A terminal crimping machine and cutting structure

Abstract

This utility model provides a terminal crimping machine and a cutting structure, including: a feeding machine, a pressing component, a lowering component, and a side adjusting electric cylinder. The feeding machine is a spiral feeding mechanism. Compared with the prior art, this utility model has the following advantages: In actual use, when the pressing process is started, the side pushing electric cylinder drives the side pushing rod to move laterally through rack and pinion transmission. The meshing rotary gear synchronously drives the connecting sleeve to rotate, so that the pressure head at the end of the telescopic rod is accurately positioned above the stepping groove. The cutting electric cylinder completes the lateral cutting action under the guidance of the outer support frame. At the same time, the lowering component works in conjunction, and the top pressing electric cylinder pushes the rocker arm through the movable connector, so that the top cutting blade on the movable seat is pushed up from below the conveying component, forming a bidirectional shearing with the cutting electric cylinder. The positioning support column keeps the conveyor belt stable during the cutting process. The cut finished product slides down the discharge ramp, thereby effectively improving the cutting efficiency of terminal materials.

Description

Technical Field

[0001] This utility model belongs to the field of terminal cutting technology, and relates to a terminal cutting machine and a cutting structure. Background Technology

[0002] The low cutting efficiency in existing terminal production processes is mainly due to the following drawbacks: Traditional cutting equipment relies on manual adjustment of feeding parameters, which can easily lead to dimensional deviations and defective products when there are slight fluctuations in the thickness and hardness of the terminal material; in multi-variety, small-batch production, mold replacement and debugging can take 30-60 minutes, resulting in equipment idle rates exceeding 25%; and the lack of a real-time monitoring mechanism for cutting tool wear, which usually relies on operator experience to determine when to replace them, leading to excessive burrs on the cut surfaces and increased tool costs due to premature replacement. These drawbacks are caused by the fact that terminal materials are mostly copper alloys or nickel-plated steel strips, whose mechanical properties vary from batch to batch due to the rolling process, while existing equipment lacks sufficient adaptive adjustment capabilities. Conventional solutions include: assigning dedicated personnel to randomly check cutting dimensions every hour and manually correct feeding compensation values; adopting a quick mold change system (SMED) to standardize mold change procedures; and establishing a tool replacement log to force tool replacement according to the processing quantity. However, these methods have obvious drawbacks: manual sampling is lagging, and sampling 10 samples per hour can only cover 0.3% of the production volume, which can easily lead to the outflow of batches of defective products. Therefore, there is an urgent need for a terminal block machine and cutting structure to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a terminal cutting machine and a cutting structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a terminal crimping machine and a cutting structure, including: a feeding machine, a pressing component, a bottom lifting component, and a side adjusting electric cylinder. The feeding machine is a spiral feeding mechanism. The left side of the feeding machine is provided with a set of guide heads for sequentially guiding terminal materials. The left side of the guide heads is provided with a set of feeding grooves for arranging and guiding several sets of terminal materials. The cross-section of the feeding groove is a concave structure. The interior of the guide heads is consistent with the cross-sectional shape of the feeding groove, and the interiors are correspondingly connected to each other.

[0005] On the left side of the feed trough, there is a set of pushers for transferring the terminal material inside the feed trough at a right angle. Inside the pushers, there are stepping grooves for progressively pushing the terminal material. The cross-sectional shape of the stepping grooves is the same as the internal structure of the feed trough. The stepping grooves are arranged at a right angle to the feed trough. At the rear of the stepping groove, there is a set of push rods for actively pushing the terminal material. The initial retraction of the push rods forms the rear side of the right-angle connection between the feed trough and the stepping groove. At the upper middle position of the stepping groove, there is a set of pressing components for pressing multiple terminal materials together. First, the spiral mechanism is activated... The feeder pushes terminal materials into the guide head via rotation. The guide head adjusts the disordered materials into a single row of directional conveyors, achieving precise arrangement through the concave cross-section feed trough. When the material reaches the end of the feed trough, the stepping groove in the pusher seat forms a right-angle transition structure with the feed trough. At this time, the rear push rod extends from the initial retracted position, pushing the material laterally into the stepping groove to complete a 90-degree turn. The pressing component then applies vertical pressure to multiple sets of terminals in the middle section of the stepping groove. The pressing body simultaneously completes positioning and fixing. The cutting electric cylinder drives the cutter to perform precise cutting. The lower push component assists in pushing out the finished product. Finally, the cut terminals slide into the collection area along the discharge ramp.

[0006] In a preferred embodiment, the pressing component includes a side-push electric cylinder and a pressing head. The left side of the side-push electric cylinder is provided with a rack for moving the side push rod left and right, and the middle position of the rack is provided with a set of rotary gears for driving the connecting sleeve, telescopic rod and pressing head to rotate and adjust.

[0007] In a preferred embodiment, the rotary gear meshes with the rack, the inner side of the rotary gear is fixedly connected to the outer side of the middle position of the connecting sleeve, and the inner side of the connecting sleeve is provided with a set of telescopic rods for controlling the up and down extension of the pressure head.

[0008] In a preferred embodiment, the lower end of the telescopic rod is provided with a set of pressure heads for pressing the terminal material. The pressure heads are located at the upper end of the middle position of the stepping groove, and the outer side of the upper end of the connecting sleeve is provided with a set of limiting blocks for keeping it in place.

[0009] In a preferred embodiment, the outer side of the limiting block is provided with a set of side adjusting electric cylinders for driving the pressing components to move left and right, and the front side of the stepping groove is provided with a set of conveying components for guiding several sets of pressing bodies. The conveying components are hollow structures.

[0010] In a preferred embodiment, the upper end of the conveying component is provided with several sets of pressing bodies, the front side of the conveying component is provided with a set of discharge ramps for unloading the pressing bodies, the upper outer side of the middle position of the conveying component is provided with a set of outer support frames for supporting the cutting electric cylinders, and the middle position of the outer support frames is provided with a set of cutting electric cylinders for cutting the pressing bodies.

[0011] In a preferred embodiment, the lower end of the middle position of the conveying component is provided with a set of lower lifting components for supporting and lifting the bottom of the pressing body. The lower lifting components include a pressing electric cylinder and a positioning support column. The lower end of the pressing electric cylinder is provided with a set of movable connectors for driving the rocker arm to move.

[0012] In a preferred embodiment, the inner side of the movable connector is provided with a set of rocker arms for lifting several sets of top cutting blades. The lower left end of the rocker arms is provided with a support frame for limiting its movement. The upper left end of the rocker arms is provided with a set of movable seats for driving several sets of top cutting blades to lift the lower end of the pressing body. The front and rear sides of the top cutting blades are each provided with a set of positioning support columns for flexibly supporting the lower end of the conveying component. In actual use, when the pressing process starts, the side-push electric cylinder drives the side-push rod to move laterally via rack and pinion transmission. The meshing rotary gear synchronously drives the connecting sleeve to rotate, so that the pressure head at the end of the telescopic rod is accurately positioned at the step. Above the inlet slot, when the telescopic rod presses down, the pressure head vertically presses the arranged terminal materials. The limit block ensures that the connecting sleeve is stable and does not shift. After the side adjustment electric cylinder finely adjusts the overall position of the pressing component, the hollow structure of the conveying component transports the pressing body to the cutting station. The cutting electric cylinder completes the transverse cutting action under the guidance of the outer support frame. At the same time, the lower push component works in conjunction. The top pressure electric cylinder pushes the rocker arm through the movable connector, so that the top cutting blade on the movable seat pushes up from below the conveying component, forming a bidirectional shearing with the cutting electric cylinder. The positioning support column keeps the conveyor belt stable during the cutting process. The cut finished product slides down the discharge ramp, thereby effectively improving the cutting efficiency of terminal materials.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: First, the spiral feeder is started, and the terminal material is pushed into the guide head by rotation. The guide head adjusts the disordered material into a single row of directional conveying. The material is precisely arranged through the concave cross section of the feed trough. When the material reaches the end of the feed trough, the stepping groove in the pusher seat forms a right angle transition structure with the feed trough. At this time, the rear push rod extends from the initial contraction position and pushes the material laterally into the stepping groove to complete a 90-degree turn. The pressing component then applies vertical pressure to multiple sets of terminals in the middle section of the stepping groove. The pressing body simultaneously completes the positioning and fixing. The cutting electric cylinder drives the cutter to perform precise cutting. The lower top component cooperates to push out the finished product. Finally, the cut terminal slides into the collection area along the discharge ramp.

[0014] In practical use, when the crimping process starts, the side-push electric cylinder drives the side push rod to move laterally through rack and pinion transmission. The meshing rotary gear synchronously drives the connecting sleeve to rotate, so that the pressure head at the end of the telescopic rod is accurately positioned above the stepping groove. When the telescopic rod presses down, the pressure head performs vertical crimping on the arranged terminal materials. The limit block ensures that the connecting sleeve is stable and does not deviate. After the side adjustment electric cylinder finely adjusts the overall position of the crimping component, the hollow structure of the conveying component transports the crimping body to the cutting station. The cutting electric cylinder completes the lateral cutting action under the guidance of the outer support frame. At the same time, the lower push component works in conjunction. The top pressing electric cylinder pushes the rocker arm through the movable connector, so that the top cutting blade on the movable seat pushes up from below the conveying component, forming a bidirectional shearing with the cutting electric cylinder. The positioning support column keeps the conveyor belt stable during the cutting process. The cut finished product slides down the discharge ramp, thereby effectively improving the cutting efficiency of terminal materials. Attached Figure Description

[0027] The rotary gear 14f meshes with the rack 14c. The inner side of the rotary gear 14f is connected and fixed to the outer side of the middle position of the connecting sleeve 14g.
