Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to an adjustable stamping die and a method thereof. Background Art

[0002] In the field of stamping die manufacturing and application, traditional stamping operations have long relied on manual operation. From workpiece positioning, stamping execution to material collection, the entire process is not only time-consuming and labor-intensive, but also involves high safety risks. Especially in the stamping process, workers need to get close to the die and manually place and remove the workpiece. Accidents are very likely to occur during this process, posing a serious threat to the workers' lives and safety. In addition, the degree of automation of traditional molds is low, and it is difficult to improve production efficiency. For workpieces with complex shapes or high precision requirements, manual operation often cannot ensure the consistency of product quality.

[0003] With the rapid development of industrial automation, some stamping dies with automatic feeding, stamping and unloading functions have gradually appeared on the market. These dies have improved production efficiency and reduced safety risks to a certain extent. However, these dies still have many shortcomings in design, especially in the unloading mechanism and workpiece collection system.

[0004] In terms of the unloading mechanism, although some molds have introduced automatic unloading mechanisms, the design is unreasonable, such as unstable unloading action and inaccurate unloading position. These problems may not only cause damage to the workpiece, but also affect the continuous operation capacity of the mold. In addition, the unloading mechanism of some molds is too complicated, the maintenance cost is high, and failures occur frequently in actual applications, affecting the stable operation of the production line.

[0005] In terms of workpiece collection systems, traditional molds usually use fixed-position collection boxes. After each stamping, workers need to manually take the workpiece out of the mold and put it into the collection box. This method is not only inefficient, but also increases the labor intensity of workers. Although some molds have tried to introduce automatic collection systems, they often have poor collection effects due to unreasonable designs or immature technologies. Problems such as workpiece accumulation and missed collection often occur. For this reason, we provide an adjustable stamping mold and method thereof. Summary of the invention

[0012] Furthermore, the material receiving structure includes a vertical fixing plate fixedly connected to the lower end surface of the workbench, a ramp plate fixedly connected between the two vertical fixing plates, a rectangular opening is opened on the surface of the workbench, a collecting box is arranged on the inner wall of the rectangular opening, a U-shaped block is vertically fixedly connected to the inner side wall of the rectangular opening, sliding blocks are fixedly installed on the two end surfaces of the collecting box, and the sliding blocks are slidably connected to the inner wall of the collecting box, and a telescopic component is connected to the lower end of the collecting box, which is used for the sliding block to be detached from the U-shaped block after the collecting box receives materials to a certain extent.

[0015] Furthermore, the bevel gear 2 is meshedly connected with the bevel gear 1, and the design size of the bevel gear 1 is twice that of the bevel gear 2, so that the bevel gear 2 can rotate half a circle when the bevel gear 1 rotates a quarter circle.

[0017] Furthermore, the upper end of the spring three is fixedly connected to the lower end surface of the collection box, and the lower end of the spring three is fixedly connected to the upper end surface of the moving wheel.

[0018] Furthermore, a method for using an adjustable stamping die is provided, comprising the adjustable stamping die according to the claim, comprising the following steps:

[0019] Start the hydraulic cylinder to lower the stamping template, and the touch ball in the L-shaped plate at the upper end of the stamping template touches the triangular plate at the end of the load-bearing plate;

[0020] After the triangle plate is stressed, the n-type plate moves by the sliding sleeve in the strip placement groove and the elastic action of the spring 1; when the stamping template is about to contact the stamped part, the n-type plate has moved to the other side of the bearing plate; and in this process, the force is rotated, and the stamped part is not pushed down under the limit of the limit block;

[0021] After the stamping is completed, the hydraulic cylinder drives the stamping template to rise. When it rises to a certain height, the L-shaped touch rod touches the second transverse fixing rod outside the plug rod, causing the plug rod to rotate in the sleeve. During this period, due to the limitation of the one-way limit mechanism, the plug rod drives the hollow tube to rotate during the continuous upward movement of the stamping template. In this way, the upper linkage component is used to rotate the bearing plate, so that the blanking edge of the bearing plate is transferred from the front to the back. When the stamping template is lowered for stamping, the plug rod will be reset under the action of the torsion spring, and the one-way limit mechanism will be used to prevent the hollow tube from rotating during the entire reset process, thereby ensuring the stability of the bearing plate during the next stamping.

[0022] Finally, when the number of workpieces in the collection box reaches a certain amount, the telescopic assembly at the lower end of the collection box is compressed, causing the sliding blocks at both ends of the collection box to slide out of the U-shaped blocks, realizing automatic detachment of the collection box for easy cleaning and replacement.

[0023] Beneficial effects of the present invention:

[0024] The present invention provides a material unloading mechanism so that the flip plate can be moved to the other side of the carrier plate during stamping to reserve space for stamping. After the stamping is completed, the n-type plate is reset during the upward movement of the stamping template. At this time, the flip plate will no longer flip due to the cooperation of the groove plate, and the stamped parts can be pushed down while the stamping template is moving upward, thereby avoiding the danger and trouble caused by manual unloading and achieving a better automatic unloading purpose.

[0025] The present invention sets a linkage component, and the linkage component cooperates with the second touching cross-fixing rod and the L-shaped touching rod, so that the hollow tube can rotate during the continuous upward movement of the stamping template; then cooperates with the conical gear, the belt pulley and the linkage belt to allow the shaft rotating rod to drive the carrying plate to rotate; during this period, due to the setting of the size, the carrying plate can be rotated by 180 degrees, thereby changing the unloading side of the carrying plate, so that the collection boxes arranged before and after the workbench can be staggered and continuously collected, so that more finished products can be collected, and better unloading effect is achieved while increasing the operation time of the equipment.

[0026] The present invention arranges a telescopic component, which cooperates with a U-shaped block and a sliding block. When the number of workpieces in the collection box reaches a certain number, the gravity of the workpieces will compress the telescopic component, so that the sliding blocks at both ends of the collection box slide out of the U-shaped block, which is convenient for rapid removal and processing after unloading, and further improves the unloading effect.

[0037] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0038] Example

[0039] like Figure 1-Figure 9As shown, an adjustable stamping die proposed in one embodiment of the present invention comprises a workbench 1 and an n-type frame 2 fixedly mounted on one side of the workbench 1. A hydraulic cylinder 3 is fixedly mounted on the upper part of the n-type frame 2, and the output end of the hydraulic cylinder 3 is connected to the stamping template 4. A shaft rotating rod 5 is installed at the center of the workbench 1 through a bearing, and a bearing plate 6 is welded on the top of the shaft rotating rod 5 for placing the stamped parts. A limit block 7 is fixedly connected to the edge of one side of the bearing plate 6 to prevent the stamped parts from falling during the stamping process. A blanking mechanism 8 is connected to the end of the bearing plate 6, which is composed of a strip rod 81, a strip placement groove 82, a transverse fixing rod 83, a spring 84, a sliding sleeve block 85, an n-type plate 86, a groove plate 87, a flip plate 88 and a triangular plate 9, wherein the triangular plate 9 is used to trigger the blanking action. The n-type frame 2 is connected to the shaft rotating rod 5 through a linkage component to realize the rotation adjustment of the bearing plate 6. The front and back sides of the workbench 1 are both provided with a material receiving structure for collecting the workpiece after stamping; when the hydraulic cylinder 3 drives the stamping template 4 to descend, the touch ball 12 on the L-shaped plate 10 will first contact the triangular plate 9, triggering the action of the material unloading mechanism 8, so that the n-shaped plate 86 and the flip plate 88 move to make room for the workpiece after stamping. After the stamping is completed, the carrier plate 6 rotates 180° through the linkage component, so that the workpiece falls onto the material receiving structure on the other side of the workbench 1.

[0040] Among them, the connection between the groove plate 87 and the flip plate 88 allows the flip plate 88 to touch the stamped part and rotate when the stamping template 4 is pressed down, and cooperate with the upper limit block 7, so that the n-type plate 86 can be smoothly moved to the other side of the supporting plate 6; and when the stamping template 4 is moved up, the n-type plate 86 will be reset, and the flip plate 88 cannot rotate at this time, which will push the stamped part to move and then fall into the collection box 34.

[0041] Furthermore, the linkage component is composed of a hollow tube 13, a connecting rod 14, a sleeve tube 15, a plug rod 16, a torsion spring 17 and a one-way limiting mechanism. The hollow tube 13 is connected to the n-shaped frame 2 through a bearing, and a sleeve tube 15 is fixed to the lower end of the connecting rod 14, and the plug rod 16 is inserted into the sleeve tube 15. The two can rotate relative to each other, and the torsion spring 17 provides a reset force. The one-way limiting mechanism ensures that the plug rod 16 can drive the hollow tube 13 to rotate in a specific direction; when the stamping template 4 rises to a certain height, the L-shaped touch rod 40 will contact the transverse fixing rod 39 on the plug rod 16, so that the plug rod 16 rotates in the sleeve tube 15, and then drives the hollow tube 13 to rotate through the one-way limiting mechanism. The rotation of the hollow tube 13 is achieved through the meshing of the bevel gear 1 23 and the bevel gear 2 26, as well as the transmission of the belt pulley 1 27, the belt pulley 2 28 and the linkage belt 29, which eventually causes the shaft rotating rod 1 5 and the bearing plate 6 to rotate 180°.

[0042] Among them, the stamping template 4 will allow the L-shaped touch rod 40 to touch the transverse fixing rod 2 39 during the continuous upward movement, thereby causing the plug-in rod 16 to reverse. At this time, the arc block 22 drives the hollow tube 13 to rotate due to the plane contact with the inner wall of the opening groove 18; when the transverse fixing rod 2 39 is in a vertical state, the bevel gear 1 23 rotates a quarter of a circle, and the bevel gear 2 26 rotates half a circle, thereby allowing the unloading edge of the supporting plate 6 to rotate from the original front side to the back side, so that the front and rear two collecting boxes 34 can intermittently receive materials to achieve a better unloading effect.

[0043] Furthermore, the material receiving structure includes a vertical fixing plate 30, a ramp plate 31, a rectangular opening 32, a U-shaped block 33 and a collection box 34. The vertical fixing plate 30 is fixed to the lower surface of the workbench 1, and a ramp plate 31 is formed between the two vertical fixing plates 30 to guide the workpiece after stamping to slide down. The rectangular opening 32 is opened on the surface of the workbench 1, the U-shaped block 33 is fixed on the inner wall of the rectangular opening 32, and the two end surfaces of the collection box 34 are provided with sliding blocks 35, which can slide in the U-shaped block 33. The lower end of the collection box 34 is connected with a telescopic assembly, including a second telescopic rod 36, a third spring 37 and a moving wheel 38.

[0044] When the number of workpieces in the collection box 34 reaches a certain value, the gravity of the workpieces will compress the telescopic assembly, causing the sliding blocks 35 at both ends of the collection box 34 to slide out of the U-shaped block 33, making it easier to clean and replace.

[0045] Furthermore, the one-way limiting mechanism is composed of an open slot 18 provided at the end of the hollow tube 13 and a rectangular groove 19 provided at the periphery of the plug-in rod 16. A telescopic rod 1 20 and a spring 21 are provided in the rectangular groove 19, and an arc block 22 is fixed to the end of the telescopic rod 1 20. When the plug-in rod 16 rotates in the sleeve 15, the arc block 22 will enter and exit the open slot 18 under the action of the spring 21, thereby limiting the rotation direction of the plug-in rod 16.

[0046] Further, the telescopic assembly includes a second telescopic rod 36, a third spring 37 and a moving wheel 38. When the workpieces in the collection box 34 reach a certain weight, the third spring 37 will be compressed, causing the collection box 34 to drop, and the sliding block 35 will slide out of the U-shaped block 33 to achieve automatic falling off.

[0047] Furthermore, the meshing relationship between the bevel gear 2 26 and the bevel gear 1 23 ensures that when the bevel gear 1 23 rotates a quarter turn, the bevel gear 2 26 rotates a half turn. This design allows the carrier plate 6 to rotate 180° each time, ensuring that the workpiece can be accurately transferred from one side to the other.

[0048] Furthermore, one end of the spring 1 84 is fixed to the end wall of the strip-shaped placement groove 82, and the other end is fixed to one end surface of the sliding sleeve 85. When the triangular plate 9 is subjected to the pressure of the touch ball 12, the sliding sleeve 85 will slide in the strip-shaped placement groove 82, and at the same time compress the spring 1 84, so as to realize the movement of the n-type plate 86.

[0049] Further, the upper end of the spring three 37 is fixed on the lower end surface of the collection box 34, and the lower end is fixed on the upper end surface of the moving wheel 38. When the workpieces in the collection box 34 reach a certain weight, the spring three 37 will be compressed, causing the collection box 34 to drop and automatically fall off.

When it rises to a certain height, the L-shaped touch rod (40) touches the second transverse fixing rod (39) on the periphery of the plug rod (16), causing the plug rod (16) to rotate in the sleeve (15); during this period, due to the limitation of the one-way limit mechanism, the plug rod (16) drives the hollow tube (13) to rotate during the continuous upward movement of the stamping template (4); thereby cooperating with the upper linkage component to rotate the bearing plate (6) 180°, so that the blanking edge of the bearing plate (6) is transferred from the front to the back; and when the stamping template (4) is lowered for stamping, the plug rod (16) will be reset under the action of the torsion spring (17), and during the entire reset process, the one-way limit mechanism will be cooperated to prevent the hollow tube (13) from rotating, thereby ensuring the stability of the bearing plate (6) during the next stamping; Finally, when the number of workpieces in the collection box (34) reaches a certain number, the telescopic assembly at the lower end of the collection box (34) is compressed, so that the sliding blocks (35) at both ends of the collection box (34) slide out from the U-shaped block (33), so that the collection box (34) automatically falls off, which is convenient for cleaning and replacement.
