Description

Technical Field

[0001] This utility model relates to the field of injection arm technology, and in particular to an injection arm for a bending machine. Background Technology

[0002] When bending machines perform bending operations, an injection structure is often required to enable the operating end to perform injection actions. Conventional injection actions usually involve using electric cylinders or hydraulic cylinders. However, this method generates excessive impact force during injection, causing equipment vibration, which affects the service life and operational stability of the equipment. To solve the above technical problems, the injection arm needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an injection arm for a bending machine, which has the characteristics of simplifying the injection arm structure, avoiding a large amount of impact, improving the stability of equipment operation, and increasing the service life of the equipment.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: An injection arm for a bending machine is provided, including an injection arm bracket, a left connecting block, and a right mounting seat. The injection arm bracket is elongated and consists of two pieces, arranged side-by-side. A left connecting block is installed between the left ends of the two injection arm brackets, and a right mounting seat is installed between the right ends of the two injection arm brackets. A motor mounting seat is installed in the middle between the two injection arm brackets, allowing relative sliding between the motor mounting seat and the injection arm bracket. A transmission screw is horizontally installed between the left connecting block and the right mounting seat. A transmission bushing is installed inside the left end of the motor mounting seat. The inner ring of the transmission bushing and the transmission screw are connected by a threaded structure. When the transmission bushing rotates, it drives the transmission screw, which in turn pushes the injection arm bracket, the left connecting block, and the right mounting seat, thereby creating relative movement between the injection arm bracket and the motor mounting seat.

[0005] In this technical solution, an injection arm bracket is provided to facilitate the installation of the motor mounting base, a transmission screw is provided to facilitate the relative sliding between the injection arm bracket and the motor mounting base, and a transmission shaft sleeve is provided to drive the transmission screw to rotate.

[0006] As a supplement to this technical solution, a horizontally arranged slide rail structure is installed on one side of the two injection arm brackets. Four legs are symmetrically installed on the front and rear sides of the motor mounting base. The legs cover the slide rail structure. In this technical solution, the installation of the slide rail structure and four legs is used to facilitate the stable sliding of the injection arm bracket.

[0007] As a supplement to this technical solution, a drive motor is installed on the left end of the motor mounting base, a drive wheel is installed on the main shaft of the drive motor, a driven wheel is installed on the left end of the drive shaft sleeve, and a conveyor belt is installed between the drive wheel and the driven wheel.

[0008] In this technical solution, a drive motor is installed to drive the drive wheel to rotate, a conveyor belt is installed to drive the driven wheel, and the driven wheel is installed to drive the drive shaft sleeve.

[0009] As a supplement to this technical solution, a bearing structure is fitted onto the right end of the transmission shaft sleeve. The outer ring of the bearing structure abuts against the inner ring of the motor mounting base. The installation of the bearing structure is used to ensure the stable operation of the transmission shaft sleeve.

[0010] As a supplement to this technical solution, a first telescopic sleeve is installed between the left side and the left-side mating block of the motor mounting base, and a second telescopic sleeve is installed between the right side and the right-side mounting base of the motor mounting base. The first and second telescopic sleeves cover both ends of the transmission screw. The installation of the first and second telescopic sleeves is to prevent the transmission screw from being exposed and to protect the transmission screw.

[0011] As a supplement to this technical solution, two pads are installed side by side on the right side of the middle of the left docking block.

[0012] Beneficial effects: This utility model relates to an injection arm for a bending machine. By setting an injection arm bracket, a motor mounting base is easily installed.

A transmission shaft sleeve 9 is installed inside the left end of the motor mounting seat 4. The inner ring of the transmission shaft sleeve 9 and the transmission screw 11 are connected by a threaded structure. When the transmission shaft sleeve 9 rotates, it drives the transmission screw 11, which in turn pushes the injection arm bracket 1, the left docking block 2, and the right mounting seat 3, thereby causing relative movement between the injection arm bracket 1 and the motor mounting seat 4.
