Description

Technical Field

[0001] This utility model belongs to the field of toy train track processing technology, and in particular relates to a track hole enlargement and shaping device. Background Technology

[0002] In the processing of precision plastic profiles such as toy train tracks, shaping and correcting their Ω-shaped cross-sections and enlarging the end connecting holes are two key post-processing steps. Current production processes generally treat shaping and enlarging as two separate workstations: first, operators clamp and correct the track profile on a shaping machine to restore its standard cross-sectional shape; then, the track is transferred to a separate enlarging machine, where the ends are manually aligned and a rotating enlarging pin is pushed in to enlarge the hole. This separate operation mode has significant limitations: on the one hand, the track lacks effective overall shape preservation during the enlarging process, and the stress generated during enlarging can easily cause secondary deformation of the shaped Ω-shaped cross-section, seriously affecting product accuracy and consistency; on the other hand, the entire process relies on manual handling and positioning, which is not only inefficient but also poses a significant safety risk because operators must hold the track barehanded near the high-speed rotating tool, and the stability of product quality is difficult to reliably guarantee. Utility Model Content

[0003] In view of this, the present invention aims to provide a track hole enlargement and shaping device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: This utility model provides a track hole enlargement and shaping device, comprising: The shaping component is slidably connected to the track to position the track and shapes the track by extrusion. A sliding component is fixedly connected to the shaping device. The shaping component is fixed on the sliding component, and the track is located above the sliding component. The sliding component is used to slide the shaping component horizontally. The hole-expanding assembly is fixedly connected to the hole-expanding and shaping device, and the hole-expanding assembly abuts against the track to form a conical friction connection. The shaping component positions and restricts the vertical or radial movement of the track, while the sliding component pushes the shaping component to slide horizontally toward the hole-expanding component, thereby shaping the track and expanding the hole at one end of the track.

[0005] In one embodiment, the shaping component includes a base, a fixing frame, a shaping fixture, and a shaping cylinder. The base is fixed to the upper end of the sliding component, the fixing frame is fixedly connected to the sliding component, the shaping cylinder is fixed on the fixing frame and the front end of the cylinder is vertically telescopic, and the shaping fixture is fixedly connected to the front end of the shaping cylinder. The shaping fixture corresponds vertically to the base. The shaping cylinder pushes the shaping fixture downward and works with the base to clamp the track to complete the shaping, or pushes the shaping fixture upward to release the track.

[0006] In one embodiment, the sliding component is a slide cylinder, the fixing frame is fixedly connected to the front end face of the slide cylinder, and the base is fixed on the sliding surface of the slide cylinder.

[0007] In one embodiment, the hole enlarging assembly includes a hole enlarging motor and a hole enlarging needle. The hole enlarging needle is installed at the output shaft end of the hole enlarging motor and is in a conical frictional connection with one end of the track. The hole enlarging motor drives the hole enlarging needle to enlarge the hole at one end of the track.

[0008] In one embodiment, the reaming needle is horizontally aligned with the base, so that the track can slide horizontally when acted upon by both the reaming needle and the base simultaneously.

[0009] In one embodiment, the hole-expanding motor is fixed inside the hole-expanding and shaping device, and the hole-expanding needle is flush with the height of the base; The axial direction of the output shaft of the reaming motor is perpendicular to the axial direction of the output shaft of the shaping cylinder, and the axial direction of the output shaft of the reaming motor is parallel to the sliding direction of the slide cylinder.

[0010] In one embodiment, the pressing down of the shaping cylinder serves as the start signal for the slide cylinder and the hole-expanding motor, enabling continuous shaping during hole expansion at one end of the track.

[0011] In one embodiment, the sliding position of the slide cylinder serves as a stop signal for the reaming motor and a rise signal for the shaping cylinder.

[0012] Beneficial effects: The present invention provides a track enlarging and shaping device. The operator places the toy train track on the slide of the slide cylinder and embeds the end to be processed into the base of the shaping component, and then presses the start button with both hands. At this point, the shaping cylinder drives the shaping fixture downwards, clamping the track together with the base to complete the positioning and shaping of its Ω-shaped cross-section. This clamping action also serves as a sensor signal, triggering the sliding assembly and the reaming assembly to start: the slide cylinder pushes the slide and track as a whole forward horizontally, while the reaming motor drives the reaming needle to rotate synchronously. During the horizontal advancement, the end of the track automatically engages with the continuously rotating reaming needle through the conical friction connection, thereby achieving precise reaming. The shaping assembly continues to function throughout the process, ensuring that the track maintains its original shape under stress. When the slide cylinder slides to the end of its stroke, its arrival signal controls the reaming motor to stop working and instructs the shaping cylinder to lift to release the track. Finally, the slide cylinder resets, completing a fully automatic processing cycle. The entire processing flow is integrated inside the device frame equipped with a safety light curtain and uses a two-hand start button, eliminating the risk of direct manual operation of the tools and greatly improving operational safety.

[0020] In the embodiments of this application, such as Figure 4The shaping assembly 1 shown includes a base 101, a fixing frame 102, a shaping fixture 103, and a shaping cylinder 104.

The front end of the cylinder is vertically telescopic. The shaping fixture 103 is fixedly connected to the front end of the shaping cylinder 104. The shaping fixture 103 corresponds vertically to the base 101. The shaping cylinder 104 pushes the shaping fixture 103 downward to cooperate with the base 101 to clamp the track and complete the shaping, or pushes the shaping fixture 103 upward to release the track. The shaping assembly 1 is used to position the track and ensure that the track maintains the Ω-shaped cross-section shape when the hole is enlarged by the hole enlarging assembly 3. In one embodiment, the sliding component 2 is a slide cylinder 201, the fixing frame 102 is fixedly connected to the front end face of the slide cylinder 201, and the base 101 is fixed on the sliding surface of the slide cylinder 201. The track is placed on the slide of the slide cylinder 201, and the end of the track to be enlarged and shaped is embedded in the base 101. The enlargement and shaping process is realized by the horizontal sliding of the slide cylinder 201.

[0021] In one embodiment, the hole enlarging assembly 3 includes a hole enlarging motor 301 and a hole enlarging needle 302. The hole enlarging needle 302 is installed at the output shaft end of the hole enlarging motor 301. The hole enlarging needle 302 is in a conical frictional connection with one end of the track.
