[0006] Furthermore, two contoured toolings which are symmetrically arranged in back-to-back directions are arranged on the table top of the frame.

[0007] Furthermore, the contouring tooling comprises a positioning seat and a plugging device, the heat shrinking workpiece is placed in a groove on the positioning seat, and one end of the heat shrinking workpiece is sleeved on the plugging device.

[0008] Furthermore, the plug is a contoured tapered plug.

[0020] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] Embodiment 1:

[0022] See also Figures 1 to 3 The figure shows an anti-misoperation automobile fluid pipe heat shrink device provided by Example 1 of the present invention, including a frame 1 and a top cover 2. A contour tooling 11 is arranged on the table of the frame 1, and the heat shrink workpiece is placed on the contour tooling 11. One side of the top cover 2 in the length direction is hinged to the frame 1, and driving mechanisms 4 are symmetrically arranged at both ends of the length direction of the top cover 2. A heat source device 5 corresponding to the contour tooling 11 is arranged on the top cover 2. The heat source device 5 heats the heat shrink workpiece on the contour tooling 11, and a temperature sensor 51 is arranged in the heat source device 5.

[0023] For details, see Figures 1 to 3 Two contouring tools 11 are arranged symmetrically and facing each other on the table top of the frame 1.

[0024] For details, see Figures 1 to 3 The profiling tool 11 includes a positioning seat 111 and a plug device 112 . The heat shrink workpiece is placed in a groove on the positioning seat 111 , and one end of the heat shrink workpiece is sleeved on a plug 1121 of the plug device 112 .

[0025] For details, see Figures 1 to 3 The driving mechanism 4 is a lifting cylinder, one end of which is hinged on the table of the frame 1 and the other end is hinged on the top cover 2.

[0026] The present invention provides a heat shrink device for automobile fluid pipes that prevents misoperation. A heat shrink workpiece with a heat shrink tube is placed in a groove on a positioning seat, and one end of the heat shrink workpiece is placed on the plug of a plug device. Two back-to-back symmetrically arranged profiling tools allow the operator to easily load and unload the two profiling tools when standing in the middle. When the heat shrink workpiece is performing heat shrinking operation, the lifting cylinder does not work, the top cover is in a closed state, the PLC control device outputs power, the heat shrink time is monitored by the PLC, and the product is heat-shrinked. The PLC control device controls the locking of the top cover according to the temperature sensor in the heat source device. When the temperature is high, the PLC control device controls the lifting cylinder to not work, the top cover is locked and cannot be opened, which will not cause personal safety accidents and will not affect the quality of heat shrinkage. After the heat shrinkage is completed, the temperature feedback from the temperature sensor meets the requirements, and the lifting cylinder is controlled to open the top cover. In addition, when the temperature feedback from the temperature sensor is too high, the PLC control device controls the power of the heat source device to be reduced to ensure the heat shrinking effect.

[0027] The invention provides an automobile fluid pipe heat shrink device for preventing misoperation, which controls whether the top cover is locked according to the temperature inside the top cover fed back by a temperature sensor, thereby preventing the top cover from being opened by mistake.

[0028] Embodiment 2:

[0029] See also Figures 1 to 3 , the figure shows a heat shrink device for automobile fluid pipes that prevents misoperation provided by embodiment 2 of the present invention. This embodiment further makes the following improved technical solutions on the basis of the above embodiment: the plug 1121 is a contoured tapered plug.

[0030] The contoured tapered plug can adapt to heat shrink workpieces with different pipe diameters, and the tapered structure facilitates the heat shrink workpiece to be separated from the plug after heat shrinkage.

[0031] Embodiment three:

[0032] See also Figures 1 to 3 , the figure shows a heat shrink device for automobile fluid pipes that prevents misoperation provided by embodiment 3 of the present invention. This embodiment further makes the following improved technical solutions on the basis of the above embodiments: an infrared positioning device 6 is also provided on the contour tooling 11.

[0033] When the top cover is opened, the top cover stops opening after contacting the rays emitted by the infrared positioning device, thereby controlling the opening and closing angle of the top cover. Furthermore, the infrared positioning devices of the two profiling tools emit rays at different angles, which double-position the opening and closing angles of the top cover, thereby improving the control accuracy of the top cover opening angle and avoiding damage to the top cover and affecting the quality of heat shrinkage.

[0034] Embodiment 4:

[0035] See also Figures 1 to 3 , the figure shows an anti-misoperation automotive fluid pipe heat shrink device provided by embodiment 4 of the present invention. This embodiment further makes the following improved technical solutions on the basis of the above embodiments: the heat source device 5 includes a fixing seat 52 and a heating lamp 53, the fixing seat 52 includes two symmetrically arranged fixing plates 521, the temperature sensor 51 is fixedly mounted on the top cover 2 between the two fixing plates 521, and the heating lamp 53 is fixedly mounted on the fixing plate 521; the lower edge of the temperature sensor 51 is tangent to the upper edge of the heating lamp 53; the bottom edge of the fixing plate 521 is bent toward the inside of the fixing seat 52 to form a bent edge 5211.

[0036] The heating lamps on the two fixed plates of the heat source device are located on both sides of the heat shrink workpiece to heat the heat shrink workpiece. The lower edge of the temperature sensor is tangent to the upper edge of the heating lamp, which can more accurately reflect the temperature of the heat shrink and ensure accurate control of the processing process. The bottom edge of the fixed plate is bent toward the inside of the fixed seat to form a bent edge, which reduces the internal space of the heat source device and improves the heating effect on the heat shrink workpiece.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
