Description

Technical Field

[0001] The invention belongs to the technical field of stamping, and in particular relates to an automatic feeding continuous stamping die. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts (or semi-finished products) during cold stamping. They are called cold stamping dies. There are many types of cold stamping dies, such as blanking dies, punching dies, cutting dies, notching dies, trimming dies, and cutting dies. Among them, blanking dies are used to separate materials along closed contours to form workpieces or process parts. Workpieces processed by blanking dies are usually flat and are usually continuously stamped.

[0003] Since the blanking die is stamped continuously, manual feeding will cause waste of materials and labor, and is also very dangerous, so an automatic feeding mechanism is usually required. However, the existing automatic feeding mechanism is usually set on the feeding side of the blanking die. The material on the feeding side has not been stamped and has a relatively smooth surface, which is easy to slip between the feeding wheel (or feeding roller), resulting in inaccurate feeding. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides an automated feeding continuous stamping die, which has the advantage of making the automated feeding more precise, and solves the problem in the prior art that the material on the feed side is not stamped, the surface is relatively smooth, and it is easy to slip between the feed wheel, thereby causing inaccurate feeding.

[0005] The present invention is achieved as follows: an automated feeding continuous stamping die comprises a first die base and a second die base aligned with each other, wherein the first die base and the second die base are respectively fixedly connected with a punch and a die on one side close to each other, and the punch and the die are respectively provided with a core and a cavity aligned with each other on one side close to each other, and two raw material strip limiting rollers are provided on the feeding side of the punch and the die; a feeding table is provided on the discharging side of the punch and the die, and a rotating driving member (for example, a motor) is provided on the feeding table, and a material tapping roller is fixedly connected to the output end of the rotating driving member, and an auxiliary roller parallel to the axial direction of the material tapping roller is provided on one side of the material tapping roller, and the outer peripheral surface of the material tapping roller has a first material tapping member that can extend into a waste strip residual hole (a hole generated after blanking), and the outer peripheral surface of the auxiliary roller has a second material tapping member that can extend into the waste strip residual hole, and the first material tapping member and the second material tapping member can fit together.

Similarly, the second material pushing member can be arranged in the same way as the first material pushing member.

Through this setting, the position of the annular material blocking member can be further fixed, and the reliability of material blocking can be improved.

[0011] Preferably in the present invention, the annular material blocking member includes an annular baffle and a third airbag, the inner ring of the annular baffle is sleeved on the first airbag, the third airbag is an annular airbag, fixedly sleeved on the outer edge of the annular baffle, and the third airbag extends into the second annular grooves.

[0012] Preferably in the present invention, a chute is formed on the side wall of the second die base close to the discharging side; a connecting plate is fixedly connected to one side of the feeding table close to the second die base, the connecting plate is inserted into the chute, and the connecting plate is fixedly connected to the second die base by bolts.

A liftable support plate is arranged in the receiving groove, the lower end of the support plate is in contact with the fourth airbag, the roller shaft of the material pushing roller is rotatably connected to the support plate, and the rotation driving member is fixedly connected to the support plate; further included is an air pump, one end of the air pump is communicated with the first airbag, the other end of the air pump is communicated with the fourth airbag, the air pump can inject the gas in the first airbag into the fourth airbag, and the air pump can inject the gas in the fourth airbag into the first airbag; two groups of support frames are fixedly connected to the feeding table, and the roller shaft of the auxiliary roller is rotatably connected to the support frames.

[0017] Since the first airbag is communicated with the fourth airbag and the first airbag is in a one-way rotation state, in order to avoid the hose connecting the first airbag and the fourth airbag from being wound, therefore, only one support plate is provided, and the other end of the material pushing roller is in a suspended state. The hose and the first airbag are connected through a rotary joint, so that the hose is not wound.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, during use, the raw material strip passes through two raw material strip limiting rollers and then feeds to the upper side of the female die. The hydraulic press drives the male die to move downward through the first die base, and the stamping of the workpiece is realized through the shearing of the core and the cavity, specifically blanking (a blanking hole communicated with the cavity is provided on the second die base). The waste strip left after blanking passes through the material pushing roller and the auxiliary roller. On the one hand, the material pushing roller and the auxiliary roller press the waste strip tightly, thereby realizing the automatic discharging of the waste strip. Since the waste strip and the raw material strip are integrated, therefore, the automatic feeding of the raw material strip can be realized.

[0021] 3. In the present invention, a shifting block is provided. The shifting block can be embedded into the holes left by the waste strips, and the distance between two adjacent first feeding members is the same as the distance between two adjacent holes left by the waste strips on the waste strip, so as to achieve more accurate feeding.

[0022] 4. By providing a supporting wheel in the present invention, the annular material blocking member can be supported, thereby reducing the inclination degree of the feeding roller and making the automatic feeding more stable. Moreover, if the supporting wheel is not provided, when the feeding roller descends, the third airbag in the annular material blocking member will be separated from the second annular groove. After the supporting wheel is provided, when the feeding roller descends, the supporting wheel presses the third airbag, so that the third airbag expands, and the third airbag can still be located in the second annular groove.

[0032] In order to further understand the content, characteristics and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0033] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Please refer to Figures 1-4 , an automatic feeding continuous stamping die provided by an embodiment of the present invention includes a first die holder 1 and a second die holder 2 that are aligned with each other. On the sides of the first die holder 1 and the second die holder 2 that are close to each other, a punch 3 and a die 4 are respectively fixedly connected. On the sides of the punch 3 and the die 4 that are close to each other, a core 5 and a cavity 6 that are aligned with each other are respectively provided. On the feeding sides of the punch 3 and the die 4, two raw material strip limiting rollers 7 are provided; on the discharging sides of the punch 3 and the die 4, a feeding table 8 is provided. A rotating driving part 9 (such as a motor) is provided on the feeding table 8. The output end of the rotating driving part 9 is fixedly connected with a material pushing roller 10. On one side of the material pushing roller 10, an auxiliary roller 11 that is axially parallel to the material pushing roller 10 is provided. On the outer peripheral surface of the material pushing roller 10, there is a first material pushing part 12 that can extend into the waste strip remaining hole (the hole generated after blanking). On the outer peripheral surface of the auxiliary roller 11, there is a second material pushing part 13 that can extend into the waste strip remaining hole. The first material pushing part 12 and the second material pushing part 13 can be attached to each other.

[0035] In use, the raw material strip passes through two raw material strip limiting rollers 7 and then feeds into the upper side of the female die 4. The hydraulic press drives the male die 3 to move downward through the first die base 1, and the stamping of the workpiece is realized through the shearing of the core 5 and the cavity 6. Specifically, blanking is performed (a blanking hole communicating with the cavity 6 is provided on the second die base 2), and the stamped workpiece falls from the blanking hole. The remaining waste strip after the workpiece falls is collected after passing through the material separating roller 10 and the auxiliary roller 11. On the one hand, the material separating roller 10 and the auxiliary roller 11 press the waste strip, thereby realizing the automatic discharging of the waste strip. Since the waste strip and the raw material strip are integrated, the automatic feeding of the raw material strip can be realized. Through this setting, when feeding the material, the first material separating member 12 and the second material separating member 13 can extend into the waste strip remaining hole [the hole generated after the workpiece is stamped off from the raw material strip, and has the same shape as the workpiece], thereby preventing slipping during material separation, and further making the automatic feeding more accurate.

[0036] Please refer to Figures 2-4 As shown in, the first material separating member 12 includes a first airbag 121 and two annular material retaining members 122. The first airbag 121 is an annular airbag and is elastic. The inner ring of the first airbag 121 is fixedly sleeved on the material separating roller 10; both of the two annular material retaining members 122 are sleeved on the first airbag 121.

[0037] The annular material retaining members 122 are used to block both sides of the waste strip, thereby limiting the waste strip. Through this setting, the following effects are achieved: First, the force of pressing the waste strip can be changed after the first airbag 121 expands; Second, after the first airbag 121 expands or contracts, it can be applied to the automatic feeding of materials with different thicknesses; Third, when the angular velocity of the material separating roller 10 remains unchanged, by changing the diameter of the first airbag 121, the feeding speed can be changed; Fourth, after the airbag expands, the working position of the annular material retaining member 122 can be fixed.

[0038] Please refer to Figure 4 As shown in, the first material separating member 12 further includes a plurality of material separating blocks 123. The material separating blocks 123 are fixedly connected to the outer surface of the first airbag 121 and are arranged annularly and equidistantly relative to the axis of the material separating roller 10. The shape of the first material separating member 12 is the same as the shape of the waste strip remaining hole, so that the material separating blocks 123 can be embedded into the waste strip remaining hole, and the distance between adjacent two first material separating members 12 is the same as the distance between adjacent two remaining holes on the waste strip, thereby enabling more accurate material separation. Similarly, the second material separating member 13 can be set in the same way as the first material separating member 12.

[0039] Since the first airbag 121 is elastic, the expansion or contraction of the first airbag 121 can change the distance between the material separating blocks 123, thereby being applicable to the situation where the remaining holes on the waste strip are different. For raw material strips with different thicknesses and different materials, the processing distances are all different.

[0040] Please refer toFigure 4 The outer ring of the first airbag 121 is provided with a number of equally spaced first annular grooves 124, and the inner rings of the two annular baffle members 122 are both clamped in the first annular grooves 124.

[0041] Through this setting, the working position of the annular baffle member 122 can be fixed more firmly. Thus, after the first airbag 121 deflates, the position of the annular baffle member 122 can be adjusted, and the annular baffle member 122 can be fixed again after inflation.

[0042] Please refer to Figure 4 The second material pushing member 13 includes a second airbag 131. The second airbag 131 is an annular airbag. The inner ring of the second airbag 131 is fixedly sleeved on the auxiliary roller 11. The outer ring of the second airbag 131 is provided with a number of equally spaced second annular grooves 132. The second annular grooves 132 are aligned with the first annular grooves 124, and the outer ring of the annular baffle member 122 can extend into the second annular grooves 132. Through this setting, the position of the annular baffle member 122 can be further fixed, and the reliability of material baffle can be improved.

[0043] Please refer to Figure 4 The annular baffle member 122 includes an annular baffle 1221 and a third airbag 1222. The inner ring of the annular baffle 1221 is sleeved on the first airbag 121. The third airbag 1222 is an annular airbag and is fixedly sleeved on the outer edge of the annular baffle 1221. The third airbag 1222 extends into the second annular grooves 132.

[0044] Through this setting, on the one hand, it has a buffering effect. On the other hand, by inflating or deflating the third airbag 1222, the outer diameter of the annular baffle member 122 can be adjusted.

[0045] Please refer to Figure 1 A chute 14 is formed in the side wall of the second die base 2 close to the discharging side; a connecting plate 15 is fixedly connected to one side of the feeding table 8 close to the second die base 2. The connecting plate 15 is inserted into the chute 14, and the connecting plate 15 is fixedly connected to the second die base 2 by bolts.

[0046] Please refer to Figure 1, two first guide posts 16 are fixedly connected to the discharging side of the second die base 2, a first guide sleeve 17 is fixedly connected to the first die base 1, and the first guide posts 16 are slidably inserted into the first guide sleeve 17; two second guide posts 18 are fixedly connected to the feeding side of the second die base 2, a second guide sleeve 19 is fixedly connected to the first die base 1, and the second guide posts 18 are slidably inserted into the second guide sleeve 19; two raw material strip limiting rollers 7 are rotatably connected to the second guide posts 18. Through this setting, the second guide posts 18 can carry the raw material strip limiting rollers 7, and the raw material strip limiting rollers 7 can also limit the second guide posts 18 to prevent the second guide posts 18 from tilting. It should be noted that the height of the raw material strip limiting rollers 7 should not interfere with the mold closing.

[0047] Please refer to Figure 4 , Figures 6-8 , on one side of the upper surface of the feeding table 8, there is a receiving groove 20, in the receiving groove 20 there is a fourth airbag 21, in the receiving groove 20 there is a liftable support plate 22, the lower end of the support plate 22 is in contact with the fourth airbag 21, the roller shaft of the material pushing roller 10 is rotatably connected to the support plate 22, and the rotation driving member 9 is fixedly connected to the support plate 22; further included is an air pump 23, one end of the air pump 23 is communicated with the first airbag 121, the other end of the air pump 23 is communicated with the fourth airbag 21, the air pump 23 can inject the gas in the first airbag 121 into the fourth airbag 21, and the air pump 23 can inject the gas in the fourth airbag 21 into the first airbag 121; two groups of support frames 24 are fixedly connected to the feeding table 8, and the roller shaft of the auxiliary roller 11 is rotatably connected to the support frames 24. For example, the roller shaft of the auxiliary roller 11 is rotatably connected to the support frames 24 through bearings.

[0048] During use, if the support plate 22 is fixedly connected to the feeding table 8, when the first airbag 121 expands, the height of the upper surface of the first airbag 121 increases, and at this time, the waste strip will be lifted up, causing the waste strip not to fit with the female die 4, thus affecting the stamping quality. In this application, by setting the fourth airbag 21, when the first airbag 121 is inflated, the gas in the fourth airbag 21 decreases, and the support plate 22 descends accordingly, so that the height of the upper surface of the first airbag 121 remains unchanged. And because the roller shaft of the material pushing roller 10 is rotatably connected to the support plate 22, the material pushing roller 10 and the support plate 22 rise and fall synchronously and are always perpendicular. Therefore, when the first airbag 121 expands, by lowering the material pushing roller 10, the distance between the first airbag 121 and the second airbag 131 can also be ensured.

[0049] Please refer to Figure 4 and Figure 5, a slideway 25 is provided on the feeding table 8, a slider 26 is provided in the slideway 25, a supporting wheel 27 is provided on the slider 26, a third annular groove 28 is provided on the outer peripheral surface of the supporting wheel 27, and the edge of the annular material retaining member 122 is clamped in the third annular groove 28.

[0050] Since the first airbag 121 and the fourth airbag 21 are communicated, and the first airbag 121 is in a one-way rotation state, in order to avoid the hose connecting the first airbag 121 and the fourth airbag 21 from being wound, therefore, only one support plate 22 is provided, the other end of the material shifting roller 10 is in a suspended state, and the hose and the first airbag 121 are connected through a rotary joint, so that the hose is not wound.

[0051] In this application, by providing the supporting wheel 27, the annular material retaining member 122 can be supported, thereby reducing the inclination degree of the material shifting roller 10 and making the automatic feeding more stable. Moreover, if the supporting wheel 27 is not provided, when the material shifting roller 10 descends, the third airbag 1222 in the annular material retaining member 122 is separated from the second annular groove 132. After the supporting wheel 27 is provided, when the material shifting roller 10 descends, the supporting wheel 27 squeezes the third airbag 1222, so that the third airbag 1222 expands, and the third airbag 1222 can still be located in the second annular groove 132.

[0052] The working principle of the present invention:

[0053] During use, the raw material strip passes through two raw material strip limiting rollers 7 and then feeds to the upper side of the female die 4. The hydraulic press drives the male die 3 to move downward through the first die holder 1, and the stamping of the workpiece is realized by the shearing of the core 5 and the cavity 6, specifically blanking (a blanking hole communicated with the cavity 6 is provided on the second die holder 2). The waste strip left after blanking passes through the material shifting roller 10 and the auxiliary roller 11. On the one hand, the material shifting roller 10 and the auxiliary roller 11 press the waste strip tightly, thereby realizing the automatic discharging of the waste strip. Since the waste strip and the raw material strip are integrated, the automatic feeding of the raw material strip can be realized. Through this setting, when shifting the material, the first material shifting member 12 and the second material shifting member 13 can extend into the waste strip leaving hole, thereby preventing slipping during material shifting and making the automatic feeding more accurate.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to this process, method, article or device.
