Description

Technical Field

[0001] The invention belongs to the technical field of forging tools, and in particular relates to a lightweight and easily disassembled wedge bar, and also relates to a design method for the lightweight and easily disassembled wedge bar. Background Art

[0002] Wedges are one of the commonly used tools for connecting parts. The common structure is a square bar with an inclination, one end of which has a large cross-sectional area and the other end has a small cross-sectional area, so it has a wedge-tightening effect. Since wedges generally connect fixed parts and movable parts (working parts), when replacing working parts, the wedges need to be removed first, and then the working parts are removed, so wedges generally need to be removed frequently.

[0003] In the field of hot working, the anvil and the anvil are also fixed with wedges, which are generally made of die steel. When producing products of different types or specifications, the corresponding anvils need to be replaced. At this time, the wedges need to be removed first. However, the temperature of the wedges and anvils during hot working is relatively high. Taking forging titanium alloy as an example, the heating temperature of the billet is as high as 1000℃ or more. Therefore, due to the effect of heat conduction, the temperature of the anvil in contact with the billet can reach 300℃~500℃, and the temperature of the wedge connected to the anvil can also reach more than 100 degrees. Due to the thermal expansion and contraction of the metal, the volume of the anvil and the wedge expands at high temperature, resulting in the wedge tightening force of the wedge increasing continuously, thereby increasing the difficulty of removing the wedge. In addition, the size and weight of the wedge are generally proportional to the weight of the processed billet. When used for forging a large single-weight billet weighing more than 4t, the length of the wedge is about 600~1200mm, and the single weight of the wedge made of 5CrNiMo die steel is about 15kg~30kg, which leads to a high labor intensity for on-site operators during disassembly and assembly. Summary of the invention

[0004] The purpose of the present invention is to provide a lightweight and easily disassembled wedge strip, so as to solve the problem that the existing wedge strip is heavy and difficult to disassemble after being heated.

[0005] Another object of the present invention is to provide a design method for a lightweight and easily disassembled wedge strip.

[0006] The technical solution adopted by the present invention is a lightweight and easily disassembled wedge strip, comprising a middle stress-bearing section, one end of which is connected to a first weight-reducing section, the other end of which is connected to a second weight-reducing section, and a groove is arranged at the bottom of the middle stress-bearing section and along its axial direction. The present invention is also characterized in that: The upper surface of the middle stress-bearing section is set as a slope, the end of the slope connected to the first weight-reducing section is higher than the end of the slope connected to the second weight-reducing section, the slope of the slope is 1:50, and both ends of the middle stress-bearing section extend out of the slot for assembling the anvil and the anvil by 30mm~150mm. The length of the groove is 1 / 3~2 / 3 of the length of the middle stress-bearing section, the width of the groove is 1 / 3~1 / 2 of the width of the middle stress-bearing section, and the depth of the groove is 1 / 3~1 / 2 of the minimum thickness of the middle stress-bearing section.

[0007] The thickness of the first weight-reducing section and the second weight-reducing section are both smaller than the thickness of the middle force-bearing section.

[0008] The lower surfaces of the middle force-bearing section, the first weight-reducing section and the second weight-reducing section are all plane and coplanar.

[0009] The upper surface of the first weight-reducing section includes a plane section A, an end of the plane section A close to the groove is connected to one end of the arc section A, and the other end of the arc section A is connected to the upper surface of the middle force-bearing section; the upper surface of the second weight-reducing section includes a plane section B, an end of the plane section B close to the groove is connected to one end of the arc section B, and the other end of the arc section B is connected to the upper surface of the middle force-bearing section.

[0010] 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.

[0011] An arrow B is engraved on the end surface of the first weight-reducing section away from the middle force-bearing section, and the arrow B points to the upper surface of the first weight-reducing section.

[0012] Another technical solution adopted by the present invention is a design method of a lightweight and easily detachable wedge strip, and the specific steps are as follows: Step 1, determining the total length of the wedge strip and the length of the groove according to the size of the anvil, and dividing the wedge strip from one end to the other into a first weight-reducing section, a middle force-bearing section, and a second weight-reducing section; Step 2, opening a groove at the bottom of the middle stress section according to the length of the groove; Step 3, machining the upper surface of the middle force-bearing section into an inclined surface; Step 4, process the upper surface of the first weight-reducing section and one end connected to the middle force-bearing section into arc segment A, and process the end of the arc segment A away from the middle force-bearing section to the end of the first weight-reducing section into plane segment A; process the arc segment B and plane segment B on the upper surface of the second weight-reducing section in the same way.

[0013] The present invention is also characterized in that: In step 1, both ends of the middle force-bearing section extend out of the slots of the anvil seat and the anvil tool assembly by 30 mm to 150 mm; In step 3, the end of the inclined plane connected to the first weight-reducing section is higher than the end of the inclined plane connected to the second weight-reducing section, and the slope of the inclined plane is 1:50.

[0014] In step 4, the thickness of the plane segment A and the plane segment B are both smaller than the thickness of the middle stress-bearing segment.

[0015] The beneficial effects of the present invention are: (1) The lightweight and easily disassembled wedge strip of the present invention significantly reduces the overall weight of the wedge strip by providing a middle force-bearing section, a first weight-reducing section, and a second weight-reducing section, and providing a groove, thereby reducing the labor intensity of on-site operators during disassembly and assembly; (2) The length of the groove of the light and easily disassembled wedge strip of the present invention is shorter than the length of the middle force-bearing section, which can effectively reduce the contact area between the wedge strip and the upper anvil while ensuring the load-bearing capacity of the wedge strip, thereby reducing the friction force when the wedge strip is disassembled and facilitating disassembly; (3) The wedge strip of the present invention is lightweight and easy to disassemble. A gap is provided between the upper surfaces of the first and second weight-reducing sections and the anvil and the anvil. During use, the upper surfaces of the first and second weight-reducing sections do not contact the anvil. On the one hand, weight reduction is achieved. On the other hand, the wedge strip is prevented from getting stuck after being heated by reducing the contact surface, thereby facilitating disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 The lightweight and easily disassembled wedge strip of the present invention has a structure as follows Figure 1 , Figure 2 and Figure 3As shown, it includes a middle force-bearing section 1, one end of the middle force-bearing section 1 is connected to a first weight-reducing section 3, and the other end of the middle force-bearing section 1 is connected to a second weight-reducing section 4. The middle force-bearing section 1 is used to ensure the load-bearing capacity to prevent deformation. A groove 2 is provided at the bottom of the middle force-bearing section 1 and along its axial direction. The length of the groove 2 is 1 / 3 to 2 / 3 of the length of the middle force-bearing section 1 (the length of the groove 2 is less than the length of the slot for assembling the anvil 11 and the anvil 12), and the width of the groove 2 is 1 / 3 to 1 / 2 of the width of the middle force-bearing section 1. The depth of the groove 2 is 1 / 3 to 1 / 2 of the minimum thickness of the middle force-bearing section 1. By setting the groove 2, the overall weight of the wedge bar can be reduced. The lower surfaces of the middle force-bearing section 1, the first weight-reducing section 3 and the second weight-reducing section 4 are all flat and coplanar. The length of the middle force-bearing section 1 is greater than the length of the slot where the anvil 11 and the anvil 12 are assembled. Specifically: both ends of the middle force-bearing section 1 extend out of the slot where the anvil 11 and the anvil 12 are assembled by 30 mm to 150 mm, and the lengths of the first weight-reducing section 3 and the second weight-reducing section 4 are equal. When in use, the second weight-reducing section 4 is inserted into the anvil 11 and the anvil 12 so that the end of the first weight-reducing section 3 and the end of the second weight-reducing section 4 are aligned with the two ends of the anvil 12. The groove 2 is located in the middle position of the card slot where the anvil 11 and the anvil 12 are assembled, and the part of the middle force-bearing section 1 that extends out of the card slot where the anvil 11 and the anvil 12 are assembled is the load-bearing part. Through this arrangement, the contact area between the wedge bar and the anvil 11 and the anvil 12 can be effectively reduced while ensuring the load-bearing capacity of the wedge bar, thereby reducing the friction during disassembly of the wedge bar and facilitating disassembly, while also reducing the overall weight of the wedge bar.

[0020] Example 2 The lightweight and easily disassembled wedge strip of the present invention has a structure as follows Figure 1 , Figure 2 and Figure 3 As shown, it includes a middle force-bearing section 1, one end of the middle force-bearing section 1 is connected to a first weight-reducing section 3, and the other end of the middle force-bearing section 1 is connected to a second weight-reducing section 4. The middle force-bearing section 1 is used to ensure the load-bearing capacity to prevent deformation. A groove 2 is arranged at the bottom of the middle force-bearing section 1 and along its axial direction. The length of the groove 2 is 1 / 3 to 2 / 3 of the length of the middle force-bearing section 1 (the length of the groove 2 is less than the length of the slot for assembling the anvil 11 and the anvil 12), and the width of the groove 2 is the width of the middle force-bearing section 1. The depth of the groove 2 is 1 / 3~1 / 2 of the minimum thickness of the middle force-bearing section 1. By setting the groove 2, the overall weight of the wedge bar can be reduced. The lower surfaces of the middle force-bearing section 1, the first weight-reducing section 3 and the second weight-reducing section 4 are all flat and coplanar. The length of the middle force-bearing section 1 is greater than the length of the slot where the anvil 11 and the anvil 12 are assembled. Specifically: both ends of the middle force-bearing section 1 extend out of the slot where the anvil 11 and the anvil 12 are assembled by 30mm~150mm.

[0021] Furthermore, the upper surface of the middle force-bearing section 1 is set as an inclined plane, and the end of the inclined plane connected to the first weight-reducing section 3 is higher than the end of the inclined plane connected to the second weight-reducing section 4, and the inclination of the inclined plane is 1:50. The setting of the inclined plane can ensure that the middle force-bearing section 1 fixes the anvil 11 and the anvil 12 without displacement.

[0022] Furthermore, both ends of the groove 2 are arranged in an arc shape, and the concave surfaces of the arcs at both ends are arranged opposite to each other.

[0023] Example 3 On the basis of Example 2, the thickness of the first weight reduction section 3 and the second weight reduction section 4 are both smaller than the minimum thickness of the middle force-bearing section 1, that is, the thickness of the first weight reduction section 3 and the second weight reduction section 4 are both smaller than the gap between the anvil 12 and the anvil seat 11. Therefore, during use, the upper surfaces of the first weight reduction section 3 and the second weight reduction section 4 do not contact the anvil 12 and the anvil seat 11. On the one hand, weight reduction is achieved, and on the other hand, the probability of the wedge bar getting stuck after heating is reduced by reducing the contact surface.

[0024] Example 4 On the basis of Example 3, the upper surface of the first weight-reducing section 3 includes a plane section A5, and one end of the plane section A5 close to the groove 2 is connected to one end of the arc section A6, and the other end of the arc section A6 is connected to the upper surface of the middle force-bearing section 1. By setting the arc section A6, the first weight-reducing section 3 can be smoothly connected to the middle force-bearing section 1 to improve the load-bearing capacity; the upper surface of the second weight-reducing section 4 includes a plane section B7, and one end of the plane section B7 close to the groove 2 is connected to one end of the arc section B8, and the other end of the arc section B8 is connected to the upper surface of the middle force-bearing section 1. By setting the arc section B8, the second weight-reducing section 4 can be smoothly connected to the middle force-bearing section 1 to improve the load-bearing capacity.

[0025] Example 5 On the basis of Example 4, an arrow A9 is engraved on the side wall of the first weight-reducing section 3, and the arrow A9 points to the second weight-reducing section 4. An arrow B10 is engraved on the end surface of the first weight-reducing section 3 away from the middle force-bearing section 1, and the arrow B10 points to the upper surface of the first weight-reducing section 3. By providing the arrows A9 and B10, the operator can be reminded of the specific direction of use when installing the wedge strip, so as to improve work efficiency.

[0026] like Figure 4As shown, when in use, the end pointed by arrow A9 is first inserted into the gap between the anvil 12 and the anvil 11 until the end of the second lightening section 4 is aligned with the end of the anvil 12, and the groove 2 is located at the center of the slot where the anvil 11 and the anvil 12 are assembled. The portion of the middle force-bearing section 1 that extends out of the slot where the anvil 11 and the anvil 12 are assembled is the load-bearing portion, and the upper surfaces of the first lightening section 3 and the second lightening section 4 are not in contact with the anvil 12 and the anvil 11. On the one hand, weight reduction is achieved, and on the other hand, the probability of the wedge bar getting stuck after being heated is reduced by reducing the contact surface.
