Description

Technical Field

[0001] This utility model relates to the technical field of metal parts stamping devices, specifically a metal parts stamping device. Background Technology

[0002] A metal parts stamping device is a processing equipment that uses pressure to drive a die to plastically form or separate sheet metal. Its core components include a press, upper die, lower die, and a feeding system. During operation, the sheet metal is placed between the upper and lower dies. The press slide drives the upper die downwards, and the enormous impact force causes the material to undergo deformations such as shearing, bending, stretching, or extrusion within the die cavity, thus efficiently obtaining parts of the desired shape and size in a single operation. This device is widely used in the automotive, electronics, and home appliance industries and is suitable for high-volume, high-precision, rapid production.

[0003] The application document with publication number "CN 220112056 U" mentions that "parts will stick to the upper mold and need to be manually knocked off." The device knocks the parts with a knocking post, thereby saving labor. However, since the stuck parts are mostly thin parts, the knocking method can easily lead to excessive force and damage to the surface of the workpiece, affecting product quality. Moreover, there may be metal particles left on the surface of the workpiece during the stamping process. If they are not cleaned, the smoothness of the product can be reduced. Utility Model Content

[0004] The purpose of this invention is to provide a metal parts stamping device to solve the problems mentioned in the background art.

[0007] Preferably, the cylinder has an internal air supply port.

[0008] Preferably, the slide bar is configured as a square structure.

[0009] Preferably, the upper side of the pry bar has a beveled cut.

[0013] Compared with the prior art, this utility model provides a metal parts stamping device, which has the following features:

[0014] Beneficial effects:

[0015] 1. The part removal mechanism is used to remove workpieces that may be stuck in the upper mold. The mechanism uses a spring and a pry bar to approach the workpiece and uses the inclined surface of the pry bar to hook the edge of the workpiece. Then, the pry bar is driven down by a cylinder to easily remove the workpiece. At the same time, the screw in the mechanism allows for easy adjustment of the position of the pry bar to adapt to upper molds of different sizes and reduce the impact of space occupation. This makes the structure of the device simple and the demolding safety high.

[0016] 2. The chip removal mechanism is used to clean impurities on the surface of the lower die. This mechanism, through the cooperation of the positioning plate and the insertion plate, allows the drawer to be adjusted to the upper side of the lower die when needed. This facilitates the removal of impurities from the surface of the lower die or reduces the space occupied, effectively preventing metal particles from being pressed into the workpiece, thereby improving product quality.

[0028] This mechanism is used to remove thin parts stuck inside the upper mold 4. This mechanism improves the flexibility of the device and the safety of demolding. The demolding mechanism 6 includes a slider 601, which is slidably connected inside the slide table 2. A screw 602 is rotatably connected inside the slide table 2. The outer wall of the screw 602 is threadedly connected to the slider 601. A cylinder 603 is fixedly connected to the lower surface of the slider 601. A piston plate 604 is slidably connected inside the cylinder 603. A slide rod 605 is fixedly connected to the lower surface of the piston plate 604. A slide cylinder 606 is fixedly connected to the lower surface of the slide rod 605. A spring 607 is fixedly connected inside the slide cylinder 606. A push block 608 is fixedly connected to the end of the spring 607 near the upper mold 4. The push block 608 is slidably connected inside the slide cylinder 606. A pry block 609 is fixedly connected to the side of the push block 608 away from the spring 607. The pry block 609 is slidably connected inside the slide cylinder 606.

[0029] Furthermore, an air supply port is provided inside the cylinder 603.

[0030] Furthermore, the slide bar 605 is designed with a square structure.

[0031] Furthermore, the upper side of the pry bar 609 has a beveled cut.

[0032] Example 2:

[0033] This mechanism is used to clean debris from inside the lower mold 5, improving the cleaning effect of the lower mold 5. Please refer to [link / reference needed]. Figure 1-5Furthermore, in conjunction with Embodiment 1, the chip removal mechanism 7 includes a piston cylinder 701, which is fixedly connected inside the base 1. A piston rod 702 is slidably connected inside the piston cylinder 701. A slide 703 is fixedly connected to one end of the piston rod 702. The slide 703 is slidably connected inside the base 1. An air cylinder 704 is fixedly connected to the upper side of the slide 703. A motor 705 is fixedly connected inside the air cylinder 704. A fan blade 706 is fixedly connected to the output end of the motor 705. The fan blade 706 is disposed inside the air cylinder 704. A filter plate 707 is fixedly connected to the upper part of the air cylinder 704. The filter plate 707 is set on the upper side of the fan blade 706. A positioning plate 708 is fixedly connected to the upper surface of the air cylinder 704. A drawer 709 is rotatably connected to the upper side of the positioning plate 708. The drawer 709 is connected to the negative pressure end of the fan blade 706 inside the air cylinder 704. A plug plate 710 is fixedly connected to one side of the drawer 709. A plug rod is provided between the plug plate 710 and the positioning plate 708. A hydraulic connector is provided inside the piston cylinder 701. The user can connect a motor 705 to the screw 602 to control the rotation of the screw 602.

[0034] Furthermore, the insertion plate 710 and the positioning plate 708 are evenly provided with holes of the same diameter inside.

[0035] Furthermore, the drawer 709 has an inverted convex-shaped slot inside.

[0036] In actual operation, when this device is used, if a workpiece is stuck inside the upper die 4 after the stamping work is completed, the user can supply air pressure into the cylinder 603. At this time, the pry bar 609 is in contact with the surface of the upper die 4 and the spring 607 is in a compressed state. The air pressure pushes the piston plate 604 downward, causing the slide cylinder 606 to be driven, which in turn causes the pry bar 609 to be driven downward synchronously. After the pry bar 609 contacts the gap between the workpiece and the upper die 4 at an angle, with the continuous output of the cylinder 603, the pry bar 609 can drive the workpiece downward through the lower horizontal surface until the workpiece is disengaged from the upper die 4. After the upper die 4 is replaced, the user can adjust the position of the slider 601 by rotating the screw 602, or if there is insufficient space around the lower die 5, the user can move the slider 601 to the outside of the slide table 2. After the workpiece is removed, the user can collect the workpiece. Before the next stamping operation begins, the user can adjust the position of the drawer 709 by inserting the plate 710 and when the piston cylinder 701 outputs hydraulic pressure, the drawer 709 slides around the upper surface of the lower die 5 to the other side of the upper die 4, so that the negative pressure generated by the fan blade 706 can directly extract the debris inside the lower die 5, thereby improving the stamping quality.
