Description

Technical Field

[0001] The utility model relates to an automatic press, in particular to an automatic press which is convenient for unloading materials and belongs to the technical field of automatic presses. Background Art

[0002] Press is the abbreviation of press, hydraulic press and oil press. Press refers to a molding machine used for industrial products to be molded by pressure. It generally uses hydraulic pressure, so it is also called oil press. The product is punched by the top needle, and the material is pushed out by the push plate after punching.

[0003] The current automatic press has certain defects when in use. When the automatic press is in use, the stamped parts are pushed out through the push plate. There is a lot of dust in the working environment of the automatic press. When the automatic press is working, not only will there be a lot of dust falling on the push mechanism, but also there will be a certain amount of waste chips when the stamped parts are ejected. These waste chips and dust falling on the push mechanism will not only easily cause the push plate to be blocked, but also cause the stamped parts to be unable to be ejected, resulting in the automatic press being unable to unload materials. Therefore, an automatic press that is easy to unload materials is now proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides an automatic press that is easy to unload materials, which overcomes the shortcomings of the prior art and aims to solve the problem that the push plate and stamping parts of the existing automatic press are blocked by dust and waste during the unloading process, resulting in the inability to unload materials.

The upper side surface of the fixed seat is located at a position behind the pushing groove, and a pushing mechanism is fixedly installed on the driving end of the pushing groove, and a negative pressure chip removal mechanism is provided at a position on the upper side surface of the fixed seat at one side of the pushing mechanism, and a telescopic hose is fixedly connected to the front side of the negative pressure chip removal mechanism. The absorption cover is fixedly connected to the absorption cover in the pushing groove, and the absorption cover is located on the driving end of the pushing mechanism. The negative pressure chip removal mechanism generates negative pressure suction and absorbs waste chips and dust in the pushing groove through the telescopic hose and the absorption cover.

[0007] Through the above technical scheme, the bracket fixes the automatic press, and the upper die is installed on the driving end of the punching hydraulic cylinder. When the punching hydraulic cylinder is driven, the ejector at the bottom of the upper die punches the workpiece placed on the lower die. The workpiece after punching is ejected from the ejection hole under the ejection of the ejector rod of the lower die, and then the pushing mechanism pushes the ejected workpiece forward to realize pushing. During the pushing process of the pushing mechanism, the negative pressure chip removal mechanism generates negative pressure suction, thereby generating suction on the absorption cover to absorb dust and waste chips on the pushing trough, thereby avoiding blockage of the pushing mechanism and the workpiece by waste chips, and facilitating the unloading work.

[0008] As a preferred technical solution of the present application, a material removal plate is fixedly connected to the front side of the fixing seat, and the upper end of the material removal plate and the bottom of the pushing groove are located in the same plane.

[0010] As a preferred technical solution of the present application, the pushing mechanism includes a fixed plate, a pushing hydraulic cylinder is fixedly installed on the rear side of the fixed plate, and a pushing plate is fixedly connected to the piston rod of the pushing hydraulic cylinder.

[0011] Through the above technical solution, the pusher hydraulic cylinder drives the pusher plate on the piston rod to move, and the pusher plate moves on the pusher groove, so that the pusher plate pushes out the ejected stamping parts to realize the unloading work.

[0012] As a preferred technical solution of the present application, the piston rod of the pushing hydraulic cylinder passes through the fixed plate and is slidably connected to the fixed plate, and the pushing plate slides in the pushing groove through the pushing hydraulic cylinder.

[0013] Through the above technical solution, the push plate sliding in the push groove can push the ejected stamping parts, thereby pushing the stamped stamping parts out of the push groove, and cooperating with the unloading plate to realize the unloading work.

[0014] As a preferred technical solution of the present application, the negative pressure chip removal mechanism includes an absorption box, a sealing cover is provided on the upper side of the absorption box, a through hole is provided on the front side of the absorption box and the through hole is connected to the absorption box, a filter is inserted into the interior of the absorption box, an induced draft fan is fixedly installed at a position behind the filter in the interior of the absorption box, and an air outlet is provided on the rear side of the absorption box and the through hole is connected to the absorption box.

[0015] Through the above technical scheme, the exhaust air of the induced draft fan is used to generate negative pressure suction in the absorption box, thereby generating negative pressure suction on the absorption hood through the telescopic hose that penetrates the absorption box. When the absorption hood moves through the push plate, it can absorb the waste chips and dust on the push trough, thereby avoiding the accumulation of waste chips and dust to cause blockage of the push mechanism and stamping parts.

[0016] As a preferred technical solution of the present application, the rear end of the telescopic hose is connected to the interior of the absorption box through a through hole, the air outlet of the induced draft fan is oriented toward the air outlet holes, and the number of the air outlet holes is several.

[0017] Through the above technical solution, the exhaust air of the induced draft fan is discharged through the air outlet, so that negative pressure suction can be formed inside the absorption box, thereby absorbing the waste chips and dust on the push chute.

[0018] As a preferred technical solution of the present application, the absorption cover includes a cover shell, the lower side of the cover shell is recessed upward to form a cavity, the cross-section of the cavity is trapezoidal, a connecting pipe communicating with the cavity is provided at the upper end of the cover shell, and the front end of the telescopic hose is communicated with the cavity through the connecting pipe.

[0019] Through the above technical solution, the outlet of the cavity faces the push trough, and the connecting pipe is used to realize the interconnection between the telescopic hose and the cavity, so that the negative pressure suction force of the negative pressure chip removal mechanism can act on the absorption cover, and then absorb the waste chips and dust through the cavity.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the present application, a negative pressure chip removal mechanism is used to form a negative pressure suction force on the pushing plate of the pushing mechanism. When the pushing plate moves in the pushing trough to push the material, the absorption cover that moves with the pushing plate forms a negative pressure suction force by the negative pressure chip removal mechanism, and then absorbs the dust in the pushing trough and the waste chips attached to the stamping parts, thereby avoiding the blockage of the pushing plate by the waste chips and dust, and at the same time avoiding the blockage of the workpiece top material hole by the accumulated dust and waste chips, thereby ensuring that the pushing mechanism can realize pushing, facilitating the unloading of the automatic press, and solving the problem that the push plate and stamping parts of the existing automatic press are blocked by dust and waste chips during the unloading process, thereby resulting in the inability to unload the material.
