Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a clamping and pushing component for a pipe bending machine. Background Technology

[0002] A pipe bending machine is a processing device that bends pipes into desired shapes and is widely used in the automotive, aerospace, furniture, and piping engineering industries. In a pipe bending machine, the clamping and pushing assembly is one of the core functional modules, used to receive the pipe to be bent, clamp and fix it, and push it into the forming mold for bending and shaping.

[0003] Existing pipe bending machines typically employ a design where the clamping and pushing mechanisms are separate. For example, the pipe is clamped using a gripper cylinder or hydraulic clamp, and then pushed using another drive device. This structure results in complex structure, high manufacturing costs, and requires separate control of the clamping and pushing actions. The control logic is complex, and the coordination between the two actions is difficult to guarantee. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a clamping and pushing component for a pipe bending machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping and pushing assembly for a pipe bending machine, comprising: a fixed base; a clamping seat disposed on the fixed base for receiving and clamping pipes; a linear actuator connected to the clamping seat for driving the clamping seat to move relative to the fixed base; the clamping seat includes a clamping base slidably mounted on the fixed base and a guide rod passing through the clamping base; one end of the guide rod is provided with a blocking part, and the other end is provided with a clamping part, the clamping part and the clamping base being disposed opposite to each other and forming an openable and closable structure. The clamping opening is provided with a compression spring sleeved on the guide rod, which is located between the blocking part and the clamping seat. A limit part is fixed on the fixed base at the position corresponding to the blocking part. When the linear actuator drives the clamping seat to retract towards the limit part, the blocking part abuts against the limit part, and the clamping seat continues to move, forcing the compression spring to compress. At the same time, the clamping part and the clamping seat move relative to each other, causing the clamping opening to open. When the linear actuator drives the clamping seat to move away from the limit part, the blocking part and the limit part separate, and the compression spring resets, pushing the clamping seat back to its original position, causing the clamping part and the clamping seat to close relative to each other.

[0006] By adopting the above technical solution, the clamping seat and linear actuator are integrated, and the mechanical linkage of the blocking part, limiting part, and compression spring is utilized to achieve unified drive for clamping and pushing functions. When the linear actuator drives the clamping seat to retract, the blocking part and limiting part abut against each other, the clamping seat continues to move, compressing the compression spring and automatically opening the clamping opening to facilitate the acceptance of the pipe. When the linear actuator drives the clamping seat to extend, the compression spring resets, causing the clamping opening to automatically close and clamp the pipe, while the clamping seat pushes the pipe to the working position. This structure eliminates the need for a separate drive element for the clamping action, simplifying the overall structure and reducing manufacturing costs. Clamping and pushing are completed by the same actuator, resulting in simple control logic and coordinated and reliable operation.

[0007] As a preferred embodiment of this utility model, the guide rods are provided in two sets and symmetrically arranged on both sides of the clamp, and each guide rod is provided with a compression spring.

[0008] By adopting the above technical solution, the two sets of springs work synchronously, ensuring the smoothness of the opening and closing action of the clamping port and the stability when clamping the pipe, while improving the response speed and reset reliability of the component.

[0009] As a preferred embodiment of this utility model, the clamp includes a positioning plate disposed on the side facing the blocking part, and the positioning plate is provided with a positioning notch; the clamp is provided with a movable hole corresponding to the positioning notch; the guide rod passes through the positioning notch and the movable hole in sequence; the compression spring is limited between the positioning plate and the blocking part.

[0010] As a preferred technical solution of this utility model, it also includes a material rack on a fixed base, the material rack having a discharge port located above the clamping seat, and the top of the clamping seat having a baffle. When the linear drive drives the clamping seat to disengage from the material rack, the baffle moves to below the discharge port of the material rack to block the material from falling through the discharge port.

[0011] By adopting the above technical solution, when the linear actuator drives the clamp to move in the pushing direction, the baffle automatically moves below the discharge port to block the next pipe from falling; when the clamp retracts below the discharge port, the discharge port opens, and the next pipe falls into the clamping port. This structure can achieve single-pipe orderly feeding without additional sensors and control systems, avoiding jamming caused by multiple pipes falling simultaneously, simplifying the control logic, and improving production continuity.

[0012] As a preferred technical solution of this utility model, the fixed base is provided with guide rails on both sides of the clamping seat, and a conveying channel for the clamping seat to move is formed between the two guide rails.

[0013] By adopting the above technical solution, precise guidance is provided for the reciprocating motion of the clamping seat. This structure ensures the linearity of the clamping seat's motion under the drive of the linear actuator, and avoids the clamping seat from swaying or jamming during movement.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-4The clamping and pushing assembly for a pipe bending machine shown includes: a fixed base 1; a clamping seat 2, disposed on the fixed base 1, for receiving and clamping a pipe 17; a linear actuator 3, connected to the clamping seat 2, for driving the clamping seat 2 to move relative to the fixed base 1; the clamping seat 2 includes a clamping base 4 slidably mounted on the fixed base 1, and a guide rod 5 passing through the clamping base 4; one end of the guide rod 5 is provided with a blocking part 6 (blocking block or blocking plate 15, etc.), and the other end is provided with a clamping part 7, the clamping part 7 being disposed opposite to the clamping base 4 and forming an openable clamping opening 8 between them; a compression spring 9 is sleeved on the guide rod 5, the compression spring 9 being located between the blocking part 6 and the clamping base 4. The fixed base 1 has a limiting part 10 (limiting plate or limiting block, etc.) fixed at the position corresponding to the blocking part 6. When the linear actuator 3 drives the clamp 4 to retract towards the limiting part 10, the blocking part 6 abuts against the limiting part 10, the clamp 4 continues to move, forcing the compression spring 9 to compress. At the same time, the clamping part 7 (preferably a rod-shaped structure, L-shaped in this embodiment, or plate-shaped, as long as it can cooperate with the clamp 4 to achieve clamping) moves relative to the clamp 4, causing the clamping opening 8 to open. When the linear actuator 3 drives the clamp 4 to move away from the limiting part 10, the blocking part 6 separates from the limiting part 10, the compression spring 9 resets, pushes the clamp 4 back to its original position, and causes the clamping part 7 to close relative to the clamp 4.

[0022] The linear actuator 3 in this embodiment can be any one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, or other driving elements capable of linear reciprocating motion. Those skilled in the art can flexibly choose according to the actual working conditions, and will not elaborate further here.

[0023] By integrating the clamping seat 2 with the linear actuator 3 and utilizing the mechanical linkage of the blocking part 6, the limiting part 10, and the compression spring 9, a unified drive for clamping and pushing functions is achieved. When the linear actuator 3 drives the clamping seat 4 to retract, the blocking part 6 abuts against the limiting part 10, and the clamping seat 4 continues to move, compressing the compression spring 9. The clamping opening 8 automatically opens to facilitate the acceptance of the pipe 17. When the linear actuator 3 drives the clamping seat 4 to extend, the compression spring 9 resets, causing the clamping opening 8 to automatically close and clamp the pipe 17. At the same time, the clamping seat 4 pushes the pipe 17 to the working position. This structure eliminates the need for a separate drive element for the clamping action, simplifying the overall structure and reducing manufacturing costs. Clamping and pushing are completed by the same actuator, resulting in simple control logic and reliable coordinated action.

[0024] Two sets of guide rods 5 are symmetrically arranged on both sides of the clamp 4, and each guide rod 5 is equipped with a compression spring 9. The two sets of springs work synchronously, ensuring the smoothness of the opening and closing of the clamping port 8 and the stability when clamping the tube 17, while improving the response speed and reset reliability of the assembly. The clamp 4 includes a positioning plate 11 facing the blocking part 6, and the positioning plate 11 is provided with a positioning notch 12; the clamp 4 is provided with a movable hole corresponding to the positioning notch 12; the guide rods 5 pass through the positioning notch 12 and the movable hole in sequence; the compression spring 9 is limited between the positioning plate 11 and the blocking part 6.

[0025] The system also includes a material rack 13 mounted on a fixed base 1. The material rack 13 has a discharge port 14 located above the clamping seat 2. The clamping seat 4 has a baffle 15 on its top. When the linear actuator 3 drives the clamping seat 4 to disengage from the material rack 13, the baffle 15 moves below the discharge port 14 to block material from falling through the discharge port 14. When the linear actuator 3 drives the clamping seat 4 to move in the pushing direction, the baffle 15 automatically moves below the discharge port 14 to block the next pipe 17 from falling. When the clamping seat 4 retracts below the discharge port 14, the discharge port 14 opens, and the next pipe 17 falls into the clamping port 8. This structure achieves single-pipe orderly feeding without additional sensors and a control system, avoiding jamming caused by multiple pipes 17 falling simultaneously, simplifying the control logic, and improving production continuity.

[0026] The fixed base 1 is provided with guide rails 16 on both sides of the clamping seat 2, and a conveying channel for the clamping seat 2 to move is formed between the two guide rails 16. It provides precise guidance for the reciprocating motion of the clamping seat 2. This structure ensures the linearity of the movement of the clamping seat 2 under the drive of the linear actuator 3 and avoids the clamping seat 2 from swaying or jamming during the movement.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
