Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment accessory processing, and in particular relates to a stamping device for electrical equipment accessory processing. BACKGROUND

[0002] In the processing of electrical equipment metal accessories, V-shaped bending is a common forming process, which is widely used in the manufacturing of sheet metal parts, supports, housings and other accessories. The traditional V-shaped bending processing is usually completed by using an upper and lower mold cooperation method, in which the V-shaped groove angle of the lower mold directly affects the angle accuracy of the bending forming. However, in actual production, since different products have different requirements for the bending angle, the operator needs to frequently adjust the V-shaped groove angle of the lower mold to adapt to different processing requirements.

[0003] At present, the common adjustment method is manual adjustment, that is, by replacing lower molds of different angles or manually adjusting the opening angle of the mold to achieve the adjustment. However, manual adjustment has the following problems. First, the precision is low, and manual operation is easy to introduce errors, which leads to deviation of the bending angle from the design requirements, affecting the product quality. Second, the efficiency is low, and each adjustment needs to stop and recalibrate, which increases the production time and reduces the processing efficiency. Finally, the adaptability is poor, and for small batch, multi-variety flexible production requirements, frequent adjustment of the mold is difficult to meet the requirements of rapid changeover. Although some existing technologies have some automatic adjustment schemes, such as using a servo motor to drive the mold angle change, there is still a lack of real-time monitoring and feedback mechanism for the bending angle, which makes it difficult to ensure the bending accuracy. Therefore, the present application provides a stamping device for electrical equipment accessory processing to meet the needs. SUMMARY

[0042] The two sides of the fixed frame 1 are rotatably connected with symmetrically distributed rollers, the upper die 3 is located above the rollers, and the lower die 6 is located below the rollers, the rollers arranged on the two sides of the fixed frame 1 are used for supporting the accessory raw materials, and can assist the accessory raw materials in conveying displacement in the fixed frame 1 through rolling of the rollers, after stamping and bending processing is completed, the processed accessories are output together with the plate materials where the accessories are located, an installation assembly is arranged, which is used for installing the laser profiler 14 in the lifting seat 4, the installation assembly is connected with the lifting seat 4, and the installation assembly is arranged so that the laser profiler 14 moves up and down in the lifting seat 4, then avoids the laser profiler 14 when the upper die 3 and the lower die 6 cooperate to perform stamping processing, and rises after the processing is completed, so that the laser profiler 14 is prevented from being impacted by other structures in the stamping process, and the laser profiler 14 is prevented from being damaged, and the rising process can enable the laser profiler 14 to more comprehensively identify the end face of the accessory after stamping and bending, so that the detection of the laser profiler 14 is more stereoscopic, and data is more accurate; a protection assembly is arranged, which is used for protecting the laser profiler 14 in the stamping and bending process, the protection assembly is connected with the installation assembly, and the protection assembly is arranged on one hand to protect the laser profiler 14 in cooperation with the installation assembly in the stamping and bending process, and on the other hand can also realize automatic cleaning of a scanning area of the laser profiler 14, so that dust or debris generated in metal processing is prevented from appearing outside the laser profiler 14 in a long-term use process, the detection accuracy of the laser profiler 14 is further ensured, and the control of product quality by the stamping device is improved.

[0043] In the embodiment, as shown in Figures 1 to 3 The rotating rods 9 are symmetrically distributed in the servo motors 5, one end of the rotating rod 9 is fixedly connected with a driving shaft of the servo motor 5, the other end of the rotating rod 9 is rotatably connected with the lifting seat 4 through a bearing, and the rotating rod 9 is fixedly connected with the lower die 6 through the connecting seat 7. The connecting seat 7 is L-shaped. The connecting relationship between the rotating rod 9 and the servo motor 5 enables the servo motor 5 to drive the rotating rod 9 to rotate through the driving shaft when the servo motor 5 works, and then drives the connecting seat 7 and the lower die 6 to deflect on the inner side of the lifting seat 4 through the rotation of the rotating rod 9, so as to realize adjustment of the included angle between the lower dies 6. The L-shaped structure of the connecting seat 7 enables the rotating rod 9 to have a larger spacing in the lifting seat 4, thereby providing sufficient space for the laser profiler 14 arranged in the lifting seat 4, and facilitating the laser profiler 14 to detect the bending angle of the accessory. The servo motors 5 are staggered and arranged on the two sides of the lifting seat 4, two servo motors 5 are fixedly connected with two rotating rods 9 respectively, and the servo motors 5 are separately controlled, so that the included angle range and the included angle form of the lower dies 6 are more flexible to adjust, and some more complex bending angle requirements can be met.

[0044] In the embodiment, as shown in Figures 3 to 4 and Figures 6 to 11As shown, the mounting assembly comprises sleeve sockets 10 symmetrically distributed on the inner side walls of the lifting seat 4, movable seats 11 sleeved in the sleeve sockets 10, cavities in the sleeve sockets 10 for the movable seats 11 to move up and down, laser profile meters 14 mounted on the movable seats 11, limit blocks 20 arranged at the top ends of the sleeve sockets 10, guide grooves 18 on the two sides of the movable seats 11 matched with the shapes of the limit blocks 20, and springs 19 uniformly distributed and fixedly connected between the bottom ends of the movable seats 11 and the sleeve sockets 10. The movable seats 11 move up and down in the sleeve sockets 10 along the guide of the guide grooves 18 and the limit blocks 20, so as to ensure the trajectory of the relative sliding between the movable seats 11 and the sleeve sockets 10 and indirectly ensure the stability of the laser profile meters 14 during the lifting process. The movable seats 11 are used for mounting and fixing the laser profile meters 14, and the lifting movement of the movable seats 11 in the sleeve sockets 10 will synchronously drive the laser profile meters 14 to move up and down in the lifting seat 4, so as to change the relative position between the laser profile meters 14 and the lower die 6. During the pressing process of the upper die 3, the top end of the movable seat 11 will be extruded, so that the movable seat 11 is retracted into the sleeve socket 10, and the laser profile meter 14 is lowered along with the movable seat 11. When the upper die 3 cooperates with the lower die 6 to stamp and bend, the laser profile meter 14 is lowered to avoid and protect the laser profile meter 14. When the movable seat 11 is pressed by the upper die 3 and is lowered, the spring 19 will be synchronously compressed and accumulate elastic potential energy. After the upper die 3 is reset and the pressure on the movable seat 11 is removed, the movable seat 11 can be reset and synchronously drive the laser profile meter 14 to reset. The laser profile meter 14 can pass through the end face of the stamped and bent accessory during the resetting process, so as to more comprehensively realize the detection of the bending angle of the end face of the accessory, and then control the device to pass the processed accessory or adjust the included angle of the lower die 6, so as to ensure the accuracy of the whole device during work.

[0045] The top end of the movable seat 11 is provided with a protrusion 12, a first limiting hole 13 matched with the shape of the bottom end of the upper die 3 is arranged in the middle part of the protrusion 12, the two ends of the upper die 3 extend to the position flush with the back surface of the movable seat 11, and the protrusion 12 at the top end of the movable seat 11 is contacted when the upper die 3 presses the movable seat 11. The bottom end of the upper die 3 can be embedded in the first limiting hole 13 on the protrusion 12, so as to prevent the dislocation of the upper die 3 during the pressing process of the movable seat 11. The position to which the two ends of the upper die 3 extend can ensure that the upper die 3 can contact the protrusion 12 and ensure the pressing effect of the upper die 3. The upper die 3 can stably and reliably drive the movable seat 11 and the laser profile meter 14 to move downward during the stamping and bending operation of the accessory raw material, so as to ensure the position adjustment effect of the mounting assembly on the laser profile meter 14 during the stamping process.

[0046] In the embodiment, asFigures 4 to 5 And Figures 7 to 11 As shown in the figure, the protection assembly includes a protective plate 15 fixedly connected to the top of the sleeve seat 10 and a protective ring 23 fixedly connected to the movable seat 11. The protective plate 15 is provided with a cleaning cloth 21 matched with the shape of the laser profiler 14. The cleaning cloth 21 is fixedly connected to the protective plate 15 by magic tape, which is convenient to disassemble and replace. Regular replacement can better achieve the cleaning and protection of the laser profiler 14. The top end of the protective plate 15 is provided with a second limiting opening 16 matched with the shape of the bottom of the upper die 3. The top end of the protective plate 15 is provided with an avoiding surface 22. When the laser profiler 14 is lowered to the lowest point with the movable seat 11, the bottom end of the upper die 3 is inserted into the first limiting opening 13 on the protruding block 12 and is in butt joint with the second limiting opening 16 on the protective plate 15. The second limiting opening 16 is used to assist the positioning of the upper die 3 and the movable seat 11. A weakening groove 17 is arranged at the connection between the protective plate 15 and the sleeve seat 10. The weakening groove 17 makes the thickness of the protective plate 15 thinner at the weakening groove 17, so that the protective plate 15 is more likely to bend and deform at the weakening groove 17 under external force. When the laser profiler 14 is lowered to the lowest point with the movable seat 11, the position of the laser profiler 14 corresponds to the position of the cleaning cloth 21 on the protective plate 15. The cleaning cloth 21 protrudes from the outside of the protective plate 15. When the position of the laser profiler 14 corresponds to the position of the cleaning cloth 21, the cleaning cloth 21 can contact the laser profiler 14. By the lifting of the laser profiler 14, the detection area of the laser profiler 14 can be wiped and cleaned from the outside of the laser profiler 14, so as to ensure the cleanliness of the laser profiler 14 and further ensure the detection accuracy of the laser profiler 14. Influenced by the protruding structure of the cleaning cloth 21, the cleaning cloth 21 can transmit the force to the protective plate 15 after being extruded from the outside of the movable seat 11, so as to drive the protective plate 15 to bend and deform at the weakening groove 17 until the laser profiler 14 moves to the cleaning cloth 21. The protective plate 15 is reset under the action of its own elasticity. During the lowering of the laser profiler 14, that is, during the stamping and bending operation of the upper die 3 and the lower die 6 cooperating into the accessory, the laser profiler 14 can also be shielded by the protective plate 15, so as to form effective protection for the laser profiler 14 during the stamping process of the device.

[0047] The protective ring 23 is annularly arranged outside the laser profiler 14, the protective ring 23 is a hollow structure, and the outer part of the protective ring 23 close to the movable seat 11 is provided with a recessed area 24, the avoidance surface 22 is arranged on one side of the top end of the protective plate 15 close to the avoidance surface 22, the arrangement of the avoidance surface 22 can increase the gap between the top end of the protective plate 15 and the movable seat 11, facilitate the extrusion of the protective ring 23 to the protective plate 15 during the lifting process of the movable seat 11, the arrangement of the protective ring 23 can surround the cleaning cloth 21 and the laser profiler 14 when the cleaning cloth 21 contacts the laser profiler 14, so as to fill the gap between the cleaning cloth 21 and the laser profiler 14, further strengthen the protection effect of the protective assembly on the laser profiler 14, and the debris generated in the stamping process will fall into the recessed area 24 on the protective ring 23, and even if the cleaning cloth 21 is separated from the protective ring 23 during the subsequent resetting process of the laser profiler 14 with the movable seat 11, the debris and dust will not directly fall on the position where the laser profiler 14 is located, which can further ensure the cleanliness of the working environment of the laser profiler 14 and perfect the whole device scheme.
