[0036] This application discloses a bending mechanism for processing products, including a product body and pins connected to the product body, suitable for bending the product pins. This bending mechanism is also applicable to other products requiring bending. This embodiment uses pin bending as an example, where the product includes a product body and product pins; the product in this embodiment has two pins. Figure 1 This is a schematic diagram showing the original state of the product pins. Figure 2 This is a schematic diagram of the product pins after bending. The product pins are bent using a bending mechanism to improve pin installation accuracy and meet diverse layout requirements.

[0037] Please see Figure 3 This is one embodiment of the bending mechanism in this application. The bending mechanism includes a base plate 1, a fixed seat 2, and a bending component 3. The fixed seat 2 is fixedly disposed on the base plate 1 and is used to support and fix the product body. The bending component 3 is disposed on one side of the fixed seat 2 and is used to bend the product pins fixed to the fixed seat 2.

[0038] Please see Figure 3 and Figure 4The mounting base 2 is provided with a positioning groove 21 and a mounting groove 22, both open at one end. The positioning groove 21 is used to position the product body to reduce product body shaking. The mounting groove 22 is connected to the positioning groove 21, and the center line of the mounting groove 22 is perpendicular to the center line of the positioning groove 21 for easy product placement and removal. The length direction of the positioning groove 21 is consistent with the length direction of the product, and the product body is located inside the positioning groove 21. The product pins extend along the opening of the positioning groove 21, and the mounting groove 22 facilitates the gripping of the product located inside the positioning groove 21. Specifically, a first baffle 23 extends from the inner wall of the opening of the positioning groove 21 toward the opening of the positioning groove 21. The first baffle 23 is fixedly connected to the mounting base 2. The product pins are attached to the first baffle 23 and extend along the direction of the first baffle 23. The length of the product pins is greater than the length of the first baffle 23, that is, the end of the product pins protrudes from the end of the first baffle 23. The first baffle 23 provides force to part of the product pins.

[0039] Please see Figure 4 and Figure 5 The bending assembly 3 includes a first bending member 31 and a driving member 32. The first bending member 31 is located at the opening end of the positioning groove 21. The first bending member 31 is slidably disposed on the base plate 1 in a direction perpendicular to the opening of the positioning groove 21. The first bending member 31 is provided with a first bending portion. The driving member 32 is used to drive the first bending member 31 to move so that the first bending portion pushes against the product pin and bends the product pin once. Furthermore, the first bending portion and the first baffle 23 are spaced apart along the movement direction of the first bending member 31. The product pin is placed between the first baffle 23 and the first bending portion. It can be understood that the product pin extends through the opening of the positioning groove and is placed between the first baffle 23 and the first bending portion. When it is necessary to bend the product pin, the driving member is activated to drive the first bending member 31 to slide in a direction perpendicular to the opening of the positioning groove. The first bending member 31 drives the first bending portion to move synchronously to approach and push the product pin, so that the product pin is subjected to the shearing force generated by the relative movement of the first baffle 23 and the first bending portion and thus undergoes plastic deformation, so as to achieve bending of the product pin in one operation and realize the automated bending operation of the product pin.

[0040] In order to achieve the first bending part pushing against the product pin and bending the product pin in one step, in this embodiment, a second baffle 33 is provided at the end of the first bending part 31 facing the fixing seat 2. The second baffle 33 is parallel to the first baffle 23 and located on one side of the first baffle 23. There is a gap between the end of the second baffle 33 and the first baffle 23, which is greater than or equal to the thickness of the product pin, for the product pin to be inserted. That is, the first bending part is configured as the second baffle 33. The product pin bending process is as follows: The product is placed on the fixed base 2, and the product body is positioned by the positioning groove 21. The product pin extends out through the opening of the positioning groove 21. The first baffle 23 is fixed, and the first bending component 31 drives the second baffle 33 to move in a direction perpendicular to the first baffle 23 under the drive of the driving component 32. The second baffle 33 reciprocates relative to the first baffle 23. As the second baffle 33 moves towards the first baffle 23 during the movement, it contacts the product pin. The product pin is subjected to shear force formed by the opposing forces of the first baffle 23 and the second baffle 33 during their relative movement, and thus undergoes plastic deformation. The product pin is bent with the end of the first baffle 23 as the bending point to achieve the required bending angle. At this time, the product pin presents the shape of state one, such as... Figure 6 As shown.

[0041] This application employs a simple linear motion mechanism to complete complex three-dimensional shape transformation tasks, enabling automated bending operations of product pins. Since the position and speed of the second baffle 33 are precisely controlled by the external drive component 32, the product positioning accuracy is high, ensuring consistency in each processing step. Compared to traditional manual adjustments, it is more efficient and stable, reducing labor intensity and improving production efficiency. Simultaneously, it reduces the risk of errors caused by human factors, increasing product yield. It is suitable for the production needs of various materials and sizes; by reasonably adjusting the parameters, it can meet the application requirements in different scenarios. Compared to large and complex equipment, it occupies a much smaller area, allowing multiple such workstations to be easily deployed in limited workshops to collaboratively improve overall production capacity.

[0042] In other embodiments, the first bending portion can be configured as a groove, with the product pin extending along the direction of the first baffle 23 and the end of the product pin located in the groove. The drive member 32 drives the first bending member 31 to move so that the product pin is bent under the push of the inner wall of the groove.

[0043] To facilitate smooth and precise movement of the first bending member 31, the base plate 1 is provided with a guide rail 11, which extends in a direction perpendicular to the first baffle 23. The guide rail 11 guides the movement of the first bending member 31. A guide block 311 is provided on the end face of the first bending member 31 facing the base plate 1. The guide block 311 is slidably connected to the guide rail 11 to reduce friction between the first bending member 31 and the base plate 1. Furthermore, the bending mechanism also includes a mounting base 5, a mounting plate 6, and a guide rod 7. The mounting base 5 is located on the left side of the first bending member 31, the guide rod 7 is fixedly mounted on the mounting base 5, and the mounting plate 6 is slidably mounted on the mounting base 5 via the guide rod 7. The mounting plate 6 is fixedly mounted on the upper end face of the first bending member 31. In this embodiment, the guide rail 11 is located at the lower end of the first bending member 31, and the guide rod 7 is located at the upper end of the first bending member 31. The guide rail 11 and the guide rod 7 work together to guide the movement of the first bending member 31, so that the first bending member 31 moves along a predetermined trajectory to accurately bend the product pin.

[0044] Please see Figure 5 and Figure 6 Furthermore, in order to continue bending the product pins to meet the arrangement conditions, the bending assembly 3 also includes a second bending member 34 disposed on one side of the first bending member 31. The second bending member 34 is movably disposed on the base plate 1 along a direction perpendicular to the first bending member 31. The driving member 32 is connected to the second bending member 34 and is used to drive the second bending member 34 to move closer to the fixed seat 2 along a direction perpendicular to the first bending member 31 to bend the product pins a second time. In this embodiment, the second bending member 34 moves along a direction perpendicular to the first bending member 31, that is, the second bending member 34 moves toward or away from the first baffle 23. The second bending member 34 is disposed at the output end of the driving member 32. When the second bending member 34 moves toward the first baffle 23, it simultaneously drives the first bending member 31 to move gradually away from the first baffle 23. Similarly, when the second bending member 34 moves away from the first baffle 23, it simultaneously drives the first bending member 31 to move gradually closer to the first baffle 23.

[0045] Specifically, the first bending member 31 is provided with a first guide slope 312, and the second bending member 34 is provided with a second guide slope 341. The first guide slope 312 abuts against the second guide slope 341, and the first guide slope 312 and the second guide slope 341 are parallel. The end of the first guide slope 312 near the fixed base 2 gradually converges towards the center line of the second bending member 34. It can be understood that the driving member 32 provides driving force to the second bending member 34, causing the second bending member 34 to move linearly towards the fixed base 2 along a predetermined trajectory. The second guide slope 341 is designed on the second bending member 34. During the movement of the second bending member 34, the second guide slope 341 will come into contact with the first guide slope 312 and generate an interaction force. According to the orthogonal decomposition law in physics, this force can be divided into two components: one perpendicular to the contact surface and one parallel to the contact surface. The parallel component causes the first bending member 31 to make a horizontal displacement. Based on the principle of geometric linkage and the force transmission mechanism, the two independent operations that originally needed to be controlled separately are integrated into a simple mechanical unit, reducing the need for additional power components and realizing the composite motion effect under the single action of the drive component 32. This achieves the purpose of the first bending component 31 and the second bending component 34 operating synchronously and bending the product pins step by step.

[0046] Please see Figure 6 and Figure 7 Furthermore, the end of the second bending member 34 facing the fixed base 2 is provided with a second bending portion 342, which is directly opposite the first baffle 23. The second bending portion 342 is provided with a first bending surface 3421 and a second bending surface 3422. When the driving member 32 drives the second bending member 34 to move towards the first baffle 23, the first baffle 23 and the product pin simultaneously extend into the second bending portion 342, and the product pin undergoes a secondary bending under the action of the first bending surface 3421 and the second bending surface 3422. In this embodiment, the first bending surface 3421 and the second bending surface 3422 are perpendicular to each other, the first bending surface 3421 is provided corresponding to the fixed base 2, and the second bending surface 3422 is provided corresponding to the first baffle 23.

[0047] Understandably, the driving component 32 drives the second bending component 34 to move towards the first baffle 23, while simultaneously causing the first bending component 31 to gradually move away from the first baffle 23. The first baffle 23 and the second baffle 33 cooperate to perform a preliminary bending process on the product pin portion along the horizontal direction. Under the driving force of the driving component 32, the second bending component 34 continues to move towards the first baffle 23. Therefore, the second bending portion 342 gradually moves closer to the first baffle 23. When the external force of the second bending portion 342 acts on the product pin, under the action of the first bending surface 3421 and the second bending surface 3422, the first baffle 23 and the product pin simultaneously extend into the second bending portion 342, and the product pin undergoes bending deformation. Since the first bending surface 3421 and the second bending surface 3422 are perpendicular to each other, the product pin is guided to complete a partial bend, bending from the shape of state one to the shape of state two. At this time, the product pin has two right-angle bending segments, and the first baffle 23 is located between the two right-angle bending segments. Figure 7 As shown.

[0048] Please see Figure 7 and Figure 8 Furthermore, the first bending member 31 has a clamping block 313 on its end face facing the fixed base 2. The clamping block 313 has a connecting part 3131 and an abutting part 3132. The connecting part 3131 is fixedly connected to the fixed base 2. The abutting part 3132 is located at the end of the connecting part 3131 near the fixed base 2 and is perpendicular to the connecting part 3131. The abutting part 3132 is located at the end of the connecting part 3131 facing the first baffle 23. The abutting part 3132 is used to press against the first baffle 23 to bend the product pin located between the abutting part 3132 and the first baffle 23. Understandably, after the second bending member 34 completes the secondary bending of the product pin, the driving member 32 drives the second bending member 34 to move away from the fixed base 2, so that the second bending part 342 disengages from the product pin; at the same time as the second bending member 34 moves away from the fixed base 2, the first bending member 31 gradually returns to its original position, and the first bending member 31 drives the clamping block 313 to move synchronously. At this time, the clamping block 313 gradually approaches the first baffle 23 so that the abutment part 3132 contacts the product pin and gradually presses against the product pin, so that the side of the product pin away from the abutment part 3132 presses against the first baffle 23, thereby realizing the third bending process of the product pin. At this time, the product pin presents the shape of state three, such as Figure 8 As shown, the product pins are processed from their original state to a finished product state after bending through three bending operations, thus meeting the requirements for diverse pin arrangement.

[0049] Please see Figure 3 and Figure 5In this embodiment, to accommodate the arrangement of the two product pins, two sets of first bending members 31 are provided, symmetrically arranged along the center line of the second bending member 34. The driving member 32 drives the second bending member 34 to move synchronously, causing the two sets of first bending members 31 to move synchronously. The initial bending process of the two product pins is completed synchronously through the arrangement of the two sets of first bending members 31. Correspondingly, two sets of second bending parts 342 are provided, each corresponding to one of the two sets of first baffles 23, and symmetrically arranged along the center line of the second bending member 34. After the initial bending process of the product pins, the second bending member 34 continues to move towards the first baffle 23 under the driving force of the driving member 32, and the secondary bending process of the two product pins is completed synchronously through the arrangement of the two sets of second bending parts 342. Correspondingly, since there are two sets of the first bending member 31, there are also two sets of clamping blocks 313. The two sets of clamping blocks 313 are symmetrically arranged along the center line of the second bending member 34. After the product pin is bent twice, the driving member 32 drives the second bending member 34 to move away from the fixed base 2. The second bending part 342 disengages from the product pin. At the same time, the two sets of first bending members 31 move towards each other to gradually return to their original positions. The first bending member 31 drives the clamping blocks 313 to move synchronously so that the abutting part 3132 contacts the product pin and gradually presses against the product pin, thus completing the three bending processes of the two product pins simultaneously.

[0050] To achieve synchronous movement of the two sets of first bending members 31, the bending assembly 3 also includes an elastic member 35. The two ends of the elastic member 35 are respectively connected to the two sets of first bending members 31. The elastic member 35 is used to drive the two sets of first bending members 31 to move towards each other to reset when the second bending member 34 moves away from the fixed seat 2. In this embodiment, the elastic member 35 is preferably a spring. To accommodate the arrangement of the two sets of first bending members 31, two sets of mounting seats 5, mounting plates 6, and guide rods 7 are each provided. The two sets of mounting seats 5 are located on both sides of the two sets of first bending members 31. The two ends of the elastic member 35 are respectively fixedly connected to the two sets of mounting plates 6. There is space between the elastic member 35 and the base plate 1 for the movement of the second bending member 34, allowing the second bending member 34 to move smoothly along a preset path. Understandably, the driving component 32 provides driving force to the second bending component 34, causing the second bending component 34 to move linearly toward the fixed seat 2 along a predetermined trajectory. Under the action of the first guide slope 312 and the second guide slope 341, the two first bending components 31 move in opposite directions along a direction perpendicular to the first baffle 23. At this time, the elastic component 35 is stretched. After the product pin completes the second bending, the driving component 32 drives the second bending component 34 to move away from the fixed seat 2. The two sets of first bending components 31 move toward each other under the rebound force of the elastic component 35 to return to their original positions.
