Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and in particular to a stamping die for metal parts. Background Art

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts. However, in the production process, due to the structural characteristics of the products to be stamped, there are situations where continuous stamping operations cannot be carried out, and only individual stamping operations can be performed. However, in order to prevent the workpieces 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 workpieces. However, due to the influence of the movement range of the equipment itself, when manually supporting the workpieces, the stamping die is likely to cause harm to the workers.

[0026] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific implementation modes of the present invention in conjunction with the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation mode of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments. Embodiment 1

[0029] Referring to Figures 1 to 7 , which is the first embodiment of the present invention. This embodiment provides a stamping die for metal parts. The stamping die for metal parts includes a main body assembly 100 and a feeding assembly 200. Through the cooperation of the two, the workpiece 205 can be sent to the designated stamping position and fixed, so that it is not necessary for workers to hold the workpiece 205, thereby avoiding damage to the workers. After stamping, the excess scrap can be automatically removed from the stamping die.

[0030] Specifically, the main body assembly 100 includes a support table 101, positioning columns 102, and a stamping part 103. The positioning columns 102 are fixed on the top of the support table 101, and the stamping part 103 is arranged on the surface of the positioning columns 102.

[0031] The support table 101 is used to fixedly support the positioning columns 102. The positioning columns 102 are used to limit the position of the stamping part 103. The stamping part 103 is used to stamp the workpiece to obtain the required metal parts.

[0032] The feeding assembly 200 is arranged on the stamping part 103 and includes a lifting member 201, a telescopic member 202, a positioning member 203, a limiting member 204, and a workpiece 205. The lifting member 201 is arranged inside the stamping part 103. The telescopic member 202 is located inside the lifting member 201. The positioning member 203 is arranged inside the telescopic member 202. The limiting member 204 is located inside the stamping part 103.

[0033] The lifting member 201 is used to support the feeding assembly 200, and the setting of the lifting member 201 enables the scrap and the stamped metal parts to be separated after the workpiece 205 is stamped by the stamping part 103. The telescopic member 202 is used to move the workpiece 205 to the designated position to be stamped, and at the same time, the scrap after stamping can be moved out. The positioning member 203 is used to fix the position of the workpiece 205, so as to prevent the workpiece 205 from shifting during the stamping process. The limiting member 204 is used to limit the position of the telescopic member 202. When the stamping is completed, the limiting member 204 can release the limit on the telescopic member 202, so that the telescopic member 202 drives the scrap to move out of the stamping part 103.

[0034] Specifically, the stamping part 103 includes a lower die 103a and an upper die 103b. The lower die 103a is fixed to the top of the support table 101, and the upper die 103b slides on the surface of the positioning column 102.

[0035] The lower die 103a is used to support the feeding assembly 200, and the upper die 103b can cooperate with the lower die 103a to stamp out the required metal parts from the workpiece 205.

[0036] Specifically, the lifting member 201 includes a lifting sleeve 201a and a first spring 201b. The lifting sleeve 201a slides in the lower die 103a, and both ends of the first spring 201b are fixed to the inner wall of the lifting sleeve 201a and the inner wall of the lower die 103a respectively.

[0037] The first spring 201b is in a compressed state. Through the restoring elastic force of the first spring 201b, the lifting sleeve 201a can be pushed, so that the lifting member 201 can move up and down in the lower die 103a.

[0038] Specifically, the lifting member 201 further includes a support column 201c and a limit shell 201d. Both ends of the support column 201c are fixed to the top of the lifting sleeve 201a and the bottom of the limit shell 201d respectively, and the limit shell 201d slides in the lower die 103a.

[0039] When the upper die 103b squeezes the lower die 103a, the upper die 103b will first squeeze the limit shell 201d, so that the limit 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 stamp 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 limit shell 201d can be driven to move upward. Embodiment 2

[0040] Refer to 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.

[0041] 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 limit shell 201d. 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 within the limit shell 201d, and the handle 202d is fixed to the end of the telescopic plate 202c.

[0042] The support block 202a is used to support the second spring 202b. The second spring 202b is in a normal state. The telescopic plate 202c is used to carry the workpiece 205. By pushing the handle 202d, the telescopic plate 202c can be driven to move, so that the telescopic plate 202c stretches the second spring 202b, thereby sending the workpiece 205 on the top of the telescopic plate 202c between the lower die 103a and the upper die 103b.

[0043] Specifically, the positioning member 203 includes a limit plate 203a and a limit strip 203b. The limit plate 203a is fixed to the top of the limit shell 201d by bolts. The limit strip 203b is fixed to the end of the limit plate 203a, and the limit strip 203b is located on the surface of the telescopic plate 202c.

[0044] The limit 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 limit strip 203b is used to limit the workpiece 205 so that the workpiece 205 moves to the bottom of the limit plate 203a. When the workpiece 205 moves to the bottom of the limit plate 203a, both sides of the workpiece 205 will be squeezed by one side of the limit shell 201d, thereby limiting the position of the workpiece 205.

[0045] Specifically, the positioning member 203 further 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 within the telescopic plate 202c. The positioning rod 203e is fixed to one side of the extrusion block 203d. 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.

[0046] The pushing block 203c is used to push the workpiece 205 to prevent the workpiece 205 from slipping on the telescopic plate 202c, so that it cannot move to the bottom of the limiting plate 203a. When the telescopic plate 202c moves into the limiting housing 201d, as the telescopic plate 202c moves, the positioning rod 203e will squeeze the inner wall of the limiting housing 201d, causing the positioning rod 203e to squeeze the third spring 203f, thereby compressing the third spring 203f. At this time, the positioning rod 203e drives the extrusion block 203d to move towards 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 combined limitation of the extrusion block 203d and the pushing block 203c, the workpiece 205 is fixed at the specified stamping position. Embodiment 3

[0047] Refer to Figures 2 to 5 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0048] 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 inside the limiting housing 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 inside the limiting sleeve 204a. A limiting groove U is formed on the telescopic plate 202c, and the limiting pin 204c can be inserted into the limiting groove U.

[0049] The limiting sleeve 204a is used to limit the limiting pin 204c. The fourth spring 204b is in a compressed state. The top of the limiting pin 204c is provided with an inclined surface. When the telescopic plate 202c moves into the limiting housing 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 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, when the handle 202d is released, the telescopic plate 202c will not pop out of the limiting housing 201d.

[0050] Specifically, the limiting member 204 further includes a through hole 204d, a piston 204e, a fixed sleeve 204f, and a support rod 204g. The through hole 204d is formed in the limiting sleeve 204a. The piston 204e slides inside the limiting sleeve 204a. The fixed sleeve 204f is fixed to the bottom of the piston 204e. The support rod 204g is fixed to the bottom of the fixed sleeve 204f.

[0051] 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. The other end of the support rod 204g is fixed to the inner bottom wall of the lower die 103a. When the upper die 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 to the inner part of the lower die 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.

[0052] Specifically, the limiting member 204 further includes a blocking block 204h and a fifth spring 204i. A through groove V is formed on the piston 204e. The blocking block 204h is located on one side of the through groove V. 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 formed on the surface of the fixed sleeve 204f, and a return air hole X is formed on the blocking block 204h.

[0053] The blocking block 204h is used to block the through groove V. The fifth spring 204i is in a compressed state. Due to the elastic force of the fifth spring 204i, the blocking block 204h can be closely attached to one side of the through groove V. When the air in the limit sleeve 204a needs to enter the fixed sleeve 204f from the chamber where the limit 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, under the elastic force of the fifth spring 204i, the position of the blocking block 204h is reset. When the upper die 103b moves away from the limit shell 201d, under the reset elastic force of the first spring 201b, the limit shell 201d can be driven to rise, so that the limit sleeve 204a moves upward. At this time, since a part of the air in the limit sleeve 204a has been discharged, when the limit sleeve 204a suddenly moves upward, the air pressure inside it is much smaller than the normal atmospheric pressure, so that the air pressure presses the limit pin 204c into the limit sleeve 204a, releasing the limit of the limit pin 204c on the telescopic plate 202c. At this time, the telescopic plate 202c can move in a reset manner under the reset pulling force of the second spring 202b. At the same time, the return air hole X can slowly allow the outside air to flow through the fixed sleeve 204f and 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.

[0054] During use, when stamping the workpiece 205.

[0055] First, place the workpiece 205 on the top of the telescopic plate 202c. Push the handle 202d to drive the telescopic plate 202c to move, so that the telescopic plate 202c stretches the second spring 202b, and thus the workpiece 205 on the top of the telescopic plate 202c is fed between the lower die 103a and the upper die 103b. During this process, through the combined action of the limit plate 203a, the limit strip 203b, the push block 203c and the extrusion block 203d, the workpiece 205 can be moved to the specified stamping position. At the same time, during this process, when the telescopic plate 202c moves into the limit shell 201d, the end of the telescopic plate 202c can squeeze the inclined surface at the top of the limit pin 204c, so as to squeeze the limit pin 204c into the limit sleeve 204a. When the limit groove U moves to the top of the limit pin 204c, under the reset elastic force of the fourth spring 204b, the limit pin 204c can be inserted into the limit groove U, so as to fix the position of the telescopic plate 202c. At this time, release the handle 202d, and the telescopic plate 202c will not pop out of the limit shell 201d.

[0056] Then make the upper die 103b move downward. The upper die 103b squeezes the limit shell 201d, and the limit shell 201d drives the limit 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 limit sleeve 204a moves downward, the air inside the limit sleeve 204a is discharged through the piston 204e and the fixed sleeve 204f. At the same time, with the cooperation of the upper die 103b and the lower die 103a, the stamping of the workpiece 205 is completed.

[0057] After the stamping of the workpiece 205 is completed, the upper die 103b rises. At this time, the upper die 103b moves away from the limit shell 201d. Under the reset elastic force of the first spring 201b, it can drive the limit shell 201d to rise, so that the limit sleeve 204a moves upward. At this time, since a part of the air inside the limit sleeve 204a has been discharged, when the limit sleeve 204a suddenly moves upward, the air pressure inside it is much less than the normal atmospheric pressure, so that the air pressure presses the limit pin 204c into the limit sleeve 204a, releasing the limit of the limit pin 204c on the telescopic plate 202c. At this time, the telescopic plate 202c can move in a reset manner under the reset pulling force of the second spring 202b, so as to take out the scraps left after stamping together. At the same time, the air return hole X can slowly allow the outside air to pass through the fixed sleeve 204f and flow into the limit sleeve 204a from the air return 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.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
