Description

Technical Field

[0001] This application relates to the field of riveting equipment technology, and more specifically, to an in-mold sheet feeding, positioning, and riveting structure. Background Technology

[0002] In-mold sheet feeding, positioning, and riveting structures are automated equipment components that integrate sheet material feeding, precise positioning, and riveting processing functions. They are primarily used in industries such as hardware, electronics, and automotive parts for riveting processing of strip-shaped and sheet-like metal or non-metal materials, such as forming riveting holes in metal sheets and riveting sheet parts to a substrate. In modern manufacturing, with increasing product precision requirements (e.g., the riveting error of some electronic components needs to be controlled within 0.1mm) and expanding production scale (daily output often reaches thousands or even tens of thousands of pieces), the traditional decentralized "feeding-positioning-riveting" operation mode is no longer sufficient. Enterprises urgently need a structure that can complete multiple processes collaboratively within a single piece of equipment, achieving continuous operation from sheet material feeding to processing completion. This reduces transfer time between processes, minimizes errors caused by manual intervention, and ultimately ensures product processing accuracy and production efficiency.

[0003] The in-mold sheet feeding, positioning, and riveting structure is a core equipment component developed based on this need. Traditional sheet riveting technology mostly adopts the mode of "manual feeding + single mechanism positioning + step-by-step riveting", which has many significant drawbacks in practical applications: First, feeding and positioning rely on manual operation. Operators need to place the sheet one by one into the riveting station and manually calibrate the position. This is not only time-consuming, but also easily affected by the experience and fatigue of the personnel, resulting in large sheet positioning errors. At the same time, the riveting process lacks an effective buffer and coordination mechanism. The action of the punch press and the positioning mechanism is not connected. After a single riveting is completed, the machine needs to be stopped and the part removed before the next round of operation can be carried out, which makes it impossible to form continuous production.

[0004] Therefore, this application proposes an in-mold sheet feeding, positioning, and riveting structure to solve the aforementioned problems. Utility Model Content

[0005] To address the aforementioned issues, this application provides an in-mold sheet feeding, positioning, and riveting structure.

[0006] The technical solution for the in-mold sheet feeding, positioning, and riveting structure provided in this application is as follows:

[0007] It includes a base 1, a punch press 2 fixedly mounted on the top of the base 1, and a guide seat 3 fixedly mounted on the top of the punch press 2. The feature is that it also includes a riveting mechanism.

[0008] The riveting mechanism includes part 4, first cylinder 5, and second cylinder 6. Part 4 is inserted into the top of guide seat 3, and the bottom of part 4 extends to one end of the bottom of guide seat 3. First cylinder 5 is fixedly installed on the outer wall of one end of punch press 2, and second cylinder 6 is fixedly installed on the outer wall of the end of punch press 2 away from first cylinder 5. First cylinder 5 and second cylinder 6 are parallel.

[0009] Furthermore, the riveting mechanism also includes a pushing part 7, a positioning part 8, and a movable block 9. The output end of the first cylinder 5 extends to one end of the inner wall of the punch press 2. The output end of the first cylinder 5 is fixedly connected to the pushing part 7. The positioning part 8 is fixedly installed on the top of the inner wall of the guide seat 3. The movable block 9 is inserted and fitted at the bottom of the positioning part 8.

[0010] Through the above technical solution, the output end of the first cylinder 5 is fixedly connected to the pushing part 7, so that the cylinder driving force can be directly transmitted to the pushing part 7, driving the pushing part 7 to achieve linear movement; the positioning part 8 is fixed on the top of the inner wall of the guide seat 3, which can provide a precise installation positioning reference for the movable block 9. The insertion and cooperation between the movable block 9 and the positioning part 8 not only ensures the guidance of the movable block 9 when it moves, but also allows the movable block 9 to move stably under the constraint of the positioning part 8, providing a guarantee for the position adjustment in the subsequent riveting operation.

[0011] Furthermore, a rivet post 10 is embedded in one end of the outer wall of the positioning part 8, and a strip-shaped product material 11 is provided at the top of the punch press 2 near the rivet post 10. One end of the strip-shaped product material 11 is in contact with the rivet post 10, and the other end of the strip-shaped product material 11 away from the rivet post 10 is in contact with the output end of the second cylinder 6.

[0012] Through the above technical solution, the riveting column 10 is embedded in the positioning part 8. With the help of the precise positioning part 8, the riveting column 10 is ensured to be in the preset riveting working position, providing a stable point of action for the riveting processing of the strip product material 11. The two ends of the strip product material 11 are in contact with the riveting column 10 and the output end of the second cylinder 6, respectively. The second cylinder 6 can apply a thrust to the strip product material 11 through the output end, which, together with the riveting column 10, achieves clamping and positioning of the strip product material 11, preventing displacement during the riveting process and ensuring processing accuracy.

[0013] Furthermore, parallel first springs 12 are respectively embedded at both ends of the inner wall of the guide seat 3 near the bottom.

[0014] Through the above technical solution, the first spring 12 is embedded in parallel at both ends of the bottom inner wall of the guide seat 3, which can provide elastic support or buffering inside the guide seat 3. When the relevant components move in the guide seat 3 and come into contact with the first spring 12, the first spring 12 can absorb the impact force of the movement, reduce the rigid collision between the components, and at the same time assist the components to reset, ensuring the smoothness of the structural movement and the service life of the components.

[0015] Furthermore, a second spring 13 is fixedly installed on the top of the inner wall of the guide seat 3, and the bottom of the second spring 13 is in contact with one end of the inner wall of the positioning part 8.

[0016] Through the above technical solution, the second spring 13 is installed between the top of the guide seat 3 and the positioning part 8, which can apply elastic pressure to the positioning part 8, so that the positioning part 8 always maintains a stable installation state, avoids the position of the positioning part 8 from shifting due to vibration and other factors, and thus ensures the accurate positioning of components such as the rivet column 10 that rely on the positioning part 8 for positioning. At the same time, when the positioning part 8 is subjected to external force, the second spring 13 can play a buffering role to protect the positioning part 8 from damage.

[0017] Furthermore, a riveting product 14 is placed on one end of the inner wall of the punch press 2, and the riveting product 14 is located directly below the movable block 9.

[0018] By using the above technical solution, the riveting product 14 is placed on the inner wall of the punch press 2 and directly below the movable block 9, so that the movable block 9 can accurately act on the riveting product 14 when it moves, ensuring that the riveting operation can be accurately applied to the preset position of the riveting product 14, avoiding the riveting product 14 from being unqualified due to positional deviation, and ensuring the processing quality of the riveting product 14.

[0019] Furthermore, the part 7 is pushed away from the outer wall of the first cylinder 5 and comes into contact with the end of the movable block 9.

[0020] Through the above technical solution, the part 7 is pushed into contact with the movable block 9, so that the first cylinder 5 can transmit the driving force to the movable block 9 by pushing the part 7, thereby driving the movable block 9 to perform corresponding actions and adjusting the position of the movable block 9. This allows the movable block 9 to accurately act on the riveting product 14 below to complete the riveting operation. This contact and cooperation relationship is the key to realizing power transmission and ensuring the accuracy of the movable block 9's actions.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] (1) Through automated collaborative design, the second cylinder can automatically push the strip product material to complete the feeding. The first cylinder drives the push parts to drive the movable block to realize the connection between positioning and riveting action. The fixed cooperation between the punch and the guide seat ensures that the riveting action is executed continuously. The whole process does not require machine stoppage intervention, forming a closed loop process from sheet material feeding to finished product output.

[0023] (2) This device eliminates the need for manual intervention through the automated collaboration of multiple components: the second cylinder can quickly push the sheet into place, and the precise cooperation between the positioning parts and the moving block achieves automatic positioning. The first cylinder drives the pushing parts to quickly complete the riveting action of the moving block, and the entire operation process forms an automated linkage. Furthermore, batch standardized operations can be achieved through parameter preset, without the need for manual adjustment, which greatly improves the overall production efficiency and helps enterprises respond quickly to order demands.

[0032] Example:

[0033] The following is in conjunction with the appendix Figure 1 -4 provides further detailed description of this application.

[0034] This application discloses an in-mold sheet feeding, positioning, and riveting structure, including a base, a punch press, a guide seat, and a riveting mechanism. The punch press is fixedly installed on the top of the base, the guide seat is fixedly installed on the top of the punch press, and the riveting mechanism is integrated into the overall structure. Each core component is fixedly connected to ensure stable assembly and guarantee the structural stability of the overall operation.

[0035] See Figures 1 to 4 The riveting mechanism includes a component, a first cylinder, a second cylinder, a pushing component, a positioning component, a movable block, and a riveting column. The component is inserted into the top of the guide seat, and its bottom extends to the bottom of the guide seat, thus providing auxiliary positioning and limiting for the internal components of the guide seat. The first cylinder and the second cylinder are respectively fixedly installed on the outer walls of both ends of the punch press, and the two are arranged in parallel to provide a stable and consistent driving force for subsequent actions. The output end of the first cylinder extends to the inner wall of the punch press, and its end is fixedly connected to the pushing component, which can achieve linear movement with the extension and retraction of the output end of the first cylinder. The positioning component is fixed to the top of the inner wall of the guide seat, and the movable block and the bottom of the positioning component are engaged by a plug-in fit. The method ensures the guidance and stability of the moving block during movement; the rivet pin is embedded in one end of the outer wall of the positioning part, and the position of the top of the punch press near the rivet pin is used to place the strip product material. One end of the strip product material contacts the rivet pin, and the other end contacts the output end of the second cylinder, forming a bidirectional constraint positioning; the position of the inner wall of the punch press directly below the moving block is used to place the riveted product, ensuring that the riveting action is accurately applied to the product; in addition, parallel first springs are embedded at both ends of the inner wall of the guide seat near the bottom, and a second spring is fixedly installed at the top of the inner wall of the guide seat. The bottom of the second spring contacts one end of the inner wall of the positioning part, and the elasticity of the spring realizes the buffering and component reset functions.

[0036] The following is a detailed description of each component of this application:

[0037] Base: As the basic supporting component of the entire structure, the base provides a stable mounting platform for the punch press through a robust structural design, preventing the overall position from shifting due to vibration during operation and ensuring the accuracy of subsequent riveting operations.

[0038] Punch press: As the core power actuator, it provides the necessary stamping power for riveting. Through the coordinated operation with the guide seat and riveting mechanism, it accurately transmits the power to the riveting position to complete the riveting process of the product.

[0039] Guide seat: plays a key guiding and positioning role, providing a precise installation benchmark for parts and positioning parts in the riveting mechanism, ensuring that each part moves within the preset trajectory, and avoiding the impact of part offset on machining accuracy.

[0040] The first cylinder: through the extension and retraction of the output end, it drives the part to move, transmits the driving force to the movable block, provides the power source for the movement of the movable block, and then controls the movable block to achieve position adjustment related to riveting.

[0041] The second cylinder applies thrust to the strip-shaped product material through contact with its output end. This, combined with the riveting column, forms a two-way constraint on the strip-shaped product material, preventing displacement of the material during the riveting process and ensuring positioning accuracy.

[0042] Pushing component: As an intermediate component for power transmission, it smoothly transmits the driving force of the first cylinder to the moving block, ensuring lossless power transmission and enabling the moving block to accurately respond to the action command of the first cylinder.

[0043] Positioning components: These provide a fixed installation and positioning reference for the movable block and the riveting column. Through their fixed position, they ensure that the movement trajectory of the movable block and the action position of the riveting column remain precisely aligned, making them one of the core components for ensuring riveting accuracy.

[0044] Movable block: Driven by the pushing parts, it moves along the insertion trajectory of the positioning parts and finally acts on the riveting product below, combining the stamping power of the punch press with the driving force of the cylinder to achieve precise riveting of the product.

[0045] Riveting pin: It is fixed to the positioning part by embedding. With the help of the precise positioning part, it becomes a stable point of action for riveting strip material, ensuring that the riveting action can be accurately applied to the preset position of the material.

[0046] First spring: Installed on the inner wall at the bottom of the guide seat, it absorbs the impact force generated when the moving block moves through its elastic extension and contraction characteristics, reduces rigid collisions between the moving block and other components, and assists the moving block to quickly reset after action, ensuring the smoothness of subsequent cycle operations.

[0047] The second spring is located between the top of the guide seat and the positioning part. It keeps the positioning part in a stable installation state through elastic pressure, preventing the positioning part from shifting due to vibration or external force. At the same time, it plays a buffering role when the positioning part is impacted, thus extending the service life of the component.

[0048] Strip-shaped product material placement area: Through cooperation with the riveting column and the output end of the second cylinder, a two-way positioning of the material is formed, ensuring that the material maintains a fixed posture during processing, providing a prerequisite for precise riveting.

[0049] Riveting product placement area: By being positioned directly below the movable block, the riveting action of the movable block can be accurately applied to the product's processing location, avoiding product defects caused by positional deviation.

[0050] The implementation principle of the in-mold sheet feeding, positioning, and riveting structure in this application embodiment is as follows: During riveting, the strip-shaped product material is first placed at a preset position on the top of the punch press, with one end in contact with the riveting column and the other end in contact with the output end of the second cylinder. The output end of the second cylinder extends and applies a pushing force to the material, cooperating with the riveting column to complete the bidirectional constraint positioning of the strip-shaped product material. At the same time, the riveted product is placed directly below the movable block on the inner wall of the punch press, ensuring that the product to be processed is aligned with the movable block. Subsequently, the first cylinder is activated, its output end extends and drives the pushing part to move towards the movable block. After the pushing part contacts the movable block, it drives the movable block to move downward along the insertion trajectory of the positioning part until the movable block approaches the riveted product. At this time, the punch press is activated, providing punching power and driving the movable block to move further downward. Combined with the supporting effect of the riveting column, the riveting processing of the strip-shaped product material and the riveted product is completed. During the riveting process... The second spring inside the guide seat cushions the impact force between the movable block and the positioning part through elasticity, preventing rigid damage to the component. After riveting is completed, the first spring pushes the movable block upward with its elastic reset characteristic. At the same time, the output ends of the first and second cylinders retract, pushing the part back to its original position with the first cylinder. The movable block returns to its initial position under the synergistic action of the first spring and the pushing part, completing one riveting cycle. In addition, the overhead contact structure design (through the gap fit and motion trajectory planning of each component) allows air to circulate inside the structure. Especially during the gaps in the riveting cycle, air circulation can help remove the heat generated by the component operation and reduce the noise generated by friction between components. The material and structural design of each component are all based on the three core objectives of "precise positioning, stable power transmission, and buffer protection", ensuring that the overall structure maintains a high-efficiency and stable operating state during continuous riveting operations, improving processing quality and work efficiency.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
