Description

Technical Field

[0001] The invention relates to the technical field of corner extrusion machines, and in particular to a corner extrusion machine for processing thermally broken aluminum windows. Background Art

[0002] The corner extrusion machine is a special equipment for the production of high-end thermal insulation aluminum alloy doors and windows. It is suitable for 90-degree connection of corner code structure aluminum doors and windows. The corner assembly slide is pushed by the corner assembly cylinder, and the corner assembly slide moves forward, pushing the left and right riveting shafts at the same time. The corner assembly knife on the riveting shaft realizes the 90-degree connection of aluminum doors and windows. Thermal insulation aluminum is also called thermal insulation aluminum profile, which has better performance than ordinary aluminum alloy profiles.

[0003] In the prior art, the thickness of the corner extrusion cutter of the common corner extrusion machine is fixed, and the thickness of the cutter cannot be automatically adjusted according to the thickness of the door and window profiles. The quality of the product cannot be guaranteed after the corner extrusion for the thermally broken aluminum profiles with different wall thicknesses. If the cutter thickness is thin, the extrusion force applied during the corner extrusion may be relatively concentrated on a smaller contact area, which may cause excessive local stress on the profile surface, and easily cause damage to the profile surface, such as indentations, cracks, etc., affecting the firmness of the corner extrusion. At the same time, if the cutter is too thick, the extrusion force may be excessively dispersed, and it may not provide enough force to tightly connect the corner code and the profile, which will also reduce the strength of the corner extrusion. How to invent a thermally broken aluminum window processing corner extrusion machine to solve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a thermally-insulated aluminum window processing corner extrusion machine, which aims to solve the problem that the thickness of the corner extrusion machine tool cannot be flexibly adjusted at the current stage.

[0005] The present invention is achieved in that: The present invention provides a corner extrusion machine for processing broken bridge aluminum windows, comprising a base and a corner extrusion assembly arranged on the base, wherein the upper side of the base is respectively provided with a mounting groove and a symmetrical adjustment groove, a support seat is installed on one side of the base, a clamping block is installed on one side of the support seat, a double-headed screw is installed on the inner wall of the adjustment groove, two mutually symmetrical side cutters are installed on the adjustment groove, a motor is installed on the outer wall of one side of the base, and an adjustment seat is installed on the upper side of the base close to the clamping block; The corner pressing assembly is installed above the base close to the mounting groove, and the corner pressing assembly includes a fixing frame, a fixing cutter head and an adjusting cutter head.

[0006] Preferably, the outer walls on both sides of the support seat are fixedly connected to the outer walls of the clamping block and the base respectively, the outer wall of the double-headed screw is rotatably connected to the inner wall of the adjustment groove, and the lower end of the side knife is equipped with an adjustment block slidingly connected to the inner wall of the adjustment groove, and the inner wall of the adjustment block is threadedly connected to the outer wall of the double-headed screw.

[0007] Preferably, the output end of the motor is fixedly connected to one end of the double-headed screw, and the lower end of the adjustment seat is provided with a screw threadedly connected to the inner wall of the base.

[0010] By adopting the above technical scheme, when the broken bridge aluminum window is subjected to the corner extrusion processing, the corner code is inserted between the two aluminum window frames respectively, and then the adjusting seat is rotated according to the thickness of the frame, so that the height thereof is changed under the action of the screw rod, so that the frame placed on the adjusting seat is located at the center position of the clamping block, and at the same time, the rotating shaft is rotated by the knob according to the thickness of the frame to rotate the adjusting rod. During the rotation process, the adjusting rod first contacts the adjusting blade head close to the fixed blade head, and the two ends of the adjusting rod respectively contact the inclined grooves on the upper and lower adjusting blade heads, and the inclined grooves are squeezed to slide during the rotation process, thereby squeezing the adjusting blade head to stretch the compression spring to make it Slide it outward so that one end of it is coplanar with the fixed cutter head, thereby changing the contact surface with the aluminum window frame during subsequent extrusion. Avoid a thin tool thickness. The extrusion force applied during corner extrusion may be relatively concentrated on a smaller contact area, which may lead to excessive local stress on the profile surface, easily causing damage to the profile surface, such as indentations, cracks, etc., affecting the firmness of the corner extrusion. At the same time, avoid a tool that is too thick and exerts excessive pressure on the profile during the corner extrusion process, causing unnecessary deformation of the internal structure of the profile, and even affecting the mechanical properties of the profile, so as to improve the connection strength and quality of the aluminum window frame after corner extrusion.

[0013] Preferably, the outer walls of the plurality of sliding rods are slidably connected to an adjustment frame, and a handle is fixedly connected to an outer wall of one side of the adjustment frame.

[0014] By adopting the above technical solution, when part of the adjusting cutter head is squeezed and extended outward, the positioning block contracted in the positioning groove releases the contact with the side wall of the adjusting cutter head, and under the action of the tension spring, it quickly extends into the fixed frame, so that the side wall slides along the adjusting cutter head, thereby limiting the end of the adjusting cutter head, ensuring the stable position of the adjusting cutter head, and effectively avoiding the adjusting cutter head from being subjected to excessive pressure and moving into the fixed frame during subsequent angle squeezing, avoiding too little pressure between the adjusting cutter head and the profile, thereby ensuring the effect of angle squeezing, ensuring that the aluminum window profiles can be stably fixed and connected together, and further improving the quality of the product.

[0015] The beneficial effects of the present invention are: The tool with adjustable contact area is set to avoid the tool thickness being too thin. The extrusion force applied during the corner extrusion may be relatively concentrated on a smaller contact area, which may cause excessive local stress on the profile surface, easily causing damage to the profile surface, such as indentation, cracking, etc., affecting the firmness of the corner extrusion. At the same time, avoid the tool being too thick to apply excessive pressure on the profile during the corner extrusion process, resulting in unnecessary deformation of the internal structure of the profile, and even affecting the mechanical properties of the profile, thereby improving the connection strength and quality of the aluminum window frame after corner extrusion; At the same time, the limit assembly is provided to support the adjusting knife head to ensure the stable position of the adjusting knife head, effectively preventing the adjusting knife head from moving into the fixed frame due to excessive pressure during subsequent corner extrusion, and preventing the pressure between the adjusting knife head and the profile from being too small, thereby ensuring the effect of corner extrusion and ensuring that the aluminum window profiles can be stably fixed together, further improving the quality of the product.

[0022] It should be noted that: when the broken bridge aluminum window is subjected to the corner extrusion processing, the corner code is inserted between the two aluminum window frames respectively, and then the adjusting seat 3 is rotated according to the thickness of the frame, so that the height thereof is changed under the action of the screw 31, so that the frame placed on the adjusting seat 3 is located at the center position of the clamping block 121, and at the same time, the rotating shaft 45 is rotated by the knob 452 according to the thickness of the frame to rotate the adjusting rod 451, and the adjusting rod 451 first contacts the adjusting blade 43 close to the fixed blade 42 during the rotation process, and the two ends of the adjusting rod 451 contact the inclined grooves 433 on the upper and lower adjusting blades 43 respectively, and the inclined grooves 433 are squeezed to slide during the rotation process, thereby squeezing the adjusting blade 431. The cutter head 43 stretches the compression spring 432 to make it slide outward so that one end of it is coplanar with the fixed cutter head 42, thereby changing the contact surface with the aluminum window frame during subsequent extrusion, and avoiding the cutter thickness being too thin. The extrusion force applied during corner extrusion may be relatively concentrated on a smaller contact area, which may cause excessive local stress on the profile surface, easily causing damage to the profile surface, such as indentations, cracks, etc., affecting the firmness of the corner extrusion. At the same time, avoid the cutter being too thick and applying excessive pressure on the profile during the corner extrusion process, causing unnecessary deformation of the internal structure of the profile, and even affecting the mechanical properties of the profile, thereby improving the connection strength and quality of the aluminum window frame after corner extrusion.

[0023] Furthermore, the side wall of the fixed frame 4 is provided with two sets of upper and lower positioning grooves 411, the inner wall of the positioning groove 411 is slidably connected with a positioning block 5, one end of the positioning block 5 is provided with a fixing groove 51, the inner wall of the fixing groove 51 is fixedly connected with a tension spring 52, the inner wall of the tension spring 52 is sleeved with a sliding rod 53 fixedly connected to the inner wall of the fixing groove 51, the outer wall of the sliding rod 53 is slidably connected to the inner wall of the positioning groove 411, one end of the sliding rod 53 passing through the fixed frame 4 is fixedly connected with a stopper 531, the outer walls of the plurality of sliding rods 53 are slidably connected with an adjusting frame 54, and the outer wall of one side of the adjusting frame 54 is fixedly connected with a handle 55.

[0024] It should be noted that: when part of the adjusting knife head 43 is squeezed and extended outward, the positioning block 5 contracted in the positioning groove 411 releases the contact with the side wall of the adjusting knife head 43, and under the action of the tension spring 52, it quickly extends into the fixed frame 4, so that the side wall of the adjusting knife head 43 slides along the adjusting knife head 43, thereby limiting the end of the adjusting knife head 43, ensuring the stability of the position of the adjusting knife head 43, and effectively avoiding the adjusting knife head 43 from being subjected to excessive pressure and moving into the fixed frame 4 during subsequent corner squeezing, avoiding too little pressure between the adjusting knife head 43 and the profile, thereby ensuring the effect of corner squeezing, ensuring that the aluminum window profiles can be stably fixed and connected together, and further improving the quality of the product.

[0025] The working principle of this kind of broken bridge aluminum window processing corner extrusion machine: When the insulated aluminum window is subjected to the corner extrusion processing, the angle code is inserted between the two aluminum window frames respectively, and then the adjusting seat 3 is rotated according to the thickness of the frame, so that the height thereof is changed under the action of the screw 31, so that the frame placed on the adjusting seat 3 is located at the center position of the clamping block 121, and at the same time, the rotating shaft 45 is rotated by the knob 452 according to the thickness of the frame to rotate the adjusting rod 451, and the adjusting rod 451 first contacts the adjusting blade 43 close to the fixed blade 42 during the rotation process, and its two ends contact the inclined grooves 433 on the upper and lower adjusting blades 43 respectively, and squeezes the inclined grooves 433 to slide during the rotation process, thereby squeezing the adjusting blade 43 to stretch the compression spring 432 to slide outward, so that one end of the adjusting blade is coplanar with the fixed blade 42, thereby changing the contact between the adjusting blade 43 and the aluminum window frame during the subsequent extrusion. The contact surface of the frame is then started, and the hydraulic rod 15 and the motor 14 are started, so that the corner extrusion assembly presses the aluminum window frame against the side wall of the clamping block 121, and at the same time, the side knives 2 on both sides move toward each other at the same time to extrude and connect the frames on both sides from the side, thereby realizing the corner extrusion of the aluminum window. By setting a tool with an adjustable contact area, the thickness of the tool is avoided to be thin. The extrusion force applied during the corner extrusion may be relatively concentrated on a smaller contact area, which may cause excessive local stress on the surface of the profile, easily causing damage to the surface of the profile, such as indentation, cracking, etc., affecting the firmness of the corner extrusion. At the same time, avoid the tool being too thick to apply excessive pressure on the profile during the corner extrusion process, resulting in unnecessary deformation of the internal structure of the profile, and even affecting the mechanical properties of the profile, thereby improving the connection strength and quality of the aluminum window frame after the corner extrusion.
