Description

Technical Field

[0001] The present application belongs to the field of head stamping, and more specifically, relates to a head forming hydraulic press. Background Art

[0002] In the metal processing and manufacturing industry, head stamping is a crucial process, which is widely used in the production of heads used in pressure vessels, piping systems, chemical equipment and other fields. Traditional head stamping technology mainly fixes the metal sheet through the edge clamping ring beam, and then applies high pressure through the hydraulic cylinder to stamp the metal sheet into the required shape of the head. Since different head sizes require edge clamping ring beams of different diameters to fix them, and due to the design limitations of traditional stamping machines, edge clamping ring beams of different inner diameters must maintain the same outer diameter size to be installed and fixed, which will make the edge clamping ring beam with a small inner diameter too heavy, which greatly affects the replacement efficiency of the edge clamping ring beam and wastes metal materials. At the same time, the edge clamping force position of the edge clamping ring beam with a small inner diameter is far away from the position of the loading force, and the edge clamping effect is not good. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a head forming hydraulic press to solve the technical problem of inconvenient replacement of the edge pressure ring beam in the prior art.

[0014] Optionally, the end of the piston rod forms a receiving cavity, and the head forming hydraulic press further comprises a flange head threadedly connected to the side wall of the receiving cavity, a connecting block detachably connected to the pressure ring beam, and a connecting rod passing through the flange head and threadedly connected to the connecting block;

[0015] One end of the connecting rod away from the connecting block extends into the accommodating cavity and abuts against the end surface of the flange head so that a gap is formed between the connecting block and the flange head in the axial direction of the piston rod.

[0032] Please also read Figures 1 to 4 Now, a head forming hydraulic press provided in the embodiment of the present application is described. The head forming hydraulic press comprises a top box beam 101, a main cylinder 102, a pressure cylinder 104, a driving mechanism and a pressure ring beam 106. Among them:

[0033] The main cylinder 102 is connected to the top box beam 101 and is connected to a slider 103 at the power output end, which can drive the slider 103 to move for stamping operations. Multiple edge-pressing cylinders 104 are evenly arranged around the main cylinder 102 and pass through the slider 103. The slider 103 is provided with a notch 105 extending toward the central axis of the main cylinder 102 and for the edge-pressing cylinder 104 to move. The driving mechanism is connected to the edge-pressing cylinder 104 by transmission and is used to drive the edge-pressing cylinder 104 to move along the extension direction of the notch 105. The edge-pressing ring beam 106 is detachably connected to the end of the piston rod 107 of all the edge-pressing cylinders 104. In this embodiment, the edge-pressing ring beam 106 is connected to the end of the piston rod 107 of the edge-pressing cylinder 104 and is used to press the edge of the workpiece to be stamped under the drive of the edge-pressing cylinder 104 to facilitate the stamping operation of the main cylinder 102.

[0034] According to the above structure provided in the present embodiment, in the head forming hydraulic press provided in the present embodiment, the side pressing cylinder 104 for connecting the side pressing ring beam 106 is evenly arranged around the main cylinder 102 and passes through the slider 103 connected to the power end of the main cylinder 102. Since the slider 103 is provided with a slot 105 extending toward the central axis of the main cylinder 102 and the side pressing cylinder 104 is transmission-connected with a driving mechanism for driving the side pressing cylinder 104 to move along the extension direction of the slot 105, under the adjustment action of the driving mechanism, the ends of the piston rods 107 of the plurality of side pressing cylinders 104 can be coordinated and distributed in the circumferential direction of different positions and radial sizes. In this way, the plurality of side pressing cylinders 104 can adjust the pressure center well and adapt to the side pressing ring beams 106 of different outer diameters, which is beneficial to significantly reduce the outer diameter size and its own weight of the side pressing ring beam 106 and significantly reduce the difficulty of replacing the side pressing ring beam 106, which is far superior to the prior art. In addition, the edge holding ring beam 106 with a reduced outer diameter can also significantly reduce manufacturing costs and is suitable for a larger stamping forming range. The edge holding effect during head forming is better, which is conducive to achieving greater economic benefits for the head forming hydraulic press provided in this embodiment.

[0035] In another embodiment of the present application, please refer to Figures 1 to 4 , the driving mechanism includes a support 108 connected to the top box beam 101, a ball screw 109 rotatably mounted on the support 108, and a nut 110 threadedly connected to the ball screw 109. The support 108 is also provided with a slide groove 111 parallel to the ball screw 109. In this embodiment, the driving mechanism also includes a pressure-bearing sliding seat 112 arranged in the slide groove 111 and slidably connected to the support 108, the pressure-bearing sliding seat 112 is connected to the nut 110, and the edge pressing cylinder 104 is connected to the pressure-bearing sliding seat 112. According to the above structure provided in this embodiment, when the ball screw 109 rotates, the nut 110 threadedly connected to the ball screw 109 can be driven to move along the axial direction of the ball screw 109. Since the pressure-bearing sliding seat 112 arranged in the slide groove 111 is connected to the nut 110, when the nut 110 moves, the pressure-bearing sliding seat 112 can be driven to move in the slide groove 111. In this way, the edge holding cylinder 104 connected to the pressure-bearing sliding seat 112 can move in the groove 105 set on the slider 103 following the pressure-bearing sliding seat 112, thereby achieving the technical effect of adjusting the end position of the piston rod 107 of the edge holding cylinder 104 to adapt to the edge holding ring beam 106 with different outer diameters, and has a stable and precise adjustment effect.

[0036] In another embodiment of the present application, please refer to Figures 1 to 4The driving mechanism also includes a servo reduction motor 113 mounted on the support 108, and the ball screw 109 is connected to the power output end of the servo reduction motor 113 and driven by the servo reduction motor 113 to rotate around its own central axis. According to the above structure provided in this embodiment, the use of the servo reduction motor 113 to drive the ball screw 109 to rotate can further improve the automation level of the head forming hydraulic press in this embodiment.

The end of the connecting rod 117 away from the connecting block 116 extends into the accommodating chamber 114 and abuts against the end face of the flange head 115 so that a gap is formed between the connecting block 116 and the flange head 115 in the axial direction of the piston rod 107. According to the above structure provided in the present embodiment, since the connecting block 116 abuts against the end face of the flange head 115 through the connecting rod 117 and forms a gap with the flange head 115 in the axial direction of the piston rod 107, when it is necessary to remove the pressure ring beam 106, the gap between the connecting block 116 and the flange head 115 can be used to lift the connecting block 116 in the axial direction of the piston rod 107 and significantly reduce the clamping force between the connecting rod 117 and the connecting block 116, which is conducive to easier removal of the connecting block 116 from the connecting rod 117; and when the pressure ring beam 106 is needed to clamp the workpiece to be stamped, the flange head 115 can be lowered to directly abut against the connecting block 116, so that the connecting block 116 as a whole bears the stamping force from the pressure cylinder 104, which is conducive to the long-term and stable operation of the head forming hydraulic press provided in the present embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 4 A thrust bearing 118 is coaxially sleeved on the connecting rod 117, and the connecting rod 117 abuts against the flange head 115 through the thrust bearing 118. According to the above structure provided in this embodiment, by providing the thrust bearing 118 between the connecting rod 117 and the flange head 115, the connecting rod 117 can be more stably connected to the flange head 115.

[0039] In another embodiment of the present application, please refer to Figures 1 to 4The connecting block 116 forms a connecting threaded hole 119 and a locking threaded hole 120 that are vertically connected, and the connecting block 116 is threadedly connected to the connecting rod 117 through the connecting threaded hole 119. According to the above structure provided in this embodiment, the locking threaded hole 120 can be used to install a fastener (not shown in the drawings), so that when the fastener is installed in the locking threaded hole 120 and extends from the locking threaded hole 120 into the connecting threaded hole 119, it can abut against the connecting rod 117 installed in the connecting threaded hole 119 and form a more stable connection between the connecting rod 117 and the connecting block 116.

[0040] In another embodiment of the present application, please refer to Figures 1 to 4 , the end of the connection block 116 away from the flange head 115 forms a cavity 121, and the head forming hydraulic press also includes a connection seat 122 connected to the pressure ring beam 106, the connection seat 122 forms a connection ear 123 extending into the cavity 121, and the connection seat 122 is connected to the connection block 116 through a pin 124 that can pass through the connection ear 123 and the connection block 116. According to the above structure provided in this embodiment, by passing through the pin 124 of the connection ear 123 and the connection block 116, the connection seat 122 and the connection block 116 can be quickly connected, and the two can be quickly disassembled, which is conducive to further reducing the difficulty of replacing the pressure ring beam 106 in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 4 The connecting ear 123 is provided with a waist-shaped hole 125 for the pin shaft 124 to pass through. The connecting ear 123 is overlapped on the pin shaft 124 through the waist-shaped hole 125 and forms a gap between the connecting seat 122 and the connecting block 116 in the axial direction of the piston rod 107. According to the above structure provided in the present embodiment, since a gap is formed between the connecting seat 122 and the connecting block 116 in the axial direction of the piston rod 107, when it is necessary to remove the pressure ring beam 106, the connecting seat 122 can be lifted in the axial direction of the piston rod 107 by utilizing the gap between the connecting seat 122 and the connecting block 116, thereby reducing the clamping force between the connecting seat 122 and the connecting block 116, which is conducive to more easily removing the connecting seat 122 from the connecting block 116; and when the pressure ring beam 106 is needed to clamp the part to be stamped, the connecting block 116 can be lowered to directly abut against the connecting seat 122, so that the connecting seat 122 as a whole bears the stamping force from the pressure cylinder 104, which is conducive to making the head forming hydraulic press provided in the present embodiment operate more stably for a longer period of time.
