Description

Technical Field

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

[0002] Steel components refer to structures made of steel plates, angle steels, channel steels, I-beams, steel pipes, flat steels and other steel materials that are assembled through welding, riveting, bolting and other methods. They are commonly used in construction, bridges, machinery, ships and other fields.

[0003] Before welding steel components, some steel plates need to be punched to facilitate the subsequent assembly of steel components. However, when the punching machine is used for a long time, the punch on the punching machine is prone to wear. When personnel replace it, they need to use various tools to disassemble and replace the punch, which is inconvenient for personnel to operate. In addition, after punching and punching the steel plate, the waste after punching will remain on the punching machine, which requires personnel to perform secondary cleaning, which is troublesome. In view of this, we propose a steel component processing punching machine. Utility Model Content

[0004] The purpose of the utility model is to provide a steel component processing punching machine to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a steel component processing punching machine, comprising:

[0006] A protection box is provided in the protection box, a working chamber is provided in the protection box, a hydraulic cylinder is fixedly installed on the top of the working chamber, a pressing block is fixedly installed on the output end of the hydraulic cylinder, a sliding groove is provided in the pressing block, a sliding block is slidably installed in the sliding groove, a threaded rod 1 is rotatably installed on the top of the sliding block and is located in the sliding groove, and the top end of the threaded rod 1 passes through the top of the sliding groove and extends into the working chamber and is fixedly installed with a knob, a card slot is provided in the sliding block, a card block is card-connected and installed in the card slot, and a punch is fixedly installed on the bottom of the card block;

[0007] A rotating groove is provided in the protection box and is located at one side of the working chamber. Extrusion plates are symmetrically and slidably installed in the rotating groove. Rubber pads are fixedly installed on opposite sides of the two extrusion plates.

[0008] A power assembly is located in the protection box and is used to drive the two extrusion plates to move closer to each other or farther away from each other;

[0009] A collecting trough is provided in the protection box and is located below the working chamber. A collecting box is slidably installed in the collecting trough. A circular hole connected to the collecting trough is provided in the protection box and at the bottom of the working chamber. A sealing plate is plugged and installed in the protection box and at one side of the working chamber.

[0010] When the punch is worn out after long-term use, the knob can be turned first, and the rotation of the knob drives the threaded rod to rotate. Under the action of the thread, the threaded rod moves downward on the lower pressure block, and the downward movement of the threaded rod drives the sliding block to move downward in the sliding groove. At the same time, the bottom end of the threaded rod rotates on the sliding block. When the slot in the sliding block is completely moved out of the sliding groove, the block can be released from the limit, and then the block can be removed from the slot, the punch to be replaced can be removed, and then the block on the new punch is stuck in the slot, and then the knob is turned. The rotation of the knob drives the threaded rod to rotate. Under the action of the thread, the threaded rod moves upward on the lower pressure block, and the upward movement of the threaded rod drives the sliding block to move upward in the sliding groove. When the slot is completely entered into the sliding groove, one side of the block will abut against the inner wall of the sliding groove, ensuring that the block will not slide in the slot, ensuring that personnel do not need to use various tools when replacing the punch, which is convenient for personnel to operate;

[0011] The power assembly is set up to drive the power assembly, and the power assembly drives the two extrusion plates to approach each other in the rotating groove. The two extrusion plates approach each other and drive the two rubber pads to approach each other until the two rubber pads clamp the steel plate. At the same time, the two rubber pads will deform to ensure that the steel plate does not slide between the two rubber pads. Then the sealing plate is inserted into the protection box, and then the hydraulic cylinder is started. The output shaft of the hydraulic cylinder drives the pressing block to move downward in the working chamber, and the pressing block drives the threaded rod 1, the sliding block, the card block and the punch to move downward. The punch moves downward to punch holes in the steel plate, and the waste material dropped by the punching will fall into the collection box through the circular hole, ensuring that the waste material after each punching will fall into the collection box, which is convenient for personnel to collect centrally.

[0012] In the above technical solution, further, the power assembly includes:

[0013] A bidirectional threaded rod is rotatably installed in a rotating groove, and one end of the bidirectional threaded rod passes through two extrusion plates. A rectangular groove is opened in the protective box and located on one side of the rotating groove. A motor is fixedly installed in the rectangular groove. The output end of the motor passes through one side of the rectangular groove and is coaxially connected to the bidirectional threaded rod.

[0014] In the present technical solution, when in use, first pull out the sealing plate from the protective box, then place the steel plate to be stamped at the bottom of the working chamber, push the steel plate until one side of the steel plate is against the inner wall of the working chamber, then start the motor, the output shaft of the motor rotates to drive the bidirectional threaded rod to rotate, the rotation of the bidirectional threaded rod drives the two extrusion plates to approach each other in the rotating groove, the two extrusion plates approach each other, driving the two rubber pads to approach each other until the two rubber pads clamp the steel plate, and at the same time the two rubber pads will deform to ensure that the steel plate does not slide between the two rubber pads.

[0015] In the above technical solution, further, the bidirectional threaded rod is threadedly connected to the two extrusion plates, the bidirectional threaded rod is provided with threads with opposite rotation directions at both ends, and the output shaft of the motor is rotationally connected to the protection box.

[0016] In this technical solution, it is ensured that the rotation of the bidirectional threaded rod can drive the two extrusion plates to move closer to or away from each other, thereby ensuring that the output shaft of the motor can rotate normally in the protective box.

[0017] In the above technical solution, further, the circular hole is located directly below the punch, and one end of the extrusion plate contacts one side of the sealing plate.

[0018] In this technical solution, the structural stability of the circular hole is ensured, and the structural stability of the extruded plate is ensured.

[0019] In the above technical solution, further, the threaded rod 1 is threadedly connected to the lower pressing block, the bottom end diameter of the punch is equal to the diameter of the circular hole, and the bottom end of the punch is plug-fitted into the circular hole.

[0020] In this technical solution, it is ensured that the threaded rod can move up and down in the lower pressing block when it rotates, so that the bottom end of the punch can be inserted into the round hole.

[0021] In the above technical solution, further, the cross-sections of the card slot and the card block are both T-shaped structures.

[0022] In this technical solution, it is ensured that the card block will not fall out of the card slot.

[0023] In the above technical solution, further, one side of the clamping block is tightly attached to the inner wall of the sliding groove.

[0024] In this technical solution, it is ensured that the sliding groove can limit the block.

[0025] The beneficial effects of the utility model are:

[0026] 1. The punching machine for processing steel components can be used with a knob. When the punch is worn out after long-term use, the knob can be turned first. The rotation of the knob drives the threaded rod to rotate. Under the action of the thread, the threaded rod moves downward on the lower pressure block. The downward movement of the threaded rod drives the sliding block to move downward in the sliding groove. At the same time, the bottom end of the threaded rod rotates on the sliding block. When the slot in the sliding block is completely moved out of the sliding groove, the block can be released from the limit, and then the block can be moved out of the slot. The punch to be replaced can be removed, and then the block on the new punch is stuck in the slot. Then the knob is turned. The rotation of the knob drives the threaded rod to rotate. Under the action of the thread, the threaded rod moves upward on the lower pressure block. The upward movement of the threaded rod drives the sliding block to move upward in the sliding groove. When the slot is completely entered into the sliding groove, one side of the block will be against the inner wall of the sliding groove to ensure that the block does not slide in the slot, so that personnel do not need to use various tools when replacing the punch, which is convenient for personnel to operate.

[0027] 2. The steel component processing punching machine drives the power assembly through the set power assembly. The power assembly drives the two extrusion plates to approach each other in the rotating groove. The two extrusion plates approach each other and drive the two rubber pads to approach each other until the two rubber pads clamp the steel plate. At the same time, the two rubber pads will deform to ensure that the steel plate will not slide between the two rubber pads. Then the sealing plate is inserted into the protection box, and then the hydraulic cylinder is started. The output shaft of the hydraulic cylinder drives the pressing block to move downward in the working chamber. The pressing block drives the threaded rod 1, the sliding block, the card block and the punch to move downward. The punch moves downward to punch holes in the steel plate, and the waste material dropped by the punching will fall into the collection box through the circular hole, ensuring that the waste material after each punching will fall into the collection box, which is convenient for personnel to collect centrally.
