Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to a stamping and shaping device for a reducer tube. Background Art

[0002] The raw material for pipe welding is plate. In actual use, reducers are often encountered in pipelines. Reducers, that is, pipes with different diameters, are mainly used to connect other pipes of different sizes. Reducers need to be reduced in diameter multiple times to meet the requirements. Reducers are generally formed by stamping round plates. However, during stamping, it is found that the shaped pipe fittings after stamping will adhere to the inner wall of the mold, making it impossible to quickly remove the reducer from the mold. This not only increases the workload of the staff, but also greatly reduces the work efficiency. Utility Model Content

[0003] In view of this, the present application provides a device for stamping and shaping a reducer pipe to solve the technical problem that the stamped and shaped pipe fittings are attached to the mold, which is time-consuming and labor-intensive to remove, resulting in reduced work efficiency.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A reducing tube stamping and shaping device, comprising:

[0006] An upper plate mounted on the slide of a punch press;

[0007] A male mold connected to the upper mold plate;

[0008] A lower plate mounted on the work table of a punch press;

[0009] The punch is movably connected to a pressing plate below the upper mold plate through a plurality of elastic mechanisms;

[0010] A concave mold connected to the lower mold plate;

[0011] A limiting sleeve disposed on the die;

[0012] A discharge mechanism disposed at the bottom of the lower template;

[0013] Among them, the circular plate to be punched is placed in the limiting sleeve, and the punching machine drives the upper template to move the pressure plate downward, so that the pressure plate is pressed on the circular plate in the limiting sleeve. At the same time, the punch is extended into the pressure plate to punch the circular plate. The circular plate is shaped in the die to obtain a pipe fitting. After the stamping is completed, the unloading mechanism lifts the pipe fitting upward for unloading.

[0014] Furthermore, the elastic mechanism comprises:

[0015] A guide rod connected to the lower end of the upper template;

[0016] A first compression spring is sleeved on the guide rod, and the first compression spring is abutted between the upper template and the pressure plate.

[0017] Furthermore, the guide rod is slidably matched with the pressure plate.

[0018] Furthermore, a limiting cover is provided at the lower end of the guide rod.

[0019] Furthermore, the unloading mechanism comprises:

[0020] An inner box disposed below the lower template;

[0021] a drive assembly connected to the inner box;

[0022] A discharge assembly is connected to the driving assembly, and the driving assembly works to drive the discharge assembly to move upward, thereby lifting the pipe fitting located in the female die.

[0023] Furthermore, the driving assembly comprises:

[0024] At least one driving gear connected to the output end of the driving motor;

[0025] at least one driven gear mounted in the inner housing, the driven gear meshing with a corresponding driving gear;

[0026] At least one connecting rod is hinged between the corresponding driven gear and the discharge assembly.

[0027] Furthermore, the unloading assembly comprises:

[0032] A discharge block connected to the top of the moving rod can be supported on the bottom of the pipe fitting to lift the pipe fitting for discharge.

[0033] Furthermore, an end cover is installed on the upper end of the cylinder, the lower end of the second compression spring is connected to the piston block through a spring seat, and the upper end of the second compression spring is in contact with the end cover.

[0034] Furthermore, the moving rod is slidably connected to the end cover.

[0035] Furthermore, the lower end of the pressing plate has a positioning boss adapted to the limiting sleeve.

[0036] It can be seen from the above technical solution that the advantages of the utility model are:

[0037] 1. An elastic mechanism is provided in the present application, and the elastic mechanism is connected between the upper template and the pressure plate. When the upper template drives the punch and the pressure plate to press downward, and the positioning boss of the pressure plate is pressed on the circular plate in the limiting sleeve, the upper template drives the punch to continue to move downward, and the punch stretches the circular plate, and the upper template squeezes the elastic mechanism. Therefore, the elastic mechanism can press the pressure plate on the limiting sleeve, thereby making the upper template and the punch firmly connected.

[0038] 2. In the present application, a discharge mechanism is provided. After the pipe fittings are stamped and formed, the discharge mechanism can lift the pipe fittings upwards, so that the staff can take the pipe fittings out of the die, which not only reduces the workload, but also makes the discharge speed faster, thereby improving work efficiency.
