[0019] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] First, a brief overview of the basic background and main ideas of the method and use technology of the stretching correction equipment in the cold bending production process in this application is given.

[0021] As mentioned above, the inclined handrail head cover profile is a decorative component for bus-type escalators. It is formed by three-dimensional bending. Conventional bending equipment cannot bend it into place in one go. It requires a stretching correction step after the conventional bending, which is inefficient and cannot guarantee product quality. Therefore, there is an urgent need for a stretching correction device that can achieve the desired bending effect in one go, improving production efficiency and product qualification rate.

[0022] The following introduces the application of the stretching and correction equipment provided by the present invention in the stretching and correction of the inclined handrail head cover profile.

[0023] Example 1

[0024] The first embodiment of the present disclosure relates to a stretching and correction device, comprising a bed 10 and a mold fixing shaft 20 provided on the bed 10, wherein the mold fixing shaft 20 is used to mount a correction mold, and a stretching assembly is provided on one side of the mold fixing shaft 20, wherein the stretching assembly is used to stretch the profile of the correction mold;

[0025] The stretching assembly includes a clamping member 40 and a driving member 50. The clamping member 40 is used to clamp the two ends of the profile, and the driving member 50 is used to drive the clamping member 40 to move toward or away from the correction mold, so that the profile in the correction mold is stretched by external force. Figure 1 and Figure 2 shown.

[0026] In this embodiment, the clamping members 40 are arranged in pairs, and the clamping members 40 are symmetrically arranged about the mold fixing axis 10. Figure 1 shown.

[0027] Preferably, the driving member 50 may be a cylinder.

[0028] Exemplarily, the clamping member 40 includes a cover body 1 with a mold cavity 1a inside, a mold hall 2 that can be opened or closed and is located in the mold cavity 1a, the mold hall 2 includes four mold bodies 2a arranged circumferentially around the mold cavity 1a, and the multiple mold bodies 2a enclose a clamping area 2b. The above-mentioned supporting member also includes a plurality of clamps 3 that are detachably mounted on the multiple mold bodies 2a in a one-to-one correspondence. The multiple clamps 3 are all located in the clamping area 2b and can correspondingly clamp each side of the profile. Here, the clamp 3 is a purchased quick-change clamp. Figure 3 shown.

[0029] When the profile needs to be clamped, the mold hall 2 is opened, and then one end of the profile is sent into the clamping area 2b. The mold hall 2 is closed, and multiple clamps can cooperate to clamp the various sides of the profile; when the profile needs to be loosened, the mold hall 2 is opened and multiple clamps are detached from the profile. At this time, the profile can be taken out from the clamping area 2b.

[0030] When the clamp needs to be replaced or repaired, just open the mold hall and disassemble the clamp, which is simple and convenient.

[0031] In this embodiment, if Figure 4 As shown, the mold cavity 1a decreases radially from one end to the other end of the cover body 1. The clamping member 40 further includes a slide groove 7 formed on the cover body 1 from one end to the other end. The mold body 2a is provided with a slide rod 8 that fits in the slide groove 7. The mold body 2a is slidably disposed in the mold cavity 1a via the slide rod 8.

[0032] At the same time, the mold hall 2 has an open position at one end of the mold cavity 1a and a closed position at the other end of the mold cavity 1a. The diameter of the mold cavity 1a in the open position is larger than the diameter of the mold cavity 1a in the closed position. When the mold hall 2 is in the open position, the profile can be inserted into or out of the clamping area 2b; when the mold hall 2 is in the closed position, the mold hall 2 can clamp the profile.

[0033] Here, as Figure 3 As shown, the clamping member 40 further includes a cylinder 11 for driving the mold hall 2. With the cooperation of the cylinder 11, the slide rod 8, and the slide groove 7, the four mold bodies 2a can move closely against the inner wall of the cover body 1, thereby opening or closing the mold hall 2. When the cylinder 10 drives the mold hall 2 to the open position, the four mold bodies 2a are closely attached to the inner wall of the cover body 1, and a profile can be placed between the four mold bodies 2a. When the cylinder 10 drives the mold hall 2 to the closed position with a smaller gap between them, the clamps installed on the four mold bodies 2a can cooperate to clamp the profile.

[0034] The clamping member 40 further comprises a locking ring 9 sleeved on the cover body 1. The locking ring 9 is a nut ring, which is sleeved on the cover body 1 and can cooperate with the slide bar 8 to prevent the mold hall 2 from coming out of the cover body 1 during movement.

[0035] In this embodiment, if Figure 5 As shown, the clamping member further includes a plurality of mounting holes 4 corresponding to the plurality of mold bodies 2a, and first bolts 5 threaded into the mounting holes 4. The clamp 3 is removably mounted to the mold body 2a via the first bolts 5. The mounting holes 4 are adapted to extend through the housing 1 and the mold body 2a. Each mold body 2a has two mounting holes 4, which are arranged side by side on the mold body 2a. During installation, the first bolts 5 are sequentially passed through the housing 1 and the mold body 2 and connected to the clamp 3.

[0036] As a preferred solution, Figure 3 and Figure 6 As shown, the clamping member 40 further includes a position indicator 6 disposed on the mold body 2a and located between the two mounting holes 4, and a second bolt 6a for mounting the position indicator 6 on the mold body 2a. The position indicator 6 is located within the clamping area 2b. Since the mounting holes are not visible from within the clamping area 2b, the position indicator 6 allows the first bolt 5 to be screwed in one step using the position of the position indicator 6 as a reference when installing the clamp, thereby improving the installation efficiency of the clamp.

[0037] For example, a fixing frame 30 is further provided on one side of the mold fixing shaft 10, and the fixing frame 30 is used to provide a reaction force to the mold fixing shaft 20 to prevent the mold fixing shaft from bending;

[0038] The fixing frame 30 is rotatably mounted on the bed 10, and the free end of the fixing frame 30 can be connected to the mold fixing shaft. Figure 2 As shown, the crossbeam on the fixing frame 30 is connected to the mold fixing shaft 20, playing a supporting role, preventing the mold fixing shaft 20 from bending, and providing a reaction force to the mold fixing shaft 20 during stretching. Among them, the crossbeam on the fixing frame 30 is set to be detachable.

[0039] The method of using the stretching correction device of the embodiment of the present disclosure is as follows:

[0040] The calibration die is mounted on the die fixing shaft 20, and the fixing frame 30 is connected to the die fixing shaft 20 to secure the calibration die. The bent semi-finished product is then placed outside the calibration die, and both ends of the semi-finished product are clamped and secured in place within the clamping member 40. The driver 50 is activated to change the die and stretch the semi-finished product, gradually allowing it to enter the calibration die and eventually cling to it. After a period of stretching and pressure maintenance, the stretching is stopped, the clamping member is released, the finished cover is removed, and the next operation is continued. This equipment is simple and practical to manufacture, highly efficient, and produces significant forming results.
