Description

Technical Field

[0001] This utility model relates to the field of blanking processing technology, and more specifically, to a multi-station feeding mechanism for blanking processing. Background Technology

[0002] In the field of blanking, the feeding mechanism is a crucial bridge connecting raw materials and blanking equipment, and its performance directly affects production efficiency and product quality. Traditional blanking feeding mechanisms are mostly fixed or large-scale automated equipment. While they can meet the needs of large-scale production, their flexibility and portability are insufficient for small-batch, multi-variety, or flexible on-site operation scenarios.

[0003] Especially in situations where manual operation is required, such as small workshops, on-site maintenance, or teaching demonstrations, traditional large-scale feeding mechanisms not only occupy a lot of space but are also complex to operate, making them difficult to adapt to these specific needs.

[0004] Existing handheld feeding devices also have certain problems in terms of feeding accuracy and stability. Due to design limitations, these devices are prone to deviations during the feeding process, resulting in unstable quality in the punching process. Utility Model Content

[0009] The push arm includes a first short rod and a first locking rod. The first short rod is rotatably disposed within the first arm locking plate. The first locking rod is connected to the first short rod through two parallel first connecting rods. The first locking rod is matched with the positioning toothed plate.

[0010] It also includes a feeding and pulling mechanism, which is mounted on the support frame on the rear side of the press support table.

[0011] The feeding and pulling mechanism includes a pulling base plate and a pulling swing arm. The pulling base plate adopts a rectangular flat plate structure and a positioning pin is provided at the bottom of the pulling base plate. The pulling swing arm is hinged to the pulling base plate through a second swing arm clamping plate.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figures 1 to 6 As shown, a multi-station feeding mechanism for punching includes a support frame 1, a press support table 4, and a feeding and pushing mechanism 5. The support frame 1 is arranged on both sides of the press support table 4, and the horizontal height of the support frame 1 is the same as that of the press support table 4. A positioning toothed plate 2 is provided on the support frame 1, and rollers 3 are arranged on the support frame 1. The feeding and pushing mechanism 5 is located on the support frame 1 in front of the press support table 4 and is mounted on the rollers 3. When punching and drilling holes in a strip of steel, the steel plate is placed on the rollers 3 of the support frame 1 and pushed towards the press support table 4. The feeding and pushing mechanism 5 clamps and fixes the steel plate. Then, two workers stand symmetrically on both sides of the support frame 1, each holding one side of the feeding and pushing mechanism 5 to perform the feeding operation. The steel plate is delivered to the press support table 4, where the press performs the punching operation.

[0026] Preferably, the feeding and pushing mechanism 5 includes a pushing base plate 51, a clamping frame 52, and a pushing swing arm 54. The pushing base plate 51 is a rectangular flat plate. The clamping frame 52 is fixedly mounted on the pushing base plate 51. The clamping frame 52 has an internally threaded sleeve, and a clamping bolt 53 is threaded onto the internally threaded sleeve. The pushing swing arm 54 is hinged to the pushing base plate 51 through a first swing arm clamping plate 55. Workers on both sides hold the pushing swing arm 54 on both sides and push the processed steel plate by sliding it on the roller 3 through the pushing base plate 51.

[0027] Preferably, the push arm 54 includes a first short rod 56 and a first locking rod 58. The first short rod 56 is rotatably mounted inside the first arm locking plate 55. The first locking rod 58 is connected to the first short rod 56 via two parallel first connecting rods 57. The first locking rod 58 is matched with the positioning toothed plate 2. Workers on both sides hold the first locking rod 58 on either side. According to the punching rhythm of the press, the workers push the first locking rod 58 forward, locking it in the positioning toothed plate 2 to stably position the steel plate. After one punching cycle, the first locking rod 57 is lifted out of the positioning toothed plate 2 and pushed forward one tooth position. This operation is repeated.

[0028] Preferably, it also includes a feeding and pulling mechanism 6, which is mounted on the support frame 1 on the rear side of the press support table 4. When the front end of the steel plate being processed has passed the press, the feeding and pushing mechanism 5 is restricted in its use, but the feeding and pulling mechanism 6 can continue to be used to feed the steel plate.

[0029] Preferably, the feeding and pulling mechanism 6 includes a pulling base plate 61 and a pulling swing arm 63. The pulling base plate 61 adopts a rectangular flat plate structure, and a positioning pin 62 is provided at the bottom of the pulling base plate 61. The pulling swing arm 63 is hinged to the pulling base plate 61 through a second swing arm clamping plate 64. The positioning pin 62 is inserted into the punched opening position on the steel plate to connect the pulling base plate 61 to the processed steel plate. The operator drags and feeds the steel plate through the feeding and pulling mechanism 6 to complete the punching operation.

[0030] Preferably, the pull arm 63 includes a second short rod 65 and a second locking rod 67. The second short rod 65 is rotatably mounted in the second arm locking plate 64. The second locking rod 67 is connected to the second short rod 65 via two parallel second connecting rods 66. The second locking rod 67 is matched with the positioning toothed plate 2. Workers on both sides hold the second locking rod 67 on either side. According to the punching rhythm of the press, the workers push the second locking rod 67 forward, locking it in the positioning toothed plate 2 to stably position the steel plate. After one punching cycle, the second locking rod 67 is lifted out of the positioning toothed plate 2 and pushed forward one tooth position. This operation is repeated.

[0031] Preferably, the positioning toothed plates 2 are symmetrically arranged on both sides of the support frame 1.

[0032] The steel plate to be processed is placed at the starting position of the support frame 1 and clamped with clamping bolts 53. Two workers push the feed simultaneously from both sides, and combined with the punching frequency of the press, the punching operation on the steel plate is completed, ensuring the accuracy of the punching and the high efficiency of the operation. After the front end of the steel plate extends out of the press support table 4, if it is inconvenient to use the feeding and pushing mechanism 5, the feeding and pushing mechanism 5 is removed. The pulling base plate 61 of the feeding and pulling mechanism 6 is connected to the front end of the steel plate, at the position where the hole has been punched. Through the pulling of two workers, the steel plate is fed in an orderly manner until the punching operation is completed.

[0033] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
