Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting equipment, in particular to an opening and closing mechanism of a controllable eye mold. Background Art

[0002] In the field of wire cutting equipment, the eye mold is a key positioning and processing component. The accuracy and stability of its opening and closing control directly affect the processing accuracy and efficiency. With the growing demand for high-precision and high-efficiency processing in the manufacturing industry, the traditional eye mold opening and closing mechanism can no longer meet the needs of modern wire cutting equipment.

[0003] First of all, traditional eye mold opening and closing mechanisms mostly use mechanical drive, and their opening and closing speed, accuracy and stability are limited by the mechanical structure itself, which makes it difficult to meet the requirements of high-precision wire cutting equipment for eye mold opening and closing accuracy.

[0004] Secondly, during the wire cutting process, a large amount of heat and debris will be generated due to the high-frequency discharge between the electrode wire and the workpiece. If the opening and closing mechanism of the eye mold cannot effectively dissipate heat and remove debris, it will cause the eye mold to wear more, reduce processing accuracy, and even cause equipment failure.

[0005] In addition, as wire cutting equipment develops towards intelligence and automation, higher requirements are placed on the control accuracy, response speed and reliability of the eye mold opening and closing mechanism. Traditional mechanical drive methods can no longer meet these requirements, and new drive and control technologies need to be sought. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] like Figure 1-10As shown, a controllable opening and closing mechanism of an eye mold comprises an L-shaped seat 1, a placement plate 2, a driving structure 3 and an eye mold 4;

[0055] The driving structure 3 and the placement plate 2 are installed on the L-shaped seat 1, and part of the plate surface of the placement plate 2 is suspended on the L-shaped seat 1. A mounting hole 20 is opened on the suspended plate surface of the placement plate 2, and the eye mold 4 is installed above the mounting hole 20;

[0056] The eye mold 4 includes a first eye mold seat group 41, the first eye mold seat group 41 includes two symmetrically arranged first eye mold seats 411, the two first eye mold seats 411 are provided with a first threading eye mold core 412, and the middle of the first threading eye mold core 412 is provided with a first threading eye mold half hole 413;

[0057] The sides of the two first eye mold seats 411 are both provided with a connecting portion 414, and the connecting portion 414 is used to connect the driving structure 3, and the driving structure 3 is used to drive the two first eye mold seats 411 to move away from or towards each other;

[0058] When the two first eye mold seats 411 are close to each other, the two first threading eye mold cores 412 form a first direction gap, and the two first threading eye mold half holes 413 form a first threading eye mold hole 410.

[0059] The opening and closing mechanism of the controllable eye mold 4 is mainly composed of four parts: an L-shaped seat 1, a placement plate 2, a driving structure 3 and an eye mold 4. The L-shaped seat 1 firmly supports the placement plate 2 and the driving structure. One end of the placement plate 2 is fixed on the L-shaped seat 1, and the other end is suspended to form a suspended board surface. On the suspended board surface, a mounting hole 20 is designed for mounting the eye mold 4. The eye mold 4 is composed of a first eye mold seat group 41, which includes two symmetrically arranged first eye mold seats 411. The first wire threading eye mold core 412 is embedded in the two first eye mold seats 411, and the first wire threading eye mold half hole 413 is opened in the middle of the first wire threading eye mold core 412. The sides of the two first eye mold seats 411 are provided with connecting parts 414, which are connected to the driving structure 3. Through the action of the driving structure 3, the two first eye mold seats 411 can be accurately controlled to move away from or close to each other.

[0060] When the driving structure 3 is started, power is transmitted through the connecting part 414 to drive the two first eye mold seats 411 to move relative to each other. When the two first eye mold seats 411 are close to each other, the first threading eye mold half holes 413 between them will align with each other to form a complete first threading eye mold hole 410 and a first direction gap. This complete first threading eye mold hole 410 can be used for threading operation.

[0061] To further illustrate, the eye mold 4 further includes a second eye mold seat group 42 movably disposed in the first eye mold seat group 41;

[0062] The second eye mold seat group 42 is arranged on one side of the first eye mold seat group 41 in the vertical direction;

[0063] The second eye mold seat group 42 includes two symmetrically arranged second eye mold seats 421, the two second eye mold seats 421 are provided with a second threading eye mold core 422, and the middle of the second threading eye mold core 422 is provided with a second threading eye mold half hole 423;

[0064] A linkage member 5 is disposed between the first eye mold seat group 41 and the second eye mold seat group 42. When the two first eye mold seats 411 move closer to or farther from each other, the linkage member 5 drives the two second eye mold seats 421 to move closer to or farther from each other.

[0065] When the two second eyelet mold seats 421 are close to each other, the two second threading eyelet mold cores 422 form a second direction gap, and the two second threading eyelet mold half holes 423 form a second threading eyelet mold hole 420, and the second threading eyelet mold hole 420 is arranged corresponding to the first threading eyelet mold hole 410;

[0066] The first direction gap and the second direction gap are not on the same straight line in the vertical direction.

[0067] In order to ensure the stability and accuracy of the entire eye mold 4, a linkage mechanism is designed between the first eye mold seat group 41 and the second eye mold seat group 42 through the linkage member 5. When the two first eye mold seats 411 approach each other, the two second eye mold seats 421 also approach each other accordingly. This linkage design ensures that when the first direction gap and the first threading eye mold hole change, the second direction gap and the second threading eye mold hole also change gradually.

[0068] When the two first eye mold seats 411 are merged, a first direction gap is formed between them. The first direction gap is located between the two first eye mold seats 411, and is used to limit the movement of the metal wire in other directions. At the same time, the two first wire threading eye mold half holes 413 are merged into a complete first wire threading eye mold hole for the wire threading operation.

[0069] When the two second eye mold seats 421 are combined, a second direction gap is formed between them, which is perpendicular to the first direction gap and is used to limit the movement of the metal wire in the first direction. At the same time, the two second wire threading eye mold half holes 423 are combined into a complete second wire threading eye mold hole, which is set corresponding to the first wire threading eye mold hole for the wire threading operation.

[0070] The utility model drives the linkage mechanism of the two first eye die seats 411 by adjusting the two first eye die seats 411. When the metal wire needs to be threaded, the two first eye die seats 411 are moved away from each other by the driving structure 3, and the two second eye die seats 421 are driven to move away from each other. At this time, the aperture of the first threading eye die hole and the aperture of the second threading eye die hole are both enlarged, which is convenient for the threading operation of the metal wire. After the threading operation of the metal wire is completed, the two first eye die seats 411 are brought closer to each other, and the two second eye die seats 421 are driven to be closer to each other. At this time, the aperture of the first threading eye die hole and the aperture of the second threading eye die hole are both reduced and the metal wire plays a role in guiding and stabilizing the wire. The first direction gap and the second direction gap set in an offset manner can prevent the metal wire from moving in the radial direction, thereby ensuring the stability and accuracy of the metal wire during the processing. In addition, the linkage mechanism between the first eye die seat group 41 and the second eye die seat group 42 can also improve the convenience and efficiency of operation, and reduce the time and error of manual adjustment.

[0071] In summary, the beneficial effects of the eye mold 4 of the utility model are as follows:

[0072] 1 Corresponding setting: The first wire threading eyelet die hole and the second wire threading eyelet die hole are set correspondingly, which means that their positions and sizes are matched, which can ensure that the metal wire can be smoothly threaded in these two holes.

[0073] 2. Offset setting: The first direction gap and the second direction gap are offset, which can limit the movement of the metal wire in all directions on the first eye die seat group 41 and the second eye die seat group 42, thereby ensuring the cutting accuracy and stability.

[0074] 3 Linkage setting: The synchronous adjustment of the first eye die set 41 and the second eye die set 42 is realized, which improves the precision and efficiency of the wire cutting process. At the same time, due to the precise adjustment of the first wire threading eye die hole, the second wire threading eye die hole, the first direction gap and the second direction gap, the processing error caused by the deviation of the metal wire is also reduced.

[0075] To further explain, at least two installation grooves 424 are arranged on the opposite side of the two second eye mold seats 421, and the two installation grooves 424 are respectively arranged at the two ends of the second eye mold seat 421, and the linkage member 5 is a reset spring, and the two installation grooves 424 are respectively provided with the reset springs, and under the elastic force of the reset springs, the two second eye mold seats 421 have a tendency to move away from each other.

[0076] Specifically, at least two mounting grooves 424 are carefully designed on the opposite sides of the second eye mold seat 421, and the two mounting grooves 424 are symmetrically arranged at the two ends of the second eye mold seat 421 to achieve balanced force distribution. The reset spring as the linkage member 5 is cleverly embedded in each mounting groove 424, thereby constructing an efficient elastic linkage system. Under the natural elastic force of the reset spring, the two second eye mold seats 421 always maintain a tendency to separate from each other, ensuring the stability of the structure and the flexibility of operation. Once the driving structure 3 acts as an external force on the two first eye mold seats 411, and at the same time makes the two first eye mold seats 411 and the two second eye mold seats 421 approach each other, the reset spring will be temporarily compressed to adapt to the change of this force.

[0077] To further illustrate, a triangular groove 415 is provided on one side of the first eye mold seat 411 facing the second eye mold seat 421. When the two first eye mold seats 411 are close to each other, the two triangular grooves 415 are close to each other and merge to form a diamond groove.

[0078] The two second eye mold seats 421 are respectively triangular pieces, and the two second eye mold seats 421 are close to each other and merged to form a diamond-shaped piece;

[0079] The two second eye mold seats 421 are embedded in the two triangular grooves 415 , and the side surfaces of the second eye mold seats 421 are in contact with the groove walls of the triangular grooves 415 .

[0080] Wedging and linkage design based on geometric shapes. First, as the two first eye mold seats 411 approach each other, their bottom triangular grooves 415 will gradually merge into a complete rhombus groove. At this time, due to the geometric characteristics of the rhombus groove, the two second eye mold seats 421 embedded therein will also move accordingly. Specifically, as the side length of the rhombus groove gradually shortens, the two second eye mold seats 421 will be squeezed by the rhombus groove, thereby moving along the diagonal direction of the rhombus groove to achieve a gradually approaching effect. This wedging and linkage mechanism ensures that the two second eye mold seats 421 can move synchronously when the first eye mold seat 411 approaches, achieving a precise linkage effect, and no additional mechanical connectors are required, reducing the possibility of wear and loosening, thereby enhancing durability.

[0081] To further illustrate, the groove edge of the triangular groove 415 is provided with a first half groove 416;

[0082] The edge of the second eye mold seat 421 is provided with a second half groove 425;

[0083] A guide through hole 417 is formed at a corner of the triangular groove 415 away from the first direction gap;

[0084] When the side surface of the second eye mold seat 421 fits with the groove wall of the triangular groove 415, the first half groove 416 and the second half groove 425 form a guide channel, and the guide through hole 417 is connected to the guide channel, and a roller is installed in the guide channel. The roller is installed in the guide channel through the guide through hole 417, and the roller is used for guiding.

[0085] Specifically, the combination of the first half groove 416 and the second half groove 425 makes the formation of the installation channel simple and intuitive. The needle roller is not shown in the drawings as a guide element. Through the connection between the guide through hole 417 and the installation channel, accurate control of the assembly process is achieved. When the two first eye mold seats 411 drive the two second eye mold seats 421 to move closer to or away from each other, the movement of the needle roller in the guide channel ensures the accuracy and stability of the assembly.

[0086] To further explain, the first wire threading die half hole 413 includes a first conical half hole 4131 and a first guide half hole 4132 which are connected in sequence, and the first guide half hole 4132 is arranged close to the second wire threading die hole 420.

[0087] To further explain, the cross-sectional shape of the second wire threading die half hole 423 includes a second conical half hole 4231 and a second guide half hole 4232 connected in sequence, and the second guide half hole 4232 is arranged close to the first wire threading die hole 410.

[0088] Specifically, the first wire threading die half hole 413 cleverly combines the first conical half hole 4131 and the first guide half hole 4132, wherein the first conical half hole 4131 is responsible for initially guiding the metal wire to enter, while the first guide half hole 4132 is arranged close to the second wire threading die hole 420, ensuring that the metal wire can smoothly transition to the next stage.

[0089] The second threading eyelet half hole 423 also adopts an innovative design, which is formed by sequentially connecting the second tapered half hole 4231 and the second guide half hole 4232. The second tapered half hole 4231 is used to further adjust and stabilize the traveling direction of the metal wire, while the second guide half hole 4232 is adjacent to the first guide half hole 4132 of the first threading eyelet hole 410, forming a continuous guide channel.

[0090] This design allows the metal wire to first enter from the first tapered half hole 4131 of the first wire threading eyelet die hole 410, and then smoothly transition to the second tapered half hole 4231 of the second wire threading eyelet die hole 420 after being precisely guided by the first guide half hole 4132, and finally complete the entire wire threading process in the second guide half hole 4232. During the entire process, the metal wire is continuously and stably guided, thereby significantly improving the efficiency and accuracy of wire threading.

[0091] Further explanation, it also includes a protective plate 6, a water spray nozzle 7 and a connecting seat 8;

[0092] The protective plate 6 covers the top of the L-shaped seat 1, and a through hole 60 is opened on the protective plate 6, and the through hole 60 is arranged corresponding to the mounting hole 20. The water nozzle 7 is installed in the through hole 60, and the water nozzle 7 is installed above the eye mold 4. The connecting seat 8 is installed above the water nozzle 7. The connecting seat 8 is used to connect to an external water diversion structure, and the water nozzle 7 is used to spray water to cool the metal wire.

[0093] When the metal wire needs to be processed through the eye mold 4, the driving structure 3 is first started to put the eye mold 4 in an open state. At this time, the operator can pass the metal wire through the eye mold 4. In the process of the metal wire passing through the eye mold 4, the temperature of the metal wire will rise due to friction and heat generated by processing. In order to maintain the performance and shape of the metal wire, the water nozzle 7 will be started, and water will be supplied to the water nozzle 7 through the water diversion structure connected to the connecting seat 8. Water is sprayed from the water nozzle 7 and directly acts on the metal wire to cool it. When the metal wire completely passes through the eye mold 4, the driving structure 3 is started again to close the eye mold 4, completing a processing process.

[0094] To further illustrate, the driving structure 3 includes a driving motor 31, a moving guide rail 32, two sliding blocks 33 and two symmetrically arranged connecting plates 34;

[0095] The driving motor 31 and the movable guide rail 32 are fixedly installed on the L-shaped seat 1, the two sliding blocks 33 are slidably installed on the movable guide rail 32, one end of the two connecting plates 34 are respectively fixedly connected to the two sliding blocks 33, and the other ends of the two connecting plates 34 are respectively detachably connected to the connecting parts 414 of the two first eye mold seats 411.

[0096] To further illustrate, the other end of the connecting plate 34 is provided with a void avoidance groove 341 and a void avoidance hole 342;

[0097] The connecting plate 34 is clamped on the connecting portion 414 through the air avoidance groove 341 , and the connecting plate 34 is fitted on the first eye mold seat 411 through the air avoidance hole 342 , and the upper end surface and the lower end surface of the first eye mold seat 411 are flush with the upper plate surface and the lower plate surface of the connecting plate 34 .

[0098] When the opening and closing of the eye mold 4 needs to be controlled, the driving motor 31 starts to work, driving the sliding block 33 assembly on the movable guide rail 32 to move. Since the sliding block 33 is fixedly connected to one end of the connecting plate 34, the connecting plate 34 will move accordingly. By adopting the driving mode of the driving motor 31 and the movable guide rail 32, the opening and closing action of the eye mold 4 can be accurately controlled and automatically operated, thereby improving production efficiency.

[0099] Due to the avoidance groove 341 and avoidance hole 342 provided on the connecting plate 34, the connecting plate 34 can be stably clamped on the connecting portion 414 of the first eye mold seat 411 and fit its surface. As the sliding block 33 moves, the connecting plate 34 drives the first eye mold seat 411 to open and close. The design of the avoidance groove 341 and avoidance hole 342 makes the connection between the connecting plate 34 and the first eye mold seat 411 tighter and more stable, ensuring the sealing and flatness of the eye mold 4 in the closed state, and improving the product quality.
