Description

Technical Field

[0001] This invention belongs to the field of sealing strip cutting technology, and specifically relates to a trolley for rotatable sealing strip products and its working method. Background Technology

[0002] The sealing strip needs to be cut by a punching device during the cutting process. In the past, the strip loading trolley was arranged in a double-sided arrangement to correspond to the double chamber of the punching fixture. However, each double-sided double-chamber punching fixture is equipped with a separate cylinder or hydraulic cylinder as the punching power, which has a high manufacturing cost.

[0003] When using a single-sided multi-cavity tooling with multiple single-sided cavities arranged in a compact manner to reduce manufacturing costs, the original strip-loading carriage can no longer meet the production requirements for multi-angle punching. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the purpose of this invention is to provide a trolley for rotatable sealing strip products. Its structure is reasonably designed. The strip loading trolley adopts a single-sided placement form. The strip loading module of the trolley is driven to rotate to any angle by the trolley pressing strip rotation drive mechanism, so as to overcome the limitation of the punching direction caused by the single-sided multi-cavity tooling centralized configuration of the hydraulic cylinder, and effectively improve the stability and convenience during impact.

[0005] Technical solution: To achieve the above objectives, the present invention provides a trolley for a rotatable sealing strip product, comprising:

[0006] At least one sealing strip trolley, the sealing strip trolley including a trolley rotation conveying mechanism and a trolley pressing strip rotation drive mechanism, the trolley pressing strip rotation drive mechanism being located above the trolley rotation conveying mechanism, and the two cooperating with each other;

[0007] A lifting drive mechanism is included, with its output end connected to a fixed connecting plate, which in turn is connected to a trolley pressure strip rotation drive mechanism. The trolley for a rotatable sealing strip product described in this invention has a reasonable structural design. The trolley is positioned on one side, and the pressure strip rotation drive mechanism rotates the trolley's loading module to any angle. This overcomes the limitations on the punching direction imposed by the centralized configuration of the hydraulic cylinder with multiple cavities on one side, effectively improving stability and convenience during impact.

[0008] The trolley rotating conveying mechanism includes a set of lower track wall plates, a timing belt connector, a set of lower connecting rods, a set of semi-circular gears, a set of planar guide wheels and a set of inclined guide wheels. The lower track wall plates are arranged opposite to each other, and the lower part of the two lower track wall plates is connected by a timing belt connector, and the upper part is connected by a set of lower support columns.

[0009] The upper part of the inner side of the lower track wall panel is provided with a lower semi-circular track, the two ends of the lower connecting rod are provided with rollers, the rollers are located in the corresponding lower semi-circular track, the mounting bar semi-circular gear is provided on the lower connecting rod, and the two ends of the lower connecting rod located in the middle are provided with a set of reference position limiting blocks.

[0010] The planar guide wheel is located at the lower part of the lower track wall plate, and the inclined guide wheel is located above the planar guide wheel and installed on the inclined surface of the synchronous belt connector.

[0011] Furthermore, the synchronous belt connector is provided with a gear limiting block, and the gear limiting block is provided with a groove, which cooperates with the lower mounting bar semi-circular gear.

[0012] In addition, a set of reference positioning components is included. One side of the reference positioning component is fixed to the inner wall of the lower track wall panel, and it cooperates with the reference position limiting block. The setting of the reference positioning component and the reference position limiting block can improve the position of the ball-head positioning post in the reference positioning component on the concave surface of the reference position limiting block, thereby restricting the rotation of the lower half of the semi-circular gear rotating component. This allows the trolley pressure bar rotating drive part to smoothly descend and dock with the trolley when the trolley rotating transport part moves to the next standby position.

[0013] Furthermore, the trolley pressure bar rotation drive mechanism includes a set of upper track wall plates, a set of upper support columns, a set of upper connecting rods, a pressure bar semicircular gear, a pressure bar assembly, and a rotation drive mechanism. The upper track wall plates are arranged opposite to each other, and the lower part between the two upper track wall plates is connected by a set of upper support columns, while the upper part is fixedly connected to a fixed connecting plate. An upper semicircular track is provided on the inner side of the upper track wall plate. The upper connecting rod is located between the two upper track wall plates, and rollers are provided at both ends of the upper connecting rod. The rollers are located in the corresponding upper semicircular track. The pressure bar semicircular gear is located on the upper connecting rod, and the pressure bar semicircular gear cooperates with the mounting bar semicircular gear. The pressure bar assembly is located on the inner side of the pressure bar semicircular gear.

[0014] The rotary drive mechanism is located on the upper part of the trolley pressure bar rotary drive mechanism and cooperates with the pressure bar semi-circular gear. The fixed connecting plate is located above the two upper track wall panels.

[0015] Furthermore, the rotary drive mechanism includes a rotary drive motor, a power gear, and a reducer. The reducer is fixed to the inner side of the upper track wall panel, and its input end is equipped with a rotary drive motor. The power gear is located at the output end of the reducer, and the power gear meshes with the pressure bar semi-circular gear.

[0016] Preferably, an upper gear limiting block is provided below the fixed connecting plate, and a second groove is provided on the upper gear limiting block, which cooperates with the pressure bar semi-circular gear.

[0017] More preferably, the upper section of the lower track wall panel is provided with a protrusion, and the surface of the upper track wall panel is provided with a third groove; the protrusion and the third groove cooperate with each other.

[0018] Furthermore, the cross-section of the mounting bar semi-circular gear is provided with a first positioning groove, and a set of first positioning protrusions are provided circumferentially in the first positioning groove.

[0019] More preferably, the cross-section of the pressure bar semi-circular gear is provided with a set of second positioning grooves, and the first positioning protrusion cooperates with the second positioning grooves.

[0020] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0021] 1. The trolley for the rotatable sealing strip product described in this invention has a reasonable structural design. The strip loading trolley is placed on one side. The strip loading module of the trolley is driven to rotate to any angle by the strip pressing rotation drive mechanism of the trolley, so as to overcome the limitation of the punching direction caused by the concentrated configuration of the hydraulic cylinder of the single-sided multi-cavity tooling, and effectively improve the stability and convenience during impact.

[0022] 2. The mutual cooperation between the cross-section of the lower track wall plate and the cross-section of the upper track wall plate, as well as the mutual cooperation between the cross-section of the mounting bar semi-circular gear and the cross-section of the pressure bar semi-circular gear described in this invention, enables the trolley to self-position and lock, effectively ensuring the normal operation of the trolley and improving its operational stability. At the same time, it can reduce the number of trolley positioning devices on the equipment, thereby reducing the manufacturing cost of the equipment.

[0023] 3. The setting of the reference positioning component and the reference position limiting block in this invention can improve the top of the ball head positioning post in the reference positioning component on the concave surface of the reference position limiting block, and restrict the rotation of the lower half of the semi-circular gear rotating component, so that when the trolley rotating transport part moves to the last standby position, the trolley pressure bar rotating drive part can smoothly descend and dock with it.

[0045] Example 1

[0046] like Figures 1 to 7 The trolley for a rotatable sealing strip product shown includes: at least one sealing strip trolley 31, a lifting drive mechanism 32, and a fixed connecting plate 33.

The lower part of the two lower track wall plates 3111 is connected by the timing belt connector 3112, and the upper part is connected by a set of lower support columns 3120.

[0048] The upper part of the inner side of the lower track wall panel 3111 is provided with a lower semi-circular track. The two ends of the lower connecting rod 3113 are provided with rollers. The rollers are located in the corresponding lower semi-circular track. The mounting bar semi-circular gear 3114 is provided on the lower connecting rod 3113.

[0049] The planar guide wheel 3115 is located at the lower part of the lower track wall plate 3111, and the inclined guide wheel 3116 is located above the planar guide wheel 3115 and is installed on the inclined surface of the synchronous belt connector 3112.

[0050] like Figure 6 The synchronous belt connector 3112 shown is provided with a gear limiting block 3118, and the gear limiting block 3118 is provided with a groove, which cooperates with the lower mounting bar semi-circular gear 3114.

[0051] It also includes a set of reference positioning components 3119, one side of which is fixed to the inner wall of the lower track wall panel 3111, and it cooperates with the reference position limiting block 3117.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 7 The trolley pressure bar rotation drive mechanism 312 shown includes a set of upper track wall plates 3121, a set of upper support columns 3122, a set of upper connecting rods 3123, a pressure bar semi-circular gear 3124, a pressure bar assembly 3125, and a rotation drive mechanism 3126. The upper track wall plates 3121 are arranged opposite to each other, and the lower part of the two upper track wall plates 3121 is connected by a set of upper support columns 3122, while the upper part is fixedly connected to a fixed connecting plate 33. The inner side of the plate 3121 is provided with an upper semi-circular track. The upper connecting rod 3123 is located between the two upper track wall plates 3121, and the two ends of the upper connecting rod 3123 are provided with rollers. The rollers are located in the corresponding upper semi-circular track. The pressure bar semi-circular gear 3124 is located on the upper connecting rod 3123, and the pressure bar semi-circular gear 3124 cooperates with the mounting bar semi-circular gear 3114. The pressure bar assembly 3125 is located inside the pressure bar semi-circular gear 3124.

[0053] The rotary drive mechanism 3126 is located on the upper part of the trolley pressing bar rotary drive mechanism 312 and cooperates with the pressing bar semi-circular gear 3124.

[0054] The rotary drive mechanism 3126 includes a rotary drive motor 31261, a power gear 31262, and a reducer 31263. The reducer 31263 is fixed to the inner side of the upper track wall plate 3121, and its input end is provided with the rotary drive motor 31261. The power gear 31262 is provided at the output end of the reducer 31263, and the power gear 31262 meshes with the pressure bar semi-circular gear 3124.

[0055] The fixed connecting plate 33 is provided with an upper gear limiting block 331 below it. The upper gear limiting block 331 is provided with a second groove, which cooperates with the pressure bar semi-circular gear 3124.

[0056] The lower track wall plate 3111 has a protrusion 31111 on its upper cross section, and the upper track wall plate 3121 has a third groove 31211 on its surface; the protrusion 31111 and the third groove 31211 cooperate with each other. It should be noted that the protrusion 31111 is a trapezoidal convex surface, and the third groove 31211 is a trapezoidal concave surface. It can be imagined that the shapes of the protrusion 31111 and the third groove 31211 can be adjusted according to actual needs.

[0057] The cross-section of the mounting bar semi-circular gear 3114 is provided with a first positioning groove 31141, and a set of first positioning protrusions 31142 are provided circumferentially in the first positioning groove 31141. The cross-section of the pressing bar semi-circular gear 3124 is provided with a set of second positioning grooves 31242, and the first positioning protrusions 31142 cooperate with the second positioning grooves 31242.

[0058] The working method of the trolley for the rotatable sealing strip product described in this embodiment is as follows:

[0059] 1) The lifting drive mechanism 32 drives the trolley pressure strip rotation drive mechanism 312 to descend. The third groove 31211 on the upper track wall plate 3121 and the second positioning groove 31242 on the pressure strip semi-circular gear 3124 in the trolley pressure strip rotation drive mechanism 312 correspond to and engage with the protrusion 31111 on the lower track wall plate 3111 and the first positioning protrusion 31142 on the strip loading semi-circular gear 3114 in the trolley rotation conveying mechanism 311. At this time, the strip loading trolley is in a locked state. The upper and lower semi-circular tracks of the upper and lower parts, as well as the pressure strip semi-circular gear 3124 and the strip loading semi-circular gear 3114, are combined into one, and the pressure strip assembly 3125 presses and fixes the sealing strip.

[0060] 2): The rotary drive motor 31261 drives the power gear 31262 to rotate. The power gear 31262 drives the gear rotating assembly of the combined pressure bar semicircular gear 3124 and mounting bar semicircular gear 3114 to rotate along the combined upper and lower semicircular tracks, rotating to the required position for punching.

[0061] 3): After punching, the rotary drive motor 31261 drives the gear rotation assembly of the pressure bar semicircular gear 3124 and the mounting bar semicircular gear 3114 to rotate along the track where the upper semicircular track and the lower semicircular track are combined to the initial position through the power gear 31262.

[0062] 4): At this time, the ball-head positioning post in the reference positioning component 3119 is on the concave surface of the reference position limiting block 3117, which restricts the rotation of the lower half of the strip loading semi-circular gear 3114, so that when the trolley rotating conveying mechanism 311 moves to the next standby position, the trolley pressing strip rotating drive mechanism 312 can smoothly descend and dock with it.

[0063] Example 2

[0064] like Figures 1 to 18 The embodiment shown here describes an automated punching and cutting equipment for sealing strips based on a selectable sealing strip product cart. The sealing strip product cart in this automated punching and cutting equipment is the same as the cart in Embodiment 1. In addition, it also includes a frame 1, a circulating transport module 2, a set of integrated punching and cutting devices 4, and a strip loading and positioning module 5.

[0065] The circulating transport module 2 is mounted on the frame 1, and a set of horizontal moving modules 6 are located on both sides of the circulating transport module 2. The trolley rotating conveying mechanism 311 is connected to the circulating transport module 2. The trolley pressing bar rotating drive mechanism 312 is located above the trolley rotating conveying mechanism 311, and the trolley rotating conveying mechanism 311 and the trolley pressing bar rotating drive mechanism 312 cooperate with each other. The lifting drive mechanism 32 is connected to the suspension frame on the frame 1 through the mounting frame. The output end of the lifting drive mechanism 32 is connected to the fixed connecting plate 33, and the fixed connecting plate 33 is connected to the trolley pressing bar rotating drive mechanism 312.

[0066] The integrated punching device 4 is connected to the corresponding horizontal moving module 6, and the reloading device 4 cooperates with the rotary strip loading trolley 3. The strip loading positioning module 5 is located on the horizontal moving module 6 and on one side of the integrated punching device 4. This invention provides an automated punching equipment for sealing strips. By improving the structure of the punching equipment, its structural design is made more reasonable. It adopts a single-sided, single-cavity form for compact arrangement and merges multiple punching stations into one station. Furthermore, a hydraulic cylinder is centrally configured at the punching station as the punching power source. This reduces the size of the equipment, improves space utilization, and saves on the punching power source of subsequent punching fixtures, thus reducing manufacturing costs. Simultaneously, by using a servo-driven rotary trolley to rotate the sealing strip to the required entry angle, the limitation of the punching power direction caused by the centrally configured hydraulic cylinder is overcome, improving the stability and convenience of product punching.

[0067] The circulating transport module 2 includes a main support profile assembly 21, a synchronous belt main pulley 22, a synchronous belt driven pulley 23, a synchronous belt 24, a conveyor drive motor 25, a planar guide rail 26, an annular track frame 27, and an annular inclined guide rail 28. The synchronous belt main pulley 22 and the synchronous belt driven pulley 23 are positioned opposite each other at both ends of the main support profile assembly 21 and are connected by the synchronous belt 24. The conveyor drive motor 25 is installed on the outside of the main support profile assembly 21, and its output end is connected to the synchronous belt main pulley 22. The planar guide rail 26 is located below the synchronous belt 24. The annular track frame 27 is located on the outside of the main support profile assembly 21, and the annular inclined guide rail 28 is located on the inside of the annular track frame 27.

[0068] like Figures 14 to 17 The integrated punching device 4 shown includes a single-sided multi-cavity punching fixture and an integrated frame. The integrated frame is located at the punching station, and the single-sided multi-cavity punching fixture is located inside the integrated frame.

[0069] The single-sided multi-cavity punching fixture includes a main fixture mounting plate 41 and at least one single-cavity fixture 43. The main fixture mounting plate 41 is provided with at least one mounting station, and a single-cavity fixture mounting plate 42 is provided at the mounting station. The single-cavity fixture 43 is provided on the single-cavity fixture mounting plate 42, and the single-cavity fixture 43 is provided with a cutting cavity. The cutting cavity can be selected with different shapes of cavities as needed.

[0070] The integrated frame includes a base plate 44, a set of side plates 45, and an integrated mounting plate 46. The base plate 44 is located below the tooling mounting plate 41, the side plates 45 are located on both sides of the base plate 44, and the integrated mounting plate 46 is located on top of the side plates 45.

[0071] It also includes a punching power device 47, which is mounted on an integrated mounting plate 46 and cooperates with a single-cavity tooling 43.

[0072] The integrated punching device adopts a compact arrangement of single-sided single cavities to combine multiple punching fixtures into one integrated fixture. With the integrated punching power on the equipment, the punching power source required for the fixture is reduced. In addition, by integrating them into a frame, the need for repetitive frame parts caused by multiple punching fixtures is reduced, thereby reducing the overall manufacturing cost of the punching fixture.

[0073] The single-cavity tooling 43 includes a cavity frame 431, an infeed guide block 432, a punching assembly 433, a force-bearing block 434, and an outfeed guide frame 435. The cavity frame 431 is mounted on the single-cavity tooling mounting plate 42, the cutting cavity is mounted on the cavity frame 431, the infeed guide block 432 is located on the infeed side of the cavity frame 431, and a guide cavity is provided on it. The guide cavity cooperates with the cutting cavity.

[0074] The punching assembly 433 is located above the cavity frame 431, the force-bearing block 434 is located above the punching assembly 433, and the discharge guide frame 435 is located on the discharge port side of the cavity frame 431.

[0075] The tooling mounting plate 41 is provided with a front positioning block 411 and a rear clamping block 412 located at the front and rear of the single-cavity tooling mounting plate 42, respectively.

[0076] like Figure 2 The main mounting plate 41 shown is provided with a set of lower power limit blocks 413.

[0077] like Figure 1 , Figure 2 The main mounting plate 41 shown is located outside the single-cavity tooling mounting plate 42 and is positioned on the limiting member 410. The front positioning block, the rear clamping block, and the limiting member further improve the stability of the single-cavity tooling installation and prevent it from shifting during use.

[0078] The punching power device 47 includes a punching pressure plate 471 and a punching drive mechanism 472. The punching pressure plate 471 is located below the integrated mounting plate 46 and is connected to the integrated mounting plate 46 through a set of guide column assemblies. The punching drive mechanism 472 is mounted on the integrated mounting plate 46 and its output end is connected to the punching pressure plate 471.

[0079] The punching power unit 47 also includes a set of upper power limiting reference blocks 473, which are located below the punching pressure plate 471. The main mounting plate 41 is provided with limiting members 410 on the outer side of the mounting platform 42. The shapes of the cutting cavity and the guide cavity can be adjusted according to the product.

[0080] The working method of the automated punching equipment for sealing strip products described in this embodiment is as follows: 1): The product is mounted on the sealing strip sheet metal 31171 under the positioning guidance of the sealing strip positioning module 5;

[0081] 2): The conveyor drive motor 25 drives the synchronous belt main pulley 22 to rotate. During the operation of the synchronous belt main pulley 22, it will rotate through the synchronous belt 24 and the synchronous belt driven pulley 23.

[0082] 3): The trolley rotary conveyor 311 is driven by the synchronous belt 24 to the punching standby position. At the same time, during the movement, the trolley rotary conveyor 311 is guided by the cooperation of the annular inclined guide rail 28 and the inclined guide wheel 3116, and the offset gap in the left and right directions is eliminated, which lays a good foundation for the subsequent fitting and cooperation with the trolley pressing strip rotary drive mechanism 312.

[0083] 4): The lifting drive mechanism 32 drives the trolley pressure strip rotation drive mechanism 312 to descend. The third groove 31211 on the upper track wall plate 3121 and the second positioning groove 31242 on the pressure strip semi-circular gear 3124 in the trolley pressure strip rotation drive mechanism 312 are respectively engaged with the protrusion 31111 on the lower track wall plate 3111 and the first positioning protrusion 31142 on the strip loading semi-circular gear 3114 in the trolley rotation conveying mechanism 311. At this time, the strip loading trolley is in a locked state. The upper and lower semi-circular tracks and the pressure strip semi-circular gear 3124 and the strip loading semi-circular gear 3114 of the upper and lower parts are combined into one. The pressure strip assembly 3125 presses the sealing strip tightly onto the strip loading sheet metal 31171. At the same time, under the downward engagement of the trolley pressure strip rotation drive mechanism 312, the trolley rotation conveying mechanism 311 is limited and locked in the front, back and left and right directions.

[0084] 5): The rotary drive motor 31261 of the trolley pressing strip rotary drive mechanism 312 drives the power gear 31262 to rotate. The power gear 31262 drives the gear rotating assembly of the pressing strip semicircular gear 3124 and the mounting strip semicircular gear 3114 to rotate along the track that combines the upper and lower semicircular tracks, and stops after rotating the product to the required angle.

[0085] 6): The integrated punching device 4 moves forward to punch the product. After punching, the integrated punching station 4 moves backward. That is, the punching plate 471 moves downward under the drive of the punching drive mechanism 472 and collides with the force block 434 of the single-sided multi-cavity punching fixture. The force block 434 is driven by the force to punch the punching component 433 until the upper power limit reference block 473 mounted on the punching plate 471 and the lower power limit block 412 on the single-sided multi-cavity punching fixture are pressed together. At this time, the punching plate 471 stops moving downward. At this time, the punching of the sealing strip is completed. Then the punching plate 471 moves upward under the drive of the punching drive mechanism 472.

[0086] 7): The rotary drive motor 31261 of the trolley strip pressing rotary drive mechanism 312 drives the rotating part of the rotary strip loading trolley 3 to rotate back to the initial state. The cyclic transport module 2 then transports the trolley to the next position, and so on to complete the punching of the entire product.

[0087] It should be noted that before the equipment is in operation, a suitable single-cavity tooling needs to be selected according to the product to be cut. Each single-cavity tooling 44 is moved forward and inserted into the front positioning block 47 under the guidance of the left and right limiting parts 410. Then, the rear clamping block 48 presses against each single-cavity tooling 44 in turn and locks it. At this time, the single-sided multi-cavity punching tooling is assembled.

[0088] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
