Description

Technical Field

[0001] This utility model relates to the field of metal band saw technology, specifically a metal band saw for cutting sheet metal workpieces. Background Technology

[0002] Band saws are machine tools used for sawing various metal materials. They are mainly used for sawing carbon structural steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, acid-resistant steel and other alloy and metal materials. As a key piece of equipment in metal cutting machine tools, metal band saws have demonstrated the advantages of high efficiency, precision and compact structure in the sheet metal processing field.

[0003] In the field of metal processing, when metal band saws cut sheet metal workpieces, the local temperature of the cut surface can reach 300-500 degrees Celsius due to friction. After cutting, manual handling requires waiting for the workpiece to cool naturally to a touchable temperature, which forces the interruption of the production cycle and reduces production efficiency. If the high-temperature workpiece is forcibly handled, the extremely high surface temperature of the cut metal workpiece makes direct contact with the worker very likely to cause burns. This is especially true in continuous production scenarios where workers need to operate the equipment frequently, further exacerbating the safety risks. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the workpiece temperature is too high after the band saw cuts the workpiece, which poses a risk of burns to workers during handling and affects production efficiency. Therefore, this invention proposes a metal band saw for cutting sheet metal workpieces.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A metal band saw for cutting sheet metal workpieces includes a base, a band saw body fixedly mounted on the base, a fixing fixture fixedly mounted on the base, a processing platform fixedly mounted on the base in front of the fixing fixture, a material discharge port on all four sides of the processing platform, a material unloading assembly on the rear side of the processing platform, a reciprocating assembly on the side of the processing platform, a cleaning brush on the top of the processing platform on the reciprocating assembly, a transfer assembly located at the bottom of the processing platform inside the base, a blower assembly located at the top of the transfer assembly inside the base, and a waste bin at the bottom of the transfer assembly.

[0007] The feeding assembly includes a moving track, the top of the base is fixedly mounted on the moving track, a moving seat is slidably mounted on the moving track, a placement platform is fixedly mounted on the top of the moving seat, and a storage box is fixedly mounted on one end of the moving track.

[0008] The transfer assembly includes a drive motor, which is fixedly installed inside the base. A main transfer roller is fixedly installed at the output end of the drive motor. The main transfer roller is rotatably installed on the right side inside the base. A secondary transfer roller is rotatably installed on the left side inside the base. The main transfer roller is connected to the secondary transfer roller via a mesh conveyor belt. A collection hopper located at the bottom of the discharge end of the mesh conveyor belt is fixedly installed inside the base.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Preferably, the reciprocating assembly includes a geared motor, the geared motor is fixedly mounted on the base and located on the side of the processing platform, a lead screw is fixedly mounted on the output end of the geared motor, a lead screw slider is threadedly connected to the lead screw, and a cleaning brush is fixedly mounted on the lead screw slider.

[0011] Preferably, the blower assembly includes an air pump, the air pump is fixedly installed at the bottom of the base, the air outlet of the air pump is connected to an air supply pipe, the air supply pipe is connected to a nozzle, and a nozzle located at the top of the mesh conveyor belt is fixedly installed inside the base.

[0012] Preferably, a filter screen is fixedly installed inside the waste bin, a bin door located at the top of the filter screen is fixedly installed on the waste bin, and a water outlet located at the bottom of the filter screen is fixedly installed on the waste bin.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] This invention, through the setting of a feeding component and a transfer component, allows the workpiece to be fixed after cutting by releasing the fixing clamp. Then, the placement platform is pushed, and the moving seat causes the placement platform to move the cut workpiece along a moving track. At the inclined surface at the end of the moving track, the workpiece on the placement platform slides into a storage box for cooling. Simultaneously, the workpiece, cutting fluid, and metal chips fall onto a mesh conveyor belt. The mesh on the conveyor belt allows the cutting fluid and metal chips to fall through. While the workpiece is moving, a high-pressure airflow from the nozzle cleans and cools the workpiece surface. These two processes work together to quickly remove and cool the overheated metal after cutting, without affecting subsequent cutting, thus improving production efficiency and preventing material accumulation that could affect subsequent processing. Furthermore, the entire process eliminates the need for workers to touch the cut workpiece, preventing burns from the heat generated during cutting and ensuring a safe working environment for workers.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the embodiments, by Figures 1-4 A metal band saw for cutting sheet metal workpieces is provided, comprising a base 1, a band saw body 2 fixedly mounted on the base 1, a fixing fixture 3 fixedly mounted on the base 1, a processing platform 4 fixedly mounted on the base 1 in front of the fixing fixture 3, a material discharge port 41 on all four sides of the processing platform 4, a material unloading assembly 5 on the rear side of the processing platform 4, a reciprocating assembly 6 on the side of the processing platform 4, a cleaning brush 7 on the top of the processing platform 4 on the reciprocating assembly 6, a transfer assembly 8 at the bottom of the processing platform 4 inside the base 1, a blower assembly 9 at the top of the transfer assembly 8 inside the base 1, and a waste bin 10 at the bottom of the transfer assembly 8.

[0022] Reference Figures 1-2 The unloading component 5 includes a moving track 51, the top of the base 1 is fixedly installed with the moving track 51, the moving seat 52 is slidably installed on the moving track 51, the top of the moving seat 52 is fixedly installed with a placement platform 53, and one end of the moving track 51 is fixedly installed with a storage box 54.

[0023] With the above structural setup, after the workpiece is cut, the fixing clamp 3 is released from the workpiece, allowing the workpiece to fall onto the placement platform 53. Then, the placement platform 53 is pushed, and the moving seat 52 causes the placement platform 53 to move the cut workpiece along the moving track 51. The inclined surface at the end of the moving track 51 allows the workpiece on the placement platform 53 to slide into the storage box 54 for cooling. This quickly removes and cools the overheated metal after cutting, without affecting subsequent cutting. At the same time, the entire process does not require workers to touch the cut workpiece, avoiding burns caused by the heat generated during cutting when moving the workpiece.

[0024] Reference Figures 1-2 The reciprocating assembly 6 includes a geared motor 61. The geared motor 61 located on the side of the processing platform 4 is fixedly installed on the base 1. A lead screw 62 is fixedly installed at the output end of the geared motor 61. A lead screw slider 63 is threadedly connected to the lead screw 62. A cleaning brush 7 is fixedly installed on the lead screw slider 63.

[0025] With the above structural setup, after the workpiece is cut, the cut-off part of the workpiece and metal scraps fall onto the processing platform 4. Then, the reduction motor 61 is started, which drives the lead screw 62 to rotate. When the lead screw 62 rotates, it drives the lead screw slider 63 to move back and forth. When the lead screw slider 63 moves, it drives the cleaning brush 7 to sweep the workpiece and metal scraps on the processing platform 4 from the drop port 41 onto the mesh conveyor belt 84 in the base 1, so that the surface of the processing platform is always kept clean and to avoid the accumulation of waste material affecting subsequent cutting.

[0026] Reference Figures 3-4 The transfer assembly 8 includes a drive motor 81. The drive motor 81 is fixedly installed inside the base 1. The output end of the drive motor 81 is fixedly installed with a main transfer roller 82. The main transfer roller 82 is rotatably installed inside the right side of the base 1. The auxiliary transfer roller 83 is rotatably installed inside the left side of the base 1. The main transfer roller 82 is connected to the auxiliary transfer roller 83 through a mesh conveyor belt 84. The collection hopper 85 located at the bottom of the discharge end of the mesh conveyor belt 84 is fixedly installed inside the base 1.

[0027] With the above structural setup, after the workpiece and metal scraps are cleaned off, the drive motor 81 is started. The drive motor 81 drives the mesh conveyor belt 84 to move on the auxiliary conveyor roller 83 via the main transmission roller 83. With a suitable mesh size, the metal scraps on the mesh conveyor belt 84 fall through the mesh into the waste bin 10 for collection during the movement of the mesh conveyor belt 84. Then, the cut workpiece is transported to the collection hopper 85 for stacking.

[0028] Reference Figure 3The blower assembly 9 includes an air pump 91. The air pump 91 is fixedly installed at the bottom of the base 1. The air outlet of the air pump 91 is connected to an air supply pipe 92. The air supply pipe 92 is connected to a nozzle 93. The nozzle 93 located at the top of the mesh conveyor belt 84 is fixedly installed inside the base 1.

[0029] With the above structural setup, when the mesh conveyor belt 84 moves the workpiece and metal chips, the air pump 91 is activated. The air pump 91 transmits gas through the air supply pipe 92 to the nozzle 93 and sprays it out. The high-pressure airflow cleans the metal chips and attached cutting fluid on the workpiece, causing the waste on the workpiece surface to fall from the mesh into the waste bin 10, improving the cleanliness of the workpiece surface. At the same time, the airflow can also reduce the heat generated by cutting and lower the surface temperature of the workpiece.

[0030] Reference Figures 3-4 The waste bin 10 has a filter screen 101 fixedly installed inside, a bin door 102 fixedly installed on the top of the filter screen 101, and a water outlet 103 fixedly installed on the bottom of the filter screen 101.

[0031] With the above-described structure, when the metal scraps and cutting fluid falling from the mesh conveyor belt 84 land on the filter screen 101 inside the waste bin 10, the cutting fluid passes through the filter screen 101 and falls to the bottom of the waste bin 10, while the metal scraps accumulate on the filter screen 101. After accumulating to a certain amount, the cutting fluid is discharged through the outlet 103, and the metal scraps are collected by opening the bin door 102.

[0032] The implementation process of this utility model is as follows:

[0033] Step 1: Clamp the workpiece inside the fixed fixture 3, and then cut the workpiece by the band saw body 2. After the workpiece is cut, release the fixed fixture 3 to fix the workpiece, so that the workpiece falls onto the placement platform 53. Then push the placement platform 53, and the moving seat 52 makes the placement platform 53 move the cut workpiece along the moving track 51. When the inclined surface at the end of the moving track 51 is reached, the workpiece on the placement platform 53 slides into the storage box 54 for cooling. At the same time, the other part cut off falls onto the processing platform 4. Then start the reduction motor 61, which drives the lead screw 62 to rotate. When the lead screw 62 rotates, it drives the lead screw slider 63 to move back and forth. When the lead screw slider 63 moves, it drives the cleaning brush 7 to sweep the workpiece, cutting fluid and metal chips on the processing platform 4 from the discharge port 41 onto the mesh conveyor belt 84 in the base 1.

[0034] Step 2: After the workpiece and metal scraps are removed, start the drive motor 81. The drive motor 81 drives the mesh conveyor belt 84 to move on the auxiliary conveyor roller 83 via the main transmission roller 83. With a suitable mesh size, the metal scraps on the mesh conveyor belt 84 fall through the mesh into the waste bin 10 for collection during the movement. Then, the cut workpiece is transported to the collection hopper 85 for stacking. While the mesh conveyor belt 84 is moving the workpiece and metal scraps, start the air pump 91. The air pump 91 transmits gas through the air pipe 92 to the nozzle 93 and sprays it out. The high-pressure airflow cleans the metal scraps and attached cutting fluid on the workpiece, causing the waste on the workpiece surface to fall from the mesh into the waste bin 10, improving the cleanliness of the workpiece surface. At the same time, the airflow can also reduce the heat generated by cutting the workpiece and lower the surface temperature of the workpiece.
