Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, and more particularly to a modular automatic feeding and automatic receiving stamping die. Background Art

[0002] In modern manufacturing, stamping technology, as an important part of metal processing, is widely used in many fields such as automobiles, home appliances, and electronics. With the accelerated development of production automation and intelligentization, the performance requirements for stamping dies are also increasing, especially in terms of production efficiency, precision control, and automation level. However, the stamping dies widely used in the current market often have problems in terms of continuous operation and precise positioning, which directly affects the overall efficiency of the production line and product quality.

[0003] Although many traditional stamping dies can achieve a certain degree of automated production, they have obvious shortcomings in continuous operation. These dies usually need to reload materials manually or semi-automatically after each stamping, which leads to production interruptions and reduces overall production efficiency. Even if some molds are equipped with automatic feeding mechanisms, they often affect the stability and efficiency of continuous operation due to problems such as mismatch between feeding speed and stamping rhythm and inaccurate material positioning. Accurate positioning is the key to ensuring the quality of stamped parts. Although some high-end stamping dies can achieve high-precision positioning in a single stamping, they cannot achieve continuous operation, and the stamping efficiency is low. In addition, due to the influence of various factors such as material deformation, mechanical wear, and vibration interference, the positioning accuracy is difficult to maintain for a long time. The method of relying on manual adjustment of positioning is not only inefficient, but also increases the risk of human error, and it is difficult to adapt to large-scale, high-precision production needs.

[0004] In view of the above technical bottlenecks, it is particularly important to develop a modular automatic feeding and automatic receiving stamping die that has both continuous operation capability and accurate positioning.

[0016] Preferably, the present invention also provides a method of use, comprising the following steps:

[0017] S1, intermittent feeding operation;

[0018] When the workpiece needs to be unloaded, the cylinder is driven to return to drive the connecting piece to reciprocate, and the connecting piece drives one of the hinge plates to move. Since both ends of the hinge plate are rotatably connected to the rotating bottom block, the rotating bottom block drives one of the rotating shafts to rotate on the bearing plate, and the rotating bottom block drives the first stopper to rotate, so that the workpiece stacked on the bottom layer falls through the unloading hole, and the second stopper rotates synchronously, so that the second to last workpiece on the bottom layer is supported on the second stopper, and so on, reciprocating to form intermittent unloading;

[0019] S2, fixture adjustment operation;

[0020] Adjust the clamping mode according to the shape of the stamping workpiece;

[0021] S2.1. When it is necessary to clamp a rectangular workpiece, firstly, one of the sprockets is driven to rotate by an external driving mechanism, and the sprocket drives the chain to rotate, and the chain rotation synchronously drives several sprockets to rotate synchronously. When the sprocket rotates, the gear fixedly connected to it rotates synchronously on the fixed plate, and the gear meshes with the tooth grooves provided on the opposing movable plates on both sides, thereby driving the two opposing movable plates to move in opposite directions. When the opposing movable plates move, the straight slot holes and the oblique slot holes are synchronously driven to move, and the two opposing movable plates move outward synchronously, so that the straight slot holes and the oblique slot holes are synchronously driven to move outward. The straight slot holes make several sliding hinge shafts that are slidably inserted form a straight line. Since several contact blocks are hingedly connected by the sliding hinge shaft, several contact blocks form a straight line, which is used for positioning and clamping rectangular workpieces.

[0022] S2.2. When it is necessary to clamp a circular workpiece, one of the sprockets is driven to rotate through an external driving mechanism, and the sprocket drives the chain to rotate, and the chain rotation synchronously drives several sprockets to rotate synchronously. When the sprocket rotates, the gear fixedly connected to it rotates synchronously on the fixed plate, and the gear meshes with the tooth grooves provided on the opposing movable plates on both sides, thereby driving the two opposing movable plates to move in opposite directions. When the opposing movable plates move, the straight slot holes and the oblique slot holes are synchronously driven to move. The two opposing movable plates move inward synchronously, so that the straight slot holes and the oblique slot holes are synchronously driven to move inward. The movement of the oblique slot holes squeezes several sliding hinge shafts that are slidably inserted to form a semicircular arc shape. Since several contact blocks are hingedly connected through the sliding hinge shaft, several contact blocks form a semicircular arc shape, which is used to position and clamp the circular workpiece;

[0023] S3, continuous conveying operation;

[0024] The drive reduction motor drives the reciprocating shaft of the reciprocating assembly to rotate, and the annular curved groove opened on the outer wall of the reciprocating shaft rotates synchronously. The rotation of the annular curved groove causes the sliding rod with one end slidingly inserted in the annular curved groove to slide back and forth on the fixed sleeve, and the linkage plate is pushed by the sliding rod. The linkage plate drives the sliding conveying assembly to reciprocate, and the linkage plate drives the symmetrical first sliding block to slide on the first sliding rail, and the first sliding block drives the second sliding rail and the second sliding block at its top to slide synchronously. Since the clamping rod is slidably embedded in the sliding groove of the trapezoidal block through the third sliding block, and the sliding groove of the trapezoidal block is inclined, the two third sliding blocks slide inwardly, driving the clamping rod and the second sliding block to move on the second sliding rail, and the clamping rod drives a number of adjustable clamping groups to squeeze inwardly to form a clamping action while reciprocating, thereby realizing the effect of continuously and sequentially conveying the workpieces;

[0025] S4, stamping and joining operation;

[0026] When the continuous feeding mechanism conveys the workpiece to the bottom of the punching mechanism, the punching mechanism punches it. After punching, the continuous feeding mechanism conveys the workpiece to the receiving box to complete the punching.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention improves the existing stamping die by arranging a stamping mechanism, an intermittent feeding mechanism, a reciprocating drive mechanism and a continuous feeding mechanism on a stamping base, and arranging a material receiving box at the end of the stamping base. The reciprocating drive mechanism drives the adjustable clamp group to realize continuous and precise feeding through a sliding conveying component and a sliding clamping component. The adjustable clamp group is further designed so that the adjustable clamp group has the function of precisely clamping circular workpieces and rectangular workpieces. The present invention can realize fast, accurate and continuous conveying and receiving of materials while ensuring stamping accuracy, thereby greatly improving production efficiency, reducing labor costs, and improving product quality stability.

[0029] 2. In the present invention, a mounting frame is provided at a position on the back of the stamping base away from one end of the stamping mechanism, a carrying plate is fixedly connected to the top of the mounting frame, a feeding hole is provided on the carrying plate, four vertical plates for stacking materials are arranged at equal intervals in a ring around the feeding hole, when the workpiece needs to be unloaded, the cylinder is driven to return to drive the connecting member to reciprocate, and the connecting member drives one of the hinge plates to move, because both ends of the hinge plate are rotatably connected to the rotating bottom block, so that the rotating bottom block drives one of the rotating shafts to rotate on the carrying plate, and the rotating bottom block drives the first stop block to rotate, so that the workpiece stacked on the bottom layer falls through the feeding hole, and the second stop block rotates synchronously, so that the second to last workpiece on the bottom layer is supported on the second stop block, and so on, reciprocating to form intermittent unloading, which can accurately control the production rhythm, improve production accuracy and flexibility, reduce waste and cost, and enhance production safety and quality control capabilities.

[0030] 3. In the present invention, one of the sprockets is driven to rotate by an external driving mechanism, and the sprocket drives the chain to rotate, and the chain rotation synchronously drives several sprockets to rotate synchronously. When the sprocket rotates, the gear fixedly connected to it rotates synchronously on the fixed plate, and the gear meshes with the tooth grooves provided on the opposite moving plates on both sides, thereby driving the two opposite moving plates to move in opposite directions. When the opposite moving plates move, the straight slot holes and the oblique slot holes are synchronously driven to move. When it is necessary to clamp a rectangular workpiece, the two opposite moving plates move outward synchronously, so that the straight slot holes and the oblique slot holes are synchronously driven to move outward. The straight slot holes make several sliding hinge shafts formed in a straight line. Due to several The contact blocks are hingedly connected by sliding hinges, so that several contact blocks form a straight line for positioning and clamping rectangular workpieces; when a circular workpiece needs to be clamped, the two opposing movable plates move inward synchronously, so that the straight slot holes and the oblique slot holes are synchronously driven to move inward, and the movement of the oblique slot holes squeezes several sliding hinges to form a semicircular arc. Since several contact blocks are hingedly connected by sliding hinges, several contact blocks form a semicircular arc for positioning and clamping circular workpieces; it helps to reduce the complexity and manufacturing cost of the mold, so that the production of stamping parts with different specifications and different requirements can be flexibly configured, thereby improving the versatility and adaptability of the equipment.

[0072] When a rectangular workpiece needs to be clamped, the two opposing movable plates 5033 move outward synchronously, thereby synchronously driving the straight slot 5036 and the oblique slot 5037 to move outward. The straight slot 5036 enables a plurality of sliding hinge shafts 5039 to form a straight line. Since a plurality of contact blocks 5038 are hingedly connected via the sliding hinge shafts 5039, the plurality of contact blocks 5038 form a straight line, which is used for positioning and clamping the rectangular workpiece.

[0073] When it is necessary to clamp a circular workpiece, the two opposing movable plates 5033 move inward synchronously, thereby synchronously driving the straight slot 5036 and the oblique slot 5037 to move inward. The oblique slot 5037 moves to squeeze a number of sliding hinge shafts 5039 that are slidably inserted to form a semicircular arc shape. Since a number of contact blocks 5038 are hingedly connected through the sliding hinge shaft 5039, the several contact blocks 5038 form a semicircular arc shape for positioning and clamping the circular workpiece; this helps to reduce the complexity and manufacturing cost of the mold, so that the production of stamping parts with different specifications and different requirements can be flexibly configured, thereby improving the versatility and adaptability of the equipment.

[0077] When the workpiece needs to be unloaded, the driving cylinder 303 drives the connecting member 3056 to reciprocate, and the connecting member 3056 drives one of the hinge plates 3055 to move. Since both ends of the hinge plate 3055 are rotatably connected to the rotating bottom block 3052, the rotating bottom block 3052 drives one of the rotating shafts 3051 to rotate on the carrying plate 302, and the rotating bottom block 3052 drives the first stopper 3053 to rotate, so that the workpiece stacked on the bottom layer falls through the unloading hole 304, and the second stopper 3054 rotates synchronously, so that the second to last workpiece of the bottom layer is supported on the second stopper 3054, and so on, reciprocating to form intermittent unloading;

[0078] S2, fixture adjustment operation;

[0079] Adjust the clamping mode according to the shape of the stamping workpiece;

[0080] S2.1. When a rectangular workpiece needs to be clamped, firstly, one of the sprockets 5041 is driven to rotate by an external driving mechanism, and the sprocket 5041 drives the chain 5042 to rotate, and the chain 5042 rotates synchronously to drive several sprockets 5041 to rotate synchronously. When the sprocket 5041 rotates, the gear 5035 fixedly connected thereto rotates synchronously on the fixed plate 5031, and the gear 5035 meshes with the tooth grooves 5034 provided on the opposite moving plates 5033 on both sides, thereby driving the two opposite moving plates 5033 to move in opposite directions. When the opposing moving plates 5033 move, the linear slots 5036 and the oblique slots 5037 are synchronously driven to move. The two opposing moving plates 5033 move outward synchronously, so as to synchronously drive the linear slots 5036 and the oblique slots 5037 to move outward. The linear slots 5036 enable a plurality of sliding hinge shafts 5039 that are slidably inserted to form a straight line. Since a plurality of contact blocks 5038 are hingedly connected via the sliding hinge shafts 5039, the plurality of contact blocks 5038 form a straight line, which is used for positioning and clamping a rectangular workpiece.

[0081] S2.2, when it is necessary to clamp a circular workpiece, one of the sprockets 5041 is driven to rotate by an external driving mechanism, the sprocket 5041 drives the chain 5042 to rotate, the chain 5042 rotates synchronously to drive several sprockets 5041 to rotate synchronously, when the sprocket 5041 rotates, the gear 5035 fixedly connected thereto rotates synchronously on the fixed plate 5031, the gear 5035 meshes with the tooth grooves 5034 provided on the opposite moving plates 5033 on both sides, thereby driving the two opposite moving plates 5033 to move in opposite directions, when When the opposite moving plates 5033 move, the straight slots 5036 and the oblique slots 5037 are synchronously driven to move. The two opposite moving plates 5033 move inward synchronously, so as to synchronously drive the straight slots 5036 and the oblique slots 5037 to move inward. The movement of the oblique slots 5037 squeezes a plurality of sliding hinge shafts 5039 that are slidably inserted to form a semicircular arc shape. Since a plurality of contact blocks 5038 are hingedly connected through the sliding hinge shafts 5039, the plurality of contact blocks 5038 form a semicircular arc shape, which is used for positioning and clamping a circular workpiece.

[0082] S3, continuous conveying operation;

[0083] The driving reduction motor 401 drives the reciprocating shaft 4021 of the reciprocating assembly 402 to rotate, and the annular curved groove 4022 opened on the outer wall of the reciprocating shaft 4021 rotates synchronously. The rotation of the annular curved groove 4022 causes the sliding rod 4024, one end of which is slidably inserted inside the annular curved groove 4022, to slide back and forth on the fixed sleeve 4023. The sliding rod 4024 pushes the linkage plate 403, and the linkage plate 403 drives the sliding conveying assembly 501 to reciprocate. The linkage plate 403 drives the symmetrical first sliding block 5012 to slide on the first sliding rail 5011, and the first sliding block 5012 drives The second slide rail 5021 and the second slider 5022 at the top thereof slide synchronously. Since the clamping rod 5023 is slidably embedded in the slide groove 5026 of the trapezoidal block 5025 through the third slider 5024, and since the slide groove 5026 of the trapezoidal block 5025 is inclined, the two third sliders 5024 slide inwardly, driving the clamping rod 5023 and the second slider 5022 to move on the second slide rail 5021. The clamping rod 5023 drives the plurality of adjustable clamping groups 503 to reciprocate while squeezing inwardly to form a clamping action, thereby achieving the effect of continuously and sequentially conveying the workpieces.
