Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a clamping mechanism of a punching device for aluminum special-shaped profiles. Background Technique

[0002] Aluminum special-shaped profiles are components or profiles with special shapes made of aluminum alloy materials, which can be processed and manufactured through processes such as extrusion, drawing, and rolling;

[0003] There are many types of aluminum special-shaped profiles. According to their different shapes and uses, they can be divided into various types, such as square tubes (with a square or rectangular shape, commonly used in construction, decoration, machinery and other fields), angle materials (with an L-shaped shape, commonly used in construction, frames, electronic equipment, etc.), round tubes (with a circular shape), etc.;

[0004] Due to the special nature of aluminum special-shaped profiles, there are many types, and the quantity of profiles in each production batch is small. When clamping and positioning and punching through the current clamping mechanism, there are the following defects:

[0005] The current clamping mechanism has a relatively simple positioning and cannot effectively clamp according to the special nature of aluminum special-shaped profiles, including the size and shape of aluminum special-shaped profiles, to assist punching; secondly, the clamping structure is not stable enough and the applicability is not high. Therefore, we propose a clamping mechanism of a punching device for aluminum special-shaped profiles. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art. The current clamping mechanism has a relatively simple positioning and cannot effectively clamp according to the special nature of aluminum special-shaped profiles, including the size and shape of aluminum special-shaped profiles, to assist punching; secondly, the clamping structure is not stable enough and the applicability is not high.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A clamping mechanism of a punching device for aluminum special-shaped profiles includes a punching platform and a punching area. The punching area is centrally arranged at the top center of the punching platform, and the axis of the punching area along the length direction on the upper end surface of the punching platform is used for placing aluminum special-shaped profiles. On the upper end surface of the punching platform along the length direction, a limiting mechanism and a positioning mechanism are respectively arranged on the front and rear sides of the punching area. There are multiple groups of the positioning mechanism corresponding to the limiting mechanism. Lifting grooves are opened on the left and right sides of the upper end surface of the punching area along the length direction of the punching platform, and lifting frames are installed in the lifting grooves;

[0009] The limiting mechanism includes a limiting plate and a cylinder a. The cylinder a is installed at the top of the punching platform and the output end faces the punching area. The limiting plate is installed at the output end of the cylinder a, and the limiting plate is arranged along the length direction of the punching platform and cooperates with multiple groups of limiting mechanisms;

[0010] The positioning mechanism includes a positioning plate, cylinder b, adjustment slot, cylinder c, and a lifting clamping plate. Cylinder b is installed at the top of the punching platform with its output end facing the punching area. The positioning plate is installed at the output end of cylinder b. The adjustment slot is vertically opened through both side surfaces of the positioning plate. Cylinder c is vertically installed on the side of the positioning plate away from the punching area, with its output end facing the bottom and the lifting clamping plate installed thereon.

[0011] Furthermore, both the limiting plate and cylinder a are installed inside housing a at the top of the punching platform, and there are several groups of cylinder a.

[0012] Furthermore, the positioning plate, cylinder b, adjustment slot, cylinder c, and the lifting clamping plate are all installed inside housing b at the top of the punching platform.

[0013] Furthermore, a positioning pad is embedded and bonded to the lower half of the side of the positioning plate facing the punching area, and a clamping pad is bonded to the bottom of the lifting clamping plate.

[0014] Furthermore, the upper end surface of the lifting frame is "arc-shaped" and is driven by cylinder d installed inside the lifting slot. Through the operation of cylinder d, it is used to lift the aluminum profile for displacement or picking up of the aluminum profile.

[0015] Furthermore, the top view of the lifting clamping plate is in the shape of "H" and slides vertically in the adjustment slot. Through the operation of cylinder c, it drives the lifting clamping plate to adjust up and down in the adjustment slot.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] Through the setting of the limiting mechanism and multiple groups of positioning mechanisms, the present utility model can effectively clamp and position aluminum profiles of different sizes and shapes. The limiting mechanism uses cylinder a to drive the limiting plate to achieve the limitation of the aluminum profile in one side direction and provide a contact surface (i.e., for the side surface of the aluminum profile to contact). The positioning mechanism drives the positioning plate through cylinder b and combines with the lifting clamping plate driven by cylinder c to perform precise adjustment and clamping in the height and width directions, which can adapt to aluminum profiles of various shapes and sizes, greatly improving the applicability and stability of the clamping mechanism and ensuring the stability of the aluminum profile during the punching process.

[0034] Embodiment

[0035] As Figures 1-4 shown, this utility model provides a technical solution: a clamping mechanism of an aluminum profile punching device, including a punching platform 1 and a punching area 2. The punching area 2 is centrally arranged at the top center of the punching platform 1, and the central axis of the upper end surface of the punching platform 1 along the length direction in the punching area 2 is for placing aluminum profiles. On the upper end surface of the punching platform 1 along the length direction, a limiting mechanism 3 and a positioning mechanism 4 are respectively arranged on the front and rear sides of the punching area 2. The positioning mechanism 4 has multiple groups corresponding to the limiting mechanism 3. Lifting grooves 5 are opened on the left and right sides of the upper end surface of the punching platform 1 along the length direction of the punching area 2, and a lifting frame 6 is installed in the lifting grooves 5;

[0036] Among them, the number of the positioning mechanisms 4 is designed according to requirements, and the lifting frame 6 is built in the lifting groove 5.

[0037] As Figure 3 shown, the limiting mechanism 3 includes a limiting plate 31 and a cylinder a32. The cylinder a32 is installed at the top of the punching platform 1 and the output end faces the punching area 2. The limiting plate 31 is installed at the output end of the cylinder a32, and the limiting plate 31 is arranged along the length direction of the punching platform 1 to cooperate with multiple groups of limiting mechanisms 3;

[0038] Among them, both the limiting plate 31 and the cylinder a32 are installed in a housing a33 at the top of the punching platform 1, and there are several groups of cylinders a32, which are protected by the housing a33 to avoid being affected by debris and dust.

[0039] As Figure 2 and 4 shown, the positioning mechanism 4 includes a positioning plate 41, a cylinder b42, an adjustment groove 43, a cylinder c44 and a lifting clamping plate 45. The cylinder b42 is installed at the top of the punching platform 1 and the output end faces the punching area 2. The positioning plate 41 is installed at the output end of the cylinder b42. The adjustment groove 43 is vertically opened through both side faces of the positioning plate 41. The cylinder c44 is vertically installed on the side of the positioning plate 41 away from the punching area 2, and the output end faces the bottom and installs the lifting clamping plate 45.

[0040] Among them, the positioning plate 41, cylinder b 42, adjustment slot 43, cylinder c 44, and lifting clamping plate 45 are all installed in the housing b 46 at the top of the punching platform 1. They are protected by the housing b 46 to prevent debris and dust from affecting them.

[0041] It should be added that a positioning pad 47 is embedded and bonded to the lower half of the positioning plate 41 facing the punching area 2 side, and a clamping pad 48 is bonded to the bottom of the lifting clamping plate 45.

[0042] The top view of the lifting clamping plate 45 is in an "H" shape and slides vertically in the adjustment slot 43. Through the operation of the cylinder c 44, the lifting clamping plate 45 is driven to adjust up and down in the adjustment slot 43. If the aluminum profile needs to be displaced or picked up, the cylinder d 61 starts to work, driving the lifting frame 6 to move up and down in the lifting slot 5. Since the upper end surface of the lifting frame 6 is "arc-shaped", this design can better match the shape of the aluminum profile and avoid damage during the lifting process.

[0043] It should be noted that after the lifting clamping plate 45 lifts the aluminum profile, picking up the part is more convenient. For longer, heavier, or more tightly packed aluminum profiles, after lifting, the displacement adjustment also greatly reduces friction.

[0044] Such as Figure 2 and Figure 5 As shown, the upper end surface of the lifting frame 6 is "arc-shaped" and is driven by the cylinder d 61 installed in the lifting slot 5 at the bottom. Through the operation of the cylinder d 61, it is used to lift the aluminum profile for displacement or picking up of the aluminum profile.

[0045] The working process of the present utility model: The aluminum profile is placed along the central axis in the length direction of the punching area 2. After the punching position corresponds to the punching area 2, the cylinder a 32 starts to work, driving the limiting plate 31 to move along the length direction of the punching platform 1 until the limiting plate 31 contacts one side of the aluminum profile. Then the cylinder b 42 starts to work, driving the positioning plate 41 to move towards the punching area 2 until the positioning pad 47 on the positioning plate 41 contacts the other side of the aluminum profile. Then the cylinder c 44 starts to work, driving the lifting clamping plate 45 to adjust up and down in the adjustment slot 43 until the clamping pad 48 at the bottom of the lifting clamping plate 45 contacts the upper surface of the aluminum profile, and then cooperates with the limiting plate 31, the punching platform 1, and the two supporting base surfaces and the positioning plate 41 to clamp the aluminum profile. After the aluminum profile is stably clamped, the punching device above the punching area 2 can start punching operations. Since the aluminum profile has been accurately positioned and clamped, the punching process will be more stable and accurate.

[0046] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
