Description

Technical Field

[0001] This utility model relates to the field of flat steel punching and shearing, and in particular to a flat steel punching and shearing machine for pipe bracket production. Background Technology

[0002] Pipe supports are commonly used in coal mines. A pipe support is a device used to support and secure pipelines, often called a pipe hanger or pipe brace. Its main purpose is to ensure the stability of pipelines under various working environments, preventing them from shaking, deforming, or being damaged due to various loads.

[0003] Flat steel refers to steel with a width of 12-300mm, a thickness of 4-60mm, a rectangular cross-section, and slightly blunt edges. Flat steel can be used as a finished product to make pipe supports.

[0004] A shearing machine is a processing machine that performs operations such as shearing, cutting, and punching on steel plates according to processing requirements. It generally includes a punching shear head and a drive cylinder that drives the punching shear head to rise and fall. During processing, the drive cylinder drives the punching shear head to descend and contact the steel plate to be processed, and the steel plate is sheared accordingly.

[0005] For example, patent document CN222919446U discloses a punching and shearing machine, relating to the field of punching and shearing technology. It includes a punching and shearing machine body, a punching and shearing cylinder mounted on the machine body, a mounting plate fixedly connected to the piston end of the punching and shearing cylinder, and a punching and shearing head connected to the bottom of the piston end of the punching and shearing cylinder. A clamping mechanism is provided on the mounting plate. A worktable is connected to the punching and shearing machine body via multiple support columns. The worktable has punching holes for the punching and shearing head to pass through. A discharge plate with an inclined slope is fixedly installed directly below the punching holes. A waste collection box is connected to the adjacent side of the bottom end of the slope of the discharge plate. A collection cover is connected to the side of the waste collection box, and the collection cover has a notch. A blowing fan, flush with the worktable and facing the notch, is installed on the punching and shearing machine body. This solves the problem that during metal punching, metal chips and scrap are generated, which fall onto the processing table and require frequent cleaning by the user, thus reducing the punching speed.

[0006] In the prior art, the tube support is generally a semi-circular metal plate with straight connecting ears fixed on both sides, and through holes are opened on the straight connecting ears. In order to improve processing efficiency, there is a bending and punching machine that integrates punching, bending and shearing. However, the defect of this device is that there is no dedicated material collection and stacking mechanism, which results in the collected tube supports being messy and disorganized. This leads to a small amount of material collected at one time, increases the number of transportation times, and still requires manual stacking in subsequent processing. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-9As shown, a flat steel punching and shearing machine for producing pipe supports includes a punching and shearing mechanism, a bending mechanism on the front side of the punching and shearing mechanism, and a material receiving mechanism on one side of the bending mechanism. The material receiving mechanism is used to collect pipe supports 4. The pipe supports 4 are generally semi-circular metal plates with straight connecting ears fixedly connected to both sides, and through holes are opened on the straight connecting ears. The punching and shearing mechanism includes a main support 101, a cutting die 103 bolted to the main support 101 for cutting the flat steel after bending, and a punching die 104 bolted to the main support 101 for punching the flat steel. The upper punch shearing through hole and the material receiving mechanism include a flipping bracket 301 rotatably connected to the bending mechanism. A telescopic cylinder 302 is bolted to one side of the flipping bracket 301. The telescopic cylinder 302 is perpendicular to the flipping bracket 301. A fixed bracket 303 is bolted to the output end of the telescopic cylinder 302. A material receiving rack 304 is slidably connected to the fixed bracket 303. Two symmetrically arranged cylinders are welded to the other side of the material receiving rack 304. The diameter of the cylinders is smaller than the diameter of the through hole on the pipe support 4, and the height of the cylinders is more than four times the thickness of the flat steel. The cylinders on the material receiving rack 304 can... A return spring 305 is fixedly connected between the fixed bracket 303 and the receiving rack 304 through the through hole on the pipe support 4. A receiving table assembly is provided on one side of the bending mechanism. After the flat steel is bent, the telescopic cylinder 302 drives the fixed bracket 303 to rise, and the fixed bracket 303 drives the receiving rack 304 to rise. During this process, the cylinder on the receiving rack 304 passes through the through hole on the pipe support 4. Then the flat steel needs to be retracted to cut the bent pipe support 4 and the original flat steel. During this process, the receiving rack 304 and the fixed bracket 303 slide relative to each other. After the cutting is completed, the receiving rack 304... 4. The tube bracket 4 is reset under the action of the reset spring 305. Then the flipping bracket 301 is flipped 90 degrees. In this way, the receiving rack 304 drives the tube bracket 4 to flip 90 degrees. During the flipping process, the tube bracket 4 will not fall off due to the limit of the cylinder and the through hole. Thus, the tube bracket 4 is placed horizontally on the sliding platform 310. Then the telescopic cylinder 302 drives the fixed bracket 303 to move again. Thus, the tube bracket 4 is pushed. Then the telescopic cylinder 302 is reset, and the receiving rack 304 is separated from the tube bracket 4. This operation is repeated. Several tube brackets 4 are neatly stacked on the sliding platform 310.

[0033] The punching and shearing mechanism also includes several hydraulic telescopic rods 102 fixedly connected to the top of the main support 101. The output ends of two hydraulic telescopic rods 102 are fixedly connected to the cutting die 103 and the punching die 104, respectively. The cutting die 103 and the punching die 104 are existing technologies, and their specific structures will not be described here. A bidirectional screw 105 is rotatably connected to the rear side of the main support 101. Two symmetrically arranged clamping roller assemblies 106 are threaded onto the bidirectional screw 105. An adjusting nut 111 is fixedly connected to one side of the bidirectional screw 105. To ensure that the flat steel does not deviate during the conveying process from the sliding frame 107 to the punching die 104, two clamping roller assemblies 106 are set to clamp the flat steel. The bidirectional screw 105 ensures that the two clamping roller assemblies 106 have good centering ability. The operator can drive the bidirectional screw 105 to rotate by adjusting the nut 111. The bidirectional screw 105 drives the clamping roller assemblies 106 to move towards or away from each other.

[0034] A sliding frame 107 is slidably connected to the rear side of the main support 101. The sliding frame 107 and the main support 101 are limited by bolts. The relative position of the sliding frame 107 and the main support 101 can be adjusted by adjusting the bolts, so as to accommodate flat steel of different thicknesses. A movable roller 108 is rotatably connected to the bottom of the sliding frame 107. A fixed roller 109 is set below the movable roller 108. The fixed roller 109 is rotatably connected to the main support 101. A conveyor motor 110 is fixedly connected to one side of the main support 101. The output end of the conveyor motor 110 is fixedly connected to the fixed roller 109. The flat steel, after passing through the straightening device, passes between the sliding frame 107 and the movable roller 108. The conveyor motor 110 drives the movable roller 108 to rotate. The movable roller 108 drives the flat steel forward and enters the punching die 104 and the cutting die 103. Then, the rear hydraulic telescopic rod 102 pushes the punching die 104 to punch holes in the flat steel. After bending is completed, the front hydraulic telescopic rod 102 pushes the cutting die 103 to cut the flat steel.

[0035] The bending mechanism includes a bending bracket 201 fixedly connected to the front side of the main support 101. A translation screw 202 is rotatably connected to the top of the bending bracket 201. A translation motor 203 is fixedly connected to one side of the bending bracket 201. The output end of the translation motor 203 is fixedly connected to the translation screw 202. A translation bracket 204 is slidably connected to the top of the bending bracket 201. The translation bracket 204 is threadedly connected to the translation screw 202. A clamping column 206 is fixedly connected to one side of the top of the translation bracket 204. A driven gear 205 is rotatably connected to the clamping column 206. Two symmetrically positioned gears are rotatably connected to one side of the driven gear 205. The bending column and the top of the translation bracket 204 are fixedly connected to a bending motor 208. The output end of the bending motor 208 is fixedly connected to a drive gear 207. The drive gear 207 meshes with the driven gear 205. The flat steel after punching passes through the clamping column 206. Then the bending motor 208 drives the drive gear 207 to rotate. The drive gear 207 drives the driven gear 205 to rotate. The driven gear 205 drives the bending column on it to rotate. Through the cooperation of the clamping column 206, the bending column on the driven gear 205, and the fixed roller 109 driving the flat steel to move, the flat steel can be bent into the outer shape of the pipe bracket 4.

[0036] A linkage rack 306 is fixedly connected to the bottom of the translation bracket 204, and a linkage gear 307 is fixedly connected to one side of the flip bracket 301. The linkage rack 306 meshes with the linkage gear 307. After bending, the translation motor 203 drives the translation screw 202 to rotate, and the translation screw 202 drives the translation bracket 204 to move. When the translation bracket 204 moves, the clamping column 206 disengages from the flat steel. When the translation bracket 204 moves, it drives the linkage rack 306 to move. The linkage rack 306 drives the linkage gear 307 to rotate, and the linkage gear 307 drives the flip bracket 301 to rotate ninety degrees, so that the flip bracket 301 is in a vertical state.

[0037] A U-shaped frame 308 is fixedly connected to one side of the bending bracket 201. A baffle 309 is fixedly connected to the top of the U-shaped frame 308. The baffle 309 can prevent the stacked pipe supports 4 from falling off the sliding platform 310. A sliding platform 310 is set in the middle of the U-shaped frame 308. Several stacked pipe supports 4 can be placed on the top of the sliding platform 310. Several translation wheels 311 are fixedly connected to the bottom of the sliding platform 310. A traction frame is set on the front of the sliding platform 310. When several pipe supports 4 are stacked on the sliding platform 310 to the maximum capacity, the worker can pull the sliding platform 310 out of the U-shaped frame 308 through the traction frame, and then put the empty sliding platform 310 into the U-shaped frame 308 to continue the material collection.

[0038] Working principle: The flat steel, after passing through the straightening device, passes between the sliding frame 107 and the movable roller 108. The conveying motor 110 drives the movable roller 108 to rotate, which in turn drives the flat steel forward into the punching die 104 and the cutting die 103. Subsequently, the rear hydraulic telescopic rod 102 pushes the punching die 104 to punch holes in the flat steel. To ensure that the flat steel does not deviate during the conveying process from the sliding frame 107 to the punching die 104, two clamping roller assemblies 106 are set to clamp the flat steel. The bidirectional screw 105 ensures that the two clamping roller assemblies 106 have good centering ability. The operator can drive the bidirectional screw 105 to rotate by adjusting the nut 111. The bidirectional screw 105 drives the clamping rollers. Components 106 move towards or away from each other. The punched flat steel passes through the clamping column 206. Then, the bending motor 208 drives the drive gear 207 to rotate. The drive gear 207 drives the driven gear 205 to rotate. The driven gear 205 drives the bending column on it to rotate. Through the cooperation of the clamping column 206, the bending column on the driven gear 205, and the fixed roller 109 driving the flat steel to move, the flat steel can be bent into the outer shape of the pipe bracket 4. After bending, the translation motor 203 drives the translation screw 202 to rotate. The translation screw 202 drives the translation bracket 204 to move. When the translation bracket 204 moves, the clamping column 206 disengages from the flat steel. When the translation bracket 204 moves, it drives the linkage rack 306 to move. The rack 306 drives the connecting gear 307 to rotate, which in turn drives the tilting bracket 301 to rotate 90 degrees, bringing it to a vertical position. After bending the flat steel, the telescopic cylinder 302 drives the fixed bracket 303 to rise, which in turn drives the receiving rack 304 to rise. During this process, the cylinder on the receiving rack 304 passes through the through hole on the pipe support 4. Then, the flat steel is retracted to cut the bent pipe support 4 from the original flat steel. During this process, the receiving rack 304 and the fixed bracket 303 slide relative to each other. After cutting, the receiving rack 304 returns to its original position under the action of the return spring 305. Then, the translation bracket 204 moves to its original position, causing the tilting bracket 301 to rotate 90 degrees, thus collecting the material. The frame 304 rotates the pipe support 4 ninety degrees. During the rotation, the pipe support 4 will not fall due to the limiting effect of the cylinder and the through hole. Thus, the pipe support 4 is placed horizontally on the sliding platform 310. Then, the telescopic cylinder 302 drives the fixed bracket 303 to move again, thus pushing the pipe support 4. After that, the telescopic cylinder 302 resets, and the receiving frame 304 is separated from the pipe support 4. This operation is repeated, and several pipe supports 4 are neatly stacked on the sliding platform 310. When the stacking of several pipe supports 4 on the sliding platform 310 reaches the upper limit, the worker can pull the sliding platform 310 out of the U-shaped frame 308 using the traction frame. Then, the empty sliding platform 310 is put into the U-shaped frame 308 to continue receiving materials.
