Description

Pointer punching side mold components

technical field

The utility model relates to a mould, in particular to a pointer type stamping side mold assembly.

Background technique

In the punching of slender workpieces such as instrument pointers, due to the slender workpieces, thin and hard materials, traditionally, it is very difficult to punch such blanked parts, and the yield is relatively low, and often punched out workpieces There are many burrs on the edge, and the surface is uneven. In many cases, it is necessary to punch on the punching hole with a support block, and the punch also needs to be a hollow punch. In this way, it is not only easy to cause the punching hole and the support block The gap between them is blocked, and the punch is easy to break, and the complex pointer punch is not easy to process (as shown in Figure 6), which is not conducive to the long-term stable punching of the workpiece, and the efficiency is also low.

Utility model content

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a pointer punching side mold assembly capable of continuously and accurately punching pointer-like slender workpieces, which satisfies the needs of production enterprises for high production efficiency of pointer-like workpieces. high precision requirements.

The technical scheme adopted by the utility model to solve its technical problems: the pointer-type punching side mold assembly includes an upper mold and a lower mold, and the upper mold includes an upper template and a punch fixed on the upper template, and the punch is plugged There is a pressing plate on which a pair of inserting rods respectively distributed on both sides of the punch are fixed. The bottom surface of the upper template is provided with a hole 1 and a guide hole 2 whose cross-section is larger than hole 1. The top of the rod is fixed with a limit block 1 inserted in the guide hole 2, and a compression spring 1 is installed between the bottom surface of the upper template and the top surface of the pressure plate; The bottom surface of the third hole is provided with a hole four connected to the hole three and having a cross-section larger than the hole three. A support block is inserted at the third hole, and the bottom of the support block is fixed with a limit block two connected with the hole four. A vertical rod, a pair of hard boards are plugged into the vertical rods, and a rubber spring plugged on the vertical rods is arranged between the two hard boards. A group of symmetrically arranged ejector rods are fixed at the bottom of the limit block 2, and the ejector rods press At the hard plate at the top; a pair of positioning rods are arranged on the lower formwork; when the pressure plate does not press the top surface of the lower formwork, the distance between the bottom surface of the pressure plate and the bottom surface of the upper formwork is greater than the distance between the bottom surface of the punch and the bottom surface of the upper formwork The distance between two; the staggered distribution between the positioning rod and the support block; the upper template is fixed with a guide sleeve, the lower template is fixed with a guide post cooperating with the guide sleeve, and the guide post is equipped with a return spring one. The role of the support block here is to support the thin plate; the role of the positioning rod here is to install and position the thin plate for subsequent stamping of the punch; here the role of the vertical bar, hard plate, rubber spring, and ejector rod Yes, when the punch is used to stamp the thin plate to punch down the pointer workpiece, the support block can move together with the punch. Move to the same level as the lower template and send out the punched pointer workpiece (as shown in Figure 4).

Further improvement, a pair of insertion holes are opened on the lower formwork, each positioning rod is inserted into the insertion hole, and each positioning rod is driven up and down by a cylinder fixed on the lower formwork, and the top of the positioning rod is a tapered surface. Here, the positioning rod is driven by a cylinder and the top end is a tapered surface, so that the cylinder can be used to drive the positioning rod to move up and down, so that after the thin plate is punched out, the positioning hole on the thin plate does not need to be taken out from the positioning rod, thereby The continuous translation of the thin plate can continuously punch the thin plate, thereby improving the efficiency.

Further improvement, a cushioning piece is installed between the cylinder and the positioning rod. The cushioning piece includes a fixed block. The limit block three is connected to the longitudinal hole, and the compression spring two is installed between the limit block three and the bottom surface of the longitudinal hole; the piston rod of the cylinder is fixed at the fixed block. The function of the buffer here is that when the punch on the upper die punches the thin plate, the positioning rod does not need to be driven back to the insertion hole through the cylinder, but is pressed down by the pressure plate on the upper die through the buffer. In the process of pressing down, the thin plate is punched through the punch on the upper die at the same time. After punching, when the thin plate is moved in translation, use the cylinder to return the positioning rod to the insertion hole. The benefits of doing so are Compared with returning the positioning rod to the socket hole before punching, in this way, when the thin plate is being punched, the position will not shift indefinitely, so that the precision of the punched pointer workpiece is higher (such as Figure 4).

The beneficial effects of the utility model are: the structure design of the utility model is ingenious and reasonable. Firstly, the positioning holes on the sheet metal are matched with the positioning rods for the installation and positioning of the sheet material, and then the upper mold is moved down, and the upper mold The pressing plate presses the sheet material, and continues to move the upper die quickly, and the punch on the upper die quickly punches the sheet material. At this time, the support block is pressed. When the sheet material is sheared by the punching hole, the support The block plays the role of supporting and preventing the deformation of the blanked workpiece, and the edge is smoother and the burr is less, so it is worthy of popularization and application.
