Embodiment 1

[0047] Such as Figure 1-Figure 3Shown is a schematic structural diagram of a vehicle front panel seat in the prior art, the front panel seat includes a base 101, a back panel 102 is provided on one side of the base 101, and four vertical panels are evenly spaced on the base 101 103 is connected to the back plate 102, and the two sides of the back plate 102 are symmetrically provided with fixing holes 104, and the base 101 is provided with a plurality of mounting holes 105 distributed in strips between two adjacent vertical plates 103, and a plurality of The mounting holes 105 are evenly spaced. In practice, the processing accuracy requirements for the mounting holes 105 and the fixing holes 104 are relatively high, especially for multiple closely arranged mounting holes 105, the dimensional processing tolerance is required to be between ±0.5mm, and the surface quality of the hole walls is extremely high. The advanced lost foam casting technology is difficult to accurately co...

Embodiment 2

[0058] The preparation process of a vehicle front panel seat of this embodiment is basically the same as that of Embodiment 1. Furthermore, the design of the gating system in this embodiment cannot be ignored, such as Figure 4 As shown, the gating system in this embodiment includes a sprue 300, a runner, and a sprue connected in sequence. The sprue is connected to the foam pattern, and the top of the sprue 300 is provided with a sprue whose opening size tapers downward. The spout cup 200, wherein the sprue cup 200 is a non-axisymmetric structure. During pouring, the molten steel is poured from the sprue cup 200, and enters the foam pattern through the sprue 300, the runner and the sprue in turn. The industry usually adopts a conical or funnel-shaped gate with good diversion effect. Cup 200, but in practical application, molten steel is still prone to problems such as impurities and oxidation, and casting defects such as slag inclusions and pores will still be formed in castin...

Embodiment 3

[0062] The preparation process of a vehicle frontal plate seat of this embodiment is basically the same as that of Embodiment 2. Furthermore, the bottom of the sprue 300 in this embodiment is also provided with a filter screen 302 made of ceramic material, such as Figure 5 As shown, specifically, the bottom of the sprue 300 is provided with an upper connection section 301 whose opening size gradually expands from top to bottom, and a lower connection section 303 with an opening size that gradually shrinks from top to bottom is provided below the upper connection section 301. 302 is disposed between the upper connection section 301 and the lower connection section 303 . The diameter of the filter screen 302 is at least twice (in this embodiment, twice) the inner diameter of the sprue 300. The filter screen 302 is evenly provided with filter holes, and the diameter of the filter holes is 2-4mm. The spacing (the spacing between the walls of two adjacent filter holes) is 5-6mm. ...

Abstract

The invention discloses a manufacturing process for a vehicle front draft lug, and belongs to the field of casting processing. The manufacturing process comprises the following steps: step I, smeltingmolten steel which comprises the following components in percentage by weight: 0.25-0.3% of C, 0.2-0.5% of Si, 0.5-0.9% of Mn, 0.4-0.5% of Ni and 0.3-0.4% of Cu; step II, manufacturing a foam mould sample and a casting system, and vibrating and compacting the foam mould sample and the casting system in a sand box, wherein the casting system comprises a straight pouring gate, a transverse pouringgate and a branch pouring gate, the branch pouring gate is connected with the foam mould sample, and a non-axisymmetric pouring cup is arranged on the top of the straight pouring gate; step III, casting the smelted molten steel for enabling the foam mould sample in the sand box to lose and to form a casting; and step IV, cooling the casting, and taking out the casting to clear. The manufacturingprocess overcomes the defects such as high labor intensity and low processing efficiency of the vehicle front draft lug in the prior art, effectively reduces processing labor intensity, improves processing efficiency, avoids structural deformation of the front drug lug, guarantees processing precision, and effectively increases the product processing qualification rate.

Description

technical field [0001] The invention relates to the technical field of pouring processing, more specifically, to a preparation process of a vehicle front panel seat. Background technique [0002] The front slave plate seat is a part of the vehicle buffer device. It is an important force-bearing part for the traction and braking buffer of the vehicle. Its machining accuracy has a great impact on its performance. At present, mechanical processing is generally used for the processing of the front board seat, but the machining has the disadvantages of low processing precision, high processing labor intensity, and low processing efficiency, and it is difficult to process the front board by using the ordinary lost foam casting process. Due to the structural requirements of the seat, it is prone to structural deformation, and the processing pass rate is low. How to effectively improve the production qualification rate of the front plate base and ensure its processing quality is an...
