Description
Technical field
The utility model belong to metallic plate or pipe, rod or section bar substantially without machining or process field, be specifically related to a kind of aluminium spot punch device.
Background technology
The goods that aluminium is manufactured by aluminium and other alloying element.After being normally first processed into casting piece, forged article and paper tinsel, plate, band, tube, rod section material etc., then make through operations such as clod wash, sawing, boring, assembled, colourings.Main metal element is aluminium, is adding alloying elements, improves the performance of aluminium.
In aluminium production process, usually to bore a hole on aluminium, manufacture the aluminium that can directly install.But in use, in order to easy for installation, usually also to supplement perforation, if supplement perforation will turn back to producer's processing, then can stop over the use of aluminium.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of aluminium spot punch device that manually can supplement perforation to aluminium.
For achieving the above object, the technical solution of the utility model is:
Aluminium spot punch device, comprise control crank, lever arm, connecting rod, cam, perforation nail and hardwood backing plate, be provided with two described lever arms positioned opposite, connecting rod two ends respectively with two lever arms in the middle part of hinged, two lever arm one end are all hinged with described cam, two cams are arranged symmetrically with, the surface of cam is provided with gear, tooth on two cams is meshed, described control crank is fixedly connected with one of them cam, described perforation nail is connected to the inner side of a lever arm away from cam one end, described hardwood backing plate is embedded on another lever arm, and hardwood backing plate is oppositely arranged with perforation nail.
When adopting technique scheme, first aluminium punch position to be perforated is marked, then place it between perforation nail and hardwood backing plate, perforation is followed closely align with the punch position indicated, then the control crank on a cam is pulled, control crank is fixedly connected with this cam, and two lever arm one end are all hinged with described cam, so cam rotates, gear on two cams be arranged symmetrically with is meshed, so, eccentric throw when two cam contact positions is changed from small to big in process, two lever arms are softened, connecting rod two ends respectively with two lever arms in the middle part of hinged, form lever, so two lever arms are close near perforation nail one end, wait that the aluminium side supplementing perforation is supported on hardwood backing plate, perforation nail just can from aluminium opposite side punched out on aluminium.The utility model adopts cam, lever arm, connecting rod and perforation nail etc., utilizes lever principle, manually can supplementing perforation to aluminium, without the need to returning manufacturer's supplementary processing again, not affecting the use of aluminium.
Further, two cams are equipped with control crank, two control cranks are also arranged symmetrically with.Exert a force on two control cranks, the power that perforation nail can be made to be applied on aluminium is larger, bores a hole easier simultaneously.
Further, the spacing of described connecting rod and cam is the twice of the spacing that connecting rod is followed closely with perforation.Such arm of force that the arm of force of force side can be made to be greater than threaded end, thus can ensure to apply less power in force side, just can bore a hole on aluminium.
Further, described perforation nail is threaded with lever arm.The mode of this connection is convenient to the perforation nail changing different size, and this connected mode is simple.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model aluminium spot punch device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: cam 1, control crank 2, lever arm 3, hardwood backing plate 4, perforation nail 5, connecting rod 6.
As shown in Figure 1, a kind of aluminium spot punch device, comprise control crank 2, lever arm 3, connecting rod 6, cam 1, perforation nail 5 and hardwood backing plate, be provided with two lever arms 3 positioned opposite, connecting rod 6 two ends respectively with two lever arms 3 in the middle part of hinged, two lever arm 3 one end are all hinged with cam 1, two cams 1 are arranged symmetrically with, the surface of cam 1 is provided with gear, tooth on two cams 1 is meshed, control crank 2 is fixedly connected with one of them cam 1, perforation nail 5 is connected to the inner side of a lever arm 3 away from cam 1 one end, hardwood backing plate 4 is embedded on another lever arm 3, and hardwood backing plate 4 is oppositely arranged with perforation nail 5.
In the present embodiment, two cams 1 are equipped with control crank 2, two control cranks 2 are also arranged symmetrically with.Exert a force on two control cranks 2, the power that perforation nail 5 can be made to be applied on aluminium are larger, bore a hole easier simultaneously.
Connecting rod 6 and the spacing of cam 1 are the twice of the spacing of connecting rod 6 and perforation nail 5.Such arm of force that the arm of force of force side can be made to be greater than threaded end, thus can ensure to apply less power in force side, just can bore a hole on aluminium.
Perforation nail 5 is threaded with lever arm 3.The mode of this connection is convenient to the perforation nail 5 changing different size, and this connected mode is simple.
Specific works principle:
First aluminium punch position to be perforated is marked, then place it between perforation nail 5 and hardwood backing plate 4, make perforation follow closely 5 to align with the punch position indicated, then pull the control crank 2 on two cams 1 simultaneously, control crank 2 is fixedly connected with cam 1, and two lever arm 3 one end are all hinged with described cam 1, so two cams 1 rotate simultaneously, gear on two cams be arranged symmetrically with 1 is meshed, so, when the eccentric throw of two cam 1 contact positions is changed from small to big in process, two lever arms 3 are softened, connecting rod 6 two ends respectively with two lever arms 3 in the middle part of hinged, form lever, so two lever arms 3 are close near perforation nail 5 one end, wait that the aluminium side supplementing perforation is supported on hardwood backing plate 4, perforation nail 5 just can from aluminium opposite side punched out on aluminium.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
