Description

Technical Field

[0001] The utility model relates to the technical field of stamping, and more specifically, to a stamping and stretching machine. Background Art

[0002] Stretching is a stamping process that uses a die to form a flat blank into an open hollow part. Stretching is one of the main stamping processes and is widely used. The stretching process can be used to make thin-walled parts in cylindrical, rectangular, stepped, spherical, conical, parabolic and other irregular shapes. If combined with other stamping processes, more complex parts can be made. Thinning and stretching processes use stamping equipment to perform stretching and forming processes on products, including: stretching, re-stretching, reverse stretching, and thinning and stretching.

[0003] At present, when materials are undergoing stamping and stretching processing, in order to avoid scratches on the product surface, people usually use stamping and stretching oil or film on the materials to provide stretching protection. The cost of film is relatively lower than that of stamping and stretching oil, but when people use film, they cannot quickly follow up on the stamping and stretching processing of the materials, and the progress of stamping and stretching is affected due to the low efficiency of film replacement. In addition, the materials need to be taken out manually after stamping and stretching, which is inconvenient to operate. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. 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.

[0023] With reference to Figures 1 - 4, the present utility model provides a stamping and stretching machine, which includes a base 1 and a frame 2 fixedly connected to the base 1. A hydraulic device 3 is fixedly connected to the frame 2. The hydraulic device 3 can be a hydraulic press. The output end of the hydraulic device 3 is fixedly connected with a lifting plate 4. The output end of the hydraulic device 3 passes through the frame 2 and is connected to the lifting plate 4. A top stretching die 5 is fixedly connected to the bottom of the lifting plate 4. At least three spring dampers 6 are fixedly connected to the base 1. A support 7 is fixedly connected to the three spring dampers 6. A bottom stamping die 8 is fixedly connected to the base 1. The bottom stamping die 8 is arranged directly below the top stretching die 5 and is located inside the support 7.

[0024] At least a pair of telescopic rods 16 are fixedly connected to the frame 2. The lifting plate 4 is fixedly connected to the pair of telescopic rods 16. The telescopic structure of the telescopic rods 16 can ensure the stability of the lifting action of the lifting plate 4.

[0025] Specifically, by placing the processing material on the support 7 and starting the hydraulic device 3, the hydraulic device 3 can drive the top stretching die 5 to descend through the lifting plate 4. The top stretching die 5 can extrude the processing material on the support 7. By using the compressibility of the spring dampers 6, the descent of the support 7 enables the bottom stamping die 8 to push the processing material into the top stretching die 5 for stretching treatment.

[0026] Rotating support structures 9 are arranged on both sides of the lifting plate 4. A roller body 10 is detachably connected to each rotating support structure 9. A protective film 11 is wound around a pair of roller bodies 10. The protective film 11 passes through the space between the top stretching die 5 and the support 7. A servo motor 12 for driving the roller body 10 to rotate is arranged on one of the rotating support structures 9. The servo motor 12 is a self-locking motor.

[0027] The rotating support structure 9 includes an assembly frame 91 fixedly connected to the side of the lifting plate 4 and a pair of rotating discs 92 rotatably connected to the end side of the assembly frame 91 through a rotating shaft. The roller body 10 is detachably connected to the pair of rotating discs 92 by bolts. The servo motor 12 is fixedly connected to the assembly frame 91, and the output end of the servo motor 12 passes through the assembly frame 91 and is fixedly connected to the rotating shaft end of one of the rotating discs 92. In this application, the roller body 10 is arranged in an I-shaped structure, and the end of the roller body 10 can be connected to the rotating disc 92 by bolts, so as to meet the detachable property of the roller body 10, thereby facilitating the replacement of the protective film 11 on the roller body 10.

[0028] Specifically, with a certain feeding interval reserved between the upper stretching die 5 and the support base 7, at this time, the protective film 11 on the pair of roller bodies 10 can be arranged to pass through the feeding interval. By placing the processing material on the support base 7, when the upper stretching die 5 descends, the synchronous descent of the roller bodies 10 can make the protective film 11 cover the processing material, so that the processing material can obtain anti-scratch protection during stamping and stretching; since the servo motor 12 can drive one of the roller bodies 10 to rotate, the winding action of the roller body 10 can wind up the protective film 11, and the other roller body 10 can unwind the protective film 11, so that when the upper stretching die 5 is opened, the protective film 11 can be conveniently replaced.

[0029] An optoelectronic detection component 13 is arranged on the frame 2 and the lifting plate 4, a blanking rotating rod 14 is arranged on the base 1, and a blanking transmission structure 15 for driving the blanking rotating rod 14 to rotate is arranged on one of the rotating support structures 9.

[0030] The optoelectronic detection component 13 includes an optoelectronic emitter 131 suspended at the inner bottom of the frame 2 and an optoelectronic receiver 132 fixedly connected to the lifting plate 4. The optoelectronic receiver 132 is used to receive the emission signal of the optoelectronic emitter 131. In this application, the optoelectronic receiver 132 and the optoelectronic emitter 131 can be electrically connected to the servo motor 12 through an external controller. When the optoelectronic receiver 132 receives the emission signal of the optoelectronic emitter 131, that is, when the upper stretching die 5 is in the open mold state, the servo motor 12 can drive and control the protective film 11 to be wound and replaced.

[0031] The blanking rotating rod 14 is rotatably connected to the base 1 through a rotating shaft. A rubber plate 17 is fixedly connected to one side of the blanking rotating rod 14. In this application, the blanking rotating rod 14 is arranged in a Z-shaped structure, so that it can conveniently rotate around the transmission end of the blanking transmission structure 15. The rubber plate 17 can increase the elastic protection of the formed product in contact with the blanking.

[0032] The blanking transmission structure 15 includes a fixing plate 151 fixedly connected to one of the mounting frames 91, a rotating tube 152 rotatably connected to the fixing plate 151 through a bearing, a transmission rod 153 inserted into the rotating tube 152, a gear one 154 fixedly connected to the outer side of the rotating tube 152, and a gear two 155 meshed with the gear one 154. The gear two 155 is fixedly connected to the rotating shaft end of one of the rotating disks 92. In this application, the transmission rod 153 is arranged in a cross structure.

[0033] Specifically, when the upper stretching die 5 descends to extrude the processing material on the support 7, at this time, the rotating tube 152 can slide down in an inserted manner on the transmission rod 153, so as to ensure the effectiveness of the transmission of the blanking transmission structure 15 when the upper stretching die 5 moves. After the upper stretching die 5 is opened, when the servo motor 12 drives the protective film 11 to wind up, at this time, the rotation of the rotating disk 92 can drive the second gear 155 to rotate. The second gear 155 is meshed and connected to the first gear 154 to drive the rotating tube 152 to rotate. The rotation of the rotating tube 152 can drive the blanking rotating rod 14 to rotate through the transmission rod 153. Then, when the blanking rotating rod 14 passes above the support 7, it can push the products subjected to stamping and stretching for blanking.
