[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only for reference to the orientation of the drawings. The directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0043] The terms "first", "second", etc. in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, the connection may be a detachable connection or a connection of an integral structure; it may be a direct connection or an indirect connection through an intermediate medium.

[0046] In addition, when the profile punching device in the prior art punches holes in a longer profile, since the support rod also needs to be set to a longer length, the suspended end of the support rod is easily close to the punching work plane due to its own weight, making it inconvenient to insert into the profile.

[0047] The following is a first embodiment of a profile punching device provided by the present invention that can solve the above technical problems.

[0048] Please refer to Figure 1 ,in Figure 1 It is a schematic structural diagram of the first embodiment of the profile punching device of the present invention.

[0054] The first positioning member 17 is movably connected to the support guide rod 14. When the profile moves toward the direction close to the pad block 15, the first positioning member 17 contacts the profile for positioning. For shorter profiles, the profile will be positioned with the first positioning member 17 by pushing the profile, and then the punching operation is performed. At the same time, the profile can be positioned and punched multiple times by moving the position of the first positioning member 17.

[0055] Please refer to Figure 4 Optionally, the first positioning member 17 includes a sliding ring body 171 and a screw member 172. The sliding ring body 171 is a closed annular structure.

[0056] An extension piece is provided on the outer periphery of the screw member 172 , so that an operator can conveniently screw the screw member 172 .

[0057] The positioning profile 16 is detachably connected to the side of the mounting frame 11 away from the padding block 15, and the second positioning member 162 is detachably connected to the positioning profile 16. When the profile moves away from the padding block 15, the second positioning member 162 contacts the profile for positioning. For a long profile, the profile is positioned with the second positioning member 162 by pulling the profile, and then the punching operation is performed. At the same time, the profile can be positioned and punched multiple times by moving and changing the position of the second positioning member 162.

[0058] The profile punching device of the present invention can perform positioning punching by pushing the profile to contact the first positioning member 17, or pulling the profile to contact the second positioning member 162, and has high compatibility of punching positioning and low equipment use cost.

[0059] In this embodiment, a plurality of support plates 13 may be provided on the mounting frame 11, and the plurality of support plates 13 may be used to provide support guide rods 14 of different specifications, so that the sliding guide mechanism can be suitable for supporting profiles of different models and specifications, and has high compatibility for profile support and sliding guide. A frame block 12 and a punching device 18 may be provided corresponding to each support guide rod 14.

[0060] Please refer to Figure 5 A positioning groove 151 for positioning and connecting with the supporting guide rod 14 can be provided on the raising block 15 so that the supporting guide rod 14 and the raising block 15 form a stable matching connection.

[0061] Optionally, the positioning groove 151 may include a plurality of interconnected groove sections, the widths of the plurality of groove sections are different, and the width of the groove section close to the punching working plane 111 is greater than the width of the groove section away from the punching working plane 111. In this way, the positioning groove 151 can adapt to positioning support guide rods 14 of different sizes.

[0062] Please refer to Figure 2 In this embodiment, the profile punching device further includes a support wheel 1C, which is located at the bottom of one end of the support guide rod 14 away from the pad block 15. The support plate 13 is provided with a mounting hole 131. The support wheel 1C is elastically lifted and lowered in the mounting hole 131. The support wheel 1C is used to support the support guide rod 14 so that the support guide rod 14 is at a set distance from the support plate 13. The support wheel 1C can provide a certain support to the support guide rod 14 so that the support guide rod 14 and the support plate 13 are kept at a set distance. The support wheel 1C is not likely to hinder the support guide rod 14 from being inserted into the profile, and is very convenient for the support guide rod 14 to be inserted into the profile.

[0063] Please refer to Figure 2 Specifically, the support wheel 1C is rotatably mounted in the U-shaped seat 1C1, and the U-shaped seat 1C1 is slidably disposed in the mounting hole 131.

[0064] Furthermore, a fixing plate 1D is provided at the bottom of the support plate 13. The fixing plate 1D is an L-shaped structure. The fixing plate 1D includes a first plate body 1D1 and a second plate body 1D2. The first plate body 1D1 is parallel to the axial direction of the mounting hole 131, and the second plate body 1D2 is perpendicular to the axial direction of the mounting hole 131. The mounting hole 131 passes through the support plate 13. The second plate body 1D2 is located on the axial extension track of the mounting hole 131. An elastic member 1C2 is connected between the U-shaped seat 1C1 and the second plate body 1D2. The elastic member 1C2 can be used to drive the support wheel 1C to move and protrude from the top surface of the support plate 13.

[0065] The elastic member 1C2 may be a spring, and a positioning column 1D21 for positioning and connecting with the spring may be provided on the second plate body 1C2 and the U-shaped seat 1C1.

[0066] In addition, a slide groove 132 is provided on the inner wall of the mounting hole 131, and the U-shaped seat 1C1 is slidably provided in the slide groove 132. A limit block 28 is provided at one end of the slide groove 132 close to the support guide rod 14 (the top of the slide groove 132 does not penetrate the top surface of the support plate 13 to form a limit block), and the limit block 28 is used to limit the height of the support wheel 1C protruding from the top surface of the support plate 13. The height of the support wheel 1C protruding from the top surface of the support plate 13 is less than the radius of the support wheel 1C, which is conducive to the sliding descent of the profile extrusion support wheel 1C.

[0067] Please refer to Figure 3In this embodiment, the profile punching device further includes a pressing plate 1F, a positioning groove is provided on the punching work plane 111, and the frame block 12 is positioned in the positioning groove, and the positioning groove can limit the horizontal movement of the frame block 12. Pressure blocks 124 are protrudingly provided on two opposite outer sides of the frame block 12, and the pressing plate 1F is detachably fixedly connected to the punching work plane 111, and one end of the pressing plate 1F presses the pressure block 124, thereby fixing the frame block 12 in the positioning groove, and the pressing plate 1F can limit the vertical movement of the frame block 12.

[0068] A fastening threaded hole is provided on the punching work plane 111, and a fastening screw 1F1 for threaded connection with the fastening threaded hole is provided through the pressing plate 1F, and a supporting screw 1F2 is threadedly connected to the bottom surface of the pressing plate 1F, and the fastening screw 1F1 is located between the supporting screw 1F2 and the pressure block 124. By adjusting the length of the supporting screw 1F2 protruding from the pressing plate 1F by screwing, and cooperating with the fastening screw 1F1 to squeeze the pressing plate 1F, the pressing plate 1F can flexibly press the pressure block 124, and the thickness requirement of the pressure block 124 is low, and the pressing compatibility of the pressure block 124 is high.

[0069] A pressure block 124 is formed on two opposite outer sides of the frame block 12 and is provided along the axial direction of the fixing hole 121 .

[0070] The two opposite inner wall surfaces of the fixing hole 121 are provided with mounting grooves 1211, and the mounting grooves 1211 are provided with guide wheels 1E, and the circumferential wheel surface of the guide wheels 1E protrudes from the inner wall surface of the fixing hole 121. The guide wheels 1E are in contact with the side surface of the profile, which can squeeze and fix the profile, and also facilitate the profile to move in the fixing hole 121.

[0071] Among them, a guide convex edge strip 123 is provided along one end edge of the fixing hole 121 protruding in the axial direction of the fixing hole 121, and the guide convex edge strip 123 extends and protrudes along the axial direction of the fixing hole 121. The guide convex edge strip 123 can support the profile in the initial stage of inserting the profile into the fixing hole 121, so that the profile can be inserted into the fixing hole 121 more efficiently.

[0072] The guide flange strip 123 in this embodiment includes a main strip segment covering the bottom edge of one end of the fixing hole 121, and an end strip segment located at one end of the main strip segment, that is, the guide flange strip 123 is an L-shaped structure, which is convenient for quickly positioning the profile onto the guide flange strip 123.

[0073] Please refer to Figure 1In this embodiment, a connecting plate 19 is provided on the side of the mounting frame 11, and the positioning profile 16 is a profile with holes punched. Screws can be used to pass through the holes 161 on the positioning profile 16 and threadedly connected to the threaded holes on the connecting plate 19, so that the positioning profile 16 and the mounting frame 11 are fixedly connected. The profile punching device also includes a support frame 1A, one end of the positioning profile 16 is fixedly connected to the connecting plate 19, and the other end of the positioning profile 16 is located on the support frame 1A.

[0074] The second positioning member 162 is a positioning block 1621 and a plug 1622 disposed on one side of the positioning block 1621. The plug 1622 is plugged into a hole punched in the positioning profile 16. The positioning block 1621 is located on the top surface of the positioning profile 16. By positioning the positioning block 1621 with the profile, the position of the positioning block 1621 is changed, thereby changing the positioning position of the profile.

[0075] In this embodiment, a connection hole 125 may be provided through the frame block 12, a scale rod 1B may be slidably provided in the connection hole 125, a scale head 1B1 may be rotatably provided at one end of the scale rod 1B, and the scale head 1B1 may feedback the punching spacing of the profile inserted into the fixing hole 121. Rotating the scale head 1B1 upward may avoid interference with the movement of the profile, and rotating the scale head 1B1 downward to make it close to the profile to feedback the position of the profile movement, so that the profile may be punched after the profile moves by the set spacing.

[0076] Among them, an external ruler can be used to measure the extension size of the scale rod 1B relative to the frame block 12, or a scale can be directly set on the scale rod 1B, and the extension size of the scale rod 1B relative to the frame block 12 can be adjusted to provide feedback on the distance the profile moves each time. By setting the scale rod 1B, the profile punching device in this embodiment can increase the measurement and positioning methods for profile punching.

[0077] The working principle of the profile punching device of this embodiment is as follows: when punching a shorter profile, the profile can be inserted into the support guide rod 14, wherein the support wheel 1C supports the support guide rod 14 so that the support guide rod 14 can remain suspended and extend into the fixing hole 121, which facilitates the insertion of the support guide rod 14 into the profile. During the insertion of the support guide rod 14 into the profile, the profile will squeeze the support wheel 1C to move down and retract into the mounting hole 131. The support wheel 1C will not hinder the insertion of the support guide rod 14 into the profile.

[0078] After the profile is inserted into the support guide rod 14, the punching starts from the end of the profile away from the operator. The frame block 12 and the guide wheel 1E inside the frame block 12 can well position and fix the profile, and at the same time facilitate the movement of the profile. Then the position of the first positioning member 17 is adjusted, and the profile is pushed to move until it contacts the first positioning member 17 and stops, and then the punching device 18 performs a punching operation on the profile.

[0079] After completing one time of pushing the profile and punching, adjust the position of the first positioning member 17, push the profile until it contacts the first positioning member 17, and then stop the punching operation, and repeat the above operation until all the punching work is completed.

[0080] When punching a long profile, since the first positioning member 17 is located on the side of the punching device 18 away from the operator and the profile is long, it is not convenient to adjust the position of the first positioning member 17 and to push the profile for positioning and punching. In this case, the profile can be inserted into the support guide rod 14 for a long distance at one time. Similarly, since the support wheel 1C supports the support guide rod 14, the support guide rod 14 can be easily inserted into the profile.

[0081] After the profile is inserted into the support guide rod 14, the holes are punched from the end of the profile close to the operator. The frame block 12 and the guide wheel 1E inside the frame block 12 can well position and fix the profile, and can also facilitate the movement of the profile.

[0082] Then, the second positioning member 162 is disassembled and moved to adjust the position. An adsorption tool, such as an electric vacuum suction cup, can be used to suck the profile, and then the profile is pulled and moved until it contacts the second positioning member 162 and stops. Then, the punching device 18 performs a punching operation on the profile.

[0083] After completing one time of pulling the profile and punching, adjust the position of the second positioning member 162, pull the profile until it contacts the second positioning member 162, and then stop the punching operation, and repeat the above operation until all the punching work is completed.

[0084] This completes the process of punching holes in the profile by the profile punching device of this embodiment.

[0085] The profile punching device of this embodiment arranges a first positioning member on the supporting guide rod, so that when a shorter profile is pushed to punch holes at multiple positions, the profile can be positioned multiple times by moving the position of the first positioning member. By detachably arranging a second positioning member on the positioning profile, the profile can be positioned multiple times by changing the position of the second positioning member on the positioning profile when a longer profile is pulled to punch holes at multiple positions. The punching positioning has high compatibility and low equipment use cost.

[0086] The following is a second embodiment of a profile punching device provided by the present invention that can solve the above technical problems. The main difference between this embodiment and the first embodiment is that the structure of the first positioning member is different. For the first positioning member in the first embodiment, the operator needs to loosen the screw member to slide and adjust the position of the first positioning member after each hole is punched, which has the problems of complex operation and low work efficiency. The structure of this embodiment that is the same as the first embodiment will not be repeated.

[0087] The present embodiment provides a profile punching device for punching holes in axially penetrating profiles, which includes: a mounting frame 11, a frame block 12, a support plate 13, a support guide rod 14, a pad block 15, a positioning profile 16, a first positioning member 17, a second positioning member 162, and a punching device 18.

[0088] A punching work plane 111 is provided at one end of the mounting frame 11, the frame block 12 is fixedly provided on the punching work plane 111, the punching device 18 is provided above the frame block 12, and the frame block 12 is provided with a fixing hole 121 for fixing the profile, and an avoidance hole 122 that penetrates the fixing hole 121 and the external space for the punch 181 to pass through. The avoidance hole 122 through which the punch 181 of the punching device 18 passes is used to perform a punching operation on the profile in the fixing hole 121.

[0089] The support plate 13 is arranged on the top of the mounting frame 11, and one end of the support guide rod 14 is connected to one end of the support plate 13 through a pad block 15. The support guide rod 14 is a set distance away from the support plate 13, and one end of the support guide rod 14 away from the pad block 15 is suspended and extends into the fixing hole 121. The support guide rod 14 is used to be inserted into the interior of the profile, and the support plate 13 can support the bottom surface of the profile.

[0090] The first positioning member 17 is movably connected to the support guide rod 14. When the profile moves toward the pad block 15, the first positioning member 17 contacts the profile for positioning. For shorter profiles, the profile will be positioned with the first positioning member 17 by pushing the profile, and then the punching operation will be performed. At the same time, the profile can be positioned and punched multiple times by moving the position of the first positioning member 17.

[0091] Please refer to Figure 6 and Figure 7 In this embodiment, the first positioning member 17 includes a sliding ring body 27, an extrusion block 21, a mounting plate 22, an unlocking block 23, a limiting rod 28, a guide groove housing 24, a limiting housing 25, an extrusion spring 26, an unlocking spring 29 and a limiting spring 2A.

[0092] The sliding ring body 27 is slidably sleeved on the supporting guide rod 14 , and mounting plates 22 , guide groove housings 24 and limit housings 25 are disposed on opposite sides of the sliding ring body 27 .

[0093] The extrusion block 21 is elastically slidably arranged on the mounting plate 22 through an extrusion spring 26 and passes through the sliding ring body 27. The extrusion spring 26 is used to drive the extrusion block 21 to form an extrusion with the support guide rod 14, so that the sliding ring body 27 and the support guide rod 14 maintain a fixed phase.

[0094] Among them, one side of the extrusion block 21 can be provided with an elastic rubber block for contacting the support guide rod 14, and the elastic rubber block can squeeze the support guide rod 14 more tightly and has a large friction force.

[0095] The unlocking block 23 is elastically slidably arranged in the guide groove housing 24 by means of an unlocking spring 29. The sliding direction of the unlocking block 23 is consistent with the axial direction of the supporting guide rod 14. The unlocking spring 29 is used to drive the unlocking block 23 to slide in the direction close to the frame block 12. One end of the unlocking block 23 extends and protrudes from the end surface of the sliding ring body 27 close to the frame block 12, so as to be used for profile extrusion of the unlocking block 23.

[0096] A bevel groove 211 is provided on one side of the extrusion block 21, and the distance between the end of the bevel groove 211 close to the frame block 12 and the support guide rod 14 is smaller than the distance between the end away from the frame block 12 and the support guide rod 14. A clamping groove 2111 is provided on the side of the end of the bevel groove 211 close to the frame block 12, and an unlocking rod 231 is provided on one side of the unlocking block 23. The unlocking rod 231 is inserted into the bevel groove 211, and the clamping groove 2111 is used to limit the unlocking rod 231 from sliding along the bevel groove 211.

[0097] By squeezing the unlocking block 23 through the profile, the unlocking block 23 can squeeze the inner wall surface of the inclined groove 211 through the unlocking rod 231, so that the extrusion block 21 slides toward the direction close to the support guide rod 14 for extrusion, or slides away from the support guide rod 14 to form unlocking. After unlocking, the sliding ring body 27 can slide along the support guide rod 14 more smoothly.

[0098] The limit rod 28 is elastically slidably disposed in the limit housing 25 by the limit spring 2A. A communication hole is disposed between the limit housing 25 and the guide groove housing 24, and the communication hole is used for the limit rod 28 to extend into the guide groove housing 24. The limit spring 2A is used to drive the limit rod 28 to retract into the limit housing 25.

[0099] Please refer to Figure 8 , Figure 8 The difference in state after the unlocking rod 231 squeezes and drives the squeezing block 21 is shown with a simple schematic diagram and dotted lines. The support guide rod 14 is located at Figure 8 The right side of the middle extrusion block 21.

[0100] The unlocking block 23 includes an initial position, a squeeze position, and an unlocking position on the sliding track. The initial position is located between the squeeze position and the unlocking position, and the squeeze position is located at an end of the initial position away from the frame block 12. Figure 8 In the state where the unlocking block 23 is in the initial position, when the unlocking block 23 is in the squeeze position, the squeezing block 21 will move toward the direction close to the support guide rod 14, and when the unlocking block 23 is in the unlocking position, the squeezing block 21 will move away from the support guide rod 14. However, it should be noted that the movement is relatively subtle. Figure 8The distance dimensions shown do not represent actual dimensions.

[0101] When the unlocking block 23 is located at the initial position, the extrusion block 21 contacts the support guide rod 14 , and the limiting rod 28 extends into the guide groove housing 24 and limits the unlocking block 23 from sliding in the direction close to the frame block 12 .

[0102] It should be noted that the operator needs to first slide and adjust the position of the sliding ring body 27 on the supporting guide rod 14, then control the unlocking block 23 to slide to the initial position, and bend the limiting rod 28 to slide and extend to the guide groove housing 24. Driven by the elastic force of the unlocking spring 29, the unlocking block 23 and the limiting rod 28 are squeezed to form a relatively fixed position relationship. A shallow groove can also be set on the unlocking block 23, and a protrusion matching the groove can be set on the limiting rod 28, so that the limiting rod 28 can better limit the unlocking block 23.

[0103] The profile slides and squeezes the unlocking block 23 in the direction close to the padding block 15, so that the unlocking block 23 can slide to the squeezed position. When the unlocking block 23 is in the squeezed position, the squeezing block 21 contacts the support guide rod 14, and the unlocking block 23 and the limit rod 28 are separated by a set distance. It should be noted that after the unlocking block 23 is squeezed by the profile, a slight distance is formed between the limit rod 28, and this slight distance is based on the limit rod 28 being able to retract into the limit housing 25 under the elastic force of the limit spring 2A.

[0104] The more the unlocking block 23 moves toward the heightening block 15, the more the unlocking rod 231 can pass through the inner wall of the extrusion chute 211, so that the extrusion block 21 extrudes the support guide rod 14 with a greater force, so that the first positioning member 17 maintains a more stable fixed connection with the support guide rod 14. Thus, the first positioning member 17 can better position the profile.

[0105] When the profile slides back in the direction away from the padding block 15, the unlocking block 23 can slide to the unlocking position because the limit rod 28 no longer restricts the sliding of the unlocking block 23. When the unlocking block 23 is in the unlocking position, the extrusion block 21 is at a set distance from the support guide rod 14, and the sliding ring body 27 can slide along the support guide rod 14 more smoothly.

[0106] When the unlocking block 23 is in the unlocking position, the unlocking rod 231 is in the slot 2111, and the slot 2111 blocks the unlocking rod 231 from sliding into the inclined slot 211. In this way, when the profile slides toward the direction close to the padding block 15 again, the profile can push the unlocking block 23 and the sliding ring body 27 to slide along the supporting guide rod 14. Until it reaches the position of the next first positioning member 17, it is positioned again, and the profile is positioned by the next first positioning member 17. When it is positioned again, the profile can be punched for the next time.

[0107] In this embodiment, one end of the unlocking block 23 extending to the end face of the sliding ring body 27 is connected to an extension plate 232, and the extension plate 232 is parallel to the end face of the sliding ring body 27. The extension plate 232 is used to contact the profile so that the profile can stably push the unlocking block 23 to move.

[0108] The working principle of the profile punching device of this embodiment using the first positioning member to position the profile is as follows: first, a plurality of first positioning members 17 are arranged on the support guide rod 14, and the distance between the plurality of first positioning members 17 is adjusted according to the punching spacing of the profile. The unlocking block 23 is controlled to slide to the initial position, the limit rod 28 is moved to slide and extend into the guide groove housing 24 and restrict the unlocking block 23, and the extrusion block 21 is extruded with the support guide rod 14, so that the sliding ring body 27 and the support guide rod 14 maintain a fixed phase.

[0109] Then, the profile is inserted into the support guide rod 14, and the profile is pushed to be squeezed with the expansion plate 232, so that the unlocking block 23 slides, and the unlocking rod 231 can pass through the inner wall surface of the squeezing chute 211, so that the squeezing block 21 squeezes the support guide rod 14 with a greater force, and further the first positioning member 17 and the support guide rod 14 are more stably fixedly connected. At this time, the first positioning member 17 completes the positioning of the profile, and then the punching device 18 performs a punching operation on the profile.

[0110] After completing a punching operation, the profile is pulled back to slide. Since the limit rod 28 no longer restricts the sliding of the unlocking block 23, the unlocking block 23 can slide to the unlocking position. At this time, the extrusion block 21 is at a set distance from the support guide rod 14, and the sliding ring body 27 can slide along the support guide rod 14 more smoothly. Then the profile is pushed to slide in the direction close to the pad block 15, and the profile can push the unlocking block 23 and the sliding ring body 27 to slide along the support guide rod 14 together. Until it reaches the position of the next first positioning member 17, it is re-positioned, and the profile is positioned by the next first positioning member 17. When it is re-positioned, the profile can be punched for the next time.

[0111] The above steps can be repeated to perform multiple punching operations on the profile. After punching a hole each time, there is no need for the operator to go to the side of the support guide rod 14 to adjust the position of the first positioning member 17. The positioning and punching operation is simple and convenient with high work efficiency.

[0112] In summary, although the present invention has been disclosed as above by embodiments, the above embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
