Description

Technical Field

[0001] The utility model relates to the technical field of segment bolt production equipment, in particular to a segment bolt stamping device. Background Art

[0002] Segment bolts are divided into circumferential and longitudinal ones. In some designs, the circumferential and longitudinal specifications are the same, and in some designs, two specifications or even two strength grades are adopted for the circumferential and longitudinal ones. Generally speaking, the length of the circumferential segment bolt is longer than that of the longitudinal segment bolt. In tunnel construction, there is a machine for starting and tunneling called a shield machine, which has functions such as excavating and cutting soil, transporting soil residue, and assembling tunnel linings. However, when the shield machine is lining the tunnel, several segments are assembled. There is a kind of screw that plays a role in connecting and fastening, and a cylindrical pipeline is formed by assembly. The segment is a cylindrical wall. During excavation, it can effectively control ground settlement, reduce the impact on ground buildings, and does not affect surface traffic when excavating underwater, etc. Combining each segment together to form a pipeline, this kind of fastening connector designed as a straight line or with a certain arc is the segment bolt. During the production and processing of the arc-shaped segment bolt, a stamping device is usually required for stamping and forming.

[0003] For the existing segment bolt stamping device, after the segment bolt is stamped and formed, it is easy to embed into the lower die and is not easy to take out. Especially when the segment bolts are batch-stamped, taking out the segment bolts from the lower die one by one will greatly reduce the production and processing efficiency. For example, the utility model patent with the application number 202320363511.4 discloses a subway segment bolt stamping device. This utility model realizes stamping and forming multiple subway segment bolts at one time, speeds up the stamping speed of subway segment bolts, reduces the energy consumption of subway segment bolts during stamping and forming, and improves the efficiency of the stamping device for stamping and forming subway segment bolts.

[0004] However, in this utility model patent, the segment bolts in the stamping model groove of the lower template are stamped by the stamping die body. After stamping, the segment bolts will be embedded in the stamping model groove, and the staff needs to take out the formed segment bolts from the stamping model groove one by one before the next stamping can be carried out, which greatly reduces the production and processing efficiency of segment bolts.

[0005] Therefore, it is necessary to develop a segment bolt stamping device aiming at the above defects. Summary of the Utility Model

[0027] In a specific embodiment, as Figure 1 and Figure 2 shown, it includes a workbench 1. At the four corners of the top surface of the workbench 1, columns 2 are fixedly connected. At the top ends of the columns 2, a mounting plate 3 is fixedly connected. A telescopic member 11 is installed on the mounting plate 3. The telescopic end of the telescopic member 11 is fixedly connected to a mounting seat 4. A plurality of upper templates 5 are fixedly connected to the bottom surface of the mounting seat 4. The upper template 5 is of a cuboid structure and its bottom end protrudes downward in an arc shape. It is characterized in that: a stamping box 6 is fixedly connected to the workbench 1 directly below the upper template 5. The stamping box 6 is hollow inside and has an open top; the top end of the stamping box 6 is detachably connected to a lower template 7. A plurality of stamping model grooves 8 corresponding to the upper templates 5 one by one are provided on the lower template 7; a jacking assembly 9 is slidably connected in the inner cavity of the stamping box 6. A plurality of jacking plates 10 corresponding to the stamping model grooves 8 one by one are fixedly connected to the top end of the jacking assembly 9. The jacking plates 10 are inserted into the stamping model grooves 8. The jacking plates 10 are of a cuboid structure and their top ends are recessed downward in an arc shape with the same radian as the upper template 5.

[0028] The segment bolts placed in the stamping model grooves 8 are stamped and formed by the upper template 5 and the jacking plates 10. The jacking assembly 9 drives the jacking plates 10 to move upward in the stamping model grooves 8, and the segment bolts stamped and formed by the upper template 5 in the stamping model grooves 8 are batch ejected from the stamping model grooves 8, avoiding the need for workers to take out the segment bolts from the stamping model grooves 8 one by one, and improving the production and processing efficiency of the segment bolts.

[0029] In a specific embodiment, as Figures 2 to 5As shown, the jacking assembly 9 includes a moving plate 901 which is slidably connected to the inner wall of the stamping box 6; the moving plate 901 is fixedly connected to the bottom end of the jacking plate 10, and a plurality of compression springs 902 evenly spaced are fixedly connected to the bottom surface of the moving plate 901, and the other ends of the compression springs 902 are fixedly connected to the inner bottom surface of the stamping box 6; compression assemblies and limiting assemblies are arranged at both ends of the moving plate 901.

[0030] The moving plate 901 compresses the compression spring 902 through the compression assembly, and then the position of the moving plate 901 is fixed through the limiting assembly, so that the compression spring 902 remains in a compressed state. Then, the segment bolt is stamped and formed. Finally, the limitation of the moving plate 901 by the limiting assembly is released, and the moving plate 901 drives the moving plate 901 to move upward under the action of the restoring force of the compression spring 902, and finally drives the jacking plate 10 to move upward in the stamping model groove 8 to eject the segment bolt from the stamping model groove 8.

[0031] Specifically, a plurality of guide rods 903 are fixedly connected to the bottom surface of the moving plate 901, the compression springs 902 are sleeved on the guide rods 903, a plurality of guide holes 904 corresponding to the guide rods 903 one by one are formed in the inner bottom surface of the stamping box 6, and the guide rods 903 are inserted into the guide holes 904 and are slidably connected thereto. The movement of the moving plate 901 is guided by the guide rods 903 and the guide holes 904.

[0032] Specifically, the compression assembly includes two pressure rods 905, and corresponding chutes 906 are vertically formed in the side wall of the stamping box 6. One ends of the two pressure rods 905 are fixedly connected to both ends of the same side wall of the moving plate 901, and the other ends penetrate through the chutes 906 and extend out of the stamping box 6. A connecting rod 907 is fixedly connected between the outer ends of the two pressure rods 905, and a pressing plate 908 is fixedly connected to the side wall of the connecting rod 907 away from the stamping box 6.

[0033] By the staff pressing down the pressing plate 908, the connecting rod 907 is driven to drive the pressure rods 905 and the moving plate 901 to move downward, so as to compress the compression spring 902.

[0034] Specifically, the limiting assembly includes a pin 909, and a limiting hole 910 adapted to the pin 909 is formed in the side wall of the stamping box 6 directly above the pressing plate 908, and the pin 909 is inserted into the limiting hole 910. After the moving plate 901 moves downward to compress the compression spring 902, the pin 909 is inserted into the limiting hole 910, and the top surface of the connecting rod 907 abuts against the outer wall of the pin 909 to prevent the moving plate 901 from moving upward, so that the compression spring 902 remains in a compressed state.

[0035] Specifically, a support plate 911 is fixedly connected to the inner wall of the punch box 6, and the support plate 911 is located below the limiting hole 910. The distance between the top surface of the support plate 911 and the bottom end of the limiting hole 910 is the same as the distance between the top surface of the connecting rod 907 and the bottom surface of the moving plate 901. It can ensure that when the support plate 911 supports the moving plate 901, the top surface of the connecting rod 907 can contact the outer wall of the latch 909.

[0036] In a specific embodiment, the telescopic member 11 is a hydraulic cylinder, an electric push rod, an electro-hydraulic push rod or a gas cylinder.

[0037] Working principle: When the segment bolt punching device of the utility model is used, the staff first presses the pressing plate 908 downward, drives the connecting rod 907 to drive the pressing rod 905 and the movable plate 901 to move downward, thereby compressing the compression spring 902 until the bottom surface of the movable plate 901 contacts the top surface of the support plate 911, and then inserts the latch 909 into the limiting hole 910, and the connecting rod 907 abuts against the outer wall of the latch 909 to keep the compression spring 902 in a compressed state. Then, the segment bolts are respectively placed into the punching model slots 8, the telescopic end of the telescopic member 11 is controlled to extend, the mounting seat 4 is driven to drive the upper template 5 to move downward, and the segment bolts are punched and formed by cooperating with the jacking plate 10. After the segment bolts are stamped and formed, the telescopic end of the telescopic part 11 is controlled to shorten, and the mounting seat 4 is driven to drive the upper template 5 to move up and away from the lower template 7, and then the pin 909 is pulled out. Under the action of the restoring force of the compression spring 902, the movable plate 901 is driven to move upward, and the lifting plate 10 is driven to move upward in the stamping model groove 8, and the formed segment bolts are pushed out of the stamping model groove 8. Finally, the segment bolts are collected by the staff, and the next stamping operation can be carried out according to the above steps.
