Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a transmission structure for transporting the boom of a horizontal bending machine. Background Technology

[0002] In bending machines, there is usually a lever arm structure for bending materials. Conventional lever arm structures have a control cabinet structure installed on the upper end to control the hydraulic oil and circuit. Since the control cabinet structure is on the lever arm structure, it will greatly increase the overall weight of the lever arm structure, which will affect the movement and operation of the lever arm structure and increase the energy consumption during movement. In order to reduce the overall weight of the lever arm structure, the transmission structure needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a transmission structure for transporting the boom of a horizontal bending machine, which has the characteristics of convenient integration of cables and hydraulic pipes, avoiding the need to increase the structure of the control cabinet, smooth movement, and reduced energy consumption during operation.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a transmission structure for transporting the boom of a horizontal bending machine is provided, including a bottom slide plate, a sliding base, and a bottom panel. A motor protective cover is installed on one end of the bottom panel. A sliding base is installed on the upper end of the bottom panel near the motor protective cover. A bottom slide plate that covers both sides of the sliding base is slidably installed on the sliding base. A transverse opening is provided in the middle of both the sliding base and the bottom panel. A transmission base corresponding to the transverse opening is provided in the middle of the lower end of the bottom slide plate. A motor is installed inside the motor protective cover. A transmission screw is installed on the main shaft of the motor. A threaded match is formed between the transmission screw and the transmission base. A pipeline integration block is installed on the lower front side of the bottom slide plate. A pipeline drag chain is installed on one side of the pipeline integration block.

[0005] In this technical solution, a sliding base is installed as a slide rail base to facilitate the horizontal movement of the bottom slide plate. A bottom panel is installed to support the sliding base. A lateral perforation is provided to allow the transmission base to move along the perforation, avoiding interference. A motor and transmission screw are installed to drive the bottom slide plate. A pipeline integration block is installed to centrally connect pipelines, allowing the control cabinet for the control circuit and hydraulic lines to be located externally, significantly reducing the weight of the bending machine's lever arm and ensuring smooth lever arm transport while also reducing energy consumption. A pipeline drag chain is installed to facilitate the movement of the bottom slide plate by pulling the drag chain, preventing pipeline damage.

[0006] As a supplement to this technical solution, the motor is arranged vertically with the main shaft facing upwards. The motor protective cover is equipped with a conversion head that connects the transmission screw and the main shaft of the motor. The conversion head is equipped with a horizontal bevel gear that connects with the main shaft of the motor, and the conversion head is also equipped with a vertical bevel gear that connects with the transmission screw. The horizontal bevel gear and the vertical bevel gear mesh to realize transmission.

[0007] As a supplement to this technical solution, two contact switches are symmetrically installed on the lower rear of the bottom slide plate, and contact slopes corresponding to the two contact switches are respectively provided on the left and right sides of the rear of the bottom slide plate.

[0008] In this technical solution, the contact end of the contact switch is located on the upper side and is higher than the bottom surface of the bottom slide plate. At the same time, the contact slope is concave. When the bottom slide plate moves to the position corresponding to the contact switch, the contact end of the contact switch enters the concave contact slope. Then the contact slope can push the contact end, so that the contact switch is activated, thereby controlling the start and stop of the motor.

[0009] As a supplement to this technical solution, both ends of the sliding base are equipped with shielding chains for blocking lateral gaps, and both sides of the bottom slide are equipped with winding devices for winding the shielding chains.

[0010] In this technical solution, a shielding chain is installed to conveniently block lateral gaps and prevent dust from entering. At the same time, a winding device is installed to wind up or unwind the shielding chain.

[0011] As a supplement to this technical solution, the winding device includes a protective shell and a winding roller. The protective shell is rectangular and has an opening on its lower side. The winding roller is installed longitudinally inside the protective shell, and one end of the winding roller is connected to the shielding chain.

[0012] As the bottom slide moves, the take-up roller on one side of the bottom slide rolls to take up the shielding chain, while the take-up roller on the other side of the bottom slide rolls in the opposite direction to release the shielding chain.

[0013] As a supplement to this technical solution, a matching groove is provided in the middle of the lower end face of the bottom slide plate, extending through both ends of the bottom slide plate. A transverse sliding groove is provided on the front and rear side walls of the matching groove. The front and rear edges of the sliding base are engaged in the transverse sliding groove. A friction block that contacts the sliding base is installed on each of the three side walls at both ends of the transverse sliding groove. By providing the transverse sliding groove, the transverse sliding groove can cover the front and rear edges of the sliding base, improving the sliding stability of the sliding base. By installing the friction blocks, damage to the sliding base during sliding is avoided, thus increasing its service life.
