Description

Conduit punch structure

Technical field

The utility model relates to a kind of conduit punch structures, belong to conduit processing technique field.

Background technique

Conduit (breathing out fragrant slot) is a kind of built-in fitting for building, often uses with rivets, plays the work being connected and fixed With, conduit with need first to carry out punching technology before rivet, in order to realize that one set of die rushes the site requirement in different holes, I Company has developed a kind of punching machine double joint mold general assembly, as shown in Figure 1, including lower mold 1 and upper mold 4, lower 1 upper end of mold is equipped with Two guide shafts 2,4 lower end of upper mold are set there are two guide sleeve 3,3 sets of guide sleeve on guide shaft 2,4 lower end of upper mold is fixed with red needle seat 7,7 lower end of red needle seat is equipped with red needle, and die case mounting plate 13 is fixed on lower mold 1, and die case mounting plate 13 is equipped with recessed Die sleeve 11 is equipped with directive wheel 12, wherein between upper mold 4 and the red needle seat 7 between die case mounting plate 13 and withdrawing plate 10 Two guide rails 14 are fixed with, selection cylinder 5 is fixed on the rear end face of upper mold 4, are selected fixed on the piston rod of cylinder 5 Equipped with a selection sliding block 6, the both ends of sliding block 6 is selected to be located on guide rail 14, opened up on red needle seat 7 there are four hole, this four holes Interior installation is there are two types of red needle, including red needle 1 and red needle 29, and the die case 11 that die case mounting plate 13 is equipped with is four, often A 11 size of die case is corresponding with the red needle of surface.In use, conduit reaches punching position under the action of directive wheel 12 It sets, cylinder 5 is selected to push selection sliding block 6 selection red needle 1 or red needle 29 as needed, then control upper mold 4 and transport downwards It is dynamic, operation can be punched out.

But existing red needle and die case unreasonable structure, the punch end face of red needle and the cutting hole top of die case Edge is plane, and during practical application, since cylinder action is rapid, red needle intensity is high, cutting edge is sharp, the shape of conduit There are factors such as more or less errors, when leading to many times downward punching of red needle, conduit is not direct with die case Effect, only relies on the downward impact of red needle and just goes out hole, and red needle damaged condition is caused to increase, and service life is much smaller than the design longevity Life, has seriously affected equipment normal use.

Utility model content

According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: one kind is provided can be effective Improve the conduit punch structure of red needle service life.

Conduit punch structure described in the utility model, including red needle and die case, red needle are successively arranged base from top to bottom Body, reinforcement part and formed punch, die case are equipped with cutting hole, and the nose of punch of red needle is successively arranged matching for reverse frustoconic from top to bottom Conjunction portion and hemispheric impact portion, the top edge of the cutting hole of die case are equipped with the mating groove to match with auxiliary section.

Possessed beneficial effect is the utility model compared with prior art:

Conduit punch structure described in the utility model, is punched out by the cooperation of red needle and die case, is effectively improved The service life of red needle, so that the stability in use of equipment is improved, meanwhile, the frequency of replacement red needle is reduced, to drop Low production cost.

Specific embodiment

The embodiments of the present invention are described further with reference to the accompanying drawing:

Embodiment 1:

As shown in Figures 2 to 4, conduit punch structure described in the utility model, including red needle and die case 11, red needle is certainly Matrix 15, reinforcement part 16 and formed punch 17 are successively arranged under above, die case 11 is equipped with cutting hole 18,17 end of formed punch of red needle It is successively arranged auxiliary section 19 and the hemispheric impact portion 20 of reverse frustoconic, the top of the cutting hole 18 of die case 11 from top to bottom Edge is equipped with the mating groove 21 to match with auxiliary section 19.

The depth of mating groove 21 about 3mm, the high about 2mm of auxiliary section 19, the high about 1mm of impact portion 20, when punching, red needle Impact portion 20 is first contacted with conduit, and a pit is gone out on conduit, then the outer surface of the auxiliary section 19 of red needle and cavity plate The surface engagement of mating groove 21 on set 11, and gone out hole using red needle and the cutting edge of die case 11, avoid red needle folk prescription Face punching damages itself bring, greatly improves the service life of red needle.

Conduit punch structure described in the utility model, is punched out by red needle and the cooperation of die case 11, is effectively mentioned The high service life of red needle, so that the stability in use of equipment is improved, meanwhile, the frequency of replacement red needle is reduced, thus Reduce production cost.

Embodiment 2:

As shown in Figure 5, Figure 6, on the basis of embodiment 1, between 15 three of the formed punch 17, reinforcement part 16 and matrix It is coaxially set.

Conduit punch structure described in the utility model, is punched out by red needle and the cooperation of die case 11, also, is rushed Needle self-strength is higher, effectively increases the service life of red needle, so that the stability in use of equipment is improved, meanwhile, it reduces The frequency of replacement red needle, to reduce production cost.

Embodiment 3:

As shown in Figure 7, Figure 8, on the basis of embodiment 1, the axis of the reinforcement part 16 is located at the axis of matrix 15 Left side, the axis of formed punch 17 are located on the left of the axis of reinforcement part 16.

Conduit punch structure described in the utility model, effectively increases the service life of red needle, to improve equipment Stability in use, meanwhile, reduce replacement red needle frequency, to reduce production cost.In addition, special being wanted for some It asks, at second hole of conduit end point and the closer pitch requirements in first hole, punching requirement can also be met, widened whole The use scope of machine equipment.
