Technical Field
[0001] This utility model relates to the technical field of bushing processing, and in particular to a bushing pressing device. Background Technology
[0002] Automotive bushings are key components widely used in automotive chassis, suspension systems, and powertrains. They are rubber-metal composite parts that play an important role in vehicle operation, including buffering, vibration reduction, noise reduction, guidance, and positioning, significantly impacting vehicle handling, comfort, and durability. Automotive bushings typically consist of an inner metal sleeve, an outer metal sleeve, and an elastomer located between them. This structural design allows the bushing to withstand forces and torques in multiple directions, while absorbing vibrations and impacts through the deformation of the elastomer.
[0003] The prior art Chinese utility model patent with application number CN202023203115.0 relates to a bushing pressing device, which includes a body, a working groove, a driving component, a stamping component, a magnet, a guide column, a spring, and a stamping groove, etc., which can improve the safety of the equipment.
[0004] However, in actual use, the above-mentioned device does not have the ability to automatically remove the processed workpiece, which requires manual removal and increases the labor intensity of the operators. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a bushing pressing device that uses a pressing device to press and process bushings, uses a discharge device to send the processed bushings out of the processing station, and uses an auxiliary device to enable the discharge device to automatically return to its original position, thereby improving the practicality of the device.
[0006] This utility model discloses a bushing pressing device, comprising a pressing device, a discharging device, and an auxiliary device. The discharging device is installed on the pressing device, and the auxiliary device is installed on the pressing device. The pressing device performs pressing processing on the bushing, the discharging device delivers the processed bushing out of the processing station, and the auxiliary device enables the discharging device to automatically return to its original position, thereby improving the practicality of the device.
[0007] Preferably, the pressing device includes a frame, a bearing mold, a support frame, an electric cylinder, and a lifting plate. A gantry is provided on the upper part of the frame. A support frame is installed on the left side of the upper end face of the frame, and a bearing mold is installed on the right side. An electric cylinder is installed in the middle of the upper end face of the frame. A lifting plate is connected to the moving end of the electric cylinder. The left and right sides of the lifting plate are respectively provided with two sets of circular holes corresponding to the diameters of the bearing mold and the support frame, and both the bearing mold and the support frame can pass through the circular holes on the lifting plate. A hydraulic press is installed on the upper gantry of the frame, and the hydraulic press is located above the bearing mold. The workpiece is placed on the lifting plate so that the bushing pressing part of the workpiece is located on the bearing mold. The support frame provides auxiliary support for the bushing. Then, the hydraulic press on the gantry of the frame completes the pressing process of the bushing. After the processing is completed, the electric cylinder is controlled to extend and drive the lifting plate to move upward, lifting the bushing upward and separating it from the bearing mold, which improves the practicality of the device.
[0008] Preferably, the discharge device includes a rotating shaft, a discharge plate, an extension frame, a connecting block, and a first rope.

An extension frame is provided on the left and right sides of the rear part of the discharge plate. A connecting block is installed on the left and right sides of the middle of the rear end face of the frame. One end of each of the two sets of first ropes is connected to the two sets of extension frames, and the other end of the first ropes is connected to the upper end face of the connecting block. After the electric cylinder extends to a certain height, the first rope is in a taut state and pulls the extension frame downward, thereby causing the discharge plate to rotate around the rotating shaft, causing the discharge plate to tilt itself, and thus causing the bushing on the discharge plate to slide out of the processing area of the equipment, improving the practicality of the device.
[0009] Preferably, the device also includes a tension sensor and limiting rods. The lower end of the first rope is connected to the upper end face of the connecting block through the tension sensor. Multiple sets of limiting rods are provided on the lower end face of the lifting plate, and multiple sets of circular grooves are provided on the upper end face of the frame corresponding to the positions of the multiple sets of limiting rods. The tension sensor monitors the tension on the first rope. When the tension exceeds a preset value, the electric cylinder is controlled to stop extending to prevent the first rope from breaking due to excessive tension. The multiple sets of limiting rods limit the lifting process of the lifting plate and the discharge plate, reducing the vibration amplitude of the discharge plate itself during the lifting process and improving the practicality of the device.
[0010] Preferably, the auxiliary device includes a guide roller, a second rope, a counterweight, and sliding limit protrusions. A guide roller is provided at the front of the lifting plate, and a rectangular groove is provided at the front of the frame. A set of sliding limit protrusions is provided on the left and right sides of the rectangular groove.

The front of the lower end face of the discharge plate is connected to the upper end face of the counterweight via the second rope, and the middle of the second rope rests on the guide roller. The counterweight provides a downward pulling force to the front of the discharge plate, allowing the front of the discharge plate to automatically return to a horizontal position during the process of the electric cylinder retracting and driving the lifting plate and discharge plate to fall. The guide roller provides auxiliary guidance to the second rope, reducing friction loss between the second rope and the lifting plate. The sliding limit protrusions limit the position of the counterweight, improving the practicality of the device.
[0011] Preferably, the device also includes a guide plate and a vibration motor. The guide plate is mounted on the rear of the frame via a bracket. The rear of the guide plate is inclined downwards, and a vibration motor is mounted on the lower end face of the guide plate. The guide plate guides and conveys the workpieces falling from the discharge plate. At the same time, the vibration motor is turned on to drive the guide plate to vibrate, thereby preventing the workpieces from accumulating on the guide plate and being unable to slide off, thus improving the practicality of the device.
[0012] Preferably, the device also includes a conveyor frame, a conveyor belt, conveyor rollers, and a geared motor. The conveyor frame is connected to the rear end face of the frame, and multiple sets of conveyor rollers are horizontally installed on the conveyor frame. The conveyor belt is fitted onto the multiple sets of conveyor rollers, and a geared motor is installed on the side of the conveyor frame.
