Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for the production of automotive parts that avoids the accumulation of waste. Background Technology

[0002] Stamping die equipment is a special process equipment used in cold stamping to process metal or non-metal into parts or semi-finished products. It is called cold stamping die or cold stamping mold. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the required parts. Automotive parts can be produced by stamping using stamping dies.

[0003] In existing automotive parts stamping dies, some scrap material tends to remain inside the die during stamping. This scrap material usually requires manual cleaning by workers using an air gun, causing inconvenience in the automotive parts stamping process. To address this, we propose a stamping die for automotive parts production that avoids scrap accumulation. Utility Model Content

[0004] The main objective of this invention is to provide a stamping die for automotive parts production that avoids waste accumulation. By setting a side notch and a chip blowing mechanism in the stamping die, the chip blowing mechanism uses a cylinder to drive the chip filling block to blow out gas to automatically remove waste from the stamping bottom die, thus preventing waste from accumulating inside the stamping bottom die. The chip filling block has air blowing holes distributed on three sides, and with the internal cavity partition structure, high-pressure gas can be directionally sprayed to quickly remove waste, making the stamping and waste removal processes seamlessly connected, significantly improving the automation level and production efficiency of the production line, and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stamping die for automotive parts production that avoids waste accumulation includes a stamping base die and a chip blowing mechanism. The chip blowing mechanism includes a missing block, a rubber plug, a plugging plate, a connecting seat, a cylinder, a side mounting plate, and a bent pipe. The stamping base die has a side notch groove on its surface, and a missing block is fitted inside the side notch groove. The missing block has an internal cavity on its back surface away from the stamping base die, and air blowing holes are arranged on the U-shaped block surface of the missing block facing the stamping base die. A rubber plug is fitted inside the internal cavity, and a plugging plate is bolted to the missing block below the side cavity opening of the internal cavity to block the internal cavity. A connecting seat is welded to the center of the outer plate of the plugging plate, and a telescopic rod head of a cylinder is screwed into the connecting seat. The cylinder is locked to the surface of the stamping base die by the side mounting plate. A bent pipe is welded to the surface of the plugging plate outside the connecting seat. An air hole is formed on the block of the rubber plug near the bent pipe.

[0007] Furthermore, the upper blocking plate of the blocking plate is engaged with the cavity opening of the inner connecting cavity, and the vertical plate of the blocking plate and the filling block are provided with mounting holes for screwing bolts.

[0008] By adopting the above technical solution, after the upper blocking plate of the plugging plate can block the opening of the inner cavity, its vertical plate can be locked at the filling block with bolts to obtain support.

[0009] Furthermore, the outer surface of the upper block plate of the plugging plate is welded with a seat plate of the connecting seat, and a threaded cylinder for screwing the telescopic rod head on one side of the cylinder is fixed on the surface of the seat plate of the connecting seat.

[0010] By adopting the above technical solution, after the upper plug plate of the plug plate is welded to the seat plate of the connecting seat, the threaded cylinder of the connecting seat can be screwed to the telescopic rod head of the cylinder for connection, so that the cylinder can drive the plug plate to move linearly with the filling block.

[0011] Furthermore, the two sides of the filling block near the side notch are symmetrically provided with air blowing holes, and the filling block is provided with air blowing holes arranged on the long side of the stamping bottom die.

[0012] By adopting the above technical solution, a large number of air blowing holes are set on the three sides of the filling block to blow away the waste debris in the inner cavity of the stamping bottom mold.

[0013] Furthermore, the cavity of the inner connecting cavity is fixed with partition ribs for separating the cavity, and the cavity between the partition ribs is interconnected with the air blowing hole, and the surface of the plugging plate outside the cavity is welded with a bent pipe.

[0014] By adopting the above technical solution, after the inner cavity is separated into a partition by a rib, a narrow cavity exists at the air inlet position of the air blow hole. This allows the equipment pipeline that provides compressed gas to be connected by a bend pipe and a hose, ensuring that compressed gas with high efficiency in blowing debris can be blown out at each air blow hole.

[0015] Furthermore, mounting holes for screwing bolts are provided between the cylinder body of the cylinder and the vertical plate of the side mounting plate, and mounting holes for screwing bolts are provided between the bottom plate of the side mounting plate and the stamping bottom die.

[0016] By adopting the above technical solution, after the vertical plate of the side mounting plate is locked to the cylinder with bolts, the bottom plate of the side mounting plate can be locked to the surface of the stamping die with bolts to obtain support.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model sets a side notch and a chip blowing mechanism in the stamping die used in the production of automotive parts. The chip blowing mechanism uses a cylinder to drive the chip blowing block to blow out gas to automatically remove the waste in the stamping bottom die, avoiding the accumulation of waste in the stamping bottom die. The chip blowing block has air blowing holes distributed on three sides, and with the internal cavity partition structure, high-pressure gas can be sprayed in a directional manner to quickly remove waste, so that the stamping and waste removal processes are seamlessly connected, significantly improving the automation level and production efficiency of the production line.

[0019] Furthermore, the gap-filling block is separated into an independent cavity by a partition rib. At the same time, each cavity of the gap-filling block is individually connected to a compressed air source by a bent pipe, so that the air blowing hole of the gap-filling block can obtain compressed gas with sufficient pressure through the cavity, thereby providing a stable chip-removing force.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-5As shown, a stamping die for automotive parts production that avoids waste accumulation includes a stamping base die 1 and a chip blowing mechanism 3. The chip blowing mechanism 3 includes a filling block 4, a rubber plug 8, a plugging plate 9, a connecting seat 10, a cylinder 11, a side mounting plate 12, and a bent pipe 13. A side notch groove 2 is formed on the surface of the stamping base die 1, and the filling block 4 is fitted into the side notch groove 2. An internal connecting cavity 5 is formed on the back block surface of the filling block 4 away from the stamping base die 1, and the filling blocks 4 are arranged facing the U-shaped block surface inside the stamping base die 1. An air blowing hole 7 is provided. A rubber plug 8 is installed inside the inner cavity 5. A plugging plate 9 is bolted to the filling block 4 below the side cavity opening of the inner cavity 5 to block the inner cavity 5. A connecting seat 10 is welded to the center of the outer plate surface of the plugging plate 9. The telescopic rod head of the cylinder 11 is screwed into the connecting seat 10. The cylinder 11 is locked to the surface of the stamping bottom mold 1 by the side mounting plate 12. A bent pipe 13 is welded to the surface of the plugging plate 9 outside the connecting seat 10. An air hole is opened in the block of the rubber plug 8 near the bent pipe 13.

[0028] The upper blocking plate of the blocking plate 9 is engaged with the cavity opening of the inner connecting cavity 5, and the vertical plate of the blocking plate 9 and the filling block 4 are provided with mounting holes for screwing bolts.

[0029] By adopting the above technical solution, after the upper blocking plate of the blocking plate 9 can block the cavity opening of the inner connecting cavity 5, its vertical plate body can be locked at the filling block 4 with bolts to obtain support.

[0030] The upper end plate of the plugging plate 9 is welded with a seat plate of the connecting seat 10, and a threaded cylinder for screwing the telescopic rod head on one side of the cylinder 11 is fixed on the surface of the seat plate of the connecting seat 10.

[0031] By adopting the above technical solution, after the upper blocking plate of the blocking plate 9 is welded to the seat plate of the connecting seat 10, the threaded cylinder of the connecting seat 10 can be connected to the telescopic rod head of the cylinder 11, so that the cylinder 11 can drive the blocking plate 9 to move linearly with the filling block 4.

[0032] Among them, the two sides of the missing block 4 near the side missing groove 2 are symmetrically provided with air blowing holes 7, and the missing block 4 is provided with air blowing holes 7 facing the long block surface of the stamping bottom mold 1.

[0033] By adopting the above technical solution, a number of air blowing holes 7 are set on the three sides of the filling block 4 to blow away the waste chips in the inner cavity of the stamping bottom mold 1.

[0034] The inner cavity 5 is provided with fixed partition ribs 6 for separating the cavity, and the cavity between the partition ribs 6 is interconnected with the air blowing hole 7, and the surface of the plug plate 9 outside the cavity is welded with a bent pipe 13.

[0035] By adopting the above technical solution, after the inner cavity 5 is separated into a partition cavity by the partition 6, a narrow cavity exists at the air inlet position of the air blow hole 7. Thus, the equipment pipeline that provides compressed gas can be connected by the elbow pipe 13 and the hose, ensuring that each air blow hole 7 can blow out compressed gas with high efficiency in blowing debris.

[0036] The cylinder body of the cylinder 11 and the vertical plate of the side mounting plate 12 are provided with mounting holes for screwing bolts, and the bottom plate of the side mounting plate 12 and the stamping bottom die 1 are provided with mounting holes for screwing bolts.

[0037] By adopting the above technical solution, after the vertical plate of the side mounting plate 12 is locked to the cylinder 11 with bolts, the bottom plate of the side mounting plate 12 can be locked to the surface of the stamping bottom mold 1 with bolts to obtain support.

[0038] It should be noted that this utility model is a stamping die for automobile parts production that avoids waste accumulation. A side notch 2 and a chip blowing mechanism 3 are provided in the stamping die for automobile parts production. After the chip blowing mechanism 3's filling block 4 is installed in the side notch 2, a rubber plug 8 can be installed in the inner cavity 5 of the filling block 4 for sealing. Then, a plugging plate 9 is installed in the inner cavity 5, and the plugging plate 9 can be locked to the filling block 4 with bolts. The plugging plate 9 is then screwed to the telescopic rod head of the cylinder 11 via a connecting seat 10. Simultaneously, after the vertical plate of the side mounting plate 12 is locked to the cylinder 11 with bolts, the bottom plate of the side mounting plate 12 can be locked to the surface of the stamping die 1 with bolts for support. Finally, the bent pipe 13 of the plugging plate 9 can be used with a flexible hose, and can be operated by a professional technician based on their experience. Next, connect the equipment pipeline that provides compressed gas. A solenoid valve for pneumatic control can be installed at the hose for on-demand control. The hose needs to have sufficient allowable length to ensure that the filling block 4 is not overly stretched when it enters the stamping die 1. The cylinder 11, connected to an external controllable air source, can extend and retract as needed. When a car part is placed between the stamping die 1 and the upper stamping die for automotive parts, the filling block 4 can be inserted into the side notch 2 to complete the die cavity structure, allowing the car part to be stamped normally. After the stamped car part is removed, the cylinder 11 can push the filling block 4 into the stamping die 1 and then retract to reset. Compressed gas can then be blown out from the air blowhole 7 at the filling block 4, thus preventing waste material from accumulating in the stamping die 1. The filling block 4 can be adjusted according to… Figure 3 A rectangular groove is set in the middle, and a rectangular block can be reserved in the groove of the side notch 2 for positioning and connection.
