Description

A punch automatic unloading device

technical field

The utility model relates to a punch unloading device, in particular to an automatic unloading device which can automatically discharge the blank under the blanking opening of the punch.

Background technique

Generally, punching workpieces by punching machines have a significant production feature, that is, high production efficiency, that is, the punching frequency of the punching machine is high, and there are many workpieces punched in a unit time, while the blanking and discharging device of the traditional punching machine mainly adopts drawer type or Use gravity to make the blanking slide out directly from the blanking chute. For the drawer type device, it needs manual operation to take out the blanking. This operation method greatly affects the production efficiency, and the manual labor intensity is high. It will also cause certain dangers to the operator; if gravity is used to make the blanking slide out of the blanking chute directly, affected by the sliding angle of the waste, often the blanking will be stuck in the blanking chute and cannot be slid out, resulting in falling. The chute is blocked, which will affect the production efficiency, and at the same time, there is a certain danger to the operator. For example, Chinese Patent Publication No. CN1363457, published on August 14, 2002, the name of the invention is electromagnetic punching machine, and the application discloses an electromagnetic punching machine, comprising: frame and working platform, characterized in that: A punch spindle covered with an iron bush is provided, and a high-power magnetic coil is provided corresponding to the iron bush section of the punch spindle. In principle, this application simplifies the transmission mechanism of the punch press, which has a certain energy-saving effect. However, the blanking and discharging device of the electromagnetic punch press has not been improved. According to the drawer type of the traditional punch press or the use of gravity to make the blanking directly Sliding out from the blanking chute also has the problem that the blanking and discharging device in the traditional punching machine will affect the production efficiency, the manual labor intensity is high, and there is also a certain degree of danger for the operator.

Utility model content

The purpose of this utility model is to overcome the problem that the blanking and discharging device in the traditional punching machine will affect the production efficiency, its manual labor intensity is high and there is a certain danger to the operator, and to provide a device that can automatically discharge the blanking of the punching machine Automatic unloading device.

The technical scheme of the utility model is:

An automatic unloading device for a punch press, which includes a controller and a discharge hopper arranged below the discharge port of the punch press. A pneumatic lifting device that can lift the rear end of the discharge hopper is provided between the body, and the controller is connected to the pneumatic lifting device. In this scheme, the front end of the unloading hopper is reversibly set on the punch machine body, and at the same time, a pneumatic lifting device that can lift the rear end of the unloading hopper is installed between the rear end of the unloading hopper and the punch machine body. When the force drives the punching die to start working, the controller will automatically control the pneumatic lifting device to lift the rear end of the unloading hopper, which can be turned around the front mouth of the unloading hopper, so that the bottom surface of the unloading hopper becomes a downward slope, thereby lifting the unloading hopper The blanking discharge in the punching machine, the above-mentioned punching die is the process equipment installed on the press for the production of punching parts, which is composed of upper and lower parts that cooperate with each other; if in the process of discharging blanking, some blanking in the discharge hopper Because the card is not discharged in the discharge hopper, the operator presses the quick lifting button, and the controller controls the pneumatic lifting device to make the discharge hopper quickly rotate up and down around the front mouth of the discharge hopper. Under the action of inertia, the stuck in the discharge hopper The falling material inside shakes loose and is discharged down the discharge hopper. This scheme automatically controls the pneumatic lifting device through the controller, which can automatically discharge the blanking material in the unloading hopper. It does not need to take out the blanking material through manual operation, which can improve production efficiency and reduce manual labor intensity. Due to the use of automatic control It will not cause harm to the operator.

Preferably, the pneumatic lifting device includes a cylinder vertically arranged on the press body and guide rails respectively arranged on the left and right sides of the outer bottom surface of the discharge hopper, and the end of the piston rod of the cylinder is provided with a A link that slides between the rails. The controller controls the expansion and contraction of the cylinder, thereby driving the piston rod in the cylinder to do up and down telescopic movement. When the cylinder is pushed up, the connecting rod at the end of the piston rod slides upward along the guide rails on the left and right sides of the discharge hopper, driving the discharge hopper around the discharge hopper The mouth of the front end of the bucket rotates upwards to discharge the blanks in the discharge hopper; when the cylinder shrinks and moves downward, the connecting rod at the end of the piston rod slides down along the guide rails on the left and right sides of the discharge hopper, driving the discharge hopper around the front end of the discharge hopper The mouth of the bucket turns downward. In this scheme, a cylinder is used as a pneumatic lifting device, which has a simple structure, high reliability, and is easy to realize production. The above-mentioned pneumatic lifting device as a preferred solution can also be replaced by the following solution, the pneumatic lifting device includes a cylinder arranged below the discharge hopper, the bottom of the cylinder is rotatably arranged on the punch body, and the end of the piston rod in the cylinder can be The rotating one is connected with the rear end of the unloading hopper. In this scheme, the bottom of the cylinder is rotatably arranged on the punch machine body, and the end of the piston rod in the cylinder is rotatably connected with the rear end of the discharge hopper. When the cylinder is pushed up, the piston rod drives the discharge hopper around the front end of the discharge hopper. The mouth of the bucket rotates upwards to discharge the blanks in the discharge hopper; when the cylinder shrinks and moves downward, the piston rod drives the discharge bucket to rotate downward around the mouth of the front end of the discharge hopper.

Preferably, a C-shaped chute is provided on the guide rail, and rollers cooperating with the C-shaped chute are provided at both ends of the connecting rod at the end of the piston rod. When the cylinder moves up or down, the connecting rod at the end of the piston rod will slide up and down along the guide rails set on the left and right sides of the discharge hopper, and rollers are set at both ends of the connecting rod to cooperate with the chute set on the guide rail, which can reduce the up and down sliding At the same time, the chute is set in a C shape, so that the rollers can be stuck in the chute and are not easy to loosen and fall out.

Preferably, the bottom surface of the discharge hopper is set as an inclined bottom surface. The bottom surface of the unloading hopper is set as an inclined plane inclined to the opening of the unloading hopper, that is, the opening of the unloading hopper is located at the lower end of the inclined bottom surface, which can be more conducive to the discharge of the blanking in the unloading hopper.

The beneficial effect of the utility model is: the blanking in the unloading hopper can be automatically discharged without manual operation to take out the blanking, which can improve production efficiency and reduce labor intensity, and will not cause harm to operators at the same time .
