Description

Technical Field

[0001] The invention belongs to the technical field of window frame processing, and specifically refers to a splicing device for plastic steel window frames. Background Art

[0002] Plastic steel is the abbreviation of plastic steel, also known as PVC profile, which is a new type of building material. It has excellent rigidity, elasticity, corrosion resistance and anti-aging properties. It is often used to make window frames for sliding doors and windows. The window frame consists of 4 profiles, each of which has 45° corners cut at both ends. The 45° corners of the two adjacent profiles are fitted together, and finally the 45° corners of the two adjacent profiles are fixed.

[0003] In the related art, the application document with the announcement number CN112959676B discloses a plastic steel window frame splicing device and its process, including a workbench, a lifting component, a plurality of clamping components and a plurality of cutting components. During operation, the clamping component is used to clamp the profile, and then the lifting component drives the cutting component to move downward, and the profile is cut during the downward movement of the cutting component; by setting the lifting component, the plurality of clamping components and the plurality of cutting components, the two corners of a profile can be cut synchronously at one time, and there is no need for personnel to turn the profile, which simplifies the production operation process of personnel. However, the horizontal position of the hot melt component of the device is fixed and cannot be adjusted. In actual processing, the diagonal of the processed window frame will change with the different processing sizes of the window frame. The existing window frame splicing equipment lacks the function of automatically adjusting the hot melt component. In addition, when the existing splicing equipment fixes the profile, it is necessary to set up multiple sets of clamping mechanisms for fixing, which has a complex structure and cumbersome operation steps.

[0052] like Figure 1-Figure 13 As shown, the mounting frame 3 is provided with a controller 46, and the controller 46 is provided with a display 50. The controller 46 is electrically connected to the display 50 and the angle sensor 59 respectively. The controller 46 controls the angle sensor 59 to respectively detect the rotation angles of the first rotating frame 26 and the second rotating frame 27, and displays the detection results on the display 50.

[0053] When in use, firstly, the electrical components in the device are connected to an external power supply and a control switch, and four profiles are placed in four groups of fixed mounting seats 10 and movable mounting seats 11 respectively. The angle of the diagonal of the window frame is calculated according to the internal size of the window frame to be processed (window hole), and then the tightening screw 52 is screwed to fix the central bevel gear 28 so that the central bevel gear 28 cannot rotate. At this time, the first rotating frame 26 and the second rotating frame 27 are rotated in opposite directions synchronously, and the angle between the first rotating frame 26 and the second rotating frame 27 is adjusted to be equal to the angle of the diagonal of the window frame. The controller 46 controls the rotation angle sensor 59 to detect the rotation angle of the first rotating frame 26 and the second rotating frame 27 respectively, and the detection result is displayed on the display 50 for convenient and precise adjustment. After the angle adjustment is completed, the third drive is controlled to The movable cylinder 72 drives the pressure plate 1 74 and the pressure plate 2 56 to move downward, and the pressure plate 1 74 and the pressure plate 2 56 respectively press the first rotating frame 26 and the second rotating frame 27 to prevent them from rotating, so as to avoid the first rotating frame 26 and the second rotating frame 27 from offsetting when the central bevel gear 28 rotates. The first motor 53 is started, and the first motor 53 drives the bidirectional screw rod 15 to rotate, and the bidirectional screw rod 15 drives the adjusting slide 16 and the adjusting slide 2 17 to move along the first direction to adjust the distance between the two groups of adjusting devices 2 7, thereby driving the four groups of fixed mounting seats 10 symmetrically arranged to move closer to each other in pairs along the first direction. When the profiles arranged above the adjusting device 1 6 are respectively in contact with the electric heating plates 13 at both ends thereof, the first motor 53 is turned off. In the initial state, the electric heating plates 13 are arranged at Between the fixed mounting seat 10 and the movable mounting seat 11, the electric heating plate 13 is not turned on, and then the second motor 54 is started, the second motor 54 drives the bidirectional screw rod 20 to rotate, and the bidirectional screw rod 20 drives the two symmetrically arranged mounting slides 9 to slide close or separate along the second direction, and the mounting slide 9 drives the two clamped profiles to move toward each other through the fixed mounting seat 10. At the same time, the mounting slide 9 drives the symmetrically arranged movable mounting seat 11 to move toward each other, so that the profile arranged above the adjusting device 2 7 is clamped between the two symmetrically arranged movable mounting seats 11. When the profile arranged above the adjusting device 2 7 contacts the electric heating plates 13 at both ends thereof respectively, the second motor 54 is turned off. At this time, the beveled surfaces of the four profiles are in close contact with the electric heating plate 13, and then Then the clamping motor 39 is started, and the clamping motor 39 drives the central shaft 33 to rotate. The central shaft 33 drives the first bevel gear 29 and the second bevel gear 30 to rotate synchronously through the central bevel gear 28, and the first screw 36 and the second screw 38 rotate synchronously, thereby driving the clamping slide 1 41 and the clamping slide 2 43 to move synchronously away from the central fixed seat 25. The two clamping slides 1 41 and the two clamping slides 2 43 move along the four corners of the window frame close to the four corners surrounded by the four profiles. The clamping slide 1 41 and the clamping slide 2 43 respectively drive the four groups of inner support clamping assemblies 61 to move close to the four corners inside the window frame. The cross bar 69 limits the inner support clamping assembly 61, so that the inner support plates 65 at both ends of the L-shaped bracket 64 always remain parallel to the dynamic mounting seat 11 and the fixed mounting seat 10.When the inner support plates 65 are respectively tightly fitted with the inner walls of the profiles, the clamping motor 39 is controlled to stop working. At this time, the profile is clamped between the inner support plate 65 and the movable mounting seat 11 and the inner support plate 65 and the fixed mounting seat 10. Then the second driving cylinder 24 is controlled to drive the linkage type inner fixing mechanism 5 to move downward, so that the upper clamping plate 67 moves downward to press and fix the upper wall of the profile, thereby completing the synchronous fixation of the four profiles. Then the electric heating plate 13 is started, and the electric heating plate 13 heats up and simultaneously performs heat melting on the beveled surfaces of the four profiles. After a period of time, the beveled surfaces of the four profiles are fully melted. At this time, the electric heating plate 13 is controlled to stop working, and the first driving cylinder 12 is driven to extend, thereby driving the electric heating plate 13 from the fixed mounting seat 10 and The first motor 53 and the second motor 54 are then started again to drive the two-way screw rod 20 to rotate. The two-way screw rod 20 drives the two symmetrically arranged mounting slides 9 to approach each other, thereby driving the chamfered surface of the profile above the fixed mounting seat 10 and the chamfered surface of the profile above the movable mounting seat 11 to be close and spliced ​​together. The four profiles are close and spliced ​​together at the same time to ensure that the force is more uniform. After cooling and forming at the window frame interface, the first motor 53 and the second motor 54 are controlled to reverse, thereby driving the four installation hot melt components 8 away from the molding window frame, and then the clamping motor 39 is controlled to reverse, so that the four inner support clamping components 61 move inward synchronously. At this time, the molding window frame automatically falls off from the four inner support clamping components 61 to complete the unloading.
