DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 2-3 As shown, the utility model provides a combined rib bending die, including: a lower die 4, a workpiece installed above the lower die 4, and a liftable upper die 3. The top of the lower die 4 is provided with a placement groove 7 and a stamping groove 8 from top to bottom. The placement groove 7 is used to laterally limit the workpiece above the stamping groove 8, and the stamping groove 8 is used to accommodate a storage space for stamping deformation.

[0023] As mentioned above, when using the lower mold 4 and the upper mold 3 provided by the utility model, the groove 7 is placed on the lower mold 4 to limit the workpiece, so as to prevent the workpiece from jumping out during stamping. At the same time, it is convenient to place the stamping section of the workpiece above the stamping groove 8, so that the stamping section of the workpiece is convenient to stamp into the stamping groove 8. The workpiece is a steel bar structure, and the above structure is used for eight-shaped stamping.

[0024] Further, in order to allow the upper mold 3 to be raised and lowered, refer to Figure 1 As shown, a top plate 1 is provided above the lower mold 4, columns 5 are installed at the four corners between the lower mold 4 and the top plate 1, and a hydraulic cylinder 2 for lifting is installed between the top plate 1 and the upper mold 3. The top plate 1 is suspended above the lower mold 4 through the columns 5, and the upper mold 3 can be driven to lift and lower above the lower mold 4 through the hydraulic cylinder 2.

[0025] In the present utility model, combined with Figure 3-4 As shown, the interior of both ends of the placement groove 7 of this embodiment is provided with a plurality of receiving grooves 15 at equal distances along the axial direction, and a positioning block 6 and a second spring 14 are installed in each receiving groove 15 from top to bottom in sequence, and the top end of each positioning block 6 extends into the placement groove 7, and the positioning blocks 6 on both sides directly form a positioning area for length positioning of the workpiece.

[0026] As mentioned above, when using the multiple positioning blocks 6 provided by the utility model, the multiple positioning blocks 6 are equidistantly arranged at the two ends of the placement groove 7 through the storage groove 15. When the workpiece is placed in the placement groove 7 and the stamping area of ​​the workpiece is above the stamping groove 8, the positioning block 6 below the workpiece enters the storage groove 15 under gravity, and the length of the workpiece is positioned by the positioning blocks 6 at both ends of the workpiece to prevent the stamping area from leaving the stamping groove 8. When the workpiece is taken out of the placement groove 7, the positioning block 6 pressed into the storage groove 15 is automatically pushed into the placement groove 7 under the elastic force of the second spring 14, which is convenient for the equipment to stamp workpieces of different sizes.

[0027] In the present utility model, combined with Figure 5 As shown, a connecting mounting groove 13 is longitudinally opened below the stamping groove 8 of this embodiment, and a liftable unloading mechanism is installed in the mounting groove 13, and the unloading mechanism is used to push the workpiece out of the stamping groove 8.

[0028] Combination Figure 5 As shown, the material removal mechanism includes a material removal block 10 and a first spring 12 installed from top to bottom, and the top end of the material removal block 10 extends through the punching groove 8.

[0029] As mentioned above, when using the blanking mechanism provided by the utility model, the blanking block 10 in the blanking mechanism is installed below the stamping slot 8 through the mounting groove 13. At the same time, the blanking block 10 is inserted into the stamping slot 8 by the elastic force of the first spring 12. When the workpiece is punched into the stamping slot 8, the blanking block 10 is driven to enter the mounting groove 13. During this process, the blanking block 10 descends on the guide rod 11 through the guide hole 9. When the upper mold 3 is raised, the elastic force of the first spring 12 is greater than the gravity of the workpiece. At this time, the blanking block 10 in the mounting groove 13 is driven to enter the stamping slot 8, thereby ejecting the workpiece in the stamping slot 8 outward, making it easy to remove the stamped workpiece.

[0030] In order to guide the first spring 12 longitudinally, refer to Figure 5 As shown, a guide rod 11 is longitudinally installed in the installation groove 13, a guide hole 9 for accommodating the guide rod 11 is opened at the bottom of the blanking block 10, and the first spring 12 is sleeved on the guide rod 11. The first spring 12 is guided through the guide rod 11, so that the elastic force of the first spring 12 acts on the blanking block 10.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
