Description

Technical Field

[0001] This utility model belongs to the field of furniture hardware processing technology, and in particular relates to a punch press for processing furniture hardware. Background Technology

[0002] In the furniture manufacturing industry chain, hardware plays a crucial role. Hinges, drawer slides, handles, connectors, locks, and support components—these seemingly small metal parts are key to determining the smoothness of furniture opening and closing, load-bearing capacity, lifespan, and overall quality. Punch presses (also known as stamping machines) are the core production equipment for mass production, high efficiency, and high precision manufacturing of these hardware products. Punch presses utilize powerful mechanical force (or hydraulic or servo power) to drive dies to instantly complete various plastic deformation processes on metal sheets (mainly cold-rolled steel, stainless steel, and aluminum alloys), including punching (separation), bending, stretching, flanging, and stamping. Their punching speed (number of punches per minute) is far higher than other processing methods (such as milling and turning), making them ideal for the large-scale production needs of furniture hardware.

[0003] In existing technologies, furniture hardware products (especially slender strips) lack effective fixation during stamping, causing the workpiece to shift or deviate under impact force, affecting punching accuracy and product quality. Furthermore, traditional punch presses lack guiding structures when moving the workpiece to the stamping position, making it prone to sliding or shifting and difficult to accurately align with the underside of the punch, resulting in punching position deviations. Therefore, we provide a furniture hardware product processing punch press to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a punching machine for processing furniture hardware products. It uses two sets of abutment plates to position the product, thereby ensuring the stability of the product during the punching process and preventing the product from shaking or deviating. At the same time, through the cooperation of the stroke bar and the product, it ensures the stability of the product's movement, so that the product moves stably to the underside of the telescopic punch rod, and ensures the accuracy of the subsequent punching process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a punch press for processing furniture hardware products, including a punch press body; a processing table is provided at the processing position of the punch press body, a lifting frame is provided directly above the processing table, a telescopic punch rod is bolted to the side wall of the punch press body directly above the lifting frame, a telescopic cylinder is fixed in a recess on the side wall of the punch press body, and movable openings communicating with the inside of the lifting frame are provided on the lower end face of the lifting frame on both sides of the telescopic punch rod, and abutment plates are slidably provided inside the movable openings.

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 7This utility model is a punching press for processing furniture hardware products. It uses two sets of abutment plates 4 to position the product, thereby ensuring the stability of the product during the punching process 203 and preventing the product from shaking or deviating. At the same time, through the cooperation of the stroke bar 302 with the product, it ensures the stability of the product's movement, so that the product moves stably to the underside of the telescopic punch 101, and ensures the accuracy of the subsequent punching process 203.

[0028] Specifically, the punch press body 1 has a processing table 3 at its processing position. A lifting frame 2 is positioned directly above the processing table 3. A telescopic punch rod 101 is bolted to the side wall of the punch press body 1 directly above the lifting frame 2. A telescopic cylinder 102 is fixed in a recess on the side wall of the punch press body 1. Movable openings 204, communicating with the interior of the lifting frame 2, are opened on the lower end faces of the lifting frames 2 on both sides of the telescopic punch rod 101. Abutment plates 4 are slidably installed inside each movable opening 204. A positioning block 301 is fixed to the upper end face of the processing table 3. A travel bar 302 is bolted to the side wall of the positioning block 301. Two sets of L-shaped bars 303, which are flush with the two sides of the travel bar 302, are fixed on the upper end face of the travel bar 302. An assembly plate 202, which is bolted to the piston end of the telescopic cylinder 102, is fixed on the side wall of the lifting frame 2. The assembly plate 202 is slidably set in the recess of the punch press body 1. A drop hole 304, which penetrates the lower end face of the processing table 3, is opened on the upper end face of the positioning block 301. A punch hole 203, which is aligned with the upper and lower positions of the drop hole 304, is opened on the lower end face of the lifting frame 2. The lower end of the telescopic punch rod 101 passes through the punch hole 203. The lower end face of the telescopic punch rod 101 is bolted to the bottom surface inside the lifting frame 2.

[0029] The operation process of this embodiment is as follows: When punching 203 on furniture hardware products using the above structure, the straight hardware product is placed at the upper end of the travel bar 302, and the product is moved from the upper end of the travel bar 302 to the position below the telescopic punch rod 101. At this time, the cylinder on the punch press body 1 is controlled to work. The cylinder will drive the telescopic punch rod 101 to move downward through the assembly plate 202 and the lifting frame 2, so that the telescopic punch rod 101 moves out from the punching 203 position, thereby punching 203 on the product. After the lifting frame 2 moves downward, it will drive the abutment plate 4 to contact the upper end surface of the product. The abutment plate 4 abuts and positions the product, thereby ensuring the stability of the product during the punching 203 process and avoiding shaking or deviation of the product.

[0030] Example 2

[0031] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6Based on Example 1, the pushing force of the abutment plate 4 on the hardware product is increased by the combined use of the strip block 404 and the spring 403.

[0032] Specifically, a strip block 404 is fixed on the upper end face of the abutment plate 4, which slides inside the lifting frame 2. Limiting holes 405 are opened through both ends of the strip block 404. Limiting rods 401 are slidably installed inside the limiting holes 405. Locking plates 402 that are bolted to the inner wall of the lifting frame 2 are fixed at both ends of the limiting rods 401. A calibration plate 201 that is connected to the inner wall of the punch press body 1 is fixed on the upper end face of the lifting frame 2. Springs 403 are sleeved on the limiting rods 401 located above the strip block 404. The plates fixed at both ends of the springs 403 are connected to the locking plates 402 and the end faces of the strip block 404 by bolts.

[0033] The operation process of this embodiment is as follows: When the abutting plate 4 abuts against the hardware product, the abutting plate 4 will slide along the inside of the movable opening 204. Then, the strip block 404 on the upper surface of the abutting plate 4 will slide along the limiting rod 401 through the limiting hole 405. Thus, the limiting block compresses the spring 403, and the spring 403 pushes the limiting block, thereby increasing the pushing force of the abutting plate 4 on the hardware product. When the lifting frame 2 moves, it will drive the calibration plate 201 to slide along the inner wall of the punch press body 1, thereby ensuring the stable movement of the lifting frame 2.
