Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for shearing machine production, and in particular relates to a pressing device for shearing machines used in cabinet production. Background Technology

[0002] According to the published patent CN213496875U, a shearing machine for cabinet production includes a housing a. A hydraulic cylinder is fixedly connected to the top of the housing a, a hydraulic rod is fixedly connected to the bottom of the hydraulic cylinder, a tool holder is fixedly connected to the bottom of the hydraulic rod, and a shearing tool is fixedly connected to the bottom of the tool holder by screws. A processing table is fixedly connected to the inner wall of the bottom of the housing a. This design effectively prevents the sheet metal from jumping during shearing, and the anti-slip teeth effectively prevent the sheet metal from slipping during pressing. However, it still has the following shortcomings:

[0003] The aforementioned equipment simply positions the sheet metal during use, resulting in poor stability. Furthermore, the shearing blade may wear down over time, leading to poor quality sheet metal after shearing. Therefore, the blade needs to be replaced promptly. However, the aforementioned equipment is not convenient for disassembling and installing the blade, which reduces production efficiency. Therefore, we propose a shearing machine pressing device for cabinet production. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing device for a shearing machine used in cabinet production. Through the pressing mechanism and auxiliary mechanism, it solves the problems of existing equipment, which simply positions the board material and has poor stability. Furthermore, the shearing blade may wear out after long-term use, resulting in low quality of the sheared board material. Therefore, it is necessary to replace the blade in a timely manner. However, existing equipment is not convenient for disassembling and installing the blade, which reduces production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a shearing machine pressing device for cabinet production, including an operating table, a connecting frame fixedly connected to the top outer wall of the operating table, a hydraulic rod fixedly connected to the outer wall of the connecting frame, a shearing blade fixedly connected to the inner wall of the operating table near the connecting frame, and a pressing mechanism provided on the outer wall of the operating table.

[0007] The pressing mechanism includes a motor, the outer wall of which is fixedly connected to the inner wall of the operating table. The bottom output end of the motor is fixedly connected to a transmission shaft via a coupling. Several gears are fixedly connected to the outer wall of the transmission shaft. Several limiting blocks are fixedly connected to the bottom outer wall of the operating table near the gears. A rack is slidably connected to the outer wall of the limiting blocks. The outer walls of the racks mesh with the outer walls of the gears. Several connecting rods are rotatably connected to the outer wall of the operating table near the racks. Several arc-shaped grooves are formed on the inner walls of the connecting rods.

[0008] Furthermore, the inner wall of the lower arc-shaped groove is slidably connected to the outer wall of the rack, and the inner wall of the upper arc-shaped groove is slidably connected to a second connecting rod. A plurality of slide rails are fixedly connected to the outer wall of the operating table near the second connecting rod. The inner wall of the slide rails is slidably connected to the outer wall of the second connecting rod. A plurality of third connecting rods are slidably connected to the outer wall of the second connecting rod. A plurality of fixed shafts are rotatably connected to the outer wall of the third connecting rod. The outer wall of the fixed shaft at the lower end is fixedly connected to the inner wall of the slide rail.

[0009] Furthermore, a pressure rod is rotatably connected to the outer wall of the fixed shaft at the upper end, and an arc-shaped groove is opened on the inner wall of one end of each of the connecting rods three near the connecting rod two. The inner wall of the arc-shaped groove is slidably connected to the outer wall of the connecting rod two. Several telescopic rods are fixedly connected to the outer wall of the arc-shaped groove, and the outer walls of the several telescopic rods are slidably connected to the inner wall of the slide rail. An auxiliary mechanism is provided on the outer wall of the operating table.

[0010] Furthermore, the auxiliary mechanism includes several slide rails, the outer walls of which are fixedly connected to the outer wall of the connecting frame.

[0011] Furthermore, a slide rod is fixedly connected to the inner wall of the slide rail two on the right side, and a threaded rod is rotatably connected to the inner wall of the slide rail two on the left side.

[0012] Furthermore, a scraper is threadedly connected to the outer wall of the threaded rod, the inner wall of the scraper is slidably connected to the outer wall of the slide rod, and several mounting blocks are fixedly connected to the bottom outer wall of the hydraulic rod.

[0013] Furthermore, shearing blades are slidably connected to the inner walls of several of the mounting blocks, and protective sleeves are slidably connected to the outer walls of the mounting blocks.

[0014] Furthermore, springs are fixedly connected to the outer walls of several of the protective sleeves, and the outer walls of several of the springs are fixedly connected to the outer walls of the hydraulic rods. A pin is inserted into the inner wall of the second shearing blade, and the outer wall of the pin is slidably connected to the inner wall of the mounting block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates an arc-shaped groove on the connecting rod. When the equipment is in use, the motor rotation drives the transmission shaft, causing multiple gears to rotate simultaneously. The gear rotation also drives multiple racks to slide in opposite directions on the limiting block. The outward movement of the racks causes the connecting rod to rotate around its own limiting shaft on the operating table. When the lower end of the connecting rod is pushed outward by the racks, the upper end of the connecting rod moves inward. This allows the plate to be positioned during shearing, ensuring that the plate does not shift during shearing and preventing it from popping out or sliding during shearing, thus avoiding accidental injury to the operator.

[0017] 2. This utility model incorporates a pin within the mounting block. During equipment use, after shearing, the sheet metal is removed, and the threaded rod is rotated. The rotation of the threaded rod causes the scraper to move on the slide rail and slide bar. The scraper's movement scrapes some of the debris scattered on both sides off the operating table. When the shearing blade wears out after prolonged use, multiple protective sleeves slide upwards to compress the mounting block. When the protective sleeves are fully lifted and the pin is exposed, the blade can be quickly disassembled and a new blade installed and adjusted when it needs to be replaced after prolonged use. This allows the shearing machine to quickly return to normal operation, improving the efficiency of the device. Simultaneously, it can clean the debris generated during the shearing process, keeping the worktable clean.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is a shearing machine pressing device for cabinet production, including an operating table 1. A connecting frame 101 is fixedly connected to the top outer wall of the operating table 1. A hydraulic rod 102 is fixedly connected to the outer wall of the connecting frame 101. A shearing blade 103 is fixedly connected to the inner wall of the end of the operating table 1 near the connecting frame 101. A pressing mechanism 2 is provided on the outer wall of the operating table 1. When the upper shearing blade 2 306 falls and aligns with the shearing blade 103, the board placed on the operating table 1 can be sheared.

[0030] The pressing mechanism 2 includes a motor 201, the outer wall of which is fixedly connected to the inner wall of the operating table 1. A drive shaft 202 is fixedly connected to the bottom output end of the motor 201 via a coupling. Several gears 203 are fixedly connected to the outer wall of the drive shaft 202, which in turn drives the gears 203. When the motor 201 is started, its rotation drives the drive shaft 202, which in turn drives the gears 203. Several limiting blocks 204 are fixedly connected to the bottom outer wall of the operating table 1 near the gears 203. A rack 20 is slidably connected to the outer wall of each limiting block 204. 5. The outer walls of several racks 205 mesh with the outer walls of gears 203. The limiting block 204 can limit the position of the racks 205, so that they can only slide on the limiting block 204. At the same time, it can prevent the racks 205 from shifting and thus failing to mesh with gears 203. Several connecting rods 206 are rotatably connected to the outer wall of the end of the operating table 1 near the racks 205. Several arc-shaped grooves 207 are opened on the inner walls of the connecting rods 206. The arc-shaped grooves 207 can adjust the position of the racks 205 and the connecting rods 208 to prevent the connecting rods 208 and the racks 205 from jamming during the movement.

[0031] The inner wall of the lower arc-shaped groove 207 is slidably connected to the outer wall of the rack 205. A connecting rod 208 is slidably connected to the inner wall of the upper arc-shaped groove 207. Several slide rails 209 are fixedly connected to the outer wall of the operating platform 1 near the connecting rod 208. The slide rails 209 can limit the movement trajectory of the connecting rod 208, allowing it to slide only on the slide rails 209. Simultaneously, the connecting rod 208 can only slide left and right along the direction of the slide rails 209. The inner wall of the slide rails 209 is slidably connected to the outer wall of the connecting rod 208. Several connecting rods 210 are slidably connected to the outer wall of the connecting rod 208. Several fixed shafts 211 are rotatably connected to the outer wall of the connecting rods 210. The outer wall of the lower fixed shaft 211 is fixedly connected to the inner wall of the slide rail 209. Through the fixed shafts 211, the position of the connecting rods 210 can be limited, allowing the arc-shaped groove 207 to move freely. The second groove 212 can only move in a circular motion around the fixed shaft 211 at the lower end. The outer wall of the fixed shaft 211 at the upper end is rotatably connected to the pressure rod 213. Several connecting rods 3 210 have arc-shaped grooves 212 on the inner wall of the end near the connecting rod 2 208. The inner wall of the arc-shaped groove 212 is slidably connected to the outer wall of the connecting rod 2 208. The arc-shaped groove 212 can make the movement of the connecting rod 2 208 more stable and prevent the connecting rod 2 208 from getting stuck at the connecting rod 3 210 when it moves. Several telescopic rods 214 are fixedly connected to the outer wall of the arc-shaped groove 212. The outer walls of the telescopic rods 214 are slidably connected to the inner wall of the slide rail 209. The outer wall of the operating table 1 is provided with an auxiliary mechanism 3. Through the telescopic rods 214, the pressure rod 213 can only move in the up and down direction to prevent the telescopic rods 214 from flipping over and affecting the subsequent normal pressing process.

[0032] The auxiliary mechanism 3 includes several slide rails 301, the outer walls of which are fixedly connected to the outer wall of the connecting frame 101. A slide rod 302 is fixedly connected to the inner wall of the right slide rail 301, and a threaded rod 303 is rotatably connected to the inner wall of the left slide rail 301. The slide rod 302 can limit the movement trajectory of the scraper 304, ensuring it can only move linearly along the direction of the slide rod 302, while also preventing the scraper 304 from falling off, thus making the movement of the scraper 304 smoother. The scraper 304 is threadedly connected to the outer wall of the threaded rod 303, and the inner wall of the scraper 304 is slidably connected to the outer wall of the slide rod 302. Several mounting blocks 305 are fixedly connected to the bottom outer wall of the hydraulic rod 102. Shear blades 306 are slidably connected to the inner wall of mounting block 305, and protective sleeves 308 are slidably connected to the outer wall of mounting block 305. Protective sleeves 308 can ensure that the pin 309 will not slide out of the mounting block 305 on its own during normal use, causing shear blades 306 to fall off. Springs 307 are fixedly connected to the outer walls of several protective sleeves 308, and the outer walls of several springs 307 are fixedly connected to the outer walls of hydraulic rods 102. Pins 309 are inserted into the inner wall of shear blades 306, and the outer wall of pins 309 is slidably connected to the inner wall of mounting block 305. Pins 309 pass through shear blades 306 and through mounting block 305 to the outer wall, thus preventing shear blades 306 from falling off mounting block 305.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, the sheet material to be cut is placed on the operating table 1. Then, the motor 201 is started. The rotation of the motor 201 drives the transmission shaft 202 to rotate, and multiple gears 203 rotate simultaneously. The rotation of the gears 203 drives multiple racks 205 to slide in opposite directions on the limit block 204. The outward movement of the racks 205 drives the connecting rod 206 to rotate around its own limit shaft on the operating table 1. When the lower end of the connecting rod 206 is pushed outward by the racks 205, the upper end of the connecting rod 206 will move inward. The movement causes connecting rod 208 to slide away from connecting rod 206 within slide rail 209. Connecting rod 208 slides within arc groove 212, causing connecting rod 210 to rotate around the lower fixed shaft 211. This causes the upper connecting rod 210 to move downwards, thereby pressing down the pressure rod 213 to clamp the plate and prevent displacement. The telescopic rod 214 allows the pressure rod 213 to move only up and down, preventing it from flipping and affecting the pressing effect. After clamping the plate, the hydraulic rod 102 is activated to press down, which in turn drives... The rack 205 moves downward, causing the second shearing blade 306 to press down. When the second shearing blade 306 and the first shearing blade 103 simultaneously press against both sides of the sheet metal, continued pressure will cut the sheet metal. Some of the resulting debris will fall directly from the operating table 1. After shearing, the sheet metal is removed, and then the threaded rod 303 is rotated. The rotation of the threaded rod 303 will drive the scraper 304 to move on the slide rail 301 and the slide bar 302. The movement of the scraper 304 can scrape some of the debris scattered on both sides off the operating table 1. When the second shearing blade 306 wears out after long-term use, multiple protective sleeves slide upward. 308 compresses the mounting block 305. When the protective sleeve 308 is fully lifted and the pin 309 is exposed, the pin 309 can be removed from the mounting block 305 and the second shearing blade 306. The second shearing blade 306 can then be removed from the mounting block 305 to replace the new blade. The spring 307 will always press down on the protective sleeve 308 due to its own elasticity, ensuring that the protective sleeve 308 will not lift up on its own when the pin 309 is properly fixed, thus preventing the pin 309 from disengaging. This helps the user to quickly replace the blade and keep the device clean for the next processing use.
