Description

Technical Field

[0001] This utility model relates to the field of pressing machine technology, and specifically to a pressing machine that facilitates fixture replacement. Background Technology

[0002] A pressing machine (also called a stamping press or punching press) for aluminum sheet processing is a core piece of equipment that uses powerful mechanical or hydraulic force to plastically deform aluminum sheets through matching molds. Its core function is to place a flat aluminum sheet between molds and force it to undergo permanent deformation under precisely controlled, enormous pressure (ranging from tens to thousands of tons), thereby manufacturing parts or products of specific shapes, sizes, and precision. Based on the power source, they are mainly divided into mechanical pressing machines and hydraulic pressing machines: mechanical machines are generally faster and suitable for mass production of blanking and shallow drawing; hydraulic machines provide more stable, adjustable pressure with a larger stroke, and are particularly suitable for deep drawing, precision forming, embossing, and leveling processes.

[0003] Chinese utility model patent CN221133719U discloses an aluminum plate processing pressing machine, which includes "a worktable, a control box, a shock absorption component, a material discharge guide component, a pressing component, a directional installation component, a material removal component, and a positioning and reinforcement component"; however, the fixture installation in this device is quite cumbersome, and in the actual aluminum plate processing process, the requirement for fixture replacement is very frequent in order to adapt to the processing needs of aluminum plates of different shapes and sizes. Utility Model Content

[0004] The purpose of this invention is to provide a pressing machine that facilitates fixture replacement, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing machine that facilitates fixture replacement, comprising a device frame, a transmission assembly inside the device frame, and a clamping assembly on the upper part of the transmission assembly; the device frame includes a worktable, an upper frame on the upper part of the worktable, and the worktable and the upper frame are connected by four limiting rods; the transmission assembly includes a dual-head servo motor, the base of which is connected to the worktable by bolts; the clamping assembly includes two sliding members, each of which has a return spring fixedly installed inside, and a slidable clamping member inside each of which has a limiting block fixedly installed at the front end of the clamping member; a clamping tool is provided inside the sliding member, and a limiting groove is formed at the rear end of the clamping tool, with the limiting block and the limiting groove engaging for limiting.

[0006] The beneficial effects of this utility model are as follows: by grasping the handle and pulling the clamping part backward, the return spring is compressed backward, causing the limiting block to disengage from the limiting groove, the clamping tool can be taken out for replacement, and then other overtime tools can be installed. When the handle is released, the return spring rebounds, causing the limiting block to insert into the limiting groove and hold the new clamping tool. This achieves the effect of quickly changing the clamp during use, improving the replacement efficiency and increasing the practicality of the device.

[0007] To achieve independent rotation of the threaded rod:

[0008] The worktable is further configured such that sliding grooves are provided on both sides of its inner wall, and bearings are rotatably mounted on both sides of the worktable.

[0009] By adopting the above technical solution and setting bearings on both sides, the threaded rotating rods on both sides can rotate inside the worktable without being affected, which facilitates the use of subsequent devices.

[0010] To achieve the pressing of the aluminum plate:

[0011] The upper part of the upper frame is further configured such that a hydraulic pump is slidably mounted on the upper end, a piston rod is slidably mounted on the lower end of the hydraulic pump, a pressing mold is slidably mounted on the lower part of the piston rod, and the pressing mold is connected to the piston rod by bolts.

[0012] By adopting the above technical solution, the hydraulic pump is started, and the piston rod pushes the pressing mold down to press the aluminum plate into shape. Then, the piston rod drives the pressing mold up to remove the pressed aluminum plate.

[0013] To enable the movement of the clamping components on both sides:

[0014] The configuration is further defined as follows: threaded rotors are rotatably mounted on both sides of the dual-head servo motor, a connecting block is slidably mounted on the outer surface of each threaded rotor, and a threaded hole is opened inside each connecting block.

[0015] By adopting the above technical solution, the dual-head servo motor is started, which drives the threaded rotating rods on both sides to rotate, thereby driving the connecting blocks on both sides to move. Since the sliding parts are fixedly installed on the connecting blocks, they will move synchronously, and finally the aluminum plate is used for clamping and limiting.

[0016] To enable the clamping assembly to slide inside the worktable:

[0017] The further configuration is as follows: each of the sliding members has a slider fixedly installed on both sides, and the upper end of the collateral member has a handle fixedly installed.

[0018] By adopting the above technical solution, the sliders on both sides of the sliding member are set inside the sliding groove, so that the clamping assembly moves along the set track and the aluminum plate is clamped in the accurate position.

[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] Please see Figures 1 to 5 A press machine with easy fixture replacement includes a device frame 1, a transmission assembly 2 inside the device frame 1, and a clamping assembly 3 on the upper part of the transmission assembly 2; the device frame 1 includes a worktable 11, and an upper frame 12 on the upper part of the worktable 11, and the worktable 11 and the upper frame 12 are connected by four limiting rods; the transmission assembly 2 includes a dual-head servo motor 21, and the base of the dual-head servo motor 21 is connected to the worktable 11 by bolts; the clamping assembly 3 includes two sliding parts 31, each sliding part 31 has a return spring 38 fixedly installed inside, each sliding part 31 has a slidable clamping part 33 inside, the front end of the clamping part 33 is fixedly installed with a limiting block 35, the sliding part 31 has a clamping tool 36 inside, the rear end of the clamping tool 36 has a limiting groove 37, and the limiting block 35 is inserted into the limiting groove 37 for limiting.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the inner walls of the worktable 11 are provided with sliding grooves 16 on both sides, and bearings 17 are rotatably installed on both sides of the worktable 11.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, a hydraulic pump 13 is slidably mounted on the upper end of the upper frame 12, a piston rod 14 is slidably mounted on the lower end of the hydraulic pump 13, and a pressing mold 15 is slidably mounted on the lower part of the piston rod 14. The pressing mold 15 and the piston rod 14 are connected by bolts.

[0030] In this embodiment, as Figure 1 and Figure 3 As shown, threaded rods 22 are rotatably mounted on both sides of the dual-head servo motor 21. A connecting block 23 is slidably mounted on the outer surface of each threaded rod 22, and a threaded hole 24 is opened inside each connecting block 23.

[0031] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, each sliding member 31 has a slider 32 fixedly installed on both sides, and a handle 34 fixedly installed on the upper end of the collateral member 33.

[0032] The pressing machine, which facilitates fixture replacement, operates as follows:

[0033] First, start the dual-head servo motor 21 (model: HG-KR73J-S100) to drive the threaded rotating rods 22 on both sides to rotate, causing the connecting blocks 23 on both sides to move the sliding member 31 above. The sliding member 31 is limited by the sliders 32 on both sides. When the sliding member 31 moves to the appropriate position, the aluminum plate to be pressed is overlapped between the two clamping tools 36. Next, start the dual-head servo motor 21 to clamp the aluminum plate. Then, start the hydraulic pump 13 to make hydraulic oil enter the hydraulic cylinder to push the piston rod 14 and the pressing mold 15 down to press the aluminum plate below. After pressing, start the dual-head servo motor 21 again. Separate the clamping tools 36 on both sides to remove the pressed aluminum plate. When it is necessary to change the clamping tools 36 to adapt to the processing needs of aluminum plates of different shapes, simply grasp the handles 34 on both sides and pull them backward. At this time, the return spring 38 (model: SL101) will be compressed backward. After the limit block 35 separates from the limit groove 37, the clamping tool 36 can be removed. Then, replace it with a clamping tool 36 of a new shape, insert it into the mortise 33, and release the handles 34. At this time, the return spring 38 will rebound, and the limit block 35 will be inserted into the limit groove 37 again, holding the clamping tool 36 in place. Then, the above operation can be repeated to press aluminum plates with different requirements.
