Description

Technical Field

[0001] This utility model relates to an auxiliary device for riser manufacturing, and more particularly to a device for forming a heating riser for a steering gear housing, belonging to the field of casting processing technology. Background Technology

[0002] The automotive steering system is one of the key systems ensuring vehicle driving safety, and the steering gear housing, as the core load-bearing component of this system, directly affects the stability and safety of vehicle driving. During the casting process of the steering gear housing, the heat-generating riser plays a crucial role; it is a key structure for compensating for the shrinkage of the housing casting, and its molding accuracy and processing efficiency have a significant impact on the entire production process.

[0003] In actual production, the processing flow for small-diameter risers on steering gear housings is relatively complex. First, the riser mold needs to be placed in a slurry tank. Through a vacuum pipe, the slurry is evenly adsorbed onto the outside of the mold, forming a preliminary riser shape. Then, the riser mold containing the slurry is placed at the edge of the slurry tank for further modification and shaping of the riser's outer surface, ensuring that its dimensions and shape meet design requirements.

[0004] However, during this process, when the riser mold is placed at the edge of the slurry pool, the continuous action of the vacuum pipe creates a certain adhesive force between the riser mold and the slurry, resulting in poor stability of the mold at the edge of the slurry pool. In this situation, the riser mold is very likely to slip off the edge of the slurry pool to the ground, which not only damages the riser mold and increases production costs, but also wastes slurry and reduces production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steering gear housing heating riser forming device, which can fix the riser mold, ensure the stability of the mold during the processing, improve processing accuracy and efficiency, ensure production safety, and reduce production costs.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: A steering gear housing heating riser forming device includes a first U-shaped frame, an arc-shaped slot, and a second U-shaped frame. The arc-shaped slot is provided at the bottom of the front end of the first U-shaped frame. Support rods are distributed on both sides above the first U-shaped frame. A first connecting rod is connected to the support rod through a first displacement sleeve. A first guide cylinder is provided at the center of the top of the first connecting rod. An insert rod is inserted into the first guide cylinder. A second U-shaped frame is provided at the end of the insert rod. A third U-shaped frame is provided below the second U-shaped frame.

[0007] The arc-shaped slot is inserted into the edge of the slurry pot and fixed with bolts.

[0008] The first connecting rod has a first displacement sleeve at each end. The first displacement sleeve is fitted onto the support rod and fixed by bolts.

[0009] The insertion rod is fixedly connected to the first guide cylinder by bolts.

[0010] The first U-shaped frame is fitted with second displacement sleeves at both ends, and a second connecting rod is provided between the two second displacement sleeves. A second guide cylinder is provided on both sides of the top of the second connecting rod. A third U-shaped frame passes through the second guide cylinder, and a matching nut is provided at the end of the third U-shaped frame.

[0011] The second displacement sleeve is fixedly connected to the first U-shaped frame by bolts.

[0012] The second U-shaped frame corresponds to the third U-shaped frame on the top and bottom.

[0013] The positive and beneficial effects of this utility model are: 1. This utility model provides a stable support platform for the riser mold by setting a second U-shaped frame at the end of the insert rod. At the same time, with the use of a third U-shaped frame, the vacuum pipe of the riser mold can be limited and fixed, effectively avoiding the safety hazard of the riser mold falling due to shaking or displacement of the vacuum pipe during processing, improving work efficiency and reducing interruptions and rework.

[0014] 2. This utility model provides an arc-shaped slot at the bottom of the front end of the first U-shaped frame and fixes the arc-shaped slot to the slurry tank with bolts, ensuring the stability of the device and making it easy to disassemble and assemble and simple to operate, thus further improving its practicality and convenience.
