Description

Technical Field

[0001] The invention belongs to the technical field of forging processing, and in particular relates to a universal die forging flash stripping combined device and a use method thereof. Background Art

[0002] During die forging, excess metal in the die cavity flows into the flash groove to form flash, which must be removed later. During the trimming process of die forgings, the flash is easily stuck on the punch and difficult to remove. To solve the above problem, the commonly used method is to install a special flash removal device on the trimming die to remove the flash stuck on the punch. The disadvantages of the prior art device are: 1. It is not very versatile. The more types of die forgings, the more special flash removal devices are required. Various types of flash removal devices will incur certain costs in the drawing design, raw material purchase, processing and manufacturing, etc. The costs are extremely high when accumulated over a long period of time. 2. The production of a special flash removal device requires a certain period of time, which affects the production schedule. Summary of the invention

[0007] The fixed base includes a bottom mounting end and an upper screw portion, and the bottom mounting end is inserted into the T-slot of the press workbench; the fixing nut is screwed in along the upper screw portion of the fixed base and tightened to the workbench surface; the lower section of the adjusting column is processed with a threaded hole, which is screwed in along the upper screw portion of the fixed base and adjusted to a corresponding height; the upper section of the adjusting column is a screw, and the strip-shaped claw body penetrates into the screw on the adjusting column through the long hole in the middle, and the strip-shaped claw body is pressed against the upper and lower step surfaces of the adjusting column by tightening the nut;

[0008] The pressure-bearing base includes a bottom fixed end and an upper screw portion, and the fixing nut is screwed into the upper end surface of the bottom fixed end along the upper screw portion of the pressure-bearing base; a threaded hole is processed on the lower section of the pressure-bearing column, and is screwed into the corresponding position along the upper screw portion of the pressure-bearing base; the upper section of the pressure-bearing column is a screw, which passes through the long hole in the middle of the strip claw body, and the strip claw body is pressed against the upper and lower step surfaces of the pressure column by tightening the nut; by rotating the pressure-bearing base, the lower end surface of the bottom fixed end of the pressure-bearing base is made to fit tightly against the surface of the workbench.

[0009] Furthermore, the side surface of the adjustment column is symmetrically grooved.

[0010] Furthermore, the side surface of the pressure-bearing column is symmetrically grooved.

[0011] Furthermore, after the single claw is installed, the gap between the tip of the strip-shaped claw body and the punch is 1 to 3 mm.

[0012] In addition, the present invention also proposes a method for using the above-mentioned universal die forging flash removal assembly device. According to the outer contour projection curve of the die forging on the parting surface, the single claw adopts the following assembly method:

The height of the strip claw body of each single claw is not in the same horizontal plane, and they are arranged accordingly according to the curvature of the flash surface;

[0016] When the flash cut is thicker, a two-claw superposition combination is used to contact and overlap the two single-claw strip claws to disperse the force, increase the tensile strength, and prevent deformation and damage during the flash removal process.

[0017] Furthermore, when a symmetrically distributed combination of multiple claws is adopted, each single claw adjusts the adjustment column and the relative position of the screw on the adjustment column in the long hole of the strip claw body so that the tip of the strip claw body reaches a predetermined position, and the pressure-bearing column is adjusted accordingly.

[0027] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0028] This embodiment proposes a universal die forging flash removal assembly device, which includes one or more single claws. Through appropriate adjustment and reasonable distribution of the single claws, the flash removal function of various die forgings can be achieved. Figure 1 As shown, it mainly includes a fixed base 1, a fixed nut 2, an adjusting column 3, a strip claw body 4, a fastening nut 5, a pressure-bearing column 6 and a pressure-bearing base 7.

[0029] The fixed base 1 includes a bottom mounting end and an upper screw portion, and the bottom mounting end is inserted into the T-slot of the press workbench; the fixing nut 2 is screwed into the upper screw portion of the fixed base 1 and tightened to the workbench surface; the lower section of the adjusting column 3 is processed with a threaded hole, which is screwed into the upper screw portion of the fixed base 1 and adjusted to an appropriate height; the upper section of the adjusting column 3 is a screw, and the strip claw body 4 passes through the long hole in the middle to penetrate the screw on the adjusting column 3, and the strip claw body 4 is pressed against the upper and lower step surfaces of the adjusting column 3 by tightening the nut 5.

[0030] The pressure-bearing base 7 includes a bottom fixed end and an upper screw portion, and the fixing nut 2 is screwed into the upper end surface of the bottom fixed end along the upper screw portion of the pressure-bearing base 7; a threaded hole is processed in the lower section of the pressure-bearing column 6, and is screwed into a suitable position along the upper screw portion of the pressure-bearing base 7; the upper section of the pressure-bearing column 6 is a screw, which passes through the long hole in the middle of the strip claw body 4, and the strip claw body 4 is pressed against the upper and lower step surfaces of the pressure column 6 by tightening the nut 5; by rotating the pressure-bearing base 7, the lower end surface of the bottom fixed end of the pressure-bearing base 7 is made to fit tightly against the surface of the workbench.

[0031] The side surfaces of the adjusting column 3 and the pressure-bearing column 6 are symmetrically grooved to facilitate clamping with tools such as wrenches.

[0032] After the single claw is installed, the gap between the tip of the strip claw body 4 and the punch should be 1 to 3 mm.

[0033] The principle of removing flash using a single claw is as follows: when the trimming die punch moves upward along with the slide of the press, the flash stuck on the punch surface rises together with the punch. When the flash contacts the tip of the strip claw body 4, it is subjected to downward pressure, and the punch continues to move upward. The downward pressure on the flash gradually increases until it exceeds the friction between it and the punch, causing the flash to separate from the punch.

[0034] According to the outer contour projection curve of the die forging on the parting surface, the single claw has the following specific combinations:

[0035] 1. Symmetrical distribution of multiple claws. When the projection curve is a symmetrical structure (such as plates, cakes, and rods), a number of single claws with equal numbers and roughly symmetrical positions are arranged on both sides of the trimming die. Each single claw adjusts the adjustment column 3 and the relative position of the screw on the adjustment column 3 in the long hole of the strip claw body 4 so that the tip of the strip claw body 4 reaches the predetermined position, and the pressure column 6 is adjusted accordingly. Each single claw is evenly stressed and has a good flash removal effect. Figure 2 shown.

[0036] 2. Asymmetric distribution combination of multiple claws. When the projection curve is an asymmetric structure, a number of single claws with different numbers and asymmetric positions are arranged on two or three sides of the trimming die. By adjusting the structure of each single claw, the force on each single claw is roughly uniform.

[0037] 3. Combination of high and low claws. When the projection curve is a spatial curve and is not in a plane, a number of single claws are distributed at appropriate positions around the trimming die, and the height of the strip claw body 4 of each single claw is not in the same horizontal plane, but is arranged accordingly according to the curvature of the flash surface.

[0038] 4. Two-claw combination. When the flash cut is thick, the contact area with the punch is large, and the friction force increases, the contact of the two strip-shaped claws 4 is superimposed to disperse the force to increase the tensile strength and prevent deformation and damage of some parts during the flash removal process. Figure 3 shown.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
