Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal manufacturing equipment, and in particular relates to a cutting machine blanking device used for sheet metal manufacturing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly.

[0003] Since large sheet metal is heavy and the height difference between the cutting surface and the ground is large, the load is large when unloading it after cutting, which makes it difficult to unload the sheet metal using conventional sheet metal cutting equipment.

[0004] To this end, we propose a cutting machine unloading device for sheet metal manufacturing to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that conventional sheet metal cutting equipment is difficult to cut materials, and proposes a cutting machine cutting device for sheet metal manufacturing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cutting machine unloading device for sheet metal manufacturing includes a base, the front part of the base is rotatably connected to a roller, the rear part of the roller is equipped with a universal wheel, the rear inner end of the base is fixedly connected to a choke valve, the choke valve runs through the base, the base is fixedly connected to a guide column, the upper end of the choke valve is fixedly connected to a sealing cylinder, the internal spaces of the choke valve and the sealing cylinder are connected, a shovel seat is slidably installed on the guide column, the rear part of the shovel seat is fixedly connected to a piston rack, and the rear sliding seal of the piston rack is installed in the sealing cylinder. Pull the piston rack upward, then push the device forward, use the shovel seat to scoop up the sheet metal, and then pull the device backward, use the downward weight of the sheet metal to act on the shovel seat, so that the shovel seat acts on the piston rack, so that the piston rack slides downward along the sealing cylinder, and use the choke valve to increase the air resistance, reduce the exhaust speed of the sealing cylinder, and slowly lower the sheet metal, so as to facilitate unloading.

[0008] Preferably, the upper end of the sealing cylinder is fixedly connected with a guide frame, which guides the piston frame to slide, thereby improving the stability of the piston frame in the up and down sliding direction.

[0009] Preferably, a booster spring is fixedly connected between the piston frame and the guide frame, and the initial elastic force of the booster spring is equal to the gravity of the shovel seat and the piston frame. The booster spring is used to provide an upward elastic force for the shovel seat, thereby reducing the influence of the gravity of the piston frame and the shovel seat, and facilitating the hand-pulling of the piston frame to restore the position of the piston frame and the shovel seat.

[0010] Preferably, the air blocking valve comprises a valve block and a valve housing, the upper end of the valve block is hollowed out to form an exhaust hole, and the valve block is slidably installed in the valve housing. When the piston rack is lifted upward, the gas acts on the valve block upward, so that the ventilation cross-section of the valve housing is increased, and the gas quickly enters the sealing cylinder. When the valve housing is exhausted, the valve block is used to block the lower space of the valve housing, so that the gas can only be exhausted to the outside through the exhaust hole, which is convenient for reducing the descending speed of the piston rack and the shovel seat.

[0011] Preferably, the piston rack comprises a connecting rack and a piston, and the upper end of the connecting rack is fixedly connected to the piston. Pulling the piston upwards causes the lower part of the sealing cylinder to inhale air, and vice versa, causes the lower part of the sealing cylinder to exhaust air, which facilitates the sealing cylinder to inhale or exhaust air.

[0012] Preferably, the piston rack further comprises a handle, and the handle is fixedly connected to the connecting frame, so that the piston rack can be conveniently operated by hand through the handle.

[0013] Preferably, the shovel seat comprises a shovel plate and a sliding sleeve, wherein the sliding sleeve is symmetrically fixedly connected to the rear of the shovel plate. The sliding sleeve is used to slide along the guide column to increase the stability of the shovel plate in the lifting state.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Pull the piston frame upward, then push the device forward, use the shovel seat to shovel the sheet metal, and then pull the device backward. Use the downward weight of the sheet metal to act on the shovel seat, so that the shovel seat acts on the piston frame, so that the piston frame slides downward along the sealing cylinder, and use the air blocking valve to increase the air resistance, reduce the exhaust speed of the sealing cylinder, and slowly lower the sheet metal, so as to facilitate material unloading.

[0016] 2. Use the booster spring to provide an upward elastic force for the shovel seat, reduce the gravity effect of the piston frame and the shovel seat, and facilitate the hand-pull piston frame to restore the position of the piston frame and the shovel seat.

[0017] 3. When the piston rack is lifted upward, the gas acts on the valve block upward, increasing the ventilation cross-section of the valve housing and allowing the gas to quickly enter the sealing cylinder. When the valve housing is exhausted, the valve block is used to block the lower space of the valve housing so that the gas can only be exhausted to the outside through the exhaust hole, which is convenient for reducing the descending speed of the piston rack and the shovel seat.
