[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the required parts. However, during the production process, due to the structural characteristics of the product to be stamped, continuous stamping actions cannot be performed, and only separate stamping actions can be performed. However, in order to prevent the workpiece from shifting due to the impact force of the equipment during the stamping process, resulting in unqualified stamped workpieces, it is necessary to manually support the workpiece.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0027] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a metal parts stamping die, which includes a main body component 100 and a feeding component 200. Through the cooperation of the two, the workpiece 205 can be sent to the specified stamping position and the workpiece 205 can be fixed, so that the staff does not need to support the workpiece 205, thereby avoiding damage to the staff. After the stamping is completed, the excess scraps can be automatically removed from the stamping die.

[0028] Specifically, the main assembly 100 includes a support platform 101 , a positioning column 102 and a stamping part 103 . The positioning column 102 is fixed on the top of the support platform 101 , and the stamping part 103 is arranged on the surface of the positioning column 102 .

[0029] The support platform 101 is used to fix and support the positioning column 102 , the positioning column 102 is used to limit the position of the stamping part 103 , and the stamping part 103 is used to stamp the workpiece to obtain the required metal parts.

[0030] The feeding assembly 200 is arranged on the stamping part 103, and includes a lifting part 201, a telescopic part 202, a positioning part 203, a limiting part 204 and a workpiece 205. The lifting part 201 is arranged in the stamping part 103, the telescopic part 202 is located in the lifting part 201, the positioning part 203 is arranged in the telescopic part 202, and the limiting part 204 is located in the stamping part 103.

[0031] The lifting member 201 is used to support the feeding assembly 200, and the setting of the lifting member 201 can separate the scraps and the stamped metal parts after the workpiece 205 is stamped by the stamping member 103. The telescopic member 202 is used to move the workpiece 205 to a designated position to be stamped, and at the same time, the stamped scraps can be removed. The positioning member 203 is used to fix the position of the workpiece 205, thereby preventing the workpiece 205 from shifting during the stamping process. The limit member 204 is used to limit the position of the telescopic member 202. When the stamping is completed, the limit member 204 can release the limit on the telescopic member 202, so that the telescopic member 202 drives the scraps to move out of the stamping member 103.

[0032] Specifically, the stamping part 103 includes a lower die 103 a and an upper die 103 b . The lower die 103 a is fixed on the top of the support platform 101 , and the upper die 103 b slides on the surface of the positioning column 102 .

[0033] The lower die 103 a is used to support the feeding assembly 200 , and the upper die 103 b can punch out the required metal parts from the workpiece 205 by cooperating with the lower die 103 a .

[0034] Specifically, the lifting member 201 includes a lifting sleeve 201a and a first spring 201b. The lifting sleeve 201a slides in the lower mold 103a, and two ends of the first spring 201b are respectively fixed to the inner wall of the lifting sleeve 201a and the inner wall of the lower mold 103a.

[0035] The first spring 201b is in a compressed state. The lifting sleeve 201a can be pushed by the restoring elastic force of the first spring 201b, so that the lifting member 201 can move up and down in the lower mold 103a.

[0036] Specifically, the lifting member 201 further includes a support column 201c and a limiting shell 201d. Both ends of the support column 201c are respectively fixed to the top of the lifting sleeve 201a and the bottom of the limiting shell 201d. The limiting shell 201d slides in the lower mold 103a.

[0037] When the upper die 103b squeezes the lower die 103a, the upper die 103b will first squeeze the limiting shell 201d, so that the limiting shell 201d squeezes the first spring 201b through the support column 201c and the lifting sleeve 201a, thereby causing the first spring 201b to contract. After the upper die 103b and the lower die 103a punch the workpiece 205, the upper die 103b moves upward. At this time, under the action of the restoring elastic force of the first spring 201b, the limiting shell 201d can be driven to move upward. Example 2

[0038] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the telescopic member 202 includes a support block 202a, a second spring 202b, a telescopic plate 202c and a handle 202d. The support block 202a is fixed to the inner wall of the limiting shell 201d, and the two ends of the second spring 202b are respectively fixed to one side of the support block 202a and the inner wall of the telescopic plate 202c. The telescopic plate 202c slides in the limiting shell 201d, and the handle 202d is fixed to the end of the telescopic plate 202c.

[0040] The support block 202a is used to support the second spring 202b, and the second spring 202b is in a normal state. The telescopic plate 202c is used to carry the workpiece 205. The telescopic plate 202c can be moved by pushing the handle 202d, so that the telescopic plate 202c stretches the second spring 202b, so that the workpiece 205 on the top of the telescopic plate 202c is sent between the lower mold 103a and the upper mold 103b.

[0041] Specifically, the positioning member 203 includes a limiting plate 203a and a limiting strip 203b. The limiting plate 203a is fixed to the top of the limiting shell 201d by bolts, and the limiting strip 203b is fixed to the end of the limiting plate 203a, and the limiting strip 203b is located on the surface of the telescopic plate 202c.

[0042] The limiting plate 203a is used to limit the position of the workpiece 205 to prevent the workpiece 205 from detaching from the telescopic plate 202c. The limiting strip 203b is used to limit the workpiece 205 so that the workpiece 205 moves to the bottom of the limiting plate 203a. When the workpiece 205 moves to the bottom of the limiting plate 203a, both sides of the workpiece 205 will be squeezed by one side of the limiting shell 201d, thereby limiting the position of the workpiece 205.

[0043] Specifically, the positioning member 203 also includes a push block 203c, an extrusion block 203d, a positioning rod 203e and a third spring 203f. The push block 203c is fixed to the top of the telescopic plate 202c, the extrusion block 203d slides in the telescopic plate 202c, the positioning rod 203e is fixed to one side of the extrusion block 203d, and the two ends of the third spring 203f are respectively fixed to the end of the positioning rod 203e and the inner wall of the telescopic plate 202c.

[0044] The push block 203c is used to push the workpiece 205 to prevent the workpiece 205 from slipping on the telescopic plate 202c and being unable to move to the bottom of the limit plate 203a. When the telescopic plate 202c moves into the limit shell 201d, as the telescopic plate 202c moves, the positioning rod 203e will squeeze the inner wall of the limit shell 201d, so that the positioning rod 203e squeezes the third spring 203f, thereby compressing the third spring 203f. At this time, the positioning rod 203e drives the extrusion block 203d to move toward the workpiece 205. Since the length of the positioning rod 203e is fixed, the limiting position of the extrusion block 203d on the workpiece 205 is fixed. Through the joint limiting of the extrusion block 203d and the push block 203c, the workpiece 205 is fixed at the specified stamping position. Example 3

[0045] Reference Figure 2~Figure 5 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0046] Specifically, the limiting member 204 includes a limiting sleeve 204a, a fourth spring 204b and a limiting pin 204c. The limiting sleeve 204a is fixed in the limiting shell 201d. The two ends of the fourth spring 204b are respectively fixed to the inner wall of the limiting sleeve 204a and the bottom of the limiting pin 204c. The limiting pin 204c slides in the limiting sleeve 204a. A limiting groove U is provided on the telescopic plate 202c, and the limiting pin 204c can be inserted into the limiting groove U.

[0047] The limiting sleeve 204a is used to limit the limiting pin 204c, the fourth spring 204b is in a compressed state, and an inclined surface is provided on the top of the limiting pin 204c. When the telescopic plate 202c moves into the limiting shell 201d, the end of the telescopic plate 202c can squeeze the inclined surface on the top of the limiting pin 204c, thereby squeezing the limiting pin 204c into the limiting sleeve 204a. When the limiting groove U moves to the top of the limiting pin 204c, under the action of the reset elastic force of the fourth spring 204b, the limiting pin 204c can be inserted into the limiting groove U, thereby fixing the position of the telescopic plate 202c. At this time, even if the handle 202d is released, the telescopic plate 202c will not pop out of the limiting shell 201d.

[0048] Specifically, the limiting member 204 also includes a through hole 204d, a piston 204e, a fixed sleeve 204f and a support rod 204g. The through hole 204d is opened in the limiting sleeve 204a, the piston 204e slides in the limiting sleeve 204a, the fixed sleeve 204f is fixed to the bottom of the piston 204e, and the support rod 204g is fixed to the bottom of the fixed sleeve 204f.

[0049] When the limit pin 204c is squeezed into the limit sleeve 204a, the air in the limit sleeve 204a moves downward through the through hole 204d, and the other end of the support rod 204g is fixed to the inner bottom wall of the lower mold 103a. When the upper mold 103b squeezes the limit shell 201d, the limit shell 201d drives the limit sleeve 204a to move downward. At this time, since the piston 204e is fixed in the lower mold 103a through the fixed sleeve 204f and the support rod 204g, as the limit sleeve 204a moves downward, the air inside the limit sleeve 204a is discharged through the piston 204e and the fixed sleeve 204f.

[0050] Specifically, the limiting member 204 also includes a blocking block 204h and a fifth spring 204i. A through groove V is provided on the piston 204e. The blocking block 204h is located on one side of the through groove V. The two ends of the fifth spring 204i are respectively fixed to one side of the blocking block 204h and the inner wall of the fixed sleeve 204f. An exhaust groove W is provided on the surface of the fixed sleeve 204f, and a return air hole X is provided on the blocking block 204h.

[0051] The blocking block 204h is used to block the through slot V. The fifth spring 204i is in a compressed state. The elastic force of the fifth spring 204i can make the blocking block 204h close to one side of the through slot V. When the air in the limiting sleeve 204a needs to enter the fixing sleeve 204f from the chamber where the limiting pin 204c is located, the blocking block 204h can be squeezed so that the blocking block 204h compresses the fifth spring 204i. When the air discharge stops, the position of the blocking block 204h is reset under the elastic force of the fifth spring 204i. When the upper mold 103b is away from the limiting shell 201d, the limiting shell 201d can be driven by the reset elastic force of the first spring 201b. The limit sleeve 204a rises, thereby causing the limit sleeve 204a to move upward. At this time, since part of the air in the limit sleeve 204a has been discharged, the limit sleeve 204a suddenly moves upward, and the air pressure inside it is much lower than the normal atmospheric pressure, so that the air pressure presses the limit pin 204c into the limit sleeve 204a, releasing the limit pin 204c from the telescopic plate 202c. At this time, the telescopic plate 202c can be reset under the reset tension of the second spring 202b, and the return air hole X can slowly allow the outside air to pass through the fixed sleeve 204f and flow into the limit sleeve 204a from the return air hole X. Under the reset elastic force of the fourth spring 204b, the limit pin 204c is slowly reset.

[0052] When in use, when a punching operation is performed on the workpiece 205 .

[0053] First, place the workpiece 205 on the top of the telescopic plate 202c, push the handle 202d, and drive the telescopic plate 202c to move, so that the telescopic plate 202c stretches the second spring 202b, so that the workpiece 205 on the top of the telescopic plate 202c is sent between the lower mold 103a and the upper mold 103b. In this process, the workpiece 205 can be moved to the specified stamping position through the joint action of the limit plate 203a, the limit bar 203b, the push block 203c and the extrusion block 203d. At the same time, in this process When the telescopic plate 202c moves into the limiting shell 201d, the end of the telescopic plate 202c can squeeze the inclined surface at the top of the limiting pin 204c, thereby squeezing the limiting pin 204c into the limiting sleeve 204a. When the limiting groove U moves to the top of the limiting pin 204c, under the action of the restoring elastic force of the fourth spring 204b, the limiting pin 204c can be inserted into the limiting groove U, thereby fixing the position of the telescopic plate 202c. At this time, even if the handle 202d is released, the telescopic plate 202c will not pop out of the limiting shell 201d.

[0054] Then the upper die 103b moves downward, and the upper die 103b squeezes the limiting shell 201d, and the limiting shell 201d drives the limiting sleeve 204a to move downward. At this time, since the piston 204e is fixed in the lower die 103a through the fixed sleeve 204f and the support rod 204g, as the limiting sleeve 204a moves downward, the air inside the limiting sleeve 204a is discharged through the piston 204e and the fixed sleeve 204f. At the same time, the upper die 103b and the lower die 103a cooperate to complete the stamping of the workpiece 205.

[0055] After the workpiece 205 is stamped, the upper die 103b rises. At this time, the upper die 103b is away from the limiting shell 201d. Under the action of the return elastic force of the first spring 201b, the limiting shell 201d can be driven to rise, so that the limiting sleeve 204a moves upward. At this time, since part of the air in the limiting sleeve 204a has been discharged, the limiting sleeve 204a suddenly moves upward, and the air pressure inside it is much lower than the normal atmospheric pressure, so that the air pressure presses the limiting pin 204c into the limiting sleeve 204a, releasing the limiting pin 204c. 4c limits the telescopic plate 202c. At this time, the telescopic plate 202c can be reset and moved under the reset pulling force of the second spring 202b, so as to take out the scraps left after stamping. At the same time, the return air hole X can slowly allow the outside air to pass through the fixing sleeve 204f and flow into the limit sleeve 204a from the return air hole X. Under the reset elastic force of the fourth spring 204b, the limit pin 204c is slowly reset, so that the limit pin 204c can fix the telescopic plate 202c again during the next stamping.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
