Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a device for preventing the bending of continuous die strips for thick materials. Background Technology

[0002] In the automobile manufacturing process, strip materials need to be processed to form different parts. For example, continuous die punching is used to punch the conveyed strip material through the cooperation of the upper and lower dies, so that parts with specific shapes are formed on both sides of the punched strip material. However, in the process of the upper and lower dies acting on the strip material to form parts on both sides, due to the processing precision of the dies and the wear of the dies during long-term use, and when the thickness of the strip material (T=3.2mm) is large, the punching force of the one-out-two dies on the parts on both sides of the strip material is large and uneven. This makes it easy for the strip material to bend to the side with greater force, thus affecting the subsequent processing of parts on the strip material. Utility Model Content

[0003] The purpose of this invention is to provide a device for preventing the bending of the strip in a continuous die for thick products. During the die punching process, the strip can be effectively prevented from bending, and the cost of use is low.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing bending of continuous die strip in thick material products, disposed on at least one side of the strip conveying direction, comprising a drive mechanism, a transverse movement mechanism, and a longitudinal movement mechanism; the drive mechanism is disposed on the upper die; the transverse movement mechanism is slidably disposed on the lower die, and the longitudinal movement mechanism is slidably disposed on the lower die; the transverse movement mechanism includes a transverse movement block and a transverse movement reset assembly, the transverse movement block being slidably disposed laterally on the lower die, and the transverse movement reset assembly being disposed between the lower die and the transverse movement block; the longitudinal movement mechanism includes a longitudinal movement block and a longitudinal movement reset assembly, the longitudinal movement block being slidably disposed vertically on the lower die, and the longitudinal movement reset assembly being disposed between the longitudinal movement block and the lower die, the longitudinal movement block interacting with the transverse movement block; an insert is provided at the upper end of the longitudinal movement block; when the drive mechanism moves downward, it drives the transverse movement block to move towards the longitudinal movement block and drives the longitudinal movement block to move upward, causing the insert to move upward, so that the insert abuts against the side of the strip.

[0005] The above configuration, when the upper and lower dies are closed to punch the strip, the drive mechanism mounted on the upper die exerts a force on the transverse block, causing the transverse block to overcome the elasticity of the transverse reset component and move laterally. At the same time, the transverse block acts on the longitudinal block, causing the longitudinal block to overcome the elasticity of the longitudinal reset component and move vertically, thereby driving the insert to protrude from the strip and abut against at least one side of the strip scrap rib. Since there is an anti-bending device on at least one side along the strip conveying direction, the insert can be fixedly abutted against at least one side of the strip scrap rib during the strip punching process, thus effectively preventing the strip scrap rib from being completely removed and further preventing the strip from bending and deforming. After punching, the upper and lower dies open, and the upper die drives the drive mechanism to move upward, no longer exerting a force on the transverse block. Under the action of the transverse reset component, the transverse block is reset. At the same time, under the action of the longitudinal reset component, the longitudinal block drives the insert to reset, thus not affecting the strip conveying after punching.

[0006] Furthermore, transverse sliding groove assemblies are respectively provided on both sides of the transverse block on the lower mold, and the transverse groove assemblies and the lower mold form transverse grooves that match the transverse block; longitudinal sliding groove assemblies are respectively provided on both sides of the longitudinal block on the lower mold, and the longitudinal groove assemblies and the lower mold form longitudinal grooves that match the longitudinal block.

[0007] The above settings, by setting a horizontal slot, can guide the movement of the horizontal moving block, and by setting a vertical slot, can guide the movement of the vertical moving block.

[0008] Furthermore, a driving inclined surface is provided at the lower end of the driving mechanism; a first inclined surface that cooperates with the driving inclined surface is provided at the end of the transverse block away from the longitudinal block; a second inclined surface is provided at the end of the transverse block near the longitudinal block; and a third inclined surface that cooperates with the second inclined surface is provided at the lower end of the longitudinal block.

[0009] The above configuration allows the driving inclined surface of the drive mechanism to act on the first inclined surface of the transverse block after the upper and lower molds are closed, while the second inclined surface of the transverse block abuts against the third inclined surface on the longitudinal block, thus enabling the transverse block to push the longitudinal block to move in the vertical direction.

[0010] Furthermore, a step is provided at the lower end of the first inclined surface on the transverse block, and a wear-resistant pad is detachably provided on the first inclined surface, with the wear-resistant pad abutting against the step.

[0011] The above settings, by adding wear-resistant pads, can reduce the wear of the transverse block caused by the frequent action of the driving inclined plane, thereby improving the service life of the transverse block. By adding the stepped part, the downward movement of the wear-resistant pads can be better limited.

[0012] Furthermore, the transverse groove assembly is provided in two parts. The transverse groove assembly is fixed to the lower mold by two or more locking members. The transverse groove assembly includes a first fixing block and a second fixing block arranged perpendicular to the first fixing block. One end of the first fixing block is detachably connected to the second fixing block by a locking member. The other end of the first fixing block extends along a direction perpendicular to the second fixing block and forms a transverse groove with the second fixing block and the lower mold. The bottom of the transverse block protrudes downward to form a first protrusion. The two sides of the first protrusion are provided with second protrusions that are detachably connected to the transverse block. The second protrusions protrude from both sides of the transverse block and have the same thickness as the first protrusion. The second protrusion is connected to the transverse block to form an integral part and then slidably connected to the transverse groove.

[0013] With the above configuration, after the convex strip is connected to the transverse block to form an integral part and protrudes from both sides of the transverse block, the transverse block can slide horizontally within the transverse groove formed by the transverse groove assembly located on both sides of the transverse block.

[0014] Furthermore, the transverse resetting assembly is located below the transverse block. The transverse resetting assembly includes a transverse telescopic rod, a transverse spring sleeved on the outside of the transverse telescopic rod, a transverse limiting block, and a transverse fixing block. One end of the transverse telescopic rod is fixedly connected to the transverse limiting block fixed on the lower mold, and the other end of the transverse telescopic rod is embedded in the transverse fixing block. The transverse block is provided with a receiving groove that matches the transverse fixing block. After the locking member passes through the transverse fixing block, it connects the other end of the transverse telescopic rod, the transverse fixing block, and the protrusion to form a whole. The transverse spring is located between the transverse limiting block and the transverse fixing block.

[0015] The above settings enable the transverse reset component and the transverse block to be connected as one unit. Since the transverse limit block of the transverse reset component is fixed on the lower mold, the transverse block will compress the transverse spring and limit the transverse movement distance of the transverse block during the sliding process of the transverse groove. At the same time, the transverse block can be reset under the action of the transverse spring.

[0016] Furthermore, sliders symmetrically arranged about the longitudinal moving block are fixed on both sides of the longitudinal moving block. Two longitudinal groove assemblies are provided, and each longitudinal groove assembly is fixed to the lower mold by two or more locking members. The distance between the longitudinal groove assemblies is greater than the width of the transverse moving block. Each longitudinal groove assembly includes a third fixing block and a third fixing seat perpendicular to the third fixing block. A longitudinal groove matching the slider is formed inside the third fixing block. One end of the third fixing block is fixedly connected to the third fixing seat by a locking member, and the third fixing seat is fixedly connected to the lower mold by a locking member.

[0017] The above configuration allows the longitudinal traverse block to abut against the transverse traverse block via the third inclined surface. This allows the transverse traverse block to act on the longitudinal traverse block, and then slide along the longitudinal groove via the sliders on both sides of the longitudinal traverse block, thus enabling the longitudinal traverse block to move vertically. Since the longitudinal groove assembly is fixedly connected to the lower mold, the longitudinal traverse block can drive the slider to slide within the longitudinal groove. This longitudinal groove limits the slider's movement, allowing the longitudinal traverse block to move vertically.

[0018] Furthermore, the longitudinal repositioning assembly is located at one end away from the transverse block. The longitudinal repositioning assembly includes a longitudinal telescopic rod, a longitudinal spring sleeved on the outside of the longitudinal telescopic rod, a longitudinal limiting block, and a longitudinal fixing block. The longitudinal fixing block is fixedly connected to the longitudinal block to form an integral unit. One end of the longitudinal telescopic rod is fixedly connected to the longitudinal limiting block fixed on the longitudinal fixing frame. The longitudinal fixing frame is fixedly connected to the lower mold. The other end of the longitudinal telescopic rod is fixedly connected to the longitudinal fixing block. The longitudinal spring is located at the longitudinal limiting block and the longitudinal fixing block are fixedly connected.

[0019] The above settings enable the longitudinal shift reset component and the longitudinal shift block to be connected as a whole. Since the longitudinal shift limit block of the longitudinal shift reset component is fixedly connected to the lower mold through the longitudinal shift fixing frame, the longitudinal shift block will compress the longitudinal shift spring and limit the vertical movement distance of the longitudinal shift block during the sliding process of the longitudinal groove. At the same time, the longitudinal shift block can be reset under the action of the longitudinal shift spring.

[0020] Furthermore, the distance from the end face of the transverse block near the longitudinal block to the longitudinal fixing frame is greater than the extension length of the transverse telescopic rod.

[0021] The above settings ensure that the transverse block can move a sufficient distance laterally without being restricted by the longitudinal moving frame during lateral movement.

[0022] Furthermore, the height of the longitudinal groove is greater than the extension distance of the longitudinal telescopic rod.

[0023] The above settings prevent the slider from dislodging from the longitudinal groove during the vertical movement of the longitudinal block. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, the progressive die for preventing thick material products from bending includes a lower die 6 and an upper die 100, and a device for preventing the material strip of the progressive die for preventing thick material products from bending is installed on the progressive die for preventing thick material products from bending.

[0034] like Figure 2-8 As shown, this utility model provides a device for preventing bending of the continuous die material strip of thick materials, which is positioned opposite to the material strip in the conveying direction of 100° (see reference). Figure 6 In this embodiment, at least one side of the material strip 1000 (in the direction of arrow C) is provided with a device to prevent bending of the continuous die material strip for thick materials. Specifically, the device is provided on both sides of the waste rib 01 of the material strip 1000. The device to prevent bending of the continuous die material strip for thick materials includes a drive mechanism, a transverse movement mechanism, and a longitudinal movement mechanism.

[0035] In this utility model, such as Figure 3 As shown, the driving mechanism is a driving block 300 mounted on the upper mold, and a driving inclined surface 301 is provided at the lower end of the driving block 300. The driving block 300 is mounted on the upper template 302, and the upper end of the driving block 300 abuts against the upper mold base 303. The driving block 300 slides through the stripper plate 304 of the upper mold.

[0036] A transverse movement mechanism is mounted on the lower mold 6, and a longitudinal movement mechanism is mounted on the transverse movement mechanism and can slide on the lower mold 6. The transverse movement mechanism includes a transverse block 1, a transverse reset assembly, and a transverse groove assembly 78. The transverse groove assembly 78 is mounted on both sides of the transverse block 1 and fixed to the lower mold 6 to form a transverse groove 9 that matches the transverse block 1. The transverse block 1 slides horizontally within the transverse groove 9. The two ends of the transverse reset assembly, located at the bottom of the transverse block 1, are connected to the lower mold 6 and the transverse block 1, respectively. The end of the transverse block 1 furthest from the longitudinal movement block has a first inclined surface 2, which slopes downwards away from the longitudinal movement block. The transverse block 1 is located near the longitudinal movement block... One end is provided with a second inclined surface 3, which is inclined from top to bottom toward the longitudinal moving block. A step portion 4 is provided on the transverse moving block 1 at the lower end of the first inclined surface 2. The wear-resistant pad 5 is detachably provided on the first inclined surface 2 and abuts against the step portion 4, so that after the upper mold 100 and the lower mold 6 are closed, it acts on the first inclined surface 2 of the transverse moving block 1. Since the second inclined surface 3 matches and abuts against the third inclined surface 17 provided on the longitudinal moving block 16, the transverse moving block 1 can push the longitudinal moving block 16 to move in the vertical direction.

[0037] like Figure 2 and 3 As shown, two transverse groove assemblies 78 are provided. The transverse groove assemblies 78 are fixed to the lower mold 6 by two or more locking members. The transverse groove assembly 78 includes a first fixing block 7 and a second fixing block 8 arranged perpendicular to the first fixing block 7. One end of the first fixing block 7 is detachably connected to the second fixing block 8 by a locking member. The other end of the first fixing block 7 extends in a direction perpendicular to the second fixing block 8 and forms a transverse groove 9 with the second fixing block 8 and the lower mold 6. The first fixing block 7 is fixed on the lower mold, and the bottom of the transverse moving block 1 faces downward. A protruding ridge 10 is formed, and two ridges 11 are provided on both sides of the ridge 10, which are detachably connected to the transverse block 1. The ridges 11 protrude from both sides of the transverse block 1 and have the same thickness as the ridge 10. After the ridges 11 are connected to the transverse block 1 to form an integral part, they are slidably connected to the transverse groove 9. Thus, after the ridges 11 are connected to the transverse block 1 to form an integral part and protrude from both sides of the transverse block 1, the transverse block 1 can slide horizontally within the transverse groove 9 formed by the transverse groove assembly 78 located on both sides of the transverse block 1.

[0038] like Figure 2 and 3As shown, the transverse resetting assembly is located below the protrusion 10. The transverse resetting assembly includes a transverse telescopic rod 12, a transverse spring 13 sleeved on the outside of the transverse telescopic rod 12, a transverse limiting block 15, and a transverse fixing block 14. One end of the transverse telescopic rod 12 is fixedly connected to the transverse limiting block 15 fixed on the lower mold 6 by a locking member. The other end of the transverse telescopic rod 12 is embedded in the transverse fixing block 14. The protrusion 10 is provided with a receiving groove (not shown in the figure) that matches the transverse fixing block 14. After the locking member passes through the transverse fixing block 14, it connects the other end of the transverse telescopic rod 12, the transverse fixing block 14, and the protrusion 10. The transverse spring 13 is integrally formed with the transverse limiting block 15 and the transverse fixing block 14 at both ends, respectively. This allows the transverse reset assembly to be integrally connected with the protrusion 10, and the protrusion 10 and the transverse block 1 to be integrally formed. Since the transverse limiting block 15 of the transverse reset assembly is fixed to the lower mold 6, the transverse block 1, during its sliding motion in the transverse groove 9, will compress the transverse telescopic rod 12 and the transverse spring 13, limiting the transverse movement distance of the transverse block 1. Simultaneously, the transverse block 1 can be reset under the action of the transverse spring 13. In this embodiment, the locking element is a bolt.

[0039] like Figure 2 and 8 As shown, the longitudinal movement mechanism includes a longitudinal movement block 16, a longitudinal movement reset assembly, and a longitudinal groove assembly. The upper end of the longitudinal movement block 16 is provided with an insert 26. The two ends of the longitudinal movement reset assembly, which is located at one end of the longitudinal movement block 16, are respectively connected to the lower mold 6 and the longitudinal movement block 16. The longitudinal groove assembly is located on both sides of the longitudinal movement block 16 and is fixed on the lower mold 6 to form a longitudinal groove 20 that matches the longitudinal movement block 16. The sliders 20a fixed on both sides of the longitudinal movement block 16 are vertically slidably arranged with the longitudinal groove 20. After the transverse movement block 1 acts on the longitudinal movement block 16 to move in the vertical direction, it drives the insert 26 to protrude from the material strip 1000 and abut against both sides of the waste rib 01 of the material strip 1000.

[0040] like Figure 3 As shown, the lower end face of the longitudinal moving block 16 forms a third inclined surface 17. The third inclined surface is inclined from bottom to top towards the transverse moving block. Sliding blocks 30a are fixed on both sides of the longitudinal moving block 16 in a symmetrical arrangement with respect to the longitudinal moving block 16, so that the longitudinal moving block 16 can abut against the transverse moving block 1 through the third inclined surface 17. After the transverse moving block 1 acts on the longitudinal moving block 16, it can slide and connect with the longitudinal groove 20 in the vertical direction through the sliding blocks on both sides of the longitudinal moving block 16, so that the longitudinal moving block 16 can move in the vertical direction.

[0041] like Figure 2 and 3As shown in Figure 8, there are two longitudinal groove assemblies. The longitudinal groove assemblies are fixed to the lower mold 6 by two or more locking members. The distance between the longitudinal groove assemblies is greater than the width of the transverse block 1. The longitudinal groove assembly includes a third fixing block 18 and a third fixing seat 19 arranged perpendicularly to the third fixing block 18. A longitudinal groove 20 matching the slider is formed in the third fixing block 18. One end of the third fixing block 18 is fixedly connected to the third fixing seat 19 by a locking member. The third fixing seat 19 is fixedly connected to the lower mold 6 by a locking member. Since the longitudinal groove assembly is fixedly connected to the lower mold 6, the longitudinal block 16 can drive the slider to slide in the longitudinal groove 20. In this way, the slider is limited by the longitudinal groove 20, so that the longitudinal block 16 can move in the vertical direction.

[0042] like Figure 3 As shown, the longitudinal repositioning assembly is located at one end away from the transverse block 1. The longitudinal repositioning assembly includes a longitudinal telescopic rod 22, a longitudinal spring 21 sleeved on the outside of the longitudinal telescopic rod 22, a longitudinal limiting block 23, and a longitudinal fixing block 24. The longitudinal fixing block 24 is fixedly connected to the longitudinal block 16 to form an integral unit. One end of the longitudinal telescopic rod 22 is fixedly connected to the longitudinal limiting block 23 fixed on the longitudinal fixing frame 25 through a locking member. The longitudinal fixing frame 25 is fixedly connected to the lower mold 6. The other end of the longitudinal telescopic rod 22 is fixedly connected to the longitudinal fixing block 24 through a locking member. The longitudinal spring 21 is fixedly connected between the longitudinal limiting block 23 and the longitudinal fixing block 24, which enables the longitudinal reset assembly to be connected with the longitudinal block 16 to form a whole. Since the longitudinal limiting block 23 of the longitudinal reset assembly is fixedly connected to the lower mold 6 through the longitudinal fixing frame 25, the longitudinal block 16 will compress the longitudinal telescopic rod 22 and the longitudinal spring 21 during the sliding process of the longitudinal groove 20, and limit the vertical movement distance of the longitudinal block 16. At the same time, the longitudinal block 16 can be reset under the action of the longitudinal spring 21.

[0043] In this embodiment, the distance from the end face of the transverse block 1 near the longitudinal block 16 to the longitudinal fixing frame 25 is greater than the extension length of the transverse telescopic rod 12, so as to ensure that the transverse block 1 is not limited by the longitudinal fixing frame 25 during the transverse movement and thus cannot achieve a sufficient transverse movement distance; the height of the longitudinal groove 20 is greater than the extension distance of the longitudinal telescopic rod 22, so as to prevent the slider from disengaging from the longitudinal groove 20 during the vertical movement of the longitudinal block 16.

[0044] like Figure 2 and 8As shown, the insert 26 is fixed to the longitudinal moving block 16 by a locking member. The side of the insert 26 near the waste rib 01 of the strip is provided with a guide slope 27. In this way, when the insert 26 moves upward in the vertical direction, the guide slope 27 can play a guiding role, thereby better protruding the waste rib 01 of the strip and making the insert 26 abut against both sides of the waste rib 01 of the strip. After the upper die 100 and the lower die 6 close the mold to punch the strip 1000, the two sides of the waste rib 01 of the strip form the component 02.

[0045] The working principle of this utility model is as follows: When the upper and lower dies 6 are closed to punch the strip 1000, the movement of the upper die drives the drive mechanism to move downward, which in turn exerts a force on the transverse block 1, causing the transverse block 1 to move laterally along the transverse groove 9. The transverse block 1 then acts on the longitudinal block 16, causing the longitudinal block 16 to move vertically along the longitudinal groove 20. This causes the insert 26 to protrude from the waste rib 01 of the strip and abut against both sides of the strip 1000. During this process, after the transverse block 1 moves laterally a certain distance, the transverse resetting component limits the transverse block 1 to prevent it from continuing to move. The longitudinal movement is limited by the longitudinal movement reset component to prevent the longitudinal movement block 16 from moving further. This allows the insert 26 to be fixedly abutted against both sides of the waste rib 01 of the strip during the strip punching process, thereby effectively preventing the waste rib 01 and the strip 1000 from bending and deforming. After the punching is completed, the upper and lower dies 6 open, and the upper die no longer exerts force on the lower die. Under the action of the transverse movement reset component, the transverse movement block 1 is reset. At the same time, under the action of the longitudinal movement reset component, the longitudinal movement block 16 drives the insert 26 to reset, thus not affecting the conveying of the strip 1000 after the punching is completed.
