Description

Technical Field

[0001] The utility model belongs to the technical field of steel processing, and in particular relates to a steel punching device. Background Art

[0002] Hydraulic punching machine is a type of punching device, including split hydraulic punching machine and integrated electric hydraulic punching machine. It is mainly composed of a manual pump or electric pump and a hydraulic punching head. The oil delivery hose is connected with a hydraulic quick connector, which is reliable and fast to seal. There is no directional restriction during operation and it is easy to assemble and disassemble. It is suitable for punching L, H flat steel, steel plate and aluminum row.

[0003] At present, the working process of most hydraulic steel punching machines is to match the punching position of the steel workpiece with the punching position of the pad when in use, then start the punching machine to drive the punch head to move down, and then punch the steel workpiece. Since there is no compaction limit above the area near the steel punching hole, the instantaneous friction force can easily cause the upper end of the punching hole to deform and bulge when the punch head quickly moves out of the steel after punching. Especially for thinner steel, when the overall rigidity is poor, the possibility of deformation is greater, which reduces the effect of steel punching forming. For this reason, we have improved and designed a steel punching device. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a steel punching device to solve the above-mentioned problems in the background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A steel punching device comprises: a workbench, a punching die is installed on the workbench, a punching device is arranged above the punching die, and the punching device comprises:

[0007] A frame, the frame is fixedly connected to the workbench, and a hydraulic cylinder is installed on the top of the frame;

[0008] A connecting plate, wherein punching heads are fixedly connected around the bottom of the connecting plate, and a compacting mechanism is connected at the center of the bottom of the connecting plate.

[0009] By adopting the above-mentioned structural design, the steel punching device is provided with a compacting mechanism to reduce the deformation of the steel during the punching process, thereby improving the effect of the steel after punching and forming. The specific compacting mechanism is arranged at the bottom center of the connecting plate, and the bottom of the connecting plate is fixedly connected with a punching head around, and the upper part of the connecting plate is connected with a hydraulic cylinder. The connecting plate and the compacting mechanism and the punching head on the connecting plate are driven by the hydraulic cylinder to move, wherein the punching head punches the four corners of the steel, and the compacting mechanism compacts the center of the steel to reduce the deformation of the steel.

[0010] Further, the compacting mechanism comprises:

[0011] A fixing seat, the fixing seat is fixedly connected to the bottom of the connecting plate, and a cylindrical countersunk hole is opened on the fixing seat;

[0012] A compacting block, the top of which is fixedly connected with a connecting pin, and the connecting pin is movably arranged in the cylindrical countersunk hole;

[0013] A spring is sleeved on the outer periphery of the connecting pin and is located between the fixing seat and the compacting block.

[0014] By adopting the above structural design, the working principle of the compaction mechanism is that when punching, the compaction block at the bottom of the punching equipment first contacts the steel on the punching die, and as the hydraulic cylinder continues to advance the punching head begins to contact the steel, while the compaction block is still pressed on the surface of the steel, and at the same time the fixed seat begins to squeeze the spring, and the connecting pin also begins to rise relative to the cylindrical countersunk hole. Since the cylindrical countersunk hole has a large hole and a small hole, the head of the connecting pin has a countersunk head, so that the connecting pin can move in the cylindrical countersunk hole without being separated, and the punching head causes motion interference when punching. After the punching is completed, the punching head is separated from the contact with the steel, and the compaction block is reset and separated from the steel under the action of the spring, and the steel can be removed.

[0015] Furthermore, it also includes a limiting structure, which is arranged beside the punching die to prevent the steel conveyed from the conveying rack from sliding out of the punching die.

[0016] Furthermore, the limiting structure includes:

[0017] A bracket, the bracket is fixedly connected to the workbench, and a column is arranged on one side of the bracket close to the punching die;

[0018] A limit baffle, the limit baffle is L-shaped, and the end of the limit baffle is rotatably connected to the column;

[0019] An electric push rod is installed on the bracket and on the opposite side of the limit baffle. The movable end of the electric push rod is movably connected to the corner of the limit baffle through a connecting arm to drive the limit baffle to rotate.

[0020] Furthermore, the punching die is provided with a punching groove matched with the punching head.

[0021] Furthermore, it also includes a control unit, which is electrically connected to the punching device to control the operation of the punching device.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. The steel punching device is provided with a compaction mechanism to reduce the deformation of the steel during the punching process, thereby improving the effect of the steel after punching. Specifically, the compaction mechanism is arranged at the bottom center of the connecting plate, and a punching head is fixedly connected to the bottom of the connecting plate around the periphery. The upper part of the connecting plate is connected to a hydraulic cylinder, and the connecting plate and the compaction mechanism and the punching head on the connecting plate are driven by the hydraulic cylinder to move, wherein the punching head punches the four corners of the steel, and the compaction mechanism compacts the center of the steel to reduce the deformation of the steel;

[0024] 2. When punching, the compacting block at the bottom of the punching equipment first contacts the steel on the punching die. As the hydraulic cylinder continues to advance, the punching head begins to contact the steel. At this time, the compacting block is still pressed on the surface of the steel. At the same time, the fixed seat begins to squeeze the spring, and the connecting pin also begins to rise relative to the cylindrical countersunk hole. Since the cylindrical countersunk hole has large holes and small holes, the head of the connecting pin has a countersunk head, so that the connecting pin can move in the cylindrical countersunk hole without detaching. The punching head causes motion interference when punching. After punching is completed, the punching head is out of contact with the steel, and the compacting block is reset and detached from the steel under the action of the spring, and the steel can be removed.

[0036] Embodiment 1:

[0037] like Figure 1-5Specifically, a steel punching device comprises: a workbench 1, a punching die 2 is mounted on the workbench 1, a punching device 3 is arranged above the punching die 2, and the punching device 3 comprises: a frame 31, the frame 31 is fixedly connected to the workbench 1, a hydraulic cylinder 32 is mounted on the top of the frame 31; a connecting plate 33, a punching head 34 is fixedly connected to the bottom of the connecting plate 33, and a compacting mechanism 35 is connected to the center of the bottom of the connecting plate 33. The steel punching device is provided with a compacting mechanism 35 to reduce the deformation of the steel during the punching process, thereby improving the effect of the steel after punching and forming. The specific compacting mechanism 35 is arranged at the bottom center of the connecting plate 33, and the bottom of the connecting plate 33 is fixedly connected with a punching head 34 around it. The upper part of the connecting plate 33 is connected with a hydraulic cylinder 32. The connecting plate 33 and the compacting mechanism 35 and the punching head 34 on the connecting plate 33 are driven by the hydraulic cylinder 32 to move, wherein the punching head 34 punches the four corners of the steel, and the compacting mechanism 35 compacts the center of the steel to reduce the deformation of the steel.

[0038] In this embodiment, the compacting mechanism 35 includes: a fixed seat 351, which is fixedly connected to the bottom of the connecting plate 33 and has a cylindrical countersunk hole 3511; a compacting block 352, which has a connecting pin 354 fixedly connected to the top and movably arranged in the cylindrical countersunk hole 3511; and a spring 353, which is sleeved on the outer periphery of the connecting pin 354 and is located between the fixed seat 351 and the compacting block 352. The working principle of the compacting mechanism 35 is that when punching, the compacting block 352 at the bottom of the punching device 3 first contacts the steel 01 on the punching die 2, and as the hydraulic cylinder 32 continues to advance, the punching head 34 begins to contact the steel 01. At this time, the compacting block 352 is still pressed on the surface of the steel 01, and at the same time, the fixed seat 351 begins to squeeze the spring 353, and the connecting pin 354 also begins to rise relative to the cylindrical countersunk hole 3511. Since the cylindrical countersunk hole 3511 has a large hole and a small hole, the head of the connecting pin 354 has a countersunk head, so that the connecting pin 354 can move in the cylindrical countersunk hole 3511 without being separated, and the punching head 34 causes motion interference when punching. After punching is completed, the punching head 34 is separated from the contact with the steel 01, and the compacting block 352 is reset and separated from the steel 01 under the action of the spring 353, and the steel can be removed.

[0039] In this embodiment, a limiting structure 36 is also included. The limiting structure 36 is arranged beside the punching die 2 to prevent the steel material 01 conveyed from the conveying rack 4 from sliding out of the punching die 2.

[0040] In this embodiment, the limiting structure 36 includes: a bracket 361, which is fixedly connected to the workbench 1, and a column 3611 is provided on the side of the bracket 361 close to the punching die 2; a limiting baffle 362, which is L-shaped, and the end of the limiting baffle 362 is rotatably connected to the column 3611; an electric push rod 363, which is installed on the bracket 361 and on the opposite side of the limiting baffle 362, and the movable end of the electric push rod 363 is movably connected to the corner of the limiting baffle 362 through a connecting arm 364 to drive the limiting baffle 362 to rotate.

[0041] In this embodiment, a punching slot 21 matching with the punching head 34 is provided on the punching die 2 .

[0042] In this embodiment, a control unit 5 is further included. The control unit 5 is electrically connected to the punching device 3 to control the operation of the punching device 3 .

[0043] Working principle: The steel material 01 to be processed is transferred to the punching die 2 through the transfer rack 4. At this time, the front end of the limit baffle 362 is located at the top corner of the front end of the punching die 2 to prevent the steel material 01 from sliding directly out of the punching die 2. The punching device 3 is started by the control unit 5. The connecting plate 33 and the compacting mechanism 35 and the punching head 34 on the connecting plate 33 are driven downward by the hydraulic cylinder 32. The punching head 34 punches the four corners of the steel material, and the compacting mechanism 35 compacts the center of the steel material to reduce the deformation of the steel material. After punching, the hydraulic cylinder 32 retracts to drive the connecting plate 33 and the compacting mechanism 35 and the punching head 34 on the connecting plate 33 to move upward. The punching head 34 is out of contact with the steel material 01. The compacting block 352 is reset and detached from the steel material 01 under the action of the spring 353, and the steel material can be removed. The electric push rod 363 retracts and drives the limit baffle 362 to move away from the punching die 2 through the connecting arm 364, and then the processed steel 01 is pushed forward and taken away.
