Description

Technical Field

[0001] The utility model relates to the technical field of punching and shearing machines, in particular to a new type of hydraulic combined punching and shearing machine. Background Technique

[0002] Hydraulic combined punching and shearing machines are widely used in production enterprises of civil facilities such as steel structure processing, storage racks, high-voltage wire towers, telecommunication towers, street lamps, advertising signs, elevators, and ventilation ducts. They are mainly used for processing various shapes of steel and iron plates and have functions such as punching, shearing, bending, welding, and cutting. Although the existing hydraulic combined punching and shearing machines can basically meet the daily use requirements, there are still some deficiencies that need to be improved.

[0003] When the widely used hydraulic combined punching and shearing machines on the market perform punching and shearing, the material needs to be fixed under the punching and shearing head first. However, most of the existing fixing methods require manual adjustment, allowing workers to manually adjust the position of the material and the position of the clamping plate. Such an operation method not only cannot ensure the accuracy of material fixation, easily causes the punching and shearing position of the material to shift, but also has a relatively high labor intensity. Therefore, we propose a new type of hydraulic combined punching and shearing machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of hydraulic combined punching and shearing machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of hydraulic combined punching and shearing machine, including a hydraulic punching and shearing machine, on which a punching and shearing head is installed. A base is installed at the bottom of the hydraulic punching and shearing machine. An active inner cavity is opened in the base. A bidirectional threaded rod is rotatably connected inside the active inner cavity. A driving motor is installed on the right side of the base. The output end of the driving motor is connected to the end of the bidirectional threaded rod. Threaded sleeves are threadedly connected on both sides of the bidirectional threaded rod. Guide sliding grooves are opened on both sides of the base. Guide sliding rods are fixed on the front and rear sides of the two threaded sleeves. The guide sliding rods all penetrate inside the guide sliding grooves. Side clamping seats are arranged on both sides of the top of the base. The front and rear sides of the side clamping seats are fixed to the ends of the guide sliding rods through connecting brackets. Pressing components are installed on the two side clamping seats.

[0006] As a further preference of this technical solution, the pressing component includes sliding sleeves, movable connecting rods, lower pressing plates, pulling handles, and return springs. Two sliding sleeves are installed on the top of each of the two side clamping seats. Movable connecting rods are slidably connected inside the sliding sleeves. The lower pressing plates are fixed to the bottom ends of the movable connecting rods. The pulling handles are fixed to the top ends of the movable connecting rods. Return springs are wound around the outside of the movable connecting rods.

[0007] As a further preference of the present technical solution, the outer part of the guiding slide bar is fully attached to the inner wall of the guiding chute, and the guiding slide bar is slidably connected to the guiding chute.

[0008] As a further preference of the present technical solution, the input end of the driving motor is electrically connected to the output end of the control switch through a wire.

[0009] As a further preference of the present technical solution, a plurality of anti-slip grooves are equidistantly arranged at the bottom end of the lower pressing plate.

[0010] As a further preference of the present technical solution, both ends of the return spring are respectively connected to the outer wall of the lower pressing plate and the outer wall of the sliding sleeve, and the lower pressing plate is elastically connected to the sliding sleeve through the return spring.

[0011] As a further preference of the present technical solution, the outer walls of the two pull handles are both subjected to grinding treatment.

[0012] The present utility model provides a novel hydraulic combined punching and shearing machine, which has the following beneficial effects:

[0013] 1. In the present utility model, a rotatable bidirectional threaded rod is installed inside the base. The driving motor can be started to drive the bidirectional threaded rod to rotate, so that the two threaded sleeves can move towards each other under the guidance of the threads and the guiding slide bar. Thus, the guiding slide bars outside the two threaded sleeves drive the two side clamping seats to move towards each other, enabling the two side clamping seats to quickly form lateral clamping on the material placed on the base, without the need for manual fixing of the material by workers. The device can quickly form stable lateral clamping on materials of different lengths, and at the same time improves the convenience of using the device.

[0014] 2. In the present utility model, a liftable lower pressing plate is installed at the top of the two side clamping seats. The two side clamping seats drive the two lower pressing plates to move to both sides of the material. Subsequently, the upward pulling force on the two pull handles is released, and the return spring wound around the movable connecting rod releases elastic force to push the two lower pressing plates to move downward, enabling the lower pressing plates on the two side clamping seats to quickly move to both sides of the material on the base. Thus, the two lower pressing plates can form top clamping on materials of different thicknesses, avoiding the two sides of the material from warping during processing and improving the practicality of using the device.

[0024] By installing a liftable lower pressing plate 15 at the top ends of the two groups of side clamping seats 11, when the material is placed on the base 3, then the two pulling handles 16 are pulled upward, so that the two movable connecting rods 14 drive the lower pressing plate 15 to move upward, and the lower pressing plate 15 squeezes the two return springs 17 wound around the outer parts of the movable connecting rods 14.
