Description

Technical Field

[0001] The invention belongs to a laser section steel processing line, is mainly used for section steel processing, and particularly relates to a section steel pushing mechanism and a laser cutting machine. Background Art

[0002] At present, the laser steel processing lines on the market push the steel to the processing area by clamping the steel web. As shown in the figure, pushing the steel by clamping the web will cause the following defects:

[0003] 1. The horizontal center position of steel sections of different specifications will change. If the clamping arm is moved manually, the moving distance is not accurate and the efficiency is low. Each time a steel section of different specifications is processed, it needs to be moved manually. The operator needs to move the clamping arm manually on the conveyor frame, which poses a safety hazard. If a horizontal moving servo and guide are installed, the cost is high and power supply is required, which is not energy-saving.

[0004] 2. The web heights of steel sections of different specifications are also different. The web heights of large-sized steel sections are high, so it is no problem to clamp the upper and lower sections by extending the clamping claws into the middle of the steel section. However, the internal space of small-sized steel sections is small, so the size of the clamping claws needs to be designed to be very small so as not to interfere with the steel section and the conveyor wheel.

[0005] 3. The force point of the clamping steel web is too far away from the pushing drive, forming a large force arm, which will require a greater driving force when pushing. Summary of the invention

[0022] A method for pushing a section steel, using the pushing mechanism, comprises:

[0023] Step 1: Vertical position

[0025] The top of the steel wing plate acts on the touch plate to move upward, and the touch plate compresses the spring body. The touch plate drives the limit seat and the induction sheet metal upward through the guide column to block the infrared sensor, giving the system a signal of arrival;

[0037] In the preferred embodiment, the laser cutting machine also includes a support frame and a loading trolley.

The lifting frame is an X-shaped frame and one side of the X-shaped frame is a joint point that slides relative to the bottom plate, and the other side of the joint point is rotatably arranged relative to the bottom plate.

[0038] A steel section cutting method using a laser cutting machine, comprising:

[0039] Step 1: Steel loading

[0040] The operation of the lifter drives the top plate upward relative to the bottom plate, and the steel top support placed on the support frame is separated from the support frame;

[0041] The driving mechanism drives the walking mechanism to move along the track frame and approach the loading rack, and transports the steel to the conveying roller on the loading rack;

[0042] After being transported to the top of the conveying roller, the lifter works in the reverse direction to drive the top plate downward relative to the bottom plate, and the steel is loaded onto the conveying roller until the top plate is separated from the steel. The driving mechanism drives the walking mechanism to move along the track frame and away from the loading frame to the initial position;

[0043] Step 2: Positioning of steel sections

[0044] After the main cylinder drives the moving frame to move along the crossbeam to a position that matches the specifications of the profiled steel, the auxiliary cylinder 1 or 2 drives the corresponding clamping roller to fit the profiled steel onto the positioning wheel;

[0045] Auxiliary cylinder 1 or auxiliary cylinder 2 drives the clamping roller to reset, and the main cylinder drives the moving frame to reset;

[0046] Step 3: Clamping and conveying

[0049] The top of the steel wing plate acts on the touch plate to move upward, and the touch plate compresses the spring body. The touch plate drives the first and sensing sheet metal to move upward to the shielding infrared sensor through the guide column, giving the system a signal of arrival;

[0059] Repeat steps 1 to 3 until the steel section cutting operation is completed.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] 1. The present invention adopts a wing plate clamping and conveying method when conveying steel sections. Compared with the original web plate clamping and conveying method, it can better adapt to workpieces of different sizes and specifications. At the same time, the force arm during transportation is greatly reduced, which is beneficial to improving structural stability and achieving high efficiency and energy saving. By switching to the method of clamping wing plates, the space is large enough, the rigidity of the chuck can be strengthened to meet the clamping requirements of steel sections of different specifications. Multiple clamping and pushing of a single steel section can be achieved, and the pushing stroke is shortened. (For example: a 14-meter steel section is first clamped at the 7-meter position. When the 7-meter position steel section is fully processed, the clamping assembly is moved back 7 meters to push the 7-meter steel section. This reduces the pushing stroke, space occupied and moving distance.)

[0062] 2. The present invention arranges the push arm and the Z-axis slide in a rotatable manner, and sets a T-shaped connecting pin and a spring member between the push arm and the Z-axis slide. The spring member initially biases the push arm toward the side close to the Z-axis slide. After being clamped by the clamping assembly, the push arm is arranged almost parallel to the steel section. This can better ensure that the push force is concentrated in the center of the push arm, making the structure of the push arm more stable.

[0063] 3. The present invention also compresses the spring body upward after the touch plate contacts the wing plate, so that the sensing sheet metal blocks the infrared sensor, and transmits the arrival signal to the system. The system gives instructions to the fixed clamp and the movable clamp to complete the clamping of the steel wing plate. When clamping, the movable clamp first contacts the side wall of the steel wing plate, and then the fixed clamp and the pushing arm overcome the action of the spring part, so that the clamping assembly clamps the top of the fixed steel wing plate to ensure that it is transported in a straight line along the positioning roller to the cutting station.

[0064] 4. The laser cutting machine of the present invention is also provided with a loading car and a loading rack. The loading car is used to transport the steel to the loading rack. The loading rack is provided with a main and auxiliary cylinders. The main and auxiliary cylinders and the steel are pushed onto the positioning wheel to complete the positioning of the steel. It can be selected for workpieces of different sizes. When it is implemented for small-sized workpieces, the auxiliary cylinder 1 and the clamping roller on the clamping plate 1 are used to achieve the tight positioning of the workpiece; when it is implemented for large-sized workpieces, the auxiliary cylinder 2 and the clamping roller on the clamping plate 2 are used to achieve tight positioning. In this way, the specifications of the traditional positioning cylinder can be reduced. If a cylinder with a large stroke is directly used, the feeding efficiency will be affected.

[0078] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0080] like Figures 2 to 8 As shown, a section steel pushing mechanism comprises:

[0081] A push bracket 100, wherein a plurality of support legs are provided at the bottom of the push bracket 100;

[0082] A moving platform 101, the moving platform 101 is slidably matched on the pushing bracket 100;

[0083] Driver 1, the driver 1 is installed on the moving platform 101 and drives the moving platform 101 to move along the pushing bracket 100;

[0084] A Z-axis slide 106, which is mounted on the moving platform 101 and can be adjusted up and down relative to the moving platform 101;

[0085] Driver 2, which is mounted on the moving platform 101 and drives the Z-axis slide 106 to move up and down along the moving platform 101;

[0086] A push arm 102, the push arm 102 is rotatably mounted on the side of the Z-axis slide 106;

[0087] The clamping assembly is installed at one end of the push arm 102 away from the Z-axis slide 106 and is used to clamp the steel wing plate.

[0088] In the pushing mechanism, the clamping assembly includes a fixed clamping plate 104 fixedly mounted on the pushing arm 102, a movable clamping plate 103 rotatably mounted on one side of the fixed clamping plate 104, and a hydraulic cylinder 105 mounted on the fixed clamping plate 104 and having an output end driving the movable clamping plate 103 to rotate. A fixed plate 114 is mounted on the pushing arm 102, and a through hole is provided on the pushing arm 102. A tension spring 119 is mounted on the fixed plate 114, and the tension spring 119 passes through the through hole and is connected to the end of the movable clamping plate 103. The rear side of the moving platform 101 is equipped with a hydraulic system of the hydraulic cylinder 105. In the free state, the clamping area between the fixed clamping jaw 105 and the movable clamping jaw 104 has a safety distance of 10 mm from the steel wing plate to ensure that the clamping jaws interfere with the steel wing plate in the middle during the lowering and clamping process.

[0089] During clamping, the output end of the hydraulic cylinder 105 moves outward to push the end of the movable clamping plate 103, bringing the movable clamping plate 103 close to the fixed clamping plate 104 and first abutting against the inner wall of the wing plate. After abutting, the output end of the hydraulic cylinder 105 continues to move outward to push the movable clamping plate 103 to bring the fixed clamping plate 104 close to and fit against the outer wall of the wing plate. When the hydraulic cylinder 105 is retracted, the tension spring 119 resets the movable clamping plate 103. After clamping, the driver drives the moving platform 101 to transport the steel to the cutting station along the pushing bracket 100.

[0090] In the pushing material mechanism, if Figure 7 As shown, a fixed seat 1041 and an infrared sensor 1042 installed on the top are installed on one side of the fixed splint 104 relative to the movable splint 103, two guide columns 1046 arranged for vertical sliding are installed on the fixed seat 1041, a limiting seat 1044 is installed on the top of the guide column 1046, a sensing sheet metal 1043 is installed on the limiting seat 1044, a touch panel 1045 is installed on the bottom of the guide column 1046, and a spring body 1047 is sleeved on the outer side of the guide column 1046 between the touch panel 1045 and the fixed seat 1041.

[0091] When the Z-axis slide 106 moves downward, the touch plate 1045 moves downward to act on the top of the wing plate, and the touch plate 1045 moves upward to compress the spring body 1047. The limit seat 1044 drives the sensing sheet metal 1043 to move upward to block the infrared sensor 1042 to give an in-place signal and transmit it to the system.

[0092] The push arm 102 is provided with a T-shaped hole, in which a spring member 121 and a T-shaped connecting pin 120 inserted into the inner side of the spring member 121 are installed, and the end of the T-shaped connecting pin 120 is connected and fixed to the Z-axis slide 106 .

[0093] During clamping, when the fixed clamping plate 104 approaches the outer wall of the wing plate, the spring member 121 is compressed and the pushing arm 102 is eventually moved outwards by a certain angle.

[0094] In the pushing material mechanism, if Figure 4 As shown, two symmetrically distributed vertical slide rails 107 are installed on the side of the moving platform 101;

[0095] Driver 2 includes a motor base 110 installed on the top side of the moving platform 101 and a servo motor 2 111 installed on the motor base 110. The servo motor 2 111 is connected to the Z-axis screw 109 via a synchronous belt. The Z-axis slide 106 is installed on the Z-axis screw 109, and the back of the Z-axis slide 106 is installed with a vertical slider 108 and a vertical slide rail 107 for sliding cooperation.

[0096] The servo motor 111 drives the Z-axis lead screw 109 to rotate via the synchronous belt and the pulley, thereby moving the Z-axis slide 106 up and down along the vertical slide rail 107, thereby adjusting the height of the clamping assembly to adapt to steel sections of different specifications and sizes.

[0097] The driver 1 includes a horizontal slider installed on the bottom of the moving platform 101, a servo motor 116 and a lubrication wheel 118, and a travel gear 117 is installed at the output end of the servo motor 116;

[0098] A horizontal slide rail 113 and a horizontal rack 112 are installed on the top of the pushing bracket 100. The horizontal slide rail 113 and the horizontal slider are slidably matched, and the horizontal rack 112 and the travel gear 117 and the lubrication wheel 118 are meshed and matched.

When the movable clamping plate 103 fits tightly against the inner side of the wing plate, the output end of the hydraulic cylinder continues to output, and the fixed clamping plate 104 approaches the outer side of the wing plate and fits it. During the approaching process, the spring member 121 is compressed, and the push arm 102 and the Z-axis slide 106 are parallel.
