Description

Technical Field

[0001] The utility model relates to the technical field of discharging waste materials from a concave mold plate, in particular to a waste material discharging device for a blanking mold for a semi-finished number plate. Background Art

[0002] The finished license plate for automobiles is made from semi-finished license plates, which are made from blanking dies. Figure 1 As shown, it includes a workbench 1, a concave template 2 fixed in the workbench 1, and a blanking hole 3 opened in the concave template 2. The concave template 2 is provided with a discharging mechanism for discharging waste materials remaining on the top surface of the concave template 2, wherein the discharging mechanism includes a trough 4 opened on the top surface of the concave template 2 and located on the right side of the blanking hole 3, and the bottom of the trough 4 is fixed with an air outlet pipe 5 that penetrates downward through the bottom surface of the concave template 2, and the lower end of the air outlet pipe 5 is connected with a hose 6, and the other end of the hose 6 is connected to the working port of the air compressor, and the upper end of the air outlet pipe 5 is connected to the trough 4.

[0003] The method of forming a semi-finished license plate using the blanking die is:

[0004] S1. The worker places the blank plate flat on the top surface of the concave plate 2 of the blanking die, and ensures that the blank plate covers both the blanking hole 3 and the sink 4; controls the punch of the stamping die to move downward. When the punch cooperates with the blanking hole 3 of the concave plate 2, a semi-finished number plate can be formed on the basis of the blank plate. The semi-finished number plate falls to the ground through the blanking hole 3. At the same time, waste material 7 covering the sink 4 remains on the top surface of the concave plate 2, such as Figure 2 As shown;

[0005] S2, the operation steps for the worker to discharge the waste 7 from the concave plate 2 are as follows: the worker turns on the air compressor of the discharge mechanism, and the air compressor produces pressurized gas, which is finally ejected upward through the outlet pipe 5 and the top port of the outlet pipe 5. After the upward ejected pressurized gas enters the sink 4, the pressurized gas pushes the waste 7 upward. Under the action of the air pressure, the waste 7 is blown onto the workbench 1, thereby realizing the discharge of the waste 7 from the concave plate 2;

[0006] S3. The worker repeats the operations of steps S1 to S2 to continuously produce a plurality of semi-finished number plates, and continuously discharges the waste remaining on the top surface of the concave plate 2.

[0007] However, although the discharge mechanism of this blanking die can discharge the waste material 7 remaining on the top surface of the concave die plate 2, it still has the following technical defects:

[0008] I. Sometimes the waste 7 is tightly attached to the top surface of the concave template 2, so that the pressurized gas discharged from the air outlet pipe 5 cannot blow the waste 7 upward, resulting in that the waste 7 can only be removed from the top surface of the concave template 2 manually, thereby increasing the work intensity of the workers in removing the waste 7.

[0009] II. The direction in which the waste 7 is blown out by the pressurized gas is uncertain, causing the waste 7 to be scattered all over the workbench 1 , resulting in the need to manually collect all the waste 7 scattered on the workbench 1 , which undoubtedly increases the work intensity of the workers in collecting the waste 7 .

[0010] Therefore, there is an urgent need for a waste discharging device that can reduce the workload of workers in discharging waste and reducing the workload of workers in collecting waste. Utility Model Content

[0011] The utility model aims to overcome the shortcomings of the prior art and provide a waste material discharging device for a semi-finished number plate blanking die, which can reduce the work intensity of workers in discharging waste materials and collecting waste materials.

[0014] A bracket located in the sink is welded on the outer cylindrical surface of the upper end of the vacuum tube, and a nozzle arranged upward and tilted to the right is welded on the left end of the bracket. An air outlet pipe is connected to the bottom port of the nozzle. The air outlet pipe passes downward through the bottom surface of the concave template and is connected to a hose at the extended end. The other end of the hose is connected to the working port of the air compressor.

[0015] Rods are fixedly arranged on the bottom surface of the lifting plate and on the left and right sides of the guide column, and the two rods penetrate the connecting plate downward.

[0016] The bottom of the sink is provided with a through hole penetrating downwardly through the bottom surface of the concave template, and the air outlet pipe is slidably installed in the through hole.

[0033] The utility model is further described below in conjunction with the accompanying drawings, and the protection scope of the utility model is not limited to the following:

[0034] like Figure 3~Figure 6 As shown, a waste discharging device for a semi-finished license plate blanking die comprises a sink 4 provided on the top surface of a concave plate 2 of the blanking die, a vertical plate 8 fixedly arranged on the bottom surface of a workbench 1 of the blanking die and located on the right side of the sink 4, a connecting plate 9 and a self-locking motor 10 fixedly arranged on the left end surface of the vertical plate 8, a lifting plate 11 supported on the top surface of the connecting plate 9, a guide column 12 penetrating downwardly through the connecting plate 9 fixedly arranged on the bottom surface of the lifting plate 11, a rack 13 connected to the bottom of the guide column 12, an output shaft of the self-locking motor 10 arranged forward, and a gear 14 mounted on the output shaft, the gear 14 meshing with the rack 13; a collecting basket 21 for collecting waste material located on the right side of the concave plate 2 is placed on the surface of the workbench 1.

[0035] A vacuum pump 15 is fixedly provided on the top surface of the lifting plate 11, and a vacuum tube 16 is connected to the working port of the vacuum pump 15, which penetrates upward through the bottom surface of the concave template 2 and extends into the sink 4. A suction head 17 is fixedly provided at the top port of the vacuum tube 16, and the top surface of the suction head 17 is flush with the top surface of the concave template 2, and the suction head 17 is made of silicone. Rods 20 are fixedly provided on the bottom surface of the lifting plate 11 and on the left and right sides of the guide column 12, and the two rods 20 both penetrate downward through the connecting plate 9.

[0036] A bracket 18 located in the sink 4 is welded on the outer cylindrical surface of the upper end of the vacuum tube 16, and a nozzle 19 tilted upward and set to the right is welded on the left end of the bracket 18. The bottom end of the nozzle 19 is connected to an air outlet pipe 5, which passes through the bottom surface of the concave template 2 downward, and is connected to a hose 6 at the extended end, and the other end of the hose 6 is connected to the working port of the air compressor. A through hole is opened at the bottom of the sink 4, which passes through the bottom surface of the concave template 2 downward, and the air outlet pipe 5 is slidably installed in the through hole.

[0037] The waste discharging device also includes a controller, which is electrically connected to the air compressor, the self-locking motor 10, and the vacuum pump 15 via a signal line. Workers can control the start or stop of the air compressor, the self-locking motor 10, and the vacuum pump 15 through the controller, which facilitates the workers' operation and has the characteristics of a high degree of automation.

[0038] The method of forming a semi-finished license plate with a blanking die is:

[0039] The worker places the blank plate flat on the top surface of the concave plate 2 of the blanking die, and ensures that the blank plate covers both the blanking hole 3 and the sink 4; controls the punch of the stamping die to move downward, and when the punch cooperates with the blanking hole 3 of the concave plate 2, a semi-finished number plate can be formed on the basis of the blank plate, and the semi-finished number plate falls to the ground through the blanking hole 3. At the same time, waste material 7 covering the sink 4 remains on the top surface of the concave plate 2, as shown in FIG. Figure 7 As shown;

[0040] The method of discharging the residual waste 7 on the top surface of the concave plate 2 is:

[0041] S1, the worker starts the vacuum pump 15, and the vacuum pump 15 evacuates the inner cavity of the vacuum tube 16 and the suction head 17. Under the negative pressure, the waste material 7 is just adsorbed and fixed on the suction head 17;

[0042] S2, control the self-locking motor 10 to start, the self-locking motor 10 drives the gear 14 to rotate, the gear 14 drives the rack 13 to move upward, the rack 13 drives the guide column 12 to move upward, the guide column 12 drives the lifting plate 11 to move upward synchronously, the lifting plate 11 drives the vacuum pump 15 to move upward synchronously, the vacuum pump 15 drives the vacuum tube 16 to move upward synchronously, the vacuum tube 16 drives the bracket 18 and the suction head 17 to move upward synchronously, wherein the bracket 18 drives the nozzle 19 to move upward, the nozzle 19 drives the air outlet pipe 5 to move upward synchronously, and at the same time, the suction head 17 drives the adsorbed waste 7 to move upward synchronously, so that the waste 7 attached to the top surface of the concave template 2 is separated from the concave template 2, such as Figure 8 As shown;

[0043] S3. When the waste 7 moves to the set height, the controller controls the self-locking motor 10 to close, and the waste 7 remains motionless at this time; then the controller controls the air compressor to start, and the air compressor produces pressurized gas, which passes through the hose 6, the air outlet pipe 5, the nozzle 19 in sequence, and is finally blown out from the top port of the nozzle 19, and the blown pressurized gas acts on the bottom surface of the waste 7; then the controller controls the vacuum pump 15 to close, and the suction head 17 no longer absorbs the waste 7. At this time, the waste 7 is blown to the right into the collection basket 21 by the pressurized gas, as shown in FIG. Fig. 9 As shown, the waste material 7 is finally discharged from the concave plate 2;

[0044] S4, after the waste 7 is discharged, the self-locking motor 10 is controlled to reverse, the self-locking motor 10 drives the gear 14 to reverse, the gear 14 drives the rack 13 to move downward, the rack 13 drives the guide column 12, the lifting plate 11 and the vacuum pump 15 to move downward, thereby resetting the suction head 17 and the nozzle 19;

[0045] S5 , by repeating the operations of steps S1 to S4 , the waste materials 7 remaining on the concave plate 2 can be continuously discharged into the collection basket 21 .

[0046] Among them, it can be seen from steps S2 to S4 that the present discharging device only needs to control the vacuum pump 15 to start first, so that the suction head 17 adsorbs and fixes the waste 7; then control the self-locking motor 10 to start, so that the suction head 17 moves upward, thereby separating the waste 7 from the concave plate 2; then control the air compressor to start, so that the pressure gas blown out by the nozzle 19 acts on the bottom surface of the waste 7; finally, control the vacuum pump 15 to close, and the suction head 17 no longer adsorbs the waste 7. At this time, the waste 7 is blown into the collection basket 21 by the pressure gas. It can be seen that compared with the present discharging device, Figure 1 The discharging mechanism can make all the discharged waste 7 enter the collecting basket 21, thereby effectively avoiding the waste 7 from being scattered all over the workbench 1. Therefore, workers do not need to manually collect the waste 7 later, which greatly reduces the work intensity of workers in collecting waste.

[0047] In addition, since the suction head 17 first sucks the waste 7 and then pushes the waste 7 upward, it effectively overcomes the technical problem that the waste 7 can only be removed from the concave template 2 manually because the waste 7 is tightly adsorbed on the top surface of the concave template 2. The discharging device realizes automatic discharge of the waste 7, thereby greatly reducing the work intensity of workers in discharging the waste.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
