Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting device manufacturing, in particular to a bending machine used for manufacturing sandblasting devices. Background Art

[0002] In the process of manufacturing sandblasting equipment, a large number of plates are usually used. In order to make these plates adapt to different positions of the sandblasting equipment, the plates usually need to be bent. In order to facilitate the bending of these plates, the staff usually use a bending machine. The existing bending machine is usually composed of a frame, a processing platform, a bending punch and a bending die.

[0003] For example: The utility model with application number CN202122301338.9 discloses a sheet metal bending machine, which specifically includes a machine body and multiple groups of forming dies, and also includes an upper positioning assembly and a lower positioning assembly arranged on the machine body, and multiple groups of the forming dies are detachably connected between the upper positioning assembly and the lower positioning assembly, and the machine body is provided with a driving member for driving the upper positioning assembly to approach or move away from the lower positioning assembly. This application has the effect of extending the overall length of the forming die by adding a forming die between the upper positioning assembly and the lower positioning assembly, without the need to disassemble and replace the forming die, thereby improving the bending efficiency of the sheet metal and making the bending effect of the bending machine more accurate.

[0004] However, as far as the current traditional bending machines are concerned, after bending the plates, workers are usually required to manually take out the bent plates, and then place the plates to be bent into the bending machine for bending. The operation is rather cumbersome, which increases the labor intensity of the workers, affects the bending efficiency of the bending machine, and is inconvenient to use. Utility Model Content

[0007] Furthermore, the outside of the bending punch is symmetrically fixedly connected to two connecting frames; the rear parts of the two connecting frames are fixedly connected to a first transmission rack; the outside of the processing platform is symmetrically rotationally connected to two transmission gears; the two first transmission racks are respectively meshed with the front parts of the two transmission gears.

[0008] Furthermore, a second transmission rack is meshed at the rear of the two transmission gears; a control slide is fixedly connected to the outside of the two second transmission racks; the two control slides are symmetrically slidably connected in the processing platform; the ends of the two control slides are fixedly connected to a control rack; the inner sides of the two mounting plates are rotatably connected to a control gear; the two control gears are aligned with the positions of the two control racks respectively.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] During the use of the utility model, after the plate required for the manufacture of the sandblasting device is bent, the first transmission rack drives the transmission gear to rotate as the bending punch is reset, and then a series of transmission drives the placement seat to flip and automatically unload the bent plate. The operation is simple and fast, which is convenient for the staff to continuously bend the plate required for the manufacture of the sandblasting device, improves the bending efficiency of the bending machine for the plate, is more convenient to use, and effectively improves the practicability and convenience of the bending machine.

[0014] When bending the plates required for the manufacture of the sandblasting device, the staff only needs to place the bending die into the placement seat, and then turn the control screw to drive the positioning clamp to move. The movement of the positioning clamp will quickly limit and fix the placed bending die, so that the bending die can always be aligned with the position of the bending punch during the bending process, effectively improving the stability of the bending machine during the bending process.

[0029] The outside of the bending punch 102 is symmetrically fixedly connected to two connecting frames 112; the rear of the two connecting frames 112 is fixedly connected to a first transmission rack 113; the outside of the processing platform 101 is symmetrically rotatably connected to two transmission gears 114; the two first transmission racks 113 are respectively meshed with the front of the two transmission gears 114.

[0030] The rear part of the two transmission gears 114 is meshed with a second transmission rack 115; the outside of the two second transmission racks 115 is fixedly connected to a control slide 116; the two control slides 116 are symmetrically slidably connected in the processing platform 101; the ends of the two control slides 116 are fixedly connected to a control rack 117; the inner sides of the two mounting plates 118 are rotatably connected to a control gear 119; the two control gears 119 are aligned with the positions of the two control racks 117 respectively.

[0031] A control ratchet 120 is fixedly connected inside each of the two control gears 119 ; two control pawls 121 are symmetrically hingedly connected to the outside of the rotating shaft of the placement seat 104 ; and the two control pawls 121 are respectively meshed with the two control ratchets 120 .

[0032] A fixed plate 108 is fixedly connected to the upper part of the front end surface of the fixed frame 1; two guide slide bars 109 are symmetrically fixedly connected to the top surface of the fixed plate 108; a reset pressure plate 110 is slidably connected to the outside of the two guide slide bars 109; a group of support springs 111 are fixedly connected to the center of the bottom end surface of the reset pressure plate 110; the end of the support spring 111 is fixedly connected to the top surface of the fixed plate 108.

[0033] The specific usage and function of this embodiment are as follows: after the plate required for manufacturing the sandblasting device is bent, as the bending punch 102 is reset, the connecting frame 112 is driven to move, and during the movement of the connecting frame 112, the first transmission rack 113 is driven to move, and as the first transmission rack 113 moves, the transmission gear 114 meshing therewith is driven to rotate, and during the rotation of the transmission gear 114, the second transmission rack 115 is driven to move downward, and as the second transmission rack 115 moves, the control rack 117 is driven to move through the control slide 116, so that the control rack 117 slowly contacts and meshes with the control gear 119, and as the control rack 117 continues to move, the control gear 119 is driven to rotate, and the rotation of the control gear 119 drives the placement seat 104 to rotate, so that the placement seat 104 is flipped, and the bent plate on the placement seat 104 falls off for unloading, and the plate is unloaded by the control ratchet.

During the flipping process of the placement seat 104, the reset pressure plate 110 will be pressed down. After being squeezed, the reset pressure plate 110 will slide along the guide slide bar 109 and squeeze the support spring 111. After the control rack 117 moves a certain distance, it will disengage from the control gear 119. At this time, the support spring 111 loses its continuous pressure and will rebound with the action of its own elastic potential energy. As the support spring 111 rebounds, the reset pressure plate 110 will be driven to reset. As the reset pressure plate 110 is reset, the placement seat 104 will be lifted up to reset the placement seat 104. During the resetting process of the placement seat 104, the buffer pad 122 will buffer the placement seat 104.

[0036] The specific usage and function of this embodiment: when bending the plate required for manufacturing the sandblasting device, the bending die is placed in the placement seat 104, and then the control screw 106 is rotated to drive the positioning clamp 105 to move. During the movement of the positioning clamp 105, the auxiliary sliding rod 107 is set to provide guidance for the positioning clamp 105. As the positioning clamp 105 moves, the placed bending die is limited and fixed, so that the position of the bending die is aligned with the bending punch 102, and it is also convenient for the staff to rotate the bending die to adjust the bending angle of the plate.
