Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fireworks processing, in particular to a fireworks tube punching device for fireworks processing. Background Art
[0002] During the processing of fireworks, in order to connect the fuse inside the firework tube, the other end of the fuse needs to be exposed, and then each firework tube needs to be punched. The staff usually uses a perforating gun to puncture and punch holes in the firework tube for subsequent processing. Since a batch of firework tubes needs to be punched in multiple places, and the perforating gun needs to be bolted after each punching, the current punching device is not convenient for automatically resetting after each punching when punching the firework tube, which makes it inconvenient for the staff to use it next time, resulting in low punching efficiency. In addition, the existing punching device is not convenient for pressing against the inner wall of the firework tube while punching, which makes the punched holes not smooth, thereby reducing the punching effect. Utility Model Content
[0003] In order to overcome the above shortcomings, the utility model provides a firework tube punching device for fireworks processing, which can automatically reset after each punching, thereby improving the punching efficiency and making the punched holes smoother, thereby improving the punching effect.
[0004] The technical solution is: a fireworks tube punching device for fireworks processing, comprising an outer frame, a protective sleeve fixedly connected to one side of the outer frame, the protective sleeve is communicated with the outer frame, a hand pull rod is rotatably connected to the outer frame, a torsion spring is connected between the hand pull rod and the outer frame, a sliding frame is slidably connected to one side of the outer frame, the sliding frame is slidably connected to the hand pull rod, an extrusion rod is fixedly connected to one end of the sliding frame, a sliding rod is slidably connected to the outer frame, the sliding rod is slidably connected to the extrusion rod, and the A compression spring 1 is connected between the sliding rod and the extrusion rod, a piercing needle is fixedly connected to one end of the sliding rod away from the extrusion rod, a clamping block is slidably connected to the outer frame, the clamping block contacts the sliding rod, a compression spring 2 is connected between the clamping block and the outer frame, an extrusion block is fixedly connected to the hand rod, and a resisting assembly is provided on the outer frame, the resisting assembly will resist the inner wall of the firework tube and make the outer wall of the firework tube close to the protective cover, thereby making the subsequent punching smoother, thereby improving the punching effect.
[0005] Furthermore, the surface of the piercing needle is coated with lubricating liquid.
[0006] Furthermore, the protective cover is made of rubber.
[0007] Furthermore, the resisting assembly includes a limiting plate, which is fixedly connected to the outer frame, a stopper is slidably connected to the limiting frame, a round hole is opened on the stopper, and a compression spring three is connected between the stopper and the limiting plate.
[0008] Furthermore, the stopper is made of anti-slip material.
[0009] Compared with the prior art, the utility model has the following advantages: 1. The staff rotates the hand lever by pulling the hand lever, and the rotation of the hand lever will cause the extrusion rod to squeeze the sliding rod through the compression spring 1. At the same time, the hand lever will drive the card block to move downward through the extrusion block and disengage from the sliding rod. The compression spring 1 quickly resets to allow the perforating needle to punch holes in the firework tube. After the punching is completed, the staff removes their fingers from the hand lever, and the resetting of the torsion spring will drive the hand lever to reset. The resetting of the hand lever will reset the perforating needle through the sliding frame. At the same time, the resetting of the extrusion block will reset the card block. The resetting of the sliding rod will first squeeze the card block, and then the sliding rod continues to move and no longer squeezes the card block. The resetting of the compression spring 2 will drive the card block to reset and contact the sliding rod, and repeat this process. Each time the staff pulls the hand lever, the perforating needle will automatically reset, which is convenient for the next use, thereby improving the punching efficiency.
[0010] 2. When the staff places the firework tube, under the action of compression spring three, the block will squeeze the side wall of the firework tube into close contact with the protective cover. At the same time, the block will press against the inner wall of the firework tube, making the subsequent punching smoother, thereby improving the punching effect. BRIEF DESCRIPTION OF THE DRAWINGS
