Description

Technical Field

[0001] The present invention relates to the technical field of machining manufacturing, and particularly relates to a workpiece drawing and cutting method. Background Art

[0002] A cold stamping die is a special process equipment for machining metal or non-metal materials into parts or semi-finished products during cold stamping processing. Due to processing requirements, some cold stamping dies are provided with a side cutting structure. In the prior art, when performing side cutting on a workpiece, most of them punch from the outside of the product to the inside of the product, and the burr direction of the side cut is also from the outside to the inside.

[0003] However, due to different production requirements of some workpieces, the burr direction of the side cut needs to be from the inside to the outside. To achieve the above side cutting effect, first, the traveling direction of the side cutting edge needs to be reversed so that it moves from the inside of the workpiece to the outside. Second, the product needs to be fixed before the side cutting of the edge to ensure its accuracy.

[0004] However, after the existing side cutting structures for performing side cutting on workpieces from the inside to the outside are actually applied by those skilled in the art, it is found that there are still some disadvantages. The more obvious one is that the processing process is relatively cumbersome and the degree of automation is low. Manual operations are required for both loading and unloading, which not only wastes manpower but also has a great impact on the side cutting processing efficiency of workpieces, and it cannot be effectively applied to the industrial side cutting processing operation of batch workpieces.

[0005] Therefore, it is very necessary to invent a workpiece drawing and cutting method to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a workpiece drawing and cutting method to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A workpiece drawing and cutting method, which is realized by a workpiece drawing and cutting device. The workpiece drawing and cutting device includes a workpiece conveyor belt, a machine case is arranged outside the workpiece conveyor belt, a driving mechanism is fixedly arranged at the bottom inside the machine case, a positioning and collecting mechanism is fixedly arranged at the top of the driving mechanism, a side cutting mechanism is fixedly arranged at the top inside the machine case, and trigger and blocking mechanisms are arranged on both sides at the bottom of the side cutting mechanism;

[0008] The driving mechanism includes a bottom plate, a driving shaft, a driving motor, a negative pressure collecting pipe, an outer sleeve pipe, a first spring, an inner sleeve pipe, an outer plate, and a trigger rod;

[0009] The bottom plate is fixedly arranged at the inner bottom of the chassis. The driving shaft penetrates through the bottom plate and is rotatably connected to the bottom plate through a bearing. The driving motor is fixedly arranged at the bottom of the bottom plate and is in transmission connection with the driving shaft. The negative pressure collecting pipe is connected to the bottom end of the driving shaft through a rotary joint. The outer sleeve, the first spring and the inner sleeve are sleeved on the outer side of the driving shaft in sequence from bottom to top. The outer sleeve is in transmission connection with the driving shaft through a reciprocating thread. The inner sleeve is slidably arranged inside the outer sleeve. The outer sleeve plate is fixedly sleeved on the top of the outer sleeve. There are two trigger rods, and the two trigger rods are respectively fixedly arranged on both sides of the top of the outer sleeve plate.

[0010] Preferably, the positioning and collecting mechanism includes a supporting column, a collecting table, a sealing column, positioning holes and collecting grooves.

[0011] Preferably, the supporting column is fixedly arranged at the top end of the inner sleeve. The driving shaft extends into the supporting column. The collecting table is fixedly sleeved on the outer bottom of the supporting column. The sealing column is fixedly arranged in the supporting column and is slidably arranged inside the driving shaft. There are two positioning holes and two collecting grooves. The two positioning holes are respectively opened on both sides of the top of the supporting column. The two collecting grooves are respectively opened on both sides of the supporting column.

[0012] Preferably, the side cutting mechanism includes a top plate, a limiting column, side plates, sliding plates and cutting knives.

[0013] Preferably, the top plate is fixedly arranged at the inner top of the chassis. The limiting column is fixedly arranged at the center of the bottom of the top plate. There are two side plates, two sliding plates and two cutting knives. The two side plates are respectively fixedly arranged on both sides of the bottom of the top plate. The two sliding plates respectively penetrate through the inner sides of the two side plates in a sliding manner. The two cutting knives are respectively fixedly arranged at one ends of the bottoms of the two sliding plates close to each other.

[0014] Preferably, the trigger and blocking mechanism includes a trigger block, a trigger groove, a blocking groove and a second spring.

[0015] Preferably, the trigger block is fixedly arranged at the bottom of the sliding plate. The trigger groove is opened at the bottom of the trigger block. The blocking groove is opened inside the trigger block. The cutting knife is located inside the blocking groove. One end of the second spring is fixedly connected to the side plate and the other end is fixedly connected to the trigger block.

[0016] Preferably, the workpiece pulling and cutting method specifically includes the following steps:

[0017] S1. Start the driving motor. After the driving motor is started, it drives the driving shaft to continuously rotate. When the driving shaft rotates, it drives the outer sleeve to rise. When the outer sleeve rises, it drives the supporting column to rise through the first spring and the inner sleeve. When the supporting column rises, it drives the sealing column to rise synchronously. When the rising distance of the outer sleeve reaches the first threshold, the top of the supporting column fits against the bottom of the workpiece directly above the supporting column.

[0018] S2. When the subsequent outer sleeve continues to rise, the supporting column drives the workpiece to rise synchronously. When the rising distance of the outer sleeve reaches the second threshold, the sealing column is withdrawn from the inner side of the driving shaft. At this time, the negative pressure inside the negative pressure collecting pipe is transmitted to the inside of the supporting column through the bottom plate, and then is respectively transmitted to the positioning hole and the collecting groove. The negative pressure inside the positioning hole adsorbs and positions the workpiece.

[0019] S3. When the rising distance of the outer sleeve reaches the third threshold, the workpiece is sleeved outside the limiting column and the two cutting knives driven by the supporting column. At the same time, the collecting table enters the inside of the two blocking grooves. At this time, the workpiece reaches the side cutting station and is fixed by the supporting column and the limiting column, and cannot continue to rise.

[0020] S4. Since the workpiece cannot continue to rise, at this time, as the outer sleeve continues to rise, the inner sleeve remains stationary and the first spring is continuously compressed. At the same time, the outer sleeve plate and the trigger rod continue to rise driven by the outer sleeve. When the rising distance of the outer sleeve reaches the fourth threshold, the trigger rod enters the inside of the trigger groove and fits with the inner wall of the trigger groove.

[0021] S5. At this time, as the outer sleeve continues to rise, the trigger rod pushes the trigger block through the trigger groove, and the trigger block drives the cutting knife to move outwards through the sliding plate. During the outward movement of the cutting knife, the workpiece is side-cut from the inside out. The chips generated during the side-cutting fall on the top of the collecting table under the restriction of the inner wall of the blocking groove, and then enter the inside of the supporting column through the collecting groove under the action of negative pressure, and are finally output and collected through the driving shaft and the negative pressure collecting pipe.

[0022] S6. When the rising distance of the outer sleeve reaches the fifth threshold, the side-cutting of the workpiece is completed. At the same time, the outer sleeve moves to the top of the reciprocating thread outside the driving shaft. Subsequently, as the driving shaft continues to rotate, the outer sleeve drives the workpiece to move down and reset, so that the side-cut workpiece falls on the top of the workpiece conveyor belt and is output. During the output process of this workpiece, the subsequent workpiece to be processed moves above the supporting column again.

[0023] The technical effects and advantages of the present invention:

[0024] The present invention is provided with a driving mechanism, a positioning and collecting mechanism, a side cutting mechanism and a triggering and blocking mechanism, so as to drive the positioning and collecting mechanism by means of the driving mechanism, and then the driving mechanism lifts the workpiece on the top of the workpiece conveyor belt to the side cutting station through the positioning and collecting mechanism. During the lifting process, the positioning and collecting mechanism triggers the driving mechanism to realize the positioning of the workpiece, and at the same time, the positioning and collecting mechanism enters the inner sides of the two triggering and blocking mechanisms, which is convenient for subsequent collection of side cutting chips. When the workpiece reaches the side cutting station, the driving mechanism stops driving the positioning and collecting mechanism, and at the same time triggers the triggering and blocking mechanism, so that the triggering and blocking mechanism drives the side cutting mechanism to realize the side cutting operation of the workpiece. Compared with the same type of devices in the prior art, the present invention is convenient to operate and has a high degree of automation, saving manpower while effectively improving the side cutting processing efficiency of the workpiece, and is more suitable for the industrial side cutting processing operation of batch workpieces.

Detailed Embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] The present invention provides a workpiece pulling and cutting method as shown in Figures 1-4 The workpiece pulling and cutting method is implemented by a workpiece pulling and cutting device. The workpiece pulling and cutting device includes a workpiece conveyor belt 1. A machine case 2 is arranged outside the workpiece conveyor belt 1. A driving mechanism 3 is fixedly arranged at the bottom inside the machine case 2. A positioning and collecting mechanism 4 is fixedly arranged at the top of the driving mechanism 3. A side cutting mechanism 5 is fixedly arranged at the top inside the machine case 2. Trigger blocking mechanisms 6 are arranged on both sides at the bottom of the side cutting mechanism 5.

[0033] As shown in Figure 2 The driving mechanism 3 includes a bottom plate 31, a driving shaft 32, a driving motor 33, a negative pressure collecting pipe 34, an outer sleeve pipe 35, a first spring 36, an inner sleeve pipe 37, an outer plate 38 and a trigger rod 39. Among them, the bottom plate 31 is fixedly arranged at the bottom inside the machine case 2. The driving shaft 32 penetrates the bottom plate 31 and is rotationally connected to the bottom plate 31 through a bearing. The driving motor 33 is fixedly arranged at the bottom of the bottom plate 31 and is in transmission connection with the driving shaft 32. The negative pressure collecting pipe 34 is connected to the bottom end of the driving shaft 32 through a rotary joint. The outer sleeve pipe 35, the first spring 36 and the inner sleeve pipe 37 are sleeved on the outside of the driving shaft 32 in sequence from bottom to top. The outer sleeve pipe 35 is in reciprocating screw transmission connection with the driving shaft 32. The inner sleeve pipe 37 is slidably arranged inside the outer sleeve pipe 35. The outer plate 38 is fixedly sleeved on the top outside the outer sleeve pipe 35. There are two trigger rods 39, and the two trigger rods 39 are respectively fixedly arranged on both sides at the top of the outer plate 38.

[0034] By arranging the above structure, after the driving motor 33 is started, it drives the driving shaft 32 to continuously rotate. When the driving shaft 32 rotates, it drives the outer sleeve pipe 35 to rise. When the outer sleeve pipe 35 rises, it drives the inner sleeve pipe 37 to rise through the first spring 36. When the inner sleeve pipe 37 cannot continue to rise subsequently, as the outer sleeve pipe 35 continues to rise, the inner sleeve pipe 37 remains stationary and the first spring 36 is continuously compressed. At the same time, the outer plate 38 and the trigger rod 39 continue to rise under the drive of the outer sleeve pipe 35.

[0035] As shown in Figure 3 The positioning and collecting mechanism 4 includes a supporting column 41, a collecting table 42, a sealing column 43, positioning holes 44 and collecting grooves 45. Among them, the supporting column 41 is fixedly arranged at the top of the inner sleeve pipe 37. The driving shaft 32 extends into the supporting column 41. The collecting table 42 is fixedly sleeved on the bottom outside the supporting column 41. The sealing column 43 is fixedly arranged inside the supporting column 41 and is slidably arranged inside the driving shaft 32. There are two positioning holes 44 and two collecting grooves 45 respectively. The two positioning holes 44 are respectively opened on both sides at the top of the supporting column 41. The two collecting grooves 45 are respectively opened on both sides of the supporting column 41.

[0036] By setting the above-mentioned driving mechanism 3 and positioning and collecting mechanism 4, when the supporting column 41 rises, it drives the sealing column 43 to rise synchronously until the top of the supporting column 41 fits against the bottom of the workpiece located directly above the supporting column 41. When the outer sleeve 35 continues to rise subsequently, the supporting column 41 drives the workpiece to rise synchronously. After the sealing column 43 is withdrawn from the inside of the driving shaft 32, the negative pressure inside the negative pressure collecting pipe 34 is transmitted to the inside of the supporting column 41 through the bottom plate 31, and then is respectively transmitted to the inside of the positioning hole 44 and the collecting groove 45. The negative pressure inside the positioning hole 44 adsorbs and positions the workpiece.

[0037] As Figure 4 shown, the side cutting mechanism 5 includes a top plate 51, a limiting column 52, side plates 53, a sliding plate 54 and a cutting tool 55. Among them, the top plate 51 is fixedly arranged at the inner top of the chassis 2, the limiting column 52 is fixedly arranged at the center of the bottom of the top plate 51, there are two side plates 53, two sliding plates 54 and two cutting tools 55. The two side plates 53 are respectively fixedly arranged on both sides of the bottom of the top plate 51, the two sliding plates 54 respectively penetrate through the inside of the two side plates 53 in a sliding manner, and the two cutting tools 55 are respectively fixedly arranged at one end of the bottom of the two sliding plates 54 close to each other.

[0038] By setting the above structure, when the workpiece is sleeved outside the limiting column 52 and the two cutting tools 55 driven by the supporting column 41, the workpiece reaches the side cutting station and is fixed by the supporting column 41 and the limiting column 52, and at the same time, it cannot continue to rise.

[0039] As Figure 4 shown, the trigger and blocking mechanism 6 includes a trigger block 61, a trigger groove 62, a blocking groove 63 and a second spring 64. Among them, the trigger block 61 is fixedly arranged at the bottom of the sliding plate 54, the trigger groove 62 is opened at the bottom of the trigger block 61, the blocking groove 63 is opened inside the trigger block 61, the cutting tool 55 is located inside the blocking groove 63, and one end of the second spring 64 is fixedly connected to the side plate 53 and the other end is fixedly connected to the trigger block 61.

[0040] By setting the above structure, when the collecting table 42 enters the inside of the blocking groove 63, the two side walls of the blocking groove 63 can respectively block the side cutting chips from the front and back sides of the collecting table 42, thereby avoiding the scattering of the side cutting chips. At the same time, when the trigger rod 39 pushes the trigger block 61 through the trigger groove 62, the trigger block 61 compresses the second spring 64, and at the same time drives the cutting tool 55 to move outwards through the sliding plate 54. During the outward movement of the cutting tool 55, the workpiece is side cut from the inside to the outside, and the chips generated during the side cutting fall on the top of the collecting table 42 under the restriction of the inner wall of the blocking groove 63.

[0041] Embodiment 2

[0042] The specific steps of the workpiece pulling and cutting method are as follows:

[0043] S1. Start the driving motor 33. After the driving motor 33 starts, it drives the driving shaft 32 to rotate continuously. When the driving shaft 32 rotates, it drives the outer sleeve 35 to rise. When the outer sleeve 35 rises, it drives the supporting column 41 to rise through the first spring 36 and the inner sleeve 37. When the supporting column 41 rises, it drives the sealing column 43 to rise synchronously. When the rising distance of the outer sleeve 35 reaches the first threshold, the top of the supporting column 41 fits against the bottom of the workpiece located directly above the supporting column 41.

[0044] S2. When the outer sleeve 35 continues to rise subsequently, the supporting column 41 drives the workpiece to rise synchronously. When the rising distance of the outer sleeve 35 reaches the second threshold, the sealing column 43 is withdrawn from the inside of the driving shaft 32. At this time, the negative pressure inside the negative pressure collecting pipe 34 is transmitted to the inside of the supporting column 41 through the bottom plate 31, and then is respectively transmitted to the inside of the positioning hole 44 and the collecting groove 45. The negative pressure inside the positioning hole 44 adsorbs and positions the workpiece.

[0045] S3. When the rising distance of the outer sleeve 35 reaches the third threshold, the workpiece is sleeved outside the limiting column 52 and the two cutting tools 55 under the drive of the supporting column 41. At the same time, the collecting table 42 enters the inside of the two blocking grooves 63. At this time, the workpiece reaches the side cutting station and is fixed by the supporting column 41 and the limiting column 52, and cannot continue to rise.

[0046] S4. Since the workpiece cannot continue to rise, at this time, as the outer sleeve 35 continues to rise, the inner sleeve 37 remains stationary and the first spring 36 is continuously compressed. At the same time, the outer sleeve plate 38 and the trigger rod 39 continue to rise under the drive of the outer sleeve 35. When the rising distance of the outer sleeve 35 reaches the fourth threshold, the trigger rod 39 enters the inside of the trigger groove 62 and fits against the inner wall of the trigger groove 62.

[0047] S5. At this time, as the outer sleeve 35 continues to rise, the trigger rod 39 pushes the trigger block 61 through the trigger groove 62. The trigger block 61 drives the cutting tool 55 to move outwards through the sliding plate 54. During the outward movement of the cutting tool 55, the workpiece is cut from the inside to the outside. The debris generated during the side cutting process is restricted by the inner wall of the blocking groove 63 and falls on the top of the collecting table 42, and then enters the inside of the supporting column 41 under the action of negative pressure, and finally is output and collected through the driving shaft 32 and the negative pressure collecting pipe 34. [[ID=]

[17] ]

[0048] S6. When the rising distance of the outer sleeve 35 reaches the fifth threshold, the side cutting of the workpiece is completed. At the same time, the outer sleeve 35 moves to the top of the reciprocating thread outside the driving shaft 32. Subsequently, as the driving shaft 32 continues to rotate, the outer sleeve 35 drives the workpiece to move down and reset, so that the workpiece after side cutting falls on the top of the workpiece conveyor belt 1 and is output. During the output process of this workpiece, the subsequent workpiece to be processed moves above the supporting column 41 again.

[0049] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
