Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a safe and portable wedge fastening device for a hammer holder. Background Technology

[0002] In the forging industry, hammer die holders all need to be fastened by using wedges. The conventional wedge structure is to process a steel bar into a size that is narrow at the front and wide at the back, and insert it into the mating surface of the die and the holder. Through impact, it gradually squeezes the die and the holder, thereby achieving the fastening effect.

[0003] Conventional wedges are long and heavy, and require continuous striking with a hammer or mallet during use. This process not only involves high labor intensity and harsh working conditions for workers, but also poses significant safety hazards, making accidents highly likely during handling and hammering.

[0004] Therefore, a safe and portable wedge-locking device for hammer holders is still needed to solve the above problems. Utility Model Content

[0005] This utility model provides a safe and portable wedge-shaped clamping device for hammers that solves the above-mentioned problems.

[0006] The objective of this utility model is achieved through the following technical solution: A safe and portable hammer holder with a wedge fastening device includes: a fixed block and a movable block that can slide relative to each other, with a sliding mating surface between the fixed block and the movable block, a first clamping surface formed on the side wall of the fixed block and a second clamping surface formed on the side wall of the movable block respectively, and the fixed block and the movable block slide relative to each other through the mating surface to adjust the distance between the two parallel sides projected on the horizontal plane by the first adjustment surface and the second adjustment surface.

[0007] Preferably, it further includes a driving component, wherein the first adjustment surface and the second adjustment surface are two non-parallel but mutually cooperating surfaces, the cooperating surfaces include at least two intersecting surfaces, and the driving component is used to drive the stationary block and the moving block to slide relative to each other along the cooperating surfaces.

[0008] Preferably, the drive assembly includes a connecting rod and a threaded adjustment part. The rod body passes through the fixed block and the moving block and then extends out to be threadedly connected to the threaded adjustment part. The fixed block and the moving block have through holes for the rod body to pass through. The end of the connecting rod is connected to the fixed block or the moving block. The inner side of the threaded adjustment part has a threaded hole that extends axially. The end of the connecting rod and the adjustment part correspond to the side wall of the fixed block, respectively.

[0009] Preferably, the end sidewall of the fixed block is provided with a receiving groove, the end portion of the connecting rod is inserted into the receiving groove, and a connecting hole is provided in the radial direction near the end of the connecting rod. A connecting member is rotatably connected in the connecting hole, and the connecting member extends out of the connecting hole and connects to the receiving groove. The threaded adjustment part fits into the connecting groove inside the end of the moving block, and the periphery of the threaded adjustment part is sealed to the connecting groove by a sealing ring.

[0010] Preferably, the mating surface includes a first sliding surface formed on the fixed block and the moving block respectively, and the moving directions of the two parallel surfaces that abut against the first sliding surface and the first adjusting surface and the second adjusting surface have an included angle.

[0011] Preferably, the mating surface further includes a second sliding surface that intersects the first sliding surface at an obtuse angle, so as to prevent the moving block and the stationary block from being misaligned along the adjustment direction perpendicular to the first adjustment surface and the second adjustment surface.

[0012] Preferably, an elastic element is sleeved on the end of the connecting rod near the inner side of the connecting rod, and the elastic element is elastically connected between the end of the connecting rod and the fixed block or the moving block.

[0014] Compared with the prior art, the beneficial effects of this utility model include at least the following: The system consists of a fixed block and a moving block that can slide against each other. When the fixed block and the moving block are initially aligned at their combined position, the distance between the parallel surfaces supported by the first clamping surface and the second clamping surface is minimized. As the fixed block and the moving block move relative to each other, the distance between the two parallel edges projected onto the horizontal plane by the first and second adjustment surfaces is adjusted, thereby adjusting the distance between the two supported planes. This allows for precise control of the distance between the two planes, enabling the forging mold to be clamped onto the base. Attached Figure Description

[0017] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0018] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0019] Reference Figure 1-6 This utility model provides a safe and portable wedge-shaped fastening device for a hammer holder, comprising: a fixed block 1 and a movable block 2 that can slide relative to each other. With the fixed block 1 as a reference, the movable block 2 moves relative to the fixed block 1, and with the movable block 2 as a reference, the fixed block 1 moves relative to the movable block 2. A sliding mating surface 3 is provided between the fixed block 1 and the movable block 2, wherein the surface of the mating surface 3 is a smooth plane. A first clamping surface 11 is formed on the side wall of the fixed block 1, and a second clamping surface 21 is formed on the side wall of the movable block 2, respectively, corresponding to the outer side of the mating surface 3. The fixed block 1 and the movable block 2 slide relative to each other through the mating surface 3 to adjust the distance between the two parallel edges projected onto the horizontal plane by the first adjustment surface 6 and the second adjustment surface 7. When moving relative to each other, the moving block 2 and the fixed block 1 move relative to each other along the mating surface 3. The two parallel surfaces supported by the first adjusting surface 6 and the second adjusting surface 7 move along a distance perpendicular to the relative movement of the moving block 2 and the fixed block 1. In actual use, the distance between the first adjusting surface 6 and the second adjusting surface 7 can be driven to move relative to each other with the help of external equipment, so that the mold can be gradually pushed and clamped onto the base through the first adjusting surface 6 and the second adjusting surface 7. This eliminates the need for workers to fix the mold base through complicated hammering or violent impact, reducing the labor intensity of workers and reducing the degree of danger.

[0020] Preferably, the system further includes a drive assembly 4. The first adjusting surface 6 and the second adjusting surface 7 are two non-parallel but mating surfaces. The mating surface 3 includes at least two intersecting planes, both of which have smooth surfaces to facilitate the movement of the first adjusting surface 6 and the second adjusting surface 7 relative to each other, pushing apart the two parallel surfaces. The drive assembly 4 is used to drive the stationary block 1 and the moving block 2 to slide relative to each other along the mating surface 3. The drive assembly 4 can use hydraulic or pneumatic grippers to clamp the two side walls of the stationary block 1 and the moving block 2 respectively. By driving the moving block 2 and the stationary block 1 to move relative to each other laterally, the mold base is pushed and fixed in a preset position, simplifying the labor intensity and reducing the risk factor for workers.

[0021] Reference Figure 4 and 5 The drive assembly 4 includes a connecting rod 41 and a threaded adjustment part 42. The rod body of the connecting rod 41 passes through the fixed block 1 and the moving block 2 and extends out to connect to the threaded adjustment part 42. The connecting rod 41 has an end and a rod body, with the diameter of the end being larger than the diameter of the rod body. The fixed block 1 and the moving block 2 have through holes 43 for the rod body of the connecting rod 41 to pass through. The end of the connecting rod 41 connects to the fixed block 1 or the moving block 2. The inner side of the threaded adjustment part 42 has a threaded hole 44 that extends axially. The end of the connecting rod 41 and the adjustment part correspond to the side wall of the fixed block 1, respectively. By manually turning the threaded adjustment part 42, the thread inside the threaded adjustment part 42 rotates and climbs along the thread of the extended connecting rod 41, thereby driving the fixed block 1 or the moving block 2 that the adjustment part is in contact with to move closer or further away, thus facilitating the adjustment of the clamping force of the mold base after it is fixed in a preset position. The extended part of the connecting rod 41 has external threads for matching with the threaded adjustment part 42. The cross-section of the through hole 43 is elliptical to prevent the connecting rod 41 from being bent.

[0022] Preferably, the end sidewall of the fixed block 1 is provided with a receiving groove 12, and the end portion of the connecting rod 41 is inserted into the receiving groove 12. The connecting rod 41 is provided with a connecting hole 411 in the radial direction near the end, and a connecting member 412 is rotatably connected in the connecting hole 411. The connecting member 412 extends out of the connecting hole 411 and connects to the receiving groove 12, and extends through the top and bottom holes of the receiving groove 12. The end of the connecting rod 41 is inserted into the receiving groove 12, which can largely avoid the end from collision damage and has a collision avoidance function. The connecting member 412 locks the connecting rod 41 in the rotation direction along the axis, preventing the connecting rod 41 from rotating when adjusting the threaded adjustment part 42, which would be detrimental to the relative displacement of the moving block 2 and the fixed block 1 along the axis, so as to smoothly drive the mold base to be fixedly attached to the preset position.

[0023] The threaded adjustment part 42 fits into the connecting groove 22 at the end of the moving block 2, and the periphery of the threaded adjustment part 42 is connected to the connecting groove 22 via an annular member 5. The periphery of the threaded adjustment part 42 also has an annular hole matching the shape of the annular member 5. Through the connection of the annular member 5, the threaded adjustment part 42 can rotate within the connecting groove 22, preventing it from falling off, avoiding loss, and simplifying the assembly process. The annular member 5 can be a rigid annular ring or a half-ring, serving to connect the threaded adjustment part 42 and the stationary block 1.

[0024] Preferably, the mating surface 3 includes a first sliding surface 31 formed on the fixed block 1 and the moving block 2 respectively. The movement directions of the two parallel surfaces that abut against the first sliding surface 31 and the first adjusting surface 6 and the second adjusting surface 7 are inclined at an angle. The first sliding surface 31 is an inclined surface, and the angle between the inclined surface and the displacement direction between the first adjusting surface 6 and the second adjusting surface 7 forms an inclined angle. After the two inclined surfaces move relative to each other along the axial direction, the width perpendicular to the axial direction gradually increases, thereby supporting mold bases of different sizes in various application scenarios.

[0025] Preferably, the mating surface 3 further includes a second sliding surface 32 that intersects with the first sliding surface 31 at an obtuse angle, to prevent the moving block 2 and the fixed block 1 from being misaligned along the adjustment direction perpendicular to the first adjustment surface 6 and the second adjustment surface 7. The second sliding surface 32 extends along the extension direction of the first sliding surface 31, wherein the second sliding surface 32 has an obtuse angle relative to the first sliding surface 31, so that the fixed block 1 and the moving block 2 maintain a state of engagement in the height direction in addition to mutual sliding, which can effectively prevent the mating surface 3 on the fixed block 1 and the moving block 2 from breaking apart during relative movement adjustment, and is suitable for driving and fastening the mold base that requires a stronger pre-tightening force.

[0026] Preferably, an elastic element 8 is sleeved on the end of the connecting rod 41 near the inner side of the connecting rod 41. The elastic element 8 is elastically connected between the end of the connecting rod 41 and the fixed block 1 or the moving block 2. The elastic element 8 is disposed between the end and the fixed block 1 or the moving block 2. When the connecting rod 41 is pulled by the other side, the elastic element 8 can play a buffering role, preventing the connecting piece 412 on the connecting rod 41 from being pulled quickly and colliding with the inner wall of the hole where the connecting piece 412 is located. This would cause wear during long-term use, resulting in excessive stroke error when screwing the threaded adjustment part 42, thus reducing the efficiency of use.

[0027] Reference Figure 6The included angle between the axes of the first sliding surface 31 and the connecting rod 41 is 15 degrees ± 15′. Preferably, the included angle of the inclined surface of the first sliding surface 31 is 15 degrees with the horizontal X direction of the moving block 2 relative to the fixed block 1. It should be noted that in this solution, the clamping and fixing of the mold base can be achieved by moving the moving block 2 relative to the fixed block 1 by only 1.7 mm in the horizontal Y direction.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
