Description

Technical Field

[0001] This invention relates to the field of progressive die equipment technology, and more particularly to a dynamic monitoring progressive die feeding direction locking mechanism. Background Technology

[0002] A progressive die is a type of continuous stamping die that passes a sheet metal through multiple stations in a stamping sequence, completing one process at a single station.

[0003] Existing mold feeding mechanisms lack an effective anti-backflow mechanism during the feeding process. Because progressive dies are fully automated production molds, the feeding process may be affected by human error or abnormalities, causing the feeder to run in the opposite direction, resulting in incorrect feeding and reverse material conveying, which affects the processing of subsequent mold equipment. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a dynamic monitoring progressive die feeding direction locking mechanism to solve the problem of lacking an effective anti-backflow mechanism to prevent workpiece reverse conveying.

[0005] To achieve the above objectives, the present invention provides a dynamic monitoring progressive die feeding direction locking mechanism, comprising a fixed block and a shim arranged sequentially on one side of the feeder, a sliding block slidably disposed on the fixed block, and a spring shim disposed between the sliding block and the fixed block, and an electromagnetic induction sensor installed on the corresponding sliding block.

[0006] A further improvement is that the end of the sliding block furthest from the electromagnetic induction sensor is a right-angled trapezoidal structure.

[0007] A further improvement is that screw holes are provided at both ends of the fixing block and the gasket, and the fixing block and the gasket are fixed to the feeder by bolts passing through the screw holes.

[0008] A further improvement is that a positioning groove is provided on the lower side of the fixing block, and a positioning key is provided in the positioning groove. The positioning key is installed on the feeder by screws.

[0009] A further improvement is that the fixed block has an installation groove, and the sliding block is slidably installed in the installation groove.

[0010] A further improvement is that the mounting groove is provided with a protrusion, and the sliding block is provided with a sliding groove, with the protrusion slidably disposed in the sliding groove.

[0011] A further improvement is that a mounting hole is provided on one side of the protrusion, one end of the spring is connected to the mounting hole, and the other end of the spring extends out of the mounting hole and is connected to the inner wall of the sliding groove.

[0012] The beneficial effects of this invention are as follows: By setting a sliding block with a right-angled trapezoidal structure at its end, the material contacts the inclined side and right-angled side of the sliding block end respectively during the forward and reverse conveying of the blank. The material pushes the sliding block and contacts the electromagnetic induction sensor, controlling the feeder to continue feeding and stop feeding in the opposite direction. This allows for dynamic monitoring of material conveying, effectively preventing reverse operation of the feeder due to human error or abnormality. The feeding direction is locked to ensure that the mold can only be fed in the set feeding direction during production, thus protecting the mold's safety. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] like Figure 1-4 As shown, this embodiment provides a dynamic monitoring progressive die feeding direction locking mechanism, including a fixing block 1 and a shim 2 arranged sequentially on one side of the feeder. Both ends of the fixing block 1 and the shim 2 are provided with screw holes 5. The fixing block 1 and the shim 2 are fixed to the feeder by bolts passing through the screw holes 5.

[0019] The fixed block 1 has a positioning groove 6 on its lower side, and a positioning key 7 is provided in the positioning groove 6. The positioning key 7 is engaged in the positioning groove 6 and is installed on the feeder by screws. The fixed block 1 is positioned by the positioning key 7.

[0020] A sliding block 3 is slidably mounted on the fixed block 1. The fixed block 1 has an installation groove 8. The sliding block 3 is slidably mounted in the installation groove 8. The installation groove 8 has a protrusion 9. The protrusion 9 and the fixed block 1 are integrally structured. The sliding block 3 has a sliding groove 10. The protrusion 9 is slidably mounted in the sliding groove 10. The protrusion 9 limits the sliding of the sliding block 3. A spring 12 is provided between the sliding block 3 and the fixed block 1. An installation hole 11 is provided on one side of the protrusion 9. One end of the spring 12 is connected to the installation hole 11. The other end of the spring 12 extends out of the installation hole 11 and is connected to the inner wall of the sliding groove 10. The spring 12 pushes the sliding block 3 to slide out from the installation groove 8. The sliding block 3 blocks the conveyed blank material.

[0021] An electromagnetic induction sensor 4 is installed on the gasket 2 corresponding to the sliding block 3. The end of the sliding block 3 away from the electromagnetic induction sensor 4 is a right-angled trapezoidal structure. When the blank is conveyed in a specified direction, it contacts the inclined side of the end of the sliding block 3, pushing the sliding block 3 to slide into the mounting groove 8. The end of the sliding block 3 close to the electromagnetic induction sensor 4 contacts the probe of the electromagnetic induction sensor 4. The electromagnetic induction sensor 4 sends a contact signal to the feeder, and the feeder continues to feed the blank. Conversely, if the blank contacts the right-angled side of the end of the sliding block 3, the sliding block 3 cannot slide and contact the electromagnetic induction sensor 4. The feeder will not receive a signal and will not work.

[0022] During processing, the blank is fed by a feeder. When the blank is conveyed in the forward direction, it contacts the inclined edge of the end of the sliding block 3, thereby pushing the sliding block 3 to retract and slide inward. The other end of the sliding block 3 contacts the electromagnetic induction sensor 4, which sends a signal, and the feeder continues to convey the blank. Conversely, when the blank is conveyed in the reverse direction, it contacts the right-angled edge of the sliding block 3. The blank cannot push the sliding block 3 to slide and contact the electromagnetic induction sensor 4, and the feeder stops conveying because it does not receive a signal.

[0023] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
