Description

Technical Field

[0001] The utility model relates to the technical field of profile cutting, in particular to a traction-type profile interruption cutting device. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness through rolling, extrusion, casting and other processes. This type of material has a certain appearance size, a certain cross-section shape, and certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, and are often used in building structures and manufacturing and installation. Mechanical engineers can select the specific shape, material, heat treatment state, mechanical properties and other parameters of the profile according to the design requirements, and then divide the profile according to the specific size and shape requirements, and then further process or heat treat it to achieve the design accuracy requirements. The material, specifications and dimensions of the profile can refer to the corresponding national standards. In the process of dividing the profile, an automatic interruption saw is required. The automatic interruption saw is an automated equipment that can achieve the profile cutting effect.

[0003] With the application of aluminum profiles in transportation and other fields, the quality requirements of aluminum profiles are getting higher and higher. There is an urgent need for traction equipment to improve the production quality and qualified rate of aluminum profiles. The stability of traction equipment in operation is closely related to the quality of aluminum production. In the automated production process of continuous extrusion molding of aluminum profiles, a sawing device needs to be set. The traction machine currently configured with a small tonnage extruder has been troubled by synchronous interruption. Because if the traction machine itself has an interruption saw, the traction machine body is heavy, slow to respond, and the structure is complex and the production cost is high. In order to meet the requirements of light weight and fast response, the traction machine itself does not have an interruption saw. The interruption saw is linked with the traction machine through a synchronization device, but the current synchronization device cannot achieve a 100% synchronization effect. There is always a deviation between them, which leads to the production quality of aluminum profiles has not been improved. Utility Model Content

[0004] In view of the above problems, the utility model provides a traction-type profile interrupted cutting device, which enables the center cutting saw to maintain synchronization with the lower traction machine by setting a synchronization mechanism, thereby ensuring stable cutting of the profile. A unidirectionally separable locking plate and a jaw plate are used to achieve synchronous drive, effectively preventing the center cutting saw from separating from the lower traction machine.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A traction-type profile interruption cutting device comprises a traction frame and a cutting frame arranged side by side, an upper traction machine and a lower traction machine for traction of profile cutting are slidably arranged on the traction frame, and a middle cutting saw for cutting the profile is slidably arranged on the cutting frame; a conveying frame is arranged between the traction frame and the cutting frame, and a plurality of conveying roller groups for conveying the profile are installed on the conveying frame; a synchronization mechanism is fixedly arranged on the middle cutting saw, and the synchronization mechanism connects the middle cutting saw and the lower traction machine.

[0007] As a further solution of the utility model: the center-cut saw is provided with a dust suction fan for collecting cutting debris.

[0008] As a further solution of the utility model: the conveying roller group includes a support frame installed on the conveying frame, a connecting plate is fixedly provided on the support frame, and a supporting roller is rotatably installed on the connecting plate.

[0010] As a further solution of the utility model: the synchronization mechanism includes a jaw plate fixedly connected to the lower traction machine and a locking plate slidably arranged on the center cutting saw, and the locking plate and the jaw plate are both provided with one-way separable jaws.

[0011] As a further solution of the utility model: the synchronization mechanism includes a lock seat fixedly arranged on the center cutting saw, a lock support is slidably arranged on the lock seat, the lock plate is fixedly connected to the lock support, a cylinder support is fixedly arranged on the lock seat, a lock cylinder is rotatably installed on the cylinder support, and the output end of the lock cylinder is connected to the lock support.

[0025] The center-cut saw 7 is provided with a dust suction fan 9 for collecting cutting debris. The dust suction fan 9 is provided to collect the cutting dust, thereby effectively preventing the dust from splashing and affecting the working environment, and preventing the dust from splashing and causing damage to the staff.

[0026] The conveying roller group 5 includes a support frame 53 installed on the conveying frame 4, a connecting plate 54 is fixedly provided on the support frame 53, and a supporting roller 55 is rotatably installed on the connecting plate 54. The conveying roller group 5 includes a bearing seat 51 fixedly installed on the conveying frame 4, a conveying shaft 52 is fixedly installed on the bearing seat 51, the support frame 53 is fixedly connected to the conveying shaft 52, a driving plate 56 is fixedly connected to the conveying shaft 52, a driving cylinder 57 is rotatably installed on the conveying frame 4, and the output end of the driving cylinder 57 is rotatably connected to the driving plate 56.

[0027] The driving cylinder 57 drives the driving plate 56 and the conveying shaft 52 to rotate, thereby driving the supporting roller 55 to rotate and adjust its height relative to the conveying frame 4, so that the upper surface of the object maintains the same height when cutting different objects, thereby ensuring the stability of the cutting.

[0028] The synchronization mechanism 8 includes a jaw plate 81 fixedly connected to the lower tractor 3 and a locking plate 86 slidably provided on the center-cut saw 7, and the locking plate 86 and the jaw plate 81 are both provided with jaws that can be separated in one direction. The synchronization mechanism 8 includes a locking seat 82 fixedly provided on the center-cut saw 7, a locking support 87 slidably provided on the locking seat 82, the locking plate 86 fixedly connected to the locking support 87, a cylinder support 83 fixedly provided on the locking seat 82, a locking cylinder 84 rotatably installed on the cylinder support 83, and an output end of the locking cylinder 84 is connected to the locking support 87.

[0029] A pin shaft 88 is fixedly provided on the lock support 87, and a lock push block 85 is slidably connected to the middle of the pin shaft 88.
