Description

Technical Field

[0001] The utility model relates to the technical field of spring sheet bending and forming, in particular to a bending and forming device for spring sheet processing. Background Art

[0002] Shrapnel stamping and bending forming equipment is a type of stamping equipment. It uses molds and punching force to bend, stamp and other forming operations on metal shrapnel. This equipment is widely used in many fields such as metal product processing, automobile parts manufacturing, and home appliance manufacturing. Especially in metal forming processing that requires high precision and high efficiency, shrapnel stamping and bending forming equipment plays an important role.

[0003] The spring clip stamping and bending forming equipment is provided with a feeding structure for providing metal strips. In the existing technology, after the strips are consumed, the staff needs to stop the machine, disassemble and replace the barrel for winding the strips, and then connect the new strips to the stamping equipment. Stopping the machine to replace the strips will seriously affect production efficiency. On an automated production line, any form of shutdown will interrupt the production process, resulting in a decrease in the overall efficiency of the production line. Especially in the case of high-speed production, frequent shutdowns to replace strips will significantly reduce output and increase production costs. Utility Model Content

[0004] In order to overcome the above technical problems, the purpose of the present invention is to provide a bending forming device for processing spring pieces.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A bending and forming device for processing spring pieces, comprising:

[0007] Shrapnel stamping and shaping device;

[0008] A bracket is placed on one side of the spring sheet stamping and shaping device;

[0009] a fixing plate, fixed on the top end of the bracket;

[0010] A rotating rod, rotatably mounted on a side surface of the fixed plate;

[0011] A mounting plate fixed to an end of the rotating rod away from the fixed plate;

[0012] Two feeding rollers are rotatably mounted on both ends of the fixed plate;

[0013] The positioning structure is arranged on the fixing plate.

[0014] As a further solution of the present invention: the positioning structure includes:

[0015] A positioning plate is placed on one side of the fixing plate;

[0016] Two positioning rods are respectively fixed at two ends of the positioning plate;

[0017] Two openings are both provided on the fixing plate;

[0018] Two positioning holes are both provided on the mounting plate;

[0019] Connecting piece, the positioning plate and the fixing plate are connected via the connecting piece.

[0020] As a further solution of the present invention: the connecting piece includes:

[0021] An outer cylinder is fixed on the side of the positioning plate;

[0022] an inner rod slidably disposed in the outer cylinder, one end of the inner rod extending to the outside of the outer cylinder and connected to the fixing plate;

[0023] A spring has one end connected to the outer cylinder and the other end connected to the inner rod.

[0024] As a further solution of the present invention: the inner surface of the outer cylinder and the outer surface of the inner rod are in contact with each other.

[0026] As a further solution of the present invention: a handle is installed on the positioning plate.

[0027] Beneficial effects of the utility model:

[0028] By designing a double feeding roller and a rotatable mounting plate, the alternating feeding of the feeding rollers is realized. In the initial state, one feeding roller is responsible for feeding. When the material belt is consumed, the staff does not need to stop the machine to replace it. Instead, they can simply rotate the mounting plate to rotate the other feeding roller to the feeding position and continue feeding. This alternating feeding method greatly improves work efficiency and reduces the time required to stop the machine to replace the material belt. At the same time, the equipment is also designed with a fixing structure of the positioning rod and the positioning port, as well as a reset mechanism of the positioning plate and the spring. When replacing the feeding roller, the staff only needs to pull the positioning plate to move the positioning rod out of the positioning port, release the restriction on the mounting plate, and then rotate the mounting plate to rotate the other feeding roller to the feeding position. After releasing the positioning plate, the positioning plate will reset under the action of the spring, and the positioning rod will be reinserted into the positioning port to position the angle of the mounting plate to ensure the stability of the feeding roller during the feeding process. This design not only simplifies the operation process of replacing the feeding roller, reduces the difficulty of operation, but also improves the stability and safety of feeding.

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figs. 1-3 As shown, a bending forming equipment for shrapnel processing includes a shrapnel stamping and shaping device 1; a bracket 2, which is placed on one side of the shrapnel stamping and shaping device 1; a fixed plate 3, which is fixed to the top of the bracket 2; a rotating rod 4, which is rotatably mounted on the side of the fixed plate 3; a mounting plate 5, which is fixed to the end of the rotating rod 4 away from the fixed plate 3; two feeding rollers 6, which are rotatably mounted on both ends of the fixed plate 3, and when the material strip on one of the feeding rollers 6 is consumed, the staff can rotate the other feeding roller 6 to a position close to the shrapnel stamping and shaping device 1, and use the material strip on the feeding roller 6 to feed the shrapnel stamping and shaping device 1. Therefore, the staff can alternately use the two feeding rollers 6 to feed the shrapnel stamping and shaping device 1, and when one of the feeding rollers 6 is feeding, the staff can replace the other feeding roller 6;

[0036] The bending forming equipment for shrapnel processing also includes a positioning structure, which is arranged on the fixed plate 3. The positioning structure includes: a positioning plate 71, which is placed on one side of the fixed plate 3, and a handle is installed on the positioning plate 71; two positioning rods 72 are respectively fixed at both ends of the positioning plate 71; two openings 73 are both opened on the fixed plate 3; two positioning holes 74 are both opened on the mounting plate 5, and the outer surface of the positioning rod 72 fits with the inner surface of the positioning hole 74. When replacing the feed roller 6, the staff first pulls the positioning plate 71 to make the positioning plate 71 drive the two positioning rods 72 to move until the two positioning rods 72 move out of the two positioning holes 74. Without the restriction of the two positioning rods 72, the mounting plate 5 can rotate freely. Then the staff rotates the mounting plate 5 to rotate it 180° until the other feed roller 6 rotates to a position close to the shrapnel punching fixed position. When the locking cam 72 is in the closed position, the locking cam 72 is in the closed position, and the cam 72 is in the closed position, so that the cam 72 is in the closed position and the cam 72 is in the closed position.

[0037] The working principle of this utility model:

[0038] When the bending and forming equipment for processing shrapnel proposed by the present invention is in use, in the initial state, the feeding roller 6 close to the shrapnel stamping and shaping device 1 feeds the shrapnel stamping and shaping device 1. During the stamping process of the shrapnel, the two positioning rods 72 pass through the two openings 73 respectively and are inserted into the two positioning holes 74. At this time, the two positioning rods 72 and the two positioning holes 74 fix the mounting plate 5, and the positions of the two feeding rollers 6 are also fixed. When the material strip on one of the feeding rollers 6 is consumed, the staff can rotate the mounting plate 5 to rotate the other feeding roller 6 to a position close to the shrapnel stamping and shaping device 1, and use the material strip on the feeding roller 6 to feed the shrapnel stamping and shaping device 1. Therefore, the staff can alternately use the two feeding rollers 6 to feed the shrapnel stamping and shaping device 1. When one of the feeding rollers 6 is feeding, the staff can replace the other feeding roller 6. There is no need to spend a lot of time to replace the feeding roller 6, thereby ensuring the working efficiency of the device.

[0039] When the feeding roller 6 is replaced, the worker first pulls the positioning plate 71, and the positioning plate 71 drives the two positioning rods 72 to move until the two positioning rods 72 move out of the two positioning ports 74, and the installation plate 5 can be freely rotated without the limitation of the two positioning rods 72, then the worker rotates the installation plate 5, and the installation plate 5 is rotated by 180° until the other feeding roller 6 is rotated to the position close to the bullet stamping and shaping device 1, at this time, the worker releases the positioning plate 71, and the positioning plate 71 is reset under the action of the spring 83, so that the two positioning rods 72 are respectively inserted into the two positioning ports 74, at this time, the two positioning rods 72 and the two positioning ports 74 position the installation plate 5, and the stability of the feeding roller 6 during feeding is guaranteed, in addition, the outer cylinder 81 and the inner rod 82 limit and guide the movement of the positioning plate 71 during the movement of the positioning plate 71.

[0040] The above describes one embodiment of the utility model in detail, but the content described can only be the preferred embodiment of the utility model, and cannot be considered as limiting the implementation scope of the utility model. Any equivalent change and improvement within the scope of the utility model application should still belong to the patent coverage of the utility model.
