Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a die-casting forming and punching equipment. Background Technology

[0002] Die-casting punching equipment is a precision machine specifically designed for the subsequent processing of metal workpieces. Its main function is to remove burrs, flash, and excess material generated during the die-casting process through high-pressure punching, while simultaneously shaping and correcting the dimensions of the workpiece. This type of equipment typically combines a hydraulic drive system with precision mold design and is widely used in the production processes of aluminum and magnesium alloy workpieces.

[0003] Combining the workpiece feeding and unloading process with the forming and punching equipment can effectively improve processing speed and processing continuity during mass production. However, in the existing technology, most die-casting forming and punching equipment uses conveyor belt feeding and push rod unloading. This feeding and unloading structure is relatively complex. When feeding with a conveyor belt, the workpiece is prone to displacement due to vibration, making it difficult to ensure the positioning accuracy of the workpiece entering the stamping die. At the same time, different equipment is required to complete the feeding and unloading operations, which increases the manufacturing cost of the equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a die-casting forming and punching equipment that integrates the feeding and discharging structures into the die-casting forming and punching equipment, thereby improving the positioning accuracy and overall integrity of the equipment.

[0005] The technical solution of this utility model is as follows:

[0006] A die-casting forming and punching equipment includes a punching structure, a stamping die, and a worktable. The stamping die is located on the side of the punching structure facing the ground, and the worktable is located on the side of the stamping die facing the ground. The side of the stamping die facing the punching structure has a first limiting hole for facilitating the positioning of the workpiece. The side of the worktable away from the stamping die has an automatic feeding and discharging structure. The worktable is parallel to the installation direction of the device and has a workpiece positioning structure on the side facing the automatic feeding and discharging structure.

[0007] In one possible implementation, the workpiece positioning structure includes a positioning mold and a second limiting hole. The positioning mold is located on the side of the worktable away from the ground, and the second limiting hole is located on the side of the positioning mold facing the automatic feeding and discharging structure. The positioning mold has a limiting groove on the side near the worktable and a positioning inlet on the side away from the worktable.

[0008] In one possible implementation, the automatic feeding and discharging structure includes a Y-axis moving component, a Z-axis moving component that drives the Y-axis moving component to reciprocate in the Z-axis direction, and an X-axis moving component that drives the Z-axis moving component to reciprocate in the X-axis direction. The Y-axis moving component includes a third guide rail, a third drive stage, and a third driver for driving the third drive stage to reciprocate in the Y-axis direction. The third guide rail is located on the side of the Z-axis moving component away from the ground. The third drive stage is slidably connected to the third guide rail. The output end of the third driver is detachably connected to the side of the third drive stage away from the worktable.

[0009] In one possible implementation, the third drive platform is provided with an infeed column, a workpiece clamping block, an outlet column, and a workpiece lifting block on the side facing the worktable. The workpiece clamping block is located on the side of the infeed column away from the ground and forms a workpiece clamping area with the infeed column. The workpiece lifting block is located on the side of the outlet column facing the ground and forms a workpiece transport area with the outlet column.

[0010] In one possible implementation, a feed block and a discharge block are respectively provided between the feed column, the discharge column and the third drive platform to facilitate the installation of the feed column and the discharge column.

[0011] In one possible implementation, quick-connect fixing heads are provided at the connection points between the discharge column, the inlet column and the discharge block, and the inlet block, respectively, and the quick-connect fixing heads are detachably connected to the inlet block and the discharge block.

[0012] In one possible implementation, the worktable is provided with a scrap discharge structure on the side facing the stamping die;

[0013] The waste material discharge structure includes a waste material discharge plate and a discharge plate support column. The discharge plate support column is located on the side of the workbench away from the ground. One end of the waste material discharge plate is located on the side of the discharge plate support column away from the ground, and the other end is located on the side of the workbench away from the discharge plate support column. The side of the waste material discharge plate away from the ground is provided with a waste material guide slope.

[0014] In one possible implementation, the scrap blanking plate has a blanking plate mounting groove on the side facing the stamping die, and the scrap blanking plate is sleeved on the outside of the stamping die through the blanking plate mounting groove.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] When feeding and discharging are required, the drive assembly drives the feeding moving block to align the feeding column and the discharging column of the feeding moving block with the workpiece to be processed in the positioning mold and the punched part of the stamping mold, respectively. Then the workpiece to be processed is transported to the stamping mold through the drive assembly, and the die-casting part is also transported to the next process. At this time, the punching structure moves downward to cooperate with the stamping mold to complete the punching work of the workpiece to be processed.

[0017] Integrating the feeding and discharging structures into the die-casting and punching equipment reduces the floor space required and allows it to adapt to various production lines or workshop environments, improving the overall integrity and adaptability of the equipment. Simultaneously, dual positioning of the workpiece is achieved through the first limiting hole of the stamping die and the second limiting hole of the positioning die, improving positioning accuracy and ensuring the processing quality of the equipment.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-6 As shown, this embodiment proposes a die-casting forming and punching equipment for processing workpieces with symmetrical through holes at both ends, through-hole grooves on the outer walls of both the punched part and the workpiece to be processed, and an arc-shaped cross-section. The equipment structure includes a punching structure 1, a stamping die 2, and a worktable 3. The stamping die 2 is located on the ground-facing side of the punching structure 1, and the worktable 3 is located on the ground-facing side of the stamping die 2. The worktable 3 provides a stable mounting foundation for the punching structure 1, the stamping die 2, and subsequent structures, ensuring the processing stability of this embodiment.

[0030] In this embodiment, the stamping die 2 has been adapted to accommodate the workpiece. A first limiting hole 21 is provided on the side facing the punching structure 1 to facilitate workpiece positioning, allowing the edge of the punched workpiece to be fitted into the first limiting hole 21, thus improving positioning accuracy. Simultaneously, the size of the first limiting hole 21 can be adjusted according to the actual condition of the punched workpiece; this will not be elaborated upon further in this embodiment.

[0031] Furthermore, the workbench 3 is provided with an automatic feeding and discharging structure 4 on the side away from the stamping die 2, and a workpiece positioning structure 5 is provided on the side of the workbench 3 that is parallel to the installation direction of the device and faces the automatic feeding and discharging structure 4. The two are integrated into the punching equipment and cooperate with each other to form a small processing production line, which not only improves the overall integrity of the equipment, but also improves production accuracy and efficiency while ensuring processing quality.

[0032] In this embodiment, the workpiece positioning structure 5 includes a positioning mold 51 and a second limiting hole 52. The positioning mold 51 is located on the side of the worktable 3 away from the ground. The side of the positioning mold 51 away from the worktable 3 can abut against the conveyor belt. The side of the positioning mold 51 near the worktable 3 is provided with a limiting groove 53, and the side away from the worktable 3 is provided with a positioning inlet 54. After the workpiece is transported by the conveyor belt, it enters the positioning mold 51 from the positioning inlet 54 and abuts against the limiting groove 53, which improves the positioning accuracy of this embodiment.

[0033] Meanwhile, the stamping die 2 is provided with a discharge die on the side away from the positioning die 51. The discharge die can have the same structure as the positioning die 51, which facilitates the automatic feeding and discharging structure 4 to leave the stamped part.

[0034] Furthermore, the second limiting hole 52 is located on the side of the positioning mold 51 facing the automatic feeding and unloading structure 4. The second limiting hole 52 has the same structure as the first limiting hole 21. Both are adapted to the punched finished parts and the parts to be processed, which can further improve the positioning accuracy and lay a structural foundation for the smooth operation of the subsequent automatic feeding and unloading structure 4.

[0035] like Figure 2 The structure shown and the motion trajectory of each component are illustrated in this embodiment. The automatic feeding / unloading structure 4 includes a Y-axis moving component 43, an X-axis moving component 41, and a Z-axis moving component 42. The X-axis moving component 41 drives the Z-axis moving component to perform reciprocating motion in the X-axis direction; the Z-axis moving component 42 drives the Y-axis moving component 43 to perform reciprocating motion in the Z-axis direction. Through the three-axis drive of X, Y, and Z, the automated handling of workpieces is achieved, taking into account both the motion accuracy and operational stability of workpiece feeding and unloading, thereby improving production efficiency.

[0036] The X-axis moving assembly 41 includes a first guide rail 411, a first drive stage 412, and a first driver for driving the first drive stage to reciprocate in the X-axis direction. The first guide rail 411 is located on the ground, the first drive stage 412 is slidably connected to the first guide rail 411, and the output end of the first driver is detachably connected to the first drive stage by bolts.

[0037] Z-axis moving assembly 42 includes a second guide rail 421, a second drive stage 422, and a second driver for driving the second drive stage to reciprocate in the Z-axis direction. The second guide rail 421 is disposed on the first drive stage 412, and the second drive stage 422 is slidably connected to the second guide rail 421. The output end of the second driver is detachably connected to the second drive stage 422 by bolts.

[0038] The Y-axis moving assembly 43 includes a third guide rail 431, a third drive stage 432, and a third driver 433 for driving the third drive stage 432 to reciprocate in the Y-axis direction. The third guide rail 431 is located on the side of the second drive stage 422 away from the ground. The third drive stage 432 is slidably connected to the third guide rail 431. The output end of the third driver 433 is detachably connected to the third drive stage 432 by bolts. By adjusting the movement of each moving assembly in the X, Y, and Z axes, the normal operation of material feeding and discharging is ensured.

[0039] In this embodiment, the third drive platform 432 is provided with a feed block 442 and a discharge block 452 on the side facing the workbench 3, which provides an installation foundation for the subsequent structure.

[0040] The feed block 442 and the discharge block 452 are provided with a feed column 44, a discharge column 45, a workpiece clamping block 441, and a workpiece lifting block 451 on the side facing the worktable 3. The workpiece clamping block 441 is located on the side of the feed column 44 away from the ground and forms a workpiece clamping area with the feed column 44. The workpiece lifting block 451 is located on the side of the discharge column 45 facing the ground and forms a workpiece transport area with the discharge column 45.

[0041] Since the third drive stage 432 is located at the output end of the third driver 433, it can drive the feed column 44, the discharge column 45, the workpiece clamping block 441, and the workpiece lifting block 451 to reciprocate in the Y-axis direction, thereby achieving the technical effect of workpiece clamping. At the same time, it can drive the feed column 44, the discharge column 45, the workpiece clamping block 441, and the workpiece lifting block 451 to move synchronously, so that they can complete each process synchronously, improving the production efficiency and structural compactness of this embodiment.

[0042] When the discharge column 45 is pushed forward by the third drive table 432, the workpiece lifting block 451 inserts into the gap between the first limiting hole 21 and the lower part of the punched part, and abuts against the punched part; at the same time, the workpiece clamping block 441 reaches directly above the workpiece to be processed and abuts against the workpiece to be processed. Then, when the feed column 44 and the discharge column 45 are lifted by the second drive table 422, the workpiece lifting block 451 and the workpiece clamping block 441 can keep the opening position of each workpiece unchanged, and proceed to the next process.

[0043] The distance between the feed column 44 and the discharge column 45 is equal to the distance between the positioning mold 51 and the stamping mold 2, and between the stamping mold 2 and the discharge mold. It can be adjusted according to the actual distance between the positioning mold 51 and the stamping mold 2, and between the stamping mold 2 and the discharge mold. This embodiment will not elaborate further.

[0044] like Figure 4 As shown, in this embodiment, quick-connect fixing heads 7 are provided at the connection points between the discharge column 45, the feed column 44 and the discharge block 452, and the feed block 442. Compared with traditional fixing methods such as bolt fastening and welding, the quick-connect fixing heads 7 eliminate complex disassembly and assembly steps, shortening downtime. At the same time, the quick-connect structure can form a tight connection through mechanisms such as snap-fit ​​and locking, reducing the possibility of loosening or displacement of the discharge column 45 and the feed column 44 due to force when transferring workpieces, thus ensuring the stability of this embodiment. Furthermore, the quick-connect fixing heads 7 are detachably connected to the feed block 442 and the discharge block 452 via bolts, balancing connection stability and convenience, facilitating replacement and maintenance by maintenance personnel.

[0045] like Figure 6As shown, in this embodiment, the workbench 3 facing the stamping die 2 is provided with a scrap discharge structure 6, which includes a scrap discharge plate 61 and a scrap discharge plate support column 62. The scrap discharge plate support column 62 is located on the side of the workbench 3 away from the ground. One end of the scrap discharge plate 61 is located on the side of the scrap discharge plate support column 62 away from the ground, and the other end is located on the side of the workbench 3 away from the scrap discharge plate support column 62. The scrap discharge plate 61 is provided with a scrap guide ramp 63 on the side away from the ground, which can receive the scrap generated after punching and slide the scrap through the scrap guide ramp 63 to the scrap collection box or scrap conveyor and other recycling structures below.

[0046] In this embodiment, the waste discharge plate 61 is provided with a discharge plate mounting groove 64 on the side facing the stamping die 2. The waste discharge plate 61 is sleeved on the outside of the stamping die 2 through the discharge plate mounting groove 64, which not only improves the overall integrity and structural compactness of the equipment, but also enables comprehensive collection of waste.

[0047] The specific workflow of this embodiment is as follows:

[0048] 1. The workpiece to be processed is conveyed by the conveyor belt and enters the positioning mold 51 from the positioning inlet 54. The limiting groove 53 of the positioning mold 51 abuts to complete the initial positioning. At the same time, the through hole protrusion of the edge of the workpiece to be processed enters the second limiting hole 52. At this time, the positioning of the workpiece to be processed is completed.

[0049] 2. After the workpiece located at the stamping die 2 is punched (the workpiece will appear on the stamping die 2 after the first round of work is completed), the first drive table 412 moves along the X-axis towards the positioning die 51 through the drive of the first driver.

[0050] 3. When the ejector column 45 and the feed column 44 move to the first limiting hole 21 of the corresponding stamping die 2 and the second limiting hole 52 of the positioning die 51, the third drive table 432 is driven by the third driver 433 and moves along the Y-axis towards the positioning die 51 and the stamping die 2, so that the ejector column 45 is accurately inserted into the through holes at both ends of the punched part through the first limiting hole 21, and the feed column 44 is accurately inserted into the through holes at both ends of the workpiece through the second limiting hole 52.

[0051] 4. As the ejector pin 45 is inserted into the through hole of the punched part on the stamping die 2, the workpiece lifting block 451 is also inserted into the gap between the bottom of the workpiece and the first limiting hole 21 and abuts against the bottom of the punched part. At the same time, the feed pin 44 is inserted into the through hole of the workpiece to be processed, and the workpiece clamping block 441 abuts against the top of the workpiece to be processed.

[0052] 5. After the discharge column 45 and the feed column 44 have completely penetrated each workpiece, the second drive stage 422 is driven by the second driver and lifted along the Z-axis under the limit of the second guide rail 421, so that the two workpieces are completely separated from their respective molds. Then the first drive stage 412 moves along the X-axis away from the positioning mold 51, driving the workpieces to their respective next process positions.

[0053] 6. When the feed column 44 reaches the top of the stamping die 2, the second drive table 422 descends along the second guide rail 421, so that the workpiece to be processed is accurately placed in the stamping die 2 (the edge is embedded in the first limiting hole 21) and waits for punching.

[0054] The punched part is then placed in the discharge mold by the discharge column 45.

[0055] 7. After stamping is completed, the processing waste falls onto the inclined waste discharge plate 61 under its own weight, and slides down the waste guide slope 63 into the waste recycling structure below.

[0056] 8. After the workpiece is completely placed and stabilized, the third driver 433 drives the third drive stage 432 to reset along the Y-axis. After the feed column 44 and the discharge column 45 are separated from the workpieces, the first drive stage 412 moves and resets along the X-axis towards the positioning mold 51. At this time, one automatic feeding and discharging cycle is completed.
