Description

Technical Field

[0001] The utility model relates to the technical field of metal piece forming, in particular to an auxiliary positioning device for metal piece forming. Background Art

[0002] In modern metal parts forming technology, compression molding is a commonly used molding method. The molding equipment is usually divided into upper and lower molds. The material is placed between the upper and lower molds, and the workpiece is pressed together by the effect of stamping. At this stage, metal parts require the upper and lower molds to match the height during compression molding. If the upper and lower molds are installed, screws and pins are usually used to fix the position of the molds, and the movement is stabilized by guide rods and guide grooves during movement.

[0003] However, existing compression molding equipment is often only equipped with a simple limit frame when positioning the material. When the stamping material is placed, the operator needs to align the limit frame to place the material, which is inefficient. At the same time, after the compression molding is completed, the formed workpiece cannot be quickly taken out.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides an implementation scheme: an auxiliary positioning device for metal part forming, the equipment is provided with a molding frame 1, a support frame is provided on the molding frame 1, the support frame is used to fix the support plate, the stamping cylinder 2 is assembled on the support plate, the telescopic end of the stamping cylinder 2 is provided with a lifting seat 3, the lifting seat 3 is equipped with an upper molding die 6, the lifting seat 3 is driven by the telescopic end of the stamping cylinder 2 to slide up and down, a lower support seat 4 is provided on the molding frame 1, the lower support seat 4 is equipped with a lower molding die 5, so as to drive the upper molding die 6 to slide up and down, and the upper molding die 6 and the lower molding die 5 correspond to each other, and the mutual extrusion of the two can be used to stamp and match the metal parts;

[0024] Two pairs of material centralizers 7 are arranged around the outer ring of the lower support base 4. When in use, the material is placed on the lower pressing die 5. The lower support base 4 is a rectangular plate. Each material centralizer 7 corresponds to a side parallel to the lower support base 4. By synchronously controlling the posture of each material centralizer 7, the side of the material can be quickly guided and straightened to ensure the correct posture of the material.

[0025] According to the instruction manual Figure 1-3 It can be seen that the material centralizer 7 is movably mounted on the molding machine frame 1 via the rotating shaft 8. The molding machine frame 1 is provided with a control structure, through which the postures of the two pairs of material centralizers 7 are synchronously adjusted;

[0026] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned control structure includes a telescopic cylinder 9, which is provided on the molding machine frame 1. The telescopic cylinder 9 is connected to the telescopic end of the telescopic cylinder 9. The molding machine frame 1 is provided with a pipe column 11. The pipe column 10 is sleeved on the pipe column 11. Two pairs of connecting rods 12 extend from the outside of the pipe column 10. The two pairs of connecting rods 12 are connected to the two pairs of material centralizers 7;

[0027] During the specific implementation process, the control structure adjusts the posture of the material straightener 7 synchronously, and pushes the pipe column 11 to move in the pipe sleeve 10 through the telescopic cylinder 9, so that the pipe column 11 drives the two pairs of connecting rods 12 to move, and the material straightener 7 movably connected by the two pairs of connecting rods 12 rotates. The material straightener 7 rotates with the rotating shaft 8 as the axis, and the two pairs of material straighteners 7 synchronously move toward the center, gradually pushing the material into the correct posture in the process. After the two pairs of material straighteners 7 are fully moved into place, they will wrap the material to fix the material. It should be pointed out that by connecting the telescopic cylinder 9 and the punching cylinder 2 to the same pump station, and using the same pump station to synchronously control the status of the telescopic cylinder 9 and the punching cylinder 2, the punching action is more continuous and the punching is more precise.

[0031] As a preferred solution, further, the rectangular groove 13 is a hollow groove body with a rectangular structure, and a through hole 14 is opened on the rectangular groove 13 to match the connecting rod 12 to facilitate the movement adjustment of the connecting rod 12.

[0032] As a preferred solution, further, one side of the material centralizer 7 is a sloped structure.

A control structure synchronized with the stamping cylinder 2 is designed to control the posture of the material straightener 7, and then use the material straightener 7 to automatically wrap, limit and fix the metal part material. It automatically opens after the stamping is completed, which not only automatically corrects the posture of the material and limits it, but also makes it convenient to take it.
