Description

Technical Field

[0001] The invention relates to the technical field of brass strip processing, in particular to variable-distance slitting equipment for brass strip production. Background Art

[0002] Brass strip is a flat, long strip of metal material made of brass. It is processed into a strip product of specific thickness and width through processes such as rolling and stretching. During its processing, it needs to go through multiple steps. In actual processing, multiple processing processes can be combined in one machine tool to improve processing efficiency.

[0003] In the prior art, the Chinese patent application number CN202010421944.1 discloses a composite brass strip unloading and trimming forming device, including a trimming table, which is arranged on a base, a lifting and cutting mechanism, which is arranged on the trimming table, including a lifting plate that can be lifted and lowered toward the trimming table surface, and two cutting machines that can move toward each other along the width direction of the trimming table are arranged under the lifting plate. The trimming table is provided with a through opening for avoiding the rotation of the working end of each cutting machine and for allowing the edge of the brass strip in the width direction to move out, a leveling mechanism, which is symmetrically arranged on the trimming table and located on both sides of the lifting assembly, including a bottom pressure roller and a top pressure roller, and there is a certain gap between the bottom pressure roller and the top pressure roller for the brass strip to pass through, the bottom pressure roller and the top pressure roller are arranged correspondingly up and down, and a retractable tensioning mechanism is symmetrically arranged on the base and located on both sides of the trimming table.

[0004] In the prior art, the Chinese patent application number CN202010141089.9 discloses a brass plate and strip production device and its process, including a base, on which a rolling mill roller, a grinding device and a cutting device are installed, and the rolling mill roller and the cutting device are respectively arranged on both sides of the grinding device, and the grinding device includes a grinding disc 1, a grinding disc 2, a vertical rod, a support plate and a movable column. There are two grinding discs 1 and 2 respectively, and they are cross-arranged. The grinding disc 1 is arranged below the grinding disc 2, and two vertical rods are provided on both sides of the grinding disc 1 and the grinding disc 2 to realize the rolling, grinding, cutting and other procedures of the brass plate and strip.

[0005] In the prior art, the Chinese patent application number CN202120807296.3 discloses a composite brass strip unloading and trimming forming device, including a flattening mechanism, a waste collection mechanism and a winding mechanism. A first slide is provided on the top of the flattening mechanism and the winding mechanism, and a first slide bar is provided on the first slide. The flattening mechanism is provided with a reeling shaft, a first flattening shaft, a second flattening shaft and a third flattening shaft. The cut brass strip edge waste enters the collection box from the discharge port for collection. The brass strip after trimming is formed into an equilateral triangle by the fourth flattening shaft, the fifth flattening shaft and the sixth flattening shaft for a second tensioning and then reeled by the reeling shaft to improve the reeling effect. When reeling, it is first pressed by the second pressing device to prevent displacement during reeling, which affects the reeling effect.

[0006] Based on the above materials, it can be seen that in the existing technology, operations such as slitting and grinding can generally be combined for processing. However, in actual use, since the brass strip has a thin sheet structure, it is easy to deform during storage and processing, affecting the flatness. The uneven brass strip is prone to interlayer damage (i.e., friction damage between adjacent layers of brass strips) after winding. Summary of the Invention

[0015] Preferably, a collection box is fixedly installed at the lower end of the support frame, and flushing nozzles corresponding to the brass strips are fixedly installed inside the front and rear sides of the support frame, and the flushing nozzles are connected to the collection box through a delivery pipe.

[0016] Preferably, the collecting box corresponds to the position of the water leakage hole opened inside the fixed plate, and a heat exchange pipe with a bent structure is fixedly installed inside the collecting box, and the front end of the heat exchange pipe is connected to the air outlet of the negative pressure pump through a second connecting pipe.

[0017] Preferably, the rear end of the heat exchange pipe is fixedly connected to a third connecting pipe, and the third connecting pipe is communicated with a drying nozzle, and the drying nozzle is fixedly installed on the inner wall of the support frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the brass strip production variable-distance slitting equipment adopts a new structural design, the specific contents of which are as follows: 1. The brass strip unwound from the unwinding roller is cut and then rewound on the rewinding roller when passing through the slitting blade. The slitting blade can slide on the adjustment slide to achieve the purpose of margin. During this process, the brass strip passes through the first guide roller and the second guide roller. The first guide roller squeezes the brass strip to flatten it. At the same time, the heating wire inside the first guide roller heats it, and the heat is transferred to the brass strip through the first guide roller. The heated brass strip eliminates internal stress and improves the flattening effect. Furthermore, when the brass strip passes through the interior of the installation frame during the conveying process, the surface of the brass strip is polished by the grinding block inside the installation frame to improve its surface finish. During this process, the first guide roller drives the reciprocating screw to rotate through the synchronous belt. During the rotation of the reciprocating screw, the movable slider installed with a thread penetrating through the outside of the reciprocating screw moves back and forth in the limiting slide groove. The movable slider drives the installation frame to move back and forth synchronously, thereby making the grinding block inside the installation frame wear more evenly. Furthermore, during the grinding and polishing of the brass strip, the negative pressure pump above the mounting frame is turned on, and the negative pressure pump is used to form a negative pressure at the vacuum cleaner position. Under the action of the negative pressure, the debris generated during grinding and polishing is sucked in to avoid affecting subsequent operations.

[0019] 2. After slitting, the brass strip passes through the flushing nozzle. At this time, the water pump connected to the delivery pipe is turned on to transport the water in the collection box through the delivery pipe to the flushing nozzle and spray it out, so as to use the water flow to flush the surface of the brass strip and clean the lubricating oil and other dirt left on the surface of the brass strip during production; Furthermore, one of the air inlets of the negative pressure pump is connected to the mounting base via a first connecting pipe, and the mounting base is connected to the first guide roller via a connecting shaft, so that the air inside the first guide roller is extracted under the action of the negative pressure pump (the first guide roller contains heated hot air), and the extracted air flows into the heat exchange pipe through the second connecting pipe, and heat is exchanged with the water in the collection box through the heat exchange pipe, thereby heating the water. The heated water has a better degreasing effect; Furthermore, the air in the heat exchange pipe is transported to the drying nozzle through the third connecting pipe and ejected, so that the cleaned brass strip is dried by utilizing the ejected airflow.

The air inside the first guide roller 9 enters the interior of the connecting shaft 22, and then enters the mounting seat 21 through the connecting groove 23 at the rear end of the connecting shaft 22, and finally enters the first connecting pipe 24). The extracted hot air is transported to the interior of the heat exchange pipe 28 through the second connecting pipe 29, and heat is exchanged with the water in the collection box 26 by the heat exchange pipe 28 to achieve the purpose of heating the water in the collection box 26.
