Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a tooling fixture for roller forging. Background Art

[0002] The wheel hub of a car roller is a cylindrical metal part with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a wheel rim, steel rim, wheel, or tire bell. In order to improve the strength, toughness, and firmness of the wheel hub, forging is often used to prepare the wheel hub.

[0003] After the automobile wheel hub is forged, it needs to be clamped out of the forging machine. A clamp is needed during the clamping process. However, the existing clamps are generally used to clamp automobile wheels of fixed thickness. If the thickness is different, the clamp needs to be replaced. As a result, multiple clamps need to be configured to produce wheels of different thicknesses, which wastes resources to a great extent. Utility Model Content

DETAILED DESCRIPTION

[0021] Example 1

[0022] A roller forging fixture, such as Figure 1 and Figure 2 As shown, it includes a fixed base 100, a telescopic rod 130 rotatably mounted on the fixed base 100, a horizontal telescopic part arranged at the telescopic end of the telescopic rod 130, and a first clamping plate 110 and a second clamping plate 120 installed on the side wall of the horizontal telescopic part from top to bottom, and a driving mechanism for driving the first clamping plate 110 to perform vertical displacement.

[0023] Working principle: metal material is placed in a forging machine (existing technology) for forging, and after forging, a car wheel hub blank with a certain thickness and extremely high temperature is formed. Since the car wheel hub blank also needs to undergo subsequent heat treatment processing, such as edge grinding, etc., it is necessary to take it out of the forging machine. Specifically, the telescopic rod 130 is rotated to align the first clamping plate 110 and the second clamping plate 120 with the direction of the car wheel hub blank. Thereafter, the driving mechanism is opened to drive the second clamping plate 120 to move downward until the distance between the second clamping plate 110 and the first clamping plate 110 is just matched with the thickness of the car wheel hub blank. Thereafter, the horizontal telescopic part is started to move the first clamping plate 110 and the second clamping plate 120 along the direction of the car wheel hub blank until the car wheel hub blank is clamped. Thereafter, the horizontal telescopic part is contracted, and the telescopic rod 130 is rotated to connect the two clamping plates to the car wheel hub blank for rotation, so as to transfer the car wheel hub blank to the docking device of the next processing area.

[0024] Further, such as Figure 1 and Figure 2As shown, the horizontal telescopic part includes a hydraulic rod 300 horizontally arranged at the telescopic end of the telescopic rod 130, and a connecting block 140 arranged at the telescopic end of the hydraulic rod 300; the first clamping plate 110 and the second clamping plate 120 are arranged on the side wall of the connecting block 140; in order to support the connecting block 140, the side wall of the telescopic rod 130 is also provided with a supporting plate 310, the bottom end of the connecting block 140 is slidably connected to the top surface of the supporting plate 310 (existing technology), and the second clamping plate 120 can be slidably connected to the supporting plate 310, or can be set with a gap. In specific implementation, when it is necessary to clamp the automobile wheel hub blank, the hydraulic rod 300 is started to make the connecting block 140, the first clamping plate 110 and the second clamping plate 120 synchronously face the direction of the automobile wheel hub blank, so as to achieve the purpose of clamping the automobile wheel hub blank.

[0025] Further, such as Figure 1 and Figure 2 As shown, the telescopic rod 130 includes an outer rod 131 connected to the fixing seat 100, an inner rod 132 arranged inside the outer rod 131, a first plug hole is penetrated through the side wall of the outer rod 131, and a plurality of second plug holes matching the first plug holes are arranged on the side wall of the inner rod 132 from top to bottom, and a first bolt 150 is horizontally arranged between the first plug hole and the second plug holes matching therewith. Among them, the inner rod 132 is a square rod. In specific implementation, when it is necessary to adjust the height of the telescopic rod 130, the inner rod 132 is vertically displaced inside the outer rod 131. After the displacement is completed, the first bolt 150 is added to the first plug hole and the second plug hole matching the first plug hole to achieve the purpose of limiting the inner rod 132 to the inside of the outer rod 131.

[0026] Further, such as Figure 1 , 2 and Figure 4 As shown, the driving mechanism includes a motor seat 160 arranged on the connecting block 140, a motor arranged on the motor seat 160, and a screw rod 170 vertically passing through the first clamping plate 110 and connected to the output end of the motor. In order to improve the stability of the vertical displacement of the first clamping plate 110, in actual implementation, as shown in FIG. Figure 1 and Figure 2 As shown, a threaded auxiliary sleeve 220 adapted to the screw rod 170 may be provided at the top of the first clamping plate 110; the first clamping plate 110 is slidably connected to the side wall of the connecting block 140. Figure 2 and Figure 3As shown, a slider 180 is provided at one end of the first clamping plate 110 close to the connecting block 140, and a vertical slide groove 190 is provided on the connecting block 140 to slide with the slider 180. In specific implementation, when the height of the first clamping plate 110 needs to be adjusted, the motor is started to rotate the screw rod 170, and during the rotation process, the slider 180 slides in the vertical slide groove 190, thereby adjusting the height of the first clamping plate 110.

[0027] Furthermore, since the automobile wheel hub blank is in a high temperature environment after forging, the high temperature environment has a certain influence on the motor performance. Based on this, the motor seat 160 is made of heat-insulating material. Furthermore, in order to minimize the influence of the motor on the high temperature environment, Figure 2 As shown, the side wall of the motor seat 160 is provided with a heat shield 200, and the heat shield 200 is provided with a heat dissipation port for heat dissipation of the motor on one side (i.e., the right side) close to the telescopic rod 130. Figure 4 As shown, the heat shield 200 and the motor base 160 are connected by a second bolt 210 to facilitate disassembly of the heat shield 200 .
