DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a position-limiting extension mechanism, comprising a die base 101 and a floating material plate 102 disposed above the die base 101, a material sheet 2 is placed above the floating material plate 102, and also comprises a floating support component disposed between the die base 101 and the floating material plate 102 for floating and supporting the placed material sheet 2;

[0021] The floating support assembly includes a mounting hole 301 formed on the floating plate 102, a fixing plate 302 is fixed inside the mounting hole 301, a support rod 303 is slidably connected to the fixing plate 302, a support plate 304 is fixed to the upper end of the support rod 303, and the other end of the support rod 303 is fixed to the mold base 101 by means of threads, and a limit extension assembly for limit extension during the floating support process is provided below the floating plate 102;

[0022] It should be noted here that: when the sheet 2 in the auxiliary stamping process is supporting the material removal operation, the floating plate 102 is pushed toward the die base 101. During the pushing process, the support rod 303 slides on the fixed plate 302. During the sliding process, the support plate 304 at the upper end of the support rod 303 is abutted against the lower end of the sheet 2. Through the abutment, the sheet 2 is floated and supported to assist the material removal operation of the sheet 2 after stamping. In the process of floating support, the extension plate 402 set under the floating plate 102 is abutted against the die base 101 to limit the continuous descent of the floating plate 102, so as to avoid the continuous descent of the floating plate 102 causing the sheet 2 to be continuously floated and supported and collide with the objects in the upper space to cause damage, which is convenient for the subsequent stable use of the sheet 2.

[0023] Two groups of floating support components are symmetrically arranged between the mold base 101 and the floating plate 102;

[0024] It should be noted here that: by using two groups of symmetrically arranged floating support components, it is convenient to float and support the sheet 2 more stably.

[0025] The limit extension assembly includes a mounting plate 401, which is mounted below the floating plate 102 through the mounting assembly. An extension plate 402 for stroke control during the floating support process is arranged below the mounting plate 401, and a telescopic adjustment assembly for telescopically adjusting the extension plate 402 is arranged on the mounting plate 401;

[0026] It should be noted here that: in the process of supporting the floating sheet 2 by the descending of the floating plate 102, the extension plate 402 arranged under the floating plate 102 is abutted against the mold base 101, so as to limit the continuous descent of the floating plate 102, so as to avoid the continuous descent of the floating plate 102 causing the sheet 2 to be continuously floated and supported and collide with objects in the upper space to be damaged, so as to facilitate the subsequent stable use of the sheet 2.

[0027] The telescopic adjustment assembly includes a threaded sleeve 501 fixed on the mounting plate 401, a threaded rod 502 is threadedly engaged on the threaded sleeve 501, one end of the threaded rod 502 is rotatably connected to the extension plate 402, and a driving pin 503 is fixed to the other end of the threaded rod 502. A plurality of groups of T-shaped rods 504 are slidably connected to the mounting plate 401, and one end of each group of T-shaped rods 504 is fixed to the extension plate 402;

[0028] It should be noted here that: the threaded rod 502 is driven to rotate by the driving pin 503. During the rotation of the threaded rod 502, the mutual meshing transmission between the threaded rod 502 and the threaded sleeve 501 and the sliding guiding effect of the multiple groups of T-bars 504 enable the extension plate 402 to move toward or away from the mounting plate 401 after being subjected to force.

[0029] The mounting assembly includes two sets of mounting seats 601, the mounting plate 401 is fixed between the two sets of mounting seats 601, a sliding hole 602 is opened on the mounting seat 601, and the mounting seat 601 is sleeved on the outer side of the support rod 303 under the action of the sliding hole 602, and the mounting seat 601 and the lower end of the floating plate 102 are detachably mounted by bolts;

[0030] It should be noted here that: the mounting seat 601 is sleeved on the outside of the support rod 303 through the sliding hole 602. After the sleeve is completed, the mounting seat 601 is installed under the floating plate 102 by bolts, and the auxiliary mounting plate 401 is installed and connected under the floating plate 102.

[0031] The outer sides of the two groups of support rods 303 are sleeved with springs 7, and the two ends of the springs 7 are connected to the mold base 101 and the mounting base 601 respectively;

[0032] It should be noted that when the floating plate 102 moves toward the mold base 101 , the spring 7 is compressed and deformed by the mounting base 601 to generate elastic force, and the elastic force of the spring 7 assists the subsequent reset movement of the floating plate 102 .

[0033] Working principle: When the sheet 2 in the auxiliary stamping process is supported and removed, the floating plate 102 is pushed toward the die base 101. During the pushing process, the support rod 303 slides on the fixed plate 302. During the sliding process, the support plate 304 at the upper end of the support rod 303 abuts against the lower end of the sheet 2. Through the abutment, the sheet 2 is floated and supported, and the stripping operation of the sheet 2 after the stamping is assisted;

[0034] In the process of floating the material sheet 2 by the floating plate 102 descending, the extension plate 402 arranged below the floating plate 102 abuts against the mold base 101, and the continuous descent of the floating plate 102 is limited, so as to prevent the continuous descent of the floating plate 102 from causing the material sheet 2 to be continuously floated and supported and collide with the object in the upper space position to be damaged, so as to facilitate the subsequent stable use of the material sheet 2;

[0035] And in the process of extension and limiting, by adjusting the component, the extension plate 402 can move toward or away from the mounting plate 401, and the distance between the extension plate 402 and the floating plate 102 can be adjusted. By adjusting the distance, the floating plate 102 can be limited at different positions during the movement toward the mold base 101, which further facilitates more flexible control of the maximum height of the floating support of the sheet 2, and facilitates the flexible operation and use of the extension limit component.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
