Description

Technical Field

[0001] This invention belongs to the technical field of punch press equipment, specifically, it relates to a punch press for producing furniture hinges. Background Technology

[0002] Because of their complex structure and irregular shape, hinges are often manufactured by stamping, specifically using medium to large-sized stamping presses. In the production of stamped parts, steel, sheet metal, or steel plates are placed on a stamping die using stamping equipment. The stamping device above applies pressure to the steel through the stamping head, causing it to undergo plastic deformation or separation, thereby obtaining a hinge of the required shape and size.

[0003] In existing punching equipment, raw materials are typically placed manually into the processing slot. The stamping mechanism then uses a stamping block to press and shape the material into a finished product. The precision of the process affects the forming quality and production stability. Traditional punching production lines rely on manual labor or simple mechanisms to feed steel plates, lacking reliable limiting structures. This leads to misalignment and movement of the sheet metal during feeding and die positioning, resulting in dimensional errors, burrs, and increased scrap rates. When dealing with large-scale production, it's necessary to improve the equipment's processing efficiency. Manual operation becomes insufficient to meet these demands. Furthermore, when processing different hinge models, the material feeding position needs to be changed. Manual operation may introduce positional deviations, reducing production efficiency and ultimately lowering the precision of the finished product.

[0004] Therefore, it is necessary to improve upon the shortcomings and defects of the existing technology and provide a punch press for the production of furniture hinges. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a punch press for furniture hinge production that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a punch press for producing furniture hinges, comprising a punching press, wherein a lower positioning plate and an upper positioning plate are fixedly installed on the punching press, the lower positioning plate is uniformly provided with a plurality of lower positioning slide grooves, the upper positioning plate is uniformly provided with a plurality of upper positioning slide grooves, a lower punching die plate is slidably installed on the lower positioning plate, the bottom surface of the lower punching die plate is provided with a limiting slider that matches the lower positioning slide groove, an upper punching plate is slidably installed on the upper positioning plate, the upper punching plate is provided with a limiting slider that matches the upper positioning slide groove, the top surface of the lower punching die plate is provided with a punching die positioning groove, and a punching head is installed on the upper punching plate.

[0007] In order to position the rear ends of the lower stamping die plate and the upper stamping plate, preferably, a rear positioning slide rod is slidably installed on both the lower positioning plate and the upper positioning plate, and a limiting slider that matches the lower positioning slide groove and the upper positioning slide groove is fixedly installed on the rear positioning slide rod.

[0008] To control the sliding of the rear positioning slide rod, a first adjusting screw is rotatably installed on both sides of the lower positioning plate and the upper positioning plate, and the first adjusting screw is threadedly connected to the rear positioning slide rod.

[0009] To make the sliding of the rear positioning slide bar more precise, the lower positioning plate and the upper positioning plate are further provided with matching scale marks.

[0010] To further position the front ends of the lower stamping die plate and the upper stamping plate, a sliding block is slidably mounted on the rear positioning slide rod, a second adjusting screw is rotatably mounted on the sliding block, and a front positioning slider is rotatably mounted on the second adjusting screw.

[0011] To further stabilize the lower stamping die plate and the upper stamping plate, magnetic blocks are fixedly installed inside the lower positioning plate and the upper positioning plate, and metal blocks matching the magnetic blocks are fixedly installed inside the lower stamping die plate and the upper stamping plate.

[0012] In order to process different parts of the product to be processed, preferably, a sliding mounting plate is slidably mounted on the upper stamping plate, and the stamping head is fixedly mounted on the sliding mounting plate.

[0013] To control the sliding of the sliding mounting plate, four electric telescopic rods are further fixedly installed inside the upper stamping plate, and the driving end of the electric telescopic rods abuts against the side of the sliding mounting plate.

[0014] To facilitate the relative movement between the sliding mounting plate and the electric telescopic rod, a plurality of sliding balls are rotatably mounted on the side end of the sliding mounting plate, and the sliding balls are located at the connection between the electric telescopic rod and the sliding mounting plate.

[0015] To further improve the telescopic accuracy of the electric telescopic pole, multiple laser positioning sensors are fixedly installed on the upper stamping plate, and multiple laser positioning reflective stickers that match the laser positioning sensors are installed on the lower stamping die plate.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention is a punch press for producing furniture hinges. By replacing different models of lower punching die plates and punching heads, the punching die positioning groove on the lower punching die plate can be adapted to different models of products to be processed. The lower punching die plate and the upper positioning plate are limited and fixed by the positioning slide groove, so that the lower punching die plate and the upper positioning plate are matched and aligned. Then, the sliding mounting plate is slidably controlled by the electric telescopic rod, so that the punching head accurately processes the products to be processed in the punching die positioning groove, thereby improving production efficiency and finished product accuracy.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example

[0021] Reference Figure 1-6As shown, a punch press for manufacturing furniture hinges includes a punch press 1. A lower positioning plate 2 and an upper positioning plate 4 are fixedly installed on the punch press 1. The lower positioning plate 2 is evenly provided with a plurality of lower positioning grooves 201, and the upper positioning plate 4 is evenly provided with a plurality of upper positioning grooves 401. A lower punching die plate 3 is slidably installed on the lower positioning plate 2. The bottom surface of the lower punching die plate 3 is provided with a limiting slider that matches the lower positioning grooves 201. An upper punching plate 5 is slidably installed on the upper positioning plate 4. The upper punching plate 5 is provided with a limiting slider that matches the upper positioning grooves 401. The top surface of the lower punching die plate 3 is provided with a punching die positioning groove 301, and a punching head 6 is installed on the upper punching plate 5.

[0022] Both the lower positioning plate 2 and the upper positioning plate 4 are slidably mounted with rear positioning slide rods 7. The rear positioning slide rods 7 are fixedly mounted with limit sliders that match the lower positioning slide groove 201 and the upper positioning slide groove 401. By sliding the rear positioning slide rods 7, the rear ends of the lower stamping die plate 3 and the upper stamping plate 5 are positioned to prevent the lower stamping die plate 3 and the upper stamping plate 5 from sliding excessively backward.

[0023] Both sides of the lower positioning plate 2 and the upper positioning plate 4 are rotatably equipped with a first adjusting screw 701. The first adjusting screw 701 is threadedly connected to the rear positioning slide rod 7. By rotating the first adjusting screw 701, the sliding distance of the rear positioning slide rod 7 is adjusted, so that the sliding of the rear positioning slide rod 7 can be finely adjusted to allow the lower stamping die plate 3 and the upper stamping plate 5 to slide in a small and controllable manner, thereby aligning the lower stamping die plate 3 and the upper stamping plate 5 vertically.

[0024] The lower positioning plate 2 and the upper positioning plate 4 are provided with matching scale marks. The scale marks enable the upper and lower rear positioning slide rods 7 to match and align, thereby making the lower stamping die plate 3 and the upper stamping plate 5 match and align.

[0025] A sliding block is slidably mounted on the rear positioning slide rod 7, and a second adjusting screw 702 is rotatably mounted on the sliding block. A front positioning slider 703 is rotatably mounted on the second adjusting screw 702. By rotating the second adjusting screw 702, the front positioning slider 703 is aligned with the front end of the lower stamping die plate 3 or the upper stamping plate 5 and combined with the rear positioning slide rod 7 to clamp and fix the lower stamping die plate 3 or the upper stamping plate 5 from the front and rear ends respectively. Finally, the rotation of the first adjusting screw 701 allows the lower stamping die plate 3 and the upper stamping plate 5 to slide back and forth.

[0026] Magnetic blocks are fixedly installed inside the lower positioning plate 2 and the upper positioning plate 4. Metal blocks matching the magnetic blocks are fixedly installed inside the lower stamping die plate 3 and the upper stamping plate 5. The magnetic attraction force maintains the stability of the lower stamping die plate 3 and the upper stamping plate 5 on the lower positioning plate 2 and the upper positioning plate 4.

[0027] A sliding mounting plate 501 is slidably mounted on the upper stamping plate 5, and the stamping head 6 is fixedly mounted on the sliding mounting plate 501. By sliding the sliding mounting plate 501, the stamping head 6 can perform stamping processing on different parts of the product to be processed on the lower stamping die plate 3.

[0028] Four electric telescopic rods 503 are fixedly installed inside the upper stamping plate 5. The driving end of the electric telescopic rod 503 abuts against the side of the sliding mounting plate 501. By controlling the extension and retraction of the electric telescopic rods 503, the sliding position of the sliding mounting plate 501 on the upper stamping plate 5 is controlled, thereby controlling the position of the stamping head 6.

[0029] Multiple sliding balls 504 are rotatably mounted on the side end of the sliding mounting plate 501. The sliding balls 504 are located at the connection between the electric telescopic rod 503 and the sliding mounting plate 501. When the electric telescopic rod 503 controls the sliding mounting plate 501 to slide back and forth or left and right, it will rub against the sliding mounting plates 501 on the other two sides. The sliding balls 504 prevent wear caused by excessive friction and facilitate the electric telescopic rod 503 to control the sliding of the sliding mounting plate 501.

[0030] Multiple laser positioning sensors 502 are fixedly installed on the upper stamping plate 5, and multiple laser positioning reflective stickers 302 that match the laser positioning sensors 502 are installed on the lower stamping die plate 3. The laser is emitted by the sliding mounting plate 501 and then reflected by the laser positioning reflective stickers 302 to accurately position the lower stamping die plate 3 and the upper stamping plate 5, thereby controlling the extension and retraction of the electric telescopic rod 503, so that the stamping head 6 on the sliding mounting plate 501 can accurately process the product to be processed on the lower stamping die plate 3.

[0031] Select the corresponding lower stamping die plate 3 and upper stamping plate 5 according to the product to be processed. Install the lower stamping die plate 3 through the lower positioning slide groove 201 and the upper stamping plate 5 through the upper positioning slide groove 401, so that the positions of the lower stamping die plate 3 and the upper stamping plate 5 are aligned and matched. Rotate the first adjusting screw 701 to control the sliding of the rear positioning slide rod 7, so that the rear positioning slide rod 7 abuts against the lower stamping die plate 3 and the upper stamping plate 5. Then rotate the second adjusting screw 702 to align the front positioning slide block 703 with the front end of the lower stamping die plate 3 or the upper stamping plate 5. Then, by engraving... Slightly rotate the first adjusting screw 701 to control the lower stamping die plate 3 and the upper stamping plate 5 to the corresponding positions. Precise positioning is achieved through the laser positioning sensor 502 and the laser positioning reflector 302. The product to be processed is placed and fixed in the stamping die positioning groove 301 of the lower stamping die plate 3. The stamping press 1 is started, causing the upper positioning plate 4 to move down. The stamping head 6 works to process the product to be processed. The extension and retraction of the electric telescopic rod 503 is controlled so that the stamping head 6 processes different areas of the product to be processed, and finally the processed hinge is obtained.
