Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to a multi-head stamping equipment. Background Art

[0002] Stamping equipment refers to various equipment used in material stamping and plastic forming. Its working principle is based on the principle of pressure processing. The metal sheet is pressed against the die by the punch to generate high pressure to form the parts of the required shape.

[0003] The stamping equipment generally includes a workbench, a stamping mechanism arranged above the workbench, a transmission mechanism for driving the stamping head, and a control system for controlling the transmission mechanism. In order to perform stamping operations on different workpieces on a stamping equipment and reduce the time for replacing the punches, the stamping mechanism is provided with multiple stamping heads and an adjustment mechanism for adjusting the replacement of the stamping heads. The stamping heads are replaced according to the stamping situation, but when the equipment is stamping, the locating seat on the top of the workbench is also required to cooperate, and each group of stamping heads corresponds to its own locating seat. Therefore, when replacing the stamping head, the locating seat also needs to be replaced at the same time. The replacement of the stamping head and the locating seat prolongs the overall stamping time and affects work efficiency. Summary of the invention

[0004] In order to improve the stamping efficiency for different stamping situations, the present application provides a multi-head stamping equipment.

[0005] The multi-head stamping equipment provided in this application adopts the following technical solution: A multi-head punching device, comprising a punching workbench, a positioning mechanism and a punch mechanism, wherein the positioning mechanism comprises a positioning platform rotatably mounted on the punching workbench and multiple groups of positioning seats arranged on the positioning platform, the punch mechanism comprises a punch body, multiple groups of punch heads and an adjustment assembly for rotating and replacing the punch heads, the adjustment assembly comprises an adjustment drive, an adjustment seat rotatably mounted on the bottom of the punch body and an adjustment transmission member connecting the adjustment drive and the adjustment seat, and multiple groups of the punch heads are fixed to the adjustment seat; The stamping equipment also includes a linkage mechanism for connecting the adjustment component and the positioning platform, the linkage mechanism includes a first linkage gear, a first linkage shaft arranged on the first linkage gear, a first bevel gear group arranged on the first linkage gear, a second linkage shaft arranged perpendicular to the first linkage shaft, and a second bevel gear group arranged on the second linkage shaft, and the positioning platform is provided with a positioning linkage shaft cooperating with the second bevel gear.

[0006] By adopting the above technical scheme, the punching head can be rotated and replaced through the adjusting component, and the required punching head can be selected according to the punching situation. The adjusting component has a simple structure and high replacement efficiency. The linkage mechanism realizes the linkage of the adjusting seat and the positioning table. When the punching head on the adjusting seat is rotated and replaced, the positioning seat also rotates synchronously, so that when the punching mechanism switches to a different punching head, the positioning seat located below is also adapted to the punching head of the punching station. Compared with the prior art that needs to adjust the adjusting component and the positioning seat separately, the present application has the effect of improving the efficiency of replacing the punching head, and the linkage mechanism adopts a gear transmission method, which has the effect of stable transmission and high transmission accuracy.

[0007] Optionally, the adjusting transmission member includes an adjusting driving gear arranged on the output shaft of the adjusting driving member and an adjusting inner ring gear cooperating with the adjusting driving gear, and the adjusting seat is provided with an adjusting rotating hole cooperating with the punch mechanism for rotation, and the adjusting inner ring gear is arranged on the inner side wall of the adjusting rotating hole.

[0008] By adopting the above technical scheme, the structural composition of the adjusting transmission member is disclosed. When the punch head needs to be replaced, the adjusting drive member is started to rotate the adjusting drive gear, and the adjusting drive gear drives the adjusting inner ring gear to transmit. The adjusting inner ring gear rotates to rotate the punch head at the bottom. When the punch head moves to correspond to the positioning seat, it stops rotating. The above-mentioned adjusting transmission member has a simple structure and the transmission stability is relatively ideal.

[0009] Optionally, the adjustment seat is provided with an adjustment outer gear ring that cooperates with the first linkage gear transmission, the number of teeth and module of the adjustment outer gear ring are the same as the bevel gear in the second bevel gear that cooperates with the positioning linkage shaft, and the positioning seat and the adjustment seat achieve the same rotation speed through a linkage mechanism.

[0010] By adopting the above technical solution, the number of teeth and the module of the bevel gear in the outer ring gear and the second bevel gear that cooperates with the positioning linkage shaft are adjusted to be consistent, and the transmission ratio of the first linkage gear and the first bevel gear group is designed, so that when the adjustment seat rotates, the positioning seat is driven to rotate synchronously with the same speed, ensuring that the positioning seat is replaced at the same time as the punch head is replaced, further improving the replacement efficiency.

[0011] Optionally, it also includes a control component for controlling the cooperation between the first linkage shaft and the first bevel gear, the control component includes a control rod slidably arranged at the bottom of the first linkage shaft, a locking block arranged at the end of the control rod, and a first elastic member connected to the locking block, a control socket for inserting the control rod is opened at the bottom of the first linkage shaft, the inner wall of the control socket has a first through hole for the locking block to pass through, and the inner wall of the first bevel gear has a locking hole corresponding to the first through hole.

[0012] By adopting the above technical solution and the setting of the control component, the first linkage shaft and the first bevel gear have two states, unlocked and locked. When the control rod is located in the control socket and the first locking block is inserted into the locking hole, the first linkage shaft and the first bevel gear are in a locked state. At this time, when the adjusting seat rotates, the positioning table is driven to rotate synchronously through the linkage mechanism. When the control rod is disengaged from the control socket, the first linkage shaft and the first bevel gear are rotationally matched. At this time, when the adjusting seat rotates, it is self-rotating and will not drive the positioning table to rotate synchronously, so that different stamping operations can be performed on one product at the same time, further improving the adaptability of the stamping situation.

[0013] Optionally, the punch mechanism has three groups of punch heads, which are circumferentially spaced along the axis of the adjustment seat. The adjustment drive drives the punch mechanism to have three punching stations. The inner wall of the first bevel gear has three groups of locking holes, and the locking blocks correspond to the locking holes one by one.

[0014] By adopting the above technical scheme, the number of punching heads and the matching number of locking blocks and locking holes are specifically disclosed. When the adjusting component rotates the punching head, the control system has preset the adjusting seat to stop rotating only when the punching head and the positioning seat correspond, that is, the rotation angle of the adjusting component is 120 degrees or a multiple of 120 degrees. Through three groups of locking blocks and locking holes, the locking blocks can correspond to the locking holes when the adjusting seat is in any punch station, ensuring that the control component can always control the linkage control of the positioning platform and the positioning seat.

[0015] Optionally, the arc length of the locking hole is greater than that of the locking block, and an unlocking inclined surface is provided at one end of the locking hole, and the control rod is rotated, and when the locking block and the unlocking inclined surface are engaged, the control rod axially disengages from the control socket; The outer side of the control rod is provided with a mounting sleeve, the inner wall of the mounting sleeve is provided with an arc-shaped unlocking groove, the outer side of the control rod is provided with a reset driving block arranged in the arc-shaped unlocking groove, the inner wall of the arc-shaped unlocking groove is provided with a second elastic member abutting against the reset driving block, and the second elastic member is arranged circumferentially along the axis of the mounting sleeve.

[0016] By adopting the above technical solution, the arc length of the locking hole is greater than the locking block, so that the locking block can also rotate circumferentially along its axis in the locking hole. When the locking block and the unlocking inclined surface correspond to each other, the operator can pull the control rod out of the axis in the control socket to unlock the control rod. The unlocking operation is convenient. At the same time, under the action of the mounting sleeve, the reset drive block and the second elastic member, the control rod can be reset under the action of the second elastic member after being unlocked and disengaged, so as to facilitate the next locking. The abutment of the second elastic member against the reset drive block can also improve the stability of the locking block in the locked state.

[0017] Optionally, the top of the mounting sleeve fits with the bottom of the first bevel gear, a rotary bearing is provided on the top of the mounting sleeve, and the first bevel gear has a rotary groove for installing the rotary bearing.

[0018] By adopting the above technical solution, the mounting sleeve and the bottom of the first bevel gear fit together, so that the control rod is still in the mounting sleeve after it is separated from the control socket, which can reduce the probability of external dust entering the control socket and play a guiding role for the mounting hole to be inserted into the control socket next time. The cooperation of the rotating bearing and the rotating groove ensures that the mounting sleeve is in a stationary state when the first bevel gear rotates, thereby reducing the influence of the mounting sleeve on the control rod.

[0019] Optionally, the stamping workbench is also provided with a positioning drive member for driving the positioning linkage shaft to rotate and a lifting assembly for driving the positioning drive member to rise and fall, the lifting assembly includes a lifting seat for installing the positioning drive member and a lifting drive member, a connecting piece is provided at the bottom of the control rod, and the stamping work is provided with abutment notch at the bottom of the connecting piece corresponding to the bottom, and a metal clip for abutting the connecting piece is provided on the inner side wall of the abutment notch, and when the connecting piece is in the abutment notch and the connecting piece abuts the metal clip, the power supply of the lifting drive member is in a connected state.

[0020] By adopting the above technical solution and the setting of the positioning drive member and the lifting assembly, when the control lever is in the unlocked state, the positioning drive member is moved upward through the lifting assembly, and the positioning drive member and the second linkage shaft are connected to realize the independent rotation of the positioning platform without affecting the replacement of the punching head. The setting of the metal clip and the connecting piece can control the positioning drive member and reduce the occurrence of accidental rising of the positioning drive member.

[0021] Optionally, the stamping workbench is provided with an operating rod for driving the control rod to rise and fall, the operating rod is slidably installed on the stamping workbench, one end of the operating rod is provided with a matching hole running through both sides, the bottom of the control rod is provided with three groups of extension rods arranged at intervals, the ends of the extension rods are matched and plugged into the matching holes; a connecting rod for driving the control rod to rotate is also rotatably provided on the operating rod, the connecting rod is provided with a plug-in block, the operating rod is provided with a connecting hole connected to the matching hole, and the extension rod is provided with a plug-in hole for inserting the plug-in block.

[0022] By adopting the above technical solution, the setting of the operating rod makes it easy for the operator to lift and rotate the control rod, thereby improving the convenience of operation. In addition, the setting of the three groups of extension rods and matching holes ensures that the control rod and the operating rod are always in a matched plug-in state.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application realizes the linkage between the adjustment seat and the positioning table through the setting of the linkage mechanism. When the rotation on the adjustment seat is changed, the positioning seat also rotates synchronously. When the stamping mechanism switches to a different stamping head, the positioning seat located below also adapts to the stamping head of the stamping station, thereby improving the stamping efficiency; 2. The present application uses the setting of the control component to enable the first linkage shaft and the first bevel gear to have two sets of states: unlocked and locked, so that the adjustment seat and the positioning platform can rotate synchronously or independently; 3. The present application provides an operating lever to facilitate the operator to lift and rotate the control lever, thereby improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] The following is combined with Figure 1-10 This application is described in further detail.

[0037] The embodiment of the present application discloses a multi-head stamping device.

[0038] Reference Figure 1 A multi-head stamping equipment includes a stamping workbench 1, a positioning mechanism 2 for placing a workpiece, a punch mechanism 3 for stamping, and a linkage mechanism 4 connecting the positioning mechanism 2 and the punch mechanism 3.

[0039] Reference Figure 1 and Figure 2 The stamping workbench 1 has a working surface 11 for installing the positioning mechanism 2, and the working surface 11 corresponds to the punch mechanism 3. The positioning mechanism 2 includes a positioning table 21 rotatably mounted on the working surface 11 and a positioning seat 22 fixed to the top of the positioning table 21 and for placing the workpiece. The positioning seats 22 are arranged at intervals along the circumferential axis of the positioning table 21. An operation panel 12 is provided on one side of the stamping workbench 1, and the operation panel 12 is an interface for the control system to interact with the user.

[0040] The punch mechanism 3 includes a punch body 31, a plurality of punch heads 32 and an adjustment assembly 33 installed on the punching workbench 1. The opposite sides of the punch body 31 cooperate with the slide rails and grooves of the punching workbench 1. A punching drive 34 for driving the punch body 31 to rise and fall is provided on the top of the punching workbench 1. The punching drive 34 is a rotary motor, and its output shaft is fixed to the top of the punch body 31 through a reducer.

[0041] Reference Figure 2 and Figure 3 The adjustment assembly 33 includes an adjustment drive 331, an adjustment seat 332 rotatably mounted at the bottom of the punch body 31, and an adjustment transmission member 333. The adjustment seat 332 is an annular shell with an opening at the top. The axis of the adjustment seat 332 and the axis of the punch body 31 are arranged in a staggered manner, and there is an adjustment rotation hole inside the adjustment seat 332 for rotationally mounting with the punch mechanism 3. The adjustment drive 331 is a rotating motor, and its output shaft is vertically downward. The punch body 31 is provided with a motor support plate 311 for mounting the adjustment drive 331.

[0042] The adjusting transmission member 333 includes an adjusting driving gear 3331 coaxially fixed to the output shaft of the adjusting driving member 331 and an adjusting inner gear ring 3332 circumferentially uniformly arranged on the inner side wall of the adjusting seat 332. The adjusting inner gear ring 3332 is arranged on the inner side wall of the adjusting rotating hole. Among them, an adjusting clamping ring 334 for fixing the adjusting seat 332 is also arranged on the top of the adjusting seat 332. The inner side of the bottom surface of the adjusting clamping ring 334 is pressed against the punch body 31, and the outer side of the bottom is pressed against the adjusting seat 332. The adjusting clamping ring 334 and the adjusting seat 332 are fixedly connected by bolts. When the adjusting driving member 331 is started, the adjusting driving gear 3331 drives the adjusting inner gear ring 3332 to rotate, and drives the adjusting seat 332 and the adjusting clamping ring 334 to rotate synchronously.

[0043] The punching head 32 is fixed to the bottom of the adjustment seat 332. In this embodiment, three groups of punching heads 32 are installed at the bottom of the adjustment seat 332. The punching heads 32 are evenly spaced along the axis of the adjustment seat 332, and the axis of one group of punching heads 32 is coaxial with the axis of the punch body 31. The punching head 32 coaxial with the punch body 31 is used as the working punching head 32. Therefore, when the adjustment drive 331 drives the adjustment seat 332 to rotate, the three groups of punching heads 32 are coaxial with the punch body 31 in turn, so that the stamping mechanism has three stamping stations. Among them, the control system of the stamping equipment controls the adjustment drive 331 so that the angle of each rotation of the adjustment seat 332 is 120 degrees or a multiple of 120 degrees.

[0044] Reference Figure 3 and Figure 4 The linkage mechanism 4 is located on one side of the punch body 31, and includes a first linkage gear 41, a first linkage shaft 42, a first bevel gear set 43, a second linkage shaft 44, and a second bevel gear set 45. The punching table 1 has a linkage box 13 for arranging the linkage mechanism 4.

[0045] The first linkage gear 41 is arranged horizontally, and the outer side wall of the adjustment seat 332 has an adjustment outer gear ring 3321 meshing with the first linkage gear 41. The adjustment outer gear ring 3321 is not tightly meshed with the first linkage gear 41. The first linkage shaft 42 is arranged vertically and fixed coaxially with the first linkage gear 41, and a first mounting seat 131 for rotatably mounting the first linkage shaft 42 is provided in the linkage box 13.

[0046] The first bevel gear set 43 includes a first bevel gear 431 fixed to the first linkage shaft 42 and a second bevel gear 432 fixed to the second linkage shaft 44. The second linkage shaft 44 and the first linkage shaft 42 are perpendicular to each other, and the second bevel gear set 45 includes a third bevel gear 451 and a fourth bevel gear 452 fixed to the second linkage shaft 44. A positioning linkage shaft 46 for fixing and installing the fourth bevel gear 452 is fixed along the axis of the bottom of the positioning table 21, and the positioning linkage shaft 46 and the fourth bevel gear 452 are coaxially fixed. The linkage box 13 and the stamping workbench 1 respectively have a second mounting seat 14 for rotating and installing the two ends of the second linkage shaft 44.

[0047] When the adjustment seat 332 rotates, the positioning platform 21 is driven to rotate synchronously through the linkage mechanism 4. In order to ensure that the adjustment seat 332 and the positioning platform 21 rotate at the same speed, the transmission ratio of the outer gear ring 3321 to the driven gear of the second bevel gear set 45 (i.e., the fourth bevel gear 452) is 1. The number of teeth of the first bevel gear 431 is defined as Z1, the number of teeth of the second bevel gear 432 is defined as Z2, the number of teeth of the third bevel gear 451 is defined as Z3, the number of teeth of the fourth bevel gear 452 is defined as Z4, the number of teeth of the adjustment outer gear ring 3321 is defined as Z5, and the number of teeth of the first linkage gear 41 is defined as Z6. The number of teeth of the first linkage gear 41 is smaller than that of the adjustment outer gear ring 3321, and it is necessary to satisfy Z2*Z3=Z5*Z4 to meet the synchronous speed of the adjustment seat 332 and the positioning platform 21.

[0048] Reference Figure 4 and Figure 5 The present application further provides a control mechanism 5 for controlling the first linkage shaft 42 and the first bevel gear 431 at the bottom of the first linkage shaft 42. The control mechanism 5 includes a control rod 51 slidably mounted at the bottom of the first linkage shaft 42, a locking block 52 provided on the top side wall of the control rod 51, and a first elastic member 53 connected to the locking block 52.

[0049] The control rod 51 and the first linkage shaft 42 are coaxially arranged, and a control socket 421 for inserting the control rod 51 is provided at the bottom of the first linkage shaft 42. The control socket 421 extends upward to the inner hole of the first bevel gear 431, and the control rod 51 has a first through hole 422 on both inner and outer side walls of the control socket 421 for the locking block 52 to pass through. The inner wall of the first bevel gear 431 has a locking hole 4311 corresponding to the first through hole 422.

[0050] Reference Figure 5 and Figure 6 The side wall of the control rod 51 has a mounting groove 511 for mounting the locking block 52, and the extending direction of the mounting groove 511 is the radial direction of the cross section of the control rod 51. The first elastic member 53 is a spring member, one end of which is fixed to the bottom wall of the mounting groove 511, and the other end is fixed to the locking block 52. The locking block 52 has a locking portion protruding from the opening of the mounting groove 511 in the normal state of the first elastic member 53. In order to facilitate the insertion of the control rod 51 into the control socket 421, the top surface of the locking block 52 is also provided with a guiding inclined surface 521, and the guiding inclined surface 521 gradually extends upward from the end of the locking block 52 to the axis of the control rod 51.

[0051] When the control rod 51 is inserted into the control socket 421 from bottom to top, and after the locking block 52 and the locking hole 4311 are aligned, the locking block 52 is automatically inserted into the locking hole 4311 under the action of the first elastic member 53, and the first linkage shaft 42 and the first bevel gear 431 are fixedly connected through the control rod 51. At this time, the first linkage shaft 42 and the first bevel gear 431 are in a locked state. When the adjustment seat 332 rotates, the positioning platform 21 will be driven to rotate synchronously.

[0052] When the locking block 52 is not in the locking hole 4311, after the adjusting seat 332 rotates, the first linkage shaft 42 and the first bevel gear 431 are in rotational cooperation, and the first linkage shaft 42 rotates independently. In order to reduce the impact of the first linkage shaft 42 on the first bevel gear 431 when rotating, a rotating bearing 4312 is also installed in the inner hole of the first bevel gear 431 to abut against the side wall of the first linkage shaft 42.

[0053] In this embodiment, three sets of locking blocks 52 are installed on the control rod 51, and the first linkage shaft 42 and the first bevel gear 431 respectively have a first through hole 422 and a locking hole 4311 corresponding to the locking blocks 52. Since the rotation angle of the adjustment seat 332 is a multiple of 120 degrees, no matter how the first linkage shaft 42 rotates, after each adjustment, the locking block 52 always corresponds to the locking hole 4311.

[0054] The arc length of the locking hole 4311 and the first through hole 422 along the axis of the first bevel gear 431 is greater than the arc length of the locking block 52, so that the locking block 52 can rotate circumferentially along the axis of the control rod 51. The first bevel gear 431 is provided with an unlocking inclined surface 4313 at one end of the locking hole 4311, and the unlocking inclined surface 4313 extends to the control rod 51. The unlocking inclined surface 4313 and the inclined direction are opposite to the guide inclined surface 521, so that after the locking block 52 moves to the unlocking inclined surface 4313, the control rod 51 is moved downward, and the locking block 52 can be disengaged from the locking hole 4311 and the first through hole 422, thereby realizing the unlocking of the first linkage shaft 42 and the first bevel gear 431. Among them, the adjustment seat 332 has only one rotation direction, which is opposite to the rotation direction of the locking block 52 in the locking hole 4311, so that after the first linkage shaft 42 and the first bevel gear set 43 are locked, when the first linkage shaft 42 rotates, the locking block 52 will always abut against the side wall of the locking hole 4311 away from the unlocking inclined surface 4313.

[0055] Reference Figure 6 and Figure 7 The first linkage shaft 42 has a mounting sleeve 54 below which the guide control rod 51 is inserted, and the control rod 51 and the mounting sleeve 54 are coaxially slidably matched. The inner side wall of the mounting sleeve 54 is provided with an arc-shaped unlocking groove 541 along the circumferential direction, and the side wall of the control rod 51 is integrally provided with a reset driving block 512 located in the arc-shaped unlocking groove 541.

[0056] The arc length of the arc unlocking slot 541 is greater than that of the reset driving block 512, and the length of the arc unlocking slot 541 on the axis is greater than that of the reset driving block 512. The reset driving block 512 can rotate circumferentially in the arc unlocking slot 541, or slide axially in the arc unlocking slot 541.

[0057] The mounting sleeve 54 is provided with a plurality of groups of second elastic members 542 spaced apart along the axis thereof in the arc-shaped unlocking groove 541. The second elastic member 542 is a spring, which is arranged circumferentially along the axis of the mounting sleeve 54, that is, the second elastic member 542 is arranged in the arc-shaped unlocking groove 541 as a whole in the form of an arc-shaped strip. One end of the second elastic member 542 abuts against the inner wall of the arc-shaped unlocking groove 541, and the other end is connected to the reset driving block 512. A lifting block 5121 is slidably mounted on the reset driving block 512 toward one end of the second elastic member 542, and the lifting block 5121 slides along the axis of the mounting sleeve 54. The end of the second elastic member 542 is fixed to the lifting block 5121. In the normal state of the second elastic member 542, the locking block 52 is located at the end away from the unlocking inclined surface 4313. After the control rod 51 is rotated to disengage the locking block 52 from the unlocking inclined surface 4313 , the control rod 51 is reset circumferentially under the action of the second elastic member 542 , so that the locking block 52 is rotated again to the end away from the unlocking inclined surface 4313 .

[0058] The stamping workbench 1 has a fixing plate 15 for fixing the bottom of the mounting sleeve 54, the top surface of the mounting sleeve 54 is in contact with the bottom of the first bevel gear 431, and a rotating bearing 4312 is fixedly installed on the top of the mounting sleeve 54, and a rotating bearing 4312 for installing the rotating bearing 4312 is provided at the bottom of the first bevel gear 431, so that when the first bevel gear 431 rotates, the mounting sleeve 54 is in a relatively static state.
