Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping, in particular to a sheet metal stamping positioning auxiliary device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] Stamping is a common metal forming method, which includes blanking, punching, bending, stretching and other processes, and is widely used in various industrial fields. Stamping is also one of the important methods in the sheet metal processing process, which uses the mold to apply pressure to process the metal sheet into the required shape of the parts, thereby obtaining a stamped product.

[0004] Due to the variety of sheet metal structures, each sheet metal product needs to replace the corresponding mold on the stamping machine during stamping. However, the current module installation position on the base cannot be adjusted, which limits the stamping position of the workpiece. In many cases, the punch and the mold on the base need to be replaced simultaneously. The stamping fit between the same punch and different molds at the bottom cannot be adjusted according to actual sheet metal stamping needs. This will greatly increase the investment cost of processing equipment. When frequently performing stamping operations on sheet metal parts with different structures, a lot of equipment adjustment and debugging time needs to be added, which affects production efficiency. Utility Model Content

When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: See Figures 1 to 4 The present embodiment discloses a sheet metal stamping positioning auxiliary device, including a base plate 1 and a movable component, wherein the movable component is composed of a first movable block 2 and a second movable block 5 which are stacked and can adapt to the stamping action of the punch of the stamping machine tool, and complete the same punch with a variety of tooling position changes to meet the needs of a variety of stamping methods.

[0031] The base plate 1 is a horizontally arranged rectangular plate body, which serves as the main bearing structure and is arranged at the bottom for connecting to an external stamping machine.

[0032] Furthermore, guide holes 12 are provided around the base plate 1, and four guide holes 12 penetrate the base plate 1 longitudinally. In actual use, the guide holes 12 are provided for the guide rods on the punch assembly to pass through, forming a vertical guide structure of the punch, so that the punch can maintain stable vertical up and down movement during punching.

[0033] Combination Figure 1 and Figure 2 Two guide rails 11 are provided at the center of the top surface of the bottom plate 1, and the longitudinal section profile of the guide rail 11 is a "T"-shaped structure. The long side direction of the guide rail 11 is defined as the front-to-back direction, and the short side direction of the guide rail 11 is defined as the left-to-right direction.

[0034] The first movable block 2 is controllably movably connected to the top of the bottom plate 1, and can perform lateral linear displacement relative to the bottom plate 1. Specifically, the first movable block 2 is a rectangular block structure, and two connecting blocks 3 are connected to the front and rear sides thereof, respectively. The connecting block 3 is arranged between the first movable block 2 and the bottom plate 1. One side of the connecting block 3 is connected and fixed to the first movable block 2 (specifically, connected and fixed by welding), and the bottom of the connecting hole forms a concave-convex clamping guide limit structure with the bottom plate 1. Specifically, a track groove 23 adapted to the guide rail 11 is provided at the bottom of the connecting block 3, and the track groove 23 is concave-convexly sleeved on the guide rail 11 to form the guide limit structure.

[0035] Further, combined with Figure 4 As shown, the connecting block 3 is a trapezoidal block with an inclined end face structure on the top. A countersunk threaded hole is provided on the inclined end face. The countersunk threaded hole longitudinally passes through the connecting hole for installing a positioning bolt 4. The positioning bolt 4 is threadedly connected to the connecting block 3 when in use. After tightening, the bottom of the positioning bolt 4 is tightly abutted against the base plate 1 to form a locking and positioning structure between the first movable block 2 and the base plate 1. That is to say, when each positioning bolt 4 is loosened, the first movable block 2 can stably and reliably slide back and forth along the guide rail 11 with the help of the connecting block 3 to adjust its position in the front and rear directions. After adjustment, the positioning bolt 4 is locked to keep the first movable block 2 fixed relative to the base plate 1.

[0036] In order to make the relative displacement between the first movable block 2 and the base plate 1 more stable and reliable, the bottom surface of the connecting block 3 is flush with the ground of the first movable block 2, and the track groove 23 transversely penetrates the connecting block 3 and the first movable block 2, which greatly increases the connection area between the guide rail 11 and the track groove 23, so that the guiding effect is better.

[0037] The second movable block 5 is controllably movably connected to the first movable block 2, and can perform lateral linear displacement relative to the first movable block 2, and the displacement direction is perpendicular to the displacement direction of the first movable block 2. In this embodiment, the first movable block 2 can be displaced in the front-to-back direction, and the second movable block 5 can be displaced in the left-to-right direction. Specifically, an inner cavity 21 with a sink structure is provided on the top of the first movable block 2, and the second movable block 5 is arranged in the inner cavity 21 to form a stacked structure. A limiting boss 22 is provided in the inner cavity 21, and a limiting sink 53 adapted to the limiting boss 22 is provided on the side wall of the second movable block 5. The limiting sink 53 and the limiting boss 22 form an abutting limiting structure, and the second movable block 5 can stably and reliably slide back and forth in the long side direction (i.e., the left-to-right direction) of the limiting boss 22.

[0038] A screw rod 6 is provided on one side of the second movable block 5, and the screw rod 6 is parallel to the long side direction of the limiting boss 22, and the inner end of the screw rod 6 is pivotally connected to the second movable block 5. Figure 3 As shown, a T-slot 52 is provided on one side of the second movable block 5, and the inner end of the screw rod 6 is inserted into the T-slot 52 and fixedly connected with a limiting nut 61. When the screw rod 6 rotates, the limiting nut 61 will be stably stuck in the T-slot 52, so that the screw rod 6 will not move axially outward. The outer end of the screw rod 6 passes through the first movable block 2 and forms a threaded connection structure through the connecting nut 62. A plug-in groove 63 is provided at the outer end of the screw rod 6. In this embodiment, the plug-in groove 63 is a hexagonal countersunk hole, which can be adapted to a hexagonal wrench to control the rotation operation of the screw rod 6. When the screw rod 6 rotates forward and backward, it can drive the second movable block 5 to move in the left and right directions relative to the first movable block 2.

[0039] The second movable block 5 is provided with a tooling slot 51 for accommodating the sheet metal part to be punched.

[0040] During the specific implementation process, the first movable block 2 and the second movable block 5 can be adjusted in the front-to-back and left-to-right directions, so that the position of the tooling slot 51 relative to the position of the punch can be adjusted and controlled in an orderly manner, and then the stamping position can be adjusted according to the structural differences of the actual sheet metal parts, so that the punch structure can be utilized as much as possible, so that the same punch structure can be adjusted according to the adjustment of the tooling position of the bottom workpiece without replacement, and a variety of stamping effects can be achieved. Therefore, the equipment utilization rate can be greatly improved and the investment in production costs can be reduced. Accordingly, the convenient position adjustment of the movable component can be used to facilitate and quickly complete equipment adjustments, and product replacement operations can be quickly and conveniently performed to achieve the purpose of improving production efficiency.

[0041] Example 2: Based on Example 1, Figure 5 As shown, in order to further enhance the structural flexibility of the device, a detachable panel 54 is provided on the top of the second movable block 5 , and the tooling slot 51 is provided on the top of the panel 54 .

[0042] Furthermore, the panel 54 is connected to the second movable block 5 via a plurality of countersunk holes 55 and bolts, so as to facilitate the disassembly and assembly of the panel 54. This structure enables the structural replacement of the tooling slot 51 according to the structure of the actual sheet metal part, so as to meet the stamping requirements of sheet metal parts with different structures.

[0043] Embodiment 3: Based on Embodiment 1, Figure 6 As shown, in order to ensure that the positions of the first movable block 2 and the second movable block 5 can be effectively controlled, the first movable block 2 and the second movable block 5 are respectively provided with a first marking line 7 and a second marking line 8 on their displacement paths, wherein the first marking line 7 is arranged on the top surface of the first movable block 2, and is distributed in the left and right directions, for matching the position comparison of the edge line of the second movable block 5, and the second marking line 8 is arranged on the bottom plate 1, and is distributed in the front and back directions, for matching the position comparison of the edge line of the first movable block 2.
