Description

Technical Field

[0001] The utility model relates to the field of profile processing, in particular to a profile clamping component and a profile sawing machine tool. Background Art

[0002] The processing and manufacturing of profiles involves a variety of processing procedures such as extrusion molding, heat treatment, surface treatment, sawing, drilling, end milling, etc. The sawing process is to accurately cut the profile according to the established size data, and the most common processing is at a cutting angle of 45° and 90°.

[0003] In the prior art, in order to be able to clamp the profile stably and reliably, the profile clamping assembly in the sawing bed includes an upper clamping unit and a front clamping unit, the upper clamping unit includes an upper pressure plate and an upper cylinder, the upper pressure plate realizes the positioning and clamping of the profile in the vertical direction under the drive of the cylinder extension and retraction, the front clamping unit includes a front cylinder and a front pressure plate, the front pressure plate moves in the horizontal plane driven by the front cylinder to realize the positioning and clamping of the profile in the front and rear directions, and in order to ensure that the saw blade can cut at a 45° angle, the front cylinder is tilted to ensure the tilted extension direction, so that the moving route of the front pressure plate avoids the working range of the saw blade.

[0004] With the increasing content of profile processing and the increase in the types of sawing machines, on some sawing machines where the sawing components do not have the X-axis movement function, the corresponding manipulator is required to pull the profile along the X-axis of the bed to saw the corresponding position. For example, some window frame profiles need to cut off the end corners after sawing in order to install the corner protection structure. The two parts of the profile that need to be cut off are successively driven by the manipulator to move along the X-axis to avoid cutting the corners. At this time, the upper clamping unit needs to release the clamping. Since the corresponding cylinder cannot stop at any set position, the cylinder is fully retracted each time the clamping is released. However, for the movement of the profile, it is only necessary to lift the corresponding pressure plate a short distance and no longer contact the profile. It can be seen that the cylinder has a useless stroke, which undoubtedly increases the time for releasing and resuming the clamping, greatly affecting the production efficiency.

DETAILED DESCRIPTION

[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent. Specific implementation method 1

[0028] like Figure 1As shown, this specific embodiment provides a profile clamping assembly, including an upper clamping unit and a front clamping unit, the upper clamping unit includes an upper pressure plate 6, and the upper clamping unit also includes a first upper pressure cylinder 1, the first upper pressure cylinder 1 is vertically arranged, the piston rod of the first upper pressure cylinder 1 is connected to the second upper pressure cylinder 3, the second upper pressure cylinder 3 is connected to the upper pressure plate 6 through a connecting plate 5, and the connecting plate 5 can be movably arranged on the bed, the stroke of the first upper pressure cylinder 1 is greater than the stroke of the second upper pressure cylinder 3, in this specific embodiment, a fixed plate 2 is arranged on the cylinder body of the first upper pressure cylinder 1, the fixed plate 2 is used to connect with the machine tool, the first upper pressure cylinder 1 is arranged downward, and a guide rail is arranged on the connecting plate 5, and the guide rail is used to be movably connected to the guide block on the machine tool.

[0029] Through the cooperation of the first upper pressure cylinder 1 and the second upper pressure cylinder 3, this specific embodiment can, when the profile needs to be moved, lift the upper pressure plate 6 through the action of the second upper pressure cylinder 3 with a smaller stroke, thereby avoiding the situation where the cylinder piston rod is fully moved into place in the case of one cylinder, eliminating invalid stroke, saving the distance for loosening and resuming clamping, shortening the working time of the profile clamp, and greatly improving production efficiency.

[0030] like Figure 1 As shown, in the present specific embodiment, the first upper pressure cylinder 1 is arranged downward, and in order to facilitate the connection between the two cylinders, the second upper pressure cylinder 3 is arranged vertically upward, that is, the second upper pressure cylinder 3 is located at the lower part of the first upper pressure cylinder 1, and the piston rod of the second upper pressure cylinder 3 is connected with the piston rod of the first upper pressure cylinder 1, and the cylinder body of the second upper pressure cylinder 3 is connected with the connecting plate 5 through the support 4. The first upper pressure cylinder 1 adopts a clamping cylinder to ensure that it can stably and reliably stop at the corresponding position. In the present specific embodiment, the stroke of the first upper pressure cylinder 1 is 150mm, and the stroke of the second upper pressure cylinder 3 is 10mm.

[0031] The working process of this upper pressure clamping unit is:

[0032] When the clamping cylinder is needed, the first upper pressure cylinder 1 and the second upper pressure cylinder 3 are extended at the same time, driving the upper pressure plate 6 to move downward through the connecting plate 5 until they are in place; when the profile needs to be moved, the second upper pressure cylinder 3 retracts, and its cylinder body moves upward, thereby driving the connecting plate 5 and the upper pressure plate 6 to move upward until they are in place.

[0033] It is understandable that the first upper pressure cylinder 1 and the second upper pressure cylinder 3 can also be both arranged upward and the first upper pressure cylinder 1 is located at the lower part of the second upper pressure cylinder 3. At the same time, the piston rod of the first upper pressure cylinder 1 is connected to the cylinder body or piston rod of the second upper pressure cylinder. This is easy for technicians in this field to think of after seeing this specific implementation method, and it will not be repeated in this article. Compared with the arrangement of the first upper pressure cylinder 1 and the second upper pressure cylinder 3 adopted in this specific implementation method, the fixed plate only bears the force of the first upper pressure cylinder 1, has a smaller load-bearing capacity, and has better stability.

[0034] like Figure 2 As shown, in this specific embodiment, the front clamping unit includes a lower laminate 9. In order to avoid the processing space of the saw blade, the lower laminate 9 is tilted, and the tilt angle of the lower laminate 9 is determined by the minimum sawing angle of the saw blade. The lower laminate 9 is connected to a first drive component; due to the different heights of the profiles, in order to meet the requirements of having a relatively stable clamping ability for profiles of various heights, an upper laminate 14 is movably arranged on the lower laminate 9, and the upper laminate 14 is connected to a second drive component, and the upper laminate 14 and the lower laminate 9 are arranged in parallel; when clamping a shorter profile, only the lower laminate 9 needs to be extended, and when the profile height is higher, the upper laminate 14 and the lower laminate 9 need to be extended together; in order to reduce the friction of the profile movement, the clamping surfaces of the upper laminate 14 and the lower laminate 9 are provided with ball bearings. After such a setting, the front clamping unit can move the profile without releasing the clamping, which further saves time and improves production efficiency.

[0035] like Figure 2 As shown, since the lower laminate plate 9 needs to be set at an angle, in order to reduce the space occupied by the profile clamp in the inclined direction and avoid bumps and interference, in the present specific embodiment, the first driving assembly includes a first forward pressure cylinder 7 and a support plate 8. The support plate 8 is set along the Y direction. The support plate 8 can be connected to the bed. The cylinder body of the first forward pressure cylinder 7 is hinged to the support plate 8, and the piston rod of the first forward pressure cylinder 7 is hinged to the lower laminate plate 9.

[0036] In this specific embodiment, the second driving assembly includes a second forward-pressure cylinder 10 . Specific implementation method 2

[0038] like Figure 3 and Figure 4 As shown, this specific embodiment provides a profile sawing machine, including a support base 20, on which a workbench 15 and a workbench 2 13 are arranged, a limit plate 12 is arranged at the rear of the workbench 15, and both the workbench 15 and the workbench 2 13 include a work table surface and a lower support portion 11, and also include a profile clamping assembly of specific embodiment one, the fixing plate 2 of the first upper pressure cylinder 1 is arranged at the rear of the workbench 15, the connecting plate 5 guide rail is movably arranged on a slider at the rear of the support portion 11 of the workbench 15, the support plate 8 is connected to the front of the support portion 11 of the workbench 15, and the lower laminating plate 9 is movably arranged on the upper surface of the workbench.

[0039] In order to facilitate sawing and blanking and minimize space occupancy, in the present specific embodiment, the support parts 11 of workbench 15 and workbench 2 13 can be movably arranged on the support seat 20, and the lower parts of the support parts 11 of workbench 15 and workbench 2 13 are provided with blanking cylinders 17 and guide rails, and the piston rods of the blanking cylinders 17 are connected to the fixed seats 19 on the support seat 20, a blanking port is arranged between workbench 15 and workbench 2 13, and a collection box 21 is arranged at a position on the support seat 20 corresponding to the blanking port.

[0040] like Figure 4 As shown, the sawing machine tool of this specific embodiment is used in conjunction with a discharge robot 23. Since the discharge robot 23 is provided with a corresponding clamping assembly, in this specific embodiment, the corresponding clamping assembly is no longer provided on the work table 2. Moreover, in order to reduce costs, in this specific embodiment, the sawing assembly 22 is not provided with an X-direction driving assembly, that is, the sawing assembly 22 does not have the function of moving along the X-direction, and the movement of the profile can be driven by the discharge robot 23 to achieve movement.

[0041] like Figure 3 As shown, in the prior art, a discharging robot 23 is generally used to discharge the finished product after sawing, but some types of profiles need to further saw the sharp corners at the tip, so they need to be returned after sawing, that is, the discharging robot 23 moves a set distance in the opposite direction of the discharging, and moves the cut profile to the corresponding position, but due to the slippage between the profile and the work table 2, the stopping position of the profile is inaccurate. In order to improve the accuracy of the returned material, in this specific embodiment, a feeding cylinder 18 is also provided at the lower part of the work table 2 13, and the piston rod of the feeding cylinder 18 is connected to the fixed seat 19; by moving the feeding cylinder 18 and the discharging robot 23 in the same direction, the speed difference between the work table 2 13 and the profile is reduced, the slippage distance is shortened, the return accuracy of the profile is improved, and the accuracy of the cutting angle position is ensured.

[0042] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0043] 1. Through the cooperation of the first upper pressure cylinder 1 and the second upper pressure cylinder 3, when the profile needs to be moved, the upper pressure plate 6 can be lifted by the action of the upper pressure cylinder with a smaller stroke, avoiding the situation where the cylinder piston rod is fully moved into place in the case of one cylinder, eliminating invalid strokes, saving the distance for loosening and restoring clamping, shortening the working time of the profile clamp, and greatly improving production efficiency;

[0044] 2. By setting up a double-layer laminate structure, profiles of various heights can be stably clamped, thereby expanding the scope of application of the clamping assembly; by setting the support plate 8 along the Y direction, the space occupied by the clamping assembly in the inclined direction can be reduced;

[0045] 3. The setting of the ball bearing can reduce the friction generated by the X-direction movement of the profile. The front clamping unit can move the profile without releasing the clamping, which further saves time and improves production efficiency.

[0046] 4. Material dropping is achieved by moving the workbench 15 and the workbench 2 13, making the machine tool compact and occupying little space;

[0047] 5. By setting the feeding cylinder 18, the workbench 2 13 can move in the same direction when the discharging robot 23 returns the profile, reducing the speed difference between the profile and the discharging robot 23, reducing the slipping tendency, and ensuring that the discharging robot 23 returns the length more accurately.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
