DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1-8 A high-precision hydraulic punch press for aluminum alloy profiles. In order to help the aluminum alloy sheet stabilize the plate body during stamping, form a progressive extrusion lock of the stamping parts from top to bottom, and extend the service life of the locking structure, a stamping base bed 1 and a synchronous locking structure 5 are arranged here, wherein a stamping assembly 2 for stamping is arranged above the stamping base bed 1, and the stamping assembly 2 includes a stamping slider 201, and the stamping slider 201 is facing the stamping base bed 1 below. An ejection assembly 3 for ejecting the stamped aluminum alloy profile is arranged at the bottom end of the inner side of the stamping base bed 1. The ejection assembly 3 is a mechanism for ejecting by a cylinder, which will not be described here. A top locking mechanism 4 for inserting and locking the aluminum alloy profile is arranged on the stamping base bed 1.

[0020] The synchronous locking structure 5 includes a synchronous lifting component 51 and an extrusion locking component 52. The synchronous lifting component 51 includes a synchronous lifting plate 512. The synchronous lifting plate 512 is arranged on the stamping slider 201. The extrusion locking component 52 is arranged below the synchronous lifting plate 512, and the extrusion locking component 52 is facing the stamping base bed 1. One side plate of the synchronous lifting plate 512 is located directly above the top-level locking mechanism 4, and the synchronous lifting plate 512 is connected to the top-level locking mechanism 4. When the synchronous lifting plate 512 descends, it will act on the top-level locking mechanism 4 to form a further extrusion locking of the top-level locking mechanism 4, thereby helping the top-level locking mechanism 4 to lock the aluminum alloy profile on the stamping base bed 1.

[0021] The extrusion locking assembly 52 includes an extrusion locking bottom ring 521, an extrusion spring 522 and a counter-stabilizing assembly 6. The extrusion locking bottom ring 521 is arranged below the synchronous lifting plate 512, and the extrusion spring 522 is arranged between the extrusion locking bottom ring 521 and the synchronous lifting plate 512, so that when the stamping slide 201 and the synchronous lifting plate 512 are lowered, the extrusion locking bottom ring 521 first contacts the aluminum alloy profile on the stamping base bed 1, thereby compressing the extrusion spring 522. At this time, the extrusion locking bottom ring 521 will squeeze the aluminum alloy profile close to the stamping base bed 1 to lock the aluminum alloy profile. At this time, when the stamping slide 201 continues to move downward, the stamping of the aluminum alloy profile will be completed. Figure 4 and Figure 7As shown, an inner liner shaft column is provided on the inner side of the extrusion spring 522 for preventing the extrusion spring 522 from bending, which can prevent the extrusion spring 522 from bending and being damaged during the compression process. The opposing stabilizing component 6 is arranged between the edge of the extrusion locking bottom ring 521 and the synchronous lifting plate 512. The opposing stabilizing component 6 forms an opposing inclined support and extrusion for the extrusion locking bottom ring 521. Due to the limitations of the material and shape of the extrusion spring 522, when the extrusion locking bottom ring 521 deviates left or right, the extrusion spring 522 is prone to horizontal bending deformation, thereby causing the extrusion direction of the extrusion locking bottom ring 521 to change, affecting the stability during stamping. The opposing stabilizing structure is formed between the edge of the extrusion locking bottom ring 521 and the synchronous lifting plate 512 by the opposing stabilizing component 6, which can avoid lateral deviation of the extrusion locking bottom ring 521, thereby preventing the extrusion spring 522 from bending and deformation.

[0022] like Figure 4 As shown, the extrusion locking assembly 52 is arranged on both sides below the synchronous lifting plate 512 and distributed on both sides of the stamping slider 201. It can form a symmetrical extrusion locking structure on both sides of the stamping slider 201, which is convenient for increasing the stability of extrusion when the extrusion locking of the extruded aluminum alloy sheet is completed.

[0023] The opposing stabilization component 6 includes a positioning rail 601, a compression spring 602 and a synchronous lifting frame 603. The positioning rail 601 is vertically arranged at the bottom end of the synchronous lifting plate 512. The positioning rail 601 is provided with a guide groove along the length direction of the positioning rail 601. The compression spring 602 is arranged on the inner side of the guide groove of the positioning rail 601. One end of the synchronous lifting frame 603 is slidably installed in the guide groove of the positioning rail 601 and is connected to the compression spring 602, and the other end is connected to the edge of the extrusion locking bottom ring 521.

[0024] Among them, the opposing stabilizing components 6 are arranged at the four side edges of the extrusion locking bottom ring 521, so that the four opposing stabilizing components 6 form a four-way opposing extrusion on the extrusion locking bottom ring 521, helping to stabilize the extrusion locking bottom ring 521.

[0025] The extrusion locking bottom ring 521 includes a cross connecting frame and an extrusion ring plate arranged at the bottom end of the cross connecting frame, wherein the synchronous lifting frame 603 is respectively connected to the four corners of the cross connecting frame, so that the opposite stabilizing component 6 can form an opposite extrusion on the cross connecting frame, thereby forming an opposite stabilizing structure between the cross connecting frame of the extrusion locking bottom ring 521 and the synchronous lifting plate 512; Wherein, a soft cushion ring is arranged at the bottom end of the extrusion ring plate for preventing hard friction.

[0026] The synchronous lifting assembly 51 also includes a limiting vertical shaft 511, which is distributed in groups of four on the four sides of the stamping base bed 1, and the four limiting vertical shafts 511 pass through the four corners of the synchronous lifting plate 512 respectively, so that the four limiting vertical shafts 511 can play a role in stably guiding and limiting the lifting and lowering of the synchronous lifting plate 512 and the stamping slider 201.

[0027] The stamping assembly 2 also includes a basic base 202 and a stamping drive assembly 203. The basic base 202 is an L-shaped base. The stamping drive assembly 203 is arranged at the end of the vertical plate body of the basic base 202. The stamping drive assembly 203 is a hydraulic cylinder structure, which will not be described here. The stamping slider 201 is arranged on the output end of the stamping drive assembly 203, so that the stamping drive assembly 203 can drive the stamping slider 201 and the synchronous lifting plate 512 to move up and down along the limiting vertical axis 511 to stamp the aluminum alloy profile placed on the stamping base bed 1 directly below the stamping slider 201.

[0028] Blocking side seats 7 are arranged on both sides of the stamping base bed 1, and slots that fit the top surface of the stamping base bed 1 are opened on the blocking side seats 7. The slots of the two blocking side seats 7 are in corresponding positions. Through the slots of the two blocking side seats 7 that are directly opposite to each other, the two sides of the aluminum alloy plate can be fitted into the two slots and slid into the stamping base bed 1 for positioning. The slots of the blocking side seats 7 are used to limit the side edges of the aluminum alloy plate. The top locking mechanism 4 includes an inserted locking piece 41 and an extruded connecting piece 42. The inserted locking piece 41 includes a locking stand 411. A plurality of locking stands 411 are arranged in parallel as a group. A plurality of locking frames 411 vertically penetrate the shielding side seat 7, and the bottom end of the locking frame 411 is located in the slot of the shielding side seat 7, the extrusion connecting piece 42 is arranged at the end of the locking frame 411, and the extrusion connecting piece 42 is located below one side of the synchronous lifting plate 512, so that when the synchronous lifting plate 512 moves downward, it can extrude the extrusion connecting piece 42 and further extrusion the locking frame 411, so that the locking frame 411 is subjected to a downward and progressively increasing extrusion force, which helps the locking frame 411 to better extrude and lock the edge of the aluminum alloy plate inserted into the shielding side seat 7.

[0029] The locking stand 411 includes a slide bar slidably mounted on the shielding side seat 7 in the vertical direction and an extrusion block arranged at the bottom end of the slide bar. The side of the extrusion block facing the stamping base bed 1 is an arc edge. The slot shape of the shielding side seat 7 is as follows: Figure 6 As shown, the extrusion block portion of the locking stand 411 is arranged in contact with the inner wall of the slot, so that the extrusion block can move up and down under the guidance of the slot, thereby ensuring the stability of the locking stand 411 when moving up and down.

[0030] Furthermore, the top-level locking mechanism 4 further comprises a return spring 412, which is arranged around the outside of the slide bar of the locking stand 411, and one end of the return spring 412 is connected to the top wall of the shielding side seat 7, and the other end is connected to the end of the slide bar of the locking stand 411, so that when the slide bar portion of the locking stand 411 moves upward, the return spring 412 will act on the slide bar portion of the locking stand 411, so that the slide bar maintains a downward movement trend. When the side is inserted into the slot of the shielding side seat 7, the aluminum alloy plate will squeeze the arc edge of the extrusion block of the locking frame 411, thereby squeezing the sliding rod part of the locking frame 411 to move upward. At this time, under the action of the return spring 412, the sliding rod keeps moving downward and squeezes the aluminum alloy plate through the extrusion block, forming a lock for the aluminum alloy plate in the slot of the shielding side seat 7. The return spring 412 provides a force to press the locking frame 411 downward, helping the locking frame 411 to squeeze the aluminum alloy plate in the slot of the shielding side seat 7 as soon as possible.

[0031] The extrusion connector 42 includes a force-bearing top plate 421, a telescopic spring 422 and a through-plate shaft 423. The force-bearing top plate 421 is arranged at the top of the plurality of locking stands 411. A through slot is provided on the force-bearing top plate 421. The through-plate shaft 423 is arranged at the lower end of the synchronous lifting plate 512, and the bottom end of the through-plate shaft 423 passes through the through slot of the force-bearing top plate 421. The telescopic spring 422 is arranged between the force-bearing top plate 421 and the synchronous lifting plate 512, and the telescopic spring 422 surrounds the outside of the through-plate shaft 423. Figure 8 As shown, the through-plate shaft 423 is a retractable shaft, and the through-plate shaft 423 on the inner side of the retractable spring 422 can prevent the retractable spring 422 from bending. When the through-plate shaft 423 passes through the through-slot and continues to move downward, it will squeeze the shielding side seat 7. At this time, the through-plate shaft 423 contracts, thereby avoiding hard contact between the through-plate shaft 423 and the shielding side seat 7.

[0032] Among them, Figure 4 As shown, the lower ends of both sides of the synchronous lifting plate 512 are provided with through-plate shafts 423, and the through-plate shafts 423 on both sides correspond to the locking brackets 411 and the force-bearing top plates 421 on the two shielding side seats 7, respectively, and the through grooves on the force-bearing top plates 421 correspond one by one to the through-plate shafts 423, as shown in FIG. Figure 8As shown, the through-plate shafts 423 and the telescopic springs 422 are distributed in parallel above the stressed top plate 421 as a group, and the multiple through-plate shafts 423 and the multiple locking frames 411 are staggered on the upper and lower sides of the stressed top plate 421. At the same time, the multiple telescopic springs 422 and the return springs 412 are also staggered on the upper and lower sides of the stressed top plate 421. When the synchronous lifting plate 512 moves downward, the multiple through-plate shafts 423 move downward in the through-grooves of the stressed top plate 421. At this time, the telescopic springs 422 on the outer sides of the multiple through-plate shafts 423 are squeezed, which will form a multi-point squeeze on the stressed top plate 421. At the same time, the multiple locking frames 411 below the stressed top plate 421 will, under the action of the return springs 412, use the locking frames 412 to The bottom extrusion block 1 squeezes the aluminum alloy sheet on the stamping base bed 1. Due to the staggered distribution of the telescopic springs 422 and the return springs 412, uniform force can be formed on the locking stand 411 and the force-bearing top plate 421, so that multiple locking stands 411 act evenly on the aluminum alloy sheet on the stamping base bed 1, forming a stable and uniform extrusion locking of the edge of the aluminum alloy sheet. At the same time, since the telescopic springs 422 and the return springs 412 have a certain degree of telescopic elasticity, when the aluminum alloy sheet is stamped, it is extended and deflected and acts on the locking stand 411. Through the transition and buffering of the telescopic springs 422 and the return springs 412, the impact on the locking stand 411 and the force-bearing top plate 421 can be reduced.

[0033] After the aluminum alloy sheet is inserted into the slot of the shielding side seat 7, the side of the aluminum alloy sheet can be shielded by the shielding side seat 7, and the synchronous locking structure 5 is positioned by squeezing the center position of the aluminum alloy sheet from top to bottom, and the top-level locking mechanism 4 is positioned by squeezing the edge position of the aluminum alloy sheet from top to bottom. Through the mutual cooperation of the synchronous locking structure 5 and the top-level locking mechanism 4 during the downward movement of the synchronous lifting plate 512, the aluminum alloy sheet can be subjected to uniform force from top to bottom and squeezed and locked in position on the stamping base bed 1 during the stamping process. In this locked state, the aluminum alloy sheet will not be able to impact the locking structures such as the synchronous locking structure 5 and the top-level locking mechanism 4 when it is extended and deflected, thereby reducing the impact on the locking structure and extending the service life of the synchronous locking structure 5 and the top-level locking mechanism 4.

[0034] Working principle: insert the aluminum alloy sheet into the slots of the two shielding side seats 7 in close contact with the top surface of the stamping base bed 1. During the insertion process, the aluminum alloy sheet will squeeze the arc edge of the extrusion block at the bottom end of the locking frame 411 during the forward movement, thereby squeezing the locking frame 411 upward, and the locking frame 411 will be squeezed above the edge of the aluminum alloy sheet in the slot of the shielding side seat 7 under the action of the return spring 412, thereby forming an extrusion on the edge of the aluminum alloy sheet, and the shielding side seat 7 blocks the edge of the aluminum alloy sheet. At this time, start the stamping drive component 203 to drive the stamping slider 201 and the synchronous lifting plate 512 to move downward and stamp the aluminum alloy sheet. During the descent of the synchronous lifting plate 512, The multiple plate-penetrating shafts 423 below the two sides of the synchronous lifting plate 512 will respectively move downward in the multiple grooves of the force-bearing top plate 421. At this time, the telescopic springs 422 outside the plate-penetrating shafts 423 are squeezed, which will form a multi-point squeezing of the force-bearing top plate 421, and the force-bearing top plate 421 is connected to a plurality of locking stands 411 below. At this time, the locking stands 411 and the force-bearing top plate 421 will be under the action of the staggered telescopic springs 422 and the return springs 412, so that the bottom ends of the multiple locking stands 411 further act on the aluminum alloy plate on the stamping base bed 1, forming a multi-point, uniform and stable squeezing and locking of the edges of the two sides of the aluminum alloy plate. As the telescopic springs 422 and the return springs 412 descend with the synchronous lifting plate 512 The compression process is progressive, so that the extrusion force of the locking frame 411 on the aluminum alloy plate is also progressively increased, so that the closer the stamping slider 201 and the synchronous lifting plate 512 are to the aluminum alloy plate, the greater the extrusion locking force on the edge of the aluminum alloy plate. At the same time, as the stamping slider 201 and the synchronous lifting plate 512 continue to move downward, the extrusion locking bottom ring 521 will contact the aluminum alloy plate. As the stamping slider 201 and the synchronous lifting plate 512 continue to move downward, the extrusion locking bottom ring 521 will squeeze the extrusion spring 522 to be compressed. At the same time, the synchronous lifting frames 603 at the four corners of the extrusion locking bottom ring 521 will squeeze the compression spring 602 in the positioning vertical rail 601 to compress it. 02 and the reverse force generated when the extrusion spring 522 is compressed can squeeze the extrusion locking bottom ring 521 and the aluminum alloy plate, so that the aluminum alloy plate fits on the top surface of the stamping base bed 1, and the locking stands 411 on the two shielding side seats 7 respectively squeeze the two side edges of the aluminum alloy plate, and at the same time, the extrusion locking components 52 on both sides of the stamping slider 201 form a symmetrical extrusion lock on the middle part of the aluminum alloy plate, thereby extruding and locking the entire aluminum alloy plate in all directions and from top to bottom. Different from the ordinary edge locking structure, this top-down extrusion locking structure can avoid the impact of the aluminum alloy plate on the locking structure when it is extended and offset during the stamping process, thereby extending the service life of the locking structure.
