Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to sheet metal cutting equipment used for hardware processing of hardware products. Background Technology

[0002] Hardware refers to five metals: gold, silver, copper, iron, and tin. These metals can be processed into metal parts such as knives and swords. Current hardware processing requires cutting sheet metal to facilitate subsequent processing.

[0003] When existing cutting equipment needs to replace the saw blade, it is usually necessary to first remove the fixing bolts one by one with a wrench, remove the old saw blade, then calibrate the installation position of the new saw blade, and finally retighten the bolts. The whole process relies on the operator's experience to ensure that the saw blade is centered. Each replacement is time-consuming and labor-intensive. In hardware processing scenarios, it is often necessary to switch saw blades according to the material of the sheet metal. Frequent replacements result in a high proportion of equipment downtime, which may reduce the operating efficiency of the cutting equipment. Utility Model Content

The outer wall of the L-shaped connecting rod is slidably fitted to the inner wall of the square groove.

The bottom of the C-shaped connecting plate is rotatably connected to the connecting base. The inner wall of the arc groove is slidably fitted to the outer wall of the right fulcrum. The inner wall of the push plate is slidably fitted to the outer wall of the limiting post.

[0009] As a preferred technical solution of this utility model: the cutting assembly includes a second motor mounted on the top of a guide block, a connecting box fixedly sleeved on the outer edge of the output shaft of the second motor, a transverse sliding groove and a longitudinal sliding groove respectively opened on the top of the connecting box, a threaded rod provided in the inner cavity of the connecting box, a square block fixedly installed on the inner wall of the connecting box, a rotating shaft fixedly installed on the top of the square block, a stop plate rotatably sleeved on the outer wall of the rotating shaft, a transverse slider threadedly connected to the outer wall of the threaded rod, a transverse pin fixedly installed on the top of the transverse slider, a first connecting rod provided on the outer wall of the transverse slider, one end of a second connecting rod rotatably connected to the outer wall of the stop plate, a longitudinal slider rotatably connected to the other end of the second connecting rod, a longitudinal pin fixedly installed on the top of the longitudinal slider, a cutting saw provided on the outer wall of the connecting box, a connecting shaft fixedly installed on the outer wall of the cutting saw, and a slot opened on the outer wall of the connecting shaft.

[0010] As a preferred technical solution of this utility model: one end of the threaded rod is constructed with a positive thread, and the other end is constructed with a reverse thread. The transverse groove, transverse slider, transverse pin, and first connecting rod are considered as a set of movable components, and there are two sets of such movable components, which are arranged symmetrically in the transverse direction with the abutment as the center. One end of each of the two first connecting rods is rotatably connected to the outer wall of the transverse slider, and the other end is rotatably connected to the bottom of the abutment. The outer walls of the two transverse sliders are fitted and slidably disposed in contact with the inner walls of the two transverse grooves.

The inner wall of the second connecting rod has an insertion hole, and the inner wall of the insertion hole is adapted to the shape of the outer wall of the connecting shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This sheet metal cutting equipment for hardware processing utilizes an external electric wrench to rotate a threaded rod, causing the threaded rod to simultaneously drive two sets of transverse sliders to slide in opposite directions, disengaging the transverse pins from their slots. Simultaneously, the rotating abutment plate drives the longitudinal slider to slide, disengaging the longitudinal pins in sync. This shortens the time required to change the cutting saw. Reversing the threaded rod allows the transverse and longitudinal pins to be inserted into their slots simultaneously, providing dual locking to prevent the cutting saw from loosening during high-speed rotation. This effectively avoids saw blade misalignment caused by vibration when using a single bolt for fixing.

[0012] 2. This sheet metal cutting equipment for hardware processing utilizes a cylinder to drive the push plate displacement. The L-shaped connecting rod rotates around the left fulcrum, driving the first flexible push head to push the sheet metal towards the center. Simultaneously, the C-shaped connecting plate deflects by fitting the right fulcrum through the arc groove, and the second flexible push head presses against the top of the sheet metal, forming bidirectional synchronous positioning. This reduces the displacement deviation caused by the rigid contact between the cutting saw and the sheet metal during the cutting operation, thereby improving the efficiency of the sheet metal cutting operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 A sheet metal cutting device for hardware processing includes a support platform 1, a placement platform 2 and a cutting platform 3 respectively set on the top of the support platform 1, an inclined plate 4 fixedly installed on the outer wall of the support platform 1, a square groove 5 opened on the top of the placement platform 2, a limit post 6 set on the bottom of the placement platform 2, a centering and positioning component 7 set on the bottom of the placement platform 2, a guide rod 8 fixedly installed on the bottom of the cutting platform 3, a first motor 13 fixedly installed on the outer wall of the support platform 1, a coupling 10 fixedly sleeved on the outer edge of the output shaft of the first motor 13, a lead screw 11 fixedly sleeved on the inner wall of the coupling 10, a guide block 12 threadedly connected to the outer wall of the lead screw 11, and a cutting component 9 set on the top of the guide block 12; In the above structure, the plate is first placed on top of the placement platform 2 and the cutting platform 3. At this time, the plate on the top of the placement platform 2 is positioned by operating the cutting component 9, so that the plate is in a fixed state. Then, the part reserved for processing on the top of the cutting platform 3 is started by starting the first motor 13. The outer edge of the output shaft of the first motor 13 drives the lead screw 11 and the guide block 12 to slide along the inner wall of the guide rod 8 through its coupling 10. At this time, the cutting component 9 on the top of the guide block 12 will cut the part reserved on the top of the plate of the cutting platform 3 accordingly.

[0017] In a preferred embodiment: there are two guide rods 8, and both guide rods 8 are disposed on both sides of the outer wall of the guide block 12, and the outer wall of the guide block 12 is slidably disposed in contact with the inner wall of the two guide rods 8; In the above structure, by starting the first motor 13, the outer edge of the output shaft of the first motor 13 drives the lead screw 11 to rotate through the coupling 10. The rotating lead screw 11 drives the guide block 12 to slide laterally along the guide rods 8 set on both sides of the outer wall, so that the cutting component 9 set on the top of the guide block 12 will perform the operation on the part of the plate that needs to be cut.

[0018] In a preferred embodiment: the centering and positioning component 7 includes a cylinder 701 fixedly installed at the bottom of the support platform 1, a push plate 702 fixedly installed at the telescopic end of the cylinder 701, a fisheye connector 703 and a connecting base 708 fixedly mounted on the top of the push plate 702, a left fulcrum 705 and a right fulcrum 709 fixedly installed on the outer wall of the support platform 1, an L-shaped connecting rod 706 rotatably connected to the outer wall of the left fulcrum 705, a first flexible push head 707 fixedly installed on the top of the L-shaped connecting rod 706, a C-shaped connecting plate 711 provided on the outer wall of the right fulcrum 709, an arc groove 710 opened on the outer wall of the C-shaped connecting plate 711, a second flexible push head 712 fixedly installed on the top of the C-shaped connecting plate 711, a spring 713 provided on the outer wall of the inclined plate 4, and a connecting plate body 704 provided on the outer wall of the fisheye connector 703. In a preferred embodiment: one end of the connecting plate body 704 is rotatably connected to the L-shaped connecting rod 706, and the other end is rotatably connected to the fisheye connector 703. The outer wall of the L-shaped connecting rod 706 is slidably fitted against the inner wall of the square groove 5. One end of the spring 713 overlaps with the outer wall of the inclined plate 4, and the other end overlaps with the bottom of the L-shaped connecting rod 706. The bottom of the C-shaped connecting plate 711 is rotatably connected to the connecting base 708. The inner wall of the arc groove 710 is slidably fitted against the outer wall of the right fulcrum 709. The inner wall of the push plate 702 is slidably fitted against the outer wall of the limiting post 6. In the above structure, by activating cylinder 701, the telescopic end of cylinder 701 drives push plate 702 to slide downward along the inner wall of limit post 6. The sliding push plate 702 simultaneously drives fisheye connector 703 and connecting base 708 to move synchronously. During this movement, fisheye connector 703 connects to L-shaped connecting rod 706 via connecting plate body 704. L-shaped connecting rod 706 rotates around the left fulcrum 705 along the inner wall of square groove 5 under the displacement of fisheye connector 703. This rotation simultaneously drives the first flexible push head 707 at the top to rotate, pushing the plate at the top of the placement platform 2 towards the center. Simultaneously, the rotation of L-shaped connecting rod 706 also compresses spring 713. Furthermore, as connecting base 708 moves downward, it... The C-shaped connecting plate 711 connected to it will move downwards. At this time, the C-shaped connecting plate 711 will move by fitting the right fulcrum 709 through the arc groove 710. The C-shaped connecting plate 711 will simultaneously move the second flexible push head 712 downwards, so that the bottom of the second flexible push head 712 will contact the top of the plate, thus positioning the plate in the middle. When it is necessary to release the positioning, it will move upwards through the telescopic end of the cylinder 701. When the push plate 702 moves upwards, the C-shaped connecting plate 711 will simultaneously move the second flexible push head 712 upwards under the upward movement of the connecting base 708, thus releasing the positioning of the plate. Then, the L-shaped connecting rod 706 will be in a tense state under the upward movement of the fisheye connector 703 and will be reset to the initial state by the rebound of the spring 713. At this time, the plate is in a state of no positioning, so that the processed plate can be removed.

[0019] In a preferred embodiment: the cutting assembly 9 includes a second motor 901 mounted on the top of the guide block 12. A connecting box 902 is fixedly sleeved around the outer edge of the output shaft of the second motor 901. The top of the connecting box 902 is provided with a transverse groove 903 and a longitudinal groove 904. A threaded rod 905 is provided inside the connecting box 902. A square block 906 is fixedly mounted on the inner wall of the connecting box 902. A rotating shaft 907 is fixedly mounted on the top of the square block 906. A stop plate 908 is rotatably sleeved on the outer wall of the rotating shaft 907. The outer wall of the threaded rod 905 is threaded... A horizontal slider 909 is connected, and a horizontal pin 910 is fixedly installed on the top of the horizontal slider 909. A first connecting rod 911 is provided on the outer wall of the horizontal slider 909. One end of a second connecting rod 912 is rotatably connected to the outer wall of the abutment plate 908. The other end of the second connecting rod 912 is rotatably connected to a vertical slider 913. A vertical pin 914 is fixedly installed on the top of the vertical slider 913. A cutting saw 915 is provided on the outer wall of the connecting box 902. A connecting shaft 916 is fixedly installed on the outer wall of the cutting saw 915. A slot 917 is opened on the outer wall of the connecting shaft 916. In a preferred embodiment: one end of the threaded rod 905 is constructed with a forward thread, and the other end is constructed with a reverse thread. The transverse groove 903, the transverse slider 909, the transverse pin 910, and the first connecting rod 911 are considered as a set of movable components, and there are two sets of such movable components, which are arranged laterally symmetrically with the abutment plate 908 as the center. One end of each of the two first connecting rods 911 is rotatably connected to the outer wall of the transverse slider 909, and the other end is rotatably connected to the bottom of the abutment plate 908. The outer walls of the two transverse sliders 909 are slidably fitted against the inner walls of the two transverse grooves 903. The outer wall of the transverse pin 910 is adapted to the inner wall of the slot 917. The longitudinal slide 904, the second connecting rod 912, the longitudinal slider 913 and the longitudinal pin 914 are regarded as a set of movable components, and there are two sets of such movable components. They are arranged longitudinally symmetrically with the abutment 908 as the center. The outer walls of the two longitudinal sliders 913 are fitted and slidably disposed with the inner walls of the two longitudinal slides 904. The outer walls of the two longitudinal pins 914 are adapted to the inner wall of the slot 917. The inner wall of the second connecting rod 912 has a insertion hole, and the inner wall of the insertion hole is adapted to the shape of the outer wall of the connecting shaft 916. In the above structure, by rotating the threaded rod 905 with an external electric wrench, the forward thread at one end and the reverse thread at the other end of the threaded rod 905 rotate synchronously. This rotation causes two transverse sliders 909, which are symmetrically arranged laterally around the abutment plate 908, to slide in opposite directions along the inner wall of the transverse groove 903. At this time, the two sliding transverse sliders 909 synchronously drive the transverse pins 910 fixed at the top to move in the same direction. The two transverse pins 910 then withdraw from the inner cavity of their corresponding slots 917. Simultaneously, as the two transverse sliders 909 slide in opposite directions, they synchronously drive one end of the first connecting rod 911 connected to them to extend. This causes the abutment plate 908, connected to the other end of the two first connecting rods 911, to rotate around the pivot 907 under the extension. At this time, the rotating abutment plate... 908 will synchronously push the two longitudinally connected second connecting rods 912 relative to each other, causing the two longitudinal sliders 913 to slide in opposite directions along the longitudinal groove 904. At this time, the two longitudinal pins 914 will also synchronously exit the inner cavity of their corresponding slots 917 under the sliding of the longitudinal sliders 913. At this time, the fixation between the connecting box 902 and the cutting saw 915 is released, allowing the cutting saw 915 to be taken out through the insertion hole opened on the inner wall of the connecting box 902 via the displacement slot 917. Secondly, when it is necessary to install and use a new cutting saw 915, the two transverse sliders 909 can be slid relative to each other by reversing the threaded rod 905. The synchronous abutment 908 drives the two longitudinal sliders 913 to slide relative to each other, so that the transverse pins 910 and the longitudinal pins 914 are inserted into the inner cavity of their corresponding slots 917 in sequence, thereby achieving their fixation.

[0020] Working Principle: The operator first places the plate to be cut on the top of the placement platform 2 and cutting platform 3 of the equipment. Then, by activating cylinder 701, the telescopic end of cylinder 701 drives push plate 702 to slide downwards along the inner wall of limit post 6. The sliding push plate 702 simultaneously drives fisheye connector 703 and connecting base 708 to move synchronously. During this movement, fisheye connector 703 connects to L-shaped connecting rod 706 via connecting plate body 704. Under the displacement of fisheye connector 703, L-shaped connecting rod 706 rotates around the left fulcrum 705 along the inner wall of square groove 5. Simultaneously, L-shaped connecting rod 706 drives the first flexible push head 707 at the top to rotate. When the first flexible push head 707 rotates, it pushes the plate on the top of placement platform 2 towards the center. Simultaneously, the rotation of L-shaped connecting rod 706 also compresses spring 713. Furthermore, when connecting base 708 moves downwards... The connecting base 708 will cause the bottom of the C-shaped connecting plate 711 connected to it to move downward. At this time, the C-shaped connecting plate 711 will move by fitting the right support point 709 through the arc groove 710. At this time, the C-shaped connecting plate 711 will simultaneously drive the second flexible push head 712 to move downward, so that the bottom of the second flexible push head 712 will contact the top of the plate, thereby positioning the plate in the middle. Then, the second motor 901 is started, and the outer edge of the output shaft of the second motor 901 drives the connecting box 902 and the cutting saw 915 fixed on the outer wall of the connecting box 902 to rotate synchronously. Then, the first motor 13 is started, and the outer edge of the output shaft of the first motor 13 drives the lead screw 11 to rotate through the coupling 10. The rotating lead screw 11 drives the guide block 12 to slide laterally along the guide rods 8 set on both sides of the outer wall. The rotating cutting saw 915 cuts the plate on the top of the cutting platform 3 under the lateral displacement of the guide block 12. Simultaneously, after the cutting operation is completed, the plate is moved upward through the telescopic end of the cylinder 701. When the push plate 702 moves upward, the C-shaped connecting plate 711 moves upward in sync with the upward movement of the connecting base 708, causing the second flexible push head 712 to move upward, thus releasing the positioning of the plate. Then, the L-shaped connecting rod 706, under the upward movement of the fisheye connector 703, will be in a taut state and return to its initial state through the rebound of the spring 713. At this time, the plate is in a state of no positioning, and then the plate is removed. When it is necessary to replace the cutting saw 915, the threaded rod 905 can be rotated using an external electric wrench. This causes the forward thread at one end of the threaded rod 905 and the reverse thread at the other end to rotate synchronously. This rotation will cause two transverse sliders 909, which are symmetrically arranged laterally around the abutment plate 908, to slide in opposite directions along the inner wall of the transverse groove 903. At this time, the two sliding transverse sliders 909 will synchronously drive the transverse pin 910 fixed at the top to move in the same direction. The transverse pin 910 will relatively disengage from the inner cavity of the corresponding slot 917. At the same time, when the two transverse sliders 909 slide in opposite directions, they will synchronously drive one end of the first connecting rod 911 connected to it to extend. The other end of the two first connecting rods 911 will be connected to the abutment 908, which will rotate around the pivot 907 under its extension. At this time, the rotating abutment 908 will synchronously push the two longitudinally connected second connecting rods 912 to push the two longitudinal sliders 913 to slide in opposite directions along the longitudinal groove 904. At this time, the two longitudinal pins 914 will also synchronously disengage from the inner cavity of the corresponding slot 917 under the sliding of the longitudinal sliders 913. At this time, the fixation between the connecting box 902 and the cutting saw 915 is released, so that the cutting saw 915 can be taken out through the displacement slot 917 and inserted into the insertion hole opened in the inner wall of the connecting box 902. Then, when a new cutting saw 915 needs to be installed, the installation of the cutting saw 915 can be achieved by performing the above reverse operation, thereby effectively shortening the replacement time of the cutting saw 915.
