Description

Technical Field

[0001] The utility model relates to the technical field of die steel, in particular to a hoisting fixture for die steel. Background Art

[0002] Mold steel is a type of steel used to make cold stamping dies, hot forging dies, die-casting dies and other molds. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing process, the precision output of the product and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to reasonable structural design and processing accuracy. Mold steel materials are generally heavy, and during use, the mold steel generally needs to be hoisted to a specified position by a hoist. Therefore, corresponding hoisting fixtures are required for mold steels of different types and shapes.

[0003] Cylindrical mold steel is a common specification. In general, during the hoisting process, the mold steel itself does not have a hoisting ring and cannot be hoisted directly. Therefore, it is more necessary to fix the mold steel with a corresponding clamp before the hoisting operation. In order to hoist the cylindrical mold steel more stably after clamping it, it is necessary to design a hoisting clamp for the mold steel. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] See also Figure 1-3 , a hoisting fixture for mold steel, comprising:

[0028] A main crossbeam 1, with the axis of the main crossbeam 1 parallel to the central axis of the columnar mold steel as the symmetry axis, U-shaped brackets 2 are symmetrically arranged on both sides of the main crossbeam 1, and the number of U-shaped brackets 2 on each side is at least two groups, so as to achieve balanced support for the mold steel, and the upper end of the U-shaped bracket 2 is fixedly connected to the main crossbeam 1;

[0029] An upper clamp 3 is arranged below the main crossbeam 1 and parallel to the main crossbeam 1. A guide hole 4 is provided on the upper clamp 3 for the U-shaped bracket 2 to pass through. The U-shaped bracket 2 slides in the guide hole 4.

[0030] A lower clamp 5, the lower clamp 5 is used to simultaneously pass through the two symmetrical groups of U-shaped brackets 2 on both sides of the main crossbeam 1 so that the two ends of the lower clamp 5 overlap the inner side of the U-shaped bend at the lower ends of the two groups of U-shaped brackets 2, and the columnar mold steel is clamped between the upper clamp 3 and the lower clamp 5; and

[0031] The clamping force applying mechanism is arranged on the main cross beam 1 to apply force to the upper clamp 3 so that the upper clamp 3 is pressed toward the lower clamp 5 to clamp the columnar mold steel between the upper clamp 3 and the lower clamp 5 .

[0032] Specifically, in the process of hoisting, clamping and fixing the mold steel, first, the upper clamp 3 is located directly above the cylindrical mold steel, and the mold steel is placed between the symmetrical U-shaped brackets 2 on both sides of the main beam 1, and then the lower clamp 5 is passed through the two symmetrically distributed groups of U-shaped brackets 2 and fixed to maintain this state, and then the upper clamp 3 is pressed toward the lower clamp 5 through the clamping force mechanism to clamp the columnar mold steel between the upper clamp 3 and the lower clamp 5.

[0033] Furthermore, the lower clamp 5 is a long strip and its lower surface is an arc surface structure corresponding to the inner side of the U-shaped bend at the lower end of the U-shaped bracket 2. The arc surface structure makes it correspond to the shape of the inner side of the U-shaped bend at the lower end of the U-shaped bracket 2, so that the lower clamp 5 and the U-shaped bracket 2 can be better assembled, thereby making the assembly more stable.

[0034] Furthermore, the upper surface of the lower clamp 5 has an arc groove 6 corresponding to the circumferential surface of the columnar mold steel, so that the arc groove 6 contacts the circumferential surface of the columnar mold steel, increasing the contact area with the mold steel, thereby clamping the mold steel more stably.

[0035] Furthermore, both ends of the lower clamp 5 are fastened with the top plate 7 by bolts, so that the two ends of the lower clamp 5 are limited on the two symmetrical groups of U-shaped brackets 2, which plays a limiting role and prevents the lower clamp 5 from detaching from the U-shaped bracket 2.

[0036] Furthermore, the clamping force applying mechanism includes a tightening bolt 8, which is driven downward into the main beam 1 in the vertical direction, and the lower end of the tightening bolt 8 is tightened on the upper surface of the upper clamp 3. Through the threaded cooperation between the tightening bolt 8 and the main beam 1, the upper clamp 3 is tightened to apply the clamping force between the upper clamp 3 and the lower clamp 5.

[0037] Furthermore, two groups of tightening bolts 8 are symmetrically arranged on both sides of each group of U-shaped brackets 2 on the main beam 1, so that the force applied by the clamping force applying mechanism is balanced.

[0038] Furthermore, two groups of lifting rings 9 are symmetrically arranged at both ends of the upper surface of the main cross beam 1, so that the device can be hoisted and the hoisting force is balanced.

[0039] The device can stably clamp and fix the cylindrical mold steel, and the installation operation is convenient and quick, the fixation is more stable and balanced, and the stability and safety of the hoisting of the cylindrical mold steel are better improved.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
