DETAILED DESCRIPTION

[0038] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0039] Reference Figure 2 The metal handle stamping device includes a frame 200, a lower die 300, a first upper die 400, a second upper die 500 and a linkage device 600.

[0040] Reference Figure 4 The lower edge of the frame 200 is provided with a notch 201, and the frame 200 is provided with a first inclined guide rail 204 corresponding to the left edge 202 of the notch 201 and inclined to the lower right, a second inclined guide rail 205 corresponding to the right edge 203 of the notch 201 and inclined to the lower left, and a third vertical guide rail 206 perpendicular to the horizontal plane. The notch 201 is used for packaging containers to pass through. Specifically, the packaging container is transported along the front-to-back direction by the container conveying mechanism. When it is transported to the notch 201, the transportation is suspended. The metal strip is stamped into a handle shape at the notch 201 and installed on the packaging container. After the installation is completed, the packaging container is continuously transported along the front-to-back direction by the container conveying mechanism, and the next packaging container is transported to the notch 201. This cycle is repeated to achieve the production and installation of the handle.

[0041] The lower die 300 is used to cooperate with the first upper die 400 and the second upper die 500 to stamp the metal strip after the two ends are bent to form a handle shape. Figure 2 and Figure 4 In this embodiment, the lower mold 300 includes a left molding block 330, an upper molding block 310 and a right molding block 320. The left molding block 330 is connected to the left edge 202 of the notch 201 by bolts, the right molding block 320 is connected to the right edge 203 of the notch 201 by bolts, and the upper molding block 310 is connected to the top of the notch 201 by bolts. The lower mold 300 in this embodiment is composed of a plurality of molding blocks, but the embodiment is not limited thereto, and the lower mold 300 may also be an integrated structure lower mold 300.

[0042] Combination Figure 2 , Figure 3 , Figure 4 and Fig.12 The upper mold of this embodiment includes two, namely, the first upper mold 400 and the second upper mold 500. In the mold opening state, the first upper mold 400 is located at the upper left side of the lower mold 300, and the second upper mold 500 is located at the upper right side of the lower mold 300. The first upper mold 400 is connected to the slider on the first inclined guide rail 204 by bolts, so that the first upper mold 400 can move to the lower right along the first inclined guide rail 204 to close the mold with the left molding block 330 of the lower mold 300, and can move to the upper left along the first inclined guide rail 204 to disengage from the left molding block 330 of the lower mold 300. The second upper mold 500 is connected to the slider on the second inclined guide rail 205 by bolts, so that the second upper mold 500 can move to the lower left along the second inclined guide rail 205 to close the mold with the right molding block 320 of the lower mold 300, and can move to the upper right along the second inclined guide rail 205 to disengage from the right molding block 320 of the lower mold 300. Fig.12 The mold closing state is schematically shown. Figure 2 Indicates the mold opening status.

[0043] Combination Figure 2 and Figure 4 The linkage device 600 is connected to the slider on the third vertical guide rail 206 by bolts, and the linkage device 600 is respectively connected to the first power source, the first upper mold 400 and the second upper mold 500. When the linkage device 600 receives the downward pressure from the first power source, it moves downward along the third vertical guide rail 206, pushing the first upper mold 400 and the second upper mold 500 to move synchronously, and closing the mold with the lower mold 300, wherein the first upper mold 400 moves to the lower right, and the second upper mold 500 moves to the lower left. During the closing process, the downward movement of the first upper mold 400 and the second upper mold 500 stamps the metal strip into a handle shape, and the rightward movement of the first upper mold 400 and the leftward movement of the second upper mold 500 stamps out a convex and concave structure 102 (see Figure 1 ). When the linkage device 600 receives the upward pulling force from the first power source, it moves upward along the third vertical guide rail 206, pulling the first upper mold 400 and the second upper mold 500 to move upward synchronously and disengage from the lower mold 300. When the first upper mold 400 and the second upper mold 500 move upward, the first upper mold 400 moves to the left, and the second upper mold 500 moves to the right.

[0044] It can be seen that when the metal handle stamping device is in mold closing, the upper mold not only moves downward relative to the lower mold 300, but also moves left and right relative to the lower mold 300. The metal strip can be stamped into a handle shape by the downward movement of the upper mold, and the convex-concave structure 102 can be stamped out in the first section 101 of the handle 100 by the left and right movement of the upper mold. Therefore, by switching different upper molds and lower molds 300, a metal handle 100 with a convex-concave structure 102 in the first section 101 or a metal handle 100 without a convex-concave structure 102 in the first section 101 can be prepared, thereby more types of metal handles 100 can be manufactured than those of the prior art.

[0045] In addition, the metal handle stamping device connects the first power source to the two upper molds through the linkage device 600, and the linkage device 600 is slidably connected to the third vertical guide rail 206 on the frame 200, so that the two upper molds can move up and down and left and right relative to the lower mold 300 under the action of the same power source to achieve opening and closing of the molds. Therefore, when the metal handle stamping device is used to replace the handle stamping device of the existing packaging container metal handle fully automatic manufacturing and installation machine (such as CN103949886A or CN106425504A), there is no need to change the first power source, which is convenient for modifying the existing equipment.

[0046] Combination Figure 2 and Figure 4In this embodiment, the linkage device 600 includes a linkage device body 620, and the linkage device body 620 is provided with a lifting and pressing part 610 and two first connecting rods 630. The lifting and pressing part 610 is connected to the first power source, one of the two first connecting rods 630 is connected to the first upper mold 400, and the other of the two first connecting rods 630 is connected to the second upper mold 500. In this embodiment, the linkage device body 620 is slidably connected to the third vertical guide rail 206. Under the action of the first power source, the linkage device body 620 can slide straight up or down. The two first connecting rods 630 are combined with the linkage device body 620 to convert the upward or downward kinetic energy of the linkage device body 620 into power to drive the first upper mold 400 and the second upper mold 500 to move obliquely.

[0047] Reference Figure 5 In one embodiment, the first connecting rod 630 includes a first rod end joint bearing 631, a second rod end joint bearing 633 and a stud bolt 632, both ends of the stud bolt 632 are threadedly connected to the rod end of the first rod end joint bearing 631 and the rod end of the second rod end joint bearing 633, the first upper mold 400 and the second upper mold 500 are respectively provided with a first plug bolt 634, the linkage device body 620 is provided with a second plug bolt 635, the bearing end of the first rod end joint bearing 631 is movably connected to the first plug bolt 634 of one of the upper molds, and the bearing end of the second rod end joint bearing 633 is movably connected to the second plug bolt 635. In this embodiment, two rod end joint bearings are connected with stud bolts 632 to form a first connecting rod 630. The rod end joint bearings cooperate with the plug bolts to realize the connection between the first connecting rod 630 and the linkage device body 620, as well as the connection between the first connecting rod 630 and the upper mold. On the one hand, the length of the first connecting rod 630 is adjustable within a certain range. On the other hand, the influence of the shaking of the linkage device 600 on the movement of the upper mold can be reduced to a certain extent.

[0048] Combination Figure 6 , Figure 7In one embodiment, the linkage device body 620 is provided with a accommodating space 622, and a first through hole upwardly connected to the inside and outside of the accommodating space 622. The lifting and pressing portion 610 of the linkage device 600 includes a stepped rod, and the stepped rod includes a small diameter portion 613, a large diameter portion 611, and a rod shoulder portion 612. The rod shoulder portion 612 corresponds to the top end of the linkage device body 620. The small diameter portion 613 slides with the first through hole, and the lower end extends into the accommodating space 622. A limit member 621 is provided at the lower end of the small diameter portion 613 for limiting the lower end of the small diameter portion 613 within the accommodating space 622. A compression spring 623 is pressed between the limit member 621 and the bottom of the accommodating space 622. The stopper 621 can be a nut, and an external thread is set at the lower end of the small diameter part 613. After the lower end of the small diameter part 613 passes through the first through hole and extends into the accommodating space 622, the nut is connected with the external thread of the small diameter part 613, and the nut is set at the lower end of the small diameter part 613. In this embodiment, the combination of the stepped rod, the compression spring 623 and the linkage device body 620 constitutes an elastic lifting and pressing part 610. The compression spring 623 can absorb the kinetic energy at the beginning of stamping, produce a buffering effect, and make the upper die press against the metal strip more steadily.

[0049] In some embodiments, the first upper mold 400 and the second upper mold 500 have the same structure and are arranged in a left-right mirror image.

[0050] Combination Figure 2 , Fig.10 and Fig.11 In some embodiments, the first upper mold 400 and the second upper mold 500 are both composed of a mold base 510 and a mold body 520, and a double combination structure is adopted. Specifically, taking the first upper mold 400 as an example, the upper mold includes a mold base 510 and a mold body 520. The back of the mold body 520 is provided with a laterally extending connection groove 521. The mold base 510 is provided with a matching connection convex strip 511 corresponding to the connection groove 521 on the mold body 520. The connection convex strip 511 is engaged with the connection groove 521 to connect the mold body 520 to the mold base 510. The mold body 520 and the mold base 510 are also connected by connecting bolts. Compared with the use of connecting bolts alone to combine the mold body 520 and the mold base 510, in this embodiment, a double combination structure is adopted, namely a laterally extending connecting groove 521 and connecting bolts to achieve the combination of the mold body 520 and the mold base 510. The mold base 510 and the mold body 520 have a larger connecting surface, and the mold base 510 can drive the mold body 520 to move more stably.

[0051] Combination Figure 2 and Figure 3In some embodiments, the lower mold 300 includes an upper forming block 310, and the frame 200 is provided with a fourth vertical guide rail 209 on a vertical horizontal plane above the upper forming block 310. The fourth vertical guide rail 209 is slidably connected with a crimping piece 207, and the crimping piece 207 is connected to a second power source 208. The second power source 208 is installed on the frame 200, and the second power source 208 is used to drive the crimping piece 207 to approach or move away from the upper forming block 310. In this embodiment, the lower mold 300 is further provided with an upper forming block 310, and the frame 200 is provided with a fourth vertical guide rail 209, a crimping piece 207 and a second power source 208, so that before the first power source drives the first upper mold 400 and the second upper mold 500 to move downward, the second power source 208 can drive the crimping piece 207 to move downward, so that the metal strip is pressed against the upper forming block 310 and remains motionless, so as to avoid the displacement of the metal strip caused by the first upper mold 400 and the second upper mold 500 touching the metal strip.

[0052] Combination Figure 3 , Figure 8 and Fig. 9 In some embodiments, the upper forming block 310 includes a forming head 311, a forming left shoulder 313 and a forming right shoulder 314, and the rear edges of the forming left shoulder 313 and the forming right shoulder 314 are provided with a stopper 312 protruding upwards, and the bottom of the crimping piece 207 includes a crimping surface 2071 corresponding to the forming head 311, and the front edge of the crimping surface 2071 is provided with a blocking portion 2072 protruding downwards, and the blocking portion 2072 is staggered with the forming head 311 in the front-to-back direction. In this embodiment, when the first upper mold 400 and the second upper mold 500 are stamping the metal strip downwards, the stopper 312 at the rear edge of the forming left shoulder 313 and the stopper 312 at the rear edge of the forming right shoulder 314 can prevent the metal strip from moving backwards, and the blocking portion 2072 at the front edge of the crimping piece 207 can prevent the metal strip from moving forwards, which is conducive to reducing the defective rate of the handle.

[0053] Reference Fig. 9 In some embodiments, the crimping surface 2071 at the bottom of the crimping member 207 is a slope that is higher in the front and lower in the back, and the angle between the slope and the blocking portion 2072 is an acute angle. In this embodiment, the slope can also limit the metal strip to a certain extent, keeping the metal strip in the acute angle between the slope and the blocking portion 2072, which is conducive to reducing the defective rate of the handle.

[0054] In some embodiments, the left end of the left forming block 330 of the lower mold 300 and the right end of the right forming block 320 are provided with a first stamping structure, and the first upper mold 400 and the second upper mold 500 are provided with a second stamping structure that cooperates with the first stamping structure. After the first upper mold 400 is molded with the left forming block 330 of the lower mold 300, and after the second upper mold 500 is molded with the right forming block 320 of the lower mold 300, the first stamping structure and the second stamping structure cooperate to stamp out the convex-concave structure 102 in the first section 101 of the handle 100. When the first stamping structure is a convex part, the second stamping structure is a concave part, and vice versa, when the first stamping structure is a concave part, the second stamping structure is a convex part.

[0055] The metal handle punching device can be applied to a metal handle fully automatic manufacturing and installation machine, and is particularly applicable to a metal handle fully automatic manufacturing and installation machine for packaging containers. For example, the handle punching device of the device in the patent document CN103949886A or CN106425504A can be replaced with the metal handle punching device of the above embodiment to construct a new packaging container metal handle fully automatic manufacturing and installation machine.
