Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a slider control device capable of controlling the movement gap of a slider. Background Art

[0002] In the existing automobile covering parts, in order to achieve aesthetic assembly and rigid size control, some flanges with different lengths and directions need to be designed on the parts to restrict the rebound of the parts, especially some corner parts, which need to be realized by flanges in several directions. Under the current cost pressure, the number of mold sets is getting smaller and smaller, and the structure is getting more and more complicated. How to achieve multiple negative angle flanges in a limited space to ensure the quality of the flanges? At the same time, in the need of environmental green development, reducing the noise of stamping molds and increasing the service life of molds are also issues that need to be considered in structural design. This has led to more and more special non-standard inclined wedge mechanisms appearing in the mold, especially the side negative angle flanges. Non-standard reciprocating sliders need to be designed to ensure that the parts can be smoothly taken out and put in from the mold. Sometimes, when the process is limited and the space is tight, the design of non-standard reciprocating slider structures requires a very high level of technology. First of all, it is necessary to consider whether the movement direction of the slider, the stamping direction and the driving direction are consistent. If they are not consistent, how to overcome the force and movement of the mechanism during work? Whether it is good or not, in the actual manufacturing and production process, the unstable working state of the slider often leads to production suspension and even mold scrapping, which seriously affects and hinders production. Secondly, it is necessary to consider the gap distribution in different directions of the slider. The correct gap distribution can ensure that the slider moves and bears force well, especially when the movement and force directions are inconsistent. It is particularly necessary. The corresponding freedom constraint restrictions, support and guide distribution, etc. are also the guarantee of controlling the gap, which is the key factor in determining the normal production stability of the slider and the mold. Finally, the reciprocating slider stroke has a great influence on the placement of parts. If the stroke design is not large enough, the robot cannot normally place and take parts, resulting in the inability to produce the mold normally. If the slider stroke is increased, a larger stroke nitrogen cylinder needs to be selected. However, the stroke of each nitrogen cylinder cannot exceed 80% of the rated stroke. In particular, with the limitation of structural space, it is very critical to select a structure with constant force and double stroke to solve the problem of small space and stroke meeting requirements.

[0003] To sum up, it is particularly necessary to design a set of mold design ideas and methods with compact structure, correctly control the slider movement clearance, ensure the normal movement and operation of the slider, and reduce the wear of the slider. Summary of the invention

[0024] See also Figure 1-Figure 7It can be seen that the present invention provides a technical solution: a slider control device capable of controlling the movement gap of a slider, comprising: a driving slider 1 and a first roller wedge 3, a reciprocating slider body 2 is arranged on the outer side of the driving slider 1, a die seat 7 is commonly connected to the bottom of the driving slider 1 and the reciprocating slider body 2, the first roller wedge 3 is arranged on the outer side of the reciprocating slider body 2, and a second roller wedge 4 is also arranged on the outer side of the first roller wedge 3; a cylinder body 5 is connected to one end of the driving slider 1, and a reverse side block 6 is also arranged on the surface of the die seat 7; a nitrogen cylinder body 8 is arranged on the outer side of the reciprocating slider body 2, a driving roller mounting seat 20 is arranged on the side of the reciprocating slider body 2 away from the nitrogen cylinder body 8, and a pre-driving roller 9 is mounted on the driving roller mounting seat 20; a first working roller 10 is arranged below the first roller wedge 3, a second working roller 11 is arranged below the second roller wedge 4, and there are two nitrogen cylinder bodies 8, the two nitrogen cylinder bodies 8 are coaxially arranged, and the ends of the two nitrogen cylinder bodies 8 are commonly A movable guide column 12 is connected, and the outer side of the movable guide column 12 is slidably connected to a limiting block 13. A nitrogen cylinder top block 14 is arranged on the outer side of one nitrogen cylinder body 8, and pressure plates 15 are installed on the outer sides of the two nitrogen cylinder bodies 8. A guide plate 21 is arranged on the outer side of the reciprocating slider body 2, and a presser body 25 is arranged above the reciprocating slider body 2. One side of the reciprocating slider body 2 is a reciprocating slider force support surface A, and the other side of the reciprocating slider body 2 is a reciprocating slider control surface C. The bottom of the reciprocating slider body 2 is the reciprocating slider bottom surface B. The pressures of the presser body 25 on the reciprocating slider body 2 are respectively the presser pressure F1, the first flanging force F2 and the second flanging force F3, and the pressure of the pre-drive roller 9 is the driving force F4. The force and stroke of the two nitrogen cylinder bodies 8 are the same, a rolling structure is formed between the first roller wedge 3 and the first working roller 10, a rolling structure is formed between the second roller wedge 4 and the second working roller 11, and a sliding structure is formed between the limiting block 13 and the movable guide column 12.

[0025] In specific implementation, the first working roller 10 and the second working roller 11 are respectively the working drives of the first roller bevel 3 and the second roller bevel 4. The first working roller 10 and the second working roller 11 are respectively in line contact with the first roller bevel 3 and the second roller bevel 4. At the same time, the pre-driving roller 9 is pre-started on the reciprocating slider body 2, and the pre-driving roller 9 and the driving surface are also in line contact. In this way, the contact area can be reduced, the wear of the driving surface is reduced, and the mute effect is achieved. Since the reciprocating slider body 2 is subjected to forces in multiple directions, mainly the presser pressure F1, the first flanging force F2 and The second flanging force F3 has a larger force component in the moving direction, and the contact surface between the reciprocating slider body 2 and the driving slider 1 is designed to be in plane contact, so that the working force can be better borne, the working stability of the reciprocating slider body 2 is ensured, and the guide plate 21 and the reverse side block 6 are added to prevent the pre-driving roller 9, the first working roller 10 and the second working roller 11 from excessive wear and premature failure. The pre-driving roller 9 has a diameter of 62 mm and a length of 64 mm, the first working roller 10 has a diameter of 62 mm and a length of 30.5 mm, and the second working roller 11 has a diameter of 90 mm and a length of 70.5 mm;

[0026] Since the movement direction V of the reciprocating slider body 2 is inconsistent with the force direction of the reciprocating slider body 2, the presser pressure F1, the first flanging force F2, the second flanging force F3 and the driving force F4, the reciprocating slider body 2 is subjected to different forces in multiple directions and at multiple times, which affects the movement state of the reciprocating slider body 2, resulting in different forces and contact states on the guide sliding surface. The reciprocating slider force support surface A, the reciprocating slider bottom surface B and the reciprocating slider control surface C of the reciprocating slider body 2 change with different forces. Therefore, it is necessary to control the distribution of guide elements and gap values ​​on the reciprocating slider body 2. Since the normal gaps of the reciprocating slider force support surface A, the reciprocating slider bottom surface B and the reciprocating slider control surface C are 0.05-0.08mm, it is difficult to ensure the stable operation of the reciprocating slider body 2. The gap of the reciprocating slider force support surface A can be designed to be 0mm, the reciprocating slider bottom surface B can be designed to be 0.02-0.03mm, and the reciprocating slider control surface C can be designed to be 0.01-0.02mm design, so as to ensure that the reciprocating slider body 2 can work normally, the first roller wedge 3 and the second roller wedge 4 are lower wedges, and the clearance between the first roller wedge 3 and the second roller wedge 4 is greater than 20mm, so as to determine the stroke of the first roller wedge 3 and the second roller wedge 4. After the negative angle flanging is completed, the clearance between the workpiece and the reciprocating slider body 2 is greater than 5mm, so as to determine the actual stroke of the reciprocating slider body 2, and the actual retreat stroke of the reciprocating slider body 2 is large, resulting in a large stroke of the driving slider 1. The size of the cylinder body 5 is not easy to select, and at the same time, it is limited by the size of the mold base 7. The bevel angle of the driving roller mounting seat 20 and the driving angle of the driving slider 1 are set to 45 degrees, which can greatly reduce the stroke of the driving slider 1, thereby making it easy to select the size of the cylinder body 5 and meet the size requirements of the mold base 7, and the movable guide column 12, the nitrogen cylinder body 8 and the pressure plate 15 are a whole.

[0027] See also Figure 1-Figure 7 It can be seen that the length of the movable guide column 12 can be changed through the stroke specification of the nitrogen cylinder body 8, the limit block 13 can ensure the safe movement of the movable guide column 12, so that the stroke movement of the reciprocating slider body 2 can be increased, and at the same time, the first working roller 10 cooperates with the first roller wedge 3, and the second working roller 11 cooperates with the second roller wedge 4, so that the flanging and cutting functions in different directions can be realized. The cylinder body 5 can reciprocate the driving slider 1, and the nitrogen cylinder body 8 can reciprocate the reciprocating slider body 2. When the reciprocating slider body 2 moves, it can drive the pre-drive roller 9 to move. The large stroke is achieved by two nitrogen cylinder bodies 8 with the same force and stroke in the movable guide column 12, so that the manipulator can normally pick up and place the workpiece, and control the movement gap of the reciprocating slider body 2 to ensure the normal movement and work of the reciprocating slider body 2. At the same time, this method has a simple structure and is easy to process and manufacture. It has the advantages of low cost and high efficiency to solve the problem of silent movement of the negative angle flanging and cutting mechanism in limited space.

[0028] In summary, when the slider control device capable of controlling the movement gap of the slider is used, the first working roller 10 and the second working roller 11 are respectively driven by the first roller bevel 3 and the second roller bevel 4. There is line contact between the first working roller 10 and the first roller bevel 3, and between the second working roller 11 and the second roller bevel 4. At the same time, the pre-drive roller 9 is pre-started on the reciprocating slider body 2, and there is also line contact between the pre-drive roller 9 and the driving surface. In this way, the contact area can be reduced, the wear of the driving surface is reduced, and a silent effect is achieved. At the same time, the cooperation between the first working roller 10 and the first roller bevel 3, and the cooperation between the second working roller 11 and the second roller bevel 4 can realize the flanging and cutting functions in different directions. The cylinder body 5 can push the driving slider 1 back and forth, the nitrogen cylinder body 8 can push the reciprocating slider body 2 back and forth, and when the reciprocating slider body 2 moves, it can drive the pre-drive roller 9 to move. The large stroke is achieved by two nitrogen cylinder bodies 8 with the same force and stroke in the movable guide column 12, so that the manipulator can normally pick up and place the workpiece, and control the movement gap of the reciprocating slider body 2 to ensure the normal movement and work of the reciprocating slider body 2. At the same time, this method has a simple structure and is easy to process and manufacture. It has the advantages of low cost and high efficiency to solve the problem of silent movement of the negative angle flanging tool mechanism under limited space conditions.
