Description

Technical Field

[0001] The utility model relates to the technical field of continuous dies, in particular to a mesh punching continuous die which utilizes double-slide power to realize abutment first and then punching. Background Art

[0002] In the field of hardware processing, progressive dies are widely used as an advanced mold technology. Progressive dies offer many advantages, including high positioning accuracy between processes, which can accurately guarantee the size and shape accuracy of hardware parts. Furthermore, when using progressive dies, only one positioning is required to complete multiple processes within a single stamping stroke, significantly reducing processing time and handling time between processes, significantly improving production efficiency. Furthermore, the progressive die's high degree of automation reduces manual operation, reducing both labor intensity and safety risks, while also improving material utilization and ultimately lowering production costs.

[0003] There is currently a metal box-shaped product made by direct stamping and drawing of sheet material, which requires a mesh structure to be punched out on its side. Traditionally, a simple side punching structure is often used to complete the mesh punching operation. However, this direct side punching method has obvious disadvantages: when the blade contacts the product, a large impact force is generated. This impact force can have a negative impact on the product, making the punched holes prone to defects, such as irregular edges and deviations in hole size. This in turn affects the overall quality and aesthetics of the product, and to a certain extent limits the production quality and market competitiveness of the metal box-shaped product.

[0004] To sum up, although the continuous die has many advantages in hardware processing, the traditional direct side punching structure cannot meet the requirements of high-quality production for the needs of punching out mesh holes on the side of the above-mentioned specific metal box-shaped products, and there are technical problems that need to be solved urgently. Therefore, it is necessary to develop a new punching technology or improve the existing punching method to overcome these defects and improve the punching quality of the product.

DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-10 In an embodiment of the present invention, a mesh punching continuous die that uses double-position power to achieve first abutment and then punching includes a drawing processing area, a side punching processing area and a step-by-step workpiece handling module 30. A drawing continuous stamping die 40 is provided on the drawing processing area to draw a sheet workpiece into a box-shaped workpiece, and the shape of the workpiece is changed by continuous stamping action; a side punching continuous stamping die 50 is provided on the side punching processing area to punch mesh holes on the side of the box-shaped workpiece. The step-by-step workpiece handling module 30 is provided on both sides of the drawing processing area and the side punching processing area. The step-by-step workpiece handling module 30 is used to carry the workpieces on the drawing continuous stamping die 40 and the side punching continuous stamping die 50 in a step-by-step manner;

[0033] The side punching continuous stamping die 50 includes a side punch upper template 51 and a side punch lower template 52 that cooperate with each other in stamping. When the die is punching, the side punch upper template 51 moves downward to close the mold with the side punch lower template 52. A plurality of side punch mechanisms 60 are provided between the side punch upper template 51 and the side punch lower template 52. Each side punch mechanism 60 is used to punch out a plurality of evenly distributed holes on the side of the box-shaped workpiece, so that the plurality of side punch mechanisms 60 punch out a densely distributed mesh structure on the side of the box-shaped workpiece; during the mold closing process, these side punch mechanisms 60 work synchronously to punch out a plurality of evenly distributed holes on the side of the box-shaped workpiece. The plurality of side punch mechanisms 60 work together to finally punch out a densely distributed mesh structure on the side of the box-shaped workpiece.

[0034] The side punch mechanism 60 includes a box-shaped workpiece positioning assembly 61 installed on the side punch lower template 52, a double-linkage slide block 62 installed on the side punch lower template 52 and located on both sides of the box-shaped workpiece positioning assembly 61, a side punch cutter head 63 installed on the double-linkage slide block 62, and a double-linkage slide block 64 installed on the side punch upper template 51 and docked with the double-linkage slide block 62, wherein the double-linkage slide block 62 is provided with a first guide inclined surface 621 and a second guide inclined surface 622, and the double-linkage slide block 64 is provided with a pair of The first pushing slope 641 connected to the first guide slope 621 and the second pushing slope 642 connected to the second guide slope 622, the double-linkage slide push block 64 drives the side punching cutter head 63 on the double-linkage slide slider 62 to abut the box-shaped workpiece through the cooperation of the first pushing slope 641 and the first guide slope 621, and the double-linkage slide push block 64 drives the side punching cutter head 63 on the double-linkage slide slider 62 to punch the box-shaped workpiece through the cooperation of the second pushing slope 642 and the second guide slope 622.

[0035] In the above technical solution, a box-shaped workpiece positioning assembly 61 is installed on the side punch lower template 52. During the punching process, it contacts a specific part of the box-shaped workpiece to accurately position the workpiece, ensuring that the position of the workpiece during punching is accurate, so that the punching head can accurately punch at the predetermined position.

[0036] The double-linked slide block 62 is installed on the side punch lower template 52 and is located on both sides of the box-shaped workpiece positioning assembly 61, and is provided with a first guide slope 621 and a second guide slope 622. During the mold stamping process, the double-linked slide block 64 cooperates with the first guide slope 621 and the second guide slope 622 of the double-linked slide block 62 through the first pushing slope 641 and the second pushing slope 642 provided thereon. When the double-linked slide block 64 moves downward, it first drives the double-linked slide block 62 to move horizontally through the cooperation between the first pushing slope 641 and the first guide slope 621, thereby realizing the abutment operation of the side punching cutter head 63 on the box-shaped workpiece; then, through the cooperation between the second pushing slope 642 and the second guide slope 622, the double-linked slide block 62 is driven to move further horizontally, thereby completing the punching operation of the side punching cutter head 63 on the box-shaped workpiece. This double-linkage design divides the punching process into two stages: abutment and then punching. In the abutment stage, the side punching head 63 can first lightly contact the workpiece, so that the workpiece has a pre-positioning and buffering process before being subjected to the punching impact force, reducing the adverse effects of the huge impact force at the moment of punching on the workpiece, such as irregular hole edges, aperture deviation and other problems. This design can more accurately control the timing and force of punching, improve the punching quality, ensure higher quality of the punched holes, and improve the overall quality of the product.

[0037] See also Figure 4-5 In the embodiment of the present invention, it is further proposed that a fixing seat 521 corresponding to the double-linkage slide block 62 and a slide reset spring 522 connected to the fixing seat 521 are provided on the side punch lower template 52. The double-linkage slide block 62 is reset by the slide reset spring 522. After the mold completes a punching action, that is, the double-linkage slide block 62 completes the operation of first abutting and then punching under the drive of the double-linkage slide push block 64 and the mold is opened, the slide reset spring 522 will use its own elastic force to pull the double-linkage slide block 62 back to the initial position; this reset mechanism ensures that the double-linkage slide block 62 can be in the accurate initial setting position at the beginning of each punching cycle of the mold, which makes the action of the entire side punching continuous punching mold 50 highly repeatable and stable, and can accurately perform side punching operations on each box-shaped workpiece according to the preset process flow, ensuring the consistency of product processing quality.

[0038] See also Figure 3 and Figure 9 In an embodiment of the present invention, it is further proposed that a continuous drawing stamping die 40 includes a drawing upper template 41 and a drawing lower template 42 that cooperate with each other in stamping. A concave drawing block 43 is provided on the drawing upper template 41, and a sheet workpiece positioning assembly 45 and a convex drawing block 44 are provided on the drawing lower template 42. The concave drawing block 43 and the convex drawing block 44 cooperate with each other to stretch the sheet workpiece on the sheet workpiece positioning assembly 45 into a box-shaped workpiece. The sheet workpiece positioning assembly 45 provided on the drawing lower template 42 can initially position the sheet workpiece and determine its accurate position in the die. The concave drawing block 43 is provided on the drawing upper template 41, and the convex drawing block 44 is provided on the drawing lower template 42. The two cooperate with each other. During the stamping process, when the upper and lower templates are closed, the concave drawing block 43 and the convex drawing block 44 will tightly clamp the sheet workpiece located on the sheet workpiece positioning assembly 45, so that it will not deviate during the stretching deformation process. The initial positioning of the sheet workpiece positioning assembly 45 and the clamping positioning of the concave stretching block 43 and the convex stretching block 44 ensure the position accuracy of the sheet workpiece during the entire stretching process. The precise positioning enables the workpiece to be stretched into a box-shaped workpiece according to the predetermined shape and size, effectively avoiding problems such as irregular stretching shape and dimensional deviation caused by workpiece position offset, thereby greatly improving the processing accuracy and ensuring that the quality of the final box-shaped workpiece meets the design requirements.

[0039] See also Figure 4 、 Figure 5 and Figure 9In the embodiment of the present invention, it is further proposed that the box-shaped workpiece positioning assembly 61 and the sheet-shaped workpiece positioning assembly 45 both include a workpiece placement plate 611a\611b, a guide link 612a\612b, a downward return spring 613a\613b and a downward push plate 614a\614b, wherein,

[0040] In the box-shaped workpiece positioning assembly 61, the workpiece placement plate 611a is guided and connected to the side punch lower template 52, and the guide link 612a is set between the workpiece placement plate 611a and the side punch lower template 52, that is, the workpiece placement plate 611a is guided and connected to the side punch lower template 52 through the guide link 612a, which can ensure its stability during the up and down movement; the downward return spring 613a is set between the workpiece placement plate 611a and the side punch lower template 52, so that in the absence of external force, the workpiece placement plate 611a can rely on the spring force to be lifted to a level higher than the double-linkage sliding block 62; the downward push plate 614a is set on the side punch upper template 51, and the workpiece placement plate 611a is divided into The double-linked sliding block 62 and the double-linked sliding block 64 are in avoidance correspondence, avoiding interference with these components in the initial state. When the box-shaped workpiece needs to be punched, the downward push plate 614a is pressed down along with the side punch template 51 to push the workpiece placement plate 611a down, so that the box-shaped workpiece is accurately moved to between the double-linked sliding blocks 62 on both sides to achieve precise positioning; and in the absence of external force, the workpiece placement plate 611a is lifted to a level higher than the double-linked sliding block 62 by the downward pressing return spring 613a, and the downward pushing plate 614a is used to press the workpiece placement plate 611a downward, so that the box-shaped workpiece is moved between the double-linked sliding blocks 62 corresponding to both sides;

[0041] In the sheet workpiece positioning assembly 45, the workpiece placing plate 611b is guided and connected to the stretching lower template 42, the guide connecting rod 612b is arranged between the workpiece placing plate 611b and the stretching lower template 42, the downward pressure reset spring 613b is arranged between the workpiece placing plate 611b and the stretching lower template 42, and the downward pressure push plate 614b is arranged on the stretching upper template 41. The workpiece placing plate 611b corresponds to the concave stretching block 43 and the convex stretching block 44 respectively, and in the absence of external force, the workpiece placing plate 611b is lifted to a level higher than the convex stretching block 44 by the downward pressure reset spring 613b. The downward pressure push plate 614b is used to push the workpiece placing plate 611b downward, so that the sheet workpiece moves to simultaneously abut against the convex stretching block 44 and the concave stretching block 43, and is stretched into a box-shaped workpiece by both. Similarly, in the sheet workpiece positioning assembly 45, the workpiece placement plate 611b is connected to the lower stretching plate 42 via a guide link 612b. A downward return spring 613b elevates the workpiece placement plate 611b above the convex stretching block 44 in the absence of external force, aligning it with the concave stretching block 43 and the convex stretching block 44 to prevent initial interference. A downward push plate 614b follows the downward pressure of the upper stretching plate 41, pushing the workpiece placement plate 611b downward, allowing the sheet workpiece to abut both the convex stretching block 44 and the concave stretching block 43 for the stretching operation, similarly achieving precise positioning.

[0042] Therefore, precise positioning ensures that subsequent processing operations can be carried out at the correct position. For punching box-shaped workpieces, the accuracy of the punching position can be guaranteed, so that the punched mesh meets the design requirements; for stretching sheet-shaped workpieces, it can ensure that the workpiece is subjected to uniform force during the stretching process, thereby stretching out a box-shaped workpiece with regular shape and accurate size; the corresponding avoidance design effectively avoids the mutual collision and interference of the various components in the non-working state, protects the mold components, reduces the wear of the components caused by unnecessary friction and collision, and extends the service life of the mold. In addition, in the two positioning components, the workpiece placement plate is in a higher position when there is no external force, which makes it convenient for the step-by-step workpiece handling module 30 to place the box-shaped workpiece on the workpiece placement plate of the box-shaped workpiece positioning component 61, or to place the sheet-shaped workpiece on the workpiece placement plate of the sheet-shaped workpiece positioning component 45. After the workpiece is placed, as the upper template of the mold presses down, the downward push plate pushes the workpiece placement plate down, thereby moving the box-shaped workpiece between the double-linkage sliding blocks 62 and the sheet-shaped workpiece between the convex stretching block 44 and the concave stretching block 43.

[0043] See also Figure 1In the embodiment of the utility model, it is further proposed that the step-by-step workpiece handling module 30 includes a horizontal back-and-forth moving mechanism 31 respectively arranged on both sides of the drawing processing area and the side punching processing area, a longitudinal back-and-forth moving mechanism 32 powered by the horizontal moving mechanism, and a plurality of clamps 33 powered by the longitudinal back-and-forth moving mechanism 32 and corresponding to each workpiece placement plate 611a\611b. The plurality of clamps 33 are driven by the horizontal back-and-forth moving mechanism 31 to move in and out of the corresponding workpiece placement plates 611a\611b, and the plurality of clamps 33 are driven by the longitudinal back-and-forth moving mechanism 32 to move between two adjacent workpiece placement plates 611a\611b. The multi-directional movement design ensures that the workpiece is accurately positioned when it is transferred between different processes such as drawing and side punching, thereby avoiding subsequent processing errors caused by inaccurate handling. The multi-directional movement design enables the handling module to adapt to processing areas with different layouts and workpiece placement plate 611a\611b settings. It has strong flexibility and can meet the workpiece handling needs of various complex processing technologies. The automated handling makes the entire production process smoother and more efficient, and the various processing steps can be closely connected, which improves production efficiency and helps to achieve a large-scale, continuous production model.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
