The stamping apparatus of this embodiment is used to produce ceramic dielectric filters, which have high requirements for the production apparatus, in particular with regard to structural stability. In the punching apparatus of the present embodiment, the punching assembly 1 includes the mandrel assembly 10, and the mandrel 11 and the base 12 in the mandrel assembly 10 are fixed by welding, so that the stability of the relative position between the mandrel 11 and the base 12 is high. Therefore, when the stamping assembly 1 bears a large force, the mandrel 11 cannot be easily loosened, the position deviation of the mandrel 11 is small, and the yield of the processed workpiece is high. When the punching assembly 1 punches a workpiece, the punching assembly 1 indirectly provides pressure to the mandrel assembly 10 through the backing plate 20, and then the mandrel 11 punches to a preset position of the workpiece to machine a required hole-shaped structure on the workpiece. The caul plate 20 can protect the mandrel assembly 10 and reduce damage to the mandrel assembly 10 from direct forces or direct rigid contact.

When a workpiece is machined, the stamping assembly 1 in the stamping equipment is stressed to stamp the workpiece along the axis of the core rod 11, so that structures such as a round blind hole are machined on the workpiece. The backing plate 20 is stressed and transmits the pressure to the base 12, the base 12 is stressed to enable the core rod 11 to punch the workpiece at a sufficient pressure and speed, the punching assembly 1 stops after reaching a preset position, and a hole-shaped structure with a preset shape and a preset depth is machined. The core rod 11 and the base 12 are fixed through welding, the stable fixing structure enables the core rod 11 not to move when stressed, and in the pressing and demolding process, the probability of cracks at the bottom of an inner hole of a product is reduced, and the yield is improved.

Optionally, in the stamping apparatus in this embodiment, the stamping assembly 1 may include only one mandrel 11, or may include a plurality of mandrels 11; the mounting portion 121 may be a protruding boss, the mandrel 11 may be fixed to the boss, the mandrel 11 may be a recess in the base 12, the mandrel 11 may be fixed in the recess, and the mounting portion 121 may have another structure. The number of mandrels 11 and the specific configuration of the mounting portion 121 may be selected as desired. Alternatively, the punch assembly 1 may be fixed by the base 12.

Fig. 3 is a schematic structural view of a second embodiment of the press apparatus of the present application.

As shown in fig. 3, in the press apparatus, one end of the mandrel 11 is embedded in the mounting portion 121 and fixed to the base 12, and the other end of the mandrel 11 is used to press a predetermined shape on the workpiece.

One end of the mandrel 11 is embedded in the mounting portion 121, so that the base 12 stably fixes the mandrel 11. The other end of the core rod 11 may be used to machine a hole-like structure into a workpiece. When the workpiece is punched, the base 12 of the mandrel assembly 10 is stressed, so that the mandrel assembly collides with the workpiece at a certain speed and force and stops after reaching a preset position. If the structural and positional relationship between the mandrel 11 and the base 12 is not stable enough, the mandrel 11 may move when contacting the workpiece.

In some embodiments of the present embodiment, the mandrel 11 is welded to the surface of the base 12 or a boss protruding from the surface of the base 12. At this time, the perpendicularity of the core rod 11 is difficult to ensure, and the welding process requirement is high. In the present embodiment, one end of the core rod 11 is embedded in the mounting portion 121 and fixed to the base 12, and the two are engaged with each other by the post and the hole, so that the position relationship between the two is stable, and the verticality of the core rod 11 is more easily ensured. Therefore, when the mandrel 11 contacts the workpiece at a certain speed and force, the mandrel 11 can be stably stamped to the preset position without moving or shaking, and the preset shape and structure can be stably punched at one time.

Optionally, the mandrel assembly 10 comprises a plurality of mandrels 11, the plurality of mandrels 11 are arranged at intervals, and the axis of each mandrel 11 is arranged perpendicular to the base 12.

The base 12 provides a punching force to the core rod 11. When the base 12 provides a pressure to the mandrel 11 parallel to the mandrel 11 and perpendicular to the base 12, the mandrel 11 has a better verticality. The forces to which it is subjected do not cause the mandrel 11 to buckle when it contacts the workpiece. When the core rod 11 is not perpendicular to the base 12, a component is generated in a direction perpendicular to the axis of the core rod 11 by the pressure applied to the core rod 11, so that a moment for bending the core rod 11 is generated, and the conventional core rod 11 is subjected to bending deformation and needs to be maintained or replaced for continuous use, thereby increasing the cost. This embodiment enables the mandrel 11 to be perpendicular to the base 12, which reduces the risk of bending deformation of the mandrel 11. The mandrel assembly 10 is provided with a plurality of mandrels 11 so that the plurality of mandrels 11 can be simultaneously moved to perform the punching. For a workpiece needing to be processed with a plurality of hole-shaped structures, a plurality of core rods 11 are punched simultaneously and are punched one by one relative to a single core rod 11, so that the efficiency is greatly improved.

The perpendicularity of the mandrel 11 is also an important factor in determining the quality of the machined workpiece when the workpiece is stamped by the mandrel 11. Stamping the mandrel 11 perpendicular to the workpiece is better able to stamp the workpiece with fewer shape and configuration defects. The plurality of core rods 11 act on the workpiece at the same time, a plurality of hole-shaped structures can be machined on the workpiece at one time, time is saved, and efficiency is improved. A plurality of mandrels 11 arranged at intervals are all fixed with the base 12. Therefore, the structure of the mandrel component 10 is more stable, the mandrel 11 does not move when punching is carried out, the probability of cracks at the bottom of an inner hole of a workpiece is reduced, and high yield can be ensured while the efficiency is improved.

Alternatively, the mounting portion 121 includes a mounting groove, a side wall of which is provided with a screw thread, and one end of each core rod 11 is embedded in the mounting groove and engaged with the screw thread. The mandrel 11 is arranged in the mounting groove, and the mandrel 11 is in threaded fit with the mounting groove. The fixing mode enables the core rod 11 to be detachably fixed on the base 12, and the core rod 11 is convenient to replace. When the rigidity of the mandrel 11 and the base 12 meets the requirement, after the mandrel 11 is assembled on the base 12 through threads, the positional relationship between the mandrel 11 and the base 12 is accurate enough, and a qualified workpiece can be processed.

Alternatively, the mounting portion 121 includes a mounting groove, and the mandrel 11 is embedded in the mounting groove and fixed by welding. In the present embodiment, the mandrel bar 11 is embedded in the mounting groove and fixed by welding, and at this time, the mandrel bar 11 is fixed to the base 12 accurately and stably. Since the stamping assembly 1 needs to bear a large force frequently, the stable fixation between the core rod 11 and the base 12 can ensure a high yield. The mandrel 11 and the base 12 are welded together, so that when the punching assembly 1 punches a workpiece, the mandrel 11 cannot move, and the position of the mandrel 11 cannot shift. Therefore, cracks cannot be generated at the bottom of the inner hole of the workpiece due to the movement of the core rod 11 in the pressing and demoulding process, and the yield is greatly improved.

Optionally, the backing plate 20 is disposed on a side of the base 12 away from the mandrel 11, and the backing plate 20 covers a side of the base 12 away from the mandrel 11.

The base plate 20 covers the side of the base 12 far from the core rod 11, so that the base 12 can be uniformly stressed, and the core rod 11 can also punch the workpiece under the same force. The caul plate 20 protects the mandrel assembly 10 by reducing localized pressure through surface contact, protecting the mandrel assembly 10, and particularly the base 12, from damage. When the plurality of core rods 11 act on the workpiece with the same force, the workpiece is not chipped or damaged due to imbalance of the force. Alternatively, the backing plate 20 may be a rigid material, in rigid contact with the base 12; the caul plate 20 may also be a flexible material to provide greater protection to the mandrel assembly 10.

Optionally, the mounting portion 121 includes a mounting hole, the core rod 11 is disposed through the mounting hole, and one end of the core rod 11 disposed through the mounting hole abuts against the backing plate 20. The core rod 11 is inserted into the mounting hole and abuts against the backing plate 20, so that the core rod 11 can be supported by the backing plate 20 at the same time. The core rod 11 penetrates through the mounting hole, so that the core rod 11 has good verticality, and the processed workpiece has high yield. During punching, the base 12 is fixed with the mandrel 11, and the mandrel 11 is supported by the backing plate 20, so that the mandrel 11 is simultaneously provided with a force parallel to the axis of the mandrel 11 by the base 12 and the backing plate 20, and meanwhile, the position of the mandrel 11 on the axis perpendicular to the axis of the mandrel 11 is limited by the mounting hole, the mandrel 11 is prevented from deviating from the axis, and the better processing effect is achieved.

Optionally, the base 12 is provided with a counterbore 122, and a fastener passes through the counterbore 122 to secure the base 12 and the backing plate 20. Fixed through the mounting between base 12 and the backing plate 20, the multiple punching press also is difficult to make base 12 and backing plate 20 dislocation, has improved the structural stability of punching press subassembly 1, is favorable to improving the yields.

Optionally, the punching assembly 1 includes a limiting plate 30, the limiting plate 30 is provided with a limiting hole 31, the mandrel 11 is inserted into the limiting hole 31, and the limiting plate 30 is used for limiting the position of the mandrel 11. The mandrel 11 is fixed with the base 12 through welding, and meanwhile, the perpendicularity of the mandrel 11 can be well guaranteed by sleeving a limiting plate 30 on the mandrel 11. Even if an error exists in the process of fixing the mandrel 11 due to welding flaws, the error can be corrected through the limiting plate 30, and the perpendicularity of the mandrel 11 is guaranteed.
