Abstract
The utility model relates to a processing device for tube cold drawing, in particular to a cold drawing machine clamping device, which comprises a C-shaped support and a holding clamp which are arranged on a drawing carriage rail. The holding clamp is fixed on the C-shaped support, and the C-shaped support is provided with an electromagnet for controlling the holding clamp. The cold drawing machine clamping device has the advantages of simple and convenience operation, and capabilities of saving labor and time and increasing tube processing efficiency.
Description
Technical field
The utility model relates to a kind of tubing cold-drawn process equipment, especially a kind of drawbench clamping device.
Background technology
So-called cold-drawn processing is meant adopts withdrawing pattern that the direct cold-drawn of large diameter tubing is the tubing than minor diameter, and drawbench is in order to tubing is carried out a kind of plant equipment that tube reducing subtracts wall or subtracts wall hole enlargement processing.Existing drawbench carries out cold-drawn to the base pipe and adds man-hour, earlier to the processing of taking the lead of base pipe, to make the termination that can be pulled out the car clamping by drawbench, after the annealing mould is passed by the mode of ejector sleeve in the termination of base pipe, utilize again and pull out car the termination is clamped, by pulling out the car traction base pipe is extracted through mould then, decaptitate at last, cut away termination useless, in process, need clamping device to help because tubing is long, existing clamping device clamping effect is bad, the efficient height is changed in wearing and tearing easily.
The utility model content
The purpose of this utility model is to propose a kind of drawbench clamping device simple in structure, reasonable in design for the above-mentioned shortcoming that solves prior art.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drawbench clamping device comprises the C type support and the gripper clamp that are arranged on the drawing trolley track, and described gripper clamp is fixed on the C type support, and described C type support is provided with the electromagnet of control gripper clamp.
The purpose of this utility model can also further realize by following technology solution:
Aforesaid drawbench clamping device, wherein said gripper clamp is made up of two crossing tong arms, and the intersection location of described two tong arms flexibly connects by bearing pin and connecting plate, and described connecting plate is fixedlyed connected with C type support.
Aforesaid drawbench clamping device, the upper end of wherein said tong arm flexibly connects by connecting plate and the connecting axle that is located at the electromagnet lower end, is provided with the nylon cushion block in the lower end groove of described tong arm.
Aforesaid drawbench clamping device, when clamp position, wherein the angle between described two connecting plates is 160 °-180 ° under clamp position.
The utility model has the advantages that simple to operate, by the gripper clamp of magnet control the tubing of extracting is helped to avoid the tubing sag bent in the drawing process, the reliable difficult drop-off of clamping, drawbench clamping device of the present utility model in a word is simple to operation, save labour and time, improved the working (machining) efficiency of tubing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model drawbench clamping device structural representation.
Fig. 2 is the clamp position figure of the utility model drawbench clamping device.
Fig. 3 is the utility model drawbench clamping device work schematic diagram.
The specific embodiment
Embodiment one
The structure of present embodiment as depicted in figs. 1 and 2, a kind of drawbench clamping device, comprise the C type support 1 and the gripper clamp 2 that are arranged on the drawing trolley track, gripper clamp 2 is fixed on the C type support 1, C type support 1 is provided with the electromagnet 3 of control gripper clamp 2, gripper clamp 2 is made up of two crossing tong arms 21, the intersection location of two tong arms 21 flexibly connects by bearing pin and connecting plate 4, connecting plate 4 is fixedlyed connected with C type support 1, wherein the upper end of tong arm 21 flexibly connects by connecting plate 22 and the connecting axle 5 that is located at electromagnet 3 lower ends, the length of control connecting plate 22 forms it easily and rotates the dead point, tong arm 21 falls (see figure 2) when being electromagnet 3 dead electricity, angle angle between two connecting plates is 160 °-180 °, like this, and when on two tong arms 21, applying distraction force, two connecting plate 22 mutual diebacks form self-locking mechanism makes gripper clamp 2 can clamp tubing, electromagnet 3 adhesive when electric, two tong arms 21 of gripper clamp 2 are in open mode, are provided with nylon cushion block 23 in the lower end groove of tong arm 21 in addition.
Drawbench adds man-hour to the base pipe, tubing is advanced in the die cavity of withdrawing pattern and from die cavity, stretch out one section as the pull head part, tong chops on the drawing dolly 6 partly carries out clamping to the pull head of tubing, drawing dolly 6 is pulled out tubing under the effect of tractive force from die cavity, meanwhile, the electromagnet 3 of clamping device be in electric attracting state, two tong arms 21 of gripper clamp 2 are in open mode so that drawing dolly 6 passes through (see figure 3) under electromagnet 3 effects, drawing dolly 6 is whenever by a clamping device, just controlling two tong arms 21 that electromagnet 3 dead electricity make gripper clamp 2 near switch falls and forms self-locking mechanism clamping tubing securely, 23 pairs of tubing of the nylon cushion block of tong arm 21 lower ends are helped to prevent the tubing distortion, after tubing is all pulled out, control electromagnet 3 is opened gripper clamp 2 to carry out discharging, the tubing that unloads slides from the opening part of C type support 1, then tubing is carried out annealing in process, more mold exchange repeats above-mentioned steps until the finished product that obtains required size to change the die orifice size.
In addition to the implementation, the utility model can also have other embodiments, and for example gripper clamp can also be controlled by cylinder except by the magnet control.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the protection domain of the utility model requirement.
