Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a two-sided folding and pressing machine. Background Technology

[0002] Folding and pressing machines are key pieces of equipment in industries such as furniture manufacturing and automotive interiors, used for edge-binding of products. They are mainly used to fold and press leather, fabric, and other covering materials to fix them to the product edges. Traditional edge-binding processes usually require manual pre-folding followed by pressure-holding and fixing using pressure equipment.

[0003] The existing edge folding and pressure holding machine relies on manual operation. From pre-folding to pressure holding and fixing, the entire process must be done manually. Manual edge folding is prone to problems such as inconsistent edge width and uneven edge angle, resulting in unstable processing quality and low production efficiency. At the same time, workers need to perform repetitive manual work continuously, which is labor-intensive. Therefore, a double-sided edge folding and pressure holding machine is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a two-sided folding and pressing machine, which has the advantages of high production efficiency and stable processing quality without the need for manual operation, thus solving the problems of low processing efficiency and unstable quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a two-sided folding and pressing machine, comprising an upper mold device, a lower mold device, and a frame. The frame includes a base, a body, a top plate, and a top cylinder. The body is located on top of the base, and the top plate is disposed on top of the body. The top cylinder is disposed on top of the top plate, and its bottom output end passes through the bottom of the top plate and is connected to the upper mold device. A fixing plate is fixedly disposed on the top of the base, and a product processing part is disposed at the middle position of the top of the fixing plate. The lower mold device and the upper mold device process the product processing part through a processing structure.

[0006] Furthermore, the body is a rectangular frame formed by three metal plates, and each of the three metal plates of the body has a motor body clearance hole, and the base has handles on both sides.

[0007] Furthermore, the upper mold device includes an upper fixed plate and two pre-folding plates A on both sides. The upper fixed plate is fixedly connected to the output end of the top cylinder, and the two pre-folding plates A on both sides are respectively arranged at the left and right ends of the upper fixed plate.

[0008] Furthermore, the bottom of the two pre-folded plates A on both sides is in the shape of an arc-shaped groove, which can precisely embed the arc edges on both sides of the product part into the arc-shaped groove for positioning.

[0009] Furthermore, the lower mold device includes two pre-folding plate B cylinders on both sides, two pre-folding plates B on both sides, two edge-folding cylinders, and two edge-folding devices. The two pre-folding plate B cylinders on both sides are respectively arranged in front of and behind the fixed plate to clamp the product processing part in the middle. The two pre-folding plates B on both sides are respectively arranged at the output ends of the two pre-folding plate B cylinders on both sides. The two edge-folding cylinders are respectively arranged on the left and right sides of the fixed plate. The two edge-folding devices are respectively arranged on the output ends of the two edge-folding cylinders.

[0010] Furthermore, the tail ends of the two folding cylinders and the tail end of one of the two pre-folding plate B cylinders pass through the three motor body clearance holes on the machine body. The top of the fixing plate is provided with a folding base for supporting the product processing part. The top two sides of the folding base are also provided with arc-shaped slots that match the arc-shaped edges on both sides of the product processing part to facilitate the stability of the product processing part.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. This double-sided folding and pressing machine uses a top cylinder to press down the two pre-folding plates A on both sides of the upper mold device to limit the top of the product part. At the same time, the folding cylinder of the lower mold device and the cylinders of the two pre-folding plates B limit the front, back, left and right sides of the product part, thereby achieving the effect of unstable processing quality and high production efficiency.

[0013] 2. This double-sided folding and pressing machine shortens the processing time of a single piece through automated processing. At the same time, it ensures the safety of operators and reduces the labor intensity of personnel by controlling the start switch and photoelectric protection device. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 In this embodiment, a two-sided folding and pressing machine has a frame 300 consisting of a base 301, a body 302, and a top plate 303. The base is a rectangular steel plate with handles 305 welded on both sides for easy handling. The body is a rectangular frame enclosed by three metal plates, each with a motor clearance hole for the cylinder tail to pass through. The top plate is fixed to the top of the body for mounting the top cylinder 304.

[0020] The upper mold device 100 includes an upper fixed plate 101 and two pre-folding plates A102 on both sides. The upper fixed plate is bolted to the output end of the top cylinder. The two pre-folding plates A are symmetrically fixed to the left and right ends of the upper fixed plate. The bottom of the pre-folding plate A is an arc-shaped groove that matches the arc-shaped edge of the product processing part 500 to ensure precise positioning when pressing down.

[0021] The lower mold device 200 includes two sets of symmetrical structures:

[0022] • Pre-folding section: The pre-folding plates B on both sides are driven by cylinder 201 to clamp the product from the front and back directions;

[0023] • Folding section: The folding cylinder 203 pushes the folding device 204 to complete the folding from both sides. The folding device has a built-in heating element and temperature sensing wire, which heats up to the set temperature during pressure holding. The top of the folding base 205 has an arc-shaped groove to fit the edge of the product for stable positioning.

[0024] Fixed plate 400 and product processing parts 500

[0025] The fixing plate 400 is fixed to the top of the base with bolts, and the product part 500 is placed in its central area. The arc-shaped groove of the folded base further ensures that the product part does not shift during processing.

[0026] The working principle of the above embodiments is as follows:

[0027] First, place the product part 500 into the folding base 205, ensuring that its two side edges are aligned with the arc-shaped groove. Press the switch with both hands, and the top cylinder 304 drives the upper mold device 100 to press down. The pre-folding plate A102 presses the product and pre-folds the edge. The pre-folding plate B cylinder 201 pushes the pre-folding plate B202 to pre-fold the product part 500 a second time from the front and back direction. The folding cylinder 203 starts, and the folding device 204 folds the product part 500 completely into the edge of the product. At the same time, the heating tube heats and maintains pressure. Each cylinder resets in sequence, the finished product is taken out, and the next cycle begins. Through the above process, efficient and stable integrated folding and pressure-maintaining operation is achieved, which significantly improves production efficiency and product quality.
