[0031] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the scope of protection of the present utility model.

[0032] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the present utility model provides a rapid prototyping stamping machine for plates, comprising:

[0033] A hollow seat 1, on which a plate stamping and forming mechanism is provided. It should be noted that the plate is subjected to stamping and forming treatment through the plate stamping and forming mechanism;

[0034] The plate stamping and forming mechanism includes a stamping component and an ejecting and blanking component. It should be noted that the plate is subjected to stamping and forming treatment through the stamping component, and the stamped and formed plate is subjected to ejecting and blanking treatment through the ejecting and blanking component;

[0035] The stamping component includes a plate stamping lower die 2, and a die groove 3 is formed at the top of the plate stamping lower die 2;

[0036] Through the above stamping component, the plate can be stamped and formed in the die groove 3;

[0037] The ejecting and blanking component includes a weight ejecting plate 8, a trapezoidal block 1 9, a hydraulic cylinder 2 10, a connecting piece 11, a guide plate 12, a trapezoidal block 2 13, an ejecting part 14, a blanking inclined plate 15 and a traction block 16. The top and bottom of the traction block 16 are respectively fixedly connected to the weight ejecting plate 8 and the trapezoidal block 1 9. It should be noted that subsequently, the weight ejecting plate 8 automatically moves downward by its own gravity;

[0038] The hydraulic cylinder 2 10 is fixedly installed on the side of the hollow seat 1, the hydraulic rod of the hydraulic cylinder 2 10 is fixedly connected to the connecting piece 11, the connecting piece 11 is fixedly connected to the ejecting part 14, the guide plate 12 is fixedly installed between the connecting piece 11 and the trapezoidal block 2 13, and the blanking inclined plate 15 is fixedly installed on the hollow seat 1 and the plate stamping lower die 2.

[0039] Through the above-mentioned ejection and blanking assembly, after the sheet is stamped and formed, the second hydraulic cylinder 10 is started. The second hydraulic cylinder 10 drives the connecting piece 11 to move to the right. The connecting piece 11 drives the trapezoidal block two 13 to move through the guide plate 12. The trapezoidal block two 13 first contacts the inclined surface of the trapezoidal block one 9. When it continues to move later, it will push the trapezoidal block one 9 through the inclined surface and lift the trapezoidal block one 9. Thus, the traction block 16 can drive the weight ejection plate 8 upwards, and the weight ejection plate 8 ejects the formed sheet. During this process, the connecting piece 11 slowly drives the ejector 14 towards the die groove 3. Then, the ejector 14 will push the sheet on the weight ejection plate 8 and eject the formed sheet to the blanking inclined plate 15. In this way, the formed sheet can be automatically ejected and blanked, reducing the labor intensity of the staff.

[0040] Specifically, the stamping assembly further includes a frame body 4, a first hydraulic cylinder 5, a plate member 6 and an upper die for sheet stamping 7. The frame body 4 is fixedly installed on the top of the hollow seat 1. The first hydraulic cylinder 5 is fixedly installed on the top of the frame body 4. The hydraulic rod of the first hydraulic cylinder 5 is fixedly connected to the plate member 6. The upper die for sheet stamping 7 is fixedly installed at the bottom of the plate member 6.

[0041] With the above structure, when the first hydraulic cylinder 5 is started, the first hydraulic cylinder 5 drives the plate member 6 to move. The plate member 6 drives the upper die for sheet stamping 7 to move. The upper die for sheet stamping 7 cooperates with the lower die for sheet stamping 2 to stamp and form the sheet.

[0042] Working principle:

[0043] S1: After the sheet is stamped and formed, the first hydraulic cylinder 5 is started, so that the plate member 6 drives the upper die for sheet stamping 7 to move upwards.

[0044] S2: The second hydraulic cylinder 10 is started. The second hydraulic cylinder 10 drives the connecting piece 11 to move to the right. The connecting piece 11 drives the trapezoidal block two 13 to move through the guide plate 12. The trapezoidal block two 13 first contacts the inclined surface of the trapezoidal block one 9. When it continues to move later, it will push the trapezoidal block one 9 through the inclined surface and lift the trapezoidal block one 9. Thus, the traction block 16 can drive the weight ejection plate 8 upwards, and the weight ejection plate 8 ejects the formed sheet. When the top of the trapezoidal block two 13 contacts the bottom of the trapezoidal block one 9, at this time, the top of the trapezoidal block one 9 contacts the inner wall of the top of the hollow seat 1, and the top of the weight ejection plate 8 is on the same horizontal line as the top of the lower die for sheet stamping 2.

[0045] S3: During this process, the connecting piece 11 slowly drives the ejector 14 towards the die groove 3. Then, the ejector 14 will push the sheet on the weight ejection plate 8 and eject the formed sheet to the blanking inclined plate 15. In this way, the formed sheet can be automatically ejected and blanked, reducing the labor intensity of the staff.

[0046] Specifically, an adaptation groove is formed on the inner wall of the bottom of the die groove 3, and the weight ejection plate 8 is located in the adaptation groove. It should be noted that the weight ejection plate 8 is stored.

[0047] Specifically, the traction block 16 is vertically slidably installed on the hollow seat 1 and the sheet metal stamping lower die 2, and the connecting member 11 is horizontally slidably installed on the hollow seat 1. It should be noted that it is convenient for the traction block 16 to move vertically and the connecting member 11 to move horizontally.

[0048] Specifically, the trapezoidal block two 13 is located on one side of the trapezoidal block one 9. It should be noted that when the trapezoidal block two 13 moves towards the trapezoidal block one 9, the trapezoidal block one 9 is pushed by the inclined surface.

[0049] Specifically, the bottom of the ejector 14 is on the same horizontal line as the top of the sheet metal stamping lower die 2. It should be noted that it is convenient to eject and unload the ejected sheet metal.

[0050] Specifically, a maintenance door is installed at the rear side of the hollow seat 1. It should be noted that the inside of the hollow seat 1 is maintained.

[0051] The above has introduced in detail a sheet metal rapid prototyping stamping machine provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model.
