Description

Technical Field

[0001] This utility model relates to the field of punching technology, specifically to a punching and anti-jumping waste material equipment for hardware parts. Background Technology

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting, used for fixing things, processing things, or decoration.

[0003] Currently, during the punching of metal parts, the waste material generated, after entering the punching hole, can be lifted upwards with the punch due to vacuum or magnetic force, and then carried out. This waste material may fall onto the metal part or adhere to the punch. If it falls onto the metal part, additional cleaning is required, increasing labor intensity. If it adheres to the punch, it causes inconvenience for subsequent punching operations. Therefore, a waste material anti-jumping device for metal part punching has been invented.

[0010] Countersunk holes: Several countersunk holes are provided at the top outer side of the bearing plate;

[0011] Through holes: Several through holes are provided at the bottom outer side of the support plate.

[0012] As a preferred embodiment of the hardware punching anti-jump scrap device of this utility model, the mounting assembly further includes:

[0013] The first stud is fixedly installed in the inner cavity of the lower mold, and the top end of the first stud passes through the through hole and is located in the countersunk hole;

[0014] The second stud is fixedly installed on the top of the first stud, and the thread directions of the first stud and the second stud are set to be opposite.

[0015] As a preferred embodiment of the hardware punching anti-jump scrap device of this utility model, the mounting assembly further includes:

[0016] A first nut is threaded onto a first stud, and the top end of the first stud is located inside the cavity of the first nut.

[0017] The second nut is threaded onto the second stud.

[0018] In a preferred embodiment of the hardware punching anti-jump scrap device of this utility model, the countersunk hole and the through hole are connected, and the diameter of the countersunk hole is larger than the diameter of the through hole.

[0019] In a preferred embodiment of the hardware punching anti-jump scrap device of this utility model, the diameter of the first stud is greater than the diameter of the second stud, and the diameter of the first nut is greater than the diameter of the first nut.

[0020] In a preferred embodiment of the hardware punching anti-jump scrap device of this utility model, the bottom of the first nut is in contact with the bottom surface of the countersunk hole, and the top of the first nut is in contact with the bottom of the second nut.

[0021] Compared with existing technologies:

[0022] By setting an inclined groove in the punch, the scrap generated during punching of hardware parts can be slightly rotated in the punch, so as to separate the scrap from the punch. This prevents the scrap from rising with the punch, which not only reduces the labor intensity of the workers to a certain extent, but also avoids affecting the next punching.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This utility model provides a device for preventing scrap from jumping out during punching of hardware parts. Please refer to [link / reference]. Figures 1-6 It includes a support plate 10 and a lower mold 30. The support plate 10 has punched holes, including an upper hole 20 and a lower hole 22. The top of the support plate 10 has an upper hole 20 and the bottom of the support plate 10 has a lower hole 22. The inner surface of the upper hole 20 has several oblique grooves 21 at equal intervals. The upper hole 20 and the lower hole 22 are connected, and the diameter of the upper hole 20 is smaller than the diameter of the lower hole 22.

[0032] It also includes: a mounting assembly for mounting the support plate 10 on the lower die 30, and the mounting assembly is located between the support plate 10 and the lower die 30; wherein, a blanking hole is provided on the lower die 30 located directly below the punching hole.

[0033] The mounting components include: countersunk hole 40, through hole 41, first stud 42, second stud 43, first nut 44, and second nut 45;

[0034] The outer top of the support plate 10 has several countersunk holes 40, and the outer bottom of the support plate 10 has several through holes 41. Several first studs 42 are fixedly installed in the inner cavity of the lower mold 30, and the top of the first stud 42 passes through the through hole 41 and is located in the countersunk hole 40. The second stud 43 is fixedly installed on the top of the first stud 42, and the thread directions of the first stud 42 and the second stud 43 are set to be opposite.
