The uncoiling blanking die has great advantages in improving the utilization rate of materials, improving the surface quality of panels, improving efficiency and reducing labor intensity, etc., and has been favored by more and more automobile companies.

Most of the existing uncoiling blanking adopts the method of producing one piece of finished material at a time. This layout method is simple and convenient, but for some finished materials with irregular shapes, as shown in Figure 6, the sheet is trapezoidal. It has the following disadvantages:

1. The material utilization rate is low, and the sheet material cannot be well utilized during layout;

2. The production efficiency is low, only one piece of finished material can be produced at a time, and the advantages of uncoiling and blanking cannot be fully utilized;

3. For smaller sheet materials, the single-sheet discharge cannot meet the requirements of the step distance of the machine tool, resulting in the inability to perform uncoiling and blanking production.

Utility model content

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a discharge mechanism for the uncoiling blanking die, which realizes the discharge of two pieces at a time and expands the application range of the uncoiling blanking die.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a discharge mechanism for uncoiling and blanking molds, including a cylinder, a push plate, a support seat, and a cylinder slider. On the track, the bottom of the support seat is arranged on the cylinder slide block, and the top of the support seat is hinged with the push plate through a revolving pin.

One end of the push plate has a pointed structure, and the other end of the push plate has a square structure.

The weight of the square structural end of the push plate is greater than the weight of the pointed structural end of the push plate.

Compared with the prior art, the utility model has the following advantages:

1. Using this mechanism, two pieces of material can be discharged in one stamping process, which greatly improves the production efficiency;

2. Expand the application range of uncoiling and blanking. Through the two-piece discharge mechanism at a time, the two boards are matched with the discharge, and the size of the two boards can meet the step distance requirements;

3. Improve the utilization rate of materials. For sheets with irregular shapes, they can cooperate with other shapes to make layouts, so as to maximize the utilization of materials and reduce the production cost of enterprises;

4. The discharge mechanism is simple in structure and easy to use.

Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figure 1, through the discharge mechanism of the utility model combined with the uncoiling blanking mold, two sheets of sheet material can be dropped at one time. For sheets with irregular shapes, the sheets can be matched with each other to arrange the layout to maximize the improvement. Material utilization, reduce production costs of enterprises. As shown in the figure, the finished sheet Ⅰ1 and the finished sheet Ⅱ2 are arranged together, and the process gap is made at the position of the dotted line without affecting the drawing, and the discharge is coordinated with the discharge mechanism. This layout method can maximize the savings of the sheet material.

As shown in Figure 2, a discharge mechanism for an uncoiling blanking mold can simply and quickly push the finished material onto the conveyor belt during the working process of the uncoiling blanking line. The discharge mechanism includes a cylinder 3, a push plate 4, a support Seat 6, cylinder slide block 7, and cylinder slide block 7 is located on the track of cylinder 3, and the bottom of support base 6 is located on cylinder slide block 7, and support base 6 top is hinged with push plate 4 by repin 5; One end is a pointed structure, and the other end of the push plate is a square structure; the weight of the square structure end of the push plate is greater than the weight of the pointed structure end of the push plate. The discharge mechanism is arranged between the uncoiling blanking mold and the conveyor belt 8, and is used in conjunction with the roller frame.

As shown in Figures 3 to 5, the uncoiling and blanking mold is opened, and the entire mold and the components of the uncoiling and blanking discharge mechanism are in the initial state of reset. At this time, the pointed structure at the front end of the push plate 4 blocks the plate. The edge of the craft notch. When the mold and bed continue to move downward, the pressing core presses the plate, and the blanking knife block cuts the plate for blanking. After the blanking knife block cuts the plate, the finished plate I1 is transported away with the conveyor belt and passed through the material selection mechanism Stacking after selection; at the same time, the cylinder is opened, the cylinder slider 7 moves to the right, the support seat 6 and the push plate 4 fixed on the cylinder slider 7 also move to the right together, and the front end of the push plate blocks the finished sheet II 2 At the left end, the push plate pushes the finished sheet II onto the conveyor belt 8 driven by the cylinder slider and the support seat.

The finished sheet II is transported away with the conveyor belt and stacked after being selected by the material selection mechanism, thus completing the discharge and stacking of two finished sheets.

The cylinder slider moves reversely immediately after the stroke, and the cylinder slider drives the supporting seat and the push plate to move in reverse. During the movement, the front end of the push plate touches the oncoming plate, and the front end of the push plate is under the pressure of the plate. Rotate down around the swivel pin to give way to the plate.

The front end of the push plate performs a reset movement under the plate until it reaches the gap of the plate process. The front end of the push plate loses the pressure of the plate and naturally turns upwards around the rotary pin, and gets stuck on the edge of the plate process gap, reaching the initial state of reset. , waiting for the next stamping and discharging work, so that two pieces of finished materials can be discharged smoothly every time.

During the whole movement process, the gravity difference between the front end of the push plate and the rear end is utilized to allow the front end of the push plate to rotate around the rotary pin, thereby realizing the pushing and reset work of the push plate. Under normal conditions, the gravity of the rear end of the push plate is greater than that of the front end, and the front end is naturally upturned, and the pushing work is completed under the drive of the cylinder slider. When the push plate returns, the front end meets the plate, and part of the gravity of the plate presses on the front end of the push plate, causing the gravity on the front end to be greater than that on the rear end. Complete the reset work.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model.
