Description

Technical Field

[0001] The present invention relates to the field of stamping technology, in particular to a switch cabinet guide rail multi-station punching and forming integrated die. Background Art

[0002] Switch cabinet guide rails are basic structural parts used to fix components in power equipment. They must meet requirements such as high-precision hole positions and forming strength. Traditional processing requires multiple processes such as punching, bending, and forming, and there are repeated positioning errors. The industry trend is towards integration and automation. The existing single-station molds are difficult to meet the needs of mass production. The mold is used to process the shape of an object through the physical state of the molding material. It is known as the "mother of industry". During the processing, the mold uses the pressure of the press to emboss the workpiece to be processed, and then uses the punching device to open corresponding through holes on the surface of the workpiece to be processed, so that the workpiece meets the manufacturing requirements of different products.

[0003] Traditional switch cabinet guide rail punching dies can usually only perform a single punching operation. Before punching, the metal sheet needs to be punched into a rectangle. The single-station split mold leads to time-consuming material turnover. In addition, there is a need to process metal sheets of multiple sizes during the production process of switch cabinet guide rails. In order to adapt to the stamping of multiple models of switch cabinet guide rails, multiple stamping machines or replacement of stamping dies are usually used to solve this problem. The configuration of multiple stamping machines will greatly increase production costs, and the method of constantly replacing stamping dies will take time to replace and debug the mold (about 2 hours per time), which restricts the flexibility of the production line. In view of this, we propose a multi-station punching and forming integrated mold for switch cabinet guide rails. Summary of the Invention

The segmented punching device 5 first squeezes the split punching die head 8 directly below, and then sequentially performs the stamping, shaping, and punching operations on the metal sheet on the fan-shaped bottom die 10, thereby achieving the goal of stamping and punching the metal sheet on the punching machine 1 at a single station, reducing the time-consuming metal sheet turnover problem caused by the split die and improving the overall working efficiency of the die. By means of three sets of fan-shaped and corresponding separate stamping dies 8 and fan-shaped bottom dies 10 upper die seats, the three sets of fan-shaped separate stamping dies 8 and fan-shaped bottom dies 10 are rotated and switched by using a switching device 12, thereby achieving the effect of stamping and punching three different types of metal plates. The switching method of the multi-station stamping mechanism can improve the applicability and practicality of the overall stamping machine 1, avoiding the time-consuming and labor-intensive disassembly and replacement of traditional molds and the high cost of multi-station stamping mechanisms.

[0022] In this embodiment, the separate stamping die head 8 includes a stamping die 81, which is fixedly connected to the telescopic end of the spring telescopic rod 7. The interior of the stamping die 81 is elastically connected to a punching die 82 via a spring, and the punching die 82 is fixedly connected to a pressed plate 84 via a connecting column 83. The surface of the punching die 82 is slidably connected to the inner wall of the stamping die 81, and the surface of the pressed plate 84 is slidably connected to the inner wall of the stamping die 81. There are three groups of stamping dies 81, punching dies 82 and die bases distributed in a fan shape. Each individual stamping die 81 corresponds to a corresponding punching die 82 and die base, thereby realizing the stamping work of three different types of metal plates. The switching method of the multi-station stamping mechanism can improve the applicability and practicality of the overall stamping machine 1, avoiding the time-consuming and labor-intensive disassembly and replacement of traditional dies and the high cost of multi-station stamping mechanisms. The segmented stamping device 5 first squeezes the stamping die 81 directly below, and the stamping die 81 directly below gradually applies force to the fan-shaped bottom die 10 during the overall downward movement, so as to stamp and shape the metal sheet on the die base directly below the stamping die 81 on the fan-shaped bottom die 10, thereby achieving the effect of automatically punching the metal sheet into a rectangle.

[0023] Furthermore, the arm connector 9 includes a connecting arm 91, the surface of the connecting arm 91 is fixedly connected to the surface of the multi-station rotating shaft 6, a yield base 92 is fixedly connected to the connecting arm 91, the interior of the yield base 92 is elastically connected to a T-block 93 through a damping spring shock absorber, the bottom of the T-block 93 is fixedly connected to the fan-shaped bottom mold 10 through an arc plate 94, and the surface of the T-block 93 is slidably connected to the interior of the yield base 92. By designing the T-block 93, the damping spring shock absorber on the T-block 93 is used to achieve buffering and shock absorption of the fan-shaped bottom mold 10 as a whole.

[0024] Furthermore, the segmented stamping device 5 includes a pressing base 51 and a guide base 55 fixedly mounted on the top base 3. The top of the pressing base 51 is fixedly mounted on the output shaft of the hydraulic cylinder 4. The interior of the pressing base 51 is elastically connected to a slider 52 via a spring. Rollers 53 are fixedly connected to both sides of the slider 52. The bottom of the slider 52 is fixedly connected to a stamping wheel 54. The surface of the slider 52 is slidably connected to the interior of the pressing base 51. The period during which the hydraulic cylinder 4 drives the pressing base 51 downward is divided into two working sections. The first working section is when it just moves downward. At this time, the pressing base 51 drives the stamping wheel 54 through the slider 52 to squeeze the stamping die 81 directly below. During the period during which the stamping die 81 directly below moves downward as a whole, it gradually applies force to the fan-shaped bottom die 10, thereby stamping and shaping the metal sheet on the die base directly below the stamping die 81 on the fan-shaped bottom die 10, thereby achieving the effect of automatically stamping the metal sheet into a rectangle. During the first working section, the downward sliding The roller 53 on the block 52 gradually contacts the guide seat 55 and is restricted by the extrusion of the inclined surface of the guide seat 55, and gradually moves toward the pressed plate 84. When the punching wheel 54 moves to the pressed plate 84, the pressing base 51 switches to the second working section. At this time, the pressing base 51 drives the punching wheel 54 to squeeze the pressed plate 84 through the slider 52. The pressed plate 84 applies pressure to the punching die 82 through the connecting column 83. The punching die 82 is ejected from the stamping die 81 and punches the metal plate after stamping.

[0025] In addition, the switching device 12 includes a mounting base 121, the bottom of the mounting base 121 is fixedly mounted on the punching machine 1, and a control motor 122 is fixedly mounted on the mounting base 121. The output shaft of the control motor 122 is fixedly connected to a worm 123, and the surface of the worm 123 is engaged with a worm wheel 124. The interior of the worm wheel 124 is fixedly connected to the surface of the multi-station shaft 6. When it is necessary to stamp metal plates of different sizes, the control motor 122 is driven to work as required, and the output shaft of the control motor 122 engages the worm wheel 124 through the worm 123 to drive the multi-station shaft 6 to rotate, thereby achieving the effect of rotation switching of three groups of fan-shaped distributed stamping dies 81, punching dies 82 and die bases. At the same time, the engagement of the worm wheel 124 and the worm 123 is self-locking, which can ensure the stability of the multi-station shaft 6 after the angle is adjusted.

[0026] In addition, the adaptive clamping device 13 includes an automatic clamping seat 131, the bottom of the automatic clamping seat 131 is elastically connected to the surface of the punching machine 1 through a spring, the top of the automatic clamping seat 131 is fixedly connected to a connecting frame 132, the connecting frame 132 is fixedly connected to a spring telescopic rod 2 133, the end of the spring telescopic rod 2 133 away from the connecting frame 132 is fixedly connected to a connecting rod 134, and the end of the connecting rod 134 is fixedly connected to the pressing base 51 (as shown in FIG. Figure 9 As shown), the surface of the connecting rod 134 is slidably connected to the inside of the top seat 3, and the connecting frame 132 is located directly above the automatic clamping seat 131 and has an air groove. When the hydraulic cylinder 4 drives the pressing base 51 to punch up and down, the pressing base 51 transmits the corresponding power through the connecting rod 134 to the spring telescopic rod 2 133. During the contraction movement of the spring telescopic rod 2 133, positive and negative pressures are applied to the connecting frame 132, thereby facilitating the rapid circulation of air on the metal plate surface of the automatic clamping seat 131 driven by positive and negative pressures, thereby achieving the effect of wind cleaning. A linkage arc block 135 is fixedly connected to one side of the sector bottom die 10 near the automatic clamping seat 131. The surface of the linkage arc block 135 is slidably connected to the side of the automatic clamping seat 131. The sector bottom die 10 and the automatic clamping seat 131 are connected by the linkage arc block 135, so that the sector bottom die 10 and the automatic clamping seat 131 can maintain synchronous operation, thereby preventing the sector bottom die 10 from being misaligned with the automatic clamping seat 131 after being subjected to the punching pressure, which in turn causes the metal plate to be misaligned and deformed. Limiting plates 136 are fixedly connected to both sides of the automatic clamping seat 131 on the punching machine 1, and the surface of the automatic clamping seat 131 is slidably connected to the surface of the limiting plates 136.

[0027] It is worth noting that a stamping pad 14 is fixedly installed below the fan-shaped bottom die 10 on the stamping machine 1, and a discharge cavity is provided on the top of the stamping pad 14 for centrally collecting the metal sheet waste after stamping.

[0028] When the multi-station punching and forming integrated die for the switch cabinet guide rail of the present invention is in use, the metal sheet to be processed is placed on the automatic clamping seat 131. The automatic clamping seat 131 is an automatic clamp in the prior art, which is used to position and clamp the metal sheet, and the hydraulic cylinder 4 is started to drive the pressing base 51 to move downward as a whole. The pressing base 51 is divided into two working sections during the downward movement. The first working section is when it just moves downward, which is the first working section. At this time, the pressing base 51 drives the stamping wheel 54 to squeeze the stamping die 81 directly below through the slider 52. During the downward movement of the stamping die 81 directly below, the force is gradually applied to the fan-shaped bottom die 10, so as to stamp and shape the metal sheet on the die seat directly below the stamping die 81 on the fan-shaped bottom die 10, thereby achieving the effect of automatically stamping the metal sheet into a rectangle. During the first working section, the roller 53 on the downward sliding block 52 gradually contacts the guide seat 55, and is squeezed and restricted by the inclined surface of the guide seat 55, and gradually moves toward the pressed plate 84. When the stamping wheel 54 moves to When the pressed plate 84 is on the pressing plate 84, the pressing base 51 switches to the second working section. At this time, the pressing base 51 drives the punching wheel 54 to squeeze the pressed plate 84 through the slider 52, and the pressed plate 84 applies pressure to the punching die 82 through the connecting column 83. The punching die 82 is pushed out of the stamping die 81 and punches the metal plate after stamping, thereby achieving the stamping and punching of the metal plate on the stamping machine 1 in one station, reducing the problem of time-consuming metal plate turnover caused by the split die, and improving the working efficiency of the entire die. At the same time, since three groups of fan-shaped stamping dies 81, punching dies 82 and die bases are set, each individual stamping die 81 corresponds to the corresponding punching die 82 and die base, and then the three different types of metal plates can be stamped. The switching method of the multi-station stamping mechanism can improve the applicability and practicality of the overall stamping machine 1, and avoid the time-consuming and labor-intensive independent disassembly and replacement of traditional dies and the high cost of multi-station stamping mechanisms. When it is necessary to stamp metal plates of different sizes, the motor 122 is driven and controlled to work according to the requirements. The output shaft of the control motor 122 drives the multi-station shaft 6 to rotate through the worm 123 engaging the worm gear 124, thereby achieving the effect of rotation and switching of three groups of fan-shaped distributed stamping dies 81, punching dies 82 and die bases.By designing the T-block 93 and utilizing the damping spring shock absorber on the T-block 93, the overall buffering and shock absorption of the fan-shaped bottom mold 10 is achieved, and the fan-shaped bottom mold 10 and the automatic clamping seat 131 are connected by the linkage arc block 135, so that the fan-shaped bottom mold 10 and the automatic clamping seat 131 can keep working synchronously, thereby avoiding the problem of the fan-shaped bottom mold 10 being misaligned with the automatic clamping seat 131 after the punching pressure, which then causes the metal plate to be misaligned and deformed. By setting the connecting frame 132, the connecting frame 132 is provided with an air groove directly above the automatic clamping seat 131. Whenever the hydraulic cylinder 4 drives the pressing base 51 to punch up and down, the pressing base 51 transmits the corresponding power to the spring telescopic rod 2 133 through the connecting rod 134. During the contraction movement of the spring telescopic rod 2 133, positive and negative pressures are applied to the connecting frame 132, thereby facilitating the rapid circulation of air on the surface of the metal plate on the automatic clamping seat 131 driven by positive and negative pressure, thereby achieving the effect of wind cleaning.
