[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0026] Reference Figure 1-4As shown, this embodiment provides a gantry press, including a frame 1. A pressure head assembly 2 is provided at the top of the frame 1, and a material translation assembly is provided at the bottom of the frame 1 opposite to the pressure head assembly 2. The material translation assembly includes a support plate 31, a translational force device 32, and a sliding table 33. The support plate 31 is detachably connected to the top surface of the bottom crossbeam 102 of the frame 1. There are at least two support plates 31, and the length direction of the support plates 31 is parallel to the direction of material translation. The translational force device 32 is fixedly connected to the bottom crossbeam 102. The highest point of the translational force device 32 is lower than the highest point of the support plate 31 to avoid mechanical damage such as squeezing by the sliding table 33. The bottom surface of the sliding table 33 is slidably connected to the top surface of the support plate 31, and the bottom surface of the sliding table 33 is connected to the telescopic part on the translational force device 32 via a connector 4.

[0027] In use, the translational force device 32 can drive the sliding table 33 to move horizontally on the support plate 31, thereby facilitating loading and unloading. When the sliding table 33 is under load, the force it receives is distributed to multiple support plates 31. When the sliding table 33 undergoes slight deformation due to the large weight of the material it is carrying, the sliding table 33 can still move horizontally on the support plate 31.

[0028] In a further optimized design, the bottom surface of the support plate 31 is provided with a slot 5 that is adapted to connect with the bottom crossbeam 102. The slot 5 enables a detachable connection between the support plate 31 and the bottom crossbeam 102, while ensuring the stability of the connection between the support plate 31 and the bottom crossbeam 102.

[0029] In a further preferred embodiment, the connecting member 4 includes a connecting plate 41 and a transmission rod 42. The top end of the connecting plate 41 is fixedly connected to the sliding table 33, and the bottom end of the connecting plate 41 is provided with a transmission groove 43. The transmission rod 42 is fixedly connected to the end of the telescopic part on the translational power device 32, and the transmission rod 42 horizontally passes through the transmission groove 43. In use, when the telescopic part moves, it drives the transmission rod 42 to move, the transmission rod 42 drives the connecting plate 41 to move, and the connecting plate 41 drives the sliding table 33 to move.

[0030] In a further preferred embodiment, the frame 1 includes a top crossbeam 101, a bottom crossbeam 102, and two support plates 103. Both the top crossbeam 101 and the bottom crossbeam 102 are channel-shaped beams with their openings facing upwards. The two side walls of the bottom crossbeam 102 along the length of the support plate 31 are the first side wall and the second side wall, respectively. The two side walls of the top crossbeam 101 along the length of the support plate 31 are the third side wall and the fourth side wall, respectively. The top and bottom ends of the support plates 103 are fixedly connected to the top crossbeam 101 and the bottom crossbeam 102, respectively, and the fixed connection can be welding. A first fixing pin 6 is provided between the support plate 103 and the top crossbeam 101. The first fixing pin 6 passes through the third and fourth side walls, and both ends of the first fixing pin 6 are fixedly connected to the support plate 103. A second fixing pin 7 is provided between the support plate 103 and the bottom crossbeam 102. The second fixing pin 7 passes through the first and second side walls, and both ends of the second fixing pin 7 are fixedly connected to the support plate 103.

[0031] In use, the first fixing pin 6 and the second fixing pin 7 can increase the overall strength of the frame 1, thereby ensuring the overall service life of the gantry press.

[0032] In a further optimized design, several reinforcing plates 8 are fixedly connected between the third and fourth side walls. The reinforcing plates 8 can increase the overall strength of the frame 1, thereby ensuring the overall service life of the gantry press.

[0033] In a further preferred embodiment, the pressure head assembly 2 includes a hydraulic cylinder 201 fixed to the bottom surface of the top crossbeam 101, with the telescopic end of the hydraulic cylinder 201 connected to the pressure head 202. In use, the hydraulic cylinder 201 drives the pressure head 202 downwards to process the workpiece, and then the hydraulic cylinder 201 drives the pressure head 202 upwards to reset.

[0034] Further optimization of the design: the translational power device 32 is a double-headed hydraulic cylinder 201. The double-headed hydraulic cylinder 201 can drive the sliding table 33 to translate in two directions, so that loading and unloading can be performed on both sides of the gantry press.

[0035] Therefore, the gantry press of this utility model with the above structure can facilitate loading and unloading by moving the sliding table 33, and can effectively solve the problem that the sliding table 33 cannot move normally after bending and deforming due to excessive load.
