Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a punch holder. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products).

[0003] Stamping is used in many fields, including sheet metal processing and packaging. In the packaging industry, stamping is used to process sheet products, such as aluminum foil sheets used to seal bottle openings. There are many ways to produce such products. One method is to set several stamping heads and several stamping seats on two driving rollers. The raw material is delivered from the joint between the two driving rollers. The stamping heads and stamping seats work together to cut the raw material under the action of the driving rollers, thereby obtaining the product of the required shape.

[0004] During this process, the cutting slits on the stamping block gradually become dull with wear, making it impossible for the stamping block to cut the raw material and thus preventing the production of the required products. To solve the above problem, the existing technology usually replaces the entire stamping block. Although this method solves the above problem, the number of stamping blocks on the drive roller is large and the high frequency of punching increases the probability of stamping block damage, making the direct replacement of stamping blocks costly. Therefore, a structure is designed to solve the problem that existing stamping blocks need to be replaced as a whole after some of them are damaged, which leads to high costs.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a punch holder.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punch seat, including a support seat for detachable connection with a drive roller, one end face of the support seat is set as an arc surface with the same radius as the drive roller, a through groove is provided at the center position of the support seat in the thickness direction, and an installation groove is provided at the opening of the through groove on one side of the arc surface, and a detachable die block is embedded in the installation groove.

[0008] The present invention is further configured such that: both sides of the support base located on one side of the arc surface in the length direction are provided with locking grooves that communicate with the mounting grooves, and each locking groove can be detachably connected with a clamping block for clamping the die head block.

[0009] The present invention is further configured such that: the pressing block is cuboid and its thickness is less than the depth of the locking groove; a first countersunk hole is provided on the end face of the pressing block; a locking bolt for threaded connection with the support seat is provided in the first countersunk hole; and the screw head of the locking bolt is located in the locking groove.

[0010] The present invention is further configured such that: one end face of the mold head block is configured as an arc-shaped surface flush with the arc surface of the support base, and symmetrically arranged pressing grooves are provided on the mold head block located on one side of the arc-shaped surface, and the pressing grooves abut against one end face of the pressing block and the side face perpendicular to the end face.

[0011] The present invention is further configured such that the locking grooves are arranged collinearly, and the end faces of the pressing blocks on the side away from the pressing grooves are all flush with the side of the support base.

[0012] The present invention is further configured such that: the die block on the side away from the arc surface is provided with an annular chamfer, and the support base is provided with a plurality of symmetrically arranged second countersunk holes.

[0013] The present invention is further configured such that: an arc-shaped groove communicating with a connecting groove is provided on the die block on the side away from the arc-shaped surface; a punching groove communicating with the arc-shaped groove is provided through the die block on the side of the arc-shaped surface; and air holes distributed circumferentially and communicating with the arc-shaped groove are provided on the arc-shaped surface.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The die block is equipped with a cutting blade that works in conjunction with the stamping head to cut the material. The cutting blade can be replaced by the die block, and the sharpness of the new cutting blade ensures that the die block can meet the material cutting requirements. Compared with the traditional structure, only the die block needs to be replaced, while the support base remains in its original position and does not need to be replaced. Therefore, the cost is lower than that of the traditional structure, thus achieving the effect of cost reduction and efficiency improvement. The mounting groove is used to ensure the stable placement and limiting of the die block, making the position of the die block and its function more stable. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A type of thrust seat, such as Figure 1 and Figure 2 As shown, the structure includes a support base 1 for detachable connection with a drive roller. The support base 1 serves two purposes: firstly, it provides stable support and limits the various components; secondly, the installation of the support base 1 with the drive roller ensures stable installation of the entire structure with the drive roller, allowing the drive roller to move the entire structure and enabling the structure to function as a punch. The support base 1 is made of alloy steel, and one end face of the support base 1 is an arc surface with a radius matching that of the drive roller. A connecting groove 2 is formed through the center of the support base 1 in the thickness direction. A mounting groove 3, concentrically positioned at the opening of the connecting groove 2 on one side of the arc surface, is provided. A detachably connected die head block 4 is embedded within the mounting groove 3. The die head block 4 is made of mold steel. The high structural strength of mold steel is utilized to further enhance the overall structural strength and service life of the die block 4. The die block 4 is equipped with a cutting blade that works in conjunction with the stamping head to cut the material. The cutting blade can be replaced by replacing the die block 4. The sharpness of the new cutting blade ensures that the die block 4 can meet the material cutting requirements. Compared with the traditional structure, only the die block 4 needs to be replaced, while the support base 1 remains in its original position and does not need to be replaced. Therefore, the cost is lower than that of the traditional structure, thus achieving the effect of cost reduction and efficiency improvement. The mounting groove 3 is used to achieve stable placement and limit of the die block 4, making the position of the die block 4 and its function more stable.

[0023] like Figures 1-4As shown, the support base 1 located on one side of the arc surface has locking grooves 5 on both sides along its length, which are connected to the mounting groove 3. The locking groove 5 on the side away from the mounting groove 3 penetrates the support base 1. Each locking groove 5 has a detachable clamping block 6 for clamping the die head block 4. One side of the clamping block 6 in the width direction abuts against and clamps the die head block 4. A clearance is left between the length of the clamping block 6 and the wall of the locking groove 5. This clearance allows for easier placement of the clamping block 6 into the locking groove 5, making it easier to replace the die head block 4. The clamping block 6 is rectangular and its thickness is less than the depth of the locking groove 5. This design ensures that the clamping block 6 can... The clamping block 6 is fully housed within the locking groove 5 to prevent it from protruding out of the locking groove 5 and interfering with the overall structure's impact on the drive roller and the material cutting process. A first countersunk hole 7 is provided on the end face of the clamping block 6, and a locking bolt 8 for threaded connection with the support base 1 is provided in the first countersunk hole 7. The screw head of the locking bolt 8 is located in the locking groove 5, and a threaded hole for threaded connection with the locking bolt 8 is provided on the inner bottom surface of the locking groove 5. The first countersunk hole 7 is used to achieve stable placement and limiting of the screw head of the locking bolt 8, increasing the contact area at the connection between the locking bolt 8 and the clamping block 6, making the locking bolt 8's function of locking and limiting the clamping block 6 more stable, and making the clamping block 6's function of pressing and limiting the die head block 4 more stable.

[0024] like Figures 1-4 As shown, one end face of the die head block 4 is set as an arc-shaped surface flush with the arc surface of the support base 1. Symmetrically arranged clamping grooves 9 are formed on the die head block 4 located on one side of the arc-shaped surface. The clamping grooves 9 abut against one end face of the clamping block 6 and the side face perpendicular to the end face. This arrangement enables the clamping block 6 to stably limit the die head block 4 during the process of sliding off the support base 1, so that the clamping block 6 can stably restrict the die head block 4 on the support base 1, so that the subsequent function of the die head block 4 can be stably realized. At the same time, the clamping block 6 can also realize the rotational freedom of the die head block 4. The stability limitation reduces the probability of the die block 4 rotating during use, making the position of the die block 4 and its function more stable. The locking groove 5 is collinear, which can be completed in one process when machining the locking groove 5, making the machining process of the support base 1 faster. The end face of the clamping block 6 on the side away from the clamping groove 9 is flush with the side of the support base 1. This setting reduces the interference of the clamping block 6 on the installation process between the overall structure and the drive roller, making the process of disassembling and installing the overall structure from the drive roller more stable.

[0025] like Figures 1-4As shown, the die head block 4 on the side away from the curved surface has an annular chamfer 10. The annular chamfer 10 is used to provide stable guidance for the die head block 4 during the process of being placed into the mounting groove 3, making the installation of the die head block 4 in the mounting groove 3 more convenient and making the replacement of the die head block 4 more convenient. The support base 1 has several symmetrically arranged second countersunk holes 11. The second countersunk holes 11 are used to stably place the internal hexagon bolts, so that the screw head of the internal hexagon bolts can be stably accommodated by the second countersunk holes 11, avoiding interference of the internal hexagon bolts with the overall structure during use. The die head block 4 has an arc-shaped groove 12 that communicates with the connecting groove 2. The die head block 4 located on one side of the arc surface has a punching groove 13 that communicates with the arc groove 12. The arc surface has circumferentially distributed air holes 14 that communicate with the arc groove 12. By setting the air holes 14 and the arc groove 12 on the die head block 4, the air holes 14 and the arc groove 12 can be replaced at the same time when the die head block 4 is replaced, thereby ensuring that the functions of the air holes 14 and the arc groove 12 are more stable. With the help of the punching groove 13 and the punching head, the overall structure can cut and process the raw material.
