Technical Field
[0001] The invention relates to the technical field of aluminum profile processing equipment, and in particular to a multifunctional adjustable punching device for aluminum profile processing. Background Art
[0002] Aluminum profile door and window frames are commonly fastened together using angle brackets. Before installing the angle brackets, holes must be drilled into the ends of the two connecting aluminum profiles. These holes include both the angle bracket mounting holes and the glue injection holes. The diameter of the glue injection holes is generally smaller than the mounting holes, and the glue injection holes only need to be drilled into the end of one of the profiles.

DETAILED DESCRIPTION
[0017] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.
[0018] like Figures 1 to 23As shown in the figure, a multifunctional adjustable punching device for aluminum profile processing comprises a top plate 1 and a bottom plate 2 arranged opposite to each other in an upper and lower direction, wherein the four corners of the upper surface of the bottom plate 2 are fixedly mounted with guide posts 201, and the guide posts 201 are sleeved with return springs 202. The four corners of the top plate 1 are provided with shaft sleeves 101 for sliding cooperation with the guide posts 201, and a pull rod device is installed between the two sides of the top plate 1 and the bottom plate 2, and the pull rod device is used to overcome the elastic potential energy of the return spring 202 to limit the top end of the guide post 201 in the shaft sleeve 101; the lower surface of the top plate 1 is provided with an upper slide rail 104 extending in the left and right directions, and the upper slide rail 104 is provided An upper adjustment seat 105 is slidably mounted on the rail 104, and a punch adjustment seat 106 is mounted on the upper adjustment seat 105. A glue injection hole punch 108 and a rivet hole punch 109 arranged front and back are mounted on the punch adjustment seat 106. The punch adjustment seat 106 is used to adjust whether the glue injection hole punch 108 is working; a lower sliding rail 203 extending in the left and right directions is mounted on the upper surface of the bottom plate 2, and a lower adjustment seat 204 is slidably mounted on the lower sliding rail 203, and a clamp adjustment seat 205 is mounted on the lower adjustment seat 204. A profile clamp 206 is mounted on the clamp adjustment seat 205, and a glue injection clamp 206 is vertically penetrated through the profile clamp 206. Punching needle punching 2064 and riveting needle punching 2065, when punching, ensure that the injection punching needle punching 2064 is coaxial with the injection hole punching needle 108, and the riveting punching needle punching 2065 is coaxial with the riveting hole punching needle 109, and the rear end of the clamp adjustment seat 205 is installed with a profile limiting device 207; the bottom plate 2 is also installed with a limiting support plate 4 for limiting the downward displacement limit of the top plate 1; when it is necessary to punch a hole in the aluminum profile, first adjust the left and right position of the lower adjustment seat 204 so that it slides left and right on the lower rail 203 to match the width of the aluminum profile, and then insert the aluminum profile horizontally into the profile clamp 206, Adjust the profile limit device 207 to control the front and rear distance of the aluminum profile insertion, then adjust the upper adjustment seat 105 to the position corresponding to the lower adjustment seat 204, adjust the punch needle adjustment seat 106, ensure that the glue injection punch needle punching 2064 is coaxial with the glue injection hole punch needle 108, and the rivet punch needle punching 2065 is coaxial with the rivet hole punch needle 109, and the hydraulic cylinder applies downward pressure to the top plate 1. The top plate 1 overcomes the elastic force of the reset spring 202 and moves downward along the guide column 201 until it conflicts with the limit support plate 4. The glue injection hole punch needle 108 and the rivet hole punch needle 109 now complete the punching of the aluminum profile. After the punching is completed, the hydraulic cylinder is retracted, and the top plate 1 is reset upward under the elastic force of the reset spring 202 until the pull rod device limits it to the initial position to ensure that the top plate 1 does not separate from the guide column 201.The present invention can not only adapt to aluminum profiles of different widths by adjusting the left and right positions of the upper adjustment seat 105 and the lower adjustment seat 204, but also adjust the profile limit device 207 to control the front and rear distance of the aluminum profile punching. The front and rear positions of the clamp adjustment seat 205 and the punch needle adjustment seat 106 can also be adjusted according to the use requirements, thus achieving multi-dimensional adjustability. Moreover, when the aluminum profile only needs to punch one angle bracket installation hole, the injection hole punch needle 108 can be determined to be inoperative by adjusting the punch needle adjustment seat 106. The present invention has a simple structure, a small footprint, convenient adjustment, and convenient operation, and can well meet the punching requirements of different aluminum profiles and different angle brackets.
[0019] like Figure 3 、 Figure 4 and Figure 5 As shown in common, both ends of the top plate 1 are provided with tie rod mounting stepped holes 102, and the upper aperture of the tie rod mounting stepped holes 102 is larger than the lower aperture; the tie rod device includes a tie rod 3 threadedly mounted on the bottom plate 2, and a fixing nut 301 is threadedly mounted on the top of the tie rod 3. The top end of the tie rod 3 passes through the top plate 1 and the fixing nut 301 is located in the tie rod mounting stepped hole 102. The outer diameter of the tie rod 3 is smaller than the lower aperture of the tie rod mounting stepped hole 102, so the top plate 1 can slide downward along the tie rod 3, but when the top plate 1 slides upward, due to the presence of the fixing nut 301, the outer diameter of the fixing nut 301 is larger than the lower aperture, so the tie rod 3 cannot be separated from the top plate 1, ensuring that the top end of the guide column 201 is always located in the shaft sleeve 101.
[0020] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9As shown together, a row of threaded blind holes 103 are respectively provided on the lower surface of the top plate 1 and the upper surface of the bottom plate 2, and a plurality of slide rail mounting countersunk holes 1041 are respectively provided on the upper slide rail 104 and the lower slide rail 203 corresponding to the threaded blind holes 103. The upper slide rail 104 and the lower slide rail 203 are respectively fixedly mounted on the top plate 1 and the bottom plate 2 by countersunk bolts; the upper slide rail 104 includes a vertical limiting surface 1042 and an inclined limiting surface 1043, and a limiting seat limiting threaded hole 1051 is provided on the surface of the corresponding upper adjustment seat 105 that is in contact with the vertical limiting surface 1042, and a limiting seat limiting bolt 1052 is installed in the limiting seat limiting threaded hole 1051. The upper adjustment seat 105 is also provided with a threaded mounting blind hole 1053, and the lower slide rail 203 has the same structure as the upper slide rail 104, and the lower adjustment seat 204 has the same structure as the upper adjustment seat 105. In this embodiment, six threaded blind holes 103 are provided. Countersunk bolts penetrate the rail mounting countersunk holes 1041 and are threaded into the threaded blind holes 103, securing the upper rail 104 to the top plate 1 and the lower rail 203 to the bottom plate 2. The track of the upper rail 104 matches the shape of the notch in the upper mounting seat. The inclined limiting surface 1043 ensures that the upper adjustment seat 105 remains on the upper rail 104 and does not easily disengage. The vertical limiting surface 1042 allows the limiting seat limiting bolt 1052 to penetrate the limiting seat limiting threaded hole 1051 and secure the upper mounting seat to the upper rail 104, fixing its left and right position and preventing displacement during machining, thereby ensuring machining accuracy. The lower rail 203 has the same structure as the upper rail 104, and the lower adjustment seat 204 also has the same structure as the upper adjustment seat 105. Their structures and installation methods are not detailed here.
[0021] like Figures 11 to 20 As shown in common, the punch needle adjustment seat 106 is a rectangular parallelepiped, and an upper long slot through hole 1061 is provided on one side of the punch needle adjustment seat 106, and a riveting punch needle mounting hole 1063, a circular adjustment blind hole 1064 and a semicircular punch needle avoidance hole 1068 are sequentially spaced apart on the other side of the punch needle adjustment seat 106. The circular adjustment blind hole 1064 intersects with the semicircular punch needle avoidance hole 1068 and the two have the same depth. The center of the semicircular punch needle avoidance hole 1068 is located in the circular adjustment blind hole 1064, and the bottom of the semicircular punch needle avoidance hole 1068 extends downward to form a glue injection punch needle mounting hole 1062; the outer peripheral surface of the circular adjustment blind hole 1064 extends out of the side of the punch needle adjustment seat 106 and is provided with an adjustment opening 1065, the center of the circular adjustment blind hole 1064 is fixedly installed with a rotating shaft 1066, and the outer peripheral surface of the circular adjustment blind hole 1064 is fixedly installed with a limiting shaft 1067.
[0022] like Figure 15 、 Figure 16 、 Figures 17 to 20As shown in common, a cylindrical adjustment block 107 is rotatably installed in the circular adjustment blind hole 1064, and a rotating hole 1071 that rotates around the rotating shaft 1066 is provided in the center of the adjustment block 107, and a limiting notch 1072 is provided on the outer circumference of the adjustment block 107 for use with the limiting shaft 1067. The limiting notch 1072 includes an open end 10721 and a closed end 10722. The outer circumference of the adjustment block 107 is also provided with a semicircular punch needle avoidance notch 1073 for use with the semicircular punch needle avoidance hole 1068. When the limiting shaft 1067 abuts against the open end 10721 of the limiting notch 1072, the glue injection hole punch needle 108 can pass through the semicircular punch needle avoidance hole 1068 and move upward. When the limiting shaft 1067 abuts against the closed end 10722 of the limiting notch 1072, the glue injection hole punch needle 108 cannot pass through the semicircular punch needle avoidance hole 1068 and move upward.
[0023] When it is necessary to punch a hole in the aluminum profile, and when only one glue injection hole is needed, the adjustment block 107 can be rotated to adjust whether the open end 10721 or the closed end 10722 of the limiting notch 1072 contacts the limiting shaft 1067. The rotating hole 1071 of the adjustment block 107 rotates around the rotating shaft 1066, and the rotation stroke is located between the open end 10721 and the closed end 10722 of the limiting notch 1072, and the rotation angle is 45°. When the open end 10721 is rotated to contact the limit shaft 1067, the semicircular punch needle avoidance hole 1068 cooperates with the semicircular punch needle avoidance notch 1073 to form a complete circular hole. The top of the injection hole punch needle 108 can pass through the circular hole and can move upward when the top plate 1 is pressed down. At this time, no injection hole is punched on the profile; when the closed end 10722 is rotated to contact the limit shaft 1067, the semicircular punch needle avoidance hole 1068 and the semicircular punch needle avoidance notch 1073 are just staggered. The top of the injection hole punch needle 108 cannot pass through the adjustment block 107 and cannot move upward when the top plate 1 is pressed down. At this time, the profile is completed. Therefore, by rotating the adjustment block 107, it is very convenient to determine whether the aluminum profile is to be punched with a glue hole. Regardless of whether the glue hole is punched or not, the rivet hole will be punched because the upper surface of the rivet hole punch needle 109 is always flush with the upper surface of the punch needle adjustment seat 106 when the hydraulic cylinder is pressed down. The upper surface of the rivet hole punch 109 rests on the upper adjustment seat 105 .
[0024] like Figure 11 and Figure 14As shown in the figure, the injection hole 1062 and the rivet hole 1063 are both stepped holes, and the tops of the injection hole punch 108 and the rivet hole punch 109 are respectively adapted to the shape of the corresponding stepped holes. The stepped holes can ensure that the injection hole punch 108 and the rivet hole punch 109 will not fall down, but can move upward. When punching, the top of the top plate 1 and the top of the rivet hole punch 109 are connected, so the rivet hole punch 109 will continue to punch holes, but whether the injection hole punch 108 can contact the top plate 1 depends on the rotation position of the punch adjustment seat 106.
[0025] Both the open end 10721 and the closed end 10722 of the limiting notch 1072 are arc-shaped notches. The diameter of the arc-shaped notch is consistent with the diameter of the limiting shaft 1067. The angle between the center of each of the open end 10721 and the closed end 10722 and the center of the rotating shaft 1066 is 45 degrees. The arc-shaped notches of the open end 10721 and the closed end 10722 are designed to mate with the outer circumference of the limiting shaft 1067. The arc-shaped surface connecting the open end 10721 and the closed end 10722 also mates with the limiting post during displacement around the limiting shaft 1067.
[0026] like Figure 13 、 Figures 17 to 20 As shown in common, the stepped hole of the glue injection needle mounting hole 1062 includes an upper glue injection hole and a lower glue injection hole. The diameter of the upper glue injection hole is larger than the diameter of the lower glue injection hole. A cylindrical boss is provided on the top of the glue injection hole punch needle 108. The diameter of the upper glue injection hole is consistent with the diameter of the cylindrical boss, and the diameter of the lower glue injection hole is consistent with the diameter of the glue injection hole punch needle 108. After the glue injection hole punch needle 108 is inserted into the glue injection needle mounting hole 1062, the cylindrical boss is stuck in the upper glue injection hole to prevent the glue injection hole punch needle 108 from falling down. Whether it can move upward depends on the rotation direction of the adjustment block 107. When the adjustment block 107 blocks the semicircular punch avoidance hole 1068, the glue injection hole punch needle 108 cannot move upward and is in a punching state.
[0027] like Figure 13 、 Figures 17 to 20 As shown in the figure, the diameter of the semicircular punch needle avoidance hole 1068 is larger than the diameter of the glue injection hole, and the diameter of the semicircular punch needle avoidance hole 1068 is equal to the diameter of the semicircular punch needle avoidance notch 1073. When the limiting shaft 1067 abuts the open end 10721 of the limiting notch 1072, the semicircular punch needle avoidance notch 1073 is coaxial with the semicircular punch needle avoidance hole 1068. The diameter of the semicircular punch needle avoidance hole 1068 is larger than the diameter of the glue injection hole to facilitate the installation of the glue injection hole punch needle 108. When the limiting shaft 1067 abuts the open end 10721 of the limiting notch 1072, the glue injection hole punch needle 108 has sufficient avoidance space and moves upward to avoid, and is in a non-punching state.
[0028] like Figure 13 、 Figures 17 to 20 As shown together, the stepped hole of the rivet punch mounting hole 1063 includes an upper rivet hole and a lower rivet hole. The diameter of the upper rivet hole is larger than that of the lower rivet hole. A cylindrical boss is provided on the top of the rivet hole punch 109. The diameter of the upper rivet hole is consistent with the diameter of the cylindrical boss, the depth of the upper rivet hole is consistent with the height of the cylindrical boss, and the diameter of the lower rivet hole is consistent with the diameter of the rivet hole punch 109. When the punch adjustment seat 106 is installed, its upper surface is in conflict with the upper adjustment seat 105. Therefore, the rivet hole punch 109 will not move upward during punching, and the punching is completed.
[0029] like Figure 12 As shown, there are two upper slotted through holes 1061. The two upper slotted through holes 1061 are of the same size, and their center lines are located on the same straight line. The upper slotted through holes 1061 are used in conjunction with the threaded mounting blind holes on the upper adjustment seat 105 to adjust the front-to-back position of the punch adjustment seat 106 to meet the processing requirements of different profiles. The upper slotted through holes 1061 are located on the same straight line to facilitate bidirectional adjustment. When two adjacent punch adjustment seats 106 are displaced forward and backward, the distance between the two upper slotted through holes 1061 can be staggered.
[0030] like Figures 1 to 4 As shown together, the height of the rotating shaft 1066 and the limiting shaft 1067 is consistent with the depth of the circular adjustment blind hole 1064. In this way, the rotating shaft 1066 and the limiting shaft 1067 will not protrude from the outer surface of the punch needle adjustment seat 106, and will not interfere during installation.
[0031] like Figure 16 、 Figures 17 to 20 As shown, the thickness of the adjustment block 107 is consistent with the depth of the circular adjustment blind hole 1064. This is so that when the limiting shaft 1067 abuts the closed end 10722 of the limiting notch 1072, the top of the injection hole punch 108 is the adjustment block 107. If the thickness of the adjustment block 107 is less than the depth of the circular adjustment blind hole 1064, then when the hydraulic cylinder is pressed down, the injection hole punch 108 will move upward against the adjustment block 107, and the punching function will not be achieved. Therefore, the thickness of the adjustment block 107 must be consistent with the depth of the circular adjustment blind hole 1064 to achieve normal punching. The side of the adjustment block 107 can be provided with small ridges to prevent slipping when it is moved.
[0032] like Figure 10As shown, the clamp adjustment base 205 is a rectangular parallelepiped, with a lower slotted through hole 2052 defined on one side of the clamp adjustment base 205, and a clamp mounting countersunk hole 2051 defined on the other side for mounting the clamp adjustment base 205. The lower slotted through hole 2052 is designed to cooperate with the threaded mounting blind hole 1053 on the lower adjustment base 204, allowing the front and rear positions of the clamp adjustment base 205 to adapt to the processing requirements of different profiles.
[0033] like Figures 18 to 20 As shown, the profile fixture 206 includes an upper clamping plate 2061 and a lower clamping plate 2062 integrally arranged above and below. A horizontal gap 2063 for placing the aluminum profile is defined between the front ends of the upper clamping plate 2061 and the lower clamping plate 2062. The height of the aluminum profile placement gap 2063 is greater than the thickness of the aluminum profile. The injection needle punching hole 2064 is coaxial with the injection needle mounting hole 1062, and the rivet needle punching hole 2065 is coaxial with the rivet needle mounting hole 1063. The height of the aluminum profile placement gap 2063 is slightly greater than the thickness of the aluminum profile. As long as the aluminum profile can be inserted, the injection needle punching hole 2064 is coaxial with the injection needle mounting hole 1062, and the rivet needle punching hole 2065 is coaxial with the rivet needle mounting hole 1063. This ensures accuracy during punching.
[0034] like Figures 18 to 20 As shown together, the profile limiting device 207 includes a horizontal threaded hole horizontally passing through the front and rear ends of the profile clamp 206, and a profile limiting screw 2072 is installed in the horizontal threaded hole. The front end of the profile limiting screw 2072 extends into the aluminum profile placement gap 2063, and the rear end of the profile limiting screw 2072 is located outside the profile clamp 206 and is provided with an adjustment handle 2073; a vertical threaded hole 2074 extending to the horizontal threaded hole is opened on the upper clamp 2061, and a fastening bolt 2071 for fixing the profile limiting screw 2072 is installed in the vertical threaded hole 2074. After the aluminum profile is inserted into the aluminum profile placement gap 2063, it is positioned against the end of the profile limiting screw 2072 to control the distance between the punching position and the end of the aluminum profile. By rotating the adjusting handle 2073, the extension length of the profile limiting screw 2072 can be adjusted. After adjusting the position of the profile limiting screw 2072, the fastening bolt 2071 is inserted into the vertical threaded hole 2074 and tightened until the end of the fastening bolt 2071 is against the profile limiting screw 2072 to fix the profile limiting screw 2072.
[0035] like Figures 1 to 4As shown in the figure, the base plate 2 is also equipped with a fixed plate 5 and a movable plate 6 for fixing the aluminum profile. The fixed plate 5 and the movable plate 6 are respectively equipped with a rubber protective plate 7. A locking device is installed between the movable plate 6 and the base plate 2. The locking device can adopt a conventional lock in the prior art. It only needs to be able to fix the position of the movable plate 6 relative to the base plate 2. There is no special limitation on its installation position. As long as it does not cause interference, it is all prior art and will not be described here. The fixed plate 5 is fixedly installed in the center of the base plate 2, and the movable plates 6 are symmetrically slidably installed on both sides. First, after inserting the aluminum profile into the aluminum profile placement gap 2063, one end of it is against one side of the fixed plate 5, and then the movable plate 6 is moved to rest against the other side of the aluminum profile. Then the locking device fixes the position of the movable plate 6 before the position adjustment of other components is carried out. The rubber protective plate 7 can protect the aluminum profile from wear during processing.
[0036] The use process of the present invention is as follows: Before installing the angle bracket, it is necessary to punch holes at the ends of the two aluminum profiles to be connected, including the angle bracket installation holes and the glue injection holes. Since the holes of the two aluminum profiles to be connected are mirror images, a pair of mirror-image punching devices are preferably installed between the top plate 1 and the bottom plate 2. In this embodiment, Figures 1 to 4 As shown, a pair of punching devices are installed for simultaneously punching two aluminum profiles that need to be spliced together. This can improve processing efficiency. Of course, in order to further improve processing efficiency, more than two pairs can be installed. The present invention is described by taking the installation of one pair as an example.
[0037] The pair of punching devices on the left includes two profile clamps 206, which are used to clamp the A side and B side of the aluminum profile respectively. The pair of punching devices on the right also includes two profile clamps 206, which are used to clamp the B side and A side of the aluminum profile respectively. The holes punched on both sides are mirror images and can be directly used to install angle brackets.
[0038] Before punching, first adjust the spacing of the lower adjustment seat 204 according to the width of the aluminum profile to match the width of the profile, then insert the aluminum profile into the aluminum profile placement gap 2063, and make one end of the aluminum profile rest on the fixed plate 5. At this time, adjust the profile limit screw 2072 to control the depth of the aluminum profile, tighten the fastening bolt 2071, and then move the movable plate 6 to make it rest against the other end of the aluminum profile. Adjust the upper adjustment seat 105 so that it is opposite to the lower adjustment seat 204 in the upper and lower directions, and adjust the adjustment block 107 of the punch needle adjustment seat 106. The rotation position of the adjustment block 107 is determined according to whether the profile needs to have a glue hole. Generally, only one of the two butted aluminum profiles needs to have a glue hole, and both riveted holes need to be punched. In this embodiment, the left profile is punched with a glue hole and the right profile is not punched with a glue hole as an example. Control the left adjustment block 107 to rotate to Figure 19 and Figure 20The state controls the right adjustment block 107 to rotate to Figure 17 and Figure 18 state, so that when the hydraulic cylinder applies pressure to the top plate 1, the semicircular punch needle avoidance notch 1073 on the left rotates to the outside of the semicircular punch needle avoidance hole 1068, and the adjustment block 107 partially blocks the glue injection punch needle mounting hole 1062, and the glue injection hole punch needle 108 cannot move upward. When the top plate 1 is pressed down, the glue injection hole punch needle 108 cannot move upward under the blocking effect of the adjustment block 107, and will contact the aluminum profile to complete the glue injection hole. The adjustment block 107 on the right fails to block the glue injection needle mounting hole 1062, and the glue injection hole punch needle 108 can move upward; when the top plate 1 is pressed down, the glue injection hole punch needle 108 passes through the semicircular punch needle avoidance hole 1068 and moves upward, and will not contact the aluminum profile, and will not make a glue hole. Of course, according to usage requirements, the glue hole on the right can be made and the glue hole on the left cannot be made, or glue holes can be made on both sides at the same time. The upper surface of the rivet hole punch 109 is always in conflict with the lower surface of the upper adjustment seat 105, so the rivet hole punch 109 will not move upward when punching, and the punching will be completed.
[0039] The present invention can not only adapt to aluminum profiles of different widths by adjusting the left and right positions of the upper adjustment seat 105 and the lower adjustment seat 204, but also adjust the profile limit device 207 to control the front and rear distance of the aluminum profile punching. The front and rear positions of the clamp adjustment seat 205 and the punch needle adjustment seat 106 can also be adjusted according to the use requirements, thus achieving multi-dimensional adjustability. Moreover, when the aluminum profile only needs to punch one angle bracket installation hole, the injection hole punch needle 108 can be determined to be in operation by adjusting the punch needle adjustment seat 106. The present invention has a simple structure, a small footprint, convenient adjustment, and convenient operation, and can well meet the punching requirements of different aluminum profiles and different angle brackets.
