Description

Technical Field

[0001] This utility model relates to a guiding device, and more specifically, to a side guiding mechanism for a mold. Background Technology

[0002] In the mass production of lithium battery components, various metal structural parts are mainly formed by stamping using blanking dies. To meet the needs of power battery capacity upgrades and improve stamping production efficiency and capacity, stamping dies in the industry have generally been upgraded from single-station, few-row structures to multi-row, multi-station continuous stamping structures. The significant increase in the number of die rows has led to a significant increase in the width, overall size, and weight of the aluminum alloy strip to be produced, placing higher demands on the die strip guiding, positioning accuracy, and operational stability.

[0003] Currently, most existing stamping dies employ a double-sided guide plate gap positioning method for strip guiding, where the distance between the two guide plates is slightly larger than the actual width of the strip to achieve strip feeding. This structure has inherent technical defects: the gap positioning accuracy is low, and wide, heavy-duty aluminum alloy strips are prone to offset and swaying during transport. This not only causes continuous friction with the guide plates but also leads to misalignment of the subsequent guide pins. When positioning fails, the guide pins are prone to hard punching interference with the strip guide holes, causing deformation of the guide holes, edge chipping, and wear and breakage of the guide pins. Furthermore, the long-term friction between the guide plates and the strip causes continuous wear, further exacerbating positioning errors and creating a vicious cycle of accuracy deterioration. This significantly increases die maintenance costs, reduces product stamping accuracy and production yield, and makes it difficult to meet the high-speed, high-precision, and stable large-scale production requirements of multi-row, multi-station dies. Utility Model Content

[0004] This invention provides a side guide mechanism for molds, which solves the problems of low positioning accuracy and easy wear in the existing double-sided guide plate gap positioning method.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a side guide mechanism for a mold, including a lower mold and side guide plates disposed on both sides of the upper surface of the lower mold. The side guide plates on both sides are parallel to each other and define a material strip guide area. The side guide plates are provided with guide grooves distributed along their length direction on the side wall near the material strip guide area. A guide side wall perpendicular to the upper surface of the lower mold and a limiting surface connected to the upper end of the guide side wall are formed in the guide groove. The side guide plate is provided with a mounting cavity penetrating the guide side wall. A movable block and an elastic element that pushes the movable block to move towards the material strip guide area are movably disposed in the mounting cavity. An abutment part is provided on the movable block near the material strip guide area, and the abutment part protrudes outward relative to the guide side wall.

[0006] This invention specifically guides the material strip through a guide zone defined by a side guide plate. The actual structures involved in guiding and limiting include a guide groove and an abutment portion. The elastic element is in a pre-tensioned state, thus applying a certain thrust to the movable block and the abutment portion. When the material strip contacts the abutment portion, this thrust provides a guiding and centering effect, keeping the material strip as close to the center of the guide zone as possible, reducing the chance of direct contact between the material strip and the guide groove, thereby reducing wear and improving positioning accuracy. Furthermore, due to the buffering effect of the elastic element, if the pressure on the abutment portion is too high, the movable block will adaptively retract, thus preventing the material strip from jamming.

[0007] Furthermore, a bearing is rotatably mounted on the movable block near the guide area of ​​the conveyor belt. The bearing's shaft is vertically or nearly vertically positioned, and the bearing portion protrudes outward relative to the guide sidewall. This protruding portion of the bearing constitutes the contact part. This technical solution transforms the friction between the conveyor belt and the contact part into rolling friction, significantly reducing wear on the contact part and shortening subsequent maintenance cycles.

[0008] Furthermore, the mounting cavity is provided with a limiting part, and the movable block is provided with a locking part. Under the pre-tightening action of the elastic element, the locking part tends to move towards the material guide area with the movable block and makes the locking part abut against the limiting part for limiting.

[0009] Furthermore, a guide rod is fixed on the movable block. The guide rod is horizontally positioned and perpendicular to the length direction of the guide strip area. The elastic element is sleeved on the guide rod. A pressure plate is fixed on the side of the mounting cavity opposite to the movable block. The guide rod slides through the pressure plate.

[0010] Furthermore, the lower mold is provided with a plurality of product cavities, which are located within the strip guide area. The side guide plate is composed of a plurality of first side guide blocks and a plurality of second side guide blocks. The first side guide blocks are distributed in the front area of ​​the product cavity, and the second side guide blocks are distributed on both sides and the rear area of ​​the product cavity. The abutting part is located on the first side guide block, and both the first and second side guide blocks are provided with axially collinear guide grooves. Dividing the side guide plate into multiple first side guide blocks and multiple second side guide blocks can significantly reduce material procurement costs and production processing costs.

[0011] Furthermore, the front end of the guide sidewall on any of the guide grooves is chamfered.

[0012] Furthermore, the upper surface of the lower mold is provided with a plurality of floating nail modules, which are located within the guide area of ​​the material strip.

[0013] Furthermore, the feeding side of the lower die extends outward to provide a feeding bracket, and the feeding bracket is provided with several rollers arranged at the same height. The rotation axis of the rollers is arranged horizontally and perpendicular to the length direction of the material strip guide area.

[0014] In summary, this utility model has the following beneficial effects: 1. The elastic element in the pre-tightened state can apply a certain thrust to the moving block and the contact part. This thrust can provide a certain guiding and centering effect, so that the material strip is kept in the center of the material strip guide area as much as possible, reducing the chance of the material strip directly contacting the guide groove, thereby reducing wear and improving positioning accuracy. 2. A bearing is rotatably provided on the movable block near the guide area of ​​the material belt. The protruding part of the bearing constitutes the contact part, which changes the friction between the material belt and the contact part into rolling friction. This can significantly reduce the wear of the contact part and reduce the maintenance cycle in the later stage. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example: See Figure 1 , Figure 2 and Figure 3 A side guide mechanism for a mold includes a lower mold 10 and side guide plates 20 disposed on both sides of the upper surface of the lower mold 10. The side guide plates 20 are parallel to each other and define a material guide area. The side wall of the side guide plate 20 near the material guide area is provided with guide grooves 30 distributed along its length direction. A guide side wall 31 perpendicular to the upper surface of the lower mold 10 and a limiting surface 32 connected to the upper end of the guide side wall 31 are formed in the guide groove 30. The side guide plate 20 is provided with a mounting cavity 21 that penetrates the guide side wall 31. A movable block 22 and an elastic element 23 that pushes the movable block 22 to move towards the material guide area are movably disposed in the mounting cavity 21. The movable block 22 is provided with an abutment part 24 near the material guide area. The abutment part 24 protrudes outward relative to the guide side wall 31.

[0022] In this embodiment, the material strip 70 is guided by the material strip guide area defined by the side guide plate 20. The actual structures involved in guiding and limiting are the guide groove 30 and the abutment part 24. The elastic element 23 is in a pre-tightened state, so a certain thrust can be applied to the movable block 22 and the abutment part 24. When the material strip 70 contacts the abutment part 24, this thrust can provide a certain guiding and centering effect, thereby keeping the material strip 70 as close as possible to the center of the material strip guide area, reducing the chance of the material strip 70 directly contacting the guide groove 30, thereby reducing wear and improving positioning accuracy. Furthermore, due to the buffering effect of the elastic element 23, when the pressure on the abutment part 24 is too great, the movable block 22 will adaptively retract, thereby preventing the material strip 70 from jamming.

[0023] For details, see Figure 2 and Figure 3 Two bearings 25 are rotatably mounted on the movable block 22 near the guide area of ​​the conveyor belt. The shafts of the bearings 25 are vertically oriented, and a portion of the bearing 25 protrudes outward relative to the guide sidewall 31, forming the contact portion 24. This technical solution transforms the friction between the conveyor belt 70 and the contact portion 24 into rolling friction, significantly reducing wear on the contact portion 24 and shortening the maintenance cycle. It also prevents feeding difficulties or jamming due to the uneven surface of the conveyor belt 70.

[0024] For details, see Figure 3 The mounting cavity 21 is provided with a limiting part 26, and the movable block 22 is provided with a locking part 27. Under the pre-tightening action of the elastic element 23, the locking part 27 tends to move towards the guide area of ​​the material belt with the movable block 22, so that the locking part 27 abuts against the limiting part 26 and is limited. When the locking part 27 abuts against the limiting part 26 and is limited, the two bearings 25 protrude 2 to 5 mm from the guide sidewall 31.

[0025] For details, see Figure 2 A guide rod 28 is fixed on the movable block 22, which is horizontal and perpendicular to the length of the guide strip area. The guide rod 28 can actually be made of equal height screws. The elastic element 23 is sleeved on the guide rod 28. A pressure plate 29 is fixed on the side of the mounting cavity 21 that is away from the movable block 22. The guide rod 28 slides through the pressure plate 29.

[0026] For details, see Figure 1 The lower die 10 is provided with several product dies 40 located within the strip guide area. The side guide plate 20 consists of four first side guide blocks 201 and six second side guide blocks 202. Each first side guide block 201 is distributed in the front area of ​​the product die 40, and each second side guide block 202 is distributed on both sides and the rear area of ​​the product die 40. The contact part 24 is located on the first side guide block 201. Both the first side guide block 201 and the second side guide block 202 are provided with axially collinear guide grooves 30. By dividing the side guide plate 20 into multiple first side guide blocks 201 and multiple second side guide blocks 202, the material procurement cost and production processing cost can be significantly reduced. At the same time, since the positioning accuracy requirement of the strip 70 decreases after punching, the contact part 24 is no longer needed for high-precision guiding and positioning.

[0027] For details, see Figure 3 Each guide sidewall 31 on any guide groove 30 has a chamfer 33 at its front end.

[0028] For details, see Figure 1Several floating nail modules 50 are provided on the upper surface of the lower die 10 and within the strip guide area. The floating nail modules 50 lift the strip 70 away from the die cavity by relying on the elastic floating effect, reducing the friction and scratching of the strip 70. With the help of side limit constraint, the strip 70 is offset laterally, improving the alignment accuracy of the guide pin, and solving the industry pain points of wide strip 70 sagging due to its own weight, feeding deviation, and guide pin damage.

[0029] For details, see Figure 1 and Figure 4 The lower die 10 has a feeding bracket 60 extending outward from the feeding side. The feeding bracket 60 has several rollers 61 arranged at the same height. The rotation axis of the rollers 61 is horizontal and perpendicular to the length direction of the material strip guide area. By setting the feeding bracket 60, the material strip can be prevented from scratching the lower die 10, and it is also easier to connect with the material strip feeding device more smoothly.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
