Description

Technical Field

[0001] The present invention relates to the technical field of punching and shearing equipment, and in particular to a sheet metal punching and shearing equipment based on office furniture processing. Background Art

[0002] Punching, also known as shearing or cutting, is a process widely used in industries such as metalworking, woodworking, and paper processing. It is primarily used to separate or form raw materials into predetermined shapes and sizes. Punching and shearing processes can be divided into two main categories: punching and shearing. In office furniture manufacturing, sheet metal punching and shearing equipment is a key component used to cut sheet metal into the desired size and shape, and is crucial for improving production efficiency and material utilization.

[0003] During the processing of sheet materials, punching and shearing equipment is needed to punch the sheet materials, such as punching various holes. The specifications of the sheet materials used for office furniture vary. The punching and shearing planes of existing punching and shearing equipment are generally fixed specifications. Therefore, when punching and shearing sheet materials that exceed the placement plane, it is often necessary to manually support the sheet materials, and then use the punching and shearing equipment to punch or cut the sheet materials. The method of manually supporting the sheet materials and performing mobile punching has the defects of inaccurate stamping accuracy and low stamping efficiency.

[0004] Based on this, it is necessary to design a sheet metal punching and shearing equipment based on office furniture processing, whose punching and shearing plane can be adaptively adjusted according to the specifications of the sheet metal. Summary of the Invention

[0005] The U-shaped support frame is provided on the bottom of the rotating support plate, and the U-shaped support frame slidably cooperates with the guide frames provided on both sides of the sliding support plate, and a limiting component for limiting the U-shaped support frame is provided on the U-shaped support frame so that the rotating support plate remains flush with the sliding support plate to adapt to material plates of different specifications.

[0006] Optionally, the limiting assembly includes a Q-shaped frame, a long protrusion, an inverted E-frame, a wedge-shaped block and a spring. A pair of Q-shaped frames are provided on the U-shaped frame below the rotating support plate. An inverted E-frame is slidably connected between the Q-shaped frames. A wedge-shaped block is connected to the top of the inverted E-frame. The inverted E-frame passes through the end of the Q-shaped frame and a spring is provided between the Q-shaped frame. A long protrusion is provided on the U-shaped support frame, and a limiting groove that is plugged into and cooperates with the wedge-shaped block is provided at the bottom of the long protrusion.

[0007] Optionally, the rotation angle of the rotating support plate is less than or equal to 90 degrees.

[0008] Optionally, an L-shaped limiting rod is provided on the outer wall of the U-shaped frame provided with the Q-shaped frame, which is engaged with the U-shaped support frame to fix the rotating support plate after rotation.

[0009] Optionally, a locking mechanism is provided on the base plate to lock the movement of the U-shaped frame, the locking mechanism including a base frame, a mounting block, an N-shaped limit block, a locking block and a spring. The base frame is symmetrically arranged on the base plate, and no less than two groups of mounting blocks are provided on the base frame, each group of mounting blocks consists of two mounting blocks, and each group of mounting blocks is slidably connected with an N-shaped limit block. A locking block is provided at a position on the U-shaped frame corresponding to the N-shaped limit block, and a locking groove is provided on the side of the locking block facing the N-shaped limit block. The side of the N-shaped limit block facing the locking block is conically arranged and can be locked into the locking groove of the locking block.

[0010] Optionally, it also includes a lower pressure frame, an inverted T-shaped rod and a spring three. The lower pressure frame is slidably provided at the bottom of the punching and shearing table through the inverted T-shaped rod. The lower pressure frame is arranged above the punching and shearing table. The lower pressure frame is fixedly connected to the punching and shearing assembly. A spring three is arranged between the end of the lower pressure frame and the bottom of the punching and shearing table. The spring three is wound on the inverted T-shaped rod.

[0011] Optionally, it also includes a W-shaped push plate, an H-frame, a top column, an I-shaped extrusion rod and an inclined extrusion block. The W-shaped push plate is slidably connected to the sliding support plate, and the top column is connected to the center of the W-shaped push plate. The top column passes through the sliding support plate and the punching and shearing table from top to bottom and then slides with the H-frame installed on the U-shaped frame. An inclined extrusion block is provided at the bottom of the top column, and an I-shaped extrusion rod is provided between the ends of adjacent N-shaped limit blocks away from the card block. The I-shaped extrusion rod is extruded and fitted with the inclined extrusion block.

[0012] Optionally, it also includes a baffle, a sliding rod and a spring four. A baffle is movably provided on the side of the rotating support plate away from the sliding support plate. The two ends of the baffle are connected with a sliding rod. The sliding rod is slidably connected to the side wall of the rotating support plate, and a spring four is wrapped around the sliding rod.

[0013] The beneficial effects of the present invention are: 1. By rotating the rotating support plate, the rotating support plate and the sliding support plate are made flush, thereby providing an effective punching and shearing plane for a sheet with a large area. By moving the U-shaped frame, the rotating support plate and the sliding support plate are driven to move horizontally along the punching and shearing table, thereby moving the sheet to the bottom of the punching and shearing assembly, providing convenience for the punching and shearing assembly to perform precise punching on the sheet, thereby realizing the function of moving and punching the sheet.

[0014] 2. The U-shaped frame is limited by the cooperation of the clamping block and the N-shaped limit block, so that the sliding support plate and the rotating support plate moved under the punching and shearing assembly are limited. When the punching and shearing assembly moves down, the lower pressure frame moves down to press the material plate, and the punching and shearing assembly can perform precise punching and shearing operations on the material plate, thereby ensuring the accuracy of punching and shearing.

DETAILED DESCRIPTION

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0027] Example: A sheet metal punching and shearing device based on office furniture processing, such as Figure 1 、 Figure 2 and Figure 3As shown, it includes a bottom plate 1, a punching and shearing table 2, a punching and shearing assembly 21, a horizontal plate 101, a U-shaped frame 3, a sliding support plate 4, a rotating support plate 5, a Q-shaped frame 31, a guide frame 41, a U-shaped support frame 51, a long protrusion 52, an inverted E frame 6, a wedge block 60 and a spring 61.

A rotating support plate 5 is provided on the front side of the sliding support plate 4. The rotation angle of the rotating support plate 5 is less than or equal to 90 degrees. When the rotating support plate 5 is rotated and expanded to be flush with the sliding support plate 4, the rotating support plate 5 and the sliding support plate 4 together constitute an expanded material sheet placement plane. At this time, the expanded material sheet placement plane can adapt to large-sized material sheets. The expanded material sheet placement plane replaces manual support of the material sheet, which is more stable. A pair of Q-shaped frames 31 are provided on the front U-shaped frame 3, and an inverted E-frame 6 is slidably connected between the Q-shaped frames 31. A wedge block 60 is connected to the top of the inverted E-frame 6, and the inverted E-frame 6 passes through the Q-shaped frame 31. A spring 61 is provided between the end portion and the Q-shaped frame 31, and the two ends of the spring 61 are respectively connected to the ends of the Q-shaped frame 31 and the inverted E frame 6. The spring 61 is a compression spring, and a U-shaped support frame 51 is provided at the bottom of the rotating support plate 5. The U-shaped support frame 51 slides with the guide frames 41 provided on both sides of the sliding support plate 4. A long strip protrusion 52 is provided on the U-shaped support frame 51, and a limiting groove is provided at the bottom of the long strip protrusion 52 to engage with the wedge block 60. The left and right outer walls of the front U-shaped frame 3 are provided with L-shaped limiting rods 7 that are engaged with the U-shaped support frame 51 to fix the rotating support plate 5 after rotation. After the wedge block 60 is inserted into the limiting groove at the bottom of the long strip protrusion 52, the inverted E frame 6 is the U-shaped support frame 5 When the U-shaped support frame 51 is in the same position as the guide frame 41, the U-shaped support frame 51 is in the same position as the guide frame 41. When the U-shaped support frame 5 is in the same position as the guide frame 41, the U-shaped support frame 51 is in the same position as the guide frame 41. When the U-shaped support frame 5 is in the same position as the guide frame 41, the U-shaped support frame 51 is in the same position as the guide frame 41. When the U-shaped support frame 5 is in the same position as the guide frame 41, the L-shaped limit rod 7 is inserted into the U-shaped support frame 5 to fix the U-shaped support frame 51.

[0028] like Figure 4 、 Figure 5 and Figure 6 As shown, a positioning mechanism 8 for positioning the U-shaped frame 3 is provided on the bottom plate 1. The positioning mechanism 8 includes a bottom frame 81, a mounting block 82, an n-shaped limiting block 83, a blocking block 84 and a spring 85. The bottom plate 1 is symmetrically provided with a bottom frame 81. Three groups of mounting blocks 82 are provided on the bottom frame 81. The number of mounting blocks 82 can also be increased according to the design. Each group of mounting blocks 82 consists of two mounting blocks 82. Each group of mounting blocks 82 is slidably connected with an n-shaped limiting block 83. A blocking block 84 is provided at a position on the U-shaped frame 3 that is adapted to the n-shaped limiting block 83. A card slot is provided on the card block 84 toward one side of the n-shaped limiting block 83. The n-shaped limiting block 83 is moved toward One side of the block 84 is conically set and can be inserted into the slot of the block 84. The slot is conically set, and the end of the N-shaped limit block 83 facing the block 84 is conically set. The conical end of the N-shaped limit block 83 and the conical slot on the block 84 slide together. This setting facilitates the sliding insertion of the N-shaped limit block 83 into the slot of the block 84. At the same time, under the action of the horizontal pushing force on the block 84, the slot on the block 84 is also easily separated from the conical end of the N-shaped limit block 83, so that the U-shaped frame 3 is limited when the material plate is punched. When the material plate needs to be moved to facilitate the next punching operation, the limit on the U-shaped frame 3 can be easily released.

[0029] like Figure 7 and Figure 8 As shown, it also includes a lower press frame 9, an inverted T-shaped rod 91 and a spring three 92. The bottom of the punching and shearing table 2 is slidably provided with a lower press frame 9 through the inverted T-shaped rod 91. The lower press frame 9 is arranged above the punching and shearing table 2. The lower press frame 9 is fixedly connected to the punching and shearing assembly 21. The middle of the lower press frame 9 is hollowed out. The punching and shearing assembly 21 can pass through the lower press frame 9 to punch the material plate. A spring three 92 is provided between the end of the lower press frame 9 and the bottom of the punching and shearing table 2. The spring three 92 is wound on the inverted T-shaped rod 91. The two ends of the spring three 92 are respectively connected to the lower press frame 9 and the punching and shearing table 2. The spring three 92 is a tension spring. The initial state of the spring three 92 is as shown in FIG. Figure 8 shown.

[0030] like Figure 1 and Figure 9As shown, it also includes a Wang-shaped push plate 10, an H frame 1001, a top column 1002, an I-shaped extrusion rod 1003 and an inclined extrusion block 1004. The sliding support plate 4 is slidably connected to the Wang-shaped push plate 10. Under normal circumstances, the Wang-shaped push plate 10 is placed in the groove at the top of the sliding support plate 4. The Wang-shaped push plate 10 is flush with the sliding support plate 4. The center of the Wang-shaped push plate 10 is connected with a top column 1002. The top column 1002 passes through the sliding support plate 4 and the punching and shearing table 2 from top to bottom and then slides with the H frame 1001 installed on the U-shaped frame 3. The bottom of the top column 1002 is set There is an inclined extrusion block 1004, and an I-shaped extrusion rod 1003 is arranged between the ends of adjacent N-shaped limit blocks 83 away from the blocking block 84. The I-shaped extrusion rod 1003 is extruded and matched with the inclined extrusion block 1004. When the I-shaped extrusion rod 1003 squeezes the inclined extrusion block 1004, the inclined extrusion block 1004 pushes the top column 1002 upward, and the top column 1002 pushes the Wang-shaped push plate 10 upward, and the Wang-shaped push plate 10 pushes the material plate upward, thereby avoiding adhesion between the punched holes and the sliding support plate 4 after the material plate is punched, and at the same time, it also provides convenience for unloading the material plate.

[0031] like Figure 1 and Figure 10 As shown, it also includes a baffle 11, a sliding rod 111 and a spring four 112. A baffle 11 is movably provided on the side of the rotating support plate 5 away from the sliding support plate 4. The two ends of the baffle 11 are connected to the sliding rod 111. The sliding rod 111 is slidably connected to the side wall of the rotating support plate 5. The sliding rod 111 is wound around the spring four 112. The baffle 11 is used to block the material plate on the sliding support plate 4 and the rotating support plate 5. At the same time, the baffle 11 is used to fix the material plate whose area exceeds the plane constructed by the sliding support plate 4 and the rotating support plate 5, thereby providing a guarantee for the punching operation of large-sized material plates.

[0032] When in use, the rotating support plate 5 is rotated upwards to be flush with the sliding support plate 4 (eg Figure 1When the support plate 5 is rotated upward, the U-shaped support frame 51 moves forward along the guide frame 41. When the long protrusion 52 contacts the inverted E frame 6, the long protrusion 52 squeezes the inverted E frame 6, and the inverted E frame 6 moves downward along the Q-shaped frame 31 and squeezes the spring 1 61. When the limiting groove at the bottom of the long protrusion 52 is close to the wedge block 60, under the action of the elastic force of the spring 1 61, the wedge block 60 is inserted into the limiting groove at the bottom of the long protrusion 52 along the inclined surface of the limiting groove at the bottom of the long protrusion 52, thereby The support frame 51 is fixed to achieve the state that the rotating support plate 5 and the sliding support plate 4 are flush with each other; the material plate can be placed on the placement plane constructed by the rotating support plate 5 and the sliding support plate 4, and by pushing the U-shaped frame 3 from left to right, the rotating support plate 5 and the sliding support plate 4 slide horizontally along the punching and shearing table 2, and when the block 84 moves with the U-shaped frame 3, the slot on the block 84 is engaged with the conical end of the top of the n-shaped limit block 83, thereby limiting the U-shaped frame 3, and the punching and shearing assembly 21 can punch and shear the material plate. When the punching and shearing assembly 21 is moved upward, the spring 3 92 is reset, and the lower pressure frame 9 moves upward away from the material sheet; when the U-shaped frame 3 moves, the clamping block 84 moves horizontally and squeezes the conical end of the N-shaped limit block 83, so that the conical end of the N-shaped limit block 83 slides out of the clamping groove of the clamping block 84. When the N-shaped limit block 83 moves in the direction away from the blocking block 84, the N-shaped limit block 83 drives the I-shaped extrusion rod 1003 to approach the inclined extrusion block 1004 and squeezes the inclined extrusion block 1004. After the inclined extrusion block 1004 is squeezed, the inclined extrusion block 1004 drives the push column 1002 to move upward, thereby pushing the Wang-shaped push plate 10 upward, thereby pushing the material plate on the sliding support plate 4 upward, avoiding the material plate punching cut and the sliding support plate 4 from sticking, and providing convenience for subsequent material plate unloading.
