Description

Technical Field

[0001] The present invention relates to a steel plate stamping forming device, and more particularly to a stamping continuous progressive die device. Background Art

[0002] Continuous progressive die is a kind of equipment production and processing method, which is usually composed of several processing stations. Each station is responsible for the first-level stamping production of the raw material. The different stations are linked in sequence to form a coherent processing method, so that multiple steps of processing for multiple workpieces can be completed in one formation of the punch press. At the same time, after a stamping stroke is completed, the material is driven forward according to a fixed step distance through the feeding mechanism in the equipment. In this way, multiple processing steps can be completed on one mold, so that the overall space occupied by the device is small, the processing steps are compactly connected, and the overall processing efficiency is high.

[0003] At present, in the process of production and processing of workpieces by continuous progressive die equipment on the market, the processing raw materials are usually rolled up for transportation for easy transportation. During the processing, they usually have an arc-shaped stamping surface, which makes it difficult to accurately position the raw materials during the processing. Therefore, the raw materials need to be straightened before processing. The overall processing efficiency is low, the processing continuity is low, and in the processing process, the straightened materials are usually loaded manually, which is prone to safety hazards during the processing. In addition, the steel plates are easily folded during the processing, affecting the stamping accuracy and resulting in a decrease in the overall qualified rate. After the processing is completed, the waste materials and finished products cannot be classified and need to be manually classified, resulting in low processing efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a stamping continuous progressive die equipment that can automatically perform material discharging processing, has high processing continuity, and can automatically classify finished products and processing waste.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a stamping continuous progressive die device, comprising a processing base, a stamping structure being provided on the processing base, a positioning structure being provided at one end of the processing base, a buffer frame being provided between the positioning structure and the processing base, a discharging structure being provided on the side of the positioning structure opposite to the direction in which the processing base is provided, a raw steel coil being provided in the discharging structure, the discharging structure comprising an installation bracket, a turntable provided on the installation bracket, and a limiting bracket provided on the turntable, an installation gap for installing the raw steel coil being formed between the limiting bracket and the mounting bracket, the positioning structure comprising a positioning box body, a positioning rod provided in the positioning box body, and a guide table provided on the side of the positioning box body close to the processing base.

[0006] The present invention is further configured as follows: a positioning assembly is also provided in the positioning box body of the positioning structure, the positioning assembly includes a transmission roller arranged in the positioning box body, a punching part arranged on the top surface of the positioning box body, and a driving cylinder is provided on the punching part, and the driving cylinder is used to control the movement of the punching part in the vertical direction.

[0007] The present invention is further configured as follows: the stamping structure includes a positioning bracket arranged on the processing base, a stamping cylinder arranged on the positioning bracket, and a forming part arranged on the stamping cylinder. Buffer rods are also provided at both ends of the processing base, and buffer springs are provided on the buffer rods.

[0008] The present invention is further configured as follows: a flattening mechanism is provided between the positioning structure and the discharging structure, the flattening mechanism includes an upper flattening roller and a lower flattening roller, a material passing gap is provided between the upper flattening roller and the lower flattening roller, and adjustment devices are provided at both ends of the upper flattening roller and the lower flattening roller, and the adjustment device is used to change the relative distance between the upper flattening roller and the lower flattening roller.

[0009] Preferably, a tensioning assembly is further provided on the processing base, and the tensioning assembly includes a plurality of support rods arranged on both sides of the processing base, each of the support rods is provided with a positioning groove, the position of the positioning grooves on each of the support rods is the same, and the distance between the support rods on both sides of the processing base is the same as the width of the raw steel coil.

[0010] The present invention is further configured as follows: a discharge assembly is also provided on the processing base, the discharge assembly includes a discharge hole provided on the processing base and a material channel provided in the discharge hole, a material frame is also provided at the bottom of the material channel, and a cutting assembly is also provided at the other end of the processing base away from the positioning structure, the cutting assembly includes a cutting knife provided on the stamping mechanism and a cutting baffle provided on the processing base, and the cutting knife and the cutting baffle are located on the same vertical plane.

[0011] Preferably, the processing base is provided with a plurality of processing tables in sequence along its length direction, and the position and shape of each processing table matches the molded part.

[0012] Preferably, one end of the processing base provided with the cutting assembly is also provided with a waste channel, and the waste channel is configured as an inclined steel plate, and the waste channel is used to collect waste materials after cutting.

[0013] By adopting the above technical solution, the beneficial effects are as follows: 1. The present application forms a fully automatic processing flow from raw material transportation, stamping and forming to finished product-waste automatic classification in the equipment through the coordinated cooperation of the integrated stamping structure, positioning structure, discharging structure and cutting assembly. The positioning structure is linked by the transmission roller, the adjustment rod and the punching part, and the raw steel coil is calibrated by the flattening mechanism and the tensioning assembly before processing, so that it remains parallel to the processing base during the processing. The tensioning assembly ensures that the raw steel coil is always in a taut state through the fragrance design of the support rod and the positioning groove, avoiding the raw steel coil from being in a taut state during the processing. The offset and wrinkles ensure that the stamping position of the stamping structure is accurately controllable when the material is continuously fed. The stamping structure adopts a matching setting of a multi-station processing table and a formed part, and is combined with a buffer rod and a buffer spring arranged on the buffer rod to absorb the impact force of the stamping structure, thereby improving the stamping continuity and processing stability during the processing. The combination of the waste channel and the cutting component realizes the separation and collection of finished products and waste. The above solution solves the shortcomings of frequent interruptions, frequent manual intervention, and mixed waste in the processing process of traditional processing equipment. The overall processing efficiency and processing precision are high, and the processing loss is small.

[0014] 2. Furthermore, the present application effectively improves the shape stability of the raw material before processing through the dual control structure of the positioning structure and the flattening structure. The transmission roller and the adjustment rod arranged in the positioning box can dynamically adjust the travel path of the raw material. The punching part can complete the pre-punching positioning under the control of the driving cylinder. The spacing between the punching holes used for positioning is the same, and the spacing between the punching holes can be adjusted according to the size of the workpiece, so that accurate positioning can be achieved in the subsequent stamping process of the raw material by the stamping structure to prevent waste of raw materials. The stamping structure realizes the stamping and forming processing of the raw material through the forming part and the processing table, and the shape of the finished product can be adjusted by changing the shape of the forming part and the processing table. At the same time, the flattening mechanism adopts the flattening rollers of the upper and lower equipment. The wheel design is used, and the gap between the upper flattening roller and the lower flattening roller is adjusted through the adjustment device, so that the raw steel coil is flattened. Specifically, the steel coil needs to be compressed to form a spiral shape during processing, so it will have a tendency to bend upward or downward when the steel plate is pulled out, which will cause deviation during the stamping positioning and processing of the steel plate, thereby affecting the accuracy of the stamping process and reducing the qualified rate of the product. The flattening mechanism is used to perform multi-stage straightening and stress relief treatment on the drawn raw steel coil, so that the shape of the steel plate can tend to be a straight line, which can eliminate the influence of coil bending or local deformation on stamping. The above setting can not only reduce the processing error caused by raw material deformation, but also adapt to the flattening setting of materials of different thickness and hardness, greatly expanding the range of equipment raw materials.

[0015] 3. At the same time, during the processing, the tensioning assembly can buffer and balance the raw steel plate by setting the support rods on both sides of the processing base, so as to maintain the constant tension during the stamping process, and the distance between the support rods at both ends of the processing base can be adjusted according to the width of the steel plate. During the processing, the position of the raw steel plate is limited by the support rods, which avoids the displacement caused by instantaneous inertia during the stamping process. In addition, the buffer rods cooperate with the springs to form a shock-absorbing structure to absorb the impact force during the stamping process, thereby reducing the interference of the vibration of the equipment on the stamping accuracy during the stamping process. At the same time, after the stamping process of the workpiece is completed, the discharge assembly is set A discharge hole is provided on the processing base and on the moving path of the material. The material is cut, shaped and cut off by the stamping structure, and the material is separated from the raw steel plate. At the same time, since the height between the raw steel plate and the processing base is less than the height of the finished product, the finished product can conflict with the raw steel plate, so that the processed product is pushed by the raw steel plate to move along the length direction of the processing base. When the processed product moves to the position of the discharge hole, under the influence of gravity, the finished product enters the material channel of the discharge hole and enters the material frame. The processed waste continues to move to the cutting component, is cut off by the cutting component and enters the waste channel, and the four-line finished product and waste are automatically classified.

[0016] 4. In addition, the equipment combination of the present application is designed to be fully automatic, so that the overall processing process avoids human intervention. The discharging structure realizes the automatic discharging of steel coils through the cooperation of the turntable and the limit frame, reducing the downtime for changing materials. The waste channel adopts an inclined steel plate to guide the waste materials after cutting to be collected in a centralized manner, so as to prevent the waste materials after cutting from accumulating at the end of the stamping structure and causing processing jams. During the processing, a multi-station setting is adopted to optimize the overall processing path. The forming parts and processing tables used for stamping and forming raw materials can be switched as needed, so that operations such as punching, cutting and stamping of workpieces can be conveniently realized to meet the diverse product processing needs.
