[0002] Currently, Chinese furniture companies are facing challenges such as rising labor costs, resource and environmental pressures, increasingly fierce market competition, increasingly personalized product demands, and rapidly evolving technological innovations.

[0003] Some existing fixtures for chair frame shaping use manual shaping. Before manual shaping, the chair frame seat tube is moved manually to meet the standard requirements (i.e., the seat tube is level with the benchmark). During shaping, only one side can be shaped before the other side is shaped, which consumes a lot of manpower.

[0004] The drawbacks of the above-mentioned plastic surgery methods are: 1) Manual plastic surgery requires certain physical strength and technical skills from the operators; 2) Manual plastic surgery takes a long time and has low output; 3) Manual plastic surgery requires a separate process and needs to be completed independently by one employee. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a technical solution for chair frame shaping equipment, so as to solve the problems of time-consuming, labor-intensive and low-output caused by existing manual shaping.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: The chair frame shaping equipment includes an integrally formed base frame, chair legs, and seat frame. The shaping equipment includes a machine base, a positioning mechanism, and a shaping mechanism. The positioning mechanism is disposed on the machine base and is used to position the rear frame tube of the base frame. The shaping mechanism includes two sets, which are spaced apart on the machine base. The shaping mechanism includes a pressure rod to compress the seat frame to generate deformation.

[0007] Furthermore, a horizontal mounting plate is provided on the machine base, and the two sets of shaping mechanisms are spaced apart on the horizontal mounting plate.

[0008] Furthermore, the shaping mechanism includes a rotary motor, the drive shaft of which is rotatably engaged with the mounting base of the horizontal mounting plate, and a U-shaped frame is provided at the end of the drive shaft. The pressure rod is located on the side of the U-shaped frame away from the drive shaft, and the rotary motor drives the pressure rod and the U-shaped frame to rotate with the drive shaft.

[0009] Furthermore, the pressure rod is an inverted L-shaped rod, and the seat frame is placed between the horizontal side rods of the two inverted L-shaped rods and abuts against the horizontal side rods on both sides respectively; the bottom of the vertical side rod of the inverted L-shaped rod is bent towards the other pressure rod to form a positioning groove, which corresponds to the U-shaped frame and is used for the snap-fit ​​positioning of the side frame tube of the bottom frame.

[0010] Furthermore, the positioning mechanism includes a mounting plate and a baffle plate disposed on the mounting plate. The mounting plate has an L-shaped cross-section and forms a mounting groove with the baffle plate for engaging the rear frame tube of the positioning base frame.

[0011] Furthermore, the mounting bracket plate is parallel to the horizontal mounting plate, and is placed on both sides of the upper surface of the machine platform, and is placed on the same center line.

[0012] Furthermore, two motor switches are provided on the upper surface of the machine platform, and the two motor switches are respectively placed on both sides of the mounting plate to control the two rotary motors.

[0013] Furthermore, a display control screen is also provided on the upper surface of the machine platform, and the display control screen is equipped with the main switch of the shaping equipment.

[0014] Compared with the prior art, the present invention has the following advantages: This utility model of shaping equipment transforms the shaping process from manual to machine, making the operation simpler and more standardized, requiring less skill from operators, and significantly increasing output, saving energy and reducing emissions, and lowering production costs. The shaping equipment can be moved next to the preceding process of chair frame processing and merged with the preceding process, allowing one person to operate it simultaneously.
