Description

Technical Field

[0001] The utility model relates to the field of plastic-steel profile production equipment, in particular to high-frequency welding equipment for plastic-steel profiles. Background Art

[0002] Plastic-steel profiles are PVC profiles used to make doors and windows. Because doors and windows made solely of PVC profiles are not strong enough, steel is usually added to the mold cavity to enhance the firmness of the doors and windows. Therefore, plastic doors and windows made by adding steel inside the profile are usually called plastic-steel doors and windows. The connection of plastic-steel profiles is mainly completed by welding.

[0003] Plastic-steel profiles are primarily welded using hot melt welding. This involves heating a hot melt plate using resistance heating, fusing two sections of plastic-steel profile together, and then joining the two sections together to form a single section. However, this hot melt welding method suffers from slow melting speeds and insensitive temperature control, resulting in poor welding results.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to improve or solve the technical problem of slow hot melt speed and low welding efficiency in the prior art of hot melt welding using a hot melt plate, the utility model provides a high-frequency welding device for plastic-steel profiles. The high-frequency welding device for plastic-steel profiles comprises: a frame, comprising a workbench and a mounting frame mounted on the workbench; a high-frequency welding structure, comprising a lifting cylinder mounted on the mounting frame and a U-shaped high-frequency welding head mounted on the lifting cylinder; a clamping structure, slidably mounted on the workbench and configured to clamp a section of profile; the clamping structure comprises a sliding plate, a reference block mounted on the sliding plate, clamping blocks arranged on both sides of the profile relative to the reference block, and a telescopic cylinder driving the clamping blocks to move closer to or away from the reference block; a driving structure, mounted on the frame and configured to drive the clamping structure to move closer to or away from the other end of the profile; the driving structure comprises a rack arranged on the sliding plate, a gear meshed with the rack, and a driving motor driving the gear to rotate.

[0006] In the utility model, a high-frequency welding device for plastic-steel profiles includes a frame, a high-frequency welding structure, a clamping structure and a driving structure. The high-frequency welding structure includes a lifting cylinder and a U-shaped high-frequency welding head. The U-shaped high-frequency welding head is mounted on the ends of two sections of profiles during welding, and can quickly and evenly heat-melt the profiles. The clamping structure can be slidably installed on the workbench, and is used to drive a section of profile to move back and forth; during heat melting, the clamping structure drives a section of profile to move, so that the two sections of profile are arranged at intervals, thereby better heat melting the profile; during welding, the clamping structure drives the section of profile to dock, thereby realizing the welding of the two sections of profile. The driving structure includes a rack, a gear and a driving motor, and the driving motor drives the clamping structure to move, thereby driving the profile to move. Through the above-mentioned settings, the utility model provides a high-frequency welding device for plastic-steel profiles, which can quickly and evenly heat-melt the profiles by setting a high-frequency welding structure, a clamping structure and a driving structure, thereby improving the welding efficiency of the plastic-steel profiles; at the same time, the clamping structure and the driving structure can drive the profiles to move, thereby better heat-melting and welding the profiles.

[0007] Furthermore, a base is provided under the workbench; a avoidance groove matching the U-shaped high-frequency welding head is provided on the workbench, and a lifting plate matching the avoidance groove is arranged in the base so as to be liftable; the drive motor is installed in the base.

[0012] Furthermore, it also includes a support frame, which is arranged on both sides of the frame, and the upper side of the support frame is flush with the upper side of the workbench.

[0013] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0014] The high-frequency welding structure includes a lifting cylinder and a U-shaped high-frequency welding head. The U-shaped high-frequency welding head is mounted on the ends of two sections of profile during welding, enabling rapid and uniform heat-melting of the profiles. The clamping structure is slidably mounted on the workbench and is used to move a section of profile back and forth.

[0023] Figure 1 This is a schematic diagram of an embodiment of a high-frequency welding device for plastic-steel profiles of the present invention. Figure 1 As shown, the utility model provides a high-frequency welding device for plastic-steel profiles, which includes a frame 1, a high-frequency welding structure 2, a clamping structure 3 and a driving structure 4.

[0024] Continue to see Figure 1In one or more embodiments, the frame 1 includes a base 11, a workbench 12, and a mounting frame 13. The workbench 12 is mounted on the base 11, and the mounting frame 13 is mounted on the workbench 12. Specifically, the base 11 is in the shape of a roughly rectangular box, and its top is closed by the workbench 12. The mounting frame 13 includes a connecting plate 131 arranged on the inner side of the workbench 12 and a mounting plate 132 arranged parallel to the workbench 12. The high-frequency welding structure 2 is mounted on the mounting plate 132. Furthermore, an upper pressing plate 14 is arranged on the mounting plate 132 so as to be liftable. The upper pressing plate 14 is mounted on the mounting plate 132 by a cylinder and is used to fix the profile during profile welding. Furthermore, support frames 15 for supporting the profile are provided on both sides of the frame 1. The support frames 15 include a support plate and a support rod arranged below the support plate. The upper side of the support plate is flush with the upper side of the workbench 12.

[0025] Figure 2 This is a schematic diagram of the clamping structure and driving structure of a high-frequency welding device for plastic steel profiles of the present invention. Figure 1 and Figure 2 As shown, in one or more embodiments, the workbench 12 is in the shape of a roughly rectangular plate, and a sliding groove 121 for installing the clamping structure 3 is provided on the workbench 12, and the sliding groove 121 is in the shape of a roughly rectangular blind groove. Furthermore, a through groove 122 of the workbench 12 is provided below the sliding groove 121, and the through groove 122 is connected to the sliding groove 121. The through groove 122 is in the shape of a roughly long strip. Furthermore, a guide rail is provided in the sliding groove 121, and there are two guide rails, which are arranged side by side. Specifically, the two guide rails extend in the left and right directions. Furthermore, an avoidance groove 123 is provided on the workbench 12 to facilitate the high-frequency welding structure 2 to perform hot melting on the profile. Furthermore, a lifting plate 124 matching the avoidance groove 123 is provided in the base 11, and the lifting plate 124 is installed in the base 11 through a cylinder. When the two sections of the profile are hot-melted, the lifting plate 124 descends into the base 11 to facilitate the hot-melting of the two sections of the profile; when the two sections of the profile are hot-melted, the lifting plate 124 rises and is flush with the workbench 12, thereby facilitating the docking of the two sections of the profile. Further, a positioning block is provided on the workbench 12 for positioning the plastic-steel profile.

[0026] Continue to see Figure 1 and Figure 2In one or more embodiments, the high-frequency welding structure 2 includes a lifting cylinder 21 mounted on the mounting frame 13, and a U-shaped high-frequency welding head 22 mounted on the lifting cylinder 21. The lifting cylinder 21 is mounted on the mounting plate 132, thereby driving the U-shaped high-frequency welding head 22 to move closer to or away from the workbench 12. By energizing the U-shaped high-frequency welding head 22, a high-frequency electromagnetic field is formed, causing friction between the molecules of the plastic-steel profile, thereby generating heat and forming a molten state. Furthermore, the U-shaped high-frequency welding head 22 is matched with the avoidance groove 123, so that the end of the U-shaped high-frequency welding head 22 away from the lifting cylinder 21 can be extended into the avoidance groove 123, thereby enhancing the melting speed and melting effect of the plastic-steel profile.

[0027] Continue to see Figure 1 and Figure 2 In one or more embodiments, the clamping structure 3 includes a sliding plate 31 that matches the sliding groove 121, a reference block 32 installed on the sliding plate 31, a clamping block 33 arranged opposite to the reference block 32, and a telescopic cylinder 34 that drives the clamping block 33 to move closer to or away from the reference block 32. Specifically, the sliding plate 31 is in the shape of a roughly rectangular plate, and the top surface of the sliding plate 31 is flush with the table surface of the workbench 12. Furthermore, a guide groove that matches the guide rail is provided on the sliding plate 31, and there are two guide grooves to limit the sliding direction of the sliding plate 31. Furthermore, the reference block 32 is fixed on the sliding plate 31 for positioning the profile. The clamping block 33 is connected to the telescopic cylinder 34, which is fixed on the sliding plate 31 and drives the clamping block 33 to move closer to or away from the reference block 32 through the telescopic cylinder 34. Furthermore, a rubber pad 35 is provided on a side of the clamping block 33 close to the profile, and the rubber pad 35 prevents the clamping block 33 from damaging the profile.

The driving motor 43 is mounted in the base 11 and is fixedly connected to the base 11 through the motor frame 1. Alternatively, the driving motor 43 can be directly mounted on the workbench 12. Specifically, the rack 41 matches the through-groove 122 and is arranged in the through-groove 122, and the gear 42 extends into the through-groove 122 and meshes with the rack 41.

[0029] The working principle of the present utility model is as follows: the staff places two sections of profiles on the workbench 12, and the ends of the two sections of profiles are against each other; the upper pressure plate 14 presses down to fix the left profile on the workbench 12, and the telescopic cylinder 34 pushes the clamping block 33 to move toward the reference block 32 to fix the right profile; then the driving motor 43 rotates, driving the gear 42 to rotate, and then driving the rack 41 to move, and then the sliding plate 31 moves to the right, and the left profile and the right profile are spaced apart; the lifting cylinder 21 drives the U-shaped high-frequency welding head 22 to move downward, and hot-melt the two sections of profile. After hot-melt for 3-10 seconds, the U-shaped high-frequency welding head 22 rises and resets; finally, the driving motor 43 reverses, drives the sliding plate 31 to move to the left, and the left profile and the right profile are docked, and waits for 30-90 seconds to complete the welding.
