be made 180 ° of circular motion with respect to lower mold body (3) around connecting axle (15), when carrying out coining manipulation, upper die body (2) head is applied certain power, making it to move until interlock with respect to lower mold body (3)---closing position behind the complete operation, discharges power, upper die body (2) is returned to free state under the effect of spring (16)---deployed position, prepare next operation.Because the effect of support (6) makes imprint head when deployed position, patrix (4) and counterdie (5) are the state of being parallel to each other, and when closing position, counterdie (4) still is in parastate with patrix (5) with respect to being stamped file.
In coining manipulation, handle is equivalent to direct application of force person, it has bearing pin (10) and cam (9), bearing pin (10) is used for linking to each other with support (6), cam (9) is used for contacting with the upper die body (2) of imprint head, so just can handle the motion of imprint head, upper die body (2) has boss (13), and the cam on the handle (9) is meshed with boss (13), sees Fig. 3, in the time of on a downward power being delivered to handle (1), by cam (9) oppression boss (13), thereby power is delivered on the die, support (6) is a load-bearing component, about having two, link to each other with lower house (8), make with steel, the spring (18) between lower house (8) and imprint head lower mold body (3) is used for the location, when spring (18) when outwards stressing on imprint head, make it enter duty.
The material of the utility model imprinter removes support, and outside bearing pin and the spring, all the other available engineering plastics are made, and have both alleviated weight, can satisfy its performance requirement again.
Below we will be to Fig. 3, it is shown in Figure 5 that two states---store status and duty are carried out specific description.
Fig. 3 is the store status of imprinter, under this state, handle (1) horizontal positioned, imprint head upper die body (2) shrinks in housing (7,8) inside, keep this state, need a pair of opposite power to act on imprint head simultaneously, at first handle (1) head cam (9) Background Job face contacts with the leading flank of upper die body boss (13), produce the thrust that imprint head is moved backward, spring (18) acts on the washer (17) of lower mold body (3) bottom simultaneously, produce one and make the proal thrust of imprint head, these two power have formed a flywheel moment with respect to bearing pin (10), this moment trends towards making handle (1) to keep store status---horizontal level, and therefore no matter which kind of position imprinter is in, handle (1) keeps this invariant position.
When imprinter becomes Fig. 5 state from Fig. 3 state, when opening, only need handle (1) is lifted in order to use.The power of lifting that handle (1) is applied make cam (9) in the face of boss (13) side produce one after pressure, be delivered on the spring (18), make it compressing spring, but cam (9) can not leave boss (13) side and reach duty, small lugs (12) on the handle (1) can be with this in conjunction with removing, handle (1) make move on the cam (9) in, small lugs (12) contacts with imprint head upper end (14), promoting it moves downward, cam (9) break away from the side and on move on to boss (13) end face, the while imprint head is subjected to the promotion generation of energy storage in the spring (18) and jumps into, be in position as shown in Figure 5, need to prove, one long side surface of handle cam this moment (9) is meshed with boss (13) end face, and support handle (1) is in deployed position, and spring (16) makes handle (1) keep this stand-by state constant by upper die body (2), until the user filing paper (25) is filled in, between following die, carry out coining manipulation.
Figure 8 shows that the situation of imprint head impression file, handle (1) rotates around bearing pin (10), makes cam (9) belling platform (13) end face downwards---and on the driven surface, promote patrix (2) and move downward and counterdie (3) interlock mutually, carry out the coining manipulation on file.
When the impression beginning; upper die body (2) is parallel with lower mold body (3); upper die body (2) is pressed angular movement with respect to connecting axle (15); because this accurate motion; (5) two fore-ends of last die (4) and following die will at first contact; because of imprint head is to make by having flexible engineering plastics; the continuous downforce of handle (1) makes; following die (4); (5) surface fully contacts; so force of impression starts from the outside of die; and continuous whole occlusal surfaces of touching by seal; finish until whole impression; that is to say; in the process that handle moves downward; with downforce gradually ecto-entad impose on die; the patrix of common imprinter is along moving with the perpendicular direction of counterdie; downforce is this time acting on whole die in the motion; as seen; the utility model imprinter is because its special application of force formula and more common in use imprinter is laborsaving; support (15) role can not be ignored in addition; it had both born the pressure on the handle, again handle was played a supportive role the pressure on the release lever; under the effect of spring (16), die returns to the operation original state.
If will get back to store status at this moment, then promote the imprint head front end to enclosure interior, spring (18) compression, cam (9) leaves boss (13) end face and falls into boss (13) front end, under the thrust of spring (18), contact with boss (3) leading flank, be back to position shown in Figure 3.
