Description

Technical Field

[0001] This invention belongs to the field of press technology, specifically relating to a slider structure and a press. Background Technology

[0002] A press processes metal parts by applying high pressure to them, causing plastic deformation and fracture. A press is driven by a motor through a transmission mechanism, which in turn drives the working mechanism to process the workpiece. Presses are generally classified into three main categories: screw presses, crank presses, and hydraulic presses. The slide block on a press is typically connected to an external column via guide rails. To ensure proper operation of the guide rails, an appropriate clearance must be maintained between the sliding surfaces. Too small a clearance increases friction, while too large a clearance reduces guiding accuracy.

[0003] The existing press has the following problems:

[0004] It is not possible to precisely adjust the position of each guide rail individually after the guide rails wear out, so as to ensure that the guide rails maintain an appropriate clearance. Summary of the Invention

[0005] In view of the above-mentioned defects or improvement needs of the prior art, the present invention provides a slider structure and a press, the purpose of which is not only to form an eight-sided guide rail structure through four first guide rails and four second guide rails, but also to allow for individual and precise adjustment of each guide rail to ensure that each guide rail and the external guide post reach a suitable gap.

[0006] In a first aspect, the present invention provides a slider structure, the slider structure including a slider and four adjustment structures, the left and right sides of the slider each have two spaced first square notches, the front and rear sides of the slider each have two spaced second square notches, and the first square notches and second square notches corresponding to each right angle of the slider are connected, and each adjustment structure includes a first adjustment component and a second adjustment component.

[0007] The first adjustment component includes a first active wedge, a first driven wedge, a first guide rail, and a first tensioning bolt. The first active wedge is fixed in the first square notch by the first bolt and is spaced apart from the first side of the first square notch to adjust the distance between the first active wedge and the first side of the first square notch. One side of the first active wedge and the second side of the first square notch are slidably engaged. The first driven wedge is fixed on the first side of the first square notch by the second bolt. The opposite sides of the first driven wedge and the first active wedge are first inclined surfaces, and the two first inclined surfaces are slidably engaged. The first guide rail is fixed on the side of the first driven wedge facing away from the first active wedge and is parallel and spaced apart from the second side of the first square notch. The first tensioning bolt is inserted into the slider and passes through the first active wedge and connects to the first driven wedge.

[0008] The second adjusting assembly includes a second active wedge, a second driven wedge, a second guide rail, a positioning post, and a second tensioning bolt. One end of the positioning post is vertically inserted into the first side of the second square notch, and the other end of the positioning post has two spaced first guide surfaces parallel to the second side of the second square notch. The second driven wedge is fixed to the first side of the second square notch and sleeved on the positioning post. The top of the second active wedge has a protrusion, and an adjusting bolt connected to the top of the second driven wedge is movably inserted into the protrusion. The opposite sides of the second active wedge and the second driven wedge are the first... The second inclined surface has two sliding engagements. The second active inclined wedge has a waist-shaped hole. The positioning post is inserted into the waist-shaped hole, and the waist-shaped hole has two second guide surfaces that slide with the first guide surface. The second guide rail is parallel and spaced apart from the first side of the second square notch. The second guide rail is movably sleeved on the outer periphery of the other end of the positioning post to move along the axial direction of the positioning post. Each second guide rail is spaced apart from and perpendicular to the corresponding first guide rail. The second tension bolt is inserted into the slider and passes through the second driven inclined wedge and the second active inclined wedge before connecting to the second guide rail.

[0009] Optionally, the first side of the second square notch has a circular groove and an arc-shaped positioning groove that are interconnected. A positioning flange is coaxially fixedly sleeved on the middle part of the positioning column. The positioning flange is coaxially inserted into the circular groove. The positioning flange has a notch to form a positioning plane. A limiting block is inserted into the arc-shaped positioning groove. One side of the limiting block is provided with a limiting surface that abuts against the positioning plane.

[0010] Optionally, the limiting block has a positioning shaft, the axis of the positioning shaft is parallel to the limiting surface, the arc-shaped positioning groove has a blind hole, and the positioning shaft is coaxially inserted into the blind hole.

[0011] Optionally, a plurality of spaced connecting bolts are inserted into the outer periphery of the positioning flange to connect the slider.

[0012] Optionally, the second adjustment component further includes a side guard block, one end of which is fixedly connected to the second driven wedge block, and the other end of which protrudes from the second active wedge block to limit the movement of the second active wedge block.

[0013] Optionally, the side guard block and the second active wedge block are arranged at intervals, and the interval between the side guard block and the second active wedge block is 0.10-0.20mm.

[0014] Optionally, a first set screw is inserted into the first active wedge block. The first set screw passes through the first active wedge block and is parallel to the first bolt, so as to abut against the first side of the first square notch.

[0015] Optionally, a second set screw is inserted into the protrusion, the second set screw passing through the protrusion and parallel to the adjusting bolt, so as to abut against the top of the second driven wedge block.

[0016] Optionally, the second adjustment assembly further includes a flat plate seat, which is located between the second guide rail and the second active wedge block, and the second guide rail is fixed parallel to the flat plate seat. The flat plate seat is movably sleeved on the outer periphery of the other end of the positioning post, and the second tensioning bolt passes through the second driven wedge block and the second active wedge block and connects to the flat plate seat.

[0017] In a second aspect, the present invention provides a press comprising a slider structure as described in the first aspect.

[0018] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art are as follows:

[0019] For the slider structure provided in this embodiment of the invention, when it is necessary to reduce the gap between the first guide rail and the external column on the left and right sides of the slider, firstly, the first bolt is tightened so that the first active wedge block is tightly against the second side b of the first square notch and moves towards the first side a. At this time, the first inclined surface of the first active wedge block will press the first driven wedge block to move outward for fine adjustment. Then, the second bolt on the first driven wedge block is tightened, so that the first driven wedge block is tightly against the first side a of the first square notch. Finally, the first tension bolt is tightened to fasten the first active wedge block and the first driven wedge block to the second side b. In this process, the first guide rail moves outward, and during this movement, the first guide rail remains parallel to the second side b of the first square notch, while the distance between the first guide rail and the first side a remains constant. Only the distance between the plane of the first guide rail and the second side b is increased, thus ensuring precise movement of the first guide rail in the single direction closest to the outer column (ensuring that the first guide rail and the guide rail on the outer column are always aligned), thereby precisely reducing the gap between the first guide rail and the outer column. Conversely, when it is necessary to increase the gap between the first guide rail and the outer column, simply reverse the direction of the first bolt, while keeping the other steps the same.

[0020] Regarding the second guide rails on the front and rear sides of the slider, when it is necessary to reduce the gap between the second guide rail and the outer column, firstly, tighten the adjusting bolt. During the tightening process, the adjusting bolt will compress and drive the second active wedge block to move downward. Under the guidance of the two first guide surfaces on the positioning column, the second active wedge block will vertically adjust downward along the second inclined surface to the left. Under the guidance of the outer periphery of the positioning column, the second guide rail will move outward (due to the restriction of the first guide surface, the second guide rail cannot rotate at this time). Finally, the second driven wedge block and the second active wedge block are tightened and secured to the first side c of the second square notch by the second tensioning bolt. During this process, the second guide rail moves outward, and during this movement, the second guide rail remains parallel to the first side c of the second square notch, while the distance between the second guide rail and the second side d remains constant. Only the distance between the plane of the second guide rail and the first side c is increased, thus ensuring the precise movement of the second guide rail in the single direction closest to the outer column (ensuring that the second guide rail and the guide rail on the outer column are always aligned), thereby precisely reducing the gap between the second guide rail and the outer column. Conversely, when it is necessary to increase the gap between the second guide rail and the outer column, simply reverse the direction of the adjusting bolt, while keeping the other steps the same.

[0021] In addition, the first guide rail and the second guide rail of this slider structure form a surface guide rail structure, which makes the slider sliding stable. By precisely adjusting each first guide rail and the second guide rail respectively, each surface guide rail can be individually and precisely adjusted to ensure that each guide rail and the external guide post reach a suitable gap.

[0022] In other words, the slider structure provided in this embodiment of the invention not only forms a surface guide rail structure through a first guide rail and a second guide rail, which makes the slider sliding stable, but also allows for individual and precise adjustment of each surface guide rail to ensure that each guide rail and the external guide post reach a suitable gap.

[0042] Figure 1 This is a schematic diagram of a slider structure provided in an embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of the part, combined with Figure 1 and Figure 2 As shown, the slider structure includes slider 1 and four adjustment mechanisms. Figure 3 This is a schematic diagram of the slider provided in an embodiment of the present invention. Figure 4 yes Figure 3 A magnified view of the part, combined with Figure 3 and Figure 4 As shown, the left and right sides of the slider 1 have two spaced first square notches 11, and the front and rear sides of the slider 1 have two spaced second square notches 12. The first square notches 11 and the second square notches 12 at each right angle of the slider 1 are connected. Each adjustment structure includes a first adjustment component 2 and a second adjustment component 3.

[0043] Figure 5 This is a cross-sectional view of the first adjustment component provided in an embodiment of the present invention, such as... Figure 5As shown, the first adjusting assembly 2 includes a first active wedge block 21, a first driven wedge block 22, a first guide rail 23, and a first tensioning bolt 24. The first active wedge block 21 is fixed inside the first square notch 11 by the first bolt 211 and is spaced apart from the first side a of the first square notch 11 to adjust the distance between the first active wedge block 21 and the first side a of the first square notch 11. One side of the first active wedge block 21 and the second side b of the first square notch 11 are in sliding engagement. The first driven wedge block 22 is connected to the first guide rail 23 by the first guide rail 24. Two bolts 221 are fixed on the first side a of the first square notch 11, and the opposite sides of the first driven wedge block 22 and the first active wedge block 21 are the first inclined surfaces 25, and the two first inclined surfaces 25 are in sliding fit. The first guide rail 23 is fixed on the side of the first driven wedge block 22 facing away from the first active wedge block 21, and is parallel and spaced from the second side b of the first square notch 11. The first tensioning bolt 24 is inserted into the slider 1, and the first tensioning bolt 24 passes through the first active wedge block 21 and connects to the first driven wedge block 22.

[0044] Figure 6 This is a cross-sectional view of the second adjustment component provided in an embodiment of the present invention, such as... Figure 6 As shown, the second adjustment component 3 includes a second active wedge block 31, a second driven wedge block 32, a second guide rail 33, a positioning post 34, and a second tensioning bolt 35. Figure 7 This is a schematic diagram of the positioning column provided in an embodiment of the present invention, as shown below. Figure 7 As shown, one end of the positioning post 34 is vertically inserted into the first side c of the second square notch 12. The other end of the positioning post 34 has two spaced first guide surfaces 341 parallel to the second side d of the second square notch 12. The second driven wedge block 32 is fixed on the first side c of the second square notch 12 and sleeved on the positioning post 34. The top of the second active wedge block 31 has a protrusion 311. An adjusting bolt 312 connected to the top of the second driven wedge block 32 is movably inserted into the protrusion 311. The sides opposite to the second active wedge block 31 and the second driven wedge block 32 are second inclined surfaces 36, and the two second inclined surfaces 36 slide in fit. The second active wedge block 31 is provided with a waist-shaped hole 314 (see...). Figure 8 The positioning post 34 is inserted into the waist-shaped hole 314, and the waist-shaped hole 314 has two second guide surfaces 315 that slide with the first guide surface 341. The second guide rail 33 is parallel and spaced apart from the first side c of the second square notch 12, and the second guide rail 33 is movably sleeved on the outer periphery of the other end of the positioning post 34 so as to move along the axial direction of the positioning post 34. Each second guide rail 33 is spaced apart from and perpendicular to the corresponding first guide rail 23. The second tensioning bolt 35 is inserted into the slider 1, and the second tensioning bolt 35 passes through the second driven wedge block 32 and the second active wedge block 31 and then connects to the second guide rail 33.

[0045] For a slider structure provided in this embodiment of the invention, regarding the first guide rails 23 on the left and right sides of the slider 1, when it is necessary to reduce the gap between the first guide rails 23 and the external column, firstly, the first bolt 211 is tightened so that the first active wedge block 21 is tightly against the second side b of the first square notch 11 and moves towards the first side a. At this time, the first inclined surface 25 of the first active wedge block 21 will press the first driven wedge block 22 to adjust outward movement. Then, the second bolt 221 on the first driven wedge block 22 is tightened, and the first driven wedge block 22 is tightly against the first side a of the first square notch 11. Finally, the first tensioning bolt 24 is tightened, and the first active wedge block 21 and the first driven wedge block 22 are fastened to the second side b by the first tensioning bolt 24 (see Figure 5 In this process, the first guide rail 23 moves outward, and during this movement, the first guide rail 23 remains parallel to the second side b of the first square notch 11, while the distance between the first guide rail 23 and the first side a remains constant. Only the distance between the plane of the first guide rail 23 and the second side b is increased, thus ensuring the precise movement of the first guide rail 23 in the single direction closest to the external column (ensuring that the first guide rail 23 and the guide rail on the external column are always aligned), thereby precisely reducing the gap between the first guide rail 23 and the external column. Conversely, when it is necessary to increase the gap between the first guide rail 23 and the external column, simply reverse the rotation of the first bolt 211, while keeping the other steps the same.

[0046] Regarding the second guide rail 33 on the front and rear sides of slider 1, when it is necessary to reduce the gap between the second guide rail 33 and the external column, firstly, tighten the adjusting bolt 312. During the tightening process, the adjusting bolt 312 will squeeze and drive the second active wedge block 31 to move downward. Under the guidance of the two first guide surfaces 341 on the positioning column 34 (the sliding engagement of the first guide surface 341 and the second guide surface 315), the second active wedge block 31 will move vertically downward to the left along the second inclined surface 36. Under the guidance of the outer periphery of the positioning column 34, the second guide rail 33 will move outward (due to the restriction of the first guide surface 341, the second guide rail 33 cannot rotate at this time). Finally, the second driven wedge block 32 and the second active wedge block 31 are tightened and fixed to the first side c of the second square notch 12 by the second tensioning bolt 35 (see Figure 6In this process, the second guide rail 33 moves outward, and during this movement, the second guide rail 33 remains parallel to the first side c of the second square notch 12, while the distance between the second guide rail 33 and the second side d remains constant. Only the distance between the plane of the second guide rail 33 and the first side c is increased, thus ensuring the precise movement of the second guide rail 33 in the single direction closest to the outer column (ensuring that the second guide rail 33 and the guide rail on the outer column are always aligned), thereby precisely reducing the gap between the second guide rail 33 and the outer column. Conversely, when it is necessary to increase the gap between the second guide rail 33 and the outer column, simply reverse the rotation of the adjusting bolt 312, while keeping the other steps the same.

[0047] In addition, the four first guide rails 23 and four second guide rails 33 of this slider structure form an eight-sided guide rail structure, which makes the slider 1 highly stable. By precisely adjusting each first guide rail 23 and second guide rail 33, each guide rail can be individually and precisely adjusted to ensure that each guide rail and the external guide post reach a suitable gap.

[0048] In other words, the slider structure provided in this embodiment of the invention not only forms an eight-sided guide rail structure through four first guide rails 23 and four second guide rails 33, making the slider 1 highly stable in sliding, but also allows for individual and precise adjustment of each guide rail to ensure that each guide rail and the external guide post reach a suitable gap.

[0049] It should be noted that two spaced-apart partitions are typically arranged between the external columns to protect the front and rear sides of the slider 1. The partitions have observation holes in their center. When adjusting the guide rail position, the gap between the partitions and the slider 1 is small, causing interference during the adjustment process. Therefore, in the slider structure of this application, the four second adjustment structures are respectively positioned opposite the partitions. Adjustment can be achieved by adjusting the adjusting bolts 312 from above (the side partitions will not cause interference), while the second tensioning bolts 35 can be conveniently adjusted through the observation holes. In other words, the slider structure provided by this invention not only enables precise adjustment of the gap between the guide rail and the external columns but also effectively avoids interference from the partitions during the adjustment process.

[0050] In addition, corresponding guide rails are also provided on the external columns, forming a sliding engagement with the first guide rail 23 and the second guide rail 33, so that the horizontally arranged slider 1 can rise and fall stably in the vertical direction. The guiding accuracy and stability of the 8-sided guide rail structure provided in this embodiment of the invention are significantly better than those of the 4-sided guide rail (X-type guide rail) structure, and there is no need to provide a sliding groove on the slider 1.

[0051] For example, each side of the slider 1 has a relief groove 13 at the center to facilitate the installation of the first tensioning bolt 24 or the second tensioning bolt 35 through the relief groove 13.

[0052] For example, the second driven wedge block 32 is fixedly mounted on the slider 1 by a plurality of bolts. The protrusion 311 also has a waist-shaped hole in which the adjusting bolt 312 is inserted, so that the movement of the protrusion 311 is not interfered with when the adjusting bolt 312 is turned.

[0053] It should be noted that the first active wedge block 21 has a slotted hole corresponding to the first tensioning bolt 24 to prevent the first tensioning bolt 24 from interfering with the movement of the first active wedge block 21. Similarly, the second driven wedge block 32 has a slotted hole corresponding to the second tensioning bolt 35 to prevent the second tensioning bolt 35 from interfering with the second driven wedge block 32.

[0054] See you again Figure 4 and Figure 7 The first side of the second square notch 12 has a circular groove 121 and an arc-shaped positioning groove 122 that are interconnected. A positioning flange 342 is coaxially fixedly sleeved on the middle of the positioning post 34. The positioning flange 342 is coaxially inserted into the circular groove 121. The positioning flange 342 has a notch to form a positioning plane 343. A limit block 123 is inserted into the arc-shaped positioning groove 122 (see...). Figure 9 The limiting block 123 has a limiting surface 1231 on one side that abuts against the positioning plane 343.

[0055] In the above embodiment, the circular groove 121 is used to insert the positioning flange 342, and the arc-shaped positioning groove 122 is used to insert the limiting block 123. The positioning plane 343 of the positioning flange 342 can be positioned by the limiting surface 1231 of the limiting block 123, thereby realizing the rotation limit of the positioning post 34, and finally realizing the positioning of the first guide surface 341 on the positioning post 34. This ensures that after the positioning post 34 is installed, its first guide surface 341 is always parallel to the second side surface d of the second square notch 12, and provides single-direction guidance for the fine adjustment of the second active wedge block 31, avoiding the back-and-forth swaying of the second active wedge block 31 during the downward movement.

[0056] It is easy to understand that after the positioning flange 342 and the limiting block 123 are inserted, since the limiting surface 1231 of the limiting block 123 abuts against the positioning plane 343 of the positioning column 34, the limiting block 123 and the positioning flange 342 can be prevented from rotating, and thus the positioning column 34 can also be prevented from rotating, ensuring that during the adjustment process, its first guide surface 341 is always parallel to the second side surface d of the second square notch 12.

[0057] For example, the limiting surface 1231 is located in the circular groove 121.

[0058] Furthermore, the limiting block 123 has a positioning shaft 1232, the axis of the positioning shaft 1232 is parallel to the limiting surface 1231, and the arc-shaped positioning groove 122 has a blind hole, in which the positioning shaft 1232 is coaxially inserted.

[0059] In the above embodiments, the positioning shaft 1232 and the limiting block 123 can be positioned and inserted through the blind hole and the arc-shaped positioning groove 122, and the rotation of the positioning shaft 1232 and the limiting block 123 can be effectively prevented.

[0060] For example, a plurality of spaced connecting bolts are inserted into the outer periphery of the positioning flange 342 to connect the slider 1, thereby fixing the positioning flange 342 and further preventing the positioning flange 342 and the positioning column 34 from rotating.

[0061] Figure 10 This is a schematic diagram of the side guard block provided in an embodiment of the present invention, combined with... Figure 2 and Figure 10 As shown, the second adjustment component 3 also includes a side guard block 37. One end of the side guard block 37 is fixedly connected to the second driven wedge block 32, and the other end of the side guard block 37 protrudes from the second active wedge block 31 to limit the second active wedge block 31.

[0062] In the above embodiment, the side guard block 37 can effectively prevent the second active wedge block 31 from moving away from the second side d of the second square notch 12 during the downward movement, thereby limiting the movement of the second active wedge block 31.

[0063] For example, one side of the second active wedge block 31 is in contact with the second side d of the second square notch 12, thereby ensuring that the second active wedge block 31 can only move vertically by the clamping and limiting of the second side d of the second square notch 12 and the side guard block 37, thus ensuring the precise displacement of the second active wedge block 31.

[0064] For example, the side guard block 37 and the second active wedge block 31 are arranged at intervals, and the interval between the side guard block 37 and the second active wedge block 31 is 0.10-0.20mm.

[0065] It is easy to understand that the aforementioned smaller interval can prevent the second active wedge block 31 from rubbing against the side guard block 37 during its movement, while still being able to limit the second active wedge block 31 in case of an accident.

[0066] See you again Figure 3 A first set screw 212 is inserted into the first active wedge block 21. The first set screw 212 passes through the first active wedge block 21 and is parallel to the first bolt 211 so as to abut against the first side of the first square notch 11.

[0067] In the above embodiment, by adjusting the length of the first set screw 212 extending out of the first active wedge block 21, the distance between the first active wedge block 21 and the first side a of the first square notch 11 can be adjusted. On this basis, the first side is connected by the first bolt 211. At this time, the first set screw 212 will push the first active wedge block 21 outward, while the first bolt 211 will pull the first active wedge block 21 inward to ensure that the first active wedge block 21 is stably installed and to prevent the first set screw 212 or the first bolt 211 from loosening.

[0068] Similarly, a second setter screw 313 is inserted into the protrusion 311. The second setter screw 313 passes through the protrusion 311 and is parallel to the adjusting bolt 312, so as to abut against the top of the second driven wedge block 32. The second setter screw 313 pushes the protrusion 311, while the adjusting bolt 312 pulls the protrusion 311 downward to tighten it, ensuring that the protrusion 311 and the second active wedge block 31 are stably installed and preventing the second setter screw 313 or the adjusting bolt 312 from loosening.

[0069] Figure 11 This is a schematic diagram of the structure of the flat plate base provided in an embodiment of the present invention, as shown below. Figure 11 As shown, the second adjustment component 3 also includes a flat plate base 38, which is located between the second guide rail 33 and the second active wedge block 31. The second guide rail 33 is fixed parallel to the flat plate base 38. The flat plate base 38 is movably sleeved on the outer periphery of the other end of the positioning post 34. The second tensioning bolt 35 passes through the second driven wedge block 32 and the second active wedge block 31 and then connects to the flat plate base 38.

[0070] In the above embodiment, the flat plate base 38 not only serves to mount the second guide rail 33, but also cooperates with the second tension bolt 35, avoiding the need for threaded holes on the second guide rail 33 that would match the second tension bolt 35, thus affecting the structural strength of the second guide rail 33. Furthermore, the second guide rail 33 is costly and difficult to manufacture; therefore, the flat plate base 38 is used to mount the second guide rail 33.

[0071] For example, the plate base 38 has a positioning hole 381 (the inner wall of which has two arc-shaped segments and two parallel segments). The shape of the positioning hole 381 is consistent with the shape of the other end of the positioning post 34, so that the second guide rail 33 can only slide along the axial direction of the positioning post 34 and will not rotate.

[0072] For example, both the first guide rail 23 and the second guide rail 33 can be copper rails.

[0073] In summary, this invention is based on four sets of first adjustment components 2, four sets of second adjustment components 3, and a precision slider 1. Through the aforementioned precise structural design, it can form a precise motion guide pair with the precision static guide rail on the external column. The easily worn guide rails are the first guide rail 23 and the second guide rail 33. When the wear value exceeds the use or design allowance of the press, it is only necessary to adjust each of the eight guide rails by an equal amount (by checking and comparing with a feeler gauge) to maintain equal gaps between the guide rails.

[0074] This invention also provides a press, which includes a slider structure as described above.

[0075] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
