[0019] After adopting the above technical solution, the beneficial effects of the utility model are:

[0020] 1. When the present application is used, the cylindrical can blank that has not been expanded and ribbed is first sent to the expansion die, so that the two expansion dies are both contained in the cylindrical can blank, and the two rib dies are located on the outside of the cylindrical can blank. By driving the transmission rod of the expansion die to move, the wedge block is driven to rise and fall vertically relative to the expansion die, so that the two expansion dies are spread apart, that is, the expansion dies move away from each other, thereby completing the expansion of the cylindrical can blank. By driving the transmission rod of the embossing die, the limiting ring of the embossing die is driven to descend vertically, that is, the embossing block is driven to descend vertically relative to the embossing die. At this time, with the cooperation of the roller on the embossing die and the guide surface on the embossing block, the two embossing dies move toward the direction close to the expansion die, so that the inner sides of the two embossing dies are respectively in contact with the side walls of the cylindrical can embryo. At this time, the two expansion dies respectively support the two sides of the inner wall of the cylindrical can embryo, when the two embossing dies are respectively in contact with the two outer walls of the cylindrical can embryo, the two embossing dies cooperate with the two expansion dies to complete the embossing of the cylindrical can embryo.

[0021] 2. The present application can synchronously drive the expansion die transmission rod and the rib pressing die transmission rod to rise and fall synchronously through the setting of the synchronous pressing plate, so that the wedge block and the limit ring are synchronously lowered, so that the wedge block drives the two expansion dies to open while the limit ring is also driving the rib pressing block to contact the rib pressing die. Due to the setting of the vertical section and the inclined section of the guide surface, when the wedge block drives the two expansion dies to open, the roller outside the rib pressing block abuts against the vertical section on the guide surface. At this time, the positions of the two rib pressing blocks remain unchanged. After the expansion die completes the expansion action of the cylindrical can blank, the expansion die transmission rod and the rib pressing die transmission rod are continued to be driven downward by the synchronous pressing plate, so that the roller outside the rib pressing block abuts against the inclined section on the guide surface, thereby driving the two rib pressing dies to move in a direction close to each other, and then completing the rib pressing action on the cylindrical can blank, thereby accelerating production efficiency, reducing production costs, having strong practicality, and having good market promotion prospects.

[0022] 3. The present application guides the outer mold for embossing by the cooperation between the linear guide rail, the first slider and the second slider, so that the outer mold for embossing can stably move toward or away from the expansion die, thereby ensuring the embossing effect on the metal can blank and reducing the production cost.

[0023] 4.

The structure is simple, easy to obtain, and the production cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0035] This embodiment relates to a metal can squaring and rib pressing integrated forming device, which is used to squaring and rib pressing a cylindrical metal can blank, so as to obtain a metal square can that meets the requirements. Figure 1 and Figure 2 , which includes a positioning seat 1, a fixing seat 2, an expansion die mechanism 3 and a rib pressing die mechanism 4. The positioning seat 1 and the fixing seat 2 are both fixedly connected to an external frame (not shown in the figure), the positioning seat 1 is arranged in a rectangular parallelepiped shape, the fixing seat 2 is arranged in a cube shape, the fixing seat 2 is located directly below the positioning seat 1, and there is a gap between the fixing seat 2 and the positioning seat 1.

[0036] The expansion die mechanism 3 is located directly below the fixed seat 2. Specifically, the expansion die mechanism 3 includes two expansion die 31 vertically arranged on the bottom side of the fixed seat 2, a wedge block 32 that can be raised and lowered between the two expansion die 31, and an expansion die transmission rod 33 for driving the wedge block 32 to vertically rise and fall relative to the expansion die 31, wherein the two expansion die 31 are arranged opposite to each other, the centers of the two expansion die 31 are on the same vertical straight line as the centers of the positioning seat 1 and the fixed seat 2, the two expansion die 31 are slidably arranged on the bottom side of the fixed seat 2, and the two expansion die 31 can move relative to the fixed seat 2 along the length direction of the positioning seat 1 in the direction of approaching or moving away from each other, the wedge block 32 is slidably arranged between the two expansion die 31, and the two sides of the wedge block 32 are respectively slidably matched with the two expansion die 31, the expansion die transmission rod 33 is vertically arranged, and the bottom end of the expansion die transmission rod 33 passes through the positioning seat 1 and the fixed seat 2 and is fixedly connected to the wedge block 32. When the expansion die transmission rod 33 drives the wedge block 32 to vertically descend relative to the expansion die 31, the wedge block 32 can open the two expansion dies 31, that is, the two expansion dies 31 move away from each other to complete the expansion action of the metal can blank.

[0037] Reference Figure 4 and Figure 5 and Figure 6 The rib pressing die mechanism 4 is located outside the expansion die mechanism 3. Specifically, the rib pressing die mechanism 4 includes two rib pressing dies 41 symmetrically arranged outside the expansion die 31, a rib pressing block 42 rollingly matched with the outside of the rib pressing die 41, a limit ring 43 fixedly connected to the rib pressing block 42, and a rib pressing die transmission rod 44 for driving the limit ring 43 to vertically descend, wherein the two rib pressing dies 41 are symmetrically arranged outside the two expansion die 31, and the two rib pressing dies 41 can move in the direction of approaching or moving away from the expansion die 31. There are two rib pressing blocks 42, and the two rib pressing blocks 42 correspond to the two rib pressing dies 41 respectively, and the two rib pressing blocks 42 are respectively located on the side of the two rib pressing dies 41 away from the expansion die 31. A guide surface 421 is provided on the side of the rib pressing block 42 facing the rib pressing die 41, and the guide surface 421 is respectively a vertical section and an inclined section from top to bottom, and a roller 45 rollingly matched with the guide surface 421 is provided on the outside of the rib pressing die 41. The limiting ring 43 is arranged around the outside of the two beading blocks 42, and the two beading blocks 42 are symmetrically arranged on both sides of the limiting ring 43. The bottom end of the beading die transmission rod 44 passes through the fixed seat 2 and is fixedly connected to the limiting ring 43. When the beading die transmission rod 44 drives the limiting ring 43 to vertically descend relative to the beading die 41, the beading block 42 is driven to vertically descend, and the beading die 41 is driven to move toward the direction of the expansion die 31 under the cooperation of the roller 45 and the guide surface 421, that is, the two beading dies 41 move toward each other, thereby completing the beading action on the metal can blank.

[0038] In addition, it should be noted that the moving directions of the two expansion dies 31 and the moving directions of the two beading dies 41 are perpendicular to each other, so that the beading dies 41 can stably perform beading action on the metal can blank.

[0039] It can be understood that, when working, the cylindrical metal can blank that needs to be expanded and ribbed is first sent to the expansion die 31, and the two expansion dies 31 are placed in the metal can blank, and the two rib embossing dies 41 are respectively located on both sides of the metal can blank. At this time, the wedge block 32 is driven to vertically descend relative to the expansion die 31 by the expansion die transmission rod 33, so that the wedge block 32 opens the two expansion dies 31, that is, the two expansion dies 31 move in directions away from each other, thereby realizing the expansion of the metal can blank, and the limit ring 43 is driven to vertically descend by the rib embossing die transmission rod 44, driving the rib embossing block 42 to vertically descend. At this time, with the cooperation of the guide surface 421 and the roller 45, the two rib embossing dies 41 are driven to move in a direction close to the expansion die 31 at the same time, that is, the two rib embossing dies 41 move in a direction close to each other, so that the rib embossing die 41 can perform rib embossing on the metal can blank.

[0040] Further, refer to Figure 2 , Figure 3 A guide block 311 is provided on the opposite side of the two expansion dies 31. The two guide blocks 311 are symmetrically arranged. A first inclined surface 312 inclined downward is provided on the side facing each other of the two guide blocks 311. Second inclined surfaces 321 matching the first inclined surfaces 312 are provided on both sides of the wedge block 32.

[0041] By setting the guide block 311, the first inclined surface 312 on the guide block 311 and the second inclined surface 321 on the wedge block 32, when the wedge block 32 is driven by the expansion die transmission rod 33 to vertically descend relative to the expansion die 31, the wedge block 32 can open the two expansion dies 31, that is, the two expansion dies 31 move away from each other under the action of the wedge block 32, so that the two expansion dies 31 can expand the metal can blank.

[0042] Furthermore, the number of guide blocks 311 and second inclined surfaces 321 is two groups, wherein the two groups of guide blocks 311 are symmetrically arranged at the upper and lower ends of the expansion die 31, and the two groups of second inclined surfaces 321 are symmetrically arranged at the upper and lower ends of the wedge block 32. Through the above arrangement, when the wedge block 32 is driven by the expansion die transmission rod 33 to vertically rise and fall relative to the expansion die 31, the upper and lower ends of the expansion die 31 can be opened by the wedge block 32, thereby ensuring the expansion effect of the expansion die 31 on the metal can blank and ensuring the quality of the finished product.

[0043] Furthermore, a through hole 21 is provided in the middle of the fixed seat 2, and the bottom end of the expansion die transmission rod 33 passes through the through hole 21 and is connected to the wedge block 32. The top ends of the two expansion dies 31 pass upward through the through hole 21 and protrude from the top surface of the fixed seat 2. The top ends of the two expansion dies 31 are provided with connecting shafts 313, and both ends of the connecting shafts 313 are provided with rolling bearings 314. The rolling bearings 314 are rollingly connected to the top surface of the fixed seat 2, and a limiting groove 22 for limiting the rolling trajectory of the rolling bearings 314 is provided on the fixed seat 2.

[0044] It can be understood that when the expansion die transmission rod 33 drives the wedge block 32 to vertically descend relative to the expansion die 31, the two expansion dies 31 are driven to move in a direction away from each other. At this time, the two expansion dies 31 can stably move in a direction away from each other through the setting of the connecting shaft 313 and the rolling bearing 314. At the same time, the rolling trajectory of the rolling bearing 314 is limited by the limiting groove 22, that is, the movement trajectory of the two expansion dies 31 is limited, thereby avoiding the expansion dies 31 from deviating when moving in a direction away from each other, and further ensuring the expansion effect of the expansion die 31 on the metal can blank.

[0045] Furthermore, the two expansion dies 31 are provided with tension springs 34, and the two expansion dies 31 are provided with positioning grooves for positioning the tension springs 34. The tension springs 34 are used to automatically reset the two expansion dies 31 after being stretched apart by the wedge block 32. In this embodiment, there are two tension springs 34, and the two tension springs 34 are cooperatively sleeved on the outside of the two expansion dies 31.

[0046] It can be understood that when the two expansion dies 31 are stretched apart by the wedge block 32, that is, the two expansion dies 31 move away from each other, the tension spring 34 is in a stretched state. When the protrusion on the wedge block 32 is separated from the guide block 311 on the expansion die 31, the tension spring 34 automatically recovers, driving the two expansion dies 31 to move toward each other, so that the two expansion dies 31 can automatically reset to the initial state to facilitate the next expansion action.

[0047] Further, refer to Figure 4 and Figure 5 and Figure 6The embossing die 41 includes an inner embossing die 411 and an outer embossing die 412. The upper part of the inner embossing die 411 is fixedly connected to the bottom of the fixed seat 2. The side of the inner embossing die 411 away from the outer embossing die 412 is always in contact with the side wall of the wedge block 32 other than the second inclined surface 321 and can slide relatively. The outer embossing die 412 is located on the outer side of the inner embossing die 411. A gap is left between the outer embossing die 412 and the inner embossing die 411. The outer embossing die 412 can move toward or away from the inner embossing die 411. When the metal can blank is subjected to the square expansion and embossing action, the metal can blank is located in the gap between the outer embossing die 412 and the inner embossing die 411, so that the inner embossing die 411 abuts against the inner wall of the metal can blank, and the outer embossing die 412 abuts against the outer wall of the metal can blank.

[0048] The roller 45 is fixedly arranged on the upper part of the side of the beading outer mold 412 away from the beading inner mold 411, and the beading inner mold 411 is provided with a beading groove on the side facing the beading outer mold 412, and the beading outer mold 412 is provided with a beading convex strip matching the beading groove on the side facing the beading inner mold 411, and the beading convex strip and the beading groove are respectively in contact with the outer wall and the inner wall of the metal can blank and cooperate to bead the metal can blank.

[0049] Furthermore, the rib block 42 is integrally formed with a first flange 422 and a second flange 423, the first flange 422 and the second flange 423 are both located on the side of the rib block 42 away from the rib mold 41, and the first flange 422 is located at the top of the rib block 42, and the second flange 423 is located in the middle of the rib block 42, and there are two limiting rings 43, which are fixedly connected to the first flange 422 and the second flange 423 by bolts respectively.

[0050] By setting the first convex edge 422 and the second convex edge 423, the connection between the limit ring 43 and the rib pressing block 42 is more firmly established, so that when the rib pressing die transmission rod 44 drives the limit ring 43 to rise and fall, the rib pressing block 42 can stably rise and fall vertically relative to the rib pressing die 41.

[0051] Furthermore, the embossing mold mechanism 4 also includes two linear guide rails 46, and the two linear guide rails 46 are stacked and arranged at the two ends of the bottom side of the embossing mold 41. The two ends of the bottom side of the two embossing molds 41 are provided with a first slider 47 and a second slider 48 that slide and cooperate with the linear guide rails 46, and a spring 49 is provided between the two first sliders 47 and the two second sliders 48, so that the two embossing molds 41 can automatically reset after moving toward the direction close to the expansion mold 31.

[0052] In addition, refer to Figure 7In this embodiment, the bottom side width of the rib block 42 is smaller than the gap between the two linear guide rails 46, that is, when the rib mold transmission rod 44 drives the rib block 42 to vertically descend, the bottom side of the rib block 42 can enter the gap between the first slider 47 and the second slider 48, and a limit block 5 is provided between the first slider 47 and the second slider 48 for limiting the downward position of the rib block 42.

[0053] It can be understood that the linear guide 46 cooperates with the first slider 47 and the second slider 48 on the embossing die 41 to guide the two embossing dies 41, so that the two embossing dies 41 can stably move in the direction of approaching or away from the expansion die 31, so that the two embossing dies 41 can stably perform embossing on the metal can blank. At the same time, through the setting of the spring 49, after the two embossing dies 41 complete the embossing, when the embossing die transmission rod 44 drives the limit ring 43 and the embossing block 42 to rise vertically, the two embossing dies 41 can automatically move to a position away from each other, that is, the two embossing dies 41 can automatically reset, so as to facilitate the next embossing action, and through the setting of the limit block 5, the downward position of the embossing block 42 is limited, so as to achieve precise control of the travel of the two embossing dies 41 moving in the direction of approaching each other, and further ensure the embossing effect of the embossing die 41.

[0054] Furthermore, there are two embossing die transmission rods 44, which are symmetrically arranged on both sides of the expansion die transmission rod 33. It should be noted that the bottom end of the embossing die transmission rod 44 passes through the center of the positioning seat 1 and the fixing seat 2 and is fixedly connected to the wedge block 32. The two embossing die transmission rods 44 pass through the fixing seat 2 and are respectively fixedly connected to both sides of the limit ring 43. The tops of the embossing die transmission rods 44 and the expansion die transmission rods 33 are provided with a synchronous pressing plate 6 for driving the embossing die transmission rods 44 and the expansion die transmission rods 33 to rise and fall synchronously. In addition, in the specific implementation process, a driving mechanism can be arranged above the synchronous pressing plate 6, and the driving mode of the driving mechanism includes but is not limited to cam mechanical cooperation, cylinder drive, etc., so as to drive the synchronous pressing plate 6 to vertically descend through the driving mechanism, thereby driving the expansion die transmission rod 33 and the embossing die transmission rod 44 to descend synchronously.

[0055] As can be understood, the synchronous pressing plate 6 is driven vertically downward by the driving mechanism, driving the expansion die transmission rod 33 and the embossing die transmission rod 44 to descend simultaneously, causing the wedge block 32 and the limit ring 43 to descend simultaneously, thereby causing the wedge block 32 and the embossing block 42 to descend simultaneously. When the wedge block 32 drives the two expansion dies 31 to move in a direction away from each other, at this time, the roller 45 on the embossing outer die 412 abuts against the vertical section on the inner guide surface 421 of the embossing block 42. After the two expansion dies 31 complete the expansion action on the metal can blank, the expansion die transmission rod 33 and the embossing die transmission rod 44 continue to descend vertically under the action of the driving mechanism and the synchronous pressing plate 6, driving the embossing block 42 to continue to descend vertically, causing the roller 45 on the embossing outer die 412 to abut against the inclined section of the guide surface 421 on the embossing block 42, thereby driving the two embossing outer dies 412 to move in a direction close to each other, thereby realizing the embossing action on the metal can blank after the expansion is completed.

[0056] Furthermore, three copper sleeves 7 are fixedly arranged on the positioning seat 1, and the three copper sleeves 7 correspond to the two embossing die transmission rods 44 and the expansion die transmission rod 33 one by one, and the three copper sleeves 7 guide the two embossing die transmission rods 44 and the expansion die transmission rod 33 one by one.

[0057] By setting the copper sleeve 7, the two bead pressing die transmission rods 44 and the expansion die transmission rod 33 can be stably lifted and lowered vertically, thereby ensuring the expansion and bead pressing effects on the metal can blank.

[0058] In addition, in order to achieve the reset of the expansion die transmission rod 33 and the embossing die transmission rod 44, a reset spring 8 is arranged outside the expansion die transmission rod 33 and the embossing die transmission rod 44. The reset spring 8 is vertically arranged, and one end of the reset spring 8 abuts against the bottom side of the positioning plate, and the other end of the reset spring 8 abuts against the top surface of the copper sleeve 7.

[0059] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
