Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a clamping structure for bending machine production. Background Technology

[0002] A bending machine bends metal sheets or profiles into the desired shape. During the bending process, a reliable clamping structure is crucial to ensure processing accuracy and quality, as well as the safety of operators. The clamping structure of a bending machine is relatively simple.

[0003] Existing bending machine clamping structures typically use rigid metal clamps that directly contact the sheet metal when clamping and fixing it. When the clamping force of the clamps exceeds a certain range, it is easy to create deep indentations on the surface of soft materials such as stainless steel, causing damage to the surface of the sheet metal after the bending machine has finished processing it, thus affecting the efficiency of sheet metal use. Therefore, we have introduced a clamping structure for bending machine production. Utility Model Content

[0014] 1. The clamping structure used in this bending machine, through the cooperation of a double-ended lead screw, connecting rod one, turntable, and connecting rod two, achieves synchronous reverse movement of sliding rod one and sliding rod two. At the same time, when sliding rod one and sliding rod two move in opposite directions, the one-way valve compresses, transmitting its gas through the air pipe to the air bladder. Before the clamp contacts the sheet metal, the air bladder forms a thick gas buffer layer, ensuring uniform pressure distribution on the contact surface between the air bladder and the sheet metal. This eliminates surface scratches caused by rigid clamping in existing equipment. Furthermore, the air bladder pressure can be adjusted to accommodate materials with different yield strengths, such as stainless steel, aluminum alloy, and copper plates, as the clamp moves, thereby improving the applicability of the equipment.

[0015] 2. The clamping structure used in this bending machine production, by pulling the pull rod, causes the pin, spring and wire rope to separate the outer wall of the pin from the inner wall of the slot, thereby realizing the disassembly and separation of the mounting block, machine body and clamping components and bending machine body. This facilitates convenient disassembly and maintenance of the clamping components and machine body, thus avoiding the time-consuming phenomenon of disassembling multiple parts in existing equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1 - Figure 6 A clamping structure for bending machine production includes a bending machine body 1, a base plate 2 fixedly installed on the outer wall of the bending machine body 1, a machine body 3 on the outer wall of the base plate 2, an mounting box 11 fixedly assembled on the outer wall of the base plate 2, square groove 12, sliding groove 14 and square groove 15 respectively opened on the inner wall of the mounting box 11, a connecting component 13 is provided in the inner cavity of square groove 15, a straight groove 4 is opened on the top of the machine body 3, a slider 5 is slidably connected to the inner wall of the straight groove 4, a placement platform 6 and a mounting block 7 are fixedly installed on the outer wall of the slider 5, a slot 8 is opened on the outer wall of the mounting block 7, a straight groove 9 is opened on the top of the placement platform 6, and a clamping component 10 is provided in the inner cavity of the placement platform 6.

[0027] The clamping assembly 10 includes a motor 101, a double-ended lead screw 102 fixedly sleeved on the outer edge of the output shaft of the motor 101, a rotating shaft 108 rotatably connected to the inner wall of the placement platform 6, a turntable 104 rotatably connected to the outer wall of the rotating shaft 108, a connecting rod 103 rotatably connected to the outer wall of the turntable 104, a sliding rod 106 rotatably connected to the other end of the connecting rod 103, a connecting rod 105 rotatably connected to the outer wall of the turntable 104, a sliding rod 107 rotatably connected to the other end of the connecting rod 105, a corrugated hose 109 provided on the inner wall of the straight groove 9, a one-way valve 110 provided on the outer wall of the corrugated hose 109, an air pipe 111 provided on the outer wall of the corrugated hose 109, a clamp 112 provided on the top of the sliding rod 106, and an airbag 113 provided on the inner wall of the clamp 112.

[0028] In the above structure, by setting the airbag 113, when the clamp 112 clamps and approaches the plate, the airbag 113 will be inflated, so that the inflated surface of the airbag 113 will extend to fit against the surface of the plate, thereby achieving the fixation of the plate.

[0029] In a preferred embodiment: the connecting assembly 13 includes a sleeve 131, the inner cavity of the sleeve 131 has a pin 132 and a spring 133 respectively, one end of a steel wire rope 134 is fixedly connected to the outer wall of the pin 132, the other end of the steel wire rope 134 is fixedly connected to a pull rod 136, and a roller 135 is rotatably connected to the inner wall of the square groove 15.

[0030] In a preferred embodiment: the sleeve 131, pin 132, spring 133, wire rope 134 and roller 135 are regarded as a movable component, and the movable component is respectively arranged on both sides of the inner wall of the square groove 15. The spring 133 is located at the bottom of the pin 132, and the two ends of the pin 132 overlap with the outer wall of the pin 132 and the inner wall of the sleeve 131 respectively. The outer wall of the pin 132 fits against the inner wall of the sleeve 131, and the diameter of the pin 132 is larger than the opening diameter of the sleeve 131. The outer wall of the pin 132 has the same shape as the inner wall of the slot 8, and the outer wall of the pin 132 is adapted to fit the inner wall of the slot 8. The outer wall of the pull rod 136 has the same shape as the inner wall of the slide groove 14, and the outer wall of the pull rod 136 is fitted and slidably fitted against the inner wall of the slide groove 14.

[0031] In the above structure, by setting up the pin 132, spring 133 and wire rope 134, when the pull rod 136 is pulled, the pull rod 136 slides along the inner wall of the slide groove 14, causing one end of the wire rope 134 to extend outward. The other end of the wire rope 134 pulls the spring 133 to slide along the inner wall of the sleeve 131. When the pin 132 slides, the spring 133 is compressed under the pressure of the pin 132, causing the outer wall of the pin 132 to separate from the inner wall of the slot 8, thereby realizing the disassembly of its mounting block 7. At the same time, by releasing the pull rod 136, the pin 132 is reset by the rebound of the spring 133. The wire rope 134 is reset by the reset of the pin 132, pulling the pull rod 136 to reset. Thus, another set of movable components set on the inner wall of the square slot 15 can achieve synchronous operation through the same operation.

[0032] In a preferred embodiment: the outer wall of the mounting block 7 has the same shape as the inner wall of the square groove 12, and the outer wall of the mounting block 7 is adapted to the inner wall of the square groove 12.

[0033] In the above structure, by setting the mounting block 7 and the square groove 12, when the mounting block 7 is disassembled, it is slid along the inner wall of the square groove 12, so that the outer wall of the mounting block 7 will separate from the inner wall of the square groove 12, thereby achieving disassembly. At the same time, by performing the opposite operation, the mounting block 7 can be installed to fit the square groove 12, thus making it more convenient to maintain the body 3.

[0034] In a preferred embodiment: one end of the outer wall of the double-ended lead screw 102 is provided with a forward thread and the other end is provided with a reverse thread. The slide rod 106 and slide rod 107 have the same shape and are respectively provided on both sides of the outer wall of the double-ended lead screw 102. The outer wall of slide rod 106 and slide rod 107 and the inner wall of straight groove 9 have the same shape and are slidably fitted to the inner wall of straight groove 9.

[0035] In the above structure, by setting up the double-ended lead screw 102, slide bar 106, and slide bar 2 107, the double-ended lead screw 102 rotates under the drive of the output shaft of the motor 101 when the motor 101 is started. The positive and negative threads formed at both ends of the double-ended lead screw 102 drive slide bar 106 and slide bar 2 107 to slide relative to each other along the inner wall of the straight groove 2 9. When slide bar 106 and slide bar 2 107 slide, they push one end of connecting rod 103 and connecting rod 2 105. The other end of connecting rod 103 and connecting rod 2 105 pushes the turntable 104 to rotate. The force points of the turntable 104 and connecting rod 103 and connecting rod 2 105 are at a 45-degree angle, which makes the slide bar 106 and slide bar 2 107 more stable when sliding relative to each other.

[0036] In a preferred embodiment: one end of the air tube 111 is connected to the air outlet of the corrugated hose 109, and the end of the air tube 111 away from the clamp 112 is connected to the air inlet of the airbag 113.

[0037] In the above structure, by setting the air tube 111 and the airbag 113, when the one-way valve 110 slides on the slide rod 106 and the connecting rod 103, one end of the one-way valve 110 will be compressed under force, and the gas in the inner cavity of the one-way valve 110 will be compressed to the other end. The gas at the other end of the one-way valve 110 will be transmitted to the air tube 111 through the air outlet. The air tube 111 will then transmit the gas to the inner cavity of the airbag 113. When the airbag 113 is in contact with the plate, the surface of the airbag will be filled with gas and extend to wrap and fix the surface of the plate, thereby avoiding the phenomenon of surface scratches when fixing the plate.

[0038] In a preferred embodiment: the corrugated hose 109, one-way valve 110, air tube 111, clamp 112 and airbag 113 are regarded as a movable component, and the movable component is symmetrically arranged about the rotation axis 108.

[0039] In the above structure, by setting up the corrugated hose 109, one-way valve 110, air pipe 111, clamp 112 and airbag 113, the two sets of corrugated hose 109, one-way valve 110, air pipe 111, clamp 112 and airbag 113 symmetrically arranged around the rotation axis 108 can pass through the transmission under the sliding of slide bar 106 and slide bar 107, thereby making the plate more stable when fixed.

[0040] Working principle: When the device is in use, the motor 101 is started, which causes the double-ended lead screw 102 to rotate under the drive of the output shaft of the motor 101. The positive and negative threads formed at both ends of the double-ended lead screw 102 drive the slide rod 106 and slide rod 107 to slide relative to each other along the inner wall of the straight groove 9. This causes the connecting rod 103 and connecting rod 105 to push the turntable 104 to rotate at a 45-degree angle. When the slide rod 106 and connecting rod 103 slide, they drive the one-way valve 110 to compress. The one-way valve 110 then transmits the gas in the inner cavity from the air outlet to the air pipe 111. The air pipe 111 then transmits the gas to the inner cavity of the airbag 113. When the clamp 112 contacts the plate, the airbag 113 expands to form a flexible contact layer surrounding the plate, thereby achieving precise positioning and non-destructive clamping of the plate.

[0041] Simultaneously, when disassembling and repairing the body 3 and clamping assembly 10, by pulling the lever 136, the lever 136 slides along the inner wall of the slide groove 14, causing one end of the wire rope 134 to extend outward, and the other end of the wire rope 134 pulls the spring 133 to slide along the inner wall of the sleeve 131. When the pin 132 slides, the spring 133 is compressed under the pressure of the pin 132, causing the outer wall of the pin 132 to disengage from the inner wall of the slot 8. Then, by sliding the mounting block 7 along the inner wall of the square groove 12, the outer wall of the mounting block 7 disengages from the inner wall of the square groove 12, thereby achieving convenient disassembly of the body 3 and clamping assembly 10 during maintenance. At the same time, convenient installation can be achieved through the same operation.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
