Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a forming device for mechanical parts. Background Art

[0002] Stamping forming is a forming processing method that uses a press and a die to apply external forces to plates, strips, tubes, profiles, etc., so that they undergo plastic deformation or separation, thereby obtaining mechanical parts with the required shapes and sizes. When assembling a machine, stamping forming operations are required. However, there are certain problems with existing devices during use and continuous improvement is still needed;

[0003] For example, a stamping forming device for sewing machine parts disclosed in the utility model with the authorization announcement number CN217831425U includes a production platform, a support frame, a lifting device, a stamping table, a buffer member, a high-efficiency hydraulic cylinder, a stamping die, and a positioning member. The support frame is arranged on the top of the production platform. The device operates the high-efficiency hydraulic cylinder to perform high-efficiency stamping on the stamping die. During stamping, the lifting plate drives the positioning column to move downward and can be inserted into the positioning cylinder. Thus, during stamping, the stamping die is not prone to problems such as twisting and offset, and the stamping effect is better. The buffer member can elastically support the stamping table, so that the parts are not easily damaged due to excessive pressure during stamping. The device achieves semi-automatic stamping ability, has a relatively high stamping forming efficiency, good stamping positioning effect, and a relatively high finished product rate of parts, reducing costs while improving production efficiency.

[0004] When the device works, first place the material to be stamped and formed on the stamping table, and then stamp the placed material to be stamped and formed. Since there is only one stamping table, after stamping is completed, it needs to be taken out manually, and then the next material to be stamped is placed on the stamping table to carry out the stamping work on the subsequent materials. As a result, this setting method has low working efficiency and poor continuity, affecting the working efficiency. At the same time, after the material is stamped and formed, it still needs to be manually picked up from the processing table at a close distance. If a device failure causes the stamping die to drop, it may cause work injury problems. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a forming device for mechanical parts, which can solve the technical problems that since there is only one stamping table, after stamping is completed, it needs to be taken out manually, and then the next material to be stamped is placed on the stamping table to carry out the stamping work on the subsequent materials. As a result, this setting method has low working efficiency and poor continuity, affecting the working efficiency. At the same time, after the material is stamped and formed, it still needs to be manually picked up from the processing table at a close distance. If a device failure causes the stamping die to drop, it may cause work injury problems.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions: A mechanical part forming device, including a production platform, on the upper surface of which two chutes are symmetrically provided. In both of the two chutes, a lead screw is rotationally connected with a limit. On the outer sides of both of the two lead screws, a slider is sleeved and connected with a thread. On the upper surfaces of the two sliders, a support frame is jointly connected. On the inner top wall of the support frame, two electric push rods are provided. At the free ends of the two electric push rods, a lifting plate is jointly connected. At the center position of the lower surface of the lifting plate, a high-efficiency hydraulic cylinder is connected. At the free end of the high-efficiency hydraulic cylinder, a stamping punch is connected. On the upper surface of the production platform and symmetrically arranged between the two chutes, two stamping platforms are provided. On the upper surfaces of the two stamping platforms, a stamping die is provided respectively.

[0007] As a preferred technical solution of the present utility model, one end of the lead screw passes through the side wall of the production platform movably and is connected with a servo motor for rotating and adjusting the lead screw.

[0008] As a preferred technical solution of the present utility model, at the four corners of the bottom wall of the lifting plate, a positioning column is fixedly connected respectively. At the four corners of the upper surface of the stamping platform, a positioning cylinder which is inserted and limited with the positioning column is fixedly connected respectively.

[0009] As a preferred technical solution of the present utility model, between the four corners of the bottom wall of the stamping platform and the upper surface of the production platform, a damping rod is connected. A buffer spring is sleeved on the outer side of the damping rod.

[0010] As a preferred technical solution of the present utility model, two semi-circular buffer rubber blocks are symmetrically arranged at the bottom wall of the stamping platform.

[0011] As a preferred technical solution of the present utility model, at the four corners of the bottom wall of the production platform, a universal wheel for facilitating the movement and adjustment of the whole device is connected respectively.

[0012] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0013] Through the cooperation of the lead screw and the slider, the movement adjustment of the support frame is realized. Through the movably adjusted support frame, the stamping punch on the support frame is driven to move back and forth above the two stamping platforms. When a stamping punch punches the material in the stamping die above one stamping platform, the punched mechanical part in the stamping die above the other stamping platform can be taken out or the material to be punched can be placed. The setting of this structure improves the continuity and working efficiency. At the same time, there is no need for manual close contact with the stamping platform to take out the punched mechanical part in the stamping die, thus avoiding the work injury risk brought by the sudden drop of the stamping punch due to equipment failure.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following combines specific embodiments to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] Please refer to Figures 1-4 As shown in the figure, the present utility model provides a mechanical part forming device. On the upper surface of the production platform 1, two slide grooves 2 are symmetrically opened. Then, lead screws 3 are rotationally connected in a limited manner in the two slide grooves 2, and one end of each lead screw 3 passes through the side wall of the production platform 1 movably and is connected to a servo motor. Through the setting of the servo motor, the rotation of the lead screw 3 can be adjusted. Then, slide blocks 4 are threadedly sleeved and connected to the outer sides of the two lead screws 3. Then, a support frame 5 is commonly connected to the upper surfaces of the two slide blocks 4. And two electric push rods 6 are arranged on the inner top wall of the support frame 5, and a lifting plate 7 is commonly connected to the free ends of the two electric push rods 6. Then, a high-efficiency hydraulic cylinder 9 is connected to the center position of the lower surface of the lifting plate 7, and a stamping punch 10 is connected to the free end of the high-efficiency hydraulic cylinder 9. At the same time, two stamping tables 12 are symmetrically arranged on the upper surface of the production platform 1 and between the two slide grooves 2. Then, a stamping die 11 is arranged on the upper surface of each of the two stamping tables 12;

[0022] During adjustment for use, first place the material to be stamped and formed in the stamping die 11 on the upper surface of a stamping table 12. Then, rotate the adjusting screw rod 3 through a servo motor. The threaded drive of the rotating adjusting screw rod 3 drives the slider 4 to drive the support frame 5 to move above the stamping die 11 where the material to be stamped and formed has been placed. Next, the stamping punch 10 provided on the inner top wall of the support frame 5 moves downward to stamp and form the material placed in the stamping die 11. At the same time, place the next material to be stamped and formed in another stamping die 11. Then, remove the support frame 5 from the machined parts that have been stamped and formed, and move it above the second stamping die 11 where the stamped and formed material has been placed for stamping. At the same time, remove the machined parts in the first stamping die 11 and place the next material to be stamped. Then repeat the above operations;

[0023] As a further implementation manner of this embodiment, as Figures 1-4 shown, at the four corners of the bottom wall of the lifting plate 7, a positioning column 8 is fixedly connected. Then, at the four corners of the upper surface of the stamping table 12, a positioning cylinder 13 that is in limit insertion fit with the positioning column 8 is fixedly connected. Through the limit insertion fit of the positioning column 8 and the positioning cylinder 13, it is avoided that the stamping punch 10 deflects during the downward stamping process, thereby affecting the quality of the machined parts formed by stamping. Then, between the four corners of the bottom wall of the stamping table 12 and the upper surface of the production platform 1, a damping rod 15 is connected and arranged. A buffer spring 14 is sleeved outside the damping rod 15. Two semi-circular buffer rubber blocks 16 are symmetrically arranged on the bottom wall of the stamping table 12. Through the cooperation of the buffer spring 14 and the damping rod 15, when the stamping table 12 moves downward, the damping rod 15 plays a role in limiting it, and the elastic force of the buffer spring 14 plays a certain supporting role, thereby avoiding damage to the machined parts during stamping. At the same time, the two buffer rubber blocks 16 can further improve the force buffering ability of the stamping table 12;

[0024] Specific working principle:

[0025] When stamping and forming mechanical parts, first place the material to be stamped and formed in the stamping female die 11 on the upper surface of a stamping table 12. Then, rotate the adjusting screw rod 3 through a servo motor. The threaded driving slider 4 driven by the rotated adjusting screw rod 3 drives the support frame 5 to move above the stamping female die 11 where the material to be stamped and formed has been placed. Next, two electric push rods 6 arranged on the inner top wall of the support frame 5 first drive the lifting plate 7 to move downward, so that the positioning column 8 is inserted into the positioning cylinder 13 to position the stamping male die 10. Then, drive the stamping male die 10 to move downward through the high-efficiency hydraulic cylinder 9 to stamp and form the material placed in the stamping female die 11. At the same time, place the next material to be stamped and formed in another stamping female die 11. Then, remove the support frame 5 from the mechanically formed parts that have been stamped, and move it above the second stamping female die 11 where the stamped and formed material has been placed for stamping. At the same time, take out the mechanically formed parts in the first stamping female die 11, and place the next material to be stamped. Then, repeat the above operations. The setting of this structure improves the continuity and working efficiency. At the same time, there is no need for manual close contact with the stamping table 12 to take out the mechanically formed parts that have been stamped in the stamping female die 11, thus avoiding the work injury risk caused by the sudden descent of the stamping male die 10 due to equipment failure.
