Description

Technical Field

[0001] The invention relates to a production process for an integrally formed seat base fixing bracket, belonging to the technical field of agricultural machinery production. Background Art

[0002] In modern manufacturing, with the increasing demand for product diversification and personalization, traditional production processes are facing increasing challenges. Especially in the production of components for high-end commercial lawn mower seat systems, manufacturing cost control is particularly important. As a core component, the seat support plate has a low production demand, but the product precision and quality requirements are very strict. Therefore, finding an efficient and economical manufacturing process has become the key.

[0003] Although the traditional stamping process can achieve large-scale production, for parts with large shapes and high material strength, high-tonnage stamping machines (such as 1,000-ton stamping machines) and corresponding high-cost molds are often required. This not only increases equipment investment, but also increases production cycle and production costs, causing enterprises to be at a disadvantage in the fierce market competition. In addition, the mold manufacturing cycle is long, and the maintenance and replacement costs are high, which greatly reduces the flexibility of small-batch production.

[0004] In order to solve the above problems, laser blanking technology came into being. As an emerging manufacturing process, laser blanking has the advantages of high precision, high flexibility and low production cost. Compared with the traditional stamping process, laser blanking does not require expensive molds and can be cut directly from CAD data, which greatly shortens the production cycle and adapts to the production needs of small batches and multiple varieties. At the same time, laser cutting can realize the processing of complex shapes and improve the design freedom of parts.

[0005] Taking into account the characteristics of the seat support plate, the laser cutting and step-by-step forming process is adopted, which can not only effectively control the manufacturing cost, but also improve the production efficiency while ensuring the quality of the parts. Summary of the invention

[0006] In view of the problems existing in the above-mentioned prior art, the present invention provides a production process for an integrally formed seat base fixing bracket, thereby solving the above-mentioned technical problems.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an integrally formed seat base fixing bracket, including an intermediate main bracket; the upper part of the intermediate main bracket is connected to the seat cushion; the bottom of the intermediate main bracket is connected to the vibration damping bracket; a rear end backrest is provided on one side of the intermediate main bracket; the rear end backrest is connected to the backrest; the front end of the intermediate main bracket is connected to a front baffle; the front baffle is arranged tilted forward.

[0008] Furthermore, the base fixing bracket is made of low-alloy impact-resistant steel Q355D as a whole, and its overall thickness is 4.5 mm.

[0009] Furthermore, the base fixing bracket is integrally provided with a plurality of reinforcing ribs for improving the overall strength of the workpiece.

[0010] A production process for an integrally formed seat base fixing bracket comprises the following steps: Step 1: Laser cutting: Place the prepared material on the laser cutting machine and cut the material using a computer-controlled laser beam; Step 2: The first molding technology, the cut parts are placed on the molding machine for the first molding; Step 3: After the initial forming, the punching process is carried out. In this step, a special punching device is used to punch the required holes on the parts to meet the needs of subsequent assembly and connection; Step 4: After punching, a second forming operation is performed to further adjust the shape of the part to achieve the required accuracy and appearance; Step 5: After the second molding, the final molding process is carried out to ensure that the parts finally meet the designed shape and strength requirements; Step 6: After completing all molding and processing steps, the finished product is inspected to ensure that it meets the design requirements and quality standards.

[0011] Furthermore, in step 1, the laser power is 800-2000 W, the cutting speed is 1-5 m / min, the focal length is controlled at 10-20 mm, and the gas pressure is 0.5-1.5 MPa.

[0012] Furthermore, the molding machine adopts a hydraulic or mechanical molding machine, the molding pressure is 50-200 tons, and the molding speed is 20-60 mm / s.

[0013] The beneficial effects of the present invention are: compared with the traditional stamping process, laser cutting does not require expensive molds, can be cut directly from CAD data, greatly shortens the production cycle, and adapts to the production needs of small batches and multiple varieties. At the same time, laser cutting can realize the processing of complex shapes and improve the design freedom of parts.

[0014] Considering the characteristics of the seat support plate, the laser blanking and lane forming process can not only effectively control the manufacturing cost, but also improve the production efficiency while ensuring the quality of the parts. The application of this technology will provide a forward-looking solution for the manufacturing of high-end commercial lawn mower seat systems, meeting the market demand for high-quality and low-cost products.
