Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a bending machine for automotive parts processing. Background Technology

[0002] Automotive parts are the various units that make up the whole of automotive parts processing and the products that serve automotive parts processing. They are the foundation of the automotive industry and come in a wide variety of types, including engines, transmission systems, steering systems, braking systems, running systems, body accessories, etc. During the processing of automotive parts, bending machines are needed to bend them.

[0003] To address this, patent CN217701090U discloses a bending device for processing automotive parts, including a bending machine. The top of the bending machine has a movable groove, and a hydraulic press is fixedly connected to the top of the bending machine. A piston rod is fixedly connected to the output end of the hydraulic press, a connecting plate is fixedly connected to the bottom of the piston rod, and a pressure plate is fixedly connected to the bottom of the connecting plate. Connecting grooves are provided on both the left and right sides of the bottom of the connecting plate. This invention, through the coordinated arrangement of the bending machine, movable groove, hydraulic press, piston rod, connecting plate, pressure plate, hydraulic rod, spring, fixing block, pressure groove, fixing groove, connecting rod, return spring, ejector block, movable groove, and connecting groove, solves the problem that existing bending machines cannot easily remove parts from the bending groove after bending, requiring tools to remove the bent parts. It offers the advantage of easily removing parts from the bending groove.

[0004] Existing bending machines for automotive parts processing tend to accumulate waste chips in their die slots during use, making it difficult to clean them out and affecting the bending effect on automotive parts. Utility Model Content

[0005] The purpose of this invention is to provide a bending machine for processing automotive parts, in order to solve the defect of an existing bending machine for processing automotive parts, which is not convenient for cleaning out the waste chips in the die groove.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bending machine for processing automotive parts, including a fixed frame, a lifting plate installed at the top of the fixed frame, and a bending knife installed at the bottom of the lifting plate. One end of the lifting plate is connected to the output end of a drive cylinder. A base is installed at the bottom of the fixed frame, and a bending die is installed on the base. A positioning structure is provided at the top of the bending die, and a die groove is opened on the bending die. A buffer structure is provided inside the die groove, and a cleaning mechanism is provided at one end of the die groove. The cleaning mechanism includes a first screw installed inside the base, a drive motor installed at one end of the first screw, a first movable block threadedly connected to the first screw, a connecting rod connected to the first movable block, and a brush installed at one end of the connecting rod.

[0007] Preferably, the positioning structure includes a second movable block, a positioning plate, a second screw, a first gear, and a second gear. The second gear is mounted on the first screw, and the second screw is installed at both ends inside the base. The first gear is installed at one end of each of the second screws, and the second movable block is threadedly connected to each of the second screws. The positioning plate is installed at one end of each of the second movable blocks.

[0008] The above structure allows for the positioning of automotive parts of different sizes.

[0009] Preferably, the inner side of the positioning plate is provided with anti-slip texture.

[0010] The above structure increases the friction between the positioning plate and the automotive parts, thereby improving the positioning effect.

[0011] Preferably, the first gear meshes with the second gear.

[0012] With the above structure, the second gear drives the first gear to rotate, so that the second screw rotates.

[0013] Preferably, the buffer structure includes a chute, a placement groove, a buffer spring, a slider, and a top plate. The placement groove is located at the bottom of the mold groove. Buffer springs are evenly installed inside the placement groove, and a top plate is installed on the top of each buffer spring. Sliders are installed on both sides of the top plate. The chute is symmetrically located on the side wall of the mold groove.

[0014] The above structure can provide a certain buffer during bending, preventing damage to the bending die.

[0015] Preferably, the slider is inserted into the groove and forms a sliding connection therewith.

[0016] Through the above structure, the cooperation between the slider and the groove can play a certain role in limiting the top plate.

[0017] Preferably, the width of the top plate is smaller than the width of the mold groove, and the top plate and the buffer spring form a telescopic structure.

[0018] The above structure allows the top plate to move under the action of the buffer spring.

[0019] The present invention provides a bending machine for processing automotive parts, the advantages of which are: When the drive motor rotates forward, the positioning plate moves away from the bending knife, and the brush moves along the direction of the mold groove to clean out the waste in the mold groove. When the drive motor rotates in reverse, the brush returns, and the positioning plate moves closer to the bending knife to position automotive parts of different sizes.

[0020] The cleaning mechanism starts the drive motor and rotates forward. The first screw rotates, and the first movable block drives the connecting rod to move, so that the brush moves along the direction of the mold groove and pushes the waste in the mold groove out, thereby achieving the purpose of cleaning and improving cleaning efficiency. The positioning structure is designed to drive the motor to reverse, the brush to return, the second gear to drive the first gear to rotate, the second screw to rotate, and the second movable block to move the positioning plate, thereby adjusting the position of the positioning plate and achieving the purpose of positioning automotive parts of different sizes. The buffer structure reduces the impact force when the bending blade moves downward, preventing damage to the bending die from excessive impact. After bending, the buffer spring causes the ejector plate to rise, thus ejecting the material for easy removal. Attached Figure Description
