Description

Technical Field

[0001] The present invention belongs to the technical field of stamping forming, and particularly relates to a stamping forming device for a seat belt retractor with a cooling mechanism. Background Art

[0002] The seat belt retractor is a key component in the vehicle seat belt system. Its main function is to wind up the slack part of the seat belt under normal circumstances and quickly lock in case of an emergency to limit the forward movement of the occupant, thereby reducing injuries.

[0003] The guide ring of the seat belt retractor is an important component in the seat belt system. Its main role is to guide the path of the seat belt, ensure smooth movement of the seat belt during winding and unwinding, and maintain appropriate tension.

[0004] In the existing stamping forming technology field, cooling means are often provided in stamping equipment to cool down the stamped products. However, as an independent part, the guide ring has structural design requirements to form four precise small holes on the upper side through the front stamping process, and a flanging structure needs to be formed on the lower side through the reverse stamping process. This requirement for double-sided stamping means that the material must undergo two independent stamping operations. However, this process is not without challenges: the heat generated during the stamping operation will cause the product temperature to rise. At the same time, the edges of the product often become sharp and rough after stamping, which not only increases the safety hazards during operation but also makes it difficult to quickly and accurately remove and flip the product. These factors jointly affect the flipping and adjustment process of the product after half stamping, thereby reducing the efficiency of the entire stamping process.

[0005] Based on this, the present invention designs a stamping forming device for a seat belt retractor with a cooling mechanism to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a stamping forming device for a seat belt retractor with a cooling mechanism to solve the problems of low processing efficiency and potential safety hazards during the stamping processing of products.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0012] The movable blocking mechanism includes a sliding frame fixedly connected to the backing plate. A sliding block is slidably connected in the sliding frame. A moving frame is fixedly connected to the sliding block, and two extending parts are arranged at the position close to the top inside the moving frame.

[0013] As a further description of the above technical solution:

[0014] A contact block is arranged on the inner wall of the moving frame. The contact block is triangular, and the inner walls of the sliding block and the sliding frame are both T-shaped.

[0015] As a further description of the above technical solution:

[0016] The flipping support mechanism includes a movable rotating component arranged through the front of the sliding seat. An extrusion frame is arranged on the side of the movable rotating component away from the lower die. A first fixing rod is fixedly connected to the outside of the extrusion frame, and the first fixing rod is fixedly connected to the outside of the lower die base.

[0017] As a further description of the above technical solution:

[0018] One side of the extrusion frame close to the lower mold is composed of an inclined section and a vertical section. The movable rotating assembly includes two limit posts and a bearing penetrating through the front surface of the sliding seat. A rotating shaft is rotatably connected inside the bearing. The front surface of the rotating shaft is connected with a sliding sleeve in a penetrating manner. A sliding rod in the shape of a rectangle is slidably connected inside the sliding sleeve. The sliding rod is fixedly connected with a movable clamping plate. One end of the sliding rod close to the extrusion frame is fixedly connected with a circular block.

[0019] As a further description of the above technical solution:

[0020] The position of the circular block corresponds to the position of the extrusion frame. The limit posts are fixedly connected outside the sliding seat.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, when the electric slider drives the sliding seat to slide upward along the electric slide rail, the upward movement of the sliding seat will synchronously drive the upward movement of the sliding rod and the circular block. During this process, the circular block is affected by the inclined surface of the extrusion frame, and then pushes the circular block, the sliding rod, and the moving clamping plate towards the product, thereby achieving precise clamping of the product. As the sliding seat continues to rise, the extension column contacts the extension part, triggering the extrusion of the extension part on the extension column, the rotating shaft, the moving clamping plate, and the magnetic baffle, prompting this combination to rotate. During the rotation process, the magnetic baffle contacts the limiting column on the opposite side, and using the magnetic force between the limiting column and the magnetic baffle, the stability of the rotating shaft is ensured, thus successfully completing the flipping of the product, realizing the automatic clamping and flipping of the product after semi-stamping, effectively avoiding the risk of scratches caused by the sharp edges of the product during the operation process, and at the same time, there is no need to worry about the scalding problem that may be caused by the high temperature of the product; this device not only significantly improves the operation efficiency and safety, but also ensures the continuity and stability of the production process.

[0029] 2. In the present invention, while the sliding seat slides vertically, the upward movement of the support sleeve is precisely controlled. The support sleeve drives the moving rod to move upward through the support rod. Thanks to the precise guidance of the guiding hole, the moving rod can achieve reciprocating sliding in the horizontal direction during the upward movement. This mechanism ensures the smooth horizontal movement of the support rod inside the support sleeve. When the connecting seat and the nozzle move along with it, the lubricating oil can be effectively sprayed evenly on the surfaces of the product and the lower mold, thereby realizing the comprehensive and efficient lubrication treatment of the mold and the surface of the semi-stamped product. This spraying method not only ensures the uniform distribution of the lubricating oil on the contact surface between the product and the mold, but also greatly improves the lubrication efficiency, reduces friction and wear, improves the forming quality of the product and the service life of the mold. This device not only improves the stamping processing efficiency, but also significantly enhances the operation safety and the reliability of the product. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0042] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0043] Please refer to the attached Figure 1 - attached Figure 10 , the present invention provides a technical solution: a stamping and forming device for a seat belt retractor with a cooling mechanism, including a control cabinet 1, an upper die holder 6 and a lower die holder 5. A support seat 4 is fixedly connected to the control cabinet 1 and is arranged below the lower die holder 5. A lower die 8 is arranged inside the lower die holder 5, and an upper die 7 is arranged inside the upper die holder 6. A guide post 9 is arranged between the upper die holder 6 and the lower die holder 5. A driving mechanism 10 connected to the control cabinet 1 is arranged on the upper die holder 6 of the guide post 9. Two backing plates 11 are fixedly connected to the lower die holder 5, and a movable blocking mechanism 12 is fixedly connected to the backing plates 11. An electric slide rail 13 is fixedly connected to the backing plates 11, and an electric slider 14 is arranged inside the electric slide rail 13. A sliding seat 15 is fixedly connected to the side of the electric slider 14. A flipping support mechanism 16 is connected through the front of the sliding seat 15. One end of the flipping support mechanism 16 close to the lower die 8 is fixedly connected to a movable clamping plate 17. The flipping support mechanism 16 is fixedly connected outside the lower die holder 5. A sliding spraying mechanism 22 arranged on the lower die holder 5 is fixedly connected to the sliding seat 15. Four second fixing rods 18 are fixedly connected to the lower die holder 5, and a side plate 19 is fixedly connected to the top of the second fixing rods 18. A guide hole 20 is opened on the side of the side plate 19, and the sliding spraying mechanism 22 is slidably arranged inside the guide hole 20.

[0044] The driving mechanism 10 is used to control the downward movement of the upper die 7 and the upper die holder 6. The cooperation between the upper die 7 and the lower die 8 is used for stamping and forming the material. The electric slide rail 13 and the electric slider 14 adopted can control the vertical movement of the sliding seat 15 and the movable clamping plate 17;

[0045] Specifically, as Figure 1 and Figure 9 shown, a storage frame 3 is connected to the control cabinet 1. A guide groove 21 is opened below the side plate 19, and the sliding spraying mechanism 22 is slidably arranged inside the guide groove 21. The guide groove 21 is set as a T shape, and a moving wheel 2 is fixedly connected to the lower part of the control cabinet 1.

[0046] The guide groove 21 is used to guide the horizontal movement of the sliding spraying mechanism 22 to prevent the sliding spraying mechanism 22 from rotating and shaking;

[0047] Specifically, as Figures 3 - 5As shown, the movable blocking mechanism 12 includes a sliding frame 121 fixedly connected to the backing plate 11. A sliding block 122 is slidably connected within the sliding frame 121. A movable frame 123 is fixedly connected to the sliding block 122. Two extension parts 125 are provided at a position near the top inside the movable frame 123.

[0048] A contact block 124 is provided on the inner wall of the movable frame 123. The contact block 124 is triangular in shape. The inner walls of both the sliding block 122 and the sliding frame 121 are T-shaped.

[0049] The contact block 124 cooperates with the extension post 1619. When the extension post 1619 moves, it presses against the inclined surface of the contact block 124, enabling the adjustment of the position of the movable frame 123, achieving the correspondence between different extension parts 125 and the extension post 1619. By using the sliding block 122 and the sliding frame 121, the movement of the movable frame 123 and the extension parts 125 is guided to ensure the stable movement of the movable frame 123. The extension parts 125 block the movement process of the extension post 1619, achieving the control of the rotation of the extension post 1619 and the rotating shaft 1612;

[0050] Specifically, as Figures 5 - 8 shown, the flipping support mechanism 16 includes a movable rotating assembly 161 penetrating through the front surface of the sliding seat 15. On the side of the movable rotating assembly 161 away from the lower mold 8, there is an extrusion frame 162. A first fixed rod 163 is fixedly connected to the outside of the extrusion frame 162, and the first fixed rod 163 is fixedly connected to the outside of the lower die base 5.

[0051] The side of the extrusion frame 162 close to the lower mold 8 consists of an inclined section and a vertical section. The movable rotating assembly 161 includes two limit posts 1618 and a bearing 1611 penetrating through the front surface of the sliding seat 15. A rotating shaft 1612 is rotatably connected within the bearing 1611. A sliding sleeve 1613 is connected through the front surface of the rotating shaft 1612. A sliding rod 1614 in the shape of a rectangle is slidably connected within the sliding sleeve 1613. The sliding rod 1614 is fixedly connected to the movable clamping plate 17. A circular block 1615 is fixedly connected to one end of the sliding rod 1614 close to the extrusion frame 162.

[0052] The position of the circular block 1615 corresponds to the position of the extrusion frame 162. The limit posts 1618 are fixedly connected to the outside of the sliding seat 15. A magnetic baffle 1617 is provided on the side surface of the rotating shaft 1612 corresponding to the position of the limit posts 1618. When the magnetic baffle 1617 rotates to contact the limit posts 1618, the sides close to each other have opposite magnetic properties.

[0053] Two extension posts 1619 are provided on the side surface of the rotating shaft 1612 close to the movable clamping plate 17. The positions of the extension posts 1619 correspond to the positions of the extension parts 125, and the positions of the extension posts 1619 correspond to the positions of the triangular contact blocks 124.

[0054] The cooperation between the magnetic baffle 1617 and the limit post 1618 defines the rotational limit positions on both sides of the rotating shaft 1612. Moreover, the magnetic force between them makes the rotation process of the rotating shaft 1612 smoother. The bearing 1611 limits the rotation of the rotating shaft 1612, the sliding rod 1614, and the moving clamping plate 17, facilitating the flipping action of the moving clamping plate 17 after clamping the product. When the circular block 1615 is squeezed by the inclined surface of the extrusion frame 162, the sliding rod 1614 and the moving clamping plate 17 can be controlled to clamp the product. The elastic component 1616 applies an elastic force to the sliding rod 1614 to prevent the sliding rod 1614 from shaking randomly. The sliding sleeve 1613 guides the rectangular sliding rod 1614, ensuring that the sliding rod 1614 slides stably within the rotating shaft 1612. When the extension post 1619 is blocked by the extension portion 125 as the sliding seat 15 moves, the rotation of the rotating shaft 1612 can be controlled.

[0055] Specifically, as Figure 3 and Figures 9 - 10 shown, the sliding spraying mechanism 22 includes two moving rods 221 slidably arranged in the guiding holes 20. The moving rods 221 are cylindrical. A connecting sleeve 222 is slidably connected to the outside of the moving rods 221. A guiding block 223 is fixedly connected to the outside of the connecting sleeve 222. The guiding block 223 is slidably connected in the guiding groove 21. One end of the moving rod 221 close to the sliding seat 15 is fixedly connected with a communicating seat 224. A spray head 225 is communicated with one side of the communicating seat 224 close to the sliding seat 15.

[0056] The guiding holes 20 are composed of a continuous inclined section hole structure. A support rod 226 is fixedly connected to the moving rod 221. A support sleeve 227 is slidably connected to the outside of the two support rods 226. The support sleeve 227 is fixedly connected to the sliding seat 15.

[0057] The guiding groove 21 guides the movement of the guiding block 223 and the connecting sleeve 222, ensuring that the moving rod 221 and the communicating seat 224 do not rotate during movement. The support sleeve 227 is used to control the up and down movement of the support rod 226 and the moving rod 221 through the movement of the sliding seat 15. Moreover, the support rod 226 can slide horizontally within a certain range in the support sleeve 227. The moving rod 221 cooperates with the guiding hole 20. The upward moving rod 221 is guided by the guiding hole 20 to control the reciprocating movement of the moving rod 221 in the horizontal direction. The communicating seat 224 sprays lubricating oil on the lower die 8 and the product surface through the spray head 225.

[0058] Working principle, when in use: After stamping one side of the product, when it is necessary to perform stamping forming on the other side, the ejecting mechanism in the lower die 8 ejects the product upward. After the product is separated from the lower die 8, the electric slider 14 is controlled to slide upward in the electric slide rail 13. While the sliding seat 15 moves upward, it will control the sliding rod 1614 and the circular block 1615 to move upward. When the moving clamping plate 17 moves upward to the position corresponding to the product, the circular block 1615 is squeezed by the inclined surface of the squeezing frame 162, and the circular block 1615, the sliding rod 1614 and the moving clamping plate 17 move closer to the product;

[0059] The moving clamping plate 17 realizes the clamping of the product. Subsequently, the sliding seat 15 continues to move upward. When the extension column 1619 contacts the extension part 125, the extension part 125 is controlled to squeeze the extension column 1619, the rotating shaft 1612, the moving clamping plate 17 and the magnetic baffle 1617 to rotate. The magnetic baffle 1617 rotates until it contacts the limiting column 1618 on the other side. The magnetic force between the limiting column 1618 and the magnetic baffle 1617 keeps the rotating shaft 1612 stable, and at the same time, the product is flipped. While the sliding seat 15 moves upward, it controls the support sleeve 227 to move upward. The support sleeve 227 controls the moving rod 221 to move upward through the support rod 226. Due to being guided by the guiding hole 20, the moving rod 221 controls the support rod 226 to slide horizontally in the support sleeve 227, realizing the horizontal reciprocating sliding of the moving rod 221 during the process of moving upward;

[0060] When the connecting seat 224 and the nozzle 225 move, lubricating oil is sprayed on the product and inside the lower die 8. The electric slider 14 slides downward in the electric slide rail 13 until the extension column 1619 contacts the contact block 124. The contact block 124 and the moving frame 123 are controlled to move along the sliding frame 121, so that the corresponding extension part 125 slides to the position corresponding to the extension column 1619. When the circular block 1615 moves downward to be separated from the inclined part of the squeezing frame 162, the elastic component 1616 controls the sliding rod 1614 and the moving clamping plate 17 to be separated from the product. After the product is flipped, it falls on the ejecting mechanism, and then the upper die 7 is controlled to move by the driving mechanism 10 to perform stamping forming on the product again.

[0061] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
