Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe processing, in particular to a pipe reducing machine for bicycle frame pipes. BACKGROUND

[0002] The current pipe reducing machine is used to expand and reduce the end face of the pipe under normal conditions. The hydraulic full-automatic pipe end processing machine controlled by the touch display screen of integrated control can perform pipe end processing forming such as pipe expansion, pipe reduction, bulging and ribbing by replacing the mold.

[0003] In the bicycle frame, the pipe reducing machine is usually used to reduce the pipe opening of the pipe material, and then the pipe material is inserted into the adjacent pipe material to splice the pipe material into a frame.

[0004] The existing pipe reducing machine usually includes a support platform, a power transmission structure, a pipe reducing structure and a stabilizing structure. In use, the pipe reducing structure and the stabilizing structure are arranged opposite to each other on the surface of the support platform, and the stabilizing structure clamps and fixes the pipe. The power transmission structure is also arranged on the support platform and located on the side away from the stabilizing structure of the pipe reducing structure. In use, when the stabilizing structure clamps and fixes the pipe, the pipe reducing structure moves towards the stabilizing structure under the pushing of the power transmission structure, and then performs pipe reducing operation on the port of the pipe.

[0005] The existing technical scheme has the following defects: the existing stabilizing structure usually only limits the first end of the pipe, and the tail end of the pipe is usually held by hand. When the length of the pipe is long, the pipe is not stable. Content of the utility model

[0006] The present application provides a pipe reducing machine for bicycle frame pipes to provide a stable support for the pipe.

[0007] The above technical purpose of the present application is achieved by the following technical scheme:

[0008] A pipe reducing machine for bicycle frame pipes, comprising a support platform and a power transmission structure, a pipe reducing structure and a stabilizing structure arranged on the support platform, the pipe reducing structure being located between the power transmission structure and the stabilizing structure, the stabilizing structure being used to fix the pipe, the power transmission structure being used to push the pipe reducing structure to move towards the stabilizing structure, thereby performing pipe reducing operation on the pipe opening of the pipe, comprising a reinforcing structure arranged on the upper surface of the support platform, the reinforcing structure being located on the side away from the pipe reducing structure of the stabilizing structure, the reinforcing structure being used to support the pipe, the reinforcing structure comprising a plurality of support assemblies and a slide rod, the slide rod being provided with two, the two slide rods being arranged in parallel and each being arranged in the length direction on the upper surface of the support platform, the support assembly being able to reciprocate in the length direction of the slide rod, and the number of support assemblies can be increased or decreased according to the length of the pipe.

[0009] By adopting the above scheme, the reinforcing structure is arranged at the rear end of the stabilizing structure, and the reinforcing structure is used to further support the pipe material. Since the slide rod is arranged, the reinforcing structure can be increased or decreased on the slide rod according to the length of the pipe material, so that the reinforcing structure provides a stable support for the pipe material. Compared with the prior art, which needs to manually hold the rear end of the pipe material for a longer pipe material, the effect of providing a stable support for the pipe material is achieved.

[0010] Further, the support assembly comprises an upper support and a lower support, the bottom wall of the lower support is provided with two ears, and a sliding hole is formed in each of the two ears, the sliding hole can reciprocate along the slide rod; the upper support is arranged on the surface of the lower support, one side of the upper support is rotatably connected with the lower support, and the other side is provided with a lock buckle; after the upper support is arranged on the lower support, the lock buckle can be operated to lock with the lower support.

[0011] By adopting the above scheme, since the sliding hole is arranged, the relative position of the lower support and the slide rod can be adjusted, the distance between two adjacent lower supports can be adjusted according to the length of the pipe material, and the upper support can further limit the pipe material. Since one end of the upper support is rotatably connected with the lower support, after the pipe material is placed on the surface of the lower support, the upper support can be rotated, so that the upper support is arranged on the surface of the lower support, so that the upper support and the lower support jointly act on the pipe material to clamp the pipe material. When the upper support and the lower support jointly act on the pipe material to clamp the pipe material, the lock buckle is used to lock the clamping state.

[0012] Further, a plurality of threaded holes are formed in the two sides of the two slide rods, and the threaded holes on each side are arranged in a linear and uniform manner on the upper surface of the support platform in a reverse direction along the length of the slide rod. Each connecting portion is fixedly connected with a connecting portion corresponding to each column of threaded holes on the two sides of the lower support, and a jack screw is formed in each connecting portion. The jack screw is threadedly connected with the connecting portion. When the relative position of the lower support and the slide rod is determined, one threaded hole corresponds to the jack screw, and the jack screw is rotated to be threadedly connected with the threaded hole.

[0013] By adopting the above scheme, the arrangement of the jack screw and the threaded hole can lock the relative position relationship between the reinforcing structure and the upper surface of the support platform.

[0014] Further, the surface of the lower support is recessed inward to form a circular-arc-shaped recess.

[0015] Further, the surface of the upper support is recessed inward to form a circular-arc-shaped clamping groove.

[0016] By adopting the above scheme, the arrangement of the recess and the clamping groove facilitates clamping of the pipe material.

[0017] Further, the surfaces of the groove and the clamping groove are provided with a buffer pad.

[0018] By adopting the above scheme, the buffer pad is arranged to protect the pipe.

[0019] Further, the surface of the support platform is provided with two inwardly recessed accommodating grooves along the length direction, and two sliding rods are arranged in the two accommodating grooves respectively, and each sliding rod is fixedly connected with the inner wall of the accommodating groove on the side close to the stabilizing structure.

[0020] Further, the end of the accommodating groove away from the stabilizing structure is provided with a through groove.

[0021] By adopting the above scheme, the accommodating groove is arranged to bear the sliding rod, and the through groove is arranged to make the end of the accommodating groove be in an open state, so as to facilitate pushing the reinforcing structure into the accommodating groove.

[0022] In summary, the present application has the following technical effects:

[0023] 1. By arranging the reinforcing structure at the rear end of the stabilizing structure, the reinforcing structure is arranged to further support the pipe. Because the sliding rod is arranged, the number of reinforcing structures on the sliding rod can be increased or decreased according to the length of the pipe, so that the reinforcing structure provides a stable support for the pipe. Compared with the prior art that the rear end of the pipe needs to be lifted by hand, the effect of providing a stable support for the pipe is achieved.

[0024] 2. By arranging the support assembly, because the sliding hole is arranged, the relative position of the lower support and the sliding rod can be adjusted, and the distance between the two adjacent lower supports can be adjusted according to the length of the pipe. The upper support is arranged to further limit the pipe. Because one end of the upper support is rotatably connected with the lower support, after the pipe is placed on the surface of the lower support, the upper support can be rotated to cover the surface of the lower support, so that the upper support and the lower support jointly clamp the pipe. When the upper support and the lower support jointly clamp the pipe, the clamping state is locked by using the lock buckle.

[0025] 3. By arranging the jackscrew and the threaded hole, the relative position relationship between the reinforcing structure and the upper surface of the support platform can be locked. BRIEF DESCRIPTION OF DRAWINGS
