Description

Technical Field

[0001] The present invention relates to the technical field related to profile processing, and in particular to a double-station cutting device for profile extrusion processing. Background Art

[0002] Profiles, as basic components in the industrial field, are widely used in construction, transportation, aerospace, and mechanical processing. The cross-sections of profiles vary during specific use, including rectangular, U-shaped, H-shaped, angle iron, T-shaped and other types. As the industry's requirements for profile processing accuracy and production efficiency continue to increase, the technical bottlenecks of existing cutting devices are becoming increasingly prominent.

[0003] Traditional cutting equipment mostly adopts a single-station design and can only complete the cutting of one profile at a time. In addition, the existing equipment relies on manual rulers or fixed blocks for positioning. The cumulative cutting error increases linearly with the increase in the number of processing.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figure 1-11 As shown, an embodiment of the present application discloses a double-station cutting device for profile extrusion processing, including a base 1, on which are arranged, from back to front, a transmission mechanism 3 for assisting the profile to move from back to front, a cutting mechanism 2 for cutting two profiles at the same time, and a locking mechanism 4 for increasing stability during the profile cutting operation.

[0035] The cutting mechanism 2 includes a fixed bracket 21 provided on the base 1, a lifting assembly 22 provided on the fixed bracket 21, a cutting groove symmetrically opened on the base 1, a supporting spring rod 23 symmetrically installed on the base 1, a supporting plate 24 installed on the supporting spring rod 23, a cutting knife 25 symmetrically installed at the lower end of the supporting plate 24 and cooperating with the cutting groove, and the cutting knife 25 adopts an electric circular saw;

[0036] By adopting the above technical solution, when the cutting position of the profile is determined during operation, the profile is positioned and clamped by the locking mechanism 4, and the lifting component 22 squeezes the support plate 24, and the cutting knife 25 is driven by the support plate 24 to complete the cutting process of the profile.

[0037] The lifting assembly 22 includes a control cylinder 221 arranged on the fixed bracket 21, a control board 222 is installed at the lower end of the control cylinder 221, lifting slots are symmetrically opened on the fixed bracket 21, and a lifting frame 223 is symmetrically installed on the control board 222. The lifting frame 223 is slidably arranged in the lifting slot and is rotatably connected to the linkage rod 34.

[0038] The transmission mechanism 3 includes a rectangular groove symmetrically opened on the base 1, a locking assembly 31 is slidably provided in the rectangular groove, an adjustment assembly 32 is connected between the two locking assemblies 31, a sliding groove is symmetrically opened on the side wall of the base 1, a sliding block 33 is slidably provided in the sliding groove, the sliding block 33 is connected to the locking assembly 31, and a linkage rod 34 is provided between the sliding block 33 and the lifting assembly 22 through a bearing, and a push groove is symmetrically opened on the base 1, and auxiliary rollers are evenly spaced in the push groove;

[0039] By adopting the above technical solution, the extruded profile is placed on the auxiliary roller of the base 1 in preparation for cutting. During work, the control cylinder 221 on the lifting assembly 22 is first started to drive the lifting frame 223 on the control panel 222 to lift and adjust. During the movement, the lifting frame 223 drives the locking assembly 31 to move back and forth through the cooperation between the linkage rod 34 and the sliding block 33. When the locking assembly 31 moves from back to front, the adjusting assembly 32 controls the locking assembly 31 to clamp the profile, and drives the profile to be cut to be fed through the locking assembly 31. When the locking assembly 31 moves from front to back, the adjusting assembly 32 controls the locking assembly 31 to release the profile (it should be noted that when the profile has not moved to the position to be cut, the downward movement trajectory of the control panel 222 during this process is above the support plate 24, ensuring that the position of the cutting knife 25 does not change during the feeding process of the profile).

[0040] The locking assembly 31 includes an adjusting frame 311 slidably set on the base 1, the adjusting frame 311 is connected to the sliding block 33, and a locking groove is symmetrically opened on the adjusting frame 311. A locking frame 312 is slidably set in the locking groove, and a locking spring rod 313 is set between the locking frame 312 and the locking groove. A mounting column is set on the inner wall of the middle part of the adjusting frame 311 through a bearing, and a locking gear 314 is set at the lower end of the mounting column; a mounting rod 315 is set on the mounting column, and the mounting rod 315 is connected to the locking frame 312 through a pin shaft.

[0041] The adjustment assembly 32 includes an adjustment plate 321 installed between two adjustment frames 311, an adjustment slot is provided on the adjustment frame 311, a gear bar 323 is slidably provided on the inner wall of the adjustment frame 311, a two-way cylinder 322 is installed on the adjustment plate 321, and an adjustment rod is installed on the two-way cylinder 322, which slides through the adjustment slot and is connected to the gear bar 323.

[0042] When the locking assembly 31 needs to clamp the profile, the two-way cylinder 322 is started to control the gear bar 323 on the adjusting rod to drive the locking gear 314 to rotate. The locking gear 314 synchronously drives the mounting rod 315 to rotate during rotation. The mounting rod 315 synchronously controls the two locking frames 312 to move toward each other during the rotation process. The two locking frames 312 synchronously move toward the profile to clamp the profile, ensuring that the locking assembly 31 can synchronously drive the profile forward to the working position of the cutting mechanism 2 when following the movement of the sliding block 33, thereby ensuring the accuracy of the profile cutting length, and can simultaneously control the two profiles to perform cutting operations synchronously, which can improve the efficiency of the profile cutting process while ensuring the accuracy of the profile cutting.

[0043] The locking mechanism 4 includes a control component 1 41 arranged on the lower end surface of the base 1, and the two ends of the control component 1 41 are symmetrically connected with clamping components 42, and the upper end surface of the base 1 is provided with a control component 2 43, and the control component 2 43 is symmetrically connected with a positioning component 44 that cooperates with the control component 1 41. A blanking chute is symmetrically opened on the base 1, and the control component 1 41 and the clamping component 42 are located on the rear side of the cutting mechanism 2, and the control component 2 43 and the positioning component 44 are located on the front side of the cutting mechanism 2. In the process of cutting the profile by the cutting mechanism 2, the stability of the profile during the cutting operation is ensured by the mutual cooperation between the clamping component 42 and the positioning component 44, and the cut profile is discharged through the blanking chute.

[0044] The control component 41 includes a bidirectional motor 411 installed on the base 1, and a bidirectional screw 412 is symmetrically arranged on the output shaft of the bidirectional motor 411. The bidirectional screw 412 is connected to the side wall of the base 1 through a bearing, and a moving slider 413 is symmetrically arranged on the bidirectional screw 412.

[0045] The clamping assembly 42 includes a clamping groove provided on the base 1, a clamping frame 421 is slidably provided in the clamping groove, the clamping frame 421 is installed on the movable slider 413, an extrusion groove is symmetrically provided on the clamping frame 421, an extrusion frame 422 is installed in the extrusion groove through a torsion spring, a driven groove cooperating with the extrusion groove is symmetrically provided on the clamping frame 421, a driven frame 423 is slidably provided in the driven groove, an extrusion spring rod is provided between the driven frame 423 and the inner wall of the driven groove, an execution frame 424 is slidably provided in the driven frame 423, the execution frame 424 is attached to the clamping frame 421, a lifting member is provided on the base 1, and the execution frame 424 is slidably provided on the lifting member.

[0046] The lifting member includes a lifting cylinder 425 installed on the base 1, a lifting frame 426 is installed on the lifting cylinder 425, and an execution slide 427 cooperating with the execution frame 424 is installed on the lifting frame 426. The execution frame 424 is slidably connected to the execution slide 427.

[0047] By adopting the above technical solution, when the processed profile is a U-shaped or H-shaped structure, after the profile is cut to a certain length, the bidirectional motor 411 is started to control the two bidirectional screw rods 412 to rotate synchronously. During the rotation process, the bidirectional screw rods 412 synchronously drive the two clamping frames 421 to clamp the profile. The clamping frames 421 are wrapped with rubber or provided with rubber strips on their surfaces, which can increase friction while preventing the clamping force from damaging the profile.

[0048] When the profile to be processed is an angle iron or a triangular structure, the lifting cylinder 425 is started to control the lifting frame 426 to move upward, and the lifting frame 426 simultaneously drives the execution slide 427 to adjust upward. The execution slide 427 simultaneously pushes the execution frame 424 to move upward during adjustment. When the sliding block 413 drives the clamping frame 421 to move toward each other, the execution frame 424 first contacts the angle iron. During this process, the execution frame 424 applies pressure to the extrusion frame 422 under the extrusion of the reaction force of the angle iron. After being subjected to the force, the extrusion frame 422 rotates toward the end face of the angle iron and extrudes the angle iron through the extrusion frame 422 in two directions, thereby synchronously positioning the angle iron, thereby improving the stability of the angle iron during the cutting operation.

[0049] The second control component 43 includes a push cylinder 431 mounted on the base 1, a push frame 432 mounted on the push cylinder 431, a vacuum air pump 434 mounted on the push frame 432, a double-axis cylinder 433 mounted on the push frame 432, and a limit member 45 symmetrically mounted on the double-axis cylinder 433;

[0050] The positioning assembly 44 includes a positioning frame 441 installed on the pushing frame 432, and positioning holes are evenly opened on the end face of the positioning frame 441. A positioning rod 442 is slidably arranged in the positioning hole, and positioning grooves are evenly opened on the positioning rod 442. An air bag 443 is installed on the inner wall of the positioning frame 441, and the air bag 443 is connected to the vacuum air pump 434 through an air pipe.

[0051] The limiting assembly 45 includes a feed groove provided on the positioning frame, a limiting frame 451 is slidably provided in the feed groove, the limiting frame 451 is installed on the dual-axis cylinder 433, and positioning cards 452 that cooperate with the positioning groove are evenly provided on the limiting frame 451.

[0052] The positioning rod 442 that has not been squeezed wraps the end face of the profile, and then the double-axis cylinder 433 drives the positioning card 452 on the limit frame 451 to be inserted into the positioning groove, and the positioning rod 442 cooperates with the clamping assembly 42 to position and lock the profile, thereby improving the stability of the profile during the cutting operation. After the cutting operation is completed, the pushing cylinder 431 and the limit assembly 45 are reset, and then the vacuum air pump 434 is started to inflate the airbag 443. The inflated airbag 443 squeezes the positioning rod 442. During the reset process, the positioning rod 442 pushes the cut profile into the blanking chute for discharge.

[0053] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
