Description

Technical Field

[0001] The invention relates to a transfer tool used in a parts heat treatment process, in particular to a transfer tool for press-quenched parts. Background Art

[0002] Press quenching is the process of rapidly transferring carburized parts to a press quenching die at high temperatures, either manually or mechanically, and cooling them within the mold's constraints to control overall deformation. Transfer, a crucial step in the press quenching process, typically requires a transfer time of no more than 25 seconds, ensuring a smooth and efficient transfer process. Furthermore, since the parts are at high temperatures, the transfer process should be designed to prevent potential risks such as crushing and dropping. Finally, common press quenching parts include ring gears, gears, and various special-shaped products, which vary widely in size, weight, and structure. Therefore, transfer fixtures must be versatile.

[0003] Chinese patent CN215628155U discloses a transfer tool used during quenching, comprising a transfer bracket, a transfer frame, a moving part slidingly arranged on the top of the transfer bracket, and a first driving mechanism arranged on the transfer bracket for driving the moving part, a transfer rod is arranged on the top of the transfer frame, a moving rope and a second driving mechanism for driving the moving rope to rise and fall are arranged on the moving part, and a grabbing mechanism that can automatically grab the transfer rod is arranged at the bottom of the moving rope. Although this patent can use the transfer frame to perform centralized quenching on small workpieces, and the mechanical operation method saves human labor, it occupies a large space and has a complex structure, and is not suitable for use in a narrow working environment; the process of placing parts into the transfer frame still requires manual operation, and placing multiple parts into the transfer frame at the same time can easily cause the parts to be crushed and damaged.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings and embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, an embodiment of the present invention provides a transfer tool for press-quenched parts, including a crossbar 1. The crossbar 1 is generally 1400mm to 1500mm long. In this embodiment, the crossbar 1 is 1500mm long, which facilitates the operator's transfer and walking in a narrow space. A first bracket 2 is provided on the right side of the crossbar 1, and a second bracket 3 is provided on the left side.

[0033] The first bracket 2 is composed of a first cross bar 2a, a second cross bar 2c, a first vertical bar 2b, and a second vertical bar 2d welded together. One end of the first cross bar 2a and the second cross bar 2c are welded to the cross bar 1, and the axes of the two are in the same straight line direction and are perpendicular to the cross bar 1 and parallel to the ground; the other ends of the first cross bar 2a and the second cross bar 2c are respectively welded with a first vertical bar 2b and a second vertical bar 2d pointing vertically downward.

[0034] The second bracket 3 is welded together by a third crossbar 3a, a fourth crossbar 3b, a third vertical bar 3c, a fourth vertical bar 3d, a handle 7, and a sleeve 8. One end of the third crossbar 3a and the fourth crossbar 3b are welded to the sleeve 8, with their axes aligned in a straight line, perpendicular to the sleeve 8, and parallel to the ground. The other ends of the third crossbar 3a and the fourth crossbar 3b are welded to a third vertical bar 3c and a fourth vertical bar 3d, respectively, pointing downward. The handle 7 is welded to the sleeve 8, perpendicular to the sleeve 8 and parallel to the third crossbar 3a. The sleeve 8 is sleeved onto the crossbar 1. During use, a worker can grasp the handle 7 and move the second bracket 3 axially along the crossbar 1 through the sleeve 8 to clamp press-hardened parts of different sizes.

[0035] A limiting plug 6 is provided at one end of the cross bar 1 where the second bracket 3 is provided. The radial dimension of the limiting plug 6 is larger than the inner diameter of the sleeve 8, which can prevent the second bracket 3 from sliding off the cross bar 1. The limiting plug 6 is threadedly connected to the cross bar 1 and can be disassembled.

[0036] The bottom ends of the first vertical rod 2b, the second vertical rod 2d, the third vertical rod 3c and the fourth vertical rod 3d are each provided with a supporting pad 4. Figure 4As shown, the thickness of the rear half of the support gasket 4 is greater than that of the front half, and there is an angle between the upper surface and the lower surface of the front half, the angle range is 10° to 30°, and the angle is selected as 15° in this practical example; the end of the front half of the support gasket 4 is an arc transition; a circular hole 9 is provided near the rear end of the rear half of each support gasket 4.

[0037] The bottom ends of the first vertical rod 2b, the second vertical rod 2d, the third vertical rod 3c and the fourth vertical rod 3d are all inserted into the support gasket 4 through the circular hole 9, and are respectively perpendicular to the support gasket 4, and the two are connected by welding; the axial direction of the support gasket 4 is parallel to the cross bar 1, and the end with an angle and an arc transition faces the opposite side, which is convenient for grabbing the press-quenched parts and not easy to scratch the press-quenched parts.

[0038] The upper surface of one end of each support gasket 4 close to the circular hole is connected to a side gasket 5 by welding. The side surfaces of each side gasket 5 are respectively connected to the first vertical rod 2b, the second vertical rod 2d, the third vertical rod 3c, and the fourth vertical rod 3d by welding, and are perpendicular to the corresponding support gasket 4 and the cross bar 1, thereby increasing the contact area between the tooth top of the press-quenched part and the bracket, and preventing the tooth top of the press-quenched part from being pinched by the bracket.

[0039] When assembling the transfer tooling in this embodiment, first refer to Figure 5 Weld the first bracket 2 to the crossbar 1, and then refer to Figure 1 Weld each support washer 4 to the end of the first vertical rod 2b and the second vertical rod 2d respectively, and weld each side washer 5 to the corresponding support washer 4 and the first vertical rod 2b and the second vertical rod 2d, and ensure stability and reliability;

[0040] Reference Figure 2 After the second bracket 3 is welded, refer to Figure 1 Weld each support pad 4 to the end of the third vertical rod 3c and the fourth vertical rod 3d respectively, and weld each side pad 5 to the corresponding support pad 4 and the third vertical rod 3c and the fourth vertical rod 3d, and ensure stability and reliability; Figure 1 Install it to the left side of the crossbar 1, and then install the upper limit plug 6.

[0041] The transfer tooling is used as follows:

[0042] Two operators hold the left and right sides of the transfer tool respectively, move the crossbar 1, and push the support gasket 4 of the first bracket 2 to the bottom of the press-quenched part to be transferred, so as to support the press-quenched part to be transferred; then the operator on the left holds the handle 7 and pushes the second bracket 3 to the right, and pushes the support gasket 4 of the second bracket 3 to the bottom of the press-quenched part to be transferred, so as to support and clamp the press-quenched part to be transferred. Figure 8As shown; after the part is clamped, it is transferred to the press-quenching die. During the transfer process, the operator on the left needs to continuously apply a certain thrust to the right through the handle 7 to prevent the press-quenched part from falling.
