Description

Technical Field

[0001] This utility model relates to the field of composite plate processing technology, specifically to an explosion welding protection device for copper-steel composite plates. Background Technology

[0002] Copper-steel composite plates are a new type of material made by welding copper and steel plates together through methods such as explosive bonding and explosive rolling. These plates are inseparable and possess both the corrosion resistance and wear resistance of precious metals and the good weldability, formability, ductility, and thermal conductivity of carbon steel. Because explosive welding generates a large amount of dust, protective devices are required during the process.

[0003] Chinese Utility Model Announcement No. CN220498048U includes: a welding platform, the top of which is equipped with a dust suppression mechanism. This dust suppression mechanism is used for protection during explosive welding and to purify harmful fumes generated during the welding process. The dust suppression mechanism also includes a filter mechanism for filtering dust and impurities generated during explosive welding. Through the arrangement of the dust suppression and filter mechanisms, during explosive welding, the dust suppression frame covers the top of the welding platform, protecting it from the explosion while preventing the spread of dust and fumes. The dust collection trough then draws the fumes into the dust collection box for further purification, preventing air pollution. Before entering the dust collection trough, the dust passes through a filter plate, which filters the dust, reducing air pollution. When the filter plate needs cleaning or replacement, simply turn the handle and unscrew the bolts to remove it; the operation is convenient.

[0004] The applicant discovered some shortcomings in the use of the patent: when removing the filter plate, the worker's entire body needs to be directly below the dust collection frame to tighten the bolts. If the dust collection frame suddenly drops, it is quite dangerous. At the same time, the inside of the dust collection frame is dark, which increases the difficulty of disassembling the filter plate. Moreover, it is not convenient to tighten the four bolts one by one.

[0005] Therefore, this utility model designs an explosion protection device for copper-steel composite plates to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device for explosive welding of copper-steel composite plates, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective device for explosive welding of copper-steel composite plates, comprising: a welding platform, a protective box above the welding platform, a dust suction pipe connected to the top of the protective box, a fixed ring fixedly installed on the upper inner wall of the protective box, a limiting ring installed on the upper inner wall of the fixed ring, a filter plate at the bottom of the limiting ring, a movable ring at the bottom of the filter plate, an internal thread on the lower inner wall of the fixed ring, an external thread on the outer outer wall of the movable ring, connecting blocks on both sides of the protective box, a lifting assembly for adjusting the height of the connecting blocks on the welding platform, and a flipping assembly for rotating the protective box on the connecting blocks.

[0008] Preferably, a dust suction hood is installed at the bottom of the suction pipe, and the dust suction hood is located above the fixing ring, which allows the suction pipe to suction dust better.

[0009] Preferably, a handle is installed at the bottom of the movable ring, which makes it convenient for the operator to rotate the movable ring.

[0010] Preferably, the lifting assembly includes two vertical frames, which are respectively installed on the top two sides of the welding platform. A lead screw is rotatably installed between the upper and lower ends of the vertical frames. The outer wall of the lead screw and one side of the connecting block are slidably installed by threads. The top of the lead screw is connected to the output end of a servo motor. A controller is installed on one of the vertical frames. The controller can make the two servo motors rotate synchronously, and make the two lead screws rotate synchronously, so that the two connecting blocks can be raised and lowered synchronously.

[0011] Preferably, the flipping component includes a through groove, which is formed on the connecting block. A drive motor is installed in the through groove, and the output end of the drive motor is connected to a rotating shaft. The two rotating shafts are respectively fixedly installed on the two outer side walls of the protective box. The controller can make the two drive motors rotate synchronously, and the synchronous rotation of the rotating shafts can drive the protective box to rotate. After the protective box rotates 90 degrees to face the operator, the operator can put their hand into the protective box to disassemble and install the filter plate, which is safer, increases brightness, and is more convenient to operate.

[0012] Preferably, the welding platform has an annular groove at the top center for insertion into the protective box, and the bottom of the protective box is inserted into the annular groove, which can improve the sealing between the welding platform and the protective box and reduce dust from escaping from the protective box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of the flipping component, drives the motor to rotate 90 degrees, so that the protective box rotates 90 degrees and the bottom of the protective box faces the worker. The worker does not need to stand directly under the protective box, but only needs to put his hand into the protective box, which is safer and also increases the two ends of the protective box, making it easier to operate.

[0015] 2. With the addition of external and internal threads, this utility model allows for the assembly and disassembly of the fixed and movable rings simply by rotating the movable ring. Compared to the method of tightening four bolts one by one, this makes it much easier to assemble and disassemble the filter plate, thus improving the efficiency of assembly and disassembly.

[0027] Please see Figure 1-3 In this embodiment: a circular groove 15 is provided at the top center of the welding platform 1 to be inserted into the protective box 2.

[0028] Working principle: Copper and steel plates are explosively welded at the top center of welding platform 1. The protective box 2 is inserted into the annular groove 15 to protect against the dust generated by the explosive welding, causing the dust to accumulate. The suction pipe 3 is connected to the air pump, creating negative pressure in the suction hood 4 to suck away the dust. When the dust passes through the filter plate 7, the filter plate 7 adsorbs the impurities in the dust. After the dust is sucked up, the lead screw 132 drives the connecting block 12 to rise, causing the protective box 2 to rise, and the copper-steel composite plate can be removed. When the filter plate 7 needs to be replaced or cleaned, the drive motor 142 drives the rotating shaft 143 to rotate 90 degrees, causing the protective box 2 to rotate 90 degrees. Then, the operator can insert their fingers into the protective box 2 and hold the handle 11 to rotate the movable ring 8. After the movable ring 8 is turned down, the filter plate 7 can be taken out for cleaning and replacement, which is more convenient.
