Description

Technical Field

[0001] This utility model belongs to the field of pyrotechnics production technology, specifically relating to an outer cylinder orifice shaping device. Background Technology

[0002] In the field of shaping the outer tube openings of fireworks and other pyrotechnic products, traditional processing methods mainly rely on manual labor or simple machinery. Manual operation relies on experience for shaping, while simple machinery serves as basic auxiliary tools, both of which have significant shortcomings. With technological advancements, automated punching and cutting equipment has emerged, improving production efficiency to some extent. However, the industry's increasingly stringent requirements for product quality have made the need for high-precision shaping equipment ever more urgent.

[0003] Existing technologies suffer from several core problems. First, processing accuracy is low, with unstable tolerances in the outer cylinder orifice dimensions, making it difficult to meet the demands of high-precision production. This is mainly due to the limitations of manual operation, which struggles to precisely control force and position; and the complexity of automated equipment, which is prone to deviations during operation. Second, production efficiency is low. Manual operation is slow, and automated equipment changeover is time-consuming, limiting overall production capacity. Manual operation is limited by physical strength and skill, while equipment changeover requires parameter adjustments and tooling replacements, a cumbersome process. Third, there are significant safety hazards. Manual operation involves direct contact with hazardous areas, and automated equipment cannot completely eliminate the risk of personnel approaching such areas. Finally, the equipment has poor adaptability, struggling to effectively shape outer cylinders of different specifications and materials. Existing equipment designs are mostly geared towards specific specifications and materials, lacking sufficient material adaptability and unable to flexibly meet diverse production needs.

[0004] Therefore, this utility model provides an outer cylinder orifice shaping device to solve many problems existing in the current outer cylinder orifice shaping technology. Utility Model Content

There are 4 guide rods 12, which are located at the four corners of the slot plate 16 to ensure the verticality and stability of the slot plate 16 when it moves up and down.

[0030] In the practical application of this embodiment, the shaping fixture 15 is detachably installed below the slot plate 16 by the locking screw 17, and different specifications of shaping fixtures can be easily replaced by tightening or loosening the inner locking screw 17.

[0031] In the practical application of this embodiment, the tooling pallet 2 includes an outer cylinder 21, a limiting pallet 22, and a tooling plate 23. The tooling plate 23 has a plurality of pin holes. The outer cylinder 21 is vertically arranged above the limiting pallet 22.

[0032] In the practical application of this embodiment, the bottom of the shaping fixture 15 is provided with a plurality of shaping holes, the size and position of which match the opening of the outer cylinder 21 and the shaping fixture 15.

[0033] In the practical application of this embodiment, the conveying lifting line 3 includes a conveying line 31, a blocking mechanism 32, and a lifting mechanism 33. The conveying line 31 is disposed in the frame 4 and is used to convey the tooling pallet 2. The blocking mechanism 32 is disposed on one side of the conveying line 31 and is used to block the movement of the tooling pallet 2 and to achieve positioning. The lifting mechanism 33 is disposed below the conveying lifting line 3 and cooperates with the blocking mechanism 32. When the tooling pallet 2 is blocked and positioned, the lifting mechanism 33 lifts the tooling pallet 2 to the working position of the pressing and shaping mechanism 1.

[0034] In the practical application of this embodiment, the blocking mechanism 32 includes a blocking cylinder and a blocking block. The blocking cylinder is fixed on a bracket on one side of the conveying lifting line 3. The piston rod of the blocking cylinder is connected to the blocking block, and the blocking block is driven to extend or retract by the blocking cylinder.

[0035] In the practical application of this embodiment, the lifting mechanism 33 includes a lifting cylinder and a lifting plate. The lifting cylinder is fixed below the conveying lifting line 3. The piston rod of the lifting cylinder is connected to the lifting plate. The lifting plate is provided with a support block corresponding to the bottom of the tooling pallet 2, which is used to smoothly lift the tooling pallet 2.

[0036] The assembly process in this embodiment is as follows:

[0037] First, install the frame structure of the mounting frame 4 by welding high-strength steel into a sturdy frame. Install anchor bolts at the bottom and adjust them to ensure the frame is level, with the levelness deviation controlled within ±0.1mm. Next, fix the mounting plate 13 to the top of the frame structure using bolts, ensuring the mounting plate is securely installed and the bolt tightening torque meets the specified value.

[0038] Then, install the pressing and shaping mechanism 1, and fix the cylinder 11 on the mounting plate 13 at the top of the frame 4, ensuring that the cylinder 11 is installed in an accurate position with a verticality tolerance of ≤0.1mm. Connect the push rod to the piston rod of the cylinder 11, ensuring a tight connection without any looseness. Vertically fix the four guide rods 12 to the mounting plate 13, with a vertical tolerance of ≤0.1mm. Then, slide the groove plate 16 to the guide rods 12, ensuring that the groove plate 16 can move smoothly up and down. Finally, install the shaping fixture 15 under the groove plate 16 using the locking screws 17 (hex socket head cap screws).

[0039] For assembling the tooling pallet 2, first place the limiting pallet 22 in a suitable position, and then use pins and pin holes to position and install the tooling plate 23 and the limiting pallet 22. The pin hole fitting accuracy needs to be controlled within ±0.02mm.

[0040] For the conveyor lifting line 3, first install the conveyor line 31 in the frame 4 to ensure smooth operation. Fix the blocking cylinder of the blocking mechanism 32 to the bracket on one side of the conveyor line, and connect the blocking block to the piston rod of the blocking cylinder to ensure flexible and accurate blocking action. Fix the lifting cylinder of the lifting mechanism 33 below the conveyor line, connect the lifting plate to the piston rod of the lifting cylinder, and align the support block on the lifting plate with the bottom of the tooling pallet to ensure stable lifting of the tooling pallet.

[0041] The workflow of this embodiment is as follows:

[0042] First, the conveyor line 31 begins transporting the tooling pallet 2, which carries the outer cylinder 21 to be shaped, forward along the conveyor line 31. When the tooling pallet 2 reaches the designated position, the blocking mechanism 32 is activated, and the blocking cylinder drives the blocking block to extend, blocking the movement of the tooling pallet 2 and achieving the positioning of the tooling pallet 2.

[0043] Next, the lifting mechanism 33 starts working, and the lifting cylinder drives the lifting plate to rise. The support block on the lifting plate contacts the bottom of the tooling tray 2, smoothly lifting the tooling tray 2 to the working position of the pressing and shaping mechanism 1. At this time, the cylinder 11 of the pressing and shaping mechanism 1 starts, the piston rod pushes the push rod, and the push rod drives the slot plate 16 and the shaping tooling 15 to move downward, performing a shaping operation on the orifice of the outer cylinder 21 in the tooling tray 2.

[0044] After shaping, cylinder 11 drives the push rod to raise the slot plate and shaping fixture 15 back to their initial position. The lifting cylinder of the lifting mechanism 33 drives the lifting plate to descend, and the fixture pallet 2 returns to the conveyor line 31. Then, the blocking cylinder of the blocking mechanism drives the blocking block to retract, and the conveyor line 31 continues to run, transporting the shaped fixture pallet 2 to the subsequent workstation.

[0045] When it is necessary to change to a different specification of outer cylinder 21 for shaping, the locking screw 17 of the shaping fixture can be loosened, a suitable shaping fixture can be replaced, and the locking screw 17 can be tightened again to continue production. The product changeover operation is simple and quick, which can effectively improve production efficiency.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
