Description
Technical Field
[0001] The utility model relates to the technical field of bending die processing, in particular to a punching die device with positioning and anti-deviating functions. Background Art
[0002] Bending die processing refers to the manufacture of tools used to bend metal sheets or tubes into specific shapes. These dies are usually made of carbide steel or other wear-resistant materials to ensure that they maintain their shape and accuracy during long-term use. The role of the die device is to provide necessary pre-processing for bending, such as creating the curve shape required for bending on the metal sheet or punching holes in the tube to ensure the accuracy of the bending. By reasonably designing the process flow and matching relationship between the die and the bending die, efficient processing and forming of metal materials can be achieved.
[0003] A die device is a device used to punch, shear, form or process metal or other materials. It usually consists of an upper die and a lower die. The upper die is fixed on the upper part of the punch press, and the lower die is fixed on the lower part of the punch press. The die device uses impact force to move the upper and lower dies relative to each other, thereby punching, shearing or forming the material. The die device can be used to manufacture various metal products, such as automotive parts, household appliances, industrial equipment parts, etc.
[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 4 , the utility model provides a technical solution: a die device with positioning and anti-deviating function, comprising a fixing rod 1, a bottom plate 2 is inserted under the fixing rod 1;
[0023] A support plate 101 is inserted above the fixing rod 1, a first cylinder 102 is inserted above the supporting plate 101, a fixing groove 105 is installed below the supporting plate 101 by screws, a first spring 106 is attached inside the fixing groove 105, a pressing block 104 is attached below the first spring 106, and a limiting plate 103 is attached to one side of the fixing groove 105;
[0024] A fixing plate 204 is welded on the top of the base plate 2, and a second cylinder 203 is installed on the top of the fixing plate 204 by screws. An extrusion block 202 is inserted into the output shaft on one side of the second cylinder 203, and a second spring 205 is inserted into one side of the extrusion block 202. A slide groove 201 is welded on one side of the fixing plate 204, and a limiting groove 208 is attached to one side of the extrusion block 202. A push plate 207 is attached to the inside of the limiting groove 208, and a third cylinder 206 is inserted below the push plate 207.
[0025] In this embodiment, Figure 3As shown, the pressing block 104 forms an elastic structure through the first spring 106; the lack of positioning and anti-deviating function may cause collision or incorrect impact between the mold and the workpiece, thereby increasing the risk of wear and damage to the equipment. In the long run, the cost of repairing and replacing the mold will increase. The bending mold is fixed by the pressing block 104, and the pressing block 104 is connected to the first spring 106. The pressing block 104 moves in the fixing groove 105. The pressing and fixing by the first spring 106 can provide greater pressure, ensuring that the workpiece or the die remains in a stable position during the processing process to prevent displacement or loosening due to vibration or external force.
[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the internal structure size of the support plate 101 is consistent with the external structure size of the fixed rod 1, and the support plate 101 forms a sliding structure through the first cylinder 102; the mechanical structure of the die device is usually composed of a base, a frame, a slider, a cylinder, an oil pump, a hydraulic pipeline, a hydraulic valve and other components. Generally, the force of the cylinder pressing and fixing is limited by the pressure and size of the cylinder, and cannot provide a large force compared with hydraulic or mechanical fixation. Therefore, it may not be stable enough in some cases where high-pressure fixation is required. The cylinder pressing and fixing has poor stability when subjected to vibration or external force impact, and is prone to loosening or displacement, affecting the processing accuracy and product quality. Now the improvement is that the first cylinder 102 is used to vertically move the support plate 101 on the fixed rod 1 downward, so that the support plate 101 is convenient for the overall downward movement of the support plate 101. The support plate 101 is fixed with the pressing block 104. The first cylinder 102 provides stable pressure, and the first spring 106 inside the pressing block 104 can absorb impact under pressure changes or external forces, thereby increasing the stability of the fixation and ensuring that the workpiece maintains a stable position during the processing.
[0027] In this embodiment, Figure 4 As shown, the extrusion block 202 forms an elastic structure through the second spring 205, and the extrusion block 202 forms a sliding structure through the second cylinder 203; the lack of a buffer device may lead to problems such as excessive impact force, reduced processing accuracy, increased risk of equipment damage, increased noise and vibration, and increased safety hazards, affecting the stability, safety and processing quality of the equipment. Now the second cylinder 203 is improved to make the extrusion block 202 move in parallel, and the extrusion block 202 passes through the second spring 205. The second spring 205 can absorb part of the impact energy during the movement of the extrusion block 202, slowing down the movement speed of the extrusion block 202 by the second cylinder 203, thereby effectively reducing the impact force, reducing the impact on the equipment and the mold, and extending the service life of the equipment and the mold.
[0028] In this embodiment, Figure 4As shown, the internal structural dimensions of the limit groove 208 are consistent with the external structural dimensions of the push plate 207, and the push plate 207 forms a sliding structure through the third cylinder 206; the residues accumulated inside the die device may become a safety hazard, for example, it may cause injuries to workers during cleaning or maintenance, or cause abnormal conditions during equipment operation, increasing the risk of accidents. The third cylinder 206 enables the push plate 207 to move vertically upward, which is convenient for cleaning waste chips from the die limit plate 103 and for taking away workpieces.
[0029] In this embodiment, Figure 3 and Figure 4 As shown, the external structural dimensions of the lower oblique section of the limit plate 103 are consistent with the external structural dimensions of the upper oblique section of the extrusion block 202; the pressing block 104 moves downward, and the limit plate 103 can also fix the extrusion block 202 to prevent the second spring 205 from rebounding to its original position due to inertia, thereby achieving the effect of the limit plate 103 limiting the pressing block 104.
[0030] The use method and advantages of the utility model: When the punching die device with positioning and anti-deviating function is used, the working process is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the mold is placed inside the limiting groove 208, and the first cylinder 102 vertically drives the support plate 101, the fixing groove 105 and the pressing block 104 to move downward in sequence, so that the pressing block 104 elastically fixes the mold through the first spring 106, and the second cylinder 203 moves the extrusion block 202, and the chamfered surface of the extrusion block 202 is fitted and fixed with the chamfered surface of the limiting plate 103, so that the arc processing of one side of the pressing block 104 is realized, and the second spring 205 reduces the impact force. After processing, the extrusion block 202 and the pressing block 104 return to the initial position, and the third cylinder 206 vertically drives the workpiece on the push plate 207 to move out, so as to realize the function of rapid demolding and convenient cleaning of the workpiece.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
