Technical Field

[0001] This invention relates to a molding machine and a molding method, specifically a packing buckle and a method for manufacturing the packing buckle. Background Technology

[0002] In the product packaging industry, strapping and buckles are an alternative to traditional nylon ropes and manual strapping. They rely on the interaction between the tension of the strapping on the buckle legs and the binding force of the buckle ring on the buckle legs to achieve the packaging task. They can be used without any tools and have the advantages of simple operation, easy carrying and reusability. Therefore, steel strapping and buckles are widely used in the product packaging industry.

[0003] The current process for processing packing buckles is as follows: the operator first uses a straightening mechanism to straighten the rolls one by one.

[0004] The metal wire is unwound and straightened. Then, the operator uses a cutting mechanism to cut the straightened metal wire into sections of the required length. The operator then moves the cut metal wire sections to a bending mechanism in another work environment and bends them into C-shaped buckles. Another section of metal wire is then inserted into the C-shaped buckle and bent together to prevent the C-shaped buckle from falling off, thus forming a packing buckle.

[0005] The production process of the aforementioned packing buckle is too complicated and the processing efficiency is slow. Therefore, this invention applies for a packing buckle and a method for manufacturing the packing buckle to solve the above problems. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-9 The present invention provides a technical solution: a packing buckle and a method for manufacturing the packing buckle, comprising a C-shaped buckle 1 and a steel strap buckle 2. One end of the steel strap buckle 2 passes through the inner side of the opening formed by the C-shaped buckle 1. The end of the steel strap buckle 2 passing through the C-shaped buckle 1 is bent to form a U-shaped clamp 201 for clamping the C-shaped buckle 1. The steel strap buckle 2 is stamped to form a recess 46 for clamping the C-shaped buckle 1 on the side of the C-shaped buckle 1 away from the U-shaped clamp 201. The U-shaped clamp 201 and the recess 46 are respectively located at both ends of the C-shaped buckle 1 for limiting and fixing the C-shaped buckle 1.

[0039] The manufacturing method of the packing buckle includes the following steps:

[0040] Step 1: Feed the first steel strip 3 for manufacturing steel buckle 2 and the second steel strip 4 for manufacturing C-shaped buckle 1 into the bending mechanism from two directions respectively, and transport the first steel strip 3 and the second steel strip 4 to the bending area so that the second steel strip 4 is cross-overly stacked on top of the first steel strip 3.

[0041] Step 2: Cut the first steel strip 3 to a fixed length;

[0042] Step 3: Use a bending mechanism to punch the first steel strip 3 and the second steel strip 4, so that the ends of the first steel strip 3 and the second steel strip 4 located in the punching area 6 are both bent downwards, and at the same time, the first steel strip 3 is punched to form a concave part 46;

[0043] Step 4: Using a bending mechanism, bend the overlapping area of ​​the first steel strip 3 and the second steel strip 4 again at the bending point in Step 3, so that the bending point of the second steel strip 4 is tightened around the bottom of the first steel strip 3 to form a C-shaped buckle 1, and the bending point of the first steel strip 3 is tightened around the bottom of the C-shaped buckle 1.

[0044] Specifically, the bending mechanism includes a base plate 44 and a stamping assembly and a bending assembly disposed on the base plate 44. The stamping assembly and the bending assembly are disposed opposite to each other. The base plate 44 is provided with a first feed port 7 for the first steel strip 3 to pass through to the stamping area 6. A long plate 8 is disposed on the back of the base plate 44. A guide roller 9 for pressing and centering the first steel strip 3 is disposed on the long plate 8. The guide roller 9 conveys the first steel strip 3 from the first feed port 7 to the stamping area 6. The conveying method of the first steel strip 3 is the same as that of the existing method, so it will not be described in detail. A hydraulic shear 10 for cutting the first steel strip 3 is also disposed on the long plate 8. The cutting method is also... Similar to existing methods, a positioning block 11 is provided on the substrate 44, and a second feed port 12 for the second steel strip 4 to enter the stamping area 6 is provided on the positioning block 11. A long plate 8 is also provided on one side of the substrate 44, and a guide roller 9 for conveying the second steel strip 4 is also provided on the long plate 8. The conveying method is the same as the conveying method of the first steel strip 3, which are all existing technologies, so they will not be described in detail. It should be noted that the horizontal height of the second feed port 12 is higher than the horizontal height of the first feed port 7 by more than one steel strip thickness, so that when the first steel strip 3 and the second steel strip 4 enter the stamping area 6, they can form a stacked effect.

[0045] The stamping assembly includes a first hydraulic cylinder 13 and a stamping plate 14 fixed to the output end of the first hydraulic cylinder 13;

[0046] The bending assembly includes a second hydraulic cylinder 15 located below the first hydraulic cylinder 13 and a support block 16 fixed to the output end of the second hydraulic cylinder 15. The bottom of the stamping plate 14 is provided with a stamping cavity 17 opposite to the support block 16. Before the first steel strip 3 and the second steel strip 4 enter the stamping area 6, the second hydraulic cylinder 15 preferentially drives the support block 16 to move upward, so that the top end face of the support block 16 is flush with the bottom inner wall of the first feed port 7. After the first steel strip 3 enters the stamping area 6, it is located on the support block 16, and after the second steel strip 4 enters the stamping area 6, it is stacked on the first steel strip 3. After the support block 16 enters the stamping cavity 17, there is a gap of more than one steel strip thickness between the inner wall of the stamping cavity 17 and the support block 16. Thus, after the stamping plate 14 moves downward and the support block 16 enters the stamping cavity 17, the ends of the first steel strip 3 and the second steel strip 4 that extend beyond the support block 16 are bent downward. In this embodiment, the steel strip is bent at a ninety-degree angle.

[0047] Specifically, the support block 16 has a groove 18 at the top, and an extension plate 20 is provided in the stamping cavity 17 directly above the groove 18. The bottom of the extension plate 20 has a stamping rod 19. After the support block 16 enters the stamping cavity 17, the extension plate 20 moves down with the stamping plate 14 and punches the first steel strip 3 into the groove 18, thereby forming a recess 46.

[0048] Specifically, a limiting plate 21 is provided on one side of the stamping area 6 of the substrate 44. The limiting plate 21 is located on the side of the stamping area 6 away from the positioning block 11. The end faces of the limiting plate 21 and the positioning block 11 that are close to each other coincide with the two end faces of the stamping plate 14. In this way, during the downward movement of the stamping plate 14, the outer wall of one side of the stamping plate 14 moves downward against the outer wall of the positioning block 11, thereby shearing the second steel strip 4. As the stamping plate 14 continues to move downward, it will bend the sheared second steel strip 4 downward. It should be noted that the distance between the support block 16 and the limiting plate 21 is the same as the distance between the support block 16 and the positioning block 11, so that the second steel strip 4 is at the same distance on both sides of the support block 16 after being sheared.

[0049] Specifically, the bending mechanism also includes first bending blocks 22 symmetrically arranged on both sides of the stamping area 6. The first bending blocks 22 are located below the limiting plate 21 and the positioning block 11. The support block 16 has a first linkage structure on both sides that drives the first bending blocks 22 on both sides to slide towards each other or away from each other. After the second steel strip 4 is bent downward, the first bending blocks 22 on both sides are driven to slide towards each other to achieve a second bend at the bend of the second steel strip 4, thereby covering the first steel strip 3. In this embodiment, the first bending blocks 22 slide to bend the bend of the second steel strip 4 again by ninety degrees. The base plate 44 is provided with a first slide rail 23, and the first bending blocks 22 are slidably arranged on the first slide rail 23.

[0050] Specifically, the first linkage structure includes first extension plates 25 symmetrically arranged on both sides of the support block 16 and a first U-shaped frame 24 disposed above the first extension plates 25 on both sides. The first U-shaped frame 24 includes first side rods 241 symmetrically arranged on the front and rear sides of the first extension plates 25 and a first connecting rod 242 connecting the two first side rods 241. The first bending block 22 is provided with a first sliding area 26 for the first side rods 241 to slide and a first V-shaped groove 27 for the first connecting rod 242 to slide. By the downward movement of the support block 16 This will cause the first side rod 241 to slide within the first sliding area 26. At the same time, the first connecting rod 242 will drive the first bending block 22 to slide on the first slide rail 23 through cooperation with the first V-groove 27, thereby realizing the bending of the second steel strip 4. It should be noted that the first bending block 22 is provided with a first notch 28 on the side near the support block 16. When the support block 16 moves down and the first bending block 22 moves horizontally to bend, the first notch 28 can prevent the first bending block 22 from hitting the support block 16 and getting stuck.

[0051] Specifically, a fixing plate 29 is horizontally provided on the substrate 44, and a second bending block 30 is slidably provided on the fixing plate 29. A second linkage structure is provided on the support block 16 to drive the second bending block 30 to slide closer to or further away from the stamping area 6. After the support block 16 moves down and drives the first bending block 22 to bend the second steel strip 4, the first bending block 22 will move outward under the action of the first V-groove 27. The support block 16 continues to slide down and will drive the second bending block 30 to move into the stamping area 6 through the second linkage structure, thereby bending the first steel strip 3 again. The second bending block 30 is provided with a second notch 31 on one side of the support block 16. The second notch 31 can prevent the first bending block 22 from hitting the support block 16 and getting stuck. It should be noted that the support block 16 passes through the fixing plate 29 and forms an up-and-down sliding connection with the fixing plate 29. The fixing plate 29 is provided with a second slide rail 32 for the second bending block 30 to slide.

[0052] Specifically, the second linkage structure includes a second extension plate 33 disposed on the side of the support block 16 away from the stamping area 6, and a second U-shaped frame 34 symmetrically disposed on the second extension plate 33. The second U-shaped frame 34 includes second side rods 341 symmetrically disposed on both sides of the second extension plate 33 and a second connecting rod 342 connecting the two second side rods 341. The second bending block 30 is provided with a second sliding area 35 for the second side rods 341 to slide up and down, and a second V-shaped groove for the second connecting rod 342 to slide. 42. The second side rod 341 passes through the fixed plate 29 and forms a sliding connection with the fixed plate 29. The top of the second V-groove 42 is provided with an extension groove 36 for the second connecting rod 342 to slide up and down. When the support block 16 moves down and drives the first bending block 22 to move and bend, the second connecting rod 342 will slide in the extension groove 36 for one stroke. When the first bending block 22 retracts after bending, the second connecting rod 342 enters the second V-groove 42, thereby driving the second bending block 30 to move towards the stamping area 6 to bend.

[0053] Specifically, a third hydraulic cylinder 37 is provided on one side of the back of the substrate 44. An ejection support is fixed to the output end of the third hydraulic cylinder 37. The ejection support includes a top plate 38. A slide rail 45 is provided on the substrate 44 for the top plate 38 to slide. The top plate 38 has a U-shaped vertical cross-section, and the top plate 38 and the inner wall of the slide rail 45 form a first feed inlet 7. A pressure plate 39 is provided above the top plate 38. When the first bending blocks 22 on both sides bend the second steel strip 4, the third hydraulic cylinder 37 drives the top plate 38 to move towards the stamping area 6, causing the pressure plate 39 to be positioned at the first... Above the second steel strip 4, when the first bending block 22 moves to bend, there is a supporting force above to ensure smooth bending. The two sides of the top plate 38 will press against the U-shaped buckle, so that the second bending block 30 moves inward to bend the first steel strip 3, providing a supporting force. The third hydraulic cylinder 37 is fixed to the back of the base plate 44 through the plate part 41 and is located above the first steel strip 3, without interfering with the conveying of the first steel strip 3. The long plate 8 is provided with a limiting long plate 43, and the limiting long plate 43 has a steel strip opening for the first steel strip 3 to pass through, so that the steel strip enters the first feed port 7 more stably.

[0054] A specific application example of this embodiment is as follows:

[0055] When this device is in use, the first steel is conveyed to the stamping area 6 through the guide roller 9 and the first feed port 7, and then the second steel is conveyed to the stamping area 6 through the guide roller 9 and the second feed port 12 until one end abuts against the limiting plate 21. At this time, the second steel strip 4 in the stamping area 6 is stacked on top of the first steel strip 3.

[0056] The second hydraulic cylinder 15 is activated, which drives the support block 16 to move upward to the position where it contacts the bottom end of the first steel strip 3. Then the first hydraulic cylinder 13 is activated, which drives the stamping plate 14 downward and causes the support block 16 to enter the stamping chamber 17, thereby bending the first steel strip 3 and the second steel strip 4. At the same time, the stamping rod 19 enters the groove 18 to stamp the first steel strip 3 to form a recess 46.

[0057] The third hydraulic cylinder 37 is activated, which drives the top plate 38 to move into the stamping area 6 and positions the pressure plate 39 above the second steel strip 4. Then, the second hydraulic cylinder 15 drives the support block 16 to move down. The downward movement of the support block 16 will drive the first U-shaped frame 24 to move down through the first extension plate 25. The downward movement of the first U-shaped frame 24 will drive the first side plate to move in the first sliding area 26. At the same time, the first connecting rod 242 slides in the first V-shaped groove 27, thereby driving the first bending block 22 to slide along the first slide rail 23 and bend the second steel strip 4 inward again, thus forming a C-shaped buckle 1 covering the first steel strip 3.

[0058] When the first connecting rod 242 slides along the first V-groove 27, the second connecting rod 342 will slide downward in the extension groove 36 of the second bending block 30 without causing the second bending block 30 to slide. When the support block 16 continues to move downward and causes the first bending block 22 to slide outward, the second connecting rod 342 enters the second V-groove 42 and slides, thereby causing the second bending block 30 to move towards the stamping area 6, realizing the re-bending of the bending point of the first steel strip 3 to form a U-shaped hoop 201. When the second bending block 30 slides and bends, the first bending block 22 slides outward without interfering with the second bending block 30.

[0059] After the above process is completed, the packaging buckle is formed by stamping and bending. Then, the first steel strip 3 is cut by hydraulic shear 10. The third hydraulic cylinder 37 can then drive the push plate to move towards the stamping area 6 to push out the packaging buckle. After that, the first steel strip 3 and the second steel strip 4 are fed again to complete a cycle of packaging buckle manufacturing.

[0060] Step 4: Using a bending mechanism, bend the overlapping area of ​​the first steel strip 3 and the second steel strip 4 again at the bending point in Step 3, so that the bending point of the second steel strip 4 is tightened around the bottom of the first steel strip 3 to form a C-shaped buckle 1, and the bending point of the first steel strip 3 is tightened around the bottom of the C-shaped buckle 1.
