When the conveying plate slides to abut the storage box, the pushing plate is located in a position to completely push out the metal sheet at the bottom layer of the storage box. When the conveying plate slides to just above the fixed mold, the pushing plate is located outside the storage box as a whole, and a driving mechanism for driving the transmission gear to rotate is provided on the base.

[0007] By adopting the above technical solution, the metal sheets are stacked in the storage box in the vertical direction, and the driving mechanism drives the transmission gear to rotate and then drives the conveying plate and the push plate to slide. When the conveying plate slides in the direction close to the storage box, the push plate slides in the opposite direction at the same time and pushes the metal sheets at the bottom layer in the storage box to move. When the conveying plate slides to the position abutting the storage box, the push plate is located in a position to completely push out the metal sheets at the bottom layer of the storage box, and the metal sheets at the bottom layer of the storage box escape from the discharge port and fall into the loading port, and the supporting mechanism supports the metal sheets. When the conveying plate slides to the top of the fixed mold, the supporting mechanism releases the metal sheet onto the fixed mold, and the machine replaces manual labor to realize automatic loading of the stamping machine, which helps to save labor costs.

[0008] Optionally, the driving mechanism includes a linkage rack meshing with a transmission gear, wherein the linkage rack is fixedly connected to the stamping die. When the stamping die moves toward the fixed die, the linkage rack drives the transmission gear to rotate and then drives the conveying plate to slide toward the fixed die. When the conveying plate slides to the top of the fixed die, the linkage rack disengages from the transmission gear.

[0009] By adopting the above technical solution, when the stamping die moves toward the fixed die, it drives the interlocking rack to move in the same direction. The moving interlocking rack drives the transmission gear to rotate, and then automatically drives the driven rack and the driving rack to move during stamping, and then automatically drives the conveying plate and the push plate to slide.

[0010] Optionally, the bearing mechanism includes a bearing plate hinged on the conveying plate, the hinged rotation axis of the bearing plate is arranged parallel to the sliding direction of the conveying plate, and a first torsion spring for limiting the initial posture of the bearing plate is connected between the bearing plate and the conveying plate.

[0011] By adopting the above technical solution, the first torsion spring limits the initial posture of the supporting plate. After the metal sheet falls into the loading port, it contacts the supporting plate. The supporting plate supports the metal sheet. During stamping, the stamping die abuts against the metal sheet and pushes the metal sheet toward the fixed die, while pushing the supporting plate to rotate. The supporting plate gradually loses its supporting effect on the metal sheet and releases the metal sheet.

[0012] Optionally, the supporting mechanism includes a slide plate, a slide groove is provided on the side wall of the feeding port, the slide plate is horizontally slidably connected in the slide groove, a threaded rod for controlling and driving the sliding of the slide plate is rotatably connected on the conveying plate, a regulating gear is coaxially fixedly connected to the threaded rod, and a regulating rack is fixedly connected to the base. When the conveying plate slides in the direction close to the fixed mold, the regulating gear gradually approaches the regulating rack, and finally the regulating rack meshes with the regulating gear and drives the regulating gear and the threaded rod to rotate, driving the slide plate to slide in the direction close to the bottom wall of the slide groove. When the conveying plate is located directly above the fixed mold, the slide plate completely slides into the slide groove.

[0013] By adopting the above technical solution, the slide plate is slidably connected in the slide groove. When the slide plate completely slides into the slide groove, the slide plate loses its load-bearing function, and the metal sheet can pass through the loading port. When the slide plate is located outside the slide groove away from the bottom wall of the slide groove, it can support the metal sheet. The threaded rod can control and drive the sliding of the slide plate. In conjunction with the regulating gear and the regulating rack, the load-bearing mechanism can realize automatic switching between the two states during the stamping process.

[0014] Optionally, a second torsion spring is connected between the regulating gear and the conveying plate. When the second torsion spring is in a natural state without elastic deformation, the side of the slide plate away from the bottom wall of the slide groove is outside the slide groove.

[0015] By adopting the above technical solution, when the second torsion spring is in a natural state without elastic deformation, the slide plate is outside the slide groove away from the bottom wall of the slide groove, and when the regulating gear rotates due to vibration and bumps, it can be reset in time, which helps to automatically limit the initial state of the regulating gear.

[0016] Optionally, a limit block is provided on the base, and when the conveying plate slides to just above the fixed mold, the conveying plate abuts against the limit block.

[0017] By adopting the above technical solution, the conveyor plate needs to be moved to the top of the fixed mold to ensure the accuracy of the metal sheet feeding position, thereby ensuring the stamping accuracy. Setting a limit block can ensure that the conveyor plate will not continue to slide under the action of inertia after sliding to the position opposite to the fixed mold, which helps to improve the stamping accuracy.

[0018] Optionally, the conveying plate is made of metal material, and a magnet sheet for adsorbing and fixing the conveying plate is provided on the side of the limiting block close to the conveying plate.

[0019] By adopting the above technical solution, the magnet sheet can adsorb and fix the metal conveying plate on the limit block to prevent the position of the conveying plate from changing after the linkage rack is disengaged from the transmission gear.

[0020] Optionally, the top end of the conveying plate is provided with a guiding slope for facilitating the metal sheet to enter the loading port.

[0021] By adopting the above technical solution, the guiding slope can expand the opening area of ​​the loading port, which helps the pieces of plate to enter the loading port more smoothly.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The metal sheets are stacked in the storage box in the vertical direction. The driving mechanism drives the transmission gear to rotate and then drives the conveying plate and the push plate to slide. When the conveying plate slides in the direction close to the storage box, the push plate slides in the opposite direction at the same time and pushes the metal sheet at the bottom of the storage box to move. When the conveying plate slides to the position abutting the storage box, the push plate is located in a position to completely push out the metal sheet at the bottom of the storage box. The metal sheet at the bottom of the storage box escapes from the discharge port and falls into the loading port. The bearing mechanism supports the metal sheet. When the conveying plate slides to the top of the fixed mold, the bearing mechanism releases the metal sheet onto the fixed mold. The machine replaces manual labor to realize automatic loading of the stamping machine, which helps to save labor costs. 2. The bearing mechanism includes a slide plate. When the slide plate completely slides into the slide groove, the slide plate loses its bearing function and the metal sheet can pass through the loading port. When the slide plate is located outside the slide groove away from the bottom wall of the slide groove, it can support the metal sheet. The threaded rod can control and drive the sliding of the slide plate. In conjunction with the regulating gear and the regulating rack, the bearing mechanism can realize automatic switching between the two states during the stamping process.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] Embodiment 1: The embodiment of the present application discloses a punching machine that is easy to load.

[0034] Reference Figure 1 and Figure 2 A punching machine that is easy to load includes a base 1, a punching die 2 and a fixed die 3 are installed on the base 1, the fixed die 3 is fixedly connected to the base 1, the punching die 2 is vertically slidably connected to the base 1 and is aligned with the fixed die 3 up and down, the fixed die 3 and the punching die 2 cooperate with each other to punch metal sheets, and a hydraulic cylinder for driving the punching die 2 to slide is installed on the base 1. The relevant technology of the punching machine is the existing technology and will not be elaborated in detail. A storage box 4 is installed on the base 1, and the cross-section of the internal space of the storage box 4 is adapted to the metal sheet. The metal sheet is stacked in the storage box 4 in the vertical direction, and the metal sheet abuts against the bottom wall of the storage box 4 under the action of its own gravity. A discharge port 41 is opened on the storage box 4, and the discharge port 41 is directly opposite to one side of the fixed die 3. A push plate 5 is slidably connected to the base 1, and the sliding path of the push plate 5 passes through the bottom of the storage box 4 and can slide in and out of the storage box 4. A conveying plate 6 is slidably connected to the base 1, and a loading port 61 is provided on the conveying plate 6. The loading port 61 passes through the conveying plate 6 from top to bottom and its shape and size are adapted to the metal sheet. A bearing mechanism 7 is installed at the loading port 61 of the metal sheet. When the conveying plate 6 slides in the direction close to the storage box 4, the push plate 5 gradually slides into the storage box 4 and pushes the metal sheet at the bottom layer in the storage box 4 to move. When the conveying plate 6 slides to the position abutting against the storage box 4, the push plate 5 just pushes out the metal sheet at the bottom layer, and the metal sheet falls into the loading port 61, and the bearing mechanism 7 supports the metal sheet. The conveying plate 6 slides in the direction away from the storage box 4, and at the same time, the push plate 5 slides in the opposite direction. When the conveying plate 6 slides to the top of the fixed mold 3, the bearing mechanism 7 releases the metal sheet onto the fixed mold 3. The machine replaces the manual labor, realizes the automatic loading of the punching machine, and helps to save labor costs.

[0035] Reference Figure 1 and Figure 3 The base 1 is rotatably connected with a transmission gear 11, the conveying plate 6 is fixedly connected with a driving rack 62, the length direction of the driving rack 62 is parallel to the sliding direction of the conveying plate 6, the push plate 5 is fixedly connected with a driven rack 51, the length direction of the driven rack 51 is parallel to the sliding direction of the push plate 5, and the length direction of the driving rack 62 is parallel to the length direction of the driven rack 51, and the driving rack 62 and the driven rack 51 are respectively meshed with the symmetrical ends of the transmission gear 11. A driving mechanism 8 is installed on the base 1, which is used to drive the transmission gear 11 to rotate, thereby driving the conveying plate 6 and the push plate 5 to slide synchronously in the opposite direction.

[0036] Reference Figure 1 and Figure 3 The driving mechanism 8 includes a linkage rack 81, which meshes with the transmission gear 11 and is fixedly connected to the stamping die 2. During stamping, the stamping die 2 drives the linkage rack 81 to move in the direction close to the fixed die 3, and the linkage rack 81 drives the transmission gear 11 to rotate, thereby driving the conveying plate 6 to slide in the direction close to the fixed die 3, and at the same time drives the push plate 5 to disengage from the storage box 4. When the conveying plate 6 slides to the top of the fixed die 3, the linkage rack 81 disengages from the transmission gear 11, and the conveying plate 6 and the push plate 5 stop sliding. When the stamping is completed, the stamping die 2 drives the linkage rack 81 to move in the opposite direction, and the rotation direction of the transmission gear 11 changes, driving the conveying plate 6 to slide in the direction away from the fixed die 3, and at the same time drives the push plate 5 to enter the storage box 4 to push out the metal sheet at the bottom layer, so that the conveying plate 6 and the push plate 5 are automatically driven to slide during the stamping process.

[0037] Reference Figure 4 and Figure 5 The bearing mechanism 7 includes a bearing plate 71, which is hinged on the conveying plate 6, and the hinged rotation axis of the bearing plate 71 is set parallel to the sliding direction of the conveying plate 6. A first torsion spring 72 is connected between the bearing plate 71 and the conveying plate 6. The first torsion spring 72 limits the initial posture of the bearing plate 71. After the metal sheet falls into the loading port 61, it will contact the bearing plate 71. The gravity of the metal sheet itself is not enough to rotate the bearing plate 71. The bearing plate 71 supports the metal sheet in the loading port 61. During stamping, the stamping die 2 abuts against the metal sheet and pushes the metal sheet to move in the direction close to the fixed die 3, while pushing the bearing plate 71 to rotate. The bearing plate 71 gradually loses its supporting effect on the metal sheet and releases the metal sheet. After the stamping is completed, the first torsion spring 72 restores its initial shape and drives the bearing plate 71 to reset.

[0038] Reference Figure 3 and Figure 5, the conveyor plate 6 needs to stop in time when it moves to the top of the fixed mold 3 to ensure the accuracy of the metal sheet loading position, but the sliding of the conveyor plate 6 has a certain inertia. When it reaches the top of the fixed mold 3, the linkage rack 81 is disengaged from the transmission gear 11, and it is difficult to stop in time. Affecting the stamping accuracy. A limit block 12 is fixedly connected to the base 1. When the conveyor plate 6 slides to the top of the fixed mold 3, the conveyor plate 6 abuts against the limit block 12, which can ensure that the conveyor plate 6 will not continue to slide under the action of inertia after sliding to the position opposite to the fixed mold 3, which helps to improve the stamping accuracy.

[0039] Reference Figure 5 The punching machine will generate a certain vibration when working. After the conveying plate 6 stops sliding, it is still possible to slide in the direction away from the limit block 12 during the vibration, affecting the punching accuracy. The conveying plate 6 is made of metal material. The limit block 12 is installed with a magnet sheet 121 on the side close to the conveying plate 6, which can adsorb and fix the metal conveying plate 6 on the limit block 12 to prevent the position of the conveying plate 6 from changing after the linkage rack 81 is separated from the transmission gear 11.

[0040] Reference Figure 2 and Figure 4 A guiding slope 64 is provided at the top of the conveying plate 6 to expand the opening area of ​​the loading port 61 and help the metal sheet to enter the loading port 61 more smoothly.

[0041] The implementation principle of a punching machine that is easy to load in the embodiment of the present application is as follows: before punching, the metal sheet is cut into plates of the same size according to the standard brick size, and the cut metal sheet is stacked in the storage box 4 in the vertical direction. The punching linkage rack 81 drives the transmission gear 11 to rotate and then drives the conveying plate 6 and the push plate 5 to slide. When the conveying plate 6 slides in the direction close to the storage box 4, the push plate 5 simultaneously slides in the opposite direction and pushes the metal sheet at the bottom layer in the storage box 4 to move. When the conveying plate 6 slides to the position of abutting the storage box 4, the push plate 5 is located at a position where the metal sheet at the bottom layer of the storage box 4 is completely pushed out, and the metal sheet at the bottom layer of the storage box 4 escapes from the discharge port 41 and falls into the loading port 61, and the bearing mechanism 7 supports the metal sheet. When the conveying plate 6 slides to the top of the fixed mold 3, the bearing mechanism 7 releases the metal sheet onto the fixed mold 3, and the machine replaces the manual labor to realize the automatic loading of the punching machine, which helps to save labor costs.

[0042] Embodiment 2: The difference between the second embodiment and the first embodiment is that the structure of the supporting mechanism 7 is different. Figure 6 , Figure 7 and Figure 8The bearing mechanism 7 includes a slide plate 73, which is in the shape of a long strip. A slide groove 63 is horizontally provided on the side wall of the feeding port 61. The slide plate 73 is slidably connected to the slide groove 63. When the slide plate 73 completely slides into the slide groove 63, the slide plate 73 loses its bearing function, and the metal sheet can smoothly pass through the feeding port 61. When the side of the slide plate 73 away from the bottom wall of the slide groove 63 is located outside the slide groove 63, the passable cross-sectional area of ​​the feeding port 61 is reduced, and the slide plate 73 can prevent the metal sheet from passing through, thereby supporting the metal sheet. A threaded rod 74 is rotatably connected to the conveying plate 6. The length direction of the threaded rod 74 is set parallel to the sliding direction of the slide plate 73, and the sliding of the slide plate 73 can be controlled and driven. The threaded rod 74 is coaxially fixedly connected with a regulating gear 75, and a regulating rack 76 is fixedly connected to the base 1. When the conveying plate 6 slides in the direction close to the fixed mold 3, the regulating gear 75 gradually approaches the regulating rack 76, and finally the regulating rack 76 meshes with the regulating gear 75 and drives the regulating gear 75 and the threaded rod 74 to rotate, driving the slide plate 73 to slide in the direction close to the bottom wall of the slide groove 63. When the conveying plate 6 is located directly above the fixed mold 3, the slide plate 73 slides completely into the slide groove 63, and the metal sheet smoothly passes through the loading port 61 and falls onto the fixed mold 3, so that the automatic switching between the two states can be realized during the stamping process.

[0043] Reference Figure 7 and Figure 8 After the regulating gear 75 is separated from the regulating rack 76, it will inevitably produce certain vibrations and bumps in the process of moving with the conveying plate 6, causing the regulating gear 75 to rotate, and then causing the slide plate 73 to slide outside the manual control range. A second torsion spring 77 is connected between the regulating gear 75 and the conveying plate 6. When the second torsion spring 77 is in a natural state without elastic deformation, the side of the slide plate 73 away from the bottom wall of the slide groove 63 is outside the slide groove 63, and when the regulating gear 75 rotates due to vibrations and bumps, it can be reset in time, which helps to automatically limit the initial state of the regulating gear 75.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
