Description

Technical Field

[0001] The present application relates to the field of machine tools, and in particular to a fixing fixture and a punching machine. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. The punches used in general punch presses are only fixed with bolts, but since the bolts need to be aligned with the threaded holes when using them, they cannot be operated when the light is dark or the space is small, which will affect the efficiency of installing the punches, resulting in reduced work efficiency.

[0003] For example, Chinese patent publication number CN218425136U discloses a fixture for fixing a punch on a punch press. When the T-shaped limit rod is inserted into the opening to limit the punch body in the first step, the bolt rod is just aligned with the position of the threaded hole. At this time, the bolt rod is rotated to rotate it into the threaded hole to further fix the punch body, ensuring the stability of the punch body during work. However, the top of the punch is limited by a buffer spring and a return spring. However, when the punch is punching, the buffer spring and the return spring will expand and contract, causing the punch to shake, thereby affecting the quality of the punch punching workpiece. Utility Model Content

[0004] In order to remedy the above deficiencies, the present application provides a fixing fixture and a punching machine, which aims to improve the problem that the buffer spring and the return spring will expand and contract when the punch is punching, causing the punch to shake, thereby leading to quality problems of the workpiece punched by the punch.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A mounting groove 110 is formed on the lower surface of the mounting seat 10 ; wherein, the fixing block 220 is installed inside the mounting groove 110 through the mounting groove 110 on the mounting seat 10 .

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The punch assembly 20 includes a punch 210, a fixing block 220, a fastening bolt 230 and a fastening block 240. Specifically, at least three fastening bolts 230 and fastening blocks 240 are provided to improve the stability of the fixed punch 210. The fixing block 220 is fixed to the top of the punch 210. A clearance groove is provided on the side of the fixing block 220. The fixing block 220 is provided inside the mounting groove 110 of the mounting seat 10. The fastening bolt 230 is screwed through the side of the mounting seat 10 and is rotatably connected to one side of the fastening block 240. The fastening block 240 is pressed against the side wall of the clearance groove provided on the side of the fixing block 220. A plurality of arc-shaped anti-skid bald heads 250 are equidistantly provided on one side of the fixing block 220 of the fastening block 240. Specifically, the arc-shaped anti-skid bald heads 250 are made of rubber material with good anti-skid performance. When installing, the fixing block 220 is placed inside the installation groove 110 so that the upper surface of the fixing block 220 contacts the top wall of the installation groove 110, so that the clearance groove is just close to the block 240, and then the abutting bolt 230 is rotated so that the abutting block 240 is close to the inside of the clearance groove, so that the fixing block 220 is fixed and installed. When replacing, the abutting bolt 230 is rotated again so that the abutting block 240 leaves the inside of the clearance groove of the fixing block 220, and the fixing block 220 can be taken out from the inside of the installation groove 110 to achieve replacement. By setting the abutting bolt 230 and the abutting block 240, the punch 210 can be fixed without shaking, further improving the quality of the stamped workpiece. At the same time, the punch 210 can be quickly installed and replaced, which is convenient for replacing punches 210 of different models, improving the practicality of the punch press 30, and being able to stamp workpieces of various specifications.

[0030] In this embodiment, the mounting seat 10 is located in the top of the mounting groove 110 and is fixedly connected with a clamping block 260, and the top of the fixing block 220 is provided with a clamping slot that matches the clamping block 260. When the fixing block 220 enters the inside of the mounting groove 110, the clamping block 260 enters the inside of the clamping slot, further improving the position of the clearance slot at the level of the abutting block 240, thereby improving the installation efficiency.

[0031] Furthermore, a retractable ball 270 is provided on the side of the clamping block 260, and specifically, at least three balls 270 are provided. The ball 270 is clamped with the side wall of the clamping slot of the fixed block 220. The side wall of the clamping slot of the fixed block 220 is provided with an arc groove, and the ball 270 is located inside the arc groove. When the clamping block 260 enters the inside of the clamping slot, the ball 270 is squeezed inwardly under the pressure of the fixed block 220, and when the fixed block 220 continues to move upward, the ball 270 falls into the inside of the arc groove to achieve clamping.

[0032] In the specific configuration, the mounting seat 10 and the fixing block 220 are connected to the side with auxiliary fixing members 280. Specifically, at least three auxiliary fixing members 280 are provided. The auxiliary fixing members 280 can further make the connection between the fixing block 220 and the mounting seat 10 more stable, thereby improving the stability of the punch 210.

[0033] Furthermore, the auxiliary fixing member 280 includes a first ear plate 281, a second ear plate 282 and a connecting bolt 283, wherein the first ear plate 281 is fixed to the outside of the mounting seat 10, the second ear plate 282 is fixed to the side of the fixing block 220, and the connecting bolt 283 is threadedly connected through the first ear plate 281 and the second ear plate 282. The connecting bolt 283 is connected to the first ear plate 281 and the second ear plate 282 to improve the stability of the connection of the punch 210.

[0034] In this embodiment, a countersunk hole 120 is provided on the side of the mounting seat 10, and the nut of the abutment bolt 230 is located inside the countersunk hole 120. The countersunk hole 120 allows the abutment bolt 230 to be located inside the mounting seat 10, thereby improving the aesthetics of the entire device.

[0035] See also Figure 1-Figure 5 The present application embodiment further provides a punch press, including the above-mentioned fixing fixture and the punch press 30, wherein the upper surface of the mounting seat 10 is fixedly connected to the punching end of the punch press 30. The punch press 30 is started so that the punch head 210 punches the workpiece, and a discharge assembly is provided under the workpiece support plate. The use method, working principle and specific structure of the punch press 30 are all prior art and will not be described in detail here.

[0036] During installation, the fixing block 220 is placed inside the installation groove 110 so that the upper surface of the fixing block 220 contacts the top wall of the installation groove 110, so that the clearance groove is just close to the block 240, and then the abutting bolt 230 is rotated so that the abutting block 240 is close to the inside of the clearance groove, so that the fixing block 220 is fixed and installed. During replacement, the abutting bolt 230 is rotated again so that the abutting block 240 leaves the inside of the clearance groove of the fixing block 220, and the fixing block 220 can be taken out from the inside of the installation groove 110 to achieve replacement. Through the arrangement of the abutting bolt 230 and the abutting block 240, the punch 210 can be fixed without shaking, further improving the quality of the stamped workpiece. At the same time, the punch 210 can be quickly installed and replaced, which is convenient for replacing punches 210 of different models, improving the practicality of the punch press 30, and being able to stamp workpieces of various specifications.
