Description

Technical Field

[0001] The invention relates to an auxiliary processing technology for a vacuum tube tail frame, in particular to an automatic stamping device for a tail frame head and a processing technology for the application thereof. Background Art

[0002] With the continuous improvement of people's living standards and the continuous enhancement of environmental protection and energy-saving awareness. At present, solar water heater projects are increasingly used in public places such as hotels, restaurants, schools, residential buildings, office buildings, etc. In the known solar water heater heating device, the vacuum tube tail support device for the solar water heater is mainly composed of a tail support bracket and a plurality of tail supports, which are provided with a plurality of mounting holes on the tail support bracket, and the tail support is installed in the mounting holes. For example, application No. 201120216338.2 discloses a novel upright solar water heater bracket tail support, which is mainly composed of a tail support and a fixing plate, and the tail support is provided with a groove matching the vacuum tube, and the tail of the vacuum tube can be placed in the corresponding groove, so as to position the vacuum tube in the groove, so that the vacuum tube is not easily damaged during the installation and disassembly process, and the fixing plate is positioned on the tail support, and the fixing plate can close the groove opening and extend to the top of the vacuum nozzle of the vacuum tube exhaust end.

[0003] Both ends of the tail support tripod mentioned above need a head to seal, which is convenient for protecting the vacuum tube collector tube and facilitating operation to prevent other things from entering the tail support tripod. The head is an irregular pentahedron that matches the end of the commissioned tripod and has an opening on the top. The head is currently processed by using a cutting machine to cut it into squares of specified sizes, and then trimming the edges. After trimming, it enters a punching machine for stamping and curling. Such an operating process line is too cumbersome, and the cut squares enter the trimming machine and punching machine. Due to their small size and difficulty in operation, the safety of employees operating them is too poor and the efficiency is too low. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an automated stamping equipment and processing technology for the tail leg frame head which can realize automated continuous production, and can automatically produce the head from the unwinding of the stamped sheet on a line, without excessive manual intervention in production, reducing the degree of employee participation and improving production safety.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an automated stamping equipment for a tail leg head, comprising a unwinding wheel, a servo feeding device, a stamping base, a stamping head, a press, a guide plate and a material storage trolley, the unwinding wheel is located at the servo feeding device, the servo feeding device is located on the left side of the press, the guide plate is located on the right side of the press, and the material storage trolley is located below the guide plate.

[0006] The servo feeding device consists of a pair of rollers and a servo motor. The two rollers are parallel to each other and closely attached to each other. The gap in the middle allows the material to pass through. The upper roller is driven to rotate by the servo motor.

[0007] The punching head is located below the press, facing the punching base. The punching head is divided into a punching and trimming punching head and a flanging and cutting punching head. A continuous stamping die is arranged above the punching base. The cross section of the continuous stamping die is in the shape of a door frame, with a gap allowing the material to pass through. The continuous stamping die is divided into a punching and trimming die, a buffer die and a flanging and cutting die in turn. The punching and trimming die and the buffer die are an integral die. The punching and trimming die is provided with a punching and trimming die hole, and the punching and trimming punching head is matched with it. A blanking hole is arranged below the punching base, facing the punching and trimming die hole.

[0008] The length of the buffer mold is exactly the same as the length of an unfolded head. A groove is opened on one side of the buffer mold close to the flanging and cutting mold to bury an air pipe, the air pipe faces the flanging and cutting mold, and the other end of the air pipe is connected to the air pump. The air pump control switch is connected to the servo feeding motor controller.

[0009] The flanging and cutting die is composed of two inverted L-shaped right-angle blocks. The two right-angle blocks are placed opposite to each other in the horizontal direction, and the distance between them in the vertical direction is greater than the width of the unfolded head. A groove is provided on the stamping base directly below the corresponding flanging and cutting die. The specifications of the groove are consistent with the length and width of the largest side of the head. The flanging and cutting punching head matches the groove. A reset plate is provided in the groove of the stamping base, and a unloading spring is provided under the reset plate. The control signal of the press is connected to the servo feeding motor controller.

[0010] The processing technology of the tail leg head automatic stamping equipment specifically adopts the following steps:

[0011] S1, unwinding and feeding, the strip on the unwinding wheel passes through the two rollers of the servo feeding device.

[0012] S2, punching and trimming, then extending to the gap between the continuous stamping die and the stamping base, reaching the range of the punching and trimming die, the press moves downward, and the punching and trimming punching head punches downward to punch the strip trimming.

[0013] S3, continue feeding. After the stamping is completed, the press is reset, and the servo motor drives the roller to rotate. The rotation circumference is just the length of an unfolded head. The strip that has been punched and trimmed enters the buffer mold, and the press repeats the action to punch and cut the second part of the strip. After the press is reset, the servo feeding device continues to work, and the feeding length is still the length of the unfolded head.

[0014] S4, flanging and cutting, the front end of the strip reaches the flanging and cutting die and is placed above the groove. The press drives the punch head composed of the punching and cutting punch head and the flanging and cutting punch head to press down. The flanging and cutting punch head cuts off the connection of the rear section of the strip when punching, and at the same time, the flanging is punched to form a formed head. At the same time, the punching and cutting punch head continues to punch the subsequent strip.

[0015] S5, air blowing separation, the press machine is reset at the same time, the air pump of the air pipe works to supply air, the air pipe blows the formed head with short-term strong airflow, and it falls into the storage trolley along the guide plate.

[0016] S6. Repeat the action. The servo feeding device rotates the specified length to convey the material. At the same time, the air pump works in the air pipe to blow away the forming head. After stopping, the press machine works, and the punching and trimming punch head and the flanging and trimming punch head punch downward.

[0017] The present invention has the following beneficial effects: the entire strip is not separated as a whole before the final flanging and cutting, which is convenient for transmission and advancement, and there will be no directional deviation. In the early stage, the strip is only in the gap between the continuous stamping die and the stamping base, which effectively ensures that there will be no deformation during the stamping process, and the stamping process is more stable. After the stamping is completed, the air pipe is set to discharge air at an instantaneous high pressure to one side of the flanging and cutting die to blow away the stamped head to avoid blocking the channel, and it is also conducive to clearing away the debris generated during the stamping process. The flanging and cutting die is composed of two inverted L-shaped right-angle blocks, which can prevent the strip from deviating without hindering the impact head, and at the same time ensure that the head will not deviate during the blowing process. After the stamping and flanging of the flanging and cutting die is completed, the unloading spring pops up the reset plate to prevent the head from getting stuck in the groove and blocking the process route.
