Description

Technical Field

[0001] This utility model belongs to the field of machinery, and in particular relates to a stamping mechanism for metal sheets. Background Technology

[0002] A stamping mechanism is a special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). It is called a cold stamping die (commonly known as a cold stamping mold). Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Chinese utility model patent application number CN2019218114715 discloses a metal sheet stamping device for a television back panel. This device adjusts the distance between clamping blocks A and B by adjusting the position of a connecting rod, allowing the clamping mechanism to be used with molds of different sizes. Furthermore, the clamping mechanism can simultaneously fix multiple molds. Existing metal sheet stamping equipment requires manual adjustment of the positioning mechanism, which is cumbersome, and manual fixing cannot accurately move the metal sheet directly under the stamping mechanism, resulting in poor applicability. Utility Model Content

[0004] In view of this, the present invention aims to overcome the defects in the prior art and propose a stamping mechanism for metal sheets.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A stamping mechanism for metal sheets includes a lower stamping seat and an upper stamping seat. A support frame is provided on the lower stamping seat. A lifting cylinder passes through the support frame and is connected to the upper stamping seat. A lifting groove is provided in the upper stamping seat. A forming seat is provided in the lifting groove. A stamping unit is provided on the lower stamping seat. The stamping unit cooperates with the forming seat.

[0007] The stamping unit includes two identical stamping assemblies arranged opposite each other. Each stamping assembly includes an upper forming part, a guide rod, a guide spring, and a fixing member. Stamping frames are provided on both sides of the lower stamping seat. One end of the guide rod is connected to the upper forming part, and the other end passes through the stamping frame and is connected to the fixing member. The guide spring is sleeved on the outside of the guide rod and is located between the stamping frame and the fixing member.

[0008] Furthermore, the upper molded part has a guide slope at one end connected to the guide rod, and a sample groove on the upper surface and an upper stamping groove on the lower surface at the other end. The sample groove is used to accommodate the metal sheet.

[0009] Furthermore, the lower stamping seat is provided with two guide grooves, which are located below the upper forming part.

[0010] Furthermore, a lower stamping groove is provided at the middle position of the lower stamping seat. The shape of the lower stamping groove corresponds to that of the upper stamping groove and the lower formed part, and is used for stamping.

[0011] Furthermore, lifting holes are provided on both sides of the lifting groove; stamping parts are provided at the bottom of both ends of the upper stamping seat, and upper and lower stamping slopes are provided on the inner side of the stamping parts. The upper stamping slope is located above the lower stamping slope, and the slope of the upper stamping slope corresponds to the slope of the guide slope, while the slope of the lower stamping slope corresponds to the slope of the guide groove. The slope of the lower stamping slope is greater than the slope of the upper stamping slope.

[0012] The stamped part and the forming seat continue to descend. The lower stamping slope first enters the guide slope (the upper forming part is stationary at this time). At this time, the lower forming part enters the lower stamping groove to perform bottom stamping on the metal sheet. Then the stamped part continues to descend, and the lower stamping slope enters the guide groove. As the upper stamping slope continues to descend and the slope matches the guide slope, it drives the upper forming part to move inward (the stamping spring plays a reset role after stamping is completed), thereby realizing the stamping of the upper part of the metal sheet.

[0013] Furthermore, the forming base is provided with a lifting rod, which is connected to the lifting hole. The lower part of the forming base is provided with a lower forming part, which cooperates with the lower stamping groove and the upper stamping groove.

[0014] Furthermore, a lifting spring is provided inside the lifting groove, and the lifting spring is located between the upper stamping seat and the forming seat. During the stamping process of the forming seat, the forming seat continuously descends, and the lifting spring plays a buffering role.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The stamping mechanism for metal sheets described in this utility model drives the upper and lower forming parts to cooperate in stamping and forming by the cooperation of the stamping part and the upper forming part, thereby improving the stamping efficiency. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-4As shown, a stamping mechanism for metal sheets includes a lower stamping seat 1 and an upper stamping seat 4. A support frame 2 is provided on the lower stamping seat 1. A lifting cylinder 3 passes through the support frame 2 and is connected to the upper stamping seat 4. A lifting groove 43 is provided in the upper stamping seat 4. A forming seat 5 is provided in the lifting groove 43. A stamping unit 6 is provided on the lower stamping seat 1. The stamping unit 6 cooperates with the forming seat 5. The stamping unit 6 includes two stamping components with the same structure, which are arranged opposite to each other. The stamping component includes an upper forming part 61, a guide rod 62, a guide spring 63, and a fixing member 64. Stamping frames 11 are provided on both sides of the lower stamping seat 1. One end of the guide rod 62 is connected to the upper forming part 61, and the other end passes through the stamping frame 11 and is connected to the fixing member 64. The guide spring 63 is sleeved on the outside of the guide rod 62 and is located between the stamping frame 11 and the fixing member 64.

[0032] The upper forming part 61 has a guide slope 66 at one end connected to the guide rod 62, and a sample groove 67 on the upper surface and an upper stamping groove 65 on the lower surface at the other end. The sample groove 67 is used to accommodate a metal sheet. The lower stamping base 1 has two guide grooves 13 located below the upper forming part 61. A lower stamping groove 12 is located in the middle of the lower stamping base 1. The lower stamping groove 12 corresponds in shape to the upper stamping groove 65 and the lower forming part 52, and is used for stamping.

[0033] Lifting holes 42 are provided on both sides of the lifting groove 43; stamping parts 41 are provided at the bottom of both ends of the upper stamping seat 4, and upper stamping slope 411 and lower stamping slope 412 are provided on the inner side of the stamping parts 41. The upper stamping slope 411 is located above the lower stamping slope 412. The slope of the upper stamping slope 411 corresponds to the slope of the guide slope 66, and the slope of the lower stamping slope 412 corresponds to the slope of the guide groove 13. The slope of the lower stamping slope 412 is greater than the slope of the upper stamping slope 411.

[0034] The forming seat 5 is equipped with a lifting rod 51, which is connected to the lifting hole 42. A lower forming part 52 is provided at the lower part of the forming seat 5, and the lower forming part 52 cooperates with the lower stamping groove 12 and the upper stamping groove 65. A lifting spring 7 is provided inside the lifting groove 43, located between the upper stamping seat 4 and the forming seat 5. During the stamping process of the forming seat 5, as it continuously descends, the lifting spring 7 acts as a buffer.

[0035] Implementation process:

[0036] First, place the metal sheet in the sample slot 67. After it is accommodated, activate the lifting cylinder 3. The lifting cylinder 3 drives the upper stamping seat 4 and the forming seat 5 to descend. The lower stamping slope 412 first enters the guide slope 66 (the upper forming part 61 is stationary at this time, and the lifting rod 51 is located at the lower end of the lifting hole 42). At this time, the lower forming part 52 enters the lower stamping groove 12 to perform bottom stamping on the metal sheet. Then, the stamping part 41 continues to descend, and the lower stamping slope 412 enters the guide groove 13. Since the upper stamping slope 411 continues to descend (the forming seat 5 is stationary at this time, and the lifting cylinder 3 drives the upper stamping seat 4 and the forming seat 5 to descend), the lower stamping slope 412 enters the guide groove 13. The lowering rod 51 gradually moves to the upper end of the lifting hole 42, and the lifting spring 7 is compressed. The slope matches the guide slope 66, driving the upper forming part 61 to move inward (the stamping spring is compressed at this time). The upper stamping groove 65 stamps the upper part of the metal sheet. After the stamping is completed, the lifting cylinder 3 first drives the upper stamping seat 4 to move upward (at this time, the forming seat 5 is still in a stationary state, the stamping spring gradually relaxes, and the lifting rod 51 gradually moves to the lower part of the lifting hole 42). After the stamping spring is reset, it synchronously drives the forming seat 5 to move upward.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
