Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a multi-punch diversion stamping die. Background Technology

[0002] With the continuous development of industrialized production, various manufacturing industries are increasingly demanding higher production efficiency and precision. Stamping dies, as an indispensable core piece of equipment in the metal processing and plastic molding industries, are widely used in the production of parts for industries such as automobiles, electronics, and home appliances. Traditional stamping dies generally use a single punch structure for stamping operations. Although this structure is simple and easy to manufacture, it still has certain limitations under the demand for efficient and precise production.

[0003] To improve production efficiency, some production equipment uses multiple dies to operate simultaneously, allowing for the stamping of multiple sheets at the same time. However, traditional multi-die parallel stamping methods often suffer from problems such as complex layout, poor synchronization, and difficulty in controlling processing accuracy. Especially when adjusting the die structure, it can easily lead to a decline in the performance of the entire system, affecting the final product quality. Currently, many stamping dies use a stepping feeding structure to gradually advance the sheet. However, traditional stepping feeding structures often suffer from unstable feeding, especially when precisely positioning the sheet. Uneven feeding can cause deviations and errors during the stamping process, directly affecting the quality and consistency of the stamped product.

[0004] With the diversification of stamping materials and the increasing complexity of die structures, extending the service life of dies while ensuring stamping accuracy has become a challenge for the manufacturing industry. Especially under prolonged, high-frequency use, die wear and material fatigue become particularly prominent. Optimizing die structure and materials to extend service life while improving working accuracy has become a key research direction for major manufacturers. In view of this, this paper researches and improves upon existing problems, providing a multi-punch diversion stamping die to address current issues. The aim is to solve problems and enhance practical value through this technology. Utility Model Content

[0006] This utility model relates to a multi-punch flow-dividing stamping die, particularly a die structure for simultaneously performing multi-directional stamping with multiple punches. This die features high production efficiency and good stamping accuracy, and is especially suitable for rapid stamping of large batches of sheet metal.

[0007] The main technical features of this utility model include:

[0008] Fixed mold base: The fixed base of the mold, providing stable support and guiding the movement of the punch, ensuring the precise coordination of each part of the mold during operation.

[0009] Stamping die: By installing several punches, it is possible to perform multi-directional, multi-punch synchronous stamping on the sheet material to ensure the forming effect of the sheet material.

[0011] Ejection die and elastic support: During the stamping process, the ejection die pushes the sheet material to achieve progressive motion through the elastic support, so that the sheet material remains stable during the stamping process and helps to achieve precise positioning of the sheet material.

[0012] Punch: The sheet metal is processed by multi-point synchronous punching through a punch fixed to the bottom surface of the die. This structure can effectively improve production efficiency, especially when processing large quantities of sheets of the same size.

[0013] The technical solution of this utility model provides a high-efficiency and reliable multi-punch flow-dividing stamping die, which has the following advantages:

[0014] High efficiency: By working simultaneously with multiple punches, the stamping speed and production efficiency are greatly improved, making it suitable for high-frequency, high-volume production needs.

[0015] Precision: The stepper feeder assembly ensures precise positioning and uniform feeding of the material through the eccentric movement of the peristaltic block, avoiding material deviation or uneven processing.

[0016] Easy adjustment and maintenance: The mold structure is rationally designed, facilitating adjustment and maintenance. Simple adjustments allow for the adjustment of stamping parameters to meet different production needs, ensuring long-term stable operation of the mold.

[0017] Continuous working capability: This mold can perform continuous stamping processing, ensuring that the sheet after each stamping can quickly complete the next round of processing, which greatly improves production efficiency.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0028] The following is in conjunction with the appendix Figures 1-5 This invention describes a multi-punch flow-dividing stamping die provided by some embodiments of the present invention.

[0029] like Figure 1 As shown, the multi-punch flow-dividing stamping die of this utility model includes a fixed die base 100, a punch 200, a stepping feeding assembly 300, and an ejection die 210. Each component works together through fixed connection and sliding cooperation.

[0030] The fixed mold base 100 is a fixed component of the mold, providing support and ensuring the overall stability of the mold. Guide rods 110 are provided on the surface of the fixed mold base 100 to guide the movement of the punch 200. Multiple guide rails are installed inside the fixed mold base 100 to ensure precise movement of the punch 200 during operation.

[0031] The die 200 includes several punches 220, which are mounted on the bottom surface of the die by fixing bolts. The die 200 performs stamping operations on the die through relative movement with the fixed die base 100. The bottom surface of the die 200 cooperates with the ejector die 210.

[0032] The ejector die 210 and the fixed die base 100 are connected by a sliding fit to ensure the precise positioning of the sheet. When the ejector die 210 moves downward, the elastic support 211 undergoes elastic deformation, which pushes the sheet in a progressive motion through elastic force, thereby ensuring accurate positioning for each stamping.

[0033] The stepper feeding assembly 300 consists of a drive plate 310, a shaft 320, and a peristaltic block 330, and is responsible for the conveying and positioning of the material sheet.

[0034] The drive plate 310 drives the shaft 320 to rotate via an electric motor. Multiple eccentric wheels 321 are mounted on the shaft 320. The electric motor drives the shaft 320 to rotate via a transmission system, thereby causing the peristaltic block 330 to perform eccentric motion.

[0035] An eccentric wheel 321 is fixed to the shaft 320 and is sleeved on the inner side of a peristaltic block 330, driving the peristaltic block 330 to move eccentrically. Under the action of the eccentric wheel, the peristaltic blocks 330 are evenly distributed in the circumferential direction, pushing the sheet material along the mold direction. During the eccentric movement, the peristaltic blocks 330 ensure that the amount of sheet material advanced is consistent each time, thereby ensuring stamping accuracy.

[0036] The rotation of the drive plate 310 and shaft 320 causes the eccentric wheel 321 to drive the peristaltic block 330, pushing the sheet material between the punch 200 and the fixed die base 100. During this process, the elastic support bar 211 on the ejector die 210 pushes the sheet material in a progressive motion through elastic deformation. The distance of each movement remains consistent, ensuring the precise positioning of the sheet material within the die.

[0037] After the sheet material is fed into the die stamping area, the die 200 presses down, and the punch 220 performs a stamping operation on the sheet material. This process ensures the uniformity and high precision of each stamping through the movement of the eccentric wheel 321 and the creeping block 330.

[0038] During the stamping process, the stepping feed assembly 300 continuously drives the material sheet to move, ensuring that the material sheet stamped by each punch 220 is processed in a predetermined order. After each stamping, the drive system controls the peristaltic block 330 to continue moving the material sheet forward, thus proceeding to the next round of stamping.

[0039] This invention features a simple adjustment and maintenance structure. By adjusting the parameter settings on the drive plate 310 and the shaft 320, precise matching between the punch 200 and the fixed die base 100 can be achieved, ensuring the stability of each punching operation.

[0040] Working principle and usage process of this utility model:

[0041] This utility model of multi-punch split-flow stamping die utilizes the relative movement between the punch 200 and the fixed die base 100, the transmission control of the stepping feeding assembly 300, and the cooperative action of the ejector die 210 and the elastic support 211 to ensure the positioning, movement and uniform stamping of the sheet material.

[0042] Stamping process: When the stepper feeding assembly 300 drives the shaft 320 to rotate through the drive plate 310, the eccentric wheel 321 drives the creeping block 330 to move eccentrically in the circumferential direction, pushing the sheet material to be smoothly transferred and positioned between the die 200 and the fixed die base 100.

[0043] Function of ejector die: When ejector die 210 moves downward, elastic support bar 211 undergoes elastic deformation, and pushes the sheet material in a progressive motion through elastic force, so that the sheet material enters the next stamping position in sequence.

[0044] Function of punches: Several punches 220 fixedly installed on the bottom surface of the die 200 move in coordination with the fixed die base 100. The force is applied through the downward pressing action of the punches to achieve the punching and forming of the material sheet.

[0045] Precise positioning: The cooperation between the eccentric wheel 321 and the peristaltic block 330 controls the precise positioning of the sheet, ensuring consistency in each stamping and avoiding sheet offset or uneven stamping.

[0046] Usage process:

[0047] Equipment installation: Fix the mold of this utility model on the equipment base to ensure that the connection between the fixed mold base 100 and the punch 200 is stable and without loosening.

[0048] Loading raw material sheet: Place the sheet to be stamped in front of the stepper feeder 300, ensuring that the sheet is in the initial position.

[0049] Start-up drive: Start-up drive plate 310 and shaft 320, drive eccentric wheel 321 and peristaltic block 330 to start rotating, thereby driving the material sheet into the stamping area.

[0050] Feeding and positioning: During the eccentric movement of the peristaltic block 330, the sheet is pushed to the bottom of the punch 200 and positioned by the ejector die 210 and the elastic support 211.

[0051] Stamping process: When the punch 220 presses down on the die 200, it stamps the sheet material to complete the shape processing.

[0052] Continuous motion: After each stamping is completed, the stepping feeding assembly 300 drives the peristaltic block 330 to move eccentrically, sending the sheet to the next stamping position to achieve continuous processing.
