Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and particularly relates to a high-efficiency stamping die for hardware shaft sleeve parts. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. Hardware bushing parts are widely used in many industries such as machinery, automobiles, and electronics. Their production efficiency and quality are crucial to the entire manufacturing process.

[0003] Traditional stamping dies usually have the problem of low efficiency. Generally, a ejection mechanism is used to eject the stamped dies, and then other material collection mechanisms are used to collect the materials. If the ejection and collection of materials need to be completed in two steps by two mechanisms, the overall production efficiency will be reduced. Utility Model Content

[0004] The utility model provides a high-efficiency stamping die for hardware shaft sleeve parts, which solves the problems in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0009] Furthermore, a spring is provided on the inner side of the positioning plate, and a connecting column is fixedly installed on one side of the extrusion block close to the positioning plate. When the workpiece is located at the lower die stamping position, the extrusion block is against one side of the workpiece. After the workpiece is separated from the lower die stamping position, the extrusion block is subjected to elastic force exerted on the workpiece by the spring, bouncing it to one side.

[0010] Furthermore, through holes are provided on the inner side of the positioning plate and corresponding to the punching cutter head, so as to facilitate the positioning of the punching cutter head during the punching process.

[0011] Further, a chute is also formed on the lower die, and a slider is slidably connected to the inner side of the chute. The slider abuts against the rear side of the workpiece to fix the workpiece during stamping.

[0012] Further, when the slider advances along the chute, the extrusion block is also pushed towards the positioning plate, so that the workpiece does not contact the extrusion block during stamping.

[0013] Further, an arc surface is provided on one side of the slider, and a circular arc surface corresponding to the arc surface is provided on one side of the extrusion block, so that the slider can freely slide along the circular arc surface of the extrusion block through the arc surface.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] Embodiment: An efficient hardware bushing part stamping die includes a stamping part and a lower die 2. The stamping part includes an upper die 1 and a stamping tool head 11. A guiding mechanism 3 is also provided between the upper die 1 and the lower die 2. A workpiece 6 is placed on the lower die 2. As Figure 2 shown, a stamping position for fixing and placing the workpiece 6 is correspondingly provided on the lower die 2 opposite to the workpiece 6. As Figure 5 shown, a chute 21 is also opened on the lower die 2. A slider 5 is slidably connected to the chute 21. Before stamping, the workpiece 6 needs to be placed on the chute 21, pushed forward by the slider 5, and the workpiece 6 is fixed on the lower die 2. Then, the upper die 1 is pressed down, driving the stamping tool head 11 provided on the upper die 1 to descend to perform stamping work on the workpiece 6;

[0029] Among them, as Figure 1-2 shown, a positioning plate 4 is also installed at the upper end of the lower die 2. A through hole 41 corresponding to the stamping tool head 11 is also opened inside the positioning plate 4, facilitating the stamping tool head 11 to pass through the through hole 41 to stamp the workpiece 6 during stamping. The positioning plate 4 can also position the stamping tool head 11 to prevent the problem of offset cutting. In addition, an extrusion block 42 is provided along the lower side edge of the positioning plate 4. As Figure 4-5As shown, a spring 43 is fitted inside the positioning plate 4, and a connecting column 44 is provided on one side of the extrusion block 42 close to the positioning plate 4. The connecting column 44 and the spring 43 are fixedly connected to each other. When the slider 5 is pushed forward, the arc surface 51 provided on the side of the slider 5 contacts the arc surface 45 provided on the side of the extrusion block 42, moving the extrusion block 42 towards the positioning plate 4 to avoid contacting the workpiece 6 and ensuring the stamping quality of the workpiece 6.

[0030] As Figure 3 shown, a ejector rod 7 is further provided along the lower side of the workpiece 6. A blanking groove 71 is formed inside the ejector rod 7, so that the waste material punched from the workpiece 6 can fall along the blanking groove 71 and be collected.

[0031] After the stamping of the workpiece 6 is completed, the upper die 1 is reset and the slider 5 is removed. At this time, the extrusion block 42 moves towards the workpiece 6 without the extrusion of the slider 5. Since the thickness of the workpiece 6 is greater than the depth of the stamping position, the extrusion block 42 abuts against the workpiece 6. At this time, the driving mechanism (not shown in the figure) connected to the ejector rod 7 is started to drive the ejector rod 7 to move upward. A positioning hole corresponding to the ejector rod 7 is also formed inside the lower die 2 for the movement of the ejector rod 7. The ejector rod 7 pushes the workpiece 6 upward. When the workpiece 6 is separated from the stamping position of the lower die 2, the elastic force of the spring 43 pushes the workpiece 6 to one side, completing the demoulding and collection of the workpiece 6 and making the overall stamping more efficient.

[0032] 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 principle of the present invention shall be included in the protection scope of the present invention.
