Technical Field
[0001] The present invention relates to the technical field of special equipment, and more specifically, to a punching device for mechanical design and manufacture of special equipment. Background Art
[0002] A boiler is a special equipment that can heat water into steam or hot water. When designing and manufacturing a boiler, a bent pipe needs to be connected to the boiler for a through connection. The manufacturing of the bent pipe is to punch a straight pipe into a bent shape through a stamping device. However, the existing stamping device has the following shortcomings when stamping and manufacturing bent pipes: the straight pipe is placed on a stamping support base. Since the middle part of the stamped straight pipe will be deformed, the support base cannot firmly clamp the straight pipe, which causes the straight pipe to easily shift in position during the process of stamping to form the bent pipe, reducing the accuracy of the stamping of the bent pipe. At the same time, the bending angle of the bent pipe after stamping is stuck on both sides of the stamping head with a high degree of fit, making it difficult to remove the bent pipe from the stamping head. Summary of the invention
[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a stamping device for special equipment mechanical design and manufacturing, whose structure includes a bottom plate, a supporting base, supporting columns, a supporting top plate and a stamping mechanism, the bottom plate supports the supporting top plate above by supporting columns arranged at the four corner ends, and the supporting top plate supports the stamping mechanism just above the supporting base which is only arranged on the upper surface of the bottom plate, a placing mechanism is provided at the middle end of the top of the supporting base, and a guide groove is embedded at the side end of the transverse plate arranged on the placing mechanism, a spring pull rod is slidably installed inside the guide groove, and a limit baffle is provided at the outer end of the spring pull rod, the limit baffle clamps the edge of the pipe placed on the side end of the transverse plate, two transverse plates are provided, and are symmetrically installed on the left and right to provide stable support for the pipe as a whole, and the limit baffle can be adjusted by pulling laterally under the elastic sliding cooperation of the spring pull rod and the guide groove.
[0004] As a further improvement of the present invention, the upper end of the limit baffle is also provided with a torsion shaft, a linkage rocker arm and a limiting pressure wheel. The connecting end of the linkage rocker arm and the limit baffle applies elastic torsion through the torsion shaft, and the other end of the linkage rocker arm drives the limiting pressure wheel to contact the inner wall of the pipe. When the torsion shaft applies elastic torsion to the linkage rocker arm, it drives the linkage rocker arm to swing up and down.
[0005] As a further improvement of the present invention, the placement mechanism is also provided with a side connecting plate, a lower groove and a connecting shaft. The lower end of the side connecting plate is connected to the lower groove. The transverse plate is connected by the connecting shaft and swings on the inner side of the side connecting plate as the pipeline is stamped. The lower end of the swinging transverse plate extends into the lower groove. The two transverse plates are connected by the connecting shaft so that the transverse plates on both sides swing at an angle upward to the outside during stamping.
[0006] As a further improvement of the present invention, the punching mechanism is composed of a cylinder, a push rod, a fixed plate, a buffer rod and an air guide, the cylinder applies thrust to the push rod through the support of the support top plate, the push rod is inserted into the support top plate and the fixed plate by a clearance fit, a buffer rod is connected to the edge between the fixed plate and the air guide, and the push rod is arranged in the middle of the upper end of the air guide; An air inlet pipe is embedded inside the air deflector and connected to an external air compressor, and an air collecting cavity is embedded inside the air deflector and is through-connected to the air inlet pipe. The air inside the air collecting cavity is discharged through an air outlet pipe arranged in the middle of the lower end of the air deflector. The air collecting cavity has a spherical structure.
[0007] As a further improvement of the present invention, a punching head is also provided at the lower end of the air deflector, which is locked and fixed to the bottom of the air deflector by bolts arranged on the upper edge, and side protrusions are provided on the front and rear sides of the punching head and are an integrated structure. The diverter groove running through the inside of the punching head is connected to the air outlet pipe, and the air pressure is dispersed to the exhaust mechanism arranged on both sides of the inside of the punching head through the diverter groove.
[0008] As a further improvement of the present invention, the exhaust mechanism includes an exhaust pipe, a protrusion, an air jet pipe, a push rod, a telescopic hose and a push block. The exhaust pipe is embedded in the inside of the punching head, and the protrusion arranged inside the exhaust pipe guides the air pressure to be discharged into the inside of the air jet pipes on both sides. The push rod runs through the inside of the telescopic hose to apply elastic force to the push rod. The push rod elastically moves inside the exhaust pipe to push the push block out of the inside of the punching head. Two exhaust mechanisms are provided, and are symmetrically installed on the left and right sides of the punching head, and are connected to the diversion groove at the same time.
[0009] The beneficial effects of the present invention are: 1. With the elastic cooperation of the guide groove inside the side of the transverse plate and the spring pull rod, the limit baffle can be stretched according to the length of the pipeline, and the limit baffles on both sides can resist and clamp the side ends of pipelines of different lengths under the reset of the spring pull rod. At the same time, the torsion shaft applies elastic torsion to the linkage swing rod, and under the linkage of the linkage swing rod, the limiting pressing wheel can firmly press the inner wall of the pipeline with different inner diameters, thereby improving the firmness of the pipeline fixed on the transverse plate for stamping; 2. After the fixed clamping is completed, the stamping mechanism at the upper end is used to stamp the pipe downward. The middle part of the pipe is bent downward by the stamping force, pushing the transverse plate to swing around the connecting axis. At this time, the outer ends of the transverse plates on both sides are tilted upward and always fit with the two ends of the pipe, thereby improving the bending and forming effect of the pipe; 3. The air pressure is discharged into the diverter slot through the air intake pipe by an external air compressor. Under the dispersion of the diverter slot, the air pressure is evenly discharged into the two exhaust pipes. Under the guidance of the convex block, the air pressure is ejected from the two jet pipes to act on the pipe surface outside the punch head. At the same time, the air pressure pushes the push rod to drive the push block to move outward, exerting thrust on the pipe surface to ensure that the pipe can automatically detach from the punch head after punching, avoiding the punched elbow being stuck with the punch head and difficult to remove.

DETAILED DESCRIPTION
[0017] The present invention is further described below in conjunction with the accompanying drawings: Example
[0018] As attached Figure 1 To Attachment Figure 4 As shown: The present invention discloses a stamping device for designing and manufacturing special equipment machinery, and its structure includes a bottom plate 1, a support base 2, a support column 3, a support top plate 4 and a stamping mechanism 5. The bottom plate 1 supports the support top plate 4 at the top through the support columns 3 arranged at the four corner ends, and the support top plate 4 supports the stamping mechanism 5 just above the support base 2 which is only arranged on the upper surface of the bottom plate 1. A placement mechanism 21 is provided at the middle end of the top of the support base 2, and a guide groove 2131 is embedded at the side end of a transverse placement plate 213 arranged on the placement mechanism 21, and a spring pull rod 2132 is slidably installed inside the guide groove 2131, and the outer end of the spring pull rod 2132 is provided The limit baffle 2133 is used to limit and clamp the edge of the pipe G placed on the side end of the horizontal plate 213. The upper end of the limit baffle 2133 is also provided with a torsion shaft 1331, a linkage swing rod 1332 and a limiting pressure wheel 1333. The connecting end of the linkage swing rod 1332 and the limit baffle 2133 applies elastic torsion through the torsion shaft 1331. The other end of the linkage swing rod 1332 drives the limiting pressure wheel 1333 to contact the inner wall of the pipe G. The placement mechanism 21 is also provided with a side connecting plate 211, a lower groove 212, and a connecting shaft 214. The lower end of the side connecting plate 211 is connected to the lower groove 212. The horizontal plate 2 The connection of the connecting shaft 214 swings on the inner side of the side connecting plate 211 as the pipe G is stamped, and the lower end of the swinging transverse plate 213 extends into the lower groove 212. In the present invention, the pipe G is placed on the two transverse plates 213. During the placement process, the limit baffle 2133 is pulled outward. Under the elastic cooperation of the guide groove 2131 inside the side of the transverse plate 213 and the spring pull rod 2132, the limit baffle 2133 can be stretched according to the length of the pipe G, and under the reset of the spring pull rod 2132, the limit baffles 2133 on both sides are against and clamp the side ends of the pipes G of different lengths. At the same time, the torsion shaft 1331 applies elastic torsion to the linkage rocker 1332, and under the linkage of the linkage rocker 1332, the limiting pressing wheel 1333 firmly presses the inner wall of the pipe G with different inner diameters, thereby improving the firmness of the pipe G fixed on the transverse plate 213 for stamping. After the fixed clamping is completed, the stamping mechanism 5 at the upper end stamps the pipe G downward, and the middle part of the pipe G bends downward after being subjected to the stamping pressure, pushing the transverse plate 213 to swing around the connecting shaft 214.

In the present invention, the push rod 52 is driven by the activated cylinder 51 to apply downward pressure to the air guide 55, and at this time, the punch head 554 at the lower end of the air guide 55 presses the pipe G The stamping work is carried out, and the pipe G after stamping forms a bent pipe state.

Under the dispersion of the diverter groove 5543, the air pressure is evenly discharged into the two exhaust pipes 5441. Under the guidance of the protrusion 5442, the air pressure is ejected from the two jet pipes 5443 to act on the surface of the pipe G outside the punching head 554. At the same time, the air pressure pushes the push rod 5444 to drive the push block 5446 to move outward, applying thrust to the surface of the pipe G, ensuring that the pipe G can automatically detach from the punching head 554 after stamping, avoiding the stamped bent pipe from being stuck with the punching head 554 and being difficult to remove.
