Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, specifically to a continuous punching mechanism for aluminum profile processing. Background Technology

[0002] As an important structural material, aluminum profiles often need to be punched before they can be assembled and used for connection. Aluminum profile punching mechanism is a device that can open holes on the surface of aluminum profiles. At present, in order to ensure the accuracy of the punching position, cylinder-driven pressure block or screw pair structure is generally used as positioning fixture.

[0003] In the current technology, when punching aluminum profiles, the fixing structure is generally a cylinder, screw, etc. Although such structures can achieve effective positioning, when performing continuous multi-hole processing, the aluminum profile often needs to be unlocked and locked again after it moves. When drilling continuously, the operation is cumbersome, the continuity is poor, and it is difficult to achieve efficient continuous operation. Utility Model Content

[0004] The purpose of this invention is to provide a continuous punching mechanism for aluminum profile processing, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous punching mechanism for aluminum profile processing, comprising a support box and a punching module mounted thereon;

[0006] A limiting component is disposed at the top of the support box;

[0007] A hole positioning assembly is disposed on the outer wall of the support box;

[0008] A barrier component is disposed on the hole positioning component;

[0009] The hole positioning assembly includes a bracket, a sliding plate, a positioning rod, and a receiving sleeve. The bracket is fixedly connected to the outer wall of the support box. The sliding plate can drive the receiving sleeve to adjust along the movement direction of the aluminum material. The positioning rod is slidably connected to the inner wall of the receiving sleeve. The bottom of the positioning rod and the side facing the support box are set as a slope.

[0010] Preferably, a screw and a limiting rod are fixedly connected to the side of the bracket away from the support box, and the sliding plate is threadedly connected to the screw and slidably connected to the limiting rod.

[0011] Preferably, the outer wall of the receiving sleeve is fixedly connected to the sliding plate, the bottom of the positioning rod is rotatably connected to a roller, and the receiving sleeve and the positioning rod are elastically connected by a return spring.

[0012] Preferably, the highest point of the bottom slope of the positioning rod is at the same height as the uppermost outer wall of the aluminum profile.

[0013] Preferably, the limiting component includes a limiting plate fixed to the top of the support box, the limiting plate is configured in two sets, the two sets of limiting plates are arranged opposite to each other, and the limiting plate is L-shaped.

[0014] Preferably, a guide plate is fixedly connected to the side of the limiting plate away from the bracket, the guide plate is set in an inclined shape, and side wheels are rotatably connected to the inner walls of the two sets of limiting plates on opposite sides.

[0015] Preferably, the blocking component includes a fixed plate fixedly connected to the outer wall of the sliding plate. Support shafts are rotatably connected to both sides of the bottom surface of the fixed plate. A swing rod is fixedly connected to the bottom end of the support shaft. Rotating sleeves are rotatably connected to the bottom surfaces of the two sets of swing rods on opposite sides. The support shafts and swing rods correspond one-to-one. The swing rods and the fixed plate are elastically connected by torsion springs.

[0016] Compared with the prior art, the beneficial effects provided by this utility model are as follows:

[0017] 1. By using limiting components and hole positioning components, when punching aluminum profiles, the aluminum profiles are first guided and their position is restricted by the limiting components to prevent them from moving back and forth. Then, after the punching module punches holes on the surface of the aluminum profiles, it continues to push backward. The slope of the positioning rod is squeezed upward by the outer wall of the aluminum profile and then inserted into the opening of the aluminum profile. Pulling the aluminum profile backward makes the side of the positioning rod without the slope tightly attached to the side wall of the opening of the aluminum profile. Thus, when the aluminum profile is punched, there is no need to frequently fix and unlock it. Just push and pull to ensure that the spacing between every two openings is the same. The operation is simple and has strong continuity.

[0018] 2. By using the limiting component, when making the first hole in the aluminum profile, one side of the aluminum profile is tightly pressed against the rotating sleeve. At this time, as the aluminum profile is pushed forward, the operator will feel obvious resistance. When the operator's rear view is poor, the torsion spring can provide an early warning to the operator to ensure that the opening position of the first hole is the same as the distance between the subsequent holes. At the same time, when the operator is making the second hole, the rotating sleeve will press against both sides of the aluminum profile. The component force formed by the reset of the rotating sleeve can drive the aluminum profile to be constantly subjected to a component force moving towards the positioning rod without slope, thereby reducing the force required by the operator to pull the aluminum profile and ensuring accurate hole making.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-6 The present invention provides a technical solution: a continuous punching mechanism for aluminum profile processing, comprising a support box 1 and a punching module 2 mounted thereon;

[0029] Limiting component 3 is located on the top of support box 1; it is used to guide the aluminum profile to be centered while restricting the aluminum profile from moving back and forth.

[0030] Hole positioning component 4 is installed on the outer wall of support box 1; it is used to position the entire aluminum profile through the hole after the hole is opened, so as to ensure that the distance between the two holes is always equal.

[0031] The blocking component 5 is set on the hole positioning component 4; when the hole positioning component 4 fails to function when the first hole is opened, the rotating sleeve 55 can provide a warning and the torsion spring 53 can push back the aluminum profile to ensure that the first hole can also be put into production. At the same time, the torsion spring 53 always drives the rotating sleeve 55 to reset, making the effect of pulling the aluminum profile to fit the side of the positioning rod 46 without the slope more secure and reducing the risk of loosening.

[0032] The hole positioning assembly 4 includes a bracket 41 for supporting the hole positioning assembly 4 and the limiting assembly 3, a sliding plate 42 for enabling the hole positioning assembly 4 to adapt to openings with different spacings, a positioning rod 46 for inserting into the opening of the aluminum profile to fix the position of the aluminum profile, and a receiving sleeve 45 for accommodating the positioning rod 46 and restricting its movement. The bracket 41 is fixedly connected to the outer wall of the support box 1. The sliding plate 42 can drive the receiving sleeve 45 to adjust along the movement direction of the aluminum material. The positioning rod 46 is slidably connected to the inner wall of the receiving sleeve 45. The bottom of the positioning rod 46 and the side facing the support box 1 are set as a slope so that when the bottom of the positioning rod 46 contacts the outer wall of the aluminum profile, a component force can be generated through the slope to push the positioning rod 46 upward.

[0033] In embodiment 2, a screw 43 for driving the sliding plate 42 to move and a limiting rod 44 for limiting the displacement of the sliding plate 42 and preventing its deflection are fixedly connected to the side of the bracket 41 away from the support box 1. The sliding plate 42 is threadedly connected to the screw 43 and slidably connected to the limiting rod 44. The outer wall of the receiving sleeve 45 is fixedly connected to the sliding plate 42. The bottom of the positioning rod 46 is rotatably connected to a roller 47 for reducing friction and preventing scratches on the surface of the aluminum profile when the positioning rod 46 is between the two holes. The receiving sleeve 45 and the positioning rod 46 are elastically connected by a reset spring 48 for driving the positioning rod 46 to reset. The highest point of the bottom slope of the positioning rod 46 is at the same height as the uppermost outer wall of the aluminum profile, so that when the aluminum profile is pushed twice through the opening, the positioning rod 46 can be stably lifted by the slope of the positioning rod 46, while ensuring that the device operation is simpler.

[0034] Example 3: The limiting component 3 includes a limiting plate 31 fixed to the top of the support box 1. The limiting plate 31 is configured as two sets, which are arranged opposite each other. The two sets of limiting plates 31 work together to ensure the state of the aluminum profile and prevent it from deflecting. The limiting plate 31 is L-shaped. A guide plate 32 for guiding the aluminum profile into the limiting area of ​​the limiting plate 31 is fixedly connected to the side of the limiting plate 31 away from the bracket 41. The guide plate 32 is inclined. Side wheels 33 for reducing the friction of the aluminum profile in the limiting plate 31 are rotatably connected to the inner wall of the opposite side of the two sets of limiting plates 31.

[0035] Example 4: The blocking component 5 includes a fixed plate 51 fixedly connected to the outer wall of the sliding plate 42. Both sides of the bottom surface of the fixed plate 51 are rotatably connected to a support shaft 52 for supporting the rotation of the swing arm 54. The bottom end of the support shaft 52 is fixedly connected to a swing arm 54 for allowing the rotating sleeve 55 to rotate around the support shaft 52. The bottom surfaces of the two sets of swing arms 54 are respectively rotatably connected to a rotating sleeve 55 for blocking the position of the aluminum profile and reducing the friction when the aluminum profile moves. The support shaft 52 and the swing arm 54 correspond one-to-one. The swing arm 54 and the fixed plate 51 are elastically connected by a torsion spring 53 for driving the swing arm 54 to reset.

[0036] Working principle: One end of the aluminum profile is inserted along the inclined guide plate 32, allowing it to enter the guide channel formed by two sets of L-shaped limiting plates 31. The limiting plates 31 ensure that the aluminum profile is centered and does not shift in the front-to-back direction. The side wheels 33 effectively reduce the moving friction and push the aluminum profile so that its end is in close contact with the two rotating sleeves 55 of the blocking component 5. At this time, the operator needs to overcome the reset torque of the torsion spring 53 acting on the swing rod 54 in order to continue pushing. The tactile resistance provided in this process is the positioning warning, which determines the starting position of the first hole. Subsequently, the punching module 2 punches the aluminum profile to punch out the first hole.

[0037] After punching the first hole, the aluminum profile continues to advance. At this point, the slope at the bottom of the positioning rod 46 of the hole positioning assembly 4 contacts the upper surface of the aluminum profile. Under the action of the slope component force, the positioning rod 46 overcomes the elastic force of the return spring 48 and lifts upward. The receiving sleeve 45 retracts inward, and the bottom roller 47 rolls on the surface of the profile to prevent scratches. When the positioning rod 46 moves directly above the first hole, its lower end quickly falls into the hole under the push of the return spring 48. After the positioning rod 46 falls into the hole, it pulls the aluminum profile back. At this time, the vertical side wall of the positioning rod 46 without slope is tightly fitted with the inner wall of the hole. This precisely limits the position of the aluminum profile, ensuring that the distance between the next punching position and the already punched position is fixed. During this pull-back process, the rotating sleeve 55 of the blocking component 5 is pressed against the side of the aluminum profile under the pressure of the torsion spring 53. The friction force generated can be decomposed into a component force pointing in the direction of the positioning rod 46. This component force helps the aluminum profile to fit more stably against the outer wall of the positioning rod 46 on the side without the slope at the opening. Moreover, the rotating sleeve 55 is rotatably connected to the swing rod 54, so no large friction will be generated during subsequent pushing. After the second punching is completed, the above push and pull action is repeated to achieve continuous and equidistant processing of subsequent holes.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
