Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically to a handheld electric clamping device for metal billets. Background Technology

[0002] During the movement of heated metal billets, manual operation using clamping devices is required. Some existing clamping devices rely on the operator's hand force for gripping, which can easily cause hand fatigue due to continuous force application. Furthermore, the gripping is not stable enough, creating safety hazards. Moreover, most existing clamping devices achieve billet gripping by adjusting the distance between the jaws, which only clamp the sides of the metal billet. Excessive clamping force can easily deform and damage the metal billet, while insufficient clamping force can cause the billet to fall from below, creating another safety hazard.

[0003] Therefore, how to provide a labor-saving and highly safe handheld electric clamping device for metal billets is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention aims to provide a handheld electric clamping device for metal billets to at least partially solve the problems of hand fatigue caused by clamping devices in the prior art, and the easy deformation or fall of billets during clamping.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A handheld electric clamping device for metal billets includes:

[0007] handle;

[0008] The mounting cavity is fixed to one end of the handle along its length.

[0009] An electric telescopic drive unit is fixed in the inner cavity of the mounting cavity, and its telescopic direction is arranged along the length direction perpendicular to the handle, and its telescopic end penetrates the end wall of the mounting cavity away from the handle.

[0010] The clamping part includes multiple sets of clamping assemblies arranged opposite each other along the circumferential direction of the electric telescopic drive unit. Each set of clamping assemblies includes a jaw, a driving rod, a first driven rod for driving the jaw to grip, and a second driven rod for driving the jaw to flip. The jaw includes a side baffle and a support plate. The support plate is arranged perpendicular to the side baffle and fixedly connected to one end of the side baffle. One end of the driving rod is hinged to the telescopic end of the electric telescopic drive unit. One end of the first driven rod is hinged to the outer wall of the mounting cavity, and the other end is hinged to the support plate near the side baffle. The middle part of the rod is hinged to the other end of the driving rod. One end of the second driven rod is hinged to the middle part of the rod of the driving rod, and the other end is hinged to the other end of the side baffle.

[0011] The beneficial effects of this utility model are as follows: The electric telescopic drive unit controls the clamping and opening of the gripping part, reducing the instability of relying solely on manual operation of the mechanical grippers and improving the automation level of production operations. Simultaneously, the electric telescopic drive unit extends and retracts, driving the active rod to rotate, which in turn drives the first and second driven rods to rotate, further rotating the side baffle and the support plate. This achieves the clamping of the billet. During clamping, the support plate supports the bottom of the billet, and the side baffle limits the movement of the billet around its perimeter, improving clamping stability and preventing the billet from falling during transfer. Especially when the billet is at a high temperature, this effectively improves the production safety of the operator.

[0012] Preferably, the end of the support plate away from the side baffle is fixed with an inclined insert plate whose thickness gradually decreases in the direction away from the support plate. This facilitates the insertion of the support plate from the bottom of the blank and its lifting.

[0013] Preferably, a reinforcing rod is also provided, one end of which is fixed to the middle of the outer wall of the mounting cavity, and the other end extends away from the mounting cavity and is fixed to the handle. This strengthens the load-bearing capacity of the handle and prevents it from breaking.

[0014] Preferably, the electric telescopic drive unit is fixed to the inner wall of the mounting cavity by bolts. This bolted connection facilitates the assembly and disassembly of the electric telescopic drive unit for easy maintenance.

[0015] Preferably, the device further includes multiple connectors for assembling the electric telescopic drive unit. These connectors are evenly spaced along the circumference of the mounting cavity and fixed to the inner wall of the mounting cavity. Each connector has a slot at its end away from the side wall of the mounting cavity, and the electric telescopic drive unit is fitted into the slot. Thus, the electric telescopic drive unit can be fixed by engaging with the slot, facilitating maintenance.

[0016] Preferably, the mounting cavity includes multiple uprights and a crossbar. The uprights are evenly spaced circumferentially and located on the outer periphery of the electric telescopic drive unit. Each upright is perpendicular to the length of the handle and fixed to one end of the handle along its length. The crossbar is fixed to the other end of the uprights, and the telescopic end of the electric telescopic drive unit passes through the crossbar and connects to the drive rod. Thus, the mounting cavity adopts a hollow frame design, reducing its weight.

[0017] Preferably, the electric telescopic drive unit is an electric telescopic rod. This facilitates control and enhances stability during clamping.

[0018] Preferably, a battery compartment is installed at the end of the handle away from the mounting cavity along its length, and the battery compartment contains a battery. Thus, the battery compartment and the mounting cavity are respectively installed at both ends of the handle, ensuring weight balance at both ends of the handle and reducing hand fatigue when holding the handle.

[0019] Preferably, the handle is provided with a control button, which is electrically connected to the battery and the electric telescopic rod. Thus, the opening, closing, and extension of the electric telescopic rod can be controlled by operating the control button.

[0020] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a handheld electric clamping device for metal billets. It uses an electric telescopic rod to drive the clamping part to clamp or open, which is easy to control and improves the stability during clamping, reduces the operator's operating intensity, and reduces hand fatigue. The side plate limits the side of the metal billet, and the support plate supports the bottom of the metal billet, which enhances the stability of the metal billet during clamping and prevents the billet from falling off. The battery compartment and the clamping part are respectively installed at both ends of the handle, which balances the weight, reduces the pressure on the hand when holding the handle, alleviates hand fatigue, and prevents hand injury.

[0029] Please see Figures 1-3 This utility model discloses a handheld electric clamping device for metal billets, including a handle 1, a mounting cavity 2, an electric telescopic drive unit 3, and a clamping unit 4.

[0030] The mounting cavity 2 is fixed to one end of the handle 1 along its length direction; the electric telescopic drive 3 is fixed in the inner cavity of the mounting cavity 2, and its telescopic direction is arranged perpendicular to the length direction of the handle 1 and its telescopic end passes through the end wall of the mounting cavity 2 away from the handle 1.

[0031] The clamping part 4 includes multiple sets of clamping assemblies evenly arranged along the circumferential direction of the electric telescopic drive part 3. Each set of clamping assemblies includes a jaw, a driving rod 41, a first driven rod 42 for driving the jaw to grip, and a second driven rod 43 for driving the jaw to flip. The jaw includes a side baffle 44 and a support plate 45. The support plate 45 is arranged perpendicular to the side baffle 44 and fixedly connected to one end of the side baffle 44. One end of the driving rod 41 is hinged to the telescopic end of the electric telescopic drive part 3 so as to rotate with the telescopic extension and retraction of the electric telescopic drive part 3. The first driven rod 42 is a bent rod, one end of which is hinged to the mounting cavity. 2. The outer wall, the middle bend of the rod body is hinged to the other end of the active rod 41. Under the drive of the active rod 41, it rotates to make the other ends of multiple first driven rods 42 move closer or further away from each other, clamping or releasing; one end of the second driven rod 43 is hinged to the middle of the rod body of the active rod 41, and the other end is hinged to the other end of the side baffle 44; so that the second driven rod 43 moves towards the center and towards the mounting cavity 2 under the drive of the active rod 41, thereby causing the side baffle 44 to flip towards the mounting cavity 2, and then causing the support plate 45 to flip to support the metal billet 9.

[0032] In some embodiments, a slanted insert plate 46, whose thickness gradually decreases in the direction away from the side baffle 44, is fixed to the end of the pallet 45, so that the pallet 45 can be smoothly inserted from the bottom of the metal billet and lift the metal billet. The side baffle 44, the pallet 45, and the slanted insert plate 46 are all made of high-temperature resistant materials, so that they can be used to clamp high-temperature metal billets in production processes such as rolling and forging.

[0033] In some embodiments, a reinforcing rod 5 is also provided. One end of the reinforcing rod 5 is fixed to the middle of the outer wall of the mounting cavity 2, and the other end extends away from the mounting cavity 2 and is fixed to the handle 1, thereby enhancing the firmness of the handle 1, strengthening the load-bearing capacity, and preventing the handle 1 from breaking due to overload of the head when clamping the metal blank.

[0034] In some embodiments, the electric telescopic drive unit 3 is fixed to the inner wall of the mounting cavity 2 by bolts, which facilitates the maintenance of the electric telescopic drive unit 3.

[0035] In other embodiments, when the outer wall of the electric telescopic drive unit 3 has a square structure, four connectors 6 for assembling the electric telescopic drive unit 3 are fixed circumferentially at uniform intervals on the inner side wall of the mounting cavity 2. Each connector 6 has a slot 61 at one end away from the side wall of the mounting cavity 2, and the right-angled side of the outer side wall of the electric telescopic drive unit 3 is adapted to be engaged in the slot 61.

[0036] In some embodiments, the mounting cavity 2 has a hollow structure to reduce its weight. It includes multiple uprights 21 and a crossbar 22. The multiple uprights 21 are evenly spaced around the periphery of the electric telescopic drive unit 3. Each upright is arranged perpendicular to the length direction of the handle 1 and fixed to one end of the handle 1 along its length direction. The crossbar 22 is fixed to the other end of the multiple uprights 21. The telescopic end of the electric telescopic drive unit 3 passes through the crossbar 22 and connects to the drive rod 41.

[0037] In some embodiments, the electric telescopic drive unit 3 is an electric telescopic rod, which is electric in nature and easy to use and control.

[0038] In some embodiments, a battery compartment 8 is installed at the end of the handle 1 away from the mounting cavity 2. The battery compartment 8 contains a battery, which is electrically connected to the control button 7. The battery is installed at the tail of the handle 1 and uses its own weight to balance with the clamping device at the front of the handle 1, reducing the force applied to the hand and relieving hand fatigue.

[0039] In some embodiments, a control button 7 is provided on the handle 1, and the control button 7 is electrically connected to the battery and the electric telescopic rod. The control button includes a power button, a clamping button, and a releasing button, and controls the extension, retraction, and closing of the electric telescopic rod.

[0040] Working principle:

[0041] In use, hold the handle 1 and move the device to the metal billet 9, turn on the power, press the clamping button, the electric telescopic rod retracts, thereby driving the driving rod 41 to move, which in turn drives the first driven rod 42 and the second driven rod 43 to move, so that the support plates 45 move closer to each other and the support plates 45 enter from the bottom of the metal billet 9. The support plates 45 continue to rotate upward to lift the metal billet 9 until all the support plates 45 are in the same plane. At this time, the side baffle 44 limits the metal billet from the side to prevent the billet from falling from the side gap. Move the handle 1 to move the metal billet 9 to the corresponding position, press the release button, the telescopic motor extends, thereby driving the structure to move in the opposite direction, the support plates 45 no longer support the metal billet 9, and the metal billet 9 falls to that position.
