Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of forging tools, and particularly relates to a light and easy-to-disassemble wedge strip and a design method of the light and easy-to-disassemble wedge strip. BACKGROUND

[0002] The wedge strip is one of commonly used tools for connecting parts, and a common structure is a square strip with an inclination, one end of which has a large cross-sectional area and the other end has a small cross-sectional area, so as to have a wedge tightening effect. Since the wedge strip is generally connected to a fixed part and a movable part (a working part), when the working part is replaced, the wedge strip needs to be disassembled first, and then the working part is disassembled, so the wedge strip generally needs to be frequently disassembled.

[0003] In the field of hot processing, an anvil and an anvil tool are also assembled and fixed by using a wedge strip, and generally, a die steel is used as a material, and different types or specifications of products need to be replaced with corresponding anvils, at which time the wedge strip needs to be disassembled first. However, the temperature of the wedge strip and the anvil tool during the hot processing is relatively high. For example, in the case of forging titanium alloy, the heating temperature of the blank is as high as 1000°C or more, so due to the effect of heat conduction, the temperature of the anvil tool in contact with the blank can reach 300°C to 500°C, and the temperature of the wedge strip connected to the anvil tool can also reach hundreds of degrees. Due to the thermal expansion and contraction of the metal, the volume of the anvil tool and the wedge strip expands at high temperature, which causes the wedge tightening force of the wedge strip to continuously increase, thereby increasing the difficulty of disassembling the wedge strip. In addition, the size and weight of the wedge strip are generally proportional to the weight of the processed blank. When a large single-weight blank with a weight of more than 4t is forged, the length of the wedge strip is about 600-1200mm, and the weight of the wedge strip made of 5CrNiMo die steel is about 15kg-30kg, thereby causing a large labor intensity of the on-site operator during disassembly. SUMMARY

[0004] The purpose of the present application is to provide a light and easy-to-disassemble wedge strip to solve the problems of large weight and difficult disassembly after heating of the existing wedge strip.

[0005] Another purpose of the present application is to provide a design method of the light and easy-to-disassemble wedge strip.

[0007] The present application is characterized in that,

[0008] The upper surface of the middle stress section is provided as an inclined surface, the end connected with the first weight-reducing section is higher than the end connected with the second weight-reducing section, the inclination of the inclined surface is 1:50, the two ends of the middle stress section extend out of the clamping groove 30mm~150mm assembled with the anvil and the anvil tool, the length of the groove is 1 / 3~2 / 3 of the length of the middle stress section, the width of the groove is 1 / 3~1 / 2 of the width of the middle stress section, and the depth of the groove is 1 / 3~1 / 2 of the minimum thickness of the middle stress section.

[0009] The thicknesses of the first weight-reducing section and the second weight-reducing section are both less than the thickness of the middle stress section.

[0010] The lower surfaces of the middle stress section, the first weight-reducing section and the second weight-reducing section are all planes and are coplanar.

[0011] The upper surface of the first weight-reducing section comprises a plane section A, one end of the plane section A close to the groove is connected with one end of a circular arc section A, and the other end of the circular arc section A is connected with the upper surface of the middle stress section; the upper surface of the second weight-reducing section comprises a plane section B, one end of the plane section B close to the groove is connected with one end of a circular arc section B, and the other end of the circular arc section B is connected with the upper surface of the middle stress section.

[0012] An arrow A is engraved on the side wall of the first weight-reducing section, and the arrow A points to the second weight-reducing section.

[0013] An arrow B is engraved on the end surface of the first weight-reducing section away from the middle stress section, and the arrow B points to the upper surface of the first weight-reducing section.

[0014] Another technical solution adopted by the present application is a design method of the light and easy-to-disassemble wedge strip, and the specific steps are as follows:

[0015] Step 1, according to the size of the anvil, the total length of the wedge strip and the length of the groove are determined, and the wedge strip is sequentially divided into a first weight-reducing section, a middle stress section and a second weight-reducing section from one end to the other end;

[0016] Step 2, according to the length of the groove, a groove is opened at the bottom of the middle stress section;

[0017] Step 3, the upper surface of the middle stress section is machined as an inclined surface;

[0018] Step 4, the upper surface of the first weight-reducing section and the end connected with the middle stress section is machined as a circular arc section A, and the end of the circular arc section A away from the middle stress section to the end of the first weight-reducing section is machined as a plane section A; in the same way, a circular arc section B and a plane section B are machined on the upper surface of the second weight-reducing section.

[0019] The present application is characterized in that,

[0020] In step 1, the two ends of the middle stress section extend out of the clamping groove 30mm~150mm assembled with the anvil and the anvil tool;

Step 2: According to the length of the groove (2), a groove (2) is opened at the bottom of the middle stress section (1); Step 3: Machin the upper surface of the middle stress section (1) into an inclined surface; Step 4: The upper surface of the first weight-reducing section (3) and the end connected to the middle force-bearing section (1) is machined into an arc segment A (6), and the end of the arc segment A (6) away from the middle force-bearing section (1) to the end of the first weight-reducing section (3) is machined into a flat segment A (5); the same method is used to machine an arc segment B (8) and a flat segment B (7) on the upper surface of the second weight-reducing section (4).

6. The design method for the lightweight and easily detachable wedge strip according to claim 5, characterized in that, In step 1, both ends of the middle force-bearing section (1) extend 30mm~150mm out of the slots for assembling the anvil seat (11) and the anvil (12); In step 3, the end of the inclined plane connected to the first weight reduction section (3) is higher than the end of the inclined plane connected to the second weight reduction section (4), and the slope of the inclined plane is 1:

50.

7. The design method for the lightweight and easily detachable wedge strip according to claim 5, characterized in that, In step 4, the thickness of both planar segment A (5) and planar segment B (7) is less than the minimum thickness of the middle stress segment (1).
