Description

Technical Field

[0001] This application belongs to the field of metallurgical auxiliary tool technology, specifically relating to a shear blade assembly and disassembly tool. Background Technology

[0002] In the iron and steel metallurgy industry, to ensure the quality of metal smelting, simultaneous sample testing of round metal materials (bar stock) is required. During the testing process, after a simple removal of the outer oxide layer, the bar stock needs to be quantitatively cut using a shearing machine. The cut sample particles can then be directly tested. After prolonged use, the shearing blades of the shearing machine are prone to chipping and wear, requiring replacement. However, in practice, replacing new shearing blades presents inconvenience. Utility Model Content

[0003] This application aims to at least partially address one of the technical problems in the related art.

[0004] To address the aforementioned technical problems, this application provides a shear blade assembly and disassembly fixture. This fixture facilitates the installation and removal of the shear blade from the base, improves operational convenience, and avoids production delays caused by difficulties in assembling and disassembling the shear blade.

[0005] The technical solution adopted to achieve the purpose of this application is as follows:

[0006] The shear blade assembly and disassembly fixture of this application includes:

[0007] The base body is provided with a mating hole;

[0008] Two clamping blocks are mounted on the base body. At least one of the clamping blocks is adjustable in the relative direction of the two clamping blocks, and the two clamping blocks are used to clamp and fix the base on which the shear blade is mounted.

[0009] A pushing unit is provided on the base body. The pushing unit includes a pushing member and a driving member. The pushing member is fitted into the mating hole and is used to move along the mating hole to push the shear blade away from or into the base. The driving member is connected to the pushing member and is used to drive the pushing member to move.

[0010] In some technical solutions, one of the base and at least one of the clamping blocks is provided with a track, and the other is provided with a groove. The track extends in opposite directions of the two clamping blocks and engages in the groove to allow the clamping block to slide relative to the base.

[0011] In some technical solutions, the two clamping blocks are a first clamping block and a second clamping block, the first clamping block is adjustable along the track, and the second clamping block is fixed to the seat by a first fastener.

[0012] In some technical solutions, the base is provided with multiple mating holes, which are evenly distributed on the base. The track is divided into two spaced track segments, and the two clamping blocks are respectively assembled on the two track segments. The multiple mating holes are all located between the two track segments.

[0013] In some technical solutions, an elastic element is included, which is connected between the two clamping blocks. The elastic element is used to drive the two clamping blocks closer together to clamp and fix the base between the two clamping blocks.

[0014] In some technical solutions, both ends of the elastic element are provided with second fasteners, and the two second fasteners are respectively connected and fixed to the two clamping blocks.

[0015] In some technical solutions, the clamping block is provided with a groove, which is located on the inner side of the clamping block facing another clamping block. The openings of the two grooves are arranged opposite to each other, and the groove is used for the base to be inserted to achieve the limiting of the clamping block and the base.

[0016] In some technical solutions, a pad is provided in the groove, the pad is fixed to the groove wall, and the pad is used to increase the friction with the base.

[0017] In some technical solutions, the driving component includes a rocker arm and a crank handle. The pusher is threaded into the mating hole. The rocker arm is connected between the pusher and the crank handle. The crank handle is used to drive the pusher to rotate so as to move the pusher within the mating hole.

[0018] In some technical solutions, the position of the rocker arm relative to the pusher is adjustable to achieve adjustable lever arm size between the rocker arm and the pusher.

[0019] As can be seen from the above technical solution, the shear blade assembly and disassembly fixture of this application facilitates the installation and disassembly of the shear blade from the base, improves the convenience of operation, and avoids the situation where production is easily delayed due to the difficulty in assembling and disassembling the shear blade.

[0033] The specific technical solutions of this application will be described in detail below with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all drawings including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0034] It should be noted that this application is based on the inventor's discovery and understanding of the following facts and problems:

[0035] Currently, due to structural size limitations of shearing machines and industry design inertia, manufacturers of electromechanical equipment generally use closed embedded assembly for shear blade assembly. When installing the shear blade, a rubber hammer is needed to knock the blade into the base. This not only poses a risk of hand injury from hammering, but also easily causes deformation of the vertical sliding module under external force, resulting in module failure, shearing or springback malfunctions.

[0036] Secondly, the current common method for disassembling the shear blade is to "pry" it out. This requires using a flat, sharp tool to "pry" the blade out along the edge seam or pre-drilled operating hole. If the shear blade or installation compartment is corroded or deformed, disassembly becomes extremely difficult, time-consuming, and often necessitates replacing the entire blade holder and sliding module to maintain production schedules. This disrupts production and results in unnecessary waste of related components, urgently requiring improvement.

[0037] Based on the above facts and problems, this application provides a tooling for assembling and disassembling shear blades.

[0038] The following describes an embodiment of the shear blade assembly / disassembly fixture of this application.

[0039] like Figure 1 As shown, the shear blade assembly and disassembly fixture of this application embodiment includes a base 1, two clamping blocks 2 and a pushing unit 3.

[0040] The base 1 is provided with a mating hole 11. For example, as Figure 1 As shown, the base 1 can be roughly rectangular, and can be arranged vertically and extend along the left and right directions. The mating hole 11 can be a round hole, which can be located at the center of the base 1 and can penetrate the base 1 along the thickness direction (front and back direction).

[0041] It should be noted that each direction in this application can be the corresponding position in the actual use of the shear blade assembly and disassembly tool. The base 1 can be arranged to extend along the left and right direction, with the front side from right to left as the front, the rear side from right to left as the rear, the upper side from right to left as the upper, and the lower side from right to left as the upper.

[0042] Both clamping blocks 2 are assembled on the base 1. At least one clamping block 2 is adjustable in the relative direction of the two clamping blocks 2, and the two clamping blocks 2 are used to clamp and fix the base on which the shear blade is assembled.

[0043] For example, such as Figure 1 As shown, the clamping block 2 can also be a block-shaped structure. The two clamping blocks 2 can be arranged opposite each other in the left-right direction and can both be installed on the front side of the base 1. One clamping block 2 can slide freely relative to the base 1 in the left-right direction, while the other clamping block 2 can be fixed to the base 1. In use, the base 1 can be clamped and fixed between the two clamping blocks 2. Since the position of one of the clamping blocks 2 relative to the base 1 is adjustable, it is convenient to place the base 1 between the two clamping blocks 2 or remove the base 1 from between the two clamping blocks 2. On the other hand, it also meets the adaptability to bases of different sizes and specifications.

[0044] In other embodiments, both clamps 2 can slide relative to the base 1.

[0045] The push unit 3 is located on the base 1. The push unit 3 includes a push member 31 and a drive member 32. The push member 31 is fitted into the mating hole 11. The push member 31 is used to move along the mating hole 11 to push the shear blade away from or into the base. The drive member 32 is connected to the push member 31 and is used to drive the push member 31 to move.

[0046] For example, the jacking unit 3 can be arranged on the rear side of the base 1, the jacking member 31 can be a rod-shaped structure, the jacking member 31 can be assembled in the aforementioned mating hole 11, and the jacking member 31 can reciprocate within the mating hole 11 in the front-back direction. The driving component 32 can be a linear drive, for example, a hydraulic cylinder.

[0047] The driving component 32 is connected to the rear end of the pusher 31. In use, the driving component 32 can drive the pusher 31 to move back and forth. When the pusher 31 moves forward, it can push the shear blade inside the base 1. The shear blade can be removed from the base 1 under the pushing action of the pusher 31, thus facilitating the disassembly of the shear blade.

[0048] Secondly, during the installation process, the shear blade can be placed into the base 1 first. At this time, the shear blade is not fully placed in place. Then, the base 1 can be clamped and fixed between the two clamping blocks 2. Then, the driving component 32 can drive the pushing component 31 to push the shear blade into place, which also facilitates the installation of the shear blade.

[0049] In some embodiments, one of the base 1 and at least one clamping block 2 is provided with a track 12, and the other is provided with a groove 21. The track 12 extends in opposite directions of the two clamping blocks 2 and is fitted into the groove 21 so that the clamping block 2 is slidable relative to the base 1.

[0050] For example, such as Figure 2 As shown, the track 12 can be integrally formed on the front side of the seat 1. The track 12 can be a T-shaped track 12, that is, the cross-section of the track 12 can be T-shaped. The track 12 can be located in the middle of the seat 1 in the vertical direction, and the track 12 extends in the horizontal direction.

[0051] like Figure 3 As shown, each of the two clamping blocks 2 can be provided with a sliding groove 21 on its rear side. The sliding groove 21 on each clamping block 2 can penetrate the clamping block 2 in the left-right direction, and the shape of the sliding groove 21 can be adapted to the shape of the aforementioned track 12. During assembly, the aforementioned track 12 can be respectively assembled into the sliding groove 21 of the two clamping blocks 2, thereby satisfying the sliding needs of the clamping blocks 2 relative to the base 1, and also giving the clamping blocks 2 good sliding guidance, while also ensuring the structural strength of the sliding assembly.

[0052] In some embodiments, the two clamping blocks 2 are a first clamping block 22 and a second clamping block 23, respectively. The first clamping block 22 is adjustable along the track 12, and the second clamping block 23 is fixed to the base 1 by a first fastener 4. For example, as Figure 3 As shown, the first clamping block 22 can be the clamping block 2 located on the right side of the two clamping blocks 2, and the second clamping block 23 can be the clamping block 2 located on the left side of the two clamping blocks 2. The structures of the first clamping block 22 and the second clamping block 23 can be the same and can be arranged symmetrically in the left and right directions.

[0053] The first clamping block 22 can be slidably mounted on the aforementioned track 12, and the track 12 can also be fitted into the sliding groove 21 of the aforementioned second clamping block 23. The first fastener 4 can be a bolt or a screw, such as... Figure 2 As shown, a fixing hole 13 may be provided on the left side of the base 1, and the fixing hole 13 may also penetrate the base 1 in the front-back direction. The first fastener 4 can pass through the fixing hole 13 and can be threaded into the threaded hole on the second clamping block 23, thereby locking the position of the second clamping block 23.

[0054] In some other embodiments, the first fastener 4 can also be threaded into the fixing hole 13, and the first fastener 4 can abut against the rear side of the second clamping block 23, thereby also fixing the second clamping block 23.

[0055] In some embodiments, the base 1 is provided with a plurality of mating holes 11, which are evenly distributed on the base 1. The track 12 is separately provided and includes two track segments 121 arranged at intervals. Two clamping blocks 2 are respectively assembled on the two track segments 121, and the plurality of mating holes 11 are all located between the two track segments 121.

[0056] For example, such as Figure 4 As shown, there can be five mating holes 11. One mating hole 11 can be located in the center, and the other four mating holes 11 can be located around the mating hole 11 in the center and arranged at intervals along the circumference of the mating hole 11. These four mating holes 11 can be arranged in a dead angle.

[0057] The track 12 can be divided into two independent parts, namely track segments 121. Both track segments 121 extend in the left-right direction and can be spaced apart in the left-right direction. The five mating holes 11 mentioned above can be provided between the two track segments 121. The first clamping block 22 can be slidably assembled onto the right track segment 121, and the second clamping block 23 can be assembled onto the left track segment 121.

[0058] In use, the pushing parts 31 of the pushing unit 3 can be fitted into different mating holes 11, thereby enabling pushing of the shear blade at different positions and improving operational flexibility.

[0059] In some embodiments, the shear blade assembly / disassembly fixture includes an elastic element 5 connected between two clamping blocks 2. The elastic element 5 is used to drive the two clamping blocks 2 closer together to clamp and fix the base between the two clamping blocks 2.

[0060] For example, such as Figure 3 As shown, the elastic element 5 can be a spring, which can extend in the left-right direction. The left end of the elastic element 5 can be connected and fixed to the left clamping block 2, and the right end of the elastic element 5 can be connected and fixed to the right clamping block 2. In use, the elastic element 5 can apply a force to the two clamping blocks 2 to bring them closer together, so that the two clamping blocks 2 can clamp and fix the base, thus meeting the self-clamping and fixing requirements.

[0061] In some embodiments, both ends of the elastic member 5 are provided with second fasteners 6, and the two second fasteners 6 are respectively connected and fixed to the two clamping blocks 2. For example, as Figure 3 As shown, the second fastener 6 can also be a bolt. The left end of the elastic element 5 can be sleeved on the outer periphery of the second fastener 6 on the left side, and the right end of the elastic element 5 can be sleeved on the outer periphery of the second fastener 6 on the right side.

[0062] Each of the two clamping blocks 2 can be provided with an assembly hole 24. The assembly hole 24 can be T-shaped. The two second fasteners 6 can be threaded into the corresponding assembly holes 24 respectively, while the elastic element 5 can pass through the horizontal hole section of the corresponding assembly hole 24, which facilitates the connection and fixation of the elastic element 5 and the corresponding clamping block 2, and also ensures the structural stability of the fixation.

[0063] In some embodiments, the clamping block 2 is provided with a groove 25, which is located on the inner side of the clamping block 2 facing another clamping block 2. The openings of the two grooves 25 are arranged opposite to each other, and the grooves 25 are used for the base to be inserted to achieve the limiting of the clamping block 2 and the base.

[0064] For example, such as Figure 3 As shown, the groove 25 can be a rectangular groove. The groove 25 of the left clamping block 2 can be located on the right side of the clamping block 2, and the groove 25 of the right clamping block 2 can be located on the left side of the clamping block 2. The two grooves 25 can pass through the corresponding clamping blocks 2 in the vertical direction. In use, the left and right sides of the base can be respectively embedded in the corresponding grooves 25, thereby improving the stability of clamping and fixing the base.

[0065] In some embodiments, a pad 26 is provided in the groove 25. The pad 26 is fixed to the groove wall of the groove 25 and is used to increase the friction with the base. For example, the pad 26 can be a rubber pad, the pad 26 can be rectangular in shape, and two pads 26 are provided. The two pads 26 can be respectively attached and fixed to the groove wall on the front side of the corresponding groove 25.

[0066] For example, each pad 26 can have two cylindrical structures integrally formed on its front side, and the clamping block 2 can be provided with two positioning holes. The two cylindrical structures can be inserted into the two positioning holes, which facilitates the connection and fixation of the pad 26 and the clamping block 2.

[0067] When the seat 1 is fitted into the groove 25, the pad 26 can increase the friction with the surface of the seat 1, thereby improving the limiting and fixing effect on the seat 1.

[0068] In some embodiments, the drive component 32 includes a rocker arm 321 and a crank handle 322. The pusher 31 is threaded into the mating hole 11. The rocker arm 321 is connected between the pusher 31 and the crank handle 322. The crank handle 322 is used to drive the pusher 31 to rotate so as to move the pusher 31 within the mating hole 11.

[0069] For example, such as Figure 5As shown, the pusher 31 can be a screw structure, meaning that the outer periphery of the pusher 31 can be provided with external threads. The mating hole 11 can be a threaded hole, and the pusher 31 is threadedly assembled into the mating hole 11. The rear end of the pusher 31 can be provided with a through hole that penetrates the pusher 31 radially. The rocker arm 321 can be a round rod shape, and the rocker arm 321 can be assembled into the through hole. The handle 322 can be fixed to the end of the rocker arm 321, and the handle 322 can extend along the front-back direction.

[0070] When in use, the hand can hold the crank 322. By turning the crank 322, the pusher 31 can be driven to rotate in the mating hole 11. Under the action of the threaded engagement between the pusher 31 and the mating hole 11, the pusher 31 can move in the front and back direction, thereby realizing the push of the shear blade.

[0071] In some embodiments, the position of the rocker arm 321 relative to the pusher 31 is adjustable to allow for adjustment of the lever arm between the rocker arm 322 and the pusher 31. For example, as Figure 5 As shown, the rocker arm 321 can reciprocate within the through hole of the pusher 31, thereby enabling adjustment of the lever arm length between the rocker arm 322 and the pusher 31, meeting different driving needs.

[0072] The pusher 31 may also be provided with a third fastener 33, which may be a bolt or a screw. The third fastener 33 may be threaded onto the pusher 31. After the position of the rocker arm 321 relative to the pusher 31 is adjusted, the third fastener 33 can be screwed onto the rocker arm 321 to fix the position of the rocker arm 321, thereby fixing the adjusted lever arm length.

[0073] The following describes a specific example of the shear blade assembly / disassembly fixture of this application.

[0074] This tooling mainly consists of three parts: clamping block 2, base 1, and pushing unit 3.

[0075] There are two clamping blocks 2, designated as a left clamping block 2 and a right clamping block 2. Each clamping block 2 is equipped with a tension spring, bolts, etc. The left and right clamping blocks 2 are a pair of identical, irregularly shaped steel structures, symmetrically installed on the left and right sides of the track 12 of the base 1. The rectangular notch between them is a reserved space for matching the structure of the shearing machine. The right clamping block 2 can be fixed to the right end of the track 12 with a set bolt as a fixed clamping block 2, while the left clamping block 2 can be adjusted along the track 12 according to the actual environment. The two clamping blocks 2 are connected by a tension spring. The main function of the clamping blocks 2 is to fix and adjust the position of this fixture during operation. The tension spring provides constraint force to the left sliding clamping block 2, thus achieving the clamping and fixing function of the two clamping blocks 2.

[0076] The base 1 is made of high-strength alloy steel. Base 1 primarily connects the various components and transmits the working torque during the operation of the lead screw. An M6 positive-rotation single-threaded hole is formed along the horizontal direction at the geometric center of base 1. This threaded hole cooperates with the ejector lead screw of the rocker arm 321 assembly to complete the disassembly and installation of the shear blade. An internal threaded hole can also be formed on the right end, using a set bolt to fix the position of the right slider.

[0077] The jacking unit 3 mainly consists of an ejector screw (jacking component 31), a variable pitch rocker arm 321, and a crank handle 322. The screw is made of high-strength wear-resistant alloy steel, and its overall Φ6 triangular external thread matches the internal thread at the center of the track 12, serving as the direct working structure for disassembling the shear blade. The variable pitch rocker arm 321 is cylindrical in shape and serves as the torque input device for the ejector screw; its transmitted torque can increase or decrease with changes in the effective working length. The crank handle 322 can be a hollow cylinder, with roller bearings installed inside. These roller bearings allow for free rotation of the gripping part of the crank handle 322, thereby improving work efficiency.

[0078] In use, the fixed (right) clamp 2 is secured to the right side of the base of the track 12 by a set bolt, and connected to the left clamp 2 by a tension spring. Together, they complete the overall structural fixation function, forming a functional structural foundation and providing torque support for the lead screw. The lead screw component of the hand crank 321 engages with the internal thread on the base of the track 12, and rotates forward under the drive of the crank handle of the hand crank 321. At the same time, the lead screw generates axial linear motion to push the shear blade out (in) the base. In use, the torque and rotation speed can also be adjusted by changing the distance between the crank handle and the rotation axis to adapt to different working conditions.
