[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example 1 like Figure 1-18 As shown, a multifunctional continuous forming mold for a connecting plate of a car seat recliner comprises a floating upper seat 1 and a fixed lower seat 2. The floating upper seat 1 is plate-shaped and can be a pressing plate of a press. During operation, the press pushes the floating upper seat 1 to move downward, thereby driving the punch to work. The fixed lower seat 2 can be a workbench of a press. A support frame 4 is installed on the fixed lower seat 2, and a punching die is installed on the upper end of the support frame 4. An elastic reset structure 7 is installed between the floating upper seat 1 and the fixed lower seat 2. The elastic reset structure 7 comprises an upper connecting plate 34 that cooperates with the floating upper seat 1 and a lower connecting plate 35 that cooperates with the support frame 4. A downward guide shaft 36 is installed on the lower connecting plate 35, and a guide hole that cooperates with the guide shaft 36 is processed on the upper connecting plate 34. A reset spring 37 is installed between the upper connecting plate 34 and the lower connecting plate 35. There are multiple elastic reset structures 7, which are distributed on both sides of the continuous forming mold to reset the punch upward.

[0022] A feeding guide mechanism, a blanking positioning structure, and a continuous blanking structure are sequentially installed between the floating upper seat 1 and the fixed lower seat 2.

[0023] The feed guide structure includes guide rollers installed on both sides of the feed port, and guide blocks 11 are installed at the ends of the guide rollers to guide the raw material plate 32 so that the raw material plate 32 enters the continuous forming mold from the middle position. The blanking positioning structure includes a limiting column structure 8 installed between the floating upper seat 1 and the support frame 4. The limiting column can control the descending stroke of the floating upper seat 1. There are multiple groups of limiting column structures 8, which are distributed on the edge of the forming mold.

[0024] The raw material plate 32 enters the continuous punching structure after being guided by the guide roller. The continuous punching structure includes a punching structure, a forming structure, a selection processing structure and a cutting structure installed in sequence. In this embodiment, the continuous punching structure is installed between the integrally formed push plate 3 and the integrally formed die support plate 6. The elastic reset structure 7 and the limiting column structure 8 are both installed between the push plate 3 and the die support plate 6. To ensure structural strength, the push plate 3 and the die support plate 6 are both made of steel plates with a thickness of 15-20 mm.

[0025] The blanking structure is used to blank out the outer contour of the angle adjuster connecting plate on the raw material plate 32. The blanking structure includes a blanking punch fixing plate 12 connected to the push plate 3. The blanking punch mounting port is processed on the blanking punch fixing plate 12. The blanking punch is installed at the blanking punch mounting port. A blanking pressure plate 23 is also installed on the lower side of the blanking punch fixing plate 12. The blanking punch passes downward through the blanking pressure plate 23. The tolerance between the blanking punch and the blanking pressure plate 23 is matched, and then the blanking punch is guided by the blanking pressure plate 23. In this embodiment, the blanking pressure plate 23 is connected to a blanking clamping device, which includes a plurality of elastic buffers distributed between the push plate 3 and the blanking pressure plate 23. The elastic buffer is selected A gas spring 13 is used, and a positioning groove 22 that cooperates with the gas spring 13 is processed on the push plate 3. A threaded hole is processed at the bottom of the positioning groove 22, and then it is connected to the gas spring 13 through a bolt. The gas spring 13 passes downward through the blanking punch fixing plate 12, and then cooperates with the blanking pressure plate 23. During the working process, the push plate 3 moves downward, and then the gas spring 13 pushes the blanking pressure plate 23 to move downward. The blanking pressure plate 23 first contacts the raw material plate 32. In the process of further movement, the thrust of the gas spring 13 is used to press the raw material plate 32 and the die support plate 6 into position. At the same time, the blanking punch moves to the working position and performs the blanking process. During the resetting process, the gas spring lifts the blanking pressure plate 23.

[0026] The punching punch includes a positioning hole punch 24, which is used to punch a positioning hole on the raw material plate 32. The positioning hole is a circular hole. There are two positioning holes distributed along the length of the raw material plate 32. The two positioning holes correspond to a set of angle adjuster connecting plates. The punching punch also includes a base hole punch 25, an inner hole reaming punch 26 and an outer hole reaming punch 27. There are two base hole punches 25, corresponding to the left angle adjuster connecting plate and the right angle adjuster connecting plate. The inner hole reaming punch 26 and the base hole punch 25 are respectively provided with a plurality of axial ... The inner end position of the outer hole expansion punch 27 corresponds to the outer end position of the base hole punch 25, and the base hole obtained by punching is further punched and formed. A forming hole that cooperates with the positioning hole punch 24, the base hole punch 25, the inner hole expansion punch 26 and the outer hole expansion punch 27 is processed on the die support plate 6. A blanking hole 33 is formed at the lower end of the forming hole. In order to improve the rigidity of the forming hole, a high hardness coating is locally coated at the forming hole. Specifically, a cubic boron nitride (cBN) coating can be used.

[0027] In this embodiment, the positioning hole punch 24 is a cylindrical structure and is fixed by a fixing block 43. Since the outer diameters of the positioning hole punch 24 and the base hole punch 25 are relatively small, auxiliary guide blocks 44 are installed on the lower sides of the positioning hole punch 24 and the base hole punch 25. The auxiliary guide blocks 44 are made of high-speed steel and have a relatively high hardness. The auxiliary guide blocks 44 are matched with the tolerances of the corresponding positioning hole punch 24 and the base hole punch 25, and an installation groove that matches the auxiliary pressure block is processed on the lower end face of the blanking pressure plate 23.

[0028] The forming structure is used for forming the shape of the angle adjuster connecting plate by pressing. The forming structure is sequentially distributed from the feed end to the discharge end with a preforming punch 28 and a forming punch 30. Specifically, the push plate 3 is connected to a preforming punch fixing plate 15. The lower surface of the preforming punch fixing plate 15 is provided with a preforming punch 28. The die support plate 6 has a preforming die that matches the preforming punch 28. The preforming punch 28 performs a press-forming process on the outer end of the angle adjuster connecting plate. The push plate 3 is also connected to a forming punch fixing plate 14. The lower surface of the forming punch fixing plate 14 is provided with a forming punch 30. The die support plate 6 has a forming die 45 that matches the forming punch 30. The preforming punch 28 performs a press-forming process on the inner end of the angle adjuster connecting plate. The forming punch 30 performs a press-forming process on the inner end of the angle adjuster connecting plate. The low yield rate caused by the large single processing area can be avoided by performing the processing in batches, especially Specifically, when multiple punches are driven to move by the push plate 3, the degree of uneven force can be reduced, thereby improving the yield rate and the service life of the equipment. Since the forming punch 30 processes the inner side of the angle adjuster connecting plate, a forming punch reinforcement beam 29 is installed on the upper side of the forming punch 30. The forming punches 30 on both sides are stably supported by the forming punch reinforcement beam 29. Pre-forming die mounting grooves and forming die mounting grooves are processed on the die support plate 6. The pre-forming die and the forming die 45 are installed and positioned. After installation, the upper end faces of the pre-forming die and the forming die 45 are flush with the upper end face of the die support plate 6, thereby avoiding interference with the forward conveying of the raw material plate 32. The pre-forming die and the forming die 45 are both suspended and connected to the push plate 3 by the gas spring 13, thereby providing buffering during the descent process and being able to drive the pre-forming die and the forming die 45 to move upward.

[0029] A selection processing structure is installed on the rear side of the forming structure. The selection processing structure is used to select and process the manual control recliner connecting plate or the electric control recliner connecting plate. The selection processing structure includes a connection hole punch. The connection hole punch includes a connection hole punch 17 for processing the manual control recliner connecting plate and a connection hole punch 2 18 for processing the electric control recliner connecting plate. An operation hole 9 and an operation hole 2 10 that match the connection hole punch are processed on the push plate 3. The operation hole 1 9 corresponds to the manual control recliner connecting plate and the operation hole 2 10 corresponds to the electric control recliner connecting plate. A selection operating device is installed in the hole, and the selection operating device includes a detachable pressure block 46 that cooperates with the connecting hole punch. The height of the lower end of the connecting hole punch is controlled by the detachable pressure block 46, so that the corresponding connecting hole punch is made. The detachable pressure block 46 is connected to the push plate by bolts for easy operation. The detachable pressure block 46 moves with the push plate to provide a downward thrust for the corresponding connecting hole punch 17 or the connecting hole punch 2 18, thereby completing the punching process of the connecting hole. In this embodiment, a connecting hole punch fixing plate 16 is installed on the lower side of the push plate 3 to guide the connecting hole punch.

[0030] There is a cutting structure on the rear side of the selection and processing structure, which is used to cut off and remove the adjuster connecting plate from the raw material plate 32. The cutting structure includes a cutting punch fixing plate 19 connected to the push plate 3, and a cutting punch 31 is installed on the cutting punch fixing plate 19. In this embodiment, the cutting punch 31 is also connected to an auxiliary pressure block, and the cutting punch 31 passes downward through the auxiliary pressure block.

[0031] Gas springs 13 are also distributed on the side of the push plate 3 at the connecting hole punch and the truncation punch 31, which press the adjuster connecting plate processed in the previous step downward from the side, thereby stabilizing the connecting hole punching and truncation punching work.

[0032] A truncation detection structure 20 is also installed on the rear side of the truncation punch fixing plate 19. The truncation detection structure 20 includes a trigger slider 39 pointing to the angle adjuster connecting plate. The outside of the trigger slider 39 is connected to a contact switch. Specifically, a guide sleeve 38 is installed on the die support plate 6. The trigger slider 39 passes through the guide sleeve 38, the inner end points to the angle adjuster connecting plate, and the outer end cooperates with the contact switch. The contact switch selects a micro switch 40. A spring for resetting the trigger slider 39 is installed in the guide sleeve 38. At the end of the die support plate 6, A downward-sloping discharge chute 42 is processed at the end. After punching, forming, and cutting, the angle adjuster connecting plate slides from the discharge chute 42 into the collection box. When the cutting is not completed, the angle adjuster connecting plate pushes the trigger slider 39, thereby triggering the micro switch 40, triggering the alarm, and then stopping the machine for maintenance. In some embodiments, the trigger slider 39 can also be moved close to the discharge chute 42. When the angle adjuster connecting plate slides downward, it pushes the trigger slider 39 to trigger the micro switch 40, thereby counting the manufactured angle adjuster connecting plates.

[0033] A collecting box 5 is also installed on the support frame 4 , and the residual material obtained by punching falls into the support frame 4 and is then collected by the collecting box 5 inside the support frame 4 .

[0034] In this embodiment, the punching punch fixing plate 12, the preforming punch fixing plate 15, the forming punch fixing plate 14, the connecting hole punch fixing plate 16, and the truncation punch fixing plate 19 are all connected to the push plate 3 through the positioning pin 41, and then positioned, and then fastened by bolts after positioning.
