Description

Technical Field

[0001] This utility model relates to the field of stamping machinery technology, specifically to an automatic bottle neck punching machine for small steel cylinders. Background Technology

[0002] Small steel cylinders are special miniature steel containers with a sealed bottom at one end and a bottle-shaped mouth at the other. During production, a multi-step stamping and deformation process is used to shape the tubular mouth into a bottle-shaped mouth. This multi-step process effectively improves the deformation quality and reduces bottle mouth defects.

[0003] In existing production processes, multi-step stamping requires multiple specialized machines, resulting in complex production line layouts and high equipment investment costs. Furthermore, there is a loss of positioning accuracy when workpieces are transferred between machines, and the cumulative positioning error during transfers directly affects product dimensional accuracy, thereby increasing the defect rate and production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an automatic bottle neck punch for small steel cylinders, which solves the technical problems of complex production line layouts and loss of positioning accuracy caused by multi-step stamping relying on multiple machines in existing technologies.

[0015] Optionally, the shifting mechanism includes a guide rail, a shifting lead screw, and a motor;

Detailed Implementation

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0038] This embodiment provides an automatic bottle neck closing punch for small steel cylinders, one possible implementation of which includes:

[0039] Fixed machine base 1;

[0040] The movable machine 2 is movably installed above the fixed machine 1. A row of stamping dies 3 is set at the bottom of the movable machine 2. The stamping deformation of the small steel bottle by each stamping die increases sequentially. The movable machine 2 is installed on the fixed machine 1 through a telescopic mechanism such as a hydraulic cylinder. When the movable machine 2 is pressed down, it drives the stamping dies 3 to move down and stamp the mouth of the small steel bottle to deform.

[0041] It also includes a clamping mechanism 4, which is located on the fixed machine base 1 and is positioned corresponding to the stamping die 3. The clamping mechanism 4 includes a tightening mechanism 40, a shifting mechanism 41, and two opposing clamping plates 42. At least one clamping station 421 is provided between the two clamping plates 42 for clamping small steel cylinders. The two clamping plates 42 are connected by the tightening mechanism 40 and can be clamped or loosened relative to each other. The tightening mechanism 40 is installed on the shifting mechanism 41 and can reciprocate along the arrangement direction of the stamping die 3.

[0042] In the above embodiment, the working process is as follows: the clamping mechanism 4 clamps a small steel cylinder blank, initially located below the first stamping die 3. The movable machine platform 2 presses down, driving the stamping die 3 to stamp and deform the small steel cylinder blank. After completion, the movable machine platform 2 moves up and detaches from the small steel cylinder blank. Then, the clamping mechanism 4 clamps the small steel cylinder blank and moves it within the spacing range of one stamping die 3, entering the area below the next stamping die 3. The above process is repeated. After multiple stamping steps, the small steel cylinder blank becomes a finished small steel cylinder. At this time, the loosening mechanism 40 releases the two clamping plates 42, removes the finished small steel cylinder, and then the shifting mechanism 41 moves the clamping plates 42 back to the initial position and re-clamps a small steel cylinder blank to repeat the above steps, completing the processing of the next small steel cylinder blank.

[0043] The automatic bottle neck punching machine for small steel cylinders described in the above embodiment has significant advantages. By setting up a row of stamping dies, the movable machine base drives the stamping dies to press down, and the shifting mechanism 41 drives the small steel cylinder blank to move, enabling multi-step stamping of the small steel cylinder blank step by step, so that the deformation of the bottle neck gradually changes, improving product quality. The clamping mechanism, in conjunction with the shifting mechanism, can accurately move the small steel cylinder blank, achieving continuous and efficient processing. The tensioning mechanism facilitates the loading and unloading of finished products, and the overall automation level is high, reducing manual operation, improving production efficiency, reducing labor intensity, and completing the entire stamping process on a single machine.

[0044] In one possible process design, the stamping is completed in five steps. There are five stamping dies 3. Along the arrangement direction of the stamping dies 3, the shape of the die cavity gradually changes to match the bottle mouth, and the stamping deformation of the bottle mouth is as follows: Figure 8 As shown. At both ends of the clamping mechanism 4, there are also a feeding machine 6 and a discharging machine 7. The feeding machine 6 is used to put the small steel bottle stamping billet into the clamping mechanism 4, and the discharging machine 7 is used to receive the finished small steel bottle stamping product.

[0045] In this embodiment, the tensioning mechanism 40 includes a mounting block 404, a sliding block 403, and a power mechanism 402;

[0046] Two clamping plates 42 are respectively and fixedly mounted on two mounting blocks 404. The two mounting blocks 404 are respectively and slidably mounted on sliding blocks 403. A special sliding groove can be provided in the sliding blocks 403. The relative distance between the two sliding blocks 403 is controlled by the power mechanism 402. When the two sliding blocks 403 move relative to each other, they clamp the small steel cylinder; when they move in opposite directions, they release the small steel cylinder. Two sets of tightening and loosening mechanisms 40 can be set, located at both ends of the clamping plates 42 respectively, to synchronously control the movement state of both ends of the two clamping plates 42.

[0047] Specifically, in one possible implementation, the power mechanism 402 includes two telescopic power sources, each controlling the sliding amount of the two mounting blocks 404 relative to the sliding block 403. For example... Figure 4 As shown, a telescopic cylinder is provided on the back side of each of the two mounting blocks 404, and the distance between the two mounting blocks 404 is controlled by the two telescopic cylinders.

[0048] In another possible implementation, such as Figure 5 As shown, the power mechanism 402 includes a motor and a bidirectional lead screw 4021. The two ends of the bidirectional lead screw 4021 have opposite thread directions and are threadedly engaged with two mounting blocks 404 respectively. The bidirectional lead screw 4021 is driven by the motor. When the motor drives the bidirectional lead screw 4021 to rotate, the two mounting blocks 404 will have synchronous and opposite motion states, thereby causing the two clamping plates 42 to simultaneously loosen or clamp.

[0049] In another possible implementation, the power mechanism 402 includes a telescopic power source and a bidirectional lead screw. The two ends of the bidirectional lead screw have opposite thread directions and are threadedly engaged with two mounting blocks 404 respectively. The bidirectional lead screw is also rotatably mounted on a sliding block 403. The telescopic power source controls the sliding amount of one of the mounting blocks 404 relative to the sliding block 403. For example, the telescopic power source is a cylinder. By extending, it pushes one of the mounting blocks 404 to move. Since the mounting block 404 is threadedly engaged with the bidirectional lead screw, the movement of the mounting block 404 will cause the bidirectional lead screw to rotate. At the other end of the bidirectional lead screw, the rotation of the bidirectional lead screw will drive the other sliding block 403 to move, thereby forming a synchronous clamping or releasing action.

[0050] In this embodiment, the shifting mechanism 41 includes a guide rail 411, a shifting screw 412, and a motor. The guide rail 411 is fixedly installed on the fixed machine base 1 along the arrangement direction of the stamping die 3, and the sliding block 403 is slidably installed on the guide rail 411. The shifting screw 412 is parallel to the guide rail 411 and threadedly engaged with the sliding block 403. The shifting screw 412 is driven by the motor. When the motor drives the shifting screw 412 to rotate, the sliding block 403 will move along the guide rail 411, and the clamping mechanism 4 installed on the sliding block 403 will also move along the guide rail 411, thereby moving the small steel cylinder blank on the clamping plate 42 to align with different stamping dies 3 and be stamped and deformed.

[0051] In this embodiment, a support mechanism 5 is also included. The support mechanism 5 is fixedly installed on the fixed machine base 1 and located below the clamping plate 42. Its position and number correspond to the stamping die 3. The support mechanism 5 includes a base 50 and clamping seats 51. The base 50 is fixedly installed on the fixed machine base 1 and has a notch along the arrangement direction of the stamping die 3. When the clamping plate 42 clamps the small steel cylinder blank and moves along the arrangement direction of the stamping die 3, the bottom of the small steel cylinder blank can pass through the notch of the base 50. At least two clamping seats 51 are installed opposite each other on the inner side of the base 50 and are all slidably engaged with the base 50. The sliding distance is controlled by a telescopic mechanism. Figure 6 As shown. The telescopic mechanism is a telescopic power source (cylinder) or airbag (not shown) located between the base 50 and the clamping seat 51. The two clamping seats 51 can clamp the bottom of the small steel cylinder blank. Even if the two clamping seats 51 on the upper part of the small steel cylinder blank separate and lose their clamping effect on the small steel cylinder blank, the small steel cylinder blank can remain in its original position without falling off.

[0052] In this embodiment, based on the above embodiment, the telescopic mechanism is an elastic element 52, such as a spring, disposed between the base 50 and the clamping seat 51. Figure 7As shown. Under the elastic force of the elastic element 52, initially, the two clamping seats 51 will be in an extended state, which can hold the bottom of the small steel cylinder blank. When the two clamping seats 51 clamp the upper part of the small steel cylinder blank and move from the outside of the two clamping seats 51 into the space between the two clamping seats 51, under the action of the extrusion force, the bottom of the small steel cylinder blank will be able to squeeze the two clamping seats 51. The two clamping seats 51 will retract and open against the elastic force, and the bottom of the small steel cylinder blank will enter the space between the two clamping seats 51 and be clamped. At this time, even if the two clamping plates 42 are loosened, the small steel cylinder blank can be fixed in place and will not fall off. When the two clamping seats 51 clamp the upper part of the small steel cylinder blank and move from the middle of the two clamping seats 51 to the outside of the two clamping seats 51, under the action of the extrusion force, the bottom of the small steel cylinder blank will be able to squeeze the two clamping seats 51. The two clamping seats 51 overcome the elastic force, retract and open, and the bottom of the small steel cylinder blank leaves between the two clamping seats 51 and can enter the next stamping station.

[0053] The beneficial effect of the above embodiments is that they can increase the continuity of the production process. Specifically, five sets of stamping dies and five sets of support mechanisms 5 can be set simultaneously, and five clamping stations are correspondingly set on the two clamping seats 51.

[0054] Specifically, clamping plate 42 in Figure 1 In the state of first moving one position to the left, the first small steel cylinder blank is put into the clamping position of the leftmost clamping position of the two clamping plates 42. After the clamping plates 42 are clamped, move one position to the right. The first small steel cylinder blank is aligned with the first stamping die 3. The stamping die 3 moves down to stamp and then moves up.

[0055] Then, clamping plate 42 is released. Due to the action of support mechanism 5, the first small steel cylinder blank will remain in place and will not fall. With clamping plate 42 in the released state, it moves one position to the left. Then, the second small steel cylinder blank is placed into the leftmost clamping position of the two clamping plates 42. Subsequently, the two clamping plates 42 clamp and move one position to the right. The first small steel cylinder blank enters the second stamping die 3 position, and the second small steel cylinder blank enters the first stamping die 3 position. The stamping die 3 moves down for stamping and then moves up.

[0056] Next, clamping plate 42 is released again, leaving the first and second small cylinder blanks in their original positions. Clamping plate 42 moves one position to the left while released, and then the third small cylinder blank is placed into the leftmost clamping position of the two clamping plates 42. The two clamping plates 42 then clamp and move one position to the right, allowing the first small cylinder blank to enter the third stamping die 3 position, the second small cylinder blank to enter the second stamping die 3 position, and the third small cylinder blank to enter the first stamping die 3 position. The stamping die 3 moves down for stamping and then moves up.

[0057] Next, clamping plate 42 is released again, leaving the first, second, and third small cylinder blanks in their original positions. Clamping plate 42 moves one station to the left while released, then the fourth small cylinder blank is placed into the leftmost clamping position of the two clamping plates 42. The two clamping plates 42 then clamp and move one station to the right. The first small cylinder blank enters the fourth stamping die 3 station, the second small cylinder blank enters the third stamping die 3 station, the third small cylinder blank enters the second stamping die 3 station, and the fourth small cylinder blank enters the first stamping die 3 station. The stamping die 3 moves down for stamping and then moves up.

[0058] Next, clamping plate 42 is released again, leaving the first, second, third, and fourth small steel cylinder blanks in their original positions. Clamping plate 42 moves one station to the left while released, then the fifth small steel cylinder blank is placed into the leftmost clamping station of the two clamping plates 42. The two clamping plates 42 then clamp and move one station to the right. The first small steel cylinder blank enters the fifth stamping die 3 station, the second small steel cylinder blank enters the fourth stamping die 3 station, the third small steel cylinder blank enters the third stamping die 3 station, the fourth small steel cylinder blank enters the second stamping die 3 station, and the fifth small steel cylinder blank enters the first stamping die 3 station. The stamping die 3 moves down for stamping and then moves up.

[0059] Finally, clamping plate 42 is released again, and the first, second, third, fourth, and fifth small steel cylinder blanks remain in their original positions. Clamping plate 42 moves one station to the left while in the released state, and then the sixth small steel cylinder blank is placed into the leftmost clamping position of the two clamping plates 42. Subsequently, the two clamping plates 42 clamp and move one station to the right. The first small steel cylinder blank falls off after leaving the fifth stamping die 3 and leaves the production line. (See reference...) Figure 3 Holes are set at corresponding positions on the machine body. The second small steel cylinder blank enters the fifth stamping die station 3, the third small steel cylinder blank enters the fourth stamping die station 3, the fourth small steel cylinder blank enters the third stamping die station 3, the fifth small steel cylinder blank enters the second stamping die station 3, and the sixth small steel cylinder blank enters the first stamping die station 3. The stamping die 3 moves down for stamping and then moves up.

[0060] Repeating the above process, the entire production line can achieve a continuous, rhythmic operation. The beneficial effects of the above embodiment are significant. By setting up five sets of stamping dies and five sets of support mechanisms, along with the design of five clamping stations on two clamping seats, a high degree of continuity in the production process is achieved. In the cycle of gradual movement and clamping / releasing of the clamping plates, small steel cylinder preforms can orderly enter each stamping die station, complete stamping, and continue moving, ultimately achieving a continuous, rhythmic operation. This design not only improves production efficiency but also ensures that each preform is precisely processed, reduces manual intervention, lowers production costs, and improves overall production quality.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
