Description

Technical Field

[0001] This invention relates to the field of auxiliary components for metal stamping dies, and in particular to a guide sleeve reinforcement mounting structure with anti-lateral force offset function. Background Technology

[0002] Metal stamping dies are equipment used to form parts by applying pressure to sheet metal through the closing of upper and lower dies. A guide sleeve is installed on the upper die holder, which cooperates with the guide post of the lower die holder to form a guide pair. This structure can constrain the relative movement of the upper and lower dies, maintain a stable blanking clearance, and resist the lateral forces generated during the stamping process, helping to ensure the consistency of parts in mass production.

[0003] Existing guide sleeves mostly form a clearance fit with guide posts through precision nesting, which can initially meet the guiding accuracy requirements. However, with continuous production, the mating surfaces wear down, the clearance gradually increases, and the offset under lateral forces accumulates. Once the offset exceeds the limit, the accuracy is difficult to restore, and the entire guide sleeve usually needs to be replaced, increasing maintenance costs and downtime. Summary of the Invention

[0004] Therefore, it is necessary to provide a reinforced mounting structure for guide sleeves with anti-lateral force offset function to address the problem that the accuracy of existing guide sleeves is difficult to restore after the mating clearance increases due to wear, requiring the entire sleeve to be replaced, which increases maintenance costs and downtime.

[0005] A guide sleeve reinforcement mounting structure with anti-lateral force offset function includes: a guide sleeve body and a uniformly distributed reinforcement mounting mechanism. The outer surface of the guide sleeve body is provided with uniformly distributed positioning grooves, and the inner surface of the guide sleeve body is provided with uniformly distributed guide cavities that are respectively connected to adjacent positioning grooves.

[0006] In one embodiment, the reinforcing mounting mechanism includes a mounting base inserted into the interior of a positioning groove. The mounting base has a mounting cavity communicating with the guide cavity at one end. A threaded seat is slidably connected inside the mounting cavity. An adjusting bolt, rotatably connected to the mounting cavity, is threaded onto the inner side of the threaded seat. The head of the adjusting bolt extends through the mounting cavity and outwards to the exterior of the mounting base. The end of the threaded seat facing away from the adjusting bolt head extends into the interior of the guide cavity. A placement cavity is formed at the end of the threaded seat facing away from the adjusting bolt head. A roller is rotatably connected inside the placement cavity. The surface of the roller facing away from the adjusting bolt head extends into the inner side of the guide sleeve body.

[0007] In one embodiment, the threaded seat has a countersunk hole and a threaded hole on its two vertical end faces parallel to the axis of the adjusting bolt, respectively. The relative openings of the countersunk hole and the threaded hole are connected to the placement cavity. A positioning hole is provided at the axis of the roller, which is connected to both the countersunk hole and the threaded hole. A smooth bolt is inserted into the countersunk hole, and the shank of the smooth bolt passes through the countersunk hole and the positioning hole in sequence and is threadedly connected to the threaded hole.

[0008] In one embodiment, the placement cavity, countersunk hole, threaded hole, roller and positioning hole are used in pairs and there are two of each. The two placement cavities are symmetrically distributed on the upper and lower sides of the axis of the adjusting bolt.

[0009] In one embodiment, the partial cross-sectional shapes of the guide cavity and the mounting cavity in contact with the threaded seat are both rectangular and matched, and the head of the smooth bolt contacts one of the vertical inner walls of the guide cavity.

[0010] In one embodiment, balls are embedded in both vertical end faces of the roller, and the surface of the balls facing away from the roller axis contacts the vertical inner wall of the mounting cavity.

[0011] In one embodiment, the number of balls disposed on the same vertical end face of the roller is not less than five, and the balls disposed on the same vertical end face of the roller are evenly distributed in a ring around the axis of the roller.

[0012] In one embodiment, the horizontal cross-sectional shape of the mounting base is U-shaped, and the width of the horizontal cross-section of the mounting base gradually narrows from top to bottom.

[0013] In one embodiment, the head of the adjusting bolt is located in the recess of the U-shaped cross-section of the mounting base, which is a tungsten carbide component.

[0014] In one embodiment, a positioning seat is fixedly connected to the vertical end face of the mounting base facing away from the head of the adjusting bolt. A locking bolt is inserted into the inner side of the positioning seat, and the shank of the locking bolt extends through the outside of the positioning seat.

[0015] In one embodiment, the positioning seat and the locking bolt are used together in pairs, and the two positioning seats are symmetrically fixed to the vertical end face of the mounting seat axis.

[0016] 1. The above-mentioned guide sleeve reinforced installation structure with anti-lateral force offset function realizes online compensation for the clearance between the guide sleeve body and the guide post by actively driving the threaded seat and roller radial feed through adjusting bolts. This eliminates the clearance accumulation caused by wear, effectively maintains the stability of the punching clearance, avoids downtime losses caused by the need to replace the entire guide sleeve after wear, and extends the effective service life of the guide sleeve. 2. In this mechanism, the rollers transform the sliding friction between the traditional guide sleeve and guide post into rolling friction, continuously providing rolling support to resist lateral forces under active clamping. At the same time, the smooth rod bolts serve as roller shafts, fasteners, and anti-rotation blocks, and work in conjunction with the symmetrical double rollers and balls to integrate gap compensation, low-resistance support, and circumferential locking functions in a compact space, enhancing the rigidity against multi-directional lateral force offset.

[0025] The following is combined with Figure 1 - Figure 8 The present invention describes a guide sleeve reinforced mounting structure with anti-lateral force offset function.

[0026] In one embodiment, a guide sleeve reinforcement mounting structure with anti-lateral force offset function includes: a guide sleeve body 100 and a uniformly distributed reinforcement mounting mechanism 200. The outer surface of the guide sleeve body 100 is provided with uniformly distributed positioning grooves 110, and the inner surface of the guide sleeve body 100 is provided with uniformly distributed guide cavities 120 that are respectively connected to adjacent positioning grooves 110.

[0027] The upper die in the stamping die is used in conjunction with the guide sleeve reinforcement installation structure. The upper die base has evenly distributed guide sleeve mounting holes on its inner top wall, and the upper die base also has evenly distributed threaded mounting grooves that are evenly distributed in a ring around the corresponding guide sleeve mounting holes.

[0028] like Figure 2 - Figure 8As shown, the reinforced mounting mechanism 200 includes a mounting base 210, which is inserted into the positioning groove 110. The mounting base 210 supports the entire adjustment mechanism and transmits lateral force to the upper mold base, providing a stable sliding foundation for the threaded seat 220. The end of the mounting base 210 facing the guide cavity 120 has a mounting cavity 211 communicating with the guide cavity 120. This guide cavity 120 communicates with the positioning groove 110, providing radial adjustment space for the threaded seat 220 and the roller 240, allowing the roller 240 to move from inside the guide sleeve body 100. The active clamping of the guide post achieves adjustable rolling support, thereby actively constraining the relative position of the guide sleeve and the guide post in the initial state, effectively resisting the offset caused by lateral forces, and maintaining the stability of the punching clearance. The mounting cavity 211 provides space for the radial movement of the threaded seat 220 and the roller 240. The threaded seat 220 is slidably connected inside the mounting cavity 211. The threaded seat 220 acts as the motion conversion core, converting the rotational motion of the adjusting bolt 230 into the radial linear motion of itself and the roller 240, thereby achieving the clamping of the roller 240 on the guide post and the elimination of clearance. The inner thread of the threaded seat 220 is threadedly connected to an adjusting bolt 230 that is rotatably connected to the mounting cavity 211. The adjusting bolt 230 serves as an adjustment input, allowing for precise control of the radial position of the threaded seat 220 and enabling active compensation of wear clearance. The head of the adjusting bolt 230 extends through the mounting cavity 211 and outwards from the mounting seat 210. The end of the threaded seat 220 facing away from the head of the adjusting bolt 230 extends into the interior of the guide cavity 120. A placement cavity 221 is formed at the end of the threaded seat 220 facing away from the head of the adjusting bolt 230. 1 provides installation space for roller 240 and cooperates with countersunk hole 222 and threaded hole 223 to realize the symmetrical arrangement of double roller 240, increase the support span with guide post, and improve the stiffness against lateral force offset. The roller 240 is rotatably connected inside the placement cavity 221. The roller 240 directly contacts and rolls with the surface of guide post, replacing sliding friction with rolling friction, reducing wear of mating pair, and providing continuous rolling support to resist lateral force under the clamping state. The surface of roller 240 facing away from the head of adjusting bolt 230 penetrates to the inner side of guide sleeve body 100.

[0029] The local cross-sectional shapes of the contact areas between the guide cavity 120 and the mounting cavity 211 and the threaded seat 220 are all matching rectangles. This rectangular mating surface restricts the threaded seat 220 to only translate radially and not rotate, ensuring that when the adjusting bolt 230 is rotated, the threaded seat 220 and the roller 240 only make linear feeds, and the clamping direction is always perpendicular to the guide post axis, making the adjustment action reliable. The head of the smooth bolt 250 contacts one of the vertical inner walls of the guide cavity 120. The head of the smooth bolt 250 is used as a mechanical limit, which together with the rectangular cross-section forms a double anti-rotation, further strengthening the circumferential positioning of the threaded seat 220 during adjustment and operation, avoiding rotational loosening when subjected to lateral force impact, and maintaining the stability of the clamping posture of the roller 240.

[0030] like Figure 2 - Figure 8 As shown, the threaded seat 220 has a countersunk hole 222 and a threaded hole 223 on its two vertical end faces parallel to the axis of the adjusting bolt 230. The countersunk hole 222 accommodates the head of the smooth bolt 250, and the threaded hole 223 cooperates with the smooth bolt 250, providing a rotation axis for the roller 240 and reliably constraining the roller 240 within the placement cavity 221 and subjecting it to shear by tightening the smooth bolt 250. The relative openings of the countersunk hole 222 and the threaded hole 223 are both connected to the placement cavity 221. A positioning hole 241 is provided at the axis of the roller 240, which communicates with both the countersunk hole 222 and the threaded hole 223. The positioning hole 241 ensures precise positioning of the rotation center of the roller 240 and smooth rolling. The interior of the countersunk hole 222... A smooth bolt 250 is inserted, with its shank passing through the countersunk hole 222 and the positioning hole 241 and threadedly connected to the threaded hole 223. The smooth bolt 250 serves as a roller, a threaded fastener, and an anti-rotation stop. After tightening, the roller 240 is installed, simplifying the structure. The placement cavity 221, countersunk hole 222, threaded hole 223, roller 240, and positioning hole 241 are used in pairs, with two placement cavities 221 symmetrically distributed on the upper and lower sides of the axis of the adjusting bolt 230. This symmetrical arrangement of the double rollers 240 forms a symmetrical support force when the guide post is pressed, which can effectively resist lateral forces from different directions and prevent the guide sleeve body 100 from tilting due to uneven load.

[0031] Both vertical end faces of the roller 240 are embedded with ball bearings 260. The surface of the ball bearings 260 facing away from the axis of the roller 240 contacts the vertical inner wall of the mounting cavity 211. This changes the sliding friction between the end face of the roller 240 and the inner wall of the mounting cavity 211 into rolling friction, reducing rotational resistance and preventing wear of the end face from increasing the axial clearance or causing jamming of the roller 240, thus ensuring the roller 240 rotates flexibly for a long time. There are no fewer than five ball bearings 260 on the same vertical end face of the roller 240. The ball bearings 260 on the same vertical end face of the roller 240 are evenly distributed in a ring around the axis of the roller 240. The fact that there are no fewer than five ball bearings and that they are evenly distributed ensures that the end face of the roller 240 is subjected to uniform force, further reducing rotational resistance and preventing uneven wear from affecting the flexibility of the roller 240. This ensures that the roller 240 can still rotate smoothly and always keep in contact with the guide post after compensation and adjustment.

[0032] The horizontal cross-sectional shape of the mounting base 210 is U-shaped, with the width of the horizontal cross-section gradually narrowing from top to bottom. The U-shaped and narrowing shape creates a wedge-tightening effect when the mounting base 210 mates with the positioning groove 110, making it less prone to slippage under radial loads, improving shear resistance and assembly firmness. At the same time, the concave part of the U-shape can accommodate the head of the adjusting bolt 230, avoiding interference from outward protrusion. The head of the adjusting bolt 230 is located in the concave part of the U-shaped cross-section of the mounting base 210, so that the head of the adjusting bolt 230 does not protrude from the outer edge of the mounting base 210, saving space, avoiding collision interference, and facilitating adjustment by using tools from the side. The mounting base 210 is a component made of tungsten steel, which has high hardness and high wear resistance, and can withstand repeated radial adjustment forces and lateral impacts for a long time, avoiding plastic deformation or excessive wear of the mounting base 210 and extending the service life of the mechanism.

[0033] Positioning seats 270 are fixedly connected to the vertical end face of the mounting base 210 opposite to the head of the adjusting bolt 230. Locking bolts 280 are inserted into the inner side of the positioning seats 270, with the shank of the locking bolts 280 extending beyond the positioning seats 270. The positioning seats 270 and locking bolts 280 work together to reliably lock the reinforced mounting mechanism 200 onto the upper mold base, capable of bearing tensile, bending, and shear forces caused by lateral forces, preventing loosening during operation. Simultaneously, online adjustment can be performed by loosening the locking bolts 280 without disassembling the mechanism. Positioning seats 270 and locking bolts 280 are used in pairs, with two positioning seats 270 symmetrically fixed to the vertical end face of the mounting base 210's axis. The two positioning seats 270 form a double-sided fixation, resulting in balanced force and high locking rigidity. Furthermore, the locking bolts 280 use a detachable threaded connection, supporting multiple loosening-adjustment-locking wear compensation processes, thereby shortening maintenance time and avoiding downtime losses caused by the need for complete replacement of the guide sleeve after wear.

[0034] The installation process of the guide sleeve reinforcement structure is as follows: Place the guide sleeve body 100 onto the guide post of the lower mold base. Slide the guide sleeve body 100 vertically along the guide post until it inserts into the guide sleeve mounting hole on the inner top wall of the upper mold base. Take a reinforcement mounting mechanism 200, align the threaded seat 220 with the guide cavity 120, and push it horizontally in. Simultaneously, insert the mounting seat 210 into the positioning groove 110 until the mounting seat 210 and positioning groove 110 are fully inserted and the mounting cavity 211 is connected to the guide cavity 120. Align the openings of the positioning seats 270 on both sides of the mounting seat 210 with the threaded mounting grooves on the inner top wall of the upper mold base corresponding to the guide sleeve mounting holes, and then lock them in place. Bolt 280 is screwed into the threaded mounting groove and locked. Rotate adjusting bolt 230, which drives threaded seat 220 to slide along mounting cavity 211 towards the guide post. Threaded seat 220 drives roller 240 to move radially through smooth bolt 250 until the surface of roller 240 is in contact with the surface of guide post. The installation and adjustment of the remaining reinforcing mounting mechanism 200 are completed according to the above process. At this point, the guide sleeve body 100 forms an active pressing rolling support for the guide post through the evenly distributed rollers 240. In the initial state, it constrains the relative position of the guide sleeve body 100 and the guide post, effectively resisting the offset caused by lateral force and maintaining the stability of the punching gap.

[0035] Wear compensation adjustment process for guide sleeve reinforced mounting structure: After the stamping production causes a gap between the guide sleeve body 100 and the guide post mating surface, loosen the locking bolts 280 of each reinforced mounting mechanism 200 one by one, and rotate the adjusting bolts 230 again to make the threaded seat 220 slide further along the mounting cavity 211. The smooth bolt 250 pushes the roller 240 to press against the guide post surface, eliminating the wear gap and restoring the gapless fit between the roller 240 and the guide post. Then, tighten the locking bolts 280 to complete the gap compensation. This online adjustment method allows the guide sleeve body 100 to continuously constrain the relative position with the guide post without the need for overall replacement after the guide pair wears, resisting the offset caused by lateral force, avoiding downtime and increased maintenance costs due to excessive wear, and ensuring the consistency of batch stamped parts.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
