Description

Technical Field

[0001] This utility model relates to the field of stamping fixture technology, and more specifically, to a stamping fixture for machine tool sheet metal parts. Background Technology

[0002] In the sheet metal stamping process of machine tools, clamping and lubrication are key factors affecting the forming quality. The clamping process can prevent displacement or offset caused by external forces, ensure the dimensional accuracy and positional tolerance of punching, bending and other processes, and achieve safe fixation. A reliable clamping device can avoid equipment damage or personal injury caused by material loosening during high-speed stamping. The lubrication process, as a lubricating medium, can form an effective oil film isolation layer during stamping, significantly reducing the friction coefficient between the sheet metal and the die, preventing surface scratches, cracks and other defects caused by material flow obstruction, and facilitating demolding of the sheet metal parts after stamping.

[0003] In existing machine tool sheet metal stamping processes, clamping and fixing mainly employs methods such as ordinary pneumatic clamping, hydraulic clamping, and mechanical clamps. Ordinary pneumatic and hydraulic clamping struggles to achieve precise pressure adjustment, easily leading to deformation of the machine tool sheet metal due to excessive clamping force or displacement of the workpiece due to insufficient clamping force. Mechanical clamping relies on manual labor, requiring personnel to enter the stamping device to bolt the sheet metal, which is not only inefficient but also poses safety hazards. The oiling process relies on traditional manual methods, resulting in low oiling efficiency and an inability to precisely control the oil film, easily leading to localized over- or under-oiling, affecting the stamping quality. Therefore, a stamping fixture for machine tool sheet metal is needed to solve the above problems. Utility Model Content

[0004] This invention aims to solve the problem that during the stamping of sheet metal parts on machine tools, manual entry into the stamping fixture is required for bolt tightening and manual oiling, which results in insufficient control of oil film thickness and excessive or insufficient oil in local areas on the workpiece surface.

The workbench has a cuboid structure, with a mold slot inside and two square slots symmetrically arranged inside. Each square slot is equipped with an oil pump, which is fixedly connected to the oil delivery hole. A slide rail is provided on the workbench.

[0007] Furthermore, the outer shell component includes: an outer shell, a second slide rail, and a fastening groove; the outer shell is a rectangular hollow structure, the second slide rail is provided on the outer shell, and the fastening groove is provided on the outer shell.

[0010] Furthermore, the transmission component includes: a transmission shaft, a gear, and a knob; the transmission shaft is movably connected to the housing via a bearing, a gear is fixedly mounted on the transmission shaft, the gear is movably connected to a spur gear, and a knob is fixedly mounted on the end face of the transmission shaft.

[0011] Furthermore, the stamping component and the ejection component include: a stamping cylinder, a stamping protrusion, an ejection cylinder, and an ejector pin; the stamping cylinder is fixedly installed on the upper surface of the housing, and a stamping protrusion is fixedly connected to the telescopic rod of the stamping cylinder.

[0013] Beneficial effects:

[0014] 1. In this utility model, the rotating block is mounted on the worktable via bearings, with some of its structure protruding from the worktable surface. The two rotating blocks are connected by a connecting column, which has an oil supply hole 2. When the machine tool sheet metal part is pushed into the stamping fixture, its gravity will press down on the rotating block and drive the connecting column to rotate, so that the originally vertical oil supply hole 2 is aligned and connected with the oil supply hole 1. The lubricant in the oil pump is precisely sprayed onto the surface of the machine tool sheet metal part through the oil supply hole 2 and the oil supply hole 1, which improves the oiling efficiency, accurately controls the oil film thickness, and avoids uneven oiling that affects the stamping quality.

[0015] 2. In this utility model, when the knob is rotated, the knob drives the gear to rotate through the transmission shaft. The gear drives the push block to move horizontally, and the push block pushes the fastening block to move along the fastening groove. At the same time, the fastening block generates a compound movement in the horizontal and vertical directions under the interaction of the slide groove two and the slide rail two, thereby firmly clamping the machine tool sheet metal parts of different thicknesses. The rotation of the knob can precisely adjust the clamping force. The knob is located on the outside of the housing, so the operator does not need to enter the stamping fixture to bolt the machine tool sheet metal parts, which improves the convenience of operation and enhances the safety of fixing.

[0034] In a specific embodiment: the connecting column 301 is a cylindrical structure, and rotating blocks 302 are fixedly installed on both end faces of the connecting column 301. The rotating blocks 302 are semi-cylindrical structures, and the end faces of the rotating blocks 302 are movably connected to the vertical plane of the worktable 101 through bearings.

The positions of the second oil supply hole 303 and the first oil supply hole 105 are corresponding. The spring provides elastic force to the rotating block 302 so that it is in a relatively fixed rotation angle when there is no external force. The second oil supply hole 303 and the first oil supply hole 105 are perpendicular to each other in space. When stamping the sheet metal parts of the machine tool, the rotating block 302 is flattened under the action of gravity, causing the connecting column 301 to rotate.

[0035] Preferably, the fastening component 4 includes: a push block 401, a first slide groove 402, a straight tooth 403, a top ball 404, a fastening block 405, and a second slide groove 406; the lower surface of the push block 401 is provided with a first slide groove 402, which is movably connected to a first slide rail 106; the upper surface of the push block 401 is provided with a straight tooth 403; a top ball 404 is fixedly installed on the end face of the push block 401, which is movably connected to the fastening block 405; the fastening block 405 is provided with a second slide groove 406, which is movably connected to a second slide rail 202.

[0036] Preferably, the transmission component 5 includes: a transmission shaft 501, a gear 502, and a knob 503; the transmission shaft 501 is movably connected to the housing 201 via a bearing, the gear 502 is fixedly mounted on the transmission shaft 501, the gear 502 is movably connected to the spur gear 403, and the knob 503 is fixedly mounted on the end face of the transmission shaft 501.

[0037] In a specific embodiment: the lower surface of the push block 401 is provided with a first groove 402, which is configured as a boss and is movably connected to the first slide rail 106. The boss-shaped connection means that the push block 401 can only move horizontally and cannot move vertically. The upper surface of the push block 401 is provided with straight teeth 403, which are all engaged with gears 502 fixedly installed on the transmission shaft 501. The end face of the push block 401 is fixedly installed with a top ball 404, which is movably connected to the fastening block 405. The fastening block 405 is provided with a second groove 406, which is movably connected to the second slide rail 202. Rotating the knob 503 outside the outer shell 201 drives the gear 502 to move, which drives the push block 401 to move and pushes the fastening block 405 downward. The fastening block 405 can be fixed to machine tool sheet metal parts of different thicknesses outside the stamping fixture, avoiding the safety hazards of manually entering the stamping fixture to bolt the sheet metal parts.

[0038] Working principle: The rotating block 302 in the oiling component 3 is movably connected to the worktable 101 via a bearing. Part of the rotating block 302 is higher than the upper surface of the worktable 101. The two rotating blocks 302 are connected by a connecting column 301, which has a second oil delivery hole 303. When the machine tool sheet metal part is pushed into the stamping fixture, the part, under gravity, presses against the rotating block 302. The rotating block 302 drives the connecting column 301 to rotate, causing the second oil delivery hole 303 and the first oil delivery hole 105 to switch from a spatially perpendicular state to a conductive state. The lubricating fluid in the oil pump 104 applies oil to the machine tool sheet metal part through the second oil delivery hole 303 and the first oil delivery hole 105, improving the oiling efficiency and enhancing the oil's performance. The precise control achieved by the membrane avoids local over- or under-oiling. Rotating the knob 503 drives the gear 502 to rotate via the transmission shaft 501. The rotation of the gear 502 causes the push block 401 to move horizontally, which in turn pushes the fastening block 405 to move on the fastening groove 203. The fastening block 405 moves horizontally and vertically in cooperation with the slide groove 406 and the slide rail 202, fixing machine tool sheet metal parts of different thicknesses. The rotation of the knob 503 can achieve precise control of the clamping force of the machine tool sheet metal parts. At the same time, the knob 503 is located outside the housing 201, eliminating the need for manual entry into the stamping fixture to bolt the machine tool sheet metal parts, thus improving the safety of fixing the machine tool sheet metal parts.
