Description

Technical Field

[0001] This application relates to the technical field of elevator car profile processing, and in particular to a cutting and blanking machine for processing elevator car profiles. Background Technology

[0002] Elevator car frames are typically assembled from various profiles, such as aluminum alloy and steel profiles, through welding and bolting. During the car manufacturing process, long strip profiles need to be cut to a fixed length using a laser cutting machine according to design dimensions to obtain sections that meet the needs of subsequent processing and assembly.

[0003] Currently, although existing laser cutting machines are equipped with corresponding cutting mechanisms, their cutting method typically involves tilting the profile support platform, allowing the cut profile to slide down the support platform under its own weight into the receiving rack. This cutting method still has certain shortcomings in practical applications: Firstly, the profile is prone to collision or friction with the receiving rack during the sliding process, resulting in scratches, bumps, and even localized deformation on the profile surface, thus affecting subsequent assembly accuracy and product quality. Secondly, after falling into the receiving rack, the profiles are usually stacked randomly, requiring manual assistance with hoisting equipment to transfer the cut profiles to the next process. This not only increases the labor intensity of operators and raises production costs but also reduces the continuity of the production line, hindering efficient connection and standardized flow between subsequent processing steps. Summary of the Invention

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The following description, in conjunction with the accompanying drawings, describes a cutting and blanking machine for processing elevator car profiles according to an embodiment of this application.

[0021] like Figures 1-7 As shown in the figure, a cutting and blanking machine for processing elevator car profiles according to an embodiment of this application may include a base plate 1, a cutting mechanism 2, a support assembly 3, a pushing mechanism 4, two sets of blanking mechanisms 5 and a transfer mechanism 6.

[0022] The cutting mechanism 2 is installed on the base plate 1 and is used for cutting the profile.

[0023] It should be noted that a feeding conveyor belt (not shown in the figure) is installed on one side of the cutting mechanism 2 described in the above embodiment, and the feeding conveyor belt is correspondingly arranged with two sets of rotating clamping assemblies 25. At the same time, in the initial state, the upper surface of the feeding conveyor belt is on the same plane as the support surface of the drag roller and the support surface of the support roller 33 in the rotating clamping assembly 25, thereby realizing the feeding process of the profile during cutting.

[0024] Specifically, such as Figure 1 and Figure 2As shown, the cutting mechanism 2 may include a feeding rack 21, a driving component 22, a laser cutter 23, a sliding assembly 24, and two sets of rotating clamping assemblies 25.

[0025] It should be noted that the drive unit 22 described in the above embodiment consists of a motor and a hydraulic cylinder (not shown in the figure), thereby realizing the adjustment of the height and direction of the laser cutter 23, thereby ensuring that the profile can be fully cut.

[0026] It should be noted that the laser cutter 23 described in the above embodiments is prior art, so it will not be described in detail here.

[0027] The feeding rack 21 is mounted on the base plate 1, the sliding assembly 24 is mounted on the base plate 1, and one end of the sliding assembly 24 is in contact with the feeding rack 21. The laser cutter 23 is mounted on the sliding assembly 24 through the drive component 22, and two sets of rotating clamping assemblies 25 are respectively mounted on the feeding rack 21 and the sliding assembly 24.

[0028] It should be noted that the rotating clamping assembly 25 described in the above embodiments can clamp and rotate the profile, thereby facilitating the laser cutter 23 to complete the cutting process of the profile around one circumference.

[0029] Understandably, the feeding rack 21 provides support for the profile during the feeding process. Subsequently, the rotating clamping component 25 in the feeding rack 21 and the sliding component 24 clamps and rotates the profile during the cutting process. Under the action of the sliding component 24, the position of the rotating clamping component 25 on the sliding component 24 is adjusted when cutting profiles of different lengths.

[0030] The sliding assembly 24 may include a mounting frame 241, a sliding plate 242, and a lead screw 243.

[0031] It should be noted that the lead screw 243 described in the above embodiments is driven by a servo motor (not shown in the figure).

[0032] It should be noted that a baffle is installed at one end of the sliding plate 242 described in the above embodiment, thereby blocking one end of the profile and preventing the profile from passing directly through the sliding plate 242, thus ensuring the consistency of the cutting length.

[0033] The mounting frame 241 is mounted on the base plate 1, the lead screw 243 is rotatably mounted on the mounting frame 241, one end of the sliding plate 242 is threaded onto the lead screw 243, the sliding plate 242 is slidably connected to the mounting frame 241, and a set of rotating clamping components 25 is mounted on the sliding plate 242.

[0034] Understandably, after the lead screw 243 is driven by the servo motor, the lead screw 243 drives the sliding plate 242 to move on the mounting frame 241, thereby adjusting the position of the rotating clamping component 25 in the sliding plate 242, and thus adapting to the support and clamping when cutting profiles of different lengths.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the rotating clamping assembly 25 may include a drive gear 251, a rotating ring 252, a driven gear 253, a clamping plate 254, a hinge plate 255, a floating spring 256, a support rod 257, and a plug-in rod 258.

[0036] It should be noted that the rotating ring 252 described in the above embodiment is C-shaped, and the opening direction is facing the feeding mechanism 5 in the initial state and after rotating one revolution.

[0037] The drive gear 251 is mounted on 241. The rotating ring 252 is rotatably mounted on 241 via the driven gear 253, and the driven gear 253 meshes with the drive gear 251. The clamping plate 254 is mounted on the rotating ring 252 via an electric push rod. The hinge plate 255 is hinged to one of the clamping plates 254 via a torsion spring. The floating spring 256 is mounted on the hinge plate 255. The support rod 257 slides through the hinge plate 255 and is connected to the floating spring 256. The insertion rod 258 is mounted on the support rod 257, and the corresponding clamping plate 254 has a hole for the insertion rod 258 to be inserted.

[0038] It should be noted that the drive gear 251 described in the above embodiments can be driven by a motor (not shown in the figure).

[0039] Understandably, after the profile enters the rotating clamping assembly 25 inside the feeding rack 21 and sliding assembly 24, the electric push rod drives the clamping plate 254 to complete the clamping of the profile. The hinge plate 255 descends together with one of the clamping plates 254 and contacts the corresponding clamping plate 254. The insertion hole opened on the corresponding clamping plate 254 contacts the insertion rod 258 and is inserted and fixed. Under continuous compression, the support rod 257 compresses the floating spring 256 and contracts in the hinge plate 255. After the clamping plate 254 completely fixes the profile, the motor drives the drive gear 251 to drive the driven gear 253 to rotate, so that the rotating ring 252 drives the clamping plate 254 and the profile to rotate synchronously. The support rod 257 and the plug rod 258 ensure stable positioning and prevent deviation, thereby ensuring the laser cutter 23 accurately cuts the profile in the circumferential direction. After cutting, the pusher assembly 4 pushes the cut profile. Before pushing, the electric pusher drives the clamping plate 254 to release the profile. During the pushing process, the hinge plate 255, support rod 257, and plug rod 258 are squeezed by the profile and unfold, avoiding the need for the sliding plate 242 to move back and forth during the cutting process, which would reduce the efficiency of clamping and cutting.

[0040] The support component 3 is mounted on the cutting mechanism 2 to provide support for the profile during and after cutting.

[0041] The support assembly 3 includes a cylinder 31, multiple sets of support plates 32, and multiple sets of support rollers 33.

[0042] The cylinder 31 is mounted on the base plate 1, the support plate 32 is mounted on the mounting frame 241, the support roller 33 is rotatably mounted on the support plate 32, and one set of support plates 32 is connected to the extended end of the cylinder 31.

[0043] Understandably, the support plate 32 and the support roller 33 provide support for the profile during and after cutting. Then, under the action of the cylinder 31, one set of support plates 32 and support rollers 33 is driven to rise and fall, thereby facilitating the movement of the sliding plate 242 and the rotating clamping assembly 25 on the mounting frame 241 to accommodate profiles of different lengths.

[0044] The feeding mechanism 4 is mounted on the cutting mechanism 2. The feeding mechanism 4 may include a driving component 41, a limiting rod 42, and a feeding component 43.

[0045] It should be noted that the drive component 41 described in the above embodiment is driven by a geared motor (not shown in the figure) to move the position of the pusher component 43.

[0046] The drive assembly 41 is mounted on the cutting mechanism 2, the limit rod 42 is slidably mounted on the cutting mechanism 2, the push assembly 43 is driven on the drive assembly 41, and the limit rod 42 is connected to the push assembly 43.

[0047] Understandably, after the drive assembly 41 is driven by the geared motor, the position of the pusher assembly 43 on the mounting frame 241 changes, thereby completing the support of the cut profile on the support plate 32 and the support roller 33, and during the movement of the limit rod 42, the limit rod 42 completes the limitation and auxiliary support of the pusher assembly 43 during the movement process.

[0048] Specifically, such as Figure 5 As shown, the drive assembly 41 may include a drive rod 411, two sets of transmission chains 412, two sets of transmission rods 413, and two sets of stroke screws 414.

[0049] It should be noted that a retaining ring is installed at the end of the stroke screw 414 away from the transmission rod 413 as described in the above embodiment, so as to prevent the pusher assembly 43 from falling off the stroke screw 414 when pushing the material.

[0050] The drive rod 411 is rotatably mounted on the cutting mechanism 2, and the two sets of stroke screws 414 are rotatably mounted on the cutting mechanism 2. The two sets of transmission rods 413 are connected to the two sets of stroke screws 414, and the drive rod 411 is connected to the two sets of transmission rods 413 respectively through two sets of transmission chains 412.

[0051] Understandably, after the drive rod 411 is driven by the geared motor, the two sets of transmission chains 412 drive the two sets of transmission rods 413 and the stroke screw 414 to rotate, thereby driving the pusher assembly 43 to move along the length of the profile through the stroke screw 414, thus realizing the pusher processing of the cut profile.

[0052] Specifically, such as Figure 5 As shown, the feeding assembly 43 may include a slider 431, a pusher plate 432, and a stop plate 433.

[0053] It should be noted that, in the above embodiment, after the push plate 432 is blocked by the subsequent profile during the return stroke, it will fold towards the feeding mechanism 5 under the pressure of the profile, and reset after passing the profile, so as to perform the next pushing operation.

[0054] The slider 431 is threaded onto the stroke screw 414, the push plate 432 is elastically hinged to the slider 431, and the abutment 433 is installed on the slider 431, with the abutment 433 abutting against the push plate 432.

[0055] It should be noted that the push plate 432 described in the above embodiment is elastically hinged to the slider 431 by a torsion spring, thereby realizing the reset process of the push plate 432 after folding.

[0056] Understandably, after the slider 431 is driven by the stroke screw 414, the pusher plate 432 completes the pushing process of the profile on the support plate 32 and the support roller 33 under the abutment of the abutment plate 433. During the return process after pushing, it is pressed by the subsequent profile and folds to avoid it. After passing the profile, it unfolds and resets under the action of the torsion spring so as to carry out continuous cyclic pushing operation.

[0057] The feeding mechanism 5 may include multiple supports 51 and feeding components 53.

[0058] It should be noted that the cutting component 53 described in the above embodiments can be driven by a geared motor (not shown in the figure) to realize the cutting process of the profile after cutting.

[0059] The feeding assembly 53 is driven and mounted on the bracket 51.

[0060] Understandably, the installation of the cutting assembly 53 is completed under the action of the bracket 51, and then the cutting assembly 53 is used to cut the profile.

[0061] Furthermore, such as Figure 6 As shown. One set of feeding mechanisms 5 is slidably mounted on the base plate 1 via a slide plate 7. The feeding mechanism 5 may also include multiple sets of auxiliary frames 52.

[0062] It should be noted that the feeding mechanism 5 described in the above embodiments can adjust the distance between the two feeding mechanisms 5 by means of the slide plate 7 according to the profiles of different lengths, so as to adapt to the feeding process of profiles of different lengths.

[0063] Multiple sets of auxiliary frames 52 are installed between adjacent supports 51.

[0064] Understandably, the auxiliary frame 52 is used to reinforce and fix the multiple sets of supports 51.

[0065] Specifically, such as Figure 6 As shown, the feeding assembly 53 may include multiple sets of drive rollers 531, feeding belt 532 and multiple sets of auxiliary plates 533.

[0066] It should be noted that, while the transmission roller 531 described in the above embodiment completes the transmission of the feeding belt 532, it further supports the profile, so as to avoid the situation where the feeding belt 532 is dented due to the excessive weight of the profile, which would prevent the profile from being fed.

[0067] Among them, multiple sets of transmission rollers 531 are rotatably mounted on the bracket 51, the feeding belt 532 is driven and sleeved on the transmission rollers 531, and multiple sets of auxiliary plates 533 are equidistantly mounted on the feeding belt 532.

[0068] Understandably, after the transmission roller 531 is driven by the geared motor, the feeding belt 532 moves the cut profile, and the auxiliary plate 533 moves synchronously during the movement, thereby assisting the profile to be transported to the feeding area and completing the automated feeding process.

[0069] The transfer mechanism 6 is located on one side of the support 51 to receive the profile and transport it to the next process.

[0070] It should be noted that the transfer mechanism 6 described in the above embodiments can be connected with the next process, thereby reducing the need for manual transfer and improving the overall production line efficiency.

[0071] Specifically, such as Figure 7 As shown, the transfer mechanism 6 may include a mounting frame 61, multiple sets of rotating components 62, and auxiliary components 63.

[0072] It should be noted that the rotating component 62 and the auxiliary component 63 described in the above embodiments are driven by a geared motor, multiple sets of transmission wheels, and a chain (not shown in the figure), respectively.

[0073] The mounting bracket 61 is mounted on the base plate 1, and the bracket 51 near the mounting bracket 61 is provided with a clearance groove. The rotating component 62 and the auxiliary component 63 are both mounted on the mounting bracket 61.

[0074] It should be noted that one end of the mounting bracket 61 described in the above embodiment is supported by the bracket 51 to ensure the stability of the profile during transportation.

[0075] Specifically, such as Figure 7 As shown, the rotating assembly 62 may include a support plate 621 and a rotating roller 622.

[0076] The support plate 621 is mounted on the mounting frame 61, and the rotating roller 622 is rotatably mounted between the support plate 621 and the mounting frame 61.

[0077] Understandably, the installation of the rotating roller 622 is completed under the action of the support plate 621, and the transfer of the cut profile is completed under the rotation of the rotating roller 622.

[0078] Specifically, such as Figure 7 As shown, the auxiliary component 63 may include a fixed plate 631 and multiple sets of auxiliary rollers 632.

[0079] The fixed plate 631 is mounted on the mounting frame 61, and multiple sets of auxiliary rollers 632 are rotatably mounted on the fixed plate 631.

[0080] Understandably, the installation of the auxiliary roller 632 is completed under the action of the fixed plate 631, and the auxiliary roller 632 prevents the profile from shifting or getting stuck during the conveying process on the rotating roller 622, thus ensuring the smoothness of the material feeding and conveying.

[0081] The above-described implementation method can effectively reduce the impact and damage to profiles during the material cutting process, ensuring that product quality is not affected; at the same time, it can realize the orderly acceptance and automatic transfer of profiles, significantly reduce the intensity of manual labor, and improve the automation level and turnover efficiency of the production line.

[0082] Specifically, this application provides a cutting and blanking machine for processing elevator car profiles, which can be used for precise cutting and automatic unloading and transfer of elevator car profiles. In actual operation, the personnel first feed the profile to be processed into the feeding rack 21 via the feeding conveyor belt. The profile then enters the rotating clamping assembly 25 located on the feeding rack 21. In the initial state, the upper surface of the feeding conveyor belt, the support surface of the drag roller in the rotating clamping assembly 25, and the support surface of the support roller 33 are on the same plane, ensuring that the profile enters smoothly. According to the preset cutting length, the servo motor drives the lead screw 243 to rotate. The lead screw 243 drives the sliding plate 242 to slide along the mounting frame 241, adjusting the distance between the two sets of rotating clamping assemblies 25 so that the position of the profile to be cut is aligned with the laser cutter 23.

[0083] After adjustment, the electric push rods of the two sets of rotating clamping assemblies 25 drive the clamping plates 254 to clamp both ends of the profile. One set of clamping plates 254 drives the hinge plate 255 to move synchronously. The insertion rod 258 at the end of the support rod 257 is inserted into the insertion hole of the other set of corresponding clamping plates 254 to form a lock. The support rod 257 compresses the floating spring 256 and retracts in the hinge plate 255 to ensure stable clamping without deviation. Subsequently, the drive component 22 drives the laser cutter 23 to move above the profile. The motor drives the drive gear 251 to rotate. The drive gear 251 drives the rotating ring 252 and the profile to rotate synchronously through the driven gear 253. The laser cutter 23 performs circumferential cutting on the profile. During the cutting process, the support plate 32 and the support roller 33 provide stable support for the profile from below to prevent the profile from sagging due to gravity and affecting the cutting accuracy.

[0084] After cutting, the electric push rod drives the clamping plate 254 to release the profile. The support rod 257 and the insertion rod 258 unfold and reset with the hinge plate 255, and the cut profile falls onto the support roller 33 on the support plate 32. Subsequently, the pushing mechanism 4 starts, and the reduction motor drives the drive rod 411 to rotate. The drive rod 411 drives the two sets of transmission rods 413 and the stroke screw 414 to rotate synchronously through two sets of transmission chains 412. The stroke screw 414 drives the slider 431 to move along the length of the profile. The slider 431 drives the push plate 432 to move forward. Under the limiting action of the abutment plate 433, the push plate 432 remains vertical, pushing the cut profile on the support roller 33 to one side, so that it falls onto the feeding belt 532 of the feeding mechanism 5. During the material pushing process, the electric push rod drives the clamping plate 254 to release the profile. During the material pushing process, the hinge plate 255, support rod 257, and plug rod 258 are unfolded by the pressure of the profile, avoiding the need for the sliding plate 242 to move back and forth during the cutting process, which would reduce the efficiency of clamping and cutting. After the material pushing is completed, the slider 431 moves in the opposite direction to reset. During this process, the push plate 432 is pressed by the subsequent profile and folds towards the bracket 51 to avoid it. After passing the profile, it unfolds and resets under the action of the torsion spring.

[0085] Driven by the transmission roller 531, the feeding belt 532 rotates, causing the auxiliary plate 533 to move synchronously, conveying the profile towards the transfer mechanism 6. The profile enters the transfer mechanism 6 through the clearance groove on the bracket 51. The rotating roller 622 rotates under the drive of the geared motor, continuing to convey the profile forward. The auxiliary roller 632 provides lateral restraint for the profile, preventing it from shifting or getting stuck during transport, and finally conveys the profile to the next process. The distance between the two feeding mechanisms 5 can be adjusted by the slide plate 7 to accommodate the feeding requirements of profiles of different lengths. During the entire cutting process, the drive component 22 can drive the laser cutter 23 to adjust at different heights and directions to ensure sufficient cutting of the profile; the rotational motion of the profile after being clamped, combined with laser cutting, achieves circumferential cutting; the unidirectional folding pusher design of the pushing mechanism allows it to automatically avoid subsequent profiles on the return trip, achieving continuous cyclic operation. The entire cutting and feeding process achieves automatic length adjustment, automatic clamping and rotation, automatic cutting, automatic pushing, automatic feeding and automatic transfer, reducing manual intervention and improving production efficiency and product quality.

[0086] In summary, the cutting and blanking machine for processing elevator car profiles according to the embodiments of this application can effectively reduce the impact and damage to the profiles during the blanking process, ensuring that the product quality is not affected; at the same time, it realizes the orderly acceptance and automatic transfer of profiles, significantly reducing the intensity of manual labor and improving the automation level and turnover efficiency of the production line.
