Description

Technical Field

[0001] This utility model relates to the technical field of quenching equipment, and in particular to a movable clamping device for quenching plate parts. Background Technology

[0002] Sheet quenching is an important metal heat treatment process. It involves heating a sheet to a certain temperature and then rapidly cooling it to improve its mechanical properties, such as hardness, strength, and toughness. During the quenching process, clamping devices are needed to fix the sheet in the quenching equipment to ensure its stability during high temperature and cooling.

[0003] Existing patent publication number CN212833885U discloses a clamping mechanism for quenching sheet metal workpieces, including a horizontally arranged long plate, a first clamping mechanism vertically fixed at the bottom of the long plate, and a second clamping mechanism movably arranged at the bottom of the long plate. The first and second clamping mechanisms each include a vertically arranged first connecting rod and a second connecting rod, and the bottom of the first and second connecting rods are connected to symmetrically arranged clamping seats. This utility model uses two symmetrically arranged clamping seats to stably clamp and limit the two ends of the sheet metal workpiece. The water passage groove opened in the inner wall of the clamping seat can allow the side wall of the workpiece to contact the quenching liquid well. While stabilizing the clamping, it can also ensure the quenching effect. By using a stop block to isolate the inner wall of the clamping seat from the two ends of the workpiece, more gaps are created at the two ends of the workpiece, which facilitates the contact between the quenching liquid and the two ends of the workpiece, making the quenching reaction more complete and the quenching effect better.

[0004] Existing technology maximizes the quenching area of ​​the plate and reduces quenching dead zones by opening water channels in the inner wall of the clamp. However, some clamped parts still cannot make good contact with the quenching liquid, resulting in poor quenching effect of the clamped parts. Utility Model Content

The surfaces of the two sets of electric push rods 105 are fixedly connected to the support base 101. The electric push rods 105 drive the clamping plates 103 to move in opposite directions to clamp the plate.

[0031] The movable unit 200 includes several support plates 201 fixedly connected to the adjacent surfaces of two sets of clamping plates 103, and a rotating shaft 202 is rotatably connected between each pair of adjacent support plates 201.

A reciprocating component 207 is provided on the upper surface of the rack plate 205. The clamping plates 103 drive the rollers 203 to move and clamp the plate. By sliding the rack plate 205 inside the lifting groove 204, the gear 206 drives the rotating shaft 202 to rotate between the support plates 201, thereby causing the rollers 203 to rotate and drive the plate clamped by the rollers 203 to move up and down.

[0032] The reciprocating assembly 207 includes a support frame 207a fixedly connected to the upper surface of a set of clamping plates 103. A motor 207b is fixedly connected to the upper surface of the support frame 207a. A reciprocating screw 207c is fixedly connected to the output end of the motor 207b. The surface of the reciprocating screw 207c is rotatably connected to the support frame 207a. A reciprocating sleeve 207d is movably connected to the surface of the reciprocating screw 207c.

[0033] Furthermore, a limiting groove 207f is provided inside the support frame 207a, and a limiting block 207g is slidably connected to the inner wall surface of the limiting groove 207f. One side surface of the limiting block 207g is fixedly connected to the reciprocating slide sleeve 207d to limit the reciprocating slide sleeve 207d.

[0036] Furthermore, the connecting block 102 has a movable groove 106 inside, and the inner wall surface of the movable groove 106 is movably connected to the support frame 207a to avoid affecting the normal sliding of the support frame 207a and the clamping of the plate by the clamping plate 103.

[0037] During use, the electric push rod 105 is activated by the power supply to push the clamping plate 103 to slide in opposite directions inside the support base 101, causing the clamping plate 103 to move the roller 203 and clamp and fix the plate. Then, the motor 207b is activated by the power supply to drive the reciprocating screw 207c to rotate. The reciprocating sleeve 207d, which is movably connected to the reciprocating screw 207c, drives the connecting rod 207e to move up and down reciprocally. At the same time, the limiting block 207g, which is fixedly connected to the reciprocating sleeve 207d, slides within the limiting groove 207f. The rack plate 205, which is fixedly connected to the connecting rod 207e, slides up and down on the inner wall surface of the lifting groove 204. The gear 206, which meshes with the rack plate 205, rotates reciprocally. The support plate 201, which is fixedly connected to the gear 206, drives the roller 203 to rotate reciprocally, causing the plate clamped by the roller 203 to move up and down reciprocally, so that the clamped position of the plate can be better quenched and the quenching effect can be improved.
