Description

Technical Field

[0001] This utility model belongs to the technical field of mold moving arm devices, specifically, it relates to a mold moving arm device for a precision forging machine. Background Technology

[0002] Precision forging refers to a forging process that produces complex shapes and high-precision forgings on forging equipment. An example is precision forged bevel gears, where the tooth profile can be forged directly without further machining. In the operation of a precision forging machine, the die is an essential forging component. During processing, different forging dies need to be replaced as the product model changes. Due to the structural limitations of forging equipment, it is difficult to directly lift the die using hoisting equipment. Therefore, a die-shifting arm structure is needed. Application No. CN201620467492.X discloses a heavy-duty mobile die-shifting arm. By adjusting the feet, the height of the heavy-duty mobile die-shifting arm is adjusted so that it is on the same horizontal plane as the punch press. When the heavy die is placed on this heavy-duty mobile die-shifting arm, the adjusting feet provide support, reducing the torque at the connection between the heavy-duty mobile die-shifting arm and the punch press, enhancing the stability of the heavy-duty mobile die-shifting arm, and ensuring that it will not deform or break. It has a certain practical effect for die replacement. However, because there are no effective limiting measures on both sides of the device, there is a risk of die tilting or even falling due to instability during use, posing a certain safety hazard.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0028] The outer side of the section where the side limit seat 5 and the limit adjustment seat 8 cooperate is provided with scale lines. By observing the scale lines, the extension and retraction of the side limit seats 5 on both sides are kept consistent.

[0029] The moving mold arm support rail 2 is provided with an installation groove 3. A support roller 4 is rotatably connected and installed in the installation groove 3. Multiple support rollers 4 are arranged along the length of the installation groove 3. The support of the support rollers 4 is flush with the upper plane of the extension connecting plate 21 to ensure the support effect of the support rollers 4.

[0030] The end of the mold moving arm support rail 2 away from the connecting mating seat 20 is rotatably connected to and installed with a limiting end block 15 via an end block adjusting shaft 16.

[0033] The working principle of this utility model is as follows: When using the mold shifting arm device, firstly, the connecting mating seat 20 is fixedly installed on the outside of the worktable of the main body 1 of the forging machine. The connecting mating seat 20 is installed with countersunk bolts to avoid interference during the installation of the mold shifting arm support rail 2. The end of the mold shifting arm support rail 2 with the extension connecting plate 21 is connected to the connecting mating seat 20. The connecting mating seat 20 is provided with a limit mating block 22, and the mold shifting arm support rail 2 is provided with a matching mating groove for the limit mating block 22. Through the cooperation of the extension connecting plate 21 and the connecting mating groove 25, and the cooperation of the limit mating block 22 and the mating groove provided below the mold shifting arm support rail 2, the installation of the mold shifting arm support rail 2 can be effectively limited and positioned.

[0034] When installing the mold on the worktable of the forging machine body 1, the limiting end block 15 is rotated and adjusted until the upper plane is in a horizontal state, so that the mold can be moved and placed on the mold moving arm support rail 2.

During the movement of the mold along the mold moving arm support rail 2, the side limiting wheels 7 can effectively limit the two sides of the mold to prevent the mold from tilting during the movement process, which is safe.

[0036] The spacing between the two limit frames 6 can be adjusted as needed to adapt to the needs of different specifications of molds. The fit between the adjustable support column 11 and the lower support column 10 can be adjusted to meet the needs of different specifications of forging machine body 1 and operating environment.

[0037] This utility model has a reasonable structural design and is easy to install and use. The installation and adjustment process of the mold-moving arm support rail 2 does not require complicated tools. The mold-moving arm support rail 2 and the side limiting frame 6 are respectively equipped with support rollers 4 and side limiting wheels 7. During the mold movement process, the rolling friction position is used, resulting in low friction. The connection position between the mold-moving arm support rail 2 and the forging machine body 1 is equipped with a connecting mating seat 20, a limiting mating block 22, an extension connecting plate 21, and a connecting mating groove 25, which effectively improves the accuracy and stability of the fit between the mold-moving arm support rail 2 and the forging machine body 1. The mold-moving arm device is equipped with two sets of mold-moving arm support rails 2, which improves the stability of the device support. At the same time, the side limiting frame 6 and the side limiting wheel 7, which can be adjusted in position, are provided on the outside of the mold-moving arm support rail 2. During the mold movement process, the two sides can be effectively limited to ensure the stability of the mold movement process and improve the safety of the mold-moving arm.
