[0002] In the prior art, the tensioning mechanism is used to fix the rolled material to facilitate subsequent processing of the material; the hammer moves along the axial direction of the rolled material until it reaches the position where it needs to be hammered. However, the existing hammer is unstable during hammering, which causes the position of the hammer to deviate. Utility Model Content

[0003] This application provides a pneumatic hammer assembly for a tensioner, which solves the problem in the prior art where the hammer blade moves axially along the cylindrical material until it reaches the position to be hammered, but the existing hammer is unstable during hammering, causing the position of the hammer blade to shift.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A pneumatic hammer assembly for a tensioner includes a base, a movable component mounted on the base, a movable plate mounted on the movable component, a bracket mounted on the movable plate, a dustproof plate sliding on the bracket, a pneumatic hammer mounted on the dustproof plate, and a pushing member that drives the pneumatic hammer to move up and down. The base has a first groove; the movable component is disposed within the first groove; the movable component drives the movable plate to move; the bracket is U-shaped; the pushing member is mounted on the movable plate, and its actuating end is connected to the dustproof plate; the pneumatic hammer moves up and down synchronously with the dustproof plate; the actuating end of the pushing member corresponds to the axis of the pneumatic hammer.

[0006] As a further improvement to the above technical solution: rollers are provided on the base; two sets of rollers are arranged opposite each other; the working end of the air hammer is located in the middle between the two sets of rollers.

[0007] As a further improvement to the above technical solution: a sliding strip is provided on the dustproof plate; the dustproof plate slides up and down along the bracket via the sliding strip.

[0008] As a further improvement to the above technical solution: the pushing component is a cylinder.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. The drive design, employing a portal frame and axial alignment of the pushing component, forms a three-dimensional support frame and coaxial force transmission mechanism, effectively eliminating off-center load torque during operation and ensuring the trajectory accuracy of the air hammer's vertical movement. The composite guiding system integrates the low-friction cooperation of the sliding bar and the support guide rail, combined with the V-shaped positioning structure of the symmetrical roller group, improving motion stability while achieving precise material centering. In terms of modular design, the dynamic sealing mechanism linking the dustproof plate and the air hammer, along with the enclosed support, significantly enhances the equipment's dustproof performance.

[0014] This application provides a pneumatic hammer assembly for a tensioner, which solves the problem in the prior art where the hammer blade moves axially along the cylindrical material until it reaches the position to be hammered, but the existing hammer is unstable during hammering, causing the position of the hammer blade to shift.

[0015] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] A pneumatic hammer assembly for a tensioner includes a base 1, a movable component 2 mounted on the base 1, a movable plate 3 mounted on the movable component 2, a support 4 mounted on the movable plate 3, a dustproof plate 5 sliding on the support 4, a pneumatic hammer 6 mounted on the dustproof plate 5, and a pusher 7 that drives the pneumatic hammer 6 to move up and down. A first groove 11 is formed on the base 1. The movable component 2 is disposed within the first groove 11. The movable component 2 drives the movable plate 3 to move. The support 4 is U-shaped. The pusher 7 is mounted on the movable plate 3, and its actuating end is connected to the dustproof plate 5. The pneumatic hammer 6 moves up and down synchronously with the dustproof plate 5. The actuating end of the pusher 7 corresponds to the axis of the pneumatic hammer 6.

[0018] The base 1 is provided with rollers 8; two sets of rollers 8 are arranged opposite each other; the working end of the air hammer 6 is located in the middle between the two sets of rollers 8.

[0019] The dustproof plate 5 is provided with a sliding strip 51; the dustproof plate 5 slides up and down along the bracket 4 via the sliding strip 51.

[0020] The pusher component 7 is a cylinder.

[0021] The adoption of a drive design with the portal frame 4 and the pusher 7 aligned axially forms a three-dimensional support frame and a coaxial force transmission mechanism, effectively eliminating off-center load torque during operation and ensuring the trajectory accuracy of the vertical movement of the air hammer 6. The composite guiding system integrates the low-friction cooperation between the sliding strip 51 and the guide rail of the frame 4, combined with the V-shaped positioning structure of the symmetrical roller group 8, improving motion stability while achieving precise material centering. In terms of modular design, the dynamic sealing mechanism linking the dustproof plate 5 and the air hammer 6, along with the enclosed frame 4, significantly enhances the equipment's dustproof performance.
