Description

Technical Field

[0001] The utility model relates to the technical field of swing-type shearing machines, in particular to a high-efficiency hydraulic swing-type shearing machine. Background Art

[0002] The swing shearing machine is a hydraulically driven shearing machine that relies on the rotation of the tool holder to achieve the shearing process. Compared with ordinary shearing machines, the swing shearing machine mostly uses oblique blade shearing. It is widely used due to its simple structure, low failure rate, high shearing efficiency and the fact that the sheet material does not bow, warp or twist after shearing.

[0003] A shearing machine is generally composed of a frame, a pressing mechanism, a blade gap adjustment device, a tool holder, a hydraulic system and other parts. Although the shearing machine uses a pressing mechanism to ensure the stability of the plate when cutting, it is often necessary to manually adjust the position, angle or direction of each plate during the feeding process of the shearing machine to ensure that the plate can be cut correctly. This will affect the efficiency of the device during continuous use, and relying on the worker's visual judgment, it will be impossible to ensure the precise alignment between the plate and the tool, which may cause inaccurate cutting and the generation of burrs and residues.

[0004] After searching, the Chinese utility model patent with publication number CN209969706U discloses a swing-type shearing machine, including a frame, a material inlet is provided at the front end of the frame, and a ventilation port is provided at the upper end; a fan is provided at the ventilation port; a feeding mechanism is horizontally provided at the material inlet; a material receiving box, a material pressing device, an upper knife, a lower knife and a hydraulic power mechanism are provided inside the frame; the material receiving box is provided at the bottom of the frame, and the material receiving box is opposite to the fan; the material pressing device is provided above the material inlet. This application replaces manual feeding by setting up a feeding mechanism consisting of a workbench and a push plate, thereby ensuring that the plate will not shift during feeding. However, when pushing the plate, the push plate can only ensure that it is in a parallel state with itself, but cannot ensure that the plate will not move along the length direction of the push plate. Therefore, the anti-shift effect achieved by the device is insufficient and cannot effectively improve the processing efficiency of the shearing machine during continuous use; secondly, when the plate is pushed and moved on the workbench, due to the large contact area between the two, the friction will also be large, so the possibility of scratching the bottom surface of the plate will be higher. Utility Model Content

[0010] Furthermore, there are four limit bars, which are fixedly connected to both sides of the top of the loading platform in groups of two. The tops of the two limit bars that are close to each other are fixedly connected with limit plates, and the outsides of the two limit plates are fixedly connected with the same slider between the two limit bars, and the slider is in the shape of an "I".

[0011] Furthermore, the top edge of the loading platform is fixedly connected to a side panel in the middle between the two groups of limit strips, a circular opening is provided on the plate body of the side panel, the folding bag is fixedly connected to the side panel outside the circular opening, an air pump is fixedly connected to the other side of the side panel at the circular opening, and fixing piles are fixedly connected to the bottom ends of both sides of the push plate, and the two fixing piles are respectively fixedly connected to the top ends of the two sliders.

[0012] Furthermore, the base is located below the loading platform, and support rods are fixedly connected to the four outer corners of the top end of the base, and sleeves are fixedly connected to the four outer corners of the bottom end of the loading platform.

[0016] 2. By designing the feeder and the swing shearing machine separately, it is not only convenient to perform maintenance on the two machines after use, but also allows the same feeder to be used with different swing shearing machines. At the same time, since the height of the loading platform of the feeder can be adjusted, the adaptability between the feeder and different models of swing shearing machines can be enhanced;

[0017] 3. Since the frame of the swing shearing machine is usually made of high-strength steel, even if the exterior is coated with anti-corrosion paint, the surface can be smooth and flat. In this case, the feeder can be connected to the swing shearing machine through the air pump suction cup to maintain the stability of the connection between the two and avoid the feeder being offset by external collisions, which may cause misalignment when the plate is fed in.

[0026] Example 1

[0027] See attached Figure 1-3The present application provides a high-efficiency hydraulic swing shearing machine, including a swing shearing machine 1 and a feeder 2. The feeder 2 is located at one side of the feed inlet of the swing shearing machine 1. The feeder 2 is used to replace conventional manual feeding, so the feeding efficiency can be improved and the feeding process can be simplified, so that the swing shearing machine 1 has higher working efficiency when used continuously. The feeder 2 includes a base 201 and a loading platform 205. The loading platform 205 is provided with a limiting mechanism, a pushing mechanism and a bearing mechanism. The limiting mechanism is used to clamp the plate to limit the plate. By limiting the plate , it can make it be in a state of alignment with the tool when feeding, so it can not only ensure the stability and effectiveness of the plate cutting process, but also be more friendly to the tool. The limiting mechanism includes clamping plates 208 on both sides of the loading platform 205. The clamping plates 208 can be used to clamp the plate so that the plate cannot be offset in the left and right directions, but can only be pushed toward the feeding port of the swing shearing machine 1. A plurality of rollers 210 are provided on the inner side of the clamping plates 208. The pushing mechanism is used to push the plate to feed the material. The pushing mechanism includes a folding bag 207 and a pushing plate 2 12. The push plate 212 is fixedly connected to one end of the folding bag 207. That is, when the air pump inflates the folding bag 207 to expand it in a directional manner, the folding bag 207 will push the push plate 212 to move the plate on the top of the ball 213 on the limit bar 214. The bearing mechanism is used to place the plate. The bearing mechanism includes a plurality of limit bars 214. The top of the limit bar 214 is provided with a groove, and the limit bar 214 is provided with a ball 213 at the groove. The ball 213 and the roller 210 can replace the limit bar 214 and the clamping plate 214 respectively. 08 comes into contact with the plate, so rolling can be used instead of friction to reduce the friction when the plate moves and avoid scratches on its surface; in addition, in order to ensure the stability of the push plate 212 in pushing the plate to move, a number of fixing clips can be set on the plate body of the push plate 212, and the plate can be fixed with the fixing clips, so that the plate can move with the push plate 212. Therefore, it is only necessary to control the inflation and deflation of the folding bag 207 by controlling the air pump to control the moving direction of the plate, thereby facilitating the removal of the cutting residue of the plate.

[0028] Preferably, a strip opening is provided in the middle of the bottom end of the loading platform 205, and the bottom end of the loading platform 205 is fixedly connected to a casing at the outside of the strip opening, and a motor is provided inside the casing. The motor can be a stepping motor. Since it can accurately control the rotation angle, it can control the moving distance of the clamping plate 208, so as to facilitate the clamping of plates 208 for different sizes. A bidirectional threaded rod 220 is rotatably connected between the inner walls on both sides of the loading platform 205, and threaded sleeves 219 are threadedly connected at both ends of the rod body of the bidirectional threaded rod 220. The transmission between the bidirectional threaded rod 220 and the threaded sleeve 219 has a reverse self-locking effect, thereby ensuring the stability of the clamping plate 208 after clamping the plate body, and pulleys 217 are keyed at the middle part of the outer side of the rod body of the bidirectional threaded rod 220 and at one end of the output shaft of the motor, and the outer sleeves of the two pulleys 217 are provided with the same belt 218, and the belt 218 is at the strip opening, and the width of the strip opening is greater than the belt width of the belt 218.

[0029] Preferably, both sides of the two threaded sleeves 219 are fixedly connected with connecting rods 211, and circular through holes are opened at both ends of both sides of the worktable 205. One end of the four connecting rods 211 extends to the outside of the worktable 205 at the four circular through holes respectively. The connecting rods 211 at the circular through holes can provide a guiding effect for the threaded sleeves 219, that is, limit its rotation so that it can only move horizontally along the bidirectional threaded rod 220. The two clamps 208 are respectively located at one end of the two connecting rods 211 on the same side, and the top and bottom ends of the two clamps 208 on the side close to each other are fixedly connected with a plurality of connecting plates 209. The number of connecting plates 209 at the top and bottom is the same and corresponds to each other up and down. The roller shaft 210 is rotatably connected between the two connecting plates 209, and the roller shaft 210 and the connecting plate 209 are rotatably connected through bearings, and the outer sleeve of the roller shaft 210 is provided with a rubber sleeve, so as to have a buffering and padding effect on the side of the plate.

[0030] Preferably, there are four limit bars 214, which are fixedly connected to both sides of the top of the loading platform 205 in groups of two. The tops of the two limit bars 214 on the sides where they are close to each other are fixedly connected with limit plates 216. The outsides of the two limit plates 216 are fixedly connected with the same slider 215 between the two limit bars 214. The slider 215 is in the shape of an "I". The sides where the two limit bars 214 are close to each other and the outer surfaces of the slider 215 and the two limit plates 216 are smoothed to ensure the smoothness of the slider 215 when moving between the two limit bars 214 and on the outsides of the two limit plates 216. The limit plates 216 can not only guide the limit bars 214, but also prevent them from tipping over, thereby ensuring the stability of the movement process. The top edge of the loading platform 205 is fixedly connected to the side panel 206 in the middle between the two groups of limit strips 214. A circular opening is opened on the plate body of the side panel 206. The folding bag 207 is fixedly connected to the side panel 206 at the outside of the circular opening. The other side of the side panel 206 is fixedly connected to an air pump at the circular opening. The air pump can adopt a dual-purpose electric air pump with a suction model of JY-017, so it can simultaneously meet the suction air demand of the folding bag 207, thereby also meeting the pushing and pulling demand of the plate by the push plate 212 equipped with the fixing clamp. Fixed piles are fixedly connected to the bottom ends of both sides of the push plate 212, and the two fixed piles are respectively fixedly connected to the top ends of the two sliders 215. The total height of the fixed piles and the slider 215 is greater than the height of the limit strip 214 with the ball 213 embedded therein, which can ensure that the movement of the push plate 212 will not be blocked by the ball 213.

[0031] Preferably, the base 201 is located below the loading platform 205, and the four outer corners of the top end of the base 201 are fixedly connected to support rods 202, and the four outer corners of the bottom end of the loading platform 205 are fixedly connected to sleeves 204. The four sleeves 204 are respectively sleeved on the outside of the four support rods 202. A threaded through hole is opened at the bottom end of one side of the sleeve 204, and the sleeve 204 is threadedly connected to the threaded through hole with a bolt 203. After loosening the bolt 203, the height of the loading platform 205 can be adjusted. Therefore, the feeder 2 can be adaptively adjusted when used for feeding platforms with different heights to ensure that the plate can enter the swing shearing machine 1 horizontally.

[0032] Working principle: When using the swing shearing machine 1, the feeder 2 can be placed in the middle of one side of the feed port of the swing shearing machine 1, and the feeder 2 can be flush and fit with the front end surface of the swing shearing machine 1, and then the height of the loading platform 205 can be adjusted after loosening the four bolts 203 respectively, so that the loading platform 205 is slightly lower than the feeding platform of the swing shearing machine 1, and the limit bar 214 is consistent with the height of the feeding platform;

[0033] Then, the plate can be placed on the stage 205 and placed on the limit bar 214, and then the motor can be started. The motor can drive the bidirectional threaded rod 220 to rotate through the belt 218 and the two pulleys 217. At this time, the two threaded sleeves 219 can move simultaneously in opposite directions outside the bidirectional threaded rod 220. Since the threaded sleeves 219 can drive the clamping plates 208 to move through the connecting rod 211, the positions of the two clamping plates 208 can be adjusted by driving the bidirectional threaded rod 220 with the motor, so that the two can clamp and limit the plate with the roller 210, and then adjust it to align with the tool of the swing shearing machine 1.

[0034] Afterwards, an air pump can be used to inflate the folding bag 207. When the folding bag 207 expands, it can push the push plate 212, and the push plate 212 can push the plate to move on the top of the ball 213 on the limit strip 214, thereby completing the feeding of the plate; after that, just continue to place the plate on the loading platform 205, and control the air pump to inflate and deflate the folding bag 207, so as to achieve continuous feeding of the swing shearing machine 1.

[0035] Example 2

[0036] See attached Figure 4 The present application provides a high-efficiency hydraulic swing shearing machine. Compared with Example 1, in order to maintain a stable state between the feeder 2 and the swing shearing machine 1, the worktable 205 is fixedly connected with threaded rods 221 at both ends of the side away from the side plate 206, and the outer parts of the two threaded rods 221 are threadedly connected with threaded sleeves 222, and one end of the two threaded sleeves 222 is fixedly connected with an air pump suction cup 223. Since the frame of the swing shearing machine 1 is often made of high-strength steel, its surface will be a flat and smooth surface. Therefore, the air pump suction cup 223 can be operated to be tightly adsorbed on the front end surface of the swing shearing machine 1, so as to achieve stable placement of the feeder 2, so as to avoid external collisions that will cause further displacement of the feeder 2, thereby affecting the stability of the plate when feeding.

[0037] Working principle: After placing the feeder 2 in front of the swing shearing machine 1, the total length of the threaded rod 221 and the threaded sleeve 222 can be adjusted according to the distance between the two. This process only requires twisting the threaded sleeve 222 to rotate. After the lengths of the above two are adjusted appropriately, the feeder 2 can be pushed again so that the air pump suction cup 223 is close to the front end surface of the swing shearing machine 1, and then the air pump suction cup 223 is operated to make it tightly adsorbed on the outer wall of the swing shearing machine 1. Therefore, the stability between the feeder 2 and the swing shearing machine 1 can be maintained to prevent external collisions from causing the feeder 2 to shift, thereby causing misalignment when the plate is fed.

[0038] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
