Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel head processing, and in particular relates to a punching machine used for producing pressure vessel heads. Background Art

[0002] The pressure vessel head refers to the component used to seal the end of the pressure vessel to isolate the internal and external media, also known as the end cover. According to the shape of the head surface, it can be divided into convex, conical, flat and combined shapes. At present, the pressure vessel head needs to be processed and punched by a special punching machine used for the production of pressure vessel heads;

[0003] The existing punching machines for producing pressure vessel heads are usually composed of a cylinder, a punch and a support seat. The cylinder serves as a driving source to drive the punch downward, and the support seat supports the pressure vessel head, thereby punching the pressure vessel head. Although the punching operation of the pressure vessel head can be realized, there are still some problems in use. Since the opening in the middle of the support seat is poorly compatible with the punch, when holes of different diameters need to be processed, the support seat has weak support for the edge of the punching position of the pressure vessel head, which will cause deformation of the edge of the punching position of the pressure vessel head when punching, affecting the quality of the pressure vessel head after punching, and the pressure vessel head needs to be corrected after punching. Secondly, it is not convenient to support pressure vessel heads of different specifications and depths, and requires repeated manual adjustments. Utility Model Content

[0004] In view of this, the utility model provides a punching machine for producing pressure vessel heads, which can meet the needs of punching support for pressure vessel heads of different specifications and depths through a supporting mechanism. It does not require repeated manual adjustment and can provide support to the edge of the punching position of the pressure vessel head to the greatest extent, thereby avoiding deformation of the edge of the punching position of the pressure vessel head during punching, thereby improving the quality of the pressure vessel head after punching and reducing the probability of the pressure vessel head needing correction after punching.

[0005] In order to solve the above technical problems, the utility model provides a punching machine for producing pressure vessel heads, including a workbench and a supporting mechanism arranged on the workbench, the supporting mechanism including electric telescopic rods evenly arranged in a ring shape in the middle of the workbench, an annular support plate is provided between the telescopic ends of the three electric telescopic rods, a supporting die head is fixedly installed on the upper end surface of the annular support plate by bolts, and an adjustment component is threadedly connected to the inner thread of a screw hole arranged in the middle of the supporting die head.

[0006] The supporting mechanism also includes rectangular limiting blocks which are evenly arranged on the upper end surface of the annular supporting plate in an annular shape, and the lower end surface of the supporting die head is provided with rectangular slots which correspond one to one with the rectangular limiting blocks.

[0007] The supporting mechanism also includes pressure sensors which are evenly arranged in a ring shape at the middle of the upper end of the supporting die head, and the pressure sensors are all electrically connected to the external single chip computer.

[0008] The upper edge of the workbench is provided with annular grooves evenly distributed.

[0009] The adjusting component comprises a supporting ring which is threadedly connected in the screw hole, and the upper end surface of the supporting ring is provided with circular grooves which are evenly distributed in an annular shape.

[0010] A mounting frame is provided at the right end of the workbench, a cylinder is provided on the left side of the upper end of the mounting frame, a connecting seat is provided at the lower end of the telescopic end of the cylinder, a punching head is installed on the internal thread of the connecting seat, the punching head is matched with the support ring, and the cylinder is electrically connected to the external single-chip computer; a discharge port corresponding to the support ring is provided in the middle of the workbench.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] First, the relevant staff will replace the corresponding supporting die head according to the specifications of the pressure vessel head, and then place the pressure vessel head to be punched at the center of the workbench. Then the relevant staff will control the synchronous operation of the electric telescopic rod through the external single-chip microcomputer. The upward movement of the telescopic end of the electric telescopic rod will drive the annular support plate, supporting die head, pressure sensor, rectangular limit block, support ring and circular groove to move upward synchronously. In this process, the detection terminal of the pressure sensor will first contact the pressure vessel head. At this time, the pressure sensor will detect the contact pressure and synchronize the detection data to the external single-chip microcomputer. When the machine determines that the pressure reaches the threshold, the external single-chip microcomputer controls the electric telescopic rod to stop operating. At this time, the support die head and the support ring form a whole to provide support for the pressure vessel head, meeting the needs of punching support for pressure vessel heads of different specifications and depths, without the need for repeated manual adjustments. At the same time, since the support ring is matched with the punching head, it can provide support to the edge of the punching position of the pressure vessel head to the greatest extent, thereby avoiding deformation of the edge of the punching position when the pressure vessel head is punched, thereby improving the quality of the pressure vessel head after punching and reducing the probability of correction after the pressure vessel head is punched. The external single-chip microcomputer controls the operation of the cylinder, and the downward movement of the telescopic end of the cylinder drives the connecting seat and the punching head to move downward synchronously, and finally the punching head completes the punching operation of the pressure vessel head. When it is necessary to punch holes of different diameters on the pressure vessel head, the relevant staff only needs to remove the punching head and the support ring counterclockwise in turn, and then replace the punching head and support ring of the matching diameter, which is convenient for the relevant staff to quickly replace.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described.

Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0019] like Figure 1-4 As shown:

[0020] The present embodiment provides a punching machine for producing pressure vessel heads, including a workbench 100 and a supporting mechanism arranged on the workbench 100, the supporting mechanism including electric telescopic rods 200 evenly arranged in an annular shape in the middle of the workbench 100, an annular supporting plate 201 is arranged between the telescopic ends of the three electric telescopic rods 200, a supporting die head 202 is fixedly installed on the upper end surface of the annular supporting plate 201 by bolts, and an adjusting component is connected to the inner thread of a screw hole arranged in the middle of the supporting die head 202; the supporting mechanism also includes pressure sensors 203 evenly arranged in an annular shape in the middle of the upper end of the supporting die head 202, and the pressure sensors 203 are electrically connected to an external single-chip computer; the supporting mechanism also includes rectangular limit blocks 204 evenly arranged in an annular shape on the upper end surface of the annular supporting plate 201, and a rectangular slot corresponding to the rectangular limit blocks 204 is arranged on the lower end surface of the supporting die head 202.

[0021] like Figure 1-4 As shown, the adjustment assembly includes a support ring 300 threadedly connected to the screw hole, and the upper end surface of the support ring 300 is provided with circular grooves 301 evenly distributed in an annular shape.

[0022] like Figure 1-3As shown, a mounting frame 600 is provided at the right end of the workbench 100, a cylinder 601 is provided at the left side of the upper end of the mounting frame 600, a connecting seat 602 is provided at the lower end of the telescopic end of the cylinder 601, a punching head 603 is installed on the internal thread of the connecting seat 602, the punching head 603 is arranged in conjunction with the support ring 300, and the cylinder 601 is electrically connected to the external single-chip computer.

[0023] like Figure 2-4 As shown, a discharge port 400 corresponding to the support ring 300 is provided in the middle of the workbench 100 .

[0024] The working principle of a punching machine for producing pressure vessel heads provided by the utility model is as follows: first, relevant staff replaces a corresponding supporting die head 202 according to the specifications of the pressure vessel head, and then places the pressure vessel head to be punched at the center of the workbench 100. Then, relevant staff regulates the synchronous operation of the electric telescopic rod 200 through an external single-chip microcomputer. The upward movement of the telescopic end of the electric telescopic rod 200 drives the annular support plate 201, the supporting die head 202, the pressure sensor 203, the rectangular limit block 204, the support ring 300 and the circular groove 301 to move upward synchronously. During this process, the detection terminal of the pressure sensor 203 will first contact the pressure vessel head. At this time, the pressure sensor 203 detects the contact pressure and synchronizes the detected data to the external single-chip microcomputer. When the external single-chip microcomputer determines that the pressure reaches the threshold value, the external single-chip microcomputer regulates the electric telescopic rod 200 to stop operating. At this time, the whole composed of the supporting die head 202 and the support ring 300 is the pressure vessel head. The head provides support to meet the needs of punching support for pressure vessel heads of different specifications and depths without repeated manual adjustment. At the same time, since the support ring 300 is matched with the punching head 603, it can provide support to the edge of the punching position of the pressure vessel head to the greatest extent, thereby avoiding deformation of the edge of the punching position of the pressure vessel head when punching the pressure vessel head, thereby improving the quality of the pressure vessel head after punching and reducing the probability of correction required after punching the pressure vessel head. After the adjustment is completed, the external single-chip microcomputer controls the operation of the cylinder 601, and the telescopic end of the cylinder 601 moves downward to drive the connecting seat 602 and the punching head 603 to move downward synchronously, so that the punching head 603 finally completes the punching operation of the pressure vessel head. When it is necessary to punch holes of different diameters on the pressure vessel head, the relevant staff only needs to remove the punching head 603 and the support ring 300 counterclockwise in turn, and then replace the punching head 603 and the support ring 300 of the matching diameter, which is convenient for the relevant staff to quickly replace.

[0025] like Figure 1-4 As shown, an annular evenly distributed groove 500 is provided at the upper edge of the workbench 100 .

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
