It is widely used in stamping and forming in the fields of electronics, communications, computers, home appliances, furniture, transportation, hardware parts, etc.

[0003] When the existing punching machine is processing, Figure 1 and Figure 2 As shown, the product is punched by a side-pushing slider 3 through a punching upper die 1, a punching lower die 2, a slider 3 and a die blade 4. The longitudinal force is converted into a lateral force through the slider. This processing method has the following disadvantages:

[0004] (1) If the product being processed is a pipe fitting, the positioning is not accurate enough, and abnormal conditions such as inadequate loading often occur;

[0005] (2) The mold blade becomes non-vertical force, and the mold parts are more damaged;

[0006] (3) When processing the product, it is necessary to hold the product by hand for positioning, which poses certain safety risks. Utility Model Content

[0007] The purpose of the utility model is to provide a cylinder side punching special machine in order to solve the above problems.

[0009] Preferably, the punch guide block is in the shape of an arc-shaped end surface whose lower end matches the contour of a pipe-like product.

[0010] Preferably, a channel connected to the core rod blade loading structure is opened in the middle of the punch guide block, and the cylinder is provided with a telescopic rod that can be telescopically driven to pass through the channel to push against products such as pipes.

[0011] Preferably, pressure blocks capable of positioning the side punch sliders are provided on both sides of the seat plate, and the knife edge mandrel seat is clamped between the pressure blocks on both sides.

[0012] Preferably, the core rod blade loading structure of the blade core rod seat is equipped with different sizes and specifications and can be disassembled and replaced.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The hollow structure of the core rod blade loading structure is used to place pipe fittings, and the punch guide block is used for sliding positioning, which effectively avoids abnormal working conditions where the loading is not positioned in place; the punching processing method is vertical force, which effectively improves the life of wearing parts; after loading and positioning, there is no need to manually support the workpiece, which effectively improves the safety factor of equipment processing.

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] A cylinder side punch special machine, such as Figure 3 and Figure 4 As shown, it includes a seat plate 5, a side punch slider 7 driven by a cylinder 6, and a blade mandrel seat 9. The blade mandrel seat 9 is provided with a core rod blade loading structure with a hollow structure. The core rod blade loading structure is used to place pipe fittings through the hollow structure. The blade mandrel seat 9 is provided with punch guide blocks 8 on both sides of the core rod blade loading structure for slidably positioning pipe fittings.

[0022] The shape of the punch guide block 8 is an arc-shaped end face whose lower end matches the contour of the pipe fittings. When the pipe fittings are loaded, the end of the pipe fittings away from the punching process is aligned and inserted into the hollow structure of the core rod blade loading structure of the blade core rod seat 9, and the end close to the punching process is placed on the upper end of the arc-shaped end face of the punch guide block 8, and the depth of the insertion of the pipe fittings into the hollow structure position can be adjusted according to the punching blade processing position;

[0023] A channel 10 connected to the core rod blade loading structure is provided in the middle of the punch guide block 8, and the cylinder 6 is provided with a telescopic rod that can be telescopically driven to pass through the channel 10 and press against the pipe fittings. When the pipe fittings are inserted into the hollow structure of the core rod blade loading structure and the blade processing position is adjusted, the cylinder 6 drives the telescopic rods on both sides and the side punch slider 7 to approach the pipe fittings. The telescopic rods are positioned against the pipe fittings through the channel 10, and at the same time, the punch guide block 8 is pressed to slide and clamp the pipe fittings.

[0024] Pressure blocks 11 for positioning the side punch slider 7 are provided on both sides of the seat plate 5. The pressure blocks 11 can position and block the side punch slider 7 to prevent it from loosening and displacement, and the blade mandrel seat 9 is clamped between the pressure blocks 11 on both sides, which can ensure the accuracy of the punching processing position; the core rod blade loading structure of the blade mandrel seat 9 is equipped with different sizes and specifications and can be disassembled and replaced. When it is necessary to punch and process pipe fittings of different diameters, the corresponding core rod blade loading structure can be replaced and matched to improve the versatility of the equipment.
