Description

Technical Field

[0001] The invention relates to the technical field of round steel processing, in particular to round steel cutting equipment with a feeding device. Background Art

[0002] Round steel refers to a solid long strip of steel with a circular cross-section. During production, processing and use, the round steel needs to be cut according to the needs of use so that the longer round steel can be cut into the required shorter length.

[0003] During the round steel cutting process, the round steel needs to be loaded, cut and unloaded. For example, patent publication number CN211966192U discloses a fixing device for a round steel cutting machine. Its structure mainly includes a cutting table and a cutting machine. The rear end of the cutting table is connected to a feeding table and a feeding mechanism. A set of relative clamping mounting shells and a clamping mechanism are installed on both sides of the cutting machine. The feeding mechanism located on the feeding table can transport the round steel on the feeding pulley to the set cutting position. The clamping mechanism can clamp and fix the round steel to be cut, so that the cut surface of the round steel is smoother.

[0004] The above device can realize the loading and cutting operations of round steel, but each time the round steel is cut, the round steel needs to be de-positioned, moved and re-positioned. When the length of the round steel cut each time is short, the round steel needs to be frequently moved and positioned, which makes the operation inconvenient and reduces the processing efficiency.

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0061] Example 1, please refer to the accompanying drawings, the present invention provides a technical solution:

[0062] A round steel cutting device with a feeding device, such as Figure 1 As shown, it includes a first base 100 and a second base 300 fixed to each other, and a feeding device and a cutting component are provided on the first base 100;

[0063] like Figure 2 As shown, the feeding device includes a base plate 102 and two support frames 101 symmetrically fixed between the base plate 102 and the first base 100. A support assembly is connected to the base plate 102 through multiple lifting hydraulic rods 105 evenly arranged. A limited conveying assembly is connected above the inner end of the support assembly, and a cutting assembly is arranged at the inner end of the base plate 102.

[0064] like Figure 3 As shown, a first adjustment assembly is provided on the top of the second base 300, and the first adjustment seat 301 and the movable seat 307 are connected through the first adjustment assembly, and a rectangular groove is provided in the middle position of the first adjustment seat 301 corresponding to the position of the movable seat 307, and the end of the rectangular groove close to the movable seat 307 is set to be open to expand the adjustable range of the movable seat 307, and the top of the first adjustment seat 301 is connected to two symmetrically arranged second adjustment seats 603 through the second adjustment assembly, and a vertical stop plate 306 is fixed to the top of the movable seat 307 through a vertical rod;

[0065] Two fixing frames 602 are symmetrically fixed on the top of the second adjustment seat 603. A rotating assembly is provided between the tops of the two fixing frames 602. A plurality of positioning assemblies are evenly arranged on each rotating assembly along the circumferential direction. A pushing assembly is provided on the fixing frame 602 near the end of the second adjustment seat 603, and the position of the pushing assembly corresponds to the position of one of the positioning assemblies.

[0066] An intermediate frame 800 is provided on the top of the second adjustment seat 603. A first bracket 801 is provided on the top of the intermediate frame 800, and an inclined second bracket 802 is provided on one side of the bottom. Separate drive components are provided on the first bracket 801 and the second bracket 802, and are connected to two of the positioning components via the separate drive components.

[0067] A blanking assembly is provided in the middle above the first adjustment seat 301 . The blanking assembly is located between the two rotating assemblies, and a double-sided cutting assembly is provided on one side of the upper portion of the blanking assembly.

[0068] When processing round steel, the round steel is placed on the support assembly on the feeding device, and the support assembly provides support for the round steel conveying process, and the position of the support assembly and its upper limit conveying assembly is adjusted by the lifting hydraulic rod 105, so that the limit conveying assembly and the support assembly are in close contact with the round steel and the position is adjusted so that the position of the round steel corresponds to the center of the positioning assembly at the top of the rotating assembly. Then, the round steel is moved toward the rotating assembly through the driving action of the limit conveying assembly, and passes through the positioning assemblies at the top positions of the two rotating assemblies. The end contacts the stop plate 306, and the initial cut-off position of the round steel is located at the cut-off assembly through the action of the stop plate 306, completing a round steel loading operation.

[0069] The separate driving assembly at the first bracket 801 is activated, so that it contacts the positioning assembly at the top of the rotating assembly and drives the positioning assembly to move, thereby clamping and positioning the round steel through the internal structure of the positioning assembly. Then, the cutting assembly is activated to perform the initial cutting process on the round steel.

[0070] After completing a cut, the rotating assembly drives multiple positioning assemblies and the round steel to rotate a certain angle, switching the position of the round steel. During each rotation, the positioning assemblies at adjacent positions move toward the top of the rotating assembly, so that the round steel gradually approaches the double-sided cutting assembly.

[0071] When the round steel passes through the double-sided cutting assembly, the middle section of the round steel is cut to divide the round steel into three equal sections. The middle section falls directly onto the unloading assembly for unloading. The remaining two sections of round steel move to the pushing assembly as the rotating assembly rotates intermittently and switches positions.

[0072] When the round steel moves to the pushing assembly, the separate driving assembly at the second bracket 802 causes the positioning assembly to move in the opposite direction, canceling the positioning effect on the round steel, and the pushing assembly pushes the round steel in the positioning assembly outward and drops it onto the unloading assembly for unloading operation.

[0073] The present invention arranges multiple positioning components on the rotating component, so that round steels at different positions can be simultaneously subjected to operations such as primary cutting, secondary cutting, pushing and unloading, thereby improving processing efficiency; and separate drive components are arranged at the top of the rotating component and the pushing component to realize the clamping positioning and cancellation positioning operations of the positioning components, making the positioning and unloading of round steels more convenient and quick.

[0074] The invention can perform primary cutting and secondary cutting on round steel, so that the round steel can be processed on both sides and cut into multiple shorter sections of round steel. Moreover, cutting and truncation can be performed simultaneously at different positions of the rotating assembly, so that the round steel can be cut more quickly.

[0075] The present invention can realize the position of the first adjustment seat 301, the movable seat 307 and the stop plate 306 by setting the first adjustment component and the second adjustment component so as to adjust the cutting length of the round steel, and adjust the position of the two second adjustment seats 603 and the rotating components and positioning components thereon through the second adjustment component so as to adjust the positioning position on the round steel according to the cutting position of the round steel, thereby improving the application range of the equipment and making the equipment more flexible to use.

[0076] Among them, Figure 10 As shown, the rotating assembly includes a central shaft 601 that is horizontally arranged and rotatably connected between the tops of two fixed frames 602, two parallel rotating ring plates 600 are fixed on the central shaft 601, and the positioning assembly is evenly arranged on the two rotating ring plates 600 along the circumferential direction, one end of the central shaft 601 extends out of the fixed frame 602 and is fixed with a third bevel gear 604, the bottom of the third bevel gear 604 is engaged with a fourth bevel gear 605, the fourth bevel gear 605 is connected to a motor, and the motor is fixedly connected to the fixed frame 602.

[0077] When cutting the positions of multiple positioning components and round steel, the central shaft 601 drives the rotating ring plate 600 and the multiple positioning components thereon to rotate through the drive of the motor and the transmission of the third bevel gear 604 and the fourth bevel gear 605, thereby realizing position switching, so as to perform operations such as truncation, double cutting, pushing and unloading on the round steel in turn.

[0078] Among them, Figure 11 、 Figure 12 As shown, the positioning assembly includes a first threaded cylinder 606 rotatably connected to two rotating ring plates 600 , two second threaded cylinders 702 symmetrically arranged in the first threaded cylinder 606 , and a positioning cylinder 700 located at the center of the two second threaded cylinders 702 ;

[0079] A third gear 607 is fixed to the middle of the first threaded barrel 606, and the third gear 607 is correspondingly connected to the separate drive assembly. The first threaded barrel 606 has threads on both sides with opposite rotation directions, which are respectively threadedly connected to the two second threaded barrels 702;

[0080] The outer end of the second threaded barrel 702 extends out of the first threaded barrel 606 and is symmetrically fixed with two end plates 703. Springs are connected between the end plates 703 and the rotating ring plate 600 on the corresponding side. A guide shaft 704 is fixed to the rotating ring plate 600 at a position corresponding to each end plate 703. The guide shaft 704 passes through the end plates 703 and is slidably connected to them.

[0081] The two ends of the positioning cylinder 700 extend out of the second threaded cylinder 702 and are fixed to the rotating ring plate 600. A plurality of positioning plates 705 are evenly arranged along the circumferential direction on the inner side of the positioning cylinder 700, and a plurality of notches are correspondingly provided on the side wall. The positioning plate 705 is symmetrically arranged on one side close to the notch and is rotatably connected to two push-pull rods 706, and a V-shaped groove is provided on the other side to facilitate clamping and positioning of the round steel section. The other ends of the two push-pull rods 706 pass through the notch and are rotatably connected to the inner walls of the two second threaded cylinders 702 respectively.

[0082] Among them, a tube end frame 701 is fixed on the outer side of the rotating ring plate 600 at the position corresponding to the positioning tube 700, and the two ends of the positioning tube 700 are fixedly connected to the tube end frame 701 on the corresponding side, and the end passes through and extends out of the tube end frame 701, and the fixed connection between the rotating ring plate 600 and the positioning tube 700 is realized through the tube end frame 701, and by reasonably setting the structure of the tube end frame 701, it is staggered with the structural position of the second threaded tube 702 and other structures.

[0083] When the positioning cylinder 700 and other structures move to the top of the rotating ring plate 600, the round steel is moved by the feeding device and enters the positioning cylinder 700 at the top of the two rotating ring plates 600, and the third gear 607 drives the first threaded cylinder 606 to rotate through the separate driving assembly at the corresponding position, and the second threaded cylinder 702 is limited and guided by the guide shaft 704 and the end plate 703. Under the action of the thread of the first threaded cylinder 606, the second threaded cylinder 702 can only move inward along the guide shaft 704, thereby driving the top of the push-pull rod 706 to move, and through the action of the push-pull rods 706 on both sides, the positioning plate 705 is moved toward the inner direction of the positioning cylinder 700, and then the round steel is clamped and fixed by the multiple positioning plates 705 moving at the same time, which is convenient for the cut-off operation and subsequent position switching.

[0084] When the round steel rotates and moves to the pushing assembly after being cut by the double-sided cutting assembly, the third gear 607 on the first threaded cylinder 606 is connected to the separate driving assembly, and the separate driving assembly causes the third gear 607 and the first threaded cylinder 606 to rotate in opposite directions, thereby causing the second threaded cylinder 702 to move outward, so that the positioning plate 705 is moved away from the round steel under the action of the push-pull rod 706, canceling the positioning effect, so that the round steel in the positioning cylinder 700 can be pushed for unloading under the action of the pushing assembly.

[0085] Among them, Figure 11 、 Figure 12 As shown, the separate drive assembly includes two symmetrically arranged telescopic hydraulic rods 803, the length direction of the telescopic hydraulic rods 803 is parallel to the radius direction of the rotating ring plate 600, and the telescopic hydraulic rods 803 in the two separate drive assemblies are respectively fixed on the corresponding first bracket 801 and second bracket 802, and a telescopic plate 804 is commonly fixed on one end of the two telescopic hydraulic rods 803 close to the rotating ring plate 600, and the telescopic plate 804 is rotatably connected to the fourth gear 805, and the fourth gear 805 is connected to the motor.

[0086] When the rotating assembly drives the positioning assembly to move to the first bracket 801, the round steel enters the corresponding positioning cylinder 700, and the telescopic plate 804 drives the fourth gear 805 to move downward through the telescopic hydraulic rod 803 on the first bracket 801, so that the fourth gear 805 is engaged with the third gear 607 on the first threaded cylinder 606, and then the first threaded cylinder 606 is rotated by the drive of the motor and the transmission of the third gear 607 and the fourth gear 805, thereby driving the structure in the positioning assembly to move, so that the positioning plate 705 clamps the round steel and positions it, and then the fourth gear 805 and other structures move back to their original position and disengage from the third gear 607 to avoid affecting subsequent rotation and position switching;

[0087] When the round steel passes through the double-sided cutting assembly and moves to the pushing assembly, the telescopic plate 804 and the fourth gear 805 on the second bracket 802 move toward the positioning cylinder 700 at the pushing assembly, and then the first threaded cylinder 606 is driven by the motor, the third gear 607 and the fourth gear 805 to rotate in the opposite direction, so that the positioning plate 705 is separated from the round steel and the positioning of the round steel is cancelled, so that the pushing assembly can push the round steel to perform the unloading operation.

[0088] Example 2: The structure of this example is basically the same as that of Example 1, except that Figure 7 As shown, the blanking assembly includes connecting frames 501 fixed on both sides of the middle of the second adjustment seat 603, and an inclined blanking plate 500 is commonly fixed on the top of the two connecting frames 501. A plurality of guide seats 503 are evenly fixed on the bottom of the blanking plate 500. Two guide plates 504 are symmetrically arranged and slidably connected in each guide seat 503. The outer end of the guide plate 504 extends out of the guide seat 503 and is fixed with a spring seat 505. A spring is connected between the spring seat 505 and the guide seat 503. An inclined guide plate 502 is commonly fixed on the top of the multiple spring seats 505 on the same side. The guide plate 502 and the blanking plate 500 are located on the same inclined surface.

[0089] like Figure 13As shown, the pushing assembly includes a mounting frame 901 fixed on the fixing frame 602, a horizontal pushing hydraulic rod 900 is fixed on the mounting frame 901, a cylindrical pushing block 902 is fixed to the inner end of the pushing hydraulic rod 900, and the position of the pushing block 902 corresponds to the center of the positioning assembly.

[0090] After the round steel passes through the double-sided cutting assembly, the middle section of the round steel falls onto the blanking plate 500 and rolls along the inclined blanking plate 500 for unloading. Then, the rotating assembly and the positioning assembly drive the remaining round steel to continue rotating to the pushing assembly. The positioning assembly is moved by the separate driving assembly and the round steel is released. Then, the pushing hydraulic rod 900 moves the pushing block 902 and pushes the round steel toward the guide plate 502 and the blanking plate 500, so that the round steel is separated from the positioning assembly, falls onto the guide plate 502 and the blanking plate 500, and rolls for unloading.

[0091] When the second adjustment seats 603 on both sides move and adjust their positions, the fixed frames 602 on the corresponding sides move accordingly and contact the guide plate 502. Under the joint action of the spring seat 505, the guide plate 504 and the spring, the guide plate 502 adjusts its position accordingly to adapt to the position of the rotating component.

[0092] Example 3: The structure of this embodiment is basically the same as that of Example 1, except that Figure 5 As shown, the first adjustment assembly includes two symmetrical and parallel first screws 302 rotatably connected to the top of the second base 300, the first screws 302 are close to the side of the second base 300, and the two sides of the first adjustment seat 301 are threadedly connected to the two first screws 302, the bottom middle of the second base 300 is rotatably connected to two symmetrical and parallel second screws 303, the movable seat 307 is threadedly connected to the two second screws 303, and the first adjustment seat 301 is provided with through holes at positions corresponding to the two second screws 303, as shown in FIG. Figure 6 As shown, a first gear 308 is fixed to one side of the second screw 303, and a second gear 309 is meshed between the two first gears 308. The second gear 309 is connected to a motor, and the motor is fixed to the end of the second base 300.

[0093] The second adjustment assembly includes a third screw 304 rotatably connected to both sides of the top of the first adjustment seat 301, one end of the third screw 304 is connected to a motor, the two side sections of the third screw 304 have opposite thread rotation directions, and the second adjustment seat 603 is simultaneously threadedly connected to the same side section of the two third screws 304.

[0094] When it is necessary to adjust the position of the first adjustment seat 301 and the movable seat 307, the two second screws 303 are rotated at the same time by the drive of the motor and the transmission of the first gear 308 and the second gear 309, and the first screw 302 on the corresponding side is rotated by the transmission of the first pulley 305, so that the first adjustment seat 301 and the movable seat 307 move at the same time, and by reasonably setting the thread rotation direction and thread spacing of the first screw 302 and the second screw 303, when the first adjustment seat 301 moves a certain distance to one side, the movable seat 307 moves twice the distance in the same direction, so that when adjusting the distance of the first adjustment seat 301 relative to the cutting assembly, the distance between the stop plate 306 and the first adjustment seat 301 always keeps moving with the distance between the first adjustment seat 301 and the cutting assembly, so that when the cut round steel is located between the cutting assembly and the stop plate 306, it is symmetrically located on the two rotating assemblies.

[0095] When adjusting the positions of the two second rotating assemblies, the third screw 304 is rotated by the motor drive, thereby moving the two second adjustment seats 603 inward or outward at the same time, thereby achieving position adjustment of the rotating assembly and the positioning assembly.

[0096] Example 4: The structure of this example is basically the same as that of Example 2, except that Figure 4 As shown, the cutting assembly includes two vertical movable hydraulic rods 108 symmetrically fixed to the top of the inner end of the base plate 102, and a movable frame 109 is fixed to the top of the two movable hydraulic rods 108. A first cutting knife 110 is rotatably connected to the movable frame 109, and a motor is connected to one side of the first cutting knife 110, and the motor is fixed to the movable frame 109. After the round steel is moved into place, the movable hydraulic rod 108 drives the first cutting knife 110 to move downward, and the first cutting knife 110 is rotated by the motor to cut the round steel.

A plurality of transmission grooves are correspondingly provided on the inner side wall of the transmission cylinder 404, and the transmission blocks are slidably connected to the transmission grooves. A first bevel gear 407 is fixed to the middle part of the transmission shaft 406, and a second bevel gear 408 is engaged with one side of the first bevel gear 407. The second bevel gear 408 is connected to a motor, and the motor is fixed on the connecting frame 501.

[0099] When it is necessary to adjust the distance between the two second cutting knives 400, that is, to adjust the cutting length of the middle section of the round steel, the hydraulic rod 401 is adjusted to move the knife holder plates 402 on both sides inward or outward at the same time, thereby driving the second cutting knives 400, the transmission cylinder 404 and the second pulley 403 to move, thereby achieving position adjustment and moving the transmission cylinder 404 along the transmission shaft 406. At the same time, the transmission cylinder 404 is always connected to the transmission shaft 406 through the transmission groove and the transmission block.

[0100] When the rotating assembly and the positioning assembly drive multiple round steels to move intermittently and pass through the second cutting knife 400, the second cutting knife 400 rotates under the drive of the motor, the transmission of the first bevel gear 407 and the second bevel gear 408, the transmission of the transmission cylinder 404 and the transmission shaft 406, and the transmission of the second pulley 403, and performs bilateral cutting on the passing round steels, and makes the middle section of the round steel fall onto the inclined blanking plate 500 for blanking. The remaining two are located on the corresponding rotating assembly so that they can subsequently move to the pushing assembly for pushing and blanking.

[0101] Example 5: The structure of this example is basically the same as that of Example 1, except that Figure 4 As shown, the support assembly includes a lifting groove 103 fixed to the top of multiple lifting hydraulic rods 105, and multiple support rollers 104 are evenly arranged and rotatably connected on the lifting groove 103 along the length direction, and a groove is provided around the middle of the roller surface of the support roller 104.

[0102] The position-limiting conveying assembly includes a lifting plate 200 located above the lifting groove 103.

An intermediate gear 106 is engaged between the first rack 107 and the second rack 201, and the intermediate gear 106 is rotatably connected to the bottom plate 102.

[0104] When feeding and conveying round steel, the round steel is supported by multiple support rollers 104, and the round steel is located in the middle of the support rollers 104 through the action of the grooves on the support rollers 104. Then, the lifting groove 103, the support rollers 104 and the round steel are moved upward by the action of the lifting hydraulic rod 105. At the same time, the lifting plate 200 drives the pressure roller 202 to move downward through the action of the first rack 107, the intermediate gear 106 and the second rack 201. Therefore, the round steel is limited by the close contact between the support rollers 104 and the pressure rollers 202 and the round steel. The multiple pressure rollers 202 are driven by the motor, the worm 204 and the multiple worm gears 203 to rotate simultaneously, drive and convey the round steel, and realize the feeding operation of the round steel.
