Description

Technical Field

[0001] This utility model relates to a punch press, or more precisely, a gantry punch press with a synchronization structure. Background Technology

[0002] like Figure 8 As shown, the existing gantry punch press includes an upper crossbeam 110, a lower crossbeam 120, and a sliding beam 210. A pair of hydraulic cylinders 1130 are mounted on the upper crossbeam 110 to drive the sliding beam 210. Since the upper crossbeam 110 and lower crossbeam 120 rely entirely on the guide column 130 for force distribution, the guide column 130 is prone to deformation. Furthermore, because the movements of the two hydraulic cylinders 1130 are difficult to synchronize perfectly, the left and right sides of the sliding beam 210 are difficult to move synchronously, severely affecting machining accuracy, especially for long, narrow parts such as profiles. Utility Model Content

[0003] Therefore, it is necessary to provide a gantry punch press with a synchronization structure to address the aforementioned technical problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] In a preferred embodiment of this utility model, the main shaft is provided with gear mounting seats at both ends, and the synchronous gear is fixed on the gear mounting seats.

[0010] In a preferred embodiment of this utility model, the synchronization frame and the synchronization rack are connected by welding, screws, or are an integral structure.

[0011] In a preferred embodiment of this utility model, the upper crossbeam comprises a long strip-shaped upper beam body, with an upper base and a drive cylinder at both ends of the upper beam body.

[0012] The lower crossbeam comprises a long, strip-shaped lower beam body, with lower bases at both ends of the lower beam body. The guide post is located between the upper base and the lower base.

[0013] The sliding part includes a long strip-shaped sliding beam, on which a pair of drive connecting seats are provided. The output shaft of the drive cylinder is connected to and drives the drive connecting seats. Sliding bases are provided at both ends of the sliding beam, and several guide bearings are provided on the sliding bases. The guide post passes through the corresponding guide bearing.

[0014] In a preferred embodiment of this utility model, the number of guide bearings is eight.

[0015] In a preferred embodiment of this utility model, a reinforcing plate is provided between the upper base and the lower base.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figures 1 to 3 As shown, the gantry punch press with a synchronization structure includes a fixed part 10 and a sliding part 20, the sliding part 20 being slidably disposed on the fixed part 10.

[0033] The fixing part 10 includes a horizontally arranged upper crossbeam 11 and a horizontally arranged lower crossbeam 12. A plurality of guide posts 13 are provided between the upper crossbeam 11 and the lower crossbeam 12. A pair of upper synchronization components 15 are provided on the upper crossbeam 11, and a pair of lower synchronization components 24 are provided on the sliding part 20. The lower synchronization components 24 cooperate with the upper synchronization components 15.

[0034] like Figure 4 As shown, the upper crossbeam 11 includes an elongated upper beam body 111, with an upper base 112 and a drive cylinder 113 at both ends of the upper beam body 111. The lower crossbeam 12 includes an elongated lower beam body 121, with a lower base 122 at both ends of the lower beam body 121, and the guide post 13 is located between the upper base 112 and the lower base 122.

[0035] In addition, the drive cylinder 113 is a hydraulic cylinder.

[0036] The sliding part 20 includes a long strip-shaped sliding beam 21. A pair of drive connecting seats 23 are provided on the sliding beam 21. The output shaft of the drive cylinder 113 is connected to and drives the drive connecting seats 23. Sliding bases 22 are provided at both ends of the sliding beam 21. Several guide bearings 25 are provided on the sliding bases 22. The guide post 13 passes through the corresponding guide bearings 25.

[0037] It should be noted that there are eight of these guide bearings 25.

[0038] In addition, a reinforcing plate 14 is provided between the upper base 112 and the lower base 122. The reinforcing plate 14 is connected to the upper base 112 and the lower base 122 by welding or by screws.

[0039] The reinforcing plate 14 includes a first plate body 141, and second plates 142 are provided on both sides of the first plate body 141. The arrangement direction of the second plates 142 is perpendicular to the first plate body 141.

[0040] like Figure 5 As shown, the upper synchronization component 15 includes a main shaft 151, with synchronization gears 152 at both ends of the main shaft 151. The upper synchronization component 15 includes a square-shaped synchronization frame 241, with synchronization racks 242 on both side walls of the synchronization frame 241. The synchronization racks 242 cooperate with the synchronization gears 152.

[0041] In addition, the main shaft 151 is provided with a bearing seat 153, which is fixed to the upper crossbeam 11. The two ends of the main shaft 151 are provided with gear mounting seats 154, and the synchronous gear 152 is fixed on the gear mounting seats 154.

[0042] It should be noted that the synchronization frame 241 and the synchronization rack 242 are connected by welding, screws, or are an integral structure.

[0043] The working principle of this gantry punch press with synchronous structure will be explained below.

[0044] like Figure 1 and Figure 2 As shown, when stamping is required, a pair of drive cylinders 113 start simultaneously. The output end of the drive cylinders 113 drives the drive connecting seat 23 on the sliding part 20, causing the entire sliding part 20 to descend. During the descent, the synchronous rack 242 of the upper synchronous assembly 15 located on the left side of the sliding beam 21 meshes with the corresponding synchronous gear 152 on the left side of the upper synchronous assembly 15, causing the pair of upper synchronous assemblies 15 to rotate synchronously in opposite directions. At the same time, the synchronous rack 242 on the right side meshes with the synchronous gear 152 on the right side, also rotating relative to each other at the same speed. By utilizing the clamping effect of the rack-gear meshing structure on the left and right sides, the synchronous rise and fall of the left and right sides of the entire sliding part 20 can be ensured, greatly improving the machining accuracy of the gantry press, especially for machining longer profiles.

[0045] Furthermore, because the punch press employs a reinforcing plate 14, the sides of the punch press form a single, integral structure, such as... Figure 1 As shown in the dashed box S, this integral structure effectively enhances the overall strength of the punch press, prevents deformation of the guide post, and improves the stability of the punch press.

[0046] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
