Description

Technical Field

[0001] This utility model belongs to the field of power distribution equipment processing technology, and specifically relates to a busbar trunking cutting and shearing device. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Busbar trunking is required from a 630KVA transformer to a distribution cabinet. However, traditional cutting and shearing devices fix only one side of the busbar trunking. During cutting, the busbar trunking may twist or deform due to unilateral force, or the workpiece may shift, resulting in a slanted cut or a stepped cross-section. Furthermore, traditional cutting and shearing devices cause continuous friction between the busbar trunking at both ends and the cutting tool after cutting, resulting in a large amount of burrs on the edges of the busbar trunking, affecting its use and requiring further burr removal. To solve the problems mentioned above, we propose a busbar trunking cutting and shearing device. Utility Model Content

[0003] The purpose of this utility model is to provide a busbar trunking cutting and shearing device, which has the advantages of concentric clamping at both ends and reducing secondary damage during cutting.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a busbar trunking cutting and shearing device, comprising a trunking plate B, side plates B slidably connected to both sides of the inner wall of the trunking plate B, connecting rods B bolted to opposite sides of the two side plates B, sliding sleeves bolted to the top and bottom of the connecting rods B, a sliding rod slidably sleeved inside the sliding sleeves, a connecting rod A bolted to the front and rear ends of the opposite side of the sliding rod on one side away from the middle, a clamping plate bolted to the back of the connecting rod A and the front of the connecting rod B, a bracket fixedly sleeved to the front end of the sliding rod near the middle, a protective mechanism provided at the bottom of the bracket, and a driving mechanism provided on the back of the trunking plate B.

[0005] The above technical solution is adopted as follows: Cylinder A drives the channel plate B to move forward, channel plate B drives the side plate B to move, side plate B drives the connecting rod B to move, connecting rod B drives the sliding sleeve to move, the sliding rod limits the movement of the sliding sleeve, and the movement of the connecting rod B drives the clamping plate located at the rear end to move forward, concentrically clamping both ends of the busbar. Concentric clamping can evenly distribute the cutting stress, avoid the twisting or local deformation of the busbar caused by unilateral force, maintain the geometric accuracy of the conductor arrangement, effectively offset the vibration generated by the contact between the tool and the material during the cutting process, reduce the risk of chipping of the cut edge, and ensure that the cutting trajectory is completely coincident with the axis of the busbar, avoiding the inclination of the cut or the stepped cross-section caused by the workpiece offset.

[0006] The present invention is further configured such that the protective mechanism includes a slider, the slider is bolted to the bottom of the bottom bracket, a rocker arm is hinged to the bottom of the slider, a turntable is hinged to the bottom of one end of the two rocker arms, and a motor is fixedly sleeved to the bottom of the turntable.

[0007] The above technical solution employs a protective mechanism. The motor's movement drives the turntable to rotate, which in turn moves the rocker arm. The rocker arm's movement moves the slider, which in turn moves the support to both sides. The support moves the sliding rod, which in turn moves connecting rod A and connecting rod B. Side plates A and B expand outwards due to the movement of connecting rods A and B, separating the feeder grooves at both ends after cutting. Timely separation prevents the cut parts from sliding or tipping due to gravity and mechanical stress, reducing secondary injuries such as pinching and collisions. The separation action reduces continuous friction between the cutting surface and the tool, preventing the expansion of burrs and extending tool life. When cutting metal materials, timely separation interrupts the continuous heat transfer between workpieces, reducing material thermal deformation. The separation action eliminates the tensile deformation caused by the weight of the materials at both ends, maintaining the flatness of the cut to meet requirements.

[0008] The present invention is further configured such that the driving mechanism includes a cylinder A, the cylinder A is bolted to the back of the slot plate B, the back of the cylinder A is bolted to the slot plate A, and the two sides of the inner wall of the slot plate A are slidably connected to side plates A, and the opposite sides of the two side plates are bolted to the opposite sides of the two connecting rods A located at the rear end.

[0009] The above technical solution is adopted: by setting up a driving mechanism, cylinder A drives the slot plate B to move forward, slot plate B drives the side plate B to move, side plate B drives the connecting rod B to move, and side plate A and side plate B can be extended outward due to the movement of connecting rod A and connecting rod B.

[0010] The present invention is further configured such that a sliding groove is slidably connected to the surface of the slider, and a base plate is provided outside the sliding groove.

[0011] The above technical solution uses a sliding groove to limit the movement of the slider.

[0012] The present invention is further configured such that a support plate is bolted to the middle of the front end of the top of the base plate, a horizontal plate is bolted to the top of the support plate, a cylinder B is bolted to the rear end of the bottom of the horizontal plate, a tool holder is bolted to the bottom of the cylinder B, tools are arranged on both sides inside the tool holder, and a drive box is arranged on the left side of the tool holder.

[0013] The above technical solution is adopted: by setting up a drive box, a tool holder and a tool, the drive box drives the tool to rotate and cut, the tool holder stabilizes the tool, and by setting up cylinder B, the tool can be driven to move up and down to cut.

[0014] The present invention is further configured such that support legs are bolted to the four corners of the bottom of the base plate, and a base is bolted to the bottom of the support legs, with the middle of the top of the base embedded in the bottom of the motor.

[0015] The above technical solution, by setting up support legs and a base, can stabilize the device and motor.

[0016] The present invention is further configured such that a spring is sleeved in the middle of the surface of the slide rod.

[0017] The above technical solution incorporates a spring to cushion the clamping of the clamping bracket.

[0018] The present invention is further provided that an anti-slip pad is adhered to one side of the two clamps facing each other.

[0019] The above technical solution reduces friction when the clamping plates are used by setting up anti-slip pads.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model can evenly distribute cutting stress through concentric clamping, avoid twisting or local deformation of the busbar groove due to unilateral force, maintain the geometric accuracy of conductor arrangement, effectively counteract the vibration generated by the contact between the tool and the material during the cutting process, reduce the risk of chipping of the cut edge, and ensure that the cutting trajectory is completely coincident with the axis of the busbar groove, avoiding the inclination of the cut or the stepped cross section caused by the workpiece offset.

[0022] 2. This utility model can avoid the sliding or tipping of the cut parts caused by gravity and mechanical stress by timely separation, reducing secondary damage such as pinching and collision. The separation action can reduce the continuous friction between the cutting surface and the tool, prevent the burrs of the cut from expanding and extend the service life of the tool. When cutting metal materials, timely separation can interrupt the continuous heat transfer between the workpieces, reduce the thermal deformation of the material, and eliminate the tensile deformation of the materials at both ends caused by their own weight, maintaining the flatness of the cut to meet the requirements.
