Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of blanking devices, and particularly relates to a laser tailor-welded blanking device. Background Art
[0002] Laser tailor-welding uses a laser beam with a high energy density as a heat source. The laser beam is focused on the splicing part of the material to be welded, causing the material to quickly melt and fuse together. After cooling, a strong welded joint is formed. The energy of the laser is highly concentrated, and the heating and cooling processes of the welding area can be precisely controlled. After welding, circular workpieces are usually blanked by means of a blanking track and a push plate, and the circular workpieces are blanked onto a conveyor belt or other transportation components for the next operation or for receiving materials.
[0003] However, the existing blanking devices have problems. For example, when blanking, a round bar is pushed to a baffle. Since the width of the blanking track is generally greater than the length of the round bar (to facilitate the blanking of the round bar), it is necessary to correct the position when reaching the baffle. One end of the round bar is abutted against the side wall of the guiding track, and then blanking is carried out. In the prior art, auxiliary devices such as air cylinders are generally required. A guiding plate is installed on the output shaft of the air cylinder, etc. Such a structure is relatively complex. Therefore, we propose a new laser tailor-welded blanking device to solve the above problems. Content of the Utility Model

A push plate is arranged at the rear side of the workpiece, and the push plate drives the workpiece to move along the guide rail.
[0007] First baffle and second baffle are respectively and fixedly installed on both sides of the substrate. A guiding member is also slidably arranged outside the push plate. A contact column is fixedly arranged at one end of the guiding member away from the workpiece. A protruding portion is fixedly arranged on one side of the second baffle close to the contact column. When the push plate moves, the contact column is extruded by the protruding portion, and the guiding member presses the workpiece against the first baffle, so that the workpiece is aligned.
[0008] Furthermore, the guide rail includes guide rail base columns uniformly arranged on the upper end surface of the substrate. A guide rail main body is fixedly arranged at the upper end of the guide rail base columns. The guide rail main body is a cylinder, and the workpiece moves linearly along the guide rail main body.
[0009] Furthermore, a driving air cylinder is also arranged on the substrate. An output shaft is telescopically arranged at the front end of the driving air cylinder. The output shaft is fixedly connected with the push plate and is used to drive the push plate to move linearly.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0026] Embodiment: As Figures 1-4 shown, a laser welded blanking device includes a substrate 10. A guide rail is provided on the upper end surface of the substrate 10. A workpiece 30 is also provided on the guide rail. A push plate 22 is provided at the rear side of the workpiece 30. The push plate 22 drives the workpiece 30 to move along the guide rail;
[0027] First baffles 13 and second baffles 16 are respectively and fixedly installed on both sides of the substrate 10. An alignment part 23 is slidably provided outside the push plate 22. A contact column 231 is fixedly provided at one end of the alignment part 23 away from the workpiece 30. A protrusion 161 is fixedly provided on one side of the second baffle 16 close to the contact column 231. When the push plate 22 moves, the contact column 231 is squeezed by the protrusion 161, and the alignment part 23 presses the workpiece 30 against the first baffle 13, so that the workpiece 30 is aligned;
[0028] Further, as Figure 1 shown, the guide rail includes guide rail base columns 11 uniformly arranged and fixed on the upper end surface of the substrate 10. A guide rail main body 12 is fixedly provided at the upper end of the guide rail base columns 11. The guide rail main body 12 is a cylinder, and the surface of the cylinder is smooth, so that the workpiece 30 can move linearly along the guide rail main body 12. A driving cylinder 20 matching the push plate 22 is also provided on the substrate 10. An output shaft 21 is telescopically provided at the front end of the driving cylinder 20. A fixed connection is provided between the output shaft 21 and the push plate 22 for driving the push plate 22 to move linearly;
[0029] Further, as Figure 4As shown, a groove 221 is also formed on the contact surface between the push plate 22 and the workpiece 30. The workpiece 30 is fitted in the groove 221. By starting the driving cylinder 20, the output shaft 21 of the driving cylinder 20 drives the push plate 22 to move forward, and the push plate 22 can push the workpiece 30 along the guide rail main body 12;
[0030] Furthermore, as Figures 3-4 shown, a fillet 232 is formed at one end of the contact post 231 close to the convex portion 161, and the convex portion 161 is also a fillet structure; this facilitates the movement of the contact post 231 along the fillet structure of the convex portion 161 and prevents the contact post 231 from being stuck;
[0031] Furthermore, as Figure 1 shown, a partition cylinder 15 is also provided at the gap of the guide rail base column 11 (i.e., between two groups of guide rail base columns 11). The partition cylinder 15 is fixedly installed on the upper end surface of the base plate 10, and a partition post 151 is telescopically provided at the upper end of the partition cylinder 15. The workpiece 30 is pushed by the push plate 22 to the position of the partition post 151. At this time, the partition post 151 extends out to prevent the workpiece 30 from continuing to move. During this process, the contact post 231 passes through the convex portion 161, and the contact post 231 is squeezed by the convex portion 161. The contact post 231 and the alignment member 23 are integrally provided. Therefore, the alignment member 23 is pushed to squeeze the workpiece 30, so that the workpiece 30 is squeezed onto the first baffle 13, thus completing the alignment work. At this time, the partition post 151 is retracted, and the push plate 22 continues to push the workpiece 30 forward. Among them, a transition plate 14 is fixedly provided at the upper front part of the guide rail base column 11. The workpiece 30 passes through the transition plate 14 and is output to the transfer device for loading and unloading. The highest point of the guide rail main body 12 needs to be higher than the upper end surface of the transition plate 14 to prevent hindering the unloading of the workpiece 30;
[0032] Furthermore, as Figure 3 shown, a fixing block 24 is fixedly installed on the outside of the push plate 22, and a spring 25 is provided between the fixing block 24 and the alignment member 23. When the contact post 231 is not squeezed by the convex portion 161, the spring 25 can push the alignment member 23 outwards to leave a certain gap, facilitating the contact between the push plate 22 and the workpiece 30.
[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
