Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a manually adjustable needle roller die. Background Technology

[0002] The stamping process of V-shaped sheet metal parts has a wide range of applications. Currently, in the production of V-shaped sheet metal parts, the forming lower die structure is fixed and the forming angle of the V-shaped sheet metal parts cannot be adjusted. On the other hand, the existing forming lower die has a single function, and one machine cannot switch between forming V-shaped sheet metal parts and U-shaped sheet metal parts.

[0003] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0004] The purpose of this invention is to provide a manually adjustable needle roller die, which is easy to adjust, has multiple functions, effectively reduces processing steps, lowers production costs, and is highly efficient.

[0005] This utility model provides a manually adjustable needle roller die, including a base, wheel sets, an external hexagonal sprocket, a sprocket, a left-hand ball screw, a right-hand ball screw, a left-hand ball slider, a right-hand ball slider, a chain, a left-side forming die, and a right-side forming die. The wheel sets are connected to both ends of one side of the base, and the two wheel sets are symmetrically arranged about the center line of the base. Each wheel set includes a first gear, a second gear, a third gear, and a fourth gear, all of which are rotatably connected to one side of the base and are sequentially meshed. The left-hand ball screw and the right-hand ball screw are respectively fixedly connected to the first gear and the third gear at one end of one side of the base. The right-hand ball screw and the left-hand ball screw are respectively fixedly connected to the first gear and the third gear at one end of one side of the base; the left-hand ball screw and the right-hand ball screw are arranged in parallel; a left-hand ball slider is threadedly connected to the left-hand ball screw, and a right-hand ball slider is threadedly connected to the right-hand ball screw. Both the left-hand ball slider and the right-hand ball slider are slidably connected to the top of the base; the two ends of the bottom of the left molding mold are respectively connected to the two left-hand ball sliders by bearings, and the two ends of the bottom of the right molding mold are respectively connected to the two right-hand ball sliders by bearings; the sprocket is fixedly connected to the other side of the third gear, the chain is sleeved on the two sprockets, and the external hexagon is fixedly connected to the fourth gear.

[0006] Using the above technical solution, during use, a hexagonal socket wrench is used to rotate one of the outer hexagonal sockets. The outer hexagonal socket drives the fourth gear to rotate, the fourth gear drives the third gear to rotate, the third gear drives the second gear to rotate, and the second gear drives the first gear to rotate. Simultaneously, through chain transmission, the two wheel sets move synchronously. The left-hand and right-hand ball screws rotating at the upper and lower ends drive the left and right forming molds to move closer or further apart through the left-hand and right-hand ball sliders, thereby adjusting the forming angle of the V-shaped sheet metal part. When the distance between the left and right forming molds is large enough, U-shaped sheet metal parts can also be formed.

[0007] Furthermore, four sliding grooves are provided on the top of the base, and two left-handed ball sliders and two right-handed ball sliders are slidably connected in the four sliding grooves respectively.

[0008] Furthermore, both the left and right forming molds have L-shaped cross-sections, and connecting holes are provided at both ends of both the left and right forming molds. The bearings are fixedly fitted on both the left-hand and right-hand ball sliders, and the bearings are provided with mounting holes. By passing bolts through the connecting holes and the mounting holes, the two ends of the left forming mold are respectively connected to the two left-hand ball sliders, and the two ends of the right forming mold are respectively connected to the two right-hand ball sliders.

[0009] Furthermore, both the left and right forming molds are provided with arc-shaped grooves at their upper ends, and needle rollers are rotatably connected in the arc-shaped grooves.

[0010] Furthermore, multiple sliding notches are provided at equal intervals on the left molding die and the right molding die.

[0011] This utility model's manually adjustable needle roller die operates by using a hexagonal socket wrench to rotate one of the outer hexagonal gears. The outer hexagonal gear drives the fourth gear, which in turn drives the third gear, which in turn drives the second gear, which in turn drives the first gear. Simultaneously, a chain transmission enables the two wheel sets to move synchronously. The left-hand and right-hand ball screws rotating at their upper and lower ends move the left and right forming dies closer together or further apart via left-hand and right-hand ball sliders, thus allowing adjustment of the forming angle of V-shaped sheet metal parts. When the distance between the left and right forming dies is large enough, U-shaped sheet metal parts can also be formed. It is easy to adjust, has multiple functions, effectively reduces processing steps, lowers production costs, and is highly efficient. Attached Figure Description

Figure 2 for Figure 1 A side cross-sectional view of the base of a manually adjustable needle roller die. Figure 3 for Figure 1 A cross-sectional view of the base of the manually adjustable needle roller die from another side. Please refer to... Figure 1 , Figure 2 , Figure 3The manually adjustable needle roller die provided in this embodiment includes a base 1, a wheel assembly 2, an external hexagonal jack 3, a sprocket 4, a left-hand ball screw 5, a right-hand ball screw 6, a left-hand ball slider 7, a right-hand ball slider 8, a chain 9, a left-hand forming die 100, and a right-hand forming die 200. The wheel assembly 2 is connected to both ends of one side of the base 1, and the two wheel assemblies 2 are symmetrically arranged about the center line of the base 1. Each wheel assembly 2 includes a first gear 21, a second gear 22, a third gear 23, and a fourth gear 24. The first gear 21, the second gear 22, the third gear 23, and the fourth gear 24 are all rotatably connected to one side of the base 1, and are sequentially meshed. The left-hand ball screw 5 is fixedly connected to the first gear 21 and the third gear 23 at one end of one side of the base 1. The right-hand ball screw 6 and the left-hand ball screw 5 are respectively fixedly connected to the first gear 21 and the third gear 23 at the other end of one side of the base 1; the left-hand ball screw 5 and the right-hand ball screw 6 are arranged in parallel; the left-hand ball slider 7 is threadedly connected to the left-hand ball screw 5, and the right-hand ball slider 8 is threadedly connected to the right-hand ball screw 6. The left-hand ball slider 7 and the right-hand ball slider 8 are slidably connected to the top of the base 1; the two ends of the bottom of the left molding mold 100 are respectively connected to the two left-hand ball sliders 7 by bearings, and the two ends of the bottom of the right molding mold 200 are respectively connected to the two right-hand ball sliders 8 by bearings; the sprocket 4 is fixedly connected to the other side of the third gear 23, the chain 9 is sleeved on the two sprockets 4, and the external hexagon 3 is fixedly connected to the fourth gear 24.

[0031] It should be noted that, in use, the manually adjustable needle roller die of this utility model is operated by rotating one of the outer hexagonal socket wrenches 3 using a hexagonal socket wrench. The outer hexagonal socket wrench 3 drives the fourth gear 24 to rotate, the fourth gear 24 drives the third gear 23 to rotate, the third gear 23 drives the second gear 22 to rotate, and the second gear 22 drives the first gear 21 to rotate. At the same time, through the transmission of the chain 9, the two wheel sets 2 move synchronously. The left-hand ball screw 5 and the right-hand ball screw 6, which rotate at the upper and lower ends, will drive the left forming die 100 and the right forming die 200 to move closer or further apart through the left-hand ball slider 7 and the right-hand ball slider 8. This allows for the adjustment of the forming angle of the V-shaped sheet metal part. When the distance between the left forming die 100 and the right forming die 200 is large enough, the forming of the U-shaped sheet metal part can also be achieved.
